Description

Technical Field

[0001] The present invention relates to the technical field of measuring the strength of hydrogel particles, and particularly relates to a device and method for measuring the strength of hydrogel particles. Background Art

[0002] Hydrogel particles are materials composed of hydrophilic polymers, and these particles can regulate the adsorption and transmission properties of the materials. They can be made of natural or synthetic polymers and can be given various shapes and sizes through a variety of preparation techniques, such as batch emulsion method, microfluidic emulsion method, photolithography method, electrohydrodynamic spraying method, and mechanical crushing method, etc. Hydrogel particles are widely used in fields such as cell culture, tissue engineering, and drug and protein delivery due to their high water content, properties similar to natural extracellular matrix, and diverse performances.

[0003] Gel strength is an important index reflecting the quality of the gel. For hydrogel particles, their strength directly affects their performance in practical applications. Through strength measurement, the mechanical properties and stability of the particles can be understood, thereby ensuring product quality.

[0004] Currently, before testing, the existing devices for measuring the strength of hydrogel particles rely on staff to inspect the hydrogel specimens, removing those with obvious defects and insufficient uniformity that do not meet the test standards. This process is time-consuming and laborious, and it is easy to cause misjudgment due to the eye fatigue problem of the staff, thus affecting the accuracy of subsequent detection results. Therefore, it is necessary to propose a device and method for measuring the strength of hydrogel particles that can automatically detect hydrogel particles. Summary of the Invention

[0005] To solve the above problems, the present invention provides a device and method for measuring the strength of hydrogel particles. By using a light beam emitter, a photodetector, and a controller, the refractive index of the hydrogel particles is judged, and based on this, whether the hydrogel particles have defects or insufficient hydrogel uniformity is judged.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A device and method for measuring the strength of hydrogel particles, including a box body. There is a feeding port opened at the top of the box body. A controller is fixedly connected to the surface of the box body. A fixing component for restricting the position of the hydrogel particles is provided inside the box body. An arranging component for arranging the hydrogel particles is provided between the fixing component and the feeding port. A pressing component for measuring the strength of the hydrogel particles is provided above the fixing component. A light beam emitter for emitting detection light is fixedly connected to the inner wall of the box body, and the light beam emitter is located between the fixing component and the pressing component. A photodetector for receiving the detection light is provided inside the fixing component.

[0007] The controller is used to input the standard refractive index when there are no bubbles in the hydrogel particles and the hydrogel is uniform.

[0008] The controller is used to determine the diameter of the hydrogel particles based on the positions of the light rays emitted by the light beam emitter and the light rays received by the photodetector.

[0009] The controller is used to determine the refractive index of the hydrogel particles on the fixing component based on the detection light rays emitted by the light beam emitter and the positions where the photodetector receives the detection light rays, and compare it with the standard refractive index. When the refractive index is the same as the standard refractive index, the controller will determine that the hydrogel particles meet the measurement requirements. When the refractive index is different from the standard refractive index, the controller will determine that the hydrogel does not meet the measurement requirements.

[0010] The technical principle of the above solution is as follows: The light beam emitter is responsible for emitting light rays. These light rays pass through the hydrogel particles. The photodetector is placed at the bottom of the hydrogel particles to capture and record the state of the light rays after passing through the hydrogel particles.

[0011] The refractive index is a measure of the refractive ability of a substance to light. Different substances have different refractive indices. When light rays enter the hydrogel particles from the air, the direction of the light rays will change. This phenomenon is called refraction. The degree of refraction depends on the refractive indices of the two media. The controller can calculate the refraction angle of the light rays when passing through the hydrogel particles by comparing the position differences between the light rays emitted by the light beam emitter and the light rays received by the photodetector.

[0012] When there are bubbles, impurities or insufficient uniformity inside the hydrogel particles, their refractive indices will change. The controller has pre-entered the standard refractive index when the hydrogel particles have no bubbles and the hydrogel is uniform.

