Description
Technical Field
[0001] This utility model relates to the field of food packaging bag technology, and in particular to a punching device for the production of food packaging bags. Background Technology
[0002] CN216708540U discloses a punching device for food packaging bag production. The device has symmetrically arranged protrusions on both sides of the top plate, with a T-shaped rod slidably inserted into the middle of each protrusion. The vertical part of the T-shaped rod passes through the protrusion and the extrusion plate in sequence. A limiting strip is provided on the bottom surface of the vertical part of the T-shaped rod. The operator manually lifts the T-shaped rod, and after the packaging bag is laid flat on the punching table, the operator releases the T-shaped rod. A spring fitted on the outer side of the vertical part of the T-shaped rod has good elastic potential energy. By fitting the spring on the T-shaped rod, the bottom surface of the rubber limiting strip can be better fitted to the packaging bag, preventing displacement of the packaging bag during punching.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0031] Please see Figure 1-5 As shown, this embodiment is a punching and cutting device for the production of food packaging bags, comprising:
[0032] The main component includes a worktable 1 and a support plate 28. The support plate 28 is fixedly connected to the upper end face of the worktable 1.
[0033] The stamping components include a top plate, a hydraulic rod 8, a stamping plate 7, a punching cutter 24, a connecting plate 6, a second toothed plate 5, a half gear 27, a feeding roller 4, a mounting plate 2, a food packaging bag body 3, a friction pad 29, a limit nut 26, a support foot 23, and an anti-slip pad.
[0034] A top plate 9 is fixedly connected to the upper end face of the support plate 28, a hydraulic rod 8 is fixedly connected to the lower end face of the top plate 9, a stamping plate 7 is fixedly connected to the telescopic end of the hydraulic rod 8, a punching blade 24 is fixedly connected to both sides of the lower end face of the stamping plate 7, a connecting plate 6 is fixedly connected to the left side face of the stamping plate 7, a second toothed plate 5 is fixedly connected to the side of the connecting plate 6 away from the stamping plate 7, a half gear 27 is connected to the surface of the second toothed plate 5, a feeding roller 4 is clamped to the inner wall of the half gear 27, an mounting plate 2 is fixedly connected to the left side face of the worktable 1, a food packaging bag body 3 is sleeved on the surface of the feeding roller 4, and a friction pad 29 is fixedly connected between the half gear 27 and the second toothed plate 5.
[0035] When the push block 12 slides along the upper part of the moving block 13 by controlling the telescopic cylinder 11, the inclined surface between the push block 12 and the moving block 13 can be used to push the moving block 13 to drive the fixed rod 14 to move downward. At the same time, the fixed rod 14 drives the lower part of the pressure plate 15 to abut against one side of the food packaging bag body 3 to press it down, so as to prevent the food packaging bag body 3 from shifting during processing. The process can be completed without manual operation. The telescopic cylinder 11 is set to model MXQ.
[0036] Two drive rollers 20 are provided, and both ends of the two drive rollers 20 rotate within the worktable 1.
[0037] When one of the drive rollers 20 is being driven, it drives the conveyor belt 21.
[0038] The surface of the movable block 13 slides on the inner wall of the fixed plate 10, and the left side of the movable block 13 is fixedly connected to the limit block 22;
[0039] The limiting block 22 can restrict the moving block 13 to prevent displacement from occurring with the fixed plate 10;
[0040] A reset spring 17 is fixedly connected to the lower end of the limiting plate. The bottom end of the reset spring 17 is fixedly connected to the upper end face of the worktable 1. The inner wall of the reset spring 17 is sleeved on the surface of the limiting rod 16.
[0041] Working principle: First, the operator drives the telescopic cylinder 11 to control the push block 12 to move towards the moving block 13. The inclined surfaces between the two push the moving block 13 downward, while simultaneously driving the fixed rod 14 and the pressure plate 15. During this process, the inner wall of the limiting plate will slide along the surface of the limiting rod 16, and the first gear 19 drives the first gear 19 downward, thereby rotating one of the transmission rollers 20. When the pressure plate 15 abuts against the top of the food packaging bag body 3, the return spring 17 is pressed to its limit. After the food packaging bag body 3 is processed, the telescopic cylinder 11 is driven again to control the push block 12 to move to the right, gradually escaping the pressure on the moving block 13. At this time, the return spring 17 begins to use its own elasticity to control the pressure plate 15 to move upward, so that the first toothed plate 18 drives the first gear 19 again and rotates the transmission roller 20 and the transmission belt, transporting the processed food packaging bag body 3 to other equipment.
[0042] Please see Figure 1-5 As shown, this embodiment is based on the above embodiment 1, and the stamping component includes a hydraulic rod 8, a stamping plate 7, a punching cutter 24, a connecting plate 6, a second toothed plate 5, a half gear 27, a feeding roller 4, a mounting plate 2, a food packaging bag body 3, a friction pad 29, a limit nut 26, a support foot 23, and an anti-slip pad;
[0043] A hydraulic rod 8 is fixedly connected to the lower end face of the top plate 9. A stamping plate 7 is fixedly connected to the telescopic end of the hydraulic rod 8. A punching cutter 24 is fixedly connected to both sides of the lower end face of the stamping plate 7. A connecting plate 6 is fixedly connected to the left side face of the stamping plate 7. A second toothed plate 5 is fixedly connected to the side of the connecting plate 6 away from the stamping plate 7. A half gear 27 is connected to the surface of the second toothed plate 5. A feeding roller 4 is clamped to the inner wall of the half gear 27. An mounting plate 2 is fixedly connected to the left side face of the worktable 1. A food packaging bag body 3 is sleeved on the surface of the feeding roller 4. A friction pad 29 is fixedly connected between the half gear 27 and the second toothed plate 5.
[0044] When the hydraulic rod 8 is driven, it can drive the stamping plate 7 and the connecting plate 6 to move downwards simultaneously. The connecting plate 6 drives the second toothed plate 5 to move, so that the second toothed plate 5 drives the half gear 27. When the punching cutter 24 abuts above the food packaging bag body 3, it realizes the cutting of the food packaging bag body 3. At the same time, the hydraulic rod 8 is set to model PWD14.
[0045] The front end of the feeding roller 4 is fixedly connected to the inner wall of the mounting plate 2. The surface of the feeding roller 4 is threaded with a limit nut 26, and one side of the limit nut 26 abuts against the surface of the half gear 27.
[0046] The limiting nut 26 can prevent the movement of the half gear 27 and prevent the half gear 27 from disengaging from the feeding roller 4.
[0047] The lower end face of the workbench 1 is fixedly connected to a support leg 23. There are four support legs 23, and the bottom of each of the four support legs 23 is fixedly connected to an anti-slip pad.
[0048] Working principle: (Reference) Figure 2 It can be seen that the length of the second toothed plate 5 is longer than that of the stamping plate 7 below. Therefore, when the hydraulic rod 8 controls the stamping plate 7 to move downward, the second toothed plate 5 first drives the second tooth, and the half gear 27 drives the feeding roller 4 to rotate, moving one side of the food packaging bag body 3 towards the worktable 1. After completion, the stamping plate 7 just drives the punching cutter 24 to abut against the surface of the food packaging bag body 3 to complete the punching. Subsequently, the hydraulic rod 8 starts to drive the stamping plate 7 and the connecting rod to move upward, so that the second toothed plate 5 contacts the friction surface between itself and the half gear 27, flipping the teeth to the position opposite to the second toothed plate 5, and repeating the operation.
