Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to a thickness automatic control device. Background Art

[0002] With the rapid economic development in recent years, mixing equipment is widely used in industrial production such as chemical industry, construction, food, and environmental protection. From the perspective of its operation, mixing can promote the mutual dispersion of two or more materials, make them fully contact, and then achieve a uniform slurry in terms of density field, concentration field, and temperature field. At present, the slurry discharging structure of the mixing equipment on the market directly discharges the slurry after mixing, and can only output a slurry with one thickness, which cannot meet the multiple needs of users. Moreover, such equipment uses a strip-shaped feeding box for feeding slurry, with a small feeding area, and problems such as material accumulation are likely to occur, affecting the processing progress. Therefore, a thickness automatic control device is needed to improve the above problems. Summary of the Utility Model

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0030] As Figure 1 and Figure 2 shown, a thickness automatic control device includes a support frame base 1, a stirring assembly 2, a slurry feeding structure 3 and a driving mechanism 4. The stirring assembly 2 and the slurry feeding structure 3 are both installed on the support frame base 1. The driving mechanism 4 is symmetrically arranged on the support frame base 1, and the output end of the driving mechanism 4 is connected to the stirring assembly 2.

[0031] The stirring assembly 2 includes a slurry discharging guide roller 20, a slurry discharging driving member 21 for driving the slurry discharging guide roller 20 to operate, a plurality of stirring guide rollers 22, a stirring driving member 23 for driving the stirring guide rollers 22 to operate, a slurry feeding guide roller 24 and a slurry feeding driving member 25 for driving the slurry feeding guide roller 24 to operate. The stirring guide rollers 22 are located between the slurry discharging guide roller 20 and the slurry feeding guide roller 24. The slurry feeding structure 3 is located on one side of the slurry feeding guide roller 24 along the Y-axis direction. The output end of the driving mechanism 4 is connected to the slurry discharging guide roller 20. The driving mechanism 4 can drive the slurry discharging guide roller 20 to move up and down along the Z-axis direction to adjust the amount of discharged slurry. The horizontal position of the slurry discharging guide roller 20 is higher than that of the stirring guide rollers 22 and the slurry feeding guide roller 24. A plurality of stirring blades are provided on both the stirring guide rollers 22 and the slurry feeding guide roller 24 to effectively stir the slurry.

[0032] It should be noted that when the slurry discharging guide roller 20, the stirring guide rollers 22 and the slurry feeding guide roller 24 rotate, the stirring blades push the surrounding slurry to form a vortex. The formation and rotation of the vortex will generate centrifugal force and shear force, thereby mixing various components inside the slurry evenly.

[0033] AsFigure 1 and Figure 2 As shown in Figure 2 , the stirring assembly 2 further includes a slurry discharging driving housing 26, a stirring driving housing 27 and a slurry feeding driving housing 28. Two clamping holes 29 are formed in each of the slurry discharging driving housing 26, the stirring driving housing 27 and the slurry feeding driving housing 28. The two clamping holes 29 are symmetrically arranged up and down and communicated. The output end of the slurry discharging driving member 21 passes through the slurry discharging driving housing 26 and is connected to the slurry discharging guide roller 20. The output end of the stirring driving member 23 passes through the stirring driving housing 27 and is connected to the stirring guide roller 22. The output end of the slurry feeding driving member 25 passes through the slurry feeding driving housing 28 and is connected to the slurry feeding guide roller 24. In this embodiment, the slurry discharging driving member 21, the stirring driving member 23 and the slurry feeding driving member 25 are all driving motors.

[0034] It should be noted that the settings of the support frame base 1, the slurry discharging driving housing 26, the stirring driving housing 27 and the slurry feeding driving housing 28 improve the overall stability of the present utility model and the working process is stable.

[0035] As Figure 3 shown, the driving mechanism 4 includes a servo motor 40, a motor housing 41, a speed reducer 42 and a motor base 43.

The output end of the servo motor 40 is connected to the speed reducer 42. The output end of the speed reducer 42 passes through the motor base 43 and is connected to the slurry discharging guide roller 20. The servo motor 40 can drive the slurry discharging guide roller 20 to move up and down along the Z-axis direction, so that the output end of the slurry discharging driving member 21 is movably clamped in the clamping hole 29. A connecting seat is sleeved on the slurry discharging guide roller 20, and the connecting seat is connected to the output end of the speed reducer 42.

[0036] It should be noted that when the servo motor 40 is started, electrical energy is converted into mechanical energy and transmitted to the speed reducer 42. The speed reducer 42 adjusts the transmission ratio to achieve a suitable rotation speed, drives the slurry discharging guide roller 20 to move up and down along the Z-axis direction, thereby realizing the change of the bottom gap of the slurry discharging guide roller and the adjustment of the slurry discharging amount, and further realizing the adjustment of the product thickness change.

The lower end of the slurry feeding box 31 is connected to the slurry feeding sector box 32 in a communicating manner. The lower end of the slurry feeding sector box 32 is connected to the slurry feeding pipe assembly 33 in a communicating manner.

[0038] It should be noted that by setting the slurry inlet box 31 and the slurry inlet sector box 32, the height of the slurry inlet channel is increased as a whole to ensure that there is no slurry overflow.

[0039] As Figure 1 , Figure 2 and Figure 4 shown, a flushing port 34 is provided at the upper end of the slurry inlet box 31, and a slurry inlet 35 is provided on one side of the slurry inlet box 31. The slurry inlet 35 is communicated with the through port of the side plate 30.

[0040] It should be noted that the present utility model adopts a design with a single slurry inlet. When the slurry is transported from the slurry inlet pipe assembly 33 to the slurry inlet box 31 and the slurry inlet sector box 32, it flows into the slurry inlet opening through the through port of the side plate 30 and then flows into the support frame base 1 for stirring.

[0041] As Figure 3 shown, a clamping block 10 and a plurality of receiving plates 11 are further provided on the support frame base 1, and the plurality of receiving plates 11 are arranged at intervals.

[0042] As Figure 3 shown, it further includes a slurry retaining plate 5. The slurry retaining plate 5 is detachably installed on the support frame base 1 and is located between the slurry inlet guide roller 24 and the side plate 30. An inclined portion 50 and a slurry inlet opening 51 are provided at the lower end of the slurry retaining plate 5. The slurry inlet openings 51 are symmetrically arranged on both sides of the inclined portion 50 along the X-axis direction. A plurality of through holes 52 are provided on the inclined portion 50. Clamping portions 53 are provided at both ends of the slurry retaining plate 5 along the X-axis direction. The clamping portions 53 are in the shape of a "7", and the clamping portions 53 are detachably connected to the clamping block 10.

[0043] It should be noted that the slurry retaining plate 5 is installed on the clamping block 10 in the support frame base 1 by a clamping method. There is no need to fix it with screws. It can be directly lifted, which is convenient to operate. It can also well control the slurry inlet volume, improve work efficiency and ensure work stability.

The shutdown slurry discharge port 6 is provided at the bottom of the support frame base 1, and the slurry outlet 7 is provided on one side of the support frame base 1.
