Specifically, the stirring mechanism is designed inside the tank body, which makes it extremely inconvenient to clean the stirring mechanism during daily use and maintenance.

[0009] Preferably, second spline grooves are provided at lower ends of the first rotating shaft and the third rotating shaft.

[0010] Preferably, a transmission mechanism for realizing the mutual conversion between the cleaning mechanism and the stirring mechanism is installed on the upper surface of the base. The transmission mechanism includes a driving motor, an electric push rod and a transmission shaft. The driving motor is fixedly connected to the upper surface of the base through a connecting block. An upper output end of the driving motor is drivingly connected with a second spline shaft. A first gear is fixedly connected to the side surface of the second spline shaft.

[0015] The beneficial effects of the present invention are as follows: Through the cleaning mechanism and the adjusting mechanism provided in the present invention, when the inside of the preparation tank needs to be cleaned, the connecting rod is pushed towards one side of the adjusting groove through the handle, so that the transmission gear is engaged between the fifth gear and the sixth gear. The fifth gear is driven to rotate by the driving motor, and then the sixth gear is driven to rotate through the transmission gear. Finally, the lifting screw rod is driven to rotate, so that the lifting block threadedly connected to the surface of the lifting screw rod slowly rises until the first spline shaft on the upper part of one side of the lifting block is inserted into the first spline groove at the lower end of the electric push rod. When the first spline shaft just enters the first spline groove, the first gear drives the second gear to rotate through the first transmission belt, so that the third gear rotates. The third gear drives the fourth gear to rotate through the second transmission belt, so that the electric push rod rotates. The electric push rod drives the rotating plate that is rising to rotate 180 degrees through the action of the spline groove and the spline, so that the cleaning mechanism is directly above the preparation tank. At this time, after the lifting block rises to the highest position in the lifting groove, the driving motor stops running, the push switch is triggered and controls the electric push rod to shorten, so that the first spline shaft leaves the first spline groove. Then the driving motor runs in the reverse direction, driving the lifting screw rod to rotate in the reverse direction, so that the lifting block descends, thereby driving the rotating plate and the cleaning mechanism to descend into the preparation tank until the lifting block descends to the lowest part and the handle is released. The transmission gear is pushed outwards through the spring structure, so that the transmission gear is away from the fifth gear and the sixth gear. At this time, the second spline shaft at the upper output end of the driving motor is engaged in the second spline groove on the lower surface of the third rotating shaft. By driving the rotation of the second spline shaft by the driving motor, the third rotating shaft and the rubber brush rotate, achieving the purpose of cleaning the inner wall of the preparation tank, realizing the convenient cleaning of the stirring mechanism inside the preparation tank, improving the maintainability of the equipment, and avoiding the problem of inconvenient cleaning in the daily use of traditional equipment; Through the provided stirring mechanism of the present invention, when highly stirring the polyurethane raw materials inside the preparation tank by the stirring mechanism, the driving motor drives the second spline shaft to rotate, causing the first rotating shaft of the stirring mechanism to rotate. The first rotating shaft drives the first stirring paddle and the connecting plate to rotate. Meanwhile, the connecting plate causes the gear structure to rotate on the inner wall of the preparation tank. At the same time, through the engagement of the gear structure with the tooth blocks on the inner wall of the preparation tank, the gear structure rotates itself, and the rotation direction is opposite to that of the first rotating shaft. The gear structure drives the second stirring paddle to rotate through the second rotating shaft. The polyurethane raw materials are driven from top to bottom for mixing and stirring by the first stirring paddle, and at the same time, the raw materials at the lower part in the preparation tank are driven from bottom to top for mixing and stirring by the reverse rotation of the second stirring paddle, achieving uniform mixing of the polyurethane raw materials in three-dimensional space, improving the mixing effect and the quality of the final product, and solving the problem of poor mixing effect of the traditional stirring mechanism.

[0019] Embodiment 2: The stirring mechanism 5 installed on one side of the lower surface of the rotating plate 406 realizes more uniform mixing and stirring of the polyurethane raw materials; the stirring mechanism 5 includes a first stirring paddle 506 and a second stirring paddle 507. The first stirring paddle 506 is rotatably connected to one side of the lower surface of the rotating plate 406 through a first rotating shaft 501. An upper portion of the side surface of the first rotating shaft 501 is fixedly connected with a connecting plate 503.

