Description

Technical Field

[0001] The invention belongs to the field of resin viscosity testing, in particular to an unsaturated polyester resin viscosity testing device and a testing method. Background Art

[0002] Resins can be divided into natural resins and synthetic resins. Natural resins refer to amorphous organic substances obtained from secretions of animals and plants in nature, while synthetic resins refer to resin products produced by chemical synthesis of simple organic substances. Resins have a wide range of application scenarios, such as coatings and paints, the production of artworks and crafts, adhesives and bonding agents, etc.

[0003] Resin viscosity testing is an important method for evaluating resin fluidity and processing performance. By understanding the fluidity of a substance at different temperatures, the characteristics of the product can be accurately controlled to ensure that it performs optimally in a specific application.

[0004] Traditional viscosity testing devices generally control a rotor through a drive to rotate the rotor in the test liquid. After measuring the approximate viscosity, the rotor needs to be replaced according to the viscosity and a second measurement is performed in order to measure a more accurate value. However, in this process, the rotor on the drive needs to be manually replaced. During the replacement process, the test liquid and the container containing the liquid need to be removed first, and the container needs to be returned to its original position after the replacement is completed. The entire operation process is relatively complicated. At the same time, due to the detection of liquids such as resins that change their viscosity according to changes in temperature, it is necessary to maintain a constant temperature during the detection process. Since the container is transferred, it is necessary to set up a heating element to heat the container and maintain the temperature of the liquid inside the container, which leads to an increase in the number of devices required, and there are certain safety hazards in the transfer of containers at high temperatures.

[0005] To this end, the present invention provides a device and method for testing the viscosity of an unsaturated polyester resin. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is as follows: the unsaturated polyester resin viscosity testing device described in the present invention comprises a control box, the front end of the control box is set in a concave shape, a plurality of detection rotors are arranged at the concave part of the front end of the control box, the appearance and mass of the plurality of detection rotors are different, and the plurality of detection rotors are arranged linearly and equidistantly, a detection tank is arranged at the front end of the control box, the top of the detection tank is set in an open shape, and an electric heating tray for driving the detection tank to move is arranged at the bottom of the detection tank, a servo motor for controlling the rotation of the detection rotor is arranged inside the control box, and a speed measurement module for monitoring the speed of the detection rotor is arranged inside the control box;

[0008] Preferably, the resin to be tested is placed in the test tank through the setting of a control box and an electric heating tray. The electric heating tray has a built-in heating wire, which can evenly heat the test tank from the bottom to keep the resin inside the test tank at a constant temperature. The electric heating tray can move horizontally and up and down to move the test tank to the bottom of the test rotor in the middle, and then rise to allow the test rotor to be inserted into the resin in the test tank. The test rotor in the middle is controlled to rotate by a servo motor. The viscosity of the resin will bring resistance to the rotation of the test rotor, resulting in the rotation speed of the test rotor being affected under the same power consumption of the servo motor. The speed of the test rotor is monitored in real time by a speed measurement module, and then by comparing the normal speed of the test rotor without the influence of the resin, the viscosity value of the resin can be calculated. The number of test rotors can be five, and the volume and surface area of ​​the five test rotors increase from one end to the other. The larger the surface area, the higher the rotation speed. The detection rotor is increasingly affected by viscosity. It is used to detect resin solutions at different viscosities. First, the resin solution is detected with the detection rotor in the middle position. When the viscosity is detected for the first time, the position of the detection tank can be adjusted according to the viscosity value. The electric heating tray will transfer the detection tank to the bottom of another detection rotor for secondary detection. The purpose is to measure the viscosity of the resin more accurately. Since the viscosity of the resin changes with temperature, in order to detect the viscosity value of the resin at different temperatures, the resin temperature is changed by the electric heating tray, and then the position of the detection tank is changed by the electric heating tray. Through this setting, the test process is effectively simplified, and there is no need to frequently replace the detection rotor. The viscosity of the resin in different states can also be detected. There is no need to manually touch the detection tank during the entire process. The detection tank is always on the electric heating tray to ensure the constant temperature of the internal resin, thereby ensuring the accuracy of the test data.

