Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a testing device for biodegradable materials in hygiene products. Background Technology

[0002] Hygiene products mainly include three categories: disposable hygiene products, cleaning products, and hygiene and health products. Specifically, they cover products such as menstrual hygiene products, excrement hygiene products, wet wipes, antibacterial agents, and bacteriostatic agents.

[0003] To meet environmental protection requirements, biodegradable materials are used in hygiene products such as sanitary napkins and overnight pads. Biodegradable sanitary napkins use natural or bio-based materials (such as bamboo fiber and polylactic acid) that can decompose naturally under certain conditions, reducing environmental pollution. When biodegradable materials are used in hygiene products, it is necessary to verify whether the materials have real degradation properties to help companies obtain third-party certification, enhance consumer trust, and expand market share.

[0004] Currently, the testing of biodegradable materials is generally divided into natural degradation and testing equipment (constant humidity and temperature chamber). Natural degradation requires placing the sample material in a specific environment for biodegradation testing, but this testing method takes a long time. Testing equipment can control and change the temperature and humidity in the environment, place the sample in a support plate inside the chamber, and the support plate can be adjusted in height as needed. By simulating environmental testing and ensuring storage stability, it can simulate the impact of different extreme environments on the performance of biodegradable materials, test the decomposition rate of the material under high temperature and high humidity, and the degree of embrittlement under low temperature and dry conditions, thereby evaluating its weather resistance and reliability in actual use.

[0005] Although the testing equipment can place materials in the support plate and test biodegradable materials by simulating specific environments, the current testing equipment requires the support plate to be pulled out of the box and the height of the four support blocks in the box to be adjusted and fixed before the support plate is placed on the four support blocks for support. The height adjustment method of the support plate is relatively complicated and it is difficult to improve the convenience of adjusting the height of the support plate. Utility Model Content

[0006] The purpose of this invention is to address the deficiencies and shortcomings of existing technologies by providing a testing device for biodegradable materials in hygiene products.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a testing device for biodegradable materials of hygiene products, comprising a testing body, a testing space formed on the testing body, a sealing door formed on the testing body for closing or opening the testing space, a support plate formed on the testing body within the testing space, and further comprising two connecting plates formed on the testing body within the testing space and symmetrically arranged on the left and right, a plurality of placement slots formed on the two connecting plates and equidistantly arranged longitudinally, and placement slots formed on the two connecting plates and connected to the testing space. The system includes a connecting slot, a slidable sliding plate on the connecting plate located within the slot, a push-off protrusion fixed at one end on the limiting plate and with a clearance fit between the other end and the slot, an arc surface on the other end of the push-off protrusion, an elastic element located between the limiting plate and the connecting plate within the slot, and arc slots on both ends of the support plate. The arc slots engage with the other end of the push-off protrusion. The height of the slot is greater than the height of the slot, and the height of the limiting plate is greater than the height of the slot. The slot and the slot together form a T-shaped groove.

[0008] A further improvement is that the elastic element is a compression spring.

[0009] A further improvement is that the elastic element is a nickel alloy spring, a copper alloy spring, or a stainless steel spring.

[0010] A further improvement is that the elastic element is a bellows or a rubber spring.

[0011] A further improvement is that the placement slot and the engagement slot are connected and opened on the front end face of the connecting plate, and the front end face of the connecting plate is provided with a detachable positioning element located within the placement slot and the engagement slot.

[0012] A further improvement is made: the positioning component includes T-shaped positioning blocks that respectively mate with the placement slot and the engagement slot; the front end of the connecting plate has a threaded opening that communicates with the placement slot; the T-shaped positioning block has a corresponding connection hole; a connecting bolt is provided in the corresponding connection hole on the T-shaped positioning block; the threaded part of the connecting bolt is threadedly connected to the threaded opening; and the threaded part of the connecting bolt is clearance-fitted with the corresponding connection hole.

