[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 - 5 , a mixing and stirring device for chemical raw materials, comprising:

[0027] A working box 1, a feeding channel 2 is installed on the left side of the working box 1, and a sealing door 3 is installed on the right side of the working box 1;

[0028] A working mechanism, which is located in the inner cavity and at the top of the working box 1 and is used for mixing and stirring raw materials. The working mechanism includes a lifting component, a stirring component and a mixing component. The lifting component is located at the top of the working box 1 and is used for lifting the stirring component. The stirring component is located at the bottom of the lifting component and is used for stirring raw materials. The mixing component is located in the inner cavity of the working box 1 and is used for mixing raw materials.

[0029] The lifting component includes a first motor 4 and a connecting seat 5 installed on the top of the working box 1. A bidirectional lead screw 6 is rotatably connected between the first motor 4 and the connecting seat 5. The output shaft of the first motor 4 is fixedly connected to the bidirectional lead screw 6 through a coupling. A first moving block 7 is threadedly connected to the outer ring of the bidirectional lead screw 6. The top of the first moving block 7 is hinged to a lifting plate 8. The lifting plates 8 are rotatably connected through a pin shaft. The top of the lifting plate 8 is hinged to a second moving block 9. A top plate 10 is slidably connected to the top of the second moving block 9. A limiting component is also installed between the second moving block 9 and the top plate 10.

[0030] The limiting component includes a chute 11 opened at the bottom of the top plate 10. A slider 12 is fixedly connected to the top of the second moving block 9. The slider 12 is slidably connected to the inner cavity of the chute 11.

[0031] The stirring component includes a second motor 13 installed in the inner cavity of the top plate 10. A second rotating shaft 14 is installed at the bottom of the second motor 13. The output shaft of the second motor 13 is fixedly connected to the second rotating shaft 14 through a coupling. A stirring roller 15 is installed at the bottom of the second rotating shaft 14. The stirring rollers 15 are distributed in a multi-group circumferential array.

[0032] The mixing component includes a mixing box 16 installed on the back of the working box 1. A connecting shaft 17 is installed on the front of the mixing box 16. A mixing roller 18 is installed on the outer ring of the connecting shaft 17. A third motor 19 is installed in the inner cavity of the mixing box 16. The output shaft of the third motor 19 is fixedly connected to the left connecting shaft 17 through a coupling. Rotating rollers 20 are installed on the outer rings of the connecting shafts 17, and the rotating rollers 20 are connected by a belt.

[0033] In the embodiment of the present utility model, when the stirring roller 15 descends to an appropriate position, the second motor 13 is started. The output shaft of the second motor 13 drives the second rotating shaft 14 to rotate through a coupling, thereby driving a plurality of stirring rollers 15 distributed in a circumferential array to rotate and stir the raw materials. During the stirring process, the first motor 4 can be started again at this time, repeating the above operation to drive the stirring roller 15 to move up and down, so as to stir the raw materials at different positions.

[0034] Please refer to Figures 1 - 5 , a vibration box 21 is installed in the inner cavity of the working box 1. A vibration plate 22 is installed in the inner cavity of the vibration box 21. Filter holes 23 are formed in the inner cavity of the vibration plate 22. The filter holes 23 are distributed in a multi-group matrix array. A limiting rod 24 is installed in the inner cavity of the vibration box 21. The vibration plate 22 is slidably sleeved on the outer ring of the limiting rod 24. A driving component is also installed at the bottom of the vibration plate 22.

[0035] The driving component includes a fourth motor 25 installed on one side of the working box 1. A fourth rotating shaft 26 is installed on one side of the output shaft of the fourth motor 25. A cam 27 is installed on the outer ring of the fourth rotating shaft 26. A groove 28 is formed at the bottom of the vibration plate 22, and the cam 27 is arranged in the inner cavity of the groove 28.

[0036] A collection box 29 is installed at the bottom of the inner cavity of the working box 1. A tempered glass 30 is installed in the inner cavity of the sealing door 3.

[0037] In the embodiment of the present utility model, the fourth motor 25 is started to drive the fourth rotating shaft 26 to rotate, thereby driving the cam 27 to rotate. The rotation of the cam 27 causes it to periodically rise and fall in the groove 28 at the bottom of the vibration plate 22, pushing the vibration plate 22 to vibrate up and down along the limiting rod 24. The vibration of the vibration plate 22 is transmitted to the raw materials on it through the filter holes 23, causing the raw materials to undergo small displacements and redistribute under the action of vibration, which helps to eliminate the accumulation of raw materials and further promotes the mixing uniformity.

[0038] During use, the raw materials enter the working box 1 through the feeding channel 2 on the left side. The sealing door 3 remains closed to ensure that the mixing process is carried out in a closed environment, preventing the escape of harmful gases or dust. The first motor 4 is started, and through the coupling, it drives the bidirectional lead screw 6 to rotate. The rotation of the bidirectional lead screw 6 causes the first moving blocks 7 on both sides to move relative to or towards each other along the external thread of its outer circle, thereby driving the lifting plate 8 to rotate with the pin shaft as the axis connection point. The rotation of the lifting plate 8 drives the second moving block 9 to slide along the chute 11 on the top plate 10, and drives the top plate 10 and the stirring assembly below it to descend or ascend, realizing the vertical position adjustment of the stirring roller 15.

[0039] When the stirring roller 15 descends to an appropriate position, the second motor 13 is started. The output shaft of the second motor 13 drives the second rotating shaft 14 to rotate through the coupling, and then drives a plurality of stirring rollers 15 distributed in a circumferential array to rotate, stirring the raw materials. During the stirring process, at this time, the first motor 4 can be started again to repeat the above operation, driving the stirring roller 15 to move up and down, so as to stir the raw materials at different positions.

[0040] The third motor 19 is started. The third motor 19 drives the left connecting shaft 17 to rotate, and drives the rotating roller 20 on the left to rotate. Through belt transmission, all the rotating rollers 20 are driven to rotate synchronously, and then drives the mixing roller 18 to rotate. The rotation of the mixing roller 18 further mixes the raw materials close to it, preventing the raw materials that have not been stirred by the stirring roller 15 from caking.

[0041] The fourth motor 25 is started, driving the fourth rotating shaft 26 to rotate, and then driving the cam 27 to rotate. The rotation of the cam 27 causes it to periodically rise and fall in the groove 28 at the bottom of the vibrating plate 22, pushing the vibrating plate 22 to vibrate up and down along the limiting rod 24. The vibration of the vibrating plate 22 is transmitted to the raw materials on it through the filtering holes 23, causing the raw materials to undergo small displacements and redistributions under the action of vibration, which helps to eliminate the accumulation of raw materials and further promote the mixing uniformity.

[0042] After a certain period of stirring and mixing, the raw materials reach a uniform mixing state and enter the inner cavity of the collection box 29. The mixed raw materials are collected through the collection box 29. The design of the tempered glass 30 facilitates observing the mixing situation of the raw materials in the working box 1 during the operation process.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits. The scope of the present invention is defined by the appended claims and their equivalents.
