Description

Technical Field

[0001] The present invention relates to the technical field of discharging, and more specifically, to a sieving and discharging structure. Background Art

[0002] During the process of industrial production, a very crucial step is usually involved, which is the feeding of materials. To ensure the smooth progress of the production process and the stability of product quality, the feeding device plays a vital role. The main functions of these devices are to perform preliminary crushing or screening work on various materials. Especially before processing powdery or granular materials, the role of the feeding device is particularly significant. It can evenly disperse these materials in the hopper, thereby effectively preventing the materials from caking during subsequent processing. Caking not only affects the fluidity and uniformity of the materials but may also cause blockage of the equipment, increase maintenance costs, and even affect the quality of the final product. Therefore, through the uniform dispersion of the feeding device, it can ensure that the materials reach the best state before entering the production line, laying a solid foundation for subsequent processing.

[0003] According to the patent document: CN210614339U, a powder coating sieving device disclosed includes a sieving box body, a sieving plate, and a crank rocker sieving mechanism. An inlet is provided at the top of the sieving box body, an outlet is provided at the bottom of the sieving box body, the sieving plate is arranged directly below the inlet, and symmetrically arranged on both sides of the sieving plate are crank rocker sieving mechanisms that drive the sieving plate to swing. The sieving plate is movably arranged in the sieving box body through a rotating shaft in the middle thereof. An inlet funnel is provided at the inlet, and a sealing cover plate is hingedly arranged at the outlet. By arranging crank rocker sieving mechanisms on both sides of the sieving plate, the swinging of the sieving plate is realized, thereby sieving the massive powder. The structure is simple, the cost is low, and it is manually operated, and the sieving process can be controlled at any time, effectively improving the sieving efficiency.

[0004] The general structure of the material screening and processing device is a combination of a hopper and a sieve mesh for preliminary processing of materials. However, when too much or too fast material is added, it is easy to form a bridge on the sieve mesh. If the bridge structure of the material is not destroyed, the material cannot fall under the action of normal weight and will accumulate on the sieve mesh, affecting the sieving and discharging effects. In addition, usually, the material sieve further feeds the material through a connecting pipe. However, when there is a large amount of material in the material sieve, it may cause blockage of the material in the pipe or too slow flow rate of the material in the pipe due to the design of the pipe, thereby affecting the efficiency of the entire screening and discharging process. Summary of the Invention

In addition, usually, the material sieve further discharges the material through a connecting pipe.

[0035] When it is necessary to discharge materials, first pour the materials into the inner sieve tube 21 through the feeding funnel 25 at the top of the inner sieve tube 21. While feeding, start the motor 124. When the motor 124 starts, the left rotating rod 123 drives the elliptical inclined plate 125 to rotate. While the left rotating rod 123 rotates, it drives the second elliptical inclined plate 127 and the second rotating rod 128 to rotate following the rotating rod 123 through the columnar connecting block 126. The rotation of the second rotating rod 128 further drives the second drive shaft 1213 and the gear rotating rod 1221 to rotate through the drive shaft 1210 and the crawler 1212 on the outer wall. The rotation of the gear rotating rod 1221 further drives the gear 1222 at the bottom to rotate. The rotation of the gear 1222 meshes with the internal gear disc 1220 to rotate on the inner wall of the chute disc 1219. The rotation of the chute disc 1219 further meshes with the right gear 1222 to rotate together, so that the rotating rods 123 on both sides and the second rotating rod 128 rotate together. When the two elliptical inclined plates 125, the columnar connecting block 126 and the second elliptical inclined plate 127 rotate, the columnar connecting block 126, through the elliptical hollow design of the push-pull block 1214 and the cooperation with the semi-circular hinge shaft 1216, makes the push-pull block 1214 swing reciprocally on the outer wall of the columnar connecting block 126. The reciprocal swing of the push-pull block 1214 further drives the push-pull connecting rod 1217 and the push-pull rod 1218 to move up and down reciprocally in the inner wall of the auxiliary guide slide tube 122 through the cooperation of the semi-circular hinge shell 1215 and the semi-circular hinge shaft 1216. The up and down reciprocal movement of the push-pull rod 1218 further drives the push-pull disc 23 at the top to shake up and down. When the push-pull disc 23 shakes up and down, through the cooperation of the connecting block 24 on the inner wall of the chute block 112, the spring 113 is compressed and reset. While the push-pull disc 23 shakes up and down, it drives the inner sieve tube 21 to shake up and down in the inner wall of the connecting feeding pipeline 116. The up and down shaking of the inner sieve tube 21 further screens the materials through the sieve mesh. The screened materials fall to the bottom of the inner wall of the connecting feeding pipeline 116, effectively avoiding the problem that when too much or too fast materials are added, it is easy to form a bridge on the sieve mesh. If the bridge structure of the materials is not damaged, the materials cannot fall under the normal weight, and will accumulate on the sieve mesh, affecting the screening and discharging effect. After the materials fall into the inner wall of the connecting feeding pipeline 116, they are discharged through the discharging pipeline 118. At this time, since the rotating rods 123 on both sides and the second rotating rod 128 rotate together, while the second rotating rod 128 rotates, it drives the rotating rods 35 and 36 at the bottom to rotate. While the rotating rod 36 rotates, through the cooperation of the rotating block 37 on the inner wall of the elliptical chute rod 310, the rotating block 37 drives the elliptical chute rod 310 to move back and forth. The back and forth movement of the elliptical chute rod 310 further drives the longitudinal cross connecting rod 313, the discharging pipeline connecting rod 314 and the second discharging pipeline connecting rod 315 to move back and forth in the inner wall of the guide block 32.The connecting rod 314 of the discharge pipe and the second connecting rod 315 of the discharge pipe move back and forth, and then fit on the outer wall of the discharge pipe 118 through the semi-circular cut surface to drive the discharge pipe 118 to vibrate. The vibration of the discharge pipe 118 can shake off the materials adhering to the inner wall of the discharge pipe 118, prevent the materials from being blocked on the inner wall of the discharge pipe 118, and improve the efficiency of material screening and feeding.

