Problems solved by technology

[0004] (1) Due to the characteristics of the rubber material itself, the friction between the blade and the rubber material is relatively large. With the gradual increase of the working time of the blade, the temperature of the blade will also increase due to long-term friction. After the blade is overheated, it will cause The adhesion of the rubber material to the blade affects the normal operation of the cutting work
[0005] (2) In order to reduce the degree of frictional heat generation of the blade, the manufacturer needs to choose to cool the blade by spraying clean water during the cutting process, but due to the large amount of water during spraying, the residual clean water will mix with the rubber material , if the drying process is not carried out in time, the rubber material will become moldy, resulting in waste of rubber material

Embodiment Construction

[0037] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0038] Such as Figure 1 to Figure 8 As shown, a general-purpose rubber preparation and granulation process uses a cutting device, which includes a base frame 1, a top frame 2, a material receiving device 3 and a cutting device 4, and is prepared by the above cutting device The specific method for rubber particles is as follows:

[0039] S1. Waste recycling: recycle waste rubber materials and classify them according to the specific materials;

[0040] S2. Slitting of waste materials: using slitting equipment to slitting and processing the recycled waste rubber materials to obtain rubber fragments;

[0041] S3. Frozen crushing: After the rubber fragments are subjected to cryogenic treatment, they are crushed with a hammer crusher or a roller crushe...

Abstract

The invention relates to a general rubber preparation granulation process which uses slitting equipment. The slitting equipment comprises a base frame, a top frame, a material bearing device and a slitting device. The specific method for preparing rubber particles by adopting the slitting equipment comprises the following steps: waste recovery, waste slitting, freezing crushing, magnetic separation, packaging and warehousing. The slitting device comprises a slitting cylinder, a working frame, a mounting plate, a side plate, a slitting blade, a wetting mechanism and an extrusion column. Throughcooperation of the material bearing device and the slitting device, a waste rubber material is slit into rubber fragments with smaller sizes in a manner of simultaneous screening and slitting, and the rubber fragments with sizes meeting requirements or not are separated in time, so that the size uniformity of the slit rubber fragments is guaranteed; and meanwhile, the wetting mechanism arranged in the slitting device can lubricate and cool a slitting blade, and the situation that the rubber material adheres to the slitting blade due to overheating of the slitting blade is avoided.

Description

technical field [0001] The invention relates to the field of rubber industry, in particular to a general-purpose rubber preparation and granulation process. Background technique [0002] Rubber granules are mainly produced through the processing and production of various waste rubber, including waste rubber, tourist shoe soles, scraps, cable sheaths, rubber scraps, car mats, car tires and other waste rubber raw materials. It has a wide range of applications, mainly for sports tracks, Football field, tennis court, basketball court and other recreational and sports venues. [0003] The process of using the existing rubber granulation equipment to prepare rubber granules mainly includes slitting, crushing, screening and testing. Among them, there are some problems in the process of slitting waste rubber materials: [0004] (1) Due to the characteristics of the rubber material itself, the friction between the blade and the rubber material is relatively large. With the gradual i...
