Abstract

The present invention discloses a cathode wire production device for an electrostatic precipitator and a production method thereof, relating to the technical field of electrostatic precipitator cathode wire production equipment. In this solution, the cathode wire production device uses a cutting assembly to cut the cathode wire to form a main body and a bent portion, and uses a bending assembly to bend the bent portion so that the bent portion, which is at a preset angle to the main body, forms a discharge tip. In this solution, no waste is generated during the cathode wire production process, avoiding the need for additional collection equipment and ensuring the cleanliness of the work site. The cathode wire production device in this solution can quickly form a discharge tip on the cathode wire, significantly improving production efficiency compared to the traditional method of welding thorn sheets or needle-pricked bodies to the surface of a metal pipe. In this solution, the discharge tip is formed by directly bending the bent portion relative to the main body. Compared to the traditional method of welding two separate components, the connection between the bent portion and the main body in this solution is more secure and has higher stability in use.

Description

Technical Field

[0001] The present invention relates to the technical field of electrostatic precipitator cathode wire production equipment, in particular to an electrostatic precipitator cathode wire production device and a production method thereof. Background Art

[0002] Flexible cathode wires and rigid tubular cathode wires are two common types of cathode wires in electrostatic precipitators. Among them, flexible cathode wires are usually made of stainless steel sheets. During the preparation, stamping dies or laser cutting equipment are used to process serrated structures on the stainless steel sheets. A large amount of waste is generated during the punching process and scattered at the processing site, which on the one hand affects the on-site working environment, and on the other hand, separate collection equipment needs to be set up to collect and process the waste.

[0003] Hard tubular cathode wires are usually made of metal tubes (stainless steel). During preparation, a large number of barbed pieces or needle-pricked bodies are welded and fixed on the peripheral side wall of the metal tube in a staggered arrangement. In the above process, each barbed piece or needle-pricked body is welded separately, and before welding, the barbed piece or needle-pricked body needs to be adjusted to a predetermined placement position (so that the barbed piece or needle-pricked body abuts against the outer peripheral wall of the metal tube), resulting in low efficiency of the entire preparation process (unable to meet large-scale production needs); and during long-term use, due to the easy oxidation of the weld and some defects generated during the welding process (such as pores and slag inclusions), the corrosion resistance of the weld part is reduced, which will cause rust at the weld over time, thereby weakening the structural strength of the weld, and over time, the barbed piece or needle-pricked body will become loose and fall off, affecting the stability of the cathode wire.

[0004] Therefore, how to provide a cathode wire production device that does not generate waste during processing and has high production efficiency has become a technical problem that needs to be urgently solved in the field of electrostatic precipitator cathode wire production and processing.

For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0066] Reference Figures 1-15 As shown, in the first aspect, the embodiment of the present application proposes an electrostatic precipitator cathode wire production device, which has an X-direction, a Y-direction and a Z-direction intersecting each other, and includes a conveyor frame 1, the conveyor frame 1 having a feed end 11 and a discharge end 12 in the X-direction, and the conveyor frame 1 has a conveying component 13 for driving the cathode wire 7 from the feed end 11 to the discharge end 12. The cathode wire 7 is driven to move on the conveyor frame 1 by the conveying component 13; illustratively, this embodiment provides a specific structure of a conveying component 13, such as Figure 13 、 Figure 14 As shown, the conveying assembly 13 includes a plurality of drive assemblies 132 arranged along the X direction, wherein the drive assembly 132 includes a frame 1321 (one side of the frame 1321 is fixedly mounted on the conveying frame 1 via a fixing rod) and a drive roller group 1322, and the drive roller group 1322 includes a plurality of drive rollers rotatably mounted on the frame 1321, and several drive rollers located on the same frame 1321 can be driven by a motor together; or each drive roller can provide driving force, for example, the drive roller can be a built-in drive roller, that is, the drive motor assembly is built into the roller body, thereby reducing the external space occupied and improving the compactness and operation efficiency of the equipment; preferably, in this embodiment, the drive roller is selected as a built-in drive roller to convey the cathode line 7, which can better reduce the external space occupied; as shown Figure 13As shown, when the cathode line 7 is conveyed, the two driving components 132 cooperate with each other and are respectively located on the upper and lower sides of the cathode line 7 (the two driving components 132 constitute a driving node), so that the driving roller groups 1322 installed on the frame 1321 are both in contact with the upper and lower surfaces of the cathode line 7. When the driving rollers rotate, the cathode line 7 can be synchronously driven to move on the conveying frame 1 (the rotation directions of the driving roller groups 1322 located on the upper and lower sides of the cathode line 7 are opposite), and move from the feed end 11 to the discharge end 12; as shown Figure 4 As shown, a plurality of cooperating drive components 132 can be arranged at intervals in the X direction to realize the conveying of the cathode wire 7; in this embodiment, the plurality of cooperating drive components 132 are used to realize the driving of the cathode wire 7 to move on the conveying frame 1 on the one hand, and on the other hand, the effect of supporting the cathode wire 7 is also realized, so that the cathode wire 7 can be clamped by a plurality of cooperating drive components 132 on the conveying frame 1 and move from the feed end 11 to the discharge end 12; or a traction member is set at the discharge end 12 to drive the cathode wire 7 to move on the conveying frame 1.

[0067] The cathode wire 7 in this embodiment is a stainless steel sheet with a relatively thin thickness. In order to prevent the cathode wire 7 between two adjacent driving nodes from sagging, a supporting node can be set between the two adjacent driving nodes to better support the cathode wire 7; illustratively, the supporting node includes a frame 1321 and a number of supporting rollers (the frame 1321 and the supporting rollers are not shown in the figure) respectively arranged on the upper and lower sides of the cathode wire 7, and a certain number of supporting rollers are rotatably mounted on each frame 1321. The frame 1321 is also fixedly mounted on the conveying frame 1, and the supporting rollers on the upper and lower sides of the cathode wire 7 are all in contact with the upper and lower surfaces of the cathode wire 7; in the X direction, multiple supporting nodes are set to achieve better support for the cathode wire 7 moving on the conveying frame 1, so as to prevent the cathode wire 7 from sagging and affecting the subsequent cutting and bending processes.

[0068] In this embodiment, in order to ensure that the cathode wire 7 moving on the conveyor frame 1 does not deviate, Figure 1 As shown, a plurality of limiting rollers 131 are provided on both sides of the conveyor frame 1 along the Y direction, and the plurality of limiting rollers 131 are arranged on the conveyor frame 1 at intervals along the X direction. The limiting rollers 131 are rotatably mounted on the conveyor frame 1 and the limiting rollers 131 at least partially protrude from the conveyor frame 1, as shown in FIG. Figure 4 、 Figure 5 As shown, the circumferential side of the limiting roller 131 abuts against the edge positions of both sides of the cathode wire 7, thereby limiting and constraining the moving path of the cathode wire 7 and preventing the cathode wire 7 from deviating when moving on the conveyor frame 1.

