Description

Technical Field

[0001] This utility model relates to the field of low elasticity yarn production technology, specifically a twisting device for low elasticity yarn production. Background Technology

[0002] Low-elasticity yarn is a type of pre-oriented yarn. It is a finished yarn produced by continuously or simultaneously stretching and deforming the yarn using a texturing machine and a false twister. After the low-elasticity yarn is produced, workers sometimes need to use it to make double-strand yarn. Double-strand yarn is made by winding two low-elasticity yarns together to form a twist. Then, workers wind the double-strand yarns onto a spool. This process is called the twisting of low-elasticity yarn.

[0003] The existing plying equipment for producing low-elasticity yarn requires the take-up roller to be replaced after plying. The replacement time for the take-up roller is relatively long, and it is not possible to replace the take-up roller quickly. Moreover, the plying equipment is stopped during the replacement process. The plying equipment needs to be restarted after the take-up roller is replaced, which affects the plying efficiency of low-elasticity yarn. Utility Model Content

[0004] The purpose of this invention is to provide a stranding device for producing low-elasticity yarn, which features the ability to quickly replace the take-up roller to improve the stranding efficiency of low-elasticity yarn.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stranding device for producing low-elasticity yarn, comprising a base, a first vertical plate fixedly connected to the upper end face of the base, a triangular turntable rotatably connected to the front end face of the first vertical plate, three evenly distributed rotating cylinders rotatably connected to the front end face of the triangular turntable, a take-up roller sleeved on the outer wall of each of the three rotating cylinders, a plurality of evenly distributed sliding holes penetrating through the outer wall of each rotating cylinder, abutting blocks slidably connected to the inner walls of the plurality of sliding holes and abutting against the inner wall of the take-up rollers, a moving rod provided inside the rotating cylinder, a plurality of connecting rods distributed front and rear movably connected between the plurality of abutting blocks and the moving rod through hinge seats, and an electric telescopic rod installed on the front end face of the rotating cylinder, the output end of the electric telescopic rod extending into the interior of the rotating cylinder and fixedly connected to the moving rod;

[0006] The upper end face of the base is fixedly connected to a second vertical plate located to the right of the first vertical plate. The left side wall of the second vertical plate is rotatably connected to a rotating bracket. The left side wall of the rotating bracket is fixedly connected to two vertically distributed fixed plates. The left side wall of the rotating bracket is slidably connected to a movable plate located between the two fixed plates. The upper end faces of the upper movable plate and the lower fixed plate are rotatably connected to a rotating shaft. The outer walls of the two rotating shafts are fitted with wire feeding rollers.

[0007] A third vertical plate located between the first and second vertical plates is fixedly connected to the upper end face of the base, and a through hole is provided through the right side wall of the third vertical plate.

[0008] In order to drive the two moving plates to move in opposite directions, as a preferred embodiment of the low-elasticity yarn production stranding device of this utility model, a sliding groove is provided on the left side wall of the second vertical plate, and a bidirectional lead screw is rotatably connected inside the sliding groove. The right side walls of the two moving plates are fixedly connected with sliders threaded to the bidirectional lead screw. The upper end of the bidirectional lead screw extends to the top of the second vertical plate and is fixedly connected with a torsion block.

[0009] In order to drive the triangular turntable to rotate, as a preferred embodiment of the low-elasticity yarn production stranding device of this utility model, a first motor is installed on the rear end face of the first vertical plate, and the output end of the first motor is fixedly connected to the triangular turntable.

[0010] In order to drive multiple rotating drums to rotate, as a preferred embodiment of the low-elasticity yarn production stranding device of this utility model, multiple evenly distributed second motors are installed on the rear end face of the triangular turntable, and the output ends of the multiple second motors are respectively fixedly connected to the multiple rotating drums.

[0011] In order to drive the rotating support to rotate, as a preferred embodiment of the low-elasticity yarn production stranding device of this utility model, a third motor is installed on the right side wall of the second vertical plate, and the output end of the third motor is fixedly connected to the rotating support.