[0009] Preferably, a transmission shaft is fixedly connected to the top of the detection rotor, a restraining sleeve fixedly connected to the regulating box is sleeved on the outer side of the transmission shaft, a driven gear is fixedly connected to the top of the transmission shaft, a driving gear is arranged inside the regulating box, the servo motor is fixedly connected to the output end of the driving gear, the bottom detection end of the speed measurement module is connected to the middle part of the top surface of the driving gear, a lead screw nut mechanism 1 and two electric telescopic rods 2 for driving the servo motor to move are arranged on the inner side of the regulating box, the positions of multiple detection rotors are limited by the restraining sleeve, and when a certain detection rotor needs to rotate, the lead screw nut mechanism 1 will first drive the entire servo motor The driving gear is translated until the driving gear and the corresponding driven gear are aligned, and then the electric telescopic rod 2 controls the driving gear to approach the driven gear and make them mesh with each other, and then the servo motor drives the driving gear to rotate, thereby driving the driven gear and the detection rotor to rotate, and the speed measurement module measures the speed of the driving gear. The driving gear has the same speed as the detection rotor, and the speed of the detection rotor is indirectly detected. Through this setting, a set of detection parts can be used to control multiple detection rotors to work, and the function of monitoring the speed of multiple detection rotors can be realized. Compared with using multiple sets of detection parts, this setting is also cheaper.

[0011] Preferably, a driving box is provided at the front end of the regulating box, and the length of the driving box is longer than that of the regulating box. A screw nut mechanism 2 arranged along the length direction of the driving box is installed at one end of the driving box facing the regulating box, and a vertically arranged electric telescopic rod 3 is fixedly connected to the movable end of the screw nut mechanism 2, and the movable end of the electric telescopic rod 3 is fixedly connected to the electric heating tray. The electric heating tray is controlled to move horizontally along the length direction of the regulating box by the screw nut mechanism 2. Since the length of the driving box and the screw nut mechanism 2 is longer than the regulating box, the electric heating tray can be moved to the outside of the regulating box, which is convenient for placing and removing the detection tank. The lifting and lowering of the electric heating tray is controlled by extending and shortening the vertical electric telescopic rod 3.

[0012] Preferably, a plurality of access holes are provided at the front end recess of the control box, the positions of the access holes are adapted to the positions of the plurality of detection rotors, a plurality of cleaning pipes capable of being raised and lowered are provided inside the control box, and a water supply tank for transmitting water to the plurality of cleaning pipes is provided at the front end bottom of the control box. Since the surface of the previous detection rotor is often covered with resin each time the detection rotor is switched, in order not to contaminate the device, when the electric heating tray is removed, the cleaning pipe at the bottom moves upward and is sleeved on the outside of the detection rotor to prevent the resin from leaking to the outside of the device, and the pipe is also sleeved on the outside when the device is not being cleaned. The outside of the detection rotor is inspected to reduce the impact of the external environment on the detection rotor. After all the inspection work on the resin is completed, an appropriate amount of cleaning water is injected into the inside of the cleaning tube through the water supply tank, so that the resin on the surface of the detection rotor is slowly dissolved into the water, and the detection rotor is driven to rotate in turn to accelerate the dissolution speed, so that the resin on the surface of the detection rotor is peeled off cleanly. After that, the water supply tank recycles the cleaning water, and uses an electric heating tray to dry the detection rotor at the bottom. Finally, the cleaning tube is connected to the outside of the detection rotor, thereby realizing fully automatic processing of the detection rotor after use and reducing manual post-processing steps.

[0013] Preferably, a support seat is provided below the cleaning pipe, a regulating motor is fixedly connected to the top of the support seat, an output end of the regulating motor is fixedly connected to the top of the cleaning pipe, and a vertically arranged electric telescopic rod is fixedly connected to the top of the support seat, the electric telescopic rod controls the lifting and lowering of the support seat, and when the support seat is lowered to the bottom, the regulating motor controls the cleaning pipe to rotate to one side. This arrangement does not require the bottom of the regulating box to be set too high, allowing the cleaning pipe to effectively utilize the storage area inside the regulating box. At the same time, the cleaning pipe with an inclined top is not easy for foreign objects to fall into the inside.

After cleaning is completed, the solenoid valve is opened, the connecting valve connected to the external water pipe is closed, and the connecting valve connected to the drain pipe is opened. Under the action of gravity, the cleaned water is discharged from the drain pipe to complete the cleaning work.

