Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a rubber band unwinding device. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a molecular weight that is often large, greater than hundreds of thousands. Rubber is divided into natural rubber and synthetic rubber. Natural rubber is made by extracting gum from plants such as rubber trees and rubber grass. Rubber bands generally use rubber filaments as the inner core and are wrapped by fiber filaments. They are used to make elastic fabric products such as elastic bands and elastic ropes. During the use of rubber bands, they need to be wound around wire rollers for use in weaving equipment.

[0003] A rubber band unwinding device proposed in application number 201921318809.3 can move and fix the retaining ring in the axial direction on the unwinding roller by rotating the retaining ring, and can change the relative position in the axial direction between the retaining ring and the unwinding roller, thereby achieving axial limitation of rubber band rolls of different widths, so as to improve the stability of the rubber roll during unwinding, thereby improving production efficiency.

[0004] However, during use, personnel need to carry the winding roller and place it on the top of the pay-off frame. After the rubber is rolled up, the winding roller has a large mass, which requires personnel to consume a lot of physical strength to carry it. In addition, the installation efficiency of the pay-off roller will be low due to the transportation. Based on this, the utility model designs a rubber band pay-off device to solve the above problems. Utility Model Content