[0012] In order to limit the rotation shaft, as a preferred embodiment of the low elasticity yarn production stranding device of this utility model, the lower end faces of the upper fixed plate and the upper moving plate are respectively provided with limiting grooves that match the two rotation shafts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] After the first take-up roller at the top completes its winding, it stops rotating. Then, the first motor, in conjunction with a triangular turntable and three rotating drums, drives the three take-up rollers to rotate 120 degrees. This causes the take-up rollers to switch positions. At this point, the low-elasticity yarn, after being wound and twisted, is supported by the second take-up roller at the top. Then, the worker cuts off a section of the wound and twisted low-elasticity yarn located between the first and second take-up rollers. One end of the wound and twisted low-elasticity yarn is then fixed to the outer wall of the second take-up roller. The second motor, in conjunction with the second rotating drum, drives the second take-up roller to rotate, winding the wound and twisted low-elasticity yarn around the outer wall of the second take-up roller. The first take-up roller, after winding, is then replaced, facilitating quick replacement of the take-up rollers and improving the twisting efficiency of the low-elasticity yarn.

[0023] Please see Figures 1 to 6A stranding device for producing low-elasticity yarn includes a base 1, a first vertical plate 2 fixedly connected to the upper end face of the base 1, a triangular turntable 3 rotatably connected to the front end face of the first vertical plate 2, three evenly distributed rotating drums 4 rotatably connected to the front end face of the triangular turntable 3, a take-up roller 5 sleeved on the outer wall of each of the three rotating drums 4, a plurality of evenly distributed sliding holes 6 penetrating through the outer wall of the rotating drums 4, abutting blocks 7 slidably connected to the inner walls of the plurality of sliding holes 6 and abutting against the inner wall of the take-up roller 5, a moving rod 8 provided inside the rotating drums 4, a plurality of connecting rods 9 distributed front and rear movably connected between the plurality of abutting blocks 7 and the moving rod 8 through hinge seats, and an electric telescopic rod 10 installed on the front end face of the rotating drums 4, the output end of the electric telescopic rod 10 extending into the interior of the rotating drums 4 and fixedly connected to the moving rod 8.

[0024] The upper end face of the base 1 is fixedly connected to a second vertical plate 11 located to the right of the first vertical plate 2. The left side wall of the second vertical plate 11 is rotatably connected to a rotating bracket 12. The left side wall of the rotating bracket 12 is fixedly connected to two vertically distributed fixed plates 13. The left side wall of the rotating bracket 12 is slidably connected to a movable plate 14 located between the two fixed plates 13. The upper end faces of the upper movable plate 14 and the lower fixed plate 13 are rotatably connected to a rotating shaft 15. The outer walls of the two rotating shafts 15 are sleeved with a wire feeding roller 16.

[0025] A third vertical plate 17 located between the first vertical plate 2 and the second vertical plate 11 is fixedly connected to the upper end face of the base 1. A through hole 18 is provided through the right side wall of the third vertical plate 17.

[0026] In this embodiment: during use, the two moving plates 14 move in opposite directions, and the upper moving plate 14 drives the upper rotating shaft 15 to move downward, so that the two rotating shafts 15 move out of the two limiting grooves 25 respectively. Then, the two feeding rollers 16 are respectively sleeved on the outer wall of the two rotating shafts 15. Then, the two moving plates 14 move in opposite directions, so that the two rotating shafts 15 re-enter the two limiting grooves 25. Then, the operator pulls the two low-elasticity wires through the through hole 18 and fixes them to the outer wall of the first upper winding roller 5.

