Description

Technical Field

[0001] The invention belongs to the technical field of yarn testing, and in particular relates to a semi-automatic yarn changing device of a yarn testing device. Background Art

[0002] Yarn is a textile that is processed into products of a certain fineness from various textile fibers and is used for weaving, rope making, thread making, knitting and embroidery, etc. It is divided into short-staple yarn, continuous filament, etc. During the production process of yarn for clothing fabrics, in order to ensure the quality of clothing fabrics, etc., the yarn used in clothing needs to be subjected to tensile testing so that the clothing fabrics made from it have good tensile resistance under use and avoid phenomena such as breakage and detachment of clothing. Modern tensile testing devices have many functions. In order to improve the testing efficiency of yarns, different types of yarns are tested on the same testing equipment to ensure the efficiency of yarn testing. When testing multiple yarns of different types on the testing equipment, a line changing device is used to change the line on the testing equipment, and semi-automatic testing is achieved with manual operation to increase the testing speed.

[0003] However, the existing semi-automatic yarn conversion equipment for yarn testing has the following disadvantages during use:

[0004] 1. The operation is cumbersome and inefficient. In the process of fixing and tightening multiple yarns, the existing semi-automatic yarn changing equipment requires staff to manually pass each yarn through the thread-holding device on the testing equipment and fix it. This process involves multiple tedious steps, which not only requires threading the yarn, but also requires careful adjustment of the yarn's fixed position and tightness. Since the entire process relies entirely on manual operation, staff need to spend a lot of time and energy to ensure that each yarn can be accurately and firmly fixed on the thread-holding device. This not only greatly affects the efficiency of yarn testing, making the entire testing process time-consuming, but also increases the workload of staff, easily leading to staff fatigue, and thus affecting the accuracy and stability of subsequent operations;

[0005] 2. Lack of reinforcement function, low detection accuracy. In the existing yarn tensile test process, although the yarn is changed once through the semi-automatic line changing equipment to achieve the detection, but during the detection process, only rely on the fixing components on the line changing equipment to fix the two ends of the yarn to be tested. Since the equipment is in a state of constant movement during the line changing process, this simple fixing method can easily cause the yarn to loosen. Once the yarn becomes loose during the detection process, it will not only cause the failure of this test, but also require re-fixation and re-testing, wasting time and resources, and will also affect the accuracy of the subsequent tensile test. Ordinary line changing equipment lacks effective reinforcement function and cannot guarantee the stability of the yarn during the detection process, thereby reducing the accuracy and reliability of yarn detection, and cannot provide strong data support for yarn quality control;

[0006] 3. Inconvenient operation and poor equipment convenience. Although conventional yarn testing equipment is equipped with a thread-changing device for testing different yarns, in actual operation, the staff must manually adjust the tensile testing equipment to hook it onto the yarn to be tested. Due to the limited space in the yarn testing area, the staff's operating space is small and their vision is obstructed when making manual adjustments, making it difficult to accurately and quickly complete the connection and locking operation between the tensile testing equipment and the yarn to be tested. This not only increases the difficulty and complexity of operation and reduces the convenience of equipment use, but also easily leads to operational errors, affecting the smooth progress of the test.

[0007] Therefore, it is necessary to invent a semi-automatic yarn conversion device of a yarn testing device to solve the above problems. Summary of the Invention

[0020] The technical effects and advantages of the present invention are as follows:

[0021] 1. The present invention provides a yarn changing mechanism and a wire assembly. The wire assembly automatically guides each yarn to be tested onto the connecting frame and locks its two ends by pushing the fixed block through the lifting bracket. Then, the position of the yarn is adjusted by sliding the movable base in the first limiting slide. The first electric push rod pushes the connecting frame and the fixed frame to adjust the position of the yarn in turn, so that the yarn passes through the area to be tested for tensile strength testing. During the whole process, there is no need for manual operations such as threading, fixing, and position adjustment by the staff, which reduces the time spent on yarn testing, improves the testing efficiency, and reduces the workload of the staff.

