Description

Technical Field

[0001] This invention relates to the field of sewing thread testing equipment technology, specifically to a polytetrafluoroethylene (PTFE) sewing thread production testing equipment. Background Technology

[0002] Polytetrafluoroethylene (PTFE) sewing thread is resistant to strong acids and alkalis and has excellent chemical stability. It also has advantages such as high tensile strength and good abrasion resistance, making it suitable for sewing high-temperature resistant products. It can be used in the production of outdoor products such as outdoor tents, sailboats, and mountaineering clothing.

[0003] When using PTFE sewing thread production and testing equipment to perform tensile testing on PTFE sewing thread, the sewing thread needs to be fixed vertically on the equipment first, and then the sewing thread is tested by pulling the equipment up and down. However, each time the sewing thread is tested, it needs to be fixed again, which is not only time-consuming and labor-intensive, but also affects work efficiency. In view of the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a polytetrafluoroethylene sewing thread production and testing equipment, including a machine casing, and a control box is fixedly connected to the outer wall of the machine casing; The control mechanism has internal installation space, which can be used to install fixed equipment and maintain the normal operation of the equipment; An automatic line changing mechanism is installed on the outer wall of the control mechanism. It can be used to control automatic line changing during testing, thereby improving work efficiency. The cleaning and cutting mechanism is installed on the inner wall of the automatic thread changing mechanism. It can be used to cut and remove excess thread to prevent jamming.

[0005] Preferably, the control mechanism includes: The housing assembly is installed on the outer wall of the control mechanism through housing parts, and the housing assembly can provide a certain degree of protection for the equipment. The outer casing includes a fixing ring block fixedly connected to the top of the chassis. A sewing thread is slidably connected to the inner wall of the fixing ring block. After the sewing thread is placed in the chassis, it passes through the fixing ring block, which allows the sewing thread to move smoothly and avoids misalignment during movement. The power component has its outer wall slidably connected to the outer wall of the housing component. Through the power component, the necessary power source can be provided for the overall equipment during operation.

[0006] Preferably, the automatic line changing mechanism includes: The upper adjustment component is fixedly connected to the outer wall of the power component via an upper adjustment piece. The upper adjustment component can be used to clamp and adjust one end of the sewing thread for subsequent tensile testing. The upper adjustment component includes a roller slider slidably connected to the inner wall of the adjustment block one, an inclined protrusion fixedly connected to the outer wall of the outer casing, an air pressure pipe one fixedly connected to the inner wall of the adjustment block one, the outer wall of the air pressure pipe one fixedly connected to the inner wall of the fixed block one, an inclined slider slidably connected to the inner wall of the outer casing, and an air pressure pipe two fixedly connected to the inner wall of the outer casing. After moving to the position where the roller slider contacts the inclined protrusion, the roller slider will be pressed inward, and the gas on its side will enter the fixed block one through the air pressure pipe one, pushing the spring block one to further clamp the sewing thread and maintain a strong clamping force. At the same time, the inclined slider will also contact the adjustment block one, and the gas on its side will enter the fixed block one through the air pressure pipe two, pushing the spring block three to clamp the bottom of the sewing thread. The lower adjustment component is fixedly connected to the outer wall of the housing component via a lower adjustment piece. The lower adjustment component can be used to clamp and adjust one end of the sewing thread for subsequent tensile testing. The lower adjustment component includes a spring block three that is slidably connected to the inner wall of the lower base. A retaining strip is fixedly connected to the outer wall of the spring block three. The outer wall of the retaining strip is slidably connected to the inner wall of the lower base. After the sliding block reaches the top, the fixed block one continues to move downward, which will squeeze the spring block two to move downward. After the spring block two moves to the bottom, the retaining strip will be locked in the groove of the spring block two by the action of the spring block three, thereby restricting the movement of the spring block two. When the fixed block one moves upward, the spring block two cannot move because it is locked.

[0007] Preferably, the cleaning and cutting mechanism includes: The jet assembly is fixedly connected to the inner wall of the lower adjustment assembly via a jet component. The jet assembly can blow away any fallen sewing thread. The jet component includes an air outlet on the top of the pressure box. When the gas flows upward, it can be ejected outward through the air outlet. Since the first spring block retracts inward when it descends, the ejected gas can directly act on the side of the first spring block when it approaches the lower base. The cutting assembly is fixedly connected to the outer wall of the lower adjusting assembly via a cutting piece. The cutting assembly can be used to cut broken sewing threads, allowing for better clamping later. The shearing component includes a fixing strip fixedly connected to the outer wall of the fixing block two, an adjusting block two slidably connected to the inner wall of the spring telescopic tube, a spring block four slidably connected to the inner wall of the spring telescopic tube, the top of the spring block four slidably connected to the bottom of the adjusting block two, and a cutting blade fixedly connected to the outer wall of the spring telescopic tube. When the piston plate moves downward, it will compress the gas at its bottom, causing the gas to enter the spring telescopic tube through the air pressure pipe four. At this time, under the action of the adjusting block two, the spring block four and the head of the spring telescopic tube are in a closed state. After the gas enters the spring telescopic tube, it will extend outward and drive the cutting blade to move synchronously to cut the sewing thread.

