[0002] In the production and quality control of new chemical materials (such as polymer gels, epoxy resins, functional coatings, molten polymers, etc.), viscosity is a core indicator that characterizes the fluidity, processing performance and stability of materials. Its detection accuracy directly determines whether the product meets production standards and application requirements. Rotary viscometers have become the mainstream equipment for viscosity testing of new chemical materials because they can simulate the shear environment in the actual material processing process (such as the shear state during paint spraying and plastic injection molding).

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0029] Please refer to Figures 1-7The present invention provides a technical solution: a viscometer for quality testing of new chemical materials, including a base 1, an ultrasonic cleaning box 2 fixed on the base 1, a material transfer mechanism 3 for automatically loading and unloading sample cylinders 4 fixed on the base 1, a bracket 5 fixed on the rear side of the base 1, a first motor 6 fixed on the bracket 5, the output shaft of the first motor 6 is connected to a threaded rod 7 connected to the bearing on the bracket 5, and the threaded rod 7 is connected to a moving frame 8 to move the moving frame 8 in the Z-axis direction, the moving frame 8 is fixed to the main unit 9, and an adjustment mechanism 10 and a detection mechanism 11 are provided below the main unit 9;

[0030] The adjustment mechanism 10 can both adjust the position of the two detection mechanisms 11 and automatically lock the position of the two detection mechanisms 11. The adjustment mechanism 10 is fixed below the main unit 9.

[0031] The detection mechanism 11 can both detect the viscosity of the sample inside the sample cylinder 4 and perform negative pressure exhaust of the sample to avoid air bubbles affecting the accuracy of the detection. The detection mechanism 11 is connected to the adjustment mechanism 10.

[0032] The material transfer mechanism 3 includes a limiting frame 301 that is fixed to the base 1, and a feeding conveyor 302 is fixed to the right side of the limiting frame 301, and a discharging conveyor 303 is fixed to the left side of the limiting frame 301.

[0033] When using a viscometer for quality testing of new chemical materials, such as Figures 1-7 As shown, by placing the sample cylinder 4 containing the sample on the feeding conveyor 302, the feeding conveyor 302 transports the sample cylinder 4 from right to left, thereby enabling the leftmost sample cylinder 4 to cooperate with the right positioning groove 310 on the turntable 309, thus achieving the positioning of the sample cylinder 4.

[0034] The material moving mechanism 3 further comprises a rotating shaft 304 connected to the base 1 through a bearing, and a first gear 305 is fixed on the rotating shaft 304, and the first gear 305 is connected to a second gear 306 through a toothed belt, while the second gear 306 is fixed to a vertical rod 307 connected to the base 1 through a bearing, and the vertical rod 307 is connected to the slide rod 308 in a sliding manner, and the number of teeth of the second gear 306 is half of that of the first gear 305; the adjusting mechanism 10 comprises a fixed frame 1001 fixed to the lower end surface of the main machine 9, and a second motor 1002 is fixed on the fixed frame 1001, and an installation plate 1003 is fixed on the output shaft of the second motor 1002, while the installation plate 1003 is fixedly connected to the slide rod 308, and the installation plate 1003 rotates 180° each time, and a fixed rod 1004 is further fixed on the output shaft of the second motor 1002, and a positioning sleeve 1005 is fixed to the end of the rotating disc 309, and a horn hole is formed in the positioning sleeve 1005, and the second motor 1002 is electrically connected to the first controller 801; a guide rod 1006 is slidably connected to the fixed frame 1001, and a positioning shaft 1007 is fixed on the guide rod 1006, and the positioning shaft 1007 is nested in the horn hole of the positioning sleeve 1005 to realize positioning, and a second spring 1008 is fixed between the guide rod 1006 and the fixed frame 1001, and the guide rod 1006 is located directly below a positioning plate 1009, and the positioning plate 1009 is symmetrically fixed to the support 5;

