Production process of roller assembly

Abstract

The invention relates to a production process of a roller assembly. The production process comprises the steps that A, rollers and a circular pipe are assembled, a certain number of the rollers are arranged on the circular pipe in a penetrating mode; B, glue spraying is conducted, specifically, glue is sprayed to the side faces of the rollers through a glue spraying device; C, vulcanizing treatment is conducted, specifically, the rollers are put into a drying oven to be vulcanized; D, polyurethane is poured, specifically, the rollers are put into a mould, and the polyurethane is poured into the rollers through a pouring machine; E, splitting is conducted, specifically, the rollers are taken out from the mould after the polyurethane is solidified, and the rollers are split through a cuttingdevice; and F, assembling is conducted, specifically, the rollers, a rotating shaft and a bearing are assembled together through assembling equipment. After the scheme is adopted, the production efficiency of the roller assembly can be improved.

Description

technical field [0001] The invention relates to a production process of a roller assembly. Background technique [0002] In the elevator door equipment, a roller assembly is usually provided, and the roller assembly is installed at the bottom of the elevator door to facilitate the sliding of the elevator door. The roller assembly usually consists of a roller, a rotating shaft and a bearing. The bearing fits in the roller, and the rotating shaft fits in the bearing. An annular groove is arranged outside the roller, and polyurethane is filled in the annular groove. In the production process of the roller, it is necessary to spray glue on the surface of the roller first, put the roller into the oven for vulcanization of the glue, and then fill the annular groove with polyurethane. In the traditional production process, the surface of the rollers is usually sprayed with glue one by one by manual glue brushing, and then the rollers are vulcanized, and then the rollers are fille...

Problems solved by technology

In the traditional production process, the surface of the rollers is usually sprayed with glue one by one by manual glue brushing, and then the rollers are vulcanized, and then the rollers are filled with polyurethane, and the processing of the rollers is completed. Since the rollers cannot be processed in batches Glue spraying, vulcanization treatment and polyurethane filling, so the production efficiency of the roller is low. After the roller is completed, the roller, shaft and bearing are manually assembled to form the final roller assembly. The assembly efficiency is low. The combination of the above reasons leads to the roller assembly. The production efficiency is low, time-consuming and labor-intensive