[0027] After preparation is complete, the rotating bracket 12 rotates, and the rotating bracket 12, in conjunction with the through hole 18, causes the two low-elasticity wires to rotate, wind, and twist together. At the same time, the first rotating drum 4 located above rotates, and the first rotating drum 4 located above drives the first winding roller 5 located above to rotate. The first winding roller 5 located above drives the low-elasticity wires after winding and twisting to wind around its outer wall, thereby performing the twisting process on the low-elasticity wires. When winding the low-elasticity wires after winding and twisting, the winding mechanism lays out the low-elasticity wires after winding and twisting, so that the low-elasticity wires after winding and twisting are flatly wound onto the outer wall of the winding roller 5.

[0028] After the first take-up roller 5 at the top finishes winding, it stops rotating. Then, the triangular turntable 3 rotates, and the triangular turntable 3, together with the three rotating drums 4, drives the three take-up rollers 5 to rotate 120 degrees, causing the second take-up roller 5 located on the lower right to rotate to the top. At the same time, the first take-up roller 5 at the top rotates to the lower left. At this time, the low-elasticity yarn after winding and twisting is supported by the second take-up roller 5 that has rotated to the top. Then, the worker cuts off a section of the low-elasticity yarn after winding and twisting located between the first take-up roller 5 and the second take-up roller 5. Then, one end of the low-elasticity yarn after winding and twisting is fixed to the outer wall of the second take-up roller 5. Then, the second rotating drum 4 drives the second take-up roller 5 to rotate, winding the low-elasticity yarn after winding and twisting onto the outer wall of the second take-up roller 5. Then, the first take-up roller 5 that has finished winding is replaced, which facilitates the quick replacement of the take-up roller 5 and improves the twisting efficiency of the low-elasticity yarn.

[0029] When replacing the take-up roller 5, the electric telescopic rod 10 extends and pushes the moving rod 8 backward. The moving rod 8, together with multiple connecting rods 9, drives multiple abutment blocks 7 to move in opposite directions, thereby releasing the fixing state of the multiple abutment blocks 7 on the take-up roller 5. Then, the finished take-up roller 5 is removed from the outer wall of the drum 4. Then, the other take-up rollers 5 are put back onto the outer wall of the drum 4. Then, the electric telescopic rod 10 retracts and drives the moving rod 8 forward. The moving rod 8, together with multiple connecting rods 9, drives multiple abutment blocks 7 to move in opposite directions, so that the multiple abutment blocks 7 abut against the inner wall of the replaced take-up roller 5, thereby fixing the replaced take-up roller 5, thus completing the replacement of the take-up roller 5.

[0030] The jointing device is controlled by an external control computer.

[0031] As a technical optimization of this utility model, a sliding groove 19 is provided on the left side wall of the second vertical plate 11. A bidirectional lead screw 20 is rotatably connected inside the sliding groove 19. A slider 21 that is threadedly connected to the bidirectional lead screw 20 is fixedly connected to the right side wall of both moving plates 14. The upper end of the bidirectional lead screw 20 extends to the top of the second vertical plate 11 and is fixedly connected to a torsion block.

[0032] In this embodiment: the torsion block drives the bidirectional lead screw 20 to rotate, and the bidirectional lead screw 20, together with the two sliders 21, drives the two moving plates 14 to move in opposite directions.

[0033] As a technical optimization of this utility model, a first motor 22 is installed on the rear end face of the first vertical plate 2, and the output end of the first motor 22 is fixedly connected to the triangular turntable 3.

[0034] In this embodiment: the first motor 22 is started, and the first motor 22 drives the triangular turntable 3 to rotate.

[0035] As a technical optimization of this utility model, a plurality of evenly distributed second motors 23 are installed on the rear end face of the triangular turntable 3, and the output ends of the plurality of second motors 23 are respectively fixedly connected to a plurality of rotating drums 4.

[0036] In this embodiment: multiple second motors 23 are started, and the multiple second motors 23 drive multiple rotating drums 4 to rotate respectively.

[0037] As a technical optimization of this utility model, a third motor 24 is installed on the right side wall of the second vertical plate 11, and the output end of the third motor 24 is fixedly connected to the rotating bracket 12.

[0038] In this embodiment: the third motor 24 is started, and the third motor 24 drives the rotating bracket 12 to rotate.