[0008] Preferably, the housing assembly includes a housing cover fixedly connected to the top of the chassis, and a telescopic curtain is slidably connected to the inner wall of the housing cover. By setting the housing cover and the telescopic curtain, the internal components can be kept isolated from the outside, preventing broken sewing threads from entering and causing the equipment to get stuck, thus affecting the normal operation of the equipment.

[0009] Preferably, the power assembly includes a motor fixedly connected to the inner wall of the chassis, a threaded column fixedly connected to the top of the motor, the outer wall of the threaded column being rotatably connected to the inner wall of the chassis, a fixed slide rod fixedly connected to the top of the chassis, and an adjusting block 1 slidably connected to the outer wall of the fixed slide rod. The inner wall of the adjusting block 1 is engaged with the outer wall of the threaded column. When the motor is powered on, it can synchronously drive the threaded column to rotate. When the threaded column rotates, it drives the adjusting block 1 to move. When the motor rotates clockwise, it will cause the adjusting block 1 to move upward, and when the motor rotates counterclockwise, it will cause the adjusting block 1 to move downward.

[0010] Preferably, the upper adjustment assembly includes a sensor fixedly connected to the bottom of the adjustment block one, a fixed block one fixedly connected to the bottom of the sensor, a sliding block slidably connected to the inner wall of the fixed block one, and a spring block one slidably connected to the inner wall of the fixed block one. Utilizing the characteristic that the threaded column can drive the adjustment block one to move up and down when rotating, a fixed block one is provided. When the motor is energized, it synchronously drives the threaded column to rotate. When the threaded column rotates, it can drive the adjustment block one to move up and down. When the adjustment block one moves downward, the sensor drives the fixed block one to move downward. When the fixed block one moves downward, it causes the sliding block and spring block one to... When the top of block two contacts the sliding block, the sliding block will be pressed upwards. As the sliding block moves upwards, it creates a negative pressure inside the fixed block one, causing the spring block one to contract inwards. The spring blocks one at both ends open together. After the sliding block reaches the top, the fixed block one continues to move downwards, squeezing the spring block two downwards. After the spring block two reaches the bottom, the action of the spring block three causes the locking strip to lock into the groove of the spring block two, thus restricting the movement of the spring block two. When the fixed block one moves upwards, the spring block two cannot move because it is locked. At this time, the action of the spring block one causes the spring blocks one at both ends to move outwards. The sewing thread is clamped in a clamping state. Then, as the fixing block moves upwards along with the sewing thread, it reaches the position where the roller slider contacts the inclined protrusion. The roller slider is then pressed inwards, and the gas on its side enters the fixing block through the air pressure pipe, pushing the spring block to further clamp the sewing thread, maintaining a strong clamping force. Simultaneously, as the roller slider retracts, the inclined slider also contacts the adjusting block and contracts under pressure, causing the gas on one side to enter the fixing block through the air pressure pipe, pushing the spring block to clamp the bottom of the sewing thread. The three-phase movement synchronously drives the locking strip to move, causing it to disengage from the groove of spring block two. Then, spring block two returns to its original position through rebound. After clamping both ends, the movement continues to perform a tensile test on the sewing thread until it breaks. The control box generates a data report for this section of the sewing thread. Then, fixed block one will continue to descend to perform the next tensile test. This process repeats, allowing the equipment to automatically perform tensile tests on multiple sections of the sewing thread after it is clamped in the lower base. This avoids the need to clamp both ends of the sewing thread for each test, which is not only time-consuming and labor-intensive but also affects its working efficiency.