[0035] At this time, the positioning plate 1009 is in contact with the guide rod 1006, so that the positioning shaft 1007 and the horn hole of the positioning sleeve 1005 are in a separated state, and the second spring 1008 is in a contracted state, and then the second motor 1002 is controlled to drive the installation plate 1003 to rotate counterclockwise by 180°, and when the installation plate 1003 rotates, the slide rod 308, the vertical rod 307 and the second gear 306 are simultaneously driven to rotate counterclockwise by 180°, and when the second gear 306 rotates, the first gear 305, the rotating shaft 304 and the rotating disc 309 can be simultaneously driven to rotate counterclockwise by the transmission action of the toothed belt, and since the number of teeth of the second gear 306 is half of that of the first gear 305, when the second gear 306 rotates by 180°, the first gear 305, the rotating shaft 304 and the rotating disc 309 rotate counterclockwise by 90°, thereby driving the sample cylinder 4 in the positioning groove 310 to rotate by 90°, realizing automatic feeding of the sample cylinder 4, and when the sample cylinder 4 rotates, the limiting action of the limiting frame 301 can ensure the stability of the rotation of the sample cylinder 4, and at this time the sample cylinder 4 is located directly below the front detection mechanism 11 for detection, and according to the above principle, continuous feeding of the sample cylinder 4 can be realized;

[0036] The moving frame 8 is slidably connected to the support 5, and a first controller 801 is fixed to the support 5 above the moving frame 8;

[0037] When the sample cylinder 4 moves to the front of the detection mechanism 11, the threaded rod 7 is rotated by the first motor 6, so that the moving frame 8 is forced to move downward, thereby driving the main machine 9, the adjusting mechanism 10 and the detection mechanism 11 to move downward. During the downward movement of the adjusting mechanism 10, when the positioning plate 1009 is separated from the upper end of the guide rod 1006, the guide rod 1006 and the positioning shaft 1007 move upward relative to the fixed frame 1001 under the elastic action of the second spring 1008, so that the positioning shaft 1007 is nested with the upper horn hole of the positioning sleeve 1005 to realize positioning, thereby realizing the position locking of the mounting plate 1003, the detection mechanism 11 and the rotating disc 309, ensuring the normal operation of subsequent detection. When the front detection mechanism 11 moves downward to cooperate with the sample cylinder 4, the viscosity of the sample in the sample cylinder 4 can be detected by the detection mechanism 11. At this time, the rear detection mechanism 11 enters the ultrasonic cleaning tank 2 for cleaning, providing a basis for subsequent continuous detection. After detection, the threaded rod 7 is reversely rotated by the first motor 6, so that the main machine 9, the adjusting mechanism 10 and the detection mechanism 11 move upward to reset. When the guide rod 1006 is in contact with the positioning plate 1009, the positioning shaft 1007 is separated from the upper horn hole of the positioning sleeve 1005 to unlock. After unlocking, when the moving frame 8 moves upward to contact the first controller 801, the second motor 1002 drives the mounting plate 1003 to rotate counterclockwise by 180°, so as to realize the position exchange of the front and rear detection mechanisms 11, and to facilitate the subsequent cleaning of the detection mechanism 11.

[0038] The rotating shaft 304 is fixed with the rotating disc 309, and the rotating disc 309 is provided with four positioning grooves 310 at equal angles. The pushing plate 311 is slidably connected to the rotating disc 309, and the pushing plate 311 and the positioning grooves 310 are one-to-one corresponding. The horizontal rod 312 is fixed to the pushing plate 311 and slidably connected to the rotating disc 309. The first spring 313 is fixed between the pushing plate 311 and the rotating disc 309. The round rod 314 is slidably connected between the pushing plate 311 and the rotating disc 309. The permanent magnet 315 is fixed to the round rod 314. The permanent magnet 315 and the permanent magnet plate 316 fixed to the base 1 form a magnetic attraction structure. The rotating disc 309 rotates 90° each time.

