Description

Technical Field

[0001] This utility model belongs to the technical field of iron filings collection devices, specifically relating to an automatic iron filings collection device and a welding wire drawing device in a narrow area. Background Technology

[0002] In wire drawing equipment, a wire drawing die box is typically used to draw the welding wire. This is because the wire drawing die box contains a drawing die, which is rotatably connected to the box via bearings. A main sprocket is connected to one side of the drawing die, and the main sprocket is connected to a drive motor via a chain. The drive motor drives the chain to rotate, which in turn rotates the main sprocket, thus rotating the wire drawing die. The welding wire passes through the rotating drawing die, achieving the drawing process. The wire drawing die box also stores cooling water to prevent overheating and affecting the die's operation. However, water may seep into the bearings. Since the wire drawing die box is coated with drawing powder, if the water contains drawing powder or other oil contaminants, it can easily damage the bearings and cause them to stop rotating, forcing the drive motor to stop as well.

[0003] Under normal circumstances, with the drive motor running continuously, the welding wire may carry a small amount of iron filings after passing through the drawing die, but not a large amount. However, when the drive motor stops, the drawing die also stops rotating, and the welding wire continues to be drawn within the die. This causes the drawing die to wear down one side of the welding wire, increasing the wear on the wire and raising the temperature. As a result, long strips of flocculent iron filings and oxide scale will fall off when the welding wire exits the drawing die. Furthermore, since the surface of the welding wire is coated with drawing powder, the surface of the fallen long strips of flocculent iron filings and oxide scale also carries drawing powder. If iron filings and oxide scale are not cleaned up in time, they will accumulate higher and higher. The collision between the continuously generated iron filings and oxide scale will cause drawing powder to fly everywhere. The powder will not only pollute the environment but also harm the human body. When the iron filings and oxide scale accumulate too high, they can easily come into contact with the welding wire being drawn at high speed. The surface of the high-speed drawn welding wire has a temperature of at least 150°C. When the iron filings and oxide scale come into contact with the welding wire, they will ignite under the high temperature of the welding wire. In severe cases, it will smoke or even catch fire, causing a significant safety hazard. Utility Model Content

[0004] This invention provides an automatic iron filings collection device and a welding wire drawing device for confined areas, to solve the problem that existing iron filings are not collected in time, causing the iron filings and oxide scale to accumulate higher and higher. When the iron filings and oxide scale accumulate too high, they can easily come into contact with the welding wire being drawn at high speed. The surface of the high-speed drawn welding wire has a high temperature of at least 150°C. When the iron filings and oxide scale come into contact with the welding wire, they will ignite under the high temperature of the welding wire, and in severe cases, they may smoke or even catch fire, causing significant safety hazards.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An automatic iron filings collection device for a confined area is connected to the base of the equipment corresponding to the iron filings outlet; it includes a housing, a dust suction mechanism, and a collection mechanism.

[0007] The housing is connected to the base of the equipment. A dust collection mechanism is connected inside the housing, and a collection mechanism is provided on the outside of the housing away from the iron filings outlet.

The dust collection disc is connected to the transmission mechanism, and the drive mechanism is connected to the transmission mechanism. The drive mechanism drives the transmission mechanism to move the dust collection disc relative to the housing. After the iron filings are output from the iron filings outlet, they can be adsorbed onto the housing under the suction of the dust collection disc.

[0022] The transmission mechanism further includes a first auxiliary sprocket and a second auxiliary sprocket; the first auxiliary sprocket is connected to the outside of the first transmission chain, and the second auxiliary sprocket is connected to the inside of the first transmission chain, and the first transmission chain is tensioned by the first auxiliary sprocket and the second auxiliary sprocket.

[0023] The dust collection tray includes a tray body and pulleys; one side of the tray body has a connecting end that is connected to the first transmission chain; multiple pulleys are connected to the bottom of the tray body, and the pulleys are symmetrically arranged on both sides in the radial direction. The tray body is slidably connected to the track through the pulleys.

[0024] The scraper assembly includes a connecting shaft and a scraper; one side of the connecting shaft is connected to a drive device, and the other side of the connecting shaft is perpendicularly connected to the scraper, which is arranged along the extension direction of the housing to push iron filings on the housing.

