A kind of preparation method of anti-collision strip

Abstract

The invention provides an anti-collision strip preparing method. The anti-collision strip preparing method comprises the steps that EPDM is extruded and formed through an extruder, an anti-collision strip obtained after extrusion forming is subjected to vulcanization through salt bath equipment, the anti-collision strip is dragged through a conveying belt to pass through liquid industrial salt insalt bath equipment, and the anti-collision strip is in a suspension state in the liquid industrial salt; after the anti-collision strip gets out of the liquid industrial salt, the anti-collision strip walks towards the inclined upper portion of the liquid level of the liquid industrial salt by the first set distance and then obliquely downwards moves by the second set distance, and finally, an output conveying belt outputs the anti-collision strip out of a salt bath groove; a spraying head on the inner side of a U-shaped spraying pipe rack is used for spraying water for preliminary cleaning of the anti-collision strip; a plurality of rotation cleaning mechanisms are utilized for deep cleaning of the anti-collision strip; and dry blowing, hot air drying and cooling are conducted, and rolling and disc forming are finally achieved. In the method, the anti-collision strip is suspended in the liquid salt, abrasion of the anti-collision strip can be reduced, and the quality of the anti-collision strip is improved; and steam input equipment is used for inputting steam, and it can be guaranteed that the temperature in the salt bath groove is maintained at the set value.

Description

technical field [0001] The invention relates to the field of anti-collision strips, in particular to a preparation method of anti-collision strips. Background technique [0002] In the existing anti-collision strip production process, the newly extruded anti-collision strip is heated and vulcanized by hot air, but because the anti-collision strip needs to walk on the conveyor belt during the hot-air vulcanization process, it is easy to produce some Scratches and slight extrusion deformations affect the quality and quality of the anti-collision strips. At the same time, it is difficult to control the temperature of the hot air heating so that each part can reach an accurate value, so that the anti-collision strip is heated unevenly and affects its vulcanization effect. Contents of the invention [0003] The purpose of the present invention is to provide a preparation method of the anti-collision strip to overcome the deficiencies of the prior art. [0004] To achieve the ...

[0002] In the existing anti-collision strip production process, the newly extruded anti-collision strip is heated and vulcanized by hot air, but because the anti-collision strip needs to walk on the conveyor belt during the hot-air vulcanization process, it is easy to produce some Scratches and micro-extrusion deformations, which affect the quality and quality of the anti-collision strip

At the same time, it is difficult to control the temperature of the hot air heating so that each part can reach an accurate value, so that the anti-collision strip is heated unevenly and affects its vulcanization effect.
