Description
Technical Field
[0001] This invention relates to the technical field of continuous hot-dip galvanizing high-speed unit production line, and particularly to a continuous hot-dip galvanizing visible air knife edge baffle slag removal device. Background Technology
[0002] In continuous hot-dip galvanizing production lines, as the process speed increases, the air knife pressure rises, or the air knife edge baffles become too close to the strip edge, slag adhesion easily occurs on the air knife edge baffles. The composition of the zinc bath used for different product types varies, resulting in different degrees of slag adhesion. Often, the lack of effective monitoring methods or untimely monitoring by operators during production leads to product degradation. Slag adhesion on the air knife edge baffles is generally handled manually using cleaning tools. However, the cleaning area is limited by the relative position of the air knife holder and surrounding mechanical structures, making slag removal difficult, resulting in unsatisfactory cleaning effects and long cleaning times, thus increasing the amount of product degradation.
[0003] During the cleaning process of the air knife edge baffle, the production line needs to slow down or open the air knife edge baffle to its maximum position for cleaning. During this cleaning time, a large number of defective or substandard products are generated, resulting in a decline in product quality. Furthermore, personnel work in a high-temperature, liquid metal environment during the cleaning process, posing significant safety risks and increasing their occupational hazard exposure time.

The upper and lower parts of the tail of the side baffle bracket connecting block 103 are respectively provided with an upper positioning block 1031 and a lower positioning block 1032, which facilitates connection and positioning with the original air knife drive device in the prior art. This allows the original air knife drive device to push the side baffle bracket 101 to move on the air knife side baffle 2 to adjust the distance between the air knife side baffle 2 and the strip steel 3.

[0082] like Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 10As shown, the bottom of the side baffle bracket 101 is provided with a rack and pinion groove 10107; the rack and pinion groove 10107 includes a rear rack and pinion groove 1010701 and a front rack and pinion groove 1010702 arranged parallel to each other, respectively corresponding to the rack and pinion assemblies 1044 of the two sets of scraper drive assemblies, so that the rack and pinion assemblies 1044 can slide smoothly at the bottom of the side baffle bracket 101; the rack and pinion assembly 1044 includes: a rack and pinion slider 10441, which is installed in the rack and pinion groove 10107; the rack and pinion...

[0083] like Figure 2 and Figure 3 As shown, the present invention also includes two vibrators 107 respectively disposed on both sides of the front end of the side baffle bracket 101, for transmitting vibration to the air knife side baffle 2 to vibrate and dislodge impurities on the air knife side baffle 2; the vibrator 107 includes a vibrating rod 10701 and a vibrating head 10702, the bottom of the vibrating rod 10701 is connected to the vibrating actuator of the vibrator 107, and the top is provided with the vibrating head 10702.
[0084] The present invention relates to a slag removal method for a continuous hot-dip galvanizing visible air knife edge baffle device. The device features remote monitoring of slag adhesion on the air knife edge and remote operation for handling slag. It includes a video feed for remotely monitoring the slag adhesion on the air knife edge baffle, and lighting and camera devices for acquiring the monitoring feed to determine the amount and condition of slag adhesion at the affected area. Visual monitoring allows for timely acquisition of slag information and immediate slag removal, preventing product degradation. Independent electric scraper cleaning devices are designed at both the front and rear of the air knife edge baffle, capable of independently driving single-sided or double-sided scrapers to clean the air knife edge baffle quickly and accurately within a limited space. The air knife edge baffle adopts a quick-disassembly or installation structure, which facilitates the maintenance of the air knife edge baffle. It has an automatic positioning and self-locking structure to ensure that the installed air knife edge baffle is in a more ideal installation state. In particular, the verticality of the air knife edge baffle is maintained, keeping it aligned with the running strip on the production rolling line. It has a relatively reasonable and accurate adjustment, which makes it easy for the air knife edge baffle and the strip to be on the same plane and to maintain a correct position with sufficient precision. The airflow turbulence is improved, preventing the strip edge from becoming too thick and obtaining a more uniform coating.
