Description

Technical Field

[0001] This utility model relates to the field of yarn fixing technology, specifically a single yarn strength machine that facilitates yarn fixing. Background Technology

[0002] Textile machines twist many plant and animal fibers together to spin them into threads or yarns, which can be used to weave cloth. Single yarn strength testers are used to test the breaking strength and breaking elongation of various cotton, wool, linen, chemical fiber, pure spun, and rolled yarns. In yarn production, a single yarn strength tester that can easily fix the yarn is needed.

[0003] Application number CN202321630214.8 discloses a single yarn strength tester for easy yarn fixing, belonging to the field of textile testing technology. It includes a base, with a body mounted on the upper surface of the base. The body contains a testing mechanism and a fixing mechanism. The testing mechanism includes a rotating shaft rotatably mounted within the body, with gears mounted on the outer surface of the shaft. Two racks are mounted within the body, facing each other and meshing with the gears. L-shaped connecting rods are mounted on the racks. Two sliding holes for the L-shaped connecting rods are provided on the body. A motor is included; when the motor starts, it drives the rotating shaft to rotate. The rotation of the shaft, through the transmission action of the gears and racks, drives the L-shaped connecting rods and sliders to move. The movement of the sliders causes two fixing seats to move relative to each other. This relative movement of the fixing seats synchronously stretches both ends of the yarn, ensuring even force distribution at both ends and improving the accuracy of the test results.

[0004] During use, the fixing mechanism of this single yarn strength tester only stretches the two ends of the yarn through the relative movement of the fixing seats. It does not have an adjustment structure designed for the yarn width direction. When dealing with yarns of different widths, the spacing or opening size of the fixing seats cannot be flexibly adjusted. For wider or narrower yarns, the fixing may not be secure or effective, which limits the adaptability of the equipment to yarns of different specifications and cannot meet the diverse textile testing needs. Utility Model Content

[0005] The purpose of this invention is to provide a single yarn strength tester that facilitates the fixing of yarns and solves the problem of not being able to adapt to yarns of different specifications.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a single yarn strength machine that facilitates yarn fixation, including a strong stretching component and a shrinking component. The shrinking component is installed on the inner walls of the bottom two sides of the strong stretching component. The strong stretching component includes a set of bases. The shrinking component includes two sets of bearing seats. A rotating shaft and a roller limiting sleeve are respectively installed on the side of the bearing seats on the left and right sides that are close to each other. The rotating shaft is slidably connected to the inner wall of the roller limiting sleeve. Telescopic rods are installed on the inner walls of the two sides of the set of bases. A drive motor is installed on the outer wall of the right base. One end of the telescopic rod passes through the base and is connected to the drive motor. The purpose of this setup is that, during the use of this single yarn strength tester, according to yarn testing requirements, rotating the manual wheel at the top of the low frame rod drives the first set of screw stepping components to rotate, causing the sliding sleeve to slide up and down on the low frame rod to adjust the height of the bearing seat on that side; simultaneously, starting the motor at the top of the high frame rod drives the second set of screw stepping components, causing the sliding sleeve to slide up and down on the high frame rod to adjust the height of the bearing seat on that side; after adjustment, rotating the locking screw so that its tail end abuts against the outer wall of the bearing seat, firmly locking the bearing seat in the mounting groove of the sliding sleeve, ensuring the stability of the shrinkage component position, and starting the drive motor on the outer wall of the right base, the drive motor drives the telescopic rod to operate, the telescopic rod penetrating the base. Power is transmitted, causing the rotating shaft to slide within the inner wall of the roller limiting sleeve. This initiates the shrinking assembly's operation, shrinking or adjusting the yarn's position. Based on this yarn adjustment by the shrinking assembly, the high-strength stretching assembly works in conjunction, continuously providing power through the drive motor to stretch the yarn and perform single-yarn strength tests. The connection between the drive motor and the telescopic rod allows the motor to directly move the telescopic rod, providing stable power to the shrinking assembly and ensuring smooth yarn shrinking operations, thus improving equipment efficiency. The sliding connection between the rotating shaft and the roller limiting sleeve makes the internal structure of the shrinking assembly more flexible during operation, adapting to the shrinking needs of different yarn specifications and enhancing the equipment's adaptability to various yarn types.

