Description

Technical Field

[0001] This utility model relates to the field of auxiliary accessories for winding machines, and in particular to a twisting device for winding machines. Background Technology

[0002] Winding machines, as key equipment in the textile industry, are mainly used to rewind yarn into cones that meet process requirements. During the winding process, yarn breakage or yarn replacement may necessitate splicing. In existing multi-station winding machines, each slotted drum station is typically equipped with an independent splicer to meet the splicing needs when winding yarn on the corresponding drum. However, this design has the following problems: equipping each drum with a dedicated splicer increases the number of hardware components, especially in large-scale multi-station winding machines, leading to a significant increase in cost. Moreover, multiple splicers require separate debugging and maintenance, increasing labor and time costs, and consistency is difficult to guarantee. Therefore, a splicing device for winding machines needs to be developed. Utility Model Content

[0003] The purpose of this invention is to provide a twisting device for a winding machine, thereby solving the technical problems mentioned in the background section.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a twisting device for a winding machine, comprising a frame plate, which is fixedly supported on the ground by four support legs respectively vertically fixed at its corners. The frame plate has an elongated clearance groove. A movable platform is slidably mounted on the upper part of the frame plate, and a translation drive mechanism for driving the movable platform to slide horizontally is provided between the frame plate and the movable platform. A lifting rod and a lifting drive mechanism for driving the lifting rod to slide vertically are vertically mounted on the movable platform. The lifting rod passes through the clearance groove and has a horizontal lifting seat fixedly mounted at its lower end. A twister is mounted on the lifting seat.

[0006] Furthermore, the translation drive mechanism includes two symmetrically fixed transmission racks on the upper part of the frame plate, and two first motors are symmetrically fixed on the upper part of the moving platform. The drive shafts of the two first motors pass through the moving platform and are provided at their ends with transmission gears that mesh with the corresponding transmission racks.

[0007] Furthermore, two vertical limiting plates are symmetrically arranged at the bottom of the mobile platform, and the two vertical limiting plates are flat against the two sides of the frame plate.

[0008] Furthermore, each of the vertical limiting plates is fixedly provided with a horizontal limiting plate at the position located on the upper and lower surfaces of the frame plate.

[0009] Furthermore, the lifting drive mechanism includes a vertical transmission cylinder fixedly disposed in the middle of the upper part of the moving platform and a horizontal transmission cylinder fixedly disposed outside the vertical transmission cylinder, the horizontal transmission cylinder being connected to the vertical transmission cylinder; a transmission turbine is rotatably disposed inside the vertical transmission cylinder, and a transmission worm gear adapted to the transmission turbine is rotatably disposed inside the horizontal transmission cylinder; a second motor for driving the transmission worm gear to rotate is fixedly disposed on the moving platform; an internal thread is formed on the inner peripheral wall of the transmission turbine, and an external thread adapted to the internal thread of the transmission turbine is formed on the outer peripheral wall of the lifting rod; both the moving platform and the vertical transmission cylinder are provided with through holes for the lifting rod to pass through.

[0010] Furthermore, a vertical mounting plate is fixedly installed on the moving platform, and the second motor is fixedly installed on the mounting plate, with its drive shaft connected to the transmission worm gear via a transmission shaft.

[0011] Furthermore, a limiting head is fixedly provided at the upper end of the lifting rod, and the outer diameter of the limiting head is larger than the inner diameter of the through hole on the top plate of the vertical transmission cylinder.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] When applied, this invention allows the twister to be aligned with the slotted drum station of the winding machine where yarn splicing is required. When other slotted drum stations require yarn splicing, the moving table and the twister can be moved horizontally and linearly to the corresponding slotted drum station via a translation drive mechanism. Therefore, by configuring a single twister, the yarn splicing requirements of multiple slotted drum stations of the winding machine can be met, thereby reducing the equipment cost of the winding machine. Furthermore, a single twister is easy to debug and maintain, effectively reducing labor and time costs.

[0014] In addition, this utility model can use a lifting drive mechanism to make the lifting rod drive the knotter on the lifting seat to move linearly in the vertical direction, so as to realize convenient adjustment of the height of the knotter, thereby meeting the work comfort of workers of different heights.

[0020] like Figures 1-3 As shown, a twisting device for a winding machine includes a frame plate 1, which is fixedly supported on the ground by four support legs 2 that are respectively vertically fixed at its corners. The frame plate 1 is provided with a long strip-shaped clearance groove 3.

