[0011] As a preferred technical solution of the present invention, the driving mechanism further includes a low-speed motor, and an output end of the low-speed motor is drivingly connected to one end of the shaft.

[0012] As a preferred technical solution of the present invention, the clamping disk includes a disk frame, a threaded hole is opened on one side of the disk frame, and a lead screw is connected to the internal thread of the threaded hole.

[0016] In another aspect, the present invention provides a method for using a burr removal device for rubber products, comprising the following steps:

[0017] Step 1: The four positioning holes on the rubber piece are placed in the clamping grooves in the clamping plate respectively, and the bottom end of the pressing block is extended to the inside of the positioning holes by the elastic action of the compression spring on the pressing block, thereby fixing the rubber piece;

[0018] Step 2: Start the servo motor so that the output end of the servo motor drives the lead screw to rotate, causing the disc rack to roll on the top of the base through the pulley, thereby realizing horizontal movement until the annular product on the rubber part moves to the area where the hair removal needles are located, so that one row of the annular products overlaps with one row of needle bodies;

[0022] Through the power output of the driving mechanism, the pressing component drives the deburring needle to perform rising and falling movements, and cooperates with the clamping plate to drive the rubber part to move horizontally at a uniform speed, thereby causing the annular products distributed side by side to be displaced to the bottom of the needle body, and through the inclined welding of the first oblique needle and the second oblique needle, the needle body drives the first oblique needle and the second oblique needle to move in turn during the lifting process, wherein the first oblique needle removes the burrs at the center of the annular product 102, and the second oblique needle removes the burrs at the edge of the annular product. Through such reciprocating mechanical movements, the burrs of large quantities of rubber products can be removed efficiently and accurately. BRIEF DESCRIPTION OF THE DRAWINGS
