Description

Technical Field

[0001] This invention relates to the field of new material testing technology, specifically to a viscosity testing device for testing new dyeing and printing auxiliaries. Background Technology

[0002] In the performance testing of new dyeing and printing auxiliaries, viscosity is one of the core indicators. Its testing accuracy directly affects the production, application, and quality control of dyeing and printing auxiliaries. Rotary viscosity testing devices have become commonly used equipment for viscosity testing of new dyeing and printing auxiliaries due to their accurate testing and strong adaptability. To ensure the accuracy of the test data, such viscosity testing devices must perform self-calibration of the torque detection-related sensors before each formal testing operation to eliminate the equipment's own errors and ensure the reliability of subsequent viscosity testing results for dyeing and printing auxiliaries. The existing self-testing method of rotary viscosity testing devices usually involves directly immersing the core testing components, such as the testing shaft and stirring shaft, in a standard viscosity solution to complete the self-test. This method causes the standard viscosity solution to adhere directly to the outer surface of the testing shaft and stirring shaft, leaving residue. Since the residual standard viscosity solution can contaminate the dyeing and printing auxiliaries to be tested and interfere with the acquisition of torque values ​​in the formal test, it will affect the accuracy of viscosity testing. Therefore, after the self-test, the testing shaft and stirring shaft must be thoroughly cleaned until there is no standard viscosity solution residue on their surfaces before they can be used for the formal viscosity testing of dyeing and printing auxiliaries. This cleaning step not only increases the pre-testing operation procedures but also significantly extends the testing interval time, reducing the overall testing efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a viscosity testing device for detecting new dyeing and printing auxiliaries, thus solving the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a viscosity testing device for detecting new dyeing and printing auxiliaries, comprising a testing platform and a viscosity testing component. A lifting electric push rod is fixed to one side of the surface of the testing platform, and a mounting platform is fixed to the top of the lifting electric push rod. The viscosity testing component includes a drive motor fixed to the end of the mounting platform, and a torque sensor is connected to the bottom of the drive motor. A self-testing shaft is connected to the bottom of the torque sensor, and a threaded section is provided at the bottom of the self-testing shaft. A self-testing stirring paddle is inserted into the bottom of the threaded section. A limiting piece is fixed to the bottom outer wall of the threaded section. The self-testing shaft is threadedly connected to a connecting pipe through the threaded section, and a magnetic suction piece is provided on the top of the connecting pipe. A fixing magnetic piece is fixed above the magnetic suction piece on the bottom surface of the mounting platform. A plug-in sleeve is provided on the bottom outer wall of the connecting pipe, and a detection stirring shaft is inserted into the hole at the bottom of the plug-in sleeve. A self-testing cavity is opened inside the detection stirring shaft, and a plug-in hole is provided on the lower inner wall of the detection stirring shaft. A sealing cap is inserted into the bottom end of the detection stirring shaft. A telescopic liquid injection hose is passed through the surface of the detection platform on one side of the lifting electric push rod.

[0005] Furthermore, the top end of the telescopic injection hose is provided with an injection connector, and the injection connector can be plugged into the insertion hole.

[0006] Furthermore, the end of the telescopic injection hose away from the injection connector is connected to a bidirectional pump, and the end of the bidirectional pump away from the telescopic injection hose is connected to a standard viscosity tank. The standard viscosity tank stores a standard viscosity liquid with a preset viscosity value that is easy to clean. The standard viscosity liquid is a polyvinyl alcohol (PVA) aqueous solution standard solution, which can be cleaned by rinsing with warm water.

[0007] Furthermore, the outer diameter of the self-testing agitator is smaller than the inner diameter of the self-testing cavity inside the connecting pipe and the testing agitator shaft, and the self-testing agitator is located inside the connecting pipe.

[0008] Furthermore, the inside of the connecting tube is connected to the self-testing chamber inside the stirring shaft, and the connecting tube can be magnetically attracted and connected to the fixed magnetic sheet through a magnetic absorbing plate.

