[0002] A spinning machine is a machine that processes short fibers into yarn. The preparation process usually includes steps such as opening, combing, and impurity removal. There are many types of spinning machines. The yarn guiding device of a spinning machine generally refers to the last mechanical device in the spinning machine. It usually guides the spun yarn to the winding device for subsequent processing, transportation, and use. Existing spinning yarn guiding devices generate friction between the yarn and the device during spinning. When the yarn tension is high, the friction between the yarn and the device can easily lead to yarn breakage, requiring machine downtime for maintenance. Summary of the Invention
[0003] The purpose of this invention is to provide an adaptive tension-adjustable spinning guide device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: an adaptive tension adjustment spinning guide device, comprising a base and a control box disposed on the base; the base is provided with a yarn guiding mechanism and an adjustment mechanism. The adjustment mechanism includes an electric slide rail mounted on a base. One side of the electric slide rail is electrically connected to a control box.

A second rack is provided on the side of the second moving block near the first moving block, and the second rack meshes with the gear. The gear is fixed on the electric slide rail. A second connecting post is connected to one side of the first moving block, and a first pressing plate is provided on one side of the second connecting post. A second pressing plate is provided at the bottom of the first pressing plate, and one end of the second pressing plate is fixed to the base. A first connecting rod is connected to one side of the first moving block, and a wax block is connected to the bottom of the first connecting rod.
[0005] Preferably, the yarn guiding mechanism includes a pay-off reel mounted on a base, a second insertion post mounted on the base, one end of the second insertion post penetrating the base and connected to a take-up roller, a first insertion post mounted on the base, one end of the first insertion post penetrating the base and connected to a winding roller, a winding block connected to the winding roller via a ball nut pair, a pressure sensor mounted on the base, and a winding bar mounted on the base.
[0006] Preferably, one end of the first moving block passes through an electric slide rail and is connected to two sets of second tension columns, and one end of the second moving block passes through a straightening block and is connected to a first tension column.
[0007] Preferably, a third connecting post is provided on one side of the first moving block, one end of the third connecting post is connected to a first fixing plate, one end of the first fixing plate is connected to a second connecting post, a second limiting plate is provided on one side of the second connecting post, a connecting cylinder is provided on the outside of the second limiting plate, a spring is provided inside the connecting cylinder, one end of the spring is fixedly connected to the second limiting plate, the other end of the spring is fixedly connected to the first extrusion plate, and a ceramic layer is provided at the bottom of the first extrusion plate.
[0008] Preferably, a limiting block is provided at both ends of the gear, and a first limiting disc is connected to both ends of the gear through the limiting block. A fixing block is provided at one end of the limiting block, and the fixing block is fixedly connected to the electric slide rail.
[0009] Preferably, a fixing post is fixed on the base, one end of which is connected to a second extrusion sheet, and a ceramic layer is also provided on the second extrusion sheet.

[0011] Compared with the prior art, the beneficial effects of the present invention are: When the yarn tension is high, this invention applies wax to the spinning process by rubbing the yarn against a wax block. This reduces the friction between the yarn and the device during spinning and stretching, thus preventing damage to the yarn due to friction with the device when the yarn tension is too high, which could lead to yarn breakage during operation and affect the operation of the device.
[0012] This invention compresses yarn with low tension by having the first extrusion plate move downwards and contact the second extrusion plate, thus preventing the yarn from knotting during winding. At the same time, after the first extrusion plate and the second extrusion plate compress each other, the second connecting post moves downwards and drives the second limiting disc to compress the spring, thereby preventing the first extrusion plate from directly contacting the second extrusion plate when it moves, which would cause excessive compression of the yarn on the second extrusion plate and thus damage the yarn.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0016] Please see Figures 1 to 8 The present invention provides a spinning guide device with adaptive tension adjustment, including a base 1 and a control box 21 disposed on the base 1. The base 1 is provided with a yarn guiding mechanism 2 and an adjustment mechanism 3. The adjustment mechanism 3 includes an electric slide rail 37 mounted on the base 1. One side of the electric slide rail 37 is electrically connected to the control box 21. Inside the electric slide rail 37, there are a first moving block 31 and a second moving block 39. A first rack is provided on the side of the first moving block 31 near the second moving block 39. A gear 32 is meshed on the side of the first moving block 31. A second rack is provided on the side of the second moving block 39 near the first moving block 31. The second rack meshes with the gear 32. The gear 32 is fixed on the electric slide rail 37. A second connecting post 313 is connected to one side of the first moving block 31. A first pressing plate 317 is provided on one side of the second connecting post 313. A second pressing plate 319 is provided at the bottom of the first pressing plate 317. One end of the second pressing plate 319 is fixed to the base 1. A first connecting rod 310 is connected to one side of the first moving block 31. A wax block 312 is connected to the bottom of the first connecting rod 310.
