Description

Technical Field

[0001] The present invention relates to the technical field of electric dust removal cathode wire production equipment, and particularly to an electric dust collector 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 electric dust collectors; among them, flexible cathode wires are usually processed from stainless steel thin plates. During preparation, a serrated structure is processed on the stainless steel thin plate using a stamping die or a laser cutting device. During the punching process, a large amount of waste will be generated and scattered at the processing site. On the one hand, it affects the on-site working environment, and on the other hand, a separate collection device needs to be set up to collect and process the waste.

[0003] Rigid tubular cathode wires are usually made of metal tubes (stainless steel). During preparation, a large number of barbs or needle bodies are welded and fixed on the peripheral side wall of the metal tube in a staggered arrangement. In the above process, each barb or needle body is welded individually, and before welding, the barb or needle body needs to be adjusted to a predetermined placement position (so that the barb or needle body abuts against the outer peripheral wall of the metal tube), resulting in a low efficiency of the entire preparation process (unable to meet the large-scale production requirements); moreover, during long-term use, due to the fact that welding is prone to oxidation and some defects generated during the welding process (such as pores, slag inclusions), the corrosion resistance of the welded part is reduced. Over time, rust will occur at the welded part, which will weaken the structural strength of the welded part. Over time, the barb or needle 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 an urgent technical problem to be solved in the field of electric dust collector cathode wire production and processing. Summary of the Invention

[0005] The purpose of the present invention is to provide an electric dust collector cathode wire production device and a production method thereof, aiming to improve the problems of poor working environment and low production efficiency caused by waste generation and scattering at the site during the current cathode wire preparation process.

[0006] To achieve the above object, an embodiment of the present application provides an electric dust collector cathode wire production device, which has X, Y, and Z directions that intersect pairwise, and includes:

[0064] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. 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] Referring to Figures 1 - 15 As shown, in a first aspect, an apparatus for producing a cathode wire of an electrostatic precipitator is proposed in an embodiment of the present application, which has X, Y, and Z directions that intersect pairwise. The apparatus includes a conveying rack 1. The conveying rack 1 has a feeding end 11 and a discharging end 12 in the X direction. A conveying assembly 13 for driving the cathode wire 7 to move from the feeding end 11 to the discharging end 12 is provided on the conveying rack 1. The cathode wire 7 is driven to move on the conveying rack 1 through the conveying assembly 13. Exemplarily, a specific structure of the conveying assembly 13 is provided in this embodiment, such as Figure 13 , Figure 14 As shown, the conveying assembly 13 includes a plurality of driving assemblies 132 arranged in the X direction. The driving assembly 132 includes a frame body 1321 (one side of the frame body 1321 is fixedly installed on the conveying rack 1 through a fixing rod) and a driving roller group 1322. The driving roller group 1322 includes a plurality of driving rollers rotatably installed on the frame body 1321. A plurality of driving rollers located on the same frame body 1321 can be jointly driven by one motor; alternatively, each driving roller can provide driving force. For example, the driving roller can be selected as an in-built driving roller, that is, the driving motor assembly is built inside the roller body, so as to reduce the occupation of external space and improve the compactness and operation efficiency of the equipment. Preferably, in this embodiment, the driving roller is selected as an in-built driving roller to convey the cathode wire 7, which can preferably reduce the occupation of external space; such as Figure 13As shown in the figure, when the cathode wire 7 is conveyed, two driving components 132 cooperate with each other and are respectively located on the upper and lower sides of the cathode wire 7 (the two driving components 132 form a driving node), so that the driving roller sets 1322 mounted on the frame 1321 are in contact with the upper and lower surfaces of the cathode wire 7. When the driving rollers rotate, the cathode wire 7 can be synchronously driven to move on the conveying frame 1 (the rotation directions of the driving roller sets 1322 on the upper and lower sides of the cathode wire 7 are opposite), and move from the feeding end 11 to the discharging end 12; as Figure 4 shown, a plurality of cooperating driving components 132 can be arranged at intervals in the X direction for conveying the cathode wire 7; in this embodiment, the plurality of cooperating driving components 132 are used to drive the cathode wire 7 to move on the conveying frame 1 on the one hand, and on the other hand, they also achieve the effect of supporting the cathode wire 7, so that the cathode wire 7 can move on the conveying frame 1 from the feeding end 11 to the discharging end 12 under the clamping of the plurality of cooperating driving components 132; or a traction member is provided at the discharging end 12 for driving the cathode wire 7 to move on the conveying frame 1.

[0067] In this embodiment, the cathode wire 7 is a stainless steel thin plate 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 arranged between two adjacent driving nodes for better supporting the cathode wire 7; exemplarily, the supporting node includes frames 1321 respectively arranged on the upper and lower sides of the cathode wire 7 and a plurality of supporting rollers (the frames 1321 and the supporting rollers are not shown in the figure). A certain number of supporting rollers are rotatably installed on each frame 1321. The frames 1321 are also fixedly installed on the conveying frame 1, and the supporting rollers on the upper and lower sides of the cathode wire 7 are in contact with the upper and lower surfaces of the cathode wire 7; by arranging a plurality of supporting nodes in the X direction, it is used to better support the cathode wire 7 moving on the conveying frame 1 and 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 conveying frame 1 does not deviate, as Figure 1 shown, a plurality of limiting rollers 131 are respectively arranged on both sides of the conveying frame 1 along the Y direction. The plurality of limiting rollers 131 are arranged at intervals in the X direction on the conveying frame 1. The limiting rollers 131 are rotatably installed on the conveying frame 1 and at least part of the limiting rollers 131 protrude from the conveying frame 1, as Figure 4 、 Figure 5 shown, so that the circumferences of the limiting rollers 131 are in contact with the two side edge positions of the cathode wire 7, thereby realizing the limitation and constraint of the moving path of the cathode wire 7 and preventing the cathode wire 7 from deviating when moving on the conveying frame 1.