[0013] In actual measurement, the controller compares the measured refractive index with the standard refractive index. If the two are the same, it indicates that the uniformity and quality of the hydrogel particles are good and meet the measurement requirements. If the difference between the two is large, it indicates that the hydrogel particles may have defects or insufficient uniformity and do not meet the measurement requirements.

[0014] The above solution has the following beneficial effects:

[0015] 1. Through the light beam emitter, photodetector and controller, the present invention realizes the automatic detection of hydrogel particles. This greatly reduces the time and labor costs of manual inspection, improves the detection efficiency, and makes the whole detection process more efficient and fast. The automatic detection also brings a significant improvement in detection accuracy. Since the whole detection process is completed by high-precision light beam emitter, photodetector and controller, it can reduce the errors caused by human factors and ensure the accuracy and consistency of the detection results. This is of great significance for the quality control of hydrogel particles, helps to detect potential quality problems in time, and ensures the stability and reliability of the products.

[0016] 2. Measuring the refractive index and diameter of hydrogel particles using optical principles has high precision. By comparing the measured refractive index with the standard refractive index, it is conducive to accurately evaluating the quality and uniformity of hydrogel particles. And this high-precision detection method helps to timely discover potential quality problems and provides a reliable basis for subsequent strength determination.

[0017] 3. The optical detection of the present invention will not cause physical damage to hydrogel particles, realizing non-destructive detection. This helps to retain the integrity of hydrogel particles for subsequent strength determination or other tests.

[0018] Furthermore, the arranging component includes a funnel. The top of the funnel is fixedly communicated with the feeding port. A transportation pipeline is fixedly connected to the bottom of the funnel. A solenoid valve is fixedly communicated inside the transportation pipeline. The controller is used to control the opening and closing of the solenoid valve. The end of the transportation pipeline away from the funnel corresponds to the fixing component.

[0019] Beneficial effects: The design of the funnel enables hydrogel particles to be concentrated and enter the transportation pipeline orderly, avoiding chaos and accumulation of particles during the feeding process.

[0020] Guided by the transportation pipeline, hydrogel particles can be neatly arranged inside the transportation pipeline. By controlling the opening and closing of the solenoid valve through the controller, the hydrogel particles are transported to the fixing component, providing convenience for subsequent strength determination.

[0021] Furthermore, the fixing component includes a telescopic plate. A plurality of first grooves are formed at the bottom of the telescopic plate. A first gear is rotatably connected to the bottom of the telescopic plate. A plurality of second grooves are formed on the first gear. Telescopic rods are slidably fitted in the first grooves respectively. The bottom ends of the telescopic rods are slidably fitted with the adjacent second grooves respectively.

[0022] Sliding blocks are fixedly connected to the ends of the telescopic rods away from the telescopic plate. The sliding blocks are all slidably fitted with the inner bottom wall of the box body.

[0023] Electric push rods are fixedly connected to the tops of the sliding blocks respectively. The controller is used to control the start and stop of the electric push rods. The output shafts of the electric push rods are fixedly connected with arc-shaped plates respectively.

[0024] A bearing plate is fixedly connected to the inner side wall of the box body. The bearing plate is located between the arc-shaped plate and the telescopic plate. A plurality of first openings are formed on the bearing plate. The electric push rods all penetrate through the first openings and are slidably fitted with the first openings.

[0025] The first gear meshes with a second gear. The second gear is rotatably connected with the telescopic plate. A power component is provided at the bottom of the second gear for driving the second gear to rotate.

[0026] Beneficial effects: By judging the diameter of the hydrogel particles by the controller, the controller can adjust the rotation angle of the power assembly and the elongation degree of the electric push rod according to the diameter of the hydrogel particles, thereby realizing the movement and fixation of the arc-shaped plate, and improving the accuracy and efficiency of fixation.

