Description

Technical Field

[0001] The invention relates to the technical field of hydrogel particle strength determination, and in particular to a hydrogel particle strength determination device and method. Background Art

[0002] Hydrogel particles are a material composed of hydrophilic polymers that can regulate the adsorption and transfer properties of the material. They can be made of natural or synthetic polymers and given various shapes and sizes through a variety of preparation techniques, such as batch emulsion, microfluidic emulsion, photolithography, electrohydraulic spray, and mechanical fragmentation. Hydrogel particles are widely used in cell culture, tissue engineering, and drug and protein delivery due to their high water content, properties similar to natural extracellular matrix, and diverse properties.

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

[0004] The existing hydrogel particle strength measuring device currently requires staff to inspect the hydrogel specimens before testing, and remove specimens with obvious defects and uniformity that do not meet the test standards. This process is time-consuming and laborious, and is prone to misjudgment due to eye fatigue of the staff, thereby affecting the accuracy of subsequent test results. Therefore, it is necessary to propose a hydrogel particle strength measuring device and method that can automatically detect hydrogel particles. Summary of the invention

[0005] To solve the above problems, the present invention provides a hydrogel particle strength measurement device and method, which uses a light beam emitter, a photodetector and a controller to determine the refractive index of the hydrogel particles, and thereby determine whether the hydrogel particles have defects or the hydrogel uniformity is insufficient.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a device and method for measuring the strength of hydrogel particles, comprising a box body, a feed inlet is opened on the top of the box body, a controller is fixedly connected to the surface of the box body, a fixing component for limiting the position of hydrogel particles is provided in the box body, an arranging component for arranging hydrogel particles is provided between the fixing component and the feed inlet, a pressurizing component for measuring the strength of 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, the light beam emitter is located between the fixing component and the pressurizing component, and a photoelectric detector for receiving detection light is provided in the fixing component.

[0007] The controller is used to input a 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 through the positions of the light emitted by the light beam emitter and the light received by the photoelectric detector.

[0009] The controller is used to determine the refractive index of the hydrogel particles located on the fixed component through the detection light emitted by the light beam emitter and the position where the photoelectric detector receives the detection light, and to 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 scheme is as follows: the light beam emitter is responsible for emitting light, which passes through the hydrogel particles, and the photodetector is placed at the bottom of the hydrogel particles to capture and record the state of the light after passing through the hydrogel particles.

[0011] The refractive index is a measure of a material's ability to refract light. Different materials have different refractive indices. When light passes from air into a hydrogel particle, the direction of the light changes. This phenomenon is called refraction. The degree of refraction depends on the refractive indices of the two media. The controller can calculate the angle of refraction when the light passes through the hydrogel particle by comparing the position difference between the light emitted by the beam emitter and the light received by the photodetector.

[0012] When there are bubbles, impurities or insufficient uniformity inside the hydrogel particles, their refractive index will change. The controller pre-inputs a standard refractive index when there are no bubbles in the hydrogel particles 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 means that the uniformity and quality of the hydrogel particles are good and meet the measurement requirements. If the two are very different, it means that the hydrogel particles may have defects or insufficient uniformity and do not meet the measurement requirements.

[0014] The above scheme has the following beneficial effects: 1. The present invention realizes automatic detection of hydrogel particles through a beam emitter, a photodetector and a controller. This greatly reduces the time and labor cost of manual inspection, improves the detection efficiency, and makes the entire detection process more efficient and faster. Automatic detection also brings about a significant improvement in detection accuracy. Since the entire detection process is completed by a high-precision beam emitter, a photodetector and a controller, it is possible to reduce 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 promptly discover potential quality problems, and ensures the stability and reliability of the product.

[0015] 2. The refractive index and diameter of hydrogel particles are measured with high accuracy using optical principles. By comparing the measured refractive index with the standard refractive index, it is helpful to accurately evaluate the quality and uniformity of hydrogel particles. And this high-precision detection method helps to discover potential quality problems in a timely manner and provide a reliable basis for subsequent strength determination.

[0016] 3. The present invention uses optical detection, which does not cause physical damage to the hydrogel particles and achieves non-destructive detection. This helps to preserve the integrity of the hydrogel particles for subsequent strength determination or other tests.

