Description

Technical Field

[0001] The present invention relates to the technical field of nylon detection, and specifically to a finished product detector for processing nylon elastic yarns. Background Art

[0002] Nylon elastic yarn is a synthetic fiber material with high strength, wear resistance and certain elasticity, and is widely used in fields such as clothing, sports equipment and medical products. In order to ensure that the processed nylon elastic yarn meets the predetermined performance standards, it is necessary to conduct strict inspections on it.

[0003] The patent with the patent announcement number CN218726099U relates to a finished product detector for processing nylon elastic yarns, including: a base and a machine body. The base has the machine body fixedly connected to its upper end. The detection structure includes a tensile force detector, which is fixedly connected to the upper end of the base. A connecting rod is fixedly connected to the side wall of the tensile force detector. One end of the connecting rod far from the tensile force detector is fixedly connected to a first moving rod. A nylon yarn is wound around the surface of the first moving rod. The bottom end of the first moving rod is inserted into a first sliding groove opened inside the base. The stable structure includes a support rod, which is fixedly connected to the lower end of the base. This patent realizes the tensile detection of nylon elastic yarn, and the device can maintain stability during detection, avoiding inaccurate detection readings caused by the overall instability of the device, and improving the practicability and stability of the device.

[0004] In the above patent, the tensile detection of nylon elastic yarn is realized, and the device can maintain stability during detection, avoiding inaccurate detection readings caused by the overall instability of the device, and improving the practicability and stability of the device. However, during detection, after the elastic yarn is fixed, it is necessary to stretch the elastic yarn as much as possible to ensure that the elastic yarn is in a stretched state and straightened, otherwise the measurement structure of the elastic yarn during detection will be affected, resulting in inaccurate measurement results. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a finished product detector for processing nylon elastic yarns, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A finished product detector for processing nylon elastic yarns, including a cabinet body, and an operating table is fixedly installed on the top of the cabinet body; A press, which is arranged on the top of the operating table, and the press is used to apply pressure to the elastic yarn; A detector, which is used to detect and record the parameters and data during the operation of the press; A fixing device is provided at the top of the cabinet body. The fixing device includes: a hollow cylinder, a collar, a pull rod, a threaded rod, a fixing plate and an arc plate. A chute is provided at the bottom of the inner wall of the operating table; A driving device, which is arranged on the inner wall of the chute and is used to drive itself to move on the inner wall of the chute; The hollow cylinder is fixedly installed on the top of the driving device. The collar is rotatably installed on the circumferential surface of the hollow cylinder. The pull rod is fixedly installed on the circumferential surface of the collar. The threaded rod is threadedly installed on the inner wall of the collar. The fixing plate is fixedly installed at one end of the threaded rod close to the collar. A first spring is arranged on the surface of the threaded rod. The arc plate is connected to the fixing plate through the first spring. The movement of the fixing device on the side away from the detector will drive the elastic wire to stretch and become taut, so that the elastic wire is fixed and straightened.

[0007] According to the above technical solution, the fixing device further includes: a triangular block, a telescopic rod and a connecting piece. There are two groups of fixing devices. The free end of the telescopic rod is fixedly installed on the circumferential surface of the driving device on the side away from the detector, and the fixed end of the telescopic rod is fixedly installed on the circumferential surface of the driving device on the side close to the detector. The triangular block is fixedly installed on the surface of the arc plate close to the fixing plate. A square groove is provided on the surface of the fixing plate close to the triangular block. The connecting piece is fixedly installed on the circumferential surface of the collar. After the arc plate is in close contact with the elastic wire, as the fixing plate continues to move, the triangular block will contact the square groove and be stuck into the inner wall of the square groove, so that when the elastic wire is under pressure, the arc plate cannot rotate upwards. A limiting device for fixing the fixing device and a protection device for protecting the operating fixing device are provided at the top of the cabinet body.

