Description

Technical Field

[0001] The utility model relates to the technical field of rotational viscometers, and particularly to a rotational viscometer for PEF polyester characterization. Background Technique

[0002] A rotational viscometer is used to measure the viscous resistance and dynamic viscosity of liquids, and is widely used for measuring the viscosities of various fluids such as oils, paints, plastics, foods, drugs, cosmetics, adhesives, and papermaking chemicals. It is a precision instrument for monitoring and controlling the stability of product quality in production.

[0003] The utility model patent application document with the publication number of "CN205506614U" discloses a digital rotational viscometer, which mainly consists of a digital console, a base, and a sample constant-temperature device. The technical solution fills the data output by the temperature sensor into the constant-temperature device, quickly heats to the original temperature of the sample by using a heating wire, and keeps the temperature by a heat-insulating layer, so that the test sample is greatly ensured to be at a constant temperature during the test. The connection between the heat-insulating cover and the sealing rubber ring of the constant-temperature device improves the heat preservation performance, and through the above measures, the test sample parameters are more intuitive and accurate.

[0004] The rotational viscometer disclosed in the above document has the following defects: when it is used on a relatively smooth tabletop, the base of the rotational viscometer is not provided with a structure to increase friction, which will cause the base to shift on the tabletop when vibration occurs, resulting in inaccurate detection data.

[0005] It can be seen from this that the base of the existing rotational viscometer does not have a good stabilizing component, and it is necessary to improve the existing deficiencies and provide a rotational viscometer for PEF polyester characterization. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a rotational viscometer for PEF polyester characterization to solve the problem that the base of the existing rotational viscometer does not have a good stabilizing component.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model is a rotational viscometer for PEF polyester characterization, including a base. A column and two clamping components are installed on the upper surface of the base. A cylinder is arranged between the two clamping components. A limit seat is slidably connected to the outer surface of the column. A threaded hole is opened on the outer surface of the limit seat. A first knob is installed inside the threaded hole. A motor is installed on the upper surface of the limit seat. The output end of the motor penetrates the limit seat and is equipped with a rotor. A placement groove is opened on the upper surface of the base, and a stabilizing component is arranged inside the placement groove.

[0009] Further, the clamping assembly includes a connecting plate. Connecting ear blocks are provided at both ends of the connecting plate. The connecting ear blocks are installed on the upper surface of the base by bolts. Threaded holes are formed on the outer surface of the connecting plate. A first one-way screw is installed inside the threaded holes. A clamping plate is installed at one end of the first one-way screw, and a rotating handle is installed at the other end of the first one-way screw.

[0010] Further, a sponge layer is provided on the outer surface of the clamping plate, and the sponge layer abuts against the outer surface of the cylinder body.

[0011] Further, the stabilizing assembly includes a connecting seat. The connecting seat is installed inside the placement groove. An installation hole is formed on the upper surface of the connecting seat. A second one-way screw is slidably connected inside the installation hole. A suction cup is installed on the lower surface of the second one-way screw. A second knob is provided on the upper surface of the connecting seat. A threaded hole is formed on the lower surface of the second knob, and a second one-way screw is installed inside the threaded hole.

[0012] Further, a sealing groove is formed on the lower surface of the connecting seat, and a sealing gasket is installed inside the sealing groove. The outer surface of the sealing gasket abuts against the outer surface of the suction cup.

[0013] Further, a protective shell is installed inside the placement groove. The lower surface of the protective shell abuts against the upper surface of the connecting seat, and a second knob is provided inside the protective shell.

[0014] The utility model has the following beneficial effects:

[0015] (1) By means of the stabilizing assembly provided in the utility model, the base can be adsorbed on a smooth tabletop, avoiding the base from shifting on the tabletop when vibrating, thereby causing inaccurate detection data, and achieving a good stabilizing effect.

[0016] (2) By rotating the rotating handle clockwise in the utility model, the rotating handle drives the first one-way screw to rotate, so that the first one-way screw moves axially towards one end of the cylinder body with the threaded hole formed on the outer surface of the connecting plate as the center, making the clamping plate abut against the outer wall of the cylinder body, realizing the clamping of the cylinder body. The cylinder body can be stably fixed directly below the rotor under the action of the clamping assembly, thereby avoiding the cylinder body from shaking during detection and improving the accuracy of detection data.

