In response to the above problems, the following solutions are proposed. Summary of the invention

[0005] A clamp mechanism, the clamp mechanism includes a tension detector fixedly connected to the top of the second sliding plate, a mounting plate fixedly connected to the top of the tension detector, a CNC motor fixedly connected to the side wall of the mounting plate, a rotating column fixedly connected to the output shaft of the CNC motor, an arc plate rotatably connected to the side wall of the rotating column, a spring telescopic rod 1 fixedly connected to the top of the second sliding plate, an L-shaped rod 1 fixedly connected to one end of the spring telescopic rod 1 away from the second sliding plate, and a limiting arc plate fixedly connected to the side wall of the mounting plate;

[0006] The clamping mechanism includes a fixed rod fixedly connected to the side wall of the bottom plate, a track fixedly connected to the side wall of the fixed rod, two sliding clamps slidably connected to the inner wall of the track, a spring 1 fixedly connected to the side walls of the two sliding clamps, one end of the spring 1 away from the sliding clamp is fixedly connected to the side wall of the fixed rod, a folding rod 1 is rotatably connected between the two sliding clamps, and a folding rod 2 is rotatably connected between the two sliding clamps. In order to solve the problem that the sewing thread is affected by the clamp and causes measurement errors, a clamp mechanism is provided inside the device. Before use, the sewing thread is placed inside the rolling column, and the end of the sewing thread is pulled downward to present a Figure 3The power of the CNC motor is turned on. The CNC motor drives the rotating column and the arc plate to rotate counterclockwise. The rotating arc plate is blocked by the limiting arc plate, and drives the sewing thread to rotate toward the rotating column, so that the arc plate and the rotating column clamp the sewing thread. After the arc plate clamps the sewing thread, it rotates to force the side wall of the sewing thread to contact the side wall of the rotating column, presenting a Figure 4 In the middle G state, as the rotating column continues to rotate, the clamping position of the sewing thread and the clamping mechanism will eventually be away from the force-bearing position of the sewing thread, and then the electric telescopic rod will be contracted, and the electric telescopic rod will drive the sliding plate 2 and the clamping mechanism to move downward. At this time, the sliding plate 2 drives the L-shaped rod to move downward through the spring telescopic rod 1, and the protruding block of the L-shaped rod 1 contacts the outer wall of the folding rod 2, forcing the folding rod 2 to bend. The bent folding rod 2 drives the sliding clamps at both ends to approach each other and clamp the sewing thread in the middle. At this time, the top of the sewing thread is clamped by the sliding clamp and the bottom is clamped by the clamping mechanism. As the electric telescopic rod continues to move downward, the tensile strength of the sewing thread will be tested. Through the application of the above components, the clamping position of the sewing thread is kept away from the pressure position, thereby reducing the test error.

[0007] Preferably, the transmission component includes a fixed plate fixedly connected to the side wall of the bottom plate, the bottom of the fixed plate is fixedly connected to the air pressure box, the side wall of the air pressure box is connected with a one-way valve, and the inner wall of the air pressure box is slidably connected with a piston plate.

[0008] Preferably, the transmission assembly also includes a contact rod fixedly connected to the bottom of the piston plate, a spring 2 is fixedly connected to the top of the piston plate, and a transmission pipe is connected through the top of the air pressure box.

[0009] Preferably, the test assembly includes a mounting frame fixedly connected to the side wall of the base plate, a mounting slide rod is slidably connected to the inner wall of the through hole of the mounting frame, and a roller 1 is fixedly connected to the side wall of the mounting slide rod.

