[0036] Compared with the prior art, the three-dimensional mixing device provided by the embodiment of the application is connected by the round belt 9 between the fixed disc 7 and the driving disc 8, and the round belt 9 is tightened by the tension pulley 10, so that the base 5 and the driving disc 8 rotate around the main shaft 2 when the main shaft 2 drives the rotary arm 4 to rotate, which drives the driving disc 8 to rotate, that is, the base 5 rotates, so that the rotation of the main shaft 2 and the rotation of the base 5 constitute the revolution and rotation of the material cylinder when the material cylinder is clamped between the cover 6 and the base 5, thus realizing mixing and saving the power source, making the structure simple and efficient, and improving the practicability of the device.

Specifically, the moving direction of the cover body 6 relative to the base 12 is along the axial direction of the base 5, and the cover body 6 clamps or releases the material cylinder between the cover body 6 and the base 5 through the movement control. Under the support of the rotating seat 11 and the base 12, the axial direction of the cover body 6 coincides with the axial direction of the base 5.

[0038] As the preferred technical scheme of the embodiment, the rotating arm 4 is provided with a rotating seat 11, the rotating seat 11 is provided with a base 12, and the cover body 6 is movably connected to the base 12. Specifically, the moving direction of the cover body 6 relative to the base 12 is along the axial direction of the base 5, and the cover body 6 clamps or releases the material cylinder between the cover body 6 and the base 5 through the movement control. Under the support of the rotating seat 11 and the base 12, the axial direction of the cover body 6 coincides with the axial direction of the base 5.

[0039] As the preferred technical scheme of the embodiment, the rotating arm 4 is provided with a rotating seat 11, the rotating seat 11 is provided with a base 12, and the cover body 6 is movably connected to the base 12. Specifically, the moving direction of the cover body 6 relative to the base 12 is along the axial direction of the base 5, and the cover body 6 clamps or releases the material cylinder between the cover body 6 and the base 5 through the movement control. Under the support of the rotating seat 11 and the base 12, the axial direction of the cover body 6 coincides with the axial direction of the base 5.

[0040] As the preferred technical scheme of the embodiment, the rotating seat 11 is a rotating cylinder 16, and the base 12 is an extending cylinder 17. Specifically, the rotating cylinder 16 and the extending cylinder 17 are both controlled by a pneumatic system. A slip ring 31 is sleeved outside the main shaft 2 and fixedly connected with the fixed disc 7. Two groups of input air valves are arranged on the slip ring 31. Two groups of relay air valves are arranged on the rotating arm 4. One group of receiving air valves is arranged on the rotating cylinder 16 and the extending cylinder 17. The input air valves and the relay air valves are connected through a plurality of channels arranged in the slip ring 31, and are connected in operation when the rotating arm 4 is stationary at the vertical position. The relay air valves are connected with the receiving air valves through external pipelines. Thus, when the rotating arm 4 rotates, the pneumatic system does not work, and the pipelines between the relay air valves and the receiving air valves rotate with the rotating arm 4, so that the pipeline winding problem can be avoided.

[0041] In the second embodiment of the application, the base 5 is provided with a groove 18 near one end of the cover 6. A top plate 19 is movably arranged in the groove 18. The movement of the top plate 19 is linked with the rolling of the round belt 9 on the driving disc 8 and is periodic. The cover 6 is movably provided with a cover plate 20. Specifically, the size of the groove 18 matches the size of the bottom of the material cylinder. The top plate 19 moves axially in the groove 18. The movement of the top plate 19 is linked with the rolling of the round belt 9, so that the movement of the top plate 19 occurs in the rotating process of the rotating arm 4, that is, in the above combined mixing process of revolution and rotation. Thus, the movement of the top plate 19 increases the intermittent reciprocating movement of the material cylinder along the axial direction, that is, another direction of mixing action, so as to further improve the mixing effect and the mixing efficiency. The cover 6 is preferably a circular cover. The cover plate 20 is embedded in the cover 6 and coaxially arranged. One side of the cover plate 20 inside the cover 6 is connected with the inside of the cover 6 through a spring. The spring keeps pushing the cover plate 20 outward. The cover plate 20 is used to abut against one end of the opening of the material cylinder in actual use. The base 5 and the cover 6 cooperate to clamp the material cylinder. Specifically, the top plate 19 and the cover plate 20 cooperate to clamp the material cylinder, and the groove 18 limits the material cylinder. At this time, the intermittent movement of the top plate 19 cooperates with the elastic movement of the cover plate 20 to keep clamping and controlling the material cylinder.

