[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-5 This utility model discloses a punching device for paper bag production, comprising a housing 1, with support columns 2 at each of the four corners of the bottom of the housing 1. Transmission mechanisms are horizontally arranged on both sides inside the housing 1, and a punching mechanism is located inside the housing 1 between two transmission mechanisms. A sliding groove 5 is provided above the middle of the housing 1, and a sliding seat for mounting the punching mechanism is installed in the sliding groove 5. The support columns 2 provide stable support for the housing 1, ensuring smooth operation of the equipment. A pull-out opening is provided in the middle of the front face of the housing 1, and a waste hopper 3 is provided inside the pull-out opening. A handle 4 is provided on the front face of the waste hopper 3, and a top of the waste hopper 3 is provided with... The material discharge plate 11, through the setting of the waste hopper 3, facilitates the collection and cleaning of waste materials; the transmission mechanism includes an upper conveyor belt 7 inside the upper part of the horizontal housing 1 and a lower conveyor belt 8 set below the upper conveyor belt 7. The two ends of the inner circle of the upper conveyor belt 7 are each equipped with a first drive shaft, and the two ends of the inner circle of the lower conveyor belt 8 are each equipped with a second drive shaft. The ends of the first drive shafts are rotatably connected to the inner wall of the housing 1 through bearing rings. The outer ends of the upper conveyor belt 7 are all inclined upwards. Through the setting of the transmission mechanism, efficient material conveying and positioning can be achieved, which helps the subsequent drilling operation.

[0020] In this invention, the front end of one of the first drive shafts in the transmission mechanism is connected to a first motor 6 mounted on the housing 1, and the front end of one of the second drive shafts in the transmission mechanism is connected to a second motor mounted on the housing 1. This connection of the first motor 6 provides a stable power source, ensuring the normal operation and speed control of the conveyor belt. The punching mechanism includes a first electric push cylinder 9 vertically installed in a slot at the bottom of the sliding seat, a telescopic arm 12 located at the bottom of the first electric push cylinder 9, and a punching head 13 installed at the bottom of the telescopic arm 12. The top of the sliding seat extends from the sliding groove 5, and both sides of the upper part of the sliding seat are equipped with… The protrusion has its bottom surface slidingly attached to the top surface of the casing 1. A locking bolt 10 is inserted through the center of the top surface of the protrusion, and the bottom end of the locking bolt 10 abuts against the top of the casing 1. Through the setting of the punching mechanism, precise punching operation can be achieved, and the position and depth can be adjusted as needed. Both sides of the punching head 13 are equipped with longitudinally rotating pressure rollers 15. The front and rear ends of the pressure rollers 15 are rotatably connected to vertically placed electric telescopic rods 14. The fixed end of the electric telescopic rod 14 is fixedly connected to the inner top surface of the casing 1. Through the setting of the pressure rollers 15 and the electric telescopic rods 14, appropriate clamping force can be applied to the paper bag to ensure the stability and accuracy of punching.

[0021] Working Principle: When using this invention, firstly, the first motor 6, the second motor, and the first electric pusher cylinder 9 are energized, starting the first motor 6 and the second motor, causing the upper conveyor belt 7 and the lower conveyor belt 8 to start operating. The paper bag to be punched is placed at the entrance end between the upper conveyor belt 7 and the lower conveyor belt 8. The paper bag begins to be conveyed into the machine box 1 under the action of the conveyor belts. The paper bag moves towards the middle of the machine box 1 along with the conveying mechanism. When the paper bag reaches the punching position, the first electric pusher cylinder 9 is activated under the action of the control system, pushing the telescopic arm 12 downward, and the punching head 13 descends accordingly to punch the paper bag. During the punching process, the electric telescopic rod 14 is activated to extend, thereby driving the pressure roller 15 downward. The paper bags to be punched are pressed down on both sides to keep them flat and stable, preventing them from shaking during punching and ensuring punching accuracy. At the same time, the punching mechanism can be finely adjusted on the sliding groove 5 according to the position of the paper bags to further improve punching accuracy. The waste generated from punching falls into the waste hopper 3 through the discharge plate 11. The waste hopper 3 collects the waste. When the waste hopper 3 is almost full, it can be cleaned by pulling the waste hopper 3 with the handle 4. The punched paper bags continue to move forward under the action of the transmission mechanism and are discharged from the outlet on the other side of the machine box 1 to complete the punching operation. After all the punching work of paper bag production is completed, the power of the first motor 6, the second motor and the first electric push cylinder 9 is turned off, and the device is cleaned and maintained.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
