Description

Technical Field

[0001] The invention relates to the technical field of sewing thread detection, and in particular to a sampling detection device for sewing thread detection. Background Art

[0002] Sewing thread is the thread needed for knitted clothing products. Sewing thread can be divided into three categories according to raw materials: natural fiber, synthetic fiber sewing thread and mixed sewing thread. With the development of polyester industry, more and more sewing threads use pure polyester fiber as their raw material.

[0003] When sewing thread is produced, two strands of thread are cross-wound to improve the strength of the sewing thread. Therefore, the twist standards of sewing thread in different usage scenarios are different. Currently, the twist detection of sewing thread is mostly done manually, which makes the detection efficiency low. In addition, in order to avoid the sewing thread from pilling or breaking during use, silicone oil is generally added to the sewing thread during the production process to make the sewing thread more lubricated and reduce its friction. Since silicone oil is colorless and odorless, it is difficult to detect if silicone oil is not added to the sewing thread during production, which makes it easy for subsequent users to experience problems such as breakage or pilling when using the sewing thread without silicone oil, affecting the quality of the sewing thread. Therefore, a sampling and detection device for sewing thread detection is proposed. Summary of the invention

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Embodiment 1, refer to Figure 1-9A sampling and testing device for sewing thread detection comprises a testing platform 1 and two symmetrical moving platforms 2, the testing platform 1 is connected with two parallel electrically controlled slide rails 3, the moving platform 2 is slidably connected with the two electrically controlled slide rails 3 through two slide seats 4, the top of the testing platform 1 is connected with two opposite testing dishes 7 through a rotating ring 6, a vertical tube 9 is arranged in the rotating ring 6, and a laser 11 is connected to the outer wall of the vertical tube 9;

[0031] Further, the top of the detection platform 1 is fixedly connected to the bottom end of the electric control slide rail 3, the top of the detection platform 1 is fixedly connected to an electric push rod 5 through a fixed plate, the electric push rod 5 is located directly above the detection dish 7 on one side, the top of the detection platform 1 is rotatably connected to the bottom end of the rotating ring 6, the groove at the top of the rotating ring 6 is magnetically connected to the bottom end of the detection dish 7, the top of one side of the detection dish 7 is fixedly connected to a guide half pipe 8, the top of the detection platform 1 is fixedly connected to the bottom end of the vertical pipe 9, one side of the top of the vertical pipe 9 is fixedly connected to an injection pipe 10, the injection pipe 10 is connected to a gear pump through the vertical pipe 9, the other side of the top of the vertical pipe 9 is fixedly connected to a laser 11, and a photosensitive plate 12 is arranged outside the detection dish 7 on the other side;

[0032] It should be noted that: a section of the sewing thread just produced is taken and first wound on the electric push rod 5, and the two ends of the sampled sewing thread are fixed respectively, one end of which is wound on the winding rod 15 of the stop plate 14 on the left movable platform 2, and two hydraulic cylinders 16 are used to push the two limit plates 17 to further clamp and limit the sewing thread, and the other end passes through the detection ring 25 on the right movable platform 2, and the thread end of this end is untied and placed between the two grinding plates 24. The two clamping plates 27 in the detection ring 25 clamp and limit the sewing thread through the hydraulic push rod 26, and then the electric push rod 5 is returned to its position, so that the wound sewing thread is pushed out and falls into the detection dish 7 directly below. The water in the detection dish 7 soaks the sewing thread and causes part of the silicone oil to precipitate. After soaking, the sewing thread is straightened using the left and right movable platforms 2. The silicone oil is insoluble in water and will float on the water surface. The gear pump will slowly inject water into the guide half pipe 8 through the injection pipe 10 to prevent splashing or large ripples when the water is injected. There is a light sensor on the inner wall of the detection dish 7, that is, the injection of water is stopped when the water level reaches a fixed height. This is a prior art and will not be described in detail. Then slowly rotate the rotating ring 6 to allow the two detection dishes 7 to exchange positions. If silicone oil is added to the sewing thread, a layer of silicone oil will float on the water surface of the detection dish 7. The laser 11 irradiates from above through the refraction of the silicone oil layer and the water layer. The change in the medium will cause the angle of the refracted light to change greatly. Whether the photosensitive plate 12 senses the change can tell whether silicone oil is added to the sewing thread normally. After the detection, the operator pours out the liquid in the detection dish 7 for cleaning and puts it in place. The injection pipe 10 can continue to inject water into the turned detection dish 7.