[0042] As the preferred technical scheme of the embodiment, the top plate 19 is provided with a guide column 21 away from the cover 6, the guide column 21 is provided with an inclined sliding groove 22, the inclined sliding groove 22 is movably connected with a sliding pin 23, the sliding pin 23 is fixedly provided with a linkage rod 24, one end of the linkage rod 24 is movably penetrated into a ring-shaped recess groove on the sidewall of the driving disc 8 for embedding the round belt 9, specifically, the axial direction of the guide column 21 is parallel to the axial direction of the base 5; the inclined sliding groove 22 is provided with an upper end closer to the position where the linkage rod 24 penetrates the driving disc 8; when the sliding pin 23 is at the upper end of the inclined sliding groove 22, the linkage rod 24 is the longest to protrude out of the sidewall of the driving disc 8, and the longest is preferably 10-20 mm; when the sliding pin 23 is at the lower end of the inclined sliding groove 22, the linkage rod 24 is completely received in the sidewall of the driving disc 8; when the cover 6 is at the clamping position, i.e. the base 5 is directly below the cover 6, at this time, the radial direction of the linkage rod 24 is just parallel to the direction of the driven end of the main shaft 2, thereby, when the rotating arm 4 rotates to the first time close to the horizontal position, the protruding end of the linkage rod 24 starts to be retracted under the extrusion of the round belt 9 to drive the guide column 21 to move the top plate 19 out of the recess 18, so that the top plate 19 cooperates with the cover plate 20 to control the lateral movement of the material cylinder in the horizontal state, then, the linkage rod 24 is continuously extruded by the round belt 9, when the rotating arm 4 rotates to the second time close to the horizontal position, the end of the linkage rod 24 blocked by the round belt 9 gradually leaves the round belt 9, then under the elastic force of the cover plate 20, the cover plate 20 cooperates with the top plate 19 to control the lateral movement of the material cylinder in the horizontal state again, so that the top plate 19 is retracted in the recess 18, and then the linkage rod 24 is re-elongated to the outside of the sidewall of the driving disc 8, so as to realize the axial reciprocating movement of the material cylinder by the rotating arm 4 every time close to the horizontal state.

