[0011] The adjusting mechanism includes sleeves, fixing holes, L-shaped rods, mounting cavities, connecting springs, sliding plates, locking pins, T-slots, electric telescopic rods, T-blocks, and connecting shafts. Sleeves are symmetrically fixed to the bottom of the top plate. Fixing holes are evenly distributed through the two sleeves on their opposite sides. L-shaped rods are slidably connected through the bottom of the sleeves. Mounting cavities are formed at the top of the opposite sides of the two L-shaped rods.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This quantitative spraying equipment, by starting the motor, drives the turntable to rotate, which in turn causes the connecting rod to deflect, causing the connecting seat to move up and down reciprocally. This, in turn, causes the connecting plate to drive the sealing piston to move up and down reciprocally, pressing the material inside the metering cylinder into the spray head. This ensures that the dosage is the same each time it is sprayed, which facilitates quantitative spraying and avoids spraying too much or too little, thus preventing the impact on the spraying quality.

[0018] 2. This quantitative spraying equipment, when activated, moves the electric telescopic rod, causing the T-block to move. This causes the connecting rod to lift the connecting seat, raising the sealing piston. Then, pressing the locking pin retracts the locking pin, allowing the L-shaped rod to move inside the sleeve. When the locking pin aligns with the fixing hole, it is embedded in the fixing hole, securing the quantitative cylinder. The electric telescopic rod then lowers the T-block, causing the sealing piston to contact the bottom of the quantitative cylinder's inner cavity. This changes the reciprocating stroke of the connecting rod, reducing the stroke of the sealing piston and thus adjusting the spraying amount. This allows for easy application to different workpieces, improving the applicability of the device. Attached Figure Description

[0028] This invention provides a spraying device capable of quantitative spraying, ensuring a consistent dosage for each spray, facilitating precise spraying, and preventing over- or under-spraying to avoid affecting spraying quality. Please refer to [link / reference]. Figure 1-5 It includes a base plate 100, a support rod 200, a top plate 300, a material cylinder 400, and an adjustment mechanism 600;

[0029] Please refer to it again. Figure 1 The support rod 200 is fixedly connected to the top four corners of the base plate 100 for mounting the top plate 300. The top plate 300 is fixedly connected to the top of the support rod 200 for mounting the material cylinder 400. The material cylinder 400 is fixedly connected to the top right of the top plate 300. A connecting pipe 410 is fixedly connected to the bottom middle of the material cylinder 400. A metering mechanism 500 is provided at the bottom of the top plate 300.

[0030] Please refer to it again. Figure 2 The metering mechanism 500 includes a motor 510, a turntable 520, a connecting rod 530, a metering cylinder 540, a first one-way valve 541, a second one-way valve 542, a connecting plate 550, a sealing piston 560, a connecting seat 570, and a nozzle 580.

[0031] Please refer to it again. Figure 2 A motor 510 is fixedly connected to the rear top of the top plate 300. A turntable 520 is fixedly connected to the end of the output shaft of the motor 510. A connecting rod 530 is rotatably connected to the front side of the turntable 520 through an adjustment mechanism 600. A metering cylinder 540 is connected to the bottom of the top plate 300 through the adjustment mechanism 600. A first one-way valve 541 is fixedly connected to the outlet end of the metering cylinder 540.

[0032] Please refer to it again. Figure 2 A second one-way valve 542 is fixedly connected to the inlet end of the metering cylinder 540. A connecting plate 550 is slidably connected inside the metering cylinder 540. A sealing piston 560 is fixedly connected to the bottom of the connecting plate 550. A connecting seat 570 is fixedly connected to the top center of the connecting plate 550. A nozzle 580 is connected to the outlet end of the first one-way valve 541.

[0033] In summary, by starting the motor 510, the turntable 520 is rotated, which causes the connecting rod 530 to deflect and the connecting seat 570 to move up and down reciprocally. This causes the connecting plate 550 to move the sealing piston 560 up and down reciprocally, pressing the material inside the metering cylinder 540 into the nozzle 580. This ensures that the dosage is the same for each spray, facilitating quantitative spraying and preventing over- or under-spraying, thus avoiding affecting the spraying quality.

[0034] Please refer to it again. Figure 2 The input terminal of motor 510 is electrically connected to the output terminal of external power supply, and the inlet terminal of connecting pipe 410 is connected to the inlet terminal of second one-way valve 542.

[0035] Please refer to it again. Figure 2 The outer wall of the sealing piston 560 is tightly fitted with the inner wall of the metering cylinder 540, and the end of the connecting rod 530 is rotatably connected to the inside of the connecting seat 570.

