Detailed ways

The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and examples.

As shown in Figure 1-7, the wire package cutting machine includes a frame 1 and a controller. The frame 1 is provided with a loading mechanism 2 connected to the controller, a material transfer mechanism 3, a clamping mechanism 4, and a cutting mechanism. Mechanism 5. The material moving mechanism 3 receives the output end of the loading mechanism 2 and can move the wire package to the clamping mechanism 4. The cutting mechanism 5 can cooperate with the clamping mechanism 4 to cut the wire package.

The material transfer mechanism 3 transfers the wire package at the loading mechanism 2 to the clamping mechanism 4. The clamping mechanism 4 fixes the wire package to be cut. The cutting mechanism 5 cooperates with the clamping mechanism 4 to cut the wire package. The degree of automation of the present invention High, it can reduce manual repetitive tasks, reduce work intensity and improve work efficiency.

The feeding mechanism 2 includes a material channel 6, a pusher drive 7 that is movable and disposed in the material channel 6 to push materials at a fixed length, and an in-place detection device that cooperates with the pusher drive 7 to detect the output end wire package of the material channel 6. , the controller can control the work of the material transfer mechanism 3 according to the signal transmitted by the in-position detection device.

When loading materials, first arrange the wire packages in the material channel 6 in sequence, and the pusher drive 7 moves a fixed length in the material channel 6. For example, each time it pushes a fixed length to the output end of the material channel 6, the wires in the material channel 6 will be pushed. The wire packages are pushed to the output end one by one. In order to achieve precise loading of the wire package, an in-place detection device is provided in the loading mechanism 2. The in-position detection device uses detection to feedback a signal of whether the wire package is in place at the output end of the feed channel 6, and transmits the signal to the controller. The controller After receiving the signal, the material transfer mechanism 3 is controlled to work, and the wire package at the output end of the feed channel 6 is transferred to the clamping mechanism 4.

Wherein, the in-position detection device includes a push rod 8 and a detection probe 9 provided on the push drive 7. A first elastic member 10 is provided between the push rod 8 and the push drive 7. The detection probe 9 is used to sense the position of the pushing rod 8 .

Specifically, when the wire packages in the feed channel 6 are compactly arranged and pushed to the output end of the feed channel 6, the pusher drive 7 drives the pusher rod 8 and the detection probe 9 to move at a fixed length, and the pusher rod 8 compresses the first elastic member 10. The moving distance of the pusher rod 8 is less than the fixed-length movement distance of the pusher drive 7. At this time, the detection probe 9 detects the change in the position of the pusher rod 8, and the transfer mechanism 3 works to move the wire package at the output end. to the clamping mechanism 4.

Since the thickness of wire packages of different specifications and models will be different, the accumulated distance difference after pushing several wire packages will cause the arrangement of the wire packages in the feed channel 6 to not be compact. At this time, the pusher drive 7 drives the pusher rod 8 and the detection probe 9 moves at a fixed length. The pusher rod 8 does not compress the first elastic member 10. The distance that the pusher rod 8 moves is equal to the fixed-length movement distance of the pusher drive 7. The detection probe 9 does not detect the change in the position of the pusher rod 8 and the material is moved. Mechanism 3 does not work, and then the pusher drive 7 continues the next fixed-length movement, and so on, until the detection probe 9 detects the change in the position of the pusher rod 8.

The setting of the in-position detection device can realize the precise feeding of the wire package, and timely correct the distance difference during the pushing process of the wire package, so that different types of wire packages can be sent out through the material transfer mechanism 3, which has a reasonable structure and ingenious design , strong versatility.

The first elastic member 10 may be a spring disposed between the ejector rod 8 and the ejector drive 7 , or other elastic members existing in the prior art, which is not limited here. The arrangement of the first elastic member 10 can prevent the push rod 8 from rigidly acting on the wire package and damaging the product.

Specifically, the pusher drive 7 is provided with a mounting hole for the pusher rod 8 to pass through. The pusher rod 8 includes a T-shaped rod body and a push block detachably connected to the rod body. When assembling, first pass the rod body through the installation hole, then set the spring sleeve on the push rod 8, and finally install the push block on the end of the rod body. At this time, one end of the spring is connected to the pushing rod 8 and the other end is connected to the pushing drive 7 .

As shown in Figures 5 and 6, the material transfer mechanism 3 includes a material transfer plate 11 with an opening, and a material transfer drive 12 that drives the material transfer plate 11 to move. A magnetic attraction for positioning the wire package is provided on the side of the opening. Item 13.

In order to enhance the universal type and adapt to the positioning of wire packages with different inner diameters, the opening is set as a V-shaped opening.

A magnetic block 14 can also be disposed in the V-shaped opening. The magnetic force of the magnetic block 14 is greater than the magnetic force of the magnetic piece 13 so that wire packages with different inner diameters can be tightly attached to the V-shaped opening. In order to prevent the wire package from detaching from the opening, the end of the opening is bent inward to form an anti-detachment hook portion 15 .

As shown in Figure 7, the clamping mechanism 4 includes a first positioning rod 16, a second positioning rod 17, a first rotation drive 18 connecting the first positioning rod 16, and driving the first positioning rod 16 and the second positioning rod. 17 is close to or away from the clamping drive 19. There is an outer protrusion and an inner recess between the first positioning rod 16 and the second positioning rod 17. One of the outer protrusion and the inner recess is provided on the first positioning rod 16, and the other is One is provided on the second positioning rod 17.

When the material transfer mechanism 3 sends out the wire package, the second positioning rod 17 is inserted into the center of the wire package, and the clamping drive 19 drives the first positioning rod 16 and the second positioning rod 17 to approach each other to achieve clamping and fixation of the wire package. When the cutting mechanism 5 is working, the first rotary drive 18 drives the wire package to rotate and contacts the cutting mechanism 5 to achieve rotational cutting.

As shown in Figure 2, the cutting mechanism 5 includes a mounting block 20, a cutting knife device 21 slidably disposed on the mounting block 20, and a translation drive 22 connected to the mounting block 20. The cutting knife device 21 and the mounting block A second elastic member 23 is provided between 20. The translation drive 22 can drive the cutter device 21 to approach the clamping mechanism 4 and elastically contact the wire package on the clamping mechanism 4.

The cutter device 21 is slidably disposed on the mounting block 20. The second elastic member 23 between the cutter device 21 and the mounting block 20 enables the cutter device 21 to elastically contact the wire package. This elastic contact method effectively reinforces the It eliminates the problem of concentricity and can realize the cutting of wire packages of various specifications and models with different inner diameters. There is no need to constantly replace the slices. It has strong versatility and high work efficiency.

The cutter device 21 may be a circular cutter or a sawtooth cutter driven by the second rotation drive, which is not limited here.
