The feeding motor drives the screw rod to rotate through the pulley and belt. The screw rod pushes the bead cores into the inside of the feeding tube. The bead cores are fed in intermittently. The output end of the polishing and forward and reverse motor drives the driving shaft to rotate, so that the large sprocket and the small sprocket drive the sprocket to rotate through the chain, so that the rotating cylinder, the polishing cylinder and the polishing strip rotate together, and the bead core is polished by the polishing cylinder and the polishing strip; The output end of the material turning and electric push rod cyclically extends and retracts, so that the connecting plate drives the material turning rod to insert and pull out inside the material turning hole. When inserting, the bead core is pushed upward for a short distance, and when pulling out, the bead core falls under the action of its own gravity, so that the bead core rolls during the movement; The discharging and feeding mechanism feeds the materials, and the polished beads enter the discharging pipe and are discharged in sequence; Sandblasting and polishing, the air pump fills the air into the air inlet pipe through the air guide pipe. Under the action of the airflow, the fine sand inside the sand inlet pipe is mixed into the gas. The airflow passes through the gap between the outer wall of the bead core and the polishing cylinder, so that the fine sand polishes the outer wall of the bead core; Sand discharge, fine sand after polishing and polishing debris are discharged from the sand discharge hole. Beneficial Effects

[0013] When polishing the bead core, the bead core is fed into the multi-stage polishing mechanism through the feeding assembly for multi-stage polishing. At the same time, the driving mechanism provides power for the multi-stage polishing mechanism. The polished bead core is sequentially discharged through the multi-stage polishing mechanism.

[0014] During polishing, the feed pipe is provided to facilitate continuous feeding, the discharge pipe is provided to facilitate discharge, and a plurality of polishing mechanisms are stacked to allow the beads entering the multi-stage polishing mechanism to be polished to achieve multi-stage polishing.

[0015] During polishing, the rotating cylinder rotates, causing the polishing cylinder and a number of polishing strips to rotate together, so that the bead core located inside the polishing cylinder is polished by the polishing cylinder and a number of polishing strips, wherein the adjacent rotating cylinders can be rotatably connected through the arrangement of arc grooves, rollers, connecting rings and connecting grooves, and double polishing is performed by fine sand and the polishing cylinder. Under the action of airflow, the polishing debris polished out can be quickly discharged downward, and the presence of airflow can cool the outer wall of the bead core, so that the bead core can reduce the problem of over-polishing caused by thermal expansion.

[0016] When driving, the output end of the forward and reverse motor drives the driving shaft to rotate, so that the large sprocket and the small sprocket on the driving shaft drive the sprocket to rotate through the chain, so that the rotating cylinder rotates. By alternating the large sprocket and the small sprocket, a speed difference can be generated between adjacent rotating cylinders. When the bead core moves inside the polishing cylinder, the bead core is subjected to different forces, causing the bead core to roll; and when polishing, the debris generated by polishing can be added to the polishing process of the lower layer, thereby improving the polishing quality of the lower polishing mechanism.

[0017] By setting different polishing meshes, when the bead core enters the polishing mechanism for polishing, multi-level polishing can be performed, so that the lower polishing mechanism performs rough polishing and the top polishing mechanism performs fine polishing, so that the polishing of the bead core can be performed step by step.

[0018] The polishing cylinder and the polishing strip are both made of cotton mixed with abrasive sand, so that the inner wall of the polishing cylinder and the outer wall of the polishing strip are covered with abrasive sand, and the polishing cylinder and the polishing strip are flexible. When the bead core passes through the inside of the polishing cylinder, the polishing cylinder rotates at high speed, and the inside of the bead core polishing cylinder reciprocates. The contact surface between the inner wall of the polishing cylinder and the outer wall of the polishing strip and the bead core polishes the outer wall of the bead core, and the bead core flips inside the polishing cylinder.

[0019] When the bead nucleus is flipped, the output end of the electric push rod cyclically extends and retracts, causing the connecting plate to cyclically move up and down, and the flipping rod to cyclically insert and pull out the inside of the flipping hole. When inserting, the top of the flipping rod pushes the bead nucleus to move upward. When pulling out, the bead nucleus moves downward under the action of its own gravity. During the movement of the bead nucleus, the bead nucleus is flipped, making the polishing of the outer wall of the bead nucleus more even.

[0020] Compared with the prior art, the present invention provides a feeding mechanism and a multi-stage polishing mechanism so that the bead cores can enter sequentially during polishing, and after completing the multi-stage polishing, they can be discharged sequentially for convenience of subsequent processes. The polishing cylinder and the polishing strip are provided so that when the polishing cylinder rotates, it drives the polishing strip to polish the bead core. At the same time, the large sprocket and the small sprocket are alternately provided so that the rotation speeds of adjacent polishing cylinders are different, so that the bead cores passing through the interiors of two adjacent polishing cylinders are turned over due to uneven force, thereby improving the polishing quality of the bead core. At the same time, the turning rod and the turning hole are provided so that the turning hole can discharge the debris generated by polishing and the bead core can be moved up and down by the insertion and withdrawal of the turning rod, thereby improving the polishing quality. The airflow can reduce the temperature of the outer wall of the bead core, thereby reducing the problem of over-polishing of the bead core due to thermal expansion.
