Description

Technical Field

[0001] This invention relates to the field of fabric testing technology, specifically a new material textile cleaning pad air permeability testing device. Background Technology

[0002] With the rapid development of the cleaning tool industry, new-generation textile cleaning pads (such as high-end mop pads, scouring pads, and disposable cleaning wipes) have widely adopted new materials such as composite fibers, microfibers, nanomaterials, and functional polymers. The breathability of these products directly determines their cleaning efficiency, user experience, and hygiene. Excellent breathability ensures rapid air and liquid flow during cleaning, allowing the cleaning pad to adhere closely to the surface, reducing resistance, improving the absorption efficiency of dirt and moisture, and accelerating the drying process after use, fundamentally inhibiting the growth of bacteria and mold.

[0003] Currently, although there are standard instruments in the industry for testing the air permeability of such porous textile materials, there are significant applicability issues when applying them to products with special structures like floor mats.

[0004] The direct testing method using a standard air permeability meter involves clamping the mop mat sample directly onto the designated test head of the meter. The instrument generates a fixed air pressure difference on one side of the sample, measuring the airflow rate through the sample over a certain time, or the pressure difference generated at a fixed flow rate. However, the surface of the mop mat is covered with dense fibers or loops, making it uneven and elastic. The flat pressure ring of the standard instrument cannot effectively compress and isolate these fibers, resulting in severe lateral air leakage at the clamping edges. Most of the air leaks from the edges of the clamping device rather than permeating the mop mat's base fabric, causing severely distorted test data that completely fails to reflect true air permeability, rendering the measurement results virtually worthless.

[0005] To address the air leakage problem, some testing personnel attempt to manually create clamps with larger, softer sealing rings, or apply sealants such as petroleum jelly to the sample testing area. However, manual sealing is time-consuming and labor-intensive, making it difficult to meet the needs of industrial-scale batch testing. While soft sealing rings can improve the seal, they are filled with fluff and cannot completely eliminate micro-leakage, nor can they simulate the compressed state of the mop pad in actual use.

[0006] Therefore, it is necessary to provide a new material textile cleaning pad breathability testing device to solve the problems mentioned in the background art. Summary of the Invention

[0007] To achieve the above objectives, the present invention provides the following technical solution: a novel material textile cleaning mat air permeability testing device, comprising a base, a support plate fixed on the base, two connecting shafts fixed to the base mounted above the support plate, a connecting plate below the connecting shafts, an outer cylinder fixed in the connecting plate, an inner cylinder inside the outer cylinder, a lifting tube slidingly penetrating the outer cylinder fixed at the upper end of the inner cylinder, a through hole concentric with the outer cylinder in the center of the support plate, a cover plate below the support plate capable of sealing the through hole, and a support telescopic cylinder connected to the cover plate.

[0008] Furthermore, the lower edge of the inner cylinder is serrated, and a drive motor is connected to the upper end of the lifting pipe.

[0009] Furthermore, an extension shaft is slidably provided at the lower end of the connecting shaft, and the lower end of the extension shaft is fixed to the connecting plate. A fixing plate is fixed above the outer cylinder, and the fixing plate is fixed to the extension shaft.

[0010] Furthermore, the outer wall of the outer cylinder is hinged with a first shift fork.

[0011] Furthermore, a sliding shaft is slidably provided at the lower end of the extension shaft, the lower end of the sliding shaft is fixed on the pressure ring, and a support spring is provided between the pressure ring and the connecting plate.

[0012] Furthermore, multiple sealing blocks are slidably embedded in the inner wall of the lower end of the outer cylinder. Each sealing block has a sliding pin fixed on its back. The sliding pin slidably penetrates the side wall of the outer cylinder, and when all the sealing blocks slide in the axial direction, the adjacent sealing blocks fit together.

[0013] Furthermore, a return spring is provided between the end of the sliding pin and the outer wall of the outer cylinder, and the return spring provides elastic force to make the sealing block slide in the axial direction.

[0014] Furthermore, the upper surface of the sliding pin is an inclined surface that slopes downwards towards the axis.

[0015] Furthermore, a rubber pad is provided in the lower end face of the sealing block.

