Auxiliary hosepipe cutting device

Abstract

The invention discloses an auxiliary hosepipe cutting device which comprises a casing, wherein a support, a positioning frame and a sleeve are sequentially fixed inside the casing; one end of the casing is sealed and provided with a hosepipe outlet, and the other end of the casing is open and connected with the front end of a hosepipe supporting seat; the support is arranged in front of the hosepipe supporting seat; the support is in a lamp holder shape, bosses formed on two sides of the support are connected with the positioning frame, and the bosses and the positioning frame form annular cracks; the bosses formed in two sides are connected with the sleeve with a circular-truncated-cone-shaped opening formed in the front end; the circular-truncated-cone-shaped opening is matched with the tail of the support, and the opening and the tail of the support form an airflow channel; through holes are formed in the middle portions of the hosepipe supporting seat, the support and the sleeve; and the centers of the through holes and the center of the hosepipe outlet are located on the same horizontal line. According to the device, an air multiplier is used for 'straightening' a hosepipe for cutting, so that the cutting length is accurate, and precise cutting of a thin walled pipe and the hosepipe can be achieved in a real sense; and production and cutting can be carried out at the same time, so that the problems of curling, contamination and the like which are caused by secondary operation are avoided.

Description

technical field [0001] The invention relates to pipe material cutting equipment in the field of extrusion, in particular to equipment suitable for precision small-sized hose cutting. Background technique [0002] A kind of traction cutting equipment is commonly used in the field of precision extrusion. The equipment is suitable for hard pipes of different sizes (above 50D) and has a good cutting effect. But for materials with very low hardness, such as soft PVC, soft TPU materials, Pebax2533, Pebax3533 and other soft materials, this effect is lost. This is mainly due to the fact that the cutting knives of the conventional traction cutting equipment are placed after the traction equipment. However, there is a certain distance between the cutting equipment and the traction equipment (ranging from 10cm to 20cm). During the horizontal conveying process, the hose is greatly affected by its own gravity, and its axial support force is not enough to support its forward conveying. ...

Problems solved by technology

However, there is a certain distance between the cutting equipment and the traction equipment (ranging from 10cm to 20cm). During the horizontal conveying process, the hose is greatly affected by its own gravity, and its axial support force is not enough to support its forward conveying. , which eventually leads to low accuracy of cutting length, and even cutting cannot be completed

[0003] At present, for the production of this type of hose products, it is often collected and followed by cutting, that is, the method of first winding and then cutting to length. On the one hand, it adds a production process and increases the production cost; on the other hand, it is easy Causes pipe deformation or secondary pollution due to crimping operations, reducing product quality
