Description

Technical Field

[0001] This invention relates to the field of yarn winding equipment, specifically a glass fiber composite yarn winding mechanism. Background Technology

[0002] To facilitate subsequent transportation, storage, unwinding, and use in different composite material molding processes, continuously produced yarns must be neatly and tightly wound into yarn bobbins of certain specifications. The winding of glass fiber composite yarns is an indispensable part of the production process, and its quality directly affects the physical properties of the yarns and the smoothness of subsequent processing.

[0003] Currently, a typical winding mechanism mainly consists of a rotating winding shaft, a reciprocating yarn guide, and a tensioning wheel to tension the yarn. The yarn is drawn from the upstream process, passes through the tensioning wheel to obtain a set tension, and then passes through the reciprocating yarn guide. Finally, it is guided to the surface of the rotating drum. With the rotation of the drum and the reciprocating movement of the yarn guide, the yarn is evenly wound onto the drum layer by layer and circle by circle until the predetermined winding amount is reached.

[0004] However, when the yarn guide moves back and forth, it will repeatedly pull the yarn. Traditional mechanical tensioning rollers cannot compensate for this rapid pulling in time due to inertia and frictional resistance. This results in inconsistent actual winding tension of the yarn at different positions in the package, which ultimately manifests as uneven tightness of the yarn layers inside the package, affecting the smoothness of unwinding.

[0005] In addition, existing technology uses a hydraulic cylinder to drive the yarn guide to reciprocate, so that the yarn guide winds the yarn onto the drum. However, since the extension section of the hydraulic cylinder slows down when it moves to the reversing point at both ends of the drum, the yarn guide will stay at the reversing point at both ends of the drum for a longer time than it stays in the middle of the drum. This causes the yarn to have a shoulder shape on the drum, which further affects the smoothness of unwinding. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a glass fiber composite yarn winding mechanism, including a base and a hydraulic cylinder fixedly installed on the base. The telescopic section of the hydraulic cylinder and the base are provided with a yarn guiding unit for guiding the yarn back and forth on the yarn roll. The base is provided with a shaping unit for shaping the yarn roll.

[0007] The yarn guiding unit includes a limiting frame fixedly installed at the front end of the telescopic section of the hydraulic cylinder. A guide frame is hinged to the right side of the limiting frame. A movable plate is slidably arranged on the front side of the base. A pull plate is hinged together between the movable plate and the limiting frame. A tensioning component is provided on the movable plate.

[0008] The shaping unit includes a sliding plate that slides left and right on the front side of the base. A helical spring is provided between the sliding plate and the base. A T-shaped roller frame is fixedly installed on the right side of the sliding plate. Two shaping rollers are rotatably arranged in a symmetrical manner on the T-shaped roller frame.

[0009] The telescopic section of the reciprocating telescopic hydraulic cylinder drives the limit frame to move back and forth, which in turn causes the limit frame to pull the moving plate to move left and right via the pull plate, thereby preventing the yarn from being pulled when the limit frame moves.

[0010] Preferably, a spring telescopic rod is hinged between the upper center of the guide frame and the upper left end of the limiting frame, and two rotating rollers are symmetrically arranged on the right side of the limiting frame, with the axis of the rotating rollers arranged vertically.

[0011] Preferably, the limiting frame is provided with a movable frame that slides up and down, and limiting rollers are rotatably provided on the right side of the movable frame and inside the limiting frame. The axis of the limiting rollers is arranged horizontally, and an adjusting screw is rotatably provided on the limiting frame. The adjusting screw is threadedly connected to the movable frame.

[0012] Preferably, a U-shaped frame is slidably provided on the right side of the guide frame, and a squeezing roller is rotatably provided on the lower side of the U-shaped frame and the right side of the guide frame. A locking screw that is threadedly connected to the horizontal section of the U-shaped frame is rotatably provided on the upper side of the guide frame.