[0008] According to the above technical solution, the triangular block contacts the square groove, and the detector is electrically connected to the pressure machine, and the triangular block is limited by the square groove.

[0009] According to the above technical solution, the limiting device includes: a square box, a sliding block, a U-shaped rod, a one-way block, a sliding plate, a rotating block, a stop block and an inclined plane block. The square box is fixedly installed on the top of the operating table. The sliding block is slidably installed inside the square box. The U-shaped rod is fixedly installed on the surface of the sliding block. The one-way block is slidably installed on the top of the sliding block. A limiting groove is provided on the top of the square box. The sliding plate is slidably installed on the top of the operating table. A rotating groove is provided on the surface of the sliding plate close to each other. The rotating block is rotatably installed inside the rotating groove. The stop block is fixedly installed inside the rotating groove. The connecting piece moves and contacts the rotating block. The rotating block is blocked by the stop block so that the rotating block cannot move towards the direction of the pressure machine. The inclined plane block is fixedly installed on the surface of the sliding plate close to the square box. The movement of the sliding plate drives the rotating block to move away from the square box, and then the rotating block no longer blocks the connecting piece.

[0010] According to the above technical solution, the inclined plane block contacts the sliding block, and a first torsion spring is arranged between the rotating block and the sliding plate. When the rotating block no longer contacts the connecting part, the first torsion spring drives the rotating block to rotate towards the stop block.

[0011] According to the above technical solution, the protection device includes: a guide rail, a connecting plate, an air inflation cylinder, a sealing plate, a circular rod and a fixed ring. The guide rail is fixedly installed at the bottom of the inner wall of the operating table, the connecting plate is slidably installed on the top of the guide rail, the air inflation cylinder is fixedly installed on the top of the connecting plate, the sealing plate is slidably installed on the inner wall of the air inflation cylinder, a circular hole is formed on the circumferential surface of the air inflation cylinder, the fixed ring is rotatably installed on the circumferential surface of the driving device, one end of the circular rod is fixedly installed on the circumferential surface of the fixed ring, and the other end of the circular rod is fixedly installed on the surface of the sealing plate. The movement of the circular rod drives the sealing plate to move towards the inside of the air inflation cylinder and compress the air inside the air inflation cylinder. Since some of the circular holes are blocked by the arc-shaped baffle, the air can only be discharged through some of the circular holes.

[0012] According to the above technical solution, the protection device further includes: an L-shaped rod and an arc-shaped baffle. The L-shaped rod slidably penetrates through the inner and outer walls of the operating table. The L-shaped rod is fixedly installed at the bottom of the sliding plate, and the arc-shaped baffle is fixedly installed at the end of the L-shaped rod away from the sliding plate. The movement of the L-shaped rod drives the arc-shaped baffle to move away from the air inflation cylinder, and the arc-shaped baffle no longer contacts the air inflation cylinder after moving.

[0013] According to the above technical solution, the arc-shaped baffle contacts the circular hole, and a second spring is arranged between the sealing plate and the air inflation cylinder. The second spring drives the sealing plate to move towards the direction of the circular rod.

[0014] The present invention provides a finished product detector for processing polyamide elastic yarn. It has the following beneficial effects: (1) In this invention, the movement of the fixing device on the side away from the detector drives the elastic yarn to be stretched and straightened, so that the elastic yarn is fixed and straightened, preventing the elastic yarn from falling towards the bottom at the central position, which may cause the elastic yarn not to receive accurate pressure when the press applies pressure, resulting in inaccurate measurement results. This improves the reliability of the device measurement. After the arc-shaped plate is in close contact with the elastic yarn, as the fixing plate continues to move, the triangular block contacts and is stuck into the inner wall of the square groove, so that when the elastic yarn is under pressure, the arc-shaped plate cannot rotate upwards, increasing the friction between the arc-shaped plate and the elastic yarn, preventing the elastic yarn from sliding upwards after being under pressure, which affects the fixation of the elastic yarn, and ensuring the reliability and accuracy of the measurement results.

