Description

Technical Field

[0001] The utility model relates to the technical field of thermos cup welding, in particular to a thermos cup welding machine. Background Art

[0002] Thermos cup is a common container for storing liquid in our daily life. It is mainly composed of an outer shell and an inner liner. The inner liner is generally formed by welding the bottom and the body of the cup. The existing thermos cup welding machine can only perform welding operations on one type of inner liner. For example, Chinese patent CN215091489U discloses a thermos cup bottom and body welding device, which presses the cup body and the bottom of the cup together by pressing the conical pressing part on the cup mouth at the top of the cup body. The motor drives the turntable to rotate. During the rotation of the cup body and the bottom of the cup, the welding gun welds the connection between the cup body and the bottom of the cup. After the cup body and the bottom of the cup are welded, the inner liner is formed;

[0003] However, there are still some shortcomings. The cup bottom enters the cup bottom placement groove through the feed channel, and the welding gun can only weld the cup body and the cup bottom in the welding area at the side end of the inner liner. When the welding area is at the lower end of the inner liner, the cup bottom is placed inside the lower end of the cup body, and the connection between the cup body and the cup bottom is located at the lower end of the inner liner. At this time, this welding device will not be able to perform welding operations, and other equipment needs to be replaced for welding. This requires preparation of multiple equipment for production, which requires more production costs, and also requires a larger site for the placement of equipment. Utility Model Content