[0033] A further advantage of adopting the above method is that it can detect whether the sewing thread just produced has been added with silicone oil, making the detection result faster and more intuitive, and avoiding the output without adding silicone oil affecting the normal use of users.

[0034] Example 2, reference Figure 1-9 The inner side wall of the mobile platform 2 on the left side is connected with a strength component, and hydraulic cylinders 16 are respectively arranged on both sides of the strength component. The ends of the hydraulic cylinders 16 are connected with limit plates 17, and the half end surface of the limit plate 17 away from the left mobile platform 2 is a rubber surface;

[0035] Furthermore, the strength component is composed of a spring rod 13 and a stop plate 14, the fixed end of the spring rod 13 is fixedly connected to the inner side wall of the left moving platform 2, the moving end of the spring rod 13 is fixedly connected to one end of the stop plate 14, the other end of the stop plate 14 is fixedly connected to a winding rod 15, an air pressure sensor is arranged in the spring rod 13, the side wall of the hydraulic cylinder 16 is fixedly connected to the inner side wall of the left moving platform 2, the output end of the hydraulic cylinder 16 is fixedly connected to the end of the limit plate 17, and a laser sensor plate 19 is arranged next to the limit plate 17 on one side;

[0036] It should be noted that: after the mobile platforms 2 on the left and right sides pull up the sampled sewing thread, the mobile platform 2 on the left side is kept fixed, and the mobile platform 2 on the right side moves slowly under the control of the electric control slide rail 3. At the same time, the limit of the limit plate 17 is released, and the sewing thread will pull the spring rod 13 through the winding rod 15 and the stop plate 14, and the air pressure in the spring rod 13 will change slowly. If the strength of the sewing thread is not good and it is broken during the detection process, the spring rod 13 will be reset instantly, and the air pressure therein will also increase instantly. The air pressure sensor in the spring rod 13 will sense and send out a signal, and directly issue an unqualified alarm. If it is qualified, the stop plate 14 will stop when it is pulled to the limit plate 17. After the detected pulling force is not broken, the limit plate 17 will clamp the tensioned sewing thread to limit it;

[0037] A further advantage of adopting the above method is that it can detect the strength of the sampled sewing thread under a certain tensile force, prevent the production of sewing thread with lower strength, and help to promptly discover the continuous strength failure caused by the production process.

[0038] Example 3, reference Figure 1-9 The inner side wall of the right-side movable platform 2 is connected to an adapter plate 21 through a rotating shaft, and the upper and lower side walls of the adapter plate 21 are connected to a branching assembly through two U-shaped plates 22. The ends of the U-shaped plates 22 are fixedly connected to a detection ring 25, and the inner side walls of the detection ring 25 are respectively connected to two opposite clamping plates 27 through two hydraulic push rods 26. The half end surface of the clamping plate 27 away from the right-side movable platform 2 is a rubber surface. Two mutually symmetrical T-shaped grooves are provided on the inner side wall of the detection ring 25, and the inner side wall of the T-shaped groove is connected to a sensing assembly. Suction buckets 32 are provided on both ends of the adapter plate 21;

