Description

Technical Field

[0001] This invention relates to a glass fiber production equipment, and more particularly to a glass fiber production equipment and its production process. Background Technology

[0002] Fiberglass production equipment is a machine used to manufacture fiberglass. Its working principle involves using special processes and technologies to calcine and mix raw glass (usually silica, dolomite, alumina, etc.) to produce glass powder. This glass powder is then mixed evenly with various additives (such as fluxes and reinforcing agents). Next, the mixed glass powder is heated above its melting point through pressure or stretching, forming very fine filaments. These filaments have a continuous structure at this stage. Finally, these filaments are cooled and cut into glass fibers of a certain length, thus forming the fiberglass. Subsequent processing, such as twisting, weaving, and relaxing, using a fiber-making machine, produces fiberglass products of different materials, types, and specifications, such as fiberglass cloth, tubes, and sheets.

[0003] In existing glass fiber production, as shown in the patented fully automated glass fiber filament preparation system (publication number CN116813192A), the collection of glass fibers generally adopts a winding transition method, and after winding to a certain length, it is segmented and cut to complete the formation of a roll of glass fiber for subsequent product processing and use. However, since it is difficult to automate the winding and rewinding of filamentous glass fibers, manual intervention is inevitable. The more manual intervention there is, the greater the safety risks for workers, and it is also more time-consuming and labor-intensive, which greatly reduces production efficiency. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a glass fiber production equipment and its production process, so that the automatic transition operation of the first section of filamentous glass fiber can be completed when a roll of glass fiber is formed, that is, there is no need for manual roll changing, and there is also no need for manual positioning operation of the first section after slitting. Therefore, it is more time-saving and labor-saving, and the production efficiency can be greatly improved.

[0005] Meanwhile, the detachable and modular installation structure allows for the determination of the number of accumulated take-up rollers as needed, and the installation of pressure bars and cutters based on the number of take-up rollers. This provides greater flexibility. Furthermore, when the entire equipment performs the initial pressing and final cutting, regardless of the number of accumulated take-up rollers, it only requires one set of drive cylinders, thus achieving greater energy savings and significantly reducing production costs.

[0006] This invention provides the following technical solution:

[0007] A glass fiber production equipment and process thereof includes a fiber guide and a fiber winding machine. The fiber guide is used to guide the drawn glass fiber in the melting box to the fiber winding machine for winding. The fiber winding machine includes a winding unit, which includes a rotating shaft driven by a winding motor, multiple winding drums axially guided and connected to the rotating shaft, and a first-section pressing part corresponding to each winding drum. The first-section pressing part includes a bushing and a pressing mechanism positioned on the bushing. The bushing is also axially guided and connected to the rotating shaft, and is spaced apart from the winding drums. Each group of winding drums has a set of pressing parts arranged on one side in the same direction. The glass fiber is cut and slit into sections, and a pressing mechanism is used to position the first section of glass fiber. The two ends of the rotating shaft are also threaded with two sets of locking nuts. The two sets of locking nuts are used to lock the bushing and take-up drum, which are fitted into the rotating shaft, axially. Thus, the locking nuts can be turned according to the number of take-up drums to lock the position of the take-up drum. This is simple, convenient and flexible. The locked take-up drum and the first section pressing part can rotate with the rotating shaft under the drive of the winding motor. The take-up drum is used for rotating and winding the fiber, while the first section pressing part is used to press and position the first section of glass fiber of each take-up drum.

[0008] Preferably, in order to reduce the production cost of the first section of the pressing part, the cutting and pressing operations can be set to be performed by the same set of driving equipment. Based on this, it is necessary to ensure that the pressing mechanism can maintain the pressing operation even if the driving equipment is subsequently withdrawn after pressing. At the same time, it is also necessary to ensure that it can be quickly disassembled and reassembled after subsequent roll changes to further reduce production costs. On this basis, the pressing mechanism can be set to include fixed rod one, fixed rod two, inclined block one, inclined block two, guide sleeve, pressure block, spring one, locking block and positioning spring pressure group. Fixed rod one and fixed rod two are arranged in parallel and are vertically positioned on the bushing. Fixed rod one is closer to the corresponding take-up drum than fixed rod two, and its height is set lower than the height of fixed rod one.

