[0047] Among them, two support shafts 3 are rotatably sleeved on the two support blocks 2;

[0048] Among them, a fixing ring 5 is fixedly connected between the two support shafts 3;

[0049] Among them, a mixing tank 4 is rotatably sleeved in the fixing ring 5 through a bearing;

[0050] Among them, the inside of the mixing tank 4 is hollow;

[0051] Among them, a mixing mechanism is installed on the fixing ring 5, and the mixing mechanism includes a material inlet 6, a lid 7, a gear ring 8, a positioning block 9, a first gear 10, a motor 11, a motor base 12, a worm gear 13, a worm 14, an inner fixing column 15, a second gear 16, a rack 17, a sliding block 18, an electric push rod 19, a fixing block 20 and a rotating shaft 21.

[0052] Furthermore, the gear ring 8 is fixedly sleeved on the outer surface of the mixing tank 4;

[0053] Among them, the positioning block 9 is fixedly connected to the outer surface of the fixing ring 5;

[0054] Among them, the rotating shaft 21 is rotatably sleeved on the positioning block 9;

[0055] Among them, the first gear 10 is fixedly connected to one end of the rotating shaft 21;

[0056] Among them, the first gear 10 is meshed with the gear ring 8;

[0057] Among them, the worm gear 13 is fixedly connected to one end of the rotating shaft 21 far from the first gear 10.

[0058] Furthermore, the motor base 12 is fixedly connected to the outer surface of the fixed ring 5;

[0059] Among them, the motor 11 is fixedly connected to the motor base 12;

[0060] Among them, the worm 14 is fixedly connected to the rotating output shaft of the motor 11;

[0061] Among them, the worm 14 is meshed and connected with the worm gear 13;

[0062] Among them, a plurality of inner fixing columns 15 are fixedly connected to the inner wall of the mixing tank 4.

[0063] Furthermore, the material inlet 6 is fixedly connected to the front side surface of the mixing tank 4;

[0064] Among them, the material inlet 6 communicates with the inside of the mixing tank 4;

[0065] Among them, the outer surface of the material inlet 6 is provided with threads, and the lid 7 is threadedly sleeved on the outer surface of the material inlet 6;

[0066] Among them, the second gear 16 is fixedly connected to the left end of the left support shaft 3.

[0067] Furthermore, the electric push rod 19 is fixedly connected to the upper surface of the base 1;

[0068] Among them, the fixed block 20 is fixedly connected to the upper end of the electric push rod 19;

[0069] Among them, the rack 17 is fixedly connected to the lower surface of the fixed block 20.

[0070] Furthermore, the rack 17 is meshed and connected with the second gear 16;

[0073] Furthermore, in this solution, to ensure the mixing effect, the amount of thermoplastic plastic particles loaded into the mixing tank 4 cannot exceed 75% of the capacity of the mixing tank 4.

[0074] Furthermore, pour thermoplastic plastic particles into the mixing tank 4 through the material inlet 6, then cover the lid 7, then start the electric push rod 19. The start of the electric push rod 19 drives the rack 17 to move up and down. The up and down movement of the rack 17 drives the second gear 16 to rotate, and then drives the support shaft 3 and the mixing tank 4 to rotate. Stop when the mixing tank 4 rotates to the horizontal state;

[0075] As described above, when the mixing tank 4 rotates to the horizontal state, the motor 11 is started at this time. The start of the motor 11 drives the worm 14 to rotate, thereby driving the worm gear 13, the rotating shaft 21 and the first gear 10 to rotate. The rotation of the first gear 10 drives the toothed ring 8 to rotate, thereby synchronously driving the mixing tank 4 to rotate. During the rotation of the mixing tank 4, the thermoplastic plastic particles inside are lifted up, and then the thermoplastic plastic particles fall under the action of gravity, thereby realizing the rapid pre-mixing of the thermoplastic plastic particles, with high mixing efficiency, thereby improving the processing efficiency of thermoplastic plastic products, and further increasing the processing efficiency of the pre-mixing device;

[0076] As described above, in this solution, the multiple internal fixing columns 15 can increase the driving of the thermoplastic plastic particles as the mixing tank 4 rotates, thereby increasing the mixing effect of the mixing tank 4 on the thermoplastic plastic particles, and also improving the mixing efficiency of the thermoplastic plastic particles, and further improving the processing efficiency of thermoplastic plastic products.

[0077] Further, after mixing, the electric push rod 19 is started to drive the support shaft 3 and the mixing tank 4 to rotate. When the mixing tank 4 rotates until the material port 6 faces downwards, the lid 7 can be unscrewed at this time. Then, under the action of gravity, the thermoplastic plastic particles in the mixing tank 4 can be poured out downwards, thereby realizing the discharging of the thermoplastic plastic particles. The discharging is convenient and fast, saving manpower and improving the processing efficiency of thermoplastic plastic products at the same time.

[0078] Working principle: When the device is in use, thermoplastic plastic particles are poured into the mixing tank 4 through the material port 6, then the lid 7 is covered, and then the electric push rod 19 is started. The start of the electric push rod 19 drives the rack 17 to move up and down. The up and down movement of the rack 17 drives the second gear 16 to rotate, thereby driving the support shaft 3 and the mixing tank 4 to rotate. When the mixing tank 4 rotates to the horizontal state, it stops;

[0079] As described above, when the mixing tank 4 rotates to the horizontal state, the motor 11 is started at this time. The start of the motor 11 drives the worm 14 to rotate, thereby driving the worm gear 13, the rotating shaft 21 and the first gear 10 to rotate. The rotation of the first gear 10 drives the toothed ring 8 to rotate, thereby synchronously driving the mixing tank 4 to rotate. During the rotation of the mixing tank 4, the thermoplastic plastic particles inside are lifted up, and then the thermoplastic plastic particles fall under the action of gravity, thereby realizing the rapid pre-mixing of the thermoplastic plastic particles, with high mixing efficiency, thereby improving the processing efficiency of thermoplastic plastic products, and further increasing the processing efficiency of the pre-mixing device;

[0080] Further, after mixing, start the electric push rod 19 to drive the support shaft 3 and the mixing tank 4 to rotate. When the mixing tank 4 rotates until the material outlet 6 faces downward, the lid 7 can be unscrewed at this time. Then, under the action of gravity, the thermoplastic plastic particles in the mixing tank 4 can be poured downward, thereby realizing the discharging of the thermoplastic plastic particles. Thus, the discharging is convenient and fast, saving manpower and improving the processing efficiency of thermoplastic plastic products at the same time.
