Biological-based degradable cotton planting mulching film mechanism and preparation method

Abstract

The invention discloses a biological-based degradable cotton planting mulching film mechanism and a preparation method. The mechanism is characterized by comprising raw materials, a high-speed mixingmachine, a separation detection machine, a granulator and a film blowing machine, wherein the raw materials is prepared from 5 to 25% of polylactic acid, 43 to 48% of poly terephthalic acid-butanedioic acid-butylene glycol ester and the like; a weighing material barrel comprises a support, a barrel body and the like, a U-shaped rod is arranged in the barrel body, a hair brush is arranged on the U-shaped rod, the bottom surface of the U-shaped rod is connected with one end of a rotary handle, the other end of the rotary handle is arranged on the outer side of the barrel body, a bearing is arranged on the outer side of the bottom surface of the barrel body, and the rotary handle penetrates through the bearing. According to the biological-based degradable cotton planting mulching film mechanism disclosed by the technical scheme of the invention, the hair brush is arranged in the weighing material barrel; when the raw materials in the weighing material barrel are poured into the high-speedmixing machine, the rotary handle is rotated to make the hair brush sweep raw material powder on an inner wall of the weighing material barrel into the high-speed mixing machine.

Description

technical field [0001] The invention belongs to the technical field of degradable film, and in particular relates to a mechanism and a preparation method of bio-based degradable cotton planting mulch. Background technique [0002] With the rapid development of the economy, people's damage to the environment is becoming more and more serious, especially non-degradable plastics, which are not easy to be degraded by soil microorganisms after being randomly thrown away by people, remain in the soil for a long time, causing serious pollution to the ecological environment . Disposable tableware, disposable plastic products and agricultural mulch are difficult to recycle, and the traditional treatment methods are mainly incineration and landfill. Incineration will produce a large amount of harmful gas, which pollutes the environment; burial means that the polymers in it cannot be decomposed by microorganisms in a short time, which also pollutes the environment. The residual plast...

Problems solved by technology

However, because some raw materials are in the form of fine particles and some raw materials are in the form of powder, there is a phenomenon that the mixing effect is not good. In addition, after the powdery raw materials are weighed, they will stick to a part of the inner wall of the weighing bucket, and this part will not be poured In the high-speed mixer, errors in the weight ratio of raw materials and waste of raw materials
