[0002] During the production process of hot-dip galvanized steel strip outer plates, Fe, Zn and Al in the zinc liquid in the V-shaped area sandwiched by the steel strip will generate zinc slag (surface slag, floating slag and bottom slag). The generated zinc slag is easy to adhere to the sinking roller and is pressed to the surface of the steel strip by the sinking roller, so that the surface of the steel strip coating often has some defects that look like black spots when observed with the naked eye, which will affect the coating production of automobile plates and the visual effect of the appearance of the parts.

[0009] Furthermore, the scraper mounting rod is connected to a stabilizing plate, and the stabilizing plate is provided with a through hole for the upper end of the ultrasonic vibration amplitude transformer to pass through.

[0010] Furthermore, the stabilizing plate is connected to the scraper mounting rod via two support rods at an angle, and the two support rods and the scraper mounting rod define a closed triangular profile.

[0011] Furthermore, it also includes a baffle, which is arranged on the left and right sides of the scraper and partially extends to the front of the scraper.

[0012] Furthermore, a support platform is provided on the side of the scraper away from the scraper mounting rod, and mounting strips are provided on the left and right sides of the support platform. The baffle is elastically and movably mounted on the mounting strips, and the baffle is subjected to elastic force so as to fit the sinking roller.

[0013] Furthermore, the mounting strip is provided with a first guide hole and a second guide hole at intervals along its length direction, a first guide rod movably arranged in the first guide hole is hingedly provided at the upper end of the baffle plate, a second guide rod movably arranged in the second guide hole is fixedly provided at the upper end of the baffle plate, and the first guide rod and the second guide rod are arranged at intervals along the length direction of the baffle plate; the first guide rod is adapted to the cross-sectional profile of the first guide hole, the second guide hole is a waist-shaped hole, the width of the second guide hole is adapted to the second guide rod, the length direction of the second guide hole is parallel to the length direction of the mounting strip, the first guide rod and the second guide rod are both sleeved with compression springs, the upper end of the compression spring is abutted against the mounting strip, and the lower end is abutted against the baffle plate.

[0014] Furthermore, the sliding frame is provided with a suspension rod, and the middle part of the scraper mounting rod is hinged to the bottom of the suspension rod; the slag removal driving mechanism is a telescopic driving mechanism, one end of which is hinged to the sliding frame, and the other end is hinged to the upper end of the scraper mounting rod.

[0017] The scraper mounting rod is driven by a slag removal driving mechanism to move, thereby driving the blade of the scraper to fit the sinking roller. As the sinking roller rotates, the residue on the surface of the sinking roller is scraped off. Since the sinking roller is immersed in the liquid, an ultrasonic vibrator is used to apply ultrasonic vibration to the scraper, so that the front end of the scraper vibrates at a high frequency to produce a cavitation effect.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0039] Please refer to Figure 1 and Figure 2A slag removal device for a submerged roller in a preferred embodiment of the present invention includes a frame, a sliding frame 100, a scraper mounting rod 200, a scraper 300, an ultrasonic vibrator 400 and a slag removal driving mechanism 500.

[0040] The sliding frame 100 is slidably mounted on the frame along the axial direction of the sinking roller 101 . The sliding frame 100 is connected to a sliding driving mechanism for driving the sliding frame 100 , and the sliding driving mechanism is mounted on the frame.

[0041] The scraper mounting rod 200 is movably mounted on the sliding frame 100. The scraper 300 is mounted on the lower end of the scraper mounting rod 200; the ultrasonic vibrator 400 is used to apply ultrasonic vibration to the scraper 300; the slag removal driving mechanism 500 is mounted on the sliding frame 100, and the slag removal driving mechanism 500 is connected to the scraper mounting rod 200 to drive the scraper mounting rod 200 to move, thereby driving the blade of the scraper 300 to fit the sinking roller 101 or to move away from the sinking roller 101.

