Description

Technical Field

[0001] This application relates to the technical field of equipment for fabric quality inspection, and more specifically, to a fabric strength testing device and its usage method. Background Technology

[0002] In order to assess the quality of fabric and determine whether it meets the prescribed standards, manufacturers need to test the strength of the fabric during production. Generally, a fabric strength testing device is used to perform tensile testing on the fabric. However, fixing the fabric during testing is quite cumbersome, and unevenness of the fabric may affect the test results.

[0003] Existing technology publication CN215492888U discloses a fabric strength testing device for protective clothing processing. This device clamps both ends of the fabric to the clamping sides of a rotating rod and pressure plate. Rotating the rod and pressure plate wraps one end of the fabric around its outer surface to secure it. A pressure ball is then pushed against the upper surface of the fabric, and a pressure sensor detects the pressure to calculate the fabric's tear strength. While this fabric fixing method achieves reliable fixation, it requires manual clamping of both ends when testing different fabrics. When testing a large number of fabrics, this method is not only labor-intensive for workers but also results in slow testing speed and low efficiency. In the existing technology CN112763337A, a cylinder is used to push the clamping frame to one side to clamp and pull the fabric. However, the pressing of the other end of the fabric still requires manual operation during the flattening and pulling test. Although CN114136759A can simultaneously clamp one end of the fabric and press down the roller at the other end through an electric push rod, and make the roller rotate to pull the fabric to test the fabric strength, when testing multiple fabric samples, the staff still needs to remove the previous sample from the placement plate and lay the next sample to be tested flat on the placement plate before the next test can be carried out. The improvement in testing efficiency is not good. Summary of the Invention

[0004] 1. Technical problems to be solved

[0005] The purpose of this application is to provide a fabric strength testing device and its usage method, which solves the technical problems that can only be solved by existing technologies and achieves the desired technical effect.

[0006] 2. Technical Solution

[0007] This application provides a fabric strength testing device, including a housing. A pressure ball is slidably disposed inside the housing, and a pressure sensor is provided on the pressure ball for monitoring the pressure applied by the pressure ball to the fabric. A fabric feeding assembly is installed inside the housing, and the fabric feeding assembly includes a storage box. A placement rack for placing fabric is slidably installed inside the storage box. A distribution tube is also slidably installed inside the housing. Two fabric picking cylinders are installed on one side of the distribution tube. The fabric picking cylinders are densely covered with perforations. The fabric picking cylinders are connected to the inner cavity of the distribution tube. The distribution tube is connected to the suction end of an induced draft fan. The fabric picking cylinders are connected to a lifting mechanism, which is used to drive the fabric picking cylinders to move up and down, so that the fabric is moved to the testing position. A rotating mechanism is also installed on one side of the distribution tube. The rotating mechanism is connected to the fabric picking cylinders and is used to drive the fabric picking cylinders to rotate during the lifting movement, so that the fabric is automatically wound around the fabric picking cylinders.

[0008] By employing the above technical solution, a negative pressure is created inside the fabric collection tube under the action of the induced draft fan, generating suction at the leakage point to adsorb the fabric to be tested. Under the action of the lifting mechanism, the fabric collection tube carries the fabric to be tested upwards a certain distance, and under the action of the rotating mechanism, the fabric is wrapped around the outside of the collection tube. Under the action of the cylinder, the pressure ball then performs a strength test on the fabric. This method eliminates the need for frequent manual clamping of the fabric, greatly improving the efficiency of fabric strength testing.

[0009] As an optional solution to the technical solution of this application, the lifting mechanism includes two receiving plates fixedly installed in the housing, and a first limiting groove is provided on the receiving plate, and the cloth picking cylinder is movably connected in the first limiting groove.

[0010] By adopting the above technical solution, the cloth tube is limited to lift and slide within the first limiting groove opened on the receiving plate.

