Description

Technical Field

[0001] The invention relates to the technical field of chemical fiber equipment, in particular to a temporary clamping component for breaking a silk thread of a chemical fiber two-for-one twisting machine. Background Art

[0002] Chemical fiber double twister is a twisting device, which is a textile mechanical equipment that twists multiple strands of yarn into one strand. Its function is to process yarn or combined strands of yarn into linear products. The double yarn bobbin is placed on a stationary hollow tube. The double yarn is led out from the top of the bobbin, passes through the hollow tube, and then enters the radial hole of the spindle tube and the yarn storage disk. The yarn storage disk rotates with the spindle, and the yarn is twisted with each rotation of the spindle, which is basically the same as the twisting nature of the ring twister.

[0003] However, during the processing, since the chemical fiber threads are in a taut state, they are easily broken when the pulling force is too large. The broken threads fall down and are easily entangled with other threads. Workers cannot find them immediately.

DETAILED DESCRIPTION

[0027] The embodiment of the present invention provides a temporary clamping assembly for breaking a thread of a chemical fiber two-for-one twisting machine, such as Figure 1-5As shown, the base 1 includes a plurality of twisting modules arranged at equal distances from bottom to top, and the twisting module consists of a base 2, two rings 3, two clamping assemblies 4, two tensioning assemblies 5, two sleeves 6 and a rotating block 7. The tensioning assembly 5 is arranged on the left side of the base 2, the ring 3 is arranged on the right side of the base 2, the clamping assembly 4 is slidably fitted between the base 2 and the ring 3, the sleeve 6 is arranged on the right side of the ring 3, and the rotating block 7 is arranged on the right side of the sleeve 6. The wire passes through the tensioning assembly 5, the base 2, the clamping assembly 4, the clamping assembly 4, the sleeve 6 and the rotating block 7 in sequence along the routing direction.

[0028] Two connecting rods 31 are welded between the ring 3 and the base 2, and the wire is located between the two connecting rods 31. The clamping assembly 4 includes two driving seats 41, two clips 42 and two electromagnet units 45. The driving seats 41, the clips 42, the electromagnet units 45 correspond to the connecting rods 31 one by one, and the driving seats 41 and the connecting rods 31 are slidably matched. There is a driving wheel in the driving seat 41, and the driving seat 41 is driven to move back and forth by the rotation of the driving wheel.

[0029] The clip 42 is slidably matched with the driving seat 41, and the two clips 42 are respectively located on both sides of the wire, and the side of the clip 42 away from the wire is fixedly installed with the electromagnet unit 45. When the two supporting rods 43 are energized, a magnetic field of mutual attraction is generated, so that the two clips 42 fit together to clamp the wire.

[0030] It also includes a support rod 43, a small spring 44, a connecting piece 46, and a motor 47. The connecting piece 46 is located between the clip 42 and the drive seat 41, and the connecting piece 46 is welded to the support rod 43 on the side facing the clip 42. The support rod 43 passes through the clip 42, and the small spring 44 is sleeved outside the support rod 43. One end of the small spring 44 is welded to the end of the support rod 43 away from the clip 42, and the other end of the small spring 44 is welded to the clip 42. The motor 47 is fixedly installed on the side of the drive seat 41, and the transmission shaft of the motor 47 is welded to the connecting piece 46.

[0031] The transmission shafts of the two motors 47 of the same clamping assembly 4 are aligned with each other and are on the same horizontal line. The small spring 44 is used to force the two clips 42 to move away from each other.

[0032] When the thread is broken, the thread is loose and falls down as a whole, and the electromagnet unit 45 is energized to generate a magnetic field, which attracts each other and makes the two clamps 42 fit together, and the small spring 44 is squeezed. After the clamp 42 fits together, it clamps one end of the broken thread, and at the same time, the drive seat 41 slowly moves toward the ring 3 to tighten the thread again, and at the same time, the motor 47 drives the clamp 42 to rotate, and the clamped hanging thread is wound and collected to prevent the broken and hanging thread from being entangled with other threads.

[0033] When the wire breakage is located inside the sleeve 6, the wire can also be wound in this way to pull the broken wire out of the sleeve 6 in advance, thereby speeding up the subsequent repair work efficiency.

[0034] There is a protrusion 21 on the left side of the base 2, and two slide bars 22 are welded at the bottom of the protrusion 21. The tensioning assembly 5 is located between the two slide bars 22. The tensioning assembly 5 includes a slider 51, a roller 1 52, and a roller 2 53. The upper end of the slider 51 is pivotally connected to the roller 1 52, and the lower end of the slider 51 is pivotally connected to the roller 2 53. A hoop 54 is connected to the outer surface of the slider 51, and the slide bar 22 passes through the hoop 54. As can be seen from the accompanying drawings, the silk thread passes between the roller 1 52 and the roller 2 53.

