A pvc pipe manufacturing unit

Abstract

The invention provides a novel PVC (Polyvinyl Chloride) pipe manufacturing unit, belonging to the field of PVC pipe manufacturing equipment. The novel PVC pipe manufacturing unit comprises a pipe discharge device, wherein the pipe discharge device comprises at least two hanging racks, a conveying device and a plurality of hanging brackets; the upper end of each hanging rack is slidably connected onto a first cable rail; each first cable rail is connected with a first lifting device; the conveying device is provided with a conveying guide rail and a conveying mechanism; the hanging racks and the hanging brackets are separately arranged on positions close to two ends of the conveying guide rail; the upper end of each hanging bracket is slidably connected onto a second cable rail; the second cable rail is connected with a second lifting device; and the upper end of each hanging bracket is provided with a control mechanism. By adopting the novel PVC pipe manufacturing unit, an extrusion-moulded PVC pipe can be drawn, conveyed and placed; a longer PVC pipe can be drawn in a section-wise cyclic manner; the PVC pipe is prevented from being drawn in an integral manner, so that the traction is more labor-saving; the PVC pipe is prevented from being bent during placement; and the automation degree is high, and the pipe discharge efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of PVC pipe manufacturing equipment, in particular to a PVC pipe manufacturing unit. Background technique [0002] The PVC pipe manufacturing unit is a commonly used automatic production line for PVC pipes. It usually includes a feeding device, a heating and melting device, a forming system, a pipe cutting device, and a pipe outlet device connected in series. The entire PVC pipe production process is generally composed of the feeding device. Lift the plastic raw material and pass it into the heating and melting device, heat the raw material through the heating and melting device to make the raw material into a molten state, then integrate the molten raw material into the molding system for extrusion molding and cooling to obtain a PVC pipe, which is cut by the pipe cutting device , Finally, the PVC pipe is exported and stored through the pipe outlet device. [0003] When the existing PVC pipe manufacturing unit produ...

Problems solved by technology

[0003] When the existing PVC pipe manufacturing unit produces longer PVC pipes, when the pipe outlet device pulls the PVC pipe to the storage device, the traction force required to drag the longer PVC pipe is relatively large, which consumes a lot of electric energy, and the storage The height of the device is usually fixed, and the pipe delivery device is likely to cause the PVC pipe to bend during the process of pulling the PVC pipe to the storage device, which affects the manufacturing accuracy of the PVC pipe product