[0011] As an optional solution to the technical solution of this application, the receiving plate is also provided with an inclined groove, which is connected to the lower side of the first limiting groove. A driving plate is fixed on one side of the distribution pipe, and two driving grooves are provided on the driving plate. The limiting pipe slides and rotates simultaneously in the corresponding driving groove and the inclined groove or the driving groove and the first limiting groove.

[0012] By adopting the above technical solution, under the combined action of the inclined groove and the driving groove, the limiting tube is pushed to move upward and towards the middle of the driving plate, so that the cloth taking cylinder can move from both ends of the cloth to the middle and wrap the cloth around the cloth taking cylinder, making the cloth wrapped and fixed more firmly and flat. Then, the cloth taking cylinder and the cloth rise synchronously.

[0013] As an optional solution to the technical solution of this application, a unfolding mechanism is also installed on one side of the distribution tube. The unfolding mechanism is used to drive the cloth taking tubes on both sides to move in a straight line in opposite directions. The unfolding mechanism includes a second limiting groove opened on the receiving plate. The second limiting groove is set with an inclined structure. The second limiting groove is connected to the upper side of the first limiting groove. The limiting tube is slidably connected to the corresponding second limiting groove.

[0014] By adopting the above technical solution, when the driving plate moves the limiting tube and the cloth taking tube along the first limiting groove to the second limiting groove, the limiting tube then moves the cloth taking tube along the second limiting groove and moves the cloth taking tube to both sides. The cloth taking tube will cause the cloth to unfold to both sides, so that the cloth is in a taut state, ensuring the accuracy of the test results.

[0015] As an optional solution to the technical solution of this application, the rotating mechanism includes a gear fixedly sleeved on the limiting tube, the gear meshing with a corresponding rack, the rack being fixedly mounted on the receiving plate, and a limiting mechanism being installed on the receiving plate. The limiting mechanism includes a toothed plate slidably connected to the receiving plate, and a plurality of elastic elements are fixedly connected between the toothed plate and the receiving plate, and the gear meshes with the toothed plate.

[0016] By adopting the above technical solution, when the gear and the rack come into contact, the gear will drive the limiting tube and the fabric taking tube to rotate because the gear meshes with the corresponding rack. This causes the edge of the fabric to wrap around the fabric taking tube, which on the one hand makes the fabric more secure, and on the other hand makes the fabric more taut, which is conducive to the smooth progress of strength testing.

[0017] As an optional solution to the technical solution of this application, a three-way pipe is connected between the distribution pipe and the suction end of the induced draft fan. A baffle is slidably installed inside the three-way pipe. A ventilation opening is provided on one side of the baffle. Two push plates are fixedly installed on the upper and lower sides inside the housing. The push plates are in movable contact with the baffle and are used to switch the conduction path of the three-way pipe.

[0018] By adopting the above technical solution, when the distribution tube moves upward and the baffle tube contacts the upper push plate, the baffle tube moves downward under the action of the push plate, blocking one side of the three-way tube. At this time, the fabric taking cylinder is no longer in a negative pressure state. When the distribution tube and the baffle tube move downward, the fabric taking cylinder will reverse, so that the fabric on the fabric taking cylinder will automatically detach from the fabric taking cylinder, eliminating the need for staff to manually remove the fabric, and further improving the efficiency of fabric strength testing.

[0019] As an optional solution to the technical solution of this application, a limiting cylinder is fixedly installed on the distribution pipe, a connecting rod is slidably connected inside the limiting cylinder, a plurality of mounting grooves are provided on the connecting rod, a limiting ball block is slidably connected inside the mounting groove, a spring is fixedly connected between the limiting ball block and the mounting groove, and a plurality of limiting grooves adapted to the limiting ball block are provided inside the limiting cylinder, and the limiting ball block and the limiting grooves are in frictional contact.

[0020] By adopting the above technical solution, the setting of the limiting ball block, the limiting groove, and the spring can increase the friction and prevent the stop tube from moving randomly.

