Abstract

The invention discloses a device for pricking air bubbles in semi-finished rubber sheets of rubber products, which consists of a standard pneumatic cylinder (1), a cylinder fixing plate (2), an ejector plate upper fixing plate (3), a cutter (4), an outer ejector plate (5), an inner ejector plate (6), a platform (7), a standard bolt and a screw (8). The pneumatic film cutting machine is mainly characterized in that a cutter (4) is fixed on a standard part pneumatic cylinder (1), an outer ejection disc (5) and an inner ejection disc (6) are fixed with an ejection disc upper fixing plate (3) through a standard part bolt and a screw rod (8), when the standard part pneumatic cylinder (1) drives the cutter (4) to reciprocate, the positions of the outer ejection disc (5) and the inner ejection disc (6) are unchanged, and when a film is cut into a ring shape, the outer ejection disc (5) and the inner ejection disc (6) can forcibly enable the ring-shaped film to fall off from the cutter (4). The device has good practicability, and can greatly improve the preparation efficiency of the semi-finished product of the rubber product and the production efficiency.

Description

Cutting device for annular semi-finished rubber product

Technical Field

The invention relates to a cutting device for an annular semi-finished product of a rubber product, which can cut a film into an annular shape, forcibly separate the annular film from a cutter and conveniently take the film off a platform. The device can greatly improve the preparation efficiency of the semi-finished product of the rubber product and improve the production efficiency.

Background

When preparing the semi-finished product of the annular rubber sheet in the production process of the rubber product, scissors are mostly used for cutting the annular rubber sheet into rings, and the production efficiency is very low. How to rapidly prepare the annular rubber product becomes a problem to be solved urgently.

Disclosure of Invention

The technical scheme is as follows:

in order to solve the problems, the invention designs a cutting piece device for an annular semi-finished product of a rubber product. The invention aims to rapidly prepare a semi-finished product through a mechanical device and improve the production efficiency.

The standard pneumatic cylinder (1) is an SC type pneumatic cylinder standard and can reciprocate after being communicated with compressed air. The standard part bolt and the screw (8) are standard parts. The cylinder fixing plate (2), the ejection plate upper fixing plate (3), the cut-off knife (4), the outer ejection plate (5), the inner ejection plate (6) and the platform (7) can be machined and manufactured in a machining mode.

The cut-off knife (4) is fixed on the standard component pneumatic cylinder (1). The outer ejection disc (5) and the inner ejection disc (6) are fixed with the upper fixed plate (3) of the ejection disc through standard part bolts and screws (8). The ejection disc upper fixing plate (3) and the standard part pneumatic cylinder (1) are fixed on the cylinder fixing plate (2) through standard part bolts and screws (8). The cylinder fixing plate (2) is fixed on the platform (7) through a standard part bolt and a screw rod (8). When the standard part pneumatic cylinder (1) drives the cutter (4) to reciprocate, the positions of the outer ejection disc (5) and the inner ejection disc (6) are unchanged. When the film is cut into a ring shape, the outer ejection disc (5) and the inner ejection disc (6) can force the ring-shaped film to fall off from the cutter (4). The device has good practicability, and can greatly improve the preparation efficiency of the semi-finished product of the rubber product and the production efficiency.

The invention is further described below with reference to the accompanying drawings.

Detailed Description

Example (b):

the standard pneumatic cylinder (1) is an SC type pneumatic cylinder standard, can reciprocate after being communicated with compressed air, and can control the reciprocating motion of the cylinder through a five-position three-way valve.

The standard part bolt and the screw (8) are standard parts and can be fixed by using a nut.

The relative positions of the cylinder fixing plate (2), the ejection plate upper fixing plate (3), the cut-off knife (4), the outer ejection plate (5), the inner ejection plate (6) and each component of the platform (7) can be adjusted through a standard part bolt and a screw rod (8). The cylinder fixing plate (2), the ejection plate upper fixing plate (3), the cut-off knife (4), the outer ejection plate (5), the inner ejection plate (6) and the platform (7) can be machined and manufactured in a machining mode, and then all the components are fixed into a whole by using bolts and nuts according to the drawing 1. When the standard part pneumatic cylinder (1) drives the cutter (4) to reciprocate, the positions of the outer ejection disc (5) and the inner ejection disc (6) are unchanged. When the film is cut into a ring shape, the outer ejection disc (5) and the inner ejection disc (6) can force the ring-shaped film to fall off from the cutter (4). The invention has manufactured the model machine, the model machine has good running state, has greatly raised the production efficiency.

It is understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art should understand that they can make various changes, modifications, additions and substitutions within the spirit and scope of the present invention.