[0013] A further improvement is that the T-shaped positioning block has a countersunk groove, and the head of the connecting bolt is located in the countersunk groove.

[0014] A further improvement is that the left and right ends of the support plate are provided with chamfered surfaces, which are located on the upper and lower sides of the arc groove.

[0015] A further improvement is that the two connecting plates are bolted to the testing machine body and located within the testing space.

[0016] The beneficial effects of this utility model after adopting the above technical solution are as follows: When it is necessary to adjust the lifting height of the support plate, simply apply force to lift or press the support plate upwards or downwards, causing the arc-shaped slots at both ends of the support plate to disengage from the initial position of the abutment protrusion. When the support plate is raised to the required height of the abutment protrusion, the side end face of the support plate is pressed against the arc-shaped surface of the other end face of the abutment protrusion, causing the abutment protrusion to be pressed and move laterally in the engaging slot towards the elastic element, thereby driving the limiting slide plate to compress the elastic element. The elastic deformation allows the elastic element to release its elastic potential energy when the position of the arc-shaped groove corresponds to the position of the engaging slot, pushing the limiting slide plate laterally towards the support plate. This causes the arc surface of the abutting protrusion to engage in the arc-shaped groove. Through the abutting of the left and right ends of the support plate, a vertical lifting resistance is provided to the support plate to fix its height. Compared with the traditional adjustment method, the adjustment method is simpler, eliminating the need to remove the support plate and adjust the height of the four support blocks, thus improving the convenience of adjusting the height of the support plate.

[0017] Further benefits: When it is necessary to remove the support plate from the detection space, the support plate can be pulled out horizontally towards the closed door through the cooperation of the arc groove and the arc surface.

[0018] Further benefits: When the T-shaped positioning block is removed from the placement slot and engagement slot at the front end of the connecting plate, it facilitates the removal, replacement, or repair of the limiting slide plate and the abutment protrusion. It also facilitates the installation of the limiting slide plate, the abutment protrusion, and the elastic element during assembly. When the T-shaped positioning block is installed in the placement slot and engagement slot at the front end of the connecting plate, the T-shaped positioning block can restrict the limiting slide plate and the abutment protrusion within the placement slot and engagement slot, preventing the limiting slide plate and the abutment protrusion from coming off the front end of the connecting plate.

[0019] Further benefits: The chamfered surface design allows the support plate to push the abutment to slide laterally when it moves up and down and contacts the other end of the abutment, so that the arc grooves on the left and right ends of the support plate can engage with the arc surface of the abutment.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0024] See Figures 1 to 6As shown, the technical solution adopted in this specific embodiment is: a testing device for biodegradable materials of hygiene products, including a testing body 1, a testing space 2 opened on the testing body 1, a sealing door 3 set on the testing body 1 for closing or opening the testing space 2, a support plate 4 set on the testing body 1 and located in the testing space 2, and further including two connecting plates 5 set on the testing body 1 and located in the testing space 2 and symmetrically arranged on the left and right, a plurality of placement slots 6 respectively opened on the two connecting plates 5 and arranged longitudinally at equal intervals, and a locking mechanism respectively opened on the two connecting plates 5 and connected to each placement slot 6 and the testing space 2. The structure includes: a groove 7; a limiting slide plate 8 slidably mounted on the connecting plate 5 within the placement groove 6; a stop protrusion 9 fixed at one end on the limiting slide plate 8 and with a clearance fit to the engaging groove 7 at the other end; an arc surface 10 on the other end face of the stop protrusion 9; an elastic element 12 located between the limiting slide plate 8 and the connecting plate 5 within the placement groove 6; and arc grooves 11 formed on the left and right end faces of the support plate 4, which engage with the other end face of the stop protrusion 9. The height of the placement groove 6 is greater than the height of the engaging groove 7, and the height of the limiting slide plate 8 is greater than the height of the engaging groove 7. The placement groove 6 and the engaging groove 7 form a T-shaped groove. The clearance between the stop protrusion 9 and the engaging groove 7 is 0.05-0.2mm, ensuring that it can only slide along the length of the engaging groove 7. The limiting slide plate 8 has a clearance fit with the inner wall of the placement slot 6 on both sides, with a clearance range of 0.1-0.5mm, ensuring that the limiting slide plate 8 can only slide horizontally. The placement slot 6, engaging slot 7, limiting slide plate 8, and abutting protrusion 9 are all provided in the same number. The number of elastic elements 12 is set according to the required spring force. Figure 6 As shown, the placement slot 6 and the engagement slot 7 have the same opening length, which is greater than the length of the limiting slide plate 8 and the abutting protrusion 9, so that the T-shaped positioning block 13 can be installed in the placement slot 6 and the engagement slot 7.

