Description

Liquid glue coating device

The invention relates to a coating device for sequentially screwing sequentially moving screws to adhere liquid rubber.

In the prior art, when manufacturing screws with specific leak-proof or loose-proof effects, one of the manufacturing processes is to coat the screw threads with rubbers with specific leak-proof or loose-proof effects. These rubbers have a certain consistency. When a large number of screw gluing operations are performed, in order to save costs and ensure uniform quality, the existing technology has used an automatic gluing manufacturing machine that can arrange each of the screws and then automatically move to the gluing mechanism in order to perform the gluing operation. The gluing area of the screw thread includes the gluing of the entire peripheral surface, the gluing of the semi-peripheral surface, or the gluing of a specific area, so as to achieve a set degree of tightness or bonding strength after the screws are assembled and combined.

In order to increase the production speed of such leak-proof and loose-proof screws, each of the arranged screws sequentially moves through and is positioned above the container containing the liquid glue. At this time, the liquid glue with a higher consistency in the container slightly floats above the container. Opening for the glue to pass through the screw part of the screw above the container. At this time, the thicker liquid glue will cause resistance to the screw in movement, which will cause the screw to swing or push irregularly.