[0011] Preferably, the lower adjustment assembly includes a lower base fixedly connected to the top of the chassis. A spring slider is slidably connected to the inner wall of the lower base, and a roller is rotatably connected to the inner wall of the spring slider. A second spring block is slidably connected to the inner wall of the lower base. Using the above-described method, after the sewing thread breaks, the fixed block can continue to descend for the next test. As the fixed block continues to descend, it will cause the sliding block to contact the second spring block, causing the sliding block to move upward under pressure. This upward movement creates a negative pressure in the fixed block, causing the first spring block to contract inward. After both spring blocks contract inward, the distance between them will increase. The broken sewing thread will fall downward as it is no longer subject to clamping force after the two spring blocks move away from each other. When the sliding block contacts and presses against the second spring block, the sliding block will... First, the mechanism moves upwards. This causes the broken sewing thread to fall downwards when the fixing block is still some distance from the lower base. Through the operation of the above components, the broken sewing thread will automatically fall downwards when the fixing block is a certain distance from the lower base. This avoids the inconvenience of manual adjustment required when the broken sewing thread is clamped, and also prevents the broken sewing thread from contacting the lower base when the distance is too close, thus avoiding it from falling downwards and remaining at the clamping point of the spring block, which would affect the subsequent clamping of the sewing thread. In addition, the spring slider and roller can clamp the sewing thread to a certain extent without affecting its movement, so that the sewing thread will always maintain a certain tension when pulled upwards, avoiding the problem of the sewing thread becoming loose when pulled, which would affect the subsequent tension detection of the sewing thread.

[0012] Preferably, the jet assembly includes a pressure pipe three fixedly connected to the inner wall of the lower base, a pressure box fixedly connected to the inner wall of the lower base, and the inner wall of the pressure box fixedly connected to the outer wall of the pressure pipe three. A conical groove and an air outlet groove are formed on the inner wall of the pressure box. Utilizing the characteristic that the spring block two moves up and down as described above, a pressure box is provided. When the spring block two moves downwards, it compresses the gas at its bottom, causing it to enter the pressure box through the pressure pipe three. After entering the pressure box, due to the characteristics of the conical groove, as the gas flows upwards, the space at the top becomes increasingly smaller, and the air pressure is gradually compressed and increased. Then, the gas is ejected outwards through the air outlet groove. The gas blows away any fallen sewing thread from the top of the lower base, preventing it from getting tangled in subsequent sewing threads and affecting the pulling and testing of those threads, thus causing deviations in the test results. Additionally, as the gas flows upward, it is also expelled through the vent. Because spring block one contracts inward as it descends, the expelled gas directly acts on the side of spring block one when it approaches the lower base. This prevents the sewing thread from deforming and sticking to the side of spring block one during the tensile test due to the large clamping force, which would affect the clamping of the sewing thread in the next round of testing and thus impact the test results.

[0013] Preferably, the shearing assembly includes a piston plate fixedly connected to the outer wall of the second spring block. The outer wall of the piston plate is slidably connected to the inner wall of the lower base. A pneumatic tube four is fixedly connected to the inner wall of the lower base. A fixing block two is fixedly connected to the top of the lower base. A spring telescopic tube is fixedly connected to the inner wall of the fixing block two. The inner wall of the spring telescopic tube is fixedly connected to the outer wall of the pneumatic tube four. Utilizing the characteristic that the second spring block moves up and down under pressure, a piston plate is provided. When the second spring block moves downward, it synchronously drives the piston plate downward. During downward movement, it compresses the gas at its bottom, causing the gas to enter the spring telescopic tube through the pneumatic tube four. At this time, under the action of the adjusting block two, the head of the fourth spring block and the spring telescopic tube are in a closed state. After the gas enters the spring telescopic tube, it extends outward, driving the cutting blade to move synchronously to cut the sewing thread. When the spring telescopic tube extends outward, it interacts with another… When the four spring blocks at both ends come into contact and are compressed, they will contract inward. At this time, the adjusting block two will be locked into another groove of the spring block four. The groove at the bottom of the spring block four will allow the inside of the spring telescopic tube to communicate with the outside, allowing the gas entering the spring telescopic tube to flow outward through the groove at the bottom of the spring block four. After the air intake stops, the spring telescopic tube will begin to contract under the action of the spring inside the spring telescopic tube, and the spring block four will come into contact with the fixing strip, allowing the spring block four to reset. The adjusting block two will then be locked back into the previous groove of the spring block four, and the top of the spring telescopic tube will close again. Through the operation of the above components, the sewing thread can be cut by the cutting blade when the spring telescopic tube extends outward, avoiding the situation where the break point is close to the fixing block one, leaving too much sewing thread at the bottom. In this case, the sewing thread will be bent downward under pressure, which will affect the subsequent clamping.

[0014] The present invention has the following beneficial effects: (1) This invention utilizes the characteristic that the threaded column can drive the adjusting block 1 to move up and down when it rotates. A fixed block 1 is set up. The fixed block 1 moves so that the sliding block contacts the spring block 2. The sliding block moves under pressure, causing the spring block 1 to contract. The fixed block 1 moves and, under the action of the spring block 1, the spring block 1 clamps the sewing thread. As the fixed block 1 moves, after the roller slider contacts the inclined protrusion, the roller slider will push the spring block 1 to clamp the sewing thread. At the same time, the inclined slider contacts the adjusting block 1 and allows gas to enter the fixed block 1 through the air pressure pipe 2, pushing the spring block 3 to clamp the bottom of the sewing thread. After clamping at both ends, the movement will perform a tensile test on the sewing thread, realizing automatic tensile testing of multiple sections of the sewing thread. This avoids the need to clamp the upper and lower ends of the sewing thread every time it is tested, which is not only time-consuming and laborious, but also affects its working efficiency.