[0027] The sliding fit between the sliding block and the inner bottom wall of the box body, and the sliding fit between the arc-shaped plate and the first opening on the bearing plate ensure the stability of the fixing assembly during the movement.

[0028] Furthermore, the power assembly includes a driving motor, the output shaft of the driving motor is coaxially and fixedly connected to the second gear, the driving motor is fixedly connected to the inner bottom wall of the box body, and the controller is used to control the start and stop of the driving motor.

[0029] Beneficial effects: The output shaft of the driving motor is coaxially and fixedly connected to the second gear, ensuring the accuracy of transmission. When the driving motor starts, the second gear will rotate at a predetermined speed and direction, and then drive the movement of the first gear and the telescopic rod, realizing the precise fixation of the hydrogel particles.

[0030] Furthermore, the pressurizing assembly includes an electric extrusion plate, a pressure sensor is fixedly connected to the bottom of the electric extrusion plate, and the controller is used to receive the pressure data monitored by the pressure sensor; the controller is used to control the lifting of the electric extrusion plate. When it is necessary to measure the strength of the hydrogel particles, the controller controls the electric extrusion plate to descend. When it is necessary to stop measuring the strength of the hydrogel particles, the controller controls the electric extrusion plate to rise. A support block is fixedly connected to the top of the electric extrusion plate, and an adjusting assembly for adjusting the position of the support block is provided on the top of the support block.

[0031] Beneficial effects: The hydrogel particles are extruded by the electric extrusion plate, and the pressure condition received by the hydrogel particles is judged by the pressure sensor, thereby judging the strength of the hydrogel particles.

[0032] The electric extrusion plate can accurately adjust the height through the controller, improving the accuracy of measuring the strength of the hydrogel particles.

[0033] Furthermore, the adjusting assembly includes an "L"-shaped adjusting plate, the side wall of the adjusting plate is fixedly connected to the inner wall of the box body, a plurality of limiting blocks are fixedly connected to both ends of the top of the adjusting plate, and a first threaded rod is rotatably connected between the limiting blocks at one end, and a second threaded rod is rotatably connected between the limiting blocks at the other end.

[0034] One end of the first threaded rod is provided with a first double-headed motor, the output shaft of the first double-headed motor is coaxially and fixedly connected to the first threaded rod, one end of the second threaded rod is provided with a second double-headed motor, the output shaft of the second double-headed motor is coaxially and fixedly connected to the second threaded rod, and the side walls of the first double-headed motor and the second double-headed motor are both fixedly connected to the inner wall of the box body.

[0035] At one end of the first double-headed motor and the second double-headed motor away from the first threaded rod and the second threaded rod, there is a blowing assembly for drying the hydrogel particles.

[0036] A first nut seat is threadedly connected to the first threaded rod, and a second nut seat is threadedly connected to the second threaded rod. One side of the first nut seat is fixedly connected to a sliding plate. A second opening is formed on the surface of the sliding plate. The support block is slidably engaged with the second opening. One side of the support block close to the second nut seat penetrates and is slidably engaged with a sliding rod. The end of the sliding rod away from the support block is fixedly connected to the second nut seat.

[0037] Beneficial effects: Through the threaded connection of the first threaded rod and the second threaded rod and the movement of the first nut seat and the second nut seat, the precise adjustment of the position of the support block is achieved. This adjustment method has high precision and stability, ensuring the accuracy of the measurement results.

[0038] The driving of the adjustment assembly depends on the first double-headed motor and the second double-headed motor, both of which can be precisely controlled by the controller. Therefore, the entire adjustment process can be automated and intelligentized, greatly improving the detection efficiency and accuracy.

[0039] Furthermore, the blowing assembly includes a fan. The output shafts of the first double-headed motor away from the first threaded rod and the second double-headed motor away from the second threaded rod are both fixedly connected to the fan. A plurality of air ducts are fixedly connected to the inner wall of the box body. One end of each air duct is adjacent to the fan, and the other end of each air duct is adjacent to the bearing plate.

