Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding wire production technology, specifically to a welding wire brushing machine. Background Technology
[0002] During the production of welding wire, contaminants adhering to the surface of the welding wire can negatively impact its quality. Foreign matter such as metal powder, grease, and flux produced during drawing or forging processes adheres to the welding wire, affecting not only the product's appearance but also easily clogging the welding torch nozzle during welding. This leads to poor wire feeding and affects the conductivity of the contact tip, resulting in unstable welding effects. In addition, foreign matter on the welding wire surface can significantly reduce the service life of the welding torch wire guide tube and contact tip. Furthermore, welding wire has a short storage time and is prone to oxidation.
[0003] In response to the above problems, production staff have taken several measures, mainly using the following two methods:
[0004] (1) Use cotton cloth, sponge, wire cleaning cloth and other items that can clean the welding wire to clean the welding wire. However, this method has the problem that the contaminants on the welding wire will quickly accumulate on the cotton cloth and other cleaning items, and the cleaning effect of the cotton cloth will decrease rapidly. In the end, the cotton cloth itself will become a source of contamination, which will reduce the surface quality of the welding wire.
[0005] (2) Concentrated dust extraction in processes and areas prone to dust generation during welding wire production can reduce the source of contaminants. While this method can reduce surface contaminants on the welding wire in the short term, it cannot directly remove them. Furthermore, it only reduces the accumulation time of contaminants, as contaminant accumulation is unavoidable. When contaminants accumulate on guide rollers, wire pressure bearings, and other parts, they will still adhere to the welding wire, reducing its quality. However, none of these methods can solve this problem once and for all. Utility Model Content
[0006] The purpose of this invention is to provide a wire brushing machine to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides a wire grating machine, including a wire feeding and take-up system, a tension control system, an oil immersion system, a cleaning system, and a safety system. The wire feeding and take-up system includes a wire feeding device and a wire taking-up device. The wire feeding device includes a synchronous pulley, a wire feeding shaft for holding a cotton thread roll, and a first drive device for driving the wire feeding shaft to rotate. The cotton thread roll is formed by winding cotton thread. The wire taking-up device includes a take-up wheel, a second drive device for driving the take-up wheel to rotate, a wire pressing device, and a waste wire hopper. The wire pressing device is located on one side of the take-up wheel, and the waste wire hopper is located below the take-up wheel. The tension control system includes a wire rail, a swivel wheel, and an analog sensor located below the wire feeding device. The swivel wheel is mounted on the wire rail, and the analog sensor is used to detect the specific position of the swivel wheel within its stroke range. The oil immersion system is located above one side of the swivel wheel. The cleaning system includes two spaced-apart guide wheel groups. The safety system includes a wire feeding and take-up device. The system includes an emergency thread-cutting device, a ratchet mechanism, and a take-up thread-cutting device. The emergency thread-cutting device is located between the pay-off shaft and the spinning wheel, and is used to cut the thread when the analog sensor detects that the spinning wheel is too high. The ratchet mechanism is mounted on the take-up wheel to prevent it from reversing. The take-up thread-cutting device is located between the take-up wheel and the waste thread bin, and is used to cut the thread entering the waste thread bin into smaller segments. The thread drawn from the thread roll is wound around the spinning wheel after passing through a first guide wheel, then passes through a second guide wheel and enters the oiling system. The thread exiting the oiling system passes through a third guide wheel and enters the cleaning system. The thread exiting the cleaning system is pulled by the take-up device, wound around the take-up wheel several times, and then moved towards the waste thread bin by the take-up wheel. The thread entering the cleaning system is wound around the welding wire for cleaning, and the direction of movement of the thread is opposite to that of the welding wire.
[0008] In this invention, cotton thread is wound around the welding wire and kept under tension to ensure close contact. As the welding wire moves, foreign matter on its surface is transferred to the cotton thread, thus cleaning the wire. The cotton thread is automatically supplied by a winding device, maintaining its cleanliness at all times, while contaminated thread is discarded into a waste wire bin. Rust-preventive oil is stored in an oil mist generator. High-pressure air carries the oil mist into the immersion chamber, where it is evenly distributed in the air, ensuring uniform contact between the oil mist and the cotton thread surface. After passing through a tensioning device and a guide wheel, the cotton thread remains wound around the welding wire surface several times under tension. As the welding wire moves, conductive oil is evenly applied to the surface of the welding wire.
