Description

Technical Field

[0001] The present invention belongs to the technical field related to the detection of knitted products, and specifically discloses an elastic measuring device for knitted product production. Background Art

[0002] Knitted products refer to textiles made through the knitting process, usually made of yarns through knitting machines or hand knitting. The structural feature of knitted products is that the coils are strung together with each other to form a fabric with good elasticity, softness and comfort;

[0003] An elastic measuring machine is a test device for detecting the stretching performance of knitted products themselves. During the production process of knitted products, it is necessary to use this elastic measuring machine to conduct an elastic test on the sample knitted products, and then detect whether this type of knitted products meets the national standards. The elastic measuring machine is composed of a measuring machine table, a tension sensor, a measuring ruler and a hook. Its principle is to detect the tension and stretching length borne by the knitted product through pulling and then use the tension sensor and the measuring ruler, and then obtain the elasticity possessed by the knitted product itself;

[0004] During the production process of knitted products, elastic measurement is required to ensure the production quality. For example, the Chinese invention patent discloses CN221007143U, an elastic measuring mechanism for knitted product production, including a measuring machine table and a tension sensor. A working chamber is arranged on the top of the measuring machine table, and a stretching mechanism is arranged inside the working chamber. The stretching mechanism includes a mounting block, which is slidably mounted on the rear side wall of the inner cavity of the working chamber. A limiting component is arranged on the back of the mounting block, and clamping frames are fixedly mounted on the bottom of the mounting block and the left side of the tension sensor. This elastic measuring mechanism for knitted product production realizes the stable clamping of both sides of the knitted product by using the clamping plate and the clamping frame through the setting of the stretching mechanism, so that when conducting the stretching elastic test, the knitted product will not slip off, which provides convenience for the elastic measurement of the knitted product, and can obtain accurate measurement values, and then ensures the evaluation of the elastic qualification rate of this type of knitted product;

[0005] Although the problem of the hook and clamping falling off is solved in the above document, in the actual detection process, the knitted product cannot be stretched in multiple directions, resulting in relatively thin detection data and being unable to be applied to the test of some special large-area knitted products, with great limitations. Therefore, we need to improve it. Summary of the Invention

[0006] The object of the present invention is to solve the problems existing in the background technology, and a device for measuring the elasticity of knitted products is proposed, including a detection table, on the upper surface of which a detection frame is vertically connected. A guide rail is connected to the outside of the detection frame through a fixed seat provided. Above and below the outside of the guide rail, a first elastic clamping table and a second elastic clamping table are respectively arranged. The first elastic clamping table is fixedly arranged below the outside of the guide rail, and the second elastic clamping table is slidably connected to the guide rail through a driving mechanism arranged outside. At both ends of the inner side of the mutually approaching sides of the first elastic clamping table and the second elastic clamping table, sliding rods are slidably installed. Clamping members are arranged at the ends of the two sliding rods. Tension mechanisms are arranged on both sides of the outer wall of the second elastic clamping table.

[0007] Preferably, the driving mechanism includes a sliding table fixedly arranged at the rear end outside the second elastic clamping table. The sliding table is slidably connected to the guide rail. A hydraulic cylinder is arranged above the sliding table. The telescopic end of the hydraulic cylinder is connected to the upper surface of the sliding table. The upper part outside the hydraulic cylinder is clamped inside the detection frame.

[0008] Preferably, the clamping member includes a connecting seat commonly installed at the ends of the two sliding rods. An abutting block is fixedly arranged on the inner surface of the connecting seat. Anti-slip strips are installed on the outer surface of the abutting block.

[0009] Preferably, on the outer edges of the sides of the first elastic clamping table and the second elastic clamping table away from the corresponding connecting seats, frames are fixedly arranged, and push cylinders are installed inside the frames. The telescopic ends of the push cylinders are fixedly connected to the surfaces of the connecting seats.

[0010] Preferably, the tension mechanism includes a side frame fixedly arranged on one side of the second elastic clamping table. A cross bar is arranged inside the side frame. A tension rope is arranged outside the cross bar.

[0011] Preferably, L-shaped frames are arranged on both sides of the detection frame. At the upper edge of one end of the L-shaped frame, a fixed block is fixedly arranged. A guide post is arranged on the outer surface of the fixed block. A pulley is rotatably installed on the outside of the guide post. A slider is slidably installed on the outside of the L-shaped frame. A clamping shaft is fixedly arranged on the outer surface of the slider. A rotating member is arranged outside the clamping shaft.

[0012] Preferably, the rotating member includes a clamping sleeve rotatably sleeved outside the clamping shaft. Connecting blocks are sleeved at both ends outside the clamping sleeve. A clamping frame is commonly installed on one side of the two groups of connecting blocks. A clamping member is arranged inside the clamping frame. A sleeve seat is fixedly arranged in the middle outside the clamping sleeve. A pin ring is fixedly arranged on the outside of the sleeve seat. A joint is arranged at one end of the pin ring away from the sleeve seat. The end of the tension rope away from the cross bar is wound around the outside of the pulley and the end is connected to the joint.

