Description

Technical Field

[0001] The invention relates to the technical field of glass fiber processing, and in particular to an automatic yarn-breaking glass fiber drawing machine and a use method thereof. Background Art

[0002] The glass fiber drawing machine is a mechanical equipment that draws molten glass into fiber filaments at high speed and winds them into fiber rolls according to a certain pattern. It consists of a machine body, crucible, tank kiln, drawing machine and temperature control system. The molten glass fiber is wound and sheared through a winding drum to facilitate the replacement of the winding drum.

[0003] A Chinese invention patent with announcement number CN117185647B discloses an automatic yarn-breaking glass fiber drawing machine and a method of using the machine, which includes a control body and a winding roller rotatably connected to one side of the control body, and also includes a mounting frame installed above the winding roller, wherein a cutter is movably installed inside the mounting frame; an extrusion member, wherein the extrusion member includes a storage bag arranged inside a cavity, wherein a rectangular plate is attached to the upper surface of the storage bag, wherein the rectangular plate is fixedly connected to a driven plate by two sets of symmetrically arranged connecting rods, and the driven plate is a trapezoidal structure, which is convenient for driving the rectangular plate to extrude the storage bag.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the above-mentioned glass fiber drawing machine uses a cutter to cut multiple glass fibers at the same time, and does not limit the glass fibers. Adjacent glass fibers are prone to skew after being acted upon by the cutter and before they break. After the glass fibers are cut, the skewness of the glass fibers easily causes the adjacent glass fiber ends to contact each other, which has a certain impact on the winding quality of the glass fibers and increases the difficulty for the staff to separate the glass fibers that are in contact with each other. Therefore, it is necessary to improve the design of the related technologies. Summary of the invention

[0013] By adopting the above technical solution, the electric push rod drives the push rod to move after working, and the movable plate, movable rod and push plate move synchronously. In this project, the fixed pulley gradually moves from the groove part of the sawtooth groove along the inclined surface of the sawtooth groove to the surface of the push plate close to the mounting frame. After the fixed pulley is squeezed by the push plate, the spring is compressed through the connecting plate, so that the driving rod and the mounting plate move synchronously, and the mounting plates on both sides gradually approach each other, so that the blade of the first cutter cooperates with the knife groove of the second cutter to cut the glass fiber.

[0014] Furthermore, a clamping mechanism for clamping the cut end of the glass fiber filament under the power of the electric push rod is provided on the device body, and the clamping mechanism includes a clamping assembly, and the clamping assembly is provided with two groups and symmetrically distributed on the side of the two movable rods away from each other; each group of the clamping assembly includes two groups of clamping units symmetrically arranged up and down, and each group of the clamping units includes a rotating tube that is penetrated and rotatably connected to the side wall of the device body, a bending rod fixed on the rotating tube, and a clamping block fixed to the end of the bending rod away from the rotating tube, and a rubber strip is fixed on the side of the clamping block away from the rotating tube.

[0025] 2. In the present application, after the electric push rod drives the push rod to move, the transmission rod in the rotating ring enters the spiral groove from the straight groove and causes the rotating ring to rotate. The rotating ring pulls the upper rotating tube on one side to rotate through the first connecting rod and the first traction rod, and at the same time pulls the lower rotating tube on the other side to rotate through the second connecting rod and the second traction rod. Under the action of four gears, the four rotating tubes all rotate, so that the bending rod and the clamping block rotate around the corresponding rotating tube, so that the rubber strips on the clamping blocks on both sides cooperate and clamp the cut glass fiber thread ends, further ensuring the stability of the glass fiber yarn during the yarn breaking process.

[0046] like Figure 1-11 As shown, an embodiment of the present application discloses an automatic yarn-breaking glass fiber drawing machine, comprising a device body 1, a pay-off roller 11 and a take-up roller 12 are rotatably installed on one side of the device body 1, a mounting frame 2 located between the pay-off roller 11 and the take-up roller 12 is fixed on one side of the device body 1, and two groups of mounting frames 2 are provided and symmetrically arranged, and a cutting mechanism 3 for simultaneously cutting multiple glass fiber filaments 4 is commonly installed on the device body 1 and the mounting frame 2, and the cutting mechanism 3 comprises a mounting assembly 31, and the mounting assembly 31 is provided with two groups and is respectively located on two mounting frames 2, and the two groups of mounting assemblies 31 cooperate and separate the multiple glass fiber filaments 4 to be cut from each other, and the cutting mechanism 3 also comprises a driving assembly 32 arranged on the device body 1 and used to drive the two groups of mounting assemblies 31 to approach or move away from each other, and a cutting assembly 33 arranged on the mounting assembly 31.

[0047] It is worth mentioning that when cutting the glass fiber yarn 4, the staff can drive the two groups of installation components 31 to approach each other through the driving component 32, and the installation components 31 on both sides cooperate to separate the multiple glass fiber yarns 4 to be cut from each other. Subsequently, the cutting component 33 performs the yarn cutting operation on the glass fiber yarn 4, which changes the phenomenon in traditional technology that the glass fiber yarn 4 is easily skewed after being subjected to shear force, and the ends of the glass fiber yarn 4 after the yarn is cut are entangled with each other, which is beneficial to improving the yarn cutting quality of the glass fiber yarn 4.