[0015] (2) In this invention, when the connecting piece moves, it will contact the rotating block. The rotating block is blocked by the stop block, preventing it from moving towards the direction of the press. This can prevent the fixing device from moving towards each other during the detection of the elastic wire, which may affect the measurement results. When the sliding plate moves, it drives the rotating block to move away from the square box. Subsequently, the rotating block no longer blocks the connecting piece, enabling the device to quickly release the limit on the fixing device after the detection is completed, and allowing other tests to be carried out again, thus improving the working efficiency of the device.

[0016] (3) In this invention, when the circular rod moves, it drives the sealing plate to move towards the inside of the inflating cylinder and squeeze the air inside the inflating cylinder. Since some circular holes are blocked by the arc-shaped baffle, the air can only be discharged through some circular holes, which limits the moving speed of the fixing device. As a result, the inertia of the fixing device is too large at the moment of stress release, leading to mutual collision between the devices and causing device damage. This improves the service life of the device. When the L-shaped rod moves, it drives the arc-shaped baffle to move away from the inflating cylinder. After the arc-shaped baffle moves, it no longer contacts the inflating cylinder, enabling the device to quickly reset without being restricted when the device is reset after the detection is completed, thus improving the practicality of the device.

Detailed implementation mode

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 6 , an embodiment of the present invention is: A finished product detector for the processing of polyamide elastic yarn, including a cabinet body 1, and an operating table 2 is fixedly installed on the top of the cabinet body 1; A press 4, the press 4 is arranged on the top of the operating table 2, and the press 4 is used to apply pressure to the elastic yarn; A detector 3, the detector 3 is used to detect and record the parameters and data during the operation of the press 4; A fixing device is arranged on the top of the cabinet body 1, and the fixing device includes: a hollow cylinder 52, a collar 53, a pull rod 54, a threaded rod 55, a fixing plate 56 and an arc plate 58, and a chute is opened at the bottom of the inner wall of the operating table 2; A driving device 51, the driving device 51 is arranged on the inner wall of the chute, and the driving device 51 is used to drive itself to move on the inner wall of the chute; The hollow cylinder 52 is fixedly installed on the top of the driving device 51, the collar 53 is rotatably installed on the circumferential surface of the hollow cylinder 52, the pull rod 54 is fixedly installed on the circumferential surface of the collar 53, the threaded rod 55 is threadedly installed on the inner wall of the collar 53, the fixing plate 56 is fixedly installed at one end of the threaded rod 55 close to the collar 53, a first spring 57 is arranged on the surface of the threaded rod 55, and the arc plate 58 is connected to the fixing plate 56 through the first spring 57, preventing the elastic yarn from falling downward at the center position, resulting in the elastic yarn not being able to receive accurate pressure when the press 4 applies pressure, leading to inaccurate measurement results, and improving the reliability of the device measurement.

[0021] The fixing device further includes: a triangular block 59, a telescopic rod 510, and a connecting member 511. There are two sets of fixing devices. The free end of the telescopic rod 510 is fixedly installed on the circumferential surface of the driving device 51 on the side away from the detector 3, and the fixed end of the telescopic rod 510 is fixedly installed on the circumferential surface of the driving device 51 on the side close to the detector 3. The triangular block 59 is fixedly installed on the surface of the arc-shaped plate 58 close to the fixing plate 56. A square groove is provided on the surface of the fixing plate 56 close to the triangular block 59. The connecting member 511 is fixedly installed on the circumferential surface of the collar 53, which increases the friction between the arc-shaped plate 58 and the elastic wire, prevents the elastic wire from sliding upward under pressure, affects the fixation of the elastic wire, and ensures the reliability and accuracy of the measurement results.

[0022] The triangular block 59 is in contact with the square groove, and the detector 3 is electrically connected to the press 4 to limit the triangular block 59 through the square groove.

