Description

Technical Field

[0001] The invention belongs to the technical field related to yarn drafting, and in particular relates to a drafting mechanism for polyester yarn production. Background Art

[0002] Yarn drawing is the process of drawing out and thinning the combed fiber aggregate (such as slivers, roving, etc.) to gradually straighten the fibers, eliminate hooks, and make the fiber aggregate reach the predetermined quality. Drawing can straighten and parallelize the fibers, improve the uniformity and strength of the yarn, ensure that the yarn has good physical and mechanical properties, and directly affect the quality of the yarn and the smooth progress of the subsequent weaving process.

[0003] Common yarn drafting devices fix the yarn position and lift the middle position of the yarn to achieve drafting. After the lifting is restored, the yarn position changes, the yarn cannot be straightened, and it is easy to get disordered when winding. In the actual production process, the drafted yarn needs to be waxed to avoid hairiness during the drafting process, which affects subsequent processing and reduces wear.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] For specific embodiment 1, please refer to Figure 1-12The present invention discloses a drafting mechanism for producing polyester yarn, comprising a supporting workbench 1. Specifically, a stretching waxing assembly 2 is fixedly installed on the upper surface of the supporting workbench 1. The stretching waxing assembly 2 comprises a pressing clamp 201 and a limiting pressing plate 202 which can move up and down. The pressing clamp 201 is a horizontal plate structure. The limiting pressing plate 202 is a horizontal plate structure with a limiting groove on the lower surface. A stretching support plate 203 is fixedly connected to the upper surface of the supporting workbench 1. An L-shaped guide groove 204 is symmetrically provided on one side of the stretching support plate 203. A waxing support frame 205 is slidably provided inside the L-shaped guide groove 204. Two waxing blocks 206 are symmetrically provided inside the waxing support frame 205. The side surface of the silk thread is waxed by moving the silk thread or the waxing block 206. The side surface of the stretching support plate 203 slides A stretching transmission frame 207 that can move up and down is dynamically provided, and two stretching transmission connecting rods 208 are symmetrically rotated and connected inside the stretching transmission frame 207. One end of the stretching transmission connecting rod 208 is rotatably connected to a stretching support frame 209 through a first ear plate. The stretching support frame 209 is an arc structure to prevent deviation and slipping during the silk thread drawing process. The stretching support frame 209 fits closely with the corresponding waxing support frame 205. When the stretching support frame 209 moves horizontally, it pushes the corresponding waxing support frame 205 to move horizontally synchronously. A stretching transmission block 210 is fixedly connected to one side of the first ear plate through a horizontal support column. The stretching transmission block 210 interacts with the corresponding L-shaped guide groove 204. Under the sliding cooperation between the stretching transmission block 210 and the L-shaped guide groove 204, the stretching transmission frame 207 moves along an L-shaped trajectory.

[0036] Furthermore, a waxing adjustment component 3 is fixedly connected to the upper surface of the supporting workbench 1, and the waxing adjustment component 3 includes a rotatable transmission disc 301, and a side of the transmission disc 301 is rotatably connected to a plurality of waxing adjustment rollers 302, the yarn is located in the middle position of the plurality of waxing adjustment rollers 302, and the yarn is in contact with the side surfaces of the waxing adjustment rollers 302, the transmission disc 301 drives the waxing adjustment rollers 302 to move synchronously, and at the same time, the waxing adjustment rollers 302 rotate to evenly clean the excess wax blocks on the side surfaces of the yarn.

[0037] Furthermore, a winding assembly 4 is fixedly connected to the upper surface of the supporting workbench 1, and the winding assembly 4 includes a rotatable reciprocating screw rod 401 and a winding roller 402. A winding adjustment block 403 is arranged on the side surface of the reciprocating screw rod 401, and the reciprocating screw rod 401 is adapted to the winding adjustment block 403. A reciprocating spiral groove is provided on the side surface of the reciprocating screw rod 401. A reciprocating transmission bar that slides with the reciprocating spiral groove is fixedly and rotatably connected inside the winding adjustment block 403. As the reciprocating screw rod 401 rotates, the reciprocating transmission bar moves along the trajectory of the reciprocating spiral groove, thereby driving the winding adjustment block 403 to reciprocate, and the silk thread moves reciprocally synchronously, the reciprocating screw rod 401 and the winding roller 402 rotate synchronously, and the winding adjustment block 403 drives the yarn to move reciprocally and evenly wind it on the side surface of the winding roller 402.

