Description

Technical Field

[0001] The utility model belongs to the technical field of film processing, and in particular relates to a raw material feeding device for producing porous solvent cast film. Background Art

[0002] Cast film is a non-stretched, non-directional flat extruded film produced by quenching the melt. It has excellent heat-sealing properties and good transparency, and is one of the main composite packaging substrates. During the processing of cast film, it is necessary to load the material into the silo of the processing equipment. The existing loading devices are mostly composed of a loading tank, a feeding pipe, a connecting hose and a negative pressure fan. When in use, the bagged raw materials are first poured into the loading tank by manual handling, and then the negative pressure suction of the negative pressure fan is used in conjunction with the feeding pipe placed inside the feeding tank and the connecting hose between the feeding pipe and the silo of the cast film processing equipment to realize the loading operation of the raw materials. This loading equipment has problems when used in practice. The following are the shortcomings: (1) Since the upper opening of the feeding tank has a certain height, it is more laborious for workers to carry and pour the bagged raw materials, and the raw materials are prone to leakage and spillage; (2) There is no effective limit device between the feed pipe and the feeding tank; (3) Long-term continuous feeding is prone to uneven distribution of raw materials inside the feeding tank, which makes it impossible for workers to accurately observe the amount of raw materials inside the feeding tank, and also affects subsequent feeding operations; Therefore, in order to solve the above problems, it is necessary to develop a raw material feeding device for porous solvent cast film production that is easy to operate and use and has a stable and reasonable structural design.
