Automatic fixed-length cutting machine for PVC pipe

Abstract

The invention provides an automatic fixed-length cutting machine for a PVC pipe. The automatic fixed-length cutting machine comprises a lap joint sleeve frame, a supporting rod, a moving device, a distance adjusting device, an opening grinding device, a limiting device, a cutting device and a material guide pipe. The automatic fixed-length cutting machine solves the problems that in the fixed-length cutting process of the PVC pipe, the cutting length of the PVC pipe is not uniform, so that the length of the PVC pipe is not uniform in the installation and using process, the notch quality between pipes is difficult to guarantee, installation and using of the pipes are affected, notches of the pipes are difficult to keep flat in the pipe cutting process of an existing cutting device, and therefore the sealing performance of the pipes after installation and connection is affected.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to an automatic fixed-length cutting machine for PVC pipes. Background technique [0002] PVC is the abbreviation of (Polyvinylchlorid), the main component is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness and ductility. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. PVC pipe (divided into pvc-U pipe, pvc-M pipe and pvc-O pipe) rigid polyvinyl chloride pipe is extruded by hot pressing method after combining polyvinyl chloride resin with stabilizer, lubricant, etc. The first plastic pipe to be developed and applied. [0003] The current pvc pipe is usually cut according to the fixed length during use, but the pvc pipe mainly has the following problems in the process of cutting the pvc pipe: the cutting length ...

AI Technical Summary

Problems solved by technology

[0003] The current pvc pipe is usually cut according to the fixed length during use, but the pvc pipe mainly has the following problems in the process of cutting the pvc pipe: the cutting length of the pvc pipe is not uniform, resulting in the length of the pvc pipe during installation and use. It is difficult to ensure the quality of the incision between the pipes due to unevenness, which will affect the installation and use of the pipes, and it is difficult to keep the incision of the pipes flat when the existing cutting device cuts the pipes, thus affecting the sealing of the pipes after installation and connection