[0017] Furthermore, the arrangement component includes a funnel, the top of the funnel is fixedly connected to the feed port, the bottom of the funnel is fixedly connected to a transport pipe, the transport pipe is fixedly connected to a solenoid valve, the controller is used to control the opening and closing of the solenoid valve, and the end of the transport pipe away from the funnel corresponds to the fixed component.

[0018] Beneficial effects: The design of the funnel enables the hydrogel particles to enter the transport pipeline in a concentrated and orderly manner, avoiding confusion and accumulation of particles during the feeding process.

[0019] Guided by the transport pipeline, the hydrogel particles can be neatly arranged in the transport pipeline. The opening and closing of the solenoid valve is controlled by the controller to transport the hydrogel particles to the fixed component, which provides convenience for subsequent strength measurement.

[0020] Furthermore, the fixing component includes a telescopic plate, a plurality of first grooves are opened 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 opened on the first gear, telescopic rods are slidably fitted in the first grooves, and the bottom ends of the telescopic rods are slidably fitted in the second grooves adjacent to them.

[0021] One end of the telescopic rod away from the telescopic plate is fixedly connected with a sliding block, and the sliding block is slidably matched with the bottom wall of the box body.

[0022] The top of the sliding block is fixedly connected with an electric push rod, the controller is used to control the start and close of the electric push rod, and the output shaft of the electric push rod is fixedly connected with an arc plate.

[0023] A bearing plate is fixedly connected to the inner wall of the box body. The bearing plate is located between the arc plate and the telescopic plate. A plurality of first openings are opened on the bearing plate. The electric push rods all pass through the first openings and are slidably matched with the first openings.

[0024] The first gear is meshed with the second gear, the second gear is rotationally matched with the telescopic plate, and a power component for driving the second gear to rotate is provided at the bottom of the second gear.

[0025] Beneficial effect: The controller can determine the diameter of the hydrogel particles and adjust the rotation angle of the power component and the extension of the electric push rod according to the diameter of the hydrogel particles, thereby realizing the movement and fixation of the arc plate and improving the accuracy and efficiency of fixation.

[0026] The sliding cooperation between the sliding block and the bottom wall of the box body, and the sliding cooperation between the arc-shaped plate and the first opening on the bearing plate ensure the stability of the fixing component during the movement.

[0027] Furthermore, the power assembly includes a drive motor, the output shaft of the drive motor is coaxially fixedly connected to the second gear, the drive motor is fixedly connected to the bottom wall of the box body, and the controller is used to control the start and stop of the drive motor.

[0028] Beneficial effect: The output shaft of the driving motor is coaxially fixedly connected with the second gear, ensuring the accuracy of transmission. When the driving motor is started, the second gear will rotate at a predetermined speed and direction, thereby driving the movement of the first gear and the telescopic rod, thereby achieving accurate fixation of the hydrogel particles.

[0029] Furthermore, the pressurizing component 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 and lowering of the electric extrusion plate. When the strength of the hydrogel particles needs to be measured, the controller controls the electric extrusion plate to descend, and when the strength measurement of the hydrogel particles needs to be stopped, 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 adjustment component for adjusting the position of the support block is provided on the top of the support block.

[0030] Beneficial effect: The hydrogel particles are squeezed by an electric squeezing plate, and the pressure on the hydrogel particles is determined by a pressure sensor, thereby determining the strength of the hydrogel particles.

[0031] The electric extrusion plate can accurately control the height through the controller, thereby improving the accuracy of hydrogel particle strength measurement.

[0032] Furthermore, the adjustment component includes an "L"-shaped adjustment plate, the side wall of the adjustment plate is fixedly connected to the inner wall of the box body, and a plurality of limit blocks are fixedly connected to the two ends of the top of the adjustment plate, wherein a first threaded rod is rotatably connected between the limit blocks at one end, and a second threaded rod is rotatably connected between the limit blocks at the other end.

[0033] A first double-headed motor is provided at one end of the first threaded rod, and the output shaft of the first double-headed motor is coaxially fixedly connected to the first threaded rod; a second double-headed motor is provided at one end of the second threaded rod, and the output shaft of the second double-headed motor is coaxially fixedly connected to the second threaded rod; 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.