[0021] As an optional solution to the technical solution of this application, a dust suction nozzle is fixedly connected to the other end of the baffle pipe, a receiving box is provided between the suction end of the blower and the three-way pipe, a sealing cover is inserted on the receiving box, and a filter screen is installed inside the receiving box.

[0022] By adopting the above technical solution, when the baffle pipe blocks the distribution pipe, the suction nozzle is immediately under negative pressure, and the fabric debris generated during the test enters the receiving box through the suction nozzle for collection, thus fully ensuring the cleanliness of the testing environment.

[0023] As an optional solution to the technical solution of this application, the placement rack is constrained by the storage box and slidably connected to it. The cloth placement assembly also includes several rotating frames fixedly installed on both sides of the storage box and counterweights slidably connected to both sides of the storage box. A connecting rope is fixedly connected between the counterweights and the placement rack.

[0024] By adopting the above technical solution, the staff neatly stacks a specified number of fabrics on the placement rack. As the amount of fabric decreases, the placement rack gradually moves the fabrics upward under the action of the counterweight, so that the topmost fabric is always in the same position, making it convenient for the fabric retrieval tube to take the fabric.

[0025] The method of using the fabric strength testing device includes the following steps:

[0026] a. Place the fabric to be tested on the rack. Under the weight of the fabric, the rack moves downward and the counterweight moves upward.

[0027] b. Start the blower, and the inside of the cloth taking cylinder is under negative pressure. The leakage hole will then generate suction to adsorb the upper layer of cloth to be tested, drive the distribution tube to slide upward, and drive the two cloth taking cylinders to move upward along the first limit groove. With the help of the rotating mechanism, the cloth taking cylinders will rotate during the upward movement, and the edge of the cloth will be wrapped around the cloth taking cylinder.

[0028] c. As the fabric taking cylinder continues to move upward and enters the second limiting groove, the second limiting groove, which forms an outward-expanding structure, drives the fabric taking cylinder to move to both sides, so that the fabric is in a taut state.

[0029] d. During the movement of the cloth taking tube in the second limiting groove, the baffle tube contacts the upper push plate, pushing the baffle tube to move downward, switching the conduction pipeline of the three-way pipe, so that the cloth taking tube is no longer in a negative pressure state, while the dust suction nozzle is in a negative pressure state, and the cloth debris generated during the detection is collected through the dust suction nozzle.

[0030] e. Drive the pressure ball to slide and perform strength testing on the fabric;

[0031] f. After the test is completed, the drive distribution tube slides down to reset, causing the cloth taking cylinder to move down and rotate in the opposite direction, so that the cloth automatically separates from the cloth taking cylinder. The staff cleans up the fallen cloth. When the baffle tube contacts the push plate on the lower side, the baffle tube moves up again to switch the conduction pipeline of the three-way pipe, so that suction is generated at the leakage hole again.

[0032] 3. Beneficial effects

[0033] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0034] 1. The technical solution of this application, by setting up a fabric picking cylinder, a blower and a lifting mechanism, can automatically pick up the fabric when testing large batches of fabric, without the need for staff to manually clamp and fix the fabric, which effectively improves the efficiency of testing the strength of the fabric.

[0035] 2. The technical solution of this application, by setting up an unfolding mechanism, can pull the fabric to both sides before testing, so that the fabric to be tested is in a taut state, thereby ensuring the accuracy of the fabric strength test.

[0036] 3. The technical solution of this application, by setting rack and gear, will rotate when the cloth taking tube moves the cloth upward, and will wind the cloth. This can fix the cloth more firmly and tighten the cloth further, effectively ensuring the accuracy of the test results.

[0037] 4. The technical solution of this application sets up a three-way pipe, a baffle pipe and a push plate. When the fabric picking cylinder moves upward to the highest point with the fabric, the baffle pipe will block the distribution pipe, so that the fabric picking cylinder is no longer in a negative pressure state. After the test is completed, when the fabric picking cylinder carries the fabric through the rack, the fabric picking cylinder reverses and will automatically drop the tested fabric, without the need for the staff to manually remove the fabric, which further improves the testing efficiency of the fabric.