[0040] Beneficial effects: The fan is fixedly connected to the output shafts of the first double-headed motor and the second double-headed motor. When the motors operate, the fan will rotate accordingly, generating an air flow. The air ducts guide the air flow generated by the fan to the vicinity of the bearing plate, further helping to dry the bearing plate and the hydrogel particles thereon, reducing the influence of the residual moisture on the hydrogel particles on the determination of the strength of the hydrogel particles.

[0041] Furthermore, the top of the bearing plate is covered with an anti-slip pad for increasing the friction between the bearing plate and the hydrogel particles.

[0042] Beneficial effects: The introduction of the anti-slip pad significantly increases the friction between the top of the bearing plate and the hydrogel particles, making the hydrogel particles more stable during the measurement process and not prone to sliding or displacement.

[0043] Furthermore, a plurality of heat dissipation holes are formed on the side wall of the box body.

[0044] Beneficial effects: During the operation of the drive motor, the first double-headed motor, and the second double-headed motor, a large amount of heat is generated. The heat dissipation holes allow the air inside the box to exchange with the outside air, effectively dissipating the heat generated inside the box. The continuous rotation of the fan also promotes the air inside the box to enter the outside air through the heat dissipation holes, improving the heat dissipation efficiency inside the box.

[0045] Furthermore, a method for measuring the strength of hydrogel particles includes the following steps:

[0046] Step 1: Select several hydrogel particles to be measured for strength, and choose hydrogel particles without bubbles and with uniform hydrogel.

[0047] Step 2: Irradiate the selected hydrogel particles with light, and judge the standard refractive index of the light passing through the hydrogel particles.

[0048] Step 3: Transport the hydrogel particles through the feeding port, funnel, and transport pipeline onto the bearing plate.

[0049] Step 4: Irradiate the hydrogel particles with a beam emitter, detect the refraction position of the light with a photoelectric detector, and judge the refractive index of the hydrogel particles through a controller.

[0050] Step 5: Compare the refractive index with the standard refractive index. If the refractive index is different from the standard refractive index, it is judged that the hydrogel particles have one or more of the conditions of having bubbles and non-uniform hydrogel.

[0051] Step 6: Start the drive motor and use the arc-shaped plate to fix the hydrogel particles on the bearing plate.

[0052] Step 7: Start the first double-headed motor and the second double-headed motor, adjust the position of the electric pressing plate, and squeeze the hydrogel particles to measure the strength of the hydrogel particles.

[0053] Beneficial effects: By selecting hydrogel particles without bubbles and with uniform hydrogel as the reference object for the light refractive index, the accuracy and reliability of the measurement results of the light refractive index of the remaining hydrogel particles can be ensured. At the same time, by using the method of light irradiation and refractive index judgment, hydrogel particles that meet the standards can be further screened out, reducing the measurement error caused by material problems.

[0054] Through the precise control of the beam emitter and the photoelectric detector, the accurate measurement of the refractive index of hydrogel particles can be achieved. At the same time, by adjusting the position and force of the electric pressing plate, the conditions of the extrusion measurement can be precisely controlled to ensure the accuracy and consistency of the measurement results.

[0055] During the measurement process, if it is found that the refractive index of the hydrogel particles is different from the standard refractive index, it can be immediately determined that there are problems such as air bubbles or uneven hydrogel in the particles, and then they can be removed in time. This helps to ensure the accuracy of the final measurement of hydrogel particles.