[0017] In use, the yarn is placed on the pay-off reel 22. The yarn enters the winding bar 29 through the pressure sensor 28. The winding bar 29 restricts the yarn. The yarn in the winding bar 29 passes through the lower ends of the two sets of second tension columns 38 and the upper ends of the first tension column 33, thereby stretching and restricting the yarn. At the same time, the yarn enters the winding block 27. The motor on one side of the winding roller 26 drives the first insertion column 23 to rotate. The rotation of the first insertion column 23 drives the winding roller 26 to rotate. The rotation of the winding roller 26 drives the winding block 27 to reciprocate on the winding roller 26 through the ball nut pair connection. At the same time, the motor drives the second insertion column 24 to rotate, which drives the take-up roller 25 to rotate and wind up the yarn. The reciprocating movement of the winding block 27 makes the yarn winding more uniform.
[0018] Simultaneously, the tension of the wound yarn is detected by the pressure sensor 28. When excessive tension is detected, the control box 21 controls the first moving block 31 inside the electric slide rail 37 to move upward. The upward movement of the first moving block 31 drives the second tension column 38 to move upward. At the same time, the upward movement of the first moving block 31 causes the first rack on the first moving block 31 to mesh with the gear 32, which in turn drives the gear 32 to rotate. The rotation of the gear 32, through meshing with the second rack on the second moving block 39, causes the second moving block 39 to move in the opposite direction to the first moving block 31. This brings the second tension column 38 closer to the first tension column 33, thereby reducing the tension. When the yarn tension is detected to be too low, the control box 21 controls the first moving block 31 inside the electric slide rail 37 to move downward. The downward movement of the first moving block 31 drives the second tension column 38 to move downward. At the same time, the downward movement of the first moving block 31 causes the first rack on the first moving block 31 to mesh with the gear 32, which in turn drives the gear 32 to rotate. The rotation of the gear 32 causes the second moving block 39 to move in the opposite direction to the first moving block 31, so that the second tension column 38 and the first tension column 33 move away from each other, thereby increasing the yarn tension and avoiding the impact of insufficient tension.
[0019] Simultaneously, when the pressure sensor 28 detects that the yarn tension is too high, the control box 21 controls the first moving block 31 to move upward inside the electric slide rail 37. The upward movement of the first moving block 31 drives the fourth connecting column 323 to move upward, which in turn drives the second fixing plate 322 to move upward. The upward movement of the second fixing plate 322 drives the first connecting rod 310, which in turn drives the placement box 311 to move. The movement of the placement box 311 causes the wax block 312 to come into contact with the yarn. Thus, when the spinning tension is high, the wax is applied to the yarn through friction between the yarn and the wax block 312, reducing the friction between the yarn and the device during spinning stretching. This prevents damage to the yarn due to friction with the device when the yarn tension is too high, which could lead to yarn breakage during operation and affect the operation of the device.
[0020] Simultaneously, when the pressure sensor 28 detects low yarn tension, the control box 21 controls the first moving block 31 to move downward inside the electric slide rail 37. The downward movement of the first moving block 31 causes the third connecting column 321 to move downward, which in turn causes the first fixing plate 320 to move downward. The downward movement of the first fixing plate 320 causes the second connecting column 313 to move downward, which in turn causes the second limiting plate 316 to move downward. The downward movement of the second limiting plate 316 causes the spring 315 to move downward, which in turn causes the first... The extrusion plate 317 moves downward, and the first extrusion plate 317 moves downward to contact and squeeze the second extrusion plate 319. This squeezes the yarn with low tension, preventing the yarn from knotting during winding. At the same time, after the first extrusion plate 317 and the second extrusion plate 319 squeeze each other, the second connecting post 313 moves downward, which drives the second limiting plate 316 to squeeze the spring 315. This prevents the first extrusion plate 317 from directly contacting the second extrusion plate 319 when it moves, thus avoiding excessive squeezing of the yarn on the second extrusion plate 319 and damage to the yarn.
