The telescopic mechanism 3 is connected to both sides of a rotating mechanism 4 that performs semicircular reciprocating motion, and the rotating mechanism 4 is directly above the hole 11. A conveying hose 14 is arranged above the rotating mechanism 4, and the conveying hose 14 is connected to a first connecting branch pipe 5, a second connecting branch pipe 6, and a third connecting branch pipe 7 below. The three branch pipes are respectively vertically installed on the rotating mechanism 4, and nozzles 8 are installed below the three branch pipes. The conveying hose 14 is connected to a spray pump 13, and the spray pump 12 is connected to the paint tank 13.
[0040] The delivery hose and the spray heads 8 on the first connecting branch pipe 5, the second connecting branch pipe 6 and the third connecting branch pipe 7 below are driven to move up and down and rotate through the telescopic mechanism 3 and the rotating mechanism 4, so that every position of the metal can can be sprayed.
[0041] Furthermore,
[0042] A sparse mesh surface is laid in the hole 11 , and the center of the hole 11 is the placement area 15 . The mesh surface of the placement area 15 is denser than that of other parts. The size of the hole 11 should be smaller than or equal to the size of the recycling box 10 .
[0043] The paint dripping during spraying can enter the collection box 10 through the mesh surface, which can avoid the waste of paint. The mesh surface of the placement area 15 is denser than other parts and can determine the area where the metal can is placed.
[0044] Furthermore,
[0045] Mutually corresponding vertical grooves are formed on the inner sides of the two upright plates 2 .
[0046] The electric telescopic rod 31 can be arranged in the groove and move in a vertical direction.
[0047] Furthermore,
[0048] The telescopic mechanism 3 includes a motor 30, an electric telescopic rod 31, and a connecting block 32. The motor 30 is installed on the upper surface of the vertical plate 2 and directly above the groove. The electric telescopic rod 31 is vertically arranged in the groove and is parallel to the groove. The upper end passes through the upper surface of the vertical plate 2 and is connected to the motor 30. The lower end of the electric telescopic rod 31 is vertically connected to the connecting block 32, and the connecting block 32 and the groove are perpendicular to each other. The length of the connecting block 32 is greater than the depth of the groove. The connecting block 32 extends beyond one side of the groove and is connected to the rotating mechanism 4.
[0049] Because the connecting block 32 is connected to the rotating mechanism 4, the rotating mechanism 4 can be driven by the motor 30 and the electric telescopic rod 31 to move up and down in the vertical direction. The motor 30 is a stepping motor.
[0050] Furthermore,
[0051] The rotating mechanism 4 includes a circular guide rail 40, a slider 41, a cross bar 42, a roller 43, a rotating motor 44, and a connecting rod 45. The circular guide rail 40 is connected to the connecting blocks 32 on both sides. Two sliders 41 are arranged on the circular guide rail 40. A space for accommodating the roller 43 is opened on one side of the slider 41, and the center of the roller 43 is in the space. One end of the roller 43 is in the circular guide rail 40. A rotating motor 44 is installed on the upper surface of the slider 41. The rotating motor 44 is installed with a connecting rod 45. The connecting rod 45 passes through the upper surface of the slider 41 and is connected to the center of the roller 43. A cross bar 42 passing through the center of the circular guide rail 40 is installed between the two sliders 41.
[0052] It is determined that the distance between the two sliders 41 is the farthest on the circular guide rail 40 , and the semicircular motion trajectories of the two sliders 41 have no overlapping parts on the circular guide rail 40 .
[0053] Furthermore,
[0054] The first connecting branch pipe 5 and the second connecting branch pipe 6 respectively penetrate through the two sliders 41 to the same horizontal plane below the sliders 41 , and nozzles 8 are installed inside the first connecting branch pipe 5 and the second connecting branch pipe 6 .
[0055] When the slider 41 is driven by a motor, it can drive the first connecting branch pipe 5, the second connecting branch pipe 6 and the installed nozzle 8 to rotate together.
[0056] Furthermore,
[0057] The third connecting branch pipe 7 passes through the middle of the cross bar 42 to the bottom of the rotating mechanism 4 , and nozzles 8 are installed on both sides and the lower end of the third connecting branch pipe 7 .
[0058] Achieve spraying on the bottom and both sides of the tank.
[0059] Furthermore,
[0060] The left and right spray heads 8 are on the same horizontal line to ensure uniform spraying.
[0061] Furthermore,
[0062] The center of the placement area 15 should correspond to the third connecting branch 7 .
[0063] The metal can is to be placed on the placement area 15, so it is ensured that the third connecting branch pipe 7 can enter the metal can.
[0064] The usage of the utility model is:
[0065] The metal can is placed on the placement area 15 with the metal can in the center of the placement area 15 .
[0066] Then, the motor 30 is started, and the motor 30 controls the electric telescopic rod 31 to drive the connecting block 32 and the circular guide rail 40 to move downward until the third connecting branch pipe 7 is inserted into the metal can to be sprayed and reaches the bottom. At this time, the motor 30 will reverse, drive the electric telescopic rod 31 to retract, and the circular guide rail 40 moves upward. At this time, the spray pump 13 and the rotating motor 43 need to be turned on. The paint pump 13 transports the paint in the paint tank 14 through the conveying hose 14 to the nozzles 8 installed on the first connecting branch pipe 5, the second connecting branch pipe 6, and the third connecting branch pipe 7. The head 8 starts to spray paint, and the rotating motor 44 drives the roller 43 to move on the circular guide rail 40 through the connecting rod 45, and then drives the slider 41 to move together. The slider 41 can drive the first connecting branch pipe 5, the second connecting branch pipe 6, the third connecting branch pipe 7 and the conveying hose 14 to rotate together, and the rotating motor 44 drives each slider 41 to perform a semi-circular reciprocating motion on the circular guide rail 40, and the semi-circular motion path of the two sliders 41 adds up to exactly the circumference of the circular guide rail 40, and there is no repeated part in the paths of the two sliders 41.
[0067] When the metal can is sprayed, turn off all motors and switches and stop spraying.