[0020] The cleaning mechanism 8 installed on the other side of the lower surface of the rotating plate 406 realizes thorough cleaning inside the preparation tank 301; the cleaning mechanism 8 includes a third rotating shaft 801 and a rubber brush 802. The third rotating shaft 801 is rotatably connected to the other side of the lower surface of the rotating plate 406. The rubber brush 802 is fixedly connected to the side surface of the third rotating shaft 801. Second spline grooves 509 are provided at the lower ends of both the first rotating shaft 501 and the third rotating shaft 801. When the stirring mechanism 5 moves into the preparation tank 301, the second spline shaft 603 is inserted into the second spline groove 509 at the lower end of the first rotating shaft 501, and the driving motor 602 drives the stirring mechanism 5 to operate. When the cleaning mechanism 8 moves into the preparation tank 301, the second spline shaft 603 is inserted into the second spline groove 509 at the lower end of the third rotating shaft 801, realizing the driving motor 602 to drive the cleaning mechanism 8 to operate.

[0021] Embodiment 3: A transmission mechanism 6 for realizing the mutual conversion between the cleaning mechanism 8 and the stirring mechanism 5 is installed on the upper surface of the base 1. The transmission mechanism 6 includes a driving motor 602, an electric push rod 611 and a transmission shaft 607. The driving motor 602 is fixedly connected to the upper surface of the base 1 through a connecting block 601. The upper output end of the driving motor 602 is drivingly connected with a second spline shaft 603. A first gear 604 is fixedly connected to the side surface of the second spline shaft 603. The transmission shaft 607 is rotatably connected to the inside of the bracket 2. A second gear 605 is fixedly connected to the lower end of the transmission shaft 607. The second gear 605 and the first gear 604 are drivingly connected to each other through a first transmission belt 606. A third gear 608 is fixedly connected to the upper end of the transmission shaft 607. The fixed end of the electric push rod 611 is rotatably connected to the upper inner surface of the bracket 2 through a fourth gear 609. The third gear 608 and the fourth gear 609 are drivingly connected to each other through a second transmission belt 610. A first spline groove 612 is opened at the lower end of the electric push rod 611. A push switch 613 is installed on the upper inner surface of the lifting groove 402 opened inside the column 401. The electric push rod 611 is electrically connected to an external power supply through the push switch 613. During the operation of the driving motor 602, the first gear 604 drives the second gear 605 to continuously rotate through the first transmission belt 606, so that the transmission shaft 607 continuously rotates. Finally, the third gear 608 drives the fourth gear 609 and the electric push rod 611 to continuously rotate through the second transmission belt 610. When adjusting the positions of the stirring mechanism 5 and the cleaning mechanism 8, when the first spline shaft 405 is inserted into the first spline groove 612 at the lower end of the electric push rod 611, it can drive the stirring mechanism 5 and the cleaning mechanism 8 on both sides of the lower surface of the rotating plate 406 to perform position conversion.

[0022] Embodiment 4: An adjusting mechanism 7 for driving the lifting mechanism 4 to control the lifting of the stirring mechanism 5 and the cleaning mechanism 8 is installed at the lower part of the driving motor 602. The adjusting mechanism 7 includes a transmission gear 706, a fifth gear 705, and a sixth gear 707. The transmission gear 706 is rotatably connected to the lower surface of the connecting rod 704. The fifth gear 705 is drivingly connected to the lower output end of the driving motor 602. The sixth gear 707 is fixedly connected to the lower end of the lifting screw rod 403. An adjusting groove 701 is formed in the upper surface of the base 1. An adjusting rod 702 is fixedly connected inside the adjusting groove 701. The connecting rod 704 is slidably connected to the surface of the adjusting rod 702. A handle 703 is fixedly connected to one side of the upper surface of the connecting rod 704. A spring structure 708 is provided between one side of the adjusting rod 702 and the inner wall of the adjusting groove 701. When the inside of the preparation tank 301 needs to be cleaned, the connecting rod 704 is squeezed toward one side through the handle 703, so that the transmission gear 706 is engaged between the fifth gear 705 and the sixth gear 707, realizing that the fifth gear 705 drives the sixth gear 707 and the lifting screw rod 403 to rotate through the transmission gear 706, so that the lifting block 404 drives the stirring mechanism 5 and the cleaning mechanism 8 to rise synchronously. When the first spline shaft 405 on the upper surface of the rotating plate 406 is inserted into the first spline groove 612 of the electric push rod 611 during the rising process of the lifting block 404, the continuously rotating electric push rod 611 drives the first spline shaft 405 and the rotating plate 406 to rotate, so that the rotating plate 406 rotates to realize the position conversion of the stirring mechanism 5 and the cleaning mechanism 8. Until the pressing switch 613 is squeezed and triggered after the lifting block 404 rises to the highest position, at this time the rotating plate 406 rotates 180 degrees, the driving motor 602 stops running, and at the same time controls the electric push rod 611 to shorten, so that the first spline shaft 405 leaves the first spline groove 612. After the first spline shaft 405 completely leaves the first spline groove 612, the driving motor 602 runs in reverse, so that the lifting screw rod 403 rotates in reverse, driving the lifting block 404 to descend. When the pressing switch 613 loses the squeezing force during the descending process of the lifting block 404, it resets itself, and the electric push rod 611 slowly extends to the initial position. After the lifting block 404 descends to the lowest part, at this time the cleaning mechanism 8 is inside the preparation tank 301. Release the handle 703, and the transmission gear 706 is pulled out and away from the fifth gear 705 and the sixth gear 707 through the restoring elastic force of the spring structure 708. At this time, the second spline shaft 603 is engaged in the second spline groove 509 at the lower end of the third rotating shaft 801 of the cleaning mechanism 8, driving the cleaning mechanism 8 to rotate, and cleaning the inner wall of the preparation tank 301 through the rubber brush 802.