[0039] Furthermore, the line splitter assembly is composed of two electric control push rods 23 and two grinding plates 24, the two electric control push rods 23 are respectively fixedly connected to the inner side walls of the two U-shaped plates 22, the output end of the electric control push rod 23 is fixedly connected to the end face of the grinding plate 24, the side wall of the right moving platform 2 is rotatably connected to the inner end face of the adapter plate 21 through a rotating shaft, a circle measuring instrument 20 is arranged on the rotating shaft, the two grinding plates 24 are centrally symmetrically arranged, the induction assembly is composed of a telescopic rod 28 and an induction arc plate 29, the inner side wall of the detection ring 25 is fixedly connected to the end of the clamping plate 27 through a hydraulic push rod 26, and the telescopic rod 28 The fixed end is fixedly connected to the inner wall of the T-slot in the detection ring 25, the piston rod end of the telescopic rod 28 is fixedly connected to the outer wall of the induction arc plate 29, the outer wall of the detection ring 25 is fixedly connected with the laser sensor 18, the telescopic rod 28 is provided with a pressure sensor, the outer end surface of the adapter plate 21 is fixedly connected to two micro air pumps 30 through two mounting plates, the output end of the micro air pump 30 is fixedly connected to an air pipe 31, the end of the air pipe 31 is threadedly connected to the end of the suction bucket 32, the inner wall of the air pipe 31 is fixedly connected to a hole plate 33, and the end of the hole plate 33 is rotatably connected to an impeller 34 through a pin shaft;

[0040] It should be noted that after the sampled sewing thread is tightened, the back and forth grinding of the grinding plate 24 facilitates the further dispersion of the already untied thread ends, so that the two strands of thread are twisted away from each other and separated on both sides under the action of the rotational force. At this time, the micro air pump 30 is started to evacuate air, and a relatively small power is used to suck in the two strands of thread close to the two suction buckets 32 on both sides. When the airflow flows, the impeller 34 on the orifice plate 33 will be driven to rotate slowly. Since the airflow is small, the torque of rotation is also small and the thread will not be broken. After being sucked in, the dispersed thread will be wound around the impeller 34 and fixed to the upper limit. At this time, the limit of the splint 27 is released. It should be noted that the adhesive surface of the limit plate 17 has adhesion to part of the surface of the thread, which can prevent the thread from rotating during the limit. Then the adapter plate 21 rotates on the movable table 2 through the rotating shaft to untwist the two strands of the sewing thread. The rotation process The circle measuring instrument 20 will measure and record the number of rotations similar to counting skipping ropes. The micro air pump 30 still runs at a relatively low power to keep the two strands of thread tightened. When the sewing thread is completely untwisted, the two strands of thread will be completely separated and further tightened. The two strands of thread will press the sensing arc plate 29 on the telescopic rod 28. After the pressure sensor in the telescopic rod 28 senses the change, it proves that the twist has been completely untwisted. At this time, the number of rotations recorded by the circle measuring instrument 20 is the twist amount, and the measuring distance between the laser sensor 18 and the laser sensing plate 19 is the distance for the sewing thread to detect the untwisting. Then, the twist of the sampled sewing thread can be obtained according to the twist calculation formula, so as to know whether the twist of the sampled sewing thread is within the qualified twist range. If there is a small number of untwisted twists in the detection ring 25, the twist value fluctuation caused can be ignored.

[0041] A further advantage of adopting the above method is that the twist of the sampled sewing thread can be tested, the twist of the two strands can be quickly released and the number of rotations can be accurately recorded, making the test faster and more accurate, and facilitating the understanding of the overall strength performance of the produced sewing thread.

[0042] Note: The calculation formula for twist is: twist = T / L, where T represents the amount of twisting of the yarn and L represents the unit length (inches or centimeters).