[0069] like Figure 1 、 Figure 2As shown, a cutting assembly 2 is provided in this embodiment, wherein the cutting assembly 2 is connected to the conveyor frame 1 along the X direction, and the cutting assembly 2 is used to cut the cathode line 7 and form a plurality of slits 73 (such as Figure 6 As shown in FIG, wherein the slit 73 extends along the X direction and is arranged at a preset angle to the X direction, and the slit 73 passes through the edge of the cathode wire 7 on the side close to the discharge end 12, so as to form a cutting opening at the edge of the cathode wire 7 that is connected to the outside world; the formation of the slit 73 divides the cathode wire 7 into a main body portion 71 and a bent portion 72, as shown in FIG. Figure 6 As shown, due to the existence of the slit 73, the bent portion 72 only passes through the connecting portion 74 ( Figure 6 The dotted line in the figure indicates the connection between the bending portion 72 and the main body 71, that is, the connection portion 74 is connected to the main body 71; in this embodiment, when the cathode wire 7 is cut, the cathode wire 7 moves at a set speed under the action of the driving component 132, and the cutting component 2 cuts the cathode wire 7 moving at the set speed and forms the above-mentioned slit 73 on the cathode wire 7; since the cutting process is carried out during the movement of the cathode wire 7, the moving speed of the cutting component 2 must be greater than the moving speed of the cathode wire 7 when cutting, so that the above-mentioned slit 73 can be cut on the cathode wire 7; after the cutting component 2 cuts the slit 73 of a predetermined length, the cutting component 2 quickly returns in the opposite direction in the X direction to cut the cathode wire 7 behind the slit 73 again, thereby achieving A plurality of spaced slits 73 are cut on the cathode wire 7; in this embodiment, the distance S between two adjacent slits 73 determines the density of the discharge tips on the cathode wire 7 (the smaller S is, the greater the density of the discharge tips is; vice versa); the discharge tips on the cathode wire 7 can significantly reduce the corona inception voltage, making it easier for the electric field to produce corona discharge, and the electric field strength is highly concentrated at the tip, thereby making it easier to ionize the air, generating a large number of free electrons and ions, and achieving a better dust removal effect; in this embodiment, the distance between two adjacent slits 73 can be set according to the actual usage needs of the user; the size of the distance S between two adjacent slits 73 is determined by the speed at which the drive component 132 drives the cathode wire 7 to move on the conveyor frame 1 and the speed at which the cutting component 2 moves back relative to the conveyor frame 1.

[0070] like Figure 3As shown, this embodiment provides a bending component 3, wherein the bending component 3 is arranged on the conveyor frame 1 between the cutting component 2 and the discharge end 12, and the bending component 3 is used to bend the bending portion 72 formed by cutting so that the bending portion 72 and the main body 71 are bent at a preset angle; since the slit 73 passes through the edge position of the cathode line 7 on the side toward the discharge end 12, when the bending portion 72 moves to the position of the bending component 3, the bending component 3 applies an upward or downward force to the bending portion 72, so that the bending portion 72 can bend relative to the main body 71 when the force is applied, wherein the bending portion is at the connection between the bending portion 72 and the main body 71 (that is, the connection portion 74), so that the bending portion 72 is bent at a preset angle relative to the main body 71, and at this time, the bending portion 72 at the preset angle with the main body 71 constitutes the discharge tip of the cathode line 7 (as shown in FIG. Figure 15 As shown); For example, in this embodiment, the angle between the bending portion 72 and the main body 71 can be 30°, 40°, 50° or 60°, or any angle value between 30° and 60°. In this embodiment, there is no limitation on the preset angle between the bending portion 72 and the main body 71. In actual production, the above-mentioned bending angle can be set accordingly according to user requirements.

[0071] For example, in order to further improve the electrostatic precipitator effect of the produced cathode wire 7 (increase the density of the discharge tips on the cathode wire 7), the above-mentioned slits 73 can be cut on both sides of the cathode wire 7 along the Y direction, and in the X direction, the slits 73 on both sides of the cathode wire 7 are staggered (e.g. Figure 4 As shown in FIG, the slits 73 on the opposite side penetrate the edge of the cathode wire 7 toward the discharge end 12. The reason why the slits 73 on both sides are staggered in the X direction is, on the one hand, to make the distribution of the discharge tips on the cathode wire 7 more uniform, so as to improve the electrostatic precipitator effect on the gas flowing through. On the other hand, when the bent portion 72 is bent at a preset angle relative to the main body 71, a notch will be formed at the original position of the bent portion 72. If the slits 73 on both sides are not staggered in the X direction, then when the bent portion 72 is bent at a preset angle relative to the main body 71, two notches will be formed at the same position on the cathode wire 7 along the Y direction, which will easily lead to a reduction in the structural strength of the cathode wire 7, which is not conducive to its stability in use.

[0072] In this embodiment, it is necessary to set up a matching cutting assembly 2 and bending assembly 3 on the other side of the conveyor frame 1 along the Y direction, and the working process of the cutting assembly 2 and the bending assembly 3 is the same as above, that is, the cutting assembly 2 and the bending assembly 3 on both sides of the conveyor frame 1 along the Y direction work simultaneously, and are used to cut the above-mentioned slits 73 on both sides of the cathode line 7 along the Y direction, and form bending portions 72 on both sides of the cathode line 7 along the Y direction. When the above-mentioned bending portion 72 is bent at a preset angle with the main body 71 under the action of the bending assembly 3, the discharge tip distribution density on the cathode line 7 is greater (such as Figure 15 As shown), the electrostatic precipitator effect of the cathode line 7 can be further improved; for example, the bent portions 72 distributed on both sides of the cathode line 7 along the Y direction can be arranged in opposite directions, such as Figure 13 、 Figure 14 As shown: the plurality of bending portions 72 on the same side can be bent downward, and the plurality of bending portions 72 on the other side can be bent upward, thereby obtaining Figure 15 In the cathode wire 7 structure shown in FIG, discharge tips formed by bends 72 are distributed on both sides of the cathode wire 7 to improve the uniformity of the corona discharge of the cathode wire 7. For example, when the discharge tips (such as thorns) on the cathode wire 7 are evenly arranged, corona discharge occurs simultaneously at multiple tips rather than being concentrated in a single area. This evenly distributed discharge ensures that ionized gas (such as ions and free electrons) is uniformly generated across the entire electrode surface. The evenly distributed corona discharge can more effectively cover the entire cross-section of the gas flowing through it, allowing particles or molecules in the gas to interact more evenly with the ionized gas. The evenly distributed corona discharge ensures that dust particles are effectively charged throughout the gas flow path, thereby improving dust removal efficiency.

