Description

Technical Field

[0001] This utility model relates to the technical field of chemical fiber production, and in particular to a false twisting device for chemical fiber texturing equipment. Background Technology

[0002] False twisting involves fixing both ends of the rope and applying twist in the middle. Although one side becomes tighter as it twists, the total number of twists on the rope remains zero because the other side twists in the opposite direction. This method makes the yarn appear twisted, but in reality, no true twist is formed inside the fiber.

[0003] According to Chinese Patent Publication No. CN217149455U, this utility model relates to the technical field of false twisting devices, and more particularly to a false twisting device for chemical fiber texturing equipment. It includes an operating table with supporting legs at the corners of its bottom surface. A twisting assembly is located in the center of the top surface of the operating table. The twisting assembly includes a rotating ring, a connecting plate, a fixed bobbin, a fixing bolt, an outer sleeve, a support rod, and a vertical plate. The rotating ring is located in the center of the top of the operating table. A drive wheel, a connecting shaft, and a motor drive the rotating ring to rotate. The fixing bolt secures the yarn passing through the fixed bobbin. The outer sleeve, support rod, and vertical plate support the rotating ring and the fixed bobbin, thereby achieving the purpose of twisting the yarn in the middle. Furthermore, a fixed clamp, a movable clamp, a screw, and a nut secure both ends of the yarn. When the twisting assembly twists the yarn, it achieves automatic false twisting of the yarn. The structure is simple.

[0004] According to the aforementioned patent, a motor drives a drive wheel to rotate, causing a rotating ring to rotate. This causes the fixed bobbin inside the rotating ring to falsely twist the synthetic fiber. Although this method can easily achieve the false twisting action, the strength of the synthetic fiber is limited. When the false twisting amplitude of the synthetic fiber is too large, causing the tensile force on the synthetic fiber to exceed the maximum tensile force that the synthetic fiber can withstand, the synthetic fiber will break, resulting in the loss of the synthetic fiber. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a false twist device for chemical fiber texturing equipment, so as to solve the technical problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A false twisting device for texturing chemical fiber yarn includes a base, with brackets fixedly connected to the top left and right sides of the base.

[0008] There are two wire clamping assemblies, which are respectively installed in two brackets to fix the two ends of the chemical fiber filaments.

[0009] The false twist assembly, located in the middle of the base, comprises a motor, pulleys, a bobbin, a pressing element, a clamp, a torque unit, and a pressure switch. The motor is mounted at the bottom of the base, and pulleys are rotatably connected to both the top and bottom of the base, connected by a belt. The pulley at the bottom of the base is fixedly connected to the output shaft of the motor. A circular hole is opened in the middle of the pulley at the top of the base, and a clamp is fixedly connected to the hole via a connecting rod. A notch is provided on one side of the clamp, making it C-shaped. A pressure switch is fixedly connected to one side of the notch. A bobbin is coaxially arranged in the circular hole, and a pressing element for pressing the chemical fiber is connected to the outer wall of the bobbin at the position inside the notch. The outer wall of the bobbin is connected to the clamp via a torque unit.

[0010] Furthermore, the torque unit includes a limiting block and a top block. The inner wall of the clamp is provided with a track groove, and the side wall of the track groove is provided with a circular groove. The top block is connected to the circular groove by a support spring. The limiting block is slidably arranged in the track groove. The outer wall of the limiting block is provided with a slot that engages with the top block. The side of the limiting block away from the clamp is fixedly connected to the spool.

[0011] Furthermore, the outer wall of the clamp is provided with a threaded hole communicating with the circular groove, and an adjusting screw is threaded into the threaded hole.

[0012] Furthermore, a compression spring is fixedly connected to the side of the limiting block away from the pressure switch, and the end of the compression spring away from the limiting block is fixedly connected to the end of the track groove.

[0013] Furthermore, the wire pressing component includes a sleeve, a lead screw, and a pressure block. The sleeve is rotatably connected to the spool, and the lead screw is threadedly connected to the sleeve. The bottom end of the lead screw extends into the spool and is fixedly connected to the pressure block.

