Flocking method for seal strip

Abstract

The seal strip flocking method includes a gluing pre-treatment process to paint the surface of the seal strip with gluing pens and a flocking treatment process to flock the seal strip. During the gluing pre-treatment process, the seal strip is made to rotate around the axis of the seal strip and to move axially, and at least two gluing pens are used to paint the seal strip in once step. During the flocking treatment process, the flocking job is finished in once step. In addition, during gluing, the rotation of the seal strip will not decrease the density of the painted glue.

Description

Technical field: [0001] The present invention relates to the process of coating liquid or other fluids on the surface or part of the surface of an object, especially to the post-treatment method of the coating, in particular to a surface treatment method for rubber products after gluing, in particular, a method for Flocking method for automobile weather strips. Background technique: [0002] In the prior art, a rubber sealing strip used for automobiles has multiple surfaces that need to be flocked. The method adopted is that after the molding machine on the production line extrudes the sealing strip, the first surface of the sealing strip The surface is glued, and the glue-coating equipment uses a glue-coating pen. The glue-coating pen applies glue material to the sealing strip running vertically below it, and then pulls the sealing strip into the high-voltage electrostatic flocking warehouse for the flocking treatment of the first surface. After the flocking treatment on t...

Problems solved by technology

[0003] The technical problem to be solved by this invention is: because in the prior art, a kind of rubber sealing strip that is used for automobile has multiple surfaces and needs to carry out flocking treatment, the method that adopts now is that the forming machine on the production line will seal the strip After extrusion, apply glue on the first surface of the sealing strip. The gluing equipment uses a gluing pen. The gluing pen runs vertically to the sealing strip below it to coat the glue material, and then it is pulled into the high-voltage electrostatic flocking warehouse for the second Flocking treatment on the first surface, after the flocking treatment on the first surface, turn over the sealing strip, apply glue on the remaining surface of the sealing strip to be treated, after the glue coating is completed, pull it into the high-voltage electrostatic flocking warehouse again for flocking treatment, Therefore, it is necessary to repeatedly occupy the flocking warehouse for the same sealing strip, resulting in a decrease in production efficiency on the production line. At the same time, at the intersection of the glue material on the surface of the sealing strip after multiple gluing, the fluff is easy to stick together, which makes the surface quality of the sealing strip deteriorate. Poor. In addition, before the process of repeated gluing begins, repeated traction must be carried out, and the coordinate position and parameters of the gluing pen must be adjusted. The process is cumbersome