[0009] One end of the guide sleeve is fitted over the fixed rod one, and the other end is slidably fitted with a ramp block one along the axial direction of the rotation axis. A ramp block two is fitted over the fixed rod two. The positioned ramp block one and ramp block two have two sets of sliding contact surfaces that abut against each other. These two sets of sliding contact surfaces are located between the fixed rod one and the fixed rod two and are inclined surfaces. The two sets of sliding surfaces are slidably connected in their inclined direction, and when their inclined direction extends towards the bushing, they intersect with the positioning rod two. This ensures that when ramp block two is pressed down, ramp block one can be driven to simultaneously press down and move towards the end of the corresponding winding drum. Closer to the inclined block, on the side opposite to the inclined block two, a set of pressure blocks is also provided for pressing the first section of the glass fiber against the end of the take-up drum. That is, pressing down on the inclined block two allows the inclined block to move closer to the corresponding take-up drum simultaneously through the inclined sliding surface. Thus, before pressing down on the inclined block one, the pressure blocks are distributed away from the take-up drum. Therefore, when the fiber guide machine guides the glass fiber to the end, it will not cause interference with the glass fiber. After the glass fiber abuts against the end of the take-up drum, pressing down on the inclined block two allows the pressure blocks to move closer to the end of the take-up drum simultaneously. The pressure block is pressed against the glass fiber at the end of the take-up drum, thus positioning the glass fiber for subsequent slitting by the cutter. As the rotating shaft rotates, the first segment of glass fiber remains pressed under the pressure block and rotates with the shaft until the first segment is wound up. To ensure that the pressure block remains away from the take-up drum initially, avoiding interference during the winding of the first segment, a spring is installed at the bottom of the groove where the fixed rod engages with the guide sleeve. This spring presses the inclined block away from the bushing via the guide sleeve, thereby ensuring initial... In the initial state, the pressure block can be moved away from the take-up drum. The end of the fixed rod one is also provided with a locking block. The locking block is limited in the guide sleeve and is used to connect the positioning rod to limit the fixed rod one in the guide sleeve to prevent the fixed rod one from detaching from the guide sleeve. The fixed rod two is provided with a set of positioning spring pressure group. The positioning spring pressure group is limited in the inclined block two. When the inclined block two is pressed to push the inclined block one, and the pressure block presses against the end of the take-up drum to press and position the first section of glass fiber, the positioning spring pressure group will disengage from the inclined block two and pop out the fixed rod two to press against one side of the inclined block two, so that the pressure block remains in the state of pressing against the end of the take-up drum.

[0010] Preferably, the positioning spring assembly includes a rectangular spring block, a piston rod, a piston block, and a second spring. The second fixed rod has two sets of spring-loaded grooves. One end of the piston rod is connected to the piston block and placed in one set of spring-loaded grooves, while the other end is connected to the rectangular spring block and placed in the other set of spring-loaded grooves. Under the push of the second spring, the piston block pushes the rectangular spring block out of the spring-loaded groove to press and limit it on one side of the inclined block, so that the pressure block keeps pressing against the end of the winding drum. When the first pressing part needs to be disassembled and reused, it is only necessary to press the rectangular spring block to compress the second spring again and retract it into the second fixed rod. The first spring pushes the first inclined block, so that the second inclined block can move along the second fixed rod again, thus limiting the positioning spring assembly in the guide hole of the second inclined block. It is also convenient to restore the original state and reuse it.

[0011] Preferably, the fiber guide includes a fiber guide slide, a fiber guide screw, a fiber guide block, and a fiber guide hole. The two ends of the fiber guide screw are mounted on the fiber guide slide and are driven to rotate by a fiber guide motor mounted on the fiber guide slide. A fiber guide block corresponding to a take-up drum is screwed onto the screw. One end of the fiber guide block is slidably mounted on the fiber guide slide, and the other end is provided with a fiber guide hole for guiding the glass fiber through. Thus, by driving the fiber guide screw to rotate forward and backward, the fiber guide block can be driven to reciprocate, so that the glass fiber can be evenly wound around the middle of the take-up drum. When winding the first section of glass fiber, the fiber guide block can be driven to move to the end of the take-up drum and, together with the pressure block, position the glass fiber.

[0012] Preferably, the winding machine further includes a rotating frame, a fixed frame, a pressure frame, a fixed shaft, a drive motor, a cutter, and a pressure rod. The two ends of the fixed shaft are fixed to the fixed frame, and a set of rotating frames is externally mounted thereon. The rotating frame has four sets of winding units evenly distributed in the circumferential direction, and the rotation axis of the winding unit is parallel to the fixed shaft. A set of drive motors is also mounted on the fixed frame. One end of the rotating frame is fixed with a meshing gear for engaging with the drive wheel of the drive motor. The two ends of the pressure frame are also positioned on the fixed frame, and pressure cylinders are mounted on them. The drive end of the pressure cylinder is connected to a set of mounting rods. The mounting rods are equipped with cutters and pressure rods that correspond one-to-one with the winding drum. The cutter is positioned at the end of the winding drum to cut the glass fiber guided into place by the fiber guide. The pressure rod is positioned above the corresponding inclined block two and presses down to drive the inclined block two, so that the pressure block simultaneously presses against the first segment of the cut glass fiber when the cutter cuts the glass fiber.

