Description

Technical Field

[0001] The utility model relates to the technical field of plastic powders, in particular to a plastic powder mixing cylinder. Background Art

[0002] Plastic powder refers to the powder or granular form of plastic raw materials after processing, grinding or granulation. These plastic powders are usually made of plastic resins, additives and other raw materials through a series of production processes. Plastic powders play an important role in the production of plastic products. They can be used as raw materials for plastic products and processed into plastic products of various shapes and uses through heating, injection molding, extrusion and other processes. Different batches or different types of plastic powders can be fully mixed through the mixing barrel to ensure the quality and performance of the final product is stable and to achieve the required formula ratio.

[0003] The mixing devices currently used for plastic powders generally use a single stirring rod to stir and mix the raw materials. The single stirring rod may not be able to fully stir all the materials evenly under certain designs and geometric shapes, resulting in the formation of dead zones in the mixing barrel. The materials in these dead zones may not be fully mixed, or it may take a longer time to achieve the ideal mixing effect, affecting the final mixing effect. During mixing, the raw materials will adhere to the mixing barrel, thus affecting the mixing effect next time. Utility Model Content

Support rods 5 are fixedly connected to both sides of the positioning cylinder 3. The side of the support rod 5 close to the support shell 2 is movably connected to the inner wall of the support shell 2 through a bearing. The support rod 5 is movably connected to the inner wall of the support shell 2 through an axle pin, so that the positioning cylinder 3 can now rotate in the support shell 2. A rotating assembly 6 is fixedly connected to one side of the support shell 2, and the rotating assembly 6 includes a first motor 601.

[0024] Three groups of connecting plates 8 are fixedly connected to the top of the surface of the positioning cylinder 3. The inner cavity of the connecting plate 8 is movably connected to a screw 81 through a rotating shaft. A spiral ring 82 is provided on the surface of the screw 81. A torsion block 83 is fixedly connected to the top of the spiral ring 82. When it is necessary to remove the cover plate 31 to clean the inner wall of the positioning cylinder 3, it is only necessary to rotate the torsion block 83 to move the spiral ring 82 away from the surface of the card block 7, and then rotate the screw 81 in the connecting plate 8 to complete the disassembly of the cover plate 31.

[0027] Working principle: first, pour the raw materials into the positioning cylinder 3 through the feed shell 32, and then close the feed shell 32 through the sealing plug 33, and then open the second motor 401. The output end of the second motor 401 will drive the transmission rod 402 to make the guide plate 403 drive multiple irregular stirring bars 404 to rotate, so that the raw materials can be mixed and stirred. However, when the transmission rod 402 rotates, it will also drive the extension plate 405 to drive the scraper 406 to rotate, thereby scraping off the raw materials adhering to the inner wall of the positioning cylinder 3 to prevent the material from solidifying on the inner wall of the positioning cylinder 3. During the stirring process, the first motor 601 can be turned on, and the output end of the first motor 601 can make the first gear plate 602 engage the second gear plate 603 to rotate the positioning cylinder 3, thereby reducing the possibility of insufficient mixing caused by a deadlock in the positioning cylinder 3 during stirring.