[0009] Furthermore, the outer diameter of the limiting piece is smaller than the inner diameter of the connecting pipe, and the upper surface of the limiting piece is in contact with the top surface of the inner wall of the connecting pipe.

[0010] Furthermore, a testing container is mounted on the surface of the testing platform, and the testing container contains a dyeing and printing auxiliary agent for which viscosity testing is to be performed.

[0011] Furthermore, horizontal electric push rods are symmetrically fixed at both ends of the surface of the testing stage, and V-shaped clamps are connected to the ends of the horizontal electric push rods.

[0012] Furthermore, the V-shaped surfaces of the V-shaped clamps are fitted to both sides of the detection container, and the V-shaped clamps extend and retract synchronously.

[0013] This invention provides a viscosity testing device for detecting new dyeing and printing auxiliaries, which has the following beneficial effects: 1. This viscosity testing device for new dyeing and printing auxiliary materials raises the connecting tube along its threaded section by screwing it in. The magnetic attraction between the magnetic plate and the fixed magnetic plate secures the connecting tube, allowing the self-testing agitator to extend into the self-testing chamber of the testing agitator shaft. A standard viscosity liquid is then injected into the self-testing chamber using a telescopic injection hose. The drive motor rotates the self-testing agitator, and the torque sensor completes its self-test and corrects the coefficient based on the measured value, effectively ensuring the accuracy of subsequent viscosity testing. After the self-test is complete, the connecting tube is pulled down and screwed in to descend along its threaded section to the limit plate. The device is positioned so that the lifting electric push rod drives the testing stirring shaft to extend into the testing container of the dyeing and printing auxiliaries. The drive motor can drive the connecting pipe to rotate synchronously with the testing stirring shaft. The torque sensor detects the viscosity of the dyeing and printing auxiliaries by detecting the torque value. During the self-test, the standard viscosity liquid only remains in the self-test chamber inside the testing stirring shaft. The outer wall of the testing stirring shaft does not come into contact with the standard viscosity liquid. Therefore, after the self-test is completed, there is no need to clean the testing stirring shaft of the standard viscosity liquid. The viscosity test of the dyeing and printing auxiliaries can be carried out directly, which greatly simplifies the operation process before the test and improves the overall testing efficiency.

[0014] 2. The viscosity testing device for this new material testing of printing and dyeing auxiliaries features a plug-in connection between the testing stirring shaft and the bottom of the connecting pipe, as well as a plug-in connection between the self-testing stirring paddle and the threaded section at the bottom of the self-testing shaft. After viscosity testing, the testing stirring shaft and self-testing stirring paddle can be quickly disassembled and reassembled manually, allowing for timely replacement of new parts for the next testing operation and effectively shortening the testing interval. Simultaneously, the standard viscosity liquid on the replaced parts is a polyvinyl alcohol (PVA) aqueous solution. Residual standard liquid on the outer wall of the self-testing stirring paddle and the inner wall of the self-testing chamber of the testing stirring shaft can be cleaned simply by rinsing with warm water. This cleaning method is simple and convenient, requiring no special cleaning reagents, thus reducing cleaning costs and operational difficulty. When cleaning the printing and dyeing auxiliaries residue on the outer wall of the testing stirring shaft, the top opening can be sealed with a cap, allowing for targeted cleaning only of the outer wall. This avoids contamination of the self-testing chamber and further improves the targeting and efficiency of residue cleaning. Attached Figure Description

