Description

Technical Field

[0001] The utility model relates to the technical field of material strip reel changing and receiving, in particular to an automatic reel changing and receiving device. Background Art

[0002] The automatic reel-changing and receiving mechanism is a supporting device for winding the material strip and reel. When preparing the material strip product, the product is first formed on the hob machine and needs to be delivered to the terminal for the material rewinding operation through the material reel. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of the material strip reel-changing and receiving mechanism.

[0003] The invention patent application number CN202310489855.4 discloses an automatic roll-changing and receiving mechanism and its use method. The automatic roll-changing and receiving mechanism has the following defects when used: (1) After the loading is completed, the material is cut by a cantilevered roller cutting assembly. The cantilever installation has one side as the installation force point and the other side is suspended in the air, and the structure is not stable enough. When the material of the material strip is relatively thick, there is a situation where the material strip or the paper separator cannot be cut; (2) The material strip is currently fed by the relatively rotating lower roller and upper roller. The cutting wheel friction feeds the material, and the material is fed by friction. If the friction is insufficient, the material cannot be fed smoothly. After the previous roll is wound and cut, if the friction between the subsequent separator and the material strip is insufficient, the separator will not be transmitted, resulting in no separator between the material strips after the material is wound, resulting in adhesion, which does not meet the material winding requirements; (3) A set of pressure wheel assemblies are set to press the material in one direction. The material winding group can only perform one-way material winding, and the pressure winding device can only realize clockwise pressure winding. If the material winding roll is wound counterclockwise, the pressure wheel cannot press and wind the material.