[0069] As Figure 1 、 Figure 2As shown, in this embodiment, a cutting assembly 2 is provided, wherein the cutting assembly 2 is movably connected to the conveying frame 1 in the X direction. The cutting assembly 2 is used to cut the cathode wire 7 and form a plurality of slits 73 on the cathode wire 7 (as Figure 6 shown), wherein the slits 73 extend in the X direction and are arranged at a preset angle with the X direction. One side of the slit 73 close to the discharge end 12 penetrates through the edge position of the cathode wire 7 to form a cutting opening communicating with the outside at the edge of the cathode wire 7; the formation of the slit 73 divides the cathode wire 7 into a main body portion 71 and a bent portion 72, as Figure 6 shown. Due to the existence of the slit 73, the bent portion 72 is only connected to the main body portion 71 through the connecting portion 74 ( Figure 6 The dotted line in indicates the connection between the bent portion 72 and the main body portion 71, that is, the connecting portion 74); in this embodiment, when cutting the cathode wire 7, the cathode wire 7 moves at a set speed under the action of the driving assembly 132. The cutting assembly 2 cuts the cathode wire 7 moving at a 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, when the cutting assembly 2 is cutting, its moving speed must be greater than the moving speed of the cathode wire 7 in order to cut the above-mentioned slit 73 on the cathode wire 7; after the cutting assembly 2 cuts a slit 73 of a predetermined length, the cutting assembly 2 quickly returns in the reverse direction in the X direction to re-cut the cathode wire 7 located behind the slit 73, so as to realize the formation of a plurality of spaced slits 73 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; vice versa); the discharge tips on the cathode wire 7 can significantly reduce the corona inception voltage, make the electric field more likely to generate corona discharge, and the electric field intensity is highly concentrated at the tip, so it is easier to ionize the air, generate a large number of free electrons and ions, and can achieve a better dust removal effect; in this embodiment, according to the actual use requirements of the user, the distance between two adjacent slits 73 can be set; the size of the distance S between two adjacent slits 73 is determined by the rate at which the driving assembly 132 drives the cathode wire 7 to move on the conveying frame 1 and the rate at which the cutting assembly 2 moves back and forth relative to the conveying frame 1.

[0070] As Figure 3As shown in the figure, this embodiment provides a bending component 3, which is arranged on the conveying rack 1 between the cutting component 2 and the discharging end 12. The bending component 3 is used to bend the bent part 72 formed by cutting so that the bent part 72 and the main body part 71 are bent at a preset angle. Since one side of the slit 73 facing the discharging end 12 penetrates the edge position of the cathode wire 7, when the bent part 72 moves to the position of the bending component 3, the bending component 3 applies an upward or downward acting force to the bent part 72, so that the bent part 72 can be bent relative to the main body part 71 when subjected to the acting force. The bent part is at the connection part (that is, the connecting part 74) between the bent part 72 and the main body part 71, so that the bent part 72 is bent relative to the main body part 71 at a preset angle. At this time, the bent part 72 at a preset angle with the main body part 71 constitutes the discharge tip of the cathode wire 7 (as Figure 15 shown). Exemplarily, in this embodiment, the angle between the bent part 72 and the main body part 71 can be 30°, 40°, 50° or 60°, or any angle value between 30° and 60°. In this embodiment, the preset angle between the bent part 72 and the main body part 71 is not limited. During actual production, the above-mentioned bending angle can be set accordingly according to the user's usage requirements.

[0071] Exemplarily, in order to further improve the electrostatic precipitation 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 arranged staggeredly (as Figure 4 shown), and the slits 73 on the opposite side penetrate the edge position of the cathode wire 7 on the side facing the discharging end 12. The reason for arranging the slits 73 on both sides staggeredly in the X direction is that on the one hand, it makes the distribution of the discharge tips on the cathode wire 7 more uniform to improve the electrostatic precipitation effect on the flowing gas; on the other hand, when the bent part 72 is bent at a preset angle relative to the main body part 71, a notch will be formed at the original position of the bent part 72. If the slits 73 on both sides are not arranged staggeredly in the X direction, when the bent part 72 is bent at a preset angle relative to the main body part 71, two notches will be formed at the same part of the cathode wire 7 along the Y direction, which is likely to reduce the structural strength of the cathode wire 7 and is not conducive to its use stability.

[0072] In this embodiment, a matching cutting assembly 2 and bending assembly 3 need to be provided on the other side of the conveying rack 1 along the Y direction. The working processes of the cutting assembly 2 and the bending assembly 3 are the same as above, that is, the cutting assembly 2 and the bending assembly 3 on both sides of the conveying rack 1 along the Y direction cooperate with each other and work simultaneously, and are used to cut the above-mentioned slits 73 on both sides of the cathode wire 7 along the Y direction respectively, and form bending parts 72 on both sides of the cathode wire 7 along the Y direction. When the above-mentioned bending part 72 is bent at a preset angle with the main body part 71 under the action of the bending assembly 3, the distribution density of the discharge tips on the cathode wire 7 is greater (as Figure 15 shown), which can further improve the electrostatic precipitation effect of the cathode wire 7; Exemplarily, several bending parts 72 distributed on both sides of the cathode wire 7 along the Y direction can be arranged in opposite bending directions, as Figure 13 , Figure 14 shown: several bending parts 72 on the same side can be bent downward, and several bending parts 72 on the other side can be bent upward, thereby obtaining the cathode wire 7 structure shown in Figure 15 . At this time, discharge tips formed by the bending parts 72 are distributed on both sides of the cathode wire 7 to improve the uniformity of corona discharge of the cathode wire 7. For example: when the discharge tips (such as barbs) on the cathode wire 7 are evenly arranged, corona discharge will occur simultaneously at multiple tips instead of concentrating in a certain area. This evenly distributed discharge can ensure that ionized gas (such as ions and free electrons) is uniformly generated on the entire electrode surface; uniform corona discharge can more effectively cover the entire cross-section of the flowing gas, enabling particles or molecules in the gas to interact more uniformly with the ionized gas; evenly distributed corona discharge can ensure that dust particles are effectively charged throughout the gas flow channel, thereby improving the dust removal efficiency.