[0042] The slag removal device for the submerged roller provided by the present invention utilizes a slag removal driving mechanism 500 to drive the scraper mounting rod 200 to move, thereby driving the blade of the scraper 300 to fit the submerged roller 101. As the submerged roller 101 rotates, the residue on the surface of the submerged roller 101 is scraped off. Since the submerged roller 101 is immersed in the liquid, an ultrasonic vibrator 400 is used to apply ultrasonic vibration to the scraper 300, so that the front end of the scraper vibrates at a high frequency to produce a cavitation effect. The instantaneous high temperature and high pressure generated by ultrasonic cavitation and the pulsed microjet effect are used to sink the residue. The surface of the sinking roller 101 and the zinc liquid loosen the adhesion between the residue and the sinking roller 101, which is more conducive to scraping the residue with a scraper. The ultrasonic vibration is applied to the scraper blade at the same time, so that the scraper 300 vibrates at high frequency along the axial, tangential and circumferential directions of the sinking roller 101, further improving the scraping efficiency of the scraper. The ultrasonic cavitation effect can act on the residue in the small grooves on the surface of the sinking roller 101, so that the residue below the surface of the sinking roller 101 and located in the grooves can be loosened and fall due to the ultrasonic cavitation effect, thereby improving the cleaning effect and cleaning efficiency.

[0043] It is understandable that in some embodiments, the sliding drive mechanism can be a motor, the output shaft of the motor is provided with a gear, and the sliding frame 100 is provided with a rack adapted to the gear, thereby driving the sliding frame 100 to move. There can be various driving forms, such as the output shaft of the motor is connected to the screw rod, and the sliding frame 100 is provided with a nut pair adapted to the screw rod, so as to facilitate the cooperation of the screw rod and the nut pair to achieve transmission. Of course, the sliding drive mechanism can also be other structures, such as the sliding drive mechanism can be a winch or an electric push rod, thereby driving the sliding frame 100 to reciprocate along a straight line. In addition, in order to ensure the smooth sliding of the sliding frame 100, the sliding frame 100 and the frame can be provided with a sliding pair to achieve guidance and sliding stability, for example, a guide column is provided on the frame, and a guide sleeve is provided on the sliding frame 100 to be sleeved on the guide column.

[0044] It is understandable that, in order to facilitate replacement of the scraper 300, the scraper 300 and the scraper mounting rod 200 may be connected via a detachable fastener, thereby facilitating subsequent replacement.

[0045] Reference Figure 1 to Figure 2 In some embodiments of the present invention, the slag removal device also includes an ultrasonic vibration transformer rod 600, and the ultrasonic vibrator 400 is installed at the upper end of the ultrasonic vibration transformer rod 600; the lower end of the ultrasonic vibration transformer rod 600 is located in front of the scraper 300, so that the ultrasonic vibrator 400 can make the lower end of the ultrasonic vibration transformer rod 600 generate ultrasonic vibration, so that the lower end of the ultrasonic vibration transformer rod 600 will vibrate at a high frequency to produce a cavitation effect, so that the bonding between the residue and the sinking roller 101 is loosened, and the residue is loosened due to the action of the ultrasonic vibration transformer rod 600 before contacting the scraper. The loosened residue is more easily scraped off by the scraper, thereby improving the slag removal effect. A support platform 310 is provided on the side of the scraper 300 facing away from the scraper mounting rod 200, and the ultrasonic vibration transformer 600 is fixedly mounted on the support platform 310. The ultrasonic vibration transformer 600 is installed using the support platform 310, so that the ultrasonic vibration transformer 600 can move with the scraper 300, thereby approaching or moving away together, without the need to set up an additional driving mechanism to control the movement of the ultrasonic vibration transformer 600. In addition, the support platform 310 can also enable the ultrasonic vibrator 400 to transmit ultrasonic vibration to the scraper 300, so that the scraping effect and efficiency of the scraper 300 are improved due to the ultrasonic vibration.

[0046] like Figure 4 As shown, a flat portion 620 is provided at the lower end of the ultrasonic vibration horn 600. The flat portion 620 is flat, so that the end can generate high-frequency vibration, thereby increasing the intensity of the cavitation effect.

