[0022] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this utility model belongs.

[0023] Reference Figure 1-4 A feeding device for a reciprocating paint spraying machine includes a hopper 1. The lower surface of the hopper 1 is fixedly connected to support legs 2 distributed in a rectangular array. The lower surface of the hopper 1 is fixedly connected to slide blocks 3 distributed symmetrically. The lower surface of the hopper 1 is fixedly connected to a mounting plate 4. A servo motor 5 is fixedly installed on the back of the mounting plate 4. The output shaft of the servo motor 5 is fixedly connected to a first rotating shaft 6 through a coupling. One end of the first rotating shaft 6 passes through and extends to the front of the mounting plate 4. A driving pulley 7 is fixedly sleeved on the outer surface of one end of the first rotating shaft 6. The servo motor 5 drives the driving pulley 7 to rotate through the first rotating shaft 6.

[0024] The inner wall of the mounting plate 4 is mounted with a second rotating shaft 8 via a bearing. A driven pulley 9 is fixedly sleeved on the outer surface of one end of the second rotating shaft 8. The arrangement of the bearing enables the second rotating shaft 8 to rotate freely.

[0025] Furthermore, the outer surface of the driven pulley 9 is connected to the synchronous belt 10, and the inner wall of the synchronous belt 10 is connected to the outer surface of the driving pulley 7. The servo motor 5 drives the driving pulley 7 to rotate through the first rotating shaft 6. With the cooperation of the second rotating shaft 8, the driving pulley 7 drives the driven pulley 9 to rotate through the synchronous belt 10.

[0026] Furthermore, the outer surface of the synchronous belt 10 is fixedly connected to a connecting block 11, and the inner walls of the two slide blocks 3 are slidingly connected to the two ends of the connecting block 11. The upper surface of the connecting block 11 is fixedly connected to symmetrically distributed push blocks 12, and the upper surface of the push blocks 12 is lower than the upper surface of the bottom wooden board, ensuring that the push blocks 12 only push out the bottom wooden board.

[0027] Furthermore, symmetrically distributed discharge ports 13 are provided on both side surfaces of the silo 1 , one end of the discharge port 13 penetrates and extends to one inner wall of the silo 1 , and the plate pushed by the push block 12 is delivered from the discharge port 13 to the reciprocating paint sprayer.

[0028] Furthermore, a through groove 14 is provided on the lower surface of the silo 1 , one end of the through groove 14 passes through and extends to the inner bottom wall of the silo 1 , and both ends of the through groove 14 are respectively connected to one end of the two discharge ports 13 , and the push block 12 moves in the through groove 14 .

[0029] Furthermore, the inner bottom wall of the silo 1 is provided with mounting grooves 15 distributed in a linear array, and the inner wall of the mounting groove 15 is provided with a roller 16 via a bearing. The setting of the roller 16 can reduce the friction between the wooden board and the bottom of the silo 1.

[0030] Furthermore, symmetrically distributed electric telescopic rods 17 are fixedly installed on the front and back of the silo 1, one end of the electric telescopic rod 17 passes through and extends to the interior of the silo 1, one end of the electric telescopic rod 17 is fixedly connected to a push plate 18, and the front of the push plate 18 is fixedly connected to a symmetrically distributed guide rod 19, one end of the two guide rods 19 passes through and extends to the front of the silo 1, and the movement of the electric telescopic rod 17 drives the two push plates 18 to move relative to each other, squeezing the two sides of the wooden board, so that the wooden board is in the middle position of the silo 1, ensuring that the wooden board delivered to the reciprocating paint sprayer is in the middle position, and the spraying is more uniform and consistent. A discharge plate 20 is fixedly connected to the surface of one side of the silo 1, and one end of the discharge plate 20 is connected to the reciprocating paint sprayer.

[0031] Through the setting of the push plate, this device can adapt to wooden boards of different sizes, so that the boards are in the middle position, making the painting process of the boards more uniform and consistent. In addition, this device can keep the feeding time interval consistent and can adjust the feeding time interval by adjusting the servo motor speed. It is more suitable for automated assembly line operations, improves work efficiency and reduces production costs.

[0032] Working principle: Step 1: Place a stack of wooden boards in the silo 1 and start the electric telescopic rod 17. The two electric telescopic rods 17 are controlled by the control system to start synchronously. With the cooperation of the guide rod 19, the movement of the electric telescopic rod 17 drives the two push plates 18 to move relative to each other, squeezing the two sides of the wooden boards, so that the wooden boards are in the middle position of the silo 1, ensuring that the wooden boards sent to the reciprocating paint sprayer are in the middle position, and the spraying is more uniform and consistent;

[0033] Step 2: Start the servo motor 5, and drive the active pulley 7 to rotate through the first rotating shaft 6. With the cooperation of the second rotating shaft 8, the active pulley 7 drives the driven pulley 9 to rotate through the synchronous belt 10. The synchronous belt 10 drives the push block 12 to move in the through groove 14 through the connecting block 11. The push block 12 drives the bottom plate in the stack of wooden boards to move until the wooden board is sent out from the discharge port 13 through the discharge plate 20. One end of the discharge plate 20 is connected to the reciprocating paint sprayer, so that the wooden board is sent to the reciprocating paint sprayer for spraying. The push block 12 continues to move to the starting position driven by the synchronous belt 10. At this time, the bottom wooden board is sent to the reciprocating paint sprayer. The wooden board that was originally in the second block is at the bottom under the action of gravity. After the above steps, the wooden board is sent to the reciprocating paint sprayer.