[0016] Furthermore, the lifting tube is slidably connected to the drive motor, and a second shift fork is provided in the lifting tube.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] In this invention, the lint on the surface of the mop mat is the main interfering factor affecting the measurement of sealing and air permeability. This device automatically scrapes off the lint in the test area before testing and uses a retractable sealing block assembly to form an annular sealing cavity that perfectly fits the scraped area. This fundamentally solves the industry problem of air leakage from the contact surface between the pressure gauge and the sample, ensuring that all injected air must pass vertically through the mop mat base fabric itself. This allows the data collected by the air pressure sensor to reflect the true air permeability of the mop mat, greatly improving the accuracy and repeatability of the test data.

[0019] In this invention, multiple steps such as sample fixation, scraping, sealing, inflation, and testing are integrated into a single, continuous operation. Users only need to place the sample, operate the fork, and press the start button to complete complex tests, which greatly reduces the reliance on the operator's technical skills and labor intensity. The mechanically driven scraping and sealing processes are rapid and consistent, much faster than traditional methods of manually preparing samples and ensuring sealing, significantly improving the efficiency of batch testing.

[0025] Please see Figures 1-4In this embodiment of the invention, a novel material textile cleaning pad air permeability testing device includes a base 1, a support plate 2 fixed on the base 1, two connecting shafts 3 fixed to the base 1 mounted above the support plate 2, a connecting plate 31 below the connecting shafts 3, an outer cylinder 4 fixed in the connecting plate 31, an inner cylinder 5 inside the outer cylinder 4, a lifting pipe 6 that slides through the outer cylinder 4 fixed at the upper end of the inner cylinder 5, a through hole concentric with the outer cylinder 4 in the center of the support plate 2, a cover plate 21 below the support plate 2 that can close the through hole, and a support telescopic cylinder 22 connected to the cover plate 21.

[0026] The lifting pipe 6 is connected to the air pump. An air pressure sensor is installed inside the inner cylinder 5. When the mop is placed on the support plate 2 and the outer cylinder 4 is pressed on the mop, the air pump injects initial air pressure into the inner cylinder 5 through the lifting pipe 6. After the cover plate 21 is opened by the support telescopic cylinder 22, the air in the inner cylinder 5 is released from the through hole through the mop to the bottom of the support plate 2. The air pressure sensor detects the drop in air pressure and can detect the air permeability of the mop.

[0027] In this embodiment, the lower edge of the inner cylinder 5 is provided with serrations 51, and the upper end of the lifting pipe 6 is connected to a drive motor 7.

[0028] In other words, by driving the inner cylinder 5 to rotate through the drive motor 7 and the lifting tube 6, the saw teeth 51 can scrape off the lint at the corresponding position on the top of the mop mat, improve the fit, and prevent air from leaking from the top of the mop mat.

[0029] In this embodiment, an extension shaft 35 is slidably provided at the lower end of the connecting shaft 3, and the lower end of the extension shaft 35 is fixed to the connecting plate 31. A fixing plate 34 is fixed above the outer cylinder 4, and the fixing plate 34 is fixed to the extension shaft 35.

[0030] In this embodiment, the outer wall of the outer cylinder 4 is hinged with a first fork 41.

[0031] In other words, the outer cylinder 4 can be driven to rise and fall by the first fork 41, and the extension shaft 35, the fixed plate 34, and the connecting plate 31 also rise and fall accordingly.

[0032] In this embodiment, a sliding shaft 32 is slidably provided at the lower end of the extension shaft 35, and the lower end of the sliding shaft 32 is fixed on the pressure ring 8. A support spring 33 is provided between the pressure ring 8 and the connecting plate 31.

[0033] When the outer cylinder 4 descends, the pressure ring 8 first presses on the mop pad and compresses the support spring 33, thereby fixing the mop pad.

[0034] In this embodiment, multiple sealing blocks 42 are slidably embedded in the inner wall of the lower end of the outer cylinder 4. Each sealing block 42 has a sliding pin 43 fixed on its back. The sliding pin 43 slidably penetrates the side wall of the outer cylinder 4, and when all the sealing blocks 42 slide in the axial direction, the adjacent sealing blocks 42 fit together.

[0035] In this embodiment, a return spring 44 is provided between the end of the sliding pin 43 and the outer wall of the outer cylinder 4. The return spring 44 provides elastic force to make the sealing block 42 slide in the axial direction.

[0036] In this embodiment, the upper surface of the sliding pin 43 is an inclined surface that slopes downward toward the axis.