[0085] like Figure 1As shown, the air knife edge baffle is mainly used to eliminate turbulent airflow on the strip steel to facilitate air knife spraying. The strip steel 3 is scraped away by the gas ejected from the air knife blade, removing excess zinc liquid. This ensures precise control of the zinc coating on the strip steel 3. The airflow ejected from the air knife blade is horizontal, forming a horizontal scraping line 4 on the strip steel as shown in the figure. There is a gap between the strip steel 3 and the air knife edge baffle 2. This gap is directly or indirectly related to the product type, strip steel thickness, coating thickness, and unit production speed. The appropriate gap is adjusted according to different products, generally between 2-20 mm, to minimize airflow turbulence, prevent zinc dross splashing, and ensure the quality of the produced product. The surface coating of the product has good transverse uniformity, but problems such as poor strip edge shape or assembly of zinc pot roller system can cause strip edge vibration, resulting in airflow turbulence. This causes the molten zinc to splash onto the air knife lip and air knife edge baffle. When the slag on the air knife edge baffle reaches a certain amount, it will lead to a vicious cycle, further hindering the turbulence of stable airflow. Zinc slag splashes onto the strip, causing zinc slag defects. Because the air knife edge baffle cannot stabilize the flow, the coating thickness of the strip edge will be uneven, resulting in edge thickness defects. After being coiled under high tension, edge waviness defects will occur. When the customer opens the steel coil, the edge waviness of the strip will render it unusable or result in unqualified products.
[0086] refer to Figure 1 As shown in the schematic diagram of the visible air knife edge baffle cleaning device, the air knife edge baffle 2 installed on the visible air knife cleaning device 1 maintains an adjustable distance of 1-30mm from the strip steel 3. The visible air knife cleaning device 1 includes an edge baffle bracket 101. The distance between the visible air knife cleaning device 1 and the strip steel 3 is achieved by moving the edge baffle bracket connecting block 103 connected to the edge baffle bracket 101 through a conventional air knife edge baffle driving device. Slag will adhere to the edge of the air knife edge baffle 2 near the strip steel due to the horizontal scraping of the air knife lip around the horizontal line 4. To remove the slag adhering to the air knife edge baffle, the air knife edge baffle bracket 101 is equipped with...
[0087] refer to Figure 2 As shown in the perspective view of the visible air knife edge baffle cleaning device, the visible air knife edge baffle cleaning device 1 is an integrated structural design. The edge baffle bracket 101 is connected to the edge baffle bracket connecting block 103. The visible air knife edge baffle 2 is installed and positioned on the visible air knife cleaning device 1 through a T-slot. The edge baffle bracket connecting block 103 is connected to the original air knife drive device in the prior art (omitted in this invention). The edge baffle bracket connecting block 103 drives the edge baffle bracket 101 to move laterally to adjust the distance between the air knife edge baffle 2 and the strip steel 3. The lateral movement direction is parallel to the air knife and is symmetrically arranged on both sides of the coated strip steel 3. The edge baffle bracket 101 is a cuboid shape and is laterally connected to the edge baffle bracket connecting block 103.
[0088] The air knife side baffle 2 adopts a T-shaped design, which facilitates disassembly, assembly, and positioning, and maintains the accuracy of the installation thickness. Constrained by its own weight, the air knife side baffle 2 is vertically installed inside the air knife side baffle bracket 101. The air knife side baffle 2 is installed by a pull-out method. The T-shaped mounting positioning block of the air knife side baffle 2 is designed with two vertically downward circular holes. The bottom of the circular holes adopts a hemispherical structure, which is combined with the cylindrical positioning pin on the side baffle positioning pin 102. The top of the pin is hemispherical. The hemispherical positioning magnet 1024 matches the positioning hole of the air knife side baffle, so that the air knife side baffle can be accurately fixed and positioned inside the air knife side baffle bracket.