[0013] At this point, once a set of winding units has completed winding, the drive motor can rotate the turntable 90°, causing the next set of winding units to rotate below the pressure frame. Simultaneously, the guide motor drives the corresponding strand of glass fiber to move to the end of each set of winding drums. Then, the pressure cylinder drives the mounting rod to press down close to the winding unit. When the pressure rod contacts the inclined block two, the pressure block moves towards the end of the winding drum under the drive of the inclined block two. When the pressure block presses against the glass fiber at the end of the winding drum, the cutter also contacts the end of the winding drum, thereby achieving the cutting of the glass fiber. The glass fiber is slit and pressed against the first section of the slit glass fiber to be wound up. At the same time, the positioning spring pressure group comes out from the second inclined block and presses against one side of the second inclined block, so that the pressure block keeps pressing against the end of the winding drum. Then, the pressure cylinder drives the mounting rod to move up away from the winding unit, and the winding motor drives the rotating shaft to rotate to wind up the glass fiber. During winding, the pressure block also rotates with the rotating shaft, and the guide moves along the axial direction of the rotating shaft to the middle of the winding drum. In the linear reciprocating motion of the guide, the glass fiber is evenly wound to the middle of the winding drum.

[0014] Preferably, the rotating frame is equipped with a quick-release clamp to achieve the installation and positioning of the winding unit. The quick-release clamp includes a lead screw mounted on the rotating frame and driven to rotate by a lead screw motor, and two sets of positioning frames screwed in opposite directions to the lead screw. The lead screw and the rotating shaft are distributed in parallel. One end of the two sets of positioning frames is slidably mounted on the rotating frame, and the other end is sleeved and connected to the short shaft at the end of the rotating shaft. The end of the short shaft is also provided with a rectangular transmission block. The winding motor is mounted on one set of positioning frames, and its driving end is also provided with a rectangular transmission groove that is inserted and connected to the rectangular transmission block. The diameter of the rectangular outer circle of the rectangular transmission block, the diameter of the short shaft, and the diameter of the rotating shaft increase in sequence.

[0015] At this point, once a set of winding units has completed winding and rotated to the bottom of the rotating frame, a support frame is installed at the bottom to support the winding drum. Then, the lead screw motor is started to drive the lead screw to rotate, causing the two sets of positioning frames to move away from each other. During the away movement, the two sets of positioning frames disengage from the short shaft, and the drive end of the winding motor disengages from the rectangular transmission block. Then, the conveyor drives the winding unit carrying the completed winding away from the support frame. At the same time, the next empty winding unit is supported by the support frame and moved to the bottom of the rotating frame. Then, the lead screw motor is started again to make the lead screw rotate in the opposite direction, and the two sets of positioning frames move towards each other. During the towards-each-other movement, the two sets of positioning frames are fitted into the short shaft until they abut against the end of the rotating shaft. At the same time, the rectangular transmission block at one end of the short shaft is also inserted and installed into the rectangular transmission groove at the drive end of the winding motor. Then, the rotating frame is waited for to rotate again so that the installed winding unit moves to the top to await the winding operation.

[0016] A manufacturing process for a glass fiber production equipment, based on the aforementioned glass fiber production equipment, includes the following steps:

[0017] S1: First, four sets of winding units are installed on the rotating frame. At the start of production, the glass fiber in the melting box is guided to the end of the winding drum of the first set of winding units below the pressure frame, and the initial glass fiber is positioned by the pressing mechanism. Then, the winding motor drives the rotating shaft to rotate to wind the glass fiber. During winding, the pressure block also rotates with the rotating shaft, and the guide moves along the axial direction of the rotating shaft to the middle of the winding drum. In the linear reciprocating motion of the guide, the glass fiber is evenly wound to the middle of the winding drum.