[0015] (2) As mentioned above, when the fixed block one continues to descend after the sewing thread breaks, the sliding block contacts the spring block two. The sliding block is pressed and moves upward. The upward movement of the sliding block causes the spring block one to contract. After the spring blocks one at both ends contract, the distance in the middle will be expanded. The broken sewing thread will fall downward after the spring blocks one at both ends move away. This realizes that the broken sewing thread can fall downward automatically, avoiding the trouble of manual adjustment each time. In addition, the spring slider and roller can keep the sewing thread under a certain tension without affecting the movement of the sewing thread, avoiding the problem of the sewing thread becoming loose when pulled, thus affecting the subsequent tensile strength detection of the sewing thread.

[0016] (3) The present invention utilizes the characteristic of the second spring block moving up and down as mentioned above to set up a pressure box. The second spring block moves down and squeezes the gas at its bottom, so that it enters the pressure box through the third pressure pipe. Due to the characteristics of the conical groove, as the gas flows upward, the space at the top becomes smaller and smaller, and the air pressure is gradually compressed and increased. It is sprayed out through the air outlet to blow the fallen sewing thread to one side, so as to avoid the fallen sewing thread from getting tangled in the subsequent sewing thread, which would affect the subsequent pulling and detection of the sewing thread. In addition, the gas will also be sprayed out through the air outlet to directly act on the side of the first spring block, so as to avoid the sewing thread from deforming during the clamping process and sticking to the side of the first spring block, which would affect the clamping of the sewing thread and thus cause errors in the detection results.

[0017] (4) This invention utilizes the characteristic that the second spring block moves up and down when subjected to pressure. A piston plate is set up. The second spring block moves down, causing the piston plate to move down and squeezing the gas at its bottom. This gas is then passed through the fourth air pressure pipe and enters the spring telescopic tube. At this time, the fourth spring block and the head of the spring telescopic tube are closed. After the gas enters the spring telescopic tube, it will extend outward and drive the cutting blade to move synchronously to cut the sewing thread. The extended spring telescopic tube will squeeze the fourth spring block at the other end, causing the fourth spring block to contract inward. At this time, the second adjusting block will be stuck in another groove of the fourth spring block, allowing the inside of the spring telescopic tube to communicate with the outside. The gas entering the spring telescopic tube will flow outward. After the air intake stops, the fourth spring block will contact the fixing strip due to the action of the spring telescopic tube, allowing the fourth spring block to reset. The second adjusting block will then be stuck back in the first groove of the fourth spring block, and the head of the spring telescopic tube will close. Through the operation of the above components, the sewing thread is cut by the cutting blade when the spring telescopic tube extends, avoiding the sewing thread from bending downward due to pressure because the break is close to the first fixing block, which would affect the subsequent clamping.

The cleaning and cutting mechanism 3 is installed on the inner wall of the automatic thread changing mechanism 2. It can be used to cut and remove excess thread to prevent jamming.

[0023] Control mechanism 1 includes: The housing assembly 11 is mounted and connected to the outer wall of the control mechanism 1 via housing parts. The housing assembly 11 can provide a certain degree of protection for the equipment. The outer casing includes a fixing ring 115 fixedly connected to the top of the chassis 111. A sewing thread 116 is slidably connected to the inner wall of the fixing ring 115. After the sewing thread 116 is placed into the chassis 111, it passes through the fixing ring 115, which can make the sewing thread 116 move smoothly and avoid misalignment during movement. The power assembly 12 has its outer wall slidably connected to the outer wall of the housing assembly 11. The power assembly 12 can provide the necessary power source for the entire equipment during operation.

[0024] The automatic line changing mechanism 2 includes: The upper adjustment component 21 is fixedly connected to the outer wall of the power component 12 via an upper adjustment piece. The upper adjustment component 21 can clamp and adjust one end of the sewing thread 116 for subsequent tensile testing. The upper adjustment component includes a roller slider 215 slidably connected to the inner wall of the adjusting block 124; a beveled protrusion 216 fixedly connected to the outer wall of the outer casing 113; a pneumatic pipe 217 fixedly connected to the inner wall of the adjusting block 124; the outer wall of the pneumatic pipe 217 fixedly connected to the inner wall of the fixed block 212; a beveled slider 218 slidably connected to the inner wall of the outer casing 113; and a pneumatic pipe 219 fixedly connected to the inner wall of the outer casing 113. When the roller slider 215 moves to the beveled slider 218, the upper adjustment component... After the protrusion 216 contacts the position, the roller slider 215 will be pressed inward, and the gas on its side will enter the fixed block 212 through the air pressure pipe 217, and push the spring block 214 to further clamp the sewing thread 116, maintaining a strong clamping force. At the same time, the inclined slider 218 will also contact the adjusting block 124, and the gas on its side will enter the fixed block 212 through the air pressure pipe 219, pushing the spring block 225 to clamp the bottom of the sewing thread 116.

