Description

Technical Field

[0001] This invention belongs to the field of textile technology, and specifically relates to an adjustable automatic yarn take-up and untake-up device. Background Technology

[0002] In the textile processing, the yarn used as raw material needs to be transported. Existing devices cannot make the yarn evenly wound on the curved side of the spinning spool during the winding process, and cannot ensure that the yarn thickness is the same when the spinning spool is retracted. During the winding and unwinding of the yarn, the yarn segments are prone to tangling due to being too loose.

[0003] Based on the above, there is a need for an adjustable automatic yarn winding and unwinding device that can make the yarn evenly wound on the curved side of the spinning spool, so that the yarn thickness is the same when the spinning spool is retracted. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an adjustable automatic yarn winding and unwinding device, which solves the problems of existing devices being unable to make the yarn evenly wound on the curved side of the spinning spool and unable to make the yarn of uniform thickness when the spinning spool is retracted.

[0005] The purpose and effectiveness of the adjustable automatic yarn take-up and untake-up device of the present invention are achieved by the following specific technical means:

[0006] An adjustable automatic yarn feeding and unloading device includes a fixed platform; a servo motor is fixedly connected to the bottom of the fixed platform; a one-way bearing is hinged to the top of the fixed platform, and a spinning shaft is coaxially connected to the top of the inner ring of the one-way bearing; the top of the servo motor shaft is coaxially connected to the bottom of the outer ring of the spinning shaft, and a transmission gear is coaxially connected to the middle of the servo motor shaft; a front bracket is fixedly connected to the front end of the fixed platform, and two sets of front brackets are provided; a bevel gear shaft is hinged to the right side of the front bracket, and bevel gears are coaxially connected to the front and rear ends of the bevel gear shaft; a vertical shaft is hinged to the bottom of the fixed platform; a guide roller is hinged to the inner side of the front end of the front bracket, and a side gear is coaxially connected to the right side of the guide roller, with two sets of side gears meshing with each other; a linkage bevel gear is coaxially connected to the right end of the side gear, and the right side of the linkage bevel gear meshes with the front end of the bevel gear shaft for transmission.

[0007] Furthermore, a bevel gear A is coaxially connected inside the vertical shaft, and a driven gear is coaxially connected at the bottom of the vertical shaft, with the driven gear meshing with the transmission gear for transmission.

[0008] Furthermore, a reciprocating screw is fixedly connected to the top right side of the front bracket, and a control unit is fixedly connected to the top of the reciprocating screw.

[0009] Furthermore, a side bracket is fixedly connected to the right end of the reciprocating ball screw ball nut seat, and a sliding rheostat coil is fixedly connected to the top and bottom of the side bracket. The number of sliding rheostat coils is set to two sets.

[0010] Furthermore, a top crossbeam is fixedly connected to the top right side of the side bracket, and a circular through hole is vertically penetrating the inside of the top crossbeam. A return spring A is fixedly connected to the outer side of the bottom of the circular through hole.

[0011] Furthermore, the bottom of the reset spring A is fixedly connected to a base frame, and a wire-bearing wheel A is provided on the inner side of the bottom of the base frame through a hinge. The wire-bearing wheel A is an hourglass-shaped structure that is thick at both ends and thin in the middle. A sliding rod A is fixedly connected to the top of the base frame. The sliding rod A is fixedly connected to the inner side of the circular through hole. A sliding piece A is fixedly connected to the top of the sliding rod A. The left side of the sliding piece A is slidably connected to the curved side of the sliding rheostat coil.

[0012] Furthermore, a bottom crossbar is fixedly connected to the bottom right side of the side bracket, and a circular through hole is vertically penetrating inside the bottom crossbar. A return spring B is fixedly connected to the outer side of the top of the circular through hole.

[0013] Furthermore, the top of the reset spring B is fixedly connected to a transverse channel frame, the inner side of the transverse channel frame is fixedly connected to a sliding groove, the bottom of the base frame is slidably connected to the inner side of the sliding groove of the transverse channel frame, the top inner side of the transverse channel frame is provided with a wire-bearing wheel B by a hinge, the bottom of the transverse channel frame is fixedly connected to a sliding rod B, the top of the sliding rod B is fixedly connected to a sliding piece B, and the left side of the sliding piece B is slidably connected to the curved side of the sliding rheostat coil.