[0021] In an optional embodiment, the yarn guiding mechanism 2 includes a yarn feeding reel 22 disposed on a base 1. A second insertion post 24 is also disposed on the base 1. One end of the second insertion post 24 passes through the base 1 and is connected to a take-up roller 25. A first insertion post 23 is also disposed on the base 1. One end of the first insertion post 23 passes through the base 1 and is connected to a winding roller 26. A winding block 27 is connected to the winding roller 26 through a ball nut pair. A pressure sensor 28 is also disposed on the base 1. A winding bar 29 is also disposed on the base 1.
[0022] It should be noted that during use, the yarn is placed on the pay-off reel 22. The yarn enters the winding bar 29 through the pressure sensor 28. The winding bar 29 restricts the yarn. The yarn in the winding bar 29 passes through the lower ends of the two sets of second tension columns 38 and the upper ends of the first tension column 33, thereby stretching and restricting the yarn. At the same time, the yarn enters the winding block 27. The motor on one side of the winding roller 26 drives the first insertion column 23 to rotate. The rotation of the first insertion column 23 drives the winding roller 26 to rotate. The rotation of the winding roller 26 drives the winding block 27 to reciprocate on the winding roller 26 through the ball nut pair connection. At the same time, the motor drives the second insertion column 24 to rotate, which drives the take-up roller 25 to rotate and wind up the yarn.
[0023] In an optional embodiment, one end of the first moving block 31 passes through the electric slide rail 37 and is connected to two sets of second tension columns 38, and one end of the second moving block 39 passes through the straightening block 27 and is connected to the first tension column 33.
[0024] It should be noted that the tension of the wound yarn is detected by the pressure sensor 28, and the tension of the yarn is controlled by the control box 21 by the first moving block 31 sliding inside the electric slide rail 37.
[0025] In an optional embodiment, a third connecting post 321 is provided on one side of the first moving block 31. One end of the third connecting post 321 is connected to a first fixing plate 320. One end of the first fixing plate 320 is connected to a second connecting post 313. A second limiting plate 316 is provided on one side of the second connecting post 313. A connecting cylinder 314 is provided on the outside of the second limiting plate 316. A spring 315 is provided inside the connecting cylinder 314. One end of the spring 315 is fixedly connected to the second limiting plate 316. The other end of the spring 315 is fixedly connected to a first extrusion plate 317. A ceramic layer is provided at the bottom of the first extrusion plate 317.
[0026] It should be noted that when the pressure sensor 28 detects that the yarn tension is low, the control box 21 controls the first moving block 31 to move down inside the electric slide rail 37. The movement of the first moving block 31 causes the third connecting column 321 to move down, which in turn causes the first fixing plate 320 to move down. The movement of the first fixing plate 320 causes the second connecting column 313 to move down, which in turn causes the second limiting plate 316 to move down. The movement of the second limiting plate 316 causes the spring 315 to move down, which in turn causes the first squeezing plate 317 to move down. The first squeezing plate 317 then comes into contact with the second squeezing plate 319 and squeezes the yarn with low tension.
[0027] In an optional embodiment, a limiting block 34 is provided at both ends of the gear 32, and a first limiting disk 36 is connected to both ends of the gear 32 through the limiting block 34. A fixing block 35 is provided at one end of the limiting block 34, and the fixing block 35 is fixedly connected to the electric slide rail 37.
[0028] It should be noted that the first limiting plate 36 restricts the gear 32 to prevent the gear 32 from deviating from the predetermined track when rotating. At the same time, the fixing block 35 and the limiting block 34 fix the gear 32, thereby restricting the gear 32 to the electric slide rail 37.
[0029] In an optional embodiment, a fixing post 318 is fixed on the base 1, one end of the fixing post 318 is connected to the second extrusion sheet 319, and the second extrusion sheet 319 is also provided with a ceramic layer.
[0030] It should be noted that when the first extrusion plate 317 and the second extrusion plate 319 are simultaneously extruded, the second connecting post 313 moves down and drives the second limiting plate 316 to compress the spring 315, thereby preventing the first extrusion plate 317 from directly contacting the second extrusion plate 319 when it moves, which would cause excessive compression of the yarn on the second extrusion plate 319 and thus damage the yarn.
