When the yarn is straightened, it will be pressed on the surface of the lead ring. One end of the lead ring as a whole will be pressed. The lead ring is connected to the outer wall of the inner roller through the expansion block. When the lead ring is stressed, it will press the expansion block. The lead ring moves in the direction of the inner roller. The movement of the lead ring will drive the pressing column to move. The bottom end of the pressing column will contact and press the pressure plate. The surface of the pressure plate will be deformed under pressure. This will cause the resistance value of the pressure plate to change. The greater the pressure, the greater the change in resistance value.

[0016] Further, when the yarn contacts the auxiliary sizing roller, the yarn is limited by the convex rope block groove body to prevent the yarn from deviating, and when the yarn is on the convex rope block, the convex rope block is extruded, the movement of the convex rope block drives the magnetic column to move, the movement of the magnetic column cuts the coil of its own magnetic field, thereby generating an induced electromotive force, the size of the induced electromotive force is related to the movement distance of the convex rope block, the farther the movement distance of the convex rope block, the greater the induced electromotive force of the coil, and vice versa, the shorter the movement distance, the smaller the induced electromotive force, the size of the induced electromotive force is used to judge the pressure of the yarn, and a pressure buffering space of the yarn is also provided to prevent the yarn from being broken due to excessive pressure, and the convex rope block is provided with a plurality of convex rope blocks, which are mainly used to locally press the yarn, so that the surface gloss is observed by the visual detection unit to indirectly judge the sizing coverage.

[0017] The sizing roller assembly comprises a first yarn pressing roller and a second yarn pressing roller, the first yarn pressing roller is located at the top end of the first yarn guide roller, and the second yarn pressing roller is located at one side of the main sizing roller.

[0018] Further, the first yarn pressing roller and the second yarn pressing roller are both rotationally connected with the inner wall of the bottom sizing groove body. The first yarn pressing roller is used to change the contact position of the yarn with the second yarn guide roller and prevent the yarn from contacting the edge of the bottom sizing groove body; and the second yarn pressing roller is used to assist the main sizing roller. The connection route of the yarn is: first passing through the bottom end of the first yarn guide roller, then extending to the top end of the first yarn pressing roller, then extending to the bottom end of the second yarn guide roller, then extending to the top end of the third yarn guide roller, then extending to the bottom end of the dipping roller, then extending to the top end of the auxiliary sizing roller, and finally extending to the bottom end of the main sizing roller.

The pneumatic push rod is arranged at the bottom end of the sliding block, and the fixed end of the pneumatic push rod is fixedly connected with the bottom end of the mounting shell, and the output end of the pneumatic push rod is hingedly connected with the sliding block.

[0020] Further, the adjusting assembly is used to adjust the height and the inclination angle of the third yarn guide roller to realize the pressure adjustment of part of the yarn, prevent the yarn from being broken due to excessive pressure, or prevent the sizing material from being extruded due to insufficient pressure. The mounting shell is used as a mounting member and is located at both ends of the bottom sizing groove body. The two ends of the third yarn guide roller are rotationally connected with the sliding block. The pneumatic push rod is used as a power source to control the movement of the sliding block, and the movement of the sliding block drives the movement of the third yarn guide roller.

[0021] Compared with the prior art, the beneficial effects of the present application are: 1. In use, the elastic thread of this invention is squeezed by the yarn, which causes a change in distance. The yarn thickness is then determined based on the change in distance of the elastic thread. At the same time, the guide ring moves, which in turn moves the extrusion column. The extrusion column extrudes the pressure plate. The pressure on the yarn is determined based on the resistance value of the pressure plate. Then, by controlling the pneumatic push rod, the pressure on the yarn is adjusted according to the yarn thickness, preventing the yarn from having a low sizing rate due to unsuitable pressure.

[0022] 2. When the yarn enters the groove, the movement of the contact block reduces the size of the groove opening, thereby cooperating with the inner wall of the groove to restrict the yarn and prevent it from shifting. The elastic line also prevents yarns of the same size as the bottom groove from cooperating with each other and prevents the yarn from getting stuck in the bottom groove.

[0023] 3. In this invention, the yarn after the third yarn guide roller is restricted by the convex rope block groove to prevent yarn deviation. When the yarn is on the convex rope block, it will squeeze the convex rope block. The movement of the convex rope block under pressure will drive the magnetic column to move. The magnetic column's own magnetic field will cut the coil, thereby generating an induced electromotive force. The magnitude of the induced electromotive force determines the pressure of the subsequent yarn. In conjunction with the pressure plate, it realizes the overall control of the yarn pressure. At the same time, it makes the yarn locally compressed, so that the surface gloss can be observed through the visual inspection unit, and the sizing coverage can be indirectly judged.

