Description

Technical Field

[0001] This utility model belongs to the field of hygiene product manufacturing technology, and in particular relates to a stretch detection device for baby diapers. Background Technology

[0002] In the prior art, a search revealed a Chinese patent disclosure entitled "A Diaper Tension Testing Device" with publication number "CN221898950U". This patent mainly benefits from the ability to insert one end of a straight diaper between the first clamping block and the second clamping block by rotating the first clamping block on the threaded rod upwards. Then, the threaded rod is rotated downwards to clamp the diaper. The other end of the straight diaper is then clamped by operating the other side. Then, the cylinder is activated to perform a tension test. When testing underwear-type diapers, the semi-circular lock is rotated to the designated direction and fastened into the waistband of the diaper to fix both ends. Then, the cylinder is activated. This allows for the tension test of underwear-type diapers without the need to change equipment, thus increasing its practicality.

[0003] However, this device has a relatively simple structure. It uses manual rotation of the threaded rod to drive two clamping blocks to fix the two ends of the diaper. When a large number of diapers need to be tested, the staff needs to rotate the threaded rod frequently, which is time-consuming and laborious. At the same time, if the manual operation fails and the clamping blocks do not clamp the diaper tightly, the diaper may fly out and break free of the clamping under the pulling force, affecting the product testing.

By setting up a clamping mechanism, it realizes the use of two hydraulic cylinders to drive the connecting block to approach the clamping block, and the clamping block to clamp and fix the diaper through the hinged connection of the arc-shaped connecting strip. This solves the problem of the time-consuming and laborious method of manually rotating the threaded rod to drive the two clamping blocks to fix the two ends of the diaper.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 As shown, this utility model is a baby diaper stretch detection device, including a fixed base 1, on which a clamping mechanism 2 and a stretching mechanism 3 are provided;

[0028] The clamping mechanism 2 includes a clamping assembly, a connecting assembly, and a limiting assembly. The clamping assembly includes two housings 21 mounted on a fixed base 1. A hydraulic cylinder 22 is fixedly connected to the side of each housing 21 that is far apart from the other. Connecting blocks 23 are slidably connected to the inner walls of each housing 21. The side of each connecting block 23 that is far apart from the other is fixedly connected to the output end of the hydraulic cylinder 22. Two arc-shaped connecting strips 24 are hinged to the inner walls of each connecting block 23. Clamping blocks 25 are hinged to the ends of each arc-shaped connecting strip 24. The connecting assembly includes rubber pads 26 fixedly connected to the sides of several clamping blocks 25 that are close to each other. The two housings... Each of the two housings 21 has a placement groove 27 on its side that is close to each other. The inner walls of the two placement grooves 27 are hinged with hinge blocks 28. The sides of the hinge blocks 28 that are close to each other are fixedly connected to the sides of the clamping blocks 25 that are far from each other. The bottom surface of the lower housing 21 is fixedly connected to the top surface of the fixed base 1. The inner wall of the fixed base 1 is fixedly connected to the lower hydraulic cylinder 22. The limiting assembly includes two limiting grooves 29 that are both opened on the inner walls of the two housings 21. The inner walls of the limiting grooves 29 are slidably connected with limiting blocks 210. The sides of the limiting blocks 210 that are close to each other are fixedly connected to the outer walls of the two limiting blocks 210.

[0029] By setting up the clamping mechanism 2, the connecting block 23 is driven by two hydraulic cylinders 22 to approach the clamping block 25. The clamping block 25 is driven by the hinged connection of the arc-shaped connecting strip 24 to clamp and fix the diaper. No manual operation is required for fixing, which saves time and effort. At the same time, it ensures that the device can still apply clamping force to the diaper during the stretch test, avoiding the situation where the clamping force is insufficient during the stretching process, which may cause the diaper to fall off and affect the test.

[0030] The stretching mechanism 3 includes a drive assembly and a lifting assembly. The drive assembly includes a support column 31 fixedly connected to the top surface of the fixed base 1. The bottom surface of the fixed base 1 has several mounting holes 32. The front surface of the support column 31 has a lifting groove 33. The inner wall of the lifting groove 33 is slidably connected to a slider 34. The inner wall of the support column 31 is fixedly connected to a motor 35. The outer walls of the upper outer shell 21 and the hydraulic cylinder 22 are both fixedly connected to the inner wall of the slider 34. The lifting assembly includes a threaded rod 36 rotatably connected to the inner wall of the lifting groove 33. The outer wall of the threaded rod 36 is threadedly connected to the inner wall of the slider 34. The bottom end of the threaded rod 36 is fixedly connected to the output end of the motor 35.

[0031] By setting up the stretching mechanism 3, the slider 34 is driven to rise and fall by the motor 35. With the clamping mechanism 2, the slider 34 stretches one end of the diaper held in the upper outer shell 21. The stretching test is completed at the same time, and the operation is automated, making the device suitable for production line testing and further improving the practicality of the device.

[0032] A specific application of this embodiment is as follows: By setting the clamping mechanism 2, the personnel place the two ends of the diaper to be tested between the placement slots 27 of the two outer shells 21. At this time, the two hydraulic cylinders 22 are driven to move the two connecting blocks 23 closer to each other, and to move the two limiting blocks 210 on them to slide in the limiting slots 29. The limiting blocks 210 and the limiting slots 29 limit the sliding of the connecting blocks 23. The sliding of the connecting blocks 23 causes the ends of the two arc-shaped connecting strips 24 hinged to them to slide in an arc-shaped trajectory, causing the clamping blocks 25 on the ends of the arc-shaped connecting strips 24 to rotate around the hinge point in the placement slots 27 through the hinge block 28, so that the two clamping blocks 25 drive the rubber pad block 26 to contact the diaper, clamping and fixing the diaper. The rubber pad 26 is designed with a concave-convex contact surface to enhance the clamping and fixing effect of the clamping block 25. The two outer shells 21 are respectively set on the fixed base 1 and the slider 34, which facilitates the lower clamping block 25 to relatively fix and hold the diaper. The upper clamping block 25 works with the stretching mechanism 3 to stretch the diaper and complete the quality inspection process. It realizes that the connecting block 23 is driven by two hydraulic cylinders 22 to approach the clamping block 25. The clamping block 25 is driven by the hinge of the arc-shaped connecting strip 24 to clamp and fix the diaper. No manual operation is required for fixing. It saves time and effort and ensures that the device can still apply clamping force to the diaper during the stretching test. It avoids the situation where the clamping force is insufficient during the stretching process, which may cause the diaper to fall off and affect the test.

[0033] By setting up a stretching mechanism 3, which works in conjunction with the clamping mechanism 2 to clamp and fix both ends of the diaper, the drive motor 35 drives the threaded rod 36 to rotate. Since the slider 34 is threadedly connected to the threaded rod 36, the rotation of the threaded rod 36 causes the slider 34 to slide upward along the thread in the lifting groove 33, causing the slider 34 to lift the upper outer shell 21. This pulls the diaper end clamped in the upper clamping block 25 upward. When the slider 34 rises to a certain extent, if the diaper does not break or other unqualified phenomena occur, it indicates that the diaper quality meets the standard; otherwise, the quality does not meet the standard. Several support columns 31 are set up to provide fixed support for the slider 34 and the threaded rod 36, and several mounting holes 32 are set up to facilitate the fixed installation of the device at a specific detection position. This realizes the use of the motor 35 to drive the slider 34 to rise and fall, in conjunction with the clamping mechanism 2, to clamp the diaper end clamped in the upper outer shell 21, stretching the diaper end. This completes the stretching test while automating the operation, making the device suitable for production line testing and further improving its practicality.
