Description

Technical Field

[0001] This utility model belongs to the field of plastic particle production technology, and specifically relates to a color mixing device for plastic particle production. Background Technology

[0002] Plastic particle color mixing refers to the process of adding pigments, masterbatches, and other materials during plastic processing to make plastic particles present different colors or achieve color mixing.

[0003] Currently, Chinese utility model patent CN213440489U discloses a plastic particle color mixing machine. Existing color mixing methods involve directly adding pigment powder to plastic particles and then mixing and molding them. However, existing color mixing equipment uses a single mixing method, with a fixed rotation direction and position of the stirring rod, making it difficult to fully mix the plastic at the edges, resulting in poor color mixing effects. Furthermore, after the plastic particle color mixing is complete, it is inconvenient to remove the stirring rod from the tank for cleaning; cleaning directly inside the tank is also inconvenient and can easily lead to incomplete cleaning, leaving pigment residue and affecting subsequent use. Utility Model Content

[0004] The purpose of this invention is to provide a color mixing device for the production of plastic particles, which has the advantages of improving the color mixing and stirring effect of plastic particles and facilitating the removal of the mixing device for cleaning.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a color mixing device for the production of plastic particles, comprising a color mixing tank, a cover plate slidably connected to the top of the color mixing tank, a motor bolted to the top of the cover plate, a central stirring rod bolted to the output end of the motor, a turntable slidably connected to the cover plate and fixedly sleeved on the top surface of the central stirring rod, and an edge stirring rod rotatably connected to both sides of the bottom of the turntable, a disc gear bolted to the top of each of the two edge stirring rods, and an annular rack meshing with the disc gear bolted to the inner surface of the cover plate.

[0006] The above technical solution involves rotating the central stirring rod to agitate the plastic particles and color powder at the center of the mixing tank. Then, the edge stirring rods rotate around the center of the central stirring rod at the bottom of the turntable, while simultaneously rotating on their own axes. This ensures thorough agitation of the plastic particles and color powder at the edges of the mixing tank, further improving the agitation effect. By rotating the threaded rod and engaging the threaded sleeve, the friction of the threaded engagement causes the cover plate to slide upwards on top of the mixing tank, lifting the central and edge stirring rods from inside the tank. This facilitates cleaning of the central and edge stirring rods, improving practicality.

[0007] The present invention is further configured such that a fixing plate is bolted to one side of the top of the color mixing tank, a threaded rod is rotatably connected inside the fixing plate, and a threaded sleeve that is threadedly connected to the threaded rod is bolted to the side of the cover plate near the fixing plate.

[0008] By adopting the above technical solution, the central stirring rod and the edge stirring rod at the bottom of the cover plate can be lifted out of the mixing tank, thereby facilitating the cleaning of the central stirring rod and the edge stirring rod and improving practicality.

[0009] The present invention is further configured such that the top and bottom of the surface of the color mixing tank away from the fixed plate are both provided with material inlets, and the inside of the two material inlets is threaded with a sealing plug.

[0010] Using the above technical solution, plastic particles and color powder can be added to or discharged into the mixing tank through the material outlet, while the material outlet can be sealed by a sealing plug.

[0011] The present invention is further provided that the interior of the fixing plate is provided with a limiting groove that is slidably connected to the threaded sleeve.

[0012] The above technical solution is used to limit the up and down sliding of the threaded sleeve and improve the stability of the cover plate lifting.

[0013] The present invention is further provided that the bottom of the fixed plate is rotatably connected to a handwheel welded to the threaded rod.

[0014] The above technical solution facilitates the rotation of the threaded rod by turning the handwheel.

[0015] The present invention is further configured such that a sealing ring that is slidably connected to the color mixing tank is fixedly sleeved at the bottom of the surface of the cover plate.

[0016] The above technical solution improves the sealing performance of the cover plate on the mixing tank after it is lowered, preventing moisture from seeping into the interior.

[0017] The present invention is further provided that a ventilation mesh for use with the motor is bolted to the top of the cover plate.

[0018] The above technical solution is used to ventilate and dissipate heat from the motor, and at the same time, it can prevent foreign objects from entering.

[0019] The present invention is further provided that a graduated observation window is bolted to the other side of the surface of the color mixing tank.

[0020] The above technical solution facilitates observation of the volume of plastic particles and color powder inside the mixing tank, as well as the mixing and blending process.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. The central stirring rod is rotated to agitate the plastic particles and color powder at the center of the mixing tank. Then, the edge stirring rods rotate around the center of the central stirring rod at the bottom of the turntable, while the edge stirring rods rotate on their own axis, thereby fully agitating the plastic particles and color powder at the edge of the mixing tank and further improving the agitation effect.

