[0020] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0021] like Figure 1-4 As shown, a raw material screening device for zirconium silicate ceramic processing includes a bracket 101, a support plate 102 and a screen 103. The support plate 102 is fixedly connected to one side of the bracket 101, and the screen 103 is arranged on the inner side of the bracket 101. The support plate 102 is provided with a screening mechanism and an adjustment mechanism; the screening mechanism includes a servo motor 201, a rotating rod 202, an output wheel 203, a rotating column 204, a pulley 205, a transmission belt 206, a turntable 207 and a connecting rod 208. The servo motor 201 is fixedly installed on the top of the support plate 102. One end of the rotating rod 202 is fixedly connected to the output end at the bottom of the servo motor 201, the other end of the rotating rod 202 passes through the top of the support plate 102, the output wheel 203 is sleeved on the surface of the rotating rod 202, the rotating column 204 is connected to the inside of the support plate 102 through a bearing, the top of the rotating column 204 passes through the top of the support plate 102, the other end of the rotating column 204 passes through the bottom of the support plate 102, the pulley 205 is sleeved on the surface of the rotating column 204, and the transmission belt 206 is respectively sleeved on the pulley 205 and the output wheel 20 3, the turntable 207 is fixedly connected to the top of the rotating column 204, one end of the connecting rod 208 is connected to one side of the screen 103 through a hinge, and the other end of the connecting rod 208 is connected to the adjustment mechanism; the adjustment mechanism includes an adjustment frame 209, a slide 210, a threaded rod 211 and a sliding block 212, the adjustment frame 209 is fixedly connected to the top of the turntable 207, the slide 210 is opened at the top of the adjustment frame 209, one end of the threaded rod 211 is connected to the inner wall of the slide 210 through a bearing, and the other end of the threaded rod 211 is connected to the inner wall of the slide 210 through a bearing. It passes through one side of the adjustment frame 209, and the sliding block 212 is threadedly connected to the surface of the threaded rod 211. The sliding block 212 is slidably connected to the inside of the slide groove 210. The connecting rod 208 is connected to the top of the sliding block 212 through a rotating shaft. Through the mutual cooperation of the screening mechanism and the adjustment mechanism, the eccentric distance of the output point of the screening device can be adjusted, and the vibration amplitude of the screening device can be flexibly adjusted according to the characteristics of the raw materials to avoid the raw materials from clogging the screen 103, so that the equipment can adapt to the screening needs of various raw materials and improve the flexibility and adaptability of production.

[0022] like Figure 4As shown, transverse grooves 301 are provided on both sides of the bracket 101, and sliding rods 302 are fixedly connected on both sides of the screen 103. The sliding rods 302 are slidably connected to the inside of the transverse grooves 301. When the screen 103 is shaking, the screen 103 will drive the sliding rods 302 to move parallel to the inside of the transverse grooves 301. With the cooperation of the sliding rods 302 and the transverse grooves 301, the screen 103 can be shaken in parallel. The parallel shaking makes the surface of the screen 103 evenly stressed, and the raw materials can be distributed more smoothly on the screen 103, increasing the contact area between the raw materials and the screen 103, thereby improving the screening efficiency.

[0023] like Figure 4 As shown, the inner wall of the transverse groove 301 is fixedly connected with a round rod 303, and the sliding rod 302 is slidably connected to the surface of the round rod 303. A compression spring 304 is arranged inside the transverse groove 301, one end of the compression spring 304 is fixedly connected to the inner wall of the transverse groove 301, and the other end of the compression spring 304 is fixedly connected to the surface of the sliding rod 302. When the sliding rod 302 slides inside the transverse groove 301, the sliding rod 302 can squeeze the compression spring 304, and then under the rebound force of the compression spring 304, the shaking amplitude of the screen 103 can be increased, thereby improving the screening efficiency of the raw materials, and with the auxiliary limitation of the round rod 303, the sliding rod 302 can be limited inside the transverse groove 301 to prevent the sliding rod 302 from tilting inside the transverse groove 301 or detaching from the inside of the transverse groove 301 when sliding.

[0024] like Figure 1 As shown, the top of the screen 103 is fixedly connected with auxiliary teeth 4, and the teeth at the bottom of the auxiliary teeth 4 are adjacent to the holes of the screen 103. The auxiliary teeth 4 increase the contact area between the raw material and the screen 103, so that the raw material has more opportunities to contact the screen holes when passing through the screen 103, thereby improving the screening effect, and for wet or sticky raw materials, the auxiliary teeth 4 can effectively prevent the raw materials from adhering.

[0025] like Figure 1 and Figure 4 As shown, a receiving plate 501 is connected to the inner side of the bracket 101, and the inner wall of the receiving plate 501 is bucket-shaped. A discharge chute 502 is provided at the bottom of the receiving plate 501, and the bottom hinge of the discharge chute 502 is connected to the bottom plate 503, and the bottom plate 503 is connected to the threaded hole at the bottom of the receiving plate 501 through a screw. After the raw materials are screened, the raw materials will automatically fall into the receiving plate 501, and the screened raw materials will be collected to ensure that the raw materials can be smoothly and effectively introduced into subsequent processing or storage equipment. Under the bucket-shaped receiving plate 501, the raw materials can be prevented from accumulating on the receiving plate 501, and the fluidity of the raw materials can be maintained. Finally, the screw is turned downward to disengage the screw from the threaded hole on the receiving plate 501, which is convenient for the staff to open the bottom plate 503 and discharge the raw materials in the receiving plate 501 from the discharge chute 502.

[0026] The working principle of the present invention is as follows: when screening raw materials, the raw materials can be poured onto the screen 103 first, and then the servo motor 201 is operated. The operation of the servo motor 201 will drive the rotating rod 202 to rotate, and the rotation of the rotating rod 202 will drive the output wheel 203 to rotate. The rotation of the output wheel 203 will drive the pulley 205 to rotate through the transmission belt 206. The rotation of the pulley 205 can simultaneously drive the rotating column 204 and the turntable 207 to rotate. The rotation of the turntable 207 can drive the adjusting mechanism at the top to rotate at the same time. The rotation of the adjusting mechanism can also drive one end of the connecting rod 208 to rotate around the rotation trajectory of the turntable 207, and then the screen 103 is driven to swing back and forth on the inner side of the bracket 101 through the connecting rod 208, so that the raw materials on the screen 103 are The materials are screened. When screening some raw materials with higher humidity, the staff can rotate the threaded rod 211. The rotation of the threaded rod 211 can drive the threaded sliding block 212 to slide inside the slide 210. When the sliding block 212 moves away from the center distance of the turntable 207, it can drive the connecting rod 208 to move. Therefore, the eccentric distance between the output end of the screening device and the turntable 207 can be adjusted by the adjustment mechanism. When the eccentric distance is larger, the centrifugal force generated by the turntable 207 during rotation is also larger, which will cause the turntable 207 to drive the connecting rod 208 and the screen 103 to shake more, thereby ensuring that the raw materials with higher humidity can effectively pass through the screen 103, which helps to prevent the screen holes from being blocked, ensure the smooth operation of the equipment, and improve the screening efficiency.