[0022] 2. The present invention provides a fixing component. After adjusting the position of the yarn, the rotating frame is rotated to place the limit frame above the yarn. When the yarn to be tested is changed in sequence, the third electric push rod is intermittently started on the limit frame, so that the gasket below is pressed against the lifting brackets at both ends of the yarn to be tested in sequence, further reinforcing the two ends of the yarn to be tested, preventing it from falling off due to insufficient fixation during tensile strength testing, thereby improving the test accuracy of the device;

[0023] 3. The present invention is provided with a yarn testing mechanism. After the yarn is changed, the fourth electric push rod is started to push the mounting frame up so that the yarn to be tested is located inside the arc-shaped clamp, and then the fourth motor is started to drive the gear to rotate and engage with the tooth groove in the middle of the arc-shaped clamp, and the arc-shaped clamp is rotated on the top of the mounting frame. During rotation, the limit sliders at both ends of the top of the mounting frame slide in the fourth limit slide groove and are limited so that the arc-shaped clamp cannot be separated from the mounting frame. After the arc-shaped clamp is rotated so that the clamping end faces the side, the fourth electric push rod is started to pull the mounting frame down with the arc-shaped clamp, thereby pulling the yarn. At this time, the yarn is squeezed on the pressure sensor on the side of the inner wall of the arc-shaped clamp. When subjected to tension, the pressure sensor transmits data to the intelligent control panel for analysis and processing. The test can be stopped until the yarn is broken or the tension reaches a certain range. Then the arc-shaped clamp is rotated so that its open end faces upward, which facilitates the next changed yarn to be clamped in for testing. There is no need for the staff to repeatedly adjust the position and fixed state of the yarn in sequence, thereby improving the convenience of using the device.

[0039] The yarn conversion mechanism 2 includes a first limiting slide 201 provided on one side of the top of the detection platform 1, the inner wall of the first limiting slide 201 is slidably connected to the movable base 202, a support frame 203 is provided on one side of the movable base 202, and a slide bar 204 is fixed at both ends of one side of the support frame 203, a connecting frame 205 is installed between the outer walls of the two slide bars 204, a fixing frame 206 is fixed at the middle position of one side of the top of the connecting frame 205, a plurality of wire grooves 207 are equidistantly provided at both ends of the top of the connecting frame 205, a small hydraulic cylinder 208 is installed on one side of the top of the fixing frame 206, and the output end of the small hydraulic cylinder 208 passes through the fixed A connecting shaft 209 is inserted and connected to the bottom of the fixed frame 206. A lifting bracket 210 is fixed to the bottom of the connecting shaft 209. A plurality of fixed blocks 211 are fixed at equal distances on both sides of the top of the lifting bracket 210, and the outer wall of each fixed block 211 is respectively inserted and connected to the inner wall of each wire groove 207. A first electric push rod 212 is installed on one side of the support frame 203, and the output end of the first electric push rod 212 is fixedly connected to one side of the fixed frame 206. Second limiting sliding grooves 213 are opened on both sides of the connecting frame 205, and the outer walls of the two slide bars 204 are respectively slidably connected to the inner walls of the two second limiting sliding grooves 213;

[0040] When in use, start the third motor 5 to rotate the screw 216 to drive the movable base 202 to slide in the first limiting slide 201 to move it to one end of the top of the detection platform 1, and then start the second electric push rod 215 to push the support frame 203 to slide in the third limiting slide 214 to push the yarn conversion mechanism 2 to drop pressure, so that the two ends of the connecting frame 205 on it are respectively stuck on both sides of the docking groove 217, so that they are tightly docked, so that the wire grooves 207 at both ends of the connecting frame 205 are connected and aligned with the inner walls of the two ends of the docking groove 217. At this time, each yarn to be tested is rotated and squeezed into the wire groove 207 at one end of the connecting frame 205 through the wire assembly 3, and then the wire groove 207 at one end is transferred through the inside of the docking groove 217 to guide one end of the yarn into each wire groove 207 at the other end of the connecting frame 205, and then the small hydraulic cylinder 208 on the top of the fixed frame 206 is started to push the connecting shaft 209 to squeeze The lifting bracket 210 above the connecting frame 205 is pressed, so that the fixed blocks 211 at the two ends of the bottom of the lifting bracket 210 are respectively inserted into the wire grooves 207 at both ends to squeeze and fix the two ends of the yarn pulled into the wire grooves 207 at both ends, and then the mechanism is moved and adjusted to the other side of the detection top by rotating the screw 216 and starting the second electric push rod 215. During the detection process, the fixed yarn is pulled by the tension testing mechanism 8 for detection, and during the detection process, the first electric push rod 212 is started to push the connecting frame 205. The connecting frame 205 slides on the outer wall of the slide bar 204 through the second limiting slide grooves 213 on both sides, and then changes its position in turn above the tension testing mechanism 8 for tension testing. During the whole process, there is no need for the staff to manually perform operations such as threading, fixing and position adjustment, which reduces the time spent on yarn testing, improves testing efficiency, and reduces the workload of the staff.