[0025] This application also relates to a welding wire drawing device, including a base, a wire winding machine, a wire drawing die box, a wire drawing machine, and an automatic iron filings collection device in a narrow area as described above;

[0026] The base is connected to a wire winding machine, a wire drawing die box, and a wire drawing machine; the wire drawing machine is located on one side of the base, and the wire drawing die box and the wire winding machine are located on the other side of the base; the welding wire is wound on the wire winding machine, and the output end of the welding wire is initially drawn through the wire drawing die box, and after being output through the iron chip outlet of the wire drawing die box, it is wound onto the wire drawing machine for secondary drawing; the housing is connected to the base below the iron chip outlet;

[0027] When the welding wire is discharged through the scrap outlet, scrap will be discharged. The dust collection mechanism moves the scrap from the scrap outlet side of the housing to the collection mechanism side and collects it.

[0028] The wire winding machine includes a connector and a winding roller; one end of the connector is fixedly connected to the base, and the other end of the connector extends beyond the base; the winding roller is rotatably connected to the end of the connector that extends beyond the base; welding wire is wound on the winding roller.

[0029] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0030] 1. This utility model relates to an automatic iron filings collection device in a confined area, connected to the base of the equipment corresponding to the iron filings outlet; it includes a housing, a dust collection mechanism, and a collection mechanism; the housing is connected to the base of the equipment, the dust collection mechanism is connected inside the housing, and the collection mechanism is provided on the outer side of the housing away from the iron filings outlet; the dust collection mechanism includes a dust collection disc, a transmission mechanism, and a drive mechanism; the dust collection disc is connected to the transmission mechanism, and the drive mechanism is connected to the transmission mechanism, the drive mechanism drives the transmission mechanism to move the dust collection disc relative to the housing; after the iron filings are output from the iron filings outlet, they can be adsorbed onto the housing under the suction of the dust collection disc, and the movement of the dust collection disc drives the iron filings from the side of the housing near the iron filings outlet to the side of the housing near the collection mechanism; the collection mechanism includes a scraper assembly, a drive device, and a collection frame; the scraper assembly is connected to the top of the housing through the drive device, and the collection frame is connected to the housing corresponding to the scraper assembly, the drive device drives the scraper assembly to push the iron filings on the housing into the collection frame.

[0031] The housing is positioned corresponding to the iron filings outlet. When iron filings are output from the outlet, the dust collection disc of the dust collection mechanism is energized and magnetically attracts the iron filings to the top of the housing. Then, the drive mechanism of the dust collection mechanism drives the transmission mechanism to move the dust collection disc along the housing to the side of the housing near the collection mechanism. Then, the power supply to the dust collection disc is disconnected, causing the magnetic force of the dust collection disc to disappear. Then, the drive mechanism drives the transmission mechanism to move the dust collection disc back to the initial position of the housing, continuously transporting the iron filings to one side of the housing for centralized collection. This achieves automated collection of iron filings, timely cleaning of iron filings, and avoids iron filings accumulating too high and coming into contact with the high-temperature welding wire, which could cause sparks or even smoke and fire, thus ensuring operational safety.

[0032] 2. In a preferred embodiment of the present invention, a first weighing sensor and a first photoelectric sensor are connected to the side of the housing near the iron filings outlet, and a second weighing sensor and a second photoelectric sensor are connected to the side of the housing near the collecting mechanism.

[0033] By setting a first weighing sensor, it is possible to determine whether the iron filings near the filings outlet of the housing have reached a preset threshold, facilitating timely transport of the iron filings to the side of the housing near the collection mechanism. By setting a first photoelectric sensor, it is possible to accurately determine whether the suction disc is in its initial position. Once the first photoelectric sensor detects that the suction disc has returned to its initial position, it feeds back to the controller, which then controls the suction disc to be powered on again to resume its ability to attract iron filings. Similarly, by setting a second weighing sensor, it is possible to promptly determine whether the iron filings have reached a preset threshold, facilitating timely control of the scraper assembly to push the iron filings into the collection frame. By setting a second photoelectric sensor, it is possible to accurately determine whether the suction disc is in its end position. Once the suction disc is detected in its end position, it feeds back to the controller, which then controls the suction disc to be powered off, causing the magnetic force to disappear and preventing the suction disc from bringing the iron filings back on its return trip.