[0036] Please refer to it again. Figure 3-5The adjusting mechanism 600 includes sleeves 610, fixing holes 620, L-shaped rods 630, mounting cavities 640, connecting springs 650, sliding plates 660, locking posts 670, T-slots 680, electric telescopic rods 681, T-blocks 690, and connecting shafts 691. Sleeves 610 are symmetrically fixedly connected to the bottom of the top plate 300. Fixing holes 620 are evenly distributed through the two sleeves 610 on their farthest sides. L-shaped rods 630 are slidably connected through the bottom of the sleeves 610. Mounting cavities 640 are formed at the top of the two L-shaped rods 630 on their farthest sides. The mounting cavities 640 are located on their closest sides. A connecting spring 650 is fixedly connected in the middle, and a sliding plate 660 is fixedly connected to one end of the connecting spring 650. A locking post 670 is fixedly connected in the middle of the two sliding plates 660 on their opposite sides. A T-slot 680 is opened on the front side of the turntable 520. An electric telescopic rod 681 is fixedly connected to the top middle of the T-slot 680. A T-block 690 is fixedly connected to the end of the output shaft of the electric telescopic rod 681. A connecting shaft 691 is fixedly connected to the middle of the front side of the T-block 690. A connecting rod 530 is rotatably connected to the outer wall of the connecting shaft 691. A metering cylinder 540 is fixedly connected to the opposite ends of the two L-shaped rods 630.

[0037] Please refer to it again. Figure 4 The slide plate 660 is slidably connected to the inside of the mounting cavity 640, and the outer side wall of the slide plate 660 is in contact with the inner side wall of the mounting cavity 640.

[0038] Please refer to it again. Figure 5 The input end of the electric telescopic rod 681 is electrically connected to the output end of the external power supply, and the T-block 690 is slidably connected inside the T-slot 680.

[0039] In summary, activating the electric telescopic rod 681 moves the T-block 690, causing the connecting rod 530 to lift the connecting seat 570, which in turn lifts the sealing piston 560. Then, pressing the locking pin 670 retracts the locking pin, causing the L-shaped rod 630 to move inside the sleeve 610. When the locking pin 670 aligns with the fixing hole 620, it is embedded in the fixing hole 620, fixing the metering cylinder 540. Then, the electric telescopic rod 681 moves the T-block 690 downwards, causing the sealing piston 560 to contact the bottom of the inner cavity of the metering cylinder 540. This changes the reciprocating stroke of the connecting rod 530, reducing the stroke of the sealing piston 560, thereby adjusting the amount of coating applied. This makes it suitable for coating different workpieces and improves the applicability of the device.

[0040] In practical use, those skilled in the art place the workpiece at the bottom of the spray head 580, start the motor 510 to rotate the turntable 520, causing the connecting rod 530 to deflect upward from the bottom of the turntable 520. At this time, the connecting rod 530 drives the connecting seat 570 to rise, causing the connecting plate 550 to drive the sealing piston 560 to rise, thereby generating suction. The material inside the material cylinder 400 enters the second one-way valve 542 through the connecting pipe 410 and is sucked into the metering cylinder 540. When the connecting rod 530 deflects downward from the top of the turntable 520, the connecting rod 530 drives the connecting seat 570 to fall, causing the connecting plate 550 to drive the sealing piston 560 to fall, pressing the material into the first one-way valve 541 and into the spray head 580 for metered spraying, completing the spraying process. When it is necessary to change the spraying volume, the electric extension is activated. The retracting rod 681 drives the T-block 690 to rise, causing the connecting rod 530 to drive the connecting seat 570 to rise, which in turn causes the sealing piston 560 to rise. Then, the locking pin 670 is pressed, causing the locking pin 670 to exit the fixing hole 620, which compresses the connecting spring 650, causing the L-shaped rod 630 to rise inside the sleeve 610, driving the metering cylinder 540 to rise. When the locking pin 670 is aligned with the fixing hole 620, the resetting of the connecting spring 650 causes the locking pin 670 to be embedded in the fixing hole 620, fixing the metering cylinder 540. Then, the electric telescopic rod 681 drives the T-block 690 to descend, causing the sealing piston 560 to fit against the bottom of the inner cavity of the metering cylinder 540. This reduces the vertical deflection stroke of the connecting rod 530, reduces the movement stroke of the sealing piston 560, reduces the amount of material sucked in, and changes the amount of spraying.
