[0025] Example 1: as Figure 1 - Figure 7The utility model provides a kind of technical scheme shown in the utility model discloses a kind of powder coating precision metering feeding machine, including bunker 1 and conveyor 2, the surface of conveyor 2 is fixedly connected with discharge pipe 3, the top of discharge pipe 3 is fixedly connected with bunker 1, the surface of bunker 1 is fixedly connected with feed hopper 4, the surface of bunker 1 is equipped with square groove 6, the bottom of square groove 6 is equipped with slot 7, slot 7 is inserted with square box 8 inside, the inside bottom surface of square box 8 is equipped with filter hole 21, the surface of square box 8 is fixedly connected with clamping block 11, the surface of bunker 1 is fixedly connected with fixed block 10, the inside screw thread of fixed block 10 is connected with screw rod 12, one end of screw rod 12 is inserted in the inside of clamping block 11, the other end of screw rod 12 is fixedly connected with knob 13, the inside of conveyor 2 is transversely provided with spiral conveying rod 24, the surface of conveyor 2 is fixedly connected with motor 23, the output of motor 23 is fixedly connected with spiral conveying rod 24, the surface of conveyor 2 can be fixedly connected with discharge pipe 15, the surface of bunker 1 is fixedly connected with vibrator 9, the bottom of bunker 1 is fixedly connected with weighing sensor 20, the number of screw rod 12 is two groups, two groups of screw rod 12 are symmetrically distributed on the surface of bunker 1 in the middle of two sides, the surface of knob 13 is fixedly connected with anti-skid rib 14, anti-skid rib 14 is evenly distributed on the surface of knob 13, the surface of square box 8 is sleeved with sealing washer 22, sealing washer 22 is located in the inside of square groove 6, the surface of bunker 1 is embedded with observation window 5, and observation window 5 is made of transparent and wear-resistant material.

[0026] In the embodiment, through the filter hole 21 in the square box 8, the powder coating added into the bunker 1 through the feed hopper 4 is filtered, which can effectively remove various impurities mixed therein, so that the powder coating entering the production equipment has high purity, thereby significantly improving the product surface coating quality, avoiding quality problems such as surface particles and uneven color caused by impurities, and avoiding the blockage of the powder coating accumulated in the square box 8 by transmitting vibration through the vibrator 9. By rotating the knob 13, the knob 13 drives the screw rod 12 to rotate in the fixed block 10, so that one end of the screw rod 12 is separated from the inside of the clamping block 11, which facilitates the removal of the square box 8 from the bunker 1 for centralized treatment of impurities in the square box 8. By the anti-skid rib 14 on the knob 13, the friction force can be increased when rotating the knob 13 to avoid slipping. By the sealing washer 22, the sealing property between the square box 8 and the square groove 6 can be improved to avoid coating leakage. Through the observation window 5, the volume of the powder coating added into the bunker 1 can be grasped to avoid excessive addition of coating or timely replenishment according to the remaining amount of the powder coating in the bunker 1.

[0027] Example 2: as Figure 6As shown, the inside bottom surface of the bin 1 is provided with a discharge port 16, the bottom of the bin 1 is fixedly connected with a U-shaped frame 17, the inner side of the U-shaped frame 17 is slidably connected with a baffle 18, the baffle 18 is located below the discharge port 16, the bottom of the bin 1 is fixedly connected with an electric push rod 19, and the output end of the electric push rod 19 is fixedly connected with the baffle 18.

[0028] In the embodiment, the baffle 18 is moved by the output end of the electric push rod 19, the purpose of sealing the discharge port 16 is achieved, compared with some traditional discharge control modes such as manual valves, the operation is more convenient and labor-saving, and can be remotely controlled or operated on a human-machine interface, without the need for direct manual operation at the bottom of the bin 1, the safety and convenience of operation are improved, and the opening size of the discharge port 16 can be controlled, so as to control the discharge amount of the powder coating.

[0029] The working principle of this embodiment is as follows: During use, powder coating is first added to the hopper 1 through the feed hopper 4. Simultaneously, the vibrator 9 is activated, generating a certain vibration frequency that is transmitted to the square box 8, causing the powder coating inside the square box 8 to vibrate and tumble. This allows the powder coating to quickly pass through the filter holes 21 and fall to the bottom of the hopper 1. Various impurities remain inside the square box 8, resulting in high purity powder coating entering the production equipment. This significantly improves the surface coating quality of the product and avoids quality problems such as surface particles and uneven color caused by impurities. The dense... The sealing gasket 22 prevents paint from leaking out from the gap between the square box 8 and the square groove 6. When it is necessary to clean the impurities inside the square box 8, turn the knob 13. The anti-slip ribs 14 on the knob 13 can increase the friction when rotating the knob 13 to prevent slippage. The knob 13 drives the screw 12 to rotate inside the fixing block 10, causing one end of the screw 12 to disengage from the locking block 11. Then, the square box 8 can be removed from the groove 7, making it easier to remove the square box 8 from the hopper 1 later for centralized treatment of the impurities inside the square box 8. Continuously add to the hopper 1 During powder coating, the volume of powder coating added to the hopper 1 can be monitored through the observation window 5 to prevent overfilling or to replenish the powder coating in the hopper 1 as needed. When powder coating needs to be added to the processing equipment, the electric push rod 19 is activated. The output end of the electric push rod 19 drives the baffle 18 to slide inside the U-shaped frame 17, opening the discharge port. This process achieves the purpose of opening and closing the discharge port 16. Compared with some traditional manual valves and other discharge control methods, this method is simpler and less labor-intensive, and can be remotely controlled or integrated into the human-machine interface. The operation is performed via the interface, eliminating the need for manual operation at the bottom of the hopper 1, thus improving safety and convenience. The opening of the discharge port 16 can also be controlled to regulate the amount of powder coating discharged. Then, the motor 23 on the conveyor 2 is started, driving the screw conveyor 24 to rotate, causing the powder to fall into the processing equipment through the discharge pipe 15. By monitoring the weight of the hopper 1 and controlling the rotation speed of the screw conveyor 24 using the weighing sensor 20, the amount of coating added to the processing equipment can be precisely controlled, preventing excessive addition of coating.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