[0073] For example, when the bent portions 72 are provided on both sides of the cathode line 7 along the Y direction and are bent relative to the main body 71 to a preset angle to form a discharge tip, the driving component 132 needs to be centered relative to the cathode line 7, such as Figure 4 As shown, the bent portion 72, which is at a preset angle to the main body 71, will not touch the driving assembly 132 during the movement of the cathode line 7; the upper frame 1321 is connected to the fixed rod on one side along the Y direction (so that the setting of the fixed rod will not affect the upward bent portion 72 moving along the cathode line 7), and is fixedly installed on the conveying frame 1 via the fixed rod, and the lower frame 1321 is connected to the fixed rod on the other side along the Y direction (so that the setting of the fixed rod will not affect the downward bent portion 72 moving along the cathode line 7), and is fixedly installed on the conveying frame 1 via the fixed rod.

[0074] Reference Figure 2 、 Figure 5 、 Figure 6As shown, in one embodiment of the present application, the cutting assembly 2 includes a guide rail 21, which is provided on the conveying frame 1, wherein the guide rail 21 includes a slide bar 212 fixedly mounted on the conveying frame 1, and a screw 211 rotatably mounted on the conveying frame 1, the screw 211 and the slide bar 212 both extend along the X direction and are spaced apart in the Y direction, wherein the screw 211 is driven by a cutting motor 26 fixed to the conveying frame 1; a moving member 22 is connected to the guide rail 21 for movement along the X direction, and two sliding holes are provided on the moving member 22 along the X direction, one of the sliding holes being connected to the guide rail 21. The slide rod 212 is slidably assembled, and an internal thread is provided in the other slide hole and is threadably assembled with the screw rod 211. The cutting motor 26 is started to drive the screw rod 211 to rotate, thereby driving the movable member 22 to move in the X direction relative to the conveying frame 1; the cutting part 23 moves along the Y direction and is connected to the movable member 22. When the cutting motor 26 drives the movable member 22 to move along the X direction, the cutting part 23 moves synchronously along the Y direction, thereby realizing cutting to form the above-mentioned slit 73 on the cathode line 7, and dividing the cathode line 7 into a main body 71 and a bending part 72.

[0075] In this embodiment, when the cutting motor 26 drives the moving part 22 to move along the X direction from the feed end 11 to the discharge end 12 through the screw 211, it is necessary to ensure that the moving speed of the moving part 22 is greater than the moving speed of the cathode line 7, so that the above-mentioned slit 73 can be formed by cutting on the cathode line 7; when the moving speed of the moving part 22 along the X direction is fixed, the greater the moving speed of the cutting part 23 along the Y direction, the smaller the length of the slit 73, and vice versa; the specific parameters of the slit 73 can be set according to the actual needs of the user in the actual production process.

[0076] In this embodiment, when the slit 73 completely penetrates the edge position of one side of the cathode line 7 toward the side of the discharge end 12, the cutting motor 26 needs to rotate in the opposite direction and drive the moving part 22 to quickly return to the initial position through the screw 211, so as to cut the upper and lower parts of the cathode line 7 and form a preset slit 73; in this embodiment, during actual production, the length of the slit 73 is determined, and the moving speed of the conveying component 13 driving the cathode line 7 is determined. In order to achieve the preset slit 73 on the cathode line 7, the distance that the cutting motor 26 drives the moving part 22 to move along the X direction is also determined; in order to achieve automated control, the cutting motor 26 can be connected to a central controller, and the central controller can be used to control the movement of the cathode line 7. The device controls the rotation angle and rotation direction of the cutting motor 26; illustratively, the central controller controls the cutting motor 26 to start up at a preset time, and the cutting of the slit 73 is just completed, and the moving part 22 is controlled to drive the cutting part 23 to quickly return to the initial position in the opposite direction (the cutting motor 26 stops working), and waits for the start-up instruction of the central controller to cut the next part of the cathode line 7. Because the moving speed of the cathode line 7 is known, the central controller coordinates and calculates the time required for the moving part 22 to return to the initial position and the distance the cathode line 7 advances during this time period, and accordingly controls the working time node for starting the cutting motor 26 again to achieve cutting of equidistantly spaced slits 73 on the cathode line 7.

[0077] Reference Figure 2 、 Figure 5 、 Figure 6 As shown, in one embodiment of the present application, the cutting assembly 2 further includes a guide rod 24 fixed to the guide rail 21, the guide rod 24 extending along the X direction and being arranged at a preset angle with the X direction. In this embodiment, the speed of movement of the cutting portion 23 along the Y direction depends on the size of the inclination angle between the guide rod 24 and the X direction. The larger the inclination angle of the guide rod 24, the greater the speed of movement of the cutting portion 23 relative to the moving member 22 along the Y direction when the moving member 22 moves along the X direction; conversely, the smaller the speed. Figure 2 As shown, a slide groove extending along the Y direction is provided on the movable member 22, and a part of the cutting portion 23 is slidably assembled in the slide groove, and a first elastic member 25 (a spring) is provided between the cutting portion 23 and the movable member 22. The first elastic member 25 is provided in the slide groove, one end of which is connected to the cutting portion 23 and the other end is connected to the slide groove wall; wherein the guide rod 24 is provided on the side of the cutting portion 23 away from the cathode line 7, and the cutting portion 23 is always tightly attached to the side wall of the guide rod 24 under the elastic force of the first elastic member 25 (the first elastic member 25 is in a stretched state and always provides the cutting portion 23 with a force to move in the direction away from the cathode line 7).

[0078] In this embodiment, when the cutting motor 26 drives the screw 211 to rotate and drives the moving member 22 to move at a preset speed, the cutting portion 23 is synchronously driven to move along the X direction at a preset speed. In the process of moving along the X direction, the first elastic member 25 synchronously drives the cutting portion 23 to move relative to the moving member 22 along the Y direction, so that the cutting portion 23 always abuts against the side wall of the guide rod 24; Figure 6 As shown, when the movable member 22 moves to the preset position along the X direction, the cutting portion 23 also moves synchronously to the preset position along the Y direction relative to the movable member 22 under the action of the first elastic member 25 (at this time, the first elastic member 25 is stretched to the minimum). At this time, the slit 73 cut by the cutting portion 23 on the cathode line 7 completely penetrates the edge position of the cathode line 7 on one side along the Y direction. At this time, the central controller controls the cutting portion 23 to stop cutting, and controls the cutting motor 26 to rotate in the opposite direction to drive the movable member 22 and the cutting portion 23 to quickly return to the initial position. When the movable member 22 returns in the opposite direction, the cutting portion 23 moves synchronously relative to the movable member 22 under the action of the first elastic member 25 (so that the stretching amount of the first elastic member 25 gradually increases), so as to move to the initial position (the cutting motor 26 stops working) and waits for the start-up instruction of the central controller to cut the upper and lower parts of the cathode line 7.

