Description
Technical Field
The utility model belongs to the hot rolling mill field, concretely relates to hot rolling mill for non-woven fabrics.
Background
The hot rolling is the last web forming technology in the production process of the non-woven fabric, is a process of cooling and spreading the fabric, and is realized by rolling uniform fiber yarns through a high-heat (100-150 ℃) rolling wheel so as to melt the fiber yarns, so that web forming is realized.
The main problems encountered in the production of the non-woven fabric by the existing hot rolling mill are that the tension of the non-woven fabric cannot be ensured, so that wrinkles are easy to appear during rolling; or even if tension is provided, the tension is easy to cause the non-woven fabric to break before hot pressing, so that a new hot rolling machine is urgently needed to solve the pair of contradictions.
SUMMERY OF THE UTILITY MODEL
Not enough more than, the utility model discloses a hot rolling mill for non-woven fabrics.
The technical scheme of the utility model as follows:
a hot rolling mill for non-woven fabrics is characterized by comprising a frame body, a feeding hole, a discharging hole, a preheating roller group, a first guide roller group, a hot pressing roller group, a second guide roller group, a power switch of the preheating roller group and a power switch of the hot pressing roller group; the frame body is rectangular, the feed inlet is positioned at one end of the frame body, and the discharge outlet is positioned at the other end of the frame body; the preheating roller group is positioned at the feed inlet, and the first guide roller group is positioned in the frame body; the second guide roller group is positioned at a discharge port of the frame body, and the hot pressing roller group is positioned between the first guide roller group and the second guide roller group and is fixed above the inside of the frame body; the preheating roller group power switch is positioned on the side of the preheating roller group, and the hot pressing roller group power switch is positioned on the side of the hot pressing roller group. The pre-hot pressing roller set is arranged, the non-woven fabric is pre-pressed and molded to bear certain tension, and then the non-woven fabric is given certain tension through the design of the guide wheel roller set and the hot pressing roller set, so that the non-woven fabric is not wrinkled in the formal hot pressing process, and the pair of contradictions is solved.
Further, in the hot rolling mill for non-woven fabrics, the hot pressing roller group and the first and second guiding roller groups form an isosceles triangle. The structure of an isosceles triangle is formed, so that the hot-pressing roller group is positioned between the first guide roller group and the second guide roller group, the tension on the non-woven fabrics at two sides is consistent, and the fibers are uniformly distributed in the formal hot-pressing process.
Further, in the hot rolling mill for non-woven fabrics, an equilateral triangle is formed between the hot pressing roller group and the first and second guide roller groups. The equilateral triangle is arranged, so that the tension balance of the non-woven fabric is better kept, and the fibers are uniformly distributed in the formal hot pressing process.
Further, according to the hot rolling mill for the non-woven fabric, the roller spacing of the preheating roller group is the same as that of the first guide roller group, and the roller spacing of the hot pressing roller group is the same as that of the second guide roller group.
Further, in the hot rolling mill for non-woven fabrics, the roller distance of the preheating roller set is larger than that of the hot pressing roller set. The pre-hot-pressing distance is larger than the formal hot-pressing distance, so that the pressure of the first hot-pressing is smaller, and the non-woven fabric can bear basic tension.
Further, above-mentioned a hot rolling mill for non-woven fabrics, discharge gate is provided with destaticizing device outward. Static electricity is easily produced to the non-woven fabrics through many hot rolling, sets up static eliminator, can prevent that the non-woven fabrics from piling up together.
Further, in the hot rolling mill for non-woven fabrics, the static removing device is an ion air knife. The ion air knife has the characteristics of simple installation, stable work and high static elimination speed, and simultaneously has the functions of static elimination and dust removal which are combined into a whole, and can blow away dust and fiber fragments remained on the surface in the hot pressing process of the non-woven fabric.
Further, above-mentioned a hot rolling mill for non-woven fabrics, a plurality of gyro wheels are still installed to the bottom of framework. Set up the gyro wheel for the hot rolling mill, conveniently remove the hot rolling mill, make the flexibility of production increase.
Further, above-mentioned hot rolling mill for non-woven fabrics, the gyro wheel is 4 rollers that can fix. When the hot rolling mill is not required to move, the roller is fixed, so that the roller is more stable during work.
According to the technical scheme provided by the utility model, the utility model discloses following beneficial effect has: the utility model discloses a set up hot pressing roll set in advance, carry out hot pressing in advance to the non-woven fabrics raw materials that gets into the feed inlet, give the tensile structure of its one of initial tolerance, through the design of leading wheel roll set and hot pressing roll set afterwards, give the certain tension of non-woven fabrics, make it be unlikely to wrinkle at the hot pressing in-process, solved not have tension to wrinkle easily and tension is too big easy cracked contradiction, set up static-removing device at the discharge gate simultaneously, detach the static and the dust that the non-woven fabrics carried.
