Description

Technical Field

[0001] This utility model relates to the field of tension adjustment technology for slitting machines, specifically to a tension adjustment mechanism for an inner lining paper slitting machine. Background Technology

[0002] Packaging liner paper is used inside packaging boxes, serving both sealing and wrapping functions, as well as decorative purposes. Liner paper may or may not have an outer metal foil surface, and the merchant's promotional logo is printed on its surface. Because liner paper is sold inside the packaging box along with the product, it is part of the product and represents its quality; therefore, the quality requirements for liner paper are high. It should be flat, intact, and undamaged. A paper cutter should be used to cut the liner paper to the required size.

[0003] For example, Chinese patent application No. 202421584616.3 discloses a tension adjustment mechanism for an inner liner paper slitting machine, including a worktable. A support column is fixedly connected to the top of the worktable, a lifting assembly is fixedly connected to the top of the support column, a slitting blade is fixedly connected to the bottom of the lifting assembly, an electric cylinder is fixedly connected to the left side of the lifting assembly, and a support plate is fixedly connected to the output end of the electric cylinder. In this invention, the operator can slide a slider from left to right into a limiting frame, thereby sliding a pressure spring between a movable plate and a support plate. Then, the operator activates the electric cylinder to extend. In this technical solution, the extension amount of the electric cylinder does not need to be adjusted. The extension of the electric cylinder causes the support plate and the movable plate to move downwards. When the movable plate contacts the stacked inner liner paper, the support plate continues to move downwards, thereby compressing the pressure spring. The pressure spring exerts downward pressure on the movable plate. The operator can adjust the tension of the movable plate on the stacked inner liner paper by replacing the pressure spring. This device has the advantage of being easy to adjust.

[0004] However, the following problems still exist in this technical solution: the tension is adjusted by a compression spring. The spring, which is in a compressed state for a long time, will experience metal fatigue, which will cause its elastic coefficient to change. This means that even if the adjustment position remains unchanged, the actual tension provided will gradually decrease over time. Utility Model Content

[0018] like Figure 4As shown, the conveying mechanism 4 includes a fixed frame 401 on the top of the workbench 1. The fixed frame 401 has second support plates 402 on both sides. Each second support plate 402 has a first conveying roller 403 movably connected to it through a bearing. The top of the second support plate 402 has a third support plate 404. The third support plate 404 has a second conveying roller 405 movably connected to it through a bearing. The top of the third support plate 404 has two first electric push rods 406 fixedly installed. The top of the first electric push rods 406 passes through the fixed frame 401 and extends out of the top of the fixed frame 401. The inner liner paper is pulled to the top of the two first conveyor rollers 403, and then the first electric push rod 406 is opened. The first electric push rod 406 can drive the second conveyor roller 405 to move downward, moving the second conveyor roller 405 to the top of the inner liner paper. The inner liner paper is conveyed by the first conveyor rollers 403 and the second conveyor roller 405. By controlling the distance between the second conveyor roller 405 and the first conveyor roller 403, inner liner paper of different thicknesses can be conveyed, improving practicality.

[0019] like Figure 5 As shown, the slitting mechanism 5 includes a mounting frame 501 on the top of the workbench 1. Two second electric push rods 507 are provided through the mounting frame 501.

When it is found that the tension of the inner lining paper is too tight, the support roller 302 needs to move downward to loosen the inner lining paper. When it is found that the inner lining paper is too loose, the support roller 302 needs to rise a certain distance to tighten the inner lining paper. The tensioning mechanism 3 can adjust the tension of the inner lining paper and improve the efficiency of inner lining paper cutting.