[0041] The two ends of one side of the movable base 202 are provided with a third limiting slide groove 214, and the outer walls of the two ends of the support frame 203 are respectively slidably connected to the inner walls of the two third limiting slide grooves 214, and the bottoms of the inner walls of the two third limiting slide grooves 214 are respectively installed with second electric push rods 215, and the output ends of the two second electric push rods 215 are respectively fixedly connected to the bottom of the support frame 203, the inner wall of the first limiting slide groove 201 is rotatably connected with a screw rod 216, and the outer wall of the screw rod 216 is threadedly connected to the inner wall of the movable base 202, and the detection platform 1. A plurality of docking grooves 217 are installed at equal distances on one side of the top. The second electric push rod 215 pushes the support frame 203 to drive the entire yarn conversion mechanism 2 to be raised and lowered on the movable base 202. Then, the screw 216 is rotated to drive the movable base 202 to slide in the first limiting slide 201 to adjust the position of the converted yarn. In the threading process, the connecting frame 205 is moved to one side of the top of the detection table 1 so that the outer walls at both ends are respectively docked on both sides of the docking groove 217 to make them connected, so as to facilitate the insertion of the yarn.

[0042] Further, as the instructions Figure 6 As shown, the wire assembly 3 includes an adjusting frame 301 rotatably connected to both sides of one end of the connecting frame 205, and a rotating shaft 302 is rotatably connected between the two adjusting frames 301. The outer wall of the rotating shaft 302 is fixedly provided with a first wire wheel 303 at equal distances, wherein one end of the inner wall of multiple wire grooves 207 is rotatably connected to a second wire wheel 304. The staff passes each yarn through the corresponding wire groove 207, starts the second motor 307 to rotate the rotating shaft 302, and then rotates with the first wire wheel 303. When the yarn is squeezed, the second wire wheel 304 below rotates together. Under the mutual rotation and squeezing of the two, the yarn is transferred into the docking groove 217 until one end loses the squeezing of the two. At this time, the two ends of the yarn are just located in the wire grooves 207 at both ends. The yarn conversion mechanism 2 is raised to take the fixed yarn out of the docking groove 217.

[0043] An installation slot 305 is provided on the inner wall of one end of the connecting frame 205, and a first motor 306 is installed on the inner wall of the installation slot 305, and one end of one of the adjusting frames 301 is fixedly connected to the output end of the first motor 306, and a second motor 307 is installed on one side of the other end of one of the adjusting frames 301, and one end of the rotating shaft 302 is fixedly connected to the output end of the second motor 307.

If multiple yarns of different diameters are encountered, the gap can be adjusted and the corresponding yarn can be pulled to avoid damage to the yarn due to excessive squeezing, which in turn affects the subsequent tensile strength test.

[0044] Further, as the instructions Figure 7 As shown, the fixing component 4 includes two first connecting grooves 401 opened at one end of the top of the detection platform 1, the inner walls of the two first connecting grooves 401 are rotatably connected to the rotating frame 402, one end of the two rotating frames 402 is inserted and connected to the limiting frame 403, the outer walls of both ends of the limiting frame 403 are sleeved with springs 404, and the two ends of the two springs 404 are respectively fixedly connected to one end of the two rotating frames 402 and the two ends of the limiting frame 403, and the fixing component 4 is rotated in the first connecting groove 401 through the two rotating frames 402, so that it can be rotated open when the position of the yarn is adjusted to avoid obstructing the operation of the equipment.