In order to ensure the accuracy of the meshing process of the driving gear and the driven gear, when the driving gear is away from the driven gear, the linkage arm will be away from the connecting frame, and the connecting frame will push the fixed arm outward under the action of the spring, so that the arc-shaped fixed arm fits with the driven gear, so that the driven gear maintains its original posture. The servo motor will rotate the driving gear to a full integer number of circles in the final stage of rotation, which not only facilitates the measurement of the speed, but also ensures that each driven gear maintains the same state after stopping. When the driving gear approaches the driven gear, the linkage arm will squeeze the connecting frame, so that the connecting frame and the fixed arm retreat, so that the driven gear is released and can rotate normally. Through this arrangement, it is ensured that the driving gear and the driven gear can be meshed and transmitted normally.

[0016] A method for testing the viscosity of an unsaturated polyester resin, which is applicable to the unsaturated polyester resin viscosity testing device described above, and the method is specifically as follows:

[0017] S1: Put the resin to be tested into the test tank. The electric heating tray has a built-in heating wire, which can evenly heat the test tank from the bottom to keep the resin inside the test tank at a constant temperature.

[0018] S2: The electric heating tray can move horizontally and up and down to move the test tank to the bottom of the test rotor in the middle, and then rise to allow the test rotor to be inserted into the resin of the test tank. The test rotor in the middle is controlled to rotate by the servo motor;

[0019] S3: The viscosity of the resin will bring resistance to the rotation of the detection rotor, resulting in the detection rotor's rotation speed being affected under the same power consumption of the servo motor. The rotation speed of the detection rotor is monitored in real time through the speed measurement module, and then by comparing the normal rotation speed of the detection rotor without the influence of the resin, the viscosity value of the resin can be calculated.

[0020] The steps for detecting the rotation of the rotor described in S2 are as follows:

[0021] Q1: The positions of multiple detection rotors are limited by the restraining sleeve. When the detection rotor needs to rotate, the screw nut mechanism will first drive the entire servo motor and the driving gear to translate until the driving gear and the corresponding driven gear are aligned;

[0022] Q2: Then the electric telescopic rod 2 controls the driving gear to approach the driven gear and make them mesh with each other, and then the servo motor drives the driving gear to rotate, thereby driving the driven gear and the detection rotor to rotate;

[0023] Q3: The speed measurement module measures the speed of the driving gear. The speed of the driving gear is the same as that of the detection rotor, and the speed of the detection rotor is indirectly detected.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The unsaturated polyester resin viscosity testing device and testing method described in the present invention, through the setting of the control box and the electric heating tray, the resin to be tested is placed in the test tank, the electric heating tray has a built-in heating wire, which can evenly heat the test tank from the bottom to keep the resin inside the test tank at a constant temperature, the electric heating tray can move horizontally and up and down, move the test tank to the bottom of the test rotor located in the middle, and then rise, so that the test rotor is inserted into the resin in the test tank, and the test rotor located in the middle is controlled to rotate by the servo motor. Since the viscosity of the resin will bring resistance to the rotation of the test rotor, the rotation speed of the test rotor is affected under the same power consumption of the servo motor, the speed of the test rotor is monitored in real time by the speed measurement module, and then by comparing the normal speed of the test rotor without the influence of the resin, the viscosity value of the resin can be calculated. The number of the test rotors can be five, and the volume and surface of the five test rotors from one end to the other are the same. The area increases successively. The larger the surface area of ​​the detection rotor, the greater the influence of viscosity. It is used to detect resin solutions under different viscosities. First, the resin solution is detected by the detection rotor in the middle position. When the viscosity is detected for the first time, the position of the detection tank can be adjusted according to the viscosity value. The electric heating tray will transfer the detection tank to the bottom of another detection rotor for secondary detection. The purpose is to measure the viscosity of the resin more accurately. Since the viscosity of the resin changes with the change of temperature, in order to detect the viscosity value of the resin at different temperatures, the resin temperature is changed by the electric heating tray, and then the position of the detection tank is changed by the electric heating tray. Through this setting, the test process is effectively simplified, and there is no need to frequently replace the detection rotor. The viscosity of the resin in different states can also be detected. In the whole process, there is no need to manually touch the detection tank. The detection tank is always on the electric heating tray to ensure the constant temperature of the internal resin, thereby ensuring the accuracy of the detection data.