The lower adjustment component includes a spring block 225 slidably connected to the inner wall of the lower base 221. A retaining strip 226 is fixedly connected to the outer wall of the spring block 225. The outer wall of the retaining strip 226 is slidably connected to the inner wall of the lower base 221. After the sliding block 213 reaches the top, the fixed block 212 continues to move downward, which will squeeze the spring block 224 to move downward. After the spring block 224 moves to the bottom, the retaining strip 226 will be stuck in the groove of the spring block 224 due to the action of the spring block 225, thereby restricting the movement of the spring block 224. When the fixed block 212 moves upward, the spring block 224 cannot move because it is stuck.

[0025] Cleaning and cutting mechanism 3 includes: The jet assembly 31 is fixedly connected to the inner wall of the lower adjustment assembly 22 via a jet component. The jet assembly 31 can blow away the fallen sewing thread 116. The jet component includes an air outlet 315 on the top of the pressure box 312. When the gas flows upward, it can be ejected outward through the air outlet 315. Since the spring block 214 contracts inward when it descends, the ejected gas can directly act on the side of the spring block 214 when it approaches the lower base 221. The cutting component 32 is fixedly connected to the outer wall of the lower adjusting component 22 via a cutting piece. The cutting component 32 can be used to cut the broken sewing thread 116 so that it can be better clamped later.

When the piston plate 321 moves downward, it will compress the gas at its bottom, causing the gas to enter the spring telescopic tube 324 through the air pressure pipe 4 322. At this time, under the action of the adjusting block 2 326, the spring block 4 327 and the head of the spring telescopic tube 324 are in a closed state. After the gas enters the spring telescopic tube 324, it will extend outward and drive the cutting blade 328 to move synchronously to cut the sewing thread 116.

[0026] The outer casing assembly 11 includes an outer casing cover 113 fixedly connected to the top of the chassis 111. A telescopic curtain 114 is slidably connected to the inner wall of the outer casing cover 113. By setting the outer casing cover 113 and the telescopic curtain 114, the internal components can maintain a certain isolation effect from the outside world, preventing some broken sewing threads 116 from entering and causing the equipment to get stuck, thereby affecting the normal operation of the equipment.

[0027] The power assembly 12 includes a motor 121 fixedly connected to the inner wall of the housing 111. A threaded column 122 is fixedly connected to the top of the motor 121. The outer wall of the threaded column 122 is rotatably connected to the inner wall of the housing 111. A fixed slide rod 123 is fixedly connected to the top of the housing 111. An adjusting block 124 is slidably connected to the outer wall of the fixed slide rod 123. The inner wall of the adjusting block 124 is engaged with the outer wall of the threaded column 122. When the motor 121 is energized, it can synchronously drive the threaded column 122 to rotate. When the threaded column 122 rotates, it drives the adjusting block 124 to move. When the motor 121 rotates clockwise, it will cause the adjusting block 124 to move upward. When the motor 121 rotates counterclockwise, it will cause the adjusting block 124 to move downward.