[0017] Of course, it is not necessary for any product implementing the utility model to simultaneously achieve all the above-mentioned advantages. Description of the Drawings

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1 - Figure 5As shown in the figure, the utility model relates to a rotational viscometer for PEF polyester characterization, which comprises a base 1. A column 2 and two clamping assemblies 3 are installed on the upper surface of the base 1. A cylinder 4 is arranged between the two clamping assemblies 3. A limit seat 5 is slidably connected to the outer surface of the column 2. A threaded hole is formed on the outer surface of the limit seat 5, and a first knob 6 is installed inside the threaded hole. A motor 7 is installed on the upper surface of the limit seat 5. The output end of the motor 7 penetrates through the limit seat 5 and is provided with a rotor 8. A placement groove 101 is formed on the upper surface of the base 1, and a stabilizing assembly 9 is arranged inside the placement groove 101;

[0028] When detecting a fluid, first place the fluid to be detected inside the cylinder 4, and then place the cylinder 4 directly below the rotor 8. By rotating the first knob 6 counterclockwise, the limit seat 5 moves downward along the axis. When the limit seat 5 moves downward, the rotor 8 will gradually penetrate into the cylinder 4. When the rotor 8 moves to a suitable position, stop rotating the first knob 6. By starting the motor 7, the output end of the motor 7 drives the rotor 8 to rotate, so that the rotor 8 detects the fluid inside the cylinder 4. When the fluid detection is completed, turn off the motor 7. By rotating the first knob 6 clockwise, the limit seat 5 moves upward along the axis. When the limit seat 5 moves upward, the rotor 8 will gradually disengage from the inside of the cylinder 4. When the rotor 8 completely disengages from the inside of the cylinder 4, stop rotating the first knob 6, and then take out the cylinder 4 to complete the fluid detection;

[0029] The clamping assembly 3 includes a connecting plate 301. Connecting ear blocks 302 are arranged at both ends of the connecting plate 301. The connecting ear blocks 302 are installed on the upper surface of the base 1 through bolts. A threaded hole is formed on the outer surface of the connecting plate 301, and a first one-way screw 303 is installed inside the threaded hole. A clamping plate 304 is installed at one end of the first one-way screw 303, and a rotating handle 305 is installed at the other end of the first one-way screw 303;

[0030] When detecting a fluid, by rotating the rotating handle 305 clockwise, the rotating handle 305 drives the first one-way screw 303 to rotate, so that the first one-way screw 303 moves axially towards one end of the cylinder 4 with the threaded hole formed on the outer surface of the connecting plate 301 as the center, making the clamping plate 304 abut against the outer wall of the cylinder 4 to clamp the cylinder 4. Rotating the rotating handle 305 in the reverse direction can cancel the clamping of the cylinder 4 by the clamping plate 304. The cylinder 4 can be stably fixed directly below the rotor 8 under the action of the clamping assembly 3, thus avoiding the shaking of the cylinder 4 during detection and improving the accuracy of the detection data;

[0031] A sponge layer is arranged on the outer surface of the clamping plate 304, and the sponge layer abuts against the outer surface of the cylinder 4;

[0032] The sponge layer provided on the outer surface of the clamping plate 304 can enhance the protection effect of the clamping plate 304 on the cylinder body 4;

[0033] The stabilizing assembly 9 includes a connecting seat 901 which is installed inside the placement groove 101. An installation hole is formed on the upper surface of the connecting seat 901. A second one-way screw rod 902 is slidably connected inside the installation hole. A suction cup 903 is installed on the lower surface of the second one-way screw rod 902. A second knob 904 is provided on the upper surface of the connecting seat 901. A threaded hole is formed on the lower surface of the second knob 904, and the second one-way screw rod 902 is installed inside the threaded hole;

[0034] A sealing groove is formed on the lower surface of the connecting seat 901, and a sealing gasket 905 is installed inside the sealing groove. The outer surface of the sealing gasket 905 abuts against the outer surface of the suction cup 903;

[0035] When the base 1 is placed on a smooth tabletop, by rotating the second knob 904, the second one-way screw rod 902 moves axially upward or downward with the threaded hole formed on the lower surface of the second knob 904 as the center. When the second one-way screw rod 902 moves upward in the installation hole, the second one-way screw rod 902 pulls the suction cup 903 upward, causing negative pressure to be generated inside the suction cup 903. As a result, the base 1 can be adsorbed on the tabletop, preventing the base 1 from shifting on the tabletop when vibrating, which may lead to inaccurate detection data, thus achieving a good stabilizing effect. When the second one-way screw rod 902 moves downward in the installation hole, the second one-way screw rod 902 pushes the suction cup 903 downward, causing the suction cup 903 to gradually squeeze the tabletop, discharging the negative pressure inside the suction cup 903, and thus canceling the adsorption effect between the suction cup 903 and the tabletop;

[0036] A protective shell 10 is installed inside the placement groove 101. The lower surface of the protective shell 10 abuts against the upper surface of the connecting seat 901. The second knob 904 is arranged inside the protective shell 10;

[0037] By providing the protective shell 10, it can provide a certain protection effect for the stabilizing assembly 9 inside the placement groove 101. At the same time, it can also prevent dust and debris from entering the inside of the placement groove 101, affecting the service life and use effect of the stabilizing assembly 9.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific embodiments described. Obviously, according to the content of this specification, many modifications and variations can be made.