[0048] The mounting assembly 31 includes a mounting plate 311 arranged between two mounting frames 2 and a limiting plate 312 fixed to the side of the mounting plate 311 away from the mounting frame 2. The cross-section of the limiting plate 312 is a right-angled trapezoid. The limiting plates 312 are arranged in groups. The sides of the two limiting plates 312 in the same group that are close to each other are inclined surfaces. The distance between the sides of the two limiting plates 312 in the same group that are close to each other increases from the mounting plate 311 to the side away from the mounting frame 2. The limiting plates 312 on the two mounting frames 2 are staggered up and down.

[0049] It is worth mentioning that: in the process of the driving component 32 driving the two groups of installation components 31 to approach each other, the limiting plates 312 of the same group on both sides cooperate with each other to separate the glass fiber yarns 4 from each other, which plays a good limiting role in the subsequent cutting process of the glass fiber yarns 4 and is beneficial to enhancing the cutting quality of the glass fiber yarns 4.

[0050] The cutting assembly 33 includes a first cutter 331 detachably mounted on one of the mounting plates 311 and a second cutter 332 detachably mounted on the other mounting plate 311. A knife groove 3321 matching with the blade of the first cutter 331 is provided on a side of the second cutter 332 close to the first cutter 331. The driving assembly 32 includes an electric push rod 321 fixed in the device body 1, a push rod 322 fixed to the end of the output rod of the electric push rod 321, a movable plate 323 fixed to one end of the push rod 322 away from the electric push rod 321, and a movable rod 324 fixed to the side of the movable plate 323 away from the electric push rod 321. The movable rod 324 penetrates the side wall of the device body 1 and slides together. Two movable rods 324 are provided and are respectively located on the sides of the two mounting frames 2 away from each other. A push plate 325 is fixed to each movable rod 324. The driving assembly 32 further includes a driving unit 326 disposed on the mounting frame 2 and driving the mounting plate 311 to move toward or away from the mounting frame 2 under the action of the push plate 325 . The driving unit 326 is evenly disposed in multiple groups. Each set of driving units 326 includes a driving rod 3261 that is penetrated and slidably matched on the mounting frame 2, a connecting plate 3262 fixed to the end of the driving rod 3261 away from the mounting plate 311, a spring 3263 that is sleeved on the driving rod 3261 and fixed between the connecting plate 3262 and the mounting frame 2, and a fixed pulley 3264 rotatably mounted on the side of the connecting plate 3262 away from the mounting plate 311. The end of the driving rod 3261 away from the movable rod 324 is fixed to the side of the mounting plate 311 close to the mounting frame 2, and a serrated groove 3251 is provided on the side of the push plate 325 close to the mounting plate 311 for the fixed pulley 3264 to slidably match. When the fixed pulley 3264 abuts against the side of the push plate 325 close to the mounting plate 311, the blade of the first cutter 331 is just engaged with the knife groove 3321 on the second cutter 332.

[0051] It is worth mentioning that after the electric push rod 321 works, it drives the push rod 322 to move, and the movable plate 323, the movable rod 324 and the push plate 325 move synchronously. In this project, the fixed pulley 3264 gradually moves from the groove part of the sawtooth groove 3251 along the inclined surface of the sawtooth groove 3251 to the surface of the push plate 325 close to the mounting frame 2. After the fixed pulley 3264 is squeezed by the push plate 325, the spring 3263 is compressed through the connecting plate 3262, so that the driving rod 3261 and the mounting plate 311 move synchronously, and the mounting plates 311 on both sides gradually approach each other, so that the blade of the first cutter 331 cooperates with the knife groove 3321 of the second cutter 332 to cut the glass fiber 4.

[0052] The device body 1 is provided with a clamping mechanism 5 for clamping the cut ends of the glass fiber 4 under the power of the electric push rod 321. The clamping mechanism 5 includes a clamping assembly 51. The clamping assembly 51 is provided with two groups and symmetrically distributed on the side away from each other of the two movable rods 324. Each group of clamping components 51 includes two groups of clamping units 511 symmetrically arranged in the upper and lower parts. Each group of clamping units 511 includes a rotating tube 5111 that is penetrated and rotatably connected to the side wall of the device body 1, a bending rod 5112 fixed on the rotating tube 5111, and a clamping block 5113 fixed to the end of the bending rod 5112 away from the rotating tube 5111. A rubber strip 5114 is fixed to the side of the clamping block 5113 away from the rotating tube 5111. The clamping mechanism 5 also includes a transmission component 52 for driving the two rotating tubes 5111 in the same group to rotate in opposite directions, and the two rotating tubes 5111 in the opposite group also rotate in opposite directions. When the blade of the first cutter 331 is just engaged with the knife groove 3321 on the second cutter 332, the rubber strips 5114 on the two clamping blocks 5113 on both sides cooperate and clamp the glass fiber filament 4.