[0034] 3. In a preferred embodiment of the present invention, the transmission mechanism includes a first transmission chain assembly, a second transmission chain assembly, and a track.

[0035] The first drive chain assembly moves the vacuum disk, and the second drive chain assembly is connected to the drive mechanism to drive the first drive chain assembly. The drive mechanism changes the direction of the second drive chain assembly to adjust the direction of the first drive chain assembly, thereby changing the direction of the vacuum disk along the track.

[0046] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0047] Example 1

[0048] This utility model relates to an automatic iron filings collection device in a confined area, such as... Figure 1-2 As shown, the base 9 connected to the equipment corresponds to the scrap outlet; it includes a housing 1, a dust collection mechanism, and a collection mechanism;

[0049] The housing 1 is connected to the base 9 of the equipment. A dust collection mechanism is connected inside the housing 1, and a collection mechanism is provided on the outside of the housing 1 away from the iron filings outlet.

[0050] The dust collection mechanism includes a dust collection disc 2, a transmission mechanism 3, and a drive mechanism. The dust collection disc 2 is connected to the transmission mechanism 3, and the drive mechanism is connected to the transmission mechanism 3. The drive mechanism drives the transmission mechanism 3 to move the dust collection disc 2 relative to the housing 1. After the iron filings are output from the iron filings outlet, they can be adsorbed onto the housing 1 under the suction of the dust collection disc 2. The movement of the dust collection disc 2 drives the iron filings to move from the side of the housing 1 near the iron filings outlet to the side of the housing 1 near the collection mechanism.

[0051] The collection mechanism includes a scraper assembly 4, a drive device 5, and a collection frame 6. The scraper assembly 4 is connected to the upper part of the housing 1 via the drive device 5, and the collection frame 6 is connected to the housing 1 corresponding to the scraper assembly 4. The drive device 5 drives the scraper assembly 4 to push the iron filings on the housing 1 into the collection frame 6.

[0052] The automatic iron filings collection device for confined areas of this application has a simple structure, small size, and does not occupy much space. It is suitable for confined areas and can be directly installed in the spare space of the equipment corresponding to the iron filings outlet position. If there is no extra space in the equipment, a bracket can be installed at the bottom of the collection device, i.e., the bottom of the housing 1, so that the automatic iron filings collection device in the entire confined area corresponds to the iron filings outlet position. The collection device of this application can adsorb and collect the iron filings at the iron filings outlet.

[0053] The housing 1 adopts a U-shaped elongated structure. Inside the housing 1 is a dust collection mechanism. When the dust collection disc 2 of the dust collection mechanism is located on the side of the housing 1 near the iron filings outlet, this position is recorded as the initial position of the dust collection disc 2. When the dust collection disc 2 is located on the side of the housing 1 near the collection mechanism, this position is recorded as the end position of the dust collection disc 2.

[0054] A collection mechanism is located on the outer side of the housing 1, perpendicular to the extension direction of the housing 1, so that the scraper assembly 4 can push the iron filings into the collection frame 6 connected to the outside of the housing 1 along the extension direction perpendicular to the housing 1. When the first photoelectric sensor detects that the dust collection disc 2 is in the initial position near the iron filings outlet, it feeds a signal back to the controller. The controller controls the coil to be energized, making the dust collection disc 2 magnetic. The dust collection disc 2 adsorbs the iron filings output from the iron filings outlet, so that the iron filings are adsorbed above the housing 1. After the first weighing sensor detects that the weight of the iron filings exceeds the set threshold, the drive mechanism in the dust collection mechanism drives the transmission mechanism 3 to run. The transmission mechanism 3 drives the dust collection disc 2 to move relative to the housing 1, transporting the iron filings from the iron filings outlet side to the side of the housing 1 where the collection mechanism is located. After the dust collection disc 2 transports the iron filings to the side of the housing 1 where the collection mechanism is located, the iron filings are then transported to the collection mechanism. When the second photoelectric sensor detects that the dust collection disk 2 is on one side of the collection mechanism of the housing 1, that is, when the dust collection disk 2 is at the end position, the second photoelectric sensor feeds back the detected data to the controller. The controller controls the circuit to disconnect, so that the coil connected to the dust collection disk 2 is de-energized. At this time, the dust collection disk 2 is in the demagnetization stage. Then, the drive mechanism of the dust collection mechanism drives the transmission mechanism 3 to drive the dust collection disk 2 back to the initial position. At this time, since the dust collection disk 2 is demagnetized and has no magnetism, it will not bring the iron filings back to the initial position. There is also a second weighing sensor on the side of the housing 1 where the collection mechanism is located. After the second weighing sensor detects that the weight of the iron filings above the housing 1 exceeds the set threshold, the drive device 5 drives the scraper assembly 4 to move along the extension direction perpendicular to the housing 1, so that the scraper assembly 4 pushes the iron filings on the housing 1 into the collection frame 6 for collection. Staff only need to clean the iron filings in collection box 6, avoiding the traditional method of scattering and being unable to collect iron filings. The powder from the welding wire carried by the iron filings diffuses into the air, greatly reducing environmental pollution and harm to the body, and further ensuring the safe operation of the equipment and the safety of personnel.

