Hot rolling device for non-woven fabric production and hot rolling method thereof

Abstract

The invention discloses a hot rolling device for non-woven fabric production and a hot rolling method thereof, and relates to the technical field of non-woven fabric production. The hot rolling device for non-woven fabric production comprises a box body, wherein a heating device is fixedly installed in the center of the inner side of the bottom of the box body, a transmission device is fixedly installed at the left end of the inner side of the bottom of the box body, a hot rolling mechanism is arranged at the upper end of the inner side of the box body, the box body comprises a feeding port, a discharging port and heat dissipation holes, the feeding port is formed in the upper end of the left side of the box body, the discharging port is formed in the upper end of the right side of the box body, the heat dissipation holes are formed in the left end, close to the bottom, of the front face of the box body, the heating device comprises a heating bin, a heating wire and a conveying pipe, and the heating bin is fixedly installed in the center of the inner side of the bottom of the box body. According to the hot rolling device for non-woven fabric production, the heating mechanism is arranged to be matched with the hot rolling mechanism, high-temperature water vapor formed in the heating mechanism is fed into the surface of the hot rolling mechanism, hot rolling is conducted on non-woven fabric, and therefore heat dissipated during hot rolling of the device is even.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric production, in particular to a non-woven fabric production hot-rolling device and a hot-rolling method thereof. Background technique [0002] Non-woven fabrics mostly use polypropylene (PP) pellets as raw materials, which are a new generation of environmentally friendly materials. They are moisture-proof, breathable, flexible, light, easy to decompose, and recyclable. Commonly used equipment for cloth production; while the general hot rolling device for non-woven fabric production uses heating wire to heat the rotating roll, so that the high-temperature roll performs hot rolling treatment on the non-woven fabric. [0003] In the current hot rolling device for non-woven fabric production on the market, the use of heating wires is likely to cause uneven heating, and after the heating wires heat the hot rolls, the non-working parts of the hot rolls dissipate heat, resulting in unnecessary he...