[0013] Preferably, the tensioning assembly includes a tensioning wheel frame that is slidably mounted on the front side of the movable plate via a support plate, a tensioning wheel that is rotatably mounted on the lower side of the tensioning wheel frame, an L-shaped plate that is slidably mounted on the front side of the movable plate, and a push spring that is mounted between the horizontal section of the L-shaped plate and the tensioning wheel frame.

[0014] Preferably, a linkage column is fixedly installed on the rear side of the vertical section of the L-shaped plate, and an inclined groove with the left side lower than the right side is opened on the pedestal, and the linkage column is slidably connected inside the inclined groove.

[0015] Preferably, the shaping roller has a conical structure with a larger diameter at the position away from the transverse section of the T-shaped roller frame and a smaller diameter at the position closer to the transverse section of the T-shaped roller frame, and a rubber sleeve is provided on the outer side of the shaping roller.

[0016] Preferably, the inner side of the shaping roller is provided with a linkage plate that is slidably connected in the front and rear along its circumference at equal intervals, and grooved rollers are fixedly installed at both ends of the longitudinal section of the T-shaped roller frame. A protruding column that is slidably connected inside the groove of the grooved roller is fixedly installed on the side of the linkage plate near the axis of the shaping roller.

[0017] Preferably, a scraper is slidably provided on the side of the linkage plate away from the axis of the shaping roller along the radial direction of the shaping roller, and a return spring is provided between the scraper and the linkage plate.

[0018] Preferably, the scraper is comb-shaped on the side away from the axis of the shaping roller, and a counterweight is fixedly installed on the side of the scraper close to the axis of the shaping roller.

[0019] The beneficial effects of the present invention are as follows: First, the present invention uses a hydraulic cylinder to drive the limiting frame and the guide frame to move back and forth to guide the yarn. At the same time, through the design of the pull plate linking the moving plate to move left and right, the relative distance between the tensioning component and the limiting frame is kept constant, which effectively reduces the repeated pulling effect on the yarn during the reciprocating motion of the limiting frame. In addition, the hinged guide frame can adaptively deflect when the yarn is under force, further buffering the pulling impact.

[0020] Second, when the movable plate linkage tensioning component moves, the L-shaped plate slides up and down along the inclined groove trajectory through the sliding cooperation between the L-shaped plate and the inclined groove on the base. When the yarn is stretched, the tensioning wheel automatically reduces the tensioning pressure on the yarn, further alleviating the instantaneous impact on the yarn when it changes direction, and effectively ensuring more stable winding tension.

[0021] Third, the present invention uses a tapered shaping roller that continuously squeezes the yarn toward the center of the roll when it rolls and contacts the yarn roll, directly eliminating the phenomenon of shoulders at both ends of the yarn roll. At the same time, the sliding cooperation between the protruding column and the grooved roller drives the scraper to squeeze the rubber sleeve, so that the surface of the rubber sleeve pushes the yarn in a peristaltic manner, further shaping the yarn roll.

[0022] Fourth, the present invention adopts a design of setting a counterweight block inside the scraper. When the outer diameter of the yarn roll increases, causing the speed of the shaping roller to increase, the counterweight block pushes the scraper to move radially outward under the centrifugal effect, increasing its radial squeezing force on the yarn. By dynamically increasing the force to adjust the shaping intensity, the shaping effect is further guaranteed. Attached Figure Description

[0031] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0032] See Figure 1 A glass fiber composite yarn winding mechanism includes a base 1 and a hydraulic cylinder 2 fixedly installed on the base 1. The telescopic section of the hydraulic cylinder 2 and the base 1 are provided with a yarn guiding unit 3 for guiding the yarn back and forth on the yarn roll. The base 1 is provided with a shaping unit 4 for shaping the yarn roll.

[0033] It should be noted that the right side of the front of the base 1 is equipped with a rotating shaft controlled by a synchronous motor.