[0018] S2: After the first winding unit completes winding, the drive motor drives the rotating frame to rotate 90° away from the guide machine, causing the next winding unit to rotate to below the pressure frame. At the same time, the guide machine drives the corresponding strand of glass fiber to move to the end of each winding drum. Then, the pressure cylinder presses down again to drive the pressing mechanism to complete the cutting and positioning of the first segment of the initial glass fiber. The specific cutting and positioning steps are as follows:

[0019] The pressure cylinder is activated, causing the mounting rod to press down and approach the winding unit. When the pressure rod contacts the second inclined block, the pressure block moves towards the end of the winding drum under the drive of the second inclined block. When the pressure block presses against the glass fiber at the end of the winding drum, the cutter also contacts the end of the winding drum, thereby achieving the slitting of the glass fiber. The pressure block presses against the first section of the glass fiber to be wound after slitting. At the same time, the positioning spring pressure group comes out from the second inclined block and presses against one side of the second inclined block, so that the pressure block remains in the state of pressing against the end of the winding drum. Then, the pressure cylinder drives the mounting rod to move up away from the winding unit, and the winding motor drives the rotating shaft to rotate to wind the glass fiber. After winding, the rotating frame rotates 90° away from the guide machine again, so that the next winding unit rotates to the bottom of the pressure frame, and the winding operation is repeated.

[0020] S3: When the winding unit completes winding and rotates to the bottom of the rotating frame, the support frame below the rotating frame supports the winding drum. Then, the lead screw motor is started to drive the lead screw to rotate, causing the two sets of positioning frames to move away from each other. During the away movement, the two sets of positioning frames disengage from the short shaft, and the drive end of the winding motor disengages from the rectangular transmission block. Then, the conveyor used to drive the support frame to move is started to move the winding unit carrying the completed winding away. At the same time, the next set of empty winding units is supported by the support frame and moved to the bottom of the rotating frame. Then, the lead screw motor is started again to make the lead screw rotate in the opposite direction, and the two sets of positioning frames move towards each other. During the towards-each-other movement, the two sets of positioning frames are fitted into the short shaft until they abut against the end of the rotating shaft. At the same time, the rectangular transmission block at one end of the short shaft is also inserted and installed into the rectangular transmission groove at the drive end of the winding motor. Then, wait for the rotating frame to rotate again so that the installed winding unit moves to the bottom of the pressure frame for winding.

[0021] The beneficial effects of this invention are:

[0022] In this invention, the automated transition operation of the first section of filamentous glass fiber can be completed during the forming of a roll of glass fiber. That is, there is no need for manual roll changing, nor is there a need for manual positioning of the first section after slitting. Therefore, it is more time-saving and labor-saving, and the production efficiency can be greatly improved. At the same time, the detachable and combinable installation structure can determine the number of accumulated take-up rollers as needed, and then install the pressure bar and cutter according to the number of take-up rollers. This provides greater flexibility. Moreover, when the whole equipment performs the first section pressing and the final slitting, regardless of the number of accumulated take-up rollers, it only requires one set of drive cylinders. Therefore, it is more energy-efficient and the production cost is greatly reduced.

[0023] In this invention, the position of the take-up drum can be locked by turning the locking nut according to the cumulative number of take-up drums, which is simpler, more convenient, and more flexible. The locked take-up drum and the first section pressing part can rotate with the rotating shaft under the drive of the winding motor. The take-up drum is used for rotating winding, while the first section pressing part is used for pressing and positioning the first section of glass fiber for each take-up drum.

[0024] In this invention, before the first pressure inclined block, the pressure blocks are distributed far away from the take-up drum. Therefore, when the guide machine guides the glass fiber to the end, it will not cause interference with the glass fiber. After the glass fiber abuts against the end of the take-up drum, the second pressure inclined block can be pressed down so that the pressure block can approach the end of the take-up drum while pressing down, until it presses against the glass fiber at the end of the take-up drum, thereby achieving pressure and positioning of the glass fiber for subsequent cutting by the cutter. When the rotating shaft rotates, the first segment of glass fiber after segmentation is still pressed under the pressure block and rotates with the rotating shaft until the first segment is wound up.

[0025] In this invention, when the first section of the pressing part needs to be disassembled and reused, it is only necessary to press the rectangular spring block to compress the spring two and retract it into the fixed rod two. The spring one pushes the inclined block one, which in turn allows the inclined block two to move along the fixed rod two again, so that the positioning spring pressing group is limited in the guide hole of the inclined block two, and it is also convenient to restore the original state and use it again.

