Description

Technical Field

[0001] The invention relates to textile testing technology, and in particular to a textile air permeability testing device provided with a stable stretching structure. Background Art

[0002] Textiles are products processed through textiles, including yarn, woven fabrics, knitted fabrics, braided fabrics, etc., which are divided into two categories: woven fabrics and knitted fabrics. China is one of the earliest countries in the world to produce textiles. With the development of society, the iteration of textile technology and the increasing consumption level of people, the market demand for high-density textiles is also increasing. High-density textiles refer to textiles with a warp and weft density of more than 200. High-density textiles have the advantages of fine texture, strong flexibility, good drape and unique patterns. Therefore, clothing and other items made of high-density textiles are also deeply loved by people.

[0003] A Chinese invention patent with publication number CN118603844A discloses a textile quality detection device, which is used in combination with an air supply component and an airflow detector to allow airflow to pass through the textile, so that the airflow detector detects the amount of air passing through the textile, thereby judging the air permeability of the textile and increasing the function of the detection device. At the same time, the lifting cross seat is driven upward by an electric telescopic rod, so that the lifting rod drives the positioning bottom frame upward, which is convenient for adjusting the distance between the textile and the airflow detector, thereby detecting the amount of airflow at different distances and improving the practicality of use.

[0004] When the existing equipment is in use, the textile may undergo not only static angle changes but also dynamic angle changes during the stretching process, which makes it impossible to simulate the stretching of different textiles at different angles in actual use.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Example: See Figure 1-Figure 8 A textile air permeability testing device with a stable stretching structure includes a base 1, a support column 11 is arranged at the upper end of the base 1, and an adjustment component 2 is arranged at the upper end of the support column 11 for stretching the textile.

[0039] In this solution, the inner cavity of the support column 11 is provided with a device with power output such as a motor, and is connected to an external control device. When the motor is started, it synchronously drives the turntable 24 arranged at its output end to rotate.

[0040] Furthermore, the adjustment component 2 includes a base plate 21 connected to the support column 11, and multiple groups of guide grooves 22 are opened at the upper end of the base plate 21, and the multiple groups of guide grooves 22 are evenly distributed at the end of the base plate 21, and a movable rod 23 is slidably installed on the inner wall of the guide groove 22.

[0041] In this embodiment, when the turntable 24 rotates, it cooperates with the slide rod 26 to move, thereby synchronously driving the movable rod 23 set at the lower end of the slide rod 26 to move. The movable rod 23 moves to support the inner wall of the textile, so that the textile is in a taut state, and the position of the movable rod 23 is adjusted according to the actual situation to make it suitable for different scenes.

[0042] Furthermore, a turntable 24 is rotatably mounted on the upper end of the bottom plate 21 , and an arc groove 25 corresponding to the guide groove 22 is opened on the upper end of the turntable 24 . At the same time, a slide bar 26 is slidably mounted on the inner wall of the arc groove 25 , and the lower end of the slide bar 26 is connected to the upper end of the movable rod 23 .

[0043] Specifically, the upper end of the support column 11 penetrates and extends to the upper end of the bottom plate 21 , and the upper end of the support column 11 is connected to the turntable 24 , so that the turntable 24 is driven to rotate by the support column 11 .

[0044] Since an arc groove 25 is provided at the upper end of the rotating disk 24 , when the rotating disk 24 rotates, the arc groove 25 drives the slide bar 26 to move, and drives the slide bar 26 to expand outward or move toward the middle according to actual conditions.

[0045] Furthermore, a pressing component 3 is assembled at the end of the adjusting component 2, and partially squeezes the stretched textile through the pressing component 3; the pressing component 3 includes a driving member 31 connected to the end of the movable rod 23, and a fixing plate 32 is provided at the end of the driving member 31. The output end of the driving member 31 passes through and extends to the other end of the fixing plate 32, and a limiting plate 33 is provided at the end of the fixing plate 32, and a movable groove 34 is provided on the inner wall of the limiting plate 33.

[0046] In this embodiment, the driving member 31 is a device with power output such as a motor, and is connected to an external control device. When the driving member 31 is started, it synchronously drives the adjustment plate 35 arranged at its output end to rotate.

[0047] At the same time, the movable groove 34 is further limited by the limiting plate 33, and the limiting block 38 is supported by the limiting plate 33, so that the limiting block 38 remains stable, wherein the cross section of the movable groove 34 is irregular.

[0048] Furthermore, an adjustment plate 35 is provided at the output end of the driving member 31, a slot 36 is provided at the end of the adjustment plate 35, a limit block 38 is provided at the end of the limit plate 33, an extension rod 37 is slidably mounted on the inner wall of the limit block 38, and an arc plate 39 is provided at the end of the extension rod 37. A positioning block 371 is provided at one end of the extension rod 37 close to the adjustment plate 35, and the outer surface of the positioning block 371 is slidably connected to the inner wall of the movable groove 34.

