Description

Technical Field

[0001] This invention belongs to the field of fastener surface treatment technology and relates to a wire coating system. Background Technology

[0002] Wire coating equipment is a core piece of equipment in the production and application of titanium alloy fasteners. The quality of the coating it produces directly determines the surface protection performance and service life of the titanium alloy fasteners. Currently, mainstream titanium alloy fastener coating processes generally employ spraying and tubular heating methods for coating preparation. Through methods such as immersion, spraying, or roller coating, the coating liquid is first uniformly adhered to the surface of the titanium alloy wire, and then heat-curing treatment is performed to form a dense and stable coating on the wire surface, ultimately achieving the purpose of surface protection and performance enhancement of the fasteners.

[0003] However, this type of process has significant technical drawbacks: on the one hand, the uneven particle size distribution of the atomized particles during spraying can easily lead to fluctuations in the coating thickness on the wire surface, forming localized thick or thin film areas; on the other hand, the tubular heating furnace cures the wire coating from the outside in, which can easily cause insufficient adhesion between the coating and the wire substrate, resulting in problems such as coating peeling and cracking during subsequent processing or service. These defects not only seriously affect the efficiency of the wire upsetting and drawing process at the rear end, but also directly reduce the product qualification rate and reliability of titanium alloy fasteners.

[0004] Therefore, in order to fundamentally improve the coating quality of filaments and enhance the uniformity, density, and adhesion of the coating on the filament surface, this application presents a filament coating system. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and propose a wire coating system, which is used to achieve surface coating treatment of wire and improve the efficiency of back-end upsetting and drawing of wire.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention discloses a filament coating system, including a coating chamber with a feeding port and a discharging port on two opposite side walls. The coating chamber is equipped with a clamping and feeding mechanism. After passing through the clamping and feeding mechanism, the filament sequentially passes through a bending mechanism, a filament coating mechanism, a curing mechanism, and a tension adjustment mechanism, and finally exits from the discharging port. The filament coating path formed by the bending mechanism, the filament coating mechanism, the curing mechanism, and the tension adjustment mechanism is circular. The filament coating mechanism includes a primary coating component and a secondary coating component.

[0007] Furthermore, the clamping and feeding mechanism includes a feeding fixing seat, a transmission gear assembly is provided between the first panel and the second panel of the feeding fixing seat, a transmission wheel assembly fixedly connected to the transmission gear is provided on the outer side of the first panel, and a power system fixedly connected to the transmission gear is provided on the outer side of the second panel.

[0008] Furthermore, the transmission wheel assembly includes several second transmission wheels fixedly connected to the feeding fixed seat, each second transmission wheel is provided with a sliding seat below it, the sliding seat is provided with several third transmission wheels, and the sliding seat is energized to the piston rod of the cylinder; the cylinder drives the sliding seat to move the third transmission wheels closer to or away from the second transmission wheels.

[0009] Furthermore, the bending mechanism includes a bending bracket fixedly connected to the coating chamber. Support wheels and a lifting module are sequentially arranged on the vertical surface of the bending bracket along the wire coating path. A first drive motor is fixedly connected above the bending bracket. A gearbox is provided at the output end of the first drive motor. A power distribution system is provided inside the gearbox. A plurality of first transmission wheels are connected to the gear shaft of the power distribution system. The support wheel is located directly below the plurality of first transmission wheels.

[0010] Furthermore, the primary coating assembly and the secondary coating assembly are respectively placed in corresponding constant temperature spaces, and both the primary coating assembly and the secondary coating assembly include an induction coil heater and a spraying device. The curvature of each induction coil heater is consistent with the bending curvature of the filament, and the filament passes through the induction coil heater and the spraying device in sequence during the coating process.

[0011] Furthermore, the spraying device includes a stirring system and a first material tank. The first material tank includes a detachably connected seepage wall with a plurality of seepage holes. The bottom of the first material tank is provided with a through hole for the wire to pass through, and the upper and lower ends of its outer wall are respectively connected to a first guide pipe and a second guide pipe. The other ends of the first guide pipe and the second guide pipe are both connected to the stirring system.

[0012] Furthermore, the stirring system includes a second material tank, inside which a stirring frame is provided, and the upper end of the stirring frame shaft is connected to a hollow rotating platform; a funnel is provided on the hollow rotating platform, and the funnel is located below the bottom through hole of the first material tank.

