Straw is a general term for the stem and leaf parts of mature crops, and generally refers to the residual parts of wheat, rice, corn and other crops after harvesting seeds. During the growth process, more than half of the products of crop photosynthesis exist in the straws, and the straws are rich in nitrogen, phosphorus, potassium, calcium, magnesium, organic matters and the like, so that the straw is a multipurpose renewable biological resource. Because the straws have no direct and favorable use value, a large amount of straws, wheat straws and other straws are always burnt in the field in summer and autumn and winter every year to generate a large amount of dense smoke, which becomes an urgent problem for environmental protection.
With the technological progress and innovation, the straw recycling method finds multiple purposes for the comprehensive development and utilization of crop straws, and not only can the traditional straw returning field be used as a fertilizer, but also new ways such as straw feed, straw vaporization, straw weaving, straw power generation, straw ethanol, straw building materials and the like are provided, so that the utilization value and the utilization rate of the straws are greatly improved.
The straw mat woven by straw has wide application, can be used for product packaging, serving as an intermediate medium, surface protection and the like, and is a relatively direct recycling treatment mode. In the existing weaving equipment, although straw weaving can be realized, the following defects generally exist:
the straws are changed into a continuous and fluffy shape after being fully scattered, so that the straws are easy to interfere with knitting needles and knitting threads during knitting to influence normal knitting; in addition, as the straw is conveyed forwards by the conveying belt, the knitting needle sews once at regular intervals (time), and the feeding amount of the fluffy straw is not a fixed value, so that the thickness of the straw sewn every time is different, and the grain thickness of the knitted straw mat is different.