[0038] 5. The technical solution of this application, by setting up a suction nozzle, a receiving box and a filter, ensures that when the baffle moves to the lower side and the pressure ball performs strength testing on the fabric, the suction nozzle will absorb the scattered fine fabric fragments during the testing process and collect them in the receiving box, effectively ensuring the cleanliness of the testing environment.

[0047] The present application will be further described in detail below with reference to the accompanying drawings.

[0048] Reference Figures 1 to 3This application discloses a fabric strength testing device, including a housing 1. A cylinder 27 is fixedly installed on the housing 1. A pressure sensor 23 is installed at the lower end of the cylinder 27. A pressure ball 14 is fixedly installed on the pressure sensor 23. A fabric placement assembly 8 is also installed inside the housing 1. The fabric placement assembly 8 includes a storage box 801 fixedly installed inside the housing 1. A placement rack 802 for placing fabric is installed inside the storage box 801. A distribution pipe 17 is also installed inside the housing 1. Two fabric picking cylinders 6 are installed on one side of the distribution pipe 17. The fabric picking cylinders 6 are densely covered with perforations 601. The fabric picking cylinders 6 are connected to the inner cavity of the distribution pipe 17. A blower 11 is also fixedly installed on one side of the housing 1. A receiving hose 4 is installed on one side of the suction end of the blower 11. The other end of the receiving hose 4 is connected to the inner cavity of the distribution pipe 17. A lifting mechanism is also installed inside the housing 1. The lifting mechanism can drive the fabric picking cylinders 6 to move up and down.

[0049] The lifting mechanism includes several electric push rods 12 fixedly installed inside the housing 1, a limiting tube 16 fixedly connected to one side of the fabric picking cylinder 6, and two receiving plates 3 fixedly installed inside the housing 1. The distribution tube 17 is fixedly connected to the output end of the electric push rods 12. A driving plate 2 is fixedly provided on one side of the distribution tube 17. Two driving grooves 201 are opened on the driving plate 2. The two driving grooves 201 are arranged in a symmetrical structure. A first limiting groove 301 is opened on the receiving plate 3. The first limiting groove 301 is arranged in a longitudinal structure to fully ensure that the limiting tube 16 can drive the fabric picking cylinder 6 and the fabric to move upward. The limiting tube 16 is simultaneously slidably connected to the corresponding driving groove 201 and the first limiting groove 301 and rotates therein.

[0050] Under the action of the blower 11, the fabric taking cylinder 6 is in a negative pressure state, and the leakage hole 601 immediately generates suction to adsorb the fabric to be tested. Under the action of the electric push rod 12, the plate 2 drives the limiting tube 16 and the fabric taking cylinder 6 to move upward along the first limiting groove 301. The fabric taking cylinder 6 carries the fabric to be tested upward a certain distance, and the cylinder 27 pushes the pressure ball 14 to test the strength of the fabric. This method does not require the staff to frequently manually clamp the fabric, which greatly improves the efficiency of fabric strength testing.

[0051] Reference Figure 3 and Figure 4 A rotating mechanism is also installed on one side of the distribution tube 17. The rotating mechanism can drive the cloth taking tube 6 to rotate. The rotating mechanism includes a gear 20 sleeved on the limiting tube 16 and two racks 19 fixedly installed on the receiving plate 3. Due to the setting of the gear 20 and the racks 19, the cloth taking tube 6 can wrap the cloth around the outside of the cloth taking tube 6 to further fix the cloth to be tested. The gear 20 is meshed with the corresponding rack 19.

[0052] A limiting mechanism is also installed on the receiving plate 3. The limiting mechanism includes a toothed plate 28 that is slidably connected to the receiving plate 3. Several elastic elements 29 are fixedly connected between the toothed plate 28 and the receiving plate 3. The gear 20 is engaged with the toothed plate 28.