[0056] Additional aspects and advantages of the present invention will be given in part in the following description, become apparent in part from the following description, or be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0063] The following is a more detailed description through specific embodiments:

[0064] Example 1:

[0065] As shown in the attached Figures 1-4As shown: A device for measuring the strength of hydrogel particles, including a box body 1. There is a feeding port at the top of the box body 1. A controller 2 is fixedly connected to the surface of the box body 1 by screws. Inside the box body 1, there is a fixing component for restricting the position of the hydrogel particles. Between the fixing component and the feeding port, there is an arranging component for arranging the hydrogel particles. Above the fixing component, there is a pressurizing component for measuring the strength of the hydrogel particles. A beam emitter 26 for emitting detection light is fixedly connected to the inner wall of the box body 1 by screws. The beam emitter 26 is located between the fixing component and the pressurizing component. Inside the fixing component, there is a photodetector 27 for receiving the detection light.

[0066] The controller 2 is used to input the standard refractive index when the hydrogel particles have no bubbles and the hydrogel is uniform.

[0067] The controller 2 is used to judge the diameter of the hydrogel particles based on the position of the light emitted by the beam emitter 26 and the light received by the photodetector 27.

[0068] The controller 2 is used to judge the refractive index of the hydrogel particles located on the fixing component based on the detection light emitted by the beam emitter 26 and the position where the photodetector 27 receives the detection light, and make a judgment with the standard refractive index. When the refractive index is the same as the standard refractive index, the controller 2 will determine that the hydrogel particles meet the measurement requirements. When the refractive index is different from the standard refractive index, the controller 2 will judge that the hydrogel does not meet the measurement requirements.

[0069] As Figure 2 shown, the arranging component includes a funnel 28. The top of the funnel 28 is fixedly connected and communicated with the feeding port by bolts. The bottom of the funnel 28 is fixedly connected with a transportation pipeline 29 by bolts. An electromagnetic valve is fixedly connected and communicated inside the transportation pipeline 29 by screws. The controller 2 is used to control the opening and closing of the electromagnetic valve. The bottom end of the transportation pipeline 29 corresponds to the fixing component.

[0070] As Figure 4 shown, the fixing component includes a telescopic plate 20. A number of first grooves are opened at the bottom of the telescopic plate 20. A first gear 22 is rotatably connected to the bottom of the telescopic plate 20. A number of second grooves 24 are opened on the first gear 22. Telescopic rods 21 are slidably fitted in the first grooves. The bottom ends of the telescopic rods 21 are slidably fitted with the adjacent second grooves 24.

[0071] One end of each telescopic rod 21 away from the telescopic plate 20 is fixedly connected with a sliding block 17 by bolts. The sliding blocks 17 are all slidably fitted with the inner bottom wall of the box body 1.

[0072] The top of each sliding block 17 is fixedly connected with an electric push rod 23 by bolts. The controller 2 is used to control the start and stop of the electric push rod 23. The output shafts of the electric push rods 23 are all fixedly connected with arc-shaped plates 19 by bolts.

[0073] The inner side wall of the box body 1 is fixedly connected with a bearing plate 18 through bolts. The bearing plate 18 is located between the arc-shaped plate 19 and the telescopic plate 20. A number of first openings are formed in the bearing plate 18, and the electric push rods 23 all penetrate through the first openings and are in sliding fit with the first openings.

[0074] The first gear 22 meshes with the second gear 16. The second gear 16 is rotationally fitted with the telescopic plate 20, and a power assembly for driving the second gear 16 to rotate is provided at the bottom of the second gear 16.

[0075] As Figure 4 shown, the power assembly includes a driving motor 15. The output shaft of the driving motor 15 is coaxially fixedly connected with the second gear 16 through bolts. The driving motor 15 is fixedly connected to the inner bottom wall of the box body 1 through bolts. The controller 2 is used to control the start and stop of the driving motor 15.

[0076] As Figure 3 shown, the pressurizing assembly includes an electric extrusion plate 9. A pressure sensor is fixedly connected to the bottom of the electric extrusion plate 9 through screws. The controller 2 is used to receive the pressure data monitored by the pressure sensor; the controller 2 is used to control the lifting of the electric extrusion plate 9. When it is necessary to measure the strength of the hydrogel particles, the controller 2 controls the electric extrusion plate 9 to descend. When it is necessary to stop measuring the strength of the hydrogel particles, the controller 2 controls the electric extrusion plate 9 to ascend. A support block 10 is fixedly connected to the top of the electric extrusion plate 9 through bolts, and an adjusting assembly for adjusting the position of the support block 10 is provided at the top of the support block 10.