[0043] In the third embodiment, the rotating seat 11 is provided with a switching shaft 25 rotating synchronously with the base 12 and a power ring 26 driving the switching shaft 25 to move axially, the fixed disc 7 is connected with a butt joint shaft 27 coaxial with the switching shaft 25 and rotatingly connected on the rotating arm 4 through a pulley assembly, one end of the switching shaft 25 is provided with a clutch assembly for butt joint with the butt joint shaft 27, and the other end is provided with a linkage assembly linked with the cover 6. In the first embodiment, the rotating cylinder 16 drives the telescopic cylinder 17 to rotate, so that the pneumatic pipeline on the telescopic cylinder 17 is repeatedly twisted and pulled in actual use, which is easy to damage, and the present embodiment is proposed to solve.The switching shaft 25 can rotate and move axially; the power ring 26 can be preferably controlled by air, and the rotating seat 11 is provided with a cavity matched with the power ring 26, and the two ends of the cavity are respectively provided with receiving air valves, and the receiving air valves are switched to receive and release air to control the movement of the power ring 26, thereby controlling the axial movement of the switching shaft 25, and not affecting the rotation of the switching shaft 25; the power ring 26 can also be preferably controlled by magnetic force, which is not described herein; the pulley assembly includes a fixed pulley 32 coaxially fixed opposite the fixed disc 7, a linkage pulley 33 coaxially fixedly connected with the docking shaft 27, and a synchronous belt 34 connected between the fixed pulley 32 and the linkage pulley 33, and the fixed pulley 32 is actually fixedly sleeved outside the slip ring 31, so that when the rotating arm 4 rotates, the linkage pulley 33 rotates around the fixed pulley 32 to make the linkage pulley 33 rotate on the rotating arm 4, and the transmission ratio of the fixed pulley 32 and the linkage pulley 33 is 1:1, so that under the linkage of the pulley assembly, the angle of rotation of the rotating arm 4 is consistent with the angle of rotation of the docking shaft 27 on the rotating arm 4, and the rotating arm 4 can be rotated to make one end of the cover body 6 face upward, and the base 12 is linked to rotate to make the cover body 6 rotate toward the center of the rotating arm 4, that is, the cover body 6 rotates downward, and the rotating arm 4 is rotated to make one end of the cover body 6 face downward, and the base 12 is linked to rotate to make the cover body 6 rotate away from the center of the rotating arm 4, that is, the cover body 6 also just rotates downward; when the switching shaft 25 moves axially to approach the docking shaft 27, the switching shaft 25 can be connected with the docking shaft 27 through the clutch assembly to rotate synchronously, at this time, the switching shaft 25 also links the cover body 6 to retract through the linkage assembly, and when the switching shaft 25 moves axially away from the docking shaft 27, the clutch assembly is disconnected, at this time, the switching shaft 25 links the cover body 6 to extend through the linkage assembly; the cover body 6 moves with the switching shaft 25 through the linkage assembly, and just corresponds to the cover body 6 approaching the base 5 to clamp the material cylinder, the clutch assembly is disconnected, so that the subsequent rotation of the rotating arm 4 will not link the base 12 to rotate, and the cover body 6 is away from the base 5 to release the material cylinder, and then needs to be cleaned, the clutch assembly is connected, so that the subsequent rotation of the rotating arm 4 links the base 12 to rotate, so that the cover body 6 is automatically flipped relative to the rotating arm 4 to switch to the dust removal position, it can be seen that the above linkage structure not only saves the power source for driving the rotation of the base 12, but also only needs to set the receiving air valve on the rotating seat 11 to control the movement of the power ring 26, and the rotating seat 11 is fixed relative to the rotating arm 4, so that the pipeline between the relay air valve and the receiving air valve is fixed relative to the rotating arm 4, and will not be twisted and pulled.

[0044] As a preferred technical solution of the embodiment, the clutch assembly includes two docking blocks 28 coaxially arranged at the proximal ends of the switching shaft 25 and the docking shaft 27, and the two docking blocks 28 are tightly fitted to rotate synchronously, specifically, the adjacent surfaces of the two docking blocks 28 are provided with star patterns or friction layers matched with each other, which can transmit torque to rotate synchronously when tightly fitted, and have no effect on each other when separated.

[0045] As a preferred technical scheme of the embodiment, the linkage assembly comprises a telescopic rod 29 movably arranged on the base 12 and a connecting rod 30 hingedly connected to one end of the switching shaft 25, one end of the telescopic rod 29 movably penetrates the base 12 and is fixedly connected with the cover 6, the other end of the connecting rod 30 is hingedly connected with the telescopic rod 29, specifically, the telescopic rod 29 controls the movement of the cover 6 relative to the base 12, the connecting rod 30 is obliquely arranged, and the connecting rod 30 synchronously rotates the base 12 and the switching shaft 25; in actual use, when the switching shaft 25 approaches the base 12, the connecting rod 30 is pushed, the connecting rod 30 pushes the telescopic rod 29, and the telescopic rod 29 drives the cover 6 to elongate in the direction away from the base 12, conversely, when the switching shaft 25 is away from the base 12, the cover 6 is retracted in the direction approaching the base 12.

[0046] The above has described certain exemplary embodiments of the present application by way of illustration only, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application.