[0014] The present invention has at least the following beneficial effects:

[0015] 1. By setting up a yarn-bearing wheel A, when synchronously retracting the spun yarn, the control unit controls the reciprocating screw to rotate, causing its ball bearing nut seat to drive the yarn-bearing wheel A and the yarn-bearing wheel B to move vertically back and forth. This allows the yarn head to move vertically back and forth during the rotation of the spinning shaft, so that the yarn can be evenly wound on the curved side of the spinning shaft, and the thickness of the yarn can be the same when the spinning shaft retracts the yarn.

[0016] 2. This invention, by setting a side support, allows the yarn to pass through the inner sides of the receiving rollers A and B during the spinning process, enabling them to receive the middle of the yarn. When the connection point is at the bottom of the spinning shaft, the yarn presses down on the top of the receiving roller A, causing the receiving roller A to move the base frame downwards. This, in turn, causes the base frame to move the top sliding rod A downwards, resulting in the sliding plate A at the top of the sliding rod A sliding downwards. The current is detected by the sliding rheostat coil located at the top, and then detected by the control unit to control the reciprocating yarn. The lever operation allows the reciprocating screw ball nut seat to move downwards. When the thread bearing wheel B is compressed, the sliding plate B slides against a set of sliding rheostat coils at the bottom. After the control unit detects the current signal, it controls the reciprocating screw to move, causing the ball nut seat to move the thread bearing wheel A or B to the height where the sliding rheostat coil current resets, and then stops. This ensures that the thread bearing wheels A and B always maintain stable support and tension for the middle section of the yarn, preventing the yarn from tangling due to excessive slack when retracting and releasing the yarn.

[0017] 3. By setting up a guide roller, when the yarn is being retracted, the control unit controls the servo motor to rotate in the opposite direction. This allows the servo motor to drive the one-way bearing, which is coaxial with the spindle shaft, to rotate. The one-way bearing then drives the spinning shaft, which is coaxial with the top of the spindle shaft, to rotate. Through gear transmission, the guide roller rotates synchronously during the rotation of the spinning shaft, thus enabling the yarn to be retracted synchronously. Attached Figure Description

[0032] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "fixing," "screw connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] like Figures 1 to 5As shown, this embodiment of the invention provides an adjustable automatic yarn feeding and take-up device, including a fixed platform 1; a servo motor 2 is fixedly connected to the bottom of the fixed platform 1; a one-way bearing 101 is hinged to the top of the fixed platform 1, and a spinning shaft 102 is coaxially connected to the top of the inner ring of the one-way bearing 101; the top of the servo motor 2 shaft is coaxially connected to the bottom of the outer ring of the spinning shaft 102, and a transmission gear 201 is coaxially connected to the middle of the servo motor 2 shaft; a front support 103 is fixedly connected to the front end of the fixed platform 1, and two sets of front supports 103 are provided; a bevel gear shaft 1031 is hinged to the right side of the front support 103; a vertical shaft 3 is hinged to the bottom of the fixed platform 1, and a guide roller 1032 is hinged to the inner side of the front end of the front support 103, and two sets of guide rollers 1032 are provided; a side gear 1033 is coaxially connected to the right side of the guide roller 1032, and two sets of side gears 1033 are provided. The two gears 1033 mesh with each other. The right end of the side gear 1033 is coaxially connected to a linkage bevel gear 1034. The right side of the linkage bevel gear 1034 meshes with the front end of the bevel gear shaft 1031 for transmission. When it is necessary to send the wire outward, the control unit 405 controls the servo motor 2 to run. This allows the servo motor 2 to rotate, which in turn drives the transmission gear 201 connected to it to rotate. The transmission gear 201 drives the driven gear 302 meshing with it on the right side to rotate. The driven gear 302 drives the bevel gear A301 coaxially at its bottom to rotate, which in turn drives the bevel gear shaft 1031 meshing with it to rotate. The bevel gear at the front end of the bevel gear shaft 1031 drives the linkage bevel gear 1034 meshing with it to rotate. This allows the linkage bevel gear 1034 to drive the side gear 1033 coaxially with it to rotate. This allows the two sets of meshing side gears 1033 to rotate in opposite directions, which in turn drives the wire end held on its inner side to be transmitted outward.