[0034] When the yarn needs to be wound up, the operator manually places the drum on the outside of the rotating shaft and locks it on the rotating shaft. Then, the operator manually pulls the yarn out from the pre-leading structure to the yarn guide unit 3. Then, the yarn is connected to the drum from the yarn guide unit 3. Then, the shaping unit 4 automatically abuts against the outside of the yarn on the drum and starts the synchronous motor to drive the drum to start rotating clockwise. At the same time, the extension section of the reciprocating hydraulic cylinder 2 extends back and forth.

[0035] The continuously rotating drum pulls the yarn around its outer surface. The telescopic section of the hydraulic cylinder 2, which reciprocates back and forth, drives the yarn guide unit 3 to move continuously, so that the yarn is evenly wound around the drum layer by layer and circle by circle. At the same time, the shaping unit 4 squeezes the yarn at both ends of the drum towards the middle of the drum to shape the yarn roll and ensure smooth unwinding.

[0036] See Figure 1 and Figure 2 The yarn guiding unit 3 includes a limiting frame 31 fixedly installed at the front end of the telescopic section of the hydraulic cylinder 2. A guide frame 32 is hinged to the right side of the limiting frame 31. A movable plate 33 is slidably arranged on the front side of the base 1. A pull plate 34 is hinged together between the movable plate 33 and the limiting frame 31. A tensioning component 35 is provided on the movable plate 33.

[0037] See Figure 1 , Figure 2 and Figure 4 The tensioning assembly 35 includes a tensioning wheel frame 352 that is slidably mounted on the front side of the movable plate 33 via a support plate 351. A tensioning wheel 353 is rotatably mounted on the lower side of the tensioning wheel frame 352. An L-shaped plate 354 is slidably mounted on the front side of the movable plate 33. A push spring is provided between the horizontal section of the L-shaped plate 354 and the tensioning wheel frame 352.

[0038] It should be noted that, as Figure 1 As shown, reversing rollers 36 are rotatably installed on the upper left side of the platform 1 and the right side of the movable plate 33.

[0039] When the yarn needs to be wound onto the drum, the operator holds the yarn and pulls it out from the lead-in structure from right to left. Then, the pulled-out yarn is wound from top to bottom around the outside of the left reversing roller 36. Next, the yarn is wound from bottom to top around the lower part of the tensioning wheel 353. Then, the yarn is wound from top to bottom around the outside of the right reversing roller 36. The yarn is then sequentially introduced into the interior of the limiting frame 31 and the guide frame 32. The yarn that passes through the right end of the guide frame 32 is then connected to the outer surface of the drum. This allows the tensioning wheel 353 to tension the yarn between the two reversing rollers 36 by its own weight and the elastic force of the push spring pushing the tensioning wheel frame 352 and the tensioning wheel 353 downward.

[0040] See Figure 1 , Figure 2 and Figure 3 The limiting frame 31 is provided with a movable frame 311 that slides up and down. The right side of the movable frame 311 and the inside of the limiting frame 31 are both provided with limiting rollers 312 that rotate. The axis of the limiting rollers 312 is arranged horizontally. An adjusting screw 313 is rotatably provided on the limiting frame 31 and is threadedly connected to the movable frame 311.

[0041] Continue reading Figure 1 , Figure 2 and Figure 3 A U-shaped frame 323 is slidably mounted on the right side of the guide frame 32. A squeezing roller 324 is rotatably mounted on the lower side of the U-shaped frame 323 and the right side of the guide frame 32. A locking screw 325 is rotatably mounted on the upper side of the guide frame 32 and threadedly connected to the horizontal section of the U-shaped frame 323.

[0042] Continue reading Figure 1 , Figure 2 and Figure 3 A spring telescopic rod 321 is hinged between the upper center of the guide frame 32 and the upper left end of the limit frame 31. Two rotating rollers 322 are symmetrically arranged on the right side of the limit frame 31, and the axis of the rotating rollers 322 is vertically arranged.

