Each piston rod 32 and piston reciprocate. A discharge seat 5 is fixedly installed at the other end of the piston cylinder 31. The discharge seat 5 has an installation cavity 51. Several first feed grooves 52 are provided on the top of the discharge seat 5. A material cylinder 4 is fixedly installed on the top of the discharge seat 5, and the first feed grooves 52 are connected to the material cylinder 4.

Several first discharge grooves 53 are provided on the side of the discharge seat 5 near the piston cylinder 31, and the first discharge grooves 53 are connected to the first feed grooves. The first discharge grooves 53 are adapted to the piston cylinder 31. Inside the piston cylinder 31... When the piston moves away from the discharge seat 5, a negative pressure is generated, which draws the paint in the material cylinder 4 into the discharge seat 5 through the first feed groove 52. The suction roller 6 is rotatably installed in the mounting cavity 51. The top of the suction roller 6 is provided with several second feed grooves 61, which are adapted to the first feed groove 52. The side of the suction roller 6 is provided with several second discharge grooves 62, which are adapted to the first discharge groove 53. The second feed grooves 61 and the second discharge grooves 62 are connected, so the paint in the first feed groove 52 can pass through the second feed groove 61, the second discharge groove 62 and the first discharge groove 53 in sequence. The material trough 53 enters the piston cylinder 31. The bottom of the discharge seat 5 is provided with several discharge ports 54. The discharge ports 54 are adapted to the second discharge trough 62. After the suction roller 6 and the piston cylinder 31 have finished suctioning the material, the reversing module can drive the suction roller 6 to rotate 90 degrees, so that the first discharge trough 53 is connected to the second feed trough 61. When the second discharge trough 62 and the discharge port 54, the piston rod 32 and the piston move toward the discharge seat 5, the paint in the piston cylinder 31 can be discharged in sequence through the first discharge trough 53, the second feed trough 61, the second discharge trough 62 and the discharge port 54, and the dispensing can be dispensed into the dispensing tank. The reversing module includes a push plate 71, a guide wheel 72, a push rod 73, a connecting seat 74, and a push block 75. The push plate 71 has an "L"-shaped structure.

That is, the push block 75 has a "C"-shaped structure. The other end of the push plate 71 is hinged to one end of the push rod 73, and the other end of the push rod 73 is hinged to... The connecting seat 74 is fixedly connected to one end of the suction roller 6. When the flywheel 14 rotates and drives the push block 75 to move together, the push block 75 enters the position of the guide wheel 72, which can press down the guide wheel 72. The guide wheel 72 can drive the push plate 71 to swing, so that the push plate 71 swings forward and pushes the push rod 73 to swing forward. The push rod 73 can drive the suction roller 6 to rotate through the connecting seat 74. When the suction roller 6 rotates, the coating flow direction of the dispensing module can be switched.

[0012] The drive module includes a drive motor 11, a transmission mechanism 12, and a reducer 13. The drive motor 11 and the reducer 13 are connected through the transmission mechanism 12. The reducer 13 is fixedly mounted on the frame 1, and the flywheel 14 is fixedly mounted on the output shaft of the reducer 13. The drive motor 11 can drive the flywheel 14 to rotate through the transmission mechanism 12 and the reducer 13. The transmission mechanism 12 can be a pulley belt drive mechanism 12, a chain sprocket drive mechanism 12, etc.

[0013] An adjustment module 2 is provided between the flywheel 14 and the connecting rod 35. The adjustment module 2 includes a guide rail 21, an adjustment screw 22, a knob 23, and a slider 24. The guide rail 21 is fixedly installed in the middle of the flywheel 14. The adjustment screw 22 is rotatably installed inside the guide rail 21. One end of the adjustment screw 22 passes through the guide rail 21 and is equipped with a knob 23. The slider 24 is slidably installed inside the guide rail 21 and is connected to the adjustment screw 22 by a thread. By rotating the knob 23, the position of the slider 24 at the guide rail 21 can be adjusted, thereby adjusting the distance between the slider 24 and the center of the flywheel 14. A connecting post 25 is provided at the slider 24. One end of the connecting rod 35 is rotatably installed on the connecting post 25. Adjusting the distance between the slider 24 and the center of the flywheel 14 can adjust the stroke of the flywheel 14 pushing the connecting rod 35, thereby adjusting the stroke of the piston in the piston cylinder 31, that is, adjusting the amount of paint drawn by the piston cylinder 31.

