Rock wool pleating machine and pleating method thereof

Abstract

The invention relates to a rock wool pleating machine and a pleating method thereof. The pleating machine comprises three groups of upper and lower compression rollers, driving devices of the compression rollers, a device for adjusting intervals between the upper compression rollers and the lower compression rollers, and a first group of upper compression roller tensioning device, wherein the first group, the second group and the third group of compression rollers are connected in sequence and independently driven. The pleating method comprises the following steps of: spreading rock wool fibers, the surface of which are sprayed with adhesives, into multilayer rock wool which is evenly distributed in density through a pendulum bob machine, feeding the multilayer rock wool into the pleating machine, and adjusting the angle of an dip angle of the first group of upper compression roller of the pleating machine and the difference value of the transmission speeds of the first group of upper compression roller and the second group of lower compression roller of the pleating machine to form a forming fold; subsequently feeding the rock wool subjected to first pleating to the third group, and enabling the rock wool to generate a second differential folding structure by adjusting the transmission speed difference of the third group and the second group of compression rollers; feeding pleated rock wool into a curing furnace, carrying out high-temperature curing and pressing into a rock wool product. In the invention, the high-temperature rock wool product with the pleating coefficient not less than 1: 3 is made, the compression strength of the rock wool product in the 10% deformation amount can reach 40-100KPa, and the perpendicular tensile strength thereof can reach 10-20KPa.

Description

technical field [0001] The invention belongs to the technical field of material processing, and in particular relates to rock wool processing equipment and a production method. Background technique [0002] The existing production process of rock wool products in China is to spread the rock wool fibers formed by the cupola blown wire into a multi-layer rock wool layer with uniform density through a pendulum machine, and then send it into the curing furnace for high temperature curing and press it into rock wool products. . The rock wool products produced by this process do not use pleating technology when the rock wool is paved, so that the rock wool fibers in the product are only arranged in two-dimensional layers in the transverse direction, while the rock wool fibers have no arrangement in the thickness direction of the product. Cloth, that is, there is no three-dimensional overlapping and interlocking of rock wool fibers, so the strength of rock wool products, especiall...

AI Technical Summary

Problems solved by technology

The rock wool products produced by this process do not use pleating technology when the rock wool is paved, so that the rock wool fibers in the product are only arranged in two-dimensional layers in the transverse direction, while the rock wool fibers have no arrangement in the thickness direction of the product. Cloth, that is, there is no three-dimensional overlapping and interlocking of rock wool fibers, so the strength of rock wool products, especially the vertical tensile strength, is very low, which cannot meet the performance requirements of rock wool products used in buildings and other industrial thermal insulation products.

[0003] At present, with the development of the national economy and the implementation of the national energy-saving policy, the demand for high-performance rock wool products for building and industrial thermal insulation is increasing, but most of the rock wool products on the market are low-end products. The product has low strength, poor thermal insulation and poor weather resistance, which restricts the development of building and industrial energy conservation
