TECHNICAL FIELD

[0001] The utility model relates to a kind of cleaning roll brush processing technical field, specifically to a kind of cleaning roll brush shaft injection molding device of sweeping robot processing. BACKGROUND

[0002] With the improvement of people's living standards, the style type of dust collector on market is more and more, and its performance is more and more superior. Now, the brush wheel of dust collector is mostly single wheel or double wheel, and the bristles on the wheel are generally linear or spiral, or single-piece brush formed by rubber. But whether linear or spiral bristles, they are implanted on the circumference of brush rotating shaft, so that it is necessary to open several insertion holes for inserting bristles on the circumference of brush rotating shaft, and then implant bristles into insertion holes. This way is low in efficiency, high in cost, and bristles are easy to fall off.

[0003] The patent document with publication number CN107116746A discloses an integrated brush and its injection molding mold. The injection molding mold for producing the integrated brush includes a fixed mold and a movable mold. The movable mold is located below the fixed mold. The fixed mold is installed at the bottom of the fixed template of an injection molding machine. The movable mold is installed at the upper part of the movable template of the injection molding machine. The top surface of the movable template is symmetrically provided with guide columns on both sides of the movable mold. The bottom of the movable template is connected with support columns, which are symmetrically distributed at the bottom of the movable template. The bottom end of the support column is fixedly connected with a base. The center of the base is provided with a through hole. A push shaft is sleeved in the through hole. The top of the push shaft is connected with a push plate. The top of the push plate is provided with a push rod and a push rod guide. The push rod and the push rod guide penetrate through the movable template and the movable mold. The lower surface of the fixed mold is provided with a guide groove and a split groove corresponding to the guide columns and the movable mold respectively. The connection between the fixed mold and the fixed template is provided with a pouring system. By fixing the brush wire on the brush handle injection molding device, the brush handle is formed by the injection molding process to cover the brush wire, so that the brush handle and the brush wire are integrated and firmly bonded. However, during the injection molding process, the combined brush wire is relatively soft, which is not convenient for positioning. The brush wire is easy to move during the injection molding process, and the brush wire needs to be trimmed after the injection molding is completed. When the brush wire is pre-installed in the injection molding mold, the multiple clusters of brush wire are combined to form a circular ring, and then the cleaning roll brush shaft is injection molded. The brush wire is integrally formed with the cleaning roll brush shaft. The process of combining the multiple clusters of brush wire to form a circular ring needs a long time.

[0004] In order to improve the production efficiency, the multiple clusters of brush wire are arranged horizontally after being attached to the existing brush processing technology, and then the strip-shaped part is injection molded, so that the strip-shaped part and the multiple clusters of brush wire are combined to form the brush part. The technology is relatively mature. Then the brush part is combined with the injection molding mold, and the cleaning roll brush shaft and the strip-shaped part with multiple clusters of brush wire are integrally injection molded. In this production process, the strip-shaped part is convenient for positioning, and the position of the brush wire is easy to control, so that the production efficiency can be improved and the production cost can be reduced.

[0036] The bottom plate 1 is fixed with a injection pipe 23 in communication with the outer sleeve.

[0037] The cleaning roller brush shaft injection molding device for the sweeping robot further comprises a positioning assembly.

[0038] The positioning assembly comprises a support rod 14, a core rod 18 fixed concentrically at the lower end of the support rod 14, and a pressing sleeve 15 slidingly arranged on the support rod 14 and connected with a driving assembly on the support rod 14.