Detailed Implementation

[0017] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0018] like Figures 1-5As shown, the present invention provides a technical solution: a viscosity testing device for testing new dyeing and printing auxiliaries, comprising a testing platform 1 and a viscosity testing component 4. A lifting electric push rod 2 is fixed to one side of the surface of the testing platform 1, and a mounting platform 3 is fixed to the top of the lifting electric push rod 2. The viscosity testing component 4 includes a drive motor 401 fixed to the end of the mounting platform 3, and a torque sensor 402 is connected to the bottom of the drive motor 401. A self-testing shaft 403 is connected to the bottom of the torque sensor 402, and a threaded section 404 is provided at the bottom of the self-testing shaft 403. The bottom of the threaded section 404 is inserted into... A self-testing stirring paddle 405 is connected to the bottom outer wall of the threaded section 404, and a limiting piece 406 is fixed thereon. The self-testing shaft 403 is threadedly connected to a connecting pipe 407 through the threaded section 404, and a magnetic suction piece 408 is provided on the top of the connecting pipe 407. A fixing magnetic piece 409 is fixed on the bottom surface of the mounting platform 3 above the magnetic suction piece 408. A plug-in sleeve 410 is provided on the bottom outer wall of the connecting pipe 407, and a test stirring shaft 411 is inserted into the bottom hole of the plug-in sleeve 410. A self-testing cavity 412 is opened inside the test stirring shaft 411, and a plug-in hole is provided on the lower inner wall of the test stirring shaft 411. 413. A sealing cap 414 is inserted into the bottom end of the stirring shaft 411. A telescopic injection hose 415 is inserted through the surface of the testing platform 1 on one side of the lifting electric push rod 2. An injection connector is provided at the top end of the telescopic injection hose 415, and the injection connector can be inserted into the insertion hole 413. A two-way pump is connected to the end of the telescopic injection hose 415 away from the injection connector, and a standard viscosity tank is connected to the end of the two-way pump away from the telescopic injection hose 415. The standard viscosity tank stores a standard viscosity liquid with a preset viscosity value that is easy to clean. The standard viscosity liquid is polyvinyl alcohol (PVA). A standard aqueous solution can be cleaned by rinsing with warm water. The outer diameter of the self-testing stirring paddle 405 is smaller than that of the connecting pipe 407 and the inner diameter of the self-testing cavity 412 inside the testing stirring shaft 411. The self-testing stirring paddle 405 is located inside the connecting pipe 407. The inside of the connecting pipe 407 is connected to the self-testing cavity 412 inside the testing stirring shaft 411. The connecting pipe 407 can be magnetically attracted to the fixed magnetic sheet 409 through the magnetic suction piece 408. The outer diameter of the limiting piece 406 is smaller than that of the inner diameter of the connecting pipe 407. The upper surface of the limiting piece 406 is in contact with the top surface of the inner wall of the connecting pipe 407. The specific operation is as follows: Before testing the viscosity of the dyeing and printing auxiliaries in the test container 5, when the test container 5 is not placed on the surface of the test table 1, manually twist the connecting tube 407 to make it rotate and rise along the outer wall of the threaded section 404. After the connecting tube 407 is separated from the threaded section 404, lift it directly until the magnetic suction plate 408 and the fixed magnetic plate 409 are magnetically attracted and connected. At this time, the self-testing stirring paddle 405 descends in disguise and extends into the self-testing cavity 412 of the test stirring shaft 411. Then, the sealing cap 414 is manually opened to expose the insertion hole 413. The telescopic injection hose 415 is then manually pulled out to connect the injection connector to the insertion hole 413. The standard viscosity liquid stored in the standard viscosity tank is then quantitatively injected into the self-test chamber 412 by a bidirectional pump. The self-test stirring paddle 405 is submerged in the standard viscosity liquid, and the limiting plate 406 is positioned at the limit position. Then, the drive motor 401 is started to drive the torque sensor 402 to drive the self-test shaft 403 and the threaded section 404, so that the self-test stirring paddle 405 rotates in the standard viscosity liquid at a preset speed. The torque sensor 402 detects the value to complete the self-test. If the error between the value and the standard viscosity liquid value is within the allowable threshold, the self-test is normal. Otherwise, the coefficient of the torque sensor 402 needs to be corrected. The detection stirring shaft 411 does not rotate because it is inserted into the connecting pipe 407 and magnetically attracted to the fixed magnet 409 through the magnetic suction plate 408. After the self-test is completed, the bidirectional pump reverses its operation to discharge the standard viscosity liquid inside the self-test chamber 412 back to the standard viscosity tank. Then, the sealing cap 414 is reinserted to seal the insertion hole 413. The connecting tube 407 is then pulled down to separate the magnetic suction plate 408 from the fixed magnetic plate 409. The connecting tube 407 is then twisted to rotate and descend along the outer wall of the threaded section 404 until the top of the inner wall of the connecting tube 407 is limited by the limiting plate 406. The rotation of the connecting tube 407 as it descends along the outer wall of the threaded