When a certain detection rotor needs to rotate, the screw nut mechanism 1 will first drive the entire servo motor and the driving gear to translate until the driving gear and the corresponding driven gear are aligned. Then the electric telescopic rod 2 controls the driving gear to approach the driven gear and make them mesh with each other. Then the servo motor drives the driving gear to rotate, and then drives the driven gear and the detection rotor to rotate. The speed measurement module measures the speed of the driving gear. The driving gear has the same speed as the detection rotor, and the speed of the detection rotor is indirectly detected. Through this setting, it is realized that one set of detection parts can be used to control multiple detection rotors to work and monitor the speed of multiple detection rotors. Compared with using multiple sets of detection parts, this setting cost is also lower. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figures 1 to 6 As shown, an unsaturated polyester resin viscosity testing device according to an embodiment of the present invention comprises a control box 1, the front end of the control box 1 is concave, a plurality of detection rotors 3 are arranged at the concave portion of the front end of the control box 1, the appearance and mass of the plurality of detection rotors 3 are different, the plurality of detection rotors 3 are linearly and equidistantly arranged, a detection tank 2 is arranged at the front end of the control box 1, the top of the detection tank 2 is open, an electric heating tray 5 for driving the detection tank 2 to move is arranged at the bottom of the detection tank 2, a servo motor 18 for controlling the rotation of the detection rotor 3 is arranged inside the control box 1, and a speed measurement module 17 for monitoring the speed of the detection rotor 3 is arranged inside the control box 1;

[0037] By setting up the control box 1 and the electric heating tray 5, the resin to be tested is placed in the test tank 2. The electric heating tray 5 has a built-in heating wire, which can evenly heat the test tank 2 from the bottom to keep the resin inside the test tank 2 at a constant temperature. The electric heating tray 5 can move horizontally and up and down to move the test tank 2 to the bottom of the test rotor 3 located in the middle, and then rise to allow the test rotor 3 to be inserted into the resin of the test tank 2. The test rotor 3 located in the middle is controlled to rotate by the servo motor 18. The viscosity of the resin will bring resistance to the rotation of the test rotor 3, resulting in the rotation speed of the test rotor 3 being affected under the same power consumption of the servo motor 18. The speed of the test rotor 3 is monitored in real time by the speed measurement module 17, and then by comparing the normal speed of the test rotor 3 without the influence of the resin, the viscosity value of the resin can be calculated. The number of the test rotors 3 can be five, and the volume and surface area of ​​the five test rotors 3 increase from one end to the other, and the surface area is The larger the detection rotor 3 is, the greater the influence of viscosity is. When used to detect resin solutions under different viscosities, the resin solution is first detected by the detection rotor 3 in the middle position. When the viscosity is detected for the first time, the position of the detection tank 2 can be adjusted according to the viscosity value. The electric heating tray 5 will transfer the detection tank 2 to the bottom of another detection rotor 3 for secondary detection. The purpose is to measure the viscosity of the resin more accurately. Since the viscosity of the resin changes with the change of temperature, in order to detect the viscosity value of the resin at different temperatures, the resin temperature is changed by the electric heating tray 5, and then the position of the detection tank 2 is changed by the electric heating tray 5. Through this setting, the test process is effectively simplified, and there is no need to frequently replace the detection rotor 3. The resin viscosity under different conditions can also be detected. In the whole process, there is no need to manually touch the detection tank 2. The detection tank 2 is always on the electric heating tray 5, which ensures the constant temperature of the internal resin, thereby ensuring the accuracy of the detection data.

