Description

Technical Field

[0001] This utility model relates to the field of woven fabric quality inspection technology, and in particular to a woven fabric quality inspection device. Background Technology

[0002] Woven fabric is a flexible material made of polypropylene / polyethylene flat filaments woven together. It features high tensile strength, corrosion resistance, and low cost, and is widely used in packaging bags, geotextiles, and agricultural coverings. Its mesh structure allows for breathability and waterproofing by adjusting the weaving density. Microporous woven bags rely on micropores on the fabric surface for breathability and preservation; uneven pore distribution reduces bag strength and increases the risk of breakage.

[0003] Chinese patent discloses a breathability testing device for woven fabric (authorization announcement number CN215218478U). This patented technology includes a gas supply device, a accommodating tank, and a through-type housing connected in sequence. The through-type housing is located at the top of the accommodating tank. A first sealing gasket abuts against the top of the accommodating tank, and a second sealing gasket, which cooperates with the first sealing gasket, abuts against the bottom of the through-type housing. A locking member is fixedly installed on the outer wall of the accommodating tank, and a locking part, which cooperates with the locking member, is fixedly installed on the outer wall of the through-type housing. When the woven fabric is tested for breathability, the fabric is sandwiched between the first and second sealing gaskets, and the locking part locks with the locking member. Water is then poured into the through-type housing, and the gas supply device is activated to supply air, allowing observation of the air bubbles in the water. This method is used to test the breathability of the woven fabric, and the perforation equipment can be further adjusted based on the breathability results to meet the perforation quality requirements.

[0004] However, this patent still has shortcomings. While it detects the pores of a woven bag by venting air through water and observing the distribution of air bubbles, it cannot test the bag's abrasion resistance and toughness during this process. When used with microporous woven bags, the bag is subjected to real-time friction during this process, and monitoring the condition of the pores during this friction is crucial for assessing the quality of the woven fabric. Therefore, those skilled in the art have provided a woven fabric quality testing device to address the problems mentioned in the background section. Utility Model Content

[0005] 1. Technical Solution

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a woven fabric quality inspection device, comprising an upper frame, a lower housing, hydraulic rod two, hydraulic rod three, an upper mounting frame, and a lower mounting frame. The upper frame is located above the lower housing. Symmetrically distributed hydraulic rod twos are arranged inside both ends of the upper frame. The upper mounting frame is located at the lower end of each hydraulic rod two. An upper pressure plate is located inside the upper mounting frame. A connecting plate is located at the upper end of the upper pressure plate. A rectangular frame is located at one end of the connecting plate. Gear plates are arranged relatively distributed on the inner wall of the rectangular frame. A motor is located on one side of the upper end of the upper mounting frame. An intermittent gear located inside the rectangular frame and intermittently meshing with the gear plates is located at the output end of the motor. Lower mounting frames are located inside both ends of the lower housing. Lower support plates are located inside the lower mounting frames. Symmetrically distributed slides are located at the upper end of the lower mounting frames. Springs are arranged between the lower support plates and the slides. An air pump with its output end penetrating the lower housing is located at one end of the lower housing.

[0008] Furthermore, each end of the upper pressure plate is provided with a guide rod, and each end of the upper mounting frame is embedded with a sliding sleeve. The guide rod is slidably installed inside the sliding sleeve, and a ball bearing that rolls against the inner wall of the upper end of the upper mounting frame is rotatably installed on the upper end of the upper pressure plate.

[0009] Specifically, guide rod one slides inside the sliding sleeve, and guides the upper pressure plate during movement. The ball bearings prevent the upper pressure plate from flipping over by guide rod two.

[0010] Furthermore, guide rods are provided at both the front and rear ends of the lower support plate, and through holes are embedded inside the slide block. The guide rods are slidably inserted into the through holes and located inside the spring;

[0011] Specifically, the second guide rod slides inside the through hole, providing sliding support for the reciprocating lower support plate. During the extension and retraction of the spring, the second guide rod slides inside the spring, guiding the spring and preventing it from deviating.