[0025] The elastic element 12 is a compression spring. When the elastic element 12 is selected as a compression spring, one end of the compression spring is installed in the placement slot 6 and then fixed to the inner wall of the placement slot 6 by welding or bonding, while the other end abuts against the side end face of the limiting slide plate 8.

[0026] The elastic element 12 is a nickel alloy spring, a copper alloy spring, or a stainless steel spring.

[0027] The elastic element 12 is either a corrugated tube or a rubber spring. The corrugated tube can be a PVC double-wall corrugated tube. The corrugated tube is first fixed to the side end face of the limiting slide plate 8 by adhesive bonding, with its other end abutting against the inner wall of the placement slot 6. The rubber spring can be fixed to the inner wall of the placement slot 6 by adhesive bonding, with its other end abutting against the side end face of the limiting slide plate 8.

[0028] The placement slot 6 and the engagement slot 7 are connected and opened on the front end face of the connecting plate 5. The front end face of the connecting plate 5 is provided with a detachable positioning component within the placement slot 6 and the engagement slot 7.

[0029] The positioning component includes a T-shaped positioning block 13 that is clearance-fitted with the placement slot 6 and the engagement slot 7 respectively. The front end of the connecting plate 5 has a threaded hole 14, which is connected to the placement slot 6. The T-shaped positioning block 13 has a corresponding connection hole 15. A connecting bolt 16 is provided on the T-shaped positioning block 13 in the corresponding connection hole 15. The threaded part of the connecting bolt 16 is threadedly connected to the threaded hole 14, and the threaded part of the connecting bolt 16 is clearance-fitted with the corresponding connection hole 15.

[0030] The T-shaped positioning block 13 has a countersunk groove 17, and the head of the connecting bolt 16 is located within the countersunk groove 17. The countersunk groove 17 is used to hide the head of the connecting bolt 16 when it fixes the T-shaped positioning block 13 to the front end of the connecting block. When it is necessary to remove the support plate 4 from between the two abutting protrusions 9, the removal process of the support plate 4 is not affected. When the elastic element 12 is not subjected to external force, one end of the elastic element 12 abuts against the side end face of the limiting slide plate 8. The depth of the countersunk groove 17 is greater than the height of the head of the connecting bolt 16, ensuring that the bolt head does not protrude from the surface of the T-shaped positioning block 13. The fitting clearance between the T-shaped positioning block 13 and the slot 6 and the engaging slot 7 is 0.1-0.3mm.

