Description

Technical Field

[0001] This invention relates to the field of diaper manufacturing technology, specifically to a water absorption testing device for the production of 3D embossed diapers. Background Technology

[0002] The absorbency testing equipment for diaper production is a specialized instrument used to determine the absorbency performance indicators of diapers, such as absorption speed, absorbency, and water retention capacity, in order to ensure product quality.

[0003] However, traditional absorbency testing equipment is difficult to adapt to diapers of different widths in terms of positioning and clamping. It is also prone to damage or displacement of diapers during testing due to excessive or insufficient clamping force, which affects the accuracy of the test results. Secondly, the testing methods are relatively simple, and can only perform simple static tests, which cannot reflect the absorbency performance of diapers in real-world usage scenarios, making it difficult to meet the strict requirements of actual production for product quality testing. Summary of the Invention

[0004] The purpose of this invention is to provide an absorbency testing device for the production of 3D embossed diapers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an absorbency testing device for the production of 3D embossed diapers, comprising a base, a pair of uprights symmetrically arranged on both sides of the base, a slippage detection component and a clamping component arranged on the base, and a compression backflow detection component arranged between the two uprights.

[0006] Using the above technical solution, the base serves as the foundation of the overall equipment, providing an installation position for the slippage detection component and the clamping component, while the columns on both sides of the base provide an installation foundation for the compression reverse osmosis detection component.

[0007] Preferably, the slippage detection assembly includes a connector one disposed on one side of the base, an inclined frame movably disposed on the connector one, and a telescopic cylinder one disposed on the side of the base away from the connector one via a hinge, the top of the telescopic rod of the telescopic cylinder one being connected to the inclined frame via a hinge.

[0008] Using the above technical solution, the connector in the slippage detection component provides an installation base for the tilt frame and allows the tilt frame to rotate at a certain angle around the connector. The telescopic cylinder can drive the tilt frame to rotate around the connector by extending and retracting the telescopic rod, so as to adjust the tilt angle and thus detect the slippage of the diaper.

[0009] Preferably, a rotating shaft is provided in the middle of the inclined frame via a bearing seat, a motor is provided on the side of the inclined frame away from the connector, the transmission end of the motor is connected to one end of the rotating shaft, a rotating seat is sleeved on the outer side of the rotating shaft, a U-shaped groove is provided on the rotating seat, and a drain pipe is provided on one side of the bottom of the rotating seat corresponding to the position of the U-shaped groove.

[0010] Using the above technical solution, the motor on one side of the tilting frame provides rotation power for the rotating shaft. When the rotating shaft rotates, it drives the rotating seat and the diaper it carries to rotate, simulating the user turning over and detecting whether the diaper will leak. The U-shaped groove on the rotating seat can collect the unabsorbed test liquid, and the drain pipe can discharge the collected test liquid.

[0011] Preferably, the clamping assembly includes a square groove formed on the side of the rotating seat away from the connector, a pair of support seats are provided in the square groove, a bidirectional lead screw is provided between the two support seats, a motor is provided on one side of the square groove, and the transmission end of the motor is connected to one end of the bidirectional lead screw.

[0012] Using the above technical solution, the square slot on the rotating seat in the clamping assembly provides an installation base for other components, the support seat one provides support for the bidirectional lead screw, ensuring the stability of the bidirectional lead screw during rotation, and the motor two provides rotational power for the bidirectional lead screw, converting the rotational motion of the bidirectional lead screw into the linear motion of the drive frame.

[0013] Preferably, a pair of drive frames are helically sleeved on the outer side of the bidirectional lead screw, and a pair of cover plates are provided on the square grooves on the outer side of the two drive frames. A guide rail is provided on the side of the rotating seat away from the square groove. The two drive frames are slidably mounted on the guide rail. A connecting piece 2 is provided at the bottom of each of the two drive frames, and a rubber positioning roller is sleeved on the two connecting pieces 2.

[0014] Using the above technical solution, the guide rail one provides guidance for the drive frame, ensuring the stability of the two drive frames when they move towards or away from each other. The cover plate can protect the internal components of the square groove from external environmental interference. When the drive frame moves, it drives the rubber positioning roller to move synchronously through the connector two. The rubber positioning roller can flatten the unfolded diaper and press its edges. The elasticity of the rubber can be adapted to diapers of different thicknesses to achieve stable positioning.