section 404 is in the same direction as the rotation of the detection stirring shaft 411 driven by the drive motor 401. Then, the test container 5 is placed directly below the self-testing stirring paddle 405. The retraction of the lifting electric push rod 2 drives the test stirring shaft 411 to descend and extend into the test container 5 until the test stirring shaft 411 is submerged in the dyeing and printing auxiliary agent to be tested. The part of the test stirring shaft 411 that is inserted into the connecting tube 407 is above the auxiliary agent but does not contact it. At this time, the drive motor 401 drives the threaded section 404 to rotate, and the connecting tube 407, which is threaded to the threaded section 404, carries the test stirring shaft 411 in the auxiliary agent and rotates at a preset speed. During this process, the value is detected by the torque sensor 402, thereby realizing the viscosity detection of the dyeing and printing auxiliary agent. After the viscosity test is completed, the test container 5 is removed and the additives inside are poured out. At this time, the residue will adhere to the inner wall of the test container 5 and the outer wall of the test stirring shaft 411. In order to quickly prepare for the next viscosity test, the test stirring shaft 411 is manually pulled out to separate it from the connecting pipe 407. The self-testing stirring paddle 405 is also pulled out to separate it from the threaded section 404. A new test stirring shaft 411 and a new self-testing stirring paddle 405 are then installed. The replaced self-testing stirring paddle 405, test stirring shaft 411 and test container 5 are sent to the cleaning area together. When cleaning the residue on the outer wall of the testing stirring shaft 411 and the inner wall of the testing container 5, the corresponding cleaning method is selected based on the composition of the residue. During the process, the top opening of the testing stirring shaft 411 needs to be sealed with a cap to prevent the self-testing chamber 412 from being exposed. This means cleaning the auxiliary residue on the outer wall of the testing stirring shaft 411. After that, the residue of the marked viscosity liquid on the inner wall of the self-testing chamber 412 and the outer wall of the self-testing stirring paddle 405 is rinsed. The marked viscosity liquid is a standard solution of polyvinyl alcohol (PVA) aqueous solution, which can be cleaned by rinsing with warm water. Based on the above description, the present invention raises the connecting tube 407 along the threaded section 404 by twisting the connecting tube 407, and uses the magnetic attraction of the magnetic absorbing plate 408 and the fixed magnetic plate 409 to lift and fix the connecting tube 407. At this time, the self-testing stirring paddle 405 can be inserted into the self-testing chamber 412 of the testing stirring shaft 411. With the help of the telescopic liquid injection hose 415, a standard viscosity liquid is injected into the self-testing chamber 412. After the drive motor 401 drives the self-testing stirring paddle 405 to rotate, the torque sensor 402 can complete the self-test and correct the coefficient according to the detection value, effectively ensuring the accuracy of subsequent viscosity detection. After the self-test is completed, the connecting tube 407 is pulled down and twisted to lower it to the limit along the threaded section 404. The plate 406 is positioned, and then the lifting electric push rod 2 drives the detection stirring shaft 411 to extend into the detection container 5 to detect the dyeing auxiliary agent. The drive motor 401 can drive the connecting pipe 407 to rotate synchronously with the detection stirring shaft 411. The torque sensor 402 detects the viscosity of the dyeing auxiliary agent by detecting the torque value. During the self-test, the standard viscosity liquid is only left in the self-test chamber 412 inside the detection stirring shaft 411. The outer wall of the detection stirring shaft 411 does not come into contact with the standard viscosity liquid. Therefore, after the self-test is completed, there is no need to clean the standard viscosity liquid from the detection stirring shaft 411. The viscosity test of the dyeing auxiliary agent can be carried out directly, which greatly simplifies the operation process before the test and improves the overall test efficiency. Furthermore, the insertion sleeve 410 at the bottom of the testing stirring shaft 411 and the connecting pipe 407 is a plug-in connection, and the threaded section 404 at the bottom of the self-testing stirring paddle 405 and the self-testing shaft 403 is also a plug-in connection. After the viscosity test is completed, the testing stirring shaft 411 and the self-testing stirring paddle 405 can be quickly disassembled and assembled by manual unplugging, allowing for timely replacement of new parts for the next test operation, effectively shortening the test interval time. At the same time, the standard viscosity liquid on the replaced parts is a polyvinyl alcohol (PVA) aqueous solution standard solution. The standard solution remaining on the outer wall of the self-testing stirring paddle 405 and the inner wall of the self-testing chamber 412 of the testing stirring shaft 411 can be cleaned simply by rinsing with warm water. The cleaning method is simple and convenient, without the need for special cleaning reagents, reducing cleaning costs and operational difficulty. When cleaning the dyeing auxiliary agent residue on the outer wall of the testing stirring shaft 411, its top opening can be sealed by sealing the cap, allowing for targeted cleaning of only its outer wall. This avoids contamination of the self-testing chamber 412 and further improves the targeting and efficiency of residue cleaning.

