Description

Technical Field

[0001] This utility model relates to the field of rubber mixing machine technology, and in particular to a rubber mixing machine for rubber material production. Background Technology

[0002] With the booming development of polymer materials science, polymer materials such as rubber and plastics are widely used in cutting-edge technologies and daily life. As people's demands for rubber increase, rubber companies are also exploring production methods that meet the requirements of high efficiency, low consumption, automation, and environmental protection. The basic process of rubber production is as follows: first, raw rubber granules, accelerators, anti-sticking agents, activators, and other components are mixed in a certain proportion. Then, processes such as plasticizing and mixing are used to improve the plasticity and flowability of the rubber. Finally, the rubber strips are processed, pressed into molds, cut, and packaged.

[0003] In existing rubber mixing machines, a motor drives a roller shaft, which rotates the mixing box by cooperating with a track on the outside of the mixing box. However, during use, dust and other debris accumulate on the inside of the track, which can cause the mixing box to rotate unstably after prolonged use, affecting the normal operation of the mixing machine.

[0006] Furthermore, a motor is provided at the end of the front drive roller, and a rotating shaft is fixedly connected to the power output shaft of the motor.

[0007] Furthermore, two sets of knurling are provided on the outer center of the mixing box, and a set of guide rails are provided on each of the left and right sides of the outer side of the mixing box.

[0008] Furthermore, the knurling is installed in conjunction with the drive roller.

[0009] Furthermore, a positioning wheel is fitted on the outer side of the guide rail, and the positioning wheel is detachably mounted to the rotating shaft by bolts.

[0010] Furthermore, a blower is fixedly installed on the upper right rear side of the base, and an air duct is fixedly connected to the left end of the blower. The left end of the air duct is connected to the interior of the protective frame.

[0011] The beneficial effects of this utility model are: by adjusting the position of the two sets of positioning wheels, the positioning wheels and the guide rail cooperate to complete the overall positioning and limiting of the mixing box, preventing the mixing box from shaking left and right, and starting the blower to blow air into the inside of the protective frame to prevent external dust from entering the inside of the protective frame through the brush, so that the outside of the mixing box is kept clean at all times.