[0028] The upper adjustment assembly 21 includes a sensor 211 fixedly connected to the bottom of the adjustment block 124. A fixed block 212 is fixedly connected to the bottom of the sensor 211. A sliding block 213 is slidably connected to the inner wall of the fixed block 212, and a spring block 214 is slidably connected to the inner wall of the fixed block 212. Utilizing the characteristic that the threaded column 122 can drive the adjustment block 124 to move up and down when it rotates, a fixed block 212 is provided. When the motor 121 is energized, it synchronously drives the threaded column 122 to rotate. When the threaded column 122 rotates, it can drive the adjustment block 124 to move up and down. When the adjustment block 124 moves downward, the sensor 211 drives the fixed block 212 to move downward. When the fixed block 212 moves downward, it causes the sliding block 214 to move downward. When the top of the sliding block 213 contacts the top of the second spring block 224, the sliding block 213 will be pressed upward. When the sliding block 213 moves upward, it will create a negative pressure inside the first fixed block 212, causing the first spring block 214 to contract inward. The two ends of the first spring block 214 will open together. After the sliding block 213 reaches the top, the first fixed block 212 continues to move downward, which will squeeze the second spring block 224 downward. After the second spring block 224 moves to the bottom, the action of the third spring block 225 will cause the locking strip 226 to be locked in the groove of the second spring block 224, thereby restricting the movement of the second spring block 224. When the first fixed block 212 moves upward, the second spring block 224 cannot move because it is locked. At this time, the action of the first spring block 214 will cause the two ends of the first spring block 214 to open together. Spring block 214 will move outward to form a clamping state, holding the sewing thread 116. Then, along with the fixing block 212, it moves upward with the sewing thread 116. After reaching the position where the roller slider 215 contacts the inclined protrusion 216, the roller slider 215 will be pressed inward. The gas on its side will enter the fixing block 212 through the air pressure pipe 217, pushing the spring block 214 to further clamp the sewing thread 116, maintaining a strong clamping force. At the same time, during the retraction of the roller slider 215, the inclined slider 218 will also contact the adjusting block 124 and be compressed during the contact. The gas on its side will enter the fixing block 212 through the air pressure pipe 219, pushing the spring block 225 to clamp the bottom of the sewing thread 116. The device clamps the sewing thread 116, and simultaneously moves the locking strip 226 as the spring block 3 225 moves, causing the locking strip 226 to leave the groove of the spring block 224. Then, the spring block 224 returns to its original position through springback. After clamping at both ends, the device continues to move to perform a tensile test on the sewing thread 116 until the sewing thread 116 breaks. The control box 112 then generates a data report on this section of the sewing thread 116. Then, the fixing block 1 212 continues to descend to perform the next tensile test. This process is repeated, so that after the sewing thread 116 is clamped in the lower base 221, the device can automatically run to perform tensile tests on the sewing thread 116 at multiple positions. This avoids the need to clamp the upper and lower ends of the sewing thread 116 for each test, which is not only time-consuming and labor-intensive but also affects its working efficiency.

[0029] Example 2, please refer to Figures 7-10 This invention relates to a polytetrafluoroethylene (PTFE) sewing thread production and testing device. Based on Embodiment 1, the lower adjustment component 22 includes a lower base 221 fixedly connected to the top of the housing 111. A spring slider 222 is slidably connected to the inner wall of the lower base 221. A roller 223 is rotatably connected to the inner wall of the spring slider 222. A second spring block 224 is slidably connected to the inner wall of the lower base 221. Utilizing the above, after the sewing thread 116 breaks, the first fixing block 212 can continue to descend for the next test. As the fixed block 212 continues to descend, it will cause the sliding block 213 to come into contact with the spring block 224. The sliding block 213 will move upward under pressure. As the sliding block 213 moves upward, a negative pressure will be generated in the fixed block 212. Under the influence of the negative pressure, the spring block 214 will contract inward. After both ends of the spring blocks 214 have contracted inward, the distance between them will be increased. The broken sewing thread 116 will fall downward after the two ends of the spring blocks 214 move away from each other, as it will no longer be subject to the clamping force. When the spring block 224 is pressed, the sliding block 213 will move upward first. This will cause the broken sewing thread 116 to fall downward when the fixed block 212 is still a certain distance away from the lower base 221. Through the operation of the above components, the broken sewing thread 116 will automatically fall downward when the fixed block 212 is a certain distance away from the lower base 221. This avoids the inconvenience of manual adjustment required when the broken sewing thread 116 is clamped, and the risk of breakage when the distance is too close. The sewing thread 116 will contact the lower base 221 and will not fall downwards but will remain at the clamping point of the spring block 214, which would affect the subsequent clamping of the sewing thread 116. In addition, the spring slider 222 and the roller 223 can clamp the sewing thread 116 to a certain extent without affecting its movement, so that the sewing thread 116 will maintain a certain tension when it is pulled upwards, avoiding the problem of the sewing thread 116 becoming loose when pulled, which would affect the subsequent tension detection of the sewing thread 116.

[0030] The jet assembly 31 includes a pneumatic pipe 311 fixedly connected to the inner wall of the lower base 221. A pressure box 312 is fixedly connected to the inner wall of the lower base 221. The inner wall of the pressure box 312 is fixedly connected to the outer wall of the pneumatic pipe 311. A conical groove 313 and an air outlet groove 314 are provided on the inner wall of the pressure box 312. Utilizing the characteristic that the spring block 224 moves up and down as described above, a pressure box 312 is provided. When the spring block 224 moves downward, it compresses the gas at its bottom, causing it to enter the pressure box 312 through the pneumatic pipe 311. After entering the pressure box 312, due to the characteristic of the conical groove 313, the gas pressure gradually increases as it flows upward because the space at the top becomes smaller. Then, it passes through the air outlet groove 314. 14. The gas is sprayed outward to blow the sewing thread 116 that has fallen off the top of the lower base 221 to one side, preventing the fallen sewing thread 116 from getting tangled on subsequent sewing threads 116, which would affect the subsequent pulling and testing of the sewing thread 116 and cause some deviation in the test results. In addition, when the gas flows upward, it will also be sprayed outward through the air outlet 315. Since the spring block 214 will contract inward when it descends, the sprayed gas can directly act on the side of the spring block 214 when it approaches the lower base 221. This prevents the sewing thread 116 from deforming during the clamping process due to the large clamping force in the tensile test and sticking to the side of the spring block 214, which would affect the clamping of the sewing thread 116 in the next round of testing and thus affect the test results.