[0089] The T-shaped air knife side baffle 2 is installed inside the T-shaped mounting groove of the side baffle within the air knife side baffle bracket 101. During installation and removal, it is slid in from the side end face and positioned using the mounting holes on the air knife side baffle bracket 101, where the side baffle positioning pin 102 is inserted. (Reference) Figure 8 , 20 As shown in Figures 21 and 22, the side baffle positioning pin 102 has a first positioning pin 1022 and a second positioning pin 1023. The side of the side baffle positioning pin 102 has four side baffle positioning pin disassembly ports 1021 for easy installation and disassembly, achieving the purpose of quick disassembly and replacement of the air knife side baffle 2. The tilt direction of the reference camera 1051 of the camera 105 is the direction of slag adhesion on the air knife side baffle. The illumination direction of the lighting lamp 106 is the direction of slag adhesion on the air knife side baffle. The directions of the camera 105 and the lighting lamp 106 are adjustable to better accommodate changes in the length and width specifications of the air knife side baffle 2.
[0090] The side baffle bracket 101 is provided with a first cavity 10109 and a second cavity 10106. A rectangular second cavity cooling gas pipeline 10105 and a circular second cavity power and signal line pipeline 10104 are provided between the first cavity 10109 and the second cavity 10106. The first cavity 10109 is also provided with a first cavity power and signal line pipeline 10102 for connecting power and electrical signal transmission, and a first cavity cooling gas pipeline 10103 for supplying external cooling gas to cool the equipment in the first cavity 10109 and the second cavity 10106. The first chamber power supply and signal line 10102 and the first chamber cooling gas line 10103 are designed inside the side baffle bracket 101 and are connected through a gas and cable quick connection interface 10101 combination interface set on the top of the side baffle bracket 101. The cable quick connection interface 10101 is a quick connection interface that is easy to disassemble, install and maintain, and maintains the sealed independent connection of the electrical signal transmission and supply cooler pipeline. The purpose of setting the cooling gas source pipeline and the electrical signal transmission line together is to ensure that the internal equipment of the visible air knife slag removal device 1 working above the zinc pot can operate normally under a safe temperature.
[0091] A drive motor 104 is installed inside the first cavity 10109. The drive motor 104 is connected to a motor connecting screw 1041, which drives the motor connecting screw 1041 to rotate. The motor connecting screw 1041 is connected to a rack drive block 1042. When the motor connecting screw 1041 rotates, it drives the rack drive block 1042 to move laterally. A screw retaining ring 1043 is installed at the end of the motor connecting screw 1041. To prevent the rack drive block 1042 from slipping out of the screw range of the motor connecting screw 1041, the rack drive block 1042 is fixedly connected to a rack assembly 1044. The rack assembly 1044... The rack assembly 1044 is equipped with teeth that mesh with a gear 1047 located at the bottom of the side baffle bracket 101. When driven by the rack drive block 1042, the rack assembly 1044 moves laterally, causing the meshing gear 1047 to rotate. The gear 1047 is fixedly connected to a pin 1046. The rotation of the gear 1047 drives the pin 1046 to rotate. The pin 1046 is connected to a triangular strip scraper 1048. The rotation of the pin 1046 causes the triangular strip scraper 1048 to rotate, thus removing the zinc dross adhering to the air knife side baffle 2. The rack assembly 1044 is installed in the rack groove 10107 provided in the first cavity 10109 and the second cavity 10106, allowing for lateral movement. The rack assembly 1044 is installed from inside the second cavity 10106. The gear fixing block 1045 is fixed to the bottom of the side baffle bracket 101 to position the pin 1046 and gear 1047 in the accurate meshing position.
[0092] The second chamber 10106 houses three main devices: a camera 105, a light 106, and a vibrator 107. The angles of both the camera 105 and the light 106 are adjustable. The camera 105 acquires video signals regarding the slag adhesion on the air knife edge baffle 2 and the air knife lip. The severity of the slag adhesion is a necessary condition for activating the front and rear scrapers and the air knife lip cleaning device. The light 106 provides ambient lighting for the air knife edge baffle 2 or the air knife lip during operation. The vibrator 107 works in conjunction with the front and rear scrapers to generate different vibration frequencies on the air knife edge baffle 2, reducing the adhesion of zinc slag on the air knife edge baffle 2 and causing it to fall off.
