Abstract

The invention discloses a device for pricking bubbles in a semi-finished rubber sheet of a rubber product. The device for pricking the bubbles in the semi-finished rubber sheet of the rubber product comprises a standard part pneumatic cylinder (1), a cylinder fixing plate (2), a cylinder joint connecting part (3), a steel needle fixing plate (4), a steel needle (5), four connecting rods (6), a rubber sheet falling plate (7) and a platform (8). The device is mainly characterized in that the cylinder joint connecting part (3) and the steel needle fixing plate (4) are fixed through bolts and clamp the steel needle (5), the cylinder joint connecting part (3) is fixed on the standard part pneumatic cylinder (1), the standard part pneumatic cylinder (1) drives the steel needle (5) to do reciprocating motion, and when the steel needle (5) is lifted after pricking the rubber sheet, the rubber sheet falling plate (7) can allow the rubber sheet to automatically fall from the steel needle (5). The device has good practicability and can efficiently prick the bubbles in the rubber sheet, the rubber sheet can be automatically separated from the steel needle, and the device can greatly improve the qualified rate of rubber products and reduce generation of cavitation.

Description

technical field [0001] The invention relates to a device for piercing the air bubbles in the semi-finished film of rubber products, which can pierce the air bubbles in the semi-finished film of rubber products, and automatically separate the film from the steel needle, so that the film can be easily removed from the platform. Reduce the occurrence of air pockets in the production process of rubber products, and improve the qualified rate of rubber products. Background technique [0002] When preparing the film semi-finished product in the production process of rubber products, there will inevitably be air bubbles in the film semi-finished product. When producing rubber products with semi-finished products with air bubbles, there is a certain probability that the rubber products will have air pocket defects, resulting in the generation of substandard products. How to remove the air bubbles like this, the product that reduces the air pocket defect of rubber product has just b...
