A method for automatic hot drawing and reprocessing of lldpe pipes

Abstract

The invention discloses an automatic hot stretching reprocessing method of a LLDPE pipe. The method comprises the following steps: a LLDPE original pipe penetrates through an electric heating wire heating part; after the LLDPE original pipe is clamped, the LLDPE original pipe is heated through the heating of an electric heating wire and the air heat radiation; when the LLDPE pipe is gradually heated to a softening point, a slide clamping end gradually moves through an elastic element or an electromagnetic element to automatically stretch the LLDPE pipe; when the slide clamping end touches a limiting switch or a touch switch placed in a preset position, the electric heating wire heating part stops heating, so that the LLDPE pipe is stretched to a preset length; an air pump begins to work to blow cold air into the electric heating wire heating part for cooling and curing the stretched LLDPE pipe; after the curing is finished, the LLDPE pipe is taken out; and the method realizes automatic processing, is higher in effect, is convenient to control the product quality, and facilitates the technical effect of batch production.

Description

technical field [0001] The invention relates to the field of LLDPE pipe processing, in particular to a method for automatic hot drawing and reprocessing of LLDPE pipes. Background technique [0002] At present, during the use of LLDPE pipes, it is often necessary to draw the pipe and change the diameter to be suitable for different places. Usually, flame heating is used to heat the pipe to the softening point, and then the pipe is manually elongated, and then immersed in water for cooling and solidification to achieve deformation. For the purpose of diameter, this process requires both hands to use force evenly when drawing, and the pulling force must be kept inconvenient and consistent, which is not conducive to mass production and is not easy to control product quality. [0003] To sum up, in the process of realizing the technical solution of the invention in the embodiment of the present application, the inventor of the present application found that the above-mentioned t...