[0073] Exemplarily, when bending parts 72 are provided on both sides of the cathode wire 7 along the Y direction and bent to a preset angle relative to the main body part 71 to form discharge tips, at this time, the driving assembly 132 needs to be centered relative to the cathode wire 7, as Figure 4 shown, so that the bending part 72 at a preset angle with the main body part 71 will not touch the driving assembly 132 during the movement of the cathode wire 7; The upper frame body 1321 is connected to a fixed rod on one side along the Y direction (so that the setting of the fixed rod will not affect the movement of the bending part 72 bent upward along with the cathode wire 7), and is fixedly installed on the conveying rack 1 through the fixed rod. The lower frame body 1321 is connected to a fixed rod on the other side along the Y direction (so that the setting of the fixed rod will not affect the movement of the bending part 72 bent downward along with the cathode wire 7), and is fixedly installed on the conveying rack 1 through the fixed rod.

[0074] Referring to Figure 2 , Figure 5 , Figure 6As shown in the figure, in an embodiment of the present application, the cutting assembly 2 includes a guide rail 21 disposed on the conveying frame 1. The guide rail 21 includes a slide rod 212 fixedly installed on the conveying frame 1 and a screw rod 211 rotatably installed on the conveying frame 1. Both the screw rod 211 and the slide rod 212 extend along the X direction and are spaced apart in the Y direction. The screw rod 211 is driven by a cutting motor 26 fixed to the conveying frame 1; a moving member 22 is movably connected to the guide rail 21 along the X direction. Two slide holes are provided through the moving member 22 along the X direction. One slide hole is slidably assembled with the slide rod 212, and an internal thread is provided in the other slide hole and is threadedly assembled with the screw rod 211. When the cutting motor 26 is started to drive the screw rod 211 to rotate, the moving member 22 is driven to move relative to the conveying frame 1 in the X direction; a cutting portion 23 is movably connected to the moving member 22 along the Y direction. When the cutting motor 26 drives the moving member 22 to move in the X direction, the cutting portion 23 moves synchronously in the Y direction, so as to cut the above-mentioned slit 73 on the cathode wire 7 and divide the cathode wire 7 into a main body portion 71 and a bent portion 72.

[0075] In this embodiment, when the cutting motor 26 drives the moving member 22 to move from the feeding end 11 to the discharging end 12 along the X direction through the screw rod 211, it is necessary to ensure that the moving speed of the moving member 22 is greater than the moving speed of the cathode wire 7 in order to cut the above-mentioned slit 73 on the cathode wire 7; when the moving speed of the moving member 22 along the X direction is fixed, the greater the moving speed of the cutting portion 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 users during the actual production process.

[0076] In the present 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 cathode line 7 at the next position above and below and form a preset slit 73; in the present embodiment, during actual production, the length of the slit 73 is determined, the moving speed of the cathode line 7 driven by the conveying component 13 is determined, and 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 moving part 22 to move in the X direction. 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, just completing the cutting of the slit 73, and controls the moving part 22 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 command 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 correspondingly controls the working time node for starting the cutting motor 26 again, so as 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 on the guide rail 21, the guide rod 24 extends along the X direction and is arranged at a preset angle with the X direction. In this embodiment, the speed of the cutting portion 23 moving along the Y direction depends on 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 the cutting portion 23 moving relative to the moving member 22 along the Y direction when the moving member 22 moves along the X direction; otherwise, the smaller the speed. Figure 2 As shown, a slide groove extending along the Y direction is provided on the movable member 22, 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 the first elastic member 25 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 a 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 part 23 is synchronously driven to move along the X direction at a preset speed. During the movement along the X direction, the first elastic member 25 synchronously drives the cutting part 23 to move relative to the moving member 22 along the Y direction, so that the cutting part 23 always abuts against the side wall of the guide rod 24; as Figure 6 shown, when the moving member 22 moves to a preset position along the X direction, the cutting part 23 also synchronously moves to a preset position along the Y direction relative to the moving member 22 under the action of the first elastic member 25 (at this time, the stretching amount of the first elastic member 25 is the smallest). At this time, the cut 73 cut by the cutting part 23 on the cathode wire 7 completely penetrates the edge position on one side of the cathode wire 7 along the Y direction. At this time, the central controller controls the cutting part 23 to stop cutting work and controls the cutting motor 26 to rotate in the reverse direction to drive the moving member 22 and the cutting part 23 to quickly return to the initial position. When the moving member 22 returns in the reverse direction, the cutting part 23 is synchronously moved relative to the moving member 22 under the action of the first elastic member 25 (so that the stretching amount of the first elastic member 25 gradually increases) until it moves to the initial position (the cutting motor 26 stops working) and waits for the start command of the central controller to cut the next part of the cathode wire 7.

