Description

Technical Field

[0001] This utility model relates to the field of bag making machine technology, specifically a bottom perforation device for a double-sided sealing bag making machine. Background Technology

[0002] A bag-making machine is a machine that produces various plastic or other material packaging bags. Its processing range includes packaging bags of various sizes, thicknesses, and specifications made of plastic or other materials. Generally, plastic packaging bags are the main product. During the processing of packaging bags, a punching device is needed to punch holes in the bottom of the packaging bag.

[0003] As shown in the reference case "A Bag Making Machine Capable of Perforation" (publication number CN216832493U), the sliding connecting rod allows for adjustment of the position of the perforator along the length of the support roller until the perforators at both ends of the support roller are adapted to the width of the conveyed plastic bag. Furthermore, sliding two perforators on the same connecting rod allows for adjustment of the distance between them, thus adjusting the perforation spacing of the plastic bag along the direction perpendicular to the length of the support roller. This enables convenient adjustment of the perforator position to adapt to the processing position of the plastic bag. According to the above references, although the device can improve the punching effect on packaging bags by adjusting the position of the punching machine on the support roller through the connecting rod, the packaging bags are prone to displacement due to the vibration generated by the operation of the device when punching holes in the punching machine. This results in low punching quality, making it inconvenient to accurately punch the packaging bags and reducing the effectiveness of the punching device of the double-sided sealing bag making machine. Summary of the Invention

[0004] Therefore, it is necessary to provide a bottom punching device for double-sided sealing bag making machines to address the problem of inconvenience in accurately punching holes in packaging bags.

[0005] To achieve the above objectives, a bottom punching device for a double-sided sealing bag making machine is designed, comprising a mounting frame. Both ends of the inner wall of the mounting frame are slidably connected to a movable main board. Several evenly arranged punching bodies are mounted on one end of one of the movable main boards. A placement groove is provided on one side of each punching body. A punching mechanism is provided on the inner wall of each punching body. The punching mechanism includes a cylinder mounted on the top of the punching body. A processing hole is provided at the top of the inner wall of the punching body. Moving blocks are slidably connected to both sides of the inner wall of the punching body. Two moving blocks are respectively positioned on either side of the processing hole. A limiting plate is slidably connected to the bottom of the inner wall of each moving block, with the bottom end of the limiting plate extending through to the outer wall of the moving block. Two return springs are fixedly connected to the top of each moving block, and the top ends of the return springs are fixedly connected to the inner wall of the punching body.

[0006] Furthermore, the punching mechanism also includes two telescopic rods fixedly connected between the moving block and the limiting plate. The outer wall of the telescopic rod is fitted with a compression spring, and pressure blocks are fixedly connected to both sides of the bottom of the cylinder.

[0007] Furthermore, a discharge pipe is fixedly connected to the bottom end of the punch body, and the discharge pipe is located below the processing hole.

[0008] Furthermore, the bottom end of the discharge pipe is threaded with a bottom cover.

[0009] Furthermore, two sliders are fixedly connected to the other side of the punch body, and the sliders are connected to the inner wall of one of the movable motherboards.

[0010] Furthermore, a number of evenly arranged fixing bolts are rotatably connected to one side of the movable motherboard, and one end of the fixing bolt passes through one of the movable motherboards and is threadedly connected to one of the sliders.

[0011] Furthermore, a material support plate is installed on one side of the other side of the movable motherboard, and the material support plate is positioned opposite to the installation position of the punch body.

[0012] Furthermore, a limiting bolt is installed on one side of the top of the material support plate, and one end of the limiting bolt passes through the material support plate and is threadedly connected to another movable main plate. Beneficial effects

[0013] Compared with the prior art, this utility model has the following advantages: (1) The movable motherboard of this utility model can move along the two linear guide columns on the mounting frame to adjust the position of the punch body. The punch body can move along the two guide rails inside the movable motherboard through two sliders. The packaging bag is placed in the placement slot. The punch body is driven by the cylinder to cooperate with the processing hole to punch the packaging. When one end of the cylinder moves downward, the moving block can be squeezed by two pressure blocks, so that the moving block drives the limiting plate to move downward, which can squeeze and fix the position of the packaging bag. As the pressure block moves, the limiting plate squeezes the telescopic rod and the compression spring, so that the telescopic rod and the compression spring generate a supporting force to support the limiting plate and prevent the packaging bag from shifting when punching. The moving block has a U-shaped structure and can move along the inner wall of the punch body. After punching, the two reset springs can stretch the moving block into the punch body and remove the packaging bag. After punching, the waste enters the discharge pipe. The waste can be centrally processed by rotating the bottom cover. The packaging bag can be punched quickly and accurately, which improves the punching effect of the punching device of the double-sided sealing bag machine. (2) In this utility model, multiple punching bodies move along the guide rail inside one of the moving main boards via two sliders on one side, which can adjust and move the punching position of the punching body. The position of the punching body can be fixed by rotating the fixing bolt in cooperation with one of the sliders. The material support plate at the other end of the mounting frame can place the packaging bag, which is convenient for punching the packaging bag. The limiting bolt can adjust and fix the position of the material support plate, which can improve the punching effect of the punching device of the double-sided sealing bag making machine on the packaging bag.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings: The following is combined Figure 1 - Figure 5 This invention describes a bottom perforation device for a double-sided sealing bag making machine.

