Description

Technical Field

[0001] The utility model relates to a quilted fiber cotton and a forming device thereof, in particular to a novel quilted fiber cotton and a forming device thereof. Background Art

[0002] The current quilting fiber cotton mainly uses fluffy fiber cotton, which is formed into a layered material with a certain thickness and can be rolled up through needle punching. It can be used in mattress fabrics, bedding, underwear cotton, clothing and other occasions.

[0003] However, because the current fiber cotton is directly quilted into the fabric, there is no adhesion between the fiber cotton and the fabric, so the fiber cotton is easily pulled, moved, and clumped after washing.

[0004] Taking mattress fabric as an example, the fiber cotton layer is easily stretched and deformed when it is laid, resulting in uneven thickness and affecting the texture of the mattress fabric. Utility Model Content

[0005] One purpose of the utility model is to provide a new type of quilted fiber cotton with simple and reasonable structure and strong tensile strength.

[0006] One purpose of the utility model is achieved in this way:

[0007] A novel quilted fiber cotton comprises a fiber cotton layer, wherein a melt-blown fabric surface layer and a melt-blown fabric bottom layer are attached to the upper and lower sides of the fiber cotton layer.

[0008] One purpose of the utility model can also be solved by the following technical measures:

[0009] As a more specific solution, the thickness of the fiber cotton layer is 10mm-25mm, and the gram weights of the meltblown fabric surface layer and the meltblown fabric bottom layer are 10g / m²-20g / m² respectively.

[0010] As a further solution, the thickness of the fiber cotton layer is 15mm-20mm, and the gram weights of the meltblown fabric surface layer and the meltblown fabric bottom layer are 12g / m²-16g / m² respectively.

[0011] As a further solution, the fiber cotton layer is pre-pressed with the meltblown fabric surface layer and the meltblown fabric bottom layer and then adhered to each other through the plush on the surface of the material.

[0012] Another object of the utility model is to provide a new type of quilting fiber cotton forming equipment which has a simple and reasonable structure and is easy to implement.

[0013] Another purpose of the utility model is achieved in this way:

[0014] A new type of quilting fiber cotton forming equipment, including a conveying channel for conveying fluffy fiber cotton, a needle-punching and weaving mechanism for processing the fluffy fiber cotton into a fiber cotton layer, and a composite extrusion roller for combining a melt-blown cloth surface layer and a melt-blown cloth bottom layer with the fiber cotton layer. The needle-punching and weaving mechanism is arranged above the conveying channel for up and down reciprocating motion. The needle-punching and weaving mechanism includes a lifting plate. A plurality of needles are arranged at the bottom of the lifting plate corresponding to the wide direction of the conveying channel and a certain length range. The needle tips are provided with barbs. The up and down movement stroke of the needle-punching and weaving mechanism is 100 mm-130 mm, and the distance from the needle tip to the surface of the conveying channel is greater than the up and down movement stroke of the needle-punching and weaving mechanism.

[0015] Another purpose of the utility model can also be solved by the following technical measures:

[0016] As a more specific solution, the thickness of the fluffy fiber cotton is greater than the thickness of the fiber cotton layer and less than the up and down movement stroke of the needle-punching weaving mechanism. The thickness of the fiber cotton layer is 10mm-25mm.

[0017] As a further solution, the needles are distributed in a crisscross pattern.

[0018] As a further solution, a pre-extrusion output roller is further provided between the composite extrusion roller and the conveying channel.

[0019] As a further solution, a winding mechanism is further provided behind the composite extrusion roller.

[0020] The beneficial effects of the utility model are as follows:

[0021] (1) The utility model attaches meltblown cloth layers to the upper and lower sides of the fiber cotton layer, so that the plush of the fiber cotton layer is hooked and fitted with the plush on the surface of the meltblown cloth layer, making it difficult for the fiber cotton layer and the meltblown cloth layer to separate and shift relative to each other. Therefore, when pulled, the upper and lower meltblown cloth layers bear the main pulling force to prevent them from deformation. When used for a long time or washed, the fiber cotton layer is always in contact with the meltblown cloth layer, is not easy to move or clump, and its thickness is always uniform.

[0022] (2) The thickness of this new type of fiber cotton in a fluffy state is 5 times the thickness of the final meltblown cloth layer, making the fiber cotton interweaving more dense, further improving its tensile strength and reducing the chance of wire slip (fluff drilling out of the surface cloth).

[0023] (3) This new type of production equipment increases the stroke of the needle weaving mechanism to weave thicker and fluffy fiber cotton, forming a fiber cotton layer with better softness. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Meltblown cloth is a nonwoven fabric made of polypropylene as the main raw material. Its fiber diameter can reach 1 to 5 microns. It has a unique capillary structure and ultrafine fibers, which can effectively increase the number of fibers per unit area. It can be combined with the plush of the fiber cotton layer 1 to play a certain bonding role and prevent the fiber cotton layer and the meltblown cloth layer from moving relative to each other. Meltblown cloth has many gaps, a fluffy structure, is soft and delicate, and has a good sense of comfort. In addition, since the fiber cotton layer 1 is provided with a meltblown cloth surface layer 2 and a meltblown cloth bottom layer 3 on both sides, its tensile strength is improved to prevent uneven thickness due to pulling and deformation.

The up and down motion of the needle-punching and weaving mechanism (see Figure 2 The stroke (indicated by the direction of the arrow A) is 100 mm-130 mm, and the distance from the needle tip to the surface of the conveying channel 4 is greater than the up and down movement stroke of the needle-punching mechanism.

[0033] The thickness of the fluffy fiber cotton 1' is greater than the thickness of the fiber cotton layer 1 and less than the up and down movement stroke of the needle-punching and weaving mechanism. The thickness of the fiber cotton layer 1 is 10mm-25mm.

[0034] The needles 6 are distributed in a crisscross pattern.

[0035] A pre-extrusion output roller 7 is also provided between the composite extrusion roller 8 and the conveying channel 4 .