[0034] The first double-headed motor and the second double-headed motor are both provided with a blowing assembly for drying the hydrogel particles at one end away from the first threaded rod and the second threaded rod.

[0035] The first threaded rod is threadedly connected with a first nut seat, and the second threaded rod is threadedly connected with a second nut seat. A sliding plate is fixedly connected to one side of the first nut seat, and a second opening is opened on the surface of the sliding plate. The support block is slidably matched with the second opening. A sliding rod passes through and slidably matches one side of the support block close to the second nut seat, and the end of the sliding rod away from the support block is fixedly connected to the second nut seat.

[0036] Beneficial effect: 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 position of the support block is accurately adjusted. This adjustment method has high precision and stability, ensuring the accuracy of the measurement results.

[0037] The drive of the adjustment component 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 intelligent, greatly improving the detection efficiency and accuracy.

[0038] Furthermore, the blowing assembly includes a fan, the output shaft of the first double-headed motor away from one end of the first threaded rod and the output shaft of the second double-headed motor away from one end of the second threaded rod are both fixedly connected to the fan, and a plurality of air ducts are fixedly connected to the inner wall of the box, one end of the air ducts is adjacent to the fan, and the other end of the air ducts is adjacent to the supporting plate.

[0039] Beneficial effect: The fan is fixedly connected to the output shafts of the first double-headed motor and the second double-headed motor. When the motor is running, the fan will rotate accordingly to generate airflow. The air duct guides the airflow generated by the fan to the vicinity of the carrier plate, further helping the carrier plate and the hydrogel particles thereon to dry, and reducing the influence of residual moisture on the hydrogel particles on the strength determination of the hydrogel particles.

[0040] Furthermore, the top of the carrying plate is covered with an anti-skid pad for increasing the friction between the carrying plate and the hydrogel particles.

[0041] Beneficial effect: The introduction of the anti-slip pad significantly increases the friction between the top of the carrier plate and the hydrogel particles, making the hydrogel particles more stable during the measurement process and less likely to slide or shift.

[0042] Furthermore, a plurality of heat dissipation holes are provided on the side wall of the box body.

[0043] Beneficial effect: A large amount of heat is generated during the operation of the drive motor, the first double-headed motor and the second double-headed motor. The heat dissipation holes allow the air inside the box to be exchanged with the outside air, effectively dissipating the heat generated inside the box. The continuous rotation of the fan will also promote the air inside the box to enter the outside air through the heat dissipation holes, thereby improving the heat dissipation efficiency inside the box.

[0044] Further, a method for determining the strength of hydrogel particles comprises the following steps: Step 1: Select several hydrogel particles that need to be tested for strength, and select hydrogel particles that do not contain bubbles and have uniform hydrogel.

[0045] Step 2: Irradiate the selected hydrogel particles with light to determine the standard refractive index of the hydrogel particles after the light passes through.

[0046] Step 3: transport the hydrogel particles to the carrying plate through the feed port, the funnel and the transport pipe.

[0047] Step 4: Irradiate the hydrogel particles through the light beam emitter, detect the refraction position of the light through the photoelectric detector, and determine the refractive index of the hydrogel particles through the controller.

[0048] 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 bubbles and hydrogel inhomogeneity.

[0049] Step 6: Start the driving motor to fix the hydrogel particles on the supporting plate using the arc plate.

[0050] Step 7: Start the first double-headed motor and the second double-headed motor, adjust the position of the electric extrusion plate, and extrude the hydrogel particles to measure the strength of the hydrogel particles.

[0051] Beneficial effects: By selecting hydrogel particles without bubbles and with uniform hydrogel as reference objects for the light refractive index, the accuracy and reliability of the light refractive index measurement results of the remaining hydrogel particles can be ensured. At the same time, the method of light irradiation and refractive index judgment can be used to further screen out hydrogel particles that meet the standards and reduce measurement errors caused by material problems.

[0052] Through the precise control of the beam emitter and the photodetector, the refractive index of the hydrogel particles can be accurately measured. At the same time, by adjusting the position and strength of the electric extrusion plate, the conditions of the extrusion measurement can be precisely controlled to ensure the accuracy and consistency of the measurement results.

