[0025] Preferably, in this embodiment, the distribution device comprises a distribution shaft 12, a distribution wheel 13 and a driving device, a plurality of distribution shafts 12 are rotatably installed in the screening box 1, the outer wall of each distribution shaft 12 is installed with a distribution wheel 13, and the driving device is installed at one end of the distribution shaft 12 penetrating through the side wall of the screening box 1. When the plastic particles enter the screening box 1 through the feeding frame 5, they will first accumulate on one side or in some specific areas of the screen 2. At this time, the driving device is started and begins to operate, driving the distribution shaft 12 connected thereto to rotate. Each distribution shaft 12 is installed with a distribution wheel 13. With the rotation of the distribution shaft 12, the distribution wheel 13 also begins to rotate. These distribution wheels 13 are located above the screen 2 and are designed to uniformly push the accumulated material to each part of the screen 2. The rotation of the distribution wheel 13 not only helps to disperse the material, but also prevents the material from blocking the holes of the screen 2. By adjusting the speed of the driving device and the design of the distribution wheel 13, it can be ensured that the material is uniformly distributed on the entire surface of the screen 2. In this way, the vibration generated by the vibration motor 3 can more effectively separate particles of different sizes. By uniformly distributing the material, the problem of uneven screening caused by local accumulation of the material is avoided, so that the entire screen 2 area can be effectively utilized, thereby improving the screening efficiency.
[0026] Preferably, in this embodiment, the driving device comprises a driving gear 14, a driven gear 15 and a driving motor 16, two sets of driven gears 15 are engaged and installed at the left and right ends of the driving gear 14, one end of the distribution shaft 12 penetrates through the side wall of the screening box 1 and is connected with the corresponding driving gear 14 and driven gear 15, and the driving motor 16 is installed at the end of the driving gear 14 away from the distribution shaft 12. When the equipment starts to run, the driving motor 16 is started first. The driving motor 16 is the core power source of the entire driving system. It is connected to one end of the driving gear 14. The driving motor 16 drives the driving gear 14 to rotate. Since the driving gear 14 is designed to have two sets of driven gears 15 engaged at its left and right ends, when the driving gear 14 rotates, it will simultaneously drive the driven gears 15 on both sides to rotate. Each set of driven gears 15 is connected to one or more distribution shafts 12. With the rotation of the driving gear 14, the driven gears 15 connected thereto also rotate through the meshing between the gears. In this way, even if only one driving motor 16 is used, it can also achieve the simultaneous driving of multiple distribution shafts 12. With the rotation of the driven gears 15, the distribution shafts 12 directly or indirectly connected thereto also rotate. The distribution wheels 13 installed on the distribution shafts 12 move due to the rotation of the distribution shafts 12, and uniformly distribute the material on the screen 2. The design of using one driving motor 16 to drive multiple distribution shafts 12 through a gear train reduces the number of motors required, simplifies the overall mechanical structure, and reduces costs and maintenance difficulty.
[0027] Preferably, in this embodiment, the outer walls of the driving gear 14 and the driven gear 15 are installed with protective shells 17, the gears rotate at high speed during operation, there is a risk of causing harm to the operators, the protective shells 17 can effectively prevent the human body from directly contacting the rotating gears, reduce the possibility of accidental injury, the protective shells 17 can prevent dust, debris and other external impurities from entering the inside of the gear system, avoid the jamming or wear problems caused by these foreign matters, and ensure the stability and reliability of the gear transmission system.
[0028] Preferably, in this embodiment, the driving motor 16 is a servo motor, which can provide very accurate position, speed and torque control, which means that the rotation angle, speed and acceleration of the distribution shaft 12 can be accurately controlled through programming, ensuring that the materials are evenly and accurately distributed on the screen 2.
[0029] Preferably, in this embodiment, two groups of guide plates 18 are symmetrically and obliquely installed in the feeding frame 5, the oblique design of the guide plates 18 helps to guide the materials entering the screening box 1 to flow in a specific direction, which can make the materials reach the surface of the screen 2 in the best speed and distribution manner, thus not only reducing the possibility of material blockage, but also improving the overall efficiency of the screening process.
[0030] Preferably, in this embodiment, the inclination angle of the guide plate 18 is between 30° and 60°, within this angle range, the guide plate 18 can effectively guide the materials to enter the screen 2 at an appropriate flow rate and flow direction, if the angle is too small (less than 30°), the materials may be accumulated or flow slowly, and if the angle is too large (greater than 60°), it may cause the materials to flow too fast, affecting the screening effect, the angle range of 30° to 60° helps to find a balance point to ensure that the materials are evenly and smoothly distributed on the screen 2.
[0031] Preferably, in this embodiment, the buffer seat 8 is filled with damping material 19, the damping material 19 is rubber, which has good elasticity and damping characteristics, and can effectively absorb and disperse the vibration energy generated during the operation of the equipment, which helps to reduce the vibration transmission to the ground or support structure, thereby protecting the equipment foundation from damage.
