A top cover is fixedly installed at the top of the housing, and a motor is fixedly installed on the top of the inner wall of the top cover. In this mixer for plastic processing, when plastic processing begins, the plastic product is placed into the mixing drum. The motor located at the top of the housing provides power to cause the stirring wheel, which is mounted on a rotating shaft, to stir the plastic. Meanwhile, a dye pump located at the top of the housing operates, outputting dye to a filter box for impurity removal.

[0004] Although the aforementioned patent can mix and stir plastics using a stirring wheel, the simple unidirectional rotation for mixing is inefficient and requires a long time to complete a high degree of mixing. At the same time, feeding is cumbersome and manual feeding is time-consuming and labor-intensive. Therefore, a plastic processing mixer is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, simple unidirectional rotation for mixing is inefficient and requires a long time to complete a high degree of mixing. At the same time, feeding is cumbersome and manual feeding is time-consuming and labor-intensive. Therefore, this utility model proposes a mixer for plastic processing.

[0007] The feeding assembly includes a feeding pipe fixedly connected to one end of the feed pipe, a device box fixedly connected to the bottom end of the feeding pipe, a motor sleeved inside the device box, a spiral feeding rod fixedly connected to the output end of the motor, an opening provided on the side of the feeding pipe, a connecting pipe fixedly connected to the side of the opening, and a conical feeding trough fixedly connected to the top end of the connecting pipe.

[0008] The stirring assembly includes a frame fixedly connected to the side of a drive motor. A drive wheel is fixedly connected to one end of the drive motor through the frame. An upper driven wheel and a lower driven wheel are respectively engaged on both sides of the drive wheel. A rotating rod is fixedly connected to the surface of the upper driven wheel. A rotating tube is fixedly connected inside the lower driven wheel. A rotating rod is rotatably connected inside the rotating tube. A connecting plate is fixedly connected to the bottom end of both the rotating tube and the rotating rod. Stirring blades are fixedly connected to the bottom surfaces of both connecting plates in a rectangular array.

[0009] Preferably, the device box is fixedly disposed at the center of the bottom end of the feeding tube, and the output end of the motor extends vertically upward into the inside of the feeding tube and is coaxially connected to the spiral feeding rod.

[0010] Preferably, the top end of the spiral feed rod extends to the connection between the feed pipe and the feed tube, and the outer diameter of the spiral feed rod is clearance-fitted with the inner wall of the feed tube.

[0011] Preferably, the rotating tube is rotatably connected to the rotating rod via a lower driven wheel, and the top and bottom ends of the rotating tube are both shorter than the corresponding ends of the rotating rod, forming a coaxial counter-rotating structure between the rotating tube and the rotating rod.

[0014] The advantages of this utility model are:

[0015] 1.

This causes the stirring blades on the bottom surfaces of the two sets of connecting plates to form a cross motion trajectory. The shearing force of the opposite rotation enhances the mixing uniformity of the plastic material. Compared with unidirectional stirring, this method shortens the stirring time and improves the stirring efficiency.

[0016] 2. This utility model uses a spiral feeding rod in the feeding assembly, driven by a motor, to lift the plastic material fed into the conical feeding trough along the feeding pipe to the inlet pipe. The spiral conveying structure realizes automated vertical feeding, avoiding the tedious operation of manually carrying materials to the top inlet of the mixing tank, while reducing the risk of material spillage and improving feeding safety.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-4As shown, a plastic processing mixer includes a mixing cylinder 1. A feed inlet is provided on the side of the mixing cylinder 1. A feed pipe 2 is connected through the top of the feed inlet. A feeding assembly 3 is connected through one end of the feed pipe 2. An equipment plate 4 is fixedly connected to the back of the mixing cylinder 1. A drive motor 5 is fixedly connected to the side of the equipment plate 4. A mixing assembly 6 is fixedly connected to the output end of the drive motor 5. The feeding assembly 3 includes a feeding pipe 31 fixedly connected to one end of the feed pipe 2. An equipment box 32 is fixedly connected to the bottom end of the feeding pipe 31. A motor 33 is sleeved inside the equipment box 32. A spiral feeding rod 34 is fixedly connected to the output end of the motor 33. An opening is provided on the side of the feeding pipe 31. A connecting pipe 35 is fixedly connected to the side of the opening. A conical discharge trough 36 is fixedly connected to the top of the connecting pipe 35.

[0025] During operation, the stirring assembly 6 drives the driving wheel 62 to rotate via the drive motor 5. The driving wheel 62 simultaneously engages with the upper driven wheel 63 and the lower driven wheel 64 to achieve reverse transmission. The upper driven wheel 63 drives the rotating rod 65 to rotate clockwise, and the lower driven wheel 64 drives the rotating tube 66 to rotate counterclockwise. The rotating tube 66 is sleeved on the outside of the rotating rod 65. Two sets of connecting plates 67 are fixed to the bottom of the rotating rod 65 and the rotating tube 66, respectively. This causes the rectangular array of stirring blades 68 to form a cross shear force in the stirring cylinder 1, accelerating the mixing process of the plastic material through bidirectional stirring.

