Description

Technical Field

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

[0002] Powder coating is a type of coating that exists in the form of solid powder and is widely used for coating metal and non-metal surfaces. Compared with traditional liquid coatings, powder coatings are solvent-free, environmentally friendly, and have low emissions of volatile organic compounds. Their coatings have excellent wear resistance, corrosion resistance, and weather resistance, making them suitable for various fields such as home appliances, automobiles, construction, and furniture.

[0003] Existing screening equipment for powder coating processing does not consider that the screened powder is prone to accumulating and forming blockages, which affects the continuous screening process and requires cleaning. At the same time, the screening equipment cannot conveniently and effectively discharge the screened raw materials, thus making the equipment less practical. Therefore, improvements are needed to address the above problems. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Depend on Figures 1 to 5 The present invention includes a device housing 1, a screening chamber 2 at the top of the device housing 1, and an inverted conical structure at the bottom of the screening chamber 2. A frame plate 3 capable of horizontal reciprocating motion is installed inside the screening chamber 2. Rotatable and adjustable mounting frames 4 are installed on both sides of the bottom of the frame plate 3. Filter screens 5 are installed inside both mounting frames 4. A collection hopper 6 capable of vertical shaking is installed at the bottom of the screening chamber 2. A collection trough 7 communicating with the bottom of the screening chamber 2 is opened on the lower part of one side of the device housing 1. A detachable collection box 8 is installed inside the collection trough 7. A first handle is fixedly installed in the middle of the device. The collection box 8 is located directly below the collection hopper 6. A motor 9 that drives the frame plate 3 is installed on the upper part of one side of the device housing 1. An n-shaped frame 11 is fixedly installed at both ends of the top of the device housing 1. A horizontally movable inverted T-shaped transparent plate 12 is installed inside the two n-shaped frames 11. A second handle is fixedly installed on the top of the two inverted T-shaped transparent plates 12. The inverted T-shaped transparent plates 12 can effectively block and prevent the screening dust from scattering and causing pollution. At the same time, the screening situation can be observed through the inverted T-shaped transparent plates 12.

[0019] Two slide rods 13 are symmetrically fixedly installed in the middle of the screening chamber 2. The surfaces of the two slide rods 13 are movably fitted with movable sleeves 14. The frame plate 3 is fixedly installed between the two movable sleeves 14. One end of each of the two movable sleeves 14 is fixedly connected to the inside of the screening chamber 2 with a rubber corrugated sleeve 15. The surfaces of one end of each of the two slide rods 13 are fitted with springs 16, which are located inside the rubber corrugated sleeves 15. The inside of the screening chamber 2 is rotatably connected to a rotating shaft 17 connected to the output end of the motor 9. Two eccentric extrusion wheels 18 are symmetrically fixedly installed on the surface of the rotating shaft 17. Both eccentric extrusion wheels 18 are in contact with one end of the frame plate 3, thereby effectively driving the frame plate 3 to reciprocate.

[0020] The motor 9 drives the rotating shaft 17 and the two eccentric extrusion rollers 18 to rotate. The rotation of the two eccentric extrusion rollers 18 will squeeze the frame plate 3, causing the movable sleeve 14 to slide on the surface of the slide rod 13 and compress the rubber corrugated sleeve 15 and the spring 16. When the eccentric extrusion rollers 18 stop squeezing the frame plate 3, the elastic restoring force of the rubber corrugated sleeve 15 and the spring 16 will cause the movable sleeve 14 to drive the frame plate 3 to move back on the surface of the slide rod 13. This allows the frame plate 3 to drive the mounting frame 4 and the filter screen 5 to move back and forth continuously. The continuous back and forth movement of the frame plate 3 and the filter screen 5 can effectively perform the screening operation, and the screened powder coating will fall into the collection hopper 6 for collection.

[0021] The top of the movable sleeve 14 is fixedly equipped with a fixing block 19. One end of the two fixing blocks 19 is a pressing inclined structure. Hollow tubes are fixedly installed on both sides of the screening chamber 2. Insert rods 20 are movably inserted into the inside of the two hollow tubes. Rollers 21 that contact the top of the movable sleeve 14 are installed on the top of the two insert rods 20. The bottom of the two insert rods 20 is fixedly connected to the middle of the top two sides of the collection hopper 6. Rubber telescopic rings 22 are fixedly installed between the four sides of the top of the collection hopper 6 and the inside of the screening chamber 2, so as to effectively drive the collection hopper 6 to shake up and down.

[0022] When the moving sleeve 14 moves horizontally back and forth, it will drive the fixed block 19 to move synchronously. The horizontal back and forth movement of the fixed block 19 will squeeze the roller 21 upward through the squeezing inclined structure at its end. The upward movement of the roller 21 will drive the insertion rod 20 and the collection hopper 6 to move upward. At the same time, the fixed block 19 will no longer squeeze the roller 21, so that the collection hopper 6 can fall automatically by its own weight. This allows the collection hopper 6 to effectively shake up and down, so that the powder coating collected inside falls into the collection box 8 for collection and easy export.

[0023] Both ends of the frame plate 3 are provided with inverted T-shaped plates 23 in the middle. The lower part of the two inverted T-shaped plates 23 is provided with horizontal grooves 24. Both ends of the two mounting frames 4 are fixedly installed with T-shaped adjusting pins 25. The T-shaped adjusting pins 25 pass through the horizontal grooves 24. The upper part of the two inverted T-shaped plates 23 and the upper part of the end of the frame plate 3 are threadedly connected with threaded pins 26, so as to effectively discharge the large particles of powder coating remaining on the filter screen 5.

[0024] After the powder coating that meets the requirements is discharged from the inside of the collection box 8, the threaded pin 26 is rotated to separate it from the frame plate 3. Then, the two inverted T-shaped plates 23 can be lowered. The lowering of the two inverted T-shaped plates 23 will drive the two mounting frames 4 to rotate symmetrically and unfold through the horizontal groove 24 and the T-shaped adjusting pin 25. The symmetrical rotation and unfolding of the two mounting frames 4 will cause the large powder coating particles on the surface of the filter screen 5 to fall into the inside of the collection hopper 6 and fall into the inside of the collection box 8 for collection and easy discharge.

[0025] This screening device features a screening and shaking function, which shakes the collected powder during the screening process, preventing the powder from accumulating and allowing it to fall effectively into the collection box for centralized collection. Simultaneously, the device has a convenient detachable and adjustable structure, which effectively removes larger powder particles after screening, thereby improving the performance of the screening device. Furthermore, the device has a simple structural design, is easy and convenient to use and operate, and is stable and reliable. Its practicality meets the needs of powder coating screening and processing.
