Description

Technical Field

[0001] This utility model relates to the field of packaging bag punching technology, and in particular to a punching device for packaging bag processing. Background Technology

[0002] The function of a punching device for packaging bag processing is to accurately and efficiently punch the required holes in the packaging bag according to preset requirements and positions, so as to meet the various needs of the packaging bag in subsequent use, such as breathability, threading of ropes, and easy opening and closing.

[0003] A punching device for packaging bag processing, with publication number CN222987092U, uses a threaded column to initially clamp the raw material. Then, combined with a linkage clamping mechanism driven by an air pump to punch, the clamping force is enhanced. When the punch is pressed down, the arc-shaped connecting piece can drive the clamping plate to move down, which can ensure that the raw material can still be stably clamped at the moment of punching. This effectively avoids the displacement of the raw material at the moment of punching, thereby improving the accuracy and quality of punching and reducing the punching deviation and waste caused by the movement of the raw material.

[0004] The inventors discovered in their daily work that the aforementioned punching device for packaging bag processing only has a single punch, meaning that processing each hole requires separate operation. To process multiple holes on a single packaging bag, the bag's position must be repeatedly adjusted to align the punched area with the punch each time. This process is not only cumbersome but also time-consuming, especially during mass production, where this inefficiency is even more pronounced. More importantly, manual repetitive positioning makes it difficult to guarantee accuracy; each adjustment may introduce slight deviations, resulting in inconsistent spacing between multiple holes and severely impacting product quality. This high scrap rate due to inaccurate positioning wastes raw materials and increases production costs, clearly failing to meet the dual requirements of efficiency and quality for large-scale production and hindering the overall capacity improvement of the production line. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned above in the background art by proposing a punching device for packaging bag processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a punching device for processing packaging bags, comprising a support platform, two legs fixedly installed on the bottom surface of the support platform, a through groove opened on the surface of the support platform, an auxiliary device provided on the surface of the support platform, the auxiliary device comprising an L-shaped bracket fixedly installed on the surface of the support platform, a U-shaped frame fixedly installed on the surface of the L-shaped bracket away from the support platform, a cylinder fixedly installed on the top surface of the horizontal end of the U-shaped frame, a T-shaped plate fixedly installed on the output end of the cylinder, and multiple punches threadedly connected to the bottom surface of the T-shaped plate.

[0007] Preferably, slide rods are fixedly installed on both sides of the horizontal end of the L-shaped bracket, and a limit ring is fixedly installed on the end of the slide rod away from the L-shaped bracket. Slip rings are slidably connected to the outer wall surfaces of the two slide rods.

[0008] Preferably, both slip rings have hinge plates hinged to their annular sidewalls, and the end of the hinge plate away from the slip ring is hinged to a T-shaped plate.

[0009] Preferably, a PLC controller is fixedly mounted on the top surface of the horizontal end of the L-shaped bracket, and the PLC controller is electrically connected to the cylinder.

[0010] The effect achieved by the above components is that multiple punches can be used to process multiple holes on the packaging bag at one time, eliminating the tedious steps of adjusting the positioning multiple times required by the traditional single punch device, greatly shortening the processing time per cycle, and making it especially suitable for mass production scenarios, significantly increasing the processing volume per unit time.

[0011] Preferably, the surfaces of the vertical ends on both sides of the U-shaped frame are provided with a clamping device. The clamping device includes an extension plate fixedly installed on the surfaces of the vertical ends on both sides of the U-shaped frame. A sleeve is fixedly installed on the bottom surface of one of the extension plates, and a moving rod is slidably connected inside the sleeve.

[0012] Preferably, an electric telescopic rod is fixedly installed on the bottom surface of another of the extension plates, and a circular pressure plate is fixedly installed on the output end of the electric telescopic rod.

[0013] Preferably, the end of the moving rod away from the sleeve is fixedly connected to the circular pressure plate, and the surface of the circular pressure plate is provided with a clearance groove.

[0014] The above components achieve the following effects: the electric telescopic rod drives the circular pressure plate to move downward, which can firmly fix the packaging bag on the support surface. Combined with the anti-slip effect of the bottom silicone pad, it effectively prevents the packaging bag from slipping due to the force of the punch during the punching process, ensuring the accurate position of the hole and reducing deviation.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] In this invention, by setting up an auxiliary device, multiple punches can be used to process multiple holes on a packaging bag at once, eliminating the tedious steps of multiple positioning adjustments required by traditional single-punch devices, significantly shortening the processing time per cycle, and making it particularly suitable for mass production scenarios, significantly increasing the processing output per unit time; at the same time, the sliding cooperation between the slide rod and the slip ring, and the linkage design between the hinge plate and the T-plate, ensure the stability of the T-plate when driving the punch downward, avoiding hole position deviation caused by punch tilting, providing structural protection for punching accuracy, and reducing scrap caused by shaking.

