Description
Technical Field
[0001] The invention relates to the technical field of fiber material processing, in particular to a domestic special fiber forming device for automobile clutch facings. Background Art
[0002] In the manufacturing of automotive clutch facings, specialty fibers such as core-spun yarn and composite yarn have become key raw materials due to their excellent mechanical properties, high-temperature resistance, and wear resistance. However, the current domestic molding equipment used to produce these specialty fibers has numerous structural design deficiencies, limiting improvements in product quality and production efficiency.
[0003] The pay-off frames of existing equipment mostly adopt a simple mechanical linkage structure, and different raw material rolls cannot achieve independent and precise pay-off control, which makes it difficult to accurately match the delivery ratio of core material and outer fiber, and different component fibers when preparing core-spun yarn or composite wire, and often results in uneven tension of raw materials and disordered winding; the composite molding structure of traditional devices is simple, and the core-spun yarn molding device usually lacks a linkage adjustment mechanism for the rotation speed and feed speed, resulting in uneven coating of the outer fiber, and prone to problems such as loose or tight coating and core material offset; the existing equipment does not have a monitoring mechanism, and cannot guarantee the quality status of the fiber after molding, and the fiber has obvious tension fluctuations after going through multiple processes, which can easily lead to limited tensile deformation, breakage and other quality problems that cannot be effectively improved. Summary of the Invention
[0004] The purpose of the present invention is to provide a domestic special fiber molding device for automobile clutch facings to solve the problems raised in the background technology.
[0005] To achieve the above objectives, the present invention provides the following technical solutions: a domestically produced special fiber forming device for automobile clutch facings, comprising a machine body, a support platform welded to one side of the machine body, a core-spun yarn winding assembly provided on the support platform, fiber control assemblies provided on both sides of the core-spun yarn winding assembly, a pay-off assembly provided on one side of the fiber control assembly, fiber processing assemblies provided below and above the pay-off assembly, a traction monitoring assembly provided on the side of the machine body, and a take-up assembly provided on the top of the machine body; The top surface of the support platform is fixed with a winding platform by screws, and the winding platform is provided with a hollow hole, and the hollow hole is composed of two I-shaped structures; The pay-off assembly includes a servo motor, a support plate, a bearing, a winding drum and an embedded fixing piece. The winding drum is provided with several and all are nested on the outside of the embedded fixing piece. The embedded fixing piece passes through the bearing and is connected to one end of the servo motor. The servo motor is fixed to one side of the support plate by screws. The core winding assembly includes a yarn guide ring, a yarn threading drum, a rotary disk, a winding ring and a power piece. The yarn guide ring is fixed to the bottom of the hollow hole and directly below the yarn threading tube by screws. A turntable is welded to the outside of the top of the yarn threading tube. Several winding rings are welded at equal intervals around the turntable. The traction monitoring component includes a high-definition industrial camera, a laser caliper and a traction ring.
[0006] The servo motor drives the fixed shaft to rotate in the bearing, thereby driving the winding drum to rotate, releasing the steel wire and aramid fiber at a specific speed for rotary coating operation. During coating, the yarn feeding drum drives the winding ring on the rotary disk to rotate with the steel wire in the yarn feeding drum as the center, so that the aramid fiber passing through the winding ring wraps around the steel wire. The controller adjusts the rotary coating speed and the aramid fiber feeding speed by controlling the speed of the power motor and the servo motor, so that the outer layer of fiber is evenly wrapped on the surface of the steel wire.
[0007] High-definition industrial cameras and laser diameter gauges are used to continuously monitor the surface condition and diameter size of the core-spun yarn. If core material offset or diameter deviation exceeding the threshold is detected, the controller immediately adjusts the covering speed and fiber feed speed to improve product quality.
[0008] Furthermore, the yarn threading tube is a hollow structure, the traction ring is fixed to the inclined surface of the machine body at equal intervals by screws, the high-definition industrial camera is arranged on one side of the traction ring, the laser diameter gauge is arranged between the traction rings, and a controller is fixed to one side of the machine body by screws.
[0009] Furthermore, the interlocking fixing part includes a fixed shaft, a limit plate and a limit head. The limit plates are welded on both sides of the fixed shaft and the limit head. One end of the fixed shaft is connected to the servo motor through a coupling, and the other end is interlocked with the limit head and rotates together. The outer side of the fixed shaft is nested in the winding cylinder and slides together. The support plate is fixed to the top surface of the support platform by bolts, and the servo motor is electrically connected to the controller.
