Description

Technical Field

[0001] The utility model relates to the technical field of coating raw material processing, in particular to a powder screening device for coating processing. Background Technique

[0002] Coatings, known as paints in traditional Chinese names, are substances that are applied to the surface of objects to be protected or decorated and can form a continuous film that adheres firmly to the object being coated. They are usually based on resins, oils, or emulsions, with or without the addition of pigments, fillers, and corresponding additives, and are prepared as viscous liquids using organic solvents or water. Coatings can protect the surface of objects from environmental factors (such as water, sunlight, chemicals, corrosion, etc.), extend the service life of objects, improve the appearance of objects, make them more attractive and decorative, and thus enhance the visual effect. Some coatings have special functions, such as fireproof coatings, antibacterial coatings, waterproof coatings, etc., which can be selected according to specific needs.

[0003] During the production process of coatings, in order to improve the fluidity and wear resistance of coatings, powder fillers (such as silica, calcium carbonate, talcum powder, etc.) are usually filled in the coatings. In order to further improve the use effect of coatings, finer powder fillers need to be screened out. Existing screening devices cannot instantaneously adjust the screen size and screening time according to different types of powder fillers, resulting in not only poor screening effects but also the need for additional re-screening, with a poor experience. Therefore, a powder screening device for coating processing is proposed to solve the above-mentioned problems. Content of the Utility Model

[0019] In the embodiment, it is Figures 1-4 given that a powder screening device for coating processing includes a bracket 1 and a feeding hopper 2 arranged on the bracket 1. A movable frame 3 is hinged to the bracket 1 through a hinge. An adjusting assembly 4 is arranged between the bracket 1 and the movable frame 3, which is used to adjust the included angle between the bracket 1 and the movable frame 3. On the side of the movable frame 3 away from the bracket 1, there is a frame body 5, and the frame body 5 is connected to the movable frame 3 through an elastic support member 6. One side of the frame body 5 is open, and a vibration motor 14 is fixedly installed on the other side. A feeding groove 7 communicating with the feeding hopper 2 is opened on the frame body 5. At the top edge of the frame body 5, there is a feeding hopper 8 communicating with the frame body 5. A baffle 9 for controlling the flow rate is arranged at the discharging end of the feeding hopper 8. The bracket 1 is the support for the whole device and is welded by multiple square tubes. The powder filler enters the frame body 5 from the feeding hopper 8. The vibration motor 14 is started to generate high-frequency vibration, which is transmitted to the frame body 5 and the sieve mesh. The sieve mesh generates continuous vibration movement under the action of vibration, making the powder filler form jumping and tumbling on the sieve mesh. Due to the different particle sizes of the powder filler, the larger particles are blocked above the sieve mesh and discharged from the opening of the frame body 5, while the smaller particles fall into the lower feeding hopper 2 through the sieve holes for collection, thereby realizing the screening of the powder filler.

[0020] Referring to Figures 1-4, wherein the adjusting component 4 includes a limiting arm 41 which is fixedly installed on the movable frame 3. A pin 42 with one end penetrating through the support frame 1 is arranged on the support frame 1. A plurality of equally spaced limiting holes 43 are formed in the limiting arm 41, and the limiting holes 43 are adapted to the pin 42;

[0021] With the above structure, when it is necessary to adjust the relative position between the movable frame 3 and the support frame 1, the pin 42 is pulled out from the current limiting hole 43. At this time, the movable frame 3 can move freely relative to the support frame 1. Move the movable frame 3 to the target position, ensure that one of the limiting holes 43 on the limiting arm 41 is aligned with the pin 42, and then insert the pin 42 into the limiting hole 43 for fixation. By adjusting the included angle between the movable frame 3 and the support frame 1, the inclination of the frame body 5 is changed, thereby further changing the screening time of the powder filler in the frame body 5.

[0022] Refer to Figures 1-4 , wherein a screen 10 located above the feeding chute 7 is detachably connected inside the frame body 5. Threaded holes are formed in the screen 10, and locking bolts 11 penetrating through the frame body 5 and adapted to the threaded holes are arranged on the frame body 5;

[0023] With the above structure, the detachable screen 10 can be replaced with different specifications (such as different aperture sizes) according to the screening requirements. The screen 10 is located above the feeding chute 7 and vibrates under the drive of the vibration motor 14 to ensure that the powder filler can be fully screened.

[0024] Refer to Figures 1-4 , wherein the elastic support member 6 includes an upper support seat 61 and a lower support seat 62. The upper support seat 61 and the lower support seat 62 are respectively arranged on the frame body 5 and the movable frame 3, and a telescopic rod 63 is arranged between the upper support seat 61 and the lower support seat 62. A spring 64 is arranged outside the telescopic rod 63, and both ends of the spring 64 are in contact with the upper support seat 61 and the lower support seat 62 respectively;

[0025] Refer to Figures 1-4 , wherein the baffle plate 9 is slidably connected to the discharge end of the feeding hopper 8. A travel hole 12 is arranged on the baffle plate 9, and a hand-tightening nut 13 is arranged in the travel hole 12. Threaded holes matching the hand-tightening nut 13 are formed on the feeding hopper 8;

[0026] With the above structure, by sliding the baffle plate 9, the covering area of the discharge end of the feeding hopper 8 is changed, thereby adjusting the flow rate and speed of the powder filler flowing out of the feeding hopper 8, with stronger flexibility.