[0008] Furthermore, a low frame rod and a high frame rod are respectively connected to both sides of the adjacent sides of the set of bases, and the telescopic rod is located between the low frame rod and the high frame rod. The purpose of this arrangement is that during the use of this single yarn strength tester, the low frame rod and the high frame rod are fixed to the adjacent sides of the set of bases to form a support structure. The telescopic rod is located between the low frame rod and the high frame rod, and when it operates under the drive motor, the low and high frame rods provide lateral support and guidance, ensuring the stable operation of the telescopic rod and its connected components.

[0009] Furthermore, sliding sleeves are slidably connected to the inner walls of both sides of the low and high frame rods. Mounting grooves are formed on the outer wall of the top side of the sliding sleeves that are close to each other on both sides. Two sets of bearing seats are rotatably connected within the mounting grooves of the two sets of sliding sleeves. The purpose of this arrangement is that, during the use of this single-yarn strength machine, the sliding sleeves slide along the inner walls of both sides of the low and high frame rods. When the position of the shrinkage assembly needs to be adjusted, the sliding sleeves move, and the bearing seats rotatably connected within their mounting grooves change position accordingly, thereby adjusting the lateral position of components such as the rotating shaft and roller limit sleeves to adapt to different yarn fixing requirements.

[0010] Furthermore, manual rollers are rotatably connected to the inner walls of the top two sides of the low frame rod. A first set of lead screw stepping assemblies is mounted at the bottom of each manual roller, extending downwards to the bottom of a sliding sleeve. The sliding sleeve is mounted on the outer wall of the first set of lead screw stepping assemblies. This arrangement allows the manual rollers on both sides of the top of the low frame rod to rotate during operation, driving the first set of lead screw stepping assemblies to rotate downwards. The sliding sleeve, mounted on the outer wall of the lead screw, slides up and down along the lead screw as it rotates, enabling precise manual adjustment of the vertical position of the sliding sleeve on the low frame rod, thereby adjusting the height of the bearing seat and the shrinkage assembly.

[0011] Furthermore, motors are installed on the outer walls of the top two sides of the high-frame rod, and a second set of lead screw stepping assemblies is installed at the bottom of the motors. These second set of lead screw stepping assemblies extends through the high-frame rod to the bottom of the sliding sleeve. The purpose of this arrangement is that during the use of the single-yarn strength tester, the motors on the top two sides of the high-frame rod are activated, driving the second set of lead screw stepping assemblies to operate. The lead screw stepping assemblies extend through the high-frame rod to the bottom of the sliding sleeve. The sliding sleeve slides up and down with the rotation of the lead screw, achieving automated and precise adjustment of the vertical position of the sliding sleeve on the high-frame rod, accurately adjusting the height of the shrinkage assembly, and meeting the needs of different testing scenarios.

[0012] Furthermore, a locking screw is threaded onto one inner wall of the sliding sleeve, with its tail end extending through to the mounting groove and abutting against one outer wall of the bearing housing. This arrangement is intended to ensure that, during operation of the single-yarn strength tester, after the sliding sleeve has adjusted the bearing housing to a suitable position, the locking screw is rotated, allowing its tail end to extend through the inner wall of the sliding sleeve into the mounting groove. The locking screw is then gradually tightened until its tail end presses against one outer wall of the bearing housing, firmly locking the bearing housing within the mounting groove of the sliding sleeve. This prevents displacement of the bearing housing during operation and ensures stable operation of the shrinkage assembly.

[0013] This utility model has the following beneficial effects:

[0014] (1) This utility model, through the setting of drive motor, rotating shaft and roller limiting sleeve, and the connection between drive motor and telescopic rod, the operation of drive motor can directly drive telescopic rod to move, providing stable power for shrinking component. The rotating shaft and roller limiting sleeve are slidably connected, making the internal structure of shrinking component more flexible during operation, adapting to the shrinking needs of yarns of different specifications, and enhancing the equipment's adaptability to various yarns.

