Cooling device for producing plastic pipe

Abstract

The invention discloses a cooling device for producing a plastic pipe. The cooling device comprises a surface box body, wherein supporting rods are fixedly arranged at four corners of the bottom end of the box body; a plurality of exhausting barrels are fixedly arranged at the top end of the box body. The cooling device for producing the plastic pipe, provided by the invention, is arranged on thenext procedure after the plastic pipe is subjected to primary cooling, so that the plastic pipe subjected to the primary cooling firstly enters the cooling device from a through hole and then passes through barrel bodies and a cylinder from the through hole in sequence to enter the next procedure; in the process, a draught fan continuously blows cold air into the box body through an air blowing pipe; in order to prevent a condition that the plastic pipe is deformed and bent when the primary cooling is not enough, the barrel bodies with four different diameters are arranged, so that one barrelbody corresponding to the diameter of the plastic pipe can be selected; when the plastic pipe enters the barrel body, the inner diameter of the barrel body is the same as the production diameter so that the plastic pipe is not bent and deformed, the aim of cooling the plastic pipe again is effectively realized and a working progress is effectively improved.

Description

technical field [0001] The invention relates to the field of plastic product production, in particular to a cooling device for plastic pipe production. Background technique [0002] At present, most of the production methods of plastic pipes are extrusion molding, and in the process of extrusion molding of plastic pipes, the newly extruded plastic pipes are in a high temperature state, and the shape is easily deformed. Therefore, the plastic pipes need to be cooled immediately . At present, after the plastic pipe is cooled once, it will directly enter the next process. However, sometimes it will happen that the cooling is not in place during molding, so that when entering the next process, due to the residual heat of the plastic pipe, the plastic pipe will produce The situation of deformation and distortion occurs, so that the melting material is returned to the furnace again, and the production is reprocessed, which not only affects the production progress, but also causes...

At present, after the plastic pipe is cooled once, it will directly enter the next process. However, sometimes it will happen that the cooling is not in place during molding, so that when entering the next process, due to the residual heat of the plastic pipe, the plastic pipe will produce Deformation and distortion occur, so the melting material is returned to the furnace again, and the production is reprocessed, which not only affects the production progress, but also causes great economic losses