[0053] The transmission assembly 52 includes a U-shaped plate 521 fixed on the inner wall of the device body 1, a rotating ring 522 rotatably mounted on the side of the U-shaped plate 521 away from the inner wall of the device body 1, a first connecting rod 523 fixed on one side of the rotating ring 522, a first traction rod 524 hinged to the side of the first connecting rod 523 away from the rotating ring 522 (the first traction rod 524 consists of two mutually hinged rods, one of the ends of the first traction rod 524 is hinged to the first connecting rod 523), a second connecting rod 525 rotatably mounted on the other side of the rotating ring 522, and a second traction rod 526 hinged to the side of the second connecting rod 525 away from the rotating ring 522 (the second traction rod 526 also consists of two mutually hinged rods, one of the ends of the second traction rod 526 is hinged to the second connecting rod 525), the push rod 322 passes through the U-shaped plate 521 and is clearance-fitted, and the first traction rod 524 (the rod body of the first traction rod 524 away from the side of the first connecting rod 523) is fixedly mounted on the upper rotating tube 5111 of the clamping unit 511 on one side, and the second traction rod 526 (the rod body of the second traction rod 526 away from the side of the second connecting rod 525) is fixedly mounted on the lower rotating tube 5111 of the clamping unit 511 on the other side. A gear 51111 is fixedly mounted on each rotating tube 5111, and the gears 51111 on the two rotating tubes 5111 on the same side are meshed with each other. A transmission rod 527 is fixed to the inner wall of the rotating ring 522, and a transmission groove 3221 that slidably cooperates with the transmission rod 527 is formed on the side wall of the pushing rod 322. The transmission groove 3221 includes a spiral groove 32211 that drives the rotating ring 522 to rotate through the transmission rod 527 under the pushing action of the electric push rod 321, and a straight groove 32212 connected to the end of the spiral groove 32211.

[0054] It is worth noting that: after the electric push rod 321 drives the push rod 322 to move, the transmission rod 527 in the rotating ring 522 enters the spiral groove 32211 from the straight groove 32212 and causes the rotating ring 522 to rotate. The rotating ring 522 pulls the upper rotating tube 5111 on one side to rotate through the first connecting rod 523 and the first traction rod 524, and at the same time pulls the lower rotating tube 5111 on the other side to rotate through the second connecting rod 525 and the second traction rod 526. Under the action of the four gears 51111, the four rotating tubes 5111 all rotate, so that the bending rod 5112 and the clamping block 5113 rotate around the corresponding rotating tube 5111, so that the rubber strips 5114 on the clamping blocks 5113 on both sides cooperate and clamp the cut glass fiber yarn 4 thread ends, further ensuring the stability of the glass fiber yarn 4 during the yarn breaking process.

[0055] An open groove 51131 is provided on one side of the clamping block 5113 away from the bending rod 5112. A suction mechanism 6 for sucking debris generated during the cutting of the glass fiber yarn 4 is installed on the device body 1 and the rotating tube 5111. The suction mechanism 6 includes an air suction pipe 61 for fixing and connecting the rotating tube 5111 and the open groove 51131, a transfer box 62 arranged in the device body 1 and connected to the air suction pipe 61, a convergence pipe 63 fixed and connected to the top of the transfer box 62, a conveying pipe 64 fixed and connected to the top of the convergence pipe 63, an exhaust fan 65 fixed and connected to the conveying pipe 64, and an integrated box 66 fixed to the inner wall of the device body 1. The transfer box 62 is provided with two and is symmetrically arranged. The output pipe of the exhaust fan 65 is fixed and connected to the bottom of the integrated box 66, and the top of the integrated box 66 is fixed and connected to an exhaust pipe 67 leading to the outside of the device body 1.

[0056] It is worth mentioning that: some debris is usually generated during the breaking process of the glass fiber yarn 4. In order to centrally process the debris, the staff only needs to start the exhaust fan 65, and collect the debris generated during the cutting process of the glass fiber yarn 4 through the suction pipe 61, the rotating pipe 5111, the transfer box 62, the converging pipe 63, the conveying pipe 64, the exhaust fan 65, the integrated box 66 and the exhaust pipe 67 in sequence (to improve the processing effect, the exhaust pipe 67 can be connected to the purification box and other processing equipment) and centrally process it.

[0057] The operating principle of an automatic yarn-breaking glass fiber drawing machine in the present embodiment is: when cutting the glass fiber yarn 4, the staff can drive the two groups of installation components 31 to approach each other through the driving component 32, and the installation components 31 on both sides cooperate and separate the multiple glass fiber yarns 4 to be cut from each other. Subsequently, the cutting component 33 performs the yarn-breaking operation on the glass fiber yarn 4, which changes the phenomenon in traditional technology that the glass fiber yarn 4 is easily skewed after being subjected to shear force, and the thread ends of the glass fiber yarn 4 after the yarn is broken are entangled with each other, which is beneficial to improving the yarn-breaking quality of the glass fiber yarn 4.

[0058] This embodiment also discloses a method for using an automatic yarn-breaking glass fiber drawing machine, comprising the following steps:

[0059] S1. When cutting the glass fiber filament 4, the electric push rod 321 is started.