[0013] Preferably, the clamping member includes a fixed clamp fixedly arranged on one side inside the card frame, a cylinder is arranged on the inner side of the card frame and near the edge of the fixed clamp, a movable clamp is installed at the telescopic end of the cylinder, the movable clamp is slidably connected with the card frame, and anti-slip pads are arranged on the inner surfaces of the mutually approaching sides of the movable clamp and the fixed clamp.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Through the cooperation of the first elastic clamping platform and the second elastic clamping platform, the knitted fabric can be stably clamped to ensure the measurement accuracy. Moreover, with the drive of the pulling mechanism, the second elastic clamping platform can accurately control the stretching distance during detection, improving the measurement accuracy.

[0016] The hydraulic cylinder can be used to pull the second elastic clamping platform upward to stretch the knitted fabric fixed inside the first elastic clamping platform, thereby completing the vertical elastic stretching test. In addition, the sliding seat located on the L-shaped frame, with the automatic clamping of the cylinder, enables the fixed clamp and the movable clamp to clamp on both sides of the currently detected knitted fabric. When the hydraulic cylinder rises, the side frames on both sides of the second elastic clamping platform will drive the cross bar to move upward. At this time, since the L-shaped frame is fixedly connected to the detection frame, the tension rope outside the cross bar will slide on the outside of the pulley, pulling the sliding seat and the card frame to slide towards the end of the L-shaped frame, so as to perform elastic stretching at both ends of the knitted fabric, and realize vertical and horizontal stretching detection through this method. Through multi-directional elastic stretching, the detection quality of the detected knitted fabric is fully enhanced. Description of the Drawings

Detailed implementation mode

[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation modes.

[0026] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0027] As Figures 1-7 shown, an elastic measuring device for knitting production includes an inspection table 1. A vertically connected inspection frame 2 is arranged on the upper surface of the inspection table 1. A guide rail 13 is connected to the outside of the inspection frame 2 through a fixed seat 5 arranged thereon. A first elastic clamping table 6 and a second elastic clamping table 7 are respectively arranged above and below the outside of the guide rail 13. The first elastic clamping table 6 is fixedly arranged below the outside of the guide rail 13. The second elastic clamping table 7 is slidably connected to the guide rail 13 through a driving mechanism arranged outside. At both ends of the inner sides of the mutually close sides of the first elastic clamping table 6 and the second elastic clamping table 7, sliding rods 18 are slidably installed. Clamping members are arranged at the ends of the two sliding rods 18. Tension mechanisms are arranged on both sides of the outer wall of the second elastic clamping table 7;

[0028] The driving mechanism pulls the second elastic clamping table 7 to move upward, so that it cooperates with the fixedly arranged first elastic clamping table 6 to realize the stretching detection of the knitting inspection object;

[0029] The setting of the sliding rod 18 mainly enhances the stability of the clamping member during movement.

[0030] The driving mechanism includes a sliding table 4 fixedly arranged at the rear end outside the second elastic clamping table 7. The sliding table 4 is slidably connected to the guide rail 13. A hydraulic cylinder 3 is arranged above the sliding table 4. The telescopic end of the hydraulic cylinder 3 is connected to the upper surface of the sliding table 4. The upper part outside the hydraulic cylinder 3 is clamped inside the inspection frame 2;

[0031] The hydraulic cylinder 3 drives the sliding table 4 to rise, so that the second elastic clamping table 7 can stretch one end of the knitting inspection object.

[0032] The clamping member includes a connecting seat 17 commonly installed at the ends of two sliding rods 18. An abutting block 31 is fixedly arranged on the inner surface of the connecting seat 17, and an anti-slip strip 32 is installed on the outer surface of the abutting block 31;

[0033] The abutting block 31 is applicable to large-area detection objects, and the anti-slip strip 32 can reduce the risk of the knitted fabric slipping during clamping.

[0034] On the outer edges of the sides of the first elastic clamping platform 6 and the second elastic clamping platform 7 away from the corresponding connecting seats 17, frames 8 are fixedly arranged, and push cylinders 14 are installed inside the frames 8. The telescopic ends of the push cylinders 14 are fixedly connected to the surfaces of the connecting seats 17;

[0035] Driven by the push cylinder 14, it can cause the corresponding connecting seat 17 and abutting block 31 to move away from the corresponding first elastic clamping platform 6 and second elastic clamping platform 7, so as to facilitate the placement of the knitted fabric detection object for detection.

[0036] The tension mechanism includes a side frame 15 fixedly arranged on one side of the second elastic clamping platform 7. A cross bar 25 is arranged inside the side frame 15, and a tension rope 11 is arranged outside the cross bar 25;

[0037] The side frame 15 can stably support the internal cross bar 25 above one end of the moving second elastic clamping platform 7, so as to meet the pulling and guiding of the tension rope 11.