[0023] During use, add the polyurethane raw materials into the preparation tank 301, start the drive motor 602, and drive the first gear 604 at the upper output end and the fifth gear 705 at the lower output end to rotate synchronously. At this time, the stirring mechanism 5 is inside the preparation tank 301. The second spline shaft 603 at the upper output end of the drive motor 602 is inserted into the second spline groove 509 at the lower end of the first rotating shaft 501 of the stirring mechanism 5. Drive the first rotating shaft 501 to rotate through the drive motor 602, so that the connecting plate 503 drives the gear structure 504 and the second rotating shaft 505 to rotate, and the first rotating shaft 501 and the second rotating shaft 505 rotate in opposite directions. The first rotating shaft 501 drives the first stirring paddle 506 to perform forward stirring, so that the polyurethane raw materials are stirred and mixed from top to bottom. The second rotating shaft 505 drives the second stirring paddle 507 to perform reverse stirring, so that the polyurethane raw materials are stirred and mixed from bottom to top, realizing the uniform mixing of the polyurethane raw materials in three-dimensional space. After the mixing and stirring are completed, control the discharge of the materials through the valve 302. When the inside of the preparation tank 301 needs to be cleaned, push the connecting rod 704 to one side through the handle 703, so that the transmission gear 706 is stuck between the fifth gear 705 and the sixth gear 707. At this time, the fifth gear 705 is driven to rotate through the drive motor 602, and the sixth gear 707 is driven to rotate through the transmission gear 706, so that the lifting screw rod 403 rotates. The lifting screw rod 403 drives the lifting block 404 to rise, so that the rotating plate 406 on the upper side of one side of the lifting block 404, the stirring mechanism 5 and the cleaning mechanism 8 rise. Since the first spline shaft 405 has a specific length, during the process of the first spline shaft 405 rising with the lifting block 404, when the first spline shaft 405 contacts the first spline groove 612 at the lower end of the electric push rod 611, at this time the stirring mechanism 5 completely leaves the inside of the preparation tank 301. At the same time, the rotating plate 406 rotates with the rotation of the first spline shaft 405. When the lifting block 404 rises to the limit inside the lifting groove 402 and triggers the pressure switch 613, at this time the rotating plate 406 is just driven by the first spline shaft 405 and rotates 180 degrees. After the pressure switch 613 is triggered, first control the electric push rod 611 to shorten so that the first spline groove 612 rises and leaves the surface of the first spline shaft 405. After the electric push rod 611 is shortened to the limit, the first spline groove 612 completely leaves the first spline shaft 405. Then the drive motor 602 starts in reverse, and then control the cleaning mechanism 8 just above the preparation tank 301 to slowly move towards the inside of the preparation tank 301. By controlling the length of the first spline shaft 405, the rotation angle of the rotating plate 406 can be controlled. Controlling the rotating plate 406 to rotate 180 degrees can realize that the cleaning mechanism 8 is just above the preparation tank 301. Drive the transmission gear 706, the sixth gear 707 and the lifting screw rod 403 to rotate in the reverse direction through the fifth gear 705, so that the lifting block 404 drives the rotating plate 406, the stirring mechanism 5 and the cleaning mechanism 8 to descend. At this time, the cleaning mechanism 8 is just above the preparation tank 301.Until the cleaning mechanism 8 completely enters the interior of the preparation tank 301 and the second spline shaft 603 at the upper output end of the driving motor 602 is clamped into the second spline groove 509 at the lower end of the third rotating shaft 801 of the cleaning mechanism 8, release the handle 703, and drive the connecting rod 704 and the transmission gear 706 to slide towards the other side through the restoring elastic force of the spring structure 708, so that the transmission gear 706 is away from the fifth gear 705 and the sixth gear 707. At this time, the height of the cleaning mechanism 8 does not change. At the same time, the driving motor 602 drives the third rotating shaft 801 to rotate through the second spline shaft 603, so that the rubber brush 802 rotates to realize the cleaning of the inner wall of the preparation tank 301.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