[0015] (2) By setting up a locking screw and a sliding sleeve block, when the sliding sleeve block drives the bearing seat to adjust to a suitable position, the locking screw is rotated so that its tail end extends through the inner wall of the sliding sleeve block into the mounting groove. The locking screw is gradually tightened so that its tail end abuts against the outer wall of one side of the bearing seat, and the bearing seat is firmly locked in the mounting groove of the sliding sleeve block to prevent the bearing seat from shifting during operation and to ensure the stable operation of the shrink assembly.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 As shown, this utility model is a single yarn strength machine that facilitates the fixing of yarn, including a strong stretching component 1 and a shrinking component 2. The shrinking component 2 is installed on the inner walls of the bottom two sides of the strong stretching component 1. The strong stretching component 1 includes a set of bases 101. The shrinking component 2 includes two sets of bearing seats 203. A rotating shaft 204 and a roller limiting sleeve 205 are respectively installed on the side of the left and right bearing seats 203 that are close to each other. The rotating shaft 204 is slidably connected to the inner wall of the roller limiting sleeve 205. Telescopic rods 202 are installed on the inner walls of the two sides of the set of bases 101. A drive motor 201 is installed on the outer wall of the right base 101. One end of the telescopic rod 202 passes through the base 101 and is connected to the drive motor 201. The purpose of this setup is that, during the use of the single yarn strength tester, according to the yarn testing requirements, the manual rotary wheel 109 at the top of the low frame rod 102 is rotated to drive the first set of lead screw stepping components 107 to rotate, causing the sliding sleeve 104 to slide up and down on the low frame rod 102 to adjust the height of the bearing seat 203 on that side; simultaneously, the motor 108 at the top of the high frame rod 103 is started to drive the second set of lead screw stepping components 107, causing the sliding sleeve 104 to slide up and down on the high frame rod 103 to adjust the height of the bearing seat 203 on that side; after adjustment, the locking screw 105 is rotated so that its tail end abuts against the outer wall of the bearing seat 203, firmly locking the bearing seat 203 in the mounting groove 106 of the sliding sleeve 104, ensuring the stability of the shrinkage component 2, and the drive motor 201 on the outer wall of the right base 101 is started, the drive motor 201 drives When the telescopic rod 202 operates, it transmits power through the base 101, causing the rotating shaft 204 to slide on the inner wall of the roller limiting sleeve 205. The shrinking component 2 then begins to work, shrinking or adjusting the position of the yarn. Based on the yarn adjustment by the shrinking component 2, the high-strength stretching component 1 works in conjunction, continuously providing power through the drive motor 201 to achieve operations such as yarn stretching and complete the single yarn strength test. Through the connection between the drive motor 201 and the telescopic rod 202, the operation of the drive motor can directly drive the telescopic rod to move, providing stable power to the shrinking component 2, ensuring smooth yarn shrinking and other operations, and improving the working efficiency of the equipment. The sliding connection between the rotating shaft 204 and the roller limiting sleeve 205 makes the internal structure of the shrinking component more flexible during operation, adapting to the shrinking needs of different specifications of yarn and enhancing the equipment's adaptability to various yarns.

[0026] A set of bases 101 has a low frame rod 102 and a high frame rod 103 connected to its two adjacent sides, with a telescopic rod 202 positioned between them. This arrangement ensures that, during operation of the single yarn strength tester, the low frame rod 102 and the high frame rod 103 are fixed to the adjacent sides of the set of bases 101, forming a support structure. The telescopic rod 202, located between the low frame rod 102 and the high frame rod 103, provides lateral support and guidance when operated by the drive motor 201, ensuring the stable operation of the telescopic rod 202 and its connected components.

[0027] Sliding sleeves 104 are slidably connected to the inner walls of both sides of the low frame rod 102 and the high frame rod 103. Mounting grooves 106 are formed on the outer wall of the top side of the two adjacent sliding sleeves 104. Two sets of bearing seats 203 are rotatably connected within the mounting grooves 106 of the two sets of sliding sleeves 104. This arrangement allows the sliding sleeves 104 to slide along the inner walls of both sides of the low frame rod 102 and the high frame rod 103 during the use of the single yarn strength machine. When the position of the shrinkage assembly 2 needs to be adjusted, the sliding sleeves 104 move, and the bearing seats 203 rotatably connected within their mounting grooves 106 change position accordingly, thereby adjusting the lateral position of components such as the rotating shaft 204 and the roller limiting sleeve 205 to adapt to different yarn fixing requirements.

