Description

Technical Field

[0001] The present invention relates to the technical field of bursting strength detection, and specifically provides a device and method for detecting the bursting strength of sanitary products. Background Art

[0002] Sanitary products usually include toilet paper, wet wipes, diapers, sanitary napkins, etc. It is necessary to detect the bursting strength of these products to ensure that they do not break easily during use. Different products may require different test standards and methods. At the same time, the functions of paper towels are constantly changing. From ordinary paper towels at the beginning to soft paper towels, and then disinfected paper towels and facial tissues have emerged after development. It is necessary to detect the breakage degree of different types of paper.

[0003] However, some existing detection devices cannot flatten the surface of the detection material during use, resulting in wrinkles during bursting strength detection. As a result, the paper needs to be provided with greater pressure by the ejection mechanism when being broken, leading to a decrease in measurement accuracy. At the same time, during long-term use, the expandable rubber film inside the detection body gradually wears out as the working time increases. As a result, the rubber film may bulge and its elasticity may decrease during subsequent use, affecting the detection efficiency and accuracy of the device.

[0004] In view of the above problems, it is urgent to innovate and design on the original basis. Summary of the Invention

[0007] Preferably, the rotating assembly includes a test head which is rotatably installed in the inner cavity of a cylindrical sleeve, and a sliding groove is formed on the side of the cylindrical sleeve.

[0008] Preferably, the pushing assembly includes a rotating rod rotatably installed at the lower end of the test head through a rotating shaft, and a pressing block is rotatably installed at the lower end of the rotating rod.

[0009] Preferably, the rotating rods are arranged at equal angles below the test head, the rotating rods are symmetric about both sides of the pressing block, and the position of the pressing block corresponds to the position of the moving block.

[0010] Preferably, the rotating assembly includes a connecting rod, one end of the connecting rod is slidably arranged in a groove formed at the upper end of the test head, the other end is fixedly installed with a movable rod, and a spiral groove is formed on the surface of the movable rod.

[0011] Preferably, a ratchet wheel rotatably installed inside the detection body is sleeved at the lower end of the movable rod, a guide rod is fixedly installed on the inner wall of the ratchet wheel, the front end of the guide rod is arranged in the spiral groove of the movable rod through a pulley, a rotating wheel I rotatably installed inside the detection body is sleeved outside the ratchet wheel, and an elastic limiting block is arranged on the rotating wheel I for clamping with the ratchet wheel.

[0012] Preferably, the transmission assembly includes a fixed rod rotatably installed on the detection body and a transmission belt. Two rotating wheels II with the same specifications are fixedly installed on the fixed rod. The rotating wheel II below the fixed rod is connected with an adjusting disc and the rotating wheel I through the transmission belt. The rotating wheel II above the fixed rod is connected with a rotating disc through the transmission belt, and the rotating disc and the adjusting disc have the same diameter.

[0013] Preferably, the clamping member includes a clamping block I, a clamping block II and a movable column. The clamping block I is fixedly installed at the upper end of the movable column. The front end of the clamping block II is arc-shaped, and the clamping block II is slidably installed on the movable column. The movable column is limited and slid in the sliding groove, and a spring is arranged between the clamping block I and the clamping block II.

[0014] Preferably, inclined surfaces from bottom to top are arranged on both sides of the sliding groove, abutting blocks are fixedly installed on both sides of the clamping block, and the abutting blocks abut against the inclined ends of the inclined surfaces.

[0015] Preferably, the method includes the following steps: S1: Place the object to be detected on the detection body, push the test head downward through the electric push rod to fix the material. When the test head moves downward, the material to be detected is leveled through the pushing assembly to reduce wrinkles on the surface of the material; S2: As the test head descends, the pushing component contacts the moving block and drives the moving block to move along the sliding groove, causing the moving block to drive the clamping member to move backward and clamp and stretch the elastic rubber installed on the detection body.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, through the provided pushing component, during the downward pressing of the test head, the pressing block first comes into contact with the test material through the rotating rods arranged at equal angles below. As the test head moves downward, the rotating rods deflect, and the deflected rotating rods level the material placed on the detection body through the pressing block, reducing the wrinkles generated on the surface of the material, thereby increasing the overall measurement accuracy of the device. 2. In this invention, by providing a moving block corresponding to the position of the pressing block, the pressing block can drive the moving block to displace during movement, causing the moving block to drive the fixedly connected clamping member to move towards the inner side of the sliding groove. As a result, the clamping member clamps the rubber sleeve through the inclined surface of the sliding groove and stretches the rubber sleeve, enabling the rubber sleeve to always maintain a highly elastic state and ensuring the detection efficiency of the device. Furthermore, after the detection is completed and the detection head moves upward, the detection head drives the movable rod to move upward synchronously through the connecting rod. The movable rod drives the first rotating wheel to rotate through the ratchet structure. At the same time, the first rotating wheel is connected to the adjusting disk and the second rotating wheel through the transmission belt. Through the cooperation of the transmission component, the second rotating wheel, and the connecting rod, the rotating disk and the adjusting disk can be synchronously adjusted, enabling the rotating rod and the moving block to always maintain a corresponding position. Meanwhile, when adjusting the clamping position of the clamping member on the rubber member, the rubber member is subjected to the same tensile force everywhere, preventing the rubber member from deforming during long-term use and improving the overall service life of the rubber member.

[0022] As an embodiment of the present invention, the pushing component includes a rotating rod 501 rotatably installed at the lower end of the test head 5 through a rotating shaft, and a pressing block 502 is rotatably installed at the lower end of the rotating rod 501.