[0013] Furthermore, the curing mechanism uses a tubular heater as the core heating unit, and the curvature of the tubular heater is consistent with the bending curvature of the filament.

[0014] Furthermore, the tension adjustment mechanism includes a mounting plate, on which a tension swing arm is rotatably connected. The first swing end of the tension swing arm is provided with a pressure wheel that contacts the wire, and the second swing end of the tension swing arm is provided with a wire pull sensor.

[0015] Furthermore, the filament coating route is provided with several tracks, and the bearing surface of the tracks adopts a grid roller structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects: First, this invention achieves power delivery of the material head through a clamping and feeding mechanism. When the filament to be coated just enters the coating system, the second and third transmission wheels of the clamping and feeding mechanism actively grab and drive the filament head, helping the filament overcome equipment friction, its own weight, and initial inertia, so that it smoothly enters the circumferential filament coating system composed of the bending mechanism, filament coating mechanism, curing mechanism, and tension adjustment mechanism. The clamping and feeding mechanism can effectively avoid the problems of filament head jamming and deviation, solve the pain point that the filament is difficult to enter the track due to its soft and droopy head, ensure the continuous start of the processing flow, and ensure the consistent speed of the head, middle, and tail of the filament during the coating process, thereby achieving the consistency of quality control of the head, middle, and tail of the filament after coating.

[0017] Secondly, this invention innovatively adds a support wheel structure before bending the wire, ensuring that the centerline dimension of the wire remains consistent during bending, before bending, and after bending, avoiding unevenness in the wire and significantly improving the bending dimensional accuracy. At the same time, the bending mechanism uses a gearbox as the transmission method to control the bending feeding and support speed, so that there is no relative speed and no slippage of the wire. This not only improves the pre-bending status of the wire before bending but also enhances the stability of the wire bending process.

[0018] Third, the filament coating mechanism of the present invention, by introducing a hollow rotating platform, precisely realizes the controllable adjustment function of the stirring speed of the coating liquid, so that the coating liquid is fully mixed and homogenized throughout the entire process of filament coating, fundamentally ensuring that the process state and mixing effect of the coating liquid are highly consistent. In addition, the inner wall of the first material tank is set as a detachable seepage wall, which facilitates cleaning after coating and avoids the coating liquid from clogging the first material tank and affecting the subsequent coating effect. On the other hand, the seepage holes on the seepage wall are adapted to the precision coating requirements of filament, which can enable the coating to be uniformly adhered in the axial direction of the filament, ensuring consistent coating quality throughout the entire filament.

[0019] Fourth, by setting up a first induction coil heater and a second induction coil heater, the present invention achieves drying and preliminary curing of the coating on the surface of the wire, ensuring that the coating is stably attached to the surface of the wire; then, the coating is fully cured from the outside to the inside by a tubular heater, which effectively improves the bonding strength between the coating and the wire substrate and avoids problems such as coating peeling and cracking during subsequent processing or service.

[0024] Exemplary embodiments will now be described in detail. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples consistent with some aspects of the invention as detailed in the appended claims.

[0025] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Example

[0026] Firstly, such as Figure 1 As shown, the present invention provides a filament coating system, including a coating chamber 1, wherein a feeding port and a discharging port are respectively provided on two opposite side walls of the coating chamber 1; a clamping feeding mechanism 2 is provided inside the coating chamber 1, and the filament passes through the clamping feeding mechanism 2, and then sequentially passes through a bending mechanism 4, a filament coating mechanism, a curing mechanism 10 and a tension adjustment mechanism 3, and finally exits from the discharging port; the filament coating path formed by the bending mechanism 4, the filament coating mechanism, the curing mechanism 10 and the tension adjustment mechanism 3 is circular; the filament coating mechanism includes a primary coating component and a secondary coating component.

[0027] Specifically, the various mechanisms cooperate with each other to keep the wire bent at a fixed curvature and smoothly transfer it to the next processing step through the discharge port.

[0028] Furthermore, such as Figure 6 As shown, the clamping and feeding mechanism 2 includes a feeding fixing seat 22. A transmission gear assembly 25 is provided between the first panel and the second panel of the feeding fixing seat 22. A transmission wheel assembly fixedly connected to the transmission gear assembly 25 is provided on the outer side of the first panel. A power system 26 fixedly connected to the transmission gear assembly 25 is provided on the outer side of the second panel.

[0029] Specifically, the power system 26 provides a suitable speed for the system through a "second drive motor + reducer" method, and the speed can be adjusted according to actual production needs.

