Punching device of rubber belt

Abstract

The invention discloses a punching device of a rubber belt. The punching device comprises a frame and a workbench and a controller arranged on the frame, the workbench is provided with a belt rotationmechanism and a belt punching mechanism, the belt rotation mechanism comprises a driving shaft which is driven by a servo motor A to rotate and a tensile shaft which is arranged on a horizontal guiderail and driven by a servo motor B to move along the horizontal guide rail, the belt punching mechanism comprises a recess die, a deflector, a punch die, a punch die fixed plate and a linear servo motor, the frame is further provided with an induction grating for safety protection, and the servo motor A, the servo motor B, the linear servo motor and the induction grating are all in communicationconnection with the controller. The servo motors replace cylinders and hydraulic cylinders, the stroke is more stable, control is more convenient, the punching precision and efficiency are higher, andnoise and the cost are lower.

Description

Technical field [0001] The invention relates to a rubber belt punching device, which belongs to the mechanical field. Background technique [0002] The conveying belt is an important part of the printer. It is mainly used to convey the paper of the printer. In order to improve the conveying accuracy and conveying capacity, it is necessary to punch uniformly distributed small holes on the belt. In the prior art, the belt punching mainly includes cylinder punching and hydraulic punching. Cylinder-type punching is unstable due to the constant supply of air by the air pump, resulting in unstable die stroke, deviation of the punching size, and a long single-product punching time. Single-piece punching requires about 90S, and the punching force is not enough. The burrs around the punching hole become larger, resulting in low production efficiency and poor pass rate. Although the stroke of hydraulic punching is relatively stable, it also has the defects of noise and oil leakage when u...

AI Technical Summary

Problems solved by technology

Due to the unstable air pressure caused by the non-stop air supply of the air pump, the cylinder type punching leads to unstable punching stroke and deviation in punching size. The burrs around the punching hole become larger, which makes the product production efficiency low and the pass rate poor

Although the stroke of hydraulic punching is relatively stable, it also has the disadvantages of noise and oil leakage after long-term use, and the disadvantages of high equipment cost