[0021] A movable platform 4 is slidably mounted on the upper part of the frame plate 1, and a translation drive mechanism for driving the movable platform 4 to slide horizontally is provided between the frame plate 1 and the movable platform 4.

[0022] In this embodiment, the translation drive mechanism includes two symmetrical transmission racks 5 fixedly mounted on the upper part of the frame plate 1 along the length direction of the frame plate. Two first motors 6 are symmetrically fixedly mounted on the upper part of the moving platform 4. The drive shafts of the two first motors 6 respectively pass through the moving platform 4 and have transmission gears 7 at their ends that mesh with the corresponding transmission racks 5. When the two first motors 6 synchronously drive the two transmission gears 7 to rotate, the two transmission gears 7 maintain their meshing relationship with the two transmission racks 5, causing the moving platform 4 to slide along the length direction of the frame plate under the action of the meshing force.

[0023] Two vertical limiting plates 8 are symmetrically fixedly installed at the bottom of the mobile platform 4, and the two vertical limiting plates 8 are flat against the two sides of the frame plate 1. Each vertical limiting plate 8 has a horizontal limiting plate 20 fixedly installed at the upper and lower surfaces of the frame plate 1. Through the limiting effect of the two vertical limiting plates 8 and the two sets of horizontal limiting plates 20, the movement stability of the mobile platform 4 on the frame plate 1 can be guaranteed.

[0024] The mobile platform 4 is vertically and slidably equipped with a lifting rod 9 and a lifting drive mechanism for driving the lifting rod 9 to slide vertically.

[0025] The lifting drive mechanism includes a vertical transmission cylinder 10 fixedly installed in the middle of the upper part of the moving platform 4 and a horizontal transmission cylinder 11 fixedly disposed outside the vertical transmission cylinder 10. The horizontal transmission cylinder 11 is internally connected to the vertical transmission cylinder 10. A transmission turbine 12 is vertically and rotatably installed inside the vertical transmission cylinder 10, and a transmission worm gear 13 adapted to the transmission turbine 12 is rotatably installed inside the horizontal transmission cylinder 11. A second motor 14 for driving the transmission worm gear 13 to rotate is fixedly installed on the moving platform 4. Specifically, a vertical mounting plate 15 is fixedly disposed on the moving platform 4, and the second motor 14 is fixedly mounted on the mounting plate 15, and its drive shaft is connected to the transmission worm gear 13 through a transmission shaft 16. The inner circumferential wall of the transmission turbine 12 is provided with an internal thread, and the outer circumferential wall of the lifting rod 9 is provided with an external thread that matches the internal thread of the transmission turbine 12, thereby enabling the lifting rod 9 to be threadedly connected to the central hole of the transmission turbine 12. Both the moving platform 4 and the vertical transmission cylinder 10 are provided with through holes for the lifting rod 9 to pass through. When the second motor 14 drives the transmission worm 13 to rotate, the transmission turbine 12 rotates due to the meshing action between the transmission worm 13 and the transmission turbine 12. Because of the threaded connection between the transmission turbine 12 and the lifting rod 9, the rotation of the transmission turbine 12 causes the lifting rod 9 to move linearly along its axial direction (i.e., the vertical direction).

[0026] The lifting rod 9 passes through the clearance groove 3 and has a horizontal lifting seat 17 fixedly installed at its lower end. A knotter 18 is installed on the lifting seat 17. In addition, a limiting head 19 is fixedly installed at the upper end of the lifting rod 9. The outer diameter of the limiting head 19 is larger than the inner diameter of the through hole on the top plate of the vertical transmission cylinder 10.

[0027] In application, the twister can be aligned with the slotted drum station of the winding machine where yarn splicing is required. When other slotted drum stations need to splice yarn, two first motors can be turned on. Under the meshing transmission of two sets of transmission gears and transmission racks, the moving table and the twister can be moved horizontally and linearly to the corresponding slotted drum station. Therefore, by configuring a single twister, the yarn splicing needs of multiple slotted drum stations of the winding machine can be met, thereby reducing the supporting cost of the winding machine equipment. In addition, a single twister is easy to debug and maintain, effectively reducing labor and time costs.

[0028] In addition, this utility model can use the transmission action of the second motor, the transmission worm gear and the transmission turbine to make the lifting rod drive the knotter on the lifting seat to move linearly in the vertical direction, so as to realize convenient adjustment of the height of the knotter and thus meet the working comfort of workers of different heights.

[0029] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