[0010] When installing the winding drum, rotate the limit head to align the limit plates on both sides with the limit plates on both sides of the fixed shaft horizontally, so that the winding drum is embedded in the limit plates, and then continue to twist the limit head to clamp the winding drum on the fixed shaft. Furthermore, the power component includes a power motor, a main bevel gear and a secondary bevel gear. The power motor is fixed to the top surface of the hollow hole by screws. One end of the power motor is connected to the main bevel gear. The main bevel gear engages with the secondary bevel gear and rotates in conjunction. The secondary bevel gear is welded to the bottom end of the yarn threading tube, and the power motor is electrically connected to the controller.
[0011] During wrapping, the power motor drives the main bevel gear to rotate, and then drives the yarn threading bobbin to rotate through the secondary bevel gear.
[0012] Furthermore, the fiber control component includes a lower roller, an upper roller, a pressure plate, a control motor, a rotating shaft, a torsion spring and a tension sensor. The pressure plate is welded on the top of the upper roller, and the pressure plate is fixed to one side of the rotating shaft by screws. The two ends of the rotating shaft are engaged with one side of the machine body and rotate together, and the controller is electrically connected to the control motor.
[0013] Furthermore, a torsion spring is welded between both ends of the rotating shaft and the machine body, the torsion spring is nested on the outside of the rotating shaft, one end of the lower roller is connected to the control motor, and the tension sensor is arranged on one side of the lower roller.
[0014] When pulling the aramid fiber through the fiber control component, the pressure plate needs to be moved upward. The pressure plate drives the upper roller to separate from the lower roller. At the same time, the rotating shaft rotates and drives the torsion spring to accumulate elastic potential energy. Then the pressure plate is released. Under the rebound of the torsion spring, the aramid fiber is pressed between the upper roller and the lower roller and rotates with the roller. The controller controls the speed of the motor to create a speed difference between different lower rollers, thereby controlling the winding diameter of the fiber. The fiber tension is monitored in real time through the tension sensor and fed back to the controller. The controller controls the tension by adjusting the servo motor speed to stabilize it within the set range.
[0015] Furthermore, the fiber processing component includes a temperature controller, an infrared radiation heating tube, a wind tube and a fan. The temperature controller is electrically connected to the infrared radiation heating tube. The infrared radiation heating tube is arranged directly below the winding drum. The wind tube is fixed to one side of the machine body by screws and faces the traction ring. The fan is fixed to the inside of the wind tube by screws.
[0016] The heating temperature is set to 60°C through the thermostat. The thermostat controls the infrared radiation heating tube to heat up and radiate energy to the core material roll and outer fiber roll directly above in the form of infrared electromagnetic waves, so that the temperature rises to 60°C. The preheating design can reduce the brittleness of the fiber in subsequent processing and reduce the risk of breakage. After the fiber is formed, the controller starts the fan on one side of the traction ring. The air flow passes through the wind tube to cool the core-spun yarn, so that the fiber is quickly solidified and the fiber state is stabilized.
[0017] Furthermore, the wire-taking assembly includes a rotating motor, one end of which is connected to a main gear, the main gear engages with a sub-gear and rotates together, the sub-gear is welded on a central shaft, one end of the central shaft engages with a back plate and rotates together, and a spring is welded on the outside of the other end, a clamping plate is provided on one side of the spring, the clamping plate engages with the wire-taking reel and slides together, one end of the wire-taking reel abuts against the spring and the other end abuts against the back plate and rotates together, and the rotating motor is electrically connected to the controller.
[0018] When winding, the rotating motor drives the main gear to rotate, and the main gear drives the center shaft to rotate on the back plate through the sub-gear, and then drives the take-up drum to rotate and rewind through the clamping plate on the center shaft. When disassembling the take-up drum, you only need to use the take-up drum compression spring to make one end of the take-up drum separate from the limit shaft of the back plate.
[0019] Furthermore, composite wire forming components are additionally provided on both sides of the machine body, and the composite wire forming components include a vortex spindle, a twister, a yarn guide, a motor, an L-shaped plate and an optical tomography scanner.
[0020] Furthermore, the vortex spindle is arranged between the traction rings, the L-shaped plate is fixed to the back side of the machine body by bolts, the motor is fixed to the bottom end of the L-shaped plate by screws, one end of the motor is welded to the bottom end of the twister, the yarn guide is arranged on one side of the twister, the motor is electrically connected to the controller, and the optical tomography scanner is fixed above the twister by screws.
