Tension control device for winding of spinning frame

Abstract

The utility model discloses a tension control device for winding of a spinning frame, which comprises a frame, a front limit block and a rear limit block are mounted on the frame, two guide shafts are rotatably connected onto the front limit block and the rear limit block, two adjusting mechanisms are arranged on the frame and are in central symmetry on the frame, and the two guide shafts are rotatably connected onto the front limit block and the rear limit block. The adjusting mechanism comprises a linear actuator. Through central symmetry of the adjusting mechanism, the linear actuator can drive the adjusting block to move in the opposite direction, so that spun yarn blocked by the adjusting shaft on the adjusting block is driven to be subjected to tension adjustment in two directions, and finally the adjusting range of spun yarn tension control is widened; when the linear actuator pushes the adjusting block to the edge of the rack, that is, when the tension of the spun yarn is increased to the maximum adjusting limit, the rotating speed of the adjusting shaft pulled by the spun yarn to rotate is reduced through meshing of the first gear and the second gear, and therefore the tension of the spun yarn is further increased through friction between the adjusting shaft and the spun yarn.

Description

Technical Field

[0001] The utility model relates to the technical field of winding tension control of a spinning frame, in particular to a winding tension control device for a spinning frame. Background Art

[0002] The spinning frame is a spinning machine that draws, twists and winds semi-finished roving or sliver into spinning tubes during the spinning process. The shaping of the spun yarn on the bobbin relies on the up and down movement of the steel collar plate to make the spun yarn evenly wound on the bobbin, so that it can form a certain shape.

[0003] In the prior art, when winding the yarn, that is, winding the yarn onto a yarn tube for collection and use, a tension control device is required to adjust the tension of the yarn to prevent the yarn from breaking during collection. However, the existing tension control device has a small adjustment range for the yarn tension and is difficult to apply to the winding and collection of yarns of different specifications. Therefore, it is necessary to design a tension control device for winding a spinning machine. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model provides a tension control device for winding a spinning machine, comprising a frame, the frame is equipped with a front limit block and a rear limit block, the front limit block and the rear limit block are rotatably connected to two guide shafts, the frame is provided with two adjustment mechanisms, the two adjustment mechanisms are centrally symmetrically arranged on the frame, the adjustment mechanism comprises a linear actuator, the linear actuator is mounted on the frame, an adjustment block is mounted on the output end of the linear actuator, two adjustment shafts are rotatably connected to the adjustment block, a gear 1 is mounted on the adjustment shaft, a gear 2 is rotatably connected to the adjustment block, the two gears 1 are located on both sides of the gear 2 and are meshed with the gear 2; the adjustment mechanism also comprises a friction block, the friction block is mounted on the frame, and the friction block is matched with the adjustment shaft on the adjustment block away from the linear actuator side.

[0006] Preferably, the friction block is provided with an arc groove, and the diameter of the arc groove is the same as the diameter of the adjustment shaft.

[0007] Preferably, an annular wear-resistant ring is installed on the adjustment shaft on the side of the adjustment block away from the linear actuator, and the diameter of the arc groove is the same as the diameter of the annular wear-resistant ring.

[0008] Preferably, two slide grooves are provided on the frame, and a slider is installed at the bottom of the adjustment block, and the slider slides in the slide groove.

[0009] Preferably, the frame is provided with a plurality of mounting holes.

[0010] Preferably, a card slot is provided on the frame, a card block is mounted on the friction block, and the card block is card-engaged with the card slot.

[0011] Compared with the prior art, this technical solution has at least one of the following beneficial effects:

[0012] Through the central symmetric arrangement of the adjustment mechanism, the linear actuator can drive the adjustment block to move in opposite directions, thereby driving the yarn blocked by the adjustment shaft on the adjustment block to adjust the tension in two directions, ultimately increasing the adjustment range of the yarn tension control;

[0013] When the linear actuator pushes the adjustment block to the edge of the frame, that is, when the tension of the yarn is increased to the maximum adjustment limit, the rotation speed of the adjustment shaft pulled by the yarn is reduced through the meshing of gear 1 and gear 2, thereby further increasing the tension of the yarn through the friction between the adjustment shaft and the yarn.

