[0022] Example: Refer to Figure 1-3The utility model discloses a corner cutting device for processing plastic ziplock bags, comprising a box body 1, the left and right sides of the top of the box body 1 are detachably connected with fixing parts 2, the tops of the two fixing parts 2 are fixedly connected with mounting plates 3, the mounting plates 3 provide a stable fixing point for the cutting mechanism above, ensuring that the cutting mechanism can maintain the necessary stability and accuracy during operation, the outer wall of the box body 1 is detachably connected with a connecting part 4, the top of the connecting part 4 is fixedly connected with a mounting part 5, the inner wall of the mounting part 5 is detachably connected with a motor 6, the mounting part 5 can cooperate with the connecting part 4 to provide support and installation space for the motor 6, the driving end of the motor 6 is fixedly connected with a bidirectional threaded rod 7, the tops of the two mounting plates 3 are fixedly connected with mounting blocks 8, the outer wall of the bidirectional threaded rod 7 is rotatably connected to the inner wall of the mounting block 8, the mounting block 8 can provide stability for the rotation of the bidirectional threaded rod 7, and the opposite sides of the two mounting blocks 8 are fixedly connected A fixed frame 9 is connected, which can provide protection for the movement of the two-way threaded rod 7. The outer wall of the two-way threaded rod 7 is connected to the outer wall of the fixed frame 9. The outer wall of the two-way threaded rod 7 is threadedly connected with moving blocks 10 on both sides. The motor 6 drives the two-way threaded rod 7 to rotate through its rotational movement. Since the two-way threaded rod 7 has the characteristics of left-right rotation, when it rotates, the two moving blocks 10 can move in opposite directions. When the two-way threaded rod 7 rotates in one direction, the two moving blocks 10 will separate or get closer, and when the two-way threaded rod 7 rotates in the opposite direction, the two moving blocks 10 will get closer or separate, so that it can quickly and accurately adjust the gap between the blades 18 to adapt to plastic bag materials of different thicknesses and sizes, ensure the high efficiency of the cutting process and product quality, and by adjusting the gap between the blades 18, it can reduce waste caused by inaccurate cutting and reduce production costs.
[0023] Reference Figure 1-4, mounting grooves 11 are provided on the left and right sides of the interior of the moving block 10, and moving rods 12 are slidably connected to the left and right sides of the outer wall of the moving block 10, and slide plates 13 are fixedly connected on the opposite sides of the moving rods 12, and the inner walls of the two mounting grooves 11 are slidably connected to the outer walls of the slide plates 13, and the outer walls of the two slide plates 13 are fixedly connected to slide rods 14, and the opposite sides of the two slide plates 13 are fixedly connected to a plurality of springs 15, and the inner walls of the two mounting grooves 11 are fixedly connected to the outer walls of the springs 15, and the bottoms of the two moving blocks 10 are detachably connected to fixed blocks 16, and the left and right sides of the two fixed blocks 16 are provided with slide grooves 17, and the outer walls of the two slide rods 14 are slidably connected to the inner walls of the slide grooves 17, and the bottoms of the two fixed blocks 16 are fixedly connected to blades 18, and the tops of the two blades 18 are arranged on fixed The bottom of the fixed frame 9 is squeezed to move the rod 12, so that the rod 12 pushes the slide plate 13 into the installation groove 11. When the slide plate 13 is pushed, the spring 15 is squeezed in the installation groove 11, and the spring 15 is deformed. At the same time, the slide plate 13 drives the slide bar 14 to leave the slide groove 17, so that the fixed block 16 and the blade 18 are separated from the upper device, thereby completing the rapid replacement of the blade 18. At this time, the moving rod 12 is released, and the spring 15 rebounds and pushes the slide plate 13, so that the slide plate 13 drives the slide bar 14 to reset. The rapid installation and removal of the blade 18 can reduce the time for replacing the blade 18 and improve production efficiency. Reducing the replacement time of the blade 18 means reducing the time of production interruption, thereby reducing production costs, and ensuring that a sharp blade 18 is used for each cutting, thereby ensuring product quality.
[0024] Reference Figure 1 A conveyor belt 19 is arranged on the top of the fixing part 2. The conveyor belt 19 is mainly used to transport the plastic ziplock bags to be cut to ensure a continuous and uniform work process. A plurality of load-bearing parts 20 are fixedly connected to the bottom of the box body 1. The main function of the load-bearing parts 20 is to support the entire equipment and ensure the stable operation of the machine. The bottom of the blade 18 is arranged on the top of the conveyor belt 19, so that better cutting can be performed.
[0025] Working principle: When in use, start the motor 6, and the driving end of the motor 6 will drive the bidirectional threaded rod 7 to rotate. Since the bidirectional threaded rod 7 has the characteristics of left-right rotation, its rotation can make the two moving blocks 10 move in opposite directions. Through the rotation of the bidirectional threaded rod 7, the gap between the two blades 18 can be quickly and accurately adjusted to adapt to plastic bag materials of different thicknesses and sizes, so that the gap between the blades 18 can be quickly and accurately adjusted, reducing the downtime caused by inappropriate gaps between the blades 18, thereby improving production efficiency. Appropriate gaps between the blades 18 can ensure that the edges of the ziplock bag are cut neatly and flat, improving the appearance quality of the product, and by adjusting the gaps between the blades 18, the gaps caused by cutting can be reduced. The scraps generated by inaccuracy can be reduced, and the production cost can be reduced. When the blade 18 needs to be replaced, the operator can squeeze the movable rod 12 so that the slide plate 13 squeezes the spring 15 in the installation groove 11 and deforms it. At the same time, the slide bar 14 will leave the slide groove 17, so that the fixed block 16 and the blade 18 are separated from the upper device. After releasing the movable rod 12, the spring 15 rebounds and pushes the slide plate 13 to reset, thereby realizing the rapid installation and removal of the blade 18. The rapid installation and removal of the blade 18 can reduce the time for replacing the blade 18 and improve production efficiency. Reducing the replacement time of the blade 18 means reducing the time of production interruption, thereby reducing production costs and ensuring that a sharp blade 18 is used for each cutting, thereby ensuring the quality of the product.