[0019] like Figures 1-5 As shown, a test container 5 is placed on the surface of the test table 1, and the test container 5 contains a dyeing and printing auxiliary agent to be tested for viscosity. Horizontal electric push rods 6 are symmetrically fixed at both ends of the surface of the test table 1, and V-shaped clamps 7 are connected to the ends of the horizontal electric push rods 6. The V-shaped surfaces of the V-shaped clamps 7 are attached to both sides of the test container 5, and the V-shaped clamps 7 extend and retract synchronously. The specific operation is as follows: the dyeing and printing auxiliary agent to be tested is quantitatively placed into the test container 5, the test container 5 is placed on the surface of the test stage 1 and positioned between the V-shaped clamps 7, and then the horizontal electric push rod 6 extends to drive the two V-shaped clamps 7 to extend synchronously. When the V-shaped clamps 7 extend synchronously, their V-shaped surfaces are attached to both sides of the test container 5, and the test container 5 is pushed in the subsequent pushing process to adjust its own position so that after the test container 5 is clamped and stabilized, it can be positioned directly below the self-testing stirring paddle 405, and the vertical central axes of the two can coincide.

[0020] In summary, when using this viscosity testing device for new dyeing and printing auxiliary materials, the dyeing and printing auxiliary to be tested is first quantitatively placed into the testing container 5. The testing container 5 is then placed on the surface of the testing platform 1 and positioned between the V-shaped clamps 7. Then, the horizontal electric push rod 6 extends to drive the two V-shaped clamps 7 to extend synchronously. When the V-shaped clamps 7 extend synchronously, their V-shaped surfaces are in contact with both sides of the testing container 5. During the subsequent pushing process, the testing container 5 is pushed to adjust its own position so that after the testing container 5 is clamped and stabilized, it can be positioned directly below the self-testing stirring paddle 405, and the vertical central axes of the two can coincide. Before testing the viscosity of the dyeing and printing auxiliaries in the test container 5, when the test container 5 is not placed on the surface of the test table 1, manually twist the connecting pipe 407 to make it rotate and rise along the outer wall of the threaded section 404. After the connecting pipe 407 is separated from the threaded section 404, lift it directly until the magnetic suction plate 408 and the fixed magnetic plate 409 are magnetically attracted and connected. At this time, the self-testing stirring paddle 405 descends in disguise and extends into the self-testing cavity 412 of the test stirring shaft 411. Then, the sealing cap 414 is manually opened to expose the insertion hole 413. The telescopic injection hose 415 is then manually pulled out to connect the injection connector to the insertion hole 413. The standard viscosity liquid stored in the standard viscosity tank is then quantitatively injected into the self-test chamber 412 by a bidirectional pump. The self-test stirring paddle 405 is submerged in the standard viscosity liquid, and the limiting plate 406 is positioned at the limit position. Then, the drive motor 401 is started to drive the torque sensor 402 to drive the self-test shaft 403 and the threaded section 404, so that the self-test stirring paddle 405 rotates in the standard viscosity liquid at a preset speed. The torque sensor 402 detects