[0038] The operation process of this embodiment is as follows: one end of the silk thread is fixed on the winding roller 402. During processing, the silk thread is located between the two waxing blocks 206. During the movement of the silk thread, the waxing block 206 waxes the side surface of the silk thread. Every time the silk thread moves a certain distance, the pressure clamping plate 201 and the limiting pressure plate 202 are controlled to move downward synchronously. The pressure clamping plate 201 clamps and fixes the silk thread. At the same time, the limiting pressure plate 202 limits the movement of the silk thread. Under the rotation of the reciprocating screw rod 401, the stretching transmission frame 207 is driven to move upward, and the stretching transmission connecting rod 208 and the stretching support frame 209 are driven to move upward synchronously. Under the sliding cooperation of the stretching transmission block 210 and the corresponding L-shaped guide groove 204, the stretching transmission block 210 moves vertically upward along the vertical section of the L-shaped guide groove 204, and the stretching support frame 20 9 moves upward synchronously, driving the silk thread to move upward synchronously. Since one end of the silk thread is clamped and fixed by the pressure clamp 201 and the other end is located on the winding roller 402, the silk thread is continuously stretched, and at the same time, the waxing block 206 continues to wax the side surface of the silk thread. When the stretching support frame 209 moves to the horizontal section of the L-shaped guide groove 204, the stretching transmission connecting rod 208 rotates, the stretching support frame 209 moves away from each other in the horizontal direction, and pushes the waxing support frame 205 and the waxing block 206 to move horizontally synchronously. The two waxing support frames 205 move axially along the side surface of the silk thread away from each other, and the waxing block 206 moves synchronously for waxing. The reciprocating screw 401 continues to rotate, causing the stretching transmission frame 207 to move downward, driving the stretching support frame 209 to move closer to each other in the horizontal direction, and then move downward synchronously.

[0039] During this process, the reciprocating screw 401 rotates to drive the transmission disc 301 to rotate, so that the waxing adjustment roller 302 revolves synchronously with the transmission disc 301, and the waxing adjustment roller 302 revolves itself, and the waxing material on the side surface of the positioning silk thread is evenly spread and cleaned, and then the pressure clamp 201 and the limiting pressure plate 202 are controlled to move upward synchronously, so that the silk thread is released, and the reciprocating screw 401 is controlled to rotate to drive the winding adjustment block 403 to move horizontally back and forth, and the winding roller 402 rotates at the same time. Driven by the winding adjustment block 403, the processed silk thread is evenly wound around the side surface of the winding roller 402, and the winding roller 402 winds the silk thread.

[0040] For specific embodiment 2, please refer to Figure 2-9On the basis of the specific embodiment 1, specifically, the surface of the stretching support plate 203 is symmetrically provided with limited guide grooves, the pressing splint 201 and the limited pressure plate 202 slide through the corresponding limited guide grooves, and an adjustment support frame 211 is fixedly connected between the pressing splint 201 and the limited pressure plate 202; the upper surface of the adjustment support frame 211 is symmetrically rotatably connected to the first lifting link 212 through the second ear plate, and one end of the first lifting link 212 is rotatably connected to the second lifting link 213, and the upper surface of the stretching support plate 203 is fixedly connected to the extension support plate, and the second lifting link 213 is rotatably connected to the lower surface of the extension support plate through the third ear plate, and the upper surface of the extension support plate is fixedly installed There is an electric push rod 214, the output shaft of the electric push rod 214 passes through the extended support plate and is fixedly connected to a lifting transmission block 215. The lifting transmission block 215 is symmetrically rotatable on both sides and is connected to a driving link 216. One end of the driving link 216 is rotatably connected to the corresponding first lifting link 212 and second lifting link 213. When the electric push rod 214 drives the lifting transmission block 215 to move up and down, it drives the driving link 216 to rotate, so that the first lifting link 212 and the second lifting link 213 rotate synchronously, and the angle between the two changes. By adjusting the support frame 211, the pressure clamp 201 and the limit pressure plate 202 are driven to move up and down synchronously.

[0041] Furthermore, a side of the stretching support plate 203 away from the adjusting support frame 211 is fixedly connected with a pressure support plate 217 and a limiting support plate 218. The pressure support plate 217 is a horizontal plate-like structure, and the limiting support plate 218 is a plate-like structure with a limiting groove on the upper surface. The pressure support plate 217 and the limiting support plate 218 are respectively located directly below the pressure clamping plate 201 and the limiting pressure plate 202. The silk thread is located on the pressure support plate 217 and the limiting support plate 218. The pressure clamping plate 201 and the pressure support plate 217 cooperate to clamp and fix the silk thread. At the same time, the limiting pressure plate 202 and the limiting support plate 218 fit the side surface of the silk thread to limit the position of the silk thread; a side of the stretching support plate 203 away from the adjusting support frame 211 is provided with a stretching adjustment groove 219. A U-shaped transmission block is slidably arranged inside the stretch adjustment groove 219, one side of the U-shaped transmission block is fixedly connected to the stretch transmission frame 207, and the other side of the U-shaped transmission block is fixedly connected to a transmission guide rail 220, and a transmission adjustment block 221 is slidably arranged inside the transmission guide rail 220; the stretch waxing assembly 2 also includes a driving support plate 222 fixedly connected to the upper surface of the support workbench 1, one side of the driving support plate 222 is rotatably connected to a first transmission wheel 223, one side of the first transmission wheel 223 is fixedly connected to a driving shaft, and one end of the driving shaft passes through the driving support plate 222 and is fixedly connected to a stretch adjustment connecting rod 224, one side of the stretch adjustment connecting rod 224 is fixedly connected to a support shaft, the support shaft is rotatably connected to the transmission adjustment block 221, and the stretch adjustment connecting rod 224 rotates 180° clockwise (such as Figure 5As shown in the figure, the U-shaped transmission block is driven upward by the sliding cooperation between the transmission adjustment block 221 and the transmission guide rail 220, so that the stretching transmission frame 207 moves upward synchronously. When the stretching adjustment connecting rod 224 continues to rotate 180° clockwise, the U-shaped transmission block is driven upward by the sliding cooperation between the transmission adjustment block 221 and the transmission guide rail 220, so that the stretching transmission frame 207 moves downward synchronously.