[0009] Furthermore, the first driving device includes a pay-off reel timing belt and a pay-off stepper motor. The pay-off stepper motor is connected to the timing pulley via the pay-off reel timing belt to drive the timing pulley to rotate the pay-off shaft. The second driving device includes a take-up stepper motor and a take-up reel timing belt. The take-up stepper motor is connected to the take-up reel via the take-up reel timing belt to drive the take-up reel to move the cotton thread toward the waste thread spool.
[0010] Furthermore, a slider is installed on the dance wheel, and the slider is slidably mounted on the linear rail. An inclined iron plate is provided on the upper part of the slider. The analog sensor is located on one side of the linear rail to detect the distance between the sensor and the inclined iron plate, thereby determining the specific position of the dance wheel within its stroke range.
[0011] Furthermore, the oil immersion system includes an oil mist generator and an oil immersion chamber. The oil mist generator is disposed above the oil immersion chamber and is used to generate oil mist into the oil immersion chamber.
[0012] Furthermore, the guide wheel assembly includes a guide wheel and a guide wheel bracket. The guide wheel is mounted on the guide wheel bracket and can rotate freely. The guide wheel bracket is fixed by a positioning block.
[0013] Furthermore, the emergency wire cutting device of the wire feeding system includes emergency wire cutting scissors and an emergency wire cutting cylinder for driving the emergency wire cutting scissors, and the wire cutting device of the wire take-up system includes take-up system wire cutting scissors and a take-up system wire cutting cylinder for driving the take-up system wire cutting scissors.
[0014] Furthermore, it includes a control system and a speed measuring wheel assembly. The control system includes a PLC and a control panel. The control panel is equipped with a start switch, a take-up speed selection knob, an oil injection quantity selection knob, a take-up wheel clamping button, and a wire cutting button. The speed measuring wheel assembly includes three wire guide wheels, one of which is located above the welding wire, and the other two wire guide wheels are located below the welding wire.
[0015] Furthermore, a metal plate is installed on the wire guide wheel located above the welding wire. The metal plate can be detected by a metal detection sensor. The metal detection sensor and the wire guide wheel together form a meter counting wheel.
[0016] In this invention, a rolled cotton thread is used. The thread roll is in the shape of a disc and fixed on a feed shaft. Pressure plates on both sides of the disc-shaped thread prevent the roll from unraveling due to tension. The thread roll uses an active feed mechanism. The feed motor can determine whether to rotate and its rotation speed based on the position of the spinning wheel. When the motor rotates in the forward direction, the thread is released from the roll. When the spinning wheel is pulled close to its highest point by the thread, an emergency thread-cutting device is activated to cut off the thread at the point where it exits the roll, preventing the thread from being abnormally pulled out of the roll. The tension control device consists of four parts: a spinning wheel, a linear guide, an inclined metal plate, and a sensor. The spinning wheel is mounted on the linear guide slider. The cotton thread is wound around the spinning wheel once, and the movement of the cotton thread drives the spinning wheel to rotate and move up and down. An analog sensor works with the inclined metal plate to constantly detect the height of the spinning wheel. A PLC controls the wire feeding motor to feed the wire, keeping the spinning wheel at the target position (generally the middle of the spinning wheel's stroke). Active wire feeding can achieve tension with minimal fluctuations. The tension of the cotton thread can be adjusted by adding or removing counterweights at the position of the spinning wheel. The oil mist generator is driven by high-pressure air and distributes the conductive oil in the oil reservoir as an oil mist in the oil immersion chamber. The oil immersion chamber is a sealed box with a cover that can be closed and opened for easy wire threading. It has two small wire passage holes on both sides. The cotton thread moves in the oil immersion chamber at a certain speed, and the misty conductive oil comes into uniform contact with the cotton thread. The cotton thread acts as a carrier of the conductive oil, carrying the conductive oil towards the welding wire. The oil mist inside the oil immersion chamber settles and becomes liquid, which is then collected and stored in a waste oil box. The welding wire reel directly contacts the bottom of the V-groove of the guide reel to position the welding wire, while the cotton thread is wound around the welding wire. The welding wire and the cotton thread move in opposite directions. The distance between the guide reel and the welding wire can be adjusted as needed, moving them closer or further away from the welding wire. The cotton thread is wound several times around the welding wire, the number of turns depending on the cleanliness of the welding wire, line speed, friction, tension, etc. More turns are needed for heavily contaminated welding wire, less turns for high tension, and less turns if the welding wire pulls on the cotton thread. The cotton thread is wound several times on the take-up reel, and the pressure wheel cylinder extends, ensuring a tight fit between the pressure wheel, the cotton thread, and the take-up reel. This makes it less likely for the cotton thread wound on the take-up reel to be pulled out in the opposite direction. There is a risk that abnormalities such as joints on the welding wire might cause the welding wire to pull on the cotton thread, potentially pulling it off the take-up reel. In this case, the ratchet mechanism on the take-up reel prevents this from happening. After use, the cotton thread is cut into shorter segments before being discarded into the waste thread bin. This prevents the cotton thread from being pulled out by the welding wire, which could lead to abnormalities such as the waste cotton thread entering the equipment.