[0030] More specifically, the output end of the power system 26 is connected to a transmission gear assembly 25, which connects the second transmission wheel 23 and the third transmission wheel 24 to realize dual-wheel transmission. By utilizing the cooperation of the two wheels, the wire clamping and transmission function is realized.

[0031] Furthermore, the transmission wheel assembly includes several second transmission wheels 23 fixedly connected to the feeding fixed seat 22. Each second transmission wheel 23 is provided with a sliding seat below it. Several third transmission wheels 24 are provided on the sliding seat, and the sliding seat is connected to the piston rod of the cylinder. The cylinder drives the sliding seat to move the third transmission wheels 24 closer to or away from the second transmission wheels 23.

[0032] Specifically, the cylinder is driven by an electric motor.

[0033] Specifically, the distance between the second transmission wheel 23 and the third transmission wheel 24 is determined according to the diameter of the filament to be coated, so as to ensure the clamping force of the transmission wheel on the filament; at the same time, the clamping action of each transmission wheel on the filament forms a stable friction force, which drives the filament to move forward or backward. By adjusting the conveying speed of the filament in real time, the problem of asynchronous feeding of the head and tail of the filament during the coating process is solved.

[0034] Furthermore, such as Figure 3 , 4 As shown in Figure 5, the bending mechanism 4 includes a bending bracket 34 fixedly connected to the coating chamber 1. Support wheels 19 and lifting modules 21 are sequentially arranged on the vertical surface of the bending bracket 34 along the wire coating path. A first drive motor 15 is fixedly connected above the bending bracket 34. A gearbox 16 is provided at the output end of the first drive motor 15. A power distribution system is provided inside the gearbox 16. A plurality of first transmission wheels 17 are connected to the gear shaft of the power distribution system. The support wheels 19 are located directly below the plurality of first transmission wheels 17.

[0035] Specifically, the power distribution system is used for both silk material transportation and silk material bending rate adjustment. The power for silk material transportation is provided by the first drive motor 15, the output end of which is connected to the gearbox 16. The gearbox 16 is equipped with a set of meshing gears. Based on the principle of consistent linear velocity during gear meshing, the rotational speed of the output gear shaft of the gearbox 16 is kept constant. The first transmission wheel 17 and the support wheel 19, which are fixedly connected to the gear shaft, form a clamping structure for the silk material. Driven by friction, the silk material moves forward smoothly at a constant speed as the first transmission wheel 17 rotates.

[0036] Specifically, the lifting module 21 includes a lead screw slide and a third drive motor. The lifting module 21 uses the third drive motor to drive the slide to move up and down to achieve precise positioning of the bending wheel 18, ensuring accurate bending of the wire material, thereby achieving controllable winding diameter of the wire material, and enabling the wire material to be wound up according to the required bending rate during the processing.

[0037] Specifically, a mounting bracket is provided below the support wheel 19, and a valve stem is rotatably connected to the mounting surface of the mounting bracket; a handwheel is fixed at the end of the valve stem away from the mounting bracket; the valve stem and the mounting bracket adopt a threaded transmission structure, and by rotating the handwheel to drive the valve stem to rotate, the support wheel 19 can be driven to rise and fall in the vertical direction, so that the distance between the support wheel 19 and the first transmission wheel 17 matches the diameter of the coated filament.

[0038] More specifically, each of the first transmission wheels 17 is a drive wheel, used to drive the filament forward during the coating process.

[0039] Furthermore, the primary coating assembly and the secondary coating assembly are respectively placed in corresponding constant temperature spaces 35, and both the primary coating assembly and the secondary coating assembly include an induction coil heater and a spraying device, such as... Figure 8 As shown, the curvature of each of the induction coil heaters is consistent with the bending rate of the wire, and the wire passes through the induction coil heater and the spraying device in sequence during the coating process.

[0040] Specifically, the first induction coil heater 6 in the primary coating assembly is used to preheat the filament so that the coating liquid adheres tightly to the surface of the filament; the secondary coating assembly is used to achieve uniformity and smoothness of the coating on the surface of the filament, ensuring that the coating quality meets the standards.

[0041] Specifically, in the filament coating route, temperature sensors are provided at the feed end and discharge end of the first induction coil heater 6, as well as at the discharge end of the second induction coil heater 33 in the secondary coating assembly; the temperature sensors are used to monitor the temperature during the filament coating process, and thus adjust the working temperature of the first induction coil heater 6, the second induction coil heater 33 and the tubular heater 10 in a timely manner.

