Molding system for fully degradable biomass agricultural film production

Abstract

The invention belongs to the field of green manufacturing technology, and specifically discloses a forming system for the production of fully degradable biomass agricultural film, including a forming frame and a winding frame. The drug application device on the frame, the side of the drug application device far away from the indentation device is provided with a blanking device fixed on the forming frame, and the side of the blank clamping device away from the drug application device is provided with a winding frame that matches the winding frame. device; the edge-holding device includes an agricultural film holder, and the side of the agricultural film holder away from the pesticide application device is provided with an agricultural film edge holder; the agricultural film holder includes a pair of agricultural film fixing rollers with clearance fit, and any agricultural film is fixed The roller is fixedly connected with the forming frame through the rotating shaft; the agricultural film edge holder includes a main edge roller, and a secondary edge roller matching the main edge roller is arranged under the main edge roller.

Description

technical field [0001] The invention belongs to the technical field of green manufacturing and relates to the technical field of degradable agricultural film production, in particular to a molding system for the production of fully degradable biomass agricultural film. Background technique [0002] my country's mulch film coverage and usage have always ranked first in the world. In the past 30 years, the demand for mulch film has been increasing at an annual rate of about 10%. In 2016, China's annual output of mulch film reached 1.58 million tons, but the original mulch film cannot be degraded Absorption, after use, it needs to be collected and arranged before planting again, which is not only time-consuming and labor-intensive, but also easily causes land pollution. The Nongquan biodegradable mulch film is made of biodegradable plastics, mainly made of renewable resources such as plant cellulose, plant protein and starch. It not only has the functions of ordinary mulch film,...

Problems solved by technology

[0003] Agricultural film is usually used on raised field ridges. Due to its good ductility, ordinary agricultural film does not need to be treated during use. Biomass agricultural film is made of degradable and renewable resources, and its ductility Therefore, when the biomass agricultural film is used on the raised field ridge, when the agricultural film is fixed on both sides of the agricultural film at the same time, it will not only easily cause the agricultural film to break away from the position that needs to be covered, but also easily tear and damage the agricultural film in severe cases. Cause the agricultural film can not be used normally

When the agricultural film is in use, it is necessary to make indentations on the agricultural film to facilitate the germination of the seeds. Farmers generally use finger pressing to make indentations on the agricultural film. The indentation is sunken towards the inner side of the agricultural film, but the seeds germinate and grow into seedlings on the inner side of the agricultural film. When the seedlings are in contact with the indentation, the indentation needs to be pushed back to the original position, and the seedlings can continue to grow and break through the agricultural film before they can grow normally. It can be seen from the growth process of the above-mentioned seedlings that the indentation formed by pressing from the outside of the agricultural film does not reduce the difficulty for the seedlings to break through the agricultural film. The agricultural film cannot be ejected normally, and the seedlings need to be manually cut through the agricultural film, which further increases the planting cost

And after the laying of the agricultural film is completed, due to the suitable temperature and humidity of the soil covered by the agricultural film, the pests and diseases will concentrate activities under the agricultural film, and the seedlings under the agricultural film will die and be seriously damaged.
