Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of quick screen replacement structure, and in particular to a quick replacement structure for magnetic powder coating screens. Background Technology
[0002] Powder coatings are solid powdered synthetic resin coatings composed of solid resin, pigments, fillers, and additives. Unlike ordinary solvent-based and water-based coatings, their dispersion medium is air, not solvent or water. They are characterized by solvent-free, 100% film-forming, and low energy consumption. The particle size of powder coatings directly affects the electrostatic adsorption effect and leveling properties during construction. The presence of impurities can form defects such as bumps and particles on the coating surface, affecting the smoothness and evenness of the coating, and reducing its protective performance and decorative effect. Therefore, removing impurities by sieving can effectively reduce coating defects and improve the product yield.
[0003] Magnetic sieves typically consist of a sieve body and magnetic components. The sieve body is woven from metal wire or other materials and has sieve holes of a certain size for screening materials. The magnetic components are generally installed around or inside the sieve and generate a magnetic field to attract magnetic impurities in the material. Early magnetic sieves used magnetic materials with poor performance, resulting in insufficient magnetic field strength. For some weakly magnetic impurities or small magnetic particles, the adsorption effect was not ideal, and the magnetic impurities in the material could not be completely removed, affecting the purity of the material. To solve the problems left over from the early models, spray heads are now installed above or around the magnetic sieves. After screening, the sieve is rinsed with clean water or cleaning solution. Although various cleaning methods can remove most impurities, a small amount of material will still remain in some tiny gaps, corners, and bottoms of the sieve that cannot be cleaned. Over time, this will accumulate. If not cleaned properly, these impurities will enter the product along with new material in the next screening process, causing material contamination. Utility Model Content

However, in some tiny gaps, corners, and bottoms of the screen that cannot be cleaned, these impurities will enter the product along with the new material during the next screening process, resulting in material contamination.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a magnetic powder coating screen quick-change structure, including a protective shell, a screen mesh is internally engaged with the protective shell, a sliding groove is provided on the front side of the outer wall of the protective shell, a sliding piece is slidably connected inside the sliding groove, a sliding block is fixedly connected to the front side of the sliding piece, a connecting block is fixedly connected to the rear side of the sliding piece, a base is fixedly connected to the rear side of the connecting block, two fixing blocks are fixedly connected to the front and rear sides of the top of the base, the two fixing blocks are rotatably connected to the same rotating shaft, a sponge is rotatably connected to the outer wall of the two rotating shafts, screws are threaded to the left side of the two fixing blocks, a storage groove is provided on the left side of the inside of the protective shell, and a fixing mechanism is provided on the front and rear sides of the top of the protective shell.

Two rotating rods are rotatably connected to the left and right sides of the middle of the outer wall of the protective shell. A knob is fixedly connected to the opposite side of each of the two rotating rods. A rotating disk is fixedly connected to the left and right sides of each of the two rotating rods. A fixing strip is fixedly connected to the bottom of the left and right sides of the rotating disk. A fixing groove is opened on the left and right sides of the middle of the screen, and the left and right ends of the fixing strip are rotatably connected to the inside of the fixing groove.
[0008] As a further description of the above technical solution:
[0009] A handle is fixedly connected to the top left side of the outer wall of the protective shell, and a protective sleeve is fixedly connected to the outer wall of the handle.
[0010] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, the sliding block in the sliding groove is manually slid to drive the sliding plate to slide. When sliding, the connecting block and the base are displaced, and the rotating shaft supported by the fixed block on the base moves accordingly. This causes the sponge on the rotating shaft to slide against the bottom of the screen. When the sponge comes into contact with the residual material at the bottom of the screen, it removes the material through its own wiping action, thus cleaning the screen. When the sponge is damaged or seriously dirty, the sponge can be disassembled and replaced by unscrewing the screw on the left side of the fixed block. When it is not needed, it can slide into the storage tank, thereby improving the performance and quality of the product.
[0022] 2. In this utility model, by manually rotating knob one again, knob one drives rotating rod one to rotate. When rotating rod one rotates, it also drives the rotating block at the bottom of rotating rod one to rotate. When the rotating block rotates into the protective shell, the screen can be prevented from falling or shifting position. Then, knob two is rotated, which drives rotating rod two to rotate. The rotating disks on the left and right sides of rotating rod two rotate accordingly. The fixing strip on the rotating disk rotates with the rotating disk and finally rotates into the fixing groove, thereby strengthening the structural stability and the ease of disassembly.

[0030] 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.