[0042] More specifically, the power of the first induction coil heater 6 and the second induction coil heater 33 can be adjusted according to the speed of the filament to ensure that the coating on the filament dries and cures, and is stably attached to the surface of the filament.

[0043] Specifically, each of the induction coil heaters uses the principle of induction heating to heat the wire material. The temperature of the induction coil 31 is controlled by the induction power supply 30, thereby increasing the temperature of the wire material, drying and curing the coating on the surface of the wire material, thus achieving the requirements of coating thickness and adhesion reliability.

[0044] Furthermore, the spraying device includes a stirring system 9 and a first material tank 8, such as... Figure 10 As shown, the first material tank 8 includes a detachably connected seepage wall, on which a plurality of seepage holes are provided; the bottom of the first material tank 8 is provided with a through hole for the wire to pass through, and the upper and lower ends of its outer wall are respectively connected to a first guide pipe and a second guide pipe, the other ends of the first guide pipe and the second guide pipe are both connected to the stirring system 9.

[0045] Specifically, the detachable connection of the seepage wall facilitates regular cleaning of the first material tank 8 and prevents the coating liquid from clogging the seepage holes.

[0046] Specifically, the first feed pipe is used to transport the coating liquid, and the second feed pipe is used to return the remaining coating liquid in the first tank to the second tank.

[0047] Specifically, the size of the through hole is adapted to the diameter of the coating filament, and the two are in a clearance fit; in order to prevent the coating liquid from seeping out from the gap, a flexible sealing filler (including but not limited to cloth strips and gauze) is embedded in the gap, and the flexible sealing filler is used to block the seepage of the coating liquid.

[0048] More specifically, during the coating process, the filament travels upward from the through hole at the bottom of the first material tank 8 to the top of the first material tank 8.

[0049] Furthermore, such as Figure 2 As shown, the stirring system 9 includes a second material tank 14, and a stirring frame 13 is provided inside the second material tank 14. The upper end of the stirring frame shaft is connected to a hollow rotating platform 12. A funnel 11 is provided on the hollow rotating platform 12, and the funnel is located below the bottom through hole of the first material tank 8.

[0050] Specifically, the second material tank 14 is equipped with a matching coating pump. One end of the suction guide pipe of the coating pump extends into the second material tank 14, and the other end is sealed to the pump inlet. One end of the discharge guide pipe of the coating pump is sealed to the pump outlet, and the other end is connected to the first guide pipe, which is used to transport the coating liquid to the inside of the first material tank 8.

[0051] Specifically, the hollow rotating platform 12 drives the stirring rack 13 to stir in the second material tank 14 to achieve a stable and uniform coating liquid system, thereby maintaining a constant coating liquid density, avoiding coating deviations caused by local concentration differences, and ultimately achieving uniform coating thickness on the wire surface.

[0052] Specifically, the funnel 11 is used to receive a small amount of coating liquid seeping out from the bottom through hole of the first material tank 8.

[0053] Furthermore, such as Figure 9As shown, the curing mechanism 10 uses a tubular heater as the core heating unit, and the curvature of the tubular heater is consistent with the bending curvature of the filament.

[0054] Specifically, the high temperature generated by the tubular heater 10 is used to achieve rapid drying and curing of the coating surface, improve the surface smoothness and coating quality, and shorten the process cycle and improve coating production efficiency.

[0055] Furthermore, such as Figure 7 As shown, the tension adjustment mechanism 3 includes a mounting plate 32, on which a tension swing rod 28 is rotatably connected. The first swing end of the tension swing rod 28 is provided with a pressure wheel 27 that contacts the wire, and the second swing end of the tension swing rod 28 is provided with a wire pull sensor 29.

[0056] Specifically, the wire pull sensor 29 can monitor the position of the pressure roller 27 in real time during the filament coating process. When the filament moves, it drives the wire pull to extend and retract. The wire pull sensor 29 converts the mechanical displacement of the pressure roller 27 into an electrical signal, calculates and outputs the actual conveying speed of the filament in real time. The PLC control system receives the actual conveying speed signal of the filament fed back by the wire pull sensor 29, compares it with the preset coating process target speed, and judges the speed deviation value. If the actual conveying speed is too fast or too slow, the PLC control system immediately sends a speed adjustment command to the power system 26. The power system 26 adjusts its own output speed parameters according to the command, and then transmits power to the second transmission wheel 23 through the transmission gear 25, thereby changing the running speed of the second transmission wheel 23 and realizing the precise matching of the filament conveying speed, coating process speed and winding speed.

