Mixing machine for engineering plastic modification

Abstract

The invention discloses a mixing machine for engineering plastic modification. The mixing machine structurally comprises a top cover, a motor, a mixing drum, an operation case, a support frame and a discharging base plate, wherein the top cover is arranged at the upper end of the mixing drum; a rotating shaft inside the mixing drum is driven by the motor; the operation case controls the motor; thebottom of the mixing drum and the discharging base plate internally communicate with each other and are welded together; the support frame is mechanically coupled to the outer surfaces of the mixingdrum and the discharging base plate; and four chucks, telescopic stirring shafts and the rotating shaft are arranged inside the mixing drum. According to the mixing machine, through the combined action of inner telescopic rods, outer fixing rods, sliding blocks and walking devices, when the telescopic stirring shafts with the telescopic function are opened, auxiliary expansion wheels open telescopic plastic tubes to make full contact with the wall of the mixing drum, the telescopic plastic tubes are used for scraping the water on the drum wall before mixing, the humid environment in the mixingdrum is avoided, and a problem of difficulty in dehumidification of the drum wall is solved.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to a mixer for engineering plastic modification. Background technique [0002] During the manufacturing process of engineering plastics, it is sometimes necessary to mix various engineering plastics together to prepare modified mixed engineering plastics. This modified engineering plastics needs to be mixed with a mixer. During preparation, these Engineering plastics are added to the mixer. There is a special mixing cylinder combined with a stirring system in the mixer to make the mixing more complete. However, the existing mixing cylinder is made of stainless steel. Before mixing, it is affected by the deliquescence of the environment. There are a lot of water droplets attached to the inner wall. When making plastic solid / solid mixing, it is difficult for the user to fully remove the water on the cylinder wall due to the limitation of the diameter of the cylinder mouth, resulting ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a mixer for engineering plastics modification, to solve the problem of environmental deliquescence before mixing, a large amount of water droplets attached to the inner wall of the mixing cylinder, when making plastic solid / solid mixing Due to the limitation of the diameter of the barrel mouth, it is difficult for the user to fully remove the water on the barrel wall, resulting in uneven mixing, which will cause obvious cracks, material flakes, and even technical problems on the surface of the post-processed product.