[0015] Preferably, the compression reverse osmosis detection assembly includes two pairs of support seats 2 respectively disposed at the top and bottom of the column, a rotating shaft 2 is disposed between each pair of support seats 2, a sprocket is sleeved on the outer side of the two rotating shafts 2, a chain is disposed between the two sprockets, a motor 3 is disposed on one side of the top of the column, one end of the top rotating shaft 2 is connected to the transmission end of the motor 3, a lifting frame is sleeved on the chain, a guide rail 2 is disposed on the column, and the side of the lifting frame away from the chain is slidably disposed on the guide rail 2.

[0016] Using the above technical solution, the support seat 2 in the reverse osmosis detection component provides support for the rotating shaft 2, ensuring the stability of the rotating shaft 2 when rotating. The motor 3 provides rotational power for the rotating shaft 2 at the top of the column. The sprocket on the rotating shaft 2 rotates synchronously. The sprocket drives the rotating shaft 2 and the sprocket at the bottom of the column to rotate through the chain. When the chain moves, it drives the lifting frame to rise and fall smoothly along the guide rail 2 on the other side of the column.

[0017] Preferably, a pressure cylinder is provided at the bottom of the lifting frame, a pressure sensor is provided on the pressure cylinder, and an end cap is connected to the bottom of the pressure cylinder by a thread. Several round holes are opened at the bottom of the end cap, and paper towels are placed inside the end cap.

[0018] Using the above technical solution, the lifting frame provides an installation base for the pressure cylinder and metering pump. The bottom of the pressure cylinder is connected to the end cap by a thread. The round hole on the end cap is used to collect the backflow liquid from the diaper by the paper towel inside. The pressure sensor on the pressure cylinder detects the clamping force in real time and feeds back the data to the controller.

[0019] Preferably, a metering pump is provided on one side of the lifting frame, and a liquid outlet pipe is provided at the bottom of the metering pump. A telescopic cylinder two is provided on one side of the base. A long support plate corresponding to the rotating seat is provided at the top of the telescopic rod of the telescopic cylinder two. A guide post is provided at the bottom of the long support plate. A guide sleeve is provided on the base at the position corresponding to the guide post. The telescopic cylinder one, motor one, motor two, motor three, metering pump and pressure sensor are connected to the controller.

[0020] Using the above technical solution, the metering pump delivers the test liquid to the diaper through the outlet pipe to simulate urine permeation. The telescopic cylinder on one side of the base drives the long support plate to rise and fall through the telescopic rod. After the long support plate rises, it can provide support for the rotating seat and tilting frame to ensure the stability during the compression and reverse osmosis test. The guide post at the bottom of the long support plate cooperates with the guide sleeve on the base to ensure the stability of the long support plate when it rises and falls.