[0038] The top of the detection rotor 3 is fixedly connected with a transmission shaft 25, the outer side of the transmission shaft 25 is sleeved with a restraining sleeve 26 fixedly connected to the control box 1, the top of the transmission shaft 25 is fixedly connected with a driven gear 21, the inside of the control box 1 is provided with a driving gear 19, the servo motor 18 is fixedly connected to the output end of the driving gear 19, the bottom detection end of the speed measurement module 17 is connected to the middle of the top surface of the driving gear 19, and the inner side of the control box 1 is provided with a lead screw nut mechanism 9 and two electric telescopic rods 16 for driving the servo motor 18 to move;

[0039] During operation, the positions of multiple detection rotors 3 are limited by the restraining sleeve 26. When a certain detection rotor 3 needs to rotate, the screw nut mechanism 1 9 will first drive the entire servo motor 18 and the driving gear 19 to translate until the driving gear 19 and the corresponding driven gear 21 are aligned. Then the electric telescopic rod 2 16 controls the driving gear 19 to approach the driven gear 21 and make them mesh with each other. Then the driving gear 19 is driven to rotate by the servo motor 18, and then the driven gear 21 and the detection rotor 3 are driven to rotate. The speed measurement module 17 measures the speed of the driving gear 19. The driving gear 19 has the same speed as the detection rotor 3, and the speed of the detection rotor 3 is indirectly detected. Through this setting, it is realized that a set of detection parts can be used to control multiple detection rotors 3 to work, and the speed of multiple detection rotors 3 can be monitored. Compared with using multiple sets of detection parts, this setting cost is also lower.

[0040] The moving ends of the two electric telescopic rods 16 are respectively fixed to the speed measurement module 17 and the servo motor 18, the two electric telescopic rods 16 are arranged in parallel up and down, the lead screw nut mechanism 9 is fixed to the inside of the control box 1 along the length direction of the control box 1, and a series seat 15 is fixed between the two electric telescopic rods 16, and the moving end of the lead screw nut mechanism 9 is fixed to the series seat 15;

[0041] When working, the screw nut mechanism 1 9 can drive the two electric telescopic rods 2 16 to translate along the length direction of the control box 1, so that the driving gear 19 is aligned with any driven gear 21, and the driving gear 19 is meshed and aligned with the aligned driven gear 21 through the extension of the electric telescopic rod 2 16; it should be noted that during the regulation process, the driving gear 19 needs to be moved away from the driven gear 21 before the subsequent translation process can be carried out.

[0042] A driving box 4 is provided at the front end of the regulating box 1. The length of the driving box 4 is longer than that of the regulating box 1. A screw nut mechanism 2 arranged along the length direction of the driving box 4 is installed at one end of the driving box 4 facing the regulating box 1. A vertically arranged electric telescopic rod 3 is fixedly connected to the moving end of the screw nut mechanism 2. The moving end of the electric telescopic rod 3 is fixedly connected to the electric heating tray 5.

[0043] During operation, the electric heating tray 5 is controlled by the screw nut mechanism 2 to move horizontally along the length direction of the control box 1. Since the length of the drive box 4 and the screw nut mechanism 2 is longer than the control box 1, the electric heating tray 5 can be moved to the outside of the control box 1, which is convenient for placing and removing the detection tank 2. The lifting and lowering of the electric heating tray 5 is controlled by the extension and shortening of the vertical electric telescopic rod 3.

[0044] A plurality of access holes 8 are provided at the front concave portion of the control box 1, and the positions of the access holes 8 match the positions of the plurality of detection rotors 3. A plurality of cleaning pipes 12 capable of being raised and lowered are provided inside the control box 1, and a water supply tank 6 for transmitting water to the plurality of cleaning pipes 12 is provided at the front bottom of the control box 1;

[0045] During operation, each time the detection rotor 3 is switched, the surface of the previous detection rotor 3 is often covered with resin. In order not to contaminate the device, after the electric heating tray 5 is removed, the cleaning pipe 12 at the bottom moves upward and is sleeved on the outside of the detection rotor 3 to prevent the resin from leaking to the outside of the device. When the device is not working, the cleaning pipe 12 is also sleeved on the outside of the detection rotor 3 to reduce the impact of the external environment on the detection rotor 3. After all the detection work on the resin is completed, an appropriate amount of cleaning water is injected into the cleaning pipe 12 through the water supply tank 6 to allow the resin on the surface of the detection rotor 3 to slowly dissolve into the water, and at the same time, the detection rotor 3 is driven to rotate in turn to accelerate the dissolution speed, so that the resin on the surface of the detection rotor 3 is peeled off cleanly. After that, the water supply tank 6 recovers the cleaning water, and the electric heating tray 5 is used to dry the detection rotor 3 at the bottom. Finally, the cleaning pipe 12 is sleeved on the outside of the detection rotor 3, thereby realizing fully automatic processing of the detection rotor 3 after use and reducing manual post-processing steps.

