AI Technical Summary

Technical Problem

The existing rubber extrusion and cutting equipment has problems such as easy blockage of the runner, inconvenient rubber forming, and incompatibility of extruder and cutting machine, resulting in inconsistent weight of the rubber after cutting.

Method used

An integrated automatic cutting rubber extrusion preforming device is designed, using a trumpet-shaped extrusion head design with a flat sheet flow channel. Combined with an automatic cutting device, including a driving cylinder, a top plate, a cutter and a guide block, to form an integrated structure to achieve automatic cutting.

Benefits of technology

The unique extrusion head runner design reduces rubber buildup and internal stress, ensuring consistent weight after cutting and maintaining temperature and fluidity. The device is removable, making it easier to replace the extrusion head or nozzle to suit different product types.

Abstract

The invention provides an integrated automatic cutting rubber extrusion pre-forming device. The integrated automatic cutting rubber extrusion pre-forming device comprises an extrusion head and an automatic cutting device, the extrusion head comprises an extrusion head body and a glue outlet nozzle; the automatic cutting device comprises a driving air cylinder, a top plate, a cutter and guide blocks, the air cylinder is installed on the top plate, the cutter is connected below the air cylinder, the cutter is arranged above an outlet of an extrusion head runner, and the cutter is guided and restrained by the copper guide blocks on the two sides; the extrusion head and the automatic cutting device are connected through a connecting part to form an integrated structure, so that the automatic cutting device can cut a rubber product which is just extruded from the extrusion head. The unique design of the extrusion head runner can reduce the impact of the extruder on the extrusion head, reduce the possibility of accumulation of rubber in the runner and well eliminate the internal stress of a rubber product, the cutter is directly attached to the wall of the extrusion opening of the extrusion head, it is guaranteed that the front section of rubber is still in the extrusion opening after cutting, and the temperature and fluidity are kept.