[0021] Compared with the prior art, the beneficial effects of the present invention are: the absorbency testing equipment for the production of 3D embossed diapers: 1. By extending and retracting the telescopic rod of the telescopic cylinder in the slippage detection component, the tilt angle of the tilt frame and the rotating seat can be flexibly adjusted to detect the slippage of the diaper. Secondly, the motor drives the rotating shaft to rotate, which in turn drives the rotating seat and the diaper to rotate, simulating the user turning over and effectively detecting side leakage. In addition, the U-shaped groove on the rotating seat can collect unabsorbed test liquid, and the drain pipe can discharge it in time, making it convenient for staff to accurately judge the slippage performance of the diaper by observing the drainage and leakage status. 2. The motor in the clamping assembly drives the bidirectional lead screw to rotate, converting the rotational motion of the bidirectional lead screw into the linear motion of the drive frame. This causes the rubber positioning rollers on both sides to move in opposite directions along the guide rail, which can flatten and unfold the diaper and press and fix the edge of the diaper, thus adapting to diapers of different widths. In addition, the rubber material has good elasticity and can adapt to diapers of different thicknesses, improving the flexibility of the device. 3. The motor three in the compression backflow detection assembly provides rotational power to the rotating shaft two at the top of the column. The sprocket on the rotating shaft two rotates synchronously, and drives the rotating shaft two and sprocket at the bottom of the column to rotate via the chain. When the chain moves, it drives the lifting frame to rise and fall smoothly along the guide rail two on the other side of the column. When the lifting frame falls, it drives the pressure cylinder to press down synchronously. The pressure sensor on the pressure cylinder provides real-time feedback of the compression force data, which is convenient for the controller to adjust, thereby detecting the absorbency of the diaper when it is compressed. Secondly, the metering pump can deliver the test liquid quantitatively through the liquid outlet pipe to simulate urine permeation. The round hole on the end cap at the bottom of the pressure cylinder, in conjunction with the paper towel, can collect the backflow liquid from the diaper, thereby detecting the backflow performance of the diaper. In addition, the telescopic cylinder two drives the long support plate to rise and fall through the telescopic rod. When the long support plate rises and touches the rotating seat, it can provide stable support for the rotating seat and the tilting frame during detection. The cooperation between the guide column and the guide sleeve can ensure the stability of the long support plate when it rises and falls. Attached Figure Description

[0028] The compression reverse osmosis detection component 5 includes two pairs of support seats 51 respectively set at the top and bottom of the column 2. A rotating shaft 52 is set between each pair of support seats 51. A sprocket 53 is sleeved on the outside of the two rotating shafts 52. A chain 54 is set between the two sprockets 53. A motor 55 is set on one side of the top of the column 2. One end of the top rotating shaft 52 is connected to the transmission end of the motor 55. A lifting frame 56 is sleeved on the chain 54. A guide rail 57 is set on the column 2. The side of the lifting frame 56 away from the chain 54 is slidably set on the guide rail 57. The bottom of the lifting frame 56 is equipped with a pressure cylinder 58, and a pressure sensor is installed on the pressure cylinder 58. The bottom of the pressure cylinder 58 is connected to an end cap 59 by a thread. Several round holes 510 are opened at the bottom of the end cap 59, and paper towels 511 are placed inside the end cap 59. A metering pump 512 is installed on one side of the lifting frame 56. A liquid outlet pipe 513 is installed at the bottom of the metering pump 512. A telescopic cylinder 514 is installed on one side of the base 1. A long support plate 515 corresponding to the rotating seat 36 is installed at the top of the telescopic rod of the telescopic cylinder 514. A guide post 516 is installed at the bottom of the long support plate 515. A guide sleeve 517 is installed on the base 1 at the position corresponding to the guide post 516. The telescopic cylinder 33, motor 35, motor 44, motor 55, metering pump 512 and pressure sensor are connected to the controller. Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, firstly, the support base 51 in the reverse osmosis detection assembly 5 provides support for the rotating shaft 52, ensuring the stability of the rotating shaft 52 during rotation. The motor 55 provides rotational power for the rotating shaft 52 at the top of the column 2. The sprocket 53 on the rotating shaft 52 rotates synchronously. The sprocket 53 drives the rotating shaft 52 and the sprocket 53 at the bottom of the column 2 to rotate via the chain 54. When the chain 54 moves, it drives the lifting frame 56 to rise and fall smoothly along the guide rail 57 on the other side of the column 2. Secondly, the lifting frame 56 provides an installation base for the pressure cylinder 58 and the metering pump 512. The bottom of the pressure cylinder 58 is connected to the end cap 59 by a thread, and the round hole 5 on the end cap 59... 10. The paper towel 511 inside the diaper collects the backflow liquid from the diaper. The pressure sensor on the pressure cylinder 58 detects the clamping force in real time and feeds back the data to the controller. In addition, the metering pump 512 delivers the test liquid to the diaper through the liquid outlet pipe 513 to simulate urine permeation. The telescopic cylinder 514 on one side of the base 1 drives the long support plate 515 to rise and fall through the telescopic rod. After the long support plate 515 rises, it can provide support for the rotating seat 36 and the tilting frame 32 to ensure the stability during the backflow detection. The guide post 516 at the bottom of the long support plate 515 cooperates with the guide sleeve 517 on the base 1 to ensure the stability of the long support plate 515 when it rises and falls.

