Description

Technical Field

[0001] The utility model relates to the technical field of thermos cup production equipment, in particular to a head mechanism and a necking machine with a stripping function. Background Art

[0002] In the field of workpiece processing, such as the processing of thermos cups and thermos pots, shrinking the thermos cup body and thermos pot body is a very common process. Shrinking refers to putting the pre-formed cylindrical or tubular thermos cup body on the rotating main shaft mold, and then pressing the thermos cup body on the rotating main shaft mold through the ram mechanism so that the thermos cup body rotates with the rotating main shaft mold, and finally using a rotatable shrinking roller or shaping disk to press against the outer side of the thermos cup body to shrink the corresponding position of the thermos cup body. In the prior art, the ram mechanism of the shrinking machine can only press down and rotate with the thermos cup body. When the shrinking is completed, the ram mechanism rises. Since the thermos cup body and the ram mechanism are in close contact and connection, the thermos cup body that has completed the shrinking operation is taken out of the rotating main shaft mold, affecting the subsequent processing efficiency. Therefore, a ram mechanism and a shrinking machine with a stripping function are provided to solve the above problems. Utility Model Content
