Many traditional mechanical production methods have been integrated with automation technology to achieve high industry returns, for example, in the field of automated production and processing of thermos cups.

[0003] In the process of automatic production of thermos cups, it is an essential process to squeeze and shrink the mouth of the thermos cup blank. The shrinking process refers to a forming process in which the end of the thermos cup blank is reduced by a shrinking die. The conventional shrinking process of the thermos cup is to grab the thermos cup blank by a six-axis or four-axis manipulator, place the thermos cup blank on a rotatable shrinking die, and then press the cup blank with a cup blank fixing mechanism, and use the shrinking roller to extrude the mouth of the thermos cup blank placed on the rotatable shrinking die.

After the necking is completed, the first servo motor of the second transfer mechanism 12 rotates, and the active synchronous pulley, the rotating shaft and the connecting piece follow the rotation movement. The active synchronous pulley drives the driven synchronous pulley and the fixed shaft to rotate to the specified position through the first synchronous belt. The specified position is above the object with the necking completed. The clamping mechanism clamps the object with the necking completed, and then moves through the second transfer mechanism 12 to move the object with the necking completed to the next workstation.

The two transplanting mechanisms of the equipment itself can replace two traditional robot transplanting devices. One of the two transplanting mechanisms is responsible for taking the cup blanks, and the other is responsible for placing the cup blanks.

The production cycle is shortened and the production efficiency is optimized. At the same time, the shrinking process that originally required the use of two robot transplanting devices to complete is optimized to be completed using one device, thereby reducing production costs.