[0010] Preferably, the test assembly also includes a pressure box fixedly connected to the side wall of the mounting frame, a pressure relief button is connected through the side wall of the pressure box, a pneumatic telescopic rod is connected through the top of the pressure box, an end of the pneumatic telescopic rod away from the pressure box is fixedly connected to an arc-shaped push plate, a rotating groove is provided on the side wall of the bottom plate, an L-shaped rotating rod is rotatably connected to the inner wall of the rotating groove, a spring telescopic rod three is fixedly connected to the inner wall of the rotating groove, and an arc-shaped block is fixedly connected to the other end of the spring telescopic rod three. The characteristic of the above-mentioned electric telescopic rod driving the sliding plate two to move up and down is utilized, and a test assembly and a transmission assembly are arranged inside the equipment, wherein, before not in use, ensure that the L-shaped rotating rod is in Figure 8As the sliding plate 2 moves downward for the first time, the sliding plate 2 will drive the L-shaped rotating rod to rotate around the connection point, and after the sliding plate 2 completely passes the L-shaped rotating rod, the L-shaped rotating rod is subjected to self-repositioning. After completing the sewing thread tensile strength test, the electric telescopic rod drives the sliding plate 2 to move upward. At this time, the sliding plate 2 will force the L-shaped rotating rod to rotate upward. At this time, the side of the L-shaped rotating rod will contact the side wall of the arc block. Under the push of the spring telescopic rod 3, after one end of the L-shaped rotating rod passes the arc block, the arc block will restrict the L-shaped rotating rod. At this time, the L-shaped rotating rod is as follows Figure 8 In the state of middle E, after the clamp mechanism grabs the sewing thread again, the sliding plate 2 drives the clamp mechanism to move downward, and after the sliding clamp completes clamping the top of the sewing thread, the bottom of the sliding plate 2 will contact the side wall of the L-shaped rotating rod. At this time, the sliding plate 2 cannot move downward again, and the contracted electric telescopic rod will force the sliding plate 1 to move upward along the inner wall of the slide groove, and the upward sliding plate 1 will contact the bottom of the contact rod. The contact rod compresses the internal gas of the air pressure box through the piston plate and transmits it to the pressure box and the air pressure telescopic rod through the transmission pipe, forcing the air pressure telescopic rod to extend. The extended air pressure telescopic rod drives the arc push plate to contact the outer wall of roller 1. Roller 1 is compressed, driving the installation slide rod to contact the outer wall of the sewing thread. At this time, various instruments installed on the installation slide rod, such as chemical testing instruments and grinding testing instruments, can directly act on the side wall of the sewing thread. Through the application of the above components, the equipment can perform various data detection on the wire to improve the detection accuracy.

[0011] Preferably, the fuse assembly includes a fixed bracket fixedly connected to the side wall of the bottom plate, a fuse is slidably connected to the inner wall of the fixed bracket, and a roller 2 is rotatably connected to the side wall of the fuse. After completing a single test, the electric telescopic rod is extended, and the sliding plate 1 moves down along the slide slot, and the sliding plate 2 moves upward. In this process, the spring 2 releases mechanical power to force the piston plate to reset. During the process of resetting the piston plate, the air pressure box will replenish the internal air through the one-way valve, and when the clamp mechanism moves to the highest point, the L-shaped rod 1 will push the folding rod 1 to fold, and the folded folding rod 1 drives the sliding clamps at both ends to clamp again. At this time, the clamp formed by the arc plate and the rotating column will be at the bottom of the clamp gap of the sliding clamp. The bottom of the sewing thread will enter the clamping gap between the rotating column and the arc plate again, and then the rotating column rotates to realize autonomous wiring of the sewing thread. Subsequently, the electric telescopic rod contracts, and the second sliding plate descends and contacts the outer wall of the L-shaped rotating rod. The first sliding plate rises, forcing the internal gas of the pneumatic box to enter the inside of the pneumatic telescopic rod. The arc push plate contacts another roller, forcing the corresponding installation slide bar to move outward. Through the application of the above components, autonomous wire pulling of the equipment is realized. In addition, each time the arc push plate moves up, only one installation slide bar can move outward, and the rest are in a contracted state due to the pull of their own springs. Multiple installation slide bars are divided into multiple processes to avoid interference between multiple testing instruments and affect the detection effect of the equipment.

