Constant-pressure surface coiling device

Abstract

The invention provides a constant-pressure surface coiling device. The constant-pressure surface coiling device comprises a rack, a coiling wheel is arranged on the rack, a core coiling pipe is arranged above the coiling wheel, sliding seats are arranged at the two ends of the core coiling pipe and connected with a lifting chain, the tail end of the chain is connected with an air cylinder, and the air cylinder stretches out and draws back to drive the chain to drive the core coiling pipe on the sliding seats to ascend and descend. According to the scheme, the friction force between the material coil and the coiling wheel is kept constant in the coiling process, the tightness of the material coil from inside to outside is kept consistent, and the percent of pass and the quality of finished products are improved.

Description

technical field [0001] The invention relates to a coiling device in the production of automobile leather, in particular to a constant pressure coiling device for surface coiling. Background technique [0002] In the current technology, the surface coiling method is that the core tube is placed on the take-up wheel, and the friction coiling is carried out by relying on the friction force between it and the take-up wheel and the rotation speed of the core tube, but when the material roll becomes larger and larger, its Its own weight also increases accordingly. When the friction coiling is still used, the burden on the coiling wheel will be increased. There will often be problems of slipping and motor tripping, and the tightness of the coil from the inside to the outside is also different. It is not conducive to production, so the diameter of the material roll has been limited in production, and the production of large roll products cannot be done. Contents of the invention ...
