Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric production technology, and specifically to a nonwoven fabric coating machine. Background Technology

[0002] As is generally known, nonwoven fabric is a sheet, web, or mat made of fibers arranged in a directional or random pattern, bonded together through friction, cohesion, or adhesion, or a combination of these methods. Nonwoven fabric is characterized by its moisture-proof, breathable, flexible, lightweight, non-flammable, easily degradable, non-toxic, non-irritating, rich in colors, inexpensive, and recyclable properties. Therefore, nonwoven fabric is also called non-woven cloth. During production, a coating is applied to the surface of the nonwoven fabric to meet production needs, and then it is cut and wound up to the required dimensions. Generally, a set size is set during winding, and the fabric is wound up using appropriate winding rollers.

[0003] For example, the Chinese patent with authorization announcement number "CN 112278954 B" entitled "A Nonwoven Fabric Winding Device" describes a winding device that can automatically wind, cut, and change rolls of nonwoven fabric. The device is driven by a roll transfer mechanism to rotate the support in a circular motion at the roll loading position, the roll parking position, and the roll unloading position. The support carries the roll and performs winding, cutting, and unloading in sequence. It has a high degree of automation, which can significantly improve the rolling efficiency of nonwoven fabric, reduce manual labor, and improve safety.

[0004] The shortcomings of the prior art are as follows: In the prior art, such as the aforementioned patent, if different widths of nonwoven fabric are required during winding, the winding roller needs to be changed to adapt to the winding width. In the prior art, winding can only be carried out by changing to a winding roller with an appropriate width, which is not only inefficient but also wastes the cost of the winding roller. Summary of the Invention

[0005] The purpose of this invention is to provide a nonwoven fabric coating machine to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

The fixed frame is provided with two take-up rollers, and each take-up roller is provided with a plurality of take-up components. Adjacent take-up components are connected to each other through an adjusting component.

[0008] During the width adjustment, each of the winding components slides open at equal intervals by adjusting the components, and at the same time as sliding open, each of the winding components adjusts the width synchronously.

[0009] As a further preferred scheme of the embodiment of the present application, the winding assembly on one of the winding rollers is staggered with the winding assembly on the other winding roller, and the distance between the adjacent winding assemblies on the same winding roller is equal to the width of the winding assembly.

[0011] As a further preferred scheme of the embodiment of the present application, the first winding roller and the third winding roller are driven to slide synchronously when the adjusting assembly moves. In this embodiment, the movement of the adjusting assembly can drive the first winding roller and the third winding roller to slide relative to the second winding roller, i.e. the width of the winding assembly can be adjusted.

[0012] As a further preferred scheme of the embodiment of the present application, the adjusting assembly comprises two connecting members rotatably arranged, and the two connecting members are cross arranged, the connecting member comprises a plurality of adjusting plates rotatably arranged, and the adjusting plate at the edge of each connecting member is movably arranged in the long slot formed on the second winding roller.

[0013] As a further preferred scheme of the embodiment of the present application, one of the adjusting plates on each connecting member is provided with an inner protruding column, and the inner protruding column can be inserted into the limiting slot formed on the first winding roller and the third winding roller.

[0014] As a further preferred scheme of the embodiment of the present application, the fixing frame is further provided with a first guide roller and a second guide roller, the non-woven fabric passes through the second guide roller and the first guide roller and is cut by the cutting assembly.

[0015] As a further preferred scheme of the embodiment of the present application, the cutting assembly comprises a cutting roller rotatably arranged on the fixing frame, and the cutting roller is provided with a plurality of cutting knives, and each cutting knife contacts the first guide roller.

[0016] As a further preferred scheme of the embodiment of the present application, the surface of the adjusting plate is arranged in a curved shape and is attached to the winding roller.

[0017] As a further preferred scheme of the embodiment of the present application, the conveying belt is further provided with a coating mechanism, and the coating mechanism is arranged upstream of the winding roller.

[0018] In the above technical scheme, the non-woven fabric coating machine provided by the present application has the following beneficial effects:

[0019] The present application can greatly improve the winding efficiency by setting two winding rollers and a plurality of winding assemblies on the two winding rollers, and the winding assemblies and the adjusting assembly are used in cooperation to make the winding assemblies slide away equidistantly through the adjusting assembly when the width is adjusted, and the winding assemblies are synchronously adjusted in width at the same time, so that the spacing between the winding assemblies on the winding roller and the width of the winding assemblies can be automatically adjusted when the non-woven fabric with different widths needs to be wound, thereby adapting to the non-woven fabric with different widths without replacing the winding roller, greatly improving the winding efficiency and reducing the production cost.

[0037] Please refer to 1-10, a non-woven fabric coating machine, comprising a conveying belt 1 and a fixed frame 3 arranged at one end of the conveying belt 1: the fixed frame 3 is provided with two winding rollers 5, and each winding roller 5 is provided with a plurality of winding assemblies 51, and the adjacent winding assemblies 51 are connected by an adjusting assembly 7;

[0038] When adjusting the width of the non-woven fabric winding, each winding assembly 51 slides away equidistantly through the adjusting assembly 7, and at the same time, each winding assembly 51 is synchronously adjusted in width.

[0039] Specifically, the two winding rollers 5 are provided, and a plurality of winding assemblies 51 are arranged on the two winding rollers 5, that is, the cut non-woven fabric can be wound by the two winding rollers 5 at the same time, so that the winding efficiency can be greatly improved. The cooperation of the winding assembly 51 and the adjusting assembly 7 can make each winding assembly 51 slide away equidistantly through the adjusting assembly 7, and at the same time, each winding assembly 51 is synchronously adjusted in width. When the non-woven fabric with different widths needs to be wound, the distance between the winding assemblies 51 on the winding roller 5 and the width of the winding assembly 51 itself can be automatically adjusted, so that the non-woven fabric with different widths can be adaptively wound, the winding roller 5 does not need to be replaced, the winding efficiency is greatly improved, and the production cost is reduced.

[0040] In the further provided embodiment of the present application, the winding assemblies 51 on one winding roller 5 are staggered with the winding assemblies 51 on the other winding roller 5, and the distance between the adjacent winding assemblies 51 on the same winding roller 5 is equal to the width of the winding assembly 51. Specifically, the distance between the adjacent winding assemblies 51 on the same winding roller 5 is equal to the width of the adjusting assembly 7, and since the positions of the adjusting assemblies 7 on the two winding rollers 5 are staggered, the cut non-woven fabric can be wound by the winding assemblies 51 on the two winding rollers 5 respectively.

[0041] In the further provided embodiment of the present application, the winding assembly 51 comprises a first winding wheel 511, a second winding wheel 512 and a third winding wheel 513. The first winding wheel 511 and the third winding wheel 513 are respectively arranged on the second winding wheel 512 in a sliding manner, and are arranged on the second winding wheel 512 in the axial direction of the second winding wheel 512. The first winding wheel 511, the second winding wheel 512 and the third winding wheel 513 can slide in the axial direction of the winding roller 5, but cannot rotate in the circumferential direction. The first winding wheel 511 is provided with a limiting protrusion 55, and the second winding wheel 512 is provided with a synchronous groove 5101 matched with the limiting protrusion 55, so that the first winding wheel 511 and the third winding wheel 513 can move synchronously.

[0042] Further, the first winding wheel 511 and the third winding wheel 513 are driven to slide synchronously by the adjusting assembly 7. In the embodiment, the movement of the adjusting assembly 