[0035] A tension sensing unit 23 is fixedly mounted on one end of the slide bar 22 away from the base 2 , a warning light 24 is fixedly mounted on the tension sensing unit 23 , and a large spring 55 is welded between the tension sensing unit 23 and the hoop 54 .

[0036] The entire two-for-one twister is also fixedly installed with a control module, which controls the operation of the electronic parts. When the silk thread is in a normal state, the silk thread drags the slider 22, so that the large spring 55 is stretched. The tension sensing unit 23 adds a measured value and transmits it to the control module of the entire device. At this time, the warning light 24 is green. When the silk thread breaks and falls, the large spring 55 shrinks, and the value measured by the tension sensing unit 23 becomes smaller. At this time, the warning light 24 is red. The control module controls the clamping assembly 4 to work.

[0037] The sleeve 6 is hollow inside, and a plurality of connecting pieces 61 are welded to the inner wall of the sleeve 6. An elastic film 62 is fixedly installed inside the sleeve 6. The sleeve 6, the connecting piece 61, and the elastic film 62 surround an expansion cavity 63, and the connecting piece 61 is provided with a through hole, so that adjacent expansion cavities 63 are interconnected. An air pump 16 is fixedly installed on the top of the base 1, and a hose is fixedly installed on the working end of the air pump 16, and the hose is connected to the sleeve 6.

[0038] Air is continuously injected into the expansion chamber 63 of the sleeve 6 through the air pump 16, and the expansion chamber 63 is inflated to clamp the other end of the broken thread. If the broken part of the thread is located between the ring 3 and the sleeve 6, since the sleeve 6 is long, it can be effectively assembled to reduce the length of the thread hanging down, thereby having a certain effect of preventing the thread from hanging down and entangled with other normal threads.

[0039] A vertical connecting column 11, a bracket 12, and a bracket 2 13 are fixedly installed on the top of the base 1. The connecting column 11 is fixedly installed with the base 2. The sleeve 6 is fixedly installed in the bracket 12. The rotating block 7 is pivoted in the bracket 2 13. A gear 131 driven by a motor is fixedly installed in the bracket 2 13. A tooth groove 71 is provided on the outer surface of the rotating block 7. The gear 131 meshes with the tooth groove 71. Multiple silk threads pass through a rotating block 7 together, and the gear 131 drives the rotating block 7 to select, thereby achieving the purpose of doubling the twist.

[0040] A traction roller 14 is pivotally connected to the top of the base 1 , and the traction roller 14 is located between the ring 3 and the sleeve 6 .

[0041] A plurality of screw holes 15 are provided at equal distances on the top, and the connecting column 11, the bracket 1 12, and the bracket 2 13 are fixedly mounted on the base 1 through the screw holes 15 and the screws. Since there are many screw holes, the distances between the connecting column 11, the bracket 1 12, and the bracket 2 13 can be changed according to actual needs, thereby changing the length of the entire two-for-one twisting module.

[0042] In summary, the temporary clamping assembly for broken silk threads of the chemical fiber double twisting machine is provided with a base 2, a ring 3 and a sleeve 6, and a plurality of clamping assemblies 4 are slidably matched between the ring 3 and the base 2, and the clamping assembly includes a driving seat 41, a clamping piece 42, and an electromagnet unit 45. The electromagnet unit 45 is energized to generate a magnetic field, so that the two clamping pieces 42 are close to each other and fit together, so as to achieve the purpose of clamping the silk thread. The entire clamping assembly is driven to rotate by a motor 47, so as to achieve the purpose of winding up the broken thread ends, thereby achieving the purpose of collecting the broken thread ends and preventing the broken silk threads from falling and getting entangled with other silk threads.

[0043] In addition, an expandable expansion chamber 63 is provided in the sleeve 6. When air is inflated into the expansion chamber 63 and the expansion chamber 63 swells, the elastic film 62 clamps the silk thread, thereby preventing the broken thread from falling.

[0044] In addition, a sliding rod 22 is set on the side of the base 2, and a tension sensing unit 23 is connected to the end of the sliding rod 22, and a warning light 24 is connected to the tension sensing unit 23. The sliding rod 22 is equipped with a tensioning component 5, and a large spring 55 is connected between the tensioning component 6 and the tension sensing unit 23. The tension sensing unit 23 senses whether the silk thread is broken, and the warning light 24 lights up when the silk thread is broken, so as to achieve the purpose of reminding the workers.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
