Description

TECHNICAL FIELD

[0001] The utility model relates to rewinding machine loading and unloading raw material technical field especially a kind of quick loading and unloading device for rewinding machine. BACKGROUND

[0002] Rewinding machine is a kind of equipment for re-winding paper, film, tape and other roll materials, which mainly rotates the reel shaft through motor drive. When the initial roll material (such as large roll paper) of roll material is placed on the unwinding device, the material will be pulled by the traction mechanism, so that it is gradually unfolded and passes through a series of guide rollers. These guide rollers can ensure that the material remains flat and correct during transmission. Then, the material is wound onto a new reel, and the tension control system is used to ensure uniform tension of the material during winding, so that the finished product after winding is compact and neat. For example, in the paper industry, paper is drawn from the original paper roll and rewound by the rewinding machine to form a paper roll with better size and quality for subsequent processing or sales. Large roll paper produced by paper machines is cut and rewound to produce small roll paper of different specifications (such as different widths and lengths) to meet the needs of different users (such as printing plants, toilet paper processing plants, etc.). Plastic film (such as polyethylene film, polypropylene film, etc.) is rewound for packaging, agricultural covering, etc. In the packaging field, the rewound film can better adapt to the requirements of packaging equipment, ensuring the flatness and uniform tension of the tape or film during winding, thereby ensuring the quality of the product. Rewinding machines are used in the production process of products such as audio tapes, film, etc. There are toilet paper rewinding machines, industrial paper rewinding machines, film rewinding machines, etc. Toilet paper rewinding machines are mainly used for toilet paper processing and usually have some special functions such as embossing, punching, etc. Industrial paper rewinding machines focus on rewinding industrial paper with high strength and precision requirements.

[0003] In the prior art, the loading and unloading of paper rolls or other roll materials is a frequent and important operation step during the use of the rewinding machine, which usually relies on manual handling to send the raw materials into the rewinding machine.