[0055] In a preferred embodiment, a first weighing sensor and a first photoelectric sensor are connected to the side of the housing 1 near the iron filings outlet, and a second weighing sensor and a second photoelectric sensor are connected to the side of the housing 1 near the collection mechanism. The first weighing sensor is used to measure the weight of the iron filings at the iron filings outlet, and the first photoelectric sensor is used to detect whether the suction disk 2 is in the initial position. When the weight of the iron filings reaches a set threshold, the suction disk 2 in the initial position is energized to generate magnetism, and the suction disk 2 is driven by the transmission mechanism 3 to attract iron filings and move to the side of the collection mechanism. The second weighing sensor is used to measure the weight of the iron filings on the side of the collection mechanism, and the second photoelectric sensor is used to detect whether the suction disk 2 is on the side of the collection mechanism. When the weight of the iron filings reaches the set threshold, the suction disk 2 is de-energized and demagnetized, and the scraper assembly 4 pushes the iron filings into the collection frame 6.

[0056] The dust collection disk 2 cannot remain magnetic indefinitely. Otherwise, after the iron filings attracted from the initial position are transported to the end position, they will be drawn back to the initial position by the magnetic dust collection disk 2. Therefore, the dust collection disk 2 needs to be energized or de-energized to ensure it becomes magnetic when energized or loses its electromagnetic properties when de-energized. When the dust collection disk 2 is in the initial position, the first photoelectric sensor detects this and sends feedback to the controller. The controller then energizes the control circuit, causing the dust collection disk 2 to generate an electromagnetic field. As the iron filings fall from the iron filings outlet, they are attracted to the side of the housing 1 near the iron filings outlet by the magnetic force of the dust collection disk 2 below. The drive mechanism then drives the transmission mechanism 3 to move the dust collection disk 2. Because of its magnetic force, the dust collection disk 2 can move the iron filings from the side of the housing 1 near the iron filings outlet to the side near the collection mechanism. After the dust collection disk 2 reaches one side of the collection mechanism, the second photoelectric sensor detects that the dust collection disk 2 is at the end position. At this time, the feedback is sent to the controller, and the controller control circuit is disconnected, so that the electromagnetic force of the dust collection disk 2 disappears. The drive mechanism drives the transmission mechanism 3 to drive the dust collection disk 2 back to the initial position. At this time, since the dust collection disk 2 does not have magnetic force, it will not transport the iron filings located on the side of the housing 1 near the collection mechanism back to the side of the iron filings outlet. This enables the iron filings on the side of the iron filings outlet to be transported to the side of the collection mechanism of the housing 1, so that they can be collected by the collection mechanism later.

[0057] After the iron filings are output from the iron filings outlet and are attracted to the housing 1 by the magnetic force of the dust collection disc 2, the weight of the iron filings is detected in real time by the first weighing sensor. When the weight reaches the preset threshold, the sensor sends a signal to the controller, which then controls the drive mechanism to drive the transmission mechanism 3. The transmission mechanism 3 moves the dust collection disc 2 from the initial position to the end position. This process is repeated to continuously transport the iron filings from the iron filings outlet side to the collection mechanism side of the housing 1. When the second weighing sensor detects that the weight of the iron filings on the housing 1 has reached the preset threshold, the sensor sends a signal to the controller, which then controls the drive device 5 of the collection mechanism. The drive device 5 drives the scraper assembly 4, which pushes the iron filings above the housing 1 into the collection frame 6 for collection.

