Description

Technical Field

[0001] This utility model relates to the field of metal powder coating production technology, and more specifically, to a screening equipment for color steel plate powder coating. Background Technology

[0002] Metallic powder coatings refer to various powder coatings containing metallic pigments (such as copper gold powder, silver aluminum powder, etc.), which are very suitable for spraying furniture, decorations and automobiles, as well as other indoor and outdoor objects.

[0003] In existing screening equipment, some screens are fixedly installed on the equipment, making disassembly difficult and hindering convenient replacement of screens and quick fixation for use according to the required screening specifications.

[0004] A search revealed a Chinese patent with publication number CN221790043U that discloses a powder coating sieving device for powder coating production. The device features a detachable and replaceable screen, allowing for easy replacement of the screen according to the required powder coating specifications. The design of the insert rod and insertion hole enables the screen to be quickly fixed while the box cover is closed, saving replacement time and improving production efficiency.

[0005] However, in actual use, the above-mentioned paint screening equipment vibrates the screen in a relatively unidirectional direction by the vibrating motor during the screening process of paint powder, which reduces the vibration frequency of the paint powder. This causes the paint to accumulate on the screen surface for a longer period of time, resulting in a decrease in the screening efficiency of the paint powder on the screen surface. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a screening equipment for color steel plate powder coating to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A color steel plate powder coating screening equipment includes a shell, a feed hopper fixedly connected to the top of the shell, two partitions fixedly connected to the inner side of the shell, a collection hopper fixedly connected to the inner side of each partition, a discharge hopper fixedly connected to the bottom of the shell, an outer frame fixedly connected to the bottom of the shell, a collection frame slidably connected to the inner side of the outer frame, and a multi-directional vibration mechanism provided inside the shell. The multi-directional vibration mechanism includes multiple fixed rods, one side of each fixed rod being fixedly connected to the inner wall of the shell, a rotating rod rotatably connected to the inner side of each fixed rod, a connecting rod fixedly connected to the top of each rotating rod, a positioning rod fixedly connected to one side of each connecting rod, and a sleeved outer side of the positioning rod. A spring is included. A telescopic rod is fixedly connected to the top of the spring. A telescopic rod slidably connects to the inner side of the telescopic rod. A fixed seat is rotatably connected to one side of the telescopic rod. The inner side of the telescopic rod is slidably connected to the outer side of the positioning rod. A positioning frame is fixedly connected to one side of the fixed seat. Multiple positioning rods slidably connect to the inner side of the positioning frame. A spring is sleeved on the outer side of the positioning rods 2. A sieve plate is fixedly connected to the top of the positioning rods 2. The bottom of the sieve plate is fixedly connected to the top of the springs 2. A vibration motor is fixedly connected to the bottom of the sieve plate. Two cylinders are fixedly connected to the inner side of the outer casing. A roller is rotatably connected to one end of each cylinder. A dispersion mechanism is provided inside the outer casing.

[0009] By adopting the above technical solution: using two cylinders and rollers to reciprocate the positioning frame, the positioning frame and sieve plate can rotate horizontally on the coating powder. Then, the vibrating motor vibrates the sieve plate up and down, which further sieves the coating powder and improves the vibration frequency and direction of the coating powder.

[0010] As a further description of the above technical solution: the dispersing mechanism includes a second servo motor, the bottom of which is fixedly connected to the top of the outer casing. A rotating plate is fixedly connected to the output end of the second servo motor. The outer side of the rotating plate is rotatably connected to the inner side of the feed hopper. Two second cylinders are fixedly connected to the outer side of the outer casing. A transmission rod is fixedly connected to the top of each second cylinder. Multiple tooth grooves are fixedly connected to both sides of the transmission rod. Gears mesh inside the tooth grooves. A rotating shaft is fixedly connected to the inner side of the gears. The outer side of the rotating shaft is rotatably connected to the inner side of the outer casing. A fixed plate is fixedly connected to the outer side of the rotating shaft. Multiple toothed rods are fixedly connected to the bottom of the fixed plate.

[0011] By adopting the above technical solution: the rotation of the rotating plate is used to quantitatively measure the coating powder entering the shell, and the feed port of the shell is sealed to prevent the coating powder from escaping into the air. Then, through the reciprocating deflection of the two fixed plates and the toothed rod, the coating powder can be dispersed before sieving, so as to increase the initial contact area between the coating powder and the sieve plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up a multi-directional vibration mechanism, compared with the existing technology, the positioning frame can be reciprocated horizontally inside the shell by using a connecting rod, telescopic rod one, telescopic rod two and fixed seat rotation support. Then, the vibrating motor, positioning rod two and spring two vibrate the screen plate in the up and down direction, so that the coating powder can be vibrated in both horizontal and vertical directions, increasing the vibration frequency of the coating powder, thereby improving the screening efficiency of the screening equipment.

