Tabletting, film laminating and knurling combined device for automobile body damping and vibration attenuation material

Abstract

The invention relates to a tabletting, film laminating and knurling combined device for an automobile body damping and vibration attenuation material. The device comprises a tabletting machine, an outlet of the tabletting machine is provided with a plastic conveyor belt, and a spraying cooling water pipeline is disposed above the plastic conveyor belt, the tail end of the conveyor belt is provided with a film laminating apparatus, and a knurling apparatus is disposed behind the film laminating apparatus. According to the invention, combined tabletting, film laminating and knurling are carried out for pipelined molding of the automobile body damping and vibration attenuation material, the combined device is convenient for production, and improves the work efficiency. Each apparatus achieves independent motor control or linkage control, and the roller motion frequency can be adjusted at any time.

Description

technical field [0001] The invention relates to the field of composite material preparation, especially one Disclosed is a sheet-coated knurling assembly device for damping and vibration-absorbing materials used for automobile bodies. Background technique [0002] The damping and vibration-absorbing material for automobile body is a hot-melt composite sheet that is blended and formed by multi-components. It can be made into different shapes and thicknesses according to needs, and laid on the body. [0003] As the asphalt-based damping sheets are currently dominated by asphalt, asphalt is brittle in winter and sticky in summer, the damping sheets are stacked for a long time without isolation means, and the temperature rises in summer. In order to prevent the damping sheet from deforming and bulging after baking, knurling treatment is carried out on the bonding surface of the damping sheet and the body, so that the internal gas can be discharged along the patterned track, and...

AI Technical Summary

Problems solved by technology

[0004] The current production method can not realize the coating knurling at the same time. At present, the conveyor belt is a cooling steel belt, and the temperature is lowered at the same time as the transmission. The coating roller is directly placed on the front end of the steel belt conveyor belt to coat the surface of the damping sheet. A knurling device is placed at the front end of the blanking conveyor belt. When the film is conveyed to the knurling device, the film has become cold and cannot be knurled.