[0031] Reference Figure 1 , Figure 2 and Figure 3The system includes a protective shell 1, with a screen 3 internally connected to it. A sliding groove 21 is provided on the front side of the outer wall of the protective shell 1. A sliding piece 6 is slidably connected inside the sliding groove 21. A sliding block 5 is fixedly connected to the front side of the sliding piece 6, and a connecting block 7 is fixedly connected to the rear side of the sliding piece 6. A base 8 is fixedly connected to the rear side of the connecting block 7. When the sliding block 5 is manually slid inside the sliding groove 21, it will drive the sliding piece 6 and the connecting block 7 on the sliding piece 6. The base 8 connected to the connecting block 7 will also move with the sliding piece. Two fixing blocks 9 are fixedly connected to the front and rear sides of the top of the base 8. The two fixing blocks 9 are rotatably connected to the same rotating shaft 10. Sponges 11 are rotatably connected to the outer walls of the two rotating shafts 10. When the fixing blocks 9 support and fix the rotating shafts 10, the rotation of the sponges 11 on the rotating shafts 10 will drive the rotating shafts 10 to rotate together. Both fixing blocks 9 are threaded with screws 12 on their left sides. A storage slot 4 is provided on the left side of the inside of the protective shell 1. When the sponge 11 is damaged or seriously dirty, the sponge 11 can be disassembled and replaced by unscrewing the screws 12. Fixing mechanisms 2 are provided on the front and back sides of the top of the protective shell 1. The fixing mechanisms 2 are used to fix and support the screen 3, thereby improving the stability of the screen structure and its quick disassembly. A button 18 is fixedly connected to the top right side of the outer wall of the protective shell 1. The left side of the button 18 is electrically connected to a light 19. The light 19 can be turned on by the button 18. When the equipment or the screen 3 malfunctions and cannot operate, the light 19 can be turned on to observe the inside. A handle 13 is fixedly connected to the top left side of the outer wall of the protective shell 1. A protective sleeve 14 is fixedly connected to the outer wall of the handle 13. The handle 13 makes it easy to lift the protective shell 1, and the protective sleeve 14 improves the comfort when lifting.
[0032] Specifically, the sliding block 5 in the sliding groove 21 on the front side of the outer wall of the protective shell 1 moves the sliding plate 6, the connecting block 7, and the base 8. The rotating shaft 10 supported by the fixed block 9 on the base 8 moves accordingly, causing the sponge 11 on the rotating shaft 10 to slide against the bottom of the screen 3. When the sponge 11 comes into contact with the residual material at the bottom of the screen 3, it removes the material through its own wiping action, thus cleaning the screen 3. When the sponge 11 is damaged or seriously dirty, the screw 12 on the left side of the fixed block 9 can be turned off and replaced. When the equipment or the screen 3 has a problem and needs to be inspected, the button 18 of the protective shell 1 is pressed, and the light 19 of the button 18 is turned on, illuminating the inside of the protective shell 1, making it easier for the operator to observe the internal condition, find the problem in time, and deal with it. The handle 13 on the outer wall of the protective shell 1 makes it easy for the operator to lift the entire device. The protective sleeve 14 on the outer wall of the handle 13 increases the comfort of the hand when in contact with the handle 13, reduces the discomfort caused by long-term lifting, and makes the device easier to move.
[0033] Reference Figure 3 , Figure 4 and Figure 5 The fixing mechanism 2 includes two rotating rods 201. The outer walls of the two rotating rods 201 are rotatably connected to the front and rear sides of the top of the protective shell 1. A knob 202 is fixedly connected to the bottom of each of the two rotating rods 201, and a rotating block 203 is fixedly connected to the bottom of each of the two rotating rods 201. When the knob 202 is manually rotated, the rotating rods 201 will rotate simultaneously. When the rotating rods 201 rotate, the rotating blocks 203 at the bottom will rotate accordingly, rotating into the interior of the protective shell 1 to prevent the screen 3 from shifting during placement. Two rotating rods 205 are rotatably connected to the left and right sides of the middle of the outer wall of the protective shell 1. A knob 204 is fixedly connected to the opposite side of each of the two rotating rods 205. Rotating the knobs 204... 04 This drives the rotating rod 205. Rotating discs 206 are fixedly connected to the left and right sides of both rotating rods 205. When rotating rods 205 rotate, they simultaneously drive rotating discs 206 to rotate. Fixing strips 207 are fixedly connected to the bottom of the left and right sides of rotating discs 206. Fixing grooves 208 are opened on the left and right sides of the middle of the screen 3. The left and right ends of fixing strips 207 are rotatably connected inside the fixing grooves 208. When rotating discs 206 rotate, they drive fixing strips 207 to rotate and be fixed inside the fixing grooves 208. The fixing mechanism 2 also includes two protective pads 20. Rotating blocks 203 are fixedly connected to the bottom of the two protective pads 20. The protective pads 20 can prevent wear and friction caused by repeated rotation of rotating blocks 203.