[0077] The adjusting assembly includes an "L"-shaped adjusting plate 13. The side wall of the adjusting plate 13 is fixedly connected to the inner wall of the box body 1 through bolts. A number of limiting blocks 11 are fixedly connected to both ends of the top of the adjusting plate 13 through bolts. A first threaded rod 12 is rotatably connected between the limiting blocks 11 at one end, and a second threaded rod 5 is rotatably connected between the limiting blocks 11 at the other end.

[0078] One end of the first threaded rod 12 is provided with a first double-headed motor 3. The output shaft of the first double-headed motor 3 is coaxially fixedly connected with the first threaded rod 12 through bolts. One end of the second threaded rod 5 is provided with a second double-headed motor 7. The output shaft of the second double-headed motor 7 is coaxially fixedly connected with the second threaded rod 5 through bolts. The side walls of the first double-headed motor 3 and the second double-headed motor 7 are both fixedly connected to the inner wall of the box body 1 through bolts.

[0079] Blowing assemblies for drying the hydrogel particles are provided at the ends of the first double-headed motor 3 and the second double-headed motor 7 away from the first threaded rod 12 and the second threaded rod 5.

[0080] A first nut seat 30 is threadedly connected to the first threaded rod 12, and a second nut seat 6 is threadedly connected to the second threaded rod 5. One side of the first nut seat 30 is fixedly connected to a sliding plate 31 by bolts. A second opening 14 is formed on the surface of the sliding plate 31. The support block 10 is slidably engaged with the second opening 14. A sliding rod 8 penetrates and is slidably engaged with the support block 10 near the second nut seat 6. The end of the sliding rod 8 away from the support block 10 is fixedly connected to the second nut seat 6 by bolts.

[0081] The specific implementation process is as follows: First, the staff needs to select hydrogel particles without bubbles and with uniform hydrogel from the hydrogel particles, and use the beam emitter 26 and the photodetector 27 to calculate the standard refractive index of the hydrogel particles without bubbles and with uniform hydrogel according to the deflection degree of the light passing through the hydrogel particles.

[0082] Then, the staff can pour the hydrogel particles to be measured for strength into the funnel 28 through the feeding port, and control the opening and closing of the solenoid valve through the controller 2, so that the hydrogel particles can enter the bearing plate 18 in sequence through the conveying pipeline 29.

[0083] When the hydrogel particles enter the bearing plate 18, the beam emitter 26 is turned on, and the beam emitter 26, the photodetector 27 and the controller 2 are used to judge the diameter of the hydrogel particles entering the bearing plate 18.

[0084] When the hydrogel particles fall onto the bearing plate 18, the controller 2 obtains the diameter data of the hydrogel particles. At this time, the controller 2 can start the driving motor 15 by control, Figure 4 For example, the driving motor 15 drives the second gear 16 to rotate. Since the second gear 16 is engaged with the first gear 22, when the second gear 16 rotates, it will drive the first gear 22 to rotate. When the first gear 22 rotates, it will drive the telescopic rod 21 to slide in the second groove 24. When the telescopic rod 21 slides in the second groove 24, it will also slide in the first groove in the telescopic plate 20. Thus, the telescopic rod 21 can achieve elongation and contraction. According to the diameter size of the hydrogel particles obtained by the controller 2, the telescopic rod 21 can be accurately extended to the diameter size of the hydrogel particles.

