Description

Technical Field

[0001] The present invention relates to the technical field of air permeability testing devices, and in particular to a tester for quantitatively testing the air permeability of pull-up pants products. Background Art

[0002] Pull-ups are a type of infant diaper. Methods for quantitatively testing the breathability of diapers mainly include the breathability tester method and the simple home version test. The breathability tester method is a professional testing method. The diaper sample is clamped on the breathability tester, and then some water is poured into the upper end of the tester. The air flow is adjusted to stabilize the air flow vertically through the sample at a constant flow rate. The amount of bubbles in the upper liquid is observed to evaluate the breathability of the diaper. If a large number of bubbles appear, it means that the diaper has good breathability. This method requires professional equipment and certain operating skills. It is usually used in laboratories or professional institutions to conduct quantitative evaluations of diaper breathability. It is a new material test, and the test and measurement comply with relevant standardization and certification and accreditation services.

[0003] When testing diapers using the existing technology of breathability tester, the diaper cover is usually pressed against the air outlet end of the tester. Because the material of diapers themselves is relatively soft, the different curvatures of diapers of different products during testing may have a certain impact on the test results. In addition, for conventional tests, a flat placement method is generally adopted, which has a shape difference from the curved structure formed after wearing. Whether this difference will affect the breathability also needs to be tested. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a tester for quantitatively testing the breathability of pull-up pants products to solve the problems raised in the above-mentioned background technology.

[0006] Furthermore, the clamping assembly also includes a bidirectional electric push rod, and the slide seat is slidably installed with a bidirectional electric push rod on both sides of the vertical upper clamping plate, and the two extended ends of the bidirectional electric push rod are fixedly connected to the upper clamping plate.

[0007] Furthermore, a telescopic plate is fixed to the side of the slide, and a second electric push rod is fixed to the extended end of the telescopic plate, the extended end of the second electric push rod is fixedly connected to the upper splint, and a third electric push rod is fixed at both ends of the upper splint, and the extended end of the third electric push rod is fixedly connected to the lower splint.

[0008] Furthermore, the base is fixed with vertical beams on both sides of the back of the top frame, and a sliding frame is fixed on the back of the top frame. The sliding frame is slidably sleeved on the vertical beams. The base is fixed with a first electric push rod on both sides of the front end of the top frame, and the extended end of the first electric push rod is fixedly connected to the top frame.

[0009] Furthermore, the drive assembly also includes a slide groove, the base is provided with a slide groove at the position of the second screw, and the second screw is rotatably installed inside the slide groove through a bearing, and the surface of the second screw is symmetrically threaded and sleeved on two sliders.

[0010] Furthermore, a blocking block is slidably connected inside the middle tube, and connecting rods are fixed on both sides of the blocking block. The connecting rods slide out of the middle tube and are fixed with vertical plates, and the vertical plates are fixedly connected to the sliders.

[0011] Furthermore, an air pump is fixed on the back of the base, and a delivery pipe is fixed to the outlet end of the air pump. The delivery pipe is fixedly connected to the top of the middle pipe located in the middle of the two diversion pipes.

[0012] Furthermore, the transmission assembly also includes a first bevel gear, the first screw passes through the top frame and is fixed with the first bevel gear, the bottom of the first bevel gear is meshed with a second bevel gear, and the bottom of the second bevel gear is fixed with a telescopic rod, and the extended end of the telescopic rod is rotatably connected to the top frame through a bearing seat.

[0014] Furthermore, the second air outlet pipe is arc-shaped, the first air outlet pipe and the second air outlet pipe have the same diameter, and pressure gauges are installed on the surfaces of the first air cylinder and the second air cylinder.

[0015] Beneficial effects of the present invention:

[0016] 1. In the present invention, the first and second air outlet pipes have the same height and diameter. The arc shape of the second air outlet pipe can be adjusted by lowering the clamping assembly and adjusting the distance between the clamps, so that the clamped diaper is tightly wrapped on the arc surface of the second air outlet pipe, simulating the wearing state of bending to test the breathability.

[0017] 2. In the present invention, when the first screw rotates, the first bevel gear rotates and engages with the second bevel gear, the second bevel gear drives the telescopic rod and the third bevel gear to rotate, and the third bevel gear engages with the fourth bevel gear, thereby driving the rotation of the second screw through the transmission belt.

[0018] 3. In the present invention, the second screw drives the slider to move along the slide groove, and the connecting rod drives the blocking block to move along the inside of the middle tube. The blocking block blocks the two branch pipe openings respectively, so that the gas sent into the delivery pipe can only enter the inside of the air cylinder on one side, and the air cylinder also happens to correspond vertically to the diaper.

