A cleaning box 14 is fixedly connected to the top of the sliding plate 11, and a feeding pipe 15 is fixedly sleeved on the front of the cleaning box 14. A No. 2 motor 16 is fixedly installed on the top of the sliding plate 11, and a No. 2 blade 17 is fixedly sleeved on the output shaft of the No. 2 motor 16. A clamping mechanism 18 is arranged on the side of the positioning frame 12, a sliding mechanism 19 is arranged on the top of the support plate 1, and a moving mechanism 20 is arranged on the bottom of the support plate 1, and a sliding ball 21 is movably sleeved on the top of the lifting plate 3.

[0025] The No. 2 blade 17 is movably sleeved inside the cleaning box 14, and the No. 2 blade 17 is made of stainless steel. By setting the No. 2 blade 17, when the rotating sleeve 4 finishes working, the rotating sleeve 4 is sleeved inside the cleaning box 14. At this time, the cleaning liquid is injected into the cleaning box 14 through the feeding pipe 15 and the No. 2 motor 16 is started, so that the No. 2 motor 16 can drive the cleaning liquid inside the rotating sleeve 4 to roll violently through the No. 2 blade 17, so that the rolling cleaning liquid can flush the rotating sleeve 4, thereby achieving the cleaning effect inside the rotating sleeve 4, so that the measuring material adhered to the inner wall of the rotating sleeve 4 can fall off to the inside of the cleaning box 14, thereby avoiding the problem that the measuring meter cannot be used multiple times when the measuring material adheres to the inside of the measuring meter, thereby improving the use efficiency of the measuring meter.

[0026] The rotating sleeve 4 is located directly above the containing tank 13, and the rotating sleeve 4 and the lifting plate 3 are perpendicular to each other; by setting the rotating sleeve 4, when it is necessary to measure the viscosity of the material, the rotating sleeve 4 is sleeved inside the containing tank 13, and then the No. 1 motor 6 and the torque tester 5 are started, so that the No. 1 motor 6 can drive the viscous material to rotate through the No. 1 blade 7, and then drive the rotating sleeve 4 to rotate. At this time, the torque tester 5 can measure the torque of the rotating rotating sleeve 4, thereby achieving the viscosity measurement effect of the viscous material.

[0027] The cylinder 2 and the support plate 1 are perpendicular to each other, and there are four cylinders 2. By setting up the cylinder 2, when the viscosity of the viscous material needs to be measured, the material is injected into the interior of the containing tank 13. At this time, the cylinder 2 is started, so that the cylinder 2 can drive the rotating sleeve 4 to be sleeved on the interior of the containing tank 13 through the lifting plate 3, thereby facilitating the measurement of the viscous material.

[0028] The clamping mechanism 18 includes a stretching rod 181, which is movably sleeved inside the positioning frame 12, and a spring 182 is movably sleeved outside the stretching rod 181, and one end of the stretching rod 181 is fixedly connected to an extrusion sleeve 183; by setting the clamping mechanism 18, when it is necessary to measure the viscous material, the stretching rod 181 is pulled so that the stretching rod 181 can drive the extrusion sleeve 183 to move, and at this time, the containing tank 13 is sleeved inside the positioning frame 12 and the stretching rod 181 is released, so that the spring 182 can drive the extrusion sleeve 183 to be squeezed on the side of the containing tank 13 through the stretching rod 181, thereby achieving the fixing effect of the containing tank 13.

[0029] The sliding mechanism 19 includes a No. 3 motor 191, which is fixedly installed on one side of the top of the support plate 1, and a threaded rod 192 is fixedly connected to the output shaft of the No. 3 motor 191, and the threaded rod 192 is threadedly sleeved inside the sliding block 10; by setting the sliding mechanism 19, when it is necessary to adjust the position of the cleaning box 14, start the No. 3 motor 191, so that the No. 3 motor 191 can drive the sliding block 10 to move horizontally through the threaded rod 192, that is, drive the cleaning box 14 to move directly below the rotating sleeve 4, so that the rotating sleeve 4 can move to the inside of the cleaning box 14, thereby facilitating the movement of the cleaning box 14.

[0030] The moving mechanism 20 includes a support column 201, which is fixedly connected to the bottom of the support plate 1, and a sliding wheel 202 is installed at the bottom of the support column 201; by setting the moving mechanism 20, when the working position of the viscometer needs to be adjusted, the support plate 1 is pushed, so that the sliding wheel 202 can drive the support plate 1 to move horizontally through the support column 201, that is, drive the torque tester 5 to move horizontally, thereby facilitating the adjustment of the working position of the viscometer.