[0093] The side baffle bracket 101 is equipped with a scraper drive device and electrical signal pipelines and lines arranged symmetrically with the air knife side baffle 2 as the center plane. It also includes cooling pipelines and cavities, as well as lighting, cameras and vibration devices. The drive and zinc dross removal devices arranged on both sides of the air knife side are the same.
[0094] refer to Figure 3 As shown in the top view of the vibrator arrangement, vibrator 107 is located to the left of the lighting lamp 106 and installed inside the second cavity 10106 of the side baffle bracket 101. Vibrator 107 includes a vibrating rod 10701 and a vibrating head 10702, which are fixedly connected. When energized, vibrator 107 generates different vibration frequencies, which act on the inner wall of the second cavity 10106 and transmit the vibration to the air knife side baffle 2. The distance h4 between the vibrating head 10702 and the inner wall of the second cavity 10106 is adjustable. The vibration frequency of vibrator 107 is adjustable, and vibration devices are provided on both sides of the air knife side baffle, which can be driven individually or simultaneously from both sides.
[0095] refer to Figure 4-6 Three views of the side baffle bracket and Figure 7 As shown in the perspective view of the side baffle bracket, the side baffle bracket 101 is mainly a component that connects the side baffle bracket connecting block 103, the air knife side baffle 2, and the scraper assembly to which the air knife side baffle 2 belongs. (Reference) Figure 4 As shown, the side guard bracket connecting groove 101012 is used to connect the side guard bracket connecting block 103, and is installed in an embedded manner. The side baffle T-shaped mounting groove 10108 is arranged inside the side baffle bracket 101 for installing the air knife side baffle 2. The upper part of the side baffle T-shaped mounting groove 10108 has a first positioning hole 101010 and a second positioning hole 101011 for installing the first positioning pin of the side baffle positioning pin 102.
[0096] 1022 and the second positioning pin 1023, the gas and cable quick connection interface 10101 includes two cooling gas pipelines and two power and signal line pipelines, which are respectively connected to the two sides of the air knife side baffle 2. The front first chamber cooling gas pipeline 101031 and the front first chamber power and signal line pipeline 101021 are on the front side of the air knife side baffle 2, and the rear first chamber cooling gas pipeline 101032 and the rear first chamber power and signal line pipeline 101022 are on the rear side of the air knife side baffle 2.
[0097] Cooling gas entering through the gas and cable quick connection interface 10101 passes through the first chamber cooling gas pipeline 10103 and first enters the first chamber 10109 to cool the equipment inside the first chamber 10109. Excess gas enters the second chamber 10106 through the second chamber cooling gas pipeline 10105 to cool the equipment inside the second chamber 10106.
[0098] The power supply and input / output signal lines introduced by the gas and cable quick connection interface 10101 enter the power and signal line conduit 10102 of the first cavity, and enter the equipment power supply and signal input and output inside the first cavity 10109 and the second cavity 10106.
[0099] The bottom of the first cavity 10109 and the second cavity 10106 are provided with rack grooves 10107 for the rear rack groove 1010701 and the front rack groove 1010702.
[0100] refer to Figure 13 As shown in the three-dimensional view of the air knife side baffle, the air knife side baffle 2 adopts a T-shaped design with a T-shaped connecting plate 201, which is vertically installed inside the air knife side baffle bracket 101. The air knife side baffle 2 is installed by a pull-out method. The T-shaped mounting positioning block of the air knife side baffle 2 is designed with two vertically downward circular holes. The bottom of the circular holes adopts a hemispherical structure, which is combined with the cylindrical positioning pin hole 202 and the second positioning pin hole 203 on the side baffle positioning pin 102. The top of the pin is hemispherical, and the hemispherical positioning magnet 1024 matches the positioning hole of the air knife side baffle, so that the air knife side baffle can be accurately fixed and positioned inside the air knife side baffle bracket.