[0036] like Figures 1 to 5 As shown, a bevel gear A301 is coaxially connected inside the vertical shaft 3, and a driven gear 302 is coaxially connected at the bottom of the vertical shaft 3. The driven gear 302 meshes with the transmission gear 201 for transmission. When the spun yarn is being retracted, the servo motor 2 is controlled to rotate in the reverse direction by the control unit 405. This allows the servo motor 2 to drive the one-way bearing 101, which is coaxial with its rotating shaft, to rotate. The one-way bearing 101 can then drive the spinning shaft 102, which is coaxial with its top, to rotate. Through gear transmission, the spinning shaft 102 can rotate synchronously, causing the guide roller 1032 to rotate synchronously, thus enabling the synchronous retraction of the spun yarn.

[0037] like Figures 1 to 5As shown, a reciprocating screw 4 is fixedly connected to the top right side of the front bracket 103. A control unit 405 is fixedly connected to the top of the reciprocating screw 4. The control unit 405 is electrically connected to the servo motor 2. A side bracket 401 is fixedly connected to the right end of the ball nut seat of the reciprocating screw 4. A sliding rheostat coil 402 is fixedly connected to the top and bottom of the side bracket 401. The number of sliding rheostat coils 402 is set to two sets. A top crossbeam 403 is fixedly connected to the top right side of the side bracket 401. A circular through hole is vertically penetrating inside the top crossbeam 403. A return spring A4031 is fixedly connected to the outer bottom of the circular through hole. A base frame 4032 is fixedly connected to the bottom of the return spring A4031. A wire-bearing wheel A4033 is hinged to the inner bottom of the base frame 4032. 4033 is an hourglass-shaped structure, thicker at both ends and thinner in the middle. A sliding rod A4034 is fixedly connected to the top of the base frame 4032. The sliding rod A4034 is fixedly connected to the inside of a circular through-hole. A sliding piece A4035 is fixedly connected to the top of the sliding rod A4034. The left side of the sliding piece A4035 is slidably connected to the curved side of the sliding rheostat coil 402. A bottom crossbar 404 is fixedly connected to the bottom right side of the side bracket 401. A circular through-hole is vertically penetrating the bottom of the bottom crossbar 404. A return spring B4041 is fixedly connected to the outer top of the circular through-hole. A horizontal through-slot 4043 is fixedly connected to the top of the return spring B4041. A sliding groove is fixedly connected to the inner side of the horizontal through-slot 4043. The bottom of the base frame 4032 is slidably connected to the inner side of the sliding groove of the horizontal through-slot 4043. A thread-bearing wheel B4044 is hinged to the inner top of the 4043. A sliding rod B4042 is fixedly connected to the bottom of the transverse channel frame 4043. A sliding plate B4045 is fixedly connected to the top of the sliding rod B4042. The left side of the sliding plate B4045 is slidably connected to the curved side of the sliding rheostat coil 402. During the spinning process, by passing the thread through the inner sides of the thread-bearing wheel A4033 and the thread-bearing wheel B4044, the thread can be supported in the middle of the spinning thread. When the connection point is at the bottom of the spinning shaft 102, the spinning thread presses down on the top of the thread-bearing wheel A4033, which causes the thread-bearing wheel A4033 to drive the base frame 4032 to move downward. This causes the base frame 4032 to drive the sliding rod A4034 at its top to move downward, thereby allowing the top of the sliding rod A4034 to slide downward. Sliding plate A4035 slides downwards. After the current is detected by the sliding rheostat coil 402 located at the top, and then detected by the control unit 405, the control unit controls the reciprocating screw 4 to rotate. This causes the ball nut seat of the reciprocating screw 4 to move downwards. When the yarn receiving wheel B4044 is pressed, the sliding plate B4045 slides against a set of sliding rheostat coils 402 at the bottom. After the control unit 405 detects the current signal, it controls the reciprocating screw 4 to rotate, causing the ball nut seat to move the yarn receiving wheel A4033 or yarn receiving wheel B4044 to the height where the current of the sliding rheostat coil 402 resets, and then stops rotating. This ensures that the yarn receiving wheels A4033 and B4044 always maintain stable support and tension for the middle section of the yarn.This design prevents the yarn segment from tangling due to excessive slack during the retraction and release of the yarn. During synchronous retraction of the spun yarn, the control unit 405 controls the reciprocating screw 4 to rotate, causing its ball bearing nut seat to drive the yarn-bearing wheels A4033 and B4044 in a vertical reciprocating motion. This allows the yarn end to move vertically and reciprocally during the rotation of the spinning shaft 102, ensuring the yarn is evenly wound on the curved side of the spinning shaft 102 and that the yarn thickness is uniform when the spinning shaft 102 retracts the yarn.