[0079] Reference Figure 2 As shown, in one embodiment of the present application, the cutting portion 23 includes a cutting head 231 and a mounting frame 232, wherein the mounting frame 232 is connected to the moving member 22 along the Y direction, and the cutting head 231 is provided on the mounting frame 232, and the cutting head 231 is used to cut the cathode line 7 and form the above-mentioned slit 73; the first elastic member 25 is connected between the mounting frame 232 and the moving member 22; illustratively, the cutting head 231 in this solution can be a laser emitter (using a high-energy-density laser beam to irradiate the surface of the material, so that the material quickly absorbs the laser energy and converts it into heat energy, thereby achieving melting, vaporization or combustion of the material , and eventually form an incision) or an arc emitter (a processing method that uses a high-temperature electric arc to heat the metal, melt it and blow it off to form an incision); when a laser emitter is selected for cutting, the power of the laser emitter is controlled, and then the energy of the emitted laser beam is controlled, so as to achieve cutting of the cathode line 7; when an arc emitter is selected for cutting, the working power of the arc emitter is controlled, and then the temperature generated by the arc is controlled, and it is used to cut the cathode line 7; since the above two cutting methods are conventional cutting methods in the prior art, their working principles will not be explained in detail.

[0080] In this embodiment, since the side of the mounting bracket 232 facing away from the cathode line 7 is always tightly abutted against the side wall of the guide rod 24 under the action of the first elastic member 25, in order to enable the mounting bracket 232 to move more smoothly along the side wall surface of the guide rod 24 when the movable member 22 moves along the X direction, this embodiment provides a structure that enables the mounting bracket 232 to move more smoothly when it abuts against the side wall surface of the guide rod 24 under the action of the first elastic member 25; for example, a groove can be provided on the side of the mounting bracket 232 facing the guide rod 24, and a member can be rotatably installed in the groove. The rotating column 2322, the peripheral side wall of the rotating column 2322 and the side wall of the guide rod 24 are in contact with each other. When the movable frame moves along the X direction, the mounting frame 232 is synchronously driven to move along the X direction and close to the side wall of the guide rod 24, so that the contact between the mounting frame 232 and the side wall of the guide rod 24 is transformed from the original sliding contact to rolling contact, thereby improving the sensitivity of the mounting frame 232 when moving along the side wall of the guide rod 24; in order to further improve the above effect, the rotating column 2322 can be rotatably installed in the above groove via a bearing, and the setting of the bearing can make the rotation of the rotating column 2322 smoother.

[0081] Reference Figure 2 、 Figure 5 、 Figure 6 As shown, in one embodiment of the present application, the mounting frame 232 has a telescopic rod 2321 that can be extended and retracted along the Y direction, wherein the telescopic rod 2321 can be an electrically adjustable rod, and the cutting head 231 is fixedly connected to the retractable end of the telescopic rod 2321; Figure 5 As shown, the guide rod 24 includes a first rod 241 and a second rod 242 connected to each other, wherein the first rod 241 extends along the X direction, and the second rod 242 is set at a preset angle to the X direction. In order to ensure that the first rod 241 and the second rod 242 can maintain a smooth transition at the connection point, the guide rod 24 in this solution is preferably set as an integral whole.

[0082] In this embodiment, the cutting head 231 has a first working mode and a second working mode. Figure 6 As shown, when the cutting head 231 moves closely against the side wall of the second rod 242, the cutting head 231 is in the second working mode, for cutting the cathode wire 7 and forming the above-mentioned slit 73 passing through one side of the edge of the cathode wire 7; Figure 5 As shown, when the cutting head 231 moves close to the side wall of the first rod 241, the cutting head 231 is in the first working mode. At this time, the cutting head 231 is used to cut the connection between the bending portion 72 and the main body 71 ( Figure 6In order to facilitate the control of the working mode of the cutting head 231 and switch it between different working modes, the cutting head 231 and the supporting auxiliary equipment connected thereto can be connected to the central controller, and the working mode of the cutting head 231 is controlled by the central controller.

[0083] In this embodiment, when the cutting head 231 is in the first working mode, the cutting head 231 is controlled to work at a preset power. At this time, the working power of the cutting head 231 is relatively low, and it is only used to preheat the connection between the bending portion 72 and the main body 71 (connecting portion 74), and does not cut it. The role of preheating is to facilitate the subsequent bending component 3 to bend the bending portion 72, because when the connecting portion 74 is heated to a certain temperature, the physical properties of the connecting portion 74 will change, for example: the yield strength of the connecting portion 74 is reduced, so that it is easier to greatly increase the stress level required for plastic deformation. At the same time, preheating can increase the plasticity of stainless steel, making it less likely to break or crack during the bending process; in addition, preheating can significantly reduce the force required for bending, thereby reducing the bending force requirements applied to the bending component 3; further preheating can cause the bending portion 72 to rebound after bending, making the angle after bending more stable.

[0084] In this embodiment, when the cutting head 231 is in the first working mode, the cutting motor 26 drives the cutting head 231 through the screw 211 to move along the X direction at a speed V1 that is consistent with the moving speed V of the cathode line 7. At the same time, the telescopic rod 2321 synchronously drives the cutting head 231 to move in the Y direction (during this process, the telescopic rod 2321 extends), thereby achieving the connection between the bending portion 72 and the main body 71, as shown in FIG. Figure 6 The position shown by the dotted line is preheated; in order to facilitate the control of the telescopic rod 2321, the telescopic rod 2321 can be electrically connected to the central controller, and the telescopic action of the telescopic rod 2321 is controlled by the central controller.

[0085] In this embodiment, when the moving frame drives the cutting head 231 to move to the connection between the first rod 241 and the second rod 242 (such as Figure 5 As shown in the partially enlarged view in the figure), at this time, the central controller adjusts the running speed of the cutting motor 26, and drives the moving member 22 to move at a faster speed along the X direction through the screw 211, so that a difference is generated between the speeds of the moving member 22 and the cathode line 7 along the X direction, that is, V1 is greater than V; thereby, when the moving member 22 drives the cutting head 231 and makes the cutting head 231 move close to the side wall of the second rod 242, the cutting head 231 can be synchronously moved in the Y direction under the action of the first elastic member 25, so that when the cutting head 231 moves to the preset position along the second rod 242 (as shown in the figure), ... Figure 6), at this time, the cutting head 231 cuts a slit 73 on the cathode line 7 that passes through the cathode line 7 along the Y direction; then the central controller controls the cutting head 231 to stop working, and synchronously adjusts the rotation direction of the cutting motor 26, and synchronously controls the telescopic rod 2321 to retract to the initial position; thereby, the cutting motor 26 drives the moving part 22 to quickly turn back in the opposite direction and move to the initial position (as shown in FIG. Figure 5 ), at this time, the movable member 22 is at the end of the first rod 241 away from the second rod 242, the telescopic rod 2321 is in a retracted state, and the position directly below the cutting head 231 corresponds exactly to the edge position of the cathode line 7; at this time, the cutting motor 26, the cutting head 231, and the telescopic rod 2321 are waiting for the central controller to issue another instruction for cutting the upper and lower parts of the cathode line 7 and forming the above-mentioned slit 73.