[0058] The housing 1 of this application is also connected to a controller, which is connected to the first photoelectric sensor, the second photoelectric sensor, the first weighing sensor, the second weighing sensor, the drive mechanism and the drive device 5. The controller makes real-time judgments and analyses based on the data fed back by the first photoelectric sensor, the second photoelectric sensor, the first weighing sensor and the second weighing sensor, so as to control the stop and operation of the drive mechanism and the drive device 5.

[0059] In a preferred embodiment, the transmission mechanism 3 includes a first transmission chain assembly 31, a second transmission chain assembly 32, and a track 33; the track 33 is connected inside the housing 1 and extends from the iron filings outlet side to the collection mechanism side; the dust collection disc 2 is slidably connected to the track 33; the first transmission chain assembly 31 is connected to the dust collection disc 2; one end of the second transmission chain assembly 32 is connected to the first transmission chain assembly 31, and the other end of the second transmission chain assembly 32 is connected to the drive mechanism, which drives the second transmission chain assembly 32 to rotate the first transmission chain assembly 31 so that the dust collection disc 2 moves along the track 33.

[0060] like Figure 2 As shown, the first transmission chain assembly 31 of the transmission mechanism 3 is distributed along the length direction of the housing 1, and the second transmission chain assembly 32 is inclined to the first transmission chain assembly 31. The purpose of the second transmission chain assembly 32 being connected to the drive mechanism is to drive the second transmission chain assembly 32 to rotate forward or backward, thereby changing the rotation direction of the first transmission chain assembly 31. This drives the dust collection disc 2 connected to the first transmission chain assembly 31 to move along the track 33, so that the dust collection disc 2 can move from the initial position to the end position or from the end position to the initial position along the housing 1. This enables the iron filings to be continuously transported from the side of the housing 1 near the iron filings outlet to the side near the collection mechanism, facilitating the subsequent collection of the iron filings.

[0061] The drive mechanism uses a DD motor. The advantages of DD motors are high precision and high repeatability, making them very suitable for movement in confined areas.

[0062] In a preferred embodiment, the first transmission chain assembly 31 includes a first transmission chain 311, a first transmission sprocket 312, and a second transmission sprocket 313; the first transmission sprocket 312 is rotatably connected to the housing 1 near the scrap outlet, and the second transmission sprocket 313 is rotatably connected to the housing 1 near the collection mechanism; one end of the first transmission chain 311 is connected to the first transmission sprocket 312, and the other end of the first transmission chain 311 is connected to the second transmission sprocket 313; one side of the dust collection disc 2 is fixedly connected to the first transmission chain 311.

[0063] The first transmission sprocket 312 is rotatably connected to the housing 1 via the first rotating shaft, and the second transmission sprocket 313 is rotatably connected to the housing 1 via the second rotating shaft.

[0064] For ease of description, such as Figure 2 As shown in the diagram, the first transmission sprocket 312 is located on the right side of housing 1, while the second transmission sprocket 313 and the third transmission sprocket 322 are located on the left side of housing 1. The third transmission sprocket 322 is located at... Figure 2 Above the second drive sprocket 313 in the indicated position, one end of the first drive chain 311 is connected to the first drive sprocket 312, and the other end of the first drive chain 311 is connected to the second drive sprocket 313; the track 33 of the dust collection disc 2 is connected inside the housing 1 and located below the first drive chain 311, so that the dust collection disc 2 can be connected inside the first drive chain 311. One end of the dust collection disc 2 is fixedly connected to the first drive chain 311, so that when the first drive chain 311 rotates, it can drive the dust collection disc 2 to move linearly along the track 33.