[0047] Reference Figure 3 and Figure 4 In a further embodiment of the present invention, the ultrasonic vibration horn 600 is provided with an annular groove 610, the support platform 310 is provided with an arc groove for the ultrasonic vibration horn 600 to be embedded, and the end of the support platform 310 is detachably mounted with a shaft cover 320, and the widths of the shaft cover 320 and the support platform 310 are both adapted to the annular groove 610 and partially embedded in the annular groove 610. The axial positioning of the ultrasonic vibration horn 600 is realized by embedding the shaft cover 320 and the support platform 310 into the annular groove 610, and the ultrasonic vibration horn 600 is wrapped by the connection between the shaft cover 320 and the support platform 310 to realize the fixation of the ultrasonic vibration horn 600. Specifically, the shaft cover 320 and the support platform 310 are provided with corresponding holes to be connected and fixed by screws. Of course, the ultrasonic vibration horn 600 can be rotated along its own axis to adjust the position. When the position needs to be adjusted, the screws can be loosened, and the ultrasonic vibration horn 600 can be rotated to the desired position, and then the screws can be tightened.

[0048] Reference Figure 2 and Figure 3 In a further embodiment of the present invention, the scraper mounting rod 200 is connected to a stabilizing plate 210, and the stabilizing plate 210 is provided with a through hole 211 for the upper end of the ultrasonic vibration horn 600 to pass through, thereby playing a role of stabilizing support for the upper end of the ultrasonic vibration horn 600. Since the upper end of the ultrasonic vibration horn 600 is usually higher than the liquid that immerses the sinking roller 101, if there is no stabilizing plate 210, the ultrasonic vibration horn 600 is only connected by the support platform 310 and the shaft cover 320 at the lower end, so that the rear end of the ultrasonic vibration horn 600 is suspended in the air and the structure is unstable. The stabilizing plate 210 plays a good role in stabilizing the rear end of the ultrasonic vibration horn 600, thereby improving the stability of the device.

[0049] Reference Figure 2 and Figure 3 In a further embodiment of the present invention, the stabilizing plate 210 is connected to the scraper mounting rod 200 by two support rods 220 at an angle, and the two support rods 220 and the scraper mounting rod 200 define a closed triangular profile, thereby forming a triangular structure, which makes the structure stable, improves the structural strength, and is not easy to deform or damage as a whole.

[0050] Reference Figures 5 to 7 In some embodiments of the present invention, a baffle 700 is further included. The baffle 700 is arranged on the left and right sides of the scraper 300 and partially extends to the front of the scraper 300, thereby blocking the left and right sides of the front end of the scraper 300 to prevent the scraped residues from falling from the left and right sides to other areas of the sinking roller 101, causing part of the scraped residues to contaminate other areas of the sinking roller 101, thereby ensuring the cleaning effect and avoiding secondary contamination of the slag removal.

[0051] Reference Figure 6 and Figure 7 In a further embodiment of the present invention, a support platform 310 is provided on the side of the scraper 300 away from the scraper mounting rod 200, and mounting strips 330 are provided on the left and right sides of the support platform 310. The baffle 700 is elastically mounted on the mounting strip 330. The baffle 700 is subjected to elastic force so as to fit the sinking roller 101. The elastic activity of the baffle 700 is utilized to make the baffle 700 fit the sinking roller 101 without rigidly contacting the sinking roller 101. The bottom edge of the baffle 700 is chamfered and the bottom surface is smooth to prevent the sharp bottom from scratching the surface of the sinking roller 101.

