Station changing and unwinding mechanism of material station for belt material processing

Abstract

The invention provides a station changing and unwinding mechanism of a material station for belt material processing. The station changing and unwinding mechanism comprises two vertically-arranged andbilaterally-symmetric vertical station changing devices, wherein unwinding driving heads of the vertical station changing devices are driven by electric cylinder assemblies to vertically move up anddown, can turn over relative to the electric cylinder assemblies, and then can be arranged vertically upward or perpendicular to the electric cylinder assemblies; furthermore, the unwinding driving heads of the two vertical station changing devices are arranged on a common axis, namely a symmetric axis between the two vertical station changing devices; when arranged vertically upward, the unwinding driving heads move up and are used for grabbing belt material trays at a material supply station; when arranged perpendicular to the electric cylinder assemblies, the unwinding driving heads are used for performing the unwinding operation; and the the unwinding driving heads of the two vertical station changing devices act alternately, so that the reel replacement and the unwinding of belt materials can be achieved.

Description

Technical field: [0001] The invention belongs to the technical field of strip-shaped material processing and forming equipment in the tobacco industry, and in particular relates to a transposition unwinding mechanism of a material station for strip-shaped material processing. Background technique: [0002] In the tobacco production process, the use of strip materials is very common, such as cigarette paper, cigarette box lining paper, wrapping paper, etc. in traditional tobacco; PLA material. The strip-shaped material exists in the form of a disc. When using it, it is necessary to install the strip-shaped material disc on the unwinding device, and then pull the head of the strip-shaped material to each roller before starting production. Moreover, generally two Unwinding device, two unwinding devices are used alternately, after one roll of tape-shaped material reel is used up, its tail is spliced ​​with the head of another tape-shaped material reel, and another tape-shaped m...

AI Technical Summary

Problems solved by technology

The planning of the tobacco production workshop at this stage is relatively mature, and it is difficult to find a large area to arrange the material station

[0006] After exploring the existing material stations on the market, it is found that the main reason for their large footprint is that the transposition of the new and old belt-shaped material trays is in the form of a turntable, that is, the new and old belt-shaped material trays alternate positions by doing circular motions, which is impossible Avoid increasing the length of the equipment, resulting in a large material station and a large footprint, which seriously affects the promotion and use of the material station
