Silk-unfolding, gluing and laminating device system based on no-woven cloth production

Abstract

The invention discloses a silk-unfolding, gluing and laminating device system based on no-woven cloth production. The silk-unfolding, gluing and laminating device system comprises a machine frame, silk-unfolding units fixed to the machine frame for unfolding silk flocks into sheets and a gluing unit. The silk-unfolding units comprise a plurality of silk-unfolding rollers arranged in sequence, andthe silk-unfolding rollers are composed of curved straight surface silk-unfolding rollers, electrostatic silk-unfolding rollers, a large cylindrical silk-unfolding roller and a small cylindrical silk-unfolding roller. The gluing unit comprises a glue dipping roller, a glue pressing roller pair of which pressure and ground clearance of the axes are adjustable, a glue tank, trays, a scaleplate and lifting structures for controlling the height of the glue tank. The glue dipping roller is disposed directly above the glue tank, and the trays are fixed to both ends of a glue tank body. The scaleplate is disposed on the lifting structures, and the lifting structures are lifting devices with hand-cranking arms and are fixed to the machine frame. According to the overall technical scheme, the silk-unfolding, gluing and laminating device system is simple and compact in structure, ingenious and reasonable in connection between the components, easy to install and adjust, low in cost, and conduciveto the market promotion and the use of middle and small-sized enterprises.

Description

technical field [0001] The invention relates to the technical field of non-weft fabric production, in particular to a system based on a spinning, gluing, and film-coating device for non-weft fabric production. Background technique [0002] High-performance fiber "UD" non-weft fabric is based on high-performance fiber, such as ultra-high molecular weight polyethylene fiber and aramid fiber. combined, and then formed by orthogonal composite lamination. It has excellent properties such as soft hand feeling, low density, abrasion resistance, impact resistance, and strong cutting toughness. It is the bulletproof material with the highest strength and the lightest specific gravity in the world today. In the prior art, the following methods are basically used in the production of non-webbing: the tow drawn from the silk drum is evenly expanded into a uniform sheet, glued into a unidirectional sheet, dried, rolled and formed, and then Subsequent work continues to produce web-free...

Problems solved by technology

[0003] Chinese patent CN106467983A discloses a kind of stretching equipment of ultra-high molecular weight polyethylene fiber, but it only uses curved surface and corners to spread the spinning effect is not good; Chinese patent CN102433767B discloses a production line for preparing polyethylene fiber unidirectional prepreg tape, It uses a high-voltage electrostatic device to spread the filaments, but this method increases the risk of production, which is not conducive to the production and large-scale promotion of enterprises; Chinese patent CN107475945A discloses a new type of sizing and shaping system and sizing process for carbon fibers. The structure of the equipment is relatively complicated, and the speed of gluing is difficult to increase

In view of the existing technology in the production process, there are the following problems: 1. After the gluing speed of the machine is increased, the coating effect of the stretched yarn is reduced, and it is prone to wrinkles and breaks, which cannot guarantee the high-speed gluing state. Flat and constant film; 2. The overall structure design is complicated, and the high cost is not conducive to the promotion of the market and the application of small and medium-sized enterprises; 3. After the machine stops running, the glue solidifies and pollutes the roller surface; 4. Behind the rubber roller The rollers are fixed installation, the space is narrow and it is inconvenient to clean, which affects the quality of the product