[0036] Example 1

[0037] like Figure 1-4As shown, a glass fiber production equipment, in this embodiment, includes a guide machine 1 and a winding machine. The guide machine 1 is used to guide the drawn glass fiber in the melting box to the winding machine for winding. The winding machine includes a winding unit 2, which includes a rotating shaft 22 driven by a winding motor 21, multiple winding drums 23 axially guided and connected to the rotating shaft 22, and a first-section pressing part 24 corresponding to each winding drum 23. The first-section pressing part 24 includes a bushing 241 and a pressing mechanism positioned on the bushing 241. The bushing 241 is also axially guided and connected to the rotating shaft 22, and is spaced apart from the winding drums 23. Each group of winding drums 23 has a set of [unclear - possibly related to glass fiber production equipment] arranged on one side in the same direction. The glass fiber is cut and slit into sections. The clamping mechanism is used to position the first section of the glass fiber. The two ends of the rotating shaft 22 are also threaded with two sets of locking nuts 25. The two sets of locking nuts 25 are used to lock the bushing 241 and the take-up drum 23, which are fitted into the rotating shaft 22, along the axial direction. Thus, the locking nuts 25 can be turned according to the number of take-up drums 23 to lock the position of the take-up drum 23. This is simple, convenient and flexible. The locked take-up drum 23 and the first section clamping part 24 can rotate with the rotating shaft 22 under the drive of the winding motor 21. The take-up drum 23 is used for rotating and winding the fiber, while the first section clamping part 24 is used to clamp and position the first section of glass fiber of each take-up drum 23.

[0038] To reduce the production cost of the first section of the pressing part 24, the cutting and pressing operations can be performed by the same set of driving equipment. Based on this, it is necessary to ensure that the pressing mechanism can maintain the pressing operation even if the driving equipment is subsequently withdrawn after pressing. At the same time, it is also necessary to ensure that it can be quickly disassembled and reassembled after subsequent roll changes to further reduce production costs. On this basis, the pressing mechanism can be set to include fixed rod 1 242, fixed rod 243, inclined block 1 244, inclined block 2 245, guide sleeve 246, pressure block 247, spring 1 248, locking block 249 and positioning spring pressure group. Fixed rod 1 242 and fixed rod 2 243 are arranged in parallel and are vertically positioned on the bushing 241. Fixed rod 1 242 is closer to the corresponding take-up drum 23 than fixed rod 2 243, and its height is set lower than the height of fixed rod 1 242.

[0039] One end of the guide sleeve 246 is fitted over the fixed rod 242, and the other end is slidably fitted with a first inclined block 244 along the axial direction of the rotating shaft 22. A second inclined block 245 is fitted over the fixed rod 243. The positioned first inclined block 244 and second inclined block 245 have two sets of sliding contact surfaces that abut against each other. These two sets of sliding contact surfaces are located between the fixed rod 242 and the fixed rod 243 and are inclined surfaces. The two sets of sliding surfaces are slidably connected in their inclined direction, and when their inclined direction extends towards the bushing 241, they intersect with the second positioning rod. This ensures that when the second inclined block 245 is pressed down, the first inclined block 244 can be driven to move towards the end of the corresponding winding drum 23 simultaneously. Closer to the inclined block 244, on the side opposite to the inclined block 245, a set of pressure blocks 247 are also provided for pressing the first section of the glass fiber against the end of the take-up drum 23. That is, when the inclined block 245 is pressed down, the inclined block 244 can be driven by the inclined surface to press down and move closer to the corresponding take-up drum 23. Thus, before the inclined block 244 is pressed down, the pressure blocks 247 are distributed away from the take-up drum 23. Therefore, when the fiber guide machine 1 guides the glass fiber to the end, it will not cause interference with the glass fiber. After the glass fiber abuts against the end of the take-up drum 23, the inclined block 245 can be pressed down, so that the pressure blocks 247 can move closer to the end of the take-up drum 23 while pressing down, until they reach the end of the take-up drum 23. The glass fiber is pressed against the end of the take-up drum 23 to achieve pressure and positioning of the glass fiber for subsequent slitting by the cutter 8. When the rotating shaft 22 rotates, the first segment of glass fiber remains pressed against the pressure block 247 and rotates with the rotating shaft 22 until the first segment is wound up. To ensure that the pressure block 247 remains away from the take-up drum 23 in the initial state to avoid interference during the winding of the first segment, a set of springs 248 is provided at the bottom of the groove where the fixed rod 242 and the guide sleeve 246 are fitted. The springs 248 are used to press the inclined block 244 away from the bushing 241 through the guide sleeve 246, thereby ensuring that the pressure block 247 can be pressed away from the shaft sleeve 241 in the initial state. A stop block 249 is provided at the end of the fixed rod 242 away from the take-up drum 23. The stop block 249 is limited in the guide sleeve 246 and is used to connect the positioning rod to limit the fixed rod 242 in the guide sleeve 246 to prevent the fixed rod 242 from detaching from the guide sleeve 246. A set of positioning spring pressure group is provided in the fixed rod 243. The positioning spring pressure group is limited in the inclined block 245. When the inclined block 245 is pressed to push the inclined block 244 and the pressure block 247 presses against the end of the take-up drum 23 to press and position the first section of glass fiber, the positioning spring pressure group will be released from the inclined block 245 and the fixed rod 243 will be ejected to press against one side of the inclined block 245, so that the pressure block 247 remains in the state of pressing against the end of the take-up drum 23.

