Abstract

The invention relates to a device for utilizing a net laying-papermaking combined method to prepare environment-friendly type bast fiber mulch films and a use method thereof. The device comprises a feeding machine (1), an air flow net forming machine (2), a screen (14), a transmission mechanism (15), an air suction device (3), a pulping device (4), a suction filtration device (5), a compression roller (6), a spraying machine (7), an air extracting device (8), a drying device (9), a coating device (10), a glazing calender (11), an edge trimming machine (12) and a coiling machine (13). Accordingto the device disclosed by the invention, a complete bast fiber mulch film preparation production line is assembled, so that the problems of batch production and stable production of the bast fiber mulch films are solved; the environment-friendly type bast fiber mulch films which has the advantages of stable quality, even structure, high strength and low cost can be prepared out; stable production of the bast fiber mulch films is achieved; reagents for preventing insects, inhibiting grass and the like can be added into a spraying device according to needs; thus, the bast fiber mulch films fordifferent purposes can be produced out.

Description

technical field [0001] The invention belongs to the field of a device for preparing a mulch film and a method for using it, and in particular relates to a device for preparing an environment-friendly hemp mulch film by a combined method of net laying and papermaking and a method for using the same. Background technique [0002] Plastic mulch is widely used in modern agriculture. It has the functions of promoting crop growth, increasing yield, keeping warm and moisturizing, and preventing insects. However, plastic mulch is difficult to degrade, and if left in the farmland, it will cause damage to the soil structure and affect the growth and development of crops. Therefore, developing low-cost, naturally degradable mulch films is an important way to reduce environmental pollution. [0003] The invention patent with the publication number CN101215786 "Preparation device for environmentally friendly hemp mulch film" includes an opener, a mechanical cross-lapper, an air-laid mach...
