Description

Technical Field

[0001] This utility model relates to the field of heat shrink film processing technology, and in particular to a shrink packaging machine for processing heat shrink film. Background Technology

[0002] Heat shrink film, also known as shrink film, is used for the transportation and sale of various products. Its main function is to stabilize, cover and protect the products. It has high puncture resistance, good shrinkage and a certain shrinkage stress.

[0003] Existing shrink packaging machines lack adjustable guiding devices when conveying heat shrink film, making it difficult to meet the conveying needs of heat shrink film of different sizes. This can easily lead to film misalignment and wrinkles, affecting the quality of subsequent processing. Furthermore, similar equipment typically uses a fixed-spacing guiding structure, which lacks sufficient adjustment flexibility. Utility Model Content

[0006] Preferably, the adjustable limiting guide device includes a support frame fixedly installed between the two surfaces of the workbench. The inner wall surfaces of the vertical ends of the two sides of the support frame are each fixedly installed with a sleeve and a sliding top rod inside the sleeve. A limiting frame is fixedly installed at the end of the top rod away from the sleeve.

[0007] Preferably, the adjustable limiting guide device further includes vertical grooves formed on the inner wall surface of the vertical ends on both sides of the support frame, and a horizontal bar is slidably connected between the two vertical grooves. The horizontal bar and the limiting frame are hinged together by a hinge plate.

[0008] Preferably, the adjustable limiting guide device further includes a cylinder fixedly installed on the top surface of the support frame, the cylinder driving the horizontal bar to move inside the vertical groove.

[0009] The effect achieved by the above components is that the two limiting frames can move away from or towards each other, thereby using the two limiting frames to position and guide heat shrink films of different sizes, thereby reducing the possibility of the heat shrink film shifting during transmission and thus reducing the subsequent processing quality of the heat shrink film.

[0010] Preferably, the surface of the limiting frame is provided with a reinforcing device for reinforcing and guiding the heat shrinkable film, the reinforcing device comprises a fixed plate fixedly installed on the surface of the limiting frame, a vertical rod is fixedly installed on the top surface of the limiting frame, and a sliding plate is matched with the outer wall of the vertical rod to slide, a short rod is fixedly installed on the bottom surface of the sliding plate, and a moving plate is fixedly installed on the end of the short rod away from the sliding plate.

[0011] Preferably, the surfaces of the fixed plate and the moving plate are distributed with a plurality of U-shaped rods, and the outer wall surfaces of the plurality of U-shaped rods are rotatably connected with guide rollers.

[0012] Preferably, the reinforcing device further comprises a U-shaped frame fixedly installed on the side surface of the limiting frame and an electric telescopic rod matched and assembled on the bottom surface of the top horizontal end of the U-shaped frame, and the output end of the electric telescopic rod is fixedly connected with the moving plate.

[0013] The above components achieve the effects that the sliding plate, the vertical rod and the short rod enable the moving plate to move, the guide rollers enable the heat shrinkable film to be more smoothly guided and conveyed, and the electric telescopic rod enables the moving plate to move.

[0014] Compared with the prior art, the advantages and positive effects of the utility model lie in that:

[0015] In the utility model, the two limiting frames can move away from or close to each other, so that the two limiting frames are used for positioning and guiding the heat shrinkable film of different sizes, thereby reducing the deviation of the heat shrinkable film during transmission to a certain extent and reducing the quality of subsequent processing of the heat shrinkable film.
