[0001] The invention relates to the technical field of blowing and cleaning devices, in particular to a blowing and cleaning device for a color coating line. Background Art

[0002] The blowing and cleaning device for color coating line is a key equipment to ensure the quality and appearance of coating. It is mainly used to remove dust, iron filings and other impurities attached to the surface of color coated steel plates during the production process to ensure that the surface of color coated steel plates has good paint adhesion when the paint is attached. The blowing and cleaning device for color coating line mainly uses compressed air to spray out at high speed through the nozzle to form a strong airflow to blow off the impurities on the surface of the color coated steel plates.

[0003] In actual use, the existing purge and cleaning device for color coating lines is used because the color coated steel plate is transported along the conveyor belt through the nozzle of the purge and cleaning device. During the passing process, each part of the surface of the color coated steel plate will often only receive one purge, and impurities are likely to float over the nozzle and then fall back to the surface of the color coated steel plate.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a purging and cleaning device for a color coating line is proposed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a purging and cleaning device for a color coating line, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a purging and cleaning device for a color-coated line, comprising a conveyor belt and a purging assembly, a color-coated steel plate is placed on the surface of the conveyor belt, and frames are arranged on both sides of the conveyor belt, the purging assembly is fixed to the surface of the frame, the purging assembly comprises a support frame, a driving motor, a reciprocating screw, a movable sleeve, an air pipe, an air injection hose, a damping shaft, a nozzle, a linkage shaft and a toggle rod, a driving motor is fixed to one side of the support frame, and a reciprocating screw is connected to the output end of the driving motor, a movable sleeve is sleeved on the surface of the reciprocating screw, and an air pipe is fixed to the bottom of the movable sleeve, one end of the air pipe is connected to the air injection hose, and damping shafts are equidistantly distributed on the bottom of the air pipe, a nozzle is connected to the outer wall of the damping shaft, a linkage shaft is connected between the damping shafts, and toggle rods are arranged on the surface of the frame on both sides of the support frame.

[0007] Furthermore, the nozzle is connected to the inside of the air pipe through a conduit, and the nozzle and the damping shaft are arranged one to one.

[0008] Furthermore, the purge assembly also includes a fixed magnet, and a fixed magnet is fixed on the bottom surface of the air pipe above the damping shaft.

[0009] Furthermore, the purge assembly also includes a first rotating magnet, and the first rotating magnet is fixed to one side of the top surface of the nozzle.

[0010] Furthermore, the purge assembly also includes a second rotating magnet, and the second rotating magnet is fixed on the other side of the top surface of the nozzle.

[0011] Furthermore, linkage components are provided at both ends of the reciprocating screw rod, and the linkage components include a first wheel disc and an eccentric rotating shaft, and the outer side surface of the first wheel disc is rotatably connected to the eccentric rotating shaft.

[0012] Furthermore, the linkage assembly also includes a second disc, and the end of the eccentric shaft away from the first wheel disc is rotatably connected to the second disc.

[0013] Furthermore, the linkage assembly also includes an electric telescopic rod, and the outer wall of the eccentric rotating shaft is sleeved with the electric telescopic rod.

[0014] Furthermore, the linkage assembly also includes a force-applying rubber head, and the force-applying rubber head is fixed to the bottom of the electric telescopic rod.

[0016] The present invention provides a purging and cleaning device for a color coating line, which has the following beneficial effects:

[0017] 1. The purging and cleaning device used in the color-coated line uses a driving motor to drive the reciprocating screw to rotate so that the movable sleeve carries the gas pipe and the nozzle to move back and forth, and when the nozzle moves to the end, the toggle rod is used to push and adjust the purging angle, so that the nozzle moves back and forth along the top of the color-coated steel plate for inclined purging, thereby allowing various parts of the surface of the color-coated steel plate to experience multiple purgings of dry hot nitrogen. Multiple purgings at various parts can dry out impurities and enhance the separation effect of impurities, and also minimize the possibility of impurities floating and falling back.

[0018] 2. The purge cleaning device used in the color coating line, when the nozzle moves to the end, it is pushed from the outside to the inside, and the second rotating magnet and the first rotating magnet symmetrically distributed on the top surface of the nozzle will rotate in turn and be replaced in turn. After the replacement, the second rotating magnet or the first rotating magnet is located directly above the damping shaft and adsorbed with the fixed magnet, thereby strengthening the angle fixing effect after the nozzle rotation adjustment, and avoiding the nozzle from rotating at an angle privately due to gravity after being pushed.

[0019] 3. The purging and cleaning device used in the color coating line, when the first disc and the second disc rotate synchronously, the eccentric shaft carries the electric telescopic rod to perform lifting movement, so that the force-applying rubber head applies force to the surface of the color-coated steel plate at a high frequency, causing the surface of the color-coated steel plate to vibrate slightly, thereby enhancing the separation effect of the surface of the color-coated steel plate and impurities, so that the impurities can be blown away from the surface of the color-coated steel plate.