[0049] Specifically, when the driving member 31 is started, the adjusting plate 35 is driven to rotate. Since a slot 36 is provided at the end of the adjusting plate 35, and the inner wall of the slot 36 is slidingly connected to the outer surface of the positioning block 371, and the outer surface of the positioning block 371 is slidingly connected to the inner wall of the movable groove 34, when the adjusting plate 35 moves, the positioning block 371 is synchronously driven to move along the inner wall of the movable groove 34.

[0050] The limit block 38 is rotatably installed on the limit plate 33, and the extension rod 37 is limited by the limit block 38, so that when the extension rod 37 moves, it rotates around the end of the limit block 38, thereby synchronously driving the arc plate 39 set at the end of the extension rod 37 to move, and further stretching the inner wall of the textile, thereby simulating the state of storing items inside the textile.

[0051] Furthermore, an adjusting rod 12 is provided at the edge of the upper end of the base 1, a clamping plate 13 is provided at the upper end of the adjusting rod 12, and a limiting component 4 is provided at the end of the clamping plate 13, and the upper end of the textile is limited by the limiting component 4. The limiting component 4 includes a ring 41 connected to the clamping plate 13, and a sleeve 42 is provided on the inner wall of the ring 41.

[0052] In this embodiment, the clamping plate 13 is slidably installed on the outer surface of the adjusting rod 12, and the height of the clamping plate 13 is adjusted according to the actual situation. At the same time, the end of the clamping plate 13 is provided with a fixing component such as a clamp, which is used to fix the clamping plate 13.

[0053] At the same time, the end of the clamping plate 13 is connected to the ring 41, and the ring 41 is composed of two semicircular locking blocks. The inner wall of the locking block is provided with rubber blocks and other anti-slip components. A pin is provided at the joint of the two semicircular locking blocks to fix the sleeve 42.

[0054] The upper end of the base 1 is provided with a plurality of holes, and the inner wall of each hole can be snapped onto the outer surface of the adjusting rod 12 , and the position of the adjusting rod 12 can be adjusted according to the actual situation to make it suitable for the current scene.

[0055] Furthermore, a fixed block 43 is provided at the upper end of the sleeve 42, and a screw 44 is rotatably installed at the end of the fixed block 43, and the end of the screw 44 penetrates and extends to the other end of the fixed block 43. The outer surface of the sleeve 42 is symmetrically provided with a slide groove 421. A movable block 45 is slidably installed on the inner wall of the sleeve 42, and the upper end of the movable block 45 is connected to the lower end of the screw 44. A positioning shaft 451 is provided on the outer surface of the movable block 45, and the outer surface of the positioning shaft 451 is slidably connected to the inner wall of the slide groove 421.

[0056] Specifically, when the screw rod 44 rotates, the movable block 45 arranged at its lower end is synchronously driven to move, wherein the inner wall of the fixed block 43 is provided with a threaded groove, and the lower end of the fixed block 43 is rotatably connected to the upper end of the sleeve 42, and the screw rod 44 is supported by the fixed block 43.

[0057] At the same time, the positioning shaft 451 on the outer surface of the movable block 45 is slidably connected with the inner wall of the slide groove 421, thereby limiting the moving trajectory of the movable block 45, thereby ensuring that the movable block 45 will not fall off during movement.

[0058] Furthermore, the outer surface of the movable block 45 is provided with a plurality of grooves 452, and the plurality of grooves 452 are evenly distributed on the outer surface of the movable block 45. An extrusion block 46 is rotatably mounted on the inner wall of the groove 452, and the cross section of the lower end of the extrusion block 46 is conical.

[0059] Specifically, when the movable block 45 moves, the extrusion block 46 is synchronously driven to move, and during the movement of the extrusion block 46, the lower end of the extrusion block 46 is engaged with the inner wall of the collar.

[0060] The collar is used to limit the end of the textile, so that the outer surface of the textile passes through the inner wall of the collar and fits with the outer surface of the lower end of the extrusion block 46, thereby ensuring that the textile remains stable as a whole during testing.

[0061] Furthermore, the inner wall of the sleeve 42 is provided with a protrusion 422 corresponding to the extrusion block 46, and the outer surface of the protrusion 422 is in contact with the outer surface of the extrusion block 46. The outer surfaces of the multiple groups of extrusion blocks 46 are sleeved with rubber rings 47.

[0062] Specifically, one end of the protrusion 422 close to the extrusion block 46 is inclined, so that when the extrusion block 46 moves downward, the outer surface of the extrusion block 46 fits with the outer surface of the protrusion 422, and drives the extrusion block 46 to rotate around the connection between it and the groove 452, so that the lower end of the extrusion block 46 expands outward and engages with the inner wall of the ring, thereby ensuring the overall stability of the textile.

[0063] At the same time, after the detection is completed, the extrusion block 46 is limited by the rubber ring 47 mounted on it. When the movable block 45 moves upward, the force of the rubber ring 47 causes the extrusion block 46 to move toward the middle, and then separate from the part that is in contact with the textile, so that the textile after detection can be taken out easily.

[0064] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (MicrocontrollerUnit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but the storage capacity is small, the input and output interface is simple, and the function consumption is low.

[0065] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