[0031] The shearing assembly 32 includes a piston plate 321 fixedly connected to the outer wall of the second spring block 224. The outer wall of the piston plate 321 is slidably connected to the inner wall of the lower base 221. A pneumatic pipe 322 is fixedly connected to the inner wall of the lower base 221. A fixing block 323 is fixedly connected to the top of the lower base 221. A spring telescopic tube 324 is fixedly connected to the inner wall of the fixing block 323. The inner wall of the spring telescopic tube 324 is fixedly connected to the outer wall of the pneumatic pipe 322. Utilizing the characteristic that the second spring block 224 moves up and down when subjected to pressure, a... When the second spring block 224 moves downward, the piston plate 321 moves downward in sync with the piston plate 321. As 321 moves downward, it compresses the gas at its bottom, forcing the gas through the fourth air pressure pipe 322 into the spring telescopic tube 324. At this time, under the action of the second adjusting block 326, the fourth spring block 327 and the head of the spring telescopic tube 324 are in a closed state. After entering the spring telescopic tube 324, the gas extends outward, causing the cutting blade 328 to move synchronously to cut the sewing thread 116. As the spring telescopic tube 324 extends outward... It will contact and compress with the spring block 327 at the other end. After the spring blocks 327 at both ends contact and compress, the spring block 327 will contract inward. At this time, the adjusting block 326 will be stuck in another groove of the spring block 327. Then, the groove at the bottom of the spring block 327 will make the inside of the spring telescopic tube 324 communicate with the outside, allowing the gas entering the spring telescopic tube 324 to flow outward through the groove at the bottom of the spring block 327. After the air intake stops, under the action of the spring inside the spring telescopic tube 324, the spring telescopic tube 324 begins to contract, and... Spring block 4 327 contacts the fixing strip 325, allowing spring block 4 327 to reset. Adjusting block 2 326 then re-locks into the groove in front of spring block 4 327, and the top of spring telescopic tube 324 closes again. Through the operation of the above components, when spring telescopic tube 324 extends outward, the cutting blade 328 can cut the sewing thread 116, avoiding the situation where the break point is close to fixing block 1 212, resulting in a large amount of sewing thread 116 remaining at the bottom. In this case, the sewing thread 116 will be bent downward under pressure, thus affecting subsequent clamping.