[0085] Combined with Figure 2 As shown, when the telescopic rod 21 extends, the sliding block 17 will slide along the inner bottom wall of the box body 1. While the telescopic rod 21 extends, the controller 2 will control the telescopic movement of the electric push rod 23. According to the diameter data of the hydrogel particles obtained by the controller 2, the height of the arc-shaped plate 19 is adjusted by the electric push rod 23, so that the arc-shaped plate 19 can better wrap and fix the hydrogel particles. The stability of the hydrogel particles during strength measurement is improved.

[0086] For Figure 2For example, after the hydrogel particles are fixed, the light can be emitted through the beam emitter 26, and then received by the photodetector 27. When the light emitted by the beam emitter 26 passes through the hydrogel particles, certain refraction will occur. The refractive index of the light can be calculated by the photodetector 27. The calculated refractive index of the light is compared with the standard refractive index tested at the beginning. If there is a deviation between the refractive index and the standard refractive index, it indicates that there are air bubbles in the hydrogel particles or the hydrogel is unevenly distributed. At this time, the staff needs to remove the hydrogel particles and select the hydrogel particles with the same refractive index as the standard refractive index for strength measurement.

[0087] By comparing the refractive index with the standard refractive index, the staff can easily select and remove the hydrogel particles with air bubbles or uneven gel distribution, thereby improving the accuracy of the strength measurement of the hydrogel particles.

[0088] Take Figure 3 as an example. When performing strength measurement, the controller 2 is started through the first double-headed motor 3. At this time, the first nut seat 30 will move continuously to the right under the rotation of the first threaded rod 12. When the first nut seat 30 moves to the right, the sliding plate 31 will also move to the right with the first nut seat 30. By starting the second double-headed motor 7, the second nut seat 6 will move continuously forward under the rotation of the second threaded rod 5. When the second nut seat 6 moves forward, it will drive the sliding rod 8 to move forward continuously. The support block 10 is driven by the sliding rod 8 to slide forward in the second opening 14.

[0089] Through the adjustment in the front-back direction and the left-right direction, the electric pressing plate 9 can be aligned with the hydrogel particles. Then the controller 2 can start the electric pressing plate 9 to extend. The pressure sensor at the bottom of the electric pressing plate 9 monitors the pressure exerted by the electric pressing plate 9 on the hydrogel particles, so as to measure the strength of the hydrogel particles.

[0090] Embodiment 2:

[0091] As Figure 3 shown, the difference from the above embodiment is that the blowing assembly includes a fan 4. The output shafts of the first double-headed motor 3 away from the first threaded rod 12 and the second double-headed motor 7 away from the second threaded rod 5 are both fixedly connected to the fan 4 by bolts. A plurality of air ducts 25 are fixedly connected to the inner wall of the box body 1 by bolts. One end of each air duct 25 is adjacent to the fan 4, and the other end of each air duct 25 is adjacent to the carrier plate 18.

[0092] The specific implementation process is as follows: When the controller 2 controls the first double-headed motor 3 and the second double-headed motor 7 to adjust the position of the electric pressing plate 9, the fan 4 will rotate simultaneously. At this time, the wind generated by the fan 4 will be blown onto the bearing plate 18 through the air duct 25 to dry the hydrogel particles on the bearing plate 18. When there is too much moisture on the surface of the hydrogel particles, it will affect the measured strength of the hydrogel particles. Blowing dry the moisture on the surface of the hydrogel particles by the fan 4 is beneficial to improving the accuracy of the hydrogel strength measurement.

[0093] Example 3:

[0094] The difference from the above embodiment is that an anti-slip pad for increasing the friction with the hydrogel particles is covered on the top of the bearing plate 18. In this embodiment, the anti-slip pad is preferably a rubber pad.

[0095] The specific implementation process is as follows: The hydrogel particles are extremely easy to slide. By covering an anti-slip pad on the top of the bearing plate 18, the friction between the hydrogel particles and the bearing plate 18 can be significantly increased, reducing the sliding of the hydrogel particles, thereby improving the stability in the process of measuring the strength of the hydrogel particles.