[0038] L-shaped frames 10 are arranged on both sides of the detection frame 2. At the upper edge of one end of the L-shaped frame 10, a fixing block 12 is fixedly arranged. A guide post 16 is arranged on the outer surface of the fixing block 12. A pulley 9 is rotatably installed outside the guide post 16. A slider 19 is slidably installed outside the L-shaped frame 10. A clamping shaft 20 is fixedly arranged on the outer surface of the slider 19, and a rotating member is arranged outside the clamping shaft 20;

[0039] Through the arranged guide post 16, the pulley 9 can be stably arranged at the edge of one end of the L-shaped frame 10, and the pulley 9 reduces the friction when the tension rope 11 is pulled.

[0040] The rotating member includes a clamping sleeve 26 rotatably sleeved outside the clamping shaft 20. Connecting blocks 29 are sleeved on both outer ends of the clamping sleeve 26. A clamping frame 21 is commonly installed on one side of the two groups of connecting blocks 29. A clamping member is arranged inside the clamping frame 21. A socket 27 is fixedly arranged in the middle outside the clamping sleeve 26. A pin ring 28 is fixedly arranged on the outside of the socket 27. A joint 24 is arranged at one end of the pin ring 28 away from the socket 27. The end of the tension rope 11 away from the cross bar 25 is wound outside the pulley 9 and the end is connected to the joint 24;

[0041] When the second elastic clamping table 7 moves upward, the tension rope 11 outside the cross bar 25 will, under the sliding and clamping of the pulley 9, pull the slider 19 towards the end of the L-shaped frame 10. At this time, the slider 19 will drive the clamping frame 21, the clamping shaft 20, and the connecting block 29 to move. At this time, the clamping member can horizontally pull the knitted fabric test object towards one end, thereby detecting multi-directional elastic data;

[0042] The joint 24 is used to connect the pin ring 28 and the tension rope 11. When the tension rope 11 moves, it will pull the clamping shaft 20 and the slider 19 to move.

[0043] The clamping member includes a fixed clamp 23 fixedly arranged on one side inside the clamping frame 21. A cylinder 30 is arranged inside the clamping frame 21 and near the edge of the fixed clamp 23. The telescopic end of the cylinder 30 is provided with a movable clamp 22. The movable clamp 22 is slidably connected to the clamping frame 21. Anti-slip pads are arranged on the inner surfaces of the mutually approaching sides of the movable clamp 22 and the fixed clamp 23;

[0044] After the knitted fabric test object is vertically clamped inside the first elastic clamping table 6 and the second elastic clamping table 7, the cylinder 30 drives the movable clamp 22 to approach the fixed clamp 23, and then the two sides of the knitted fabric test object can be horizontally clamped. At this time, the knitted fabric test object is fixed both vertically and horizontally. When the second elastic clamping table 7 moves upward subsequently, the knitted fabric test object is simultaneously horizontally pulled, thereby realizing multi-directional pulling elastic detection.

[0045] Working principle: During detection, the push cylinders 14 at the first elastic clamping table 6 and the second elastic clamping table 7 drive the connecting seat 17 and the abutting block 31 to move, so that the abutting block 31 moves away from the inner surfaces of the corresponding first elastic clamping table 6 and the second elastic clamping table 7. Then, the tested knitted fabric test object is respectively clamped between the first elastic clamping table 6 and the corresponding abutting block 31, and the second elastic clamping table 7 and the corresponding abutting block 31. The two ends of the knitted fabric test object are automatically driven by the cylinder 30 at the clamping frame 21 to make the movable clamp 22 close to the inner surface of the fixed clamp 23 against the knitted fabric test object, completing the horizontal and vertical fixation of the knitted fabric test object;

[0046] Subsequently, the hydraulic cylinder 3 drives the slide table 4 to move upward, causing the slide table 4 to move outside the guide rail 13. During the movement, the knitted fabric test object is gradually tensioned. As the slide table 4 gradually rises, the external detection program monitors the stretching length and the tensile force of the knitted fabric in real time, records the elastic data, and when the hydraulic cylinder 3 drives the second elastic clamping table 7 to move, the side frames 15 on both sides of the second elastic clamping table 7 will drive the inner cross bar 25 to move upward. Since the L-shaped frame 10 is fixedly connected to the detection frame 2, the tension ropes 11 outside the cross bar 25 will slide outside the pulley 9, and by virtue of the traction force, the slider 19 and the clamping frame 21 are pulled towards the end of the L-shaped frame 10. At this time, the knitted fabric test object clamped between the fixed clamp 23 and the movable clamp 22 will be elastically stretched at both ends of the knitted fabric under the horizontal movement track, and the vertical and horizontal lifting detections are realized in this way. Through the multi-directional elastic lifting, the detection quality of the knitted fabric is fully enhanced.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