[0014] Furthermore, the bottom of the pressure block is concave to form an arc surface, and a rubber pad is attached to the arc surface.

[0015] Furthermore, the wire clamping assembly includes an upper pressure plate, a lower pressure plate, a slider, a screw, and an adjusting plate. The side wall of the bracket is provided with a sliding groove, and a screw is rotatably connected in the sliding groove. The top of the screw extends above the bracket and is fixedly connected to the adjusting plate. The outer wall of the screw is threadedly connected to a slider. The upper pressure plate is fixedly connected to the side of the slider that extends out of the sliding groove. The lower pressure plate is fixedly connected to the side wall of the bracket at the bottom of the sliding groove.

[0016] In summary, this utility model has at least one of the following beneficial technical effects:

[0017] 1. A false twist device for a chemical fiber texturing equipment, which, through the set false twist component, can protect the chemical fiber while false twisting it. The clamp and the spool are connected through a torque unit. When the tension exceeds the critical value of the torque unit, the clamp and the spool will unlock, thereby allowing the pulley to spin freely and preventing the chemical fiber from being twisted and broken. This can effectively improve the practicality of the false twist device.

[0018] 2. This false twisting device for chemical fiber texturing equipment has a notch on one side of the clamp, and a pressure switch is fixedly connected to one side of the notch. At the same time, a pressing element for pressing the chemical fiber is connected to the outer wall of the spool inside the notch. Therefore, when the clamp is unlocked from the spool, as the clamp rotates, the pressing element connected to the spool will abut against the pressure switch, thereby actively shutting down the motor, protecting the chemical fiber and reducing the energy consumption of the motor, which can further improve the practicality of the false twisting device.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example:

[0028] Reference Figure 1 - Figure 5 The present invention discloses a false twist device for a chemical fiber texturing equipment, which includes a base 1, and brackets 4 are fixedly connected to the top left and right sides of the base 1.

[0029] Two wire clamping assemblies 2 are provided, and the two wire clamping assemblies 2 are respectively installed in the two brackets 4 to fix the two ends of the chemical fiber filaments;

[0030] The false twist assembly 3 is located in the middle of the base 1. The false twist assembly 3 includes a motor 31, a pulley 32, a bobbin 33, a pressing element 34, a clamp 35, a torque unit 36, and a pressure switch 37. The motor 31 is installed at the bottom of the base 1. The top and bottom of the base 1 are rotatably connected to the pulley 32, which is connected by a belt. The pulley 32 at the bottom of the base 1 is fixedly connected to the output shaft of the motor 31. The pulley 32 at the top of the base 1 has a circular hole 5 in the middle. The clamp 35 is fixedly connected to the circular hole 5 by a connecting rod. A notch 6 is provided on one side of the clamp 35, making the clamp 35 C-shaped. The pressure switch 37 is fixedly connected to one side of the notch 6. The bobbin 33 is coaxially arranged in the circular hole 5. The outer wall of the bobbin 33 is connected to the pressing element 34 for pressing the chemical fiber filaments at the position inside the notch 6. The outer wall of the bobbin 33 is connected to the clamp 35 through the torque unit 36.

[0031] In this embodiment, observation Figure 1 It can be seen that the top left and right sides of the base 1 are fixedly connected to the brackets 4. The side walls of the two brackets 4 are provided with sliding grooves 14. The sliding grooves 14 are provided with wire clamping components 2, which can be used to fix the two ends of the chemical fiber filaments.