[0043] When the yarn passes through the interior of the limiting frame 31 and the guide frame 32, the yarn is positioned between the two limiting rollers 312, the two rotating rollers 322, and the two squeezing rollers 324 from left to right. Then, the operator manually turns the adjusting screw 313 and the locking screw 325. The adjusting screw 313 drives the moving frame 311 to move downward, so that the upper limiting roller 312 and the lower limiting roller 312 cooperate to clamp the yarn. The locking screw 325 drives the U-shaped frame 323 to move downward, so that the upper squeezing roller 324 and the lower squeezing roller 324 cooperate to clamp the yarn.

[0044] By squeezing and limiting the yarn, the yarn moves in a fixed position inside the limiting frame 31 and the guide frame 32, preventing the yarn from contacting and rubbing against the edge of the limiting frame 31 when the limiting frame 31 moves back and forth, thus preventing wear on the yarn.

[0045] When the drum starts to rotate and wind the yarn, the telescopic section of the reciprocating hydraulic cylinder 2 drives the limit frame 31 to move back and forth. The limit frame 31 drives the guide frame 32 to move back and forth synchronously, so that the yarn wound on the drum pulls on the guide frame 32. The pulling force of the yarn causes the guide frame 32 to deflect along its hinge point, while compressing the spring telescopic rod 321. Thus, by adaptively adjusting the deflection angle of the guide frame 32 according to the pulling of the yarn, the pulling impact force of the yarn is buffered, effectively preventing damage to the yarn and improving the uniformity of the tightness of the yarn layers inside the package.

[0046] Simultaneously, when the limiting frame 31 moves forward or backward away from the tensioning wheel 353, the limiting frame 31 pulls the moving plate 33 to the right through the pull plate 34. The moving plate 33 drives the tensioning wheel 353 to move to the right synchronously through the tensioning wheel frame 352. Conversely, when the limiting frame 31 moves forward or backward towards the tensioning wheel 353, the tensioning wheel 353 moves to the left synchronously. This effectively controls the horizontal distance between the tensioning wheel 353 and the limiting frame 31, thereby effectively preventing the limiting frame 31 from causing a large pulling impact on the yarn during its reciprocating movement.

[0047] See Figure 1 , Figure 2 and Figure 4 A linkage column 355 is fixedly installed on the rear side of the vertical section of the L-shaped plate 354. An inclined groove with the left side lower than the right side is opened on the base 1, and the linkage column 355 is slidably connected inside the inclined groove.

[0048] When the moving plate 33 moves to the right, it drives the L-shaped plate 354 to move to the right simultaneously. This causes the L-shaped plate 354 to drive the linkage column 355 to move upward along the inclined groove, thereby causing the L-shaped plate 354 to move upward synchronously. This reduces the compression of the push spring and reduces the tensioning force of the tensioning wheel 353 on the yarn. This further alleviates the instantaneous impact on the yarn during reversal and effectively ensures more stable winding tension.

[0049] See Figure 1 , Figure 5 and Figure 6 The shaping unit 4 includes a sliding plate 41 that is slidably disposed on the front side of the base 1. A helical spring is disposed between the sliding plate 41 and the base 1. A T-shaped roller frame 42 is fixedly installed on the right side of the sliding plate 41. Two shaping rollers 43 are rotatably disposed on the T-shaped roller frame 42 and arranged symmetrically in front and behind.

[0050] See Figure 5 and Figure 6 The shaping roller 43 has a conical structure with a large diameter in the lateral section away from the T-shaped roller frame 42 and a small diameter in the lateral section near the T-shaped roller frame 42. A rubber sleeve 436 is fitted on the outer side of the shaping roller 43.

