Abstract
Description
Technical Field
[0001] This utility model relates to the field of bag making machine technology, specifically a punching device for a bag making machine. Background Technology
[0002] In the production process of products such as plastic packaging bags and paper packaging bags, bag making machines need to punch holes in the bag body to meet the subsequent needs of threading ropes and ventilation. The packaging bags need to be conveyed during the punching operation.
[0003] Currently, traditional bag-making machine punching devices lack a tensioning mechanism in their conveying system, resulting in loose bags that negatively impact subsequent punching operations. Furthermore, the absence of a debris cleaning mechanism necessitates manual cleaning of the bags after punching, increasing labor intensity. Therefore, those skilled in the art have developed a bag-making machine punching device to address the problems described in the background section. Utility Model Content
[0004] The purpose of this invention is to provide a punching device for a bag making machine to solve the problems mentioned in the background art.

A unwinding roller is connected to the front of the first vertical plate. A set of tension rollers is connected to the front of the first vertical plate. A punching seat is connected to the upper surface of the worktable. A set of equally spaced punching slots is formed inside the punching seat. Two miniature cylinders are mounted on the upper surface of the worktable. The output ends of the two miniature cylinders are connected to a lifting seat. A set of equally spaced punching rods is connected to the bottom surface of the lifting seat. Two second vertical plates are connected to the upper surface of the worktable.

[0021] Please see Figures 1-5 In this embodiment of the present invention, a punching device for a bag making machine includes a workbench 1. A first vertical plate 2 is connected to the upper surface of the workbench 1. A winding roller 3 is connected to the front of the first vertical plate 2. A set of tension rollers 4 are connected to the front of the first vertical plate 2. A punching seat 5 is connected to the upper surface of the workbench 1. A set of punching slots 6 arranged at equal intervals are opened inside the punching seat 5. Two miniature cylinders 7 are installed on the upper surface of the workbench 1. The output ends of the two miniature cylinders 7 are connected to a lifting seat 8. A set of punching rods 9 arranged at equal intervals are connected to the bottom surface of the lifting seat 8. Two second vertical plates 10 are connected to the upper surface of the workbench 1. A set of first bearings 11 is embedded inside each of the two second vertical plates 10. The inner rings of the two sets of first bearings 11 are connected to first connecting rods 12. Wiping rollers 13 are connected to the outer surface of the connecting rod 12. A set of second bearings 14 is embedded inside the two second vertical plates 10. The inner rings of the two sets of second bearings 14 are connected to a conveying mechanism 15. The conveying mechanism 15 includes two second connecting rods 1501 and a servo motor 1503. The outer surface of the two second connecting rods 1501 is connected to a conveying roller 1502. The output end of the servo motor 1503 is connected to one end of one of the second connecting rods 1501. A set of tensioning rollers 4 are used to contact the surface of the raw material through their own rotation structure. The tension of the raw material is adjusted by the friction between the roller and the raw material. In this way, when the conveying speed of the raw material fluctuates, the tensioning rollers 4 can automatically compensate for the tension difference, avoid the raw material from wrinkling due to being too loose or breaking due to being too tight, and ensure that the raw material is in a flat state during subsequent punching.
[0022] The front of the first upright plate 2 is connected to a reinforcing base 16. The bottom surface of the reinforcing base 16 is connected to the upper surface of the workbench 1. A control button 17 and an emergency stop button 18 are installed on the front of the workbench 1. The first upright plate 2 can be reinforced by the reinforcing base 16, which makes the connection between the first upright plate 2 and the workbench 1 more secure. The emergency stop button 18 can immediately cut off the power of the device when the device malfunctions, thus preventing the accident from escalating.
[0023] One of the second upright plates 10 has an N-type support frame 19 connected to its back. The front of the N-type support frame 19 is connected to the back of the servo motor 1503. The bottom of the workbench 1 is connected to two sets of support legs 20. The two sets of support legs 20 are connected to a reinforcing inclined plate 21 on their sides. One end of each reinforcing inclined plate 21 is connected to the bottom of the workbench 1. A toolbox 22 is placed under the workbench 1. A handle 23 is connected to the front of the toolbox 22. The servo motor 1503 is fixed to the back of the second upright plate 10 through the N-type support frame 19, which isolates it from the material conveying area and prevents operators from contacting the rotating parts. The cooperation of the support legs 20 and the reinforcing inclined plate 21 can prevent the workbench 1 from tilting due to vibration during operation, ensuring that all parts are in a precise fit for a long time. Maintenance tools and vulnerable parts can be stored in the toolbox 22 under the workbench 1.
[0024] The working principle of this utility model is as follows: When using this device, the operator first places the rolled bag-making raw material onto the unwinding roller 3, and winds one end of the packaging bag through a set of tension rollers 4, while simultaneously passing it under the lifting seat 8. At the same time, one end of the packaging bag passes through the inside of two wiping rollers 13 and two conveying rollers 1502. At this time, the operator starts the device via control button 17. Two micro cylinders 7 work synchronously, driving the lifting seat 8 to descend vertically, causing a set of punching rods 9 on the bottom surface of the lifting seat 8 to move downwards. The punching rods 9 are precisely aligned with the equidistant punching slots 6 inside the punching seat 5, and the punching rods 9 insert into the punching slots 6 to complete the punching process of the raw material. After punching is completed, the micro cylinders 7 drive the lifting seat 8 to reset, waiting for the next punching cycle to complete the process. The punched raw material continues to be conveyed between two wiping rollers 13. The wiping rollers 13 are rotatably connected to the first bearing 11 in the second vertical plate 10 via the first connecting rod 12, and can rotate synchronously with the material conveying. The surface of the wiping rollers 13 is in contact with the upper and lower surfaces of the raw material. During the rotation, they wipe away punching debris, dust and other impurities from the surface of the raw material to prevent impurities from adhering and affecting the quality of subsequent bag making processes. The cleaned raw material enters the conveying mechanism 15. The servo motor 1503 in the conveying mechanism 15 starts, driving the second connecting rod 1501 connected to it to rotate, which in turn drives the conveying roller 1502 to rotate. The conveying roller 1502 is in close contact with the surface of the raw material, and uses friction to drive the raw material forward at a uniform speed, sending the punched raw material to the next bag making process. The above is the complete operation process of this device.