[0086] For example, in this embodiment, when the central controller controls the cutting motor 26 to start working again and drives the movable part 22 to move along the X direction, the central controller synchronously controls the cutting head 231 to start and controls the telescopic rod 2321 to extend; during the startup process, the cutting head 231 can reach the preset power and the temperature when it can cut the stainless steel sheet, which requires a certain amount of time, for example: fiber laser: from the beginning of preheating to reaching stable output, it takes 1-5 seconds to achieve the predetermined required output power; that is to say, it takes several seconds for the cutting head 231 to reach the preset power from startup (during this period, the temperature generated by the cutting head 231 cannot be used to cut the stainless steel sheet). In this embodiment, the time required for the above-mentioned cutting head 231 to start and reach the preset power can be used to preheat the connection between the bending portion 72 and the main body 71; set the motor 26 to drive the movable part 22 to move to the first rod 241 and When the second rod 242 is connected, the cutting power of the cutting head 231 reaches the preset value, and the cathode line 7 can be cut; in the above process, according to the type of cutting head 231 selected (the time required from starting to finally reaching the preset cutting power is known), the central controller controls the extension and retraction rate of the telescopic rod 2321 according to the above time, and tries to make the cutting head 231 move to the preset position along the Y direction under the drive of the telescopic rod 2321 before the cutting power of the cutting head 231 reaches the preset power, thereby completing the preheating of the connection between the bending part 72 and the main body 71 (that is, the connection part 74), so as to avoid the cutting head 231 not moving to the preset position under the drive of the telescopic rod 2321 when the cutting power of the cutting head 231 reaches the preset cutting power, thereby cutting the part of the connection between the bending part 72 and the main body 71 (causing unnecessary cutting and affecting the connection strength between the bending part 72 and the main body 71).

[0087] In this embodiment, the preheating between the bending portion 72 and the main body 71 can be carried out in the above two ways: first, when the cutting head 231 moves along the first rod 241, the central controller controls the cutting head 231 to operate at a lower power to preheat the connecting portion 74; but when the cutting head 231 needs to cut the cathode line 7, the central controller also needs to control the cutting head 231 to increase the operating power, and only when the preset cutting power is reached can the cathode line 7 be cut. During this period, it is necessary to wait for a certain period of time (although this time is short, each cutting process has to wait for this short time, and a large number of these short times are superimposed together, resulting in a significant increase in the final wasted time, which is not conducive to improving cutting efficiency). Second, when the cutting head 231 moves along the first rod 241, the central controller controls the cutting head 231 to operate at a lower power to preheat the connecting portion 74; but when the cutting head 231 needs to cut the cathode line 7, the central controller also needs to control the cutting head 231 to increase the operating power, and only when the preset cutting power is reached can the cathode line 7 be cut. During this period, it is necessary to wait for a certain period of time (although this time is short, each cutting process has to wait for this short time, and a large number of these short times are superimposed together, resulting in a significant increase in the final wasted time, which is not conducive to improving cutting efficiency). When the cutting head 231 is in operation, the central controller controls the cutting head 231 to start and directly approaches the preset cutting power. Before the operating power of the cutting head 231 reaches the stable preset power, the heat generated by the cutting head 231 (this heat cannot be used to cut stainless steel sheets) is used to preheat the connection between the bending portion 72 and the main body 71, which saves the time required for the cutting head 231 to reach the preset stable cutting power. At the same time, the heat generated before the cutting head 231 reaches the preset cutting power is also used to preheat the connection between the bending portion 72 and the main body 71, thereby improving the cutting efficiency and reducing the waste of energy. Preferably, the second method is selected in this embodiment to preheat the connection between the bending portion 72 and the main body 71 (that is, the connection portion 74).

[0088] Reference Figure 3 、 Figure 7 As shown, in one embodiment of the present application, the bending assembly 3 includes a bending rod 31 rotatably mounted on the conveying frame 1 and the rotation axis of the bending rod 31 extends along the Y direction, and the bending rod 31 has a standby position and a bending position; and a connecting rod 32, the connecting rod 32 extends along the Y direction, and the end of the connecting rod 32 away from the cathode line 7 is fixedly connected to the free rotation end of the bending rod 31; a pressing member 33 is connected to the end of the connecting rod 32 away from the bending rod 31; when the bending rod 31 is in the standby position, the pressing member 33 is separated from the cathode line 7, that is, when the bending rod 31 is in the standby position, the pressing member 33 is separated from the cathode line 7. The pressing member 33 is below the cathode line 7 (not in contact with the lower surface of the cathode line 7) or the pressing member 33 is above the cathode line 7 (not in contact with the upper surface of the cathode line 7); in this embodiment, the bending directions of the several bending portions 72 on both sides of the cathode line 7 along the Y direction are arranged in opposite directions. Therefore, the pressing member 33 on one side of the cathode line 7 is below the cathode line 7 and does not contact the lower surface of the cathode line 7 when it is in the standby position; the pressing member 33 on the opposite side is above the cathode line 7 and does not contact the upper surface of the cathode line 7 when it is in the standby position.

[0089] The cathode wire 7 is conveyed by the conveying assembly 13, so that when the bent portion 72 moves to a position corresponding to the pressing member 33, as shown in FIG. Figure 3 As shown, the bending rod 31 on the cathode line 7 along the Y direction rotates upward, and drives the pressing member 33 to contact the lower surface of the bending portion 72 and push the bending portion 72 to bend upward relative to the main body 71; at the same time, the bending rod 31 on the opposite side rotates downward, and drives the pressing member 33 to contact the upper surface of the bending portion 72 and push the bending portion 72 to bend downward relative to the main body 71 (as shown in FIG. Figure 7 as shown); Figure 10 As shown, this embodiment takes the bending process of the bending portion 72 on one side of the cathode line 7 along the Y direction as an example to describe: when the bending portion 72 moves with the cathode line 7 to a suitable position above the pressing member 33, the bending rod 31 is controlled to rotate upward, and then the pressing member 33 is driven upward to abut against the lower surface of the bending portion 72 through the connecting rod 32. As the bending rod 31 continues to rotate upward, the pressing member 33 forces the bending portion 72 to bend relative to the main body 71. At this time, the connection between the bending portion 72 and the main body 71 (that is, the connecting portion 74) is bent; so that when the bending rod 31 rotates to a preset bending position (at this time, the bending portion 72 is bent relative to the main body 71 to a preset clamping position) The bending rod 31 is controlled to rotate rapidly in the opposite direction so that the bending rod 31 drives the pressure piece 33 to quickly return to the initial standby position, so as not to hinder the cathode wire 7 from moving toward the discharge end 12 along with the conveying assembly 13; after the bending rod 31 drives the pressure piece 33 to move to the standby position, it continues to wait for the bending portion 72 at the rear, and when the bending portion 72 at the rear moves to a suitable position above the pressure piece 33 again, the bending rod 31 is controlled to rotate upward again, thereby realizing the bending process of the bending portion 72; in the above-mentioned bending process of the bending portion 72, the cathode wire 7 does not need to stop, so that the cathode wire 7 completes the bending process during the movement on the conveying frame 1, thereby improving the bending efficiency.