[0012] Preferably, the fuse assembly also includes an L-shaped rod 2 which is slidably connected to the side wall of the fixed bracket, a protrusion is fixedly connected to the side wall of the L-shaped rod 2, and a rotating rod is rotatably connected to the side wall of the L-shaped rod 2. Utilizing the characteristics of the above-mentioned sliding plate 2 moving up and down, an L-shaped rod 2 and a rotating rod are arranged inside the equipment. After each sliding plate 2 completes the detection, the sewing thread will break. When the sliding plate 2 moves upward to perform the wiring process, the sliding plate 2 will drive the protrusion and the rotating rod to move upward through the L-shaped rod 2. At this time, the inclined rotating rod will contact the outer wall of the roller 2. The inclined surface of the rotating rod will force the fuse to slide along the inside of the fixed bracket, forcing the fuse to move in the direction of the sewing thread. The high-temperature fuse will heat the sewing thread made of polytetrafluoroethylene, forcing the sewing thread to shrink. Through the application of the above-mentioned components, the polytetrafluoroethylene sewing thread can be prevented from curling after being pulled, thereby affecting the autonomous wiring effect of the clamping mechanism.

[0013] A method for using a strength detection device for producing polytetrafluoroethylene sewing thread comprises the following steps:

[0014] S1: Place the sample;

[0015] S2: connecting thread;

[0016] S3: Turn on the power.

[0017] The present invention has the following beneficial effects:

[0018] (1) The present invention aims to solve the problem that the sewing thread is affected by the clamp and causes measurement errors. A clamp mechanism is provided inside the device. Before use, the sewing thread is placed inside the rolling column and the end of the sewing thread is pulled downward to present a Figure 3 The power of the CNC motor is turned on. The CNC motor drives the rotating column and the arc plate to rotate counterclockwise. The rotating arc plate is blocked by the limiting arc plate, and drives the sewing thread to rotate toward the rotating column, so that the arc plate and the rotating column clamp the sewing thread. After the arc plate clamps the sewing thread, it rotates to force the side wall of the sewing thread to contact the side wall of the rotating column, presenting a Figure 4In the middle G state, as the rotating column continues to rotate, the clamping position of the sewing thread and the clamping mechanism will eventually be away from the force-bearing position of the sewing thread, and then the electric telescopic rod will be contracted, and the electric telescopic rod will drive the sliding plate 2 and the clamping mechanism to move downward. At this time, the sliding plate 2 drives the L-shaped rod to move downward through the spring telescopic rod 1, and the protruding block of the L-shaped rod 1 contacts the outer wall of the folding rod 2, forcing the folding rod 2 to bend. The bent folding rod 2 drives the sliding clamps at both ends to approach each other and clamp the sewing thread in the middle. At this time, the top of the sewing thread is clamped by the sliding clamp and the bottom is clamped by the clamping mechanism. As the electric telescopic rod continues to move downward, the tensile strength of the sewing thread will be tested. Through the application of the above components, the clamping position of the sewing thread is kept away from the pressure position, thereby reducing the test error.

[0019] (2) The present invention utilizes the characteristics of the electric telescopic rod driving the sliding plate 2 to move up and down, and a test component and a transmission component are arranged inside the device, wherein, before use, ensure that the L-shaped rotating rod is in Figure 8 As the sliding plate 2 moves downward for the first time, the sliding plate 2 will drive the L-shaped rotating rod to rotate around the connection point, and after the sliding plate 2 completely passes the L-shaped rotating rod, the L-shaped rotating rod is subjected to self-repositioning. After completing the sewing thread tensile strength test, the electric telescopic rod drives the sliding plate 2 to move upward. At this time, the sliding plate 2 will force the L-shaped rotating rod to rotate upward. At this time, the side of the L-shaped rotating rod will contact the side wall of the arc block. Under the push of the spring telescopic rod 3, after one end of the L-shaped rotating rod passes the arc block, the arc block will restrict the L-shaped rotating rod. At this time, the L-shaped rotating rod is as follows Figure 8 In the state of middle E, after the clamp mechanism grabs the sewing thread again, the sliding plate 2 drives the clamp mechanism to move downward, and after the sliding clamp completes clamping the top of the sewing thread, the bottom of the sliding plate 2 will contact the side wall of the L-shaped rotating rod. At this time, the sliding plate 2 cannot move downward again, and the contracted electric telescopic rod will force the sliding plate 1 to move upward along the inner wall of the slide groove, and the upward sliding plate 1 will contact the bottom of the contact rod. The contact rod compresses the internal gas of the air pressure box through the piston plate and transmits it to the pressure box and the air pressure telescopic rod through the transmission pipe, forcing the air pressure telescopic rod to extend. The extended air pressure telescopic rod drives the arc push plate to contact the outer wall of roller 1. Roller 1 is compressed, driving the installation slide rod to contact the outer wall of the sewing thread. At this time, various instruments installed on the installation slide rod, such as chemical testing instruments and grinding testing instruments, can directly act on the side wall of the sewing thread. Through the application of the above components, the equipment can perform various data detection on the wire to improve the detection accuracy.