[0031] The outside of the sliding ball 21 is in close contact with the top of the rotating sleeve 4, and the number of the sliding balls 21 is several; by setting the sliding balls 21, when the rotating sleeve 4 rotates to measure the viscosity of the material, the sliding balls 21 can support the rotating sleeve 4 in rotation, so as to avoid the friction between the rotating sleeve 4 and the top of the lifting plate 3 when rotating, resulting in a large error in the torsional force measurement of the rotating sleeve 4, and then causing a large error in the viscosity measurement, thereby improving the accuracy of the viscosity measurement of the viscous material.

[0032] The working principle of a rotational viscometer provided by the utility model is as follows:

[0033] Step 1: When the rotating sleeve 4 finishes working, the rotating sleeve 4 is sleeved inside the cleaning box 14. At this time, the cleaning liquid is injected into the cleaning box 14 through the feeding pipe 15 and the No. 2 motor 16 is started, so that the No. 2 motor 16 can drive the cleaning liquid inside the rotating sleeve 4 to roll violently through the No. 2 blade 17, so that the rolling cleaning liquid can flush the rotating sleeve 4, thereby achieving the cleaning effect inside the rotating sleeve 4, so that the measuring material adhered to the inner wall of the rotating sleeve 4 can fall off to the inside of the cleaning box 14, thereby avoiding the problem that the measuring meter cannot be used multiple times when the measuring material adheres to the inside of the measuring meter, thereby improving the use efficiency of the measuring meter. When the viscosity of the material needs to be measured, the rotating sleeve 4 is sleeved inside the holding tank 13. At this time, the No. 1 motor 6 and the torque tester 5 are started, so that the No. 1 motor 6 can drive the viscous material to rotate through the No. 1 blade 7, and then drive the rotating sleeve 4 to rotate. At this time, the torque tester 5 can measure the torque of the rotating rotating sleeve 4, thereby achieving the viscosity measurement effect of the viscous material. When the viscosity of the viscous material needs to be measured, the material is injected into the holding tank 13. At this time, the cylinder 2 is started, so that the cylinder 2 can drive the rotating sleeve 4 to be sleeved inside the holding tank 13 through the lifting plate 3, thereby bringing convenience to the measurement of the viscous material;

[0034] Step 2: When it is necessary to measure the viscous material, the stretching rod 181 is pulled so that the stretching rod 181 can drive the extrusion sleeve 183 to move. At this time, the receiving tank 13 is sleeved inside the positioning frame 12 and the stretching rod 181 is loosened, so that the spring 182 can drive the extrusion sleeve 183 to be squeezed on the side of the receiving tank 13 through the stretching rod 181, thereby achieving the fixing effect of the receiving tank 13. When it is necessary to adjust the position of the cleaning box 14, the No. 3 motor 191 is started so that the No. 3 motor 191 can drive the sliding block 10 to move horizontally through the threaded rod 192, that is, drive the cleaning box 14 to move to the bottom of the rotating sleeve 4, so that the rotating sleeve 4 can move To the inside of the cleaning box 14, thereby facilitating the movement of the cleaning box 14. When the working position of the viscometer needs to be adjusted, the support plate 1 is pushed, so that the sliding wheel 202 can drive the support plate 1 to move horizontally through the support column 201, that is, drive the torque tester 5 to move horizontally, thereby facilitating the adjustment of the working position of the viscometer. When the rotating sleeve 4 rotates to measure the viscosity of the material, the sliding ball 21 can support the rotating sleeve 4 in rotation, so as to avoid the friction between the rotating sleeve 4 and the top of the lifting plate 3 when rotating, resulting in a large error in the torsional force measurement of the rotating sleeve 4, and then leading to the problem of large viscosity measurement error, thereby improving the accuracy of the viscosity measurement of the viscous material.

[0035] Compared with the related art, the rotary viscometer provided by the utility model has the following beneficial effects:

[0036] By setting the No. 2 blade 17, when the rotating sleeve 4 finishes working, the rotating sleeve 4 is sleeved inside the cleaning box 14. At this time, the cleaning liquid is injected into the cleaning box 14 through the feeding pipe 15 and the No. 2 motor 16 is started, so that the No. 2 motor 16 can drive the cleaning liquid inside the rotating sleeve 4 to roll violently through the No. 2 blade 17, so that the rolling cleaning liquid can flush the rotating sleeve 4, thereby achieving the cleaning effect of the inside of the rotating sleeve 4, so that the measuring material adhered to the inner wall of the rotating sleeve 4 can fall off to the inside of the cleaning box 14, thereby avoiding the problem that the measuring meter cannot be used multiple times when the measuring material adheres to the inside of the measuring meter, thereby improving the use efficiency of the measuring meter.