[0040] The positioning spring assembly includes a rectangular spring block 2410, a piston rod 2411, a piston block 2412, and a second spring 2413. The second spring rod 243 has two sets of spring-loaded grooves. One end of the piston rod 2411 is connected to the piston block 2412 and placed in one set of spring-loaded grooves, while the other end is connected to the rectangular spring block 2410 and placed in the other set of spring-loaded grooves. Under the pushing force of the second spring 2413, the piston block 2412 pushes the rectangular spring block 2410 out of the spring-loaded groove to press and limit it on one side of the inclined block 245, thus pressing the block... 247 maintains the state of pressing against the end of the winding drum 23. When the first pressing part 24 needs to be disassembled and reused, simply press the rectangular spring block 2410 to compress the spring 2413 again and retract it into the fixed rod 243. The spring 248 pushes the inclined block 244, which in turn allows the inclined block 245 to move along the fixed rod 243 again, so that the positioning spring assembly is limited in the guide hole of the inclined block 245, and it is convenient to restore the original state and use it again.

[0041] The fiber guide 1 includes a fiber guide slide 11, a fiber guide screw 12, a fiber guide block 13, and a fiber guide hole 14. The two ends of the fiber guide screw 12 are mounted on the fiber guide slide 11 and are driven to rotate by a fiber guide motor mounted on the fiber guide slide 11. A fiber guide block 13 corresponding to a take-up drum 23 is screwed onto the outside of the screw. One end of the fiber guide block 13 is slidably mounted on the fiber guide slide 11, and the other end is provided with a fiber guide hole 14 for guiding the glass fiber through. Thus, by driving the fiber guide screw 12 to rotate forward and backward, the fiber guide block 13 can be driven to reciprocate, so that the glass fiber can be evenly wound around the middle of the take-up drum 23. When winding the first section of the glass fiber, the fiber guide block 13 can be driven to move to the end of the take-up drum 23, and the pressure block 247 can be used to position the glass fiber.

[0042] Example 2

[0043] like Figure 5-7As shown, a glass fiber production equipment and its production process, in this embodiment, is a further limitation based on Embodiment 1. The winding machine also includes a rotating frame 3, a fixed frame 4, a pressure frame 5, a fixed shaft 6, a drive motor 7, a cutter 8, and a pressure rod 9. Both ends of the fixed shaft 6 are fixed to the fixed frame 4, and a set of rotating frames 3 are externally mounted thereon. Four sets of winding units 2 are evenly distributed along the circumference of the rotating frame 3, and the rotation shaft 22 of the winding unit 2 is arranged parallel to the fixed shaft 6. A set of drive motors 7 is also mounted on the fixed frame 4, and one end of the rotating frame 3 is fixed with a device for connecting to the drive motor. The drive wheel of 7 is driven by a meshing gear. Both ends of the pressure frame 5 are also positioned on the fixed frame 4, and a pressure cylinder is installed on it. The drive end of the pressure cylinder is connected to a set of mounting rods. The mounting rods are equipped with cutters 8 and pressure rods 9 that correspond one-to-one with the take-up drum 23. The cutter 8 is positioned at the end of the take-up drum 23 to cut the glass fiber that has been guided into place by the guide machine 1. The pressure rod 9 is positioned above the corresponding inclined block 245 and presses down to drive the inclined block 245 so that the pressure block 247 presses against the first segment of the cut glass fiber simultaneously when the cutter 8 cuts the glass fiber.