[0026] Furthermore, the stirring assembly 6 includes a frame 61 fixedly connected to the side of the drive motor 5. The output end of the drive motor 5 is fixedly connected to one end of the frame 61 with a drive wheel 62. The two sides of the drive wheel 62 are respectively engaged with an upper driven wheel 63 and a lower driven wheel 64. A rotating rod 65 is fixedly connected to the surface of the upper driven wheel 63. A rotating tube 66 is fixedly connected inside the lower driven wheel 64. A rotating rod 65 is rotatably connected inside the rotating tube 66. A connecting plate 67 is fixedly connected to the bottom end of both the rotating tube 66 and the rotating rod 65. Stirring blades 68 are fixedly connected to the bottom surface of both connecting plates 67 in a rectangular array.

[0027] During operation, the feeding assembly 3 drives the spiral feeding rod 34 to rotate inside the feeding pipe 31 via the motor 33. The plastic material in the conical discharge trough 36 enters the bottom of the feeding pipe 31 through the connecting pipe 35. The spiral feeding rod 34 vertically lifts the material to the connection between the feed pipe 2 and the feeding pipe 31, and automatically guides it into the mixing cylinder 1 through the feed pipe 2, realizing continuous operation of material conveying and mixing processes.

[0028] Furthermore, the top of the spiral feed rod 34 extends to the connection between the feed pipe 2 and the feed pipe 31, and the outer diameter of the spiral feed rod 34 is in clearance fit with the inner wall of the feed pipe 31.

[0029] During operation, the top of the spiral feed rod 34 extends to the connection between the feed pipe 2 and the feed pipe 31. Its outer diameter maintains a clearance fit with the inner wall of the feed pipe 31. The clearance design between the spiral feed rod 34 and the feed pipe 31 prevents material jamming. At the same time, driven by the motor 33, the spiral feed rod 34 vertically lifts the material fed into the conical feeding trough 36 along the feed pipe 31 to the inlet of the feed pipe 2, realizing continuous material delivery to the mixing tank 1. This structure effectively prevents material blockage and ensures feeding efficiency, reducing the need for manual intervention.

[0030] Furthermore, the rotating tube 66 is rotatably connected to the rotating rod 65 via the lower driven wheel 64. The top and bottom ends of the rotating tube 66 are both shorter than the corresponding ends of the rotating rod 65, and the rotating tube 66 and the rotating rod 65 form a coaxial counter-rotating structure.

[0031] During operation, the rotating tube 66 is rotatably connected to the rotating rod 65 via the lower driven wheel 64. The top and bottom ends of the rotating tube 66 are shorter than the corresponding ends of the rotating rod 65. The rotating tube 66 is driven to rotate counterclockwise by the meshing transmission between the lower driven wheel 64 and the driving wheel 62. At the same time, the rotating rod 65 rotates clockwise via the upper driven wheel 63. During the coaxial and counterclockwise rotation, the misaligned end design of the rotating tube 66 and the rotating rod 65 reduces mechanical interference, so that the two sets of connecting plates 67 drive the stirring blades 68 to form a highly efficient shearing and mixing effect, improving the uniformity and speed of the plastic material mixing.

[0032] Furthermore, the connecting plate 67 is horizontally disposed on the inner bottom wall of the mixing tank 1, and the bottom surface of the connecting plate 67 is vertically fixedly connected to the stirring blade 68, and the side of the stirring blade 68 forms a close contact with the inner wall of the mixing tank 1.

[0033] During operation, the connecting plate 67 is horizontally fixed to the inner bottom wall of the mixing tank 1, and the side of the vertically mounted stirring blade 68 on its bottom surface forms a close contact with the inner wall of the mixing tank 1. When the stirring blade 68 is driven to rotate in the opposite direction by the drive motor 5, the close contact structure between the stirring blade 68 and the tank wall effectively scrapes away the residual material adhering to the inner wall of the mixing tank 1, avoiding local accumulation. At the same time, the rectangular array distribution of the stirring blade 68 combined with the bidirectional rotation generates multidirectional flow, further enhancing the uniformity of material mixing and the mixing coverage, and reducing dead zones.

[0034] Working principle: Plastic material falls through the conical feeding trough 36 and connecting pipe 35 into the bottom of the feeding pipe 31 of the feeding assembly 3. The motor 33 drives the spiral feeding rod 34 to rotate inside the feeding pipe 31, vertically lifting the material to the inlet of the feed pipe 2. The material enters the mixing tank 1 through the feed pipe 2. The drive motor 5 drives the driving wheel 62 of the mixing assembly 6 to rotate. The driving wheel 62 simultaneously engages the upper driven wheel 63 and the lower driven wheel 64 to achieve reverse transmission. The upper driven wheel 63 drives the rotating rod 65 to rotate clockwise, and the lower driven wheel 64 rotates clockwise. The rotating wheel 64 drives the rotating tube 66 to rotate counterclockwise. The rotating tube 66 is sleeved on the outside of the rotating rod 65 to form a coaxial counterclockwise rotation structure. Two sets of connecting plates 67 are fixed to the bottom of the rotating rod 65 and the rotating tube 66, respectively. This drives the rectangular array of stirring blades 68 to form a cross-shearing motion in the mixing tank 1. The sides of the stirring blades 68 are in close contact with the inner wall of the mixing tank 1 to scrape off residual materials. Through bidirectional stirring action, the mixing of materials is accelerated and the uniformity of stirring is improved, ultimately achieving efficient and continuous plastic processing stirring operation.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