[0053] When the distribution tube 17 rises to the point where the gear 20 meshes with the rack 19, the gear 20 will drive the limiting tube 16 and the fabric taking tube 6 to rotate, so that the edge of the fabric is wrapped around the fabric taking tube 6. On the one hand, this can fix the fabric more firmly, and on the other hand, it can further tighten the fabric. When the gear rises to the highest point, the toothed plate 28 will come into close contact with the gear 20 to limit the gear 20, preventing the fabric taking tube 6 from rotating randomly, which is conducive to the smooth progress of strength testing.

[0054] Furthermore, an inclined groove is provided on the receiving plate 3, which is connected to the lower side of the first limiting groove 301 (not shown in the figure). The limiting tube 16 slides and rotates in the corresponding driving groove 201 and the inclined groove. The shape of the rack 19 matches the structure of the first limiting groove 301 and the inclined groove. The distribution tube 17 is pushed upward by the electric push rod 12, so that the driving plate 2 moves upward synchronously. Under the combined action of the inclined groove and the driving groove 201, the limiting tube 16 is pushed upward and moves towards the middle of the driving plate 2, so that the cloth taking tube 6 can move from both ends of the cloth to the middle and wrap the cloth around the cloth taking tube 6, so that the cloth is wrapped and fixed more firmly and flat.

[0055] Reference Figures 2 to 4 A connecting hose 18 is fixedly connected between the inner cavity of the limiting tube 16 and the distribution tube 17. An unfolding mechanism is also installed on one side of the distribution tube 17. The unfolding mechanism can drive the fabric taking cylinders 6 on both sides to move in a straight line in opposite directions. The unfolding mechanism includes a second limiting groove 302 opened on the receiving plate 3. The second limiting groove 302 is set with an inclined structure. After the limiting tube 16 enters the second limiting groove 302, the limiting tube 16 will drive the corresponding fabric taking cylinder 6 to move to both sides, so that the fabric gradually unfolds and tightens. The second limiting groove 302 is connected to the upper side of the first limiting groove 301. The limiting tube 16 is slidably connected to the corresponding second limiting groove 302.

[0056] When the driving plate 2 moves the limiting tube 16 and the cloth taking tube 6 along the first limiting groove 301 to the second limiting groove 302, the limiting tube 16 then moves the cloth taking tube 6 along the second limiting groove 302 and moves the cloth taking tube 6 to both sides. The cloth taking tube 6 will lift the cloth and unfold it to both sides at the same time, so that the cloth is in a taut state, ensuring the accuracy of the test results.

[0057] It should be noted that the inclined groove and the second limiting groove 302 are opened on the same side of the first limiting groove 301, and the two are opened in opposite inclination directions, so that the fabric taking tube 6 can roll and wrap the fabric inward, and then pull the fabric outward to tighten it.

[0058] In the above embodiments, such as Figure 4 As shown, when the fabric taking cylinder 6 slides along the second limiting groove 302 to tighten the fabric, the reaction force of the fabric may cause the fabric taking cylinder 6 to reverse, thereby causing the fabric to slide in the opposite direction on the fabric taking cylinder 6 to unwind part or even completely, making it difficult to effectively achieve the effect of fixing and tightening the fabric. For this reason, a locking extension strip (not shown in the figure) is fixed on the upper side of the rack 19, and the shape of the locking extension strip matches the second limiting groove 302. A limiting groove is fixed on one side of the locking extension strip, and multiple sliders are fixed on the outer side of the rotating shaft of the gear 20. The sliders can slide along the limiting groove. During the process of the fabric taking cylinder 6 sliding along the second limiting groove 302, one of the sliders slides into the limiting groove to position the slider and the gear 20. The slider will not disengage from the limiting groove during the process of sliding in the limiting groove, but can only slide in or out from both ends of the limiting groove, so that the fabric taking cylinder 6 will not reverse when pulling the fabric outward to tighten it, and the fabric tightening is stable and reliable.

