Today, I introduce the structural principle of shrink tunnel machine. Automatic shrink tunnel machine is also known as the piping cutting machine, it as a fully automatic can be unmanned operation of the film cutting and packaging machine, is the current people often used thermal shrinkage packaging equipment, is widely used in beverage food, tea, local specialties, drinks, candy, biscuits, and even medicine and other industries. With the existence of shrink tunnel machine, the product can be automatically detected by photoelectric, and then realize the automatic unmanned packaging process, so that the efficiency of packaging has been improved, can be adjusted to various sizes of packaging, but also can be adjusted to different types and shapes of products. The working principle of shrink tunnel machine is relatively simple, usually adopts folding mold as the packaging material, and then uses the triangle plate shaper to relatively elaborate fully open, when the conveyor belt of packaging works, the puller will also work synchronically, so that the packaged object is packed in the sandwich of folding film. When the film puller is working, the side of the folded film will be fully pressed and stitched, and the transverse cutting knife will work once for each item packed, and then the whole closed packaging work will be completed. Then enter the heat shrink packaging machine to complete the overall heat shrink packaging work, Although the design principle of the shrink tunnel machine is simple, but according to the different price, the shrink tunnel machine is often divided into different types, such as economic shrink tunnel machine, high-speed shrink tunnel machine and double shrink tunnel machine. At present, the packaging materials for the shrink tunnel machine are more and more common, such as polyethylene, polyvinyl chloride, polypropylene, environmental protection film and so on. The shrink tunnel machine is combined with a single machine to form a H-type four-corner sealing series, and then online matching, and then combined into (I-type automatic sealing) operation. The shrink tunnel machine adopts transmission design, and its upper and lower transmission boxes are sealed and packed. This manual adjustment type is suitable for the same carton with standardized packing order at the same time, while the self-adjustment type is suitable for carton sealing with a variety of specifications. The conversion specifications can be completed by self-adjusting (shrinkage tunnel machine can be adjusted in real time according to the specifications of the carton) or manually adjusting.
