Description

Technical Field

[0001] The utility model relates to the technical field of plastic bag production, in particular to a perforating device for plastic bag production. Background Art

[0002] Plastic bags are bags made of plastic (commonly used plastics include polypropylene, polyester, nylon, etc.) as the main raw material. They are indispensable items in people's daily lives and are often used to hold other items. When plastic bags are produced, they need to be perforated by a perforating device.

[0003] For example, the application publication number CN219947453U discloses a punching device for plastic bag production, comprising a fixing frame, a placement plate disposed inside the fixing frame, a holding assembly disposed above the placement plate, a screw disposed above the fixing frame, and a threaded block threadedly connected to the outer side of the screw. Although the above document solves the problem of the difficulty in flexibly adjusting the punching position of the existing device, after the plastic bag is fixed by the pressing plate, when the punching position of the plastic bag needs to be adjusted, it is necessary to manually pull the handle to raise the pressing plate and then move the plastic bag, which is a cumbersome operation and inconvenient to use.

[0004] However, when using the existing perforating device, the plastic bag is placed on the placement plate, the plastic bag is fixed by the holding components on both sides, and then the plastic bag is perforated by the punching needle. Since the distance between the holding components on both sides is fixed, only plastic bags of the same width can be fixed and then perforated, thereby reducing the working range of the existing perforating device. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a perforating device for plastic bag production.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] Preferably, the adjusting device includes a connecting plate, the outer wall of the connecting plate is fixedly connected to a handle, the side of the connecting plate away from the handle is fixedly connected to a threaded column, both ends of the threaded column are rotatably connected to the inner wall of the shell, the outer wall of the threaded column is threadedly connected to a vertical plate, the inner wall of the vertical plate is slidably clamped with a sliding column, both ends of the sliding column are fixedly connected to the inner wall of the shell, the top of the vertical plate is fixedly connected to a curved plate, the outer wall of the curved plate is fixedly connected to an electric telescopic rod, and the outer wall of the pressure plate is fixedly connected to the output end of the electric telescopic rod.

[0009] Preferably, a pointer is fixedly connected to the outer wall of the curved plate, and a scale is fixedly connected to the surface of the workbench.

[0010] Preferably, the output end of the hydraulic cylinder is fixedly connected to a mounting plate.

[0011] Preferably, the outer wall of the punching needle is fixedly connected to a connecting plate, the inner wall of the connecting plate is provided with a first threaded hole, the outer wall of the connecting plate is plugged with a groove, the groove is provided on the inner wall of the mounting plate, the inner wall of the mounting plate is provided with a second threaded hole, and the inner walls of the first threaded hole and the second threaded hole are respectively threadedly connected with bolts.

[0012] Preferably, a collecting tank is provided below the workbench.

[0013] Preferably, a sliding block is fixedly connected to the surface of the collecting trough, and a sliding groove is slidably engaged on the outer wall of the sliding block, and the sliding groove is opened on the inner wall of the workbench.

[0014] The beneficial effects of the utility model are:

[0015] 1. The handle, connecting plate, threaded column, vertical plate, sliding column, curved plate, electric telescopic rod, pressing plate, pointer and scale are provided to adjust the position of the pressing plates on both sides, so that plastic bags of different widths can be fixed and perforated. This solves the problem that the existing perforating device can only fix and perforate plastic bags of the same width due to the fixed distance between the holding components on both sides, thus reducing the working range of the existing perforating device.

[0016] 2. By setting the connecting plate, groove, bolt, first threaded hole and second threaded hole, the punching needle can be replaced with punching needles of different thicknesses, which solves the problem that the punching needle is fixed on the cylinder, resulting in only holes of the same thickness being able to be punched into the plastic bag.
