[0030] A working method of a maintenance device for a can-shaped arts and crafts product, comprising the following steps:

[0031] S1: First, place the can-shaped arts and crafts 4 on the top of the bottom plate 1, and start the main motor 8 to make the fixing cotton 11 fit the inner wall of the can-shaped arts and crafts 4 to complete the fixing;

[0032] S2: When the can-shaped arts and crafts 4 is fixed, the spraying mechanism can be driven to move by the adjusting mechanism, so as to adjust the spraying mechanism to a predetermined angle;

[0033] S3: When the angle adjustment of the spraying mechanism is completed, the detection mechanism can be started to detect the material of the current can-shaped arts and crafts 4, and the spraying mechanism can be started;

[0034] S4: The spraying mechanism can start the electric rod 43 according to the detection result of the detection mechanism. When the material of the can-shaped arts and crafts 4 is ceramic, the electric rod 43 can push the upper gear 49 to rotate clockwise and spray the wax inside the left loading tank 41. When the material of the can-shaped arts and crafts 4 is wood, the electric rod 43 can push the upper gear 49 to rotate counterclockwise and spray the wax inside the right loading tank 41.

[0035] Working principle: First, place the can-shaped arts and crafts 4 on the top of the bottom plate 1, and start the main motor 8 to drive the screw rod 14 to rotate. When the screw rod 14 rotates, it can drive the screw tube 17 to move upward by meshing with the threaded tube 17. When the threaded tube 17 moves upward, a number of L-shaped connecting plates 12 can be moved backward by pushing a number of cranks 15. The L-shaped connecting plates 12 can limit the moving trajectory through the limiting plates 13. When the L-shaped connecting plates 12 are active, they can drive the adjacent fixing cottons 11 to move synchronously, so as to fix the inside of the can-shaped arts and crafts 4. When the can-shaped arts and crafts 4 is fixed, the micro motor 23 can be started. The micro motor 23 drives the winding wheel 25 to rotate through the power output shaft. When the winding wheel 25 rotates, the gravity hammer 28 can collide with the outside of the can-shaped arts and crafts 4 without damaging the can-shaped arts and crafts 4 by loosening the pull rope 24.

[0036] Since the rebound force of wood is greater than that of ceramic, if the material of the current pot-shaped arts and crafts 4 is wood, the gravity hammer 28 moves upward in an arc shape under the influence of the rebound force, and drives the slider 27 to start the trigger 31. When the trigger 31 is started, an electrical signal can be transmitted to move the electric pole 43 to the left, and drive the upper gear 49 to rotate clockwise. If the material of the current pot-shaped arts and crafts 4 is ceramic, the rebound force is small, and the gravity hammer 28 will not start the trigger 31. A timer is set inside the trigger 31. If the trigger 31 is not started within the specified time, an electrical signal is transmitted to the electric pole 43 through the timer, so that the electric pole 43 moves to the right, and drives the upper gear 49 to rotate counterclockwise.

[0037] When the upper gear 49 rotates clockwise, the lower gear 50 can be driven to rotate synchronously. The clockwise rotation of the lower gear 50 can drive the linkage rack 48 on the left to move backward. When the linkage rack 48 on the left moves backward, the translation rod 47 is driven to move backward through the adjacent linkage rod 52. The translation rod 47 can spray the wood-specific wax inside the charging tank 41 through the push ring 51. When the upper gear 49 rotates counterclockwise, the ceramic-specific wax on the right can be sprayed out through the above steps.

[0038] When it is necessary to drive the spraying mechanism to move, the main motor 8 can be started to make the fixed cotton 11 separate from the fitting state of the inside of the can-shaped arts and crafts 4, and then the auxiliary motor 9 can be started to drive the sprocket 19 on the right to rotate, and the sprocket 19 on the right can drive the sprocket 19 on the left to rotate through the chain 10, and when the sprocket 19 on the left rotates, the movable tube 21 can be driven to rotate, and when the movable tube 21 rotates, the cross plate 6 can be driven to rotate, thereby driving the spraying mechanism to spray the outside of the can-shaped arts and crafts 4. When the spraying is completed, the main motor 8 can be started again to make the fixed cotton 11 fit the inside of the can-shaped arts and crafts 4, and the auxiliary motor 9 can be started to drive the can-shaped arts and crafts 4 to rotate, and when the can-shaped arts and crafts 4 rotates, it can contact the cleaning cotton 3;

[0039] When the angle of the spraying mechanism needs to be adjusted, the staff can push the U-shaped plate 42 to move. When the U-shaped plate 42 moves, it can move in the inner cavity of the semicircular opening through the two cross plates 35. When the cross plate 35 moves, it can drive the moving block 36 to move. The moving block 36 can drive the clamping block 38 to move. When the clamping block 38 is fitted with the groove, the position of the current spraying mechanism can be fixed.