[0024] The test head 5 is pushed downward by the electric push rod 4, and as the test head 5 continuously moves downward, the rotating rod 501 is driven to deflect. The deflected rotating rod 501 flattens the material placed on the surface of the machine body through the pressing block 502, preventing the material from bulging and wrinkling during detection; As an embodiment of the present invention, the rotating component includes a connecting rod 12. One end of the connecting rod 12 is slidably arranged in a groove opened at the upper end of the test head 5, and the other end is fixedly installed with a movable rod 13.

[0025] As an embodiment of the present invention, a ratchet wheel 14 rotatably installed inside the detection machine body 1 is sleeved at the lower end of the movable rod 13. A guide rod 15 is fixedly installed on the inner wall of the ratchet wheel 14. The front end of the guide rod 15 is arranged in the spiral groove of the movable rod 13 through a pulley.

The rotating wheel two 19 above the fixed rod 18 is connected to the rotating disc 3 through the transmission belt. The rotating disc 3 and the adjusting disc 7 have the same diameter.

[0027] As an embodiment of the present invention, the clamping member 10 includes a clamping block one 1001, a clamping block two 1002 and a movable column 1003. The clamping block one 1001 is fixedly installed at the upper end of the movable column 1003. The front end of the clamping block two 1002 is arc-shaped, and the clamping block two 1002 is slidably installed on the movable column 1003. The movable column 1003 is slidably limited in the sliding groove 9. A spring is arranged between the clamping block one 1001 and the clamping block two 1002.

[0028] As an embodiment of the present invention, inclined surfaces from bottom to top are arranged on both sides of the sliding groove 9. Contact blocks 1004 are fixedly installed on both sides of the clamping block two 1002, and the contact blocks 1004 are in contact with the inclined ends of the inclined surfaces.

[0029] As an implementation manner of the present invention, the method includes the following steps: S1: Place the object to be detected on the detection body 1, and use the electric push rod 4 to push the test head 5 downward to fix the material. When the test head 5 moves downward, the material to be detected is leveled by the pushing component to reduce wrinkles on the material surface; S2: As the test head 5 descends, the pushing component contacts the moving block 11 and drives the moving block 11 to move along the sliding groove, so that the moving block 11 drives the clamping member 10 to move backward and clamp and stretch the elastic rubber installed on the detection body 1; S3: Then start the bottom ejection mechanism. The ejection mechanism continuously moves upward to break the detected object by squeezing the elastic rubber, and data is recorded. When the detection is completed, as the test head 5 resets, the movable rod 13 makes the turntable 3 and the adjustment disk 7 perform synchronous angle adjustment through the cooperation of the ratchet 14, the guide rod 15, the first rotating wheel 16 and the transmission component.

[0030] As the pressing block 502 continuously moves, the pressing block 502 contacts the moving block 11, and then pushes the moving block 11 to move along the slot on the turntable 8. At the same time, the moving block 11 drives the clamping member 10 to move inward along the sliding groove 9, so that the second clamping block 1002 can move upward through the inclined surface, and cooperate with the first clamping block 1001 to clamp and stretch the rubber sheet, so that the rubber sheet can maintain high elasticity, facilitating the device to perform detection. The ratchet 14 drives the first rotating wheel 16 to rotate, and the first rotating wheel 16 drives the adjustment disk 7 to rotate through the transmission structure.

[0031] Working principle: Place the material to be detected on the detection body 1, and then start the electric push rod 4. The electric push rod 4 pushes the test head 5 to move downward along the cylindrical sleeve 6. During the downward movement of the test head 5, the pressing block 502 is pushed by the rotating rod 501 to level the material on the surface of the detection body 1, preventing wrinkles and protrusions on the material surface, which may cause a greater thrust during subsequent damage detection and lead to a large error in the measurement accuracy; As the pressing block 502 continuously moves, the pressing block 502 contacts the moving block 11. The pressing block 502 drives the moving block 11 to move along the sliding groove 9. The moving block 11 drives the clamping member 10 to move synchronously through the fixed connection with the first clamping block 1001. At the same time, the second clamping block 1002 on the lower side of the clamping member 10 moves on the inclined surfaces on both sides of the sliding groove 9 through the abutting blocks 1004 on both sides, so that the second clamping block 1002 moves backward and upward at the same time, so that the clamping member 10 can fixedly clamp the rubber part, and stretch the rubber mold by the backward movement of the clamping member 10, so that the rubber mold remains in a elastic state before each ejection, making the measurement data more accurate; After the measurement is completed, the test head 5 moves upward under the action of the electric push rod 4. The test head 5 drives the movable rod 13 on the left side of the machine body to move upward synchronously through the connecting rod 12. During the upward movement of the movable rod 13, the ratchet 14 rotates through the movement of the guide rod 15 inside the spiral groove, and then drives the first rotating wheel 16 to rotate through the ratchet 14 and the limit block 17. The rotating first rotating wheel 16 drives the adjusting disc 7 to deflect through transmission. The deflected adjusting disc 7 drives the fixedly installed turntable 8 to deflect synchronously, thereby synchronously adjusting the position of the clamping member 10 on the adjusting disc 7, causing the position of the clamping member 10 for the next clamping to deflect. At the same time, the adjusting disc 7 deflects synchronously with the turntable 3 through the transmission belt, the second rotating wheel 19 and the fixed rod 18, and then drives the pushing assembly at the lower end of the test head 5 and the clamping member 10 to always correspond in position through the turntable 3.