[0079] Referring to Figure 2 shown, in an embodiment of the present application, the cutting part 23 includes a cutting head 231 and a mounting bracket 232. The mounting bracket 232 is movably connected to the moving member 22 along the Y direction. The cutting head 231 is arranged on the mounting bracket 232. The cutting head 231 is used to cut the cathode wire 7 and form the above-mentioned cut 73; the first elastic member 25 is connected between the mounting bracket 232 and the moving member 22; exemplarily, the cutting head 231 in this solution can be a laser emitter (using a laser beam with a high energy density to irradiate the material surface, so that the material quickly absorbs the laser energy and is converted into heat energy, thereby realizing the melting, vaporization or combustion of the material and finally forming a cut) or an arc emitter (a processing method that uses a high-temperature arc to heat the metal, melts it and blows it away to form a cut); when a laser emitter is selected for cutting, by controlling the power of the laser emitter, the energy of the emitted laser beam is further controlled, so as to realize the cutting of the cathode wire 7; when an arc emitter is selected for cutting, by controlling the working power of the arc emitter, the temperature generated by the arc is further controlled and used to cut the cathode wire 7; since the above two cutting methods are both conventional cutting methods in the prior art, their working principles will not be described in detail.

[0080] In this embodiment, since the side of the mounting bracket 232 facing away from the cathode wire 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 moving member 22 to move more smoothly along the X direction along the side wall surface of the guide rod 24 when moving along the X direction, this embodiment provides a structure that enables the mounting bracket 232 to move more smoothly when abutting against the side wall surface of the guide rod 24 under the action of the first elastic member 25; Exemplarily, a groove can be formed on the side of the mounting bracket 232 facing the guide rod 24, and a rotating column 2322 is rotatably installed in the groove. The circumferential side wall of the rotating column 2322 is in abutting contact with the side wall of the guide rod 24. When the moving bracket moves along the X direction, the mounting bracket 232 is synchronously driven to move along the X direction and closely abuts against the side wall of the guide rod 24, so that the contact between the mounting bracket 232 and the side wall of the guide rod 24 is changed from the original sliding contact to rolling contact, thereby improving the sensitivity of the mounting bracket 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 through a bearing, and the setting of the bearing can make the rotation of the rotating column 2322 smoother.

[0081] Referring to Figure 2 , Figure 5 , Figure 6 As shown, in an embodiment of the present application, the mounting bracket 232 has a telescopic rod 2321 that can be telescoped along the Y direction. The telescopic rod 2321 can be an electric adjustment rod, and the cutting head 231 is fixedly connected to the telescopic end of the telescopic rod 2321; As Figure 5 shown, the guide rod 24 includes a first rod 241 and a second rod 242 connected to each other. The first rod 241 extends along the X direction, and the second rod 242 is arranged at a preset angle with the X direction. In order to ensure a smooth transition at the connection between the first rod 241 and the second rod 242, the guide rod 24 in this solution is preferably integrally provided.

[0082] In this embodiment, the cutting head 231 has a first working mode and a second working mode. As Figure 6 shown, when the cutting head 231 moves closely along the side wall of the second rod 242, the cutting head 231 is in the second working mode at this time, and is used to cut the cathode wire 7 to form the cut 73 that penetrates one side of the edge of the cathode wire 7; As Figure 5 shown, when the cutting head 231 moves closely along the side wall of the first rod 241, the cutting head 231 is in the first working mode at this time. At this time, the cutting head 231 is used for the connection between the bent portion 72 and the main body portion 71 ( Figure 6At the position of the dashed line shown in [description], that is, the connecting part 74) is preheated; in order to facilitate the control of the working mode of the cutting head 231 and enable it to switch 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 through 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 is only used for preheating the connection part (connection part 74) between the bending part 72 and the main body part 71, and does not cut it. The role of preheating is as follows: it is convenient for the subsequent bending assembly 3 to perform bending processing on the bending part 72. Because when the connection part 74 is heated to a certain temperature, the physical properties of the connection part 74 will change. For example, the yield strength of the connection part 74 decreases, making it easier to reach the stress level required for large plastic deformation. At the same time, preheating can increase the plasticity of the 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 requirement applied to the bending assembly 3; further preheating can cause the bending part 72 to have a springback phenomenon after bending, making the bent angle more stable.

[0084] In this embodiment, when the cutting head 231 is in the first working mode, the moving speed V1 of the cutting head 231 driven by the cutting motor 26 along the X direction through the screw 211 should be consistent with the moving speed V of the cathode wire 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), so as to realize the connection between the bending part 72 and the main body part 71, such as Figure 6 Preheating is performed at the position shown by the dashed line in [description]; 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 through the central controller.

[0085] In this embodiment, when the moving frame drives the cutting head 231 to move to the connection part of the first rod 241 and the second rod 242 (as shown in the local enlarged view in [description]), at this time, the central controller adjusts the operating speed of the cutting motor 26, and drives the moving part 22 to move along the X direction at a faster speed through the screw 211, so that a difference is generated between the speed of the moving part 22 and the cathode wire 7 along the X direction, that is, V1 is greater than V; thus, when the moving part 22 drives the cutting head 231 and makes the cutting head 231 move closely along the side wall of the second rod 242, the cutting head 231 can move synchronously in the Y direction under the action of the first elastic member 25, so that when the cutting head 231 moves along the second rod 242 to a preset position (such as Figure 5 Shown in [description]), Figure 6), at which time the cutting head 231 cuts a slit 73 on the cathode line 7 that penetrates 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 moving 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 corresponding position directly below the cutting head 231 just corresponds 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 an instruction again, so as to cut the upper and lower parts of the cathode line 7 and form the above-mentioned slit 73.