[0051] In the initial state, the helical spring pushes the sliding plate 41 to the right through its own elastic force, so that the sliding plate 41 drives the rubber sleeves 436 on the two shaping rollers 43 to abut against the outside of the yarn on the drum through the T-shaped roller frame 42. When the drum rotates, the friction between the outer yarn roll and the rubber sleeve 436 drives the shaping rollers 43 to rotate synchronously. Due to the conical structure of the shaping rollers 43, the squeezing force of the shaping rollers 43 on the ends of the yarn roll is greater than that on the middle, so that the shaping rollers 43 squeeze the middle of the yarn located at the front and rear ends, effectively solving the problem of the convex shoulder of the yarn roll.

[0052] As the drum rotates, the outer diameter of the yarn roll on the drum gradually increases, and the linear speed of the yarn roll gradually increases, which gradually increases the pulling speed of the yarn roll on the yarn. This results in a gradual increase in the force of the yarn winding on the yarn roll. The yarn roll with its gradually increasing outer diameter continues to push the shaping roller 43 to the left, while gradually compressing the helical spring. This gradually increases the pushing force of the helical spring, thereby gradually increasing the force of the yarn winding on the yarn roll and automatically increasing the resistance of the shaping roller 43 to the yarn roll. This adaptively adjusts the shaping intensity of the yarn roll, effectively ensuring the shaping effect.

[0053] Continue reading Figure 5 and Figure 6The inner side of the shaping roller 43 is provided with a linkage plate 431 that is slidably connected in the front and rear along its circumference. The longitudinal section of the T-shaped roller frame 42 is fixedly installed with grooved rollers 432 at both ends. The grooved rollers 432 are located inside the shaping roller 43 and are coaxially arranged. The linkage plate 431 is fixedly installed with a protruding column 433 that is slidably connected inside the groove of the grooved roller 432 on the side close to the axis of the shaping roller 43.

[0054] Continue reading Figure 5 and Figure 6 A scraper 434 is slidably provided on the side of the linkage plate 431 away from the axis of the shaping roller 43 along the radial direction of the shaping roller 43, and a return spring is provided between the scraper 434 and the linkage plate 431.

[0055] Continue reading Figure 5 and Figure 6 The scraper 434 is comb-shaped on the side away from the axis of the shaping roller 43, and a counterweight 435 is fixedly installed on the side of the scraper 434 close to the axis of the shaping roller 43.

[0056] It should be noted that the groove on the groove roller 432 has a closed-loop structure consisting of two parts. The right part of the groove on the groove roller 432 has a spiral structure that gradually extends towards the T-shaped roller frame 42 along the rotation direction of the shaping roller 43, while the left part of the groove has a spiral structure that gradually extends away from the T-shaped roller frame 42 along the rotation direction of the shaping roller 43.

[0057] In the initial state, the return spring pushes the scraper 434 outward with its own elastic force, causing the comb structure of the scraper 434 to push against the rubber sleeve 436 outward. This causes the outer surface of the rubber sleeve 436 to form a wave structure due to the push of the comb structure of the scraper 434. When the rubber sleeve 436 abuts against the yarn roll, the reaction force of the yarn roll on the rubber sleeve 436 pushes the scraper 434 inward.

[0058] When the shaping roller 43 starts to rotate, the shaping roller 43 drives the linkage plate 431 on it to rotate around the groove roller 432, so that the protrusion 433 on the linkage plate 431 slides along the groove on the groove roller 432. At the same time, the linkage plate 431 drives the scraper 434 to rotate around the groove roller 432. When the scraper 434 rotates to the right side of the groove roller 432, the scraper 434 pushes the rubber sleeve 436 to contact the yarn roll. At the same time, the linkage plate 431 corresponding to the scraper 434 moves along the groove on the groove roller 432 towards the T-shaped roller frame 42.

[0059] This causes the scraper 434, which is close to the yarn roll, to move towards the center of the yarn roll under the push of the linkage plate 431. The moving scraper 434 pushes the wavy structure protrusion of the rubber sleeve 436 to move continuously towards the center of the yarn roll. Through this peristaltic pushing of the yarn roll by the outer side of the rubber sleeve 436, the yarn roll is further shaped to prevent the occurrence of shoulder protrusion.

