The mixing tank is located inside the water bath, and a feed hopper is located at the top. By employing the above technical solution, this invention mixes ground raw materials with materials that do not require grinding, ensuring thorough mixing and facilitating further processing. The device uses simple snap-fit, threaded, and screw-fixed connections for easy disassembly and cleaning.

[0003] However, the stirring device in this patent cannot stir the chocolate syrup at different heights in the mixing tank, resulting in uneven stirring. Utility Model Content

[0004] The purpose of this invention is to provide a sedimentation-preventing lifting stirring mechanism for chocolate production, which has the advantages of vertical lifting and uniform stirring, and solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sedimentation-preventing lifting stirring mechanism for chocolate production includes a stirring tank and a tank lid. The bottom of the tank lid is equipped with a first motor and a second motor. The output end of the first motor is connected to a small wheel. A mounting plate is also provided at the bottom of the tank lid. A large wheel is rotatably connected to the outer wall of the mounting plate via bearings. The small wheel is connected to the large wheel via a belt. The output end of the second motor is equipped with a second bevel gear, which meshes with a first bevel gear. A screw is connected to the bottom of the first bevel gear. The bottom surface of the large wheel is movably connected to a rotating circular plate via a bushing. The screw is threadedly engaged with an internally threaded sleeve. The bottom end of the internally threaded sleeve is connected to the center of the rotating circular plate via a connecting bearing. The bottom of the rotating circular plate is equipped with a stirring plate that fits against the bottom and side walls of the stirring tank.

[0007] Preferably, the first motor and the second motor are respectively connected to the bucket lid through a mounting plate, and a mounting disc is fixedly connected to the center of the two mounting plates.

[0008] Preferably, the bushings are symmetrically distributed on the bottom surface of the large disc, and the top of the rotating disc is provided with a shaft that passes through the bushing, and the bushings and shafts form a sliding rotary pair.

[0009] Preferably, the bottom of the mounting plate is provided with a limiting plate, the limiting plate is U-shaped and has a circular groove, the internal threaded sleeve passes through the circular groove and is provided with a limiting strip, and the inner wall of the circular groove is provided with a corresponding limiting groove and slidingly engaged with the limiting strip.

[0010] Preferably, the length of the threaded section between the internal threaded sleeve and the screw is not less than 2 / 3 of the height of the mixing tank.

[0011] Preferably, the connection between the screw and the mounting plate is not threaded, and the screw and the mounting plate are rotatably connected.

[0012] Preferably, the connecting bearing is a double-direction thrust ball bearing.

[0013] Preferably, the diameter ratio of the large wheel to the small wheel is 3:1 to 5:1.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, a first motor drives a small disc to rotate, which in turn drives a large disc to rotate at a higher speed via a belt. The large disc drives a bushing to rotate, which in turn drives a shaft to rotate. The shaft then drives a rotating disc to rotate, which in turn drives a stirring plate to rotate, thus stirring the chocolate mixture in the mixing tank. A second motor drives a screw to rotate via a first and a second bevel gear. This screw drives an internal threaded sleeve to move vertically up and down. When the internal threaded sleeve descends, it drives the rotating disc and stirring plate to descend and stir the chocolate mixture at the bottom of the mixing tank. When the internal threaded sleeve rises, it drives the rotating disc and stirring plate to rise and stir the chocolate mixture at the top of the mixing tank. The first and second motors can operate simultaneously, meaning that rotational stirring and vertical lifting can occur concurrently without interference. This eliminates the need to pause the rotational stirring motion and adjust the stirring height, saving downtime and improving stirring efficiency. Attached Figure Description

[0021] 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 protection scope of the present utility model.

[0022] To address the problem of uneven mixing inside the container due to the inability to vertically lift and lower the container in existing technologies, the following technical solution is provided. Please refer to [link / reference needed]. Figure 1-4 ;

[0023] A sedimentation-preventing lifting stirring mechanism for chocolate production includes a stirring tank 1 and a tank cover 2. A first motor 3 and a second motor 4 are installed on the bottom surface of the tank cover 2. The first motor 3 and the second motor 4 are respectively connected to the tank cover 2 through a mounting plate 5. A mounting plate 6 is fixedly connected in the middle of the two mounting plates 5. The mounting plate 6 is fixed during the operation of the entire device.

[0024] A large wheel 7 is rotatably connected to the outer wall of the mounting plate 6 via bearings. The output shaft of the first motor 3 is vertically downward and connected to the small wheel 8. The large wheel 7 and the small wheel 8 are connected by a belt 9. The diameter ratio of the large wheel 7 to the small wheel 8 is 3:1-5:1.