[0044] At this point, after a set of winding units 2 has completed winding, the drive motor 7 can drive the rotating frame 3 to rotate 90°, causing the next set of winding units 2 to rotate below the pressure frame 5. At the same time, the guide machine 1 drives the corresponding strand of glass fiber to move to the end of each set of winding drums 23. Then, the pressure cylinder drives the mounting rod to press down close to the winding unit 2. When the pressure rod 9 contacts the inclined block 245, the pressure block 247 moves towards the end of the winding drum 23 under the drive of the inclined block 245. When the pressure block 247 presses against the glass fiber at the end of the winding drum 23, the cutter 8 also contacts the end of the winding drum 23, thereby achieving the slitting of the glass fiber. The pressure block 247 presses against the first section of the glass fiber to be wound after slitting, while the positioning spring pressure group comes out from the inclined block 245 and presses against one side of the inclined block 245, so that the pressure block 247 keeps pressing against the end of the winding drum 23. Then, the pressure cylinder drives the mounting rod to move up away from the winding unit 2, and the winding motor 21 drives the rotating shaft 22 to rotate to wind the glass fiber. During winding, the pressure block 247 also rotates with the rotating shaft 22, and the guide machine 1 moves along the axial direction of the rotating shaft 22 to the middle of the winding drum 23. In the linear reciprocating motion of the guide machine 1, the glass fiber is evenly wound to the middle of the winding drum 23.

[0045] The rotating frame 3 is equipped with a quick-release clamp to achieve the installation and positioning of the winding unit 2. The quick-release clamp includes a lead screw that is mounted on the rotating frame 3 and driven to rotate by a lead screw motor, and two sets of positioning frames that are screwed in the opposite direction to the lead screw. The lead screw and the rotating shaft 22 are distributed in parallel. One end of the two sets of positioning frames is slidably mounted on the rotating frame 3, and the other end is connected to the short shaft sleeve 241 at the end of the rotating shaft 22. The end of the short shaft is also provided with a rectangular transmission block. The winding motor 21 is mounted on a set of positioning frames. Its drive end is also provided with a rectangular transmission groove that is inserted and connected to the rectangular transmission block. The diameter of the rectangular outer circle of the rectangular transmission block, the diameter of the short shaft, and the diameter of the rotating shaft 22 increase in sequence.

[0046] At this point, after a set of winding units 2 has completed winding and rotated to the bottom by the rotating frame 3, a support frame is set at the bottom to support the winding drum 23. Then, the lead screw motor is started to drive the lead screw to rotate, causing the two sets of positioning frames to move away from each other. During the away movement, the two sets of positioning frames disengage from the short shaft, and the drive end of the winding motor 21 disengages from the rectangular transmission block. Then, the conveyor drives the winding unit 2 carrying the completed winding away from the support frame. At the same time, the next set of empty winding units 2 is supported by the support frame and moved to the bottom of the rotating frame 3. Then, the lead screw motor is started again to make the lead screw rotate in the opposite direction, and the two sets of positioning frames move towards each other. During the towards-each-other movement, the two sets of positioning frames are fitted into the short shaft until they abut against the end of the rotating shaft 22. At the same time, the rectangular transmission block at one end of the short shaft is also inserted and installed into the rectangular transmission groove at the drive end of the winding motor 21. Then, wait for the rotating frame 3 to rotate again so that the installed winding unit 2 moves to the top to wait for the winding operation.

[0047] Example 1

[0048] like Figure 1 As shown, a production process for a glass fiber production equipment, in this embodiment based on a glass fiber production equipment of Embodiment 2, includes the following steps:

[0049] S1: First, four sets of winding units 2 are installed on the rotating frame 3. At the start of production, the glass fiber in the melting box is guided to the end of the winding drum 23 of the first set of winding units 2 below the pressure frame 5, and the initial glass fiber is positioned by the pressing mechanism. Then, the winding motor 21 drives the rotating shaft 22 to rotate to wind the glass fiber. During winding, the pressure block 247 also rotates with the rotating shaft 22. The guide machine 1 moves along the axial direction of the rotating shaft 22 to the middle of the winding drum 23, and winds the glass fiber evenly to the middle of the winding drum 23 in the linear reciprocating motion of the guide machine 1.

[0050] S2: After the first winding unit 2 completes winding, the drive motor 7 drives the rotating frame 3 to rotate 90° away from the guide machine 1, so that the next winding unit 2 rotates to below the pressure frame 5. At the same time, the guide machine 1 drives the corresponding strand of glass fiber to move to the end of each winding drum 23. Then, the pressure cylinder presses down again to drive the pressing mechanism to complete the cutting and positioning of the first segment of the initial glass fiber. The specific cutting and positioning steps are as follows:

[0051] The cylinder activation causes the mounting rod to press down towards the winding unit 2. When the pressure rod 9 contacts the inclined block 245, the pressure block 247 moves towards the end of the winding drum 23 under the drive of the inclined block 245. When the pressure block 247 presses against the glass fiber at the end of the winding drum 23, the cutter 8 also contacts the end of the winding drum 23, thereby achieving the slitting of the glass fiber. The pressure block 247 presses against the first segment of the slitting glass fiber to be wound up, while the positioning spring assembly... The pressure block 247 is released from the inclined block 245 and pressed against one side of the inclined block 245, so that the pressure block 247 is kept pressing against the end of the winding drum 23. Then, the pressure cylinder drives the mounting rod to move up away from the winding unit 2, and the winding motor 21 drives the rotating shaft 22 to rotate to wind the glass fiber. After winding, the rotating frame 3 rotates 90° away from the guide machine 1 again, so that the next winding unit 2 rotates to the bottom of the pressure frame 5, and the winding operation is repeated.

