Description

Coiled material cutting machine mechanism that stretches out Technical Field The utility model belongs to the technical field of paper bag machines, and particularly relates to a stretching mechanism of a coiled material splitting machine. Background In carrying out the utility model, the inventors have found that the prior art has at least the following problems: in the processing process of the paper bag machine, paper serving as a raw material needs to be cut and conveyed from a paper roll, and in the conventional technology, the paper is easy to wrinkle in the conveying process, so that the subsequent paper bags are formed poorly, and waste products are caused. CN 104260417B-paper bag machine and paper roll over last mouth device, disclose a paper bag machine and paper roll over last mouth device, wherein paper roll over last mouth device includes supporting component and rolls over last mouth subassembly, supporting component includes the bracing piece, cross cardboard and paper cushion, the bracing piece upper surface is equipped with and crosses the cardboard, the outer end of crossing the cardboard is protruding in the lateral surface of bracing piece, the trailing flank of paper cushion closely laminates with bracing piece and the inner terminal surface of crossing the cardboard, paper cushion upper surface is downhill slope form, roll over last mouth subassembly and include baffle and curved piece, the baffle is fixed in the upper end of baffle dead lever, also unable solution above-mentioned technical problem. Disclosure of utility model The utility model aims to solve the technical problem of providing a stretching mechanism of a coiled material splitting machine, which can enable paper to be applied with stretching tension to two sides in the advancing process, so that the paper can be stretched and pulled by stretching, and the paper can be free of wrinkles. In order to solve the technical problems, the utility model adopts the technical scheme that the stretching mechanism of the coiled material splitting machine comprises: A frame; The stretching roller and the traction roller are arranged on the frame and can be matched with the machine frame to convey paper; The stretching roller is provided with spiral notches extending from the vicinity of the middle to two sides, and the spiral notches on two sides of the stretching roller are opposite in rotation direction. The stretching roller is movably mounted on the frame through a pressing mechanism. The compressing mechanism comprises a swinging block, the stretching roller is rotatably arranged near the middle of the swinging block, the first end of the swinging block is rotatably arranged on the frame, and the second end of the swinging block is provided with a compressing power device. The compressing power device is a compressing cylinder, the compressing cylinder is arranged on the frame, and a compression rod for compressing the second end of the swing block is arranged on a piston rod of the compressing cylinder. The pressing mechanism further comprises a jacking mechanism, the jacking mechanism comprises a supporting block, the supporting block is installed on the frame, a supporting spring is arranged on the supporting block, and the supporting spring is in contact with the second end of the swinging block. The support spring is positioned below the second end of the swinging block, and the compression bar is positioned above the second end of the swinging block. The traction roller is rotatably arranged on the frame and is connected with the power device. One of the above technical solutions has the following advantages or beneficial effects, and can enable the paper to be applied with tension stretching towards two sides in the advancing process, so that the paper can be pulled through stretching, and the paper can be free of wrinkles.