[0046] A support seat 11 is provided below the cleaning pipe 12, a regulating motor 14 is fixedly connected to the top of the support seat 11, an output end of the regulating motor 14 is fixedly connected to the top of the cleaning pipe 12, and a vertically arranged electric telescopic rod 10 is fixedly connected to the top of the support seat 11;

[0047] During operation, the electric telescopic rod 10 controls the lifting and lowering of the support seat 11. When the support seat 11 drops to the bottom, the regulating motor 14 controls the cleaning pipe 12 to rotate to one side. This arrangement does not require the bottom of the regulating box 1 to be set too high, allowing the cleaning pipe 12 to effectively utilize the storage area inside the regulating box 1. At the same time, the cleaning pipe 12 with an inclined top is not easy for foreign objects to fall into the inside.

[0048] Both ends of the water supply tank 6 are fixedly connected with connection valves 7, a water supply pipe 13 is connected between the bottom of the cleaning pipe 12 and the water supply tank 6, the water supply pipe 13 is spirally arranged, and a solenoid valve is connected between the water supply pipe 13 and the water supply tank 6;

[0049] During operation, a water pipe is required on the outside of the connecting valve 7, and the other connecting valve 7 is connected to the drain pipe. There is a certain water pressure in the water pipe. The other connecting valve 7 is in a closed state at the beginning. Water is injected into the designated water supply pipe 13 and the cleaning pipe 12 by opening the solenoid valve. After injecting an appropriate amount of water, the solenoid valve is closed. After cleaning is completed, the solenoid valve is opened, the connecting valve 7 connected to the external water pipe is closed, and the connecting valve 7 connected to the drain pipe is opened. Under the action of gravity, the cleaned water is discharged from the drain pipe to complete the cleaning work. The spiral water supply pipe 13 can be appropriately extended to adapt to the lifting process of the cleaning pipe 12.

[0050] A linkage arm 20 is fixedly connected to the side of the speed measurement module 17 facing the driven gear 21, a fixed arm 22 is arranged on the outer side of the driven gear 21, a connecting frame 24 is fixedly connected to the outer side of the fixed arm 22, a plurality of sleeves 23 are fixedly connected to the inside of the control box 1, the connecting frame 24 is slidably connected to the sleeves 23, and a spring is fixedly connected between the connecting frame 24 and the sleeves 23;

[0051] During operation, in order to ensure the accuracy of the meshing process of the driving gear 19 and the driven gear 21, when the driving gear 19 is away from the driven gear 21, the linkage arm 20 will be away from the connecting frame 24, and the connecting frame 24 will push the fixed arm 22 outward under the action of the spring, so that the arc-shaped fixed arm 22 fits with the driven gear 21, so that the driven gear 21 maintains its original posture. The servo motor 18 will rotate to the final stage and let the driving gear 19 rotate a full integer number of circles, which is not only convenient for measuring the speed, but also ensures that each driven gear 21 maintains the same state after stopping. When the driving gear 19 is close to the driven gear 21, the linkage arm 20 will squeeze the connecting frame 24, so that the connecting frame 24 and the fixed arm 22 retreat, so that the driven gear 21 can be released and rotate normally. Through this arrangement, it is ensured that the driving gear 19 and the driven gear 21 can be meshed and transmitted normally.

[0052] A method for testing the viscosity of an unsaturated polyester resin, which is applicable to the unsaturated polyester resin viscosity testing device described above, and the method is specifically as follows:

[0053] S1: Put the resin to be tested into the test tank 2. The electric heating tray 5 has a built-in heating wire, which can evenly heat the test tank 2 from the bottom to keep the resin inside the test tank 2 at a constant temperature;

[0054] S2: The electric heating tray 5 can move horizontally and vertically to move the detection tank 2 to the bottom of the detection rotor 3 located in the middle, and then rise to allow the detection rotor 3 to be inserted into the resin of the detection tank 2, and the detection rotor 3 located in the middle is controlled to rotate by the servo motor 18;

[0055] S3: Since the viscosity of the resin will bring resistance to the rotation of the detection rotor 3, the rotation speed of the detection rotor 3 is affected under the same power consumption of the servo motor 18. The rotation speed of the detection rotor 3 is monitored in real time by the rotation speed measurement module 17, and then by comparing the normal rotation speed of the detection rotor 3 without the influence of the resin, the viscosity value of the resin can be calculated.