[0052] S3: When the winding unit 2 finishes winding and rotates to the bottom of the rotating frame 3, the support frame set below the rotating frame 3 supports the winding drum 23. Then, the screw motor is started to drive the screw to rotate, so that the two sets of positioning frames move away from each other. In the away movement, the two sets of positioning frames disengage from the short shaft, and the drive end of the winding motor 21 disengages from the rectangular transmission block. Then, the conveyor used to drive the support frame to move is started to move the winding unit 2 carrying the finished winding away. At the same time, the next empty winding unit 2 is supported by the support frame and moved to the bottom of the rotating frame 3. Then, the screw motor is started again to make the screw rotate in the opposite direction, and the two sets of positioning frames move towards each other. In the opposite movement, the two sets of positioning frames are fitted into the short shaft until they abut against the end of the rotating shaft 22. At the same time, the rectangular transmission block at one end of the short shaft is also inserted and installed into the rectangular transmission groove at the drive end of the winding motor 21. Then, wait for the rotating frame 3 to rotate again so that the installed winding unit 2 moves to the bottom of the pressure frame 5 for winding.

A production process for a glass fiber production equipment, based on the glass fiber production equipment of claim 3, characterized in that, Includes the following steps: S1: First, four sets of winding units (2) are installed on the rotating frame (3). At the beginning of production, the glass fiber in the melting box is guided to the end of the winding drum (23) of the first set of winding units (2) below the pressure frame (5). The initial glass fiber is positioned by the pressing mechanism. Then, the winding motor (21) drives the rotating shaft (22) to rotate to wind the glass fiber. During winding, the pressure block (247) also rotates with the rotating shaft (22). The guide machine (1) moves along the axial direction of the rotating shaft (22) to the middle of the winding drum (23). In the linear reciprocating motion of the guide machine (1), the glass fiber is evenly wound to the middle of the winding drum (23). S2: After the first winding unit (2) finishes winding, the drive motor (7) drives the rotating frame (3) to rotate 90° away from the guide machine (1), so that the next winding unit (2) rotates to the bottom of the pressure frame (5). At the same time, the guide machine (1) drives the corresponding strand of glass fiber to move to the end of each winding drum (23). Then, the pressure cylinder presses down again to drive the pressing mechanism to complete the cutting and positioning of the first segment of the initial glass fiber. The specific cutting and positioning steps are as follows: The cylinder is activated, causing the mounting rod to press down and approach the winding unit (2). When the pressure rod (9) contacts the inclined block (245), the pressure block (247) moves towards the end of the winding drum (23) under the drive of the inclined block (245). When the pressure block (247) presses against the glass fiber at the end of the winding drum (23), the cutter (8) also contacts the end of the winding drum (23), thereby achieving the slitting of the glass fiber. The pressure block (247) presses against the first section of the slitting glass fiber to be wound, while the positioning spring pressure group... It comes out from the inclined block two (245) and presses against one side of the inclined block two (245), so that the pressure block (247) keeps pressing against the end of the winding drum (23). Then, the pressure cylinder drives the mounting rod to move up away from the winding unit (2), and the winding motor (21) drives the rotating shaft (22) to rotate to wind the glass fiber. After winding, the rotating frame (3) rotates 90° away from the guide machine (1) again, so that the next winding unit (2) rotates to the bottom of the pressure frame (5) and the winding operation is repeated. S3: When the winding unit (2) finishes winding and rotates to the bottom of the rotating frame (3), the support frame set below the rotating frame (3) supports the winding drum (23). Then, the lead screw motor is started to drive the lead screw to rotate, so that the two sets of positioning frames move away from each other. During the away movement, the two sets of positioning frames disengage from the short shaft, and the drive end of the winding motor (21) disengages from the rectangular transmission block. Then, the conveyor used to drive the support frame to move is started to move the winding unit (2) carrying the finished winding away from the next winding unit. The empty winding unit (2) is supported by the support frame and moved to the bottom of the rotating frame (3). Then the screw motor is started to make the screw rotate in the opposite direction.
