TH10042A - A machine for producing spiral pipes - Google Patents

Abstract

One method used to produce helical tubes involves spraying molten thermoplastic resin into a tube-shaped mold to achieve the desired diameter and wall thickness. The molten, hollow or solid ribbed portion of the sprayed material is then rolled and molded using a rotating nozzle at the outside of the sprayed tube, adjusting the speed to create a hollow or solid helical assembly. A machine used to produce helical tubes consists of a rotating body mounted on a frame with bearings around the outside of the spray nozzle end. This nozzle has a hollow inner and outer channel for spraying the thermoplastic resin into the tube-shaped mold, and a rotating cylindrical socket is positioned at the end of the nozzle to spray the hollow ribbed portion. This cylindrical socket is positioned at the end of the rotating body, and the outer surface of the sprayed tube is molded and molded. Immediately after being sprayed by the extrusion die, it will be opposite the end port of the die.

1. A ready-made machine for producing plastic pipes. With a curled ridge Is an outer spiral consisting of A flue socket formed from an inner tube-shaped assembly and an outer tube-shaped assembly forming a flow channel. The first pipe is formed during that for synthetic resin materials. Thermoplastic And a nozzle for spraying a nozzle for spraying One head for forming plastic pipes A pipe-shaped frame located around the outer pipe-shaped socket assembly. To form a shaped flow channel The second tube for thermoplastic synthetic resin material. While called Pipe-shaped frame and that is higher than the outer tube-shaped socket assembly It has a common axis called a channel. 1st pipe flow A rotating body that is positioned around the aforementioned tubular frame. The bearing device is placed between the so-called rotatable body and the so-called tubular frame to allow the body to rotate. Can be rotated around the frame, and the pipe-shaped socket assembly connected to the rotating body as Said to spray thermoplastic synthetic resin material out of place. This is called the second pipe-shaped flow channel onto the outer surface of the pipe. Plastic that has been sprayed from the so-called Nozzle for spraying And causing the ridge to form a spiral up by the rotation of the body. Such a spin 2.