[0023] Reference Figure 2-4As shown in this embodiment: An auxiliary device 2 is provided on the surface of the support platform 1. The auxiliary device 2 includes an L-shaped bracket 201 fixedly installed on the surface of the support platform 1. A U-shaped frame 202 is fixedly installed on the surface of the L-shaped bracket 201 away from the support platform 1. A cylinder 203 is fixedly installed on the top surface of the horizontal end of the U-shaped frame 202. A T-shaped plate 204 is fixedly installed on the output end of the cylinder 203. Multiple punches 205 are threadedly connected to the bottom surface of the T-shaped plate 204. Slide rods 206 are fixedly installed on both sides of the horizontal end of the L-shaped bracket 201. Limiting rings 207 are fixedly installed on the surface of the slide rods 206 away from the L-shaped bracket 201. Sliding rings 207 are slidably connected to the outer wall surfaces of both slide rods 206. 8. Both slip rings 208 have hinged hinge plates 209 on their annular sidewalls. The end of the hinge plate 209 away from the slip ring 208 is hinged to the T-shaped plate 204. A PLC controller 210 is fixedly installed on the top surface of the horizontal end of the L-shaped bracket 201. The PLC controller 210 is electrically connected to the cylinder 203. The cylinder 203 is model SC80-100, with a stroke of 80mm, a thrust of 800N, and a speed of 150mm / s. The punches 205 are made of high-speed steel, arranged in a straight line with a spacing of 30mm. The clearance between the slip ring 208 and the slide rod 206 is ≤0.2mm, and the sliding resistance is ≤5N. The PLC controller 210 is model S7-1200, and the signal delay is ≤0.3s.

[0024] Reference Figure 1-2 As shown in this embodiment: A clamping device 3 is provided on the surface of the vertical ends of both sides of the U-shaped frame 202. The clamping device 3 includes an extension plate 31 fixedly installed on the surface of the vertical ends of both sides of the U-shaped frame 202. A sleeve 32 is fixedly installed on the bottom surface of one extension plate 31, and a moving rod 33 is slidably connected inside the sleeve 32. An electric telescopic rod 36 is fixedly installed on the bottom surface of the other extension plate 31. A circular clamping plate 34 is fixedly installed at the output end of the electric telescopic rod 36. The end of the moving rod 33 away from the sleeve 32 is fixedly connected to the circular clamping plate 34. An clearance groove 35 is provided on the surface of the circular clamping plate 34. The electric telescopic rod 36 is model DTI-40, with a stroke of 50mm, a thrust of 400N, and a response time ≤0.5s. A 2mm silicone pad is pasted on the bottom of the circular clamping plate 34, with an anti-slip coefficient ≥0.9.

[0025] Working principle: When using this device, first check whether the support platform 1 is placed stably, whether the legs 4 are secure, and whether there is any debris accumulation in the through groove 5. Ensure that all components of the device are connected normally and without jamming. Then, lay the packaging bag to be punched flat on the surface of the support platform 1 and manually adjust its position so that the area to be punched is precisely aligned with the area directly below the multiple punches 205. At the same time, ensure that the area is directly above the through groove 5 so that the waste generated by punching can be smoothly discharged from the through groove. Then, send a signal through the PLC controller 210 to start the electric telescopic rod 36. The output end of the electric telescopic rod 36 pushes the circular pressure plate 34 downward. At this time, the moving rod 33 will slide synchronously along the inner wall of the sleeve 32 to provide stable guidance for the circular pressure plate 34 and prevent it from tilting. As the circular pressure plate 34 continues to move downward, the silicone pad at its bottom will tightly adhere to the surface of the packaging bag, thus pressing the packaging bag... The bag is firmly pressed onto the support platform 1 to prevent displacement of the packaging bag due to the force of the punch 205 during subsequent punching. After the packaging bag is stably pressed, the PLC controller 210 will delay for a short time to ensure that the pressing is in place. Then, the control cylinder 203 is started. The output end of the cylinder 203 pushes the T-shaped plate 204 downward. When the T-shaped plate 204 moves downward, it will drive the top hinge plate 209 to rotate synchronously. The hinge plate 209 pulls the slip ring 208 to slide along the slide rod 206 towards each other. The limit ring 207 can prevent the slip ring 208 from disengaging from the slide rod 206. This linkage structure ensures that the T-shaped plate 204 moves smoothly without tilting. At the same time, the multiple punches 205 at the bottom of the T-shaped plate 204 will move downward and pass through the avoidance groove 35 on the surface of the circular pressing plate 34 to quickly punch multiple holes in the packaging bag, achieving the effect of completing multiple punches in one operation. After punching is completed, the PLC controller 210 controls the cylinder 203 and the electric telescopic rod 36 to reset synchronously. The T-shaped plate 204 drives the punch 205 to move upward and away from the packaging bag. The circular pressure plate 34 moves upward and loosens the pressure on the packaging bag. At this time, the processed packaging bag can be taken out and placed into the next packaging bag to be processed to repeat the above process. Through the above process, the device realizes the rapid positioning, stable pressure and efficient multi-punching of the packaging bag, which greatly reduces the manual operation steps and positioning time. It is especially suitable for large-scale mass production and effectively improves punching efficiency and accuracy.