[0017] In this invention, the speed measuring wheel assembly consists of three guide wheels: two below the welding wire and one above. These wheels rotate with the welding wire. A metal block is mounted on one of the guide wheels, rotating with it. A metal detection sensor detects this block; each detection corresponds to one rotation of the guide wheel. Knowing the circumference of the guide wheel allows for the determination of the welding wire's linear speed, thus enabling wire speed measurement. The stepper motor speed is automatically controlled based on the welding wire's linear speed. The degree of surface contamination on the welding wire is visually observed, and a knob is manually adjusted to compensate for the contamination level above the take-up motor speed. The cotton thread drives the spinning wheel up and down. An analog sensor feeds the wheel's position back to the PLC. The PLC compares the current wheel position with the target wheel position and adjusts the feed motor speed and direction to keep the pendulum positioned close to the middle of the wheel's travel.
[0018] In this invention, if the welding wire has a joint or excessive tension, it may cause the cotton thread to move along with it. The take-up reel is equipped with a ratchet mechanism (ratchet anti-reverse device) to ensure that the take-up reel can only rotate in the take-up direction. Simultaneously, to prevent the welding wire from causing the cotton thread to move, the cotton thread is prevented from being pulled out of the unwinding reel or waste thread bin. The height of the tension device's roller is constantly monitored; if it is at a high position or the upper limit of its stroke, the scissors are activated to cut the cotton thread, preventing it from being pulled out of the reel. Cotton thread that has been wiped with welding wire is cut before entering the waste thread bin, completely preventing waste cotton thread from being pulled out of the waste thread bin, forming a double safety mechanism with the take-up reel's ratchet mechanism.
[0019] The present invention also provides another wire grating machine, including a wire feeding and take-up system, a tension control system, an oil immersion system, a cleaning system, and a safety system. The wire feeding and take-up system includes a wire feeding device and a wire taking-up device. The wire feeding device includes a synchronous pulley, a wire feeding shaft for holding the cotton thread roll, and a first drive device for driving the wire feeding shaft to rotate. The wire taking-up device includes a take-up wheel, a second drive device for driving the take-up wheel to rotate, a wire pressing device, and a waste wire hopper. The wire pressing device is located on one side of the take-up wheel, and the waste wire hopper is located below the take-up wheel. The tension control system includes a chaff wheel, a tension arm, a tension arm rotation shaft, a lower limit block, and an upper limit block located below the wire feeding device. One end of the tension arm is connected to the chaff wheel, and the other end of the tension arm is provided with... The system includes a counterweight, a tension arm rotation shaft at the middle of the tension arm, a lower limit block and an upper limit block for limiting the tension arm, an oiling system located above one side of the dance wheel, a cleaning system comprising two spaced-apart guide wheel groups, and a safety system comprising an emergency thread-cutting device for the thread-feeding system, a ratchet mechanism, and a thread-cutting device for the thread-retrieving system.

The thread-cutting device for the thread-retrieving system is located between the thread-retrieving wheel and the waste thread bin and is used to cut the thread entering the waste thread bin into smaller segments.

The take-up and pay-off system includes a pay-off device and a take-up device. The pay-off device includes a synchronous pulley and a pay-off shaft for holding the cotton thread roll.