[0052] Reference Figure 6 and Figure 7In a further embodiment of the present invention, the mounting bar 330 is provided with a first guide hole 331 and a second guide hole 332 at intervals along its length direction, and the length direction of the mounting bar 330 is perpendicular to the axis of the sinking roller 101. A first guide rod 710 movably inserted into the first guide hole 331 is hingedly connected to the upper end of the baffle 700, and the upper end of the baffle 700 is provided on a hinge seat for hinged connection of the bottom of the first guide rod 710, and a second guide rod 720 movably inserted into the second guide hole 332 is fixedly provided on the upper end of the baffle 700, and the lifting and lowering movement and guidance of the baffle 700 are realized by the cooperation between the first guide rod 710 and the first guide hole 331 and the cooperation between the second guide rod 720 and the second guide hole 332. The first guide rod 710 and the second guide rod 720 are spaced apart along the length direction of the baffle 700, that is, the first guide hole 331 and the second guide hole 332, the first guide rod 710 and the second guide rod 720 are spaced apart along the front-to-back direction; the first guide rod 710 is adapted to the cross-sectional profile of the first guide hole 331, the second guide hole 332 is a waist-shaped hole, the width of the second guide hole 332 is adapted to the second guide rod 720, the length direction of the second guide hole 332 is parallel to the length direction of the mounting strip 330, the first guide rod 710 and the second guide rod 720 are both sleeved with a compression spring 730, the upper end of the compression spring 730 is against the mounting strip 330, and the lower end is against the baffle 700. The second guide hole 332 is a waist-shaped hole, so that the second guide rod 720 can not only move along its own axis in the second guide hole 332, but also swing within a certain range. In addition, the first guide rod 710 is hinged to the upper end of the baffle 700, so that the two ends of the baffle 700 can swing and adjust the position within a certain range. Then, by utilizing the effect of the compression spring 730, the baffle 700 can better adapt to the sinking roller 101, ensuring that it can move up and down and swing to adapt to the surface of the sinking roller 101, so as to better fit the sinking roller 101 and ensure the slag blocking effect.

[0053] Reference Figure 6 and Figure 7 In a further embodiment of the present invention, the upper ends of the first guide rod 710 and the second guide rod 720 are both threadedly connected to the limiting nut 740, and the outline of the limiting nut 740 is larger than the diameter of the first guide hole 331 and the width of the second guide hole 332, thereby limiting the movable range of the first guide rod 710 and the second guide rod 720 to prevent the first guide rod 710 and the second guide rod 720 from falling.

[0054] Reference Figure 2 and Figure 3In a further embodiment of the present invention, the sliding frame 100 is provided with a suspension rod 110, and the middle portion of the scraper mounting rod 200 is hinged to the bottom of the suspension rod 110. Specifically, the middle portion of the scraper mounting rod 200 and the bottom of the suspension rod 110 are both provided with hinge ears to achieve hinge connection through a hinge shaft. The slag removal driving mechanism 500 is a telescopic driving mechanism, one end of which is hinged to the sliding frame 100, and the other end is hinged to the upper end of the scraper mounting rod 200. The telescopic driving mechanism can be a telescopic cylinder, and the telescopic cylinder drives the scraper mounting rod 200 to rotate along the hinge, thereby driving the scraper 300 to fit or move away from the sinking roller 101.

[0055] The present invention also provides a method for removing slag from a sinking roller, which is implemented according to the slag removal device of the sinking roller, and includes the following steps: a slag removal driving mechanism 500 drives the scraper mounting rod 200 to move, driving the blade of the scraper 300 to fit the sinking roller 101, an ultrasonic vibrator 400 applies ultrasonic vibration to the scraper 300, driving the end area of ​​the scraper 300 to produce a cavitation effect, and as the sinking roller 101 rotates along its own axis, the scraper 300 removes the residue on the surface of the sinking roller 101; a sliding driving mechanism drives the sliding frame 100 to slide along the axis direction of the sinking roller 101 to remove slag from the surface of the sinking roller 101 section by section, thereby achieving comprehensive slag removal. Ultrasonic cavitation is used to loosen the bond between the residue and the sinking roller 101, which is more conducive to scraping the slag with the scraper and improves the scraping efficiency of the scraper; and the ultrasonic cavitation effect can act on the residue in the small groove on the surface of the sinking roller 101, so that the residue in the groove can be loosened and fall due to the ultrasonic cavitation effect, thereby improving the cleaning effect and cleaning efficiency.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
