DETAILED DESCRIPTION

[0021] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods.

[0022] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0023] See also Figure 1-Figure 4In one embodiment, a performance testing device for polyanionic cellulose includes a viscosity detector 3, a rotor 6, a telescopic member 2, an L-shaped plate 1, a connector 9, a standard block 4, a rotating rod 10, and a first spring 11. The vertical end of the L-shaped plate 1 is equipped with a telescopic member 2, and the output end of the telescopic member 2 is fixedly connected to the viscosity detector 3. A connector 9 is installed at one end of the viscosity detector 3, and the connector 9 is detachably connected to the rotor 6. A standard block 4 is installed on the outside of the connector 9, and the standard block 4 is detachably connected to the connector 9. A humidity sensor is installed on the lower surface of the standard block 4.

One end of the first spring 11 is fixedly connected to one side of the rotating rod 10, and the other end of the first spring 11 is fixedly connected to the rotor 6. A card block 13 is installed at the end of the rotating rod 10 away from the rotor 6, and a card slot 15 is opened on the inner side of the standard block 4.

[0024] In this embodiment, the connection between the connector 9 and the rotor 6 can be achieved by snap-fitting, that is, a plurality of movable blocks are provided on the circumferential surface of the rotor 6, a spring is installed at one end of the movable block, and a corresponding notch is provided on the inner side of the connector 9. The connector 9 and the rotor 6 are installed in a pushing manner. When the movable block is pushed into the notch, the snap-fitting is completed. The connection structure between the standard block 4 and the connector 9 can also adopt the above-mentioned form, and the specific detachable structure is not limited to the above-mentioned structure.

[0025] When testing the viscosity of polyanionic cellulose, the rotor 6 is first connected to the connector 9. After the connection is completed, the connection between the connector 9 and the standard block 4 is released. At this time, the standard block 4 falls along the rotor 6 until the standard block 4 reaches the position of the rotating rod 10. Under the action of gravity, the standard block 4 squeezes the first spring 11 while falling, that is, the rotating rod 10 rotates. When the standard block 4 falls to the lowest end of the rotating rod 10, the block 13 on the rotating rod 10 just enters the position of the slot 15, thereby completing the clamping, that is, the position of the standard block 4 is limited. At this time, the lower surface of the standard block 4 is just located on the liquid level scale line of the rotor 6, and the telescopic movement is started.

When the upper liquid surface of the object to be tested is in contact with the lower surface of the standard block 4, that is, the rotor 6 just reaches the test position, the humidity sensor obtains corresponding data, that is, the change in humidity is large. At this time, the telescopic part 2 stops extending and retracting. The humidity sensor and the telescopic part 2 are connected to the controller, and the controller controls the telescopic part 2 to be shut down when the change in the humidity sensor is large. At this time, the viscosity tester 3 is started, and the data is obtained by driving the rotor 6 to rotate. In this embodiment, while the liquid level scale line is positioned by the standard block 4, the standard block 4 covers the upper liquid surface, which can avoid splashing of the object to be tested when the rotor 6 is rotated for detection. After the detection is completed, the telescopic part 2 is driven in reverse to return to the initial position.

After the connection between the rotor 6 and the connector 9 is completed, the standard block 4 is loosened so that the standard block 4 is separated from the connector 9, thereby causing the standard block 4 to fall to achieve the positioning of the liquid level scale line.

A plurality of clamping blocks 5 are installed on the horizontal section of the L-shaped plate 1. The plurality of clamping blocks 5 are radially distributed.

[0032] In this embodiment, by installing a plurality of radially distributed clamping blocks 5, the container can be circumferentially clamped and fixed, and the clamping effect is better. When the viscosity of the object to be tested is high and the rotational resistance is large, it can avoid the rotor 6 rotating while driving the container to move, thereby ensuring the accuracy of the viscosity test data.

[0034] In this embodiment, the rotating ring 76 is driven to rotate by the driving member 77. The rotating ring 76 drives the first driven gears 73 to rotate while rotating, that is, drives the threaded sleeve 75 to rotate. The threaded sleeve 75 drives the screw rod 71 to move linearly while rotating, thereby driving the clamping block 5 at one end of the threaded sleeve 75 to move linearly, thereby realizing radial movement and clamping of the clamping blocks 5.

[0035] The moving assembly 7 can also be implemented by using multiple sets of bidirectional screws, and the two clamping blocks 5 are threadedly connected to a set of bidirectional screws to achieve opposite movement of the opposing clamping blocks 5, thereby achieving radial clamping.

[0037] In this embodiment, a knob 772 is also installed on the driving gear 771. By turning the knob 772, the driving gear 771 is driven to rotate, thereby driving the second fixed tooth 773 to rotate, that is, driving the rotating ring 76 to rotate. Through the setting of the knob 772, manual adjustment can be achieved, so that it can be more suitable for various types of containers, avoiding excessive clamping force and causing damage to the container.

[0039] In this embodiment, bubbles are often present when the viscometer rotor 6 penetrates deeply into the object to be tested. The presence of bubbles will cause a large deviation in the test data. A container is placed on the supporting plate 14 and the container is vibrated by the vibration assembly 8, thereby shaking out the bubbles generated when the rotor 6 penetrates deeply into the object to be tested, thereby preventing the presence of bubbles from affecting the test results, thereby making the test results more accurate.

[0040] See also Figure 1 , Figure 5 , Figure 6In one embodiment, the vibration assembly 8 includes a second driven gear 81, a rotating shaft 82, a second support frame 83, and a cam 84.

At the same time, under the action of the second spring 85, the supporting plate 14 vibrates up and down, thereby shaking out the bubbles inside the container.

[0042] Working process of the present invention:

[0043] When testing the viscosity of polyanionic cellulose, the rotor 6 is first connected to the connector 9. After the connection is completed, the connection between the connector 9 and the standard block 4 is released. At this time, the standard block 4 falls along the rotor 6 until the standard block 4 reaches the position of the rotating rod 10. Under the action of gravity, the standard block 4 squeezes the first spring 11 while falling, that is, the rotating rod 10 rotates. When the standard block 4 falls to the lowest end of the rotating rod 10, the block 13 on the rotating rod 10 just enters the position of the slot 15, thereby completing the clamping, that is, the position of the standard block 4 is limited. At this time, the lower surface of the standard block 4 is just located at When the liquid level scale line of the rotor 6 is reached, the telescopic member 2 is started, thereby driving the viscosity tester 3 to approach the object to be tested in the beaker. When the upper liquid surface of the object to be tested fits the lower surface of the standard block 4, that is, the rotor 6 just reaches the test position, the humidity sensor obtains corresponding data, that is, the humidity change is large. At this time, the telescopic member 2 stops telescoping, and then the rotating ring 76 is driven to rotate by rotating the knob 772, thereby driving a number of clamping blocks 5 to move linearly for clamping and driving the cam 84 to rotate and cooperate with the second spring 85 to achieve vibration. When the clamping and vibration operations are completed, the viscosity tester 3 is started at this time to perform viscosity detection. After the detection is completed, the telescopic member 2 is driven in reverse to return to the initial position.
