Needle removal device of geotechnical cloth

Abstract

The invention discloses a needle-removing device for geotextiles. A rotary cylinder is arranged between two front and rear fixed plates, and a shaft is arranged at the middle part of the front and rear ends of the rotary drum, and the shaft is connected to the fixed plate in rotation. The shaft of the shaft passes through the fixed plate and is connected with a second motor. The outer end of the rotating cylinder is provided with soft bristles in the circumferential direction, and the bristles are against the connection between the scraper and the magnet cylinder, and a geotextile is interspersed between the two magnet cylinders. And the geotextile is wound in from the upper side of the magnet cylinder on the left side. The geotextile passes between the two magnet cylinders, so that the geotextile will bend, thus ensuring the contact between the geotextile and the magnet cylinder. The rotating magnet cylinder will suck down the broken needle on the geotextile and drive it. When the scraper is blocked, the rotating bristles will sweep the broken needle to the material receiving box, and be absorbed by the magnet block in the material receiving box, so that the broken needle can be removed from the magnet barrel in time to avoid the broken needle on the magnet barrel The rotation will cause secondary damage to the geotextile, affecting the quality and making it more convenient to use.

Description

technical field [0001] The invention relates to the technical field of removing needles in geotextile production, in particular to a needle removing device for geotextiles. Background technique [0002] Geotextile, also known as geotextile, is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving. The finished product is cloth-like, generally 4-6 meters wide and 50-100 meters long. Geotextiles are divided into woven geotextiles and non-woven geotextiles. Geotextiles have excellent functions of filtration, drainage, isolation, reinforcement, anti-seepage, and protection. They are light in weight, high in tensile strength, good in permeability, high temperature resistance, freezing resistance, aging resistance, and corrosion resistance. In the production process of geotextiles, there will be many broken needles, which will cause certain damage to the production equipment and affect the operation and service life of the equipment.