DETAILED DESCRIPTION

[0027] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] like Figure 1-Figure 6As shown, the present invention provides a technical solution: a purging and cleaning device for a color coating line, comprising a conveyor belt 1 and a purging assembly 4, a color coated steel plate 2 is placed on the surface of the conveyor belt 1, and frames 3 are arranged on both sides of the conveyor belt 1, the purging assembly 4 is fixed to the surface of the frame 3, the purging assembly 4 comprises a support frame 401, a drive motor 402, a reciprocating screw rod 403, a movable sleeve seat 404, an air delivery pipe 405, an air injection hose 406, a damping shaft 407, a nozzle 408, a linkage shaft 409 and a toggle rod 410, a drive motor 402 is fixed to one side of the support frame 401, and the output end of the drive motor 402 A reciprocating screw rod 403 is connected, a movable sleeve seat 404 is sleeved on the surface of the reciprocating screw rod 403, and an air pipe 405 is fixed to the bottom of the movable sleeve seat 404, one end of the air pipe 405 is connected to a gas injection hose 406, and damping shafts 407 are evenly distributed at the bottom of the air pipe 405, and nozzles 408 are connected to the outer wall of the damping shaft 407, and a linkage shaft 409 is connected between the damping shafts 407, and the surface of the frame 3 is provided with a toggle rod 410 on both sides of the support frame 401, and the nozzle 408 is connected to the inside of the air pipe 405 through a conduit, and the nozzle 408 and the damping shaft 407 are arranged one to one;

[0029] The specific operation is as follows: the color-coated steel plate 2 is transported on the surface of the conveyor belt 1 along its transmission direction, and the gas injection hose 406 injects the compressed dry hot nitrogen into the gas pipe 405, and the gas pipe 405 sprays the compressed dry hot nitrogen from each nozzle 408 through the conduit, and at the same time, the driving motor 402 drives the reciprocating screw 403 to rotate so that the movable sleeve 404 carries the gas pipe 405 and the nozzle 408 to reciprocate, and the reciprocating movement path of the nozzle 408 is perpendicular to the transmission direction of the color-coated steel plate 2, and the length of the gas pipe 405 is at least twice that of the color-coated steel plate 2. During the uniform transmission of the color-coated steel plate 2, the nozzle 408 reciprocates along the top of the color-coated steel plate 2 and sprays air for purging, thereby allowing various parts of the surface of the color-coated steel plate 2 to undergo multiple purging operations, and the dry hot nitrogen can dry the surface of the color-coated steel plate 2 during the initial purging, so as to dry the impurities on the surface of the color-coated steel plate 2 and then purge and separate them;

[0030] Each time the nozzle 408 moves to the end of the reciprocating screw 403, the toggle rod 410 pushes the side of the nozzle 408 to rotate it through the damping shaft 407, and the damping shafts 407 rotate synchronously through the linkage shaft 409, so that each nozzle 408 is forced to rotate to adjust the blowing angle, so that each nozzle 408 always maintains an inclined angle for blowing during the reciprocating movement, so as to blow away impurities from both sides of the surface of the color-coated steel plate 2;

[0031] Based on the above description, the driving motor 402 is used to drive the reciprocating screw 403 to rotate so that the movable sleeve 404 carries the gas pipe 405 and the nozzle 408 to move back and forth, and when the nozzle 408 moves to the end, the toggle rod 410 is used to push and adjust the purge angle, so that the nozzle 408 moves back and forth along the top of the color-coated steel plate 2 for inclined purge, thereby allowing various parts of the surface of the color-coated steel plate 2 to experience multiple purges of dry hot nitrogen. Multiple purges at various parts can dry out impurities and enhance the separation effect of impurities, and also minimize the possibility of impurities floating and falling back.

[0032] like Figure 1-Figure 6 As shown, the purge assembly 4 further includes a fixed magnet 411, the bottom surface of the gas delivery pipe 405 is fixed with a fixed magnet 411 above the damping shaft 407, the purge assembly 4 further includes a first rotating magnet 412, one side of the top surface of the nozzle 408 is fixed with the first rotating magnet 412, the purge assembly 4 further includes a second rotating magnet 413, the other side of the top surface of the nozzle 408 is fixed with the second rotating magnet 413;

[0033] The specific operation is as follows. Each time the nozzle 408 moves to the end of the reciprocating screw 403, the toggle rod 410 will push the side of the nozzle 408 to make it rotate through the damping shaft 407. Since the nozzle 408 is pushed from the outside to the inside when it moves to the end, the second rotating magnet 413 and the first rotating magnet 412 symmetrically distributed on the top surface of the nozzle 408 will rotate in turn and be toggled and replaced in turn. After the toggle and replacement, the second rotating magnet 413 or the first rotating magnet 412 is located directly above the damping shaft 407 and is adsorbed with the fixed magnet 411, thereby strengthening the angle fixing effect of the nozzle 408 after rotation adjustment, and preventing the nozzle 408 from rotating at an angle privately due to gravity after being pushed.