[0020] (3) After completing a single test, the electric telescopic rod of the present invention is extended. At this time, the sliding plate 1 moves down along the slide groove, and the sliding plate 2 moves upward. During this process, the spring 2 releases the mechanical power to force the piston plate to reset. During the process of the piston plate resetting, the air pressure box will replenish the internal air through the one-way valve. When the clamp mechanism moves up to the highest point, the L-shaped rod 1 will push the folding rod 1 to fold. The folded folding rod 1 drives the sliding clamps at both ends to clamp again. At this time, the clamp formed by the arc plate and the rotating column will be at the bottom of the sliding clamp gap, and the bottom of the sewing thread will enter the clamp between the rotating column and the arc plate again. Then The rotating column rotates to realize autonomous wiring of the sewing thread, and then the electric telescopic rod contracts, the second sliding plate descends and contacts the outer wall of the L-shaped rotating rod, and the first sliding plate rises, forcing the internal gas of the pneumatic box to enter the inside of the pneumatic telescopic rod, and the arc-shaped push plate contacts another roller, forcing the corresponding installation slide bar to move outward. Through the application of the above components, autonomous wire pulling of the equipment is realized. In addition, each time the arc-shaped push plate moves up, only one installation slide bar can move outward, and the rest are in a contracted state due to the pull of their own springs. Multiple installation slide bars are divided into multiple processes to avoid interference between multiple testing instruments and affect the detection effect of the equipment.

[0021] (4) The present invention utilizes the characteristic of the sliding plate 2 moving up and down, and an L-shaped rod 2 and a rotating rod are arranged inside the equipment. Each time the sliding plate 2 completes the detection, the sewing thread will be broken. When the sliding plate 2 moves upward to perform the wiring process, the sliding plate 2 will drive the protrusion and the rotating rod to move upward through the L-shaped rod 2. At this time, the inclined rotating rod will contact the outer wall of the roller 2. The inclined surface of the rotating rod will force the fuse to slide along the inside of the fixed bracket, forcing the fuse to move in the direction of the sewing thread. The high-temperature fuse will heat the polytetrafluoroethylene sewing thread, forcing the sewing thread to shrink. Through the application of the above-mentioned components, the polytetrafluoroethylene sewing thread can be prevented from curling after being pulled, thereby affecting the autonomous wiring effect of the clamping mechanism.

In this process, the spring 2 45 releases mechanical power to force the piston plate 44 to reset. During the reset of the piston plate 44, the air pressure box 42 will replenish the internal air through the one-way valve 43, and when the clamp mechanism 2 moves to the highest point, the L-shaped rod 1 27 will push the folding rod 1 35 to fold, and the folded folding rod 1 35 drives the sliding clamps 33 at both ends to clamp again. At this time, the clamp formed by the arc plate 25 and the rotating column 24 will be in the gap between the sliding clamps 33. The bottom of the sewing thread 12 will enter the clamping gap between the rotating column 24 and the arc plate 25 again, and then the rotating column 24 rotates to realize the autonomous wiring of the sewing thread 12. Subsequently, the electric telescopic rod 15 contracts, and the sliding plate 2 16 descends and contacts the outer wall of the L-shaped rotating rod 59, and the sliding plate 14 rises, forcing the internal gas of the air pressure box 42 to enter the air pressure telescopic rod 56, and the arc push plate 57 contacts another roller 1 53, forcing the corresponding installation slide bar 52 to move outward. Through the application of the above components, the autonomous wire pulling of the equipment is realized. In addition, each time the arc push plate 57 moves up, only one installation slide bar 52 can move outward, and the rest are in a contracted state due to the pull of their own springs. Multiple installation slide bars 52 are split into multiple processes to avoid interference between multiple detection instruments and affect the detection effect of the equipment.

