Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to a rubber granule extruder. Background Art

[0002] Usually, waste rubber products (such as waste rubber) are used as raw materials for the extruder after being processed. The raw materials usually need to be crushed, cleaned and pretreated to ensure the quality and efficiency of the extrusion process. The raw materials are fed into the feed inlet of the extruder, and then, under the action of heating and pressure, a flowing state is formed inside the machine. During the extrusion process, the rubber is pushed and compressed continuously through a series of rotating screws or pistons. In order to solve the problem of waste rubber regeneration, the rubber granule extruder came into being. It heats and extrudes the waste rubber to form granular recycled rubber materials, which can be used as raw materials for new rubber products. This technology not only improves the recycling rate of waste, but also can produce rubber granules with stable quality and high cost-effectiveness, meeting the needs of rubber product production. Publication No.: CN209869137U discloses a rubber granule extruder, including an extrusion device cylinder body. An extrusion device feed screw is arranged inside the extrusion device cylinder body. An extrusion device screw rotation motor is arranged on the left side of the extrusion device cylinder body. The left end of the extrusion device feed screw is fixedly connected with the extrusion device screw rotation motor. The extrusion device feed screw passes through the inner wall of the left end of the extrusion device cylinder body. An extrusion device feed inlet is arranged above the left end of the extrusion device cylinder body. The bottom of the extrusion device feed inlet is hermetically connected with the top of the left end of the extrusion device cylinder body. The structure of the utility model is simple and easy to use. The inclined-edge blade can ensure that the rubber granules are of uniform size, and the cutting is rapid without generating dust. Most parts of the equipment are detachable and very convenient to clean. A dredging device is arranged at the feeding part to prevent rubber from blocking at the feeding part. The material guiding groove can control the discharging direction by adjusting the angle. However, for the above-mentioned equipment, after the equipment is used, some raw materials may remain inside the extrusion assembly, and the equipment cannot be disassembled and cleaned. After the equipment is placed, the raw materials may dry out, resulting in blockage of the extrusion assembly and affecting the use of subsequent equipment, which needs to be improved.
