Description

Technical Field

[0001] This utility model belongs to the field of table tennis production technology, specifically relating to a table tennis processing carrier circulation mechanism and a table tennis production line including the same. Background Technology

[0002] In the production process of ping-pong balls, two hemispheres need to be made first, namely the male hemisphere and the female hemisphere. Then, the two hemispheres are glued and pressed together. After the glue has cured, the outer glue at the joint of the hemispheres is trimmed.

[0003] Currently, the transfer of ball-carrying carriers in table tennis ball processing mainly relies on robotic arms. These arms place carriers loaded with finished or semi-finished products onto the assembly line. After ball transport is complete, the robotic arms remove the empty carriers from the line and place them to one side. To improve production efficiency, multiple robotic arms and numerous carriers are typically required. The carriers are stacked on one side of the assembly line by the robotic arms, resulting in a large number of carriers and relatively low production efficiency, as the efficiency of individual robotic arms is not improved. To improve the efficiency of carrier transfer and overall processing efficiency in table tennis ball processing, a table tennis ball processing carrier circulation mechanism and a table tennis ball production line incorporating it have been designed to address these problems.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model.
