At the same time, the raw materials need to be screened before use, and raw material powder particles with suitable particle size are selected for production operations to obtain excellent preparation and production effects. However, in the prior art, screening on ordinary screening plates is prone to accumulation, and the screen holes of the screening plates are easily blocked, which reduces the screening efficiency, resulting in low screening efficiency and poor effect. The use of vibrating screen separation causes large vibration and noise during the vibration separation process, and the vibration over a long period of use will affect the overall structure of the screening device and reduce its service life. In view of this, we provide a screening device for processing wire and cable raw materials to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] See also Figure 1-5 The utility model provides the following technical solutions: a screening device for processing raw materials of wires and cables, comprising a screening box 1 and a material storage tray 2, the screening box 1 and the material storage tray 2 are distributed up and down, and a supporting leg 3 is installed between the screening box 1 and the material storage tray 2, a feeding hopper 4 is installed at the top of the screening box 1, a discharging hopper 5 is installed at the bottom of the screening box 1, an electromagnetic control valve 6 is installed on the surface of the discharging hopper 5, a screening plate 7 is arranged in an inclined shape inside the screening box 1, two corresponding connecting blocks 8 are installed on the side wall inside the screening box 1, a connecting rod 9 is installed between the two connecting blocks 8, two corresponding supporting blocks 10 are installed on the side wall of the screening box 1 away from the connecting block 8, a motor 11 is installed on the outer side wall of the screening box 1 close to the supporting block 10, an eccentric wheel 12 is installed on the output shaft of the motor 11, and a guide plate 17 is installed inside the screening box 1 and at the bottom end of the screening plate 7.

[0023] Preferably, the connecting rod 9 passes through one end of the screening plate 7 , and the screening plate 7 is rotatably connected to the surface of the connecting rod 9 , and the other end of the screening plate 7 is overlapped on the top of the supporting block 10 .

[0024] Preferably, the eccentric wheel 12 is rotationally connected to the screening box 1 through the motor 11 , and the screening plate 7 is movably connected to the screening box 1 through the eccentric wheel 12 .

[0025] In the embodiment, when the raw materials of wires and cables are screened, the raw materials are fed from the feed hopper 4, and then the raw materials enter the screening box 1 from the feed hopper 4, and then the motor 11 is started to drive the eccentric wheel 12 to rotate. During the rotation of the eccentric wheel 12, one end of the screening plate 7 will move up and down, and the other end of the screening plate 7 will move along the surface of the connecting rod 9. With the movement of the screening plate 7, the raw materials will be screened. At the same time, during the rotation of the eccentric wheel 12, one end of the screening plate 7 will also collide with the support block 10 to form vibration, thereby shaking off the raw materials blocked in the sieve holes, avoiding the situation where the raw materials block the sieve holes, thereby increasing the screening efficiency, and at the same time reducing the vibration efficiency of the screening plate 7, and improving the service life. Then, the raw materials screened by the screening plate 7 fall into the guide plate 17, and then flow to the discharge hopper 5 along the guide plate 17, and then open the electromagnetic control valve 6 to allow the raw materials to flow from the discharge hopper 5 to the storage tray 2 for storage.

[0030] In the embodiment, according to the description of the first embodiment, when the raw materials enter the material storage tray 2, they will fall into the discharge trough 13, and then the discharge port 14 will be opened when taking the materials, so that the raw materials can flow from the discharge port 14 to the outside for storage, and at the same time, the motor 15 may be started to drive the output shaft of the motor 15 to drive the paddle 16 to move in a circle along the discharge trough 13, thereby moving the raw materials inside the discharge trough 13 close to the discharge port 14, so that the raw materials can flow out from the discharge port 14 to the outside, thereby increasing the convenience of discharging.

[0031] In summary, according to the description of embodiments one and two, when the screening device is working, not only the blockage is reduced, but also the vibration frequency is reduced, so that the screening efficiency and service life of the screening device are improved.