[0096] Example 4:

[0097] The difference from the above embodiment is that a plurality of heat dissipation holes are opened on the side wall of the box body 1.

[0098] The specific implementation process is as follows: The first double-headed motor 3, the second double-headed motor 7 and the drive motor 15 will release heat during operation. When the heat cannot be released in the box body 1 and the temperature in the box body 1 is too high, it will affect the strength measurement of the hydrogel particles and is not conducive to the accuracy of the strength measurement. By opening heat dissipation holes on the side wall of the box body 1, the air circulation between the air inside the box body 1 and the air outside the box body 1 can be significantly improved, and the heat in the box body 1 can be effectively dissipated to the external environment.

[0099] Example 5:

[0100] As Figure 5 shown, a method for measuring the strength of hydrogel particles includes the following steps:

[0101] Step 1: Select a number of hydrogel particles to be measured for strength, and select hydrogel particles without bubbles and with uniform hydrogel.

[0102] Step 2: Irradiate the selected hydrogel particles with light, and judge the standard refractive index of the light passing through the hydrogel particles.

[0103] Step 3: Transport the hydrogel particles onto the bearing plate 18 through the feed port, the funnel 28 and the transport pipe 29.

[0104] Step 4: Irradiate the hydrogel particles with the light beam emitter 26, detect the refraction position of the light by the photodetector 27, and determine the refractive index of the hydrogel particles by the controller 2.

[0105] Step 5: Compare the refractive index with the standard refractive index. If the refractive index is different from the standard refractive index, it is determined that the hydrogel particles have one or more of the conditions of air bubbles and uneven hydrogel.

[0106] Step 6: Start the drive motor 15 and use the arc-shaped plate 19 to fix the hydrogel particles on the carrier plate 18.

[0107] Step 7: Start the first double-headed motor 3 and the second double-headed motor 7, adjust the position of the electric pressing plate 9, and squeeze the hydrogel particles to measure the strength of the hydrogel particles.

[0108] The specific implementation process is as follows: First, the staff needs to carefully select hydrogel particles with a flat appearance, no air bubbles, and uniform hydrogel distribution from the hydrogel particles to be tested.

[0109] Then, use the light beam emitter 26 and the photodetector 27 to conduct a preliminary light irradiation test on the selected hydrogel particles. By observing the refraction of the light passing through the hydrogel particles, the standard refractive index of the hydrogel particles is preliminarily determined.

[0110] Pour the selected hydrogel particles into the funnel 28 through the feed port. The bottom of the funnel 28 is connected to the transport pipe 29, and a solenoid valve is provided in the pipe to control the number of hydrogel particles. When the solenoid valve is opened, the hydrogel particles slide along the pipe onto the carrier plate 18.

[0111] Then, use the light beam emitter 26 to perform precise light irradiation on the hydrogel particles. After the light emitted by the light beam emitter 26 passes through the hydrogel particles, refraction occurs. The photodetector 27 is located at the end of the light refraction path, used to receive the refracted light and convert it into an electrical signal. The controller 2 receives these electrical signals and calculates the refractive index of the hydrogel particles.

[0112] Subsequently, compare the refractive index calculated by the controller 2 with the standard refractive index. If there is a difference between the refractive index and the standard refractive index, it is determined that the hydrogel particles have problems such as air bubbles or uneven hydrogel distribution and need to be removed.

[0113] For the hydrogel particles that meet the refractive index requirements, start the drive motor 15. Drive the arc-shaped plate 19 to move and fix the hydrogel particles on the carrier plate 18.

[0114] Then start the first double-headed motor 3 and the second double-headed motor 7. When the electric extrusion plate 9 slowly descends and touches the hydrogel particles, start applying pressure. The pressure sensor monitors and records the applied pressure value in real time. By analyzing the change curve of the pressure value over time through the controller 2, the strength of the hydrogel particles can be evaluated.

[0115] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom still fall within the protection scope of the present invention.
