Description

Technical Field

[0001] This utility model relates to the field of food preservation bag processing technology, specifically a device for processing the break points of plastic food preservation bags. Background Technology

[0002] Plastic bags are bags made primarily of plastic and are essential items in daily life. Food storage bags, as one of the most commonly used plastic bag products, are mainly used for preserving vegetables, fruits, grains, and cooked foods. The materials used for food storage bags include polyethylene, polyvinyl chloride, and polyvinylidene chloride. During the production process, cutting machines and sealing machines are typically used to process the rolls of food storage bags.

[0003] Chinese Patent CN219405641U discloses a tear-line processing device for food preservation bags, comprising: a base, a processing table, a top plate, a telescopic device, a lifting plate, a tear-line cutting blade, a pressure rod, and a connecting rod. The processing table is fixed to the upper surface of the base, the top plate is positioned above the processing table, the telescopic device is fixed to the top plate, and the lifting plate is fixedly connected to the telescopic rod of the telescopic device, with the lifting plate located below the top plate and above the processing table. Two sets of tear-line cutting blades are symmetrically fixed to the lower surfaces of the lifting plate on both sides of its center. The upper surface of the processing table has processing holes corresponding to the tear-line cutting blades. Two sets of pressure rods are each fixed to both ends of the lifting plate via the connecting rod. The pressure rods are located outside the tear-line cutting blades and the processing table, and are lower than the lower end of the tear-line cutting blades. This invention effectively alleviates the problem of tear-line deviation affecting product processing quality during traditional tear-line processing of food preservation bags.

[0004] However, the above technical solution has the following defects: the above-mentioned food preservation bag tear line processing device uses pressure bars on both sides to flatten the food preservation bag on the processing table, but the food preservation bag shifts on the processing table, which further causes the tear line to shift, affecting its use.

[0030] A fixed frame 3 is provided on the frame 1. The fixed frame 3 is located above the worktable 7. The fixed frame 3 is provided with a telescopic mechanism 5 for adjusting the height of the mounting frame 10. The mounting frame 10 is provided with a point-cutting knife 6 and a heating seal 11. The point-cutting knife 6 and the heating seal 11 are arranged side by side on the mounting frame 10.

[0031] Furthermore, the workbench 7 is provided with a groove 17, which corresponds to the position of the point-cutting knife 6. When the point-cutting knife 6 is working, it is embedded in the groove 17, making the cut point of the food preservation bag clearer and more complete, which is convenient for the actual use of the food preservation bag.

[0032] Furthermore, the telescopic mechanism 5 may be, but is not limited to, a hydraulic cylinder;

[0033] The frame 1 is rotatably equipped with a support roller 4 and a take-up roller 2. The frame 1 is equipped with a drive assembly a13 for driving the support roller 4 and the take-up roller 2 to rotate in the same direction. The support roller 4 and the take-up roller 2 are located on both sides of the worktable 7.

[0034] In this invention, the preservation bag is mounted on the support roller 4, and the other end of the preservation bag passes through the worktable 7 and is mounted on the take-up roller 2. The positions of the preservation bag on the support roller 4 and the take-up roller 2 correspond to each other to prevent the preservation bag from shifting during processing. The worktable 7 is equipped with a limiting component, which flattens the preservation bag on the surface of the worktable 7 for easy processing. The telescopic mechanism 5 drives the mounting frame 10 to move up and down reciprocally. The heating seal 11 on the mounting frame 10 seals the preservation bag. The point-cutting knife 6 performs point-cutting processing on the preservation bag. The processed parts are all wound onto the take-up roller 2. In this invention, the combination of the support roller 4, the take-up roller 2 and the limiting component keeps the preservation bag straight during processing and prevents the preservation bag from shifting on the worktable 7. The position of the limiting component can be adjusted according to the width of the preservation bag, making the device more versatile.

[0035] Example 2

[0036] like Figures 2-3 As shown, the plastic preservation bag break point processing device proposed in this utility model has two limiting components compared to the first embodiment. The two limiting components are slidably connected to the worktable 7 and symmetrically distributed on the worktable 7.

[0037] The limiting assembly includes a limiting rod 8 and a mounting part 14;

[0038] The mounting part 14 is slidably connected to the worktable 7. The mounting part 14 is located below the worktable 7. There are two limit rods 8, and both limit rods 8 are connected to the mounting part 14. The worktable 7 is provided with through holes corresponding to the positions of the limit rods 8, and the limit rods 8 pass through the through holes.

[0039] Furthermore, the projection shape of the limiting rod 8 is L-shaped.

The double threaded rod 16 is rotatably connected to the worktable 7. The worktable 7 is provided with a drive assembly b15. The drive assembly b15 is connected to the double threaded rod 16 through transmission. The mounting part 14 in the two limiting assemblies is threadedly connected to the double threaded rod 16.

[0042] In this embodiment, the two limiting rods 8 in the limiting assembly are located on both sides of the mounting frame 10, which can fix both sides of the break point position, so that the food bag is kept flat during processing and the position of the food bag on the workbench 7 is restricted. The driving component b15 in the adjustment mechanism drives the double threaded rod 16 to rotate, and the two mounting parts 14 move along the axis of the double threaded rod 16. The distance between the limiting components can be adjusted according to the width of the food bag, making the limiting components more applicable.

[0043] Example 3

[0044] like Figures 1-3 As shown, the plastic preservation bag break point processing device proposed in this utility model, compared with the first embodiment, has two tension rollers 9 rotatably mounted on the frame 1 in this embodiment, and both tension rollers 9 are located below the worktable 7.

[0045] The two tensioning rollers 9 are located between the support roller 4 and the worktable 7, and between the take-up roller 2 and the worktable 7, respectively.

[0046] In this embodiment, the unprocessed food storage bag is mounted on the support roller 4. The end of the food storage bag first passes around a tension roller 9 to reach the upper surface of the worktable 7, then passes around another tension roller 9 and connects to the take-up roller 2. The food storage bag is pressed against the outer circumference of the two tension rollers 9. The positions of the food storage bag on the support roller 4 and the take-up roller 2 correspond to each other to prevent the food storage bag from shifting during processing. The tension rollers 9 are located below the worktable 7. The two tension rollers 9 press the food storage bag tightly against the upper surface of the worktable 7 for easy processing.

[0047] It should be noted that all electrical appliances used in this utility model are models that can be directly purchased on the market, and their specific working principles are existing technologies that are well known to those skilled in the art, so they will not be described here.