[0032] Subsequently Figure 2It can be seen that a false twist assembly 3 is provided in the middle of the base 1. The false twist assembly 3 includes a motor 31, a pulley 32, a bobbin 33, a pressing component 34, a clamp 35, a torque unit 36, and a pressure switch 37. The motor 31 is installed at the bottom of the base 1. The top and bottom of the base 1 are rotatably connected to the pulley 32. The two pulleys 32 are connected by a belt. The pulley 32 at the bottom of the base 1 is fixedly connected to the output shaft of the motor 31. The pulley 32 at the top of the base 1 has a circular hole 5 in the middle. The clamp 35 is fixedly connected to the circular hole 5 by a connecting rod. A notch 6 is provided on one side of the clamp 35 to make the clamp 35 C-shaped. The pressure switch 37 is fixedly connected to one side of the notch 6. The bobbin 33 is coaxially arranged in the circular hole 5. The outer wall of the bobbin 33 is connected to the pressing component 34 for pressing the chemical fiber filaments at the position inside the notch 6. The outer wall of the bobbin 33 is connected to the clamp 35 through the torque unit 36.

[0033] When it is necessary to false twist the chemical fiber, one end of the chemical fiber can be connected to the wire clamping assembly 2 on the left, and the other end of the chemical fiber can be connected to the wire clamping assembly 2 on the right after passing through the bobbin 33, so as to achieve the initial fixation of the chemical fiber.

[0034] After initial fixing, the wire pressing component 34 can be rotated to fix the chemical fiber filaments inside the bobbin 33. Once the chemical fiber filaments are fixed, the start switch of the motor 31 can be pressed. Figure 1 (As shown in the middle left front position), at this time the motor 31 will run and drive the pulley 32 below the base 1 to rotate, and through the belt, drive the pulley 32 above the base 1 to rotate, thereby starting the false twisting operation.

[0035] Finally, once the false twisting is complete, the false twisting can be stopped by pressing the stop switch on motor 31. Then, the chemical fiber yarn can be removed to complete the texturing operation of the chemical fiber yarn.

[0036] In the false twisting process of synthetic fibers, as the false twisting amplitude of the fibers increases, the tensile force on the fibers also increases. If the operator fails to shut off the motor 31 in time, the excessive torsional force on the fibers can cause them to break, resulting in damage. Therefore, in Figure 4 It can be seen that the clamp 35 and the spool 33 are connected through the torque unit 36. When the tension exceeds the critical value of the torque unit 36, the clamp 35 and the spool 33 will be unlocked, thereby allowing the pulley 32 to spin freely and preventing the chemical fiber filaments from being twisted and broken.

[0037] Then looked at Figure 3It can be seen that a notch 6 is provided on one side of the clamp 35, making the clamp 35 C-shaped. A pressure switch 37 is fixedly connected to one side of the notch 6. At the same time, a pressing element 34 for pressing the chemical fiber is connected to the outer wall of the spool 33 inside the notch 6. Therefore, when the clamp 35 is unlocked from the spool 33, as the clamp 35 rotates, the pressing element 34 connected to the spool 33 will abut against the pressure switch 37, thereby actively shutting down the motor 31, protecting the chemical fiber and reducing the energy consumption of the motor 31, which can further improve the practicality of the false twisting device.

[0038] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the torque unit 36 ​​includes a limiting block 361 and a top block 362. The inner wall of the clamp 35 is provided with a track groove 7, and the side wall of the track groove 7 is provided with a circular groove 8. The top block 362 is connected to the circular groove 8 by a support spring. The limiting block 361 is slidably arranged in the track groove 7. The outer wall of the limiting block 361 is provided with a slot 9 that engages with the top block 362. The side of the limiting block 361 away from the clamp 35 is fixedly connected to the spool 33.

[0039] The outer wall of the clamp 35 is provided with a threaded hole 10 that communicates with the circular groove 8, and an adjusting screw 11 is threaded into the threaded hole 10.

[0040] In this embodiment, the torque unit 36 ​​includes a limiting block 361 and a top block 362. The inner wall of the clamp 35 is provided with a track groove 7, and the side wall of the track groove 7 is provided with a circular groove 8. The top block 362 is connected to the circular groove 8 by a support spring. The limiting block 361 is slidably arranged in the track groove 7. The outer wall of the limiting block 361 is provided with a locking groove 9 that engages with the top block 362. The side of the limiting block 361 away from the clamp 35 is fixedly connected to the bobbin 33. This allows the tension on the chemical fiber to exceed the supporting force applied to the top block 362 by the support spring, causing the top block 362 to be pressed into the circular groove 8, thereby separating the clamp 35 from the bobbin 33 and preventing the chemical fiber from being twisted and broken.