[0059] Reference Figure 1 , Figure 5 and Figure 6 A three-way pipe 5 is fixedly connected between the distribution pipe 17 and the other end of the receiving hose 4. A baffle pipe 7 is installed inside the three-way pipe 5. The baffle pipe 7 is in frictional contact with the three-way pipe 5. A vent 701 is opened on one side of the baffle pipe 7. Two push plates 22 are fixedly installed on the upper and lower sides inside the housing 1. The push plates 22 are in movable contact with the baffle pipe 7.

[0060] A limiting cylinder 9 is fixedly installed on the distribution pipe 17. A connecting rod 10 is slidably connected inside the limiting cylinder 9. Several mounting grooves 1001 are opened on the connecting rod 10. A limiting ball block 13 is slidably connected inside the mounting groove 1001. A spring 15 is fixedly connected between the limiting ball block 13 and the mounting groove 1001. The purpose of setting the spring 15 is to reset the limiting ball block 13. Several limiting grooves 901 adapted to the limiting ball block 13 are opened inside the limiting cylinder 9. The limiting ball block 13 and the limiting groove 901 are in frictional contact.

[0061] The other end of the baffle pipe 7 is fixedly connected to a dust suction nozzle 21. The suction end of the blower 11 is fixedly connected to the end of the receiving hose 4 and a receiving box 25 is fixedly connected. A sealing cover 24 is inserted into the receiving box 25 and a filter screen 26 is fixedly installed inside the receiving box 25.

[0062] When the distribution pipe 17 moves upward and the baffle pipe 7 contacts the upper push plate 22, the baffle pipe 7 moves downward under the action of the push plate 22, blocking one side of the three-way pipe 5. That is, the baffle pipe 7 blocks the distribution pipe 17. At this time, the cloth taking cylinder 6 is no longer in a negative pressure state, and the ventilation port 701 opened on the baffle pipe 7 enters the interior of the three-way pipe 5, opening the baffle pipe 7. The dust nozzle 21 is then in a negative pressure state, and the cloth debris generated during the test enters the receiving box 25 through the dust suction nozzle 21 for collection, fully ensuring the cleanliness of the testing environment. When the baffle pipe 7 moves downward, the gear 20 meshes with the rack 19 again, and the cloth taking cylinder 6 reverses, so that the cloth on the cloth taking cylinder 6 automatically disengages from the cloth taking cylinder 6, eliminating the need for staff to manually remove the cloth, further improving the efficiency of cloth strength testing. The flow path of the three-way pipe 5 can be switched by sliding the baffle 7 up and down, and different functions can be achieved at different times according to the needs. During the movement of the baffle 7, the setting of the limiting ball block 13, the limiting groove 901 and the spring 15 can increase the friction and prevent the baffle 7 from moving randomly.

[0063] Reference Figure 1 and Figure 7 The placement rack 802 is constrained by and slidably connected to the storage box 801. The fabric placement assembly 8 also includes several rotating racks 804 fixedly installed on both sides of the storage box 801 and two counterweights 806 slidably connected to both sides of the storage box 801. Rollers 805 are rotatably connected to the rotating racks 804, and several connecting ropes 803 are fixedly connected to the counterweights 806. Due to the setting of the counterweights 806 and connecting ropes 803, as the amount of fabric decreases, the placement rack 802 will drive the fabric to gradually move upward, so that the uppermost fabric is always in the same position, which is convenient for the fabric taking tube 6 to take the fabric. The other end of the connecting rope 803 passes around the corresponding roller 805 and is connected and fixed to the placement rack 802.

[0064] The staff neatly stacks a specified number of fabrics on the placement rack 802. As the amount of fabric decreases, the placement rack 802 gradually moves the fabrics upward under the action of the counterweight 806, so that the uppermost fabric is always in the same position, making it convenient for the fabric retrieval tube 6 to retrieve the fabric.