[0031] In an optional embodiment, a fourth connecting post 323 is connected to one side of the first moving block 31, a second fixing plate 322 is fixed to one side of the fourth connecting post 323, a first connecting rod 310 is fixed to one side of the second fixing plate 322, one end of the first connecting rod 310 is connected to a placement box 311, and the wax block 312 is placed inside the placement box 311.
[0032] It should be noted that when the pressure sensor 28 detects that the yarn tension is high, the control box 21 controls the first moving block 31 to move upward inside the electric slide rail 37. The upward movement of the first moving block 31 drives the fourth connecting column 323 to move upward, which in turn drives the second fixing plate 322 to move upward. The upward movement of the second fixing plate 322 drives the first connecting rod 310, which in turn drives the placement box 311 to move. The movement of the placement box 311 causes the wax block 312 to come into contact with the yarn, so that when the spinning tension is high, the yarn rubs against the wax block 312.
[0033] Working principle: In use, the yarn is placed on the pay-off reel 22. The yarn enters the winding bar 29 through the pressure sensor 28. The winding bar 29 restricts the yarn. The yarn in the winding bar 29 passes through the lower ends of the two sets of second tension columns 38 and the upper ends of the first tension column 33, thereby stretching and restricting the yarn. At the same time, the yarn enters the winding block 27. The motor on one side of the winding roller 26 drives the first insertion column 23 to rotate. The rotation of the first insertion column 23 drives the winding roller 26 to rotate. The rotation of the winding roller 26 drives the winding block 27 to reciprocate on the winding roller 26 through the ball nut pair connection. At the same time, the motor drives the second insertion column 24 to rotate, which drives the take-up roller 25 to rotate and wind up the yarn. The reciprocating movement of the winding block 27 makes the yarn winding more even.
[0034] Simultaneously, the tension of the wound yarn is detected by the pressure sensor 28. When excessive tension is detected, the control box 21 controls the first moving block 31 inside the electric slide rail 37 to move upward. The upward movement of the first moving block 31 drives the second tension column 38 to move upward. At the same time, the upward movement of the first moving block 31 causes the first rack on the first moving block 31 to mesh with the gear 32, which in turn drives the gear 32 to rotate. The rotation of the gear 32 then causes the second moving block 39 to move in the opposite direction to the first moving block 31 through meshing with the second rack on the second moving block 39. This causes the second tension column 38 to move upward. When the tension on the yarn is detected to be too low, the first moving block 31 inside the electric slide rail 37 is moved down by the control box 21. The movement of the first moving block 31 causes the second tension column 38 to move down. At the same time, the movement of the first moving block 31 causes the first rack on the first moving block 31 to mesh with the gear 32, which in turn causes the gear 32 to rotate. The rotation of the gear 32 causes the second moving block 39 to move in the opposite direction to the first moving block 31 by meshing with the second rack on the second moving block 39, so that the second tension column 38 and the first tension column 33 move away from each other.
[0035] Simultaneously, when the pressure sensor 28 detects that the yarn tension is high, the control box 21 controls the first moving block 31 to move upward inside the electric slide rail 37. The upward movement of the first moving block 31 drives the fourth connecting column 323 to move upward, which in turn drives the second fixing plate 322 to move upward. The upward movement of the second fixing plate 322 drives the first connecting rod 310, which in turn drives the placement box 311 to move. The movement of the placement box 311 causes the wax block 312 to come into contact with the yarn. Thus, when the spinning tension is high, the wax is applied to the yarn by friction between the yarn and the wax block 312.
[0036] Simultaneously, when the pressure sensor 28 detects that the yarn tension is low, the control box 21 controls the first moving block 31 to move downward inside the electric slide rail 37. The downward movement of the first moving block 31 causes the third connecting column 321 to move downward, which in turn causes the first fixing plate 320 to move downward. The downward movement of the first fixing plate 320 causes the second connecting column 313 to move downward, which in turn causes the second limiting disc 316 to move downward. The downward movement of the second limiting disc 316 causes the spring 315 to move downward, which in turn causes the first squeezing plate 317 to move downward. The downward movement of the first squeezing plate 317 contacts and squeezes the second squeezing plate 319, squeezing the yarn with low tension to prevent the yarn from knotting during winding. At the same time, after the first squeezing plate 317 and the second squeezing plate 319 squeeze each other, the downward movement of the second connecting column 313 causes the second limiting disc 316 to squeeze the spring 315.
