Detailed Description
The utility model will be described in further detail with reference to the drawings and examples, it being noted that the examples described below are intended to facilitate the understanding of the utility model and are not intended to limit the utility model in any way.
Example 1
As shown in fig. 7, the blanking channel 3 of the blanking mechanism of the existing stretch film vacuum packaging machine is a vertical channel, after the packaged food is cut by the upper cutter assembly 1 and the lower cutter assembly 2 in a matched manner, the packaged food is discharged from the vertical blanking channel 3, but the blanking channels 3 cannot be orderly arranged in a scattered manner, so that the subsequent packaging links are not easy to implement automatic production. The main reason is that in punching blanking, after a punching cutter or a hob cuts a product, the product directly falls off, and the falling product is inclined, rolled and the like in the falling process, so that the falling product cannot be orderly arranged. In order to solve the technical problem, the application provides a specific embodiment of a blanking mechanism of a stretch film vacuum packaging machine, as shown in fig. 1, wherein the blanking mechanism comprises an upper cutter assembly 1 and a lower cutter seat assembly 2 for cutting packaged food; a blanking channel for the cut packaged food to fall down is arranged in the lower cutter holder assembly 2; the guide block 4 used for guiding the packaged food falling in the same initial falling posture is arranged in the blanking channel, so that the packaged food is discharged out of the blanking channel according to the same discharging posture.
"Having the same initial falling attitude" means that the attitude of the packaged food item that just starts falling when it is cut out is the same. The following description will take fig. 1, 4 and 7 as an example: in the figure, the packaged food is cut off and just begins to fall in the posture that the material box surface is arranged below and the material box surface is arranged above. "in the same discharge attitude" means that the attitude of the packaged food item when discharged from the blanking passage is the same, and is described by way of example in fig. 1 and 4: the posture of the packaged food falling on the conveyor belt 10 after being discharged is shown with the magazine face up and the magazine face down (i.e., the packaged food is turned 180 ° once during the falling process).
The packaged food refers to long or cuboid food such as donkey-hide gelatin, donkey-hide gelatin cake or spicy strips which are vacuum packaged by a stretched film, and is not applicable to packaged food such as spherical, elliptic and the like, such as marinated eggs, spherical ham and the like.
As a specific embodiment, as shown in fig. 2 and 5, the top of the guide block 4 is formed with an abutment 4-1 for contacting and blocking one side of the packaged food whose falling cutting edge is in a horizontal direction and adjusting the packaged food to a posture in which the cutting edge is not in a horizontal direction by the gravity of the packaged food itself. By "cutting edge is in a horizontal direction" is meant that the material cover is in a horizontal direction.
As shown in fig. 1, 2 and 5, when the packaged food is cut, the packaged food starts to fall, at this time, the cutting edge is in the horizontal direction (i.e., the material cover surface is in the horizontal direction), at this time, the packaged food hits the abutment portion 4-1 of the guide block 4 and is blocked, and thereafter, under the action of self gravity, the packaged food starts to turn in the direction of arrow a in fig. 2, that is, after the packaged food hits the abutment portion 4-1 of the guide block 4, the falling posture of the packaged food is adjusted such that the cutting edge (i.e., the material cover surface) is in the non-horizontal direction (i.e., the packaged food is high on the side near the guide block 4 and low on the other side).
The guide block 4 is provided with a slope part 4-2 at the lower part of the abutting part 4-1; the falling space 5 between the slope part 4-2 and the lower tool holder assembly 2 gradually contracts from top to bottom (i.e. the blanking channel forms the falling space 5 gradually contracts from top to bottom at the corresponding position of the slope part 4-2), and in the falling space 5, the packaged food cannot be turned over by 180 degrees or more. The purpose of gradual contraction of the drop space 5 from top to bottom is to further restrain the packaged food, and at the same time, no jamming occurs, so as to prepare for the posture when discharging the blanking channel 3. At the lowest part of the falling space 5, the packaged food cannot rotate by more than 90 degrees, so that the falling state of the materials is stable and is not scattered.
The joint between the abutting part 4-1 and the slope part 4-2 is an arc surface, so that the abutting part 4-1 can be prevented from damaging the fallen packaged food.
The guide block 4 is provided with a vertical constraint part 4-3 between the sliding-out slope surface 6 and the slope part 4-2, a falling constraint channel 8 is formed between the vertical constraint part 4-3 and the lower cutter holder assembly 2 (namely, a falling constraint channel 8 is formed at the corresponding position of the vertical constraint part 4-3 by a blanking channel), and in the falling constraint channel 8, the packaged food cannot rotate by more than 90 degrees.
In order to control the attitude when discharging the blanking channel, as shown in fig. 1 and 4, the lower part of the blanking channel is formed with a slide-out slope 6 for receiving the fallen packaged food and providing a slide-out blanking channel for the packaged food, and the blanking channel forms a slide-out channel 9 for the packaged food to slide out at the slide-out slope 6. The slide-out slope 6 is where the final discharge attitude (cartridge face up, cap down or cartridge face down, cap up) is determined when the packaged food slides out of the chute. The discharge attitude can be freely selected according to actual production requirements.
Based on the above-described technical solution, the falling space 5 (the space above the broken line a in fig. 2), the falling restraint channel 8 (the space between the broken line a and the broken line b in fig. 2), and the slide-out channel 9 (the space below the broken line b in fig. 2) together constitute a unique blanking channel in the blanking mechanism of the stretch film vacuum packaging machine of the present application.
Specifically, as a concrete form of the sliding-out slope surface 6, as shown in fig. 1 and 2, a slope block 7 is arranged at the lower part of the blanking channel, the outer surface of the slope block 7 is the sliding-out slope surface 6, and a sliding-out channel 9 is formed between the slope block 7 and the guide block 4. The slide-out ramp 6 in figures 1 and 2 allows the packaged food product to attain a top-down orientation of the cartridge surface. When the packaged food product enters the slide-out channel 9 from the fall restraint channel 8 and contacts the slide-out ramp 6, it starts to rotate in the direction of arrow B in fig. 2.
As another specific form of the slide-out slope 6, as shown in fig. 4, the slide-out slope 6 is formed by extending the lower portion of the guide block 4 in a direction away from the guide block 4. The slide-out ramp 6 in fig. 4 allows the packaged food product to attain a position in which the bin face is down and the bin face is up.
The shape of the guide block 4 can be freely designed and replaced according to different shapes of packaged foods, and the device can be applied to a larger range. For easy replacement, the guide block 4 is detachably connected with the lower tool holder assembly 2.
Example 2
On the basis of the embodiment 1, as shown in fig. 6, the utility model further provides a feeding mechanism assembly of the stretch film vacuum packaging machine, and specifically, the feeding mechanism assembly of the stretch film vacuum packaging machine comprises a plurality of feeding mechanisms of the stretch film vacuum packaging machine in the embodiment 1.
The present utility model is not limited to the above embodiments, but is capable of modification and variation in detail, and other modifications and variations can be made by those skilled in the art without departing from the scope of the present utility model.