[0014] 2. By setting up a dispersing mechanism, compared with the existing technology, the feed amount of coating powder is controlled by the rotation of the rotating plate, and the coating powder to be screened is dispersed by the reciprocating swing of two fixed plates and toothed rods, so that the coating powder can be dispersed into the surface of the screen plate, increasing the initial contact area between a batch of coating powder and the screen plate, thereby speeding up the screening speed and maintaining good screening accuracy.

The inner side of the telescopic rod 14 is connected to the positioning rod 14. The outer side of the 12 is slidably connected, and a positioning frame 17 is fixedly connected to one side of the fixed base 16. Multiple positioning rods 18 are slidably connected to the inner side of the positioning frame 17. A spring 19 is sleeved on the outer side of the positioning rod 18. A sieve plate 20 is fixedly connected to the top of the positioning rod 18. The bottom of the sieve plate 20 is fixedly connected to the top of the spring 19. A vibration motor 21 is fixedly connected to the bottom of the sieve plate 20. Two cylinders 22 are fixedly connected to the inner side of the outer shell 1. A roller 23 is rotatably connected to one end of the cylinder 22. A dispersion mechanism is set inside the outer shell 1. The positioning frame 17 is reciprocated by the two cylinders 22 and the roller 23, so that the positioning frame 17 can swing horizontally under the deflection support of the connecting rod 11, positioning rod 12, telescopic rod 14, telescopic rod 15 and fixed base 16. The vibration motor 21 drives the sieve plate 20 to complete the vertical vibration of the coating powder under the guidance and support of multiple positioning rods 18 and spring 19.

[0025] Reference Figure 1 , Figure 6 and Figure 7As shown, the dispersing mechanism includes a second servo motor 32, the bottom of which is fixedly connected to the top of the outer casing 1. A rotating plate 24 is fixedly connected to the output end of the second servo motor 32. The outer side of the rotating plate 24 is rotatably connected to the inner side of the feed hopper 2. Two second cylinders 25 are fixedly connected to the outer side of the outer casing 1. A transmission rod 26 is fixedly connected to the top of the second cylinder 25. Multiple toothed grooves 27 are fixedly connected to both sides of the transmission rod 26. Gears 28 mesh inside the toothed grooves 27. A rotating shaft 29 is fixedly connected inside the gears 28. The outer side is rotatably connected to the inner side of the outer shell 1. A fixed plate 30 is fixedly connected to the outer side of the rotating shaft 29. Multiple toothed rods 31 are fixedly connected to the bottom of the fixed plate 30. The rotating plate 24 is driven to rotate by the servo motor 22, so that the coating powder can be quantitatively fed and the feed hopper 2 can be closed. Then, the transmission rod 26 is pushed by the cylinder 25, and multiple toothed grooves 27 are used to mesh with the gears 28 on both sides, so that the two fixed plates 30 and the toothed rods 31 can reciprocate and disperse under the drive of the rotating shaft 29.

[0026] The working principle of this utility model is as follows: When screening the coating powder, the coating powder is first placed inside the feed hopper 2. The servo motor 22 is started to drive the rotating plate 24 to rotate. Through the rotation of the rotating plate 24, the coating powder on the top of the rotating plate 24 enters the interior of the outer shell 1. Then, the transmission rod 26 is moved up and down by two cylinders 25. The multiple tooth grooves 27 on both sides of the transmission rod 26 mesh with two gears 28. Then, the multiple gears 28 drive two rotating shafts 29 to deflect up and down. The rotating shafts 29 drive the fixed plate 30 and multiple toothed rods 31 to disperse the coating powder falling from the feed hopper 2. Under the guidance of the partition plate 3 and the collection hopper 5, the coating powder enters the top of the screen plate 20. Then, the two cylinders 22 are started to extend and retract respectively. The extended cylinders 22 drive the rollers 23 to push the outer side of the positioning frame 17. Then, the positioning frame 17 is pushed back and forth, so that the positioning frame 17 drives the outer side. Multiple fixed seats 16 drive the telescopic rods 15 and 14, and provide support for the forward and backward movement of the positioning frame 17 through the connecting rod 11 and the positioning rod 12. This allows the positioning frame 17 to drive the sieve plate 20 to shake the paint powder on top of the sieve plate 20 back and forth. Then, the vibrating motor 21 drives the sieve plate 20 to vibrate. The sieve plate 20 slides and is supported by multiple positioning rods 18 and springs 19, allowing the sieve plate 20 to rotate up and down inside the positioning frame 17. At the same time, the springs 13 on the outside of the positioning rods 12 support the positioning frame 17 itself, reducing the impact of the vibration of the positioning frame 17 on the inner wall of the outer shell 1. Then, the paint powder is screened under the vibration force in both horizontal and vertical directions. Finally, it is guided downward by the partition 4, the collection hopper 5 and the discharge hopper 6 into the collection frame 8 for collection. The screened paint powder can be collected by pulling out the collection frame 8.