[0023] 2. By rotating the threaded rod and engaging the threaded sleeve, the threaded sleeve, through the friction of the threaded engagement, causes the cover plate to slide upwards on top of the mixing tank, lifting the central and edge stirring rods from inside the mixing tank. This facilitates cleaning of the central and edge stirring rods, improving practicality. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1:

[0030] refer to Figure 1 , Figure 2 , Figure 3A color mixing device for producing plastic particles includes a color mixing tank 1. The device is characterized by: a cover plate 2 slidably connected to the top of the color mixing tank 1; a motor 3 bolted to the top of the cover plate 2; a central stirring rod 4 bolted to the output end of the motor 3; a turntable 5 slidably connected to the cover plate 2 and fixedly sleeved on the top surface of the central stirring rod 4; edge stirring rods 6 rotatably connected to both sides of the bottom of the turntable 5; a disc gear 7 bolted to the top of each edge stirring rod 6; and an annular rack 8 meshing with the disc gear 7 bolted to the inner surface of the cover plate 2. The central stirring rod 4 is rotated to stir the plastic particles and color powder at the center of the color mixing tank 1. Then, the edge stirring rods 6 rotate around the center of the central stirring rod 4 at the bottom of the turntable 5, while simultaneously rotating on their own axis, thereby fully stirring the plastic particles and color powder at the edges of the color mixing tank 1, further improving the stirring effect.

[0031] refer to Figure 1 , Figure 2 A ventilation mesh 14, which works in conjunction with the motor 3, is bolted to the top of the cover plate 2. This mesh is used to ventilate and dissipate heat from the motor 3, and also to prevent debris from entering.

[0032] refer to Figure 1 A graduated observation window 15 is bolted to the other side of the surface of the color mixing tank 1. This allows for easy observation of the volume of plastic particles and color powder inside the color mixing tank 1, as well as the mixing process.

[0033] Brief description of the usage process: Plastic particles and color powder are added to the interior of the mixing tank 1 in a specific ratio. Then, the motor 3 is turned on to drive the central stirring rod 4 to rotate, causing the central stirring rod 4 to stir the plastic particles and color powder in the center of the mixing tank 1. Subsequently, the motor 3 synchronously drives the turntable 5 to rotate. During the rotation of the turntable 5, the edge stirring rods 6 on both sides rotate around the center of the central stirring rod 4, causing them to stir the plastic particles and color powder at the edges of the mixing tank 1. At the same time, during the rotation of the edge stirring rods 6 around the central stirring rod 4, the disc gear 7 and the ring rack 8 mesh with each other, allowing the edge stirring rods 6 to rotate on their own at the bottom of the turntable 5, further improving the stirring effect of the plastic particles and color powder.

[0034] Example 2:

[0035] refer to Figure 1 , Figure 2A color mixing device for plastic particle production includes a color mixing tank 1 with a fixed plate 9 bolted to one side of its top. A threaded rod 10 is rotatably connected inside the fixed plate 9. A threaded sleeve 11, threadedly engaged with the threaded rod 10, is bolted to the side of the cover plate 2 closest to the fixed plate 9. By rotating the threaded rod 10 and threaded sleeve 11, the threaded sleeve 11, through the frictional force of the threaded engagement, causes the cover plate 2 to slide upwards on top of the color mixing tank 1, lifting the central stirring rod 4 and the edge stirring rod 6 at the bottom of the cover plate 2 out of the color mixing tank 1. This facilitates cleaning of the central stirring rod 4 and the edge stirring rod 6, improving practicality.

[0036] refer to Figure 1 , Figure 2 The mixing tank 1 has material inlets 12 on both the top and bottom sides away from the fixed plate 9. Each material inlet 12 has a threaded sealing plug 13 inside. Plastic particles and color powder can be added to or discharged into the mixing tank 1 through the material inlets 12, and the sealing plugs 13 can cover the material inlets 12 to seal them.

[0037] refer to Figure 1 , Figure 2 The fixed plate 9 has a limiting groove 16 inside that slides with the threaded sleeve 11. This groove is used to limit the up and down sliding of the threaded sleeve 11 and improve the stability of the lifting and lowering of the cover plate 2.

[0038] refer to Figure 2 A handwheel 18, welded to the threaded rod 10, is rotatably connected to the bottom of the fixed plate 9. This allows the threaded rod 10 to be rotated by turning the handwheel 18.

[0039] refer to Figure 2 A sealing ring 17, which is slidably connected to the mixing tank 1, is fixedly sleeved at the bottom of the surface of the cover plate 2. This improves the sealing performance of the cover plate 2 when it is lowered onto the mixing tank 1, preventing moisture from seeping into the interior.

[0040] Brief description of the usage process: By rotating the threaded rod 10 and engaging the threaded sleeve 11, the threaded sleeve 11 causes the cover plate 2 to slide upwards on top of the mixing tank 1 through the friction of the threaded engagement. After the plastic particles and color powder inside the mixing tank 1 have been mixed and discharged, the central stirring rod 4 and the edge stirring rod 6 at the bottom of the cover plate 2 can be lifted out of the mixing tank 1 for thorough cleaning. The water that slips off during cleaning can fall into the mixing tank 1, further cleaning the inside before being discharged. Finally, after cleaning, the threaded rod 10 is rotated in the opposite direction to engage the threaded sleeve 11, causing the cover plate 2 to fall back down and re-seal the top of the mixing tank 1.

[0041] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0042] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
