Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] Implementation

[0025] Please see Figure 1 -4. A precision punching device for plastic packaging bags, comprising:

[0026] Support plate 1 and chassis 2;

[0027] A motor 3 is fixedly installed inside the support plate 1. A first gear 4 is fixedly installed at the output end of the motor 3. A fixed bearing 5 is fixedly installed inside the support plate 1. A power roller 6 is rotatably installed inside the fixed bearing 5. A second gear 7 is fixedly installed at one end of the power roller 6.

[0028] A spring 8 is fixedly installed inside the support plate 1, a telescopic rod 9 is fixedly installed inside the support plate 1, a connector 10 is fixedly installed at the bottom end of the spring 8 and the telescopic rod 9, a movable roller 11 is rotatably installed inside the connector 10, and a movable groove 24 is opened inside the support plate 1.

[0029] A control motherboard 12 is fixedly installed on the top of chassis 2, and a camera 13 is fixedly installed on the top surface inside chassis 2.

[0030] The technical solution provided in this embodiment is as follows: In use, the plastic packaging bag is first passed through the machine housing 2, then through the space between the movable roller 11 and the power roller 6. The spring 8 pushes the connecting piece 10 downwards, causing the movable roller 11 and the power roller 6 to squeeze the plastic packaging bag. The telescopic rod 9 restricts the movable roller 11 to move only up and down. Then, the main control board 12 starts the motor 3, which rotates the first gear 4 to drive the second gear 7 to rotate the power roller 6. This, in turn, causes the plastic packaging bag to unfold inside the machine housing 2 via the movable roller 11. Then, the motor 3 is stopped. The light 19 illuminates the area to be punched, and the camera 13 captures the image and transmits it to the control board 12 for analysis to determine if there is any deviation. After confirming that there is no deviation, the control board 12 activates the first hydraulic rod 17 to press down the pressure block 18, causing the punching part 20 to punch a hole in the plastic packaging bag. Then, the punching part 20 is inserted into the pre-drilled hole 22, and the punched plastic sheet enters the collection hopper 23 through the pre-drilled hole 22. Then, the second hydraulic rod 21 is activated to push out the plastic sheet inside the punching part 20 and let it fall into the collection hopper 23, thus completing the punching of the plastic packaging bag.

[0031] Furthermore, a fixing plate 14 is fixedly installed inside the support plate 1, a support column 15 is fixedly installed on the top of the fixing plate 14, and a base plate 16 is fixedly installed on the bottom of the support plate 1.

[0032] Specifically, by fixing the base plate 16 to the bottom of the support plate 1, the punching equipment can be better secured.

[0033] Furthermore, a first hydraulic rod 17 is fixedly installed inside the chassis 2, a pressure block 18 is fixedly installed at the bottom end of the first hydraulic rod 17, and a laser light 19 is fixedly installed at the bottom of the pressure block 18.

[0034] Specifically, by fixing the laser light 19 to the bottom of the pressure block 18, the laser light 19 can determine the punching position in advance when the punching equipment is punching, thus preventing the punching from deviating.

[0035] Furthermore, a punched part 20 is fixedly installed at the bottom of the pressure block 18, and a second hydraulic rod 21 is fixedly installed inside the pressure block 18, with the second hydraulic rod 21 located inside the punched part 20.

[0036] Specifically, by setting the second hydraulic rod 21 inside the punching part 20, after the punching part 20 punches the plastic packaging bag, the second hydraulic rod 21 can push out the punched round plastic fragments from the punching part 20, preventing the round plastic fragments from affecting the punching accuracy.

[0037] Furthermore, a pre-drilled hole 22 is provided on the bottom surface of the chassis 2, and a collection hopper 23 is fixedly installed on the bottom of the chassis 2.

[0038] Specifically, by opening the pre-drilled hole 22 on the inner bottom surface of the chassis 2, it is possible to better punch the plastic packaging bag, and also to press the punched plastic sheet into the inside of the collection hopper 23 through the pre-drilled hole 22.

[0039] Furthermore, there are multiple support columns 15, and the tops of the multiple support columns 15 are connected to the bottom surface of the chassis 2.

[0040] Specifically, by connecting the tops of multiple support columns 15 to the bottom surface of the chassis 2, the chassis 2 can be supported by the support columns 15, so that the chassis 2 will not shake during operation.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