[0029] Working principle: When using this 3D embossed diaper production absorbency testing equipment, first place the 3D embossed diaper to be tested on the rotating seat 36, then connect the metering pump 512 to the test reagent storage tank through a pipeline. The test reagent contains a color developer, which can help the staff observe the absorbency performance of the diaper. Subsequently, the controller starts the second motor 44, which drives the bidirectional lead screw 43 to rotate, converting the rotational motion of the bidirectional lead screw 43 into the linear motion of the drive frame 45, so that the two drive frames 45 on both sides move away from each other along the first guide rail 47, and then drive the two rubber positioning rollers 49 to move synchronously through the second connector 48. The rubber positioning rollers 49 flatten and unfold the diaper on both sides and press the edge of the diaper tightly. The elasticity of the rubber material can adapt to diapers of different thicknesses, so as to achieve the positioning of the diaper.

[0030] After positioning, a pressure backflow test is performed. The controller activates the telescopic cylinder 514 on one side of the base 1. The telescopic rod of the telescopic cylinder 514 extends, driving the long support plate 515 to move upward until it contacts the rotating seat 36, thus providing stable support for the rotating seat 36 and the tilting frame 32. The cooperation between the guide post 516 and the guide sleeve 517 ensures the stability of the long support plate 515 during movement. Subsequently, the controller activates the motor 55, which drives the top rotating shaft 52 to rotate. The sprocket 53 on the rotating shaft 52 rotates synchronously, and drives the bottom rotating shaft 52 and sprocket 53 to rotate via the chain 54. When the chain 54 moves, it drives the lifting frame 56 to slide downward along the guide rail 57 on the other side of the column 2. The lifting frame 56 drives the bottom pressure cylinder 58 to move downward synchronously. When the end cap 59 at the bottom of the pressure cylinder 58 approaches the surface of the diaper... During operation, the pressure sensor on the pressure cylinder 58 detects pressure data in real time and feeds it back to the controller. The controller adjusts the operation of motor 3 55 according to the preset pressure value, so that the pressure cylinder 58 applies a stable pressing force to the diaper. Then, the controller controls the metering pump 512 on the lifting frame 56 to start. The metering pump 512 draws the test liquid and then delivers the test liquid to the surface of the diaper through the liquid outlet pipe 513 in a metered manner to simulate the urine permeation scenario. After the delivery is completed, the controller controls motor 3 55 to reverse, and the lifting frame 56 and pressure cylinder 58 rise. The staff can observe the absorption at the pressing point and loosen and remove the end cap 59 to observe the paper towel 511 inside the end cap 59. If there is backflow in the diaper, the backflowed liquid will permeate through several round holes 510 at the bottom of the end cap 59 to the paper towel 511 inside the end cap 59. The backflow performance of the diaper can be judged by observing the degree of wetting of the paper towel 511.

[0031] After the reverse osmosis test is completed, the controller controls the telescopic rod of the second telescopic cylinder 514 to retract, causing the long support plate 515 to move downwards and reset, releasing the support for the rotating seat 36 and the tilting frame 32. Then, the slippage and side leakage test phase begins, simulating actual usage scenarios such as a user turning over. The controller activates the first telescopic cylinder 33, whose telescopic rod extends, causing the tilting frame 32 to rotate around the connecting piece 31, thereby adjusting the tilt angle of the tilting frame 32 and the rotating seat 36. Simultaneously, the first motor 35 can be activated, driving the rotating shaft... Rotating shaft 34 drives rotating seat 36 and diaper to rotate together. During the test, if the diaper does not completely absorb the test liquid, the unabsorbed test liquid will slide out and enter the U-shaped groove 37 on rotating seat 36, and then be discharged through the drain pipe 38 at the bottom of rotating seat 36. The staff can judge its slippage and side leakage performance by observing the drainage of drain pipe 38 and the leakage state of diaper. After the test is completed, the controller moves the two rubber positioning rollers 49 away from each other, releases the clamp on the diaper, and the tested diaper can be taken out.