[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] This utility model discloses a welding wire wiping machine, comprising a wire feeding and take-up system, a tension control system, an oil immersion system, a cleaning system, a safety system, and a control system. During welding wire production, consumables (cotton thread) wound around the welding wire are used to clean foreign matter from the wire surface. The consumables are automatically replenished to ensure that only clean consumables are in contact with the welding wire, preventing secondary contamination. Rust-preventive oil can be applied to the consumable surface to extend the welding wire's shelf life, improve wire feeding, and enhance conductivity between the welding wire and the nozzle, thus improving welding quality.

[0030] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0031] Please see Figures 1 to 3 This embodiment provides a wire brushing machine, including a wire take-up and unwinding system, a tension control system, an oil immersion system, a cleaning system, a safety system, a control system, and a speed measuring wheel assembly, with the specific structure as follows:
[0032] The thread feeding and take-up system includes a feeding device and a take-up device. The feeding device includes a timing pulley 3, a feeding shaft 1 for holding the cotton thread roll 2, and a first drive device for driving the feeding shaft 1 to rotate.

The feeding shaft 1 is connected to the timing pulley 3 by the feeding stepper motor 5 through the timing belt 4. The timing pulley 3 drives the feeding shaft 1 to rotate under the drive of the feeding stepper motor 5 and the timing belt 4. The take-up device includes a take-up pulley 20, a second drive device, a pressing device, and a waste thread hopper 27. The second drive device includes a take-up stepper motor 21 and a timing belt 22 for the take-up pulley. The take-up stepper motor 21 is connected to the take-up pulley 20 through the timing belt 22 to drive the take-up pulley 20 to move the cotton thread 18 towards the waste thread hopper 27. The wire pressing device is located on one side of the take-up reel 20, and the waste wire hopper 27 is located below the take-up reel 20.
[0033] In one specific embodiment, the tension control system includes a wire rail 6, a roller 7, and an analog sensor 10 located below the wire feeding device. A slider 8 is mounted on the roller 7 and slidably mounted on the wire rail 6. An inclined iron plate 9 is positioned above the slider 8. The analog sensor 10 is located on one side of the wire rail 6. The analog sensor 10 determines the actual position of the roller 7 within its stroke range by detecting the distance between itself and the inclined iron plate 9. An oil immersion system is located above one side of the roller 7. The oil immersion system includes an oil mist generator 13 and an oil immersion chamber 14. The oil mist generator 13 is positioned above the oil immersion chamber 14 and is used to generate oil mist into the oil immersion chamber 14. The cleaning system includes two spaced-apart guide wheel sets. Each guide wheel set includes a guide wheel 17 and a guide wheel bracket. The guide wheel is mounted on the guide wheel bracket and can rotate freely. The guide wheel bracket is fixed by a positioning block 16.
[0034] In one specific embodiment, the safety system includes an emergency wire cutting device for the pay-off system, a ratchet mechanism 19, and a wire cutting device for the take-up system. The emergency wire cutting device for the pay-off system is located between the pay-off shaft 1 and the rotating wheel 7. The ratchet mechanism 19 is mounted on the take-up wheel 20 to prevent the take-up wheel 20 from reversing. The wire cutting device for the take-up system is located between the take-up wheel 20 and the waste wire spool 27. Specifically, the emergency wire cutting device for the pay-off system includes emergency wire cutting scissors 11 and an emergency wire cutting cylinder 12 for driving the emergency wire cutting scissors 11. The wire cutting device for the take-up system includes take-up wire cutting scissors 25 and a take-up wire cutting cylinder 26 for driving the take-up wire cutting scissors 25.
[0035] In one specific embodiment, the control system includes a PLC and a control panel 31. The control panel 31 is equipped with a start switch 32, a take-up speed selection knob 33, an oil injection quantity selection knob 34, a take-up reel clamping button 35, and a wire cutting button 36. The speed measuring wheel assembly includes three wire guide wheels, one of which is positioned above the welding wire 30, and the other two are positioned below the welding wire 30. A metal plate is mounted on the wire guide wheel above the welding wire 30. The metal plate can be detected by a metal detection sensor 28. The metal detection sensor 28 and the wire guide wheel it is located on together form a meter counting wheel 29.