[0026] 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.

[0027] Example: Figures 1-9 As shown, the present invention provides a sizing machine technical solution with intelligent pressure regulation function, including a bottom sizing tank body, a sizing roller assembly 1 on the bottom sizing tank body, an induced roller assembly 2 on one side of the sizing roller assembly 1, an induced yarn roller assembly 3 on the side of the bottom sizing tank body away from the induced roller assembly 2, a pressure assembly 4 inside the induced yarn roller assembly 3, the pressure assembly 4 being used to detect the pressure of the yarn on the roller body, an adjustment assembly 5 on the outer wall of the bottom sizing tank body, the adjustment assembly 5 being used to adjust the position of the roller body, and a yarn detection assembly 7 inside the pressure assembly 4, the yarn detection assembly 7 being used to detect the thickness of the yarn.

[0028] Specifically, during the process of yarn entering the sizing tank to absorb sizing and being pressed out of the sizing tank, the total amount of sizing liquid that the yarn can absorb is related to the impregnation method. The appropriate absorption amount of the yarn is a prerequisite for obtaining the sizing effect. During the sizing process, whether the sizing liquid can be reasonably distributed on the yarn is generally measured by the sizing effect of the main and pre-pressing sizing rollers. The bottom sizing tank body is an existing structure, mainly used to place the sizing liquid, and through the cooperation of multiple rollers, the yarn is straightened and its position is controlled so that the yarn can come into contact with the sizing liquid. The rollers are divided into the driving roller assembly 2, the yarn guiding roller assembly 3, and the pressing roller assembly 1. The pressure assembly 4 is used to detect the pressure on the rollers. The adjustment assembly 5 adjusts the height or tilt angle of the rollers according to the value obtained from the pressure assembly 4, thereby adjusting the pressure on the yarn. In use, since there are many types of yarn and each yarn has a different thickness, the pressure needs to be adjusted according to the thickness of the yarn.

[0029] like Figure 1 , Figure 2As shown, the yarn guide roller assembly 3 includes a first yarn guide roller 31, a second yarn guide roller 32 and a third yarn guide roller 33. The first yarn guide roller 31 is located on one side of the bottom groove body, and is rotatably connected to the inner wall of the bottom groove body. The second yarn guide roller 32 is located at the top end of the bottom groove body, and is provided with a pressure assembly 4. The third yarn guide roller 33 is located above the second yarn guide roller 32.

[0030] Specifically, the first yarn guide roller 31 is located at the bottom end of one side of the bottom groove body and is used as a roller body connected to the first yarn. The second yarn guide roller 32 is located at the top end of the bottom groove body close to one side of the first yarn guide roller 31. Both the first yarn guide roller 31 and the second yarn guide roller 32 are rotatably connected to the inner wall of the bottom groove body.

[0031] As shown in Figure 2 , Figure 4 , Figure 5 The pressure assembly 4 includes an inner roller 41, a lead ring 42 and an expansion block 43. The second yarn guide roller 32 has a cavity inside, and the inner roller 41 is located inside the cavity. The second yarn guide roller 32 has a ring groove on its surface, and the inner roller 41 is fixedly connected to the inner wall of the second yarn guide roller 32. The expansion block 43 is located on the outer wall of the inner roller 41, and the expansion block 43 is fixedly connected to the outer wall of the inner roller 41. The lead ring 42 is located at the top end of the expansion block 43, and the inner wall of the lead ring 42 is fixedly connected to the top end of the expansion block 43. The expansion block 43 is provided with a plurality of expansion blocks 43, which are arranged at equal intervals in a circle. A pressure plate 44 is provided between two expansion blocks 43, and the pressure plate 44 has an extrusion column 45 at its top end, which is fixedly connected to the bottom end of the lead ring 42.

[0032] Specifically, the ring groove cooperates with the lead ring 42 on the inner roller 41. When the yarn contacts the surface of the second yarn guide roller 32, the ring groove and the cavity are in communication with each other, and the yarn is limited by the ring groove. When the yarn is straightened, it will be extruded on the surface of the lead ring 42, and the lead ring 42 will be pressed on one end. The lead ring is connected to the outer wall of the inner roller 41 through the expansion block 43. When the lead ring 42 is stressed, it will extrude the expansion block 43, and the lead ring will move in the direction of the inner roller 41. The movement of the lead ring will drive the extrusion column 45 to move, and the bottom end of the extrusion column 45 will contact and extrude the pressure plate 44. The surface of the pressure plate 44 is deformed under pressure, which causes the resistance value of the pressure plate 44 to change. The greater the pressure, the greater the change in resistance value.