[0017] In one embodiment, the bottom punching device of the double-sided sealing bag making machine includes a mounting frame 100. Both ends of the inner wall of the mounting frame 100 are slidably connected to a movable main board 200. Several evenly arranged puncher bodies 300 are mounted on one end of one of the movable main boards 200. A placement groove 310 is provided on one side of each puncher body 300. A punching mechanism 400 is provided on the inner wall of each puncher body 300. The punching mechanism 400 includes a cylinder 410 mounted on the top of the puncher body 300 for punching holes. A machining hole 420 is provided at the top of the inner wall of the punch body 300. Moving blocks 430 are slidably connected to both sides of the inner wall of the punch body 300. The two moving blocks 430 are respectively set on both sides of the machining hole 420. A limiting plate 440 is slidably connected to the bottom of the inner wall of the moving block 430. The bottom end of the limiting plate 440 extends through to the outer wall of the moving block 430. Two return springs 450 are fixedly connected to the top of the moving block 430. The top of the return springs 450 is fixedly connected to the inner wall of the punch body 300.

[0018] like Figure 2 , Figure 3 and Figure 4 As shown, the punching mechanism 400 also includes two telescopic rods 460 fixedly connected between the moving block 430 and the limiting plate 440. A compression spring 461 is sleeved on the outer wall of the telescopic rod 460. Pressure blocks 462 are fixedly connected to both sides of the bottom of the cylinder 410. A discharge pipe 470 is fixedly connected to the bottom end of the punch body 300. The discharge pipe 470 is located below the processing hole 420. A bottom cover 471 is threadedly connected to the bottom end of the discharge pipe 470.

[0019] In this embodiment, the cylinder 410 on the punch body 300 can drive the punch to cooperate with the processing hole 420 to punch holes in the packaging bag. When one end of the cylinder 410 moves, it drives two pressure blocks 462 to move and squeeze two moving blocks 430. The moving blocks 430 drive the limiting plate 440 to move downward along the inner wall of the punch body 300, so that the limiting plate 440 contacts the packaging bag and can squeeze and fix the packaging bag. As the pressure blocks 462 move, the limiting plate 440 squeezes the telescopic rod 460 and the compression spring 461. The pressure causes the telescopic rod 460 and the compression spring 461 to generate a supporting force to support the limiting plate 440, preventing the packaging bag from shifting during punching. The moving block 430 can be driven to return to its original position by two return springs 450. The waste generated by punching can enter the discharge pipe 470 for collection. Rotating the bottom cover 471 and the threaded connection of the discharge pipe 470 opens downwards, allowing for centralized processing of the waste. This allows for fast and accurate punching of the packaging bag, improving the punching effect of the punching device of the double-sided sealing bag making machine.

[0020] like Figure 2 and Figure 5As shown, two sliders 480 are fixedly connected to the other side of the punch body 300. The sliders 480 are connected to the inner wall of one of the movable main boards 200. Several evenly arranged fixing bolts 481 are rotatably connected to one side of the movable main board 200. One end of the fixing bolts 481 passes through one of the movable main boards 200 and is threadedly connected to one of the sliders 480. A material support plate 490 is installed on one side of the other movable main board 200. The material support plate 490 is opposite to the installation position of the punch body 300. A limit bolt 491 is installed on one side of the top of the material support plate 490. One end of the limit bolt 491 passes through the material support plate 490 and is threadedly connected to the other movable main board 200.

[0021] In this embodiment, the punch body 300 can move within one of the movable main plates 200 via two sliders 480 to adjust the position of the punch body 300. The punch body 300 can be fixed by rotating the fixing bolt 481, which is threadedly connected to one of the sliders 480. The material support plate 490 can slide along the top of the mounting frame 100 via the other movable main plate 200. The material support plate 490 can be fixed by rotating the limiting bolt 491, which is threadedly connected to the other movable main plate 200. This can improve the punching effect of the punching device of the double-sided sealing bag making machine on the packaging bag.

[0022] Working principle: Two movable main boards 200 can move along the two guide posts at the top of the mounting bracket 100 to adjust the position of the punch body 300 and the material support plate 490. Multiple punch bodies 300 slide on the inner wall of one of the movable main boards 200 via two sliders 480 to adjust the position of the punch body 300. Rotating the fixing bolt 481, which is threadedly connected to one of the sliders 480, can fix the punch body 300. Manually rotating the limit bolt 491, which is threadedly connected to the other movable main board 200, can fix the material support plate 490. The controller drives the cylinder 410 to move the punch downward to cooperate with the processing hole 420 to place the slot 3. The packaging bag is punched. When one end of the cylinder 410 moves, it drives two pressure blocks 462 to squeeze the moving block 430. The moving block 430 drives the limiting plate 440 to move downward along the inner wall of the puncher body 300 to squeeze and fix the packaging bag. As the cylinder 410 moves, the limiting plate 440 moves into the moving block 430 and squeezes the telescopic rod 460 and the return spring 450. After being squeezed, the telescopic rod 460 and the return spring 450 support the limiting plate 440. After punching is completed, the pressure block 462 moves upward, and the moving block 430 moves into the puncher body 300 through the two return springs 450, releasing the fixation of the packaging bag.
