Adjustable lifting cloth storage rack

Abstract

The invention discloses an adjustable lifting cloth storage rack, which comprises a cloth storage rack upper frame, a cloth storage rack lower frame, a telescopic cylinder and sliding rods. Four corners of the cloth storage rack upper frame and four corners of the cloth storage rack lower frame are provided with supports; the sliding rods are vertically arranged on the supports and support the cloth storage rack upper frame and the cloth storage rack lower frame; upper guide roller groups are parallelly arranged on the cloth storage rack upper frame; lower guide roller groups are parallelly arranged on the cloth storage rack lower frame; and the adjustable lifting cloth storage rack is provided with an adjusting mechanism which comprises a driving steel roller, a driving device in drive connection with the driving steel roller, and a pinch rubber roller matched with the driving steel roller; the lower parts of the lower guide roller groups of the cloth storage rack lower frame are provided with at least two guide rollers; the lower part of the cloth storage rack upper frame is provided with a connecting piece; and the cloth storage rack lower frame is detachably connected with theconnecting piece. Therefore, the positions of the cloth storage rack upper frame and the cloth storage rack lower frame can be adjusted, so that thin films are stressed uniformly and extended flatly.

Description

Technical field [0001] The present invention involves a kind of storage rack, especially a thin film that is suitable for thin, thin, or air -containing thin -film racks. Background technique [0002] In the existing technology, the "forming -filling -seal — Seal, referred to as FFS) bags for continuous production of" formation -filling -filling -fem — FFS) is an important packaging film technology developed in recent years., It is mainly used for automatic packaging lines for synthetic resin products such as large polyethylene and polypropylene.During the packaging operation, the multi -process and operation processes are completed and automatically completed, so that the packaging capacity can usually reach 1700-1900 bags / h, thereby meeting the needs of high -speed packaging of ultra -large synthetic resin devices. [0003] All procedures for printing production processes specifically for FFS packaging bags are continuously operated. However, when new film rolls need to be repl...

Problems solved by technology

[0005] However, the cloth storage racks usually used for printing in the prior art are all fixed-length fixed cloth storage racks. Although this kind of fixed cloth storage rack has a large amount of film storage and a long film storage section, it cannot adapt to multiple Films of various specifications, especially films with soft, thin or air-containing properties, and in long-term continuous operation, it is easy to cause problems such as buckling deformation and wrinkles of the film, and more seriously, it will affect The normal operation of the entire printing production