[0086] Exemplarily, in this embodiment, when the central controller controls the cutting motor 26 to start working again and drives the moving 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 of the cutting head 231, it takes a certain amount of time for it to reach the preset power and the temperature when it can cut the stainless steel sheet, 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 achieve cutting of the stainless steel plate). 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 moving 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 portion 72 and the main body 71 (that is, the connecting portion 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 portion 72 and the main body 71 (causing unnecessary cutting and affecting the connection strength between the bending portion 72 and the main body 71).

[0087] In this embodiment, the preheating between the bending portion 72 and the main body portion 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 for preheating the connecting portion 74. However, when the cutting head 231 needs to cut the cathode wire 7, the central controller also needs to control the cutting head 231 to increase the operating power and reach the preset cutting power before it can cut the cathode wire 7. During this period, a certain waiting time is required (although this time is short, but each cutting process has to wait for this short time, and the accumulation of a large number of such short times results in a significant increase in the ultimately wasted time, which is not conducive to improving the cutting efficiency). Second, when the cutting head 231 moves along the first rod 241, the central controller controls the cutting head 231 to start and directly approach 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 the stainless steel thin plate) is just used to preheat the connection between the bending portion 72 and the main body portion 71, that is, the time required for the cutting head 231 to reach the preset stable cutting power is saved, and at the same time, the heat generated by the cutting head 231 before reaching the preset cutting power is used to preheat the connection between the bending portion 72 and the main body portion 71, improving the cutting efficiency and reducing the waste of energy. Preferably, in this embodiment, the second method is selected to preheat the connection (that is, the connecting portion 74) between the bending portion 72 and the main body portion 71.

[0088] Referring to Figure 3 , Figure 7 As shown in, in an 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. The bending rod 31 has a standby position and a bending position; and a connecting rod 32 extending along the Y direction, and one end of the connecting rod 32 away from the cathode wire 7 is fixedly connected to the free rotating end of the bending rod 31; a pressing member 33 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 wire 7, that is, when the bending rod 31 is in the standby position, the pressing member 33 is below the cathode wire 7 (not in contact with the lower surface of the cathode wire 7) or the pressing member 33 is above the cathode wire 7 (not in contact with the upper surface of the cathode wire 7). In this embodiment, the bending directions of several bending portions 72 on both sides of the cathode wire 7 along the Y direction are arranged in opposite directions. Therefore, when the pressing member 33 on one side of the cathode wire 7 is in the standby position, it is below the cathode wire 7 and not in contact with the lower surface of the cathode wire 7; when the pressing member 33 on the opposite side is in the standby position, it is above the cathode wire 7 and not in contact with the upper surface of the cathode wire 7.

[0089] Under the conveyance of the conveyance component 13, the cathode wire 7 is such that when the bent portion 72 moves to a position corresponding to the pressing member 33, as Figure 3 shown, the bent rod 31 on one side of the cathode wire 7 along the Y direction rotates upward, and drives the pressing member 33 to contact the lower surface of the bent portion 72 and push the bent portion 72 to bend upward relative to the main body portion 71; at the same time, the bent rod 31 on the opposite side rotates downward, and drives the pressing member 33 to contact the upper surface of the bent portion 72 and push the bent portion 72 to bend downward relative to the main body portion 71 (as Figure 7 shown); as Figure 10 shown, in this embodiment, the bending process of the bent portion 72 on one side of the cathode wire 7 along the Y direction is taken as an example for description: when the bent portion 72 moves with the cathode wire 7 to a suitable position above the pressing member 33, control the bent rod 31 to rotate upward, and then drive the pressing member 33 to abut upward against the lower surface of the bent portion 72 through the connecting rod 32. As the bent rod 31 continues to rotate upward, the bent portion 72 is forced to bend relative to the main body portion 71 through the pressing member 33. At this time, a bend is generated at the connection portion (that is, the connecting portion 74) between the bent portion 72 and the main body portion 71; until when the bent rod 31 rotates to a preset bending position (at this time, the bent portion 72 bends relative to the main body portion 71 to a preset angle), control the bent rod 31 to rotate rapidly in the reverse direction, so that the bent rod 31 drives the pressing member 33 to quickly return to the initial standby position, so as not to hinder the movement of the cathode wire 7 toward the discharge end 12 along with the conveyance component 13; after the bent rod 31 drives the pressing member 33 to move to the standby position, continue to wait for the subsequent bent portion 72, and when the subsequent bent portion 72 moves to a suitable position above the pressing member 33 again, control the bent rod 31 to rotate upward again, so as to realize the bending process of the bent portion 72; during the above bending process of the bent portion 72, the cathode wire 7 does not need to stop, so that the bending process is completed during the movement of the cathode wire 7 on the conveying rack 1, improving the bending efficiency.

[0090] In this embodiment, as Figure 10 shown, since during the process of the bent rod 31 driving the pressing member 33 to rotate upward, the cathode wire 7 always moves toward the discharge end 12 along the X direction at a predetermined speed; as Figure 16As shown, assuming that the bent rod 31 remains at the angle α shown in the figure unchanged, under the conveying action of the conveying assembly 13, the cathode wire 7 moves along the X direction from the feeding end 11 to the discharging end 12, which will also cause the bending angle of the bent portion 72 relative to the main body portion 71 to further increase (that is, the effect of bending the bent portion 72 relative to the main body portion 71 is achieved). Therefore, when the bent rod 31 remains stationary, the end of the cathode wire 7 towards the discharging end 12 will also force the bent portion 72 to bend relative to the main body portion 71; in this embodiment, the bending of the bent portion 72 relative to the main body portion 71 is achieved by two processes together: one is that the cathode wire 7 moves along the X direction towards the discharging end 12, and the other is that the bent rod 31 drives the pressing member 33 to rotate upward and forces the bent portion 72 to bend relative to the main body portion 71; therefore, when the bent portion 72 is bent relative to the main body portion 71 to a preset included angle, since the cathode wire 7 in this solution always moves towards the discharging end 12 at a certain speed, the bent rod 31 only needs to rotate a small angle (compared with the case where the cathode wire 7 is stationary) to achieve bending the bent portion 72 relative to the main body portion 71 to the preset included angle, thereby improving the bending efficiency.

