Description

Technical Field

[0001] The utility model belongs to the technical field of spring glue spraying, in particular to a spring glue spraying device. Background Art

[0002] At present, flocking springs have a low friction coefficient and are widely used in electric tailgates. After the spring is flocked, its friction mode can be changed from direct friction between metal and metal or plastic to friction between flock and metal or plastic, which can reduce the noise generated during friction.

[0003] The existing announcement number is CN207899626U, and the name is a Chinese utility model patent for a flocking spring production line equipment. The working process of the flocking spring production line equipment provided by the patent is as follows: the process of placing the spring vertically on the conveying chain of the flocking production line through a hook is loading, which is completed manually. The upper and lower ends of the spring are hung on the conveying chain of the production line through hooks. When the photoelectric control device detects that the spring passes, the spray gun starts to work. The glue spraying process is completed by three groups of spray guns. The spray gun is placed on the guide rail, and the guide rail is placed vertically on the ground. When the spring enters the glue spraying station, the nozzle moves up and down to cover the surface of the spring that needs to be sprayed. The spring length information fed back by the photoelectric control device is used to control the displacement position of the spray gun. The flocking spring production line equipment conveys the spring through a straight synchronous chain. The spring cannot be opened outward when spraying. When the spring is too loose, the spacing between adjacent spring coils is small, which is easy to cause obstruction during glue spraying, which is not conducive to the glue spraying operation, resulting in uneven spring glue spraying. And when the spring is sprayed with glue, the spring is always sprayed with glue on the same side, and it cannot be sprayed with glue while turning over, which will result in uneven spraying of the spring.