[0041] Because the thickness of synthetic fibers varies depending on the application, different false twists are required to accommodate the different synthetic fibers. Figure 4 It can also be found that the outer wall of the clamp 35 is provided with a threaded hole 10 that communicates with the circular groove 8. An adjusting screw 11 is connected to the threaded hole 10. At this time, the compression range of the support spring can be changed by tightening the adjusting screw 11, thereby increasing the support force applied by the support spring to the top block 362, and thus increasing the maximum twisting force of the chemical fiber, which can effectively improve the applicability of the false twist device.

[0042] In a further preferred embodiment of this utility model, such as Figure 4As shown, a compression spring 12 is fixedly connected to the side of the limiting block 361 away from the pressure switch 37, and the end of the compression spring 12 away from the limiting block 361 is fixedly connected to the end of the track groove 7.

[0043] In this embodiment, the compression spring 12 can be used to pull the limit block 361 back to its original position after the pressure switch 37 is activated and the motor 31 is turned off by the wire pressing component 34, thereby realizing the reset of the clamp 35 and the spool 33, making the use of the false twist device simpler and more convenient.

[0044] In a further preferred embodiment of this utility model, such as Figure 5 As shown, the wire pressing component 34 includes a sleeve 341, a lead screw 342 and a pressing block 343. The sleeve 341 is rotatably connected to the spool 33. The lead screw 342 is internally threaded onto the sleeve 341. The bottom end of the lead screw 342 extends into the spool 33 and is fixedly connected to the pressing block 343.

[0045] The bottom of the pressure block 343 is concave to form an arc surface, and a rubber pad 13 is attached to the arc surface.

[0046] In this embodiment, the pressing component 34 includes a sleeve 341, a lead screw 342, and a pressing block 343. The sleeve 341 is rotatably connected to the bobbin 33, and the lead screw 342 is threadedly connected to the sleeve 341. The bottom end of the lead screw 342 extends into the bobbin 33 and is fixedly connected to the pressing block 343. By rotating the sleeve 341, the pressing block 343 can press the chemical fiber filaments in the bobbin 33 tightly to ensure that the chemical fiber filaments can be stably twisted.

[0047] By providing an arc surface at the bottom of the pressure block 343, and attaching a rubber pad 13 to the arc surface, the chemical fiber filaments can be protected from being damaged while ensuring their fixation strength, thus further improving the protection effect on the chemical fiber filaments.

[0048] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the wire clamping assembly 2 includes an upper pressure plate 21, a lower pressure plate 22, a slider 23, a screw 24, and an adjusting plate 25. The side wall of the bracket 4 is provided with a sliding groove 14. The screw 24 is rotatably connected in the sliding groove 14. The top of the screw 24 extends above the bracket 4 and is fixedly connected to the adjusting plate 25. The outer wall of the screw 24 is threadedly connected to the slider 23. The upper pressure plate 21 is fixedly connected to the side of the slider 23 that extends out of the sliding groove 14. The lower pressure plate 22 is fixedly connected to the side wall of the bracket 4 at the bottom of the sliding groove 14.

[0049] In this embodiment, the wire clamping assembly 2 includes an upper pressure plate 21, a lower pressure plate 22, a slider 23, a screw 24, and an adjusting plate 25. The side wall of the bracket 4 is provided with a sliding groove 14. The screw 24 is rotatably connected in the sliding groove 14. The top of the screw 24 extends above the bracket 4 and is fixedly connected to the adjusting plate 25. The outer wall of the screw 24 is threadedly connected to the slider 23.

The lower pressure plate 22 is fixedly connected to the side wall of the bracket 4 at the bottom of the sliding groove 14. This allows the chemical fiber to be quickly fixed during the false twisting operation, thereby improving the false twisting efficiency of the chemical fiber.