[0091] Referring to Figure 11 、 Figure 12 As shown, in an embodiment of the present application, in order to enable the pressing member 33 and the bent portion 72 to have a larger contact area, the pressing member 33 is set to a flat plate shape in this embodiment. As Figure 11 shown, there is a large contact area between the pressing member 33 and the bent portion 72, which can make the interaction force generated between the bent portion 72 and the pressing member 33 more evenly distributed on the bent portion 72 when the bent rod 31 drives the pressing member 33 to force the bent portion 72 to bend relative to the main body portion 71, so as to prevent the acting force between the two from being overly concentrated in a small area, resulting in yield deformation at the contact position between the bent portion 72 and the pressing member 33 during the process of driving the bent portion 72 to bend relative to the main body portion 71 (causing unnecessary bending deformation of the bent portion 72 itself), affecting the final bending angle of the bent portion 72 relative to the main body portion 71. At the same time, the bending deformation of a part of the bent portion 72 will cause a change in the shape of the discharge tip, thereby changing the distribution of the local electric field, making the corona discharge uneven and reducing the efficiency of the electrostatic precipitation.

[0092] In this embodiment, during the process of the bent rod 31 driving the pressing member 33 to rotate upward, the cathode wire 7 moves synchronously towards the discharging end 12, so that the contact position between the pressing member 33 and the lower surface of the bent portion 72 also changes, so that the acting force of the pressing member 33 on the bent portion 72 can be applied to different regional positions successively, further reducing the probability of yield bending deformation of a certain part of the bent portion 72 due to stress concentration in a certain part of the bent portion 72.

[0093] In this embodiment, the contact position of the pressing member 33 relative to the bent portion 72 changes. Therefore, in order to ensure that the flat pressing member 33 can always be in contact with the surface of the bent portion 72 during the entire bending process, the pressing member 33 is rotatably installed between the connecting rod 32, and the rotation axis of the pressing member 33 extends along the Y direction; as Figure 12 shown, the pressing member 33 is provided with a hole for inserting a part of the connecting rod 32, and one end of the connecting rod 32 is rotatably installed in the hole. The end of the connecting rod 32 inserted into the hole is provided with a stepped shape, and a torsion spring 34 is sleeved on the thinner-diameter connecting rod 32. One end of the torsion spring 34 is fixed on the pressing member 33, and the other end is fixed on the connecting rod 32; therefore, when the bending rod 31 drives the pressing member 33 to press against the surface of the bent portion 72, as the bending rod 31 rotates and the cathode wire 7 moves, the pressing member 33 can rotate relative to the connecting rod 32, so that the pressing member 33 always remains in contact with the bent portion 72, and at this time, the torsion spring 34 stores energy continuously; when the bending rod 31 rotates to a preset bending position and controls the bending rod 31 to rotate rapidly in the reverse direction and perform a rapid return, the pressing member 33 quickly returns synchronously under the action of the torsion spring 34, so that when the bending rod 31 rotates to the standby position, the relative position angle of the pressing member 33 relative to the connecting rod 32 also returns to the initial state synchronously; in this embodiment, when the bending rod 31 is in the standby position, the relative position angle relationship between the pressing member 33 and the connecting rod 32 under the action of the torsion spring 34 satisfies: when the bent portion 72 moves to a suitable position above the pressing member 33 as the cathode wire 7 moves, control the bending rod 31 to rotate upward, so that when the pressing member 33 contacts the lower surface of the bent portion 72, the pressing member 33 can just be in complete contact with the lower surface of the bent portion 72, so as to achieve the maximum contact area between the pressing member 33 and the bent portion 72 and avoid stress concentration as much as possible.