[0019] 4. The present invention drives the top frame to slide up and down along the vertical beam through the first electric push rod, adjusts the position of the slide seat and the clamping assembly, and facilitates pressing the clamped diaper cover on the top of the outlet pipe. It is also convenient to lift it up and remove it to change the diaper.

[0020] 5. The present invention adjusts the distance between the two side splints through a bidirectional electric push rod, and can be adjusted according to the length of the diaper so that it maintains a flat and tight state when corresponding to the first air outlet pipe. When dealing with the second air outlet pipe, the position of the splint is adjusted according to the curvature of the diaper. At the same time, the telescopic plate will also expand or contract in accordance with the position of the splint to maintain the connection between the second electric push rod and the upper splint. The splint and the diaper can be moved downward through the second electric push rod. This structure can be used on the second air outlet pipe to make the two sides of the diaper tightly attached to the curved surface of the second air outlet pipe.

[0021] 6. Compared with the prior art, the present invention uses a slide and a clamping assembly to press the diaper onto the top of the first air outlet pipe in a flat form and onto the top of the second air outlet pipe in a curved form, respectively. The air permeability of the diaper in the flat state and the curved state simulated for wearing are tested respectively, which provides more accurate test results for the air permeability of the product itself and a more accurate comparison reference for different products.

When the device is used, The diaper is clamped inside the clamping assembly 3, and then the slide 21 and the clamping assembly 3 are driven by the driving assembly 4 to move along the top frame 2, and the positions of the first air cylinder 5 and the second air cylinder 6 are respectively corresponded. The diaper cover is pressed on the first air tube, and the gas flows out from the exhaust pipe 22 through the flat diaper. The air permeability in this state is measured, and then the diaper cover is pressed on the top of the second air outlet pipe 61, which becomes a curved shape. The air permeability in this state is measured, and the data is compared. At the same time, the two data of different products are compared.

[0032] In this embodiment, the clamping assembly 3 also includes a bidirectional electric push rod 31, and the slide 21 is vertically slidably installed on both sides of the upper splint 34 with a bidirectional electric push rod 31, and the two extended ends of the bidirectional electric push rod 31 are fixedly connected to the upper splint 34, and the side of the slide 21 is fixed with a telescopic plate 32, and the extended end of the telescopic plate 32 is fixed with a second electric push rod 33, and the extended end of the second electric push rod 33 is fixedly connected to the upper splint 34, and the two ends of the upper splint 34 are fixed with a third electric push rod 36, and the extended end of the third electric push rod 36 is fixedly connected to the lower splint 35, through the bidirectional electric push rod 31. By adjusting the distance between the two side splints toward the electric push rod 31, the length of the diaper can be adjusted so that it remains flat and tight when corresponding to the first air outlet pipe 51. When dealing with the second air outlet pipe 61, the position of the splint is adjusted according to the curvature of the diaper. At the same time, the telescopic plate 32 will also expand or contract in accordance with the position of the splint to maintain the connection between the second electric push rod 33 and the upper splint 34. The splint and the diaper can be moved downward through the second electric push rod 33. This structure can be used on the second air outlet pipe 61 to tightly attach the two sides of the diaper to the curved surface of the second air outlet pipe 61.

[0033] In this embodiment, the base 1 is located on both sides of the back side of the top frame 2 and is fixed with vertical beams 11, and a sliding frame 23 is fixed on the back side of the top frame 2, and the sliding frame 23 is slidably sleeved on the vertical beams 11, and the base 1 is located on both sides of the front end of the top frame 2 and is fixed with a first electric push rod 12, and the extended end of the first electric push rod 12 is fixedly connected to the top frame 2, and the first electric push rod 12 drives the top frame 2 to slide up and down along the vertical beams 11, adjusting the position of the slide 21 and the clamping assembly 3, so as to facilitate pressing the clamped diaper cover on the top of the outlet pipe, and also facilitate lifting it to remove it for changing the diaper.

[0034] In this embodiment, the driving assembly 4 also includes a slide groove 43. The base 1 is provided with a slide groove 43 at the position of the second screw 44, and the second screw 44 is rotatably installed inside the slide groove 43 through a bearing. The surface of the second screw 44 is symmetrically threaded on two sliders 45. The interior of the intermediate tube 83 is slidably connected to a block 84, and connecting rods 85 are fixed on both sides of the block 84. The connecting rod 85 slides out of the intermediate tube 83 and is fixed with a vertical plate 86, and the vertical plate 86 is fixedly connected to the slider 45. An air pump 8 is fixed to the back of the base 1, and a delivery pipe 81 is fixed to the outlet end of the air pump 8. The delivery pipe 81 is fixedly connected to the top of the intermediate pipe 83 located in the middle of the two branch pipes 82. The slider 45 is driven by the second screw 44 to move along the slide groove 43, and the connecting rod 85 drives the blocking block 84 to move along the inside of the intermediate pipe 83. The blocking block 84 blocks the pipe openings of the two branch pipes 82 respectively, so that the gas sent in by the delivery pipe 81 can only enter the inside of the air cylinder on one side, which also happens to correspond vertically to the diaper.