[0065] One end of the second transmission chain 321 is connected to the second transmission sprocket 313, and the other end is connected to the third transmission sprocket 322. The third transmission sprocket 322 is connected to the drive mechanism, which can be a DD motor. DD motors offer advantages such as high precision and high repeatability, making them ideal for movement in confined spaces. The output shaft of the DD motor is connected to the third transmission sprocket 322. Rotation of the output shaft drives the third transmission sprocket 322, thereby rotating the second transmission chain 321. When the second transmission chain 321 rotates clockwise, the second transmission sprocket 313 rotates clockwise, causing the first transmission chain 311 to rotate clockwise. At this time, the dust collection disc 2 moves from its initial position to its end position under the rotation of the first transmission chain 311. When it is necessary to move the dust collection disc 2 from its end position to its initial position, the motor is reversed, causing the second transmission chain 321 to rotate counterclockwise, which in turn causes the first transmission chain 311 to rotate counterclockwise.

[0066] In a preferred embodiment, the second transmission chain assembly 32 includes a second transmission chain 321 and a third transmission sprocket 322; the third transmission sprocket 322 is rotatably connected to the side of the housing 1 near the collecting mechanism, and the third transmission sprocket 322 is connected to the driving mechanism; one end of the second transmission chain 321 is connected to the third transmission sprocket 322, and the other end of the second transmission chain 321 is connected to the second transmission sprocket 313.

[0067] The third drive sprocket 322 can be a separate third shaft, fixedly connected to the output shaft of the motor, or the output shaft of the motor can be used as the third shaft of the third drive sprocket 322, allowing the third drive sprocket 322 to be rotatably connected to the housing 1. The first drive chain 311, the first drive sprocket 312, and the second drive sprocket 313 constitute a chain-sprocket drive, and the second drive chain 321 and the third drive sprocket 322 constitute a chain-sprocket drive, thereby achieving smooth movement of the dust collection disc 2.

[0068] In a preferred embodiment, the transmission mechanism 3 further includes a first auxiliary sprocket 7 and a second auxiliary sprocket 8; the first auxiliary sprocket 7 is connected to the outside of the first transmission chain 311, and the second auxiliary sprocket 8 is connected to the inside of the first transmission chain 311, so that the first transmission chain 311 is tensioned by the first auxiliary sprocket 7 and the second auxiliary sprocket 8.

[0069] Because the first transmission chain 311 has a relatively long transmission distance, to prevent wear and elongation of the first transmission chain 311 during long-term operation, which could lead to loose edges and affect transmission stability, the transmission mechanism 3 is also equipped with a first auxiliary sprocket 7 and a second auxiliary sprocket 8, such as... Figure 2 As shown, the first auxiliary sprocket 7 meshes with the first transmission chain 311 and is located on the outside of the first transmission chain 311, while the second auxiliary sprocket 8 meshes with the first transmission chain 311 and is located on the inside of the first transmission chain 311, thereby achieving internal and external tensioning of the first transmission chain 311, enhancing the smooth operation of the first transmission chain 311, and ensuring reliable transmission.

[0070] In a preferred embodiment, the dust collection tray 2 includes a tray body 21 and pulleys 22; one side of the tray body 21 has a connecting end connected to the first transmission chain 311; a plurality of pulleys 22 are connected to the bottom of the tray body 21, the pulleys 22 are symmetrically arranged on both sides in the radial direction, and the tray body 21 is slidably connected to the track 33 through the pulleys 22.

[0071] The dust collection disk 2 has a magnetic main structure 21 which plays the role of adsorbing iron filings. The disk 21 has a circular structure and multiple pulleys 22 are connected to the bottom of the disk 21. In this application, four pulleys 22 are provided, with two pulleys 22 on each side along the radial direction of the disk 21. The pulleys 22 can be slidably connected to the track 33, thereby enhancing the balance and stability of the dust collection disk 2 running on the track 33.

[0072] In a preferred embodiment, the scraper assembly 4 includes a connecting shaft 42 and a scraper 41; one side of the connecting shaft 42 is connected to the drive device 5, and the other side of the connecting shaft 42 is perpendicularly connected to the scraper 41, and the scraper 41 is arranged along the extension direction of the housing 1 to push the iron filings on the housing 1.