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

[0095] In this embodiment, the pushing component 5 is movably connected to the conveying frame 1 along the Z direction. The pushing component 5 includes a driving rod 52 and a driven rod 51. Both the driving rod 52 and the driven rod 51 extend along the Z direction and are spaced apart in the Y direction. The upper ends of the driving rod 52 and the driven rod 51 are fixedly connected. The driven rod 51 is slidably assembled in the sliding cavity 14 along the Z direction, and a second elastic member 53 is provided between the driven rod 51 and the pressing frame 42 (such as Figure 11as shown); Exemplarily, the second elastic member 53 may be a spring or other elastic components; The pushing assembly 5 composed of the active rod 52 and the passive rod 51 has a natural position away from the pressing assembly 4 and a squeezing position close to the pressing assembly 4. When the pushing assembly 5 is in the natural position, the compression amount of the second elastic member 53 connected between the passive rod 51 and the pressing frame 42 is relatively small. When the pushing assembly 5 is in the squeezing position, the compression amount of the second elastic member 53 connected between the passive rod 51 and the pressing frame 42 is relatively large; When the bending portion 72 moves with the cathode wire 7 to a suitable position above the pressing member 33, the bending rod 31 rotates from the standby position to the bending position. At the same time, the pushing assembly 5 is controlled to move synchronously from the natural position to the squeezing position, that is, the pushing assembly 5 (the active rod 52, the passive rod 51) is driven to move downward and squeeze the second elastic member 53, so that the pushing force applied by the pushing assembly 5 is applied to the pressing frame 42 through the second elastic member 53, thereby increasing the pressing force between the pressing portion 41 and the cathode wire 7; In this embodiment, the above-mentioned pressing assembly 4 and pushing assembly 5 are provided mainly to prevent the bending force applied by the pressing member 33 on the bending portion 72 from causing the part of the cathode wire 7 around the connecting portion 74 to bend upward synchronously when the bending rod 31 drives the bending portion 72 to bend relative to the main body portion 71 through the pressing member 33 (causing unnecessary bending deformation of the whole cathode wire 7, affecting the distribution of the electric field and thus affecting the electrostatic precipitation effect); In this embodiment, when the bending rod 31 drives the bending portion 72 to bend through the pressing member 33, the pushing assembly 5 synchronously applies a pushing force on the pressing frame 42 and transmits the pushing force to the pressing portion 41, so as to press against the area near the connecting portion 74 through the pressing portion 41, avoiding the area from being bent synchronously with the connecting portion 74 under the bending force applied by the bending rod 31; As Figure 8 shown, when the bending rod 31 drives the bending portion 72 to bend from bottom to top, the pressing portion 41 should be arranged at the upper surface position of the cathode wire 7 to prevent the area close to the connecting portion 74 from bending synchronously; The bending rod 31 on the other side of the cathode wire 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 arranged at the lower surface position of the cathode wire 7 (as Figure 7 shown), because when the bending rod 31 at this position drives the bending portion 72 to bend from top to bottom, the area of the main body portion 71 around the connecting portion 74 receives the downward bending force transmitted from the connecting portion 74. Therefore, arranging the pressing portion 41 at the lower surface of the cathode wire 7 and abutting against the surface of the cathode wire 7 can better avoid unnecessary bending deformation of the area 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 part 72 is bent relative to the main body part 71 to a preset included angle, at this time, the bending rod 31 no longer applies a bending force to the bending part 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 moves synchronously from the extrusion position to the natural position to remove the acting force applied to the pressing frame 42, so that the pressing force between the pressing part 41 and the surface of the cathode wire 7 decreases and returns to the initial level. The reason for such a setting is that when the pressing force between the pressing part 41 and the cathode wire 7 is relatively large, to a certain extent, it increases the resistance when the cathode wire 7 moves, so that the conveying assembly 13 needs to provide a greater conveying force to drive the cathode wire 7 to move on the conveying frame 1. When the bending part 72 is bent relative to the main body part 71 to the preset included angle, at this time, since the main body part 71 around the connecting part 74 no longer receives any bending force, the pressing force between the pressing part 41 and the cathode wire 7 can be reduced to reduce the moving resistance of the cathode wire 7 on the conveying frame 1, thereby reducing the operating power required for the conveying assembly 13 to convey the cathode wire 7 to move, which helps to reduce the energy consumption.

[0097] In this embodiment, when the connection between the bending part 72 and the main body part 71 (that is, the connecting part 74) completely passes over the pressing part 41, the bending rod 31 can be controlled to act and the bending part 72 can be bent, so as to avoid the bending rod 31 starting to perform the bending action when the connecting part 74 has not passed over the pressing part 41, resulting in the bending part 72 being unable to bend relative to the main body part 71 at the connecting part 74. In order to more accurately achieve the above process, a monitoring unit can be set on the conveying frame 1 at the position of the pressing part 41 to collect the moving position state of the bending part 72 in real time. When the connecting part 74 completely passes over the pressing part 41, the bending rod 31 is controlled to act immediately and the bending part 72 is bent. Exemplarily, the collecting unit can be electrically connected to the central controller, and the central controller receives the moving position information of the bending part 72 collected by the collecting unit in real time and controls whether the bending rod 31 performs the bending action according to the moving position information of the bending part 72. In this embodiment, the bending process of the bending part 72 should be completed as soon as possible to avoid the connecting part 74 moving too far after passing over the pressing part 41, resulting in the pressing part 41 being unable to prevent unnecessary bending deformation of the main body part 71 around the connecting part 74.

[0098] Refer to Figure 7 、 Figure 8 、 Figure 11As shown, in an embodiment of the present application, the cathode wire production device of the electrostatic precipitator further includes a driving disk 6 rotatably installed on the outer side wall of the conveying frame 1. 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 arrange the connecting rod 32 and the pressing member 33 and enable them to rotate synchronously with the rotation of the bending rod 31, disconnection points may be provided at both positions of the conveying frame 1 along the Y direction (in this solution, the conveying frame 1 is fixedly installed on the ground or other platforms in the workshop), for accommodating the connecting rod 32, and synchronously driving the pressing member 33 to rotate through the rotation of the bending rod 31 for bending the bending part 72; the bending rod 31 extends radially along the driving disk 6 and the end of the bending rod 31 away from the connecting rod 32 is fixedly installed on the circumferential side wall of the driving disk 6; as Figure 11 As shown, a top push rod 54 extending radially along the driving disk 6 is further fixedly connected to the circumferential side wall of the driving disk 6. The top push rod 54 and the bending rod 31 are spaced and connected to the circumferential side wall of the driving disk 6. An axle pin 55 extending along the Y direction is connected to the side of the top push rod 54 facing the top push assembly 5. A slideway 521 matching the axle pin 55 is provided at the bottom of the active rod 52, so that the axle pin 55 is movably assembled in the slideway 521.