[0039] As a technical optimization of this utility model, the lower end surfaces of the upper fixed plate 13 and the upper movable plate 14 are provided with limiting grooves 25 that respectively match the two rotating shafts 15.

[0040] In this embodiment, the limiting groove 25 can limit the rotation of the shaft 15, so that the shaft 15 can rotate smoothly.

[0041] Working principle: In use, the torsion block drives the bidirectional lead screw 20 to rotate. The bidirectional lead screw 20, together with the two sliders 21, drives the two moving plates 14 to move in opposite directions. The upper moving plate 14 drives the upper rotating shaft 15 to move downward, so that the two rotating shafts 15 move out of the two limiting grooves 25 respectively. Then, the two pay-off rollers 16 are respectively fitted onto the outer wall of the two rotating shafts 15. Then, the two moving plates 14 move in opposite directions, so that the two rotating shafts 15 re-enter the two limiting grooves 25. Then, the operator pulls the two low-elasticity wires through the through hole 18 and fixes them to the outer wall of the first take-up roller 5 located above.

[0042] After preparation is complete, the third motor 24 is started. The third motor 24 drives the rotating bracket 12 to rotate. The rotating bracket 12, in conjunction with the through hole 18, causes the two low-elasticity wires to rotate, wind, and twist together. At the same time, the first second motor 23 located above is started. The first second motor 23 drives the first rotating drum 4 located above to rotate. The first rotating drum 4 located above drives the first take-up roller 5 located above to rotate. The first take-up roller 5 located above winds the twisted low-elasticity wires to wind around its outer wall, thereby performing the twisting process on the low-elasticity wires. When winding the twisted low-elasticity wires, the winding mechanism lays out the twisted low-elasticity wires so that the twisted low-elasticity wires are flatly wound onto the outer wall of the take-up roller 5.

[0043] After the first take-up roller 5 at the top finishes winding, the first second motor 23 at the top stops rotating, and then the first motor 22 is started. The first motor 22 drives the triangular turntable 3 to rotate, and the triangular turntable 3, together with the three rotating drums 4, drives the three take-up rollers 5 to rotate 120 degrees, so that the second take-up roller 5 located on the lower right side rotates to the top. At the same time, the first take-up roller 5 located at the top rotates to the lower left side. At this time, the low-elasticity yarn after winding and twisting is supported by the second take-up roller 5 that has rotated to the top. Then, the worker cuts off a section of the low-elasticity yarn after winding and twisting located between the first take-up roller 5 and the second take-up roller 5. Then, one end of the low-elasticity yarn after winding and twisting is fixed to the outer wall of the second take-up roller 5. Then, the second second motor 23 is started, and the second second motor 23, together with the second rotating drum 4, drives the second take-up roller 5 to rotate, winding the low-elasticity yarn after winding and twisting onto the outer wall of the second take-up roller 5. Then, the first take-up roller 5 that has finished winding is replaced, which facilitates the quick replacement of the take-up roller 5 and improves the twisting efficiency of the low-elasticity yarn.

[0044] When replacing the take-up roller 5, the electric telescopic rod 10 extends, pushing the moving rod 8 backward. The moving rod 8, in conjunction with multiple connecting rods 9, drives multiple abutment blocks 7 to move in opposite directions, thereby releasing the fixing state of the multiple abutment blocks 7 on the take-up roller 5. Then, the finished take-up roller 5 is removed from the outer wall of the drum 4. Then, the other take-up rollers 5 are reattached to the outer wall of the drum 4. Then, the electric telescopic rod 10 retracts, driving the moving rod 8 forward. The moving rod 8, in conjunction with multiple connecting rods 9, drives multiple abutment blocks 7 to move in opposite directions, so that the multiple abutment blocks 7 abut against the inner wall of the replaced take-up roller 5, thereby fixing the replaced take-up roller 5, thus completing the replacement of the take-up roller 5.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
