After completion, the protective cover must be closed. The device needs to be disassembled and cleaned manually on a regular basis, which increases the complexity of the operation and reduces work efficiency. In order to solve the above technical problems, we have designed a multifunctional rubber powder grading and screening device. Utility Model Content

A guard plate 5 is fixedly installed on the top of the inclined plate 31. By setting the guard plate 5, the powder entering the inclined plate 31 is not easy to spill, and the internal structure of the device can be protected from damage. The inner cavity of the guard plate 5 is fixedly connected with a cleaning component 6, and a cover plate 7 is movably connected to one side of the top of the guard plate 5. By setting the cover plate 7, dust can be effectively blocked from entering the interior of the cleaning component 6, so as to better protect the device. The top of the guard plate 5 is fixedly connected with a crushing component 8.

[0022] See also Figure 2 , Figure 3 and Figure 4 The inner cavity of the inclined plate 31 is sequentially installed with a secondary screen 33 and a primary screen 34. By setting the secondary screen 33 and the primary screen 34, the screening is graded to better separate powders of different particle sizes and apply the powders of different particle sizes to suitable places. A discharge trough 32 is fixedly installed on one side of the inclined plate 31, and a funnel 35 is installed at the bottom of the inclined plate 31. By setting the funnel 35, the screened powder can be better concentrated together for easy collection.

[0023] See also Figure 2 and Figure 3 The secondary sieve 33 and the primary sieve 34 are made of the same material, the mesh diameter of the secondary sieve 33 is larger than the mesh diameter of the primary sieve 34, and the funnel 35 is fixedly installed at the bottom of the secondary sieve 33 and the primary sieve 34 respectively.

[0024] See also Figure 1 , Figure 4 and Figure 5 The cleaning assembly 6 includes a sliding plate 67 and a fan 64. The sliding plate 67 is fixedly installed on the top of the inclined plate 31. By setting the sliding plate 67, not only can the penetrating hard tube 65 be moved left and right, but also the working area can be effectively separated. The fan 64 is fixed on the surface of the guard plate 5. The air outlet end of the fan 64 is connected with a telescopic hose 63, and the other end of the telescopic hose 63 is connected with the hard tube 65. The bottom of the hard tube 65 is connected with a thin tube 66. One end of the hard tube 65 penetrates and is connected to the inner cavity of the sliding plate 67. A slide plate 68 is sleeved on the surface of the left side of the hard tube 65. The slide plate 68 is fixedly connected to the surface of the inner wall of the guard plate 5. Baffles 61 are fixedly installed on the front and rear sides of the bottom of the hard tube 65.

[0025] See also Figure 1 and Figure 4 A linear motor 62 is fixedly installed on the left side of the sliding plate 67. By setting the linear motor 62, the hard tube 65 fixedly connected to the moving end thereof can move left and right, which is convenient for cleaning, so that the entire mesh area can be covered and the operating range is wider. The hard tube 65 is fixedly connected to the surface of the moving end of the linear motor 62.

[0026] See also Figure 1 The crushing assembly 8 includes a bracket 81 and a feed trough 84. The bracket 81 is fixedly connected to one side of the surface of the guard plate 5, and the feed trough 84 is fixedly installed on the right side of the top of the guard plate 5. The top of the bracket 81 is fixedly connected to a motor 82. The output shaft of the motor 82 passes through the inner cavity of the feed trough 84 and is fixedly connected to a crushing rod 83. By setting the crushing rod 83, the rubber powder that enters the feed trough 84 and is electrostatically clustered can be crushed and can be better screened after falling into the inclined plate 31.

[0027] When in use, the rubber powder is poured into the feed trough 84. When the rubber powder passes through the feed trough 84, it passes through the crushing rod 83. The motor 82 rotates to drive the crushing rod 83 to rotate, so that the rubber powder that is easy to electrostatically agglomerate is crushed and falls into the inclined plate 31 below. The vibration motor 4 runs to make the whole device vibrate. The rubber powder that falls into the inclined plate 31 slides downward under the combined action of gravity and the vibration motor 4. When passing through the primary screen 34, the particles smaller than the screen directly fall into the funnel 35 below, and then are collected together. The rubber powder that has not fallen continues to slide on the inclined plate 31. When passing through the secondary screen 33, the particles smaller than the screen directly fall into the funnel 35 below, and then are collected together. The powder continues to slide on the inclined plate 31 and finally falls into the discharge trough 32 for centralized collection, thus forming a graded screening effect; since the rubber powder will pierce into the mesh holes like fibers and block the mesh holes, the fan 64 fixed on the surface of the guard plate 5 is turned on, and the wind enters the connected telescopic hose 63 from the air outlet end of the fan 64, and then the wind is sent into the connected hard tube 65 from the other end of the telescopic hose 63. The bottom of the hard tube 65 is connected with a thin tube 66, and the thin tubes 66 are evenly arranged side by side. The wind is blown out from the thin tube 66. The hard tube 65 is fixedly installed on the linear motor 62. By adjusting the linear motor 62 to move left and right, the blowing area can be changed, thereby easily solving the problem that the rubber powder will pierce into the mesh holes like fibers and block the mesh holes.

[0028] In summary: the multifunctional rubber powder grading and screening device, through the coordinated use of the cleaning component 6 and the crushing component 8, solves the problem of needing to open the protective cover to clean the powder blocked inside the discharge box, and then closing the protective cover, and requiring manual regular disassembly and cleaning of the device.