[0099] In this embodiment, it is set that 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 disk 6, the top push rod 54 and the axle pin 55, as Figure 11As shown, when the driving disk 6 rotates counterclockwise, the pressing member 33 is driven by the bending rod 31 to bend the bending portion 72. At the same time, through the cooperation of the ejector rod 54, the pin 55, and the slideway 521, the active rod 52 is forced to move downward in the Z direction, and the passive rod 51 of the synchronous belt moves downward in the sliding cavity 14, compressing the second elastic member 53. Thus, a certain amount of force is applied downward to the pressing frame 42 through the second elastic member 53, and this force finally acts on the cathode wire 7 through the pressing portion 41 that abuts against the surface of the cathode wire 7 (that is, on the main body portion 71 around the connecting portion 74). This force has the effect of preventing the main body portion 71 around the connecting portion 74 from bending upward, so as to avoid unnecessary bending deformation of the main body portion 71 area around the connecting portion 74 due to a large bending force when the bending rod 31 forces the bending portion 72 to bend relative to the main body portion 71 through the pressing member 33; when the bending portion 72 is bent relative to the main body portion 71 to a preset angle, the driving disk 6 is controlled to rotate rapidly in the reverse direction so that the bending rod 31 can quickly return to the standby position. During this process, through the cooperation of the axial direction and the slideway 521, the active rod 52 and the passive rod 51 of the belt move upward in the Z direction, thereby removing the force applied to the pressing frame 42 (so that the ejector assembly 5 returns from the extrusion position to the natural position), and further reducing the abutting force between the pressing portion 41 and the surface of the cathode wire 7, for reducing the operating power required for the conveying assembly 13 to convey the cathode wire 7 to move.

[0100] In this embodiment, the rotation angle, rotation direction, and rotation speed of the driving motor 61 are controlled by the central controller, so as to realize the coordinated cooperation of the above-mentioned components (the ejector assembly 5, the pressing assembly 4, and the 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, to ensure the high-quality realization of the bending process of the bending portion 72 and form a discharge tip, improving the electrostatic precipitation effect after the cathode wire 7 is put into use.

[0101] In this embodiment, since the connecting portion 74 is the connecting portion 74 between the discharge tip (the bending portion 72 at a preset angle with the main body portion 71) and the main body portion 71, when the cutting head 231 preheats the connecting portion 74, due to the high temperature at the connecting portion 74, it is easy to cause an oxide layer to form on the surface of the connecting portion 74. This is because the stainless steel thin plate undergoes a chemical reaction with oxygen in the air at high temperature, and the above-mentioned oxide layer covering the surface of the connecting 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 connecting portion 74 between the discharge tip and the main body portion 71, it will significantly increase the contact resistance; at the same time, the oxide layer will hinder the conduction and accumulation of charges, reducing the generation amount of ionized gas (ions and free electrons), thereby affecting the electrostatic precipitation effect.

[0102] AsFigure 11 As shown, in this embodiment, in order to remove the oxide layer adhering 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). A scraping brush 44 is provided on the circumferential side 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 wire 7, and the scraping brushes 44 are both in contact with the surface of the cathode wire 7; the two scraping shafts 43 are connected to the pressing shaft 421 through a pulley group 45. When the pressing portion 41 is in contact with the surface of the cathode wire 7, the cathode wire 7 moves toward the discharge end 12 under the action of the conveying assembly 13, and the pressing portion 41 of the synchronous belt rotates relative to the pressing frame 42, thereby causing the pressing shaft 421 to drive the two scraping shafts 43 to rotate through the pulley group 45. When the connecting portion 74 moves to the position of the two scraping shafts 43 along with the cathode wire 7, the oxide layer adhering to the upper and lower surfaces of the connecting portion 74 is scraped and cleaned by the scraping brush 44 provided on the circumferential side of the scraping shaft 43, so that the oxide layer adhering to the surface of the connecting portion 74 is separated from the main body portion 71 (after the cathode wire 7 is completely sent out from the discharge end 12, the cathode wire 7 is tapped with a certain force, and the oxide layer peeled off from the surface of the connecting portion 74 can be shaken off from the cathode wire 7), so as to improve the electrostatic precipitation effect of the cathode wire 7 during use.

[0103] Second, the embodiment of the present application provides a production method, which uses the electro-dust precipitator cathode wire production device in the above embodiment, and includes the following steps:

[0104] S1: First, drive the moving member 22 to drive the cutting head 231 to move along the X direction at the same speed as the cathode wire 7. At the same time, control the telescopic rod 2321 to extend at a certain rate. At this time, the cutting head 231 is used to preheat the connection between the bent portion 72 and the main body portion 71, so as to facilitate better bending of the bent portion 72 by the bending assembly 3 subsequently.

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

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

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

[0108] S5: Repeat the above S1 - S4 to process multiple bent portions 72 on the main body portion 71 that form a preset included angle with the main body portion 71, and form the discharge tip of the cathode wire 7.

[0109] In summary, the cathode wire production device in this solution cuts the cathode wire 7 through the cutting assembly 2 to form the main body portion 71 and the bent portion 72, and bends the bent portion 72 through the bending assembly 3 so that the bent portion 72 forms a preset included angle with the main body portion 71, making the bent portion 72 that forms a preset included angle with the main body portion 71 constitute the discharge tip; there is no waste generated during the production process of the cathode wire 7 in this solution, eliminating the need to set up additional collection equipment and ensuring the cleanliness of the operation site; the cathode wire production device in this solution can quickly form a discharge tip (the bent portion 72 that forms a preset included angle with the main body portion 71) on the cathode wire 7 through the cooperation of the cutting assembly 2 and the bending assembly 3. Compared with the traditional method of welding barbs or needle bodies on the surface of a metal tube, the production efficiency is significantly improved; moreover, the tip for discharging in this solution is directly formed by bending the bent portion 72 relative to the main body portion 71. Compared with the traditional method of connecting two separate components by welding, the connection between the bent portion 72 and the main body portion 71 in this solution is more reliable and firm, with high use stability.

[0110] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
