Detailed Implementation

[0013] like Figures 1-3As shown, this utility model proposes a mixing auxiliary device for memory foam production, including a motor 1, a mixing frame 2, and a docking assembly 3 fixed between the motor 1 and the mixing frame 2; the motor 1, the docking assembly 3, and the mixing frame 2 are connected as a whole from top to bottom; the motor 1 is a servo motor or a stepper motor. The docking component 3 includes; Link 31, the top end of which is fixed to the output end of motor 1; Inner rod 32, the bottom end of which is fixed to the stirring frame 2; The rod cavity 33 is centrally located at the top of the inner rod 32, and the connecting rod 31 extends into the rod cavity 33 for movement; the rod cavity 33 is formed by a recess in the inner rod 32, which is centrally located at the top of the inner rod 32 and faces downward, and the connecting rod 31 moves downward into the rod cavity 33 from the top of the rod cavity 33. Guide assembly 34 is disposed between connecting rod 31 and rod cavity 33; when connecting rod 31 rotates, it drives inner rod 32 to rotate through guide assembly 34. A sturdy sleeve 35 is provided around the inner rod 32; The traction component 36 is located between the inner rod 32 and the sleeve 35. When the inner rod 32 rotates, the traction component 36 supports and drives the inner rod 32 to move up and down.

[0014] like Figure 3 As shown, when the mixing auxiliary device is used, the connecting rod 31 penetrates into the mixing tank from top to bottom, and the top of the sleeve 35 is fixed to the top of the tank. When the motor 1 is running, the output end of the motor 1 drives the connecting rod 31 to rotate, and the connecting rod 31 extends into the rod cavity 33 and moves up and down. Under the action of the guide component 34, it drives the inner rod 32 to rotate synchronously. At the same time, the traction component 36 supports and drives the inner rod 32 to move up and down. The bottom end of the inner rod 32 is fixed to the mixing frame 2. In this way, the mixing frame 2 can be rotated synchronously while reciprocating up and down.

[0015] The traction assembly 36 is provided in two sets, which are distributed vertically; the stability during movement is improved by adding a support for the inner rod 32.

[0016] The specific structure of the traction component 36 is shown below: The traction assembly 36 includes a protrusion 361 fixed to the outside of the inner rod 32, an annular groove 362 located inside the sleeve 35, a first universal ball 363 fixed to the outside of the protrusion 361, and a first ball groove 364 located inside the annular groove 362. The protrusion 361 extends into the annular groove 362, and the first wear-resistant layer is fixedly attached to the first ball groove 364. The rolling end of the first universal ball 363 extends into the first ball groove 364 and is attached to the first wear-resistant layer. The annular groove 362 is inclined from top to bottom. The first wear-resistant layer (MoS2) is a molybdenum disulfide coating, which is wear-resistant and has a low coefficient of friction. When the inner rod 32 rotates, under the guidance of the protrusion 361 extending into the annular groove 362, the protrusion 361 moves in annular motion within the annular groove 362. As the inner rod 32 continues to rotate, the protrusion 361 performs reciprocating up-and-down displacement, thereby driving the inner rod 32 to rotate and move up and down synchronously, which in turn drives the stirring frame 2 to move. The protrusion 361 rolls and moves smoothly by adhering to the first wear-resistant layer of the first ball groove 364 through the first universal ball 363. Among them, multiple sets of first universal ball bearings 363 and first ball grooves 364 are provided in a one-to-one correspondence; when the first universal ball bearings 363 extend into the first ball grooves 364 and are in contact with the first wear-resistant layer, the protrusions 361 do not contact the annular rail grooves 362 and the sleeves 35. like Figure 2 As shown, multiple sets of one-to-one corresponding first universal ball bearings 363 and first ball grooves 364 are set to provide moving support for the protrusion 361, which can provide better stability. The rolling end of the first universal ball bearing 363 is inserted into the first ball groove 364 and fits against the first wear-resistant layer to provide support for the protrusion 361, so as to prevent the protrusion 361 from generating moving resistance after contacting the annular rail groove 362 and the sleeve 35, thus ensuring the smoothness of the movement of the protrusion 361.

[0017] The specific structure of the guide component 34 is shown below: The guide assembly 34 includes a vertical groove 341 disposed in the rod cavity 33, a sliding block 342 fixed to the outside of the connecting rod 31, a second universal ball 343 fixed to the outside of the sliding block 342, and a second ball groove 344 disposed on the vertical groove 341. The sliding block 342 extends into the vertical groove 341 and moves. The vertical groove 341 and the sliding block 342 are provided in multiple sets and are evenly distributed on the outside of the connecting rod 31. The second wear-resistant layer is attached and fixed in the second ball groove 344. The rolling end of the second universal ball 343 extends into the second ball groove 344 and is attached to the second wear-resistant layer. The second wear-resistant layer (MoS2) is a molybdenum disulfide coating, which is wear-resistant and has a low coefficient of friction. Multiple sets of vertical grooves 341 are evenly arranged in a ring in the rod cavity 33. Each set of vertical grooves 341 is provided with a sliding block 342. The vertical grooves 341 are connected to the top of the connecting rod 31 so that the sliding block 342 can extend into it. The rolling end of the second universal ball 343 extends into and fits against the second ball groove 344 to provide smooth and stable vertical displacement of the upper and lower connecting rods 31. When the connecting rod 31 rotates, the sliding block 342 and the second universal ball 343 can apply force to drive the inner rod 32 to rotate synchronously. Among them, the second universal ball bearing 343 and the second ball groove 344 are provided in multiple sets and are evenly distributed between the vertical groove 341 and the sliding block 342; the overall support balance of the sliding block 342 is improved, so as to further improve the stability of the guide.