[0028] Manual rollers 109 are rotatably connected to the inner walls of the top two sides of the low frame rod 102. A first set of lead screw stepping components 107 is mounted at the bottom of the manual rollers 109, extending downwards to the bottom of a sliding sleeve 104. The sliding sleeve 104 is mounted on the outer wall of the first set of lead screw stepping components 107. This arrangement allows the manual rollers 109 on both sides of the top of the low frame rod 102 to rotate during operation, driving the first set of lead screw stepping components 107 to rotate downwards. The sliding sleeve 104 is mounted on the outer wall of the lead screw. As the lead screw rotates, the sliding sleeve 104 slides up and down along the lead screw, allowing for precise manual adjustment of the vertical position of the sliding sleeve 104 on the low frame rod 102, thereby adjusting the height of the bearing seat 203 and the shrinkage assembly 2.

[0029] Motors 108 are mounted on the outer walls of the top two sides of the high frame rod 103. A second set of lead screw stepping components 107 is mounted at the bottom of the motors 108, extending through the high frame rod 103 to the bottom of the sliding sleeve block 104. This arrangement is intended to allow the motors 108 on both sides of the top of the high frame rod 103 to be activated during the operation of the single yarn strength tester. The motors 108 drive the second set of lead screw stepping components 107 to operate, extending through the high frame rod 103 to the bottom of the sliding sleeve block 104. The sliding sleeve block 104 slides up and down as the lead screw rotates, achieving automated and precise adjustment of the vertical position of the sliding sleeve block 104 on the high frame rod 103, accurately adjusting the height of the shrinkage component 2 to meet the needs of different testing scenarios.

[0030] A locking screw 105 is threaded onto one inner wall of the sliding sleeve 104. The tail end of the locking screw 105 extends through into the mounting groove 106 and abuts against one outer wall of the bearing housing 203. This arrangement is intended to ensure that during the operation of the single yarn strength machine, after the sliding sleeve 104 adjusts the bearing housing 203 to a suitable position, the locking screw 105 is rotated so that its tail end extends through the inner wall of the sliding sleeve 104 into the mounting groove 106. The locking screw 105 is then gradually tightened until its tail end abuts against one outer wall of the bearing housing 203, firmly locking the bearing housing 203 within the mounting groove 106 of the sliding sleeve 104. This prevents the bearing housing 203 from shifting during operation and ensures stable operation of the shrinkage assembly 2.

[0031] During use, when operating this single yarn strength tester, according to the yarn testing requirements, rotate the manual rotary wheel 109 at the top of the low frame rod 102 to drive the first set of lead screw stepping components 107 to rotate, causing the sliding sleeve 104 to slide up and down on the low frame rod 102 to adjust the height of the bearing seat 203 on that side; simultaneously, start the motor 108 at the top of the high frame rod 103 to drive the second set of lead screw stepping components 107, causing the sliding sleeve 104 to slide up and down on the high frame rod 103 to adjust the height of the bearing seat 203 on that side; after adjustment, rotate the locking screw 105 so that its tail end abuts against the outer wall of the bearing seat 203, thus adjusting the bearing seat 203. The bearing housing 203 is firmly locked in the mounting groove 106 of the sliding sleeve block 104 to ensure the stable position of the shrinking component 2. The drive motor 201 on the outer wall of the right base 101 is started. The drive motor 201 drives the telescopic rod 202 to operate. The telescopic rod 202 passes through the base 101 to transmit power, causing the rotating shaft 204 to slide on the inner wall of the roller limiting sleeve 205. The shrinking component 2 starts to work, shrinking or adjusting the position of the yarn. Based on the yarn adjustment by the shrinking component 2, the high-strength stretching component 1 works in conjunction, continuously providing power through the drive motor 201 to achieve operations such as stretching the yarn and completing the single yarn strength test.

[0032] By connecting the drive motor 201 with the telescopic rod 202, the operation of the drive motor can directly drive the telescopic rod to move, providing stable power to the shrinking assembly 2, ensuring smooth operation of yarn shrinking and other operations, and improving the working efficiency of the equipment. The rotating shaft 204 is slidably connected to the roller limit sleeve 205, making the internal structure of the shrinking assembly more flexible during operation, adapting to the shrinking needs of different specifications of yarn, and enhancing the equipment's adaptability to various yarns.