[0065] The principle of the fabric strength testing device in this application embodiment is as follows: When relevant personnel need to conduct strength testing on a large batch of fabrics, the personnel first place the fabric to be tested on the placement rack 802. Under the action of the fabric's gravity, the counterweight 806 moves upward and the placement rack 802 moves downward.

[0066] Then, under the action of the blower 11, the fabric taking cylinder 6 is in a negative pressure state, and suction is generated at the leakage hole 601 to adsorb the fabric to be tested. Under the action of the electric push rod 12, the drive plate 2 drives the limiting tube 16 and the fabric taking cylinder 6 to move upward along the first limiting groove 301.

[0067] When gear 20 contacts rack 19, gear 20 meshes with rack 19, thus driving limit tube 16 and fabric taking tube 6 to rotate, causing the edge of fabric to wrap around fabric taking tube 6.

[0068] As the drive plate 2 continues to move upward, when the limiting tube 16 and the cloth taking tube 6 move along the first limiting groove 301 to the second limiting groove 302, the limiting tube 16 then drives the cloth taking tube 6 to move along the second limiting groove 302, and drives the cloth taking tube 6 to move to both sides, so that the cloth is in a taut state.

[0069] During this process, the baffle 7 comes into contact with the upper push plate 22. Under the action of the thrust, the baffle 7 moves downward and blocks one side of the three-way pipe 5. At this time, the cloth take-off cylinder 6 is no longer in a negative pressure state.

[0070] At the same time, the suction nozzle 21 is immediately under negative pressure, and the fabric debris generated during the test is collected in the receiving box 25 through the suction nozzle 21, thus ensuring the cleanliness of the testing environment.

[0071] Subsequently, under the action of cylinder 27, pressure ball 14 immediately performs strength testing on the fabric.

[0072] After the test is completed, the electric push rod 12 drives the plate 2 to reset the limit tube 16. When the gear 20 meshes with the rack 19 again, the fabric taking cylinder 6 will reverse. Since the fabric taking cylinder 6 is no longer under negative pressure, the fabric on the fabric taking cylinder 6 will automatically detach from the cylinder, and the staff will clean up the fallen fabric. When the baffle 7 contacts the push plate 22 on the lower side, the baffle 7 moves upward, and suction is generated again at the leakage hole 601. This process is repeated to complete the strength test of a large batch of fabric.

A connecting rope is fixedly connected between the counterweights and the placement rack.

8. The method of using the fabric strength testing device according to any one of claims 4-7, characterized in that, Includes the following steps: a. Place the fabric to be tested on the rack. Under the weight of the fabric, the rack moves downward and the counterweight moves upward. b. Start the blower, and the inside of the cloth taking cylinder is under negative pressure. The leakage hole will then generate suction to adsorb the upper layer of cloth to be tested, drive the distribution tube to slide upward, and drive the two cloth taking cylinders to move upward along the first limit groove. With the help of the rotating mechanism, the cloth taking cylinders will rotate during the upward movement, and the edge of the cloth will be wrapped around the cloth taking cylinder. c. As the fabric taking cylinder continues to move upward and enters the second limiting groove, the second limiting groove, which forms an outward-expanding structure, drives the fabric taking cylinder to move to both sides, so that the fabric is in a taut state. d. During the movement of the cloth taking tube in the second limiting groove, the baffle tube contacts the upper push plate, pushing the baffle tube to move downward, switching the conduction pipeline of the three-way pipe, so that the cloth taking tube is no longer in a negative pressure state, while the dust suction nozzle is in a negative pressure state, and the cloth debris generated during the detection is collected through the dust suction nozzle. e. Drive the pressure ball to slide and perform strength testing on the fabric; f. After the test is completed, the drive distribution tube slides down to reset, causing the cloth taking cylinder to move down and rotate in the opposite direction, so that the cloth automatically separates from the cloth taking cylinder. The staff cleans up the fallen cloth. When the baffle tube contacts the push plate on the lower side, the baffle tube moves up again to switch the conduction pipeline of the three-way pipe, so that suction is generated at the leakage hole again.