[0043] The fuse assembly 6 also includes an L-shaped rod 64 slidably connected to the side wall of the fixed bracket 61, a protrusion 65 is fixedly connected to the side wall of the L-shaped rod 64, and a rotating rod 66 is rotatably connected to the side wall of the L-shaped rod 64. By utilizing the characteristics of the above-mentioned sliding plate 16 moving up and down, the L-shaped rod 64 and the rotating rod 66 are arranged inside the device. After each sliding plate 16 completes the detection, the sewing thread 12 will break. When the sliding plate 16 moves upward to perform the wiring process, the sliding plate 16 will be brought by the L-shaped rod 64. The movable protrusion 65 and the rotating rod 66 move upward, and the inclined rotating rod 66 will contact the outer wall of the roller 2 63. The inclined surface of the rotating rod 66 will force the fuse 62 to slide along the inside of the fixed bracket 61, forcing the fuse 62 to move in the direction of the sewing thread 12. The high-temperature fuse 62 will heat the polytetrafluoroethylene sewing thread, forcing the sewing thread to shrink. Through the application of the above components, the polytetrafluoroethylene sewing thread can be prevented from curling after being pulled, which will affect the autonomous wiring effect of the clamp mechanism 2.

[0044] The method for using the sewing thread testing device comprises the following steps:

[0045] S1: Place the sample;

[0046] S2: connecting thread;

[0047] S3: Turn on the power.

[0048] A specific application of this embodiment is: before use, the sewing thread 12 is placed inside the rolling column 11, and the end of the sewing thread 12 is pulled downward to present a Figure 3 The power supply of the numerical control motor 23 is turned on. At this time, the numerical control motor 23 drives the rotating column 24 and the arc plate 25 to rotate counterclockwise. The rotating arc plate 25 is blocked by the limiting arc plate 28, and drives the sewing thread 12 to rotate toward the rotating column 24, so that the arc plate 25 and the rotating column 24 clamp the sewing thread 12. After the arc plate 25 clamps the sewing thread 12, it rotates to force the side wall of the sewing thread 12 to contact the side wall of the rotating column 24, presenting as shown in the figure. Figure 4 In the middle G state, as the rotating column 24 continues to rotate, the clamping position of the sewing thread 12 and the clamping mechanism 2 will eventually be away from the force-bearing position of the sewing thread 12, and then the electric telescopic rod 15 will be retracted, and the electric telescopic rod 15 will drive the sliding plate 2 16 and the clamping mechanism 2 to move downward. At this time, the sliding plate 2 16 drives the L-shaped rod 1 27 to move downward through the spring telescopic rod 1 26, and the protruding block of the L-shaped rod 1 27 contacts the outer wall of the folding rod 2 36, forcing the folding rod 2 36 to bend. The bent folding rod 2 36 drives the sliding clamps 33 at both ends to approach each other and clamp the sewing thread 12 in the middle. At this time, the top of the sewing thread 12 is clamped by the sliding clamp 33, and the bottom is clamped by the clamping mechanism 2. As the electric telescopic rod 15 continues to move downward, the tensile strength of the sewing thread 12 will be tested. Through the application of the above-mentioned components, the clamping position of the sewing thread 12 is away from the pressure position, thereby reducing the test error.