[0053] During the measurement process, if the refractive index of the hydrogel particles is found to be different from the standard refractive index, it can be immediately determined that the particles have bubbles or uneven hydrogels, and thus they can be removed in time. This helps to ensure the accuracy of the final hydrogel particle measurement.

[0054] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The controller 2 is used to input a standard refractive index when there are no bubbles in the hydrogel particles and the hydrogel is uniform.

[0060] The controller 2 is used to determine the diameter of the hydrogel particles through the position of the light emitted by the light beam emitter 26 and the light received by the photodetector 27 .

[0061] The controller 2 is used to determine the refractive index of the hydrogel particles located on the fixed component through the detection light emitted by the light beam emitter 26 and the position where the detection light is received by the photodetector 27, and to compare it 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 determine that the hydrogel does not meet the measurement requirements.

[0062] like Figure 2 As shown, the arrangement component includes a funnel 28, the top of the funnel 28 is connected to the feed port by bolts, the bottom of the funnel 28 is connected to a transport pipe 29 by bolts, the inside of the transport pipe 29 is connected to a solenoid valve by screws, the controller 2 is used to control the opening and closing of the solenoid valve, and the bottom end of the transport pipe 29 corresponds to the fixed component.

[0063] like Figure 4 As shown, the fixing assembly includes a telescopic plate 20, a plurality of first grooves are formed at the bottom of the telescopic plate 20, a first gear 22 is rotatably connected to the bottom of the telescopic plate 20, a plurality of second grooves 24 are formed on the first gear 22, and telescopic rods 21 are slidably fitted in the first grooves, and the bottom ends of the telescopic rods 21 are slidably fitted in the second grooves 24 adjacent thereto.

[0064] One end of the telescopic rod 21 away from the telescopic plate 20 is fixedly connected to the sliding block 17 by bolts, and the sliding block 17 is slidably matched with the inner bottom wall of the box body 1.

[0065] The top of the sliding block 17 is fixedly connected to 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 shaft of the electric push rod 23 is fixedly connected to an arc plate 19 by bolts.

[0066] The inner wall of the box body 1 is fixedly connected with a bearing plate 18 by bolts. The bearing plate 18 is located between the arc plate 19 and the telescopic plate 20. The bearing plate 18 is provided with a plurality of first openings. The electric push rods 23 all pass through the first openings and slide in cooperation with the first openings.

[0067] The first gear 22 is meshed with the second gear 16 , and the second gear 16 is rotationally matched with the telescopic plate 20 . A power assembly for driving the second gear 16 to rotate is provided at the bottom of the second gear 16 .

[0068] like Figure 4 As shown, the power assembly includes a drive motor 15, the output shaft of the drive motor 15 is coaxially connected to the second gear 16 by bolts, the drive motor 15 is fixedly connected to the bottom wall of the box body 1 by bolts, and the controller 2 is used to control the start and stop of the drive motor 15.

[0069] like Figure 3 As shown, the pressurizing component includes an electric extrusion plate 9, and a pressure sensor is fixedly connected to the bottom of the electric extrusion plate 9 by 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 and lowering 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, and when it is necessary to stop measuring the strength of the hydrogel particles, the controller 2 controls the electric extrusion plate 9 to rise. The top of the electric extrusion plate 9 is fixedly connected to a support block 10 by bolts, and the top of the support block 10 is provided with an adjustment component for adjusting the position of the support block 10.

[0070] The adjustment assembly includes an "L"-shaped adjustment plate 13, the side wall of the adjustment plate 13 is fixedly connected to the inner wall of the box body 1 by bolts, and a plurality of limit blocks 11 are fixedly connected to the top ends of the adjustment plate 13 by bolts, wherein a first threaded rod 12 is rotatably connected between the limit blocks 11 at one end, and a second threaded rod 5 is rotatably connected between the limit blocks 11 at the other end.

[0071] A first double-headed motor 3 is provided at one end of the first threaded rod 12, and the output shaft of the first double-headed motor 3 is coaxially connected to the first threaded rod 12 by bolts. A second double-headed motor 7 is provided at one end of the second threaded rod 5, and the output shaft of the second double-headed motor 7 is coaxially connected to the second threaded rod 5 by 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 by bolts.