[0036] The general working process of the welding wire brushing machine of this utility model is as follows:
[0037] The end of the cotton thread 18 is removed from the cotton thread roll 2, passes through the first guide wheel 15.1 and then through the emergency thread cutter 11 to enter the tension control system. The cotton thread 18 is wound once around the dance wheel 7, then passes through the second guide wheel 15.2 and enters the oiling system. During the winding process of the cotton thread 18, the cotton thread 18 drives the slider 8 installed below the dance wheel 7 to move on the rail 6. The analog sensor 10 determines the position of the dance wheel 7 within its stroke range by detecting the distance between the inclined iron plates 9 installed on the slider 8. Then, the PLC controls the rotation speed and direction of the unwinding stepper motor 5 to achieve relative stability of the position of the dance wheel 7. In this process, the slider drives the inclined metal plate to move, and the distance between the inclined metal plate and the sensor changes. The sensor then converts the distance signal into an electrical signal, thereby measuring the distance between the sensor and the inclined plate. The PLC program then converts the electrical signal into the position of the dance wheel.
[0038] Before the cotton thread 18 enters the oil immersion system, add conductive oil to the oil mist generator 13 and set the appropriate driving air pressure and oil outlet position. Open the top cover of the oil immersion chamber 14, insert the cotton thread 18 into the oil immersion chamber 14 through the inlet hole, and then out through the outlet hole. Cover the top cover of the oil immersion chamber 14, and the cotton thread 18 will leave the oil immersion system and enter the cleaning system through the third guide wheel 15.3. The cotton thread 18 enters the cleaning system through the third guide wheel 15.3, that is, between the two guide wheel sets. The guide wheel is mounted on the guide wheel bracket and can rotate freely. The guide wheel bracket can be tilted to move away from or close to the welding wire 30. After adjusting to the appropriate position, the guide wheel bracket is fixed to the positioning block 16, thus completing the fixation of the welding wire 30. The cotton thread 18 is wound around the welding wire 30 to prevent the tension of the cotton thread 18 from dragging, deforming, or shifting the welding wire 30. When the welding wire 30 moves from left to right, the cotton thread 18 moves from right to left. The cleaned cotton thread 18 continuously enters the cleaning system to wipe the welding wire 30 clean and evenly apply conductive oil.
[0039] The contaminated cotton thread 18 exiting the cleaning system is pulled by the take-up section of the take-up system. The pressure roller 23 is released and the contaminated cotton thread 18 is wound several times on the take-up roller 20. Then, the pressure cylinder 24 is driven to make the pressure roller 23 fit tightly against the surface of the take-up roller 20. The take-up stepper motor 21 drives the take-up roller 20 through the take-up roller synchronous belt 22, which moves the cotton thread 18 toward the waste wire bin 27. The PLC controls the take-up stepper motor 21 to rotate at an appropriate speed through the meter wheel 29 driven by the welding wire 30 and the take-up speed selection knob 33 on the control panel 31. The metal detection sensor 28 detects the rotation speed of the metal block on the meter wheel 29 to know the running speed of the welding wire 30. Then, the appropriate take-up speed knob 33 is selected by visually observing the degree of contamination on the surface of the welding wire 30. The dual take-up speed control allows the cotton thread 18 to clean the welding wire 30 without wasting cotton thread.
[0040] When the analog sensor 10 detects that the position of the dancing wheel 7 is too high, the PLC controls the emergency thread cutter 11 to cut the cotton thread 18, preventing the cotton thread 18 from being abnormally pulled out of the cotton thread roll 2. The take-up wheel 20 is equipped with a ratchet mechanism 19 to prevent the cotton thread 18 from being pulled back by the welding wire 30, ensuring that the already contaminated cotton thread 18 will not become a source of contamination and contaminate the welding wire 30. The thread cutter 25 driven by the thread cutting cylinder 26 cuts the cotton thread 18 that has entered the waste thread bin 27 into small segments, completely eliminating the possibility of the cotton thread 18 being carried out by the welding wire 30 and causing abnormalities.
[0041] The start switch 32 on the control panel 31 can control the start and stop of the equipment, while the oil spray quantity selection knob 34 can select the appropriate gear to control the amount of oil soaked in the cotton thread 18, which can ensure rust prevention and lubrication without over-oiling. The take-up reel clamping button 35 can control the opening and closing of the pressure wheel 23 during the threading process, and the thread cutting button 36 can control the emergency thread cutting scissors 11 of the thread feeding part of the take-up and feed system to cut the cotton thread 18, making the equipment both practical and safe.