[0090] In this embodiment, if Figure 10 As shown, since the bending rod 31 drives the pressing member 33 to rotate upward, the cathode line 7 always moves toward the discharge end 12 along the X direction at a predetermined speed; Figure 16As shown, assuming that the bending rod 31 remains at the angle a shown in the figure, the cathode wire 7 moves from the feed end 11 to the discharge end 12 along the X direction under the conveying action of the conveying assembly 13, which will also further increase the bending angle of the bending portion 72 relative to the main body 71 (that is, the effect of bending the bending portion 72 relative to the main body 71 is achieved). Therefore, when the bending rod 31 remains stationary, the cathode wire 7 will also force the bending portion 72 to bend relative to the main body 71 toward the discharge end 12. In this embodiment, the bending of the bending portion 72 relative to the main body 71 is caused by Two processes are implemented together: one is that the cathode wire 7 moves along the X direction toward the discharge end 12, and the other is that the bending rod 31 drives the pressure piece 33 to rotate upward and forces the bending portion 72 to bend relative to the main body 71; therefore, when the bending portion 72 is bent to a preset angle relative to the main body 71, since the cathode wire 7 in this solution always moves toward the discharge end 12 at a certain speed, the bending rod 31 only needs to rotate a smaller angle (compared to the cathode wire 7 being stationary) to achieve the bending portion 72 being bent to the preset angle relative to the main body 71, so that the bending efficiency is improved.

[0091] Reference Figure 11 、 Figure 12 As shown, in one embodiment of the present application, in order to allow the pressing member 33 and the bent portion 72 to have a larger contact area, the pressing member 33 is configured as a flat plate in this embodiment, such as Figure 11 As shown, there is a large contact area between the pressure piece 33 and the bending portion 72, so that when the bending rod 31 drives the pressure piece 33 to force the bending portion 72 to bend relative to the main body 71, the interaction force generated between the bending portion 72 and the pressure piece 33 can be more evenly distributed on the bending portion 72, so as to prevent the interaction force between the two from being excessively concentrated in a small area, resulting in the bending portion 72 and the pressure piece 33 causing the contact part of the bending portion 72 and the pressure piece 33 to produce yield deformation due to the relatively concentrated stress in the process of driving the bending portion 72 to bend relative to the main body 71 (causing unnecessary bending deformation of the bending portion 72 body), affecting the final bending angle of the bending portion 72 relative to the main body 71. At the same time, the bending deformation of the bending portion 72 will cause the shape of the discharge tip to change, thereby changing the distribution of the local electric field, making the corona discharge uneven, and reducing the efficiency of the electrostatic precipitator.

[0092] In this embodiment, when the bending rod 31 drives the pressure piece 33 to rotate upward, the cathode wire 7 simultaneously moves toward the discharge end 12, so that the contact position between the pressure piece 33 and the lower surface of the bending portion 72 also changes, so that the force of the pressure piece 33 acting on the bending portion 72 can be applied to different regional positions in succession, further reducing the probability of stress concentration at a certain part of the bending portion 72, resulting in yield bending deformation in a partial area of ​​the bending portion 72.

[0093] In this embodiment, the contact position of the pressing member 33 relative to the bent portion 72 will change. Therefore, in order to ensure that the flat pressing member 33 can always fit the surface of the bent portion 72 during the entire bending process, the pressing member 33 and the connecting rod 32 are rotatably mounted and the rotation axis of the pressing member 33 extends along the Y direction. Figure 12 As shown, a hole is provided in the pressing piece 33 for partially inserting the connecting rod 32, and one end of the connecting rod 32 is rotatably installed in the hole, and the connecting rod 32 is inserted into the hole and one end is stepped, and a torsion spring 34 is sleeved on the connecting rod 32 with a thinner diameter, one end of the torsion spring 34 is fixed on the pressing piece 33, and the other end is fixed on the connecting rod 32; therefore, when the bending rod 31 drives the pressing piece 33 to press against the surface of the bent portion 72, with the rotation of the bending rod 31 and the movement of the cathode wire 7, the pressing piece 33 can rotate relative to the connecting rod 32, so that the pressing piece 33 always maintains a close contact with the bent portion 72, and the torsion spring 34 continuously stores energy at this time; when the bending rod 31 rotates to the preset bending position, and controls the bending rod 31 to rotate rapidly in the opposite direction and perform rapid During the folding process, the pressure piece 33 returns to its original position synchronously and quickly under the action of the torsion spring 34, so that when the bending rod 31 rotates to the standby position, the position angle of the pressure piece 33 relative to the connecting rod 32 also synchronously returns to its initial state; in this embodiment, when the bending rod 31 is set to the standby position, the relative position angle relationship between the pressure piece 33 and the connecting rod 32 under the action of the torsion spring 34 satisfies: when the bending portion 72 moves to a suitable position above the pressure piece 33 along with the cathode line 7, the bending rod 31 is controlled to rotate upward, so that when the pressure piece 33 contacts the lower surface of the bending portion 72, the pressure piece 33 can just be in complete contact with the lower surface of the bending portion 72, thereby achieving the maximum contact area between the pressure piece 33 and the bending portion 72, and avoiding stress concentration as much as possible.

[0094] Reference Figure 8 、 Figure 9 、 Figure 11As shown, in one embodiment of the present application, the electrostatic precipitator cathode wire production device further includes a pressing component 4 and a pushing component 5; wherein the pressing component 4 is connected to the conveying frame 1 along the Z direction, and the pressing component 4 is elastically connected to the conveying frame 1, and the pressing component 4 has a pressing portion 41 pressed against the surface of the cathode wire 7, and the pressing portion 41 can rotate relative to the pressing component 4; the pressing component 4 also includes a pressing frame 42, and a sliding cavity 14 extending along the Z direction is provided on the conveying frame 1, and a portion of the pressing frame 42 is slidably assembled in the sliding cavity 14 along the Z direction (the pressing frame 42 is located in the sliding cavity 14 A spring is provided between the lower end surface of the inner part and the bottom of the sliding cavity 14), a pressure shaft 421 extending along the Y direction is rotatably mounted on the pressure frame 42, and the pressure portion 41 is coaxially sleeved on the pressure shaft 421, so that the pressure portion 41 can rotate relative to the pressure frame 42. In this embodiment, the pressure portion 41 is a roller structure. For example, the roller structure can be set in a hollow shape, but it needs to have a certain structural strength; in the initial state, the pressure portion 41 and the surface of the cathode line 7 are in contact and matched (at this time, the force between the pressure portion 41 and the surface of the cathode line 7 is relatively small).