[0023] During the operation of this embodiment: Place the two ends of the elastic wire to be detected inside the hollow cylinder 52, then push the pull rod 54 forward to rotate. The rotation of the pull rod 54 drives the rotation of the collar 53, and the rotation of the collar 53 drives the threaded rod 55 to move into the hollow cylinder 52. The movement of the threaded rod 55 drives the fixing plate 56 to move towards the elastic wire. The movement of the fixing plate 56 drives the first spring 57 and the arc-shaped plate 58 to move towards the elastic wire. The movement of the arc-shaped plate 58 will contact the elastic wire and fix the elastic wire. Then, the driving device 51 moves to drive the elastic wire to move towards the bottom of the press 4. Subsequently, the fixing device on the side away from the detector 3 continues to move away from the detector 3. The movement of the fixing device on the side away from the detector 3 will drive the elastic wire to be stretched and straightened, so that the elastic wire is fixed and straightened, preventing the elastic wire from falling to the bottom at the central position, resulting in inaccurate pressure on the elastic wire when the press 4 applies pressure and inaccurate measurement results, improving the reliability of the device measurement. After the arc-shaped plate 58 is in close contact with the elastic wire, as the fixing plate 56 continues to move, the triangular block 59 will contact the square groove and be stuck in the inner wall of the square groove, so that when the elastic wire is under pressure, the arc-shaped plate 58 cannot rotate upward, increasing the friction between the arc-shaped plate 58 and the elastic wire, preventing the elastic wire from sliding upward under pressure, affecting the fixation of the elastic wire, and ensuring the reliability and accuracy of the measurement results.

[0024] Please refer to Figures 1 - 9, on the basis of the above embodiments, in another embodiment of the present invention, a limiting device for fixing the fixing device and a protection device for protecting the operating fixing device are provided at the top of the cabinet body 1. Among them, the limiting device includes: a square box 61, a sliding block 62, a U-shaped rod 63, a one-way block 64, a sliding plate 65, a rotating block 66, a stop block 67, and an inclined block 68. The square box 61 is fixedly installed on the top of the operating table 2, the sliding block 62 is slidably installed inside the square box 61, the U-shaped rod 63 is fixedly installed on the surface of the sliding block 62, the one-way block 64 is slidably installed on the top of the sliding block 62, a limiting groove is opened on the top of the square box 61, the sliding plate 65 is slidably installed on the top of the operating table 2, a rotating groove is opened on the mutually approaching surfaces of the sliding plates 65, the rotating block 66 is rotatably installed on the inner wall of the rotating groove, and the stop block 67 is fixedly installed on the inner wall of the rotating groove to prevent the fixing device from moving in the mutually approaching direction during the detection of the elastic wire, resulting in the measurement result being affected. The inclined block 68 is fixedly installed on the surface of the sliding plate 65 close to the square box 61, so that after the device completes the detection, the device can quickly release the limit on the fixing device and can perform other tests again, improving the working efficiency of the device.

[0025] The inclined block 68 contacts the sliding block 62, and a first torsion spring is provided between the rotating block 66 and the sliding plate 65. When the rotating block 66 no longer contacts the connecting member 511, the first torsion spring drives the rotating block 66 to rotate towards the stop block 67.

[0026] The protection device includes: a guide rail 71, a connecting plate 72, an air cylinder 73, a sealing plate 74, a circular rod 75, and a fixed ring 76. The guide rail 71 is fixedly installed at the bottom of the inner wall of the operating table 2, the connecting plate 72 is slidably installed on the top of the guide rail 71, the air cylinder 73 is fixedly installed on the top of the connecting plate 72, the sealing plate 74 is slidably installed inside the air cylinder 73, a circular hole is opened on the circumferential surface of the air cylinder 73, the fixed ring 76 is rotatably installed on the circumferential surface of the driving device 51, one end of the circular rod 75 is fixedly installed on the circumferential surface of the fixed ring 76, and the other end of the circular rod 75 is fixedly installed on the surface of the sealing plate 74, so that the speed of the fixing device during movement is limited, resulting in too large inertia of the fixing device at the moment of stress release, causing the devices to collide with each other and damage the devices, thereby improving the service life of the devices.