DETAILED DESCRIPTION

[0019] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0020] See also Figures 1 to 4The embodiment of the present application provides a tension control device for winding a spinning machine, comprising a frame 1, on which a front limit block 2 and a rear limit block 3 are installed, and two guide shafts 4 are rotatably connected to the front limit block 2 and the rear limit block 3. Two adjusting mechanisms are provided on the frame 1, and the two adjusting mechanisms are centrally symmetrically arranged on the frame 1. The adjusting mechanism comprises a linear actuator 5, which can be an electric cylinder. The linear actuator 5 is installed on the frame 1, and an adjusting block 6 is installed at the output end of the linear actuator 5. Two adjusting shafts 7 are rotatably connected to the adjusting block 6, and a gear 1 8 is installed on the adjusting shaft 7. A gear 2 9 is rotatably connected to the adjusting block 6, and the two gears 1 8 are located on both sides of the gear 2 9 and are meshed with the gear 2 9; the adjusting mechanism also comprises a friction block 10, which is installed on the frame 1, and the friction block 10 is matched with the adjusting shaft 7 on the adjusting block 6 away from the side of the linear actuator 5.

[0021] In this embodiment, the spun yarn passes between the two guide shafts 4 on the front limit block 2, then passes between the two adjustment shafts 7 on the two sets of centrally symmetrically arranged adjustment blocks 5, and finally passes out from between the two guide shafts 4 on the rear limit block 3. When the tension of the yarn is adjusted, the linear actuator 5 in the two sets of adjusting mechanisms arranged symmetrically push the adjusting block 6, so that the adjusting shaft 7 close to the linear actuator 5 of the two adjusting shafts 7 abuts against the yarn and pushes it to adjust the tension. The two sets of adjusting mechanisms can push the yarn toward the two sides of the frame 1 respectively, thereby increasing the tension adjustment range of the yarn compared with the general unidirectional tension adjustment mechanism; when the linear actuator 5 pushes the adjusting block 6 to the outermost edge of the frame 1, that is, when the yarn tension is increased to the maximum by pushing and adjusting, the adjusting shaft 7 away from the linear actuator 5 of the two adjusting shafts 7 abuts against and rubs against the friction block 10, thereby transmitting the friction force from the adjusting shaft 7 away from the linear actuator 5 to the other adjusting shaft 7 close to the linear actuator 5 abutting against the yarn through the sequential meshing transmission of gear 1 8, gear 2 9, and gear 1 8, so that the speed of the adjusting shaft 7 driven by the yarn is reduced, thereby further increasing the tension of the yarn through the friction between the adjusting shaft 7 and the yarn.

[0022] In some embodiments, in order to further improve the abutting friction effect between the friction block 10 and the adjusting shaft 7 , an arc groove 11 is provided on the friction block 10 , and the diameter of the arc groove 11 is the same as the diameter of the adjusting shaft 7 .

[0023] In some embodiments, in order to protect the adjustment shaft 7 that cooperates with the friction block 10, an annular wear-resistant ring 12 is installed on the adjustment shaft 7 on the side of the adjustment block 6 away from the linear actuator 5, and the diameter of the arc groove 11 is the same as the diameter of the annular wear-resistant ring 12.

[0024] In some embodiments, in order to facilitate the protection of the linear actuator 5 , two slide grooves 13 are provided on the frame 1 , and a slider 14 is installed at the bottom of the adjustment block 6 , and the slider 14 slides in the slide groove 13 .

[0025] In some embodiments, in order to facilitate installation of the rack 1 at a suitable position, a plurality of installation holes 15 are provided on the rack 1 .

[0026] In some embodiments, in order to facilitate the replacement of the friction block 10, a slot 16 is provided on the frame 1, and a block 17 is installed on the friction block 10, and the block 17 is engaged with the slot 16. The block 17 is L-shaped.