[0032] A specific application of this embodiment is as follows: Before using the device, first install the device in the required position, then secure the sewing thread 116 in the groove of the lower base 221, and connect the power supply to the motor 121. When the motor 121 is powered on, it synchronously drives the threaded column 122 to rotate. When the threaded column 122 rotates, it can drive the adjusting block 124 to move up and down. When the adjusting block 124 moves down, the sensor 211 drives the fixing block 212 to move down. When the fixing block 212 moves down, it will cause the sliding block 213 to contact the top of the spring block 224. The sliding block 213 will be pressed upward. When the sliding block 213 moves upward, it will generate a negative pressure inside the fixing block 212, causing the spring block 214 to move upward. The inner contraction causes the spring blocks 214 at both ends to open together. After the sliding block 213 reaches the top, the fixing block 212 continues to move downward, which will compress the spring block 224 to move downward. After the spring block 224 moves to the bottom, the action of the spring block 225 will cause the locking strip 226 to be locked in the groove of the spring block 224, thereby restricting the movement of the spring block 224. When the fixing block 212 moves upward, the spring block 224 cannot move because it is locked. At this time, the action of the spring block 214 will cause the spring blocks 214 at both ends to move outward to form a clamping state, clamping the sewing thread 116. Then, the fixing block 212 moves upward together with the sewing thread 116, until it reaches the roller slider 215 and the inclined protrusion 216. Upon contact, the roller slider 215 will be pressed inward, and the gas on its side will enter the fixed block 212 through the air pressure pipe 217, pushing the spring block 214 to further clamp the sewing thread 116, maintaining a strong clamping force. Simultaneously, as the roller slider 215 retracts, the inclined slider 218 will also contact the adjusting block 124 and retract under pressure, allowing gas on one side to enter the fixed block 212 through the air pressure pipe 219, pushing the spring block 225 to clamp the bottom of the sewing thread 116. As the spring block 225 moves, it simultaneously drives the locking strip 226 to move, causing the locking strip 226 to leave the groove of the spring block 224. Then, the spring block 224 returns to its original position through springback, clamping both ends before continuing... The continued movement will perform a tensile test on the sewing thread 116 until it breaks. The control box 112 will then generate a data report for this section of the sewing thread 116. The fixing block 212 will then continue to descend for the next tensile test. This process repeats, allowing the device to automatically perform tensile tests on multiple sections of the sewing thread 116 after it is secured in the lower base 221. This avoids the need to clamp both ends of the sewing thread 116 during each test, which is time-consuming, labor-intensive, and inefficient. After the spring blocks 214 at both ends retract inward, the distance between them increases. The broken sewing thread 116 will then fall downward as it is no longer subject to clamping force after the spring blocks 214 move away from it.When the sliding block 213 contacts and presses against the spring block 224, the sliding block 213 will move upward first. This will cause the broken sewing thread 116 to fall downward when the fixed block 212 is still some distance away from the lower base 221. Through the operation of the above components, the broken sewing thread 116 can be made to fall downward automatically when the fixed block 212 is a certain distance away from the lower base 221. This avoids the inconvenience of manual adjustment required when the broken sewing thread 116 is clamped, and also avoids the problem of the broken sewing thread 116 not falling automatically when clamped, and the inconvenience of the distance being too close. If the sewing thread 116 breaks, it will contact the lower base 221 and will not fall downwards, remaining at the clamping point of the spring block 214. This would not affect the subsequent clamping of the sewing thread 116. Furthermore, the spring slider 222 and roller 223 can clamp the sewing thread 116 to a certain extent without affecting its movement, ensuring that the sewing thread 116 maintains a certain tension when pulled upwards. This prevents the sewing thread 116 from becoming loose during pulling, thus avoiding problems with subsequent tension testing of the sewing thread 116.

[0033] Utilizing the aforementioned characteristic that spring block 224 moves up and down, a pressure box 312 is installed. When spring block 224 moves downward, it compresses the gas at its bottom, forcing it into the pressure box 312 through the pressure pipe 311. After entering the pressure box 312, due to the characteristics of the conical groove 313, the gas pressure gradually increases as it flows upward because the space at the top becomes increasingly smaller. The gas is then ejected outward through the air outlet 314, blowing the fallen sewing thread 116 on top of the lower base 221 to one side, preventing the fallen sewing thread 116 from getting tangled on subsequent sewing threads 116, thus preventing subsequent... The pulling and testing of the sewing thread 116 are affected, causing some deviations in the test results. In addition, when the gas flows upward, it will also be sprayed outward through the air outlet 315. Since the spring block 214 contracts inward when it descends, the sprayed gas can directly act on the side of the spring block 214 when it approaches the lower base 221. This avoids the sewing thread 116 from deforming and sticking to the side of the spring block 214 during the tensile test due to the large clamping force. This would affect the clamping of the sewing thread 116 in the next round of testing, thus affecting the test.

[0034] Utilizing the characteristic that spring block 224 moves up and down under pressure, a piston plate 321 is installed. When spring block 224 moves downward, it synchronously drives piston plate 321 downward. As 321 moves upward, it compresses the gas at its bottom, forcing the gas through air pressure pipe 322 into spring telescopic tube 324. At this time, under the action of adjusting block 2 326, spring block 327 and the head of spring telescopic tube 324 are in a closed state. After the gas enters spring telescopic tube 324, it extends outward, driving the cutting blade 328 to move synchronously to cut the sewing thread 116. When spring telescopic tube 324 extends outward, it contacts and compresses spring block 327 at the other end. After the two ends of spring block 327 contact and compress, spring block 327 retracts inward. At this time, adjusting block 2 326 will be locked into another groove of spring block 327. The groove at the bottom of spring block 327 allows the interior of spring telescopic tube 324 to communicate with the outside, enabling gas entering spring telescopic tube 324 to flow outward through the groove at the bottom of spring block 327. After the air intake stops, the spring telescopic tube 324 begins to contract under the action of the spring inside, causing spring block 327 to contact the fixing strip 325 and reset spring block 327. Adjusting block 326 then re-locks onto the previous groove of spring block 327, and the top of spring telescopic tube 324 closes again. Through the operation of the above components, when spring telescopic tube 324 extends outward, the cutting blade 328 can cut the sewing thread 116, preventing a large amount of sewing thread 116 from remaining at the bottom due to the break being close to fixing block 212. In this case, the sewing thread 116 will be bent downward under pressure, affecting subsequent clamping.