[0039] When the second motor 1002 drives the mounting plate 1003 to rotate counterclockwise by 180° after the detection of one sample cylinder 4 is completed, the rotating disc 309 can be synchronously rotated counterclockwise by 90°, so as to realize the feeding of the next sample cylinder 4. At this time, the first detected sample cylinder 4 is rotated to the rightmost side, and the permanent magnet 315 at the corresponding position of the first detected sample cylinder 4 is just rotated to cooperate with the permanent magnet plate 316. Through the magnetic attraction between the permanent magnet plate 316 and the permanent magnet 315, the pushing plate 311 is forced to move leftward. In cooperation with the sliding action between the circular rod 314 and the rotating disc 309, the stability of the movement of the pushing plate 311 can be ensured. Through the action of the pushing plate 311, the first detected sample cylinder 4 can be pushed to contact with the unloading conveyor 303. Through the unloading conveyor 303, the detected sample cylinder 4 can be automatically unloaded, so as to provide basic guarantee for the continuous detection of multiple sample cylinders 4.

[0040] The detection mechanism 11 comprises a pressing plate 1101 arranged below the mounting plate 1003, and a sealing gasket 1102 is fixed to the lower end surface of the pressing plate 1101. The sealing gasket 1102 cooperates with the sample cylinder 4 to realize sealing. A third motor 1103 is further fixed to the pressing plate 1101, and a detection head 1104 is fixed to the output end of the third motor 1103. The detection head 1104 and the pressing plate 1101 are connected by bearings. A third spring 1105 is fixed between the pressing plate 1101 and the mounting plate 1003, and the pressing plate 1101 is symmetrically distributed about the center line of the mounting plate 1003. A piston 1106 is fixed to the pressing plate 1101, and the piston 1106 and a cylinder 1107 are connected by sliding. A plurality of air holes 1108 are equally arranged on the cylinder 1107, and a gas guide pipe penetrating through the pressing plate 1101 and the sealing gasket 1102 is further connected to the cylinder 1107. A second sensor 1109 is fixed to the cylinder 1107, and the second sensor 1109 and the third motor 1103 are electrically connected.

[0041] When the moving frame 8 moves downward to drive the detection mechanism 11 to move downward and cooperate with the sample cylinder 4 to detect, as shown in FIG. 8, the pressing plate 1101 is driven by the third motor 1103 to move downward to the position of the sample cylinder 4, and the sealing gasket 1102 is in contact with the sample cylinder 4 to realize sealing. Figures 1-7As shown, during the moving down of the detection mechanism 11, when the sealing gasket 1102 contacts the upper end opening of the sample cylinder 4, the sealing of the upper end opening of the sample cylinder 4 can be realized, and at this time, the detection head 1104 contacts the sample in the sample cylinder 4, and the moving frame 8 continues to move down, so that the pressing plate 1101 moves relative to the mounting plate 1003, at this time, the piston 1106 slides upward in the cylinder 1107, so that the negative pressure is formed in the cylinder 1107, and in cooperation with the action of the air guide pipe, the negative pressure can be formed in the sample cylinder 4, and through the action of the negative pressure, the bubbles in the sample in the sample cylinder 4 can be discharged, so that the influence of the existence of the bubbles in the sample in the sample cylinder 4 on the accuracy of the detection data can be effectively reduced, until the pressing plate 1101 moves to contact the second sensor 1109, at this time, the second sensor 1109 controls the third motor 1103 to start driving the detection head 1104 to rotate, so that the detection of the viscosity of the sample in the sample cylinder 4 is realized;

[0042] In summary, through the adjusting mechanism 10, the position adjustment of the two detection mechanisms 11 can be realized, so as to realize the cleaning of the detection mechanism 11, and provide basic guarantee for the continuous detection of the sample, and the adjusting and controlling of the rotating disc 309 can be realized at the same time, so that the automatic feeding and discharging of the sample cylinder 4 is realized, and the normal operation of the device is ensured, and in cooperation with the negative pressure exhaust action in the detection mechanism 11, the bubbles in the sample can be removed before the sample is detected, so as to avoid the influence of the existence of the bubbles on the accuracy of the detection data.
