Description

Technical Field

[0001] This utility model relates to the field of powder coating technology, specifically to a powder coating feeding device. Background Technology

[0002] Powder coating is a form of coating that does not contain liquid solvents. It consists of solid resins, pigments, fillers, and additives, which are processed into a very fine powder. Unlike traditional solvent-based or water-based coatings, powder coatings use air as the dispersion medium, meaning that no volatile organic compounds are released during use, thus reducing environmental impact.

[0003] However, during the process of adding powder coating to the feeding container, a large amount of dust will be released into the air, causing a large amount of dust to accumulate in the work area. This will not only affect the normal operation of the equipment, but also pollute the working environment and endanger the health of the operators. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0022] Combination Figure 1 A powder coating feeding device includes a frame 1 and a feeding tank 2 slidably connected inside the frame 1. The upper surface of the feeding tank 2 is provided with a tank cover 21, the bottom of the feeding tank 2 is provided with a conveying pipe 22, and the inner wall of the feeding tank 2 is provided with a blocking component 3 for preventing powder from flying.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example 1:

[0025] Please see Figures 1-4 The blocking assembly 3 includes a feed frame 31 disposed on the upper surface of the can lid 21, and a baffle plate 32 hinged to the inner wall of the feed frame 31. An electric push rod A33 is hinged to the inner wall of the feed frame 31, and the telescopic end of the electric push rod A33 is hinged to one side of the baffle plate 32. The feeding tank 2 is provided with a wind box 34, a dust-blocking plate 35 is disposed on one side of the wind box 34, and a fan 36 is disposed on the inner wall of the wind box 34. When it is necessary to add material to the feeding tank 2, one end of the bagged powder coating is placed into the feed frame 31. 1. Then, the extension of the electric push rod A33 is controlled to drive the rotation of the baffle plate 32, thereby controlling the feeding rate and reducing powder flying. At the same time, the blower 36 is started to continuously suck up the powder coating, causing it to sink quickly. Since a dust blocking plate 35 is provided on one side of the blower box 34, it can prevent the material from overflowing from the blower box 34, thus significantly reducing the flying phenomenon of powder coating during the addition process, improving the working environment, and reducing potential health hazards to workers.

[0026] A transparent dust cover 4 is hinged to the outer surface of the feed frame 31. When feeding, the transparent dust cover 4 is rotated and placed on the upper surface of the bagged powder coating, which not only further prevents dust from flying, but also makes it easy to observe.

[0027] The inner wall of the feeding tank 2 is provided with an anti-stick coating 5, which is a component made of epoxy resin to reduce the adhesion of powder coating on the inner wall of the feeding tank 2.

[0028] A motor 6 is fixedly installed on the upper surface of the can lid 21. A stirring shaft 61 is fixedly installed at the output end of the motor 6. One end of the stirring shaft 61 passes through the can lid 21, and a stirring paddle 62 is fixedly sleeved on the outer surface of the part of the stirring shaft 61 that passes through. The motor 6 drives the stirring shaft 61 and the stirring paddle 62 to rotate, thereby preventing the powder coating from clumping.

[0029] A spring 7 is provided on the upper surface of the frame 1. A connecting block 71 is fixedly installed on the upper end of the spring 7. One side of the connecting block 71 is fixedly connected to the outer surface of the feeding tank 2. A slide groove 11 is provided on one side of the frame 1. An electric push rod B72 is fixedly installed on the inner wall of the slide groove 11. A slider 73 is fixedly installed on the telescopic end of the electric push rod B72. One side of the slider 73 is fixedly connected to the outer surface of the feeding tank 2. The telescopic movement of the electric push rod B72 causes the feeding tank 2 to vibrate up and down, thereby helping the material to flow better and avoiding adhesion to the tank wall. The spring 7 can buffer this movement, making the movement of the feeding tank 2 smoother and reducing impact.

[0030] The bottom of the feeding tank 2 is provided with a feeding hopper 8, and the inner wall of the feeding hopper 8 is provided with a screen plate 81. One end of the conveying pipe 22 is connected to the bottom of the feeding hopper 8, and a solenoid valve 82 is provided through the outer surface of the conveying pipe 22. The screen plate 81 in the feeding hopper 8 can prevent large particles or clumps of powder coating from flowing into other equipment, and the solenoid valve 82 controls the flow of materials.

[0031] The outer surface of the feeding tank 2 is provided with a viewing window 9, and a scale 91 is provided on one side of the viewing window 9, so that the operator can see the amount of material in the tank and replenish it in time.

[0032] Specifically, when adding material to the feed tank 2, one end of the bagged powder coating is placed into the feed frame 31, and the transparent dust cover 4 is rotated to cover the upper surface of the bagged powder coating. Then, the extension of the electric push rod A33 is controlled, which drives the rotation of the baffle plate 32, thereby controlling the feeding rate and reducing powder scattering. This also facilitates observation. At the same time, the blower 36 is started to continuously draw in the powder coating, causing it to settle quickly. Since a dust baffle plate 35 is provided on one side of the blower box 34, it prevents material from overflowing from the blower box 34, thus significantly reducing the scattering of powder coating during the addition process, improving the working environment, and reducing potential health hazards to workers. Then, the motor 6 drives the stirring shaft 61 and the stirring paddle 62 to rotate, thereby preventing the powder coating from clumping. The extension and retraction of the electric push rod B72 causes the feeding tank 2 to vibrate up and down, thereby helping the material to flow better and preventing it from sticking to the tank wall. In addition, the spring 7 can buffer this movement, making the movement of the feeding tank 2 smoother and reducing impact. Then, the solenoid valve 82 is opened, so that the powder coating flows into other equipment through the discharge hopper 8 and the conveying pipe 22. Because the inner wall of the discharge hopper 8 is equipped with a sieve plate 81, large particles or clumps of powder coating can be prevented from flowing out. At the same time, because the inner wall of the feeding tank 2 is equipped with an anti-stick coating 5 made of epoxy resin, the adhesion of powder coating to the inner wall of the feeding tank 2 can be reduced. Finally, because the outer surface of the feeding tank 2 is equipped with a viewing window 9, and one side of the viewing window 9 is equipped with a scale 91, the operator can see the amount of material in the tank and replenish it in time.