[0056] The steps for detecting the rotation of the rotor 3 described in S2 are specifically as follows:

[0057] Q1: The positions of multiple detection rotors 3 are limited by the restraining sleeve 26. When the detection rotor 3 needs to rotate, the screw nut mechanism 9 will first drive the entire servo motor 18 and the driving gear 19 to translate until the driving gear 19 and the corresponding driven gear 21 are aligned;

[0058] Q2: Then the electric telescopic rod 16 controls the driving gear 19 to approach the driven gear 21 and make them mesh with each other, and then the servo motor 18 drives the driving gear 19 to rotate, thereby driving the driven gear 21 and the detection rotor 3 to rotate;

[0059] Q3: The speed measurement module 17 measures the speed of the driving gear 19 . The speed of the driving gear 19 is the same as that of the detection rotor 3 , and the speed of the detection rotor 3 is indirectly detected.

[0060] During operation, the resin to be tested is placed in the test tank 2 through the setting of the control box 1 and the electric heating tray 5. The electric heating tray 5 has a built-in heating wire, which can evenly heat the test tank 2 from the bottom to keep the resin inside the test tank 2 at a constant temperature. The electric heating tray 5 can move horizontally and up and down to move the test tank 2 to the bottom of the test rotor 3 located in the middle, and then rise to allow the test rotor 3 to be inserted into the resin in the test tank 2. The test rotor 3 located in the middle is controlled to rotate by the servo motor 18. The viscosity of the resin will bring resistance to the rotation of the test rotor 3, resulting in the detection rotor 3 The rotation speed is affected under the same power consumption of the servo motor 18, and the speed of the test rotor 3 is monitored in real time through the speed measurement module 17. By comparing the normal speed of the test rotor 3 without the influence of the resin, the viscosity value of the resin can be calculated. The number of the test rotors 3 can be five, and the volume and surface area of ​​the five test rotors 3 increase from one end to the other. The larger the surface area of ​​the detection rotor 3, the greater the influence of viscosity. To detect resin solutions with different viscosities, the resin solution is first detected by the detection rotor 3 in the middle position. When the viscosity is detected for the first time, the position of the detection tank 2 can be adjusted according to the viscosity value. The electric heating tray 5 will transfer the detection tank 2 to the bottom of another detection rotor 3 for secondary detection. The purpose is to measure the viscosity of the resin more accurately. Since the viscosity of the resin changes with the change of temperature, in order to detect the viscosity value of the resin at different temperatures, the resin temperature is changed by the electric heating tray 5, and then the position of the detection tank 2 is changed by the electric heating tray 5. Through this setting, the test process is effectively simplified, and the detection rotor 3 does not need to be frequently replaced. The viscosity of the resin in different states can also be detected. In the whole process, there is no need to manually touch the detection tank 2. The detection tank 2 is always on the electric heating tray 5, which ensures the constant temperature of the internal resin, thereby ensuring the accuracy of the detection data.

[0061] The positions of the multiple detection rotors 3 are limited by the restraining sleeve 26. When a certain detection rotor 3 needs to rotate, the lead screw nut mechanism 1 9 will first drive the entire servo motor 18 and the driving gear 19 to translate until the driving gear 19 and the corresponding driven gear 21 are aligned. Then the electric telescopic rod 2 16 controls the driving gear 19 to approach the driven gear 21 and make them mesh with each other. Then the servo motor 18 drives the driving gear 19 to rotate, and then drives the driven gear 21 and the detection rotor 3 to rotate. The speed measurement module 17 measures the speed of the driving gear 19. The driving gear 19 has the same speed as the detection rotor 3, and the speed of the detection rotor 3 is indirectly detected. Through this setting, it is realized that using one set of detection parts can control multiple detection rotors 3 to work, and the function of monitoring the speed of multiple detection rotors 3 is realized. Compared with using multiple sets of detection parts, this setting cost is also lower;

