Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities production, in particular to a paper towel mid-feeding and positioning device. Background Art

[0002] The production process of paper towels requires multiple processes such as slicing, stacking, compression, sub-packaging, material sorting, and final packaging. Each process determines the production efficiency of paper towels. After stacking, existing paper towels usually need to be placed in packaging bags before proceeding to subsequent processes.

[0003] For example, patent number CN221341299U discloses a centrally conveyed and positioned device for paper towels, comprising: two symmetrically arranged side mounting plates; a first rotating shaft mounted between the two side mounting plates, a first belt roller mounted on the first rotating shaft; and a second rotating shaft rotatably mounted between the two side mounting plates, a second belt roller fixed on the second rotating shaft. The aforementioned document still has shortcomings. During use, the positioning member effectively prevents the paper towels from shifting during the swing-side ironing and sealing process, while eliminating the problems of the paper towels tipping over, deforming, or loosening, thereby effectively improving the swing ironing effect. The receiving plate effectively supports the conveying surface of the conveyor belt, keeping the conveying surface of the conveyor belt horizontal. However, the positioning of the paper towels in the aforementioned document is achieved through a positioning frame, which can only position paper towels of a fixed size. In actual use, it is not convenient to position paper towels of different sizes. In addition, the toothed belt is prone to slack during transmission. The receiving plate in the aforementioned document prevents the toothed belt from being too tight. When the toothed belt slackens, the toothed belt cannot be tightened, thereby affecting the conveying of the paper towels. Utility Model Content

When the second toothed pulley 12 moves to the left, the toothed belt 5 is tightened. When the spring 406 cannot realize the bearing seat 405 sliding to the left, the second rotating wheel 402 is rotated, and the second rotating wheel 402 drives the second screw 401 to rotate. The second screw 401 drives the threaded cylinder 403 to slide to the left, and the threaded cylinder 403 squeezes the spring 406 to compress the spring 406, so that the spring 406 has the force to drive the bearing seat 405 to slide to the left under the elastic action. The tightening mechanism 4 can drive the second toothed pulley 12 to move to the left to tighten the toothed belt 5. When the toothed belt 5 is loose, the toothed belt 5 can be tightened, thereby not affecting the transportation of paper towels.