[0025] Two bushings 17 are provided on the bottom surface of the large wheel 7. The bushings 17 are located on both sides of the screw 10. Two shafts 18 are fixed on the top surface of the rotating circular plate 16. The shafts 18 and the bushings 17 are both arranged perpendicularly. The shafts 18 are inserted into the corresponding bushings 17 and are slidably connected to the bushings 17.

[0026] A stirring plate 19 is provided on the bottom surface of the rotating circular plate 16. The bottom of the stirring plate 19 is in contact with the inner bottom surface of the mixing tank 1, and the outer end of the stirring plate 19 is in contact with the inner side wall of the mixing tank 1, so that the stirring plate 19 can scrape off the sediment on the bottom surface and the adhering substances on the side wall during the rotation and stirring process.

[0027] Specifically, the first motor 3 drives the small wheel 8 to rotate, and the small wheel 8 drives the large wheel 7 to rotate at a higher speed through the belt 9. The large wheel 7 drives the bushing 17 to rotate, and the bushing 17 drives the shaft 18 to rotate accordingly. The shaft 18 drives the rotating disc 16 to rotate, which in turn drives the stirring plate 19 to rotate to stir the chocolate paste in the mixing tank 1.

[0028] A screw 10 is provided below the mounting plate 6. The top of the screw 10 passes through the mounting plate 6 and is connected to the first bevel gear 11. The output shaft of the second motor 4 extends horizontally and passes through the mounting plate 5 and is connected to the second bevel gear 12. The first bevel gear 11 and the second bevel gear 12 mesh with each other. There is no thread at the connection between the screw 10 and the mounting plate 6. The screw 10 is rotatably connected to the mounting plate 6.

[0029] The bottom of the mounting plate 6 is provided with a limiting plate 13, which has a "U" shaped structure. The top of the limiting plate 13 is fixedly connected to the bottom surface of the mounting plate 6. A circular groove 21 for the internal threaded sleeve 14 to pass through is provided at the center of the bottom of the limiting plate 13. The internal threaded sleeve 14 is vertically arranged. The upper part of the internal threaded sleeve 14 is threadedly engaged with the screw 10. The bottom end of the internal threaded sleeve 14 is connected to the center of the rotating circular plate 16 through the connecting bearing 15.

[0030] The length of the threaded section between the internal threaded sleeve 14 and the screw 10 is not less than 2 / 3 of the height of the mixing tank 1, and the connecting bearing 15 adopts a double-direction thrust ball bearing.

[0031] A limiting strip 20 is provided on the outer wall of the internal threaded sleeve 14, and a corresponding limiting groove 22 is provided on the inner wall of the circular groove 21, so that the internal threaded sleeve 14 can move vertically relative to the limiting plate 13.

[0032] Specifically, the second motor 4 drives the screw 10 to rotate through the first bevel gear 11 and the second bevel gear 12, so that the screw 10 drives the internal threaded sleeve 14 to move vertically up and down. When the internal threaded sleeve 14 descends, it drives the rotating disc 16 and the stirring plate 19 to descend and stir the chocolate paste at the bottom of the mixing tank 1. When the internal threaded sleeve 14 rises, it drives the rotating disc 16 and the stirring plate 19 to rise and stir the chocolate paste at the top of the mixing tank 1.

[0033] In summary, the function of the first motor 3 is to drive the rotating disc 16 and the stirring plate 19 to rotate on a certain plane, thereby achieving the stirring effect. The function of the second motor 4 is to drive the internal threaded sleeve 14 to rise and fall vertically, thereby causing the rotating disc 16 and the stirring plate 19 to rise and fall vertically, thus realizing the stirring of chocolate paste at different heights in the mixing tank 1, making the stirring more uniform.

[0034] It is worth noting that the first motor 3 and the second motor 4 can operate simultaneously, that is, the rotary stirring and vertical lifting can be carried out at the same time without interference. There is no need to stop the rotary stirring motion and then adjust the stirring height, saving downtime and thus improving stirring efficiency.

[0035] Working principle: The first motor 3 drives the small wheel 8 to rotate, and the small wheel 8 drives the large wheel 7 to rotate at a higher speed through the belt 9. The large wheel 7 drives the bushing 17 to rotate, and the bushing 17 drives the shaft 18 to rotate accordingly. The shaft 18 drives the rotating disc 16 to rotate, which in turn drives the stirring plate 19 to rotate and stir the chocolate paste in the mixing tank 1. The second motor 4 drives the screw 10 to rotate through the first bevel gear 11 and the second bevel gear 12. The screw 10 drives the internal threaded sleeve 14 to move vertically up and down. When the internal threaded sleeve 14 descends, it drives the rotating disc 16 and the stirring plate 19 to descend and stir the chocolate paste at the bottom of the mixing tank 1. When the internal threaded sleeve 14 rises, it drives the rotating disc 16 and the stirring plate 19 to rise and stir the chocolate paste at the top of the mixing tank 1.