[0062] The lead screw nut mechanism 1 9 can drive the two electric telescopic rods 2 16 to translate along the length direction of the control box 1, so that the driving gear 19 is aligned with any driven gear 21, and the driving gear 19 is meshed and aligned with the aligned driven gear 21 through the extension of the electric telescopic rod 2 16; it should be noted that during the regulation process, the driving gear 19 needs to be moved away from the driven gear 21 before the subsequent translation process can be carried out;

[0063] The electric heating tray 5 is controlled to move horizontally along the length direction of the control box 1 by the screw nut mechanism 2. Since the length of the drive box 4 and the screw nut mechanism 2 is longer than the control box 1, the electric heating tray 5 can be moved to the outside of the control box 1, which is convenient for placing and removing the test tank 2. The lifting and lowering of the electric heating tray 5 is controlled by the extension and shortening of the vertical electric telescopic rod 3;

[0064] Since the surface of the previous detection rotor 3 is often covered with resin each time the detection rotor 3 is switched, in order not to contaminate the device, after the electric heating tray 5 is removed, the cleaning pipe 12 at the bottom moves upward and is sleeved on the outside of the detection rotor 3 to prevent the resin from leaking to the outside of the device. When the device is not working, the cleaning pipe 12 is also sleeved on the outside of the detection rotor 3 to reduce the impact of the external environment on the detection rotor 3. After all the detection work on the resin is completed, an appropriate amount of cleaning water is injected into the cleaning pipe 12 through the water supply tank 6 to allow the resin on the surface of the detection rotor 3 to slowly dissolve into the water, and at the same time, the detection rotor 3 is driven to rotate in turn to accelerate the dissolution speed, so that the resin on the surface of the detection rotor 3 is peeled off cleanly, and then the water supply tank 6 recovers the cleaning water, and the electric heating tray 5 is used to dry the detection rotor 3 at the bottom, and finally the cleaning pipe 12 is sleeved on the outside of the detection rotor 3, thereby realizing the fully automatic processing of the detection rotor 3 after use and reducing the manual post-processing steps;

[0065] The electric telescopic rod 10 controls the lifting of the support seat 11. When the support seat 11 is lowered to the bottom, the regulating motor 14 controls the cleaning pipe 12 to rotate to one side. This arrangement does not require the bottom of the regulating box 1 to be set too high, so that the cleaning pipe 12 can effectively utilize the storage area inside the regulating box 1. At the same time, the cleaning pipe 12 with an inclined top is not easy to let foreign matter fall into the inside;

[0066] The outer side of the connecting valve 7 needs a water pipe, and the other connecting valve 7 is connected to the drain pipe. There is a certain water pressure in the water pipe. The other connecting valve 7 is in a closed state at the beginning. Water is injected into the designated water supply pipe 13 and the cleaning pipe 12 by opening the solenoid valve. After injecting a proper amount of water, the solenoid valve is closed. After the cleaning is completed, the solenoid valve is opened, the connecting valve 7 connected to the external water pipe is closed, and the connecting valve 7 connected to the drain pipe is opened. Under the action of gravity, the cleaned water is discharged from the drain pipe to complete the cleaning work. The spiral water supply pipe 13 can be appropriately extended to adapt to the lifting process of the cleaning pipe 12;

[0067] In order to ensure the accuracy of the meshing process of the driving gear 19 and the driven gear 21, when the driving gear 19 is away from the driven gear 21, the linkage arm 20 will be away from the connecting frame 24, and the connecting frame 24 will push the fixed arm 22 outward under the action of the spring, so that the arc-shaped fixed arm 22 fits with the driven gear 21, so that the driven gear 21 maintains its original posture. The servo motor 18 will rotate to the final stage and let the driving gear 19 rotate a full integer number of circles, which is not only convenient for the measurement of the rotation speed, but also ensures that each driven gear 21 maintains the same state after stopping. When the driving gear 19 approaches the driven gear 21, the linkage arm 20 will squeeze the connecting frame 24, so that the connecting frame 24 and the fixed arm 22 retreat, so that the driven gear 21 can be released and rotate normally. Through this arrangement, it is guaranteed that the driving gear 19 and the driven gear 21 can be meshed and transmitted normally.