[0034] Specifically, by manually rotating knob 202, knob 202 drives rotating rod 201 to rotate, and rotating block 203 at the bottom of rotating rod 201 rotates accordingly. Rotating block 203 rotates into the protective shell 1, which can limit the position of the screen 3 during placement and prevent the screen 3 from shifting. At this time, knob 204 is rotated, which drives rotating rod 205 to rotate. Rotating disk 206 on the left and right sides of rotating rod 205 rotates accordingly. Fixing strip 207 on rotating disk 206 rotates with rotating disk 206. Finally, fixing strip 207 rotates into fixing groove 208, thereby strengthening the fixing effect and enabling quick disassembly. Protective pad 20 on rotating block 203 can reduce wear and friction generated during repeated rotation and protect rotating block 203 and related components.
[0035] Reference Figure 1 and Figure 4The inner wall of the protective shell 1 has two buffer slots 16 on both the left and right sides. The buffer pads 17 are fixedly connected to the left and right sides of the two buffer slots 16. When the screen 3 is placed inside the protective shell 1, it can be squeezed by the buffer pads 17 inside the buffer slots 16 to make the density more compact. It can also prevent vibration when the vibrating motor vibrates. The outer wall of the protective shell 1 is designed with a smooth surface. The outer wall of the protective shell 1 is symmetrically arranged on all four sides. The smooth design can protect the protective shell 1 from external damage.
[0036] Specifically, when the screen 3 is placed inside the protective shell 1, the buffer pad 17 is compressed and deformed. On the one hand, this makes the screen 3 fit more tightly with the inside of the protective shell 1. On the other hand, when the vibrating motor vibrates, the buffer pad 17 absorbs the vibration energy through its own elastic deformation, thus playing a buffering and vibration reduction role, reducing the impact of vibration on the screen 3 and the overall structure. The outer wall of the protective shell 1 adopts a smooth and symmetrical design, which reduces the risk of collision damage caused by uneven surfaces. When external objects collide or rub against it, the smooth surface is not easy to generate scratches and wear, which can effectively protect the structural integrity of the protective shell 1 and extend the service life of the structure.
[0037] Reference Figure 3 and Figure 4 The front side of the sliding block 5 is connected to a protective shell 15. The protective shell 15 is designed in an arc shape. The protective shell 15 can protect the internal sliding block 5 and prevent the sliding block 5 from being damaged by external objects when it is idle.
[0038] Specifically, when idle, the arc-shaped structure can effectively disperse the impact force generated by external collisions, preventing the sliding block 5 from being directly subjected to force, thereby preventing wear, deformation and other damage caused by bumps, playing a protective role for the sliding block 5 and extending its service life.
[0039] Working principle: Before using the device, the sliding block 5 in the sliding groove 21 on the outer wall of the protective shell 1 is manually slid to drive the sliding plate 6 to slide. When sliding, the connecting block 7 and the base 8 are displaced. The rotating shaft 10 supported by the fixed block 9 on the base 8 moves accordingly, so that the sponge 11 on the rotating shaft 10 slides against the bottom of the screen 3. When the sponge 11 comes into contact with the residual material at the bottom of the screen 3, it removes the material through its own wiping action, thus cleaning the screen 3. When the sponge 11 is damaged or seriously dirty, the sponge 11 can be disassembled and replaced by turning the screw 12 on the left side of the fixed block 9, thereby improving the performance and quality of the product.
[0040] Furthermore, by manually rotating knob 202 again, knob 202 drives rotating rod 201 to rotate. When rotating rod 201 rotates, it also drives rotating block 203 at the bottom of rotating rod 201 to rotate. Rotating block 203 rotates into the protective shell 1 to form a fixed baffle. When the screen 3 is placed, it can prevent the screen 3 from falling or shifting its position. At this time, rotating knob 204 drives rotating rod 205 to rotate. Rotating disks 206 on the left and right sides of rotating rod 205 rotate accordingly. Fixing strip 207 on rotating disk 206 rotates with rotating disk 206. Finally, fixing strip 207 rotates into the fixing groove 208, thereby strengthening the structural stability and ease of disassembly.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