[0095] The pushing assembly 5 in this embodiment is connected to the conveyor frame 1 along the Z direction, wherein the pushing assembly 5 includes an active rod 52 and a passive rod 51, the active rod 52 and the passive rod 51 both extend along the Z direction and are spaced apart in the Y direction, the upper ends of the active rod 52 and the passive rod 51 are fixedly connected, the passive rod 51 is slidably assembled in the sliding cavity 14 along the Z direction, and a second elastic member 53 (such as Figure 11When the push assembly 5 is in the natural position, the second elastic member 53 connected between the passive rod 51 and the pressing frame 42 is compressed to a lesser extent; when the push assembly 5 is in the extrusion position, the second elastic member 53 connected between the passive rod 51 and the pressing frame 42 is compressed to a greater extent; when the bending portion 72 moves with the cathode line 7 to a suitable position above the pressing member 33, the bending rod 31 rotates from the standby position to the bending position, and at the same time, the push assembly 5 is controlled to move synchronously from the natural position to the extrusion position, that is, to drive the push assembly 5 (active rod 52, passive rod 51) to move downward and squeeze the second elastic member 53, so that the pushing force applied by the push assembly 5 is applied to the pressing frame 4 through the second elastic member 53. The cam 72 is bent relative to the main body 71 by the bending rod 31 through the pressing member 33, and the bending force applied by the pressing member 33 to the bending portion 72 causes the cathode wire 7 around the connection portion 74 to bend upwards (causing the cathode wire 7 as a whole to bend unnecessarily, thereby affecting the distribution of the electric field and thus affecting the electrostatic precipitator effect). In this embodiment, when the bending rod 31 drives the bending portion 72 to bend by the pressing member 33, the pushing member 5 simultaneously applies a pushing force to the pressing frame 42 and transmits the pushing force to the pressing portion 41, thereby pressing the area close to the connection portion 74 through the pressing portion 41, avoiding the area being subjected to the bending force applied by the bending rod 31 and being bent synchronously with the connection portion 74. Figure 8 As shown, when the bending rod 31 drives the bending portion 72 to bend from bottom to top, the pressing portion 41 should be located at the upper surface of the cathode line 7 to prevent the area close to the connecting portion 74 from being bent synchronously; the bending rod 31 on the other side of the cathode line 7 along the Y direction drives the bending portion 72 to bend from top to bottom, so the pressing portion 41 at this position should be located at the lower surface of the cathode line 7 (as shown in FIG. Figure 7 As shown in the figure, when the bending rod 31 drives the bending portion 72 to bend from top to bottom, the area of ​​the main body 71 around the connecting portion 74 is subjected to a downward bending force transmitted from the connecting portion 74. Therefore, the pressing portion 41 is arranged on the lower surface of the cathode line 7 and abuts against the surface of the cathode line 7, which can better avoid unnecessary bending deformation in areas other than the connecting portion 74.

[0096] In this embodiment, when the bending rod 31 rotates from the standby position to the bending position, and the bending portion 72 is bent to a preset angle relative to the main body 71, the bending rod 31 no longer applies a bending force to the bending portion 72, that is, the bending rod 31 drives the pressing member 33 to rotate from the bending position to the standby position. At the same time, the pushing assembly 5 also synchronously moves from the extrusion position to the natural position, which is used to remove the force applied to the pressing frame 42, so that the contact force between the pressing portion 41 and the surface of the cathode line 7 is reduced and restored to the initial level; the reason for this arrangement is that: when the contact force between the pressing portion 41 and the cathode line 7 When the relay force is large, the resistance to the movement of the cathode wire 7 is increased to a certain extent, so that the conveying component 13 needs to provide a larger conveying force to drive the cathode wire 7 to move on the conveying frame 1. When the bending portion 72 is bent to a preset angle relative to the main body 71, the main body 71 around the connecting portion 74 is no longer subjected to any bending force, so the contact force between the pressing portion 41 and the cathode wire 7 can be reduced, which is used to reduce the movement resistance of the cathode wire 7 on the conveying frame 1, thereby reducing the operating power required for the conveying component 13 to convey the cathode wire 7 to move, which helps to reduce energy consumption.

[0097] After the folding of the support frame 72 and the support frame 73 is in the state of being rotated, the folding member 72 of the support frame 73 is in the state of being rotated. When the pressing portion 41 is pressed, the bending rod 31 is controlled to move immediately and the bending portion 72 is bent; for example, the acquisition unit can be electrically connected to the central controller, and the central controller receives the movement position information of the bending portion 72 collected by the acquisition unit in real time, and controls the bending rod 31 to bend according to the movement position information of the bending portion 72; in this embodiment, the bending process of the bending portion 72 should be completed in the shortest possible time to prevent the connecting portion 74 from moving too far after passing the pressing portion 41, which will cause the pressing portion 41 to be unable to prevent the main body 71 around the connecting portion 74 from generating unnecessary bending deformation.

[0098] Reference Figure 7 、 Figure 8 、 Figure 11As shown, in one embodiment of the present application, the cathode wire production device of the electrostatic precipitator also includes a driving disk 6 rotatably mounted on the outer side wall of the conveying frame 1, and the driving disk 6 is driven by a driving motor 61 provided in the conveying frame 1 (the driving motor 61 is electrically connected to the central controller); in order to set the connecting rod 32 and the pressure piece 33, and enable them to rotate synchronously with the rotation of the bending rod 31, a disconnection point can be opened on both sides of the conveying frame 1 along the Y direction (the conveying frame 1 in this solution is fixedly installed on the ground or other platform in the workshop), which is used to accommodate the connecting rod 32 and synchronously drive the pressure piece 33 to rotate through the rotation of the bending rod 31, so as to bend the bending portion 72; the bending rod 31 extends radially along the driving disk 6 and the bending rod 31 is fixedly mounted on the peripheral side wall of the driving disk 6 at one end away from the connecting rod 32; as shown Figure 11 As shown, a push rod 54 extending radially along the driving disk 6 is fixedly connected to the peripheral side wall of the driving disk 6, and the push rod 54 and the bending rod 31 are connected to the peripheral side wall of the driving disk 6 at intervals. The push rod 54 is connected to the side of the pushing assembly 5 with an axle pin 55 extending along the Y direction, and a slide 521 matching the axle pin 55 is provided at the bottom of the active rod 52, so that the axle pin 55 can be movably assembled in the slide 521.

