Detailed Description

The present utility model will be described more fully with reference to the following examples. This utility model may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein.

Spatially relative terms, such as "upper," "lower," "left," "right," and the like, may be used herein for ease of description to describe one element or feature's relationship to another element or feature's 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 "under" other elements or features would then be oriented "over" the other elements or features. Thus, the exemplary term "lower" may encompass both an upper and lower orientation. The device may be otherwise positioned (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

As shown in fig. 1, the infusion bag packaging film manufacturing device in the embodiment comprises a heating module 1, an upper die 2, a lower die 5 and a lower die lifting mechanism 4; the lower die is the infusion bag packaging film manufacturing die. The lower die lifting mechanism 4 can adopt an air cylinder 6 as driving power; the upper die 2 and the lower die 5 can be aligned by adopting a sliding block and a guide rail; the sliding block and the guide rail can be connected by adopting a positioning guide bearing.

The heating module 1 is used for heating the upper die 2; it is also necessary to evacuate the mold by means of a vacuum generator. The heating module 1 and the vacuum generator are both of the prior art, and are not described in detail here.

As shown in fig. 2 and 3, the lower die 5 is composed of a die holder and a plurality of sub-dies 52; the mold support is provided with a plurality of sub-mold accommodating grooves 51, and the sub-mold 52 is placed in the sub-mold accommodating grooves 51. When different infusion bags are packed, only the submodules with corresponding models are needed to be replaced.
