Description

TECHNICAL FIELD

[0002] The rubber waste generated in the shoe production process is one of the important solid wastes in the shoe manufacturing industry, mainly coming from the manufacturing of shoe soles, mold trimming, corner cutting and unqualified products and the like. The rubber waste is usually recycled. According to different types of production shoes, the rubber is divided into different types, and the EVA foamed rubber is the main raw material for producing slippers and beach shoes. In the process of recycling the EVA foamed rubber, the large waste is usually crushed into small particles by special equipment for regenerated rubber or filling material, so that a rubber waste recycling device for shoe production is needed for processing. The following problems exist in the processing: 1. The rubber waste for shoe production usually has a large block structure, which needs to be crushed into small pieces by a shearing and crushing mechanism for subsequent granulation and reuse. In the shearing and crushing process, the rubber and the tearing blade are usually torn by a double-shaft tearing machine. However, friction occurs between the rubber and the tearing blade during the tearing process, which generates heat and causes the blade to overheat, resulting in the adhesion of the rubber during the tearing process, affecting the effect of subsequent shearing and tearing, and even causing equipment jamming and reducing production efficiency.

[0003] 2. The rubber waste includes unqualified shoe sole products. The shoe sole is usually injection molded by a mold. In order to facilitate demolding of the shoe sole product, a release agent is usually coated on the mold. Therefore, the discarded shoe sole product is adhered with the release agent, which affects the subsequent recycling. The existing equipment usually does not have the function of removing the release agent on the crushed rubber block, which affects the quality of the subsequent recycled products. SUMMARY

[0027] Please refer to Figure 2 and Figure 5The high-pressure water pump 91 is fixedly installed on the bottom plate of the cleaning box body 8. A water supplement pipe (not shown in the figure) is arranged on the cleaning box body 8 and is connected with the water supplement pump, so as to realize automatic water supplement of the cleaning box body 8. A drain port is arranged at the top right side of the cleaning box body 8, so as to facilitate discharge of the rubber blocks after rinsing. The water supplement speed and the drain speed are set according to requirements. The suction pipe 92 is fixedly installed at the input end of the high-pressure water pump 91. The end of the suction pipe 92 away from the high-pressure water pump 91 is fixedly communicated with the bottom of the cleaning box body 8. The drain pipe 93 is fixedly installed at the output end of the high-pressure water pump 91.
