Detailed Description

The invention will be further explained with reference to the drawings.

This novel extrusion tread defective products automatic pickup attachment that relates to is at the autofilter device that current extrusion production line (including extrusion equipment, interlocking line, metal detection device, cutting device, weight detection device, beat mark device) increases, and it has solved the artifical problem of choosing and omitting of tread defective products.

As shown in fig. 7, the extruded tire tread is conveyed through a linkage line, the cut single tire tread passes through a metal detection device and a weight detection device at intervals in sequence, detection information is matched with a standard range arranged in the device, when the tire tread is detected to have metal impurities in rubber or defective products with weight exceeding the standard range, the metal detection device and the weight detection device send marking instructions, the marking device can fall on the surface of the tire tread defective product during conveying to mark teeth marks, the defective products are identified, meanwhile, position signals of the defective products are sent to the center of a control system and are transmitted to an automatic picking device for extruding the tire tread defective products, when the defective products reach the automatic picking device, a transmission guide roller assembly stops moving, a turnover assembly acts, a turnover cylinder drives a pull rod to turn over a turnover beam for a certain angle, the defective product tire tread above the turnover beam slides along the turnover beam, and then, the overturning cylinder resets, the overturning cross beam restores to the original position, the conveying guide roller assembly continues to convey forwards, and the automatic picking action of the defective tire tread is completed.

The signal transmission and system control processes involved in the above processes are prior art, and are not the design key points of the technical scheme, and are not described herein again.
