When the forming and cutting device works, the continuous sheet conveying chain mechanism 2 operates all the time, the forming and cutting mechanism 3 and the continuous sheet conveying chain mechanism 2 synchronously operate in the feeding direction by controlling the driving motor 9, the actions of die assembly, forming, die separation, product cutting and the like are completed in the synchronous operation process of the forming and cutting mechanism and the sheets, and the forming and cutting mechanism 3 quickly returns to the designated original point position of the device to wait for the next cycle process after the actions are completed.
Spatially relative terms, such as "upper," "lower," "left," "right," and the like, may be used in the embodiments for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an upper and a lower orientation. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
Moreover, relational terms such as "first" and "second," and the like, may be used solely to distinguish one element from another element having the same name, without necessarily requiring or implying any actual such relationship or order between such elements.
The invention has been described above by way of example, and it should be noted that any simple variants, modifications or other equivalent substitutions by a person skilled in the art without spending creative effort may fall within the scope of protection of the present invention without departing from the core of the present invention.
