Description

Cigarette package drying channel and drying device

Technical Field

The present invention relates to the field of cigarette packing, and more specifically, to a cigarette pack drying channel and a drying device.

Background Art

During the packaging and forming process of cigarette packs, the cigarette pack boxes are treated with glue and then enter the drying channel. While drying, they are transported to downstream equipment for subsequent packaging work.

The existing drying channel includes an upper pressing plate, a lower pressing plate and a conveyor belt, and the conveyor belt includes an upper belt attached to the upper pressing plate and a lower belt attached to the lower pressing plate. During the transportation of the cigarette pack in the drying channel, the cigarette pack is located between the upper belt and the lower belt, and the friction force applied to the cigarette pack by the conveyor belt drives the cigarette pack to move between the upper pressing plate and the lower pressing plate. The upper pressing plate and the lower pressing plate apply a certain pressure to the surface of the cigarette pack during the movement of the cigarette pack, so that the cigarette pack is shaped during the glue drying process.

However, the sizes of different cigarette packs are slightly different, which results in changes in the pressure applied by the upper and lower pressing plates to the cigarette packs. If the pressure applied by the upper and lower pressing plates to the cigarette packs is too great, the cigarette packs will be wrinkled or scratched; if the pressure applied by the upper and lower pressing plates to the cigarette packs is too small, the cigarette packs will not be well shaped, and the inner paper jam at the box cover will be exposed.

Therefore, how to provide a drying channel that can apply appropriate pressure to the cigarette packs during the drying process has become a technical problem that urgently needs to be solved in the field.

As shown in Figures 1 to 5, the cigarette package drying channel of the present disclosure comprises a pressing plate 1, a belt 2 and a plurality of groups of elastic pressing components 3. The elastic pressing components 3 are arranged between the pressing plate 1 and the belt 2.

The pressing plate 1 of the cigarette pack drying channel includes an upper pressing plate and a lower pressing plate, and the belt 2 includes an upper belt and a lower belt, the upper belt corresponds to the upper pressing plate, and the lower belt corresponds to the lower pressing plate.

The elastic pressing assembly 3 includes a first elastic member 31 and a second elastic member 32 .

The first elastic member 31 includes a first mounting portion 311 and a first elastic portion 312. The first mounting portion 311 is used to mount the first elastic member 312 on the pressing plate 1. The first elastic member 31 can be mounted on the pressing plate 1 by bolt connection or welding. The first elastic portion 312 is provided with a first pressing surface 31220, which abuts against the belt 2, and the first pressing surface 31220 is only used to apply pressure to the side of the box cover of the cigarette pack 100. The first elastic portion 312 is elastic, so that the pressure applied by the first pressing surface 31220 to the side of the box cover of the cigarette pack 100 can change as the size of the cigarette pack 100 changes.

The second elastic member 32 includes a second mounting portion 321 and a second elastic portion 322. The second mounting portion 321 is used to mount the second elastic member 32 on the pressing plate 1. The second elastic member 32 can be mounted on the pressing plate 1 by bolt connection or welding. A second pressing surface 32220 is provided on the second elastic portion 322, and the second pressing surface 32220 abuts against the belt 2, and the second pressing surface 32220 is used to apply pressure to the full box side of the cigarette pack 100. The second elastic portion 322 is elastic, so that the pressure applied by the second pressing surface 32220 to the full box side of the cigarette pack 100 can change as the size of the cigarette pack 100 changes. The full box side of the cigarette pack 100 refers to the side of the cigarette pack 100 as a whole, and the full box side includes the side of the box cover.

The first mounting portion 311 and the second mounting portion 321 at least partially overlap. The projection of the second pressing surface 32220 on the pressing plate 1 does not overlap with the projection of the first pressing surface 31220 on the pressing plate 1.

For a set of elastic clamping components 3, the first elastic member 31 and the second elastic member 32 should be installed on the same pressing plate 1, that is, the first elastic member 31 and the second elastic member 32 are both installed on the upper pressing plate, or the first elastic member 31 and the second elastic member 32 are both installed on the lower pressing plate. At the same time, the belt 2 that abuts against the first clamping surface 31220 and the second clamping surface 32220 is the belt corresponding to the pressing plate 1 on which the first elastic member 31 and the second elastic member 32 are installed, that is, when the first elastic member 31 and the second elastic member 32 are both installed on the upper pressing plate, the first clamping surface 31220 and the second clamping surface 32220 are both abutted against the upper belt, or when the first elastic member 31 and the second elastic member 32 are both installed on the lower pressing plate, the first clamping surface 31220 and the second clamping surface 32220 are both abutted against the lower belt.

In addition, the pressing plate 1 in the projection of the second pressing surface 32220 on the pressing plate 1 and the projection of the first pressing surface 31220 on the pressing plate 1 is the pressing plate on which the first elastic member 31 and the second elastic member 32 are installed.