[0036] Working principle of the present invention: When it is necessary to discharge materials, first pour the materials into the inner sieve tube 21 through the feeding funnel 25 at the top. While feeding, start the motor 124. When the motor 124 starts, it drives the left-side rotating rod 123 to rotate. While the left-side rotating rod 123 rotates, it drives the elliptical inclined plate 125 to rotate. When the elliptical inclined plate 125 rotates, it drives the second elliptical inclined plate 127 and the second rotating rod 128 to rotate following the rotating rod 123 through the columnar connecting block 126. The rotation of the second rotating rod 128 further drives the second transmission shaft 1213 and the gear rotating rod 1221 to rotate through the transmission shaft 1210 and the crawler 1212 on the outer wall. The rotation of the gear rotating rod 1221 further drives the gear 1222 at the bottom to rotate. The rotation of the gear 1222 meshes with the internal gear disk 1220 to rotate on the inner wall of the chute disk 1219. The rotation of the chute disk 1219 meshes with the right-side gear 1222 to rotate together, so that the rotating rods 123 on both sides and the second rotating rod 128 rotate together. When the two elliptical inclined plates 125, the columnar connecting block 126 and the second elliptical inclined plate 127 rotate, the columnar connecting block 126, through the cooperation of the elliptical hollow design of the push-pull block 1214 and the semi-circular hinge shaft 1216, makes the push-pull block 1214 swing reciprocally on the outer wall of the columnar connecting block 126. The reciprocal swing of the push-pull block 1214 further drives the push-pull connecting rod 1217 and the push-pull rod 1218 to move up and down reciprocally in the inner wall of the auxiliary guide slide tube 122 through the cooperation of the semi-circular hinge shell 1215 and the semi-circular hinge shaft 1216. The up-and-down reciprocal movement of the push-pull rod 1218 further drives the push-pull disk 23 at the top to vibrate up and down. When the push-pull disk 23 vibrates up and down, through the cooperation of the connecting block 24 on the inner wall of the chute block 112, the spring 113 is compressed and reset. While the push-pull disk 23 vibrates up and down, it drives the inner sieve tube 21 to vibrate up and down in the inner wall of the connecting feeding pipe 116. The up-and-down vibration of the inner sieve tube 21 further screens the materials through the sieve mesh. The screened materials fall to the bottom of the inner wall of the connecting feeding pipe 116. After the materials fall into the inner wall of the connecting feeding pipe 116, they are discharged through the discharge pipe 118. At this time, since the rotating rods 123 on both sides and the second rotating rod 128 rotate together, while the second rotating rod 128 rotates, it drives the rotating rods 35 and 36 at the bottom to rotate. While the rotating rod 36 rotates, through the cooperation of the rotating block 37 on the inner wall of the elliptical chute rod 310, the rotating block 37 drives the elliptical chute rod 310 to move back and forth reciprocally. The back-and-forth movement of the elliptical chute rod 310 further drives the longitudinal cross connecting rod 313, the discharge pipe connecting rod 314 and the second discharge pipe connecting rod 315 to move back and forth in the inner wall of the guide block 32 through the push-pull cross bar 39. The back-and-forth movement of the discharge pipe connecting rod 314 and the second discharge pipe connecting rod 315 further drives the discharge pipe 118 to vibrate through the semi-circular section fitting on the outer wall of the discharge pipe 118. The vibration of the discharge pipe 118 can shake off the materials attached to the inner wall of the discharge pipe 118.
