Since the bottom is detachable, it is easier for personnel to enter than the top, and the safety is also higher.

[0012] A further improvement of this utility model is that the stirring mechanism includes a servo motor fixedly installed in the middle of the top surface of the mixing tank. A rotating shaft is fixedly installed at the output end of the servo motor. A stirring frame is installed horizontally through the surface of the rotating shaft. The servo motor drives the rotating shaft to rotate, which in turn drives the stirring frame to rotate and achieves the mixing of plastic granule raw materials.

[0013] A further improvement of this utility model is that the scraping assembly includes a U-shaped frame fixedly installed on the surface of the rotating shaft, a connecting spring fixedly installed on the surface of the U-shaped frame, and a scraping rod fixedly installed at one end of the connecting spring. By installing the scraping assembly on the rotating shaft, it is possible to move the equipment while stirring and rotating, thereby facilitating contact with the inner wall of the tank for scraping, preventing excessive adhesion to the inner wall after long-term mixing, which affects the service life of the device and makes it difficult to clean.

[0014] A further improvement of this utility model is that the mixing tank body and the bottom cover body are connected by a slot and a block, and the rotating shaft is inserted into the mixing tank body. The insertion method facilitates installation while preventing the tank body from affecting the rotation.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] This utility model provides a mixing device for producing plastic granules. By setting a detachable bottom cover and using a locking block and slot connection method, it is easy to disassemble later, thereby enabling cleaning of the inside of the tank after disassembly. Because the bottom is detachable, it is easier for personnel to enter than the top, and the safety is also higher.

[0017] This utility model provides a mixing device for producing plastic granules. By installing a scraping component on the rotating shaft, it can achieve mixing and rotation while being easy to move, thereby facilitating contact with the inner wall of the tank for scraping treatment. This prevents excessive material adhesion to the inner wall after long-term mixing, which affects the service life of the device and makes it difficult to clean.

[0018] This utility model provides a mixing device for producing plastic granules. By installing a visible panel on the mixing tank, the mixing situation inside can be observed, and the extension and contraction of the connecting spring can also be easily observed. After the connecting spring is contracted and tightened, the detachable bottom cover can be opened in time to clean the tank and scraper rod. Attached Figure Description