[0033] As shown in Figure 6As shown, the lead wire ring 42 is provided with a wire body detection assembly 7, the wire body detection assembly 7 includes an elastic wire 71, a point contact block 72, the lead wire ring 42 is provided with a groove 421, the groove 421 is provided with a bottom groove 422 at the bottom end, the opening of the bottom groove 422 is smaller than that of the groove 421, the point contact block 72 is located in the groove 421, and the point contact block 72 is provided with two, the point contact block 72 is slidably connected with the inner wall of the groove 421, and the elastic wire 71 is provided between the two point contact blocks 72, and the two ends of the elastic wire 71 are fixedly connected with the point contact blocks 72.

[0034] Specifically, the wire body detection assembly 7 is used for detecting the thickness of the yarn, the groove 421 is located on the surface of the lead wire ring 42, and the bottom end of the groove 421 is provided with the bottom groove 422. In use, the yarn will first contact the groove 421, then extrude the elastic wire 71, the elastic wire 71 will move to the central axis of the lead wire ring 42 under extrusion, the point contact block 72 will move relatively under the traction of the elastic wire 71, so that the distance between the two point contact blocks 72 changes. Because the moving distance of the elastic wire 71 in the groove 421 is related to the thickness of the yarn, the thicker the yarn is, the greater the distance between the point contact blocks 72 is, and the smaller the resistance value is. Conversely, the thinner the yarn is, the closer the distance is, and the greater the resistance value is. When the yarn extrudes the elastic wire 71, the size of the opening of the groove 421 will decrease when the point contact block 72 moves, thereby cooperating with the inner wall of the groove 421 to limit the yarn and prevent the yarn from deviating.

[0035] As shown in Figure 2 The lead roller assembly 2 includes a main sizing roller 21, a secondary sizing roller 22 and an immersion roller 23. The main sizing roller 21 is located on one side of the bottom sizing groove body top end away from the second lead roller 32. The secondary sizing roller 22 is located between the second lead roller 32 and the main sizing roller 21. The immersion roller 23 is located on one side of the secondary sizing roller 22 away from the main sizing roller 21. The outer wall of the bottom sizing groove body is provided with a rotating motor 24. The output end of the rotating motor 24 is provided with a driving wheel 25. One side of the main sizing roller 21 and the secondary sizing roller 22 is provided with a driven wheel 26. The driven wheel 26 is connected with the driving wheel 25 by a belt.

[0036] Specifically, the main sizing roller 21 and the secondary sizing roller 22 are used as power rollers to control the movement of the yarn. The immersion roller 23 is used to extrude the yarn to control the position of the yarn so that the yarn can contact the sizing material. The two ends of the immersion roller 23 are rotatably connected with the inner wall of the bottom sizing groove body. Then, the fixed end of the rotating motor 24 is fixed with the outer wall of the bottom sizing groove body as a power source to drive the driving wheel 25 to rotate. The driving wheel 25 drives one driven wheel 26 to rotate through the belt. The other driven wheel 26 is driven to rotate, thereby driving the main sizing roller 21 and the secondary sizing roller 22.

[0037] As shown in Figure 7 , Figure 9As shown, the vice sizing roller 22 is internally provided with a sizing detection assembly 8, which comprises a convex rope block 81, a coil 82 and a magnetic column 83. The vice sizing roller 22 is provided with a sliding groove, and the convex rope block 81 is in sliding connection with the sliding groove. The convex rope block 81 is provided with a plurality of convex rope blocks 81. The bottom end of the convex rope block 81 is provided with the magnetic column 83. The top end of the magnetic column 83 is fixedly connected with the bottom end of the convex rope block 81. The bottom end of the magnetic column 83 is in sliding connection with the bottom end of the sliding groove. The coil 82 is sleeved on the magnetic column 83. The vice sizing roller 22 is provided with a visual detection unit 84 above the vice sizing roller 22.

[0038] Specifically, when the yarn is in contact with the vice sizing roller 22, the yarn is limited by the groove of the convex rope block 81 to prevent the yarn from deviating. When the yarn is on the convex rope block 81, the convex rope block 81 is extruded. The movement of the convex rope block 81 under pressure will drive the magnetic column 83 to move. The movement of the magnetic column 83 will cut the coil 82, thereby generating an induced electromotive force. The size of the induced electromotive force is related to the movement distance of the convex rope block 81. The farther the movement distance of the convex rope block 81, the greater the induced electromotive force of the coil 82. Conversely, the shorter the movement distance, the smaller the induced electromotive force. The size of the induced electromotive force is used to judge the pressure of the yarn. The pressure buffer space of the yarn is also provided to prevent the yarn from being broken due to excessive pressure. The convex rope block 81 is provided with a plurality of convex rope blocks 81, which are mainly used to locally press the yarn, so that the surface gloss is observed by the visual detection unit 84 to indirectly judge the sizing coverage.