[0012] Furthermore, the upper end of the lower mounting frame is provided with a guide rail, and the lower end of the lower support plate is provided with a slider that is slidably installed inside the guide rail. The slider is rotatably installed with equidistantly distributed balls that slide against the inner wall of the groove.

[0013] Specifically, the lower support plate slides inside the guide rail via a slider, which guides the lower support plate. The ball bearings roll and fit against the guide rail, improving the smoothness of sliding and reducing friction and resistance.

[0014] Furthermore, a mounting bracket is fitted onto the outer wall of the lower housing, a rectangular sealing gasket is provided at the upper end of the lower housing, and a hydraulic rod is provided at both ends of the lower housing, with a connecting block connected to the upper frame at the telescopic end of the hydraulic rod.

[0015] Specifically, the sealing gasket improves the sealing performance of the woven fabric clamping point during use to prevent liquid leakage. The connecting block is driven to move longitudinally via a hydraulic rod, which in turn drives the upper frame to move longitudinally.

[0016] Furthermore, a flow guide hopper is provided at the lower end of the lower housing, and a discharge pipe controlled by a valve is provided at the lower end of the flow guide hopper;

[0017] Specifically, the valve controls the opening and closing of the discharge pipe, and when water is discharged from the inner wall of the lower box and the upper frame, the water is guided by the guide bucket.

[0018] 2. Beneficial effects

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] In this invention, a woven fabric is sandwiched between an upper frame and a lower box. Water is injected into the upper frame and the lower box, with the water level higher than the woven fabric. An air pump introduces gas into the water, and the air bubbles form bubbles on the water surface through the holes inside the woven fabric. The distribution of the air bubbles indicates the opening of the woven fabric.

[0021] Meanwhile, the upper pressure plate and the lower support plate are in contact, and the motor drives the intermittent gear to rotate. Through intermittent meshing with two sets of toothed plates, the rectangular frame moves back and forth. The friction force drives the lower support plate to move synchronously. When the woven fabric is tested for holes, the friction during use is simulated. By testing the woven fabric for friction, we can understand the stability of the holes in the woven fabric during actual use, as well as the wear resistance and toughness of the woven fabric, thereby improving the reference value of the woven fabric test data.

[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0037] Example 1

[0038] Please see Figure 1-7As shown, this embodiment is a woven fabric quality inspection device, including an upper frame 1, a lower housing 2, hydraulic rods 5 and 6, an upper mounting frame 11, and a lower mounting frame 12. The upper frame 1 is located above the lower housing 2. Hydraulic rods 5 are symmetrically distributed inside both ends of the upper frame 1. The upper mounting frame 11 is located at the lower end of the hydraulic rods 5. An upper pressure plate 13 is located inside the upper mounting frame 11. A connecting plate 19 is located at the upper end of the upper pressure plate 13. A rectangular frame 16 is located at one end of the connecting plate 19. The inner wall of the rectangular frame 16 is provided with... There are relatively distributed toothed plates 20. A motor 17 is provided on one side of the upper end of the upper mounting frame 11. An intermittent gear 18 located inside the rectangular frame 16 and intermittently meshes with the toothed plates 20 is provided at the output end of the motor 17. Lower mounting frames 12 are provided inside both ends of the lower housing 2. A lower support plate 14 is provided inside the lower mounting frame 12. A symmetrically distributed slide block 22 is provided at the upper end of the lower mounting frame 12. A spring 29 is provided between the lower support plate 14 and the slide block 22. An air pump 28 with its output end penetrating through the lower housing 2 is provided at one end of the lower housing 2.

[0039] Guide rods 15 are provided at both ends of the upper pressure plate 13. Sliding sleeves 21 are embedded in both ends of the upper mounting frame 11. The guide rods 15 are slidably installed inside the sliding sleeves 21. A ball bearing 26 is rotatably installed on the upper end of the upper pressure plate 13 and rolls against the inner wall of the upper end of the upper mounting frame 11.