[0035] In this embodiment, the transmission assembly 9 also includes a first bevel gear 92, the first screw 42 passes through the top frame 2 and is fixed with the first bevel gear 92, the bottom of the first bevel gear 92 is meshed with a second bevel gear 93, and a telescopic rod 94 is fixed to the bottom of the second bevel gear 93, the extended end of the telescopic rod 94 is rotatably connected to the top frame 2 through a bearing seat, and a third bevel gear 95 is fixed to the bottom of the telescopic rod 94, the other end of the base 1 is located at the transmission belt 91 and is rotatably mounted with a shaft through a bearing seat, and a fourth bevel gear 96 is sleeved on the shaft at the other end of the transmission belt 91, and the fourth bevel gear 96 is meshed with the first bevel gear 96. The three bevel gears 95 are meshed and connected. When the first screw 42 rotates, the first bevel gear 92 rotates and meshes with the second bevel gear 93. The second bevel gear 93 drives the telescopic rod 94 and the third bevel gear 95 to rotate. The third bevel gear 95 meshes with the fourth bevel gear 96, thereby driving the rotation of the second screw 44 through the transmission belt 91. When the slide 21 moves and switches the diaper test position, the second screw 44 will change the gas delivery position by moving the position of the block 84. The driving ratio is that when the slide 21 is located at the top of the first air cylinder 5, the block 84 just completely blocks the shunt pipe 82 at one end of the second air cylinder 6.

[0036] In this embodiment, the second air outlet pipe 61 is arc-shaped, and the first air outlet pipe 51 and the second air outlet pipe 61 have the same diameter. A pressure gauge 7 is installed on the surface of the first air cylinder 5 and the second air cylinder 6. The first air outlet pipe 51 and the second air outlet pipe 61 have the same height and the same diameter. The arc shape of the second air outlet pipe 61 can be used to tightly wrap the clamped diaper on the arc surface of the second air outlet pipe 61 by lowering the clamping assembly 3 and adjusting the distance between the clamps, simulating the wearing state to test the air permeability. This structure does not necessarily accurately simulate the shape of the baby after wearing it. It only distinguishes the diaper from the flat state through this structure, and uses this shape as a reference. Other models of diapers are tested for air permeability in both flat and arc states respectively, which can more accurately determine the difference in air permeability. The pressure value inside the first air cylinder 5 and the second air cylinder 6 is reflected by the pressure gauge 7. This technical method can refer to the method of patent CN211627304U for testing and recording air permeability.

[0037] When using the device, the diaper is clamped inside the clamping assembly 3, and then the driving assembly 4 drives the slide 21 and the clamping assembly 3 to move along the top frame 2, and respectively corresponds to the positions of the first air cylinder 5 and the second air cylinder 6, and the diaper cover is pressed on the first air tube. The gas passes through the flat diaper and flows out from the exhaust pipe 22, and the air permeability in this state is measured. The diaper cover is then pressed on the top of the second air outlet pipe 61, and it becomes a curved shape. The air permeability in this state is measured, and the data is compared. At the same time, two data of different products are compared. The spacing between the two side splints is adjusted by the bidirectional electric push rod 31, and the length of the diaper can be adjusted so that it maintains a flat and tight state when corresponding to the first air outlet pipe 51. When dealing with the second air outlet pipe 61, the position of the splint is adjusted according to the curvature of the diaper. At the same time, the telescopic plate 32 will also cooperate with the position of the splint. The second electric push rod 33 is arranged to expand or contract, and the connection between the second electric push rod 33 and the upper splint 34 is maintained. The splint and the diaper can be moved downward by the second electric push rod 33. This structure can be used on the second air outlet pipe 61 to make the two sides of the diaper tightly attached to the arc surface of the second air outlet pipe 61. When the first screw 42 rotates, the first bevel gear 92 rotates and engages with the second bevel gear 93. The second bevel gear 93 drives the telescopic rod 94 and the third bevel gear 95 to rotate. The third bevel gear 95 engages with the fourth bevel gear 96, thereby driving the rotation of the second screw 44 through the transmission belt 91. When the slide 21 moves and switches the test position of the diaper, the second screw 44 will change the gas delivery position by moving the position of the block 84. The driving ratio is that when the slide 21 is at the top of the first air cylinder 5, the block 84 just completely blocks the shunt pipe 82 at one end of the second air cylinder 6.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