[0021] After the equipment is started, the raw material supply conveys glass fiber bundles and aramid fiber bundles in proportion to the vortex spindles, and uses air flow traction to initially compound. The compounded fiber bundles enter the twister, and the motor drives the twister to rotate to perform secondary twisting of the fiber bundles to enhance the binding force of the fiber bundles. The controller controls the speed of the motor and then controls the twist of the twister. The tension sensor monitors and adjusts the tension of each fiber bundle in real time to ensure the stability of the compounding process. The optical tomography scanner detects in real time whether there is stratification inside the composite line and monitors the diameter size through the laser diameter gauge. Once an abnormality is found, the controller automatically adjusts the speed of the twister and the feeding speed of each servo motor.
[0022] Compared with the prior art, the present invention provides a domestic special fiber forming device for automobile clutch facings, which has the following beneficial effects: 1. This domestically produced specialty fiber molding equipment uses a servo motor to precisely control the raw material supply ratio and composite molding parameters, achieving high-precision structural design of core-spun yarns and composite lines.

The traction monitoring component 7 includes a high-definition industrial camera 71, a laser diameter gauge 72 and a traction ring 73.
[0028] The servo motor 51 drives the fixed shaft 55 to rotate in the bearing 53, thereby driving the winding drum 54 to rotate, releasing the steel wire and aramid fiber at a specific speed, and performing a rotary coating operation. During coating, the yarn threading drum 32 drives the winding ring 34 on the rotary disk 33 to rotate with the steel wire in the yarn threading drum 32 as the center, thereby making the aramid fiber passing through the winding ring 34 wrap around the steel wire. The controller 11 adjusts the rotary coating speed and the aramid fiber feeding speed by controlling the speed of the power motor 35 and the servo motor 51, so that the outer layer of fiber is evenly wound on the surface of the steel wire.
[0029] The surface condition and diameter size of the core-spun yarn are continuously monitored through a high-definition industrial camera 71 and a laser diameter gauge 72. If the core material offset or diameter deviation exceeds the threshold, the controller 11 immediately adjusts the covering speed and fiber feeding speed to improve product quality.
[0030] Furthermore, the yarn threading tube 32 is a hollow structure, the traction ring 73 is fixed to the inclined surface of the machine body 1 at equal intervals by screws, the high-definition industrial camera 71 is arranged on one side of the traction ring 73, the laser diameter gauge 72 is arranged between the traction rings 73, and the controller 11 is fixed to one side of the machine body 1 by screws.
[0031] Furthermore, the interlocking fixing part includes a fixed shaft 55, a limit plate 56 and a limit head 57. The limit plates 56 are welded on both sides of the fixed shaft 55 and the limit head 57. One end of the fixed shaft 55 is connected to the servo motor 51 through a coupling, and the other end is interlocked with the limit head 57 and rotates together. The outer side of the fixed shaft 55 is nested in the winding tube 54 and slides together. The support plate 52 is fixed to the top surface of the support platform 2 by bolts, and the servo motor 51 is electrically connected to the controller 11.
[0032] When installing the winding drum 54, rotate the limit head 57 so that the limit plates 56 on both sides are horizontally aligned with the limit plates 56 on both sides of the fixed shaft 55, so that the winding drum 54 is embedded in the limit plates 56, and then continue to twist the limit head 57 to clamp the winding drum 54 on the fixed shaft 55. Furthermore, the power part includes a power motor 35, a main bevel gear 36 and a secondary bevel gear 37. The power motor 35 is fixed to the top surface of the hollow hole 211 by screws. One end of the power motor 35 is connected to the main bevel gear 36. The main bevel gear 36 engages with the secondary bevel gear 37 and rotates together. The secondary bevel gear 37 is welded to the bottom end of the yarn threading tube 32, and the power motor 35 is electrically connected to the controller 11.
[0033] During wrapping, the power motor 35 drives the main bevel gear 36 to rotate, and then drives the yarn threading drum 32 to rotate through the secondary bevel gear 37.
[0034] Furthermore, the fiber control assembly 4 includes a lower roller 41, an upper roller 42, a pressure plate 43, a control motor 44, a rotating shaft 45, a torsion spring 46 and a tension sensor 47. The pressure plate 43 is welded on the top of the upper roller 42, and the pressure plate 43 is fixed to one side of the rotating shaft 45 by screws. The two ends of the rotating shaft 45 are engaged with one side of the machine body 1 and rotate together, and the controller 11 is electrically connected to the control motor 44.
[0035] Furthermore, torsion springs 46 are welded between both ends of the rotating shaft 45 and the machine body 1 , and the torsion springs 46 are nested outside the rotating shaft 45 . One end of the bottom roller 41 is connected to the control motor 44 , and a tension sensor 47 is provided on one side of the bottom roller 41 .