[0043] When the present invention is in use, a section of the sewing thread just produced is taken and first wound on the electric push rod 5, and the two ends of the sampled sewing thread are fixed respectively, one end of which is wound on the winding rod 15 of the stop plate 14 on the left movable platform 2, and two hydraulic cylinders 16 are used to push two limit plates 17 to further clamp and limit the sewing thread, and the other end passes through the detection ring 25 on the right movable platform 2, and the thread end of this end is untied and placed between the two grinding plates 24. The two clamping plates 27 in the detection ring 25 clamp and limit the sewing thread through the hydraulic push rod 26, and then the electric push rod 5 is returned to its position, so that the wound sewing thread is pushed out and falls into the detection dish 7 just below. The water in the detection dish 7 soaks the sewing thread and causes part of the silicone oil to precipitate. After soaking, the left and right movable platforms 2 are used to straighten the sewing thread. The silicone oil is insoluble in water and will float on the water surface. At this time, the gear pump will slowly inject water into the guide half pipe 8 through the injection pipe 10 to prevent water from being injected. When the sewing thread is filled with silicone oil, a layer of silicone oil will float on the water surface of the detection dish 7. The laser irradiated from the top by the laser 11 will be refracted by the silicone oil layer and the water layer. The change of the medium will cause the angle of the refracted light to change greatly. Whether the photosensitive plate 12 senses the change can know whether the sewing thread is normally added with silicone oil. After the detection, the operator pours out the liquid in the detection dish 7 for cleaning and puts it in place. The injection pipe 10 can continue to inject water into the turned detection dish 7, so that the sewing thread just produced can be tested for whether silicone oil is added, so that the test result is faster and more intuitive, avoiding the output without adding silicone oil affecting the normal use of users.

[0044] After the movable platforms 2 on the left and right sides pull up the sampled sewing thread, the movable platform 2 on the left side is kept fixed, and the movable platform 2 on the right side moves slowly under the control of the electric control slide rail 3. At the same time, the limit of the limit plate 17 is released, and the sewing thread will pull the spring rod 13 through the winding rod 15 and the stop plate 14, and the air pressure in the spring rod 13 will change slowly. If the strength of the sewing thread is not good and is broken during the detection process, the spring rod 13 will be reset instantly, and the air pressure therein will also increase instantly. The air pressure sensor in the spring rod 13 will sense and transmit a signal, and directly issue an unqualified alarm. If it is qualified, the stop plate 14 will stop when it is pulled to the limit plate 17. After the detected pulling force is not broken, the limit plate 17 will clamp and limit the tensioned sewing thread, so that the strength of the sampled sewing thread under a certain pulling force can be detected to prevent the output of sewing thread with low strength, and it is also convenient to help timely discover the continuous unqualified strength caused by the production process;

[0045] After the sampling sewing thread is tightened, the back and forth grinding of the grinding plate 24 facilitates the further dispersion of the already untied thread ends, so that the two strands of thread are twisted away from each other and separated on both sides under the action of the rotational force. At this time, the micro air pump 30 is started to evacuate air, and a relatively small power is used to suck in the two strands of thread close to the two suction buckets 32 on both sides. When the air flow flows, the impeller 34 on the orifice plate 33 will be driven to rotate slowly. Since the air flow is small, the torque of rotation is also small and the thread will not be broken. The dispersed thread will be wound around the impeller 34 and fixed at the upper limit after being sucked in. At this time, the limit of the clamping plate 27 is released. It should be noted that the adhesive surface of the limit plate 17 is adhered to the partial surface of the thread and has adhesion, which can prevent the thread from rotating during the limit. Then the adapter plate 21 rotates on the movable table 2 through the rotating shaft to untwist the two strands of the sewing thread. During the rotation, the circle measuring instrument 20 will measure and record the number of rotations similar to counting skipping ropes. The micro air pump 30 still uses a relatively small The power is running, and the two strands of thread are kept tightened. When the sewing thread is completely untwisted, the two strands of thread will be completely separated and further tightened, and the two strands of thread will press the sensing arc plate 29 on the telescopic rod 28. After the pressure sensor in the telescopic rod 28 senses the change, it proves that the twist has been completely untwisted. At this time, the number of rotations recorded by the circle measuring instrument 20 is the twist amount, and the measuring distance between the laser sensor 18 and the laser sensing plate 19 is the distance for the sewing thread to detect and release the twist. Then, the twist of the sampled sewing thread can be obtained according to the twist calculation formula, so as to know whether the twist of the sampled sewing thread is within the qualified twist range. If there are a small number of untwisted twisted circles in the detection ring 25, the twist value fluctuation caused can be ignored. In this way, the twist of the sampled sewing thread can be detected, the twist of the two strands of thread can be quickly released and the number of rotations can be accurately recorded, so that the detection is faster and more accurate, which is convenient for understanding the overall strength performance of the produced sewing thread.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
