[0002] Plastic packaging refers to packaging made of plastic. Plastic is primarily made of synthetic or natural polymer resins. By adding various additives, it becomes ductile under certain temperatures and pressures, and its shape can be fixed after cooling. Plastic packaging requires a crimping machine during production.

[0003] For example, an automatic crimping machine with authorization publication number "CN209776941U" features a simple structure, easy adjustment, and easily adjustable lamination temperature, enabling the production of bags that meet customer needs. However, this automatic crimping machine requires the operator to manually position the workpiece, making it inconvenient for the operator to use. Furthermore, after crimping, the automatic crimping machine requires the operator to cut the plastic packaging. This manual cutting process increases the crimping machine's operating time and reduces its efficiency. Utility Model Content

[0026] Working principle:

[0027] When it is necessary to press the edges of plastic packaging production:

[0028] Plastic packaging fixing stage:

[0029] First, the operator places the plastic package to be edge-pressed on the workbench 1, below the pressing plate 4. The operator then connects the external power supply to the first motor 201, starting the motor 201. This drives the threaded rod 202 to rotate, which in turn moves the flat plate 203. As the flat plate 203 moves on the first slide 204, it also moves the curved rod 3 on its surface, which in turn moves the pressing plate 4 downward. Once the pressing plate 4 has pressed the plastic part, the first motor 201 stops. The operator then heat-seals the plastic package using external heat-sealing equipment.

[0030] Trimming stage:

[0031] The fourth motor 6 is connected to an external power supply, the fourth motor 6 is started, and the fourth motor 6 drives the saw blade 7 to rotate.

The third motor 505 drives the reciprocating screw 506 to rotate. The reciprocating screw 506 drives the threaded block 508 to move on the third slide bar 507. At the same time, the threaded block 508 drives the fourth motor 6 to move. The fourth motor 6 drives the saw blade 7 to move. The saw blade 7 can cut different parts of the plastic package. After cutting is completed, the second motor 501, the third motor 505, and the fourth motor 6 are turned off. The first motor 201 then reverses. The first motor 201 uses the above-mentioned transmission method to drive the bending rod 3 to move the pressure plate 4 upward. After the pressure plate 4 is removed from the plastic package, the first motor 201 stops operating. The operator then removes the plastic package, completing the edge pressing work of the plastic package.
