Spraying box for polyolefin small-caliber pipe production line

Abstract

The invention belongs to the technical field of polyolefin small-caliber pipe production, and particularly relates to a spraying box for a polyolefin small-caliber pipe production line, which comprises a cylinder, a pipe size adjusting component is mounted on the outer side of the cylinder, a first hanging bracket is arranged below the cylinder, and a generator is fixed at the front end of the first hanging bracket through a bolt; an automatic separation assembly is fixedly connected to an output shaft of the power generator, a lap joint plate is rotatably installed at the tail end of the automatic separation assembly and fixedly installed on the surface of the cylinder, a material arranging assembly is installed on the outer side of the front end of the automatic separation assembly, and a conveying line is arranged below the material arranging assembly. A multi-channel cooling device is mounted on the periphery of the interior of the cylinder, and a spraying cylinder is arranged in the middle of the interior of the cylinder; the spraying box can adapt to pipes of different sizes during use, cooling water flow can be used for driving the material arranging assembly to work, the automatic material arranging function is achieved, and the defect that an existing pipe production line is single in function is overcome.

Description

technical field [0001] The invention relates to the technical field of polyolefin small-diameter pipe production, in particular to a spray box for a polyolefin small-diameter pipe production line. Background technique [0002] Polyolefin pipes have the advantages of strong corrosion resistance and high temperature resistance. The pipes are produced by extrusion molding and blow molding. During the production process, cooling equipment is needed to cool the extruded pipes. The spray box is one of them. A cooling device, the existing spray box for polyolefin small-diameter pipeline production line also has some defects in use. [0003] For example, a plastic pipe production line in the publication number CN201711291710.4 adopts raw material drying equipment, metering and weighing equipment, hot-melt extrusion molding equipment, sizing cooling equipment, ultrasonic thickness measuring equipment, cooling equipment, marking equipment, traction and collecting equipment in sequence...

AI Technical Summary

Problems solved by technology

[0003] For example, a plastic pipe production line in the publication number CN201711291710.4 adopts raw material drying equipment, metering and weighing equipment, hot-melt extrusion molding equipment, sizing cooling equipment, ultrasonic thickness measuring equipment, cooling equipment, marking equipment, traction and collecting equipment in sequence. Rolling equipment and cutting equipment, when using the above-mentioned production line to produce plastic pipes, it has the advantages of high production efficiency and low production cost, and the quality of the pipes produced at the same time is high; in the process of cooling the pipes, multiple small-diameter polyolefin pipes cannot be processed at the same time For cooling work, the production efficiency is low, and it cannot be adapted to the use of pipes of different sizes, and it cannot use the cooled water flow drive device to automatically arrange materials. The use method is relatively single, and it is difficult to use in a variety of ways
