[0024] A method for using a coating machine scraper device comprises the following steps:

[0025] S1. When the scraper body needs to be used for coating, the extension ends of the two first cylinders are simultaneously started to extend, and the extension ends of the two first cylinders are used to push the base to move upward, and the movement of the base drives the storage box to move upward, and the movement of the storage box drives the scraper body to move upward, so that the scraper body and the cloth on the surface of the roller shaft are coated;

[0026] S2. When the angle of the scraper body needs to be adjusted, the output end of the first motor is started to rotate, the worm is driven to rotate by the output end of the first motor, the worm is driven to rotate by the rotation of the worm, and then the rotating rod and the storage box are driven to rotate by the rotation of the worm wheel, and the scraper body is driven to rotate by the rotation of the storage box, and the angle of the scraper body is adjusted by adjusting the forward and reverse rotation of the worm;

[0027] S3. When it is necessary to clean the paint on the surface of the scraper body, the output end of the second motor is started to rotate, and the first screw rod is driven to rotate by the output end of the second motor, and the first screw rod is driven to move on the surface of the first screw rod by the rotation of the first screw rod, and the cross plate is driven to move by the movement of the first screw rod. When the first screw rod rotates forward, the first screw nut moves to the rear side, and the cross plate is driven to move backward by the movement of the first screw nut, and the bracket is driven to move by the movement of the cross plate, and the cleaning scraper is driven to move by the movement of the bracket. When the cleaning scraper corresponds to the position of the scraper body, the second motor can be turned off, and the extension end of the second cylinder is started to retract, and the cleaning scraper is driven to move. The extension end of the second cylinder is contracted to drive the mounting frame to move downward, and the movement of the mounting frame drives the cleaning scraper to move. When the cleaning scraper contacts the scraper body, the second cylinder can be closed, and the output end of the third motor is started to rotate. The second screw rod is driven to rotate by the rotation of the output end of the third motor. The second screw nut is moved on the surface of the second screw rod by the rotation of the second screw rod. The second screw nut is moved left and right on the surface of the second screw rod by adjusting the forward and reverse rotation of the second screw rod. The movement of the second screw nut drives the slide plate and the cleaning scraper to move left and right, so that the paint on the surface of the scraper body is cleaned by the left and right movement of the cleaning scraper.

[0028] S3. When the scraper body needs to be disassembled and replaced, the two nuts are removed from the surface of the two screws, and then the connecting plate is detached from the surface of the two screws. Then, the two screws can be taken out of the holder and the block by holding the rear plate, and then the block can be taken out of the holder, so that the scraper body can be replaced conveniently when it is worn, thereby optimizing its ease of use.

[0029] Beneficial Effects

[0030] Compared with the prior art, the advantages of the present invention are:

[0031] (1) In this scheme, when the scraper body is needed for coating, the extension ends of the two first cylinders are started to extend at the same time, and the extension ends of the two first cylinders are used to push the base to move upward, and the movement of the base drives the storage box to move upward, and the movement of the storage box drives the scraper body to move upward, so that the scraper body and the cloth on the surface of the roller shaft are coated.

[0032] (2) In this scheme, when the angle of the scraper body needs to be adjusted, the output end of the first motor is started to rotate, and the rotation of the output end of the first motor drives the worm to rotate, and the rotation of the worm drives the worm wheel to rotate, and then the rotation of the worm wheel drives the rotating rod and the storage box to rotate, and the rotation of the storage box drives the scraper body to rotate. The angle of the scraper body can be adjusted by adjusting the forward and reverse rotation of the worm.

[0033] (3) In this scheme, when it is necessary to clean the paint on the surface of the scraper body, the output end of the second motor is started to rotate, and the first screw rod is driven to rotate by the output end of the second motor. The first screw rod is driven to move the first nut on the surface of the first screw rod, and the movement of the first nut drives the cross plate to move. When the first screw rod rotates forward, the first nut moves backward, and the movement of the first nut drives the cross plate to move backward. The movement of the cross plate drives the bracket to move, and the movement of the bracket drives the cleaning scraper to move. When the cleaning scraper corresponds to the position of the scraper body, the second motor can be turned off, and the extension end of the second cylinder is started to retract. The installation frame is driven downward by contraction of the extended end of the second cylinder, and the cleaning scraper is driven to move by the movement of the installation frame. When the cleaning scraper contacts the scraper body, the second cylinder can be closed. At this time, the output end of the third motor is started to rotate, and the second screw rod is driven to rotate by the rotation of the output end of the third motor. The second nut is moved on the surface of the second screw rod by the rotation of the second screw rod. The second nut is moved left and right on the surface of the second screw rod by adjusting the forward and reverse rotation of the second screw rod. The slide plate and the cleaning scraper are driven left and right by the movement of the second nut, so that the paint on the surface of the scraper body is cleaned by the left and right movement of the cleaning scraper.

[0034] (4) In this solution, when the scraper body needs to be disassembled and replaced, the two nuts are removed from the surfaces of the two screws, and then the connecting plate is detached from the surfaces of the two screws. Then, the two screws can be taken out of the holder and the block by holding the rear plate, and then the block can be taken out of the holder, so that the scraper body can be replaced easily when it is worn, thereby optimizing its ease of use.

[0074] S2. When the angle of the scraper body 16 needs to be adjusted, the output end of the first motor 13 is started to rotate, the worm 12 is driven to rotate by the output end of the first motor 13, the worm wheel 10 is driven to rotate by the rotation of the worm 12, and then the rotating rod 8 and the storage box 7 are driven to rotate by the rotation of the worm wheel 10, and the scraper body 16 is driven to rotate by the rotation of the storage box 7, and the angle of the scraper body 16 is adjusted by adjusting the forward and reverse rotation of the worm 12;

When it is necessary to clean the paint on the surface of the scraper body 16, the output end of the second motor 22 is started to rotate, and the first screw rod 23 is driven to rotate by the output end of the second motor 22. The first screw rod 23 is rotated so that the first nut 24 moves on the surface of the first screw rod 23, and the movement of the first nut 24 drives the cross plate 25 to move. When the first screw rod 23 rotates forward, the first nut 24 moves to the rear side, and the movement of the first nut 24 drives the cross plate 25 to move backward.

When the cleaning scraper 35 corresponds to the position of the scraper body 16, the second motor 22 can be turned off. At this time, the extension end of the second cylinder 29 is started to retract, and the cleaning scraper 35 is moved backward. The installation frame 30 is driven downward by the contraction of the extended end of the second cylinder 29, and the cleaning scraper 35 is driven to move by the movement of the installation frame 30. When the cleaning scraper 35 contacts the scraper body 16, the second cylinder 29 can be closed, and the output end of the third motor 31 is started to rotate. The second screw rod 32 is driven to rotate by the rotation of the output end of the third motor 31.