[0101] refer to Figure 9 As shown in the perspective view of the side guard bracket connecting block, two positioning blocks extend outward from the side of the side guard bracket connecting block 103, namely the upper positioning block 1031 and the lower positioning block 1032, which facilitates connection and positioning with the original air knife driving device in the prior art (omitted in this invention).
[0102] refer to Figure 10As shown in the perspective view of the rack assembly, the rack assembly 1044 consists of teeth, a rack, a rack slide plate, and a dust baffle. The rack slider 10441 is an irregularly shaped slider installed inside the rack groove 10107 of the side baffle bracket 101. The rack slider 10441 has a threaded rack drive block mounting hole 10444, which is connected to the rack drive block 1042 by bolts. When the motor connecting screw 1041 rotates, it drives the rack drive block 1042 to move laterally. The rack slider 10441 is fixedly connected to the first dust baffle 10442 and the second dust baffle 10443. The two dust baffles are air-knocked to seal the gap between the rack groove 10107 and the rack slider 10441 in the second cavity 10106 and the first cavity 10109, preventing zinc vapor and zinc dross splashing near the zinc liquid surface from entering the interior and affecting the movement of the rack slider 10441, thus preventing accidental interference. The bottom of the rack slider 10441 is connected to a rack 10445, and the rack 10445 is provided with teeth 10446.
[0103] refer to Figure 11 3D diagram of the second cavity protective cover and Figure 12 As shown in the perspective view of the first cavity protective cover, the second cavity protective cover 101061 is an L-shaped protective cover used to protect the three main devices inside the second cavity 10106—camera 105, lighting lamp 106, and vibrator 107—from high temperatures and the intrusion of other foreign objects. A high-temperature resistant, high-transmittance glass 101062 is installed below the second cavity protective cover 101061, allowing the illumination light generated by the lighting lamp 106 to pass smoothly through the high-temperature resistant, high-transmittance glass and illuminate the air knife edge baffle 2 and the air knife lip, providing light for the camera 105 and compensating for ambient light. This provides better illumination when operators inspect the air knife edge baffle 2 and its surrounding equipment. The first cavity protective cover 101091 is a protective cover for the drive motor and transmission device inside the first cavity 10109. Both the first cavity protective cover 101091 and the second cavity protective cover 101061 are made of thin, heat-resistant stainless steel.
[0104] refer to Figure 14 3D diagram of triangular strip scraper and Figure 15 The schematic diagram of the triangular strip scraper is shown. The triangular strip scraper 1048 is used to remove zinc slag 10483 adhering to the side baffle 2 of the air knife. The triangular strip scraper 1048 is connected to the scraper connecting block 10481. The scraper connecting block 10481 has a square scraper connection positioning hole 10482. The scraper connection positioning hole 10482 is connected to the pin 1046. The rotation of the pin 1046 drives the triangular strip scraper 1048 to rotate. The triangular strip scraper 1048, which is close to the side baffle 2 of the air knife, rotates to remove the zinc slag 10483 adhering to the side baffle 2 of the air knife.
[0105] refer to Figure 16-19 As shown in the three-view drawing and isometric drawing of the visible air knife side baffle cleaning device, the air knife side baffle 2 is installed on the side baffle bracket 101. The rear scraper 10484 driven by the rear gear 104702 and the front scraper 10485 driven by the front gear 104701, arranged on both sides of the air knife side baffle 2, swing to remove the zinc slag 10483 adhering to both sides of the air knife side baffle 2. The driving device and the camera acquisition device used for the front and rear scrapers can operate simultaneously or independently.
[0106] refer to Figure 20-26 As shown, the air knife side baffle 2 of the visible air knife cleaning device 1 and the strip steel 3 have three states: online position, offline position, and cleaning position.
