d. grinding and ironing, namely cutting a cotton wool layer on a wood roller, placing the cut cotton wool layer on a grinding and ironing machine, and grinding and ironing the cotton wool layer into a quilt; the quilt is formed by overlapping an upper cotton wadding layer and a lower cotton wadding layer; the fiber direction of the upper layer cotton wool is vertical to that of the lower layer cotton wool; sequentially grinding and ironing the upper surface and the lower surface of the quilt;

e. edge covering, namely sewing the edge covering around the grinded and ironed cotton quilt;

f. cleaning and ironing, namely putting the cotton quilt with the edges on a cleaning and ironing machine, and kneading cotton;

g. packaging, and bagging and sealing the cleaned and ironed cotton quilt.

Preferably, the time of each grinding and ironing is 8-10 min. Ensure the air permeability and heat preservation of the cotton wool.

Preferably, the cleaning and ironing time is 25-30 min. Ensure the cotton kneading effect and improve the cotton fiber quality.

Preferably, before the grinding and ironing, the exposed cotton wool at the periphery of the quilt is folded, so that the exposed cotton wool is attached to the upper surface of the quilt. After the exposed cotton wool is folded, the smooth contour of the periphery of the ground and ironed cotton quilt can be ensured.

Preferably, the quilt is trimmed before being ironed on its lower surface. Grind after the upper surface of pressing the quilt, the quilt is stereotyped, can be to the quilt according to size cutting edge, then send into the quilt of cutting edge again and grind the machine, can weaken the influence of cutting edge section to the quilt quality.

The method has the beneficial effects that impurities, short fibers and neps in the cotton fibers can be effectively screened out, and the purity of the cotton fibers is high; the cotton wool is soft in texture and good in comfort; the cotton quilt has high structural strength, is not easy to spall and rise, and has high structural strength and long service life.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.

A method for manufacturing a non-net quilt comprises the following steps:

g. packaging, and bagging and sealing the cleaned and ironed cotton quilt.

The scattered flower treatment can ensure the smoothness of the subsequent carding process. In the cotton scattering process, the rotary striking piece can also beat impurities such as residual cotton seeds, broken stones and dust in lint, the purity of cotton wool is guaranteed, and the impurities are prevented from affecting the color and softness of the formed cotton quilt.

When the loose ginned cotton is arranged in the carding machine, the ginned cotton can be subjected to three steps of pre-carding, main carding and layer gathering in the carding machine. The main part of the pre-carding process is a licker-in, the surface of the licker-in is embedded with a sawtooth strip, and a dust removing knife and an arc-shaped drain bottom with meshes or dust bars are arranged below the licker-in. The lint is fed into the licker-in roller by the feeding roller, and the cotton wool on the lint is stripped to form a cotton bundle when the licker-in roller rotates. The dust removal knife box under screen can separate out impurity and short flannel.

The main components of the main carding process are the cylinder and doffer. The cylinder on the carding machine is matched with the cover plate to continuously loosen and carding the cotton bundles, so that the separation degree of fibers is improved, fibrous forward bent hooks are formed, and the straightness, parallelism and uniformity of the cotton fibers are ensured. The cylinder can comb short staple fiber and nep impurity, improves the glossiness on the face fibre, guarantees the quality of weaving shaping cotton-wadded quilt. The doffer on the carding machine can be further carded, and the cotton fibers on the needle surface of the cylinder are condensed on the surface of the doffer to form a loose cotton fiber layer. In order to clean short fibers and neps in time, a fan for cleaning is connected in the cylinder.

In the laminating process, a cotton fiber layer on a doffer is collected by a stripping roller, the cotton fiber layer is sent into a pair of press rollers, and the loose cotton fiber layer is compacted to form thin-layer cotton wool. The thin-layer cotton wool is wound on a wood roller in multiple layers and is stacked into a cotton wool layer.

Cutting the cotton wool layer on the wood roller, and flatly paving the cotton wool layer on a grinding and ironing machine for grinding and ironing treatment to form the quilt. The quilt is formed by overlapping two cotton wool layers from top to bottom, and the fiber direction of the upper cotton wool layer is perpendicular to that of the lower cotton wool layer, so that the overall strength and the tensile strength of the quilt are guaranteed. According to the specification of common quilts for double beds, about 120 layers of thin cotton wool are needed for a quilt with weight of six jin.

The upper and lower surfaces of the quilt are both required to be grinded and ironed. Before the cotton quilt is ironed, the exposed cotton wool at the periphery of the cotton quilt needs to be folded, so that the exposed cotton wool is attached to the upper surface of the cotton quilt. And then, grinding and ironing the upper surface of the quilt by 8-10 min by using a grinding and ironing machine. And turning over the quilt, and performing edge cutting treatment by referring to the scribing lines on the grinding and ironing machine to enable the size of the quilt to meet the specification. And feeding the cotton quilt with the cut edges into a grinding and ironing machine again, and grinding and ironing the lower surface of the cotton quilt by 8-10 min. The grinding and ironing machine enables the cotton fibers on the upper surface and the lower surface of the quilt to be interwoven into a net shape.

The cotton quilt needs to be subjected to edge covering treatment after being grinded and ironed, and the cotton quilt after edge covering needs to be put into a cleaning and ironing device for kneading cotton for 25-30 min, so that the quality of cotton wool is guaranteed. And packaging the cotton quilt after finishing cleaning and ironing.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention.
