[0002] Zinc ingots are generally cast using a straight-line ingot casting machine. After the zinc ingots cast by the straight-line ingot casting machine are demolded, they are introduced into a dropping ingot variable-speed conveying roller path by a ingot receiving device. The zinc ingots then pass through the conveying roller path, the zinc ingot water-cooling conveying device, the ingot turning mechanism, and the chute in sequence. Finally, they are pushed into the zinc ingot grasping station by a ingot pushing device, shaped by a cylinder, and then grasped by an automatic robot and transported to a zinc ingot stack conveyor for stacking. After stacking is completed, they are transported to a bundling station, and after bundling is completed, they are transported to a waiting-for-lifting station. Currently, during the operation of the ingot turning mechanism, it is not convenient to control the action frequency of the electric push rod, resulting in inconvenience in adjusting the number of zinc ingots entering the turning plate, thus affecting the accurate reversing and normal conveying of the bottom ingots of the ingot stack.

[0015] In this embodiment: The two chains 2 are respectively installed on the two brackets 1, and the multiple zinc ingots 3 are conveyed through the chains 2.

[0016] The working principle and usage process of the present utility model:

[0017] 1. After the zinc ingots 3 are cooled by the cooling system, they are conveyed to the stacking line through the chains 2;

[0018] 2. When the chains 2 convey the zinc ingots 3 past the counter 6, the two counting modules start counting;

[0019] 3. When the first zinc ingot 3 appears at the counter 6, a signal is transmitted to the electric push rod 405, the servo motor 403, and the push rod motor 406, and the push rod motor 406 drives the electric push rod 405 to retract;

[0020] 4. The electric push rod 405 retracts, controlling the lowering of the flipping frame 401;

[0021] 5. The lowering of the flipping frame 401 causes the flipping plate 402 to contact the zinc ingot 3. As the chain 2 moves, the zinc ingot 3 is conveyed into the flipping plate 402;

[0022] 6. The servo motor 403 drives the flipping plate 402 together with the zinc ingot 3 to complete a 180° rotation for direction change;

[0023] 7. The counter 6 accumulates the count, and repeats step 6 to complete the direction change of the zinc ingot 3 (with the grooved side facing downwards) 6 times;

[0024] 8. When the zinc ingot 3 whose direction has been changed in step 7 passes through the sensor 5, signals are simultaneously transmitted to the servo motor 403 and the palletizer. The servo motor 403 prepares for the next action, and automatic palletizing realizes linkage control for automatic palletizing of zinc ingots;

[0025] 9. When the counter 6 accumulates the count to the 7th zinc ingot, signals are transmitted to the electric push rod 405, the servo motor 403, and the push rod motor 406. The servo motor 403 stops operating, and the push rod motor 406 drives the electric push rod 405 to extend;

[0026] 10. The electric push rod 405 extends to lift the flipping plate 402, and the zinc ingot 3 is normally conveyed by the chain 2 (with the grooved side facing upwards) without direction change;

[0027] 11. Repeat step 10 until the counter 6 accumulates the number of zinc ingots to 46 pieces, completing one stack;

[0028] 12. The counter 6 is cleared and starts counting again;

[0029] 13. Repeat the above actions to start the direction change action of the next stack of zinc ingots.

[0030] The above has introduced in detail the technical solutions provided by the embodiments of the present invention. Specific examples are used herein to elaborate on the principles and implementation manners of the embodiments of the present invention. The descriptions of the above embodiments are only applicable to helping understand the principles of the embodiments of the present invention. At the same time, for those of ordinary skill in the art, based on the embodiments of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