[0057] Furthermore, a number of tracks 5 are provided on the filament coating route, and the bearing surface of the tracks 5 adopts a grid roller structure.

[0058] Specifically, the grid roller track can achieve the positioning function of the filament, reduce the lateral movement of the filament in the coating chamber, and improve the stability of the filament moving along the curve.

[0059] This specification also provides a working process for a wire coating system, specifically as follows: The filament to be coated is fed into the coating chamber 1 through the inlet, first passing through the clamping and feeding mechanism 2. The clamping and feeding mechanism 2 is fixed to the steel structure of the coating chamber 1 by bolts. The feeding fixing seat 22 acts as an outer frame, connecting the components of the clamping and feeding mechanism 2 and also being bolted into the coating chamber 1. When the filament reaches the clamping and feeding mechanism 2, the second drive motor in the power system 26 drives the second transmission wheel 23 to rotate. The second transmission wheel 23 drives the third transmission wheel 24, sending the filament to the bending mechanism 4.

[0060] The bending mechanism 4 is fixed to the bottom surface of the coating chamber by bolts and embedded outside the coating chamber 1. The first drive motor 15 continues to provide power for the coating and transportation of the filament. The output end of the first drive motor 15 is connected to the gearbox 16. The gearbox 16 is equipped with a set of meshing gears. Based on the principle of consistent linear velocity during gear meshing, the rotational speed of the output gear shaft of the gearbox 16 is kept constant. The first transmission wheel 17 and the support wheel 19 fixedly connected to the gear shaft form a clamping structure for the filament. Driven by friction, the filament moves forward smoothly at a constant speed with the rotation of the first transmission wheel 17. When the filament reaches the lifting module 21, the lifting module 21 uses its own third drive motor to drive the slide to move up and down to achieve precise positioning of the bending wheel 18, ensuring accurate bending of the filament specifications, thereby achieving controllable winding diameter of the filament, and enabling the filament to be wound up according to the required bending rate during processing.

[0061] Subsequently, the temperature sensor 7 is used to measure the temperature of the filament before it enters the first induction coil heater 6, and to adjust the power of the induction power supply 30 of the first induction coil heater 6 in a timely manner so that the filament is preheated before entering the first spraying process. In the first spraying process, the coating pump configured in the second material tank 14 pumps the coating liquid into the first material tank 8 through the first material guide pipe. The coating liquid is coated onto the filament through the seepage hole. The filament is dried and cured by the second induction coil heater 33 to ensure that the coating liquid is stably attached to the surface of the filament. Then the filament is sent to the next coating device for the second spraying process, and then reaches the tubular heater 10. The high temperature generated by the tubular heater 10 can realize the rapid drying and curing of the coating surface, improve the surface smoothness and coating quality of the coating layer, and at the same time shorten the process cycle and improve the coating production efficiency.

[0062] The tension adjustment mechanism 3 is fixed in the coating chamber 1 by an embedded method to ensure the stability of the filament coating process. When the coated filament passes through the tension adjustment mechanism 3, the wire pull sensor 29 can monitor the position of the pressure roller 27 in real time during the filament coating process. When the filament moves, it drives the wire pull to extend and retract. The wire pull sensor 29 converts the mechanical displacement of the pressure roller 27 into an electrical signal, calculates and outputs the actual conveying speed of the filament in real time. The PLC control system receives the actual conveying speed signal of the filament fed back by the wire pull sensor 29, compares it with the preset coating process target speed, and judges the speed deviation value. If the actual conveying speed is too fast or too slow, the PLC control system immediately sends a speed adjustment command to the power system 26. The power system 26 adjusts its own output speed parameters according to the command, and then transmits the power to the second transmission wheel 23 through the transmission gear 25, thereby changing the running speed of the second transmission wheel 23 and realizing the precise matching of the filament conveying speed, coating process speed and winding speed.

[0063] In addition, the track 5 is fixed inside the coating chamber 1 by bolts. The bearing surface of the track 5 is composed of rollers arranged in a grid pattern, which can realize the positioning function of the filament, reduce the lateral movement of the filament in the coating chamber, and improve the stability of the filament moving along the curve.