[0034] like Figure 1-Figure 6 As shown, linkage components 5 are provided at both ends of the reciprocating screw rod 403, and the linkage component 5 includes a first wheel disc 501 and an eccentric shaft 502, and the outer side surface of the first wheel disc 501 is rotatably connected to the eccentric shaft 502, and the linkage component 5 also includes a second disc 503, and the end of the eccentric shaft 502 away from the first wheel disc 501 is rotatably connected to the second disc 503, and the linkage component 5 also includes an electric telescopic rod 504, and the outer wall of the eccentric shaft 502 is sleeved with the electric telescopic rod 504, and the linkage component 5 also includes a force-applying rubber head 505, and the bottom of the electric telescopic rod 504 is fixed with a force-applying rubber head 505, and the force-applying rubber head 505 is located above the color-coated steel plate 2, and the force-applying rubber head 505 is vertically distributed with the color-coated steel plate 2;

[0035] The specific operation is as follows: when the driving motor 402 drives the reciprocating screw rod 403 to rotate, the driving motor 402 first drives the second disc 503 to rotate, and the second disc 503 drives the first wheel disc 501 to rotate through the eccentric rotating shaft 502, and the first wheel disc 501 therefore drives the reciprocating screw rod 403 to rotate. When the first wheel disc 501 and the second disc 503 rotate synchronously, the eccentric rotating shaft 502 carries the electric telescopic rod 504 to perform lifting and lowering movements, so that the force-applying rubber head 505 applies force to the surface of the color-coated steel plate 2 at a high frequency, causing the surface of the color-coated steel plate 2 to vibrate slightly, thereby enhancing the separation effect between the surface of the color-coated steel plate 2 and impurities, so that the impurities are blown away from the surface of the color-coated steel plate 2, wherein the force applied by the force-applying rubber head 505 can be adjusted by the extension and retraction of the electric telescopic rod 504, so as to control the vibration amplitude of the color-coated steel plate 2.

[0036] In summary, when the purging and cleaning device for the color coating line is used, the driving motor 402 first drives the reciprocating screw 403 to rotate, and the driving motor 402 first drives the second disc 503 to rotate, and the second disc 503 drives the first wheel disc 501 to rotate through the eccentric shaft 502, and the first wheel disc 501 thus drives the reciprocating screw 403 to rotate;

[0037] The color-coated steel plate 2 is transported on the surface of the conveyor belt 1 along its transmission direction, and the gas injection hose 406 injects the compressed dry hot nitrogen into the gas pipe 405, and the gas pipe 405 sprays the compressed dry hot nitrogen from each nozzle 408 through the conduit, and at the same time, the driving motor 402 drives the reciprocating screw 403 to rotate so that the movable sleeve 404 carries the gas pipe 405 and the nozzle 408 to reciprocate, and the reciprocating movement path of the nozzle 408 is perpendicular to the transmission direction of the color-coated steel plate 2, and the length of the gas pipe 405 is at least twice that of the color-coated steel plate 2. During the uniform transmission of the color-coated steel plate 2, the nozzle 408 reciprocates along the top of the color-coated steel plate 2 and sprays air for purging, thereby allowing various parts of the surface of the color-coated steel plate 2 to undergo multiple purging operations;

[0038] Each time the nozzle 408 moves to the end of the reciprocating screw 403, the toggle rod 410 pushes the side of the nozzle 408 to rotate it through the damping shaft 407, and the damping shafts 407 rotate synchronously through the linkage shaft 409, so that each nozzle 408 is forced to rotate to adjust the blowing angle, so that each nozzle 408 always maintains an inclined angle for blowing when reciprocating;

[0039] Each time the nozzle 408 moves to the end of the reciprocating screw 403, the toggle rod 410 pushes the side of the nozzle 408 to make it rotate through the damping shaft 407. Since the nozzle 408 is pushed from the outside to the inside when it moves to the end, the second rotating magnet 413 and the first rotating magnet 412 symmetrically distributed on the top surface of the nozzle 408 will rotate in turn and be toggled and replaced in turn. After the toggle and replacement, the second rotating magnet 413 or the first rotating magnet 412 is located directly above the damping shaft 407 and is attracted to the fixed magnet 411, thereby strengthening the angle fixing effect of the nozzle 408 after rotation adjustment.

[0040] When the first wheel disc 501 and the second wheel disc 503 rotate synchronously, the eccentric shaft 502 carries the electric telescopic rod 504 to perform lifting motion, so that the force-applying rubber head 505 applies force to the surface of the color-coated steel plate 2 at a high frequency, causing the surface of the color-coated steel plate 2 to vibrate slightly, thereby enhancing the separation effect between the surface of the color-coated steel plate 2 and impurities, so that the impurities are blown away from the surface of the color-coated steel plate 2. The force applied by the force-applying rubber head 505 can be adjusted by extending and retracting the electric telescopic rod 504, so as to control the vibration amplitude of the color-coated steel plate 2.

[0041] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
