Description

Technical Field

[0001] This utility model relates to the field of packaging bag processing equipment technology, and more specifically, to a packaging bag punching device. Background Technology

[0002] During the production of packaging bags, some packaging products require punching to ensure air permeability.

[0003] Based on the above, the inventors have discovered that the punching waste generated after punching packaging bags by existing punching devices easily adheres to the punching needles, thus affecting the next punching action. This results in the punching action being unable to be continuous and effective, reducing production efficiency. At the same time, existing punching devices have low compression stability for packaging bags, which easily causes the packaging bags to slide during punching, thereby reducing the neatness and aesthetics of the punching and resulting in poor performance. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a packaging bag punching device with greater practical value. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a packaging bag punching device. It utilizes the cooperation of a limiting spring and a limiting bolt, so that when the punching cylinder presses down on the connecting plate and moves the mounting plate and pressure plate downwards, the limiting spring is compressed. Under the rebound force generated by the deformation of the limiting spring, the pressure plate firmly presses the packaging bag against the top surface of the base. This solves the problems of poor uniformity and aesthetics in traditional packaging bag punching, resulting in poor performance. Furthermore, the addition of an exhaust fan, along with the cooperation of the collection box and connecting pipe, enables the rapid removal of punching waste adhering to the punching needles, allowing the entire structure to continuously punch, greatly improving production efficiency.

[0006] 2. Technical Solution

[0015] 3. Beneficial Effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this solution, by setting the limiting spring and the limiting bolt, when the punching cylinder presses down the connecting plate, it can drive the mounting plate and the pressure plate to move down. When the pressure plate moves down to contact the base, the pressure plate and the mounting plate move relative to each other, and the limiting spring is compressed. Under the action of the rebound force generated by the deformation of the limiting spring, the pressure plate firmly presses the packaging bag to the top surface of the base, avoiding the slippage of the packaging bag, greatly improving the neatness and aesthetics of punching, and improving the use effect.

[0018] (2) In this scheme, by adding a blower, and with the cooperation of the collection box and connecting pipe, after the punching needle punches the packaging bag, the waste material is brought into the collection box. Then the blower works to generate a large suction force to draw the waste material into the waste bag. The whole operation realizes the rapid cleaning of the punching waste material adhering to the punching needle, so that the equipment can continuously complete the punching action, which greatly improves the production efficiency.

[0050] See Figure 3 The top of the punch 8 is fixedly connected to a pin 17, which extends to the top of the mounting plate 6 and is movably connected to a counterweight 18 on its outer periphery.

[0051] See Figure 3 A through hole 19 is provided on the top of the pressure plate 9 corresponding to the position of the punch 8, and the bottom end of the punch 8 passes through the pressure plate 9 through the through hole 19.

[0052] See Figure 3 The top of the base 1 has a positioning hole 20 corresponding to the position of the punching pin 8, and the positioning hole 20 is connected to the inside of the collection box 12.