[0072] The first double-headed motor 3 and the second double-headed motor 7 are both provided with a blowing assembly for drying the hydrogel particles at one end away from the first threaded rod 12 and the second threaded rod 5 .

[0073] The first threaded rod 12 is threadedly connected with a first nut seat 30, the second threaded rod 5 is threadedly connected with a second nut seat 6, one side of the first nut seat 30 is fixedly connected with a sliding plate 31 by bolts, a second opening 14 is opened on the surface of the sliding plate 31, the support block 10 is slidably matched with the second opening 14, a sliding rod 8 passes through and slidably matches the side of the support block 10 close to the second nut seat 6, and the end of the sliding rod 8 away from the support block 10 is fixedly connected with the second nut seat 6 by bolts.

[0074] 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 light 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 degree of deflection of light after passing through the hydrogel particles.

[0075] The staff can then pour the hydrogel particles that need to be tested for strength into the funnel 28 through the feed port, and control the opening and closing of the solenoid valve through the controller 2, so that the hydrogel particles can enter the supporting plate 18 through the transport pipe 29 in sequence.

[0076] The light beam emitter 26 is turned on when the hydrogel particles enter the carrier plate 18 , and the diameter of the hydrogel particles entering the carrier plate 18 is determined by using the light beam emitter 26 , the photodetector 27 and the controller 2 .

[0077] When the hydrogel particles fall onto the carrier 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 to Figure 4 For example, the second gear 16 is driven to rotate by the driving motor 15. Since the second gear 16 is meshed with the first gear 22, the rotation of the second gear 16 will drive the first gear 22 to rotate. The rotation of the first gear 22 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 through the first groove in the telescopic plate 20. In this way, the telescopic rod 21 can be extended and contracted. According to the diameter of the hydrogel particles obtained by the controller 2, the telescopic rod 21 can be accurately extended to the diameter of the hydrogel particles.

[0078] Combination Figure 2 As shown, when the telescopic rod 21 is extended, the sliding block 17 will slide along the inner bottom wall of the box body 1. When the telescopic rod 21 is extended, the controller 2 will control the electric push rod 23 to extend and retract. According to the diameter data of the hydrogel particles obtained by the controller 2, the height of the arc plate 19 is adjusted by the electric push rod 23, so that the arc plate 19 can better wrap and fix the hydrogel particles. The stability of the hydrogel particles during strength measurement is improved.

[0079] by Figure 2For example, after the hydrogel particles are fixed, the light can continue to be emitted through the beam emitter 26, and then the light beam is received by the photodetector 27. The light emitted by the beam emitter 26 will undergo a certain refraction when passing through the hydrogel particles. The refractive index of the light can be calculated by the photodetector 27, and the calculated refractive index of the light can be 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 means that there are 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.

[0080] By comparing the refractive index with the standard refractive index, staff can easily pick out hydrogel particles with bubbles or uneven gel distribution and remove them, thereby improving the accuracy of hydrogel particle strength measurement.

[0081] by Figure 3 For example, when performing strength measurement, the controller 2 will be started by the first double-headed motor 3. At this time, the first nut seat 30 will continue to move 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. The second double-headed motor 7 will be started. At this time, the second nut seat 6 will continue to move 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, and the sliding rod 8 will drive the support block 10 to slide forward in the second opening 14.

[0082] By adjusting the front-to-back and left-to-right directions, the electric extrusion plate 9 can be aligned with the hydrogel particles. Then the controller 2 can start the extension of the electric extrusion plate 9, and monitor the pressure applied by the electric extrusion plate 9 to the hydrogel particles through the pressure sensor at the bottom of the electric extrusion plate 9, so as to measure the strength of the hydrogel particles.

[0083] Embodiment 2:

[0084] like Figure 3 As shown, the difference from the above embodiment is that the blowing assembly includes a fan 4, the output shaft of the first double-headed motor 3 away from the end of the first threaded rod 12 and the output shaft of the second double-headed motor 7 away from the end of the second threaded rod 5 are both fixedly connected to the fan 4 by bolts, and a plurality of air ducts 25 are fixedly connected to the inner wall of the box body 1 by bolts, one end of the air ducts 25 is adjacent to the fan 4, and the other end of the air ducts 25 is adjacent to the supporting plate 18.

