The plastic cup and bowl finished product placement piece 3, connected to the first chain 23 and the second chain 24, rotates on the support 1 along with the first chain 23 and the second chain 24. When the vacuum forming machine processes and produces finished cups and bowls, the robot arm of the vacuum forming machine uses negative pressure to adsorb the finished cups and bowls and place them into the placement holes 31 of the plastic cup and bowl finished product placement piece 3. When a certain number of cups and bowls are stacked in each placement hole 31 (for example, 3-5 cups and bowls), the stepper motor is started, which drives the plastic cup and bowl finished product placement piece 3 that has been placed with finished cups and bowls to move downstream, and moves the plastic cup and bowl finished product placement piece 3 that has not yet been placed with finished cups and bowls to the position where the robot arm of the vacuum forming machine places finished cups and bowls. The above process is repeated.

[0043] The process of replacing the finished plastic cup and bowl placement component 3: When installing the finished plastic cup and bowl placement component 3, simply insert the first connector 43 and the second connector into the first slot and the second slot respectively. The first locking connector 41 and the second locking connector are locked by the action of the first reset component 42 and the second reset component respectively. When disassembly is required, pull the first locking connector 41 and the second locking connector respectively to overcome the action of the first reset component 42 and the second reset component, release the locking of the first locking connector 41 and the first connector 43, the second locking connector and the second connector, and directly remove the finished plastic cup and bowl placement component 3 from the first slot and the second slot to complete the installation and disassembly process. Then replace it with a finished plastic cup and bowl placement component 3 of the corresponding specification.