[0107] In the first step, in the offline mode, during the production preparation process, after the air knife is connected to the gas pipeline and circuit connector after being put online, the side baffle of the air knife is in the offline position. The action test is carried out, including the movement of the side baffle of the air knife, the drive of the side baffle scraper device, and whether the power supply, cooling and signal transmission of the camera and lighting device are normal.
[0108] refer to Figure 24 The diagram shows the offline position of the visible air knife edge baffle cleaning device. The offline position refers to the maximum position where the visible air knife cleaning device 1 is moved away from the edge of the strip 3 when the production line is stopped or malfunctioning and unsuitable for using the air knife edge baffle 2. This prevents other abnormal strip steel from scraping against the air knife edge baffle 2. For example, in cases of strip breakage, large thermal wrinkles, or equipment malfunction, the visible air knife cleaning device 1 needs to be moved to the maximum position away from the strip edge to ensure the air knife edge baffle 2 is in normal condition. The distance between the strip 3 and the air knife edge baffle 2 is h1.
[0109] The second step is the online position mode. After the production line starts up and the strip runs, once the air knife is in normal operation, the air knife side baffle starts to move from the offline position to the online position. Adjust the distance and centering between the air knife side baffle and the edge of the strip, and the air knife side baffle will start to be in the online position operation mode.
[0110] refer to Figure 23 The schematic diagram of the visible air knife edge baffle slag removal device is shown. The online position refers to the position during normal production. In order to eliminate the turbulent airflow generated at the edge of the strip due to the action of the air blown out by the air knife on the strip, the distance h between the air knife edge baffle 2 and the edge of the strip 3 is matched according to the type of product produced, the coating thickness, and the production line speed, so as to eliminate the turbulent airflow as much as possible and obtain a coating with a more uniform coating thickness. In particular, it eliminates edge thickness defects and edge zinc slag defects of the strip. It also prevents the air knife edge baffle 2 and the air knife lip from sticking with slag. The part most prone to slag sticking is the horizontal line 4 of the air knife lip, which corresponds to the position where the air knife edge baffle 2 is close to the strip.
[0111] Reference Figure 25 As shown in the schematic diagram of the slag cleaning position of the visual air knife edge baffle slag cleaning device, the slag cleaning position refers to the position where slag needs to be cleaned during normal production. The main judgment basis for the slag cleaning position is that the distance between the strip 3 and the air knife edge baffle 2 is h2, and the distance of h2 is between the on-line position and the off-line position, that is, h < h2 < h1. The slag cleaning position is actually a dynamic range. The starting position of the slag cleaning position is the on-line position. When slag cleaning is required, after receiving the operation instruction of the slag cleaning program, it starts to run from the on-line position towards the off-line position. During the running process, the drive of the slag cleaning device is driven, and after completing the slag cleaning, it returns to the on-line position. Generally, as long as the slag cleaning time is sufficient, the air knife edge baffle 2 will not reach the off-line position. In special cases, when the slag cleaning device fails or the slag cleaning device needs to repeat slag cleaning, it may be necessary for the air knife edge baffle 2 to run to the off-line position to increase the slag cleaning time to ensure that the zinc slag adhered to the air knife edge baffle is completely removed. In order to reduce the slag cleaning time t = v / s of the air knife edge baffle 2, where v is the moving speed of the visual air knife slag cleaning device 1 and s is the moving distance of the visual air knife slag cleaning device 1. Considering that the smaller the slag cleaning time, the shorter the length of the strip that is not covered by the air knife edge baffle at the strip edge, and the better the product quality.