During sequential detection, the gaskets 408 at the bottom of the third electric push rods 407 on both sides of the limiting frame 403 are just above the fixed blocks 211 at both ends of the yarn to be detected. The third electric push rods 407 are started to push the gaskets 408 to squeeze the two sides of the lifting bracket 210 above the fixed block 211, thereby further fixing the two ends of the yarn to be detected, so that the two ends are not easy to fall off during detection, thereby reducing the impact on the yarn tensile strength detection and improving the detection quality;

[0046] Furthermore, a third motor 5 is installed at one end of the outer wall of the testing platform 1, and one end of the screw 216 is fixedly connected to the output end of the third motor 5. An intelligent control panel 6 is installed on one side of the testing platform 1. A detection slot 7 is provided on the other side of the top of the testing platform 1 between two limit blocks 409. All electrical devices on the device are controlled and adjusted through the intelligent control panel 6. The intelligent control panel 6 is intelligent and can analyze and record the yarn tension data of the pressure sensor 809.

[0047] Further, as the instructions Figure 8-10 As shown, the tension testing mechanism 8 includes a fourth electric push rod 801 provided in the inner wall of the detection groove 7, and a mounting bracket 802 is fixedly provided at the output end of the fourth electric push rod 801, and limit sliders 803 are fixedly provided on both sides of the top of the mounting bracket 802, and an arc-shaped clamp 804 is sleeved between the outer walls of the two limit sliders 803, and fourth limit slide grooves 805 are provided on both sides of the outer wall of the arc clamp 804, and the outer walls of the two limit sliders 803 are respectively slidably connected to the inner walls of the two fourth limit slide grooves 805, and the yarn to be tested is pushed by the yarn changing mechanism 2 so that it passes over the top of the arc clamp 804 in turn, and each time the yarn is changed, the arc clamp 804 is lowered to the inside of the detection groove 7 so that it is located below the yarn to avoid hindering the movement and change of the yarn, and during the change and adjustment, the open ends of the arc clamps 804 are facing upwards, which is convenient for clamping the yarn therein.

[0048] A tooth groove 806 is provided in the middle position of the outer wall of the arc-shaped clamp 804, and a second connecting groove 807 is provided in the middle position of the mounting frame 802.

A pressure sensor 809 is installed on one side of the inner wall of the arc-shaped clamp 804, and one end of the gear 808 passes through the outer wall of one side of the mounting frame 802 and is connected to the fourth motor 810. After the yarn is changed, the fourth electric push rod 801 is started to push the mounting frame 802 to rise, so that the yarn to be detected is located inside the arc-shaped clamp 804, and then the fourth motor 810 is started to drive the gear 808 to rotate and mesh with the tooth groove 806 in the middle of the arc-shaped clamp 804, and the arc-shaped clamp 804 rotates on the top of the mounting frame 802. During rotation, the limit switches at both ends of the top of the mounting frame 802 The positioning slider 803 slides in the fourth limiting slot 805 and is limited, so that the arc clamp 804 cannot separate from the mounting bracket 802. After the arc clamp 804 is rotated so that the clamping end faces the side, the fourth electric push rod 801 is started, and the mounting bracket 802 is pulled down with the arc clamp 804, thereby pulling the yarn. At this time, the yarn is squeezed on the pressure sensor 809 on the side of the inner wall of the arc clamp 804. When subjected to tension, the pressure sensor 809 transmits data to the intelligent control panel 6 for analysis and processing until the yarn is broken or the tension reaches a certain range, the test can be stopped, and then the arc clamp 804 is rotated so that its open end faces upward, so that the next yarn to be changed can be clamped in for testing. There is no need for staff to repeatedly adjust the position and fixed state of the yarn in sequence, thereby improving the convenience of using the device.
