DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Reference Figure 1-Figure 3A vertical steel barrel spraying device comprises a box body 1, a rotating shaft 11 rotatably connected to the box body 1 is provided on the top of the box body 1, a placing plate 2 is fixedly installed on one end of the rotating shaft 11 outside the box body 1, two symmetrically arranged first cylinders 4 are fixedly installed on the top of the placing plate 2, the telescopic ends of the two first cylinders 4 are far away from the rotating shaft 11, and the telescopic ends of the two first cylinders 4 are fixedly installed with abutment blocks 3, a lifting spraying assembly is provided on the top of the box body 1, and the lifting spraying assembly comprises two guide rods 5 fixedly installed on the top of the box body 1, the same fixed plate 8 is fixedly installed on the top of the two guide rods 5, and two second cylinders 7 are fixedly installed on the bottom of the fixed plate 8, and guide blocks 6 are fixedly installed on the telescopic ends of the two second cylinders 7, and the two guide blocks 6 are respectively slidably mounted on the two guide rods 5, and a spray box 9 is fixedly installed between the two guide blocks 6, and a spray head evenly distributed is provided on one side wall of the spray box 9 close to the rotating shaft 11;

[0018] A rotating assembly connected to the lifting and spraying assembly is provided on the box body 1, and the rotating assembly includes a long rod 10 that passes through the top of the box body 1, and one end of the long rod 10 located outside the box body 1 is fixedly connected to the bottom of a guide block 6 thereof, and two telescopic rods 14 are fixedly installed on the inner wall of one side of the box body 1, and blocks 17 are fixedly installed on the telescopic ends of the two telescopic rods 14, and tension springs 18 are fixedly connected between the two blocks 17 and the inner wall of one side of the box body 1, and a displacement block 16 that abuts against the long rod 10 is fixedly installed between the two blocks 17, and a rack 15 is fixedly installed on the side wall of the displacement block 16 close to the rotating shaft 11, and the inner ring of the one-way bearing 12 is fixedly installed on the outer wall of the rotating shaft 11, and the outer ring of the one-way bearing 12 is fixedly installed with a gear 13 meshing with the rack 15, and one end of the long rod 10 located in the box body 1 and the end of the displacement block 16 away from the rotating shaft 11 are both provided with inclined surfaces with the same angle.

[0019] When the utility model is used, the steel drum to be sprayed is placed on the placement plate 2, and the two abutting blocks 3 can be moved away from each other by starting the first cylinder 4, so that they can abut against the inner wall of the steel drum, so that the steel drum is in a fixed state, and then the two guide blocks 6 and the spray box 9 are moved downward by the second cylinder 7 (the spray box 9 is initially located at the highest position). During the downward movement of the spray box 9, a partial area of ​​the steel drum can be sprayed through the nozzle arranged on the spray box 9. During the downward movement of the two guide blocks 6 and the spray box 9, the long rod 10 moves downward accordingly, and the long rod 10 and the displacement block 16 are both provided with inclined surfaces, so that the displacement block 16 can be moved downward first during the downward movement of the long rod 10. It moves in the direction close to the rotating shaft 11, and then maintains this state, the telescopic rod 14 is extended, the tension spring 18 is stretched, and when the displacement block 16 moves in the direction close to the rotating shaft 11, the displacement block 16 drives the rack 15 to move, and through the mutual engagement of the rack 15 and the gear 13, the outer ring of the gear 13 and the one-way bearing 12 (the one-way bearing 12 is a kind of bearing that can rotate freely in one direction and is locked in the other direction) can be rotated around a certain angle in one direction, but at this time the outer ring of the one-way bearing 12 and the inner ring of the one-way bearing 12 are idle, so that the rotating shaft 11 cannot rotate, that is, when the spray box 9 moves downward to spray the steel drum, the steel drum will not rotate;

[0020] Subsequently, the spray box 9 is moved upward by the second cylinder 7. No spraying is performed during the upward movement of the spray box 9. The upward movement of the spray box 9 causes the long rod 10 to move upward. The tension generated by the elongated tension spring 18 can cause the displacement block 16 to move away from the rotating shaft 11 and return to the initial state. By setting the rack 15, the gear 13 and the outer ring of the one-way bearing 12 can be rotated a certain angle in the other direction. At this time, the outer ring and the inner ring of the one-way bearing 12 are locked, and the rotating shaft 11, the placement plate 2 and the steel barrel fixed on the placement plate 2 rotate accordingly by a certain angle. In this way, the steel barrel can be automatically rotated by a certain angle during the upward movement of the spray box 9 to return to the highest position. This reciprocating process can spray the steel barrel evenly.
