Production method and device of spiral PVC (Polyvinyl Chloride) muffler tube

Abstract

The invention discloses a production method and a device of a spiral PVC (Polyvinyl Chloride) muffler tube. According to the production method, a PVC tube with inner ribs is extruded by using an extruder with grooves, and the PVC tube with the inner ribs penetrates through a vacuum water-cooling tank and then is connected with a rotating tractor. As a method that the position of a spiral machine is adjusted, the spiral machine is put into the vacuum water-cooling machine, and subsequently a rotating machine is combined with the tractor is adopted, waste tubes can be generated when the production is started, however, after solidified tube fittings are contacted with the rotating tractor, along with the conduction of torsion, the PVC tubes extruded from the extruder and provided with the ribs can be subjected to the torsion so as to form spiral patterns, and the twisted ribs can be well shaped in the gradual cooling process, so that the yield of the spiral muffler tube is ensured.

Description

technical field [0001] The invention relates to a production method and device of a PVC spiral silencer pipe, belonging to the technical field of PVC spiral silencer pipe production. Background technique [0002] With the development of the plastic industry, the scope of application of plastic pipes in the field of water supply and drainage has gradually expanded. This is due to the many characteristics of plastic pipes themselves, such as good corrosion resistance, small thermal conductivity, light weight, and convenient installation and transportation; At the same time, it is also closely related to the continuous pursuit of technological progress by plastic pipe manufacturers, thereby improving the application characteristics of plastic pipes and forming the diversity of pipes. The spiral sound-absorbing pipe is a PVC pipe with a new geometric structure developed in recent years. The structure of the PVC spiral silencer pipe is mainly to process spiral ribs on the inner ...

AI Technical Summary

Problems solved by technology

[0003] The existing method of processing PVC spiral silencer pipes is to use a grooved extrusion head to extrude a PVC pipe with ribbed strips on the inner wall, and then insert the The rib-shaped PVC pipe is fed into the rotating machine to generate torque at one end of the pipe fitting. When the pipe fitting is not finalized, it is twisted to make the rib-shaped strip form a spiral shape, and then through the vacuum water cooler and traction machine, the production of the spiral silencer pipe can be completed. , the purpose of using the existing process is to twist the PVC pipe fittings when they are not cooled and shaped, but in the process of use, it is found that there are many defective and waste products in the spiral silencer pipe produced by this method, and further improvement is needed