[0039] As shown in the Figure 2 , the sizing roller assembly 1 comprises a first presser roller 11 and a second presser roller 12. The first presser roller 11 is located at the top end of the first yarn guide roller 31. The second presser roller 12 is located on one side of the main sizing roller 21.

[0040] Specifically, the first presser roller 11 and the second presser roller 12 are both in rotational connection with the inner wall of the sizing groove body. The first presser roller 11 is used to change the contact position of the yarn with the second yarn guide roller 32 and prevent the yarn from contacting the edge of the sizing groove body. The second presser roller 12 is used to assist the main sizing roller 21. The connection route of the yarn is as follows: first, the yarn passes through the bottom end of the first yarn guide roller 31, then extends to the top end of the first presser roller 11, then extends to the bottom end of the second yarn guide roller 32, then extends to the top end of the third yarn guide roller 33, then extends to the bottom end of the dipping roller 23, then extends to the top end of the vice sizing roller 22, and finally extends to the bottom end of the main sizing roller 21.

[0041] As shown in the Figure 1 , Figure 3As shown, the adjusting assembly 5 comprises a mounting shell 51, a sliding block 52 and a pneumatic push rod 53. The mounting shell 51 is located on both sides of the third yarn guide roller 33 and is fixedly connected with the outer wall of the body of the bottom sizing groove. The sliding block 52 is located in the mounting shell 51 and is slidably connected with the inner wall of the mounting shell 51. The sliding block 52 is rotatably connected with one end of the third yarn guide roller 33. The pneumatic push rod 53 is arranged at the bottom end of the sliding block 52. The fixed end of the pneumatic push rod 53 is fixedly connected with the bottom end of the mounting shell 51. The output end of the pneumatic push rod 53 is hingedly connected with the sliding block 52.

[0042] Specifically, the adjusting assembly 5 is used to adjust the height and the inclination angle of the third yarn guide roller 33, so as to adjust the pressure on part of the yarn, prevent the yarn from being broken due to excessive pressure, and prevent the sizing material from being unable to be extruded due to insufficient pressure. The mounting shell 51 is used as a mounting member and is located at both ends of the body of the bottom sizing groove. The two ends of the third yarn guide roller 33 are rotatably connected with the sliding block 52. The pneumatic push rod 53 is used as a power source to control the movement of the sliding block 52. The movement of the sliding block 52 drives the movement of the third yarn guide roller 33.

[0043] Working principle: Before use, the yarn is first threaded through the bottom end of the first yarn guide roller 31, then extended to the top end of the first yarn pressing roller 11, then extended to the bottom end of the second yarn guide roller 32, then extended to the top end of the third yarn guide roller 33, then extended to the bottom end of the dipping roller 23, then extended to the top end of the auxiliary sizing roller 22, and finally extended to the bottom end of the main sizing roller 21. Then during the use of the device, the yarn will first contact the groove 421, then extrude the elastic wire 71, the elastic wire 71 will move towards the central axis of the lead wire ring 42 under extrusion, the point contact block 72 will move relatively under the traction of the elastic wire 71, and the distance will change. The thickness of the yarn is determined according to the resistance value. Then when the yarn is straightened, it will be extruded on the surface of the lead wire ring 42. One end of the lead wire ring 42 as a whole will be pressed and will also drive the movement of the lead wire ring 42. The lead wire ring 42 will drive the movement of the extrusion column 45, which will extrude the pressure plate 44. The yarn pressure is determined according to the changing resistance value. The height and the inclination angle of the third yarn guide roller 33 are adjusted according to the yarn pressure, so as to adjust the pressure on part of the yarn. Finally, the yarn will be limited by the groove of the convex rope block 81 to prevent the yarn from deviating. When the yarn is on the convex rope block 81, the convex rope block 81 will be extruded. The movement of the convex rope block 81 under pressure will drive the movement of the magnetic column 83. The movement of the magnetic column 83 will cut the coil 82, thereby generating an induced electromotive force. The size of the induced electromotive force determines the size of the subsequent yarn pressure. At the same time, the yarn is partially pressed, so that the surface gloss is observed through the visual detection unit 84, and the sizing coverage is indirectly determined.
