[0002] In the field of plastic product production, for the convenience and universality of raw material procurement and inventory, plastic product manufacturers usually purchase monomer plastic particles. During production, according to customer requirements, additives such as fillers, plasticizers, stabilizers, lubricants, and colorants are added to the monomer plastic particles in a certain proportion for mixing, so as to produce plastic products of different colors and shapes. A stirring and mixing device is required during the plastic production process.

[0003] Most of the existing stirring and mixing devices drive the stirring rod to rotate through a motor to stir the plastic raw materials inside the stirring barrel. Stirring solely by the stirring rod results in low stirring efficiency and unsatisfactory stirring effect. Therefore, we propose a stirring and mixing device for plastic production and processing.

[0026] To make the purpose, technical solutions, and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail in conjunction with the accompanying drawings.

[0027] The present utility model provides a stirring and mixing device for plastic production and processing. By setting the first motor, the entire stirring cylinder can be driven to flip and rotate, so that the raw materials inside the stirring cylinder are flipped and rotated. While the raw materials are flipped and rotated, they are also stirred by the stirring component. Compared with the existing single stirring by the stirring rod, the present utility model has the advantages of high stirring efficiency and good stirring effect.

[0028] Figures 1 - 3 Shown is a structural schematic diagram of an embodiment of a stirring and mixing device for plastic production and processing according to the present utility model. Please refer to Figures 1 - 3 For a stirring and mixing device for plastic production and processing in this embodiment, its main body part includes a vertical plate 100, a mixing cylinder 200, a flipping and rotating assembly 300, and a stirring assembly 400.

[0029] There are two vertical plates 100 arranged vertically, and a fixed plate 101 is fixed at the lower end of the inner sides of the two vertical plates 100. As a preference, in this embodiment, a bottom plate 103 is vertically fixed at the lower end of the vertical plate 100, and bolts 104 are arranged on the bottom plate 103. Under the action of the bottom plate 103, the vertical plate 100 is installed at a specified position through the bolts 104, so as to ensure the stable placement of the vertical plate 100. The upper end surface of the fixed plate 101 is inclined, and a diversion groove 105 is opened in the middle of the upper end of the fixed plate 101. The diversion groove 105 opened on the fixed plate 101 can conduct the material after mixing and stirring for feeding when the feeding is carried out after the stirring and mixing is completed.

[0030] The mixing cylinder 200 is arranged at the upper end of the inner sides of the two vertical plates 100. An inlet is opened at the upper end of the mixing cylinder 200, and a sealing plate 201 is installed in the inlet by thread. A handle is arranged on the sealing plate 201. As a preference, in this embodiment, limiting rods 202 are vertically fixed on the upper and lower sides of the middle part of the opposite outer walls of the mixing cylinder 200. An annular limiting groove 102 is opened on the inner side of the vertical plate 100. The outer wall of the limiting rod 202 is attached to the inner wall of the limiting groove 102. When the mixing cylinder 200 is flipped and rotated by the first motor 310, the limiting rods 202 on its outer wall rotate synchronously in the limiting groove 102. During the rotation process, a certain frictional force is generated between the limiting rod 202 and the limiting groove 102, so as to ensure the stability of the mixing cylinder 200 during the rotation process.

[0031] The flipping and rotating assembly 300 includes a first motor 310 arranged on the outer side of one of the vertical plates 100, a rotating shaft 320 fixed at the output end of the first motor 310, and a driven shaft 330 vertically fixed on the outer wall of the mixing cylinder 200. The rotating shaft 320 is fixedly connected to the mixing cylinder 200.

[0032] The stirring assembly 400 includes a second motor 410 disposed in the middle of the upper end of the stirring cylinder 200, a stirring shaft 420 fixed to the output end of the second motor 410, and stirring rods 430 disposed on the outer wall of the stirring shaft 420. Preferably, in this embodiment, a scraper 431 is vertically disposed on the outer side of the stirring rod 430, and the outer wall of the scraper 431 is attached to the inner wall of the stirring cylinder 200. The scraper 431 disposed on the outer side of the stirring rod 430 rotates synchronously in the stirring cylinder 200 as the stirring rod 430 rotates. During the rotation process, the scraper 431 scrapes off the raw materials adhering to the inner wall of the stirring cylinder 200, thereby preventing the raw materials from sticking to the inner wall of the stirring cylinder 200. At the same time, in the later stage, the scraper 431 also facilitates scraping and cleaning of the residual materials adhering to the inner wall of the stirring cylinder 200. A plurality of scrapers 431 are provided, and the plurality of scrapers 431 provided can enhance the cleaning of the raw materials adhering to the inner wall of the stirring cylinder 200.

[0033] Combined with Figures 1 - 3 , a stirring and mixing device for plastic production and processing in this embodiment is specifically used as follows: The raw materials to be mixed are put into the interior of the stirring cylinder 200 through the feed inlet, and then the feed inlet is blocked by the sealing plate 201. The first motor 310 and the second motor 410 are started. The first motor 310 drives the rotating shaft 320 to rotate, thereby driving the stirring cylinder 200 to rotate in a flipping manner. The second motor 410 drives the stirring shaft 420 and the stirring rods 430 to rotate. During the flipping rotation process of the stirring cylinder 200, the raw materials inside it also rotate in a flipping manner, and the raw materials are also stirred by the stirring rods 430 during the flipping rotation process. Through the provided flipping rotation assembly 300 and the stirring assembly 400, the raw materials are double-stirred and mixed. Compared with the existing single stirring by the stirring rods 430, the present invention has the advantages of high stirring efficiency and good stirring effect.

[0034] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention can be combined with each other in any way. The reason for not exhaustively describing the situations of these combinations in this specification is only to save space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
