The movable plate returns to its initial position under the elastic action of the spring, so that the roller fits with the placement plate to press the plastic bag, and then the screw rod is rotated, and the screw rod rotates to drive the threaded block to move, and the threaded block drives the cylinder to move through the fixed seat, thereby punching the plastic bag. The position of the punching needle is adjusted. After the adjustment is completed, the cylinder is turned on by the external controller. The cylinder drives the punching needle to move downward, and the punching needle is inserted into the punching groove inside the placement plate to punch holes in the plastic bag. At the same time, since the plastic bag is pressed by the roller, when the punching position of the plastic bag needs to be changed, the plastic bag can be directly pulled. The roller can always maintain the pressing effect on the plastic bag under the elastic action of the spring. The pulling plate is fixed by the fixing rod, and the movable plate is conveniently pulled by the pulling plate, which is convenient for placing and taking out the plastic bag. The support seat is supported and fixed by the fixing block, and the support seat supports the screw rod. The screw rod is conveniently driven to rotate by the motor, and the fixing frame is supported and fixed by the fixed leg. However, the following defects still exist:

[0003] Due to the different models of plastic bags, when the width of the plastic bag is small, it is inconvenient to compress the plastic bag, resulting in poor punching effect of the plastic bag. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Embodiment 1, by Figure 1-4 The utility model relates to a punching device for plastic bag production, comprising a punching platform 1, a top frame 2 being installed on the top of the punching platform 1, a puncher 3 being provided above the punching platform 1, the top of the puncher 3 being fixedly connected to the output end of a first cylinder 4, the first cylinder 4 being fixedly installed on a mounting frame 5, a movable drive module 6 being installed between the mounting frame 5 and the top frame 2, the movable drive module 6 being capable of driving the puncher 3 to move along the X-axis and the Y-axis, and a plastic bag pressing assembly 7 being installed on the top of the punching platform 1.

[0024] The plastic bag pressing assembly 7 includes vertical plates 701 symmetrically mounted on both sides of the top of the punching platform 1. A mounting plate 702 is provided on the side where the two vertical plates 701 are close to each other. A transverse plate 704 is mounted on the top of the mounting plate 702. The side of the mounting plate 702 close to the vertical plate 701 is fixedly connected to the output end of the second cylinder 703. The second cylinder 703 is fixedly mounted on the side of the vertical plate 701 away from the mounting plate 702. A plate groove 708 is provided on the transverse plate 704. A movable plate 709 is slidably mounted inside the plate groove 708. The bottom end of the movable plate 709 is mounted with a The pressure roller frame 712 is located below the transverse plate 704. A pressure roller body 713 is installed on the pressure roller frame 712. The material of the pressure roller body 713 is rubber. An end plate 710 is installed on the top of the movable plate 709. The length of the end plate 710 is greater than the length of the plate groove 708. The end plate 710 is located above the transverse plate 704. A spring 711 is symmetrically installed at the bottom end of the end plate 710. The bottom end of the spring 711 is fixedly connected to the top wall of the transverse plate 704. A top plate 705 is provided above the end plate 710. The bottom of the top plate 705 is fixedly connected to the top wall of the transverse plate 704. The ends of the two support plates 706 are symmetrically installed. The bottom end of the support plate 706 is fixedly connected to the top wall of the horizontal plate 704. The movable plate 709 is located between the two support plates 706. The top of the top plate 705 is fixedly installed with a third cylinder 707. The output end of the third cylinder 707 passes through the bottom of the top plate 705. The output end of the third cylinder 707 contacts the top wall of the end plate 710. The pressure roller body 713 is rotatably installed on the pressure roller frame 712, which is convenient for the plastic bag to be pressed under the pressure roller body 713 or to be unloaded after punching. At the same time, the material of the pressure roller body 713 is rubber. When punching, the output end of the third cylinder 707 generates pressure on the pressure roller body 713, causing the pressure roller body 713 to deform and its bottom wall to form a plane, thereby increasing the pressing effect on the plastic bag and improving the punching stability of the plastic bag. The mounting plate 702 is fixedly connected to the output end of the second cylinder 703, and the output end of the second cylinder 703 is controlled to move outward, thereby pushing the mounting plates 702 on both sides to adjust their positions, so that the pressure roller body 713 can move to the position to press the plastic bag, thereby facilitating the punching of plastic bags of different types and improving the punching efficiency.

[0025] Working principle: When working, first place the plastic bag to be punched flat on the top of the punching platform 1 so that the plastic bag is located below the pressing roller body 713 to limit the position of the plastic bag;

[0026] When it is necessary to punch a hole in the plastic bag, the mobile driving module 6 drives the puncher 3 to move above the position where the hole needs to be punched in the plastic bag, and then controls the output end of the first cylinder 4 to extend, thereby pushing the puncher 3 to move downward to punch the hole;

[0027] During punching, the output end of the third air cylinder 707 is controlled to move downward, exerting downward pressure on the pressure roller body 713. Since the pressure roller body 713 is made of rubber, the pressure roller body 713 deforms under the action of pressure, and its bottom wall becomes flat, thereby increasing the compression effect on the plastic bag and improving the stability of the punching of the plastic bag.

[0028] When the widths of the plastic bags are different, the output end of the second cylinder 703 is controlled to move outward, thereby pushing the mounting plates 702 on both sides to adjust their positions, so that the pressing roller body 713 can move to a position to press the plastic bags, thereby facilitating punching of plastic bags of different types and improving punching efficiency.
