[0002] Plastic particles as the basic raw material of plastic products, usually need to be premixed according to different proportions before being put into use to ensure the consistency of the performance of the final product. The existing stirring device adopts a vertical structure, the internal stirring structure is simple, the stirring efficiency is low, the problem of uneven distribution of particles is prone to occur, and residues often appear during discharging, which affects the subsequent use efficiency. At the same time, it is inconvenient to clean when changing materials, which reduces the production efficiency. Therefore, it becomes an urgent technical problem to design a plastic particle stirring device with reasonable structure, convenient mixing, rapid discharging and easy cleaning. SUMMARY

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0005] A plastic particle stirring device convenient for quick mixing, comprising a stirring barrel, a driving mechanism, a stirring mechanism and a discharging structure.

[0006] The stirring barrel is of a cylindrical structure, has an openable cover plate at the top, is closed at the bottom, and has an observation window on the barrel wall.

[0007] The stirring mechanism comprises a vertically arranged stirring shaft, a plurality of spiral blades are fixed on the stirring shaft, and the spiral blades are arranged in reverse directions upward and downward.

[0008] The driving mechanism is arranged at the top of the stirring barrel and connected with the stirring shaft, and rotates the stirring shaft through a motor.

[0009] The discharging structure is a flap type discharge port arranged at the bottom of the stirring barrel and has a control mechanism to control its opening and closing.

[0010] Further, the spiral blades are arranged at intervals with the barrel wall to ensure that the particles are fully mixed along the spiral path; the gap is preferably 1-5mm (which can be adjusted according to specific requirements), which can form an effective particle flow channel to avoid blockage and accumulation, while ensuring the stirring efficiency and reducing the direct friction between the spiral blades and the barrel wall to improve the service life.

[0011] Further, the inner surface of the stirring barrel is provided with an anti-sticking coating to facilitate cleaning and changing materials.

[0012] Furthermore, the discharge structure is equipped with an auxiliary scraper to prevent particle residue.

[0013] Furthermore, a dustproof ring is provided on the inner side of the cover plate to effectively prevent dust from leaking out. Attached Figure Description

[0020] Example 1: As Figure 1 As shown, a plastic granule mixing device for rapid mixing includes a mixing tank 1, a drive mechanism 2, a mixing mechanism 3, and a discharge structure 6. The mixing tank 1 is a vertically arranged cylinder with an openable cover 7 at the top and a closed bottom. A transparent observation window 8 is provided on the tank wall, allowing the user to easily observe the internal mixing process. The observation window 8 is preferably made of a transparent and impact-resistant material such as polycarbonate (PC) or acrylic (PMMA) (this can be adjusted according to specific circumstances), possessing good light transmittance and impact resistance, capable of withstanding particle impacts during mixing, while ensuring clear observation and extending the device's lifespan.

[0021] Example 2: Figures 2-3 As shown, the stirring mechanism 3 includes a stirring shaft 4 connected to the drive mechanism 2. Several spiral blades 5 are fixedly mounted on the stirring shaft 4, arranged in opposite directions. The upper blades rotate clockwise to press the upper particles downwards, while the lower blades rotate counter-clockwise to push the bottom particles upwards. The two sets of blades create a turbulent flow, enhancing the particle mixing path and improving mixing uniformity and speed. The stirring shaft 4 is driven to rotate by a top motor. The drive mechanism 2 includes a motor, a coupling, and an optional reducer. The motor output shaft is connected to the stirring shaft 4 via the coupling, allowing for speed control to adapt to different particle types and mixing requirements.

[0022] Example 3:Figure 4 As shown, the discharge structure 6 is a flap design, provided at the center of the bottom of the mixing barrel 1, and is driven to open or close by a control mechanism, which includes an electrically controlled driving device. The flap is hinged to the edge of the barrel bottom, and the opening angle is controllable, and when closed, it is attached to the barrel bottom by a sealing ring to ensure sealing performance. To avoid particle residues, an auxiliary scraper 9 is provided on the inside of the flap, which is installed on the surface of the flap by screwing, is convenient to disassemble and replace, and the material is preferably elastic rubber or wear-resistant plastic (which can be adjusted according to specific applications), which can scrape off the residual material on the bottom of the barrel when the flap is opened, effectively improving the discharge efficiency and reducing manual cleaning work.

[0023] Example four: as Figure 5 As shown, the inside of the cover plate 7 is provided with a dustproof ring 10, which is in sealing contact with the barrel body when the cover plate is closed, preventing dust from escaping during the mixing process and improving the working environment.

[0024] Example five: the inner surface of the mixing barrel 1 is coated with an anti-sticking coating, which facilitates quick cleaning of residual particles after mixing is completed, and also facilitates the replacement and mixing of different types of plastic particles. The anti-sticking coating is preferably made of polytetrafluoroethylene or ceramic composite coating (which can be adjusted according to specific conditions), which has good anti-sticking, corrosion resistance and high temperature resistance, and is suitable for the mixing of various electrostatic adsorption or oil-containing plastic particles. It is easy to clean and effectively reduces residues.

[0025] Example six: the bottom of the mixing barrel 1 is provided with a support base, which is a metal welded structure, provided with a plurality of legs, and each leg is provided with a shock pad at the bottom. The shock pad is preferably made of rubber or elastic composite material (which can be adjusted according to the use scene), which has good buffering and vibration absorbing performance, and can effectively reduce the influence of vibration generated during mixing on the stability of the device, and improve the safety and reliability of the overall operation.

[0026] Example seven: the spiral blade 5 is preferably made of stainless steel, manganese steel or other wear-resistant metal materials (which can be adjusted according to the actual mixing material properties), which has excellent wear resistance and structural strength, and can adapt to high-frequency and high-load particle mixing conditions, prolong the service life of the device, and reduce the problem of uneven mixing caused by blade wear.