[0027] The protection device further includes: an L-shaped rod 77 and an arc-shaped baffle 78. The L-shaped rod 77 slidably penetrates through the inner and outer walls of the operating table 2, the L-shaped rod 77 is fixedly installed at the bottom of the sliding plate 65, and the arc-shaped baffle 78 is fixedly installed at the end of the L-shaped rod 77 away from the sliding plate 65, so that the device will not be restricted during the reset after the device completes the detection, and can be quickly reset, improving the practicability of the device.

[0028] The arc-shaped baffle 78 contacts the round hole, and a second spring is provided between the sealing plate 74 and the inflating cylinder 73. The second spring drives the sealing plate 74 to move towards the direction of the round rod 75.

[0029] During the operation of this embodiment: The hollow cylinder 52 moves towards the direction of the square box 61, driving the connecting piece 511 to move towards the direction of the square box 61. The movement of the connecting piece 511 will contact the rotating block 66 and drive the rotating block 66 to rotate towards the direction of the square box 61. After the elastic wire is pressed by the press 4, the elastic wire drives the fixing device to move towards each other. The movement of the connecting piece 511 will contact the rotating block 66. The rotating block 66 is blocked by the stop block 67, making the rotating block 66 unable to move towards the direction of the press 4, preventing the fixing device from moving towards each other during the detection of the elastic wire, which may affect the measurement result. Push the U-shaped rod 63 towards the direction of the square box 61. The movement of the U-shaped rod 63 drives the one-way block 64 to move towards the direction of the limiting groove. After the one-way block 64 no longer contacts the square box 61, the one-way block 64 is limited by the limiting groove. The movement of the U-shaped rod 63 drives the sliding block 62 to move towards the direction of the inclined plane block 68. The movement of the sliding block 62 will contact the inclined plane block 68 and push the inclined plane block 68 to move away from the direction of the square box 61. The movement of the inclined plane block 68 drives the sliding plate 65 to move away from the fixing device. The movement of the sliding plate 65 drives the rotating block 66 to move away from the direction of the square box 61. Subsequently, the rotating block 66 no longer blocks the connecting piece 511, enabling the device to quickly release the limit on the fixing device after the detection is completed, and allowing other tests to be carried out again, improving the working efficiency of the device.

[0030] The driving device 51 moves to drive the fixed ring 76 to move, and the fixed ring 76 moves to drive the round rod 75 to move. Subsequently, after the detection of the elastic wire is completed, at the moment when the elastic wire breaks, due to the sudden release of stress, the fixing device will move away from each other in the state of being unidirectionally limited. Due to the release of stress, the fixing device moves away from each other rapidly. The movement of the round rod 75 drives the sealing plate 74 to move into the interior of the inflating cylinder 73 and squeeze the air inside the inflating cylinder 73. Since part of the round holes are blocked by the arc-shaped baffle 78, the air can only be discharged through part of the round holes, restricting the speed of the fixing device during movement. As a result, the inertia of the fixing device is too large at the moment of stress release, causing the devices to collide with each other and resulting in device damage, improving the service life of the device. The movement of the sliding plate 65 drives the L-shaped rod 77 to move away from the fixing device. The movement of the L-shaped rod 77 drives the arc-shaped baffle 78 to move away from the direction of the inflating cylinder 73. After the arc-shaped baffle 78 moves, it no longer contacts the inflating cylinder 73, enabling the device to be quickly reset without being restricted when the device is reset after the detection is completed, improving the practicality of the device.

[0031] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