[0112] Reference Figure 26 As shown in the schematic diagram of the three-state layout of the visual air knife edge baffle slag cleaning device, the width of the strip 3 is H. When the air knife edge baffle is in the on-line position, the distance from the strip is h. When the air knife edge baffle 2 is in the off-line position, the distance from the strip 3 is h1. The distance between h and h1 and the distance to the off-line position can both be considered as the slag cleaning position h2. Under the condition of ensuring ideal slag cleaning effect of the air knife edge baffle, reducing the length of the strip that is not covered by the air knife edge baffle can effectively control the length of defective products. The closer h2 is to h, the better. This requires increasing the slag cleaning speed v and reducing the running distance s. The slag cleaning speed v depends on the moving speed of the original air knife edge baffle, that is, the moving speed of the air knife edge baffle drive device in the prior art connected to the side baffle support connection block 103. If the moving speed of the original designed air knife edge baffle drive device is not changed, it is necessary to increase the slag cleaning speed of the edge baffle slag cleaning device in the shortest time. The visual air knife slag cleaning devices 1 on both edges of the strip 3 are symmetrically arranged to control the edge baffles on the working side WS and the drive side DS of the strip 3 respectively.
[0113] In the third step, the edge baffle slag cleaning mode: During normal production, due to the disorder of the air flow or the abnormality of the strip edge, the air flow fluctuation will cause the air knife edge baffle to stick slag, and after sticking slag, the slag is cleaned by the air knife edge baffle slag cleaning device.
[0114] Reference Figure 27-29 As shown in the position of the scraper of the visual air knife edge baffle slag cleaning device
[0115] Reference Figure 27As shown in the original position of the scraper of the visible air knife edge baffle cleaning device, when the perpendicular angle α between the triangular strip scraper 1048 and the pin shaft 1046 is 90°, the triangular strip scraper 1048 is in the original position, that is, the air knife edge baffle 2 is in the offline position.
[0116] refer to Figure 28 As shown in the maximum cleaning position of the scraper of the visible air knife edge baffle cleaning device, when the perpendicular angle b between the triangular strip scraper 1048 and the pin 1046 is 75°-90°, the triangular strip scraper 1048 is at its maximum position. Correspondingly, through the inventor's keen observation, it was found that the slag adhesion position of the air knife edge baffle is usually within 30mm above the horizontal scraping line 4 of the air knife lip and below the horizontal scraping line 4 of the air knife lip. In practical applications, the maximum cleaning angle of the triangular strip scraper 1048 can be reasonably set at the upper part of the slag adhesion position with a 20mm margin, saving cleaning time, increasing cleaning speed, improving product quality, and reducing the length of defective products.
[0117] refer to Figure 29 As shown in the key slag cleaning position of the scraper of the visible air knife edge baffle slag cleaning device, when the perpendicular angle c between the triangular strip scraper 1048 and the pin shaft 1046 is 52°-65°, the triangular strip scraper 1048 is in the key slag cleaning position of the scraper. The slag adhesion is most serious in this angle range, which is also the key point of the camera 105's imaging direction. For the key slag cleaning position of the scraper, it may be necessary to scrape the slag twice to completely remove the adhering zinc slag 10483.
[0118] The fourth step is the air knife blade cleaning mode. If the air knife blade accidentally gets slag stuck to it, the camera will capture a high-definition image to confirm the issue. The air knife can be cleaned using its built-in automatic cleaning device or manually with a scraper. The visual function of the air knife's side baffle can be used to determine the location and severity of the slag, and provide clear feedback on the cleaning effect, thus improving the cleaning effect and efficiency.
[0119] refer to Figure 30 As shown in the diagram of the camera angle adjustment, the camera 105 is positioned to focus on the area of slag adhesion on the edge baffle 2 of the air knife. The camera angle d between the external lens of the camera 105 and the vertical line is 50°-54°, ensuring that the camera 105 can observe the slag adhesion on the entire edge baffle of the air knife and the adjacent air knife blade lip.
[0120] refer to Figure 31As shown in the diagram of the lighting angle adjustment, the lighting direction of the lighting lamp 106 is the area of the key slag-adhering part of the air knife edge baffle 2. The lighting angle e between the lens of the lighting lamp 106 and the vertical line is 47°-52°, ensuring that the lighting lamp 106 can illuminate the slag-adhering part of the entire air knife edge baffle and the adjacent air knife blade lip. This allows for manual handling of slag-adhering parts or inspection of equipment malfunctions under good lighting conditions. Combined with the camera 105, stable and relatively clear high-quality images can be obtained.