[0038] The specific usage and function of this embodiment are as follows:

[0039] In this invention, when external wiring is required, the servo motor 2 is controlled by the control unit 405 to rotate. This causes the servo motor 2's shaft to drive the coaxially connected transmission gear 201 to rotate. The transmission gear 201 then drives the driven gear 302 meshing with it on its right side to rotate. The driven gear 302, in turn, drives the bevel gear A301 coaxially at its bottom to rotate, which in turn drives the bevel gear shaft 1031 meshing with it to rotate. The bevel gear at the front end of the bevel gear shaft 1031 drives the meshing linked bevel gear 1034 to rotate, which in turn drives the coaxial side gear 1033 to rotate. This allows the two sets of meshing side gears 1033 to... Rotation in the opposite direction allows the yarn end held on its inner side to be transmitted outward. When the yarn is being retracted, the servo motor 2 is controlled to rotate in the opposite direction by the control unit 405. This causes the one-way bearing 101, which is coaxial with the spindle shaft, to rotate. The one-way bearing 101 then drives the spinning shaft 102, which is coaxial with its top, to rotate. Through gear transmission, the spinning shaft 102 rotates synchronously, causing the guide roller 1032 to rotate synchronously, thus retracting the yarn synchronously. The reciprocating screw 4 is controlled by the control unit 405 to rotate, causing the ball bearing nut seat to drive the yarn receiving rollers A4033 and B4044 to move vertically and reciprocally. This allows the spinning shaft 102 to rotate during its rotation. The vertical reciprocating movement of the thread end allows the yarn to be evenly wound on the curved side of the spinning shaft 102, ensuring a uniform thickness when the spinning shaft 102 retracts the yarn. During the yarn feeding process, by passing the yarn through the inner sides of the receiving rollers A4033 and B4044, the middle of the yarn can be received. When the connection point is at the bottom of the spinning shaft 102, the yarn presses down on the top of the receiving roller A4033, causing the receiving roller A4033 to drive the base frame 4032 downwards. This, in turn, causes the base frame 4032 to drive the top slide rod A4034 downwards, resulting in the sliding plate A4035 at the top of the slide rod A4034 sliding downwards. The current is detected by the sliding rheostat coil 402 located at the top. After detection by the control unit 405, the reciprocating screw 4 is controlled to rotate, causing the ball nut seat of the reciprocating screw 4 to move downwards. When the yarn bearing wheel B4044 is pressed, the slider B4045 slides against a set of sliding rheostat coils 402 at the bottom. After the control unit 405 detects the current signal, it controls the reciprocating screw 4 to rotate, causing the ball nut seat to move the yarn bearing wheel A4033 or yarn bearing wheel B4044 to the height where the current of the sliding rheostat coil 402 is reset, and then stops rotating. This ensures that the yarn bearing wheels A4033 and B4044 always maintain stable support and tension for the middle section of the yarn, preventing the yarn from tangling due to excessive slack when retracting and releasing the yarn.