[0073] The connecting shaft 42 is fixedly connected to the driving device 5. The driving device 5 can be a linear module, which enables the connecting shaft 42 to move in a straight line, thereby driving the scraper 41 on one side of the connecting shaft 42 to move in a straight line. Since the scraper 41 is perpendicular to the connecting shaft 42 and parallel to the length direction of the housing 1, the scraper 41 can be pushed to move the iron filings above the housing 1 along the width direction of the housing 1. A collection frame 6 is connected to one side of the housing 1 along the width direction. The scraper 41 pushes the iron filings to fall into the collection frame 6 connected to the housing 1 for collection.

[0074] Example 2

[0075] like Figure 3 As shown, this application also relates to a welding wire drawing device, including a base 9, a wire winding machine 10, a wire drawing die box 11, a wire drawing machine 12, and an automatic iron filings collection device in a narrow area as described above.

[0076] A wire winding machine 10, a wire drawing die box 11, and a wire drawing machine 12 are connected to the base 9. The wire drawing machine 12 is located on one side of the base 9, and the wire drawing die box 11 and the wire winding machine 10 are located on the other side of the base 9. The welding wire is wound on the wire winding machine 10, and the output end of the welding wire is initially drawn through the wire drawing die box 11. After being output through the iron chip outlet of the wire drawing die box 11, it is wound onto the wire drawing machine 12 for secondary drawing. The housing 1 is connected to the base 9 below the iron chip outlet.

[0077] When the welding wire is discharged through the scrap outlet, scrap will be discharged. The dust collection mechanism moves the scrap from the scrap outlet side of the housing 1 to the collection mechanism side and collects it through the collection mechanism.

[0078] like Figure 3As shown, the automatic iron filings collection device for a confined area according to this application can be installed on the base 9 of the equipment, located near the front end of the base 9. A wire winding machine 10 and a wire drawing die box 11 are connected to the right side of the base 9, and a wire drawing machine 12 is connected to the left side of the base 9. Welding wire is wound on the wire winding machine 10 and undergoes preliminary drawing through the wire drawing die box 11. The diameter of the drawn wire is smaller than the diameter of the welding wire wound on the wire winding machine 10. During the process of the welding wire passing through the wire drawing die box 11, it is output from the inlet to the outlet, which is the iron filings outlet. The welding wire is output from the wire drawing die of the wire drawing die box. When the bearing assembly in the wire drawing die box is damaged, causing the main sprocket to stop rotating and thus the motor to stop rotating, the wire drawing die stops rotating. At this time, the wire drawing die causes unilateral wear on the welding wire, resulting in the drawn wire exiting from the iron filings outlet. When the wire drawing machine is output, long strips of flocculent iron filings and oxide scale will fall off, and the iron filings and oxide scale will also have drawing powder on them. If there is no collection device to collect the iron filings, they will pile up higher and higher. When the pile is too high, it will touch the welding wire that is being drawn at high speed. The surface of the welding wire reaches a high temperature of about 150°C, which will cause the iron filings to ignite, and may even cause smoke and fire, posing a safety hazard. The collection device of this application is connected to the base 9 corresponding to the iron filings outlet. The collection device surrounds the wire drawing machine 12, with one side extending to the bottom of the iron filings outlet and the other side surrounding one side of the wire drawing machine 12. The iron filings output from the iron filings outlet can be adsorbed onto the housing 1 by the dust collection mechanism inside the housing 1, and then transported from the side of the housing 1 near the iron filings outlet to the side of the housing 1 near the collection mechanism by the magnetic force of the dust collection disc 2 of the dust collection mechanism.

[0079] like Figure 3 As shown, the wire winding machine 10 includes a connector 101 and a winding roller 102; one end of the connector 101 is fixedly connected to the base 9, and the other end of the connector 101 extends beyond the base 9; the winding roller 102 is rotatably connected to the end of the connector 101 that extends beyond the base 9; welding wire is wound on the winding roller 102.

[0080] The wire drawing die box 11 contains a wire drawing die. One end of the welding wire is connected to the winding roller 102, and the other end of the welding wire is output from the winding roller 102 to the wire drawing die in the wire drawing die box 11. After the wire is initially drawn by the wire drawing die, it enters the wire drawing machine 12 for a second wire drawing, so that the diameter of the welding wire gradually decreases.