[0014] The piston rod 32 is slidably inserted into the guide sleeve 33, which is fixedly mounted on the frame 1 by a bracket, thereby enhancing the stability of the piston rod 32 and piston movement.

[0015] The specific implementation process is as follows: When using this paint dispensing device, first inject the paint to be dispensed into the material cylinder 4, then adjust the adjustment module 2. By rotating the knob 23, the position of the slider 24 at the guide rail 21 can be adjusted, thereby adjusting the distance between the slider 24 and the center of the flywheel 14. The connecting column 25 of the slider 24 is rotatably connected to the connecting plate 34. Adjusting the distance between the slider 24 and the center of the flywheel 14 can adjust the stroke of the flywheel 14 pushing the connecting rod 35, thereby adjusting the stroke of the piston in the piston cylinder 31, that is, adjusting the amount of paint absorbed by the piston cylinder 31. Then, the drive motor 11 is started. The drive motor 11 drives the flywheel 14 to rotate through the transmission mechanism 12 and the reducer 13. The flywheel 14 can then drive each piston rod 32 to move together through the connecting rod 35 and the connecting plate 34, pulling the piston rod 32 and the piston backward. At this time, the guide wheel 72 of the reversing module abuts against the bottom of the flywheel 14. The first feed groove 52 of the discharge seat 5 is connected to the material cylinder 4 and the second feed groove 61 of the suction roller 6. The second discharge groove 62 of the suction roller 6 is connected to the first discharge groove 53 of the discharge seat 5 and the piston cylinder 31. When the piston moves backward in the piston cylinder 31, it generates negative pressure, which can sequentially pass the paint in the material cylinder 4 through the first feed groove 52, the second feed groove 61, the second discharge groove 62, and the first discharge groove 53 into the piston cylinder 31 until the piston moves to the end of the drive stroke of the flywheel 14. As the flywheel 14 continues to rotate, the push block 75 at the bottom of the flywheel 14 presses down the guide wheel 72. The guide wheel 72 drives the L-shaped push plate 71 to swing forward, which in turn pushes the push rod 73 forward. The push rod 73, through the connecting seat 74, drives the suction roller 6 to rotate 90 degrees, causing the second feed trough 61 to separate from the first feed trough 52. The side wall of the suction roller 6 blocks the first feed trough 52, and the second feed trough 61 is connected to the first discharge trough 53. The second discharge trough 62 is connected to the discharge port 54. As the guide wheel 72 is pressed down, the flywheel 14 drives the connecting rod 35 to push forward. The piston rod 32 and piston are pushed forward, and the piston can squeeze the paint in the piston cylinder 31, so that the paint in the piston cylinder 31 passes through the first discharge chute 53, the second feed chute 61, the second discharge chute 62, and the discharge port 54 in sequence and is discharged to the discharge seat 5 and enters the dispensing tank for dispensing. The above process is repeated to continuously dispense the paint. Then the piston is squeezed and reset, the guide wheel 72 separates from the push block 75, so that the guide wheel 72 enters the notch of the push block 75, the guide wheel 72 and the bottom of the flywheel 14 are abutted again, the reversing module is reset, and the suction roller 6 is reset.

[0016] This paint dispensing device is driven by a drive module to operate a dispensing module. The dispensing module can suck paint from the material cylinder 4 and, in conjunction with the reversing module, switch the paint flow channel within the dispensing module after the dispensing module has sucked up the paint. Subsequently, the dispensing module extrudes and dispenses the paint into each dispensing tank. This device can quantitatively dispense paint and effectively reduce the paint flow path, reduce paint residue in the dispensing device, and reduce paint waste.