[0085] 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 extrusion plate 9, the fan 4 will rotate at the same time, and the wind generated by the fan 4 will be blown onto the carrier plate 18 through the air duct 25 to dry the hydrogel particles on the carrier plate 18. When there is too much moisture on the surface of the hydrogel particles, it will affect the strength of the hydrogel particles. Blowing the moisture on the surface of the hydrogel particles by the fan 4 is conducive to improving the accuracy of the hydrogel strength measurement.

[0086] Embodiment 3:

[0087] The difference from the above embodiment is that the top of the carrying plate 18 is covered with an anti-skid pad for increasing the friction between the carrying plate 18 and the hydrogel particles. In this embodiment, the anti-skid pad is preferably a rubber pad.

[0088] The specific implementation process is as follows: the hydrogel particles are very easy to slide. By covering the top of the supporting plate 18 with an anti-slip pad, the friction between the hydrogel particles and the supporting plate 18 can be significantly increased, reducing the sliding of the hydrogel particles, thereby improving the stability of the hydrogel particles during the strength measurement process.

[0089] Embodiment 4:

[0090] 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 .

[0091] The specific implementation process is as follows: the first double-headed motor 3, the second double-headed motor 7 and the driving motor 15 will release heat during operation. When the heat cannot be released in the box 1, the temperature in the box 1 is too high, which will affect the strength measurement of the hydrogel particles and is not conducive to the accuracy of the strength measurement.

[0092] Embodiment 5:

[0093] like Figure 5 As shown, a method for determining the strength of hydrogel particles comprises the following steps: Step 1: Select several hydrogel particles that need to be tested for strength, and select hydrogel particles that do not contain bubbles and have uniform hydrogel.

[0094] Step 2: Irradiate the selected hydrogel particles with light to determine the standard refractive index of the hydrogel particles after the light passes through.

[0095] Step 3: transporting the hydrogel particles onto the carrying plate 18 through the feed port, the funnel 28 and the transport pipe 29 .

[0096] Step 4: The hydrogel particles are irradiated by the light beam emitter 26 , the refraction position of the light beam is detected by the photoelectric detector 27 , and the refractive index of the hydrogel particles is determined by the controller 2 .

[0097] 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 bubbles and hydrogel inhomogeneity.

[0098] Step 6: Start the driving motor 15 to fix the hydrogel particles on the supporting plate 18 using the arc plate 19 .

[0099] Step 7: Start the first double-headed motor 3 and the second double-headed motor 7, adjust the position of the electric squeezing plate 9, and squeeze the hydrogel particles to measure the strength of the hydrogel particles.

[0100] The specific implementation process is as follows: First, the staff needs to carefully select hydrogel particles with a smooth appearance, no bubbles, and uniform hydrogel distribution from the hydrogel particles to be tested.

[0101] Then, the selected hydrogel particles are subjected to a preliminary light irradiation test using the light beam emitter 26 and the photoelectric detector 27. By observing the refraction of light after passing through the hydrogel particles, the standard refractive index of the hydrogel particles is preliminarily determined.

[0102] The selected hydrogel particles are poured into the funnel 28 through the feed port. The bottom of the funnel 28 is connected to a transport pipe 29, and a solenoid valve is provided in the pipe to control the amount of the hydrogel particles. When the solenoid valve is opened, the hydrogel particles slide along the pipe onto the carrier plate 18.

[0103] Then, the hydrogel particles are precisely illuminated with light using a beam emitter 26. After the light emitted by the beam emitter 26 passes through the hydrogel particles, it is refracted. The photodetector 27 is located at the end of the light refraction path, and is 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.

[0104] Then, the refractive index calculated by the controller 2 is compared 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 bubbles or uneven hydrogel distribution and need to be removed.

[0105] For the hydrogel particles meeting the refractive index requirement, the driving motor 15 is started to drive the arc plate 19 to move and fix the hydrogel particles on the supporting plate 18 .

[0106] Then start the first double-headed motor 3 and the second double-headed motor 7. When the electric squeezing plate 9 slowly descends and contacts the hydrogel particles, pressure begins to be applied. The pressure sensor monitors and records the applied pressure value in real time, and the controller 2 analyzes the curve of the pressure value changing over time to evaluate the strength of the hydrogel particles.

[0107] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