[0037] In other words, when the inner cylinder 5 slides downward, it pushes the sliding pin 43 away from the axis along the inclined surface of the sliding pin 43, so that the sliding pin 43 is embedded in the inner wall of the outer cylinder 4. At this time, the rotation of the inner cylinder 5 can scrape off the lint on the mop. When the inner cylinder 5 rises to the bottom and is higher than the upper end of the sliding pin 43, each sealing block 42 slides towards the axis under the action of the return spring 44, thus forming a ring on the mop where the lint has been scraped off, and playing a sealing role.

[0038] In this embodiment, a rubber pad is provided in the lower end face of the sealing block 42. This further improves the sealing effect between the sealing block 42 and the mop pad.

[0039] In this embodiment, the lifting tube 6 is slidably connected to the drive motor 7, and a second fork 61 is provided in the lifting tube 6. The second fork 61 can pull the lifting tube 6 up and down, thereby raising and lowering the inner cylinder 5.

[0040] In practice, by raising the first fork support telescopic cylinder 41, the entire assembly of the outer cylinder support telescopic cylinder 4, inner cylinder support telescopic cylinder 5, and pressure ring support telescopic cylinder 8 is raised, laying the mop sample flat on the surface of the support plate support telescopic cylinder 2. Then, the first fork support telescopic cylinder 41 is pressed down, and the pressure ring support telescopic cylinder 8 will first contact the mop sample. Continuing to press down, the pressure ring support telescopic cylinder 8 will compress the sample and press it firmly against the support plate support telescopic cylinder 2. Simultaneously, the support spring support telescopic cylinder 33 is compressed, providing a stable and gentle clamping force to ensure the sample does not shift during testing.

[0041] Operate the second shift fork support telescopic cylinder 61, pushing the lifting tube support telescopic cylinder 6 downwards, thereby driving the inner cylinder support telescopic cylinder 5 to press down. When the inner cylinder support telescopic cylinder 5 moves downwards, its cylinder wall will press against the inclined surface at the upper end of the sliding pin support telescopic cylinder 43. This pressing force will overcome the elastic force of the return spring support telescopic cylinder 44, pushing all the sealing block support telescopic cylinders 42 to slide outwards in a direction away from the axis, causing them to retract into the inner wall of the outer cylinder support telescopic cylinder 4. At this time, the rubber pad at the lower end of the sealing block detaches from the surface of the mop, and the drive motor support telescopic cylinder 7 is started. The motor drives the inner cylinder support telescopic cylinder 5 to rotate through the lifting tube support telescopic cylinder 6. The rotating inner cylinder support telescopic cylinder 5 and the serrated support telescopic cylinder 51 at its lower edge will scrape off the lint on the surface of the mop at the corresponding position below, forming a smooth annular area to ensure the sealing of subsequent tests. After scraping is completed, the drive motor support telescopic cylinder 7 is stopped, and the second shift fork support telescopic cylinder 61 is operated to lift the lifting tube support telescopic cylinder 6 and the inner cylinder support telescopic cylinder 5 upward, so that its bottom rises to a position slightly higher than the upper end of the sliding pin support telescopic cylinder 43. Once the compression is released, the elastic force of the return spring support telescopic cylinder 44 will push all the sealing block support telescopic cylinders 42 to slide back to the axis. The adjacent sealing block support telescopic cylinders 42 fit together, and the rubber pads at their lower ends are tightly pressed on the annular area where the lint has just been scraped off, forming a sealed annular chamber.

[0042] Ensure that the cover plate support telescopic cylinder 21 is in the closed state under the action of the support telescopic bar support telescopic cylinder 22, seal the through hole in the center of the support plate support telescopic cylinder 2, start the air pump, and inject the pre-set initial air pressure into the sealed space surrounded by the inner cylinder support telescopic cylinder 5, the floor mat sample scraping area, and the sealing block support telescopic cylinder 42 through the lifting pipe support telescopic cylinder 6. After the air pressure stabilizes, open the cover plate support telescopic cylinder 21 by controlling the support telescopic bar support telescopic cylinder 22, exposing the through hole in the center of the support plate support telescopic cylinder 2. At this time, the compressed air in the inner cylinder support telescopic cylinder 5 begins to be released to the bottom of the support plate through the floor mat sample and the through hole. The built-in air pressure sensor begins to monitor and record the curve and data of the air pressure in the sealed chamber decreasing over time in real time. Based on the rate of air pressure decrease, such as the air pressure decrease value per unit time, or the time required to reach a certain pressure, the air permeability of the floor mat sample can be calculated. The faster the rate of descent, the better the breathability.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