[0040] Guide rods 23 are provided at both the front and rear ends of the lower support plate 14, and through holes 27 are embedded inside the slide block 22. The guide rods 23 are slidably inserted into the through holes 27 and located inside the spring 29;

[0041] The upper end of the lower mounting frame 12 is provided with a guide rail 24, and the lower end of the lower support plate 14 is provided with a slider 25 that is slidably installed inside the guide rail 24. Inside the slider 25, there are equidistantly distributed balls 26 that slide against the inner wall of the groove.

[0042] The lower housing 2 is fitted with a mounting bracket 4 on its outer wall. A rectangular sealing gasket 7 is provided at the upper end of the lower housing 2. Hydraulic rods 3 are provided at both ends of the lower housing 2. A connecting block 10 connected to the upper frame 1 is provided at the telescopic end of the hydraulic rods 3.

[0043] The lower end of the lower housing 2 is provided with a guide hopper 8, and the lower end of the guide hopper 8 is provided with a discharge pipe 9 whose opening and closing is controlled by a valve.

[0044] In this embodiment, the fabric to be tested is placed on the lower support plate 14 of the lower box 2. The hydraulic rod 3 drives the upper frame 1 to press down, and the upper frame 1 is tightly attached to the upper end of the lower box 2 through the sealing gasket 7 to form a closed testing space, ensuring that no liquid or gas leaks during the testing process. Clean water is injected into the lower box 2, and the water level must completely cover the surface of the woven fabric. The air pump 28 is started, and gas is continuously introduced into the closed space through the pipeline. The gas escapes through the micropores of the woven fabric and forms bubbles on the water surface. The hydraulic rod 5 in the upper frame 1 drives the upper mounting frame 11 to press down, so that the upper pressure plate 13 is in close contact with the upper surface of the woven fabric.

[0045] Motor 17 drives intermittent gear 18 to rotate. The gear intermittently meshes with toothed plates 20 on both sides of rectangular frame 16, causing rectangular frame 16 and upper pressure plate 13 to move horizontally back and forth. Upper pressure plate 13 drives lower support plate 14 to move synchronously through friction. Lower support plate 14 slides along guide rail 24 through slider 25. Guide rod 23 guides in through hole 27 of slide block 22 to ensure smooth movement. Spring 29 provides elastic support force for the reset of lower support plate 14, simulating the actual working condition of woven fabric under friction during use.

[0046] The air permeability test assesses the uniformity and air permeability of the woven fabric's pores by observing the distribution density, size, and escape velocity of air bubbles on the water surface. The abrasion resistance test evaluates its abrasion resistance and toughness by observing whether the pores enlarge after friction and whether the woven fabric surface becomes fuzzy or cracked. After the tests are completed, the drain pipe valve 9 is opened, and the liquid is discharged through the guide bucket 8.

[0047] Through air permeability testing and abrasion simulation, a multi-dimensional quality assessment was achieved. The air permeability testing follows the principle of the bubble method, using an air pump 28 to ventilate a closed water environment. The bubble visualization presents the pore characteristics, directly reflecting the air permeability and pore quality of the woven fabric. The abrasion simulation uses a mechanism of motor 17, intermittent gear 18, and toothed plate 20 to drive the upper pressure plate 13 to reciprocate, combined with the synchronous sliding of the lower support plate 14, to simulate the pore deformation or material damage caused by friction in actual use of the woven fabric, accurately assessing its abrasion resistance and structural toughness.

[0048] Compared to traditional single air permeability testing devices, this device can complete air permeability, abrasion resistance, and toughness tests under the same working conditions, reducing repeated clamping time and improving efficiency. It also reproduces the dynamic process of stress on woven fabric during use through mechanical friction, making the test data closer to actual application scenarios.

[0049] Addressing the shortcomings of existing technologies that can only detect air permeability but cannot assess abrasion resistance and toughness, this device integrates a friction simulation mechanism to solve the quality risk of pore failure, such as bag breakage, caused by friction in the actual use of microporous woven fabrics. Its dynamic friction detection can assess pore stability and material durability, providing data support for the debugging of perforation equipment and ensuring that the woven fabric achieves a balance between air permeability and preservation function and structural strength.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