the value to complete the self-test. If the error between the value and the standard viscosity liquid value is within the allowable threshold, the self-test is normal. Otherwise, the coefficient of the torque sensor 402 needs to be corrected. The detection stirring shaft 411 does not rotate because it is inserted into the connecting pipe 407 and magnetically attracted to the fixed magnet 409 through the magnetic suction plate 408. After the self-test is completed, the bidirectional pump reverses its operation to discharge the standard viscosity liquid inside the self-test chamber 412 back to the standard viscosity tank. Then, the sealing cap 414 is reinserted to seal the insertion hole 413. The connecting tube 407 is then pulled down to separate the magnetic suction plate 408 from the fixed magnetic plate 409. The connecting tube 407 is then twisted to rotate and descend along the outer wall of the threaded section 404 until the top of the inner wall of the connecting tube 407 is limited by the limiting plate 406. The rotation of the connecting tube 407 as it descends along the outer wall of the threaded section 404 is in the same direction as the rotation of the detection stirring shaft 411 driven by the drive motor 401. Then, the test container 5 is placed directly below the self-testing stirring paddle 405. The retraction of the lifting electric push rod 2 drives the test stirring shaft 411 to descend and extend into the test container 5 until the test stirring shaft 411 is submerged in the dyeing and printing auxiliary agent to be tested. The part of the test stirring shaft 411 that is inserted into the connecting tube 407 is above the auxiliary agent but does not contact it. At this time, the drive motor 401 drives the threaded section 404 to rotate, and the connecting tube 407, which is threaded to the threaded section 404, carries the test stirring shaft 411 in the auxiliary agent and rotates at a preset speed. During this process, the value is detected by the torque sensor 402, thereby realizing the viscosity detection of the dyeing and printing auxiliary agent. After the viscosity test is completed, the test container 5 is removed and the additives inside are poured out. At this time, the residue will adhere to the inner wall of the test container 5 and the outer wall of the test stirring shaft 411. In order to quickly prepare for the next viscosity test, the test stirring shaft 411 is manually pulled out to separate it from the connecting pipe 407. The self-testing stirring paddle 405 is also pulled out to separate it from the threaded section 404. A new test stirring shaft 411 and a new self-testing stirring paddle 405 are then installed. The replaced self-testing stirring paddle 405, test stirring shaft 411 and test container 5 are sent to the cleaning area together. When cleaning the residue on the outer wall of the testing stirring shaft 411 and the inner wall of the testing container 5, the corresponding cleaning method is selected based on the composition of the residue. During the process, the top opening of the testing stirring shaft 411 needs to be sealed with a cap to prevent the self-testing chamber 412 from being exposed, which means cleaning the auxiliary residue on the outer wall of the testing stirring shaft 411. Then, the residue of the marked viscosity liquid on the inner wall of the self-testing chamber 412 and the outer wall of the self-testing stirring paddle 405 is rinsed. The marked viscosity liquid is a standard solution of polyvinyl alcohol (PVA) aqueous solution, which can be cleaned by rinsing with warm water.