In a specific implementation, the elastic pressing components 3 can be arranged at equal intervals, and the elastic pressing components 3 between the upper pressing plate and the upper belt and the elastic pressing components 3 between the lower pressing plate and the lower belt can be symmetrically arranged.

After the cigarette pack 100 enters the cigarette pack drying channel, it is driven by the belt 2 and moves along with the belt 2. While the cigarette pack 100 moves, the first pressing surface 31220 of each elastic pressing component 3 applies a variable elastic force to the side of the box cover of the cigarette pack 100, and the second pressing surface 3220 of each elastic pressing component 3 applies a variable elastic force to the side of the entire box of the cigarette pack 100.

The cigarette pack drying channel disclosed in the present invention applies elastic pressure to the cigarette pack 100 through the elastic pressing component 3, which can adapt to the changes in the size of the packaging boxes of different cigarette packs, and the two types of elastic parts can apply elastic pressure to the side of the box cover and the side of the entire box of the cigarette pack 100, effectively avoiding the problem of internal jammed paper being exposed.

In one embodiment of the cigarette package drying channel disclosed in the present invention, the first mounting portion 311 has a plate-like structure. The first elastic portion 312 includes a first bending section 3121 and a second bending section 3122. The first pressing surface 31220 is located on the second bending section 3122. The first bending section 3121 is connected to the first mounting portion 311, and the second bending section 3122 is connected to the first bending section 3121, and the angle between the first bending section 3121 and the first mounting portion 311 and the angle between the second bending section 3122 and the first bending section 3121 are both obtuse angles. The first elastic member 31 of this structure is conducive to providing continuous and effective pressure to the cigarette package 100. Moreover, as the cigarette package 100 moves relative to the first pressing surface 31220, the pressure applied to the cigarette package 100 by the first elastic member 31 also changes, thereby more effectively achieving the shaping of the cigarette package 100.

In a specific implementation, the first elastic member 31 can be manufactured by integral molding.

Furthermore, the first mounting portion 311 is provided with a first mounting hole 3110 for mounting the first elastic member 31 on the pressing plate 1. Through the first mounting hole 3110, the first elastic member 31 can be conveniently mounted on the pressing plate 1 by mounting members such as bolts.

Furthermore, a disassembly hole 3124 is provided at the connection between the first bending section 3121 and the second bending section 3122. The disassembly hole 3124 is provided corresponding to the first mounting hole 3110 on the first elastic member 31 of the adjacent elastic pressing assembly 3. A disassembly tool can conveniently disassemble mounting parts such as bolts through the disassembly hole 3124.

Furthermore, the first elastic part 312 also includes a third bending section 3123. The third bending section 3123 is connected to the second bending section 3122, and the third bending section 3123 extends toward the direction of the pressing plate 1, and the third bending section 3123 is arranged corresponding to the surface other than the second pressing surface 32220 of the adjacent second elastic part 322. The arrangement of the third bending section 3123 is conducive to dispersing part of the reaction force from the cigarette pack 100 when the reaction force on the first elastic part 312 is too large through contact with the second elastic part 322, thereby better protecting the elastic pressing assembly 3.

In one embodiment of the cigarette package drying channel disclosed in the present invention, the second mounting portion 321 has a plate-like structure. The second elastic portion 322 includes a fourth bending section 3221 and a fifth bending section 3222, and the second pressing surface 32220 is located on the fifth bending section 3222. The fourth bending section 3221 is connected to the second mounting portion 321, the fifth bending section 3222 is connected to the fourth bending section 3221, and the angle between the fourth bending section 3221 and the second mounting portion 321 and the angle between the fifth bending section 3222 and the fourth bending section 3221 are both obtuse angles. The second elastic member 32 of this structure is conducive to providing continuous and effective pressure to the cigarette package 100. Moreover, as the cigarette package 100 moves relative to the second pressing surface 32220, the pressure applied to the cigarette package 100 by the second elastic member 32 also changes, thereby more effectively achieving the shaping of the cigarette package 100.

In a specific implementation, the second elastic member 32 can be manufactured by integral molding.

Furthermore, the second mounting portion 321 is provided with a second mounting hole 3210 for mounting the second elastic member 32 on the pressing plate 1. Through the second mounting hole 3210, the second elastic member 32 can be conveniently mounted on the pressing plate 1 by mounting members such as bolts. In specific implementation, the second mounting hole 3210 and the first mounting hole 3110 can share a set of mounting members.

Furthermore, the second elastic portion 322 is provided with a slit 3223 extending along the length direction of the second elastic portion 322. The slit 3223 runs through the fourth bending section 3221 and the fifth bending section 3222. The provision of the slit 3223 can divide the second elastic portion 322 into two parts, and the two parts can respectively and relatively independently apply pressure to the cigarette package 100, thereby better meeting the requirements of the shaping of the cigarette package 100.

Furthermore, the slit 3223 is located in the middle of the second elastic portion 322 to apply pressure to the cigarette pack 100 in a more balanced manner.

The present disclosure also provides a drying device.

The drying device comprises the cigarette package drying channel disclosed in the present invention.
