A yarn tensioning device based on a spinning machine

Abstract

This utility model discloses a yarn tensioning device based on a spinning machine, relating to the field of spinning machine technology. It includes a mounting plate and a first tensioning wheel rotatably connected to the side of the mounting plate. An adjustment assembly is mounted on the other side of the mounting plate, and a second tensioning wheel is rotatably connected to the side of the adjustment assembly. The second tensioning wheel is movable on one side of the mounting plate via the adjustment assembly. This yarn tensioning device, based on a spinning machine, uses a motor to drive a second threaded rod to rotate, causing a second threaded cap, which is threadedly engaged with the second threaded rod, to move axially along the second threaded rod. The second threaded cap drives a connecting block to move within a movable groove on the surface of the mounting plate. The connecting block then drives the second tensioning wheel to move, changing the position of the second tensioning wheel relative to the first tensioning wheel. This allows for real-time adjustment of the yarn path length and wrap angle, maintaining the required tension and ensuring that the yarn always contacts the tensioning wheel surface with appropriate pressure.

Description

Technical Field

[0001] This utility model relates to a tensioning device, specifically a yarn tensioning device based on a spinning machine, belonging to the field of spinning machine technology. Background Technology

[0002] A spinning machine is a machine that conveys and winds yarn into neat and orderly cones. When conveying and winding yarn, the spinning machine needs to wind the yarn under tension. This is usually achieved through a tensioning structure. Existing tensioning structures allow for simultaneous adjustment of two sets of tensioning rollers, increasing the friction between the yarn and the tensioning rollers during tensioning and conveying. This further tightens the conveying mechanism, ensuring stable winding and conveying when the tensioning structure is fixedly installed on the spinning machine, thus improving the conveying efficiency of the yarn during tensioning and winding.

[0003] When existing tensioning structures are installed on spinning machines for tensioning and winding, prolonged conveying of the yarn on the outer surface of the tensioning wheel can easily cause friction damage to the outer surface of the tensioning wheel. Continuing to wind the yarn reduces friction, causing the yarn to slip on the outer surface of the tensioning wheel while it is under tension. This makes it difficult to drive the tensioning wheel to rotate and convey the yarn. Furthermore, internal friction damage to the tensioning wheel makes replacement inconvenient and wastes materials. Therefore, the tensioning structure installed on the spinning machine affects both the conveying efficiency and the ease of replacement when tensioning and winding the yarn.

[0004] Therefore, a yarn tensioning device based on a spinning machine is proposed here. Utility Model Content

[0005] This invention proposes a yarn tensioning device based on a spinning machine to solve the problems in the prior art where, when the yarn is conveyed on the outer surface of the tensioning wheel for a long time, the outer surface of the tensioning wheel is easily damaged by friction, causing the yarn to slip on the outer surface of the tensioning wheel, making it difficult to drive the tensioning wheel to rotate and convey the yarn; at the same time, it is also difficult to replace the tensioning wheel.

[0006] This utility model is achieved through the following technical solution: a yarn tensioning device based on a spinning machine, including a mounting plate and a first tensioning wheel rotatably connected to the side of the mounting plate, an adjustment component is mounted on the other side of the mounting plate, a second tensioning wheel is rotatably connected to the side of the adjustment component, and the second tensioning wheel moves on one side of the mounting plate through the adjustment component;

[0007] The adjustment assembly includes a support plate fixed to the side of the mounting plate, a motor fixed to the side of the support plate, a second threaded rod fixed to the output end of the motor, a second threaded cap threaded to the surface of the second threaded rod, a connecting block fixed to the side of the second threaded cap, and a movable groove opened on the surface of the mounting plate, with one end of the connecting block passing through the movable groove.

[0008] Furthermore, the second tensioning wheel includes a rotating plate rotatably connected to the side of the mounting plate, the other end of the connecting block being rotatably connected to the side of the rotating plate, a mounting block being provided on one side of the rotating plate, a placement groove being provided on the side of the mounting plate, a knob being provided inside the placement groove, a first threaded rod being fixed to the side of the knob, a transmission chamber being provided on the side of the mounting block, the other end of the first threaded rod being rotatably inserted into the transmission chamber, and a fixing plate being rotatably connected to the other end of the first threaded rod.

[0009] Furthermore, an elastic block is fixed to the side of the rotating plate, and a slot corresponding to the elastic block is opened on the side of the fixed plate. The elastic block is engaged inside the slot, and the end face of the elastic block is an arc-shaped surface.

[0010] Furthermore, a pressure rod passes through the surface of the knob and the first threaded rod, and a top rod passes through the inside of the fixing plate. The top rod is perpendicular to the pressure rod and the elastic block, respectively. The contact surfaces of the top rod and the pressure rod are both inclined surfaces, and the pressure rod can push the top rod to move vertically.

