Description

Technical Field

[0001] The utility model relates to the technical field of sinker processing, in particular to a suction mechanism for sinker processing. Background Art

[0002] After the sinkers are stamped and formed, they will automatically fall onto the conveyor belt conveyor and be transported by the conveyor belt conveyor. During the actual processing, workers need to manually grab the sinkers from the conveyor belt conveyor and place them into the processing lower die one by one. This method requires workers to closely monitor the conveyor belt conveyor at all times, so as to timely take out the sinkers to prevent damage to the sinkers caused by falling. This method will greatly increase the working intensity of workers, and once the workers need to leave the work station, all equipment needs to be shut down, which will greatly affect the processing efficiency. Therefore, it is particularly important to design a suction mechanism for sinker processing to solve the above problems. Summary of the Invention