[0049] By utilizing the characteristics of the electric telescopic rod 15 driving the sliding plate 16 to move up and down, a test assembly 5 and a transmission assembly 4 are arranged inside the device, wherein, before not being used, ensure that the L-shaped rotating rod 59 is in the Figure 8 As a whole of middle F, as the sliding plate 2 16 moves downward for the first time, the sliding plate 2 16 will drive the L-shaped rotating rod 59 to rotate around the connection point as the center, and after the sliding plate 2 16 completely passes the L-shaped rotating rod 59, the L-shaped rotating rod 59 is subjected to self-repositioning. After completing the sewing thread tensile strength test, the electric telescopic rod 15 drives the sliding plate 2 16 to move upward. At this time, the sliding plate 2 16 will force the L-shaped rotating rod 59 to rotate upward. At this time, the side of the L-shaped rotating rod 59 will contact the side wall of the arc block 511. Under the push of the spring telescopic rod 3 510, after one end of the L-shaped rotating rod 59 passes the arc block 511, the arc block 511 will restrict the L-shaped rotating rod 59. The L-shaped rotating rod 59 is now as shown in the figure. Figure 8In the state E, after the clamp mechanism 2 grabs the sewing thread 12 again, the sliding plate 16 drives the clamp mechanism 2 to move downward. After the sliding clamp block 33 completes the clamping of the top of the sewing thread 12, the bottom of the sliding plate 16 will contact the side wall of the L-shaped rotating rod 59. At this time, the sliding plate 16 cannot move downward again, and the retracted electric telescopic rod 15 will force the sliding plate 14 to move upward along the inner wall of the slide groove 13. The upward sliding plate 14 will contact the bottom of the contact rod 46, and the contact rod 46 presses the inside of the air pressure box 42 through the piston plate 44. The gas is transmitted to the pressure box 54 and the pneumatic telescopic rod 56 through the transmission pipe 47, forcing the pneumatic telescopic rod 56 to extend. The extended pneumatic telescopic rod 56 drives the arc push plate 57 to contact the outer wall of the roller 53. The roller 53 is pressurized, driving the mounting slide bar 52 to contact the outer wall of the sewing thread 12. At this time, various instruments installed on the mounting slide bar 52, such as chemical detection instruments and grinding detection instruments, can directly act on the side wall of the sewing thread 12. Through the application of the above components, the equipment can perform various data detection on the wire and improve the detection accuracy.

[0050] After completing a single test, the electric telescopic rod 15 is extended, and the sliding plate 14 moves down along the slide groove 13, and the sliding plate 2 16 moves upward. During this process, the spring 2 45 releases mechanical power to force the piston plate 44 to reset. During the resetting of the piston plate 44, the air pressure box 42 will replenish the internal air through the one-way valve 43. When the clamp mechanism 2 moves to the highest point, the L-shaped rod 27 will push the folding rod 35 to fold, and the folded folding rod 35 drives the sliding clamps 33 at both ends to clamp again. At this time, the clamp formed by the arc plate 25 and the rotating column 24 will be at the bottom of the gap between the sliding clamp 33, and the bottom of the sewing thread 12 will enter the clamp between the rotating column 24 and the arc plate 25 again. , then the rotating column 24 rotates to realize the autonomous wiring of the sewing thread 12, then the electric telescopic rod 15 contracts, the sliding plate 2 16 descends and contacts the outer wall of the L-shaped rotating rod 59, the sliding plate 14 rises, forcing the internal gas of the air pressure box 42 to enter the air pressure telescopic rod 56, and the arc push plate 57 contacts another roller 1 53, forcing the corresponding installation slide bar 52 to move outward. Through the application of the above components, the autonomous wiring of the equipment is realized. In addition, each time the arc push plate 57 moves up, only one installation slide bar 52 can move outward, and the rest are in a contracted state due to the pull of their own springs. Multiple installation slide bars 52 are split into multiple processes to avoid interference between multiple detection instruments and affect the detection effect of the equipment.

[0051] Taking advantage of the up and down movement of the above-mentioned sliding plate 16, an L-shaped rod 64 and a rotating rod 66 are provided inside the equipment. Each time the sliding plate 16 completes the detection, the sewing thread 12 will break. When the sliding plate 16 moves upward to perform the wiring process, the sliding plate 16 will drive the protrusion 65 and the rotating rod 66 to move upward through the L-shaped rod 64. At this time, the inclined rotating rod 66 will contact the outer wall of the roller 63. The inclined surface of the rotating rod 66 will force the fuse 62 to slide along the inside of the fixed bracket 61, forcing the fuse 62 to move in the direction of the sewing thread 12. The high-temperature fuse 62 will heat the polytetrafluoroethylene sewing thread, forcing the sewing thread to shrink. Through the application of the above-mentioned components, the polytetrafluoroethylene sewing thread can be prevented from curling after being pulled, thereby affecting the autonomous wiring effect of the clamp mechanism 2.