[0011] Furthermore, the first threaded rod has a first threaded cap threadedly connected to its surface, a first connecting rod hinged to its upper surface, a fixing rod hinged to its other end, a second connecting rod symmetrical to the first connecting rod hinged to its lower surface, and the other end of the second connecting rod hinged to the side of the fixing plate. The rotating plate has a fixing groove corresponding to the fixing rod on its side, and one end of the fixing rod is engaged inside the fixing groove. The fixing rod is L-shaped, and there are multiple sets of the first connecting rod, the fixing rod, and the second connecting rod, which are evenly arranged in a ring around the outer periphery of the first threaded cap.

[0012] Furthermore, the first tensioning wheel and the second tensioning wheel have the same structure, and both surfaces are covered with yarn. The first tensioning wheel and the second tensioning wheel are arranged in a "Z" shape.

[0013] Furthermore, the height of the fixing rod is higher than that of the rotating plate, and the surface of the rotating plate is provided with a protective pad of the same height as the fixing rod, with the fixing rod and the protective pad being flush.

[0014] This invention provides a yarn tensioning device based on a spinning machine, which has the following beneficial effects:

[0015] 1. This yarn tensioning device based on a spinning machine drives the second threaded rod to rotate via a motor, causing the second threaded cap, which is threadedly engaged with the second threaded rod, to move axially along the second threaded rod. The second threaded cap drives the connecting block to move within the movable groove on the surface of the mounting plate. The connecting block drives the second tensioning wheel to move, changing the position of the second tensioning wheel relative to the first tensioning wheel. This allows for real-time adjustment of the yarn path length and wrap angle, maintaining the required tension. Consequently, the yarn always contacts the tensioning wheel surface with appropriate pressure, providing sufficient frictional driving force to prevent slippage while avoiding excessive pressure that leads to premature wear.

[0016] 2. This yarn tensioning device based on a spinning machine rotates a knob to drive the first threaded rod to rotate. The first threaded rod drives the first threaded cap to move, and the first threaded cap drives the first connecting rod hinged to its outer surface to move. In conjunction with the second connecting rod hinged to the side of the fixed plate, it can push the fixed rod to move, thereby removing one end of the fixed rod from the fixed groove. Then, it pushes the pressure rod. Since the contact surface between the pressure rod and the top rod is an inclined surface, the pressure rod can push the top rod to move, thereby pushing the elastic locking block to move and separating the elastic locking block from the locking groove. The fixed block can then be removed from the surface of the rotating block, and the worn fixed block and the worn protective pad can be replaced to maintain a sufficient coefficient of friction between the wheel surface and the yarn and prevent the yarn from slipping due to the smooth wheel surface.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0027] Please see Figures 1-4 The present invention proposes the following implementation scheme: A yarn tensioning device based on a spinning machine includes a mounting plate 1 and a first tensioning wheel 2 rotatably connected to the side of the mounting plate 1. An adjustment assembly 3 is mounted on the other side of the mounting plate 1. A second tensioning wheel 4 is rotatably connected to the side of the adjustment assembly 3, and the second tensioning wheel 4 is movable on one side of the mounting plate 1 through the adjustment assembly 3. The adjustment assembly 3 includes a support plate 301 fixed to the side of the mounting plate 1. A motor 302 is fixed to the side of the support plate 301. A second threaded rod 303 is fixed to the output end of the motor 302. A second threaded cap 304 is threadedly connected to the surface of the second threaded rod 303. A connecting block 305 is fixed to the side of the second threaded cap 304. A movable groove 101 is opened on the surface of the mounting plate 1. The connecting block 305... 5 One end is inserted into the movable groove 101; the yarn tensioning device based on the spinning machine drives the second threaded rod 303 to rotate through the motor 302, so that the second threaded cap 304, which is threadedly engaged with the second threaded rod 303, moves along the axial direction of the second threaded rod 303. The second threaded cap 304 drives the connecting block 305 to move in the movable groove 101 opened on the surface of the mounting plate 1. The connecting block 305 drives the second tensioning wheel 4 to move, so that the position of the second tensioning wheel 4 changes relative to the first tensioning wheel 2, thereby adjusting the yarn path length and wrap angle in real time, maintaining the required tension, so that the yarn always contacts the tensioning wheel surface with appropriate pressure, providing sufficient friction driving force to prevent slippage, and avoiding excessive pressure that leads to premature wear.