[0099] In this embodiment, when the bending rod 31 is in the standby position, the active rod 52 and the passive rod 51 are in the natural position under the action of the driving plate 6, the push rod 54 and the shaft pin 55. Figure 11As shown, when the driving disk 6 rotates in the counterclockwise direction, the bending rod 31 drives the pressure member 33 to bend the bending portion 72. At the same time, the active rod 52 is forced to move downward in the Z direction through the cooperation of the push rod 54, the shaft pin 55, and the slide 521, and the passive rod 51 of the synchronous belt moves downward in the slide cavity 14, compressing the second elastic member 53, thereby applying a certain amount of force downward to the pressure frame 42 through the second elastic member 53, and the force is finally applied to the cathode line 7 (that is, the main body 71 around the connecting portion 74) through the pressure portion 41 abutting against the surface of the cathode line 7. This force has the effect of preventing the main body 71 around the connecting portion 74 from bending upward, which is used to prevent the bending rod 31 from passing through the pressure member 3 When the bending portion 72 is forced to bend relative to the main body 71, the area of ​​the main body 71 around the connecting portion 74 is subjected to a large bending force, resulting in unnecessary bending deformation. After the bending portion 72 is bent to a preset angle relative to the main body 71, the driving disk 6 is controlled to rotate rapidly in the opposite direction, so that the bending rod 31 can quickly return to the standby position. During this process, the active rod 52 and the passive rod 51 of the belt are moved in the Z direction synchronously through the cooperation of the axial direction and the slideway 521, thereby removing the force applied to the pressing frame 42 (causing the pushing assembly 5 to return from the squeeze position to the natural position), thereby reducing the contact force between the pressing portion 41 and the surface of the cathode wire 7, thereby reducing the operating power required by the conveying assembly 13 to convey the cathode wire 7.

[0100] In this embodiment, the rotation angle, rotation direction, and speed of the drive motor 61 are controlled by a central controller, thereby achieving coordinated cooperation between the above-mentioned components (pushing assembly 5, pressing assembly 4, bending assembly 3), so that the bending process of the bending portion 72 and the pressing of the pressing portion 41 on the area around the connecting portion 74 are carried out simultaneously, so as to ensure high-quality bending of the bending portion 72 and form a discharge tip, thereby improving the electrostatic precipitator effect after the cathode line 7 is put into use.

[0101] In this embodiment, since the connection portion 74 is the connection portion 74 between the discharge tip (the bent portion 72 at a preset angle to the main body 71) and the main body 71, when the cutting head 231 preheats the connection portion 74, due to the high temperature at the connection portion 74, it is easy to cause an oxide layer to form on the surface of the connection portion 74. This is because the stainless steel sheet reacts chemically with the oxygen in the air at high temperature, and the oxide layer covering the surface of the connection portion 74 is insulating or weakly conductive, and its resistivity is much higher than that of the metal itself. When the oxide layer covers the connection portion 74 between the discharge tip and the main body 71, the contact resistance will be significantly increased; at the same time, the oxide layer will hinder the conduction and accumulation of electric charges, reduce the amount of ionized gas (ions and free electrons) generated, and thus affect the electrostatic precipitator effect.

[0102] like Figure 11 As shown, in this embodiment, in order to remove the oxide layer attached to the surface of the connecting portion 74, two rotatable scraping shafts 43 are respectively provided on the pressing frame 42 (the two scraping shafts 43 are arranged close to the pressing portion 41), and a scraping brush 44 is provided on the circumference of the scraping shaft 43 (the scraping brush 44 is composed of densely arranged thin iron wires). The two scraping shafts 43 are respectively located on the upper and lower sides of the cathode line 7, and the scraping brushes 44 are both in contact with the surface of the cathode line 7; the two scraping shafts 43 are connected to the pressing shaft 421 via a pulley set 45. When the pressing portion 41 is in contact with the surface of the cathode line 7, the cathode line 7 moves toward the discharge end 12 under the action of the conveying component 13, which will synchronize the belt's pressing The pressing part 41 rotates relative to the pressing frame 42, so that the pressing shaft 421 rotates synchronously with the two scraping shafts 43 through the pulley group 45. When the connecting part 74 moves to the position of the two scraping shafts 43 along with the cathode wire 7, the scraping brush 44 arranged on the side of the scraping shaft 43 scrapes and cleans the oxide layer attached to the upper and lower surfaces of the connecting part 74, so that the oxide layer attached to the surface of the connecting part 74 is separated from the main body 71 (after the cathode wire 7 is completely sent out from the discharge end 12, the cathode wire 7 is struck with a certain force, so that the oxide layer peeled off from the surface of the connecting part 74 can be shaken off from the cathode wire 7), so as to improve the electrostatic dust removal effect of the cathode wire 7 when in use.

[0103] In a second aspect, an embodiment of the present application provides a production method, which uses the electrostatic precipitator cathode wire production device in the above embodiment, including the following steps:

[0104] S1: First, the moving part 22 is driven to drive the cutting head 231 to move along the X direction at the same speed as the cathode line 7. At the same time, the telescopic rod 2321 is controlled to extend at a certain rate. At this time, the cutting head 231 is used to preheat the connection between the bending portion 72 and the main body 71, so as to facilitate the subsequent better bending processing of the bending portion 72 through the bending component 3.

[0105] S2: Then drive the moving part 22 to drive the cutting head 231 to move along the X direction at a speed greater than the moving speed of the cathode line 7. At this time, the cutting head 231 is used to cut the cathode line 7 and form a slit 73 on the cathode line 7. The slit 73 passes through the edge position of one side of the cathode line 7 along the Y direction toward the side of the discharge end 12.

[0106] S3: The central controller controls the driving disk 6 to drive the bending rod 31 to move from the standby position to the bending position, so as to bend the bending portion 72 relative to the main body 71 and form a preset angle; the driving disk 6 simultaneously drives the pushing assembly 5 to move from the natural position to the extrusion position, so that the pressing portion 41 is tightly pressed against the surface of the cathode line 7.

[0107] S4: When the bending portion 72 bends relative to the main body 71 and forms a preset angle, the central controller controls the driving disk 6 to rotate in the opposite direction, and drives the bending rod 31 to move from the bending position to the standby position and drives the pushing assembly 5 to move from the extrusion position to the natural position.

[0108] S5: Repeat the above steps S1 to S4 to form a plurality of bent portions 72 on the main body 71 at a preset angle to the main body 71 , thereby forming discharge tips of the cathode lines 7 .

[0109] In summary, the cathode wire production device in this solution cuts the cathode wire 7 through the cutting component 2 to form the main body 71 and the bending portion 72, and bends the bending portion 72 through the bending component 3 so that the bending portion 72 and the main body 71 form a preset angle, so that the bending portion 72 at the preset angle to the main body 71 constitutes a discharge tip; the cathode wire 7 of the electrostatic precipitator in this solution does not generate waste during the production process, avoids the need to set up additional collection equipment, and ensures the cleanliness of the work site; the cathode wire production device in this solution cuts the cathode wire 7 through the cutting component 2 , and the bending assembly 3 can quickly form a discharge tip (the bending portion 72 with a preset angle to the main body 71) on the cathode wire 7. Compared with the traditional method of welding the barb piece or the needle body to the surface of the metal tube, the production efficiency is significantly improved; and the tip used for discharge in the present solution is formed by directly bending the bending portion 72 relative to the main body 71. Compared with the traditional method of connecting two separate parts by welding, the connection between the bending portion 72 and the main body 71 in the present solution is more reliable and firm, and has higher stability in use.

[0110] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