[0042] Furthermore, one end of the stretching transmission connecting rod 208 away from the stretching support frame 209 is fixedly connected to a stretching transmission gear 225, and one side of the stretching support plate 203 close to the stretching support frame 209 is fixedly connected to a double-sided rack 226 meshing with the stretching transmission gear 225. When the stretching transmission block 210 moves to the intersection of the horizontal section and the vertical section of the L-shaped guide groove 204, the double-sided rack 226 meshes with the stretching transmission gear 225. As the stretching transmission frame 207 continues to move upward, the two stretching transmission gears 225 rotate to drive the stretching transmission connecting rod 208 to rotate synchronously; a waxing transmission block is slidably arranged inside the L-shaped guide groove 204 The waxing transmission block is fixedly connected to the waxing support frame 205, and a reset spring 227 is fixedly connected between an inner wall of the L-shaped guide groove 204 and the waxing transmission block. One of the waxing blocks 206 is fixedly connected to the waxing support frame 205 through a first support plate, and the other waxing block 206 is fixedly connected to the second support plate through a side surface. An adjusting spring 228 is fixedly connected between the second support plate and the waxing support frame 205. The second support plate is pulled to compress the adjusting spring 228, so that the silk thread can be located between the two waxing blocks 206. Under the elastic recovery action of the adjusting spring 228, the two waxing blocks 206 are tightly attached to the silk thread.

[0043] The operation process of this embodiment is as follows: the silk thread is located between the two waxing blocks 206. When the silk thread moves a certain distance, the waxing blocks 206 wax the silk thread, and then control the pressing plate 201 and the limit pressing plate 202 to move downward. The specific operation process is as follows:

[0044] The electric push rod 214 is started to drive the lifting transmission block 215 to move downward. During this process, the driving connecting rod 216 rotates with the movement of the lifting transmission block 215. The lifting transmission block 215 pushes the corresponding first lifting connecting rod 212 and the second lifting connecting rod 213 to rotate synchronously, so that the angle between the two gradually increases, thereby causing the adjustment support frame 211 to move downward synchronously, driving the pressure clamp 201 and the limit pressure plate 202 to move downward.

[0045] As the pressing clamp 201 and the limiting pressure plate 202 move downward, when the pressing clamp 201 is in close contact with the side surface of the wire, the wire is clamped and fixed by the cooperation between the pressing clamp 201 and the pressing support plate 217. At the same time, the limiting pressure plate 202 is in close contact with the side surface of the wire, and the position of the wire is limited by the cooperation between the limiting pressure plate 202 and the limiting support plate 218. Then, by controlling the rotation of the first transmission wheel 223, the stretching adjustment connecting rod 224 is driven to rotate 180° clockwise synchronously (such as Figure 5 As shown), during this process, the transmission adjustment block 221 is driven to move synchronously by the stretching adjustment link 224. Under the sliding cooperation between the transmission adjustment block 221 and the transmission guide rail 220, the U-shaped transmission block moves upward, thereby driving the stretching transmission frame 207 to move upward, and the stretching transmission link 208 moves upward synchronously with the stretching transmission frame 207. Under the sliding cooperation between the stretching transmission block 210 and the corresponding L-shaped guide groove 204, the stretching transmission block 210 moves vertically upward along the vertical section of the L-shaped guide groove 204, and the stretching support frame 209 moves upward synchronously, driving the silk thread to move upward synchronously. Since one end of the silk thread is clamped and fixed by the pressure clamp 201 and the other end is located on the winding roller 402, the silk thread is continuously stretched. At the same time, while the silk thread is moving upward and being stretched, the silk thread moves upward along the waxing block 206 and continues to be waxed.

[0046] When the stretching transmission block 210 moves to the intersection of the horizontal section and the vertical section of the L-shaped guide groove 204, the double-sided rack 226 meshes with the stretching transmission gear 225. As the stretching transmission frame 207 continues to move upward, the meshing action of the double-sided rack 226 and the stretching transmission gear 225 makes the two stretching transmission connecting rods 208 rotate synchronously in opposite directions and move away from each other. Under the sliding cooperation between the stretching transmission block 210 and the L-shaped guide groove 204, the stretching transmission block 210 slides along the horizontal section of the L-shaped guide groove 204, driving the stretching support frame 209 to move horizontally and away from each other synchronously.