[0028] Please refer to this carefully. Figure 3 and Figure 4The second tensioning wheel 4 includes a rotating plate 201 rotatably connected to the side of the mounting plate 1, and a connecting block 305 rotatably connected to the side of the rotating plate 201 at the other end. A mounting block 202 is provided on one side of the rotating plate 201. A placement groove 2021 is provided on the side of the mounting plate 1, and a knob 203 is provided inside the placement groove 2021. A first threaded rod 204 is fixed to the side of the knob 203. A transmission chamber 2022 is provided on the side of the mounting block 202. The other end of the first threaded rod 204 rotatably passes through the transmission chamber 2022, and the other end of the first threaded rod 204 is rotatably connected to a fixing plate 209. An elastic locking block 2012 is fixed to the side of the rotating plate 201, and a connection is provided on the side of the fixing plate 209 to the elastic locking block 2012. Correspondingly, in the slot 2091, the elastic block 2012 is engaged inside the slot 2091, and the end face of the elastic block 2012 is an arc-shaped surface; a pressure rod 210 passes through the surface of the knob 203 and the first threaded rod 204, and a top rod 211 passes through the inside of the fixing plate 209. The top rod 211 is perpendicular to the pressure rod 210 and the elastic block 2012 respectively. The contact surfaces of the top rod 211 and the pressure rod 210 are both inclined surfaces, and the pressure rod 210 can push the top rod 211 to move vertically; a first threaded cap 205 is threadedly connected to the surface of the first threaded rod 204, and a first connecting rod 206 is hinged to the upper surface of the first threaded cap 205. A fixing rod 207 is hinged to the other end of the first connecting rod 206. The fixing rod 207 is shown in the lower table. A second connecting rod 208, symmetrical to the first connecting rod 206, is hinged to the side of the fixed plate 209. The other end of the second connecting rod 208 is hinged to the side of the fixed plate 209. A fixing groove 2011, corresponding to the fixed rod 207, is opened on the side of the rotating plate 201. One end of the fixed rod 207 is engaged inside the fixing groove 2011. The fixed rod 207 is L-shaped, and there are multiple sets of the first connecting rod 206, the fixed rod 207, and the second connecting rod 208, which are evenly arranged in a ring around the outer periphery of the first threaded cap 205. This yarn tensioning device based on a spinning machine rotates the first threaded rod 204 by turning the knob 203. The first threaded rod 204 drives the first threaded cap 205 to move, and the first threaded cap 205 drives the hinge... The first connecting rod 206 attached to its outer surface moves, cooperating with the second connecting rod 208 hinged to the side of the fixed plate 209, which can push the fixed rod 207 to move, thereby removing one end of the fixed rod 207 from the fixed groove 2011. Then, the pressure rod 210 is pushed. Since the contact surface between the pressure rod 210 and the top rod 211 is an inclined surface, the pressure rod 210 can push the top rod 211 to move, thereby pushing the elastic locking block 2012 to move, so that the elastic locking block 2012 separates from the locking groove 2091. The fixed block can then be removed from the surface of the rotating block, and the worn fixed block and the worn protective pad can be replaced to maintain a sufficient coefficient of friction between the wheel surface and the yarn, and prevent the yarn from slipping due to the smoothness of the wheel surface.

[0029] Please refer to this carefully. Figure 1 and Figure 2The first tensioning roller 2 and the second tensioning roller 4 have the same structure and are both covered with yarn. The first tensioning roller 2 and the second tensioning roller 4 are arranged in a "Z" shape. The height of the fixing rod 207 is higher than that of the rotating plate 201. The surface of the rotating plate 201 is provided with a protective pad of the same height as the fixing rod 207. The fixing rod 207 and the protective pad are flush. The "Z" shaped winding of the yarn on the first tensioning roller 2 and the second tensioning roller 4 naturally increases the effective contact area and wrap angle, improves the upper limit of friction, and further enhances the anti-slip ability.

[0030] In use, the device is first installed on a spinning machine and connected to the machine's control equipment and power supply. When the tension of the tension wheel needs to be adjusted, the operator controls the motor 302 via the control equipment. The motor 302 drives the second threaded rod 303 to rotate, causing the second threaded cap 304, which is threadedly engaged with the second threaded rod 303, to move axially along the second threaded rod 303. The second threaded cap 304 drives the connecting block 305 to move within the movable groove 101 on the surface of the mounting plate 1. The connecting block 305 drives the second tension wheel 4 to move, changing its position relative to the first tension wheel 2. This allows for real-time adjustment of the yarn path length and wrap angle, maintaining the required tension and ensuring that the yarn always contacts the tension wheel surface with appropriate pressure.

[0031] When it is necessary to replace the worn tension wheel, the operator only needs to turn the knob 203 to rotate the first threaded rod 204. The first threaded rod 204 drives the first threaded cap 205 to move. The first threaded cap 205 drives the first connecting rod 206, which is hinged to its outer surface, to move. In conjunction with the second connecting rod 208, which is hinged to the side of the fixing plate 209, the fixing rod 207 can be pushed to move, thereby removing one end of the fixing rod 207 from the fixing groove 2011. Then, the operator pushes the pressure rod 210. Since the contact surface between the pressure rod 210 and the top rod 211 is inclined, the pressure rod 210 can push the top rod 211 to move, thereby pushing the elastic locking block 2012 to move, so that the elastic locking block 2012 separates from the locking groove 2091. The operator can then remove the fixing block from the surface of the rotating block and replace the worn fixing block and the worn protective pad to maintain a sufficient coefficient of friction between the wheel surface and the yarn.