[0031] The support plate 4 has chamfered surfaces 18 at both ends, located on the upper and lower sides of the arc-shaped groove 11. The chamfered surfaces 18 form an angle of 30°-45° with the horizontal plane, serving to guide the lateral sliding of the abutment protrusion 9. The two connecting plates 5 are bolted to the testing body 1 and located within the testing space 2. During assembly, the elastic element 12 is first inserted into the engaging slot 7 at the front end of the connecting plate 5. The elastic element 12 is fixed in the engaging slot 7 by adhesive, ultrasonic welding, or brazing. Then, the limiting slide plate 8 and the abutting protrusion 9 are pushed into the engaging slot 7 and the placement slot 6 at the front end of the connecting plate 5, respectively, until the limiting slide plate 8 and the abutting protrusion 9 can no longer move inward. Next, the T-shaped positioning block 13 is placed into the engaging slot 7 and the placement slot 6 from the front end of the connecting plate 5, so that the T-shaped positioning block 13 is close to one side of the limiting slide plate 8 and the abutting protrusion 9. At this point, the corresponding mating hole 15 and the threaded opening 14 are aligned. The connecting bolt 16 is then inserted from the corresponding... Insert the connecting plate 16 into the hole 15 until the threaded part of the connecting bolt 16 is threaded into the threaded opening 14. After the two connecting plates 5 are initially assembled, install the two connecting plates 5 symmetrically on the left and right sides of the testing space 2 with bolts. Pick up the support plate 4 and align the arc grooves 11 at both ends of it with one end face of the abutment protrusion 9. Push the support plate 4 into the testing space 2 until the support plate 4 is completely installed in the testing space 2. When it is necessary to replace or repair the connecting plate 5 and its internal parts, pull the support plate 4 out from between the abutment protrusions 9, and then remove the connecting plate 5 from the testing body 1 with bolts. Replace the parts as needed. The connecting plate 5 and bolts are made of nylon, stainless steel, or resin materials.

[0032] The working principle of this utility model is as follows: When it is necessary to adjust the lifting height of the support plate 4, simply apply force to lift or press the support plate 4 upwards or downwards, causing the arc-shaped grooves 11 at both ends of the support plate 4 to disengage from the initial position of the abutment protrusion 9. When the support plate 4 is raised or lowered to the position of the abutment protrusion 9 at the required height, the side end face of the support plate 4 is pressed against the arc-shaped surface 10 of the other end face of the abutment protrusion 9, causing the abutment protrusion 9 to be pressed and moved laterally in the engagement slot 7 towards the elastic element 12, thereby driving the limiting slide plate 8 to compress the elastic element 12 and produce elastic deformation. When the position of the arc groove 11 corresponds to the position of the engagement slot 7, the elastic element 12 releases elastic potential energy to push the limiting slide plate 8 laterally towards the support plate 4, thereby causing the arc surface 10 of the abutting protrusion 9 to engage in the arc groove 11. Through the abutting of the left and right ends of the support plate 4, a vertical lifting resistance is provided to the support plate 4 to fix the height of the support plate 4. Compared with the traditional adjustment method, the adjustment method is simpler. There is no need to take out the support plate 4 and adjust the height of the four support blocks, which can improve the convenience of adjusting the height of the support plate 4. When it is necessary to remove the support plate 4 from the detection space 2, the support plate 4 can be pulled out horizontally towards the closed door 3 through the cooperation of the arc groove 11 and the arc surface 10. When the T-shaped positioning block 13 is removed from the placement slot 6 and engagement slot 7 at the front end of the connecting plate 5, it is convenient to remove and replace or repair the limiting slide plate 8 and the abutting protrusion 9. It is also convenient to install the limiting slide plate 8, the abutting protrusion 9 and the elastic element 12 during assembly. When the T-shaped positioning block 13 is installed in the placement slot 6 and engagement slot 7 at the front end of the connecting plate 5, the T-shaped positioning block 13 can restrict the limiting slide plate 8 and the abutting protrusion 9 in the placement slot 6 and engagement slot 7, preventing the limiting slide plate 8 and the abutting protrusion 9 from coming off the front end of the connecting plate 5. The chamfered surface 18 is designed so that when the support plate 4 moves up and down and contacts the other end of the abutment protrusion 9, the support plate 4 can push the abutment protrusion 9 to slide laterally through the chamfered surface 18, so that the arc grooves 11 at the left and right ends of the support plate 4 can engage with the arc surface 10 of the abutment protrusion 9.
