Description

Technical Field

[0001] The utility model relates to a traction device for producing wood-grained paper, belonging to the technical field of wood-grained paper. Background Art

[0002] Wood grain paper is a kind of special paper. It is usually made of wood pulp kraft paper as the base paper, and then the surface is processed by embossing, dyeing and other processes. Finally, colorful wood grain paper with different patterns is produced. Wood grain paper is used in various fields because of its high ornamental value, strong practicality and high cost performance. Especially for the packaging of various products, a traction device is needed in the production process of wood grain paper.

[0003] The patent document with the publication number CN210047146U discloses a traction device for wood-grained paper production, which belongs to the technical field of wood-grained paper production, and includes a device body, a vertical rod connected to one side of the top of the device body, and the traction device for wood-grained paper production is provided with a crossbar, a spring and a pressure plate. When the user uses the device to pull the wood-grained paper, the pressure plate can be pulled first to extend the tension spring of the pressure plate. After the spring is extended, the user can put the wood-grained paper roll on the traction roller and release the pressure plate, so that the stretched spring pulls the pressure plate to press the wood-grained paper through elastic contraction, thereby preventing the wood-grained paper from slipping off the traction roller due to the smoothness of the traction roller, thereby greatly improving the work efficiency of the user, and when the wood-grained paper is wound around the traction roller through the rotation of the traction roller, causing the wood-grained paper to gradually become thicker, the pressure plate can be squeezed to stretch the spring, so that the pressure plate is gradually increased with the thickness of the wood-grained paper, thereby pressing and fixing the wood-grained paper at all times;

[0004] The traction device in the above technical solution is not convenient for quick disassembly of the winding drum. When the surface of the winding drum is full of wood-grained paper, a new traction device needs to be replaced to rewind the wood-grained paper, which is very time-consuming and labor-intensive, increasing the use cost of the device. In addition, it is not convenient to adjust the tension of the wood-grained paper when winding it, which easily leads to the wood-grained paper not being rolled compactly enough.

[0005] Therefore, a traction device for producing wood grain paper is proposed. Utility Model Content

[0006] In view of this, the utility model provides a traction device for producing wood grain paper to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.