[0036] When pulling the aramid fiber through the fiber control component 4, the pressure plate 43 needs to be moved upward. The pressure plate 43 drives the upper roller 42 to separate from the lower roller 41. At the same time, the rotating shaft 45 rotates and drives the torsion spring 46 to accumulate elastic potential energy. Then the pressure plate 43 is released. Under the rebound of the torsion spring 46, the aramid fiber is pressed between the upper roller 42 and the lower roller 41 and rotates with the rollers. The controller 11 controls the speed of the motor 44 to create a speed difference between different lower rollers 41, thereby controlling the winding diameter of the fiber, and monitors the fiber tension in real time through the tension sensor 47, and feeds back to the controller 11. The controller 11 controls the tension by adjusting the speed of the servo motor 51 to stabilize it within the set range.

[0038] The heating temperature is set to 60°C through the temperature controller 61. The temperature controller 61 controls the infrared radiation heating tube 62 to heat up and radiate energy to the core material roll and the outer fiber roll directly above it in the form of infrared electromagnetic waves, so that the temperature is raised to 60°C. The preheating design can reduce the brittleness of the fiber in subsequent processing and reduce the risk of breakage. After the fiber is formed, the controller 11 starts the fan 64 on one side of the traction ring 73. The air flow passes through the air duct 63 to cool the core-spun yarn, so that the fiber is quickly solidified and the fiber state is stabilized.
[0039] Furthermore, the wire-taking assembly 8 includes a rotating motor 81, one end of which is connected to a main gear 82, the main gear 82 engages with a sub-gear 83 and rotates in conjunction, the sub-gear 83 is welded on a central shaft 84, one end of the central shaft 84 engages with a back plate 85 and rotates in conjunction, and a spring 86 is nested and welded on the outside of the other end, a clamping plate 87 is provided on one side of the spring 86, the clamping plate 87 engages with a wire-taking reel 88 and slides in conjunction, one end of the wire-taking reel 88 abuts against the spring 86 and the other end abuts against the back plate 85 and rotates in conjunction, and the rotating motor 81 is electrically connected to the controller 11.
[0040] During winding, the rotating motor 81 drives the main gear 82 to rotate, and the main gear 82 drives the center shaft 84 to rotate on the back plate 85 through the sub-gear 83, and then drives the wire take-up reel 88 to rotate and rewind through the clamping plate 87 on the center shaft 84. When disassembling the wire take-up reel 88, it is only necessary to use the wire take-up reel 88 compression spring 86 to make one end of the wire take-up reel 88 detach from the limit shaft of the back plate 85. Example 2
[0041] See also Figure 6 as well as Figure 8 The difference between Example 2 and Example 1 is that a composite wire forming assembly 9 is additionally provided on both sides of the machine body 1, and the composite wire forming assembly 9 includes a vortex spindle 91, a twister 92, a yarn guide 93, a motor 94, an L-shaped plate 95 and an optical tomography scanner 96.
[0042] Furthermore, the vortex spindle 91 is arranged between the traction rings 73, the L-shaped plate 95 is fixed to the back side of the machine body 1 by bolts, the motor 94 is fixed to the bottom end of the L-shaped plate 95 by screws, one end of the motor 94 is welded to the bottom end of the twister 92, the yarn guide 93 is arranged on one side of the twister 92, the motor 94 is electrically connected to the controller 11, and the optical tomography scanner 96 is fixed above the twister 92 by screws.
[0043] After the equipment is started, the raw material supply transports the glass fiber bundle and the aramid fiber bundle to the vortex spindle 91 in proportion, and uses air flow traction to initially compound. The compounded fiber bundle enters the twister 92, and the motor 94 drives the twister 92 to rotate to perform secondary twisting of the fiber bundle to enhance the binding force of the fiber bundle. The controller 11 controls the speed of the motor 94, and then controls the twist of the twister 92. The tension sensor 47 monitors and adjusts the tension of each fiber bundle in real time to ensure the stability of the compounding process. The optical tomography scanner 96 detects in real time whether there is stratification inside the composite line and monitors the diameter size through the laser diameter gauge 72. Once an abnormality is found, the controller 11 automatically adjusts the speed of the twister 92 and the feeding speed of each servo motor 51.