[0060] As the outer diameter of the yarn roll increases, the yarn roll drives the forming roller 43 to rotate faster. The forming roller 43 drives the scraper 434 and the counterweight 435 to rotate faster in sync. Under the centrifugal effect, the counterweight 435 pushes the scraper 434 to move radially outward along the forming roller 43, increasing the radial squeezing force of the scraper 434 on the yarn. By dynamically increasing the force to adjust the forming intensity, the forming effect is further guaranteed.

[0061] See Figures 1 to 6 The present invention further includes the following steps when winding the yarn: First, the operator holds the yarn and pulls it out from the lead-in structure from right to left. Then, the pulled-out yarn is wound around the outside of the left reversing roller 36 from top to bottom. Then, the yarn is wound around the lower part of the tensioning wheel 353 from bottom to top. Then, the yarn is wound around the outside of the right reversing roller 36 from top to bottom. Then, the yarn is sequentially introduced into the interior of the limiting frame 31 and the guide frame 32. Then, the yarn passing through the right end of the guide frame 32 is connected to the outer surface of the drum.

[0062] The second step is to start the drum to rotate and wind the yarn. The extension section of the reciprocating hydraulic cylinder 2 drives the limit frame 31 to move back and forth. The limit frame 31 drives the guide frame 32 to move back and forth synchronously, so that the yarn is wound on the drum layer by layer and circle by circle.

[0063] The third step involves the yarn wound on the spool pulling on the guide frame 32. The pulling force of the yarn causes the guide frame 32 to deflect along its hinge point, while simultaneously compressing the spring telescopic rod 321. Thus, the pull impact force of the yarn is buffered by the guide frame 32 adaptively adjusting the deflection angle according to the pulling of the yarn.

[0064] In the fourth step, the limiting frame 31 pushes and pulls the moving plate 33 through the pull plate 34, so that the moving plate 33 drives the tensioning wheel 353 to move synchronously, so that the horizontal distance between the tensioning wheel 353 and the limiting frame 31 remains unchanged, thereby effectively preventing the limiting frame 31 from causing a large pulling impact on the yarn during the reciprocating movement.

[0065] Fifth, the moving plate 33 drives the L-shaped plate 354 to move synchronously, so that the L-shaped plate 354 drives the linkage column 355 to move along the inclined groove, so that the tensioning force of the tensioning wheel 353 on the yarn can be dynamically adjusted with the movement of the limiting frame 31, which further alleviates the instantaneous impact on the yarn when changing direction and effectively ensures more stable winding tension.

[0066] In the sixth step, when the drum rotates, the friction between the outer yarn roll and the rubber sleeve 436 drives the shaping roller 43 to rotate synchronously. This causes the shaping roller 43 to squeeze the yarn at both ends to the middle, effectively solving the problem of the yarn roll shoulder. As the outer diameter of the yarn roll gradually increases, the spiral spring automatically increases the resistance of the shaping roller 43 to the yarn roll, thereby adaptively adjusting the shaping intensity of the yarn roll and effectively ensuring the shaping effect.

[0067] In the seventh step, when the shaping roller 43 drives the scraper 434 to push the rubber sleeve 436 into contact with the yarn roll, the groove roller 432 pulls the scraper 434 to move closer to the T-shaped roller frame 42, so that the scraper 434 pushes the rubber sleeve 436 to further shape the yarn roll in a peristaltic pushing manner, preventing the occurrence of shoulder phenomenon.

[0068] In the eighth step, as the outer diameter of the yarn roll increases, the rotation speed of the scraper 434 and the counterweight 435 increases synchronously, causing the counterweight 435 to push the scraper 434 radially outward along the shaping roller 43 under the centrifugal effect, increasing the radial squeezing force of the scraper 434 on the yarn. By dynamically increasing the force to adjust the shaping intensity, the shaping effect is further guaranteed.