[0044] The specific usage and function of this embodiment are as follows: When the device is used to produce core-spun yarn fibers, the production parameters of the core-spun yarn, such as core-diameter ratio, twist, target diameter, fiber tension, etc., are first input through the controller 11, and then the winding drum 54 wound with 0.3mm high-strength steel wire is used as the core material roll, and the winding drum 54 wound with aramid fiber is used as the outer fiber roll. The core material roll is arranged between the outer fiber rolls. During installation, the limit head 57 is rotated to align the limit plates 56 on both sides with the limit plates 56 on both sides of the fixed shaft 55 horizontally, so that the winding drum 54 is embedded in the limit plates 56, and then the limit head 57 is continued to be twisted to clamp the winding drum 54 on the fixed shaft 55, and the temperature controller 61 is turned on. The heating temperature is set to 60°C through the temperature controller 61. The temperature controller 61 controls the infrared radiation heating tube 62 to heat up and radiate energy to the core material roll and the outer fiber roll directly above in the form of infrared electromagnetic waves, so that they are heated to 60°C. The preheating design can reduce the brittleness of the fiber in subsequent processing and reduce the risk of breakage. Then the traction wire passes through the yarn guide ring 31, the yarn threading drum 32, the traction ring 73 and is finally fixed on the take-up drum 88, and the aramid fiber passes through the yarn guide ring 31, the tension sensor 47, between the upper roller 42 and the lower roller 41, the winding ring 34, the traction ring 73 and is finally fixed on the take-up drum 88. Then the equipment is started to start the core-spun yarn forming operation. When the aramid fiber is pulled through the fiber control component 4, the pressure plate 43 needs to be moved upward, and the pressure plate 43 drives the upper roller 42 to separate from the lower roller 41. At the same time, The rotating shaft 45 rotates and drives the torsion spring 46 to accumulate elastic potential energy. Then, the pressure plate 43 is released. Under the rebound of the torsion spring 46, the aramid fiber is pressed between the upper roller 42 and the lower roller 41 and rotates in conjunction with the rollers. The controller 11 controls the speed of the motor 44 to create a speed difference between different lower rollers 41, thereby controlling the winding diameter of the fiber. The tension sensor 47 monitors the fiber tension in real time and feeds it back to the controller 11. The controller 11 adjusts the speed of the servo motor 51 to keep the tension stable within the set range. The servo motor 51 drives the fixed shaft 55 to rotate in the bearing 53, thereby driving the winding drum 54 to rotate, releasing the steel wire and aramid fiber at a specific speed to perform a rotary coating operation. During coating, the power motor 35 drives the main bevel gear 36 to rotate, and then drives the yarn threading drum 32 to rotate through the secondary bevel gear 37. The yarn threading drum 32 drives the winding ring 34 on the rotary disk 33 to rotate around the steel wire in the yarn threading drum 32, thereby causing the aramid fiber passing through the winding ring 34 to wrap around the steel wire. The controller 11 adjusts the rotary coating speed and the aramid fiber feeding speed by controlling the rotation speed of the power motor 35 and the servo motor 51, so that the outer layer of fiber is evenly wound on the surface of the steel wire. The formed core-spun yarn then passes through the traction ring 73, and the controller 11 starts the fan 64 on one side of the traction ring 73. The airflow passes through the air duct 63 to cool the core-spun yarn, causing the fibers to solidify quickly and stabilize the fiber state. The core-spun yarn then passes through the traction monitoring component 7, and the surface state and diameter size of the core-spun yarn are continuously monitored by the high-definition industrial camera 71 and the laser diameter gauge 72. If the core material offset or diameter deviation exceeds the threshold, the controller 11 immediately adjusts the covering speed and fiber feeding speed to improve product quality. Finally, the wire is wound into a finished product by the take-up drum 88. During winding, the rotating motor 81 drives the main gear 82 to rotate, and the main gear 82 drives the central shaft 84 to rotate on the back plate 85 through the sub-gear 83, and then drives the take-up drum 88 to rotate and rewind through the clamping plate 87 on the central shaft 84. When removing the take-up drum 88, it is only necessary to use the take-up drum 88 to compress the spring 86 to make one end of the take-up drum 88 separate from the limit shaft of the back plate 85. When using this equipment to produce composite fiber, composite wire forming components 9 are first added to both sides of the machine body 1. Then, several winding drums 54 wrapped with glass fiber and aramid fiber are installed. The fibers are pulled through the guide yarn 31, tension sensor 47, pulling ring 73, vortex spindle 91, yarn guide 93 and twister 92 in sequence. After the equipment is started, the raw material supply delivers the glass fiber bundle and aramid fiber bundle in proportion to the vortex spindle 91. The air flow is used to pull the initial composite fiber bundle. The composite fiber bundle enters the twister 92. The motor 94 drives the twister 92 to rotate and perform a secondary twist on the fiber bundle to enhance the binding force of the fiber bundle. The controller 11 controls the speed of the motor 94, thereby controlling the twist of the twister 92. The tension sensor 47 monitors and adjusts the tension of each fiber bundle in real time to ensure a stable composite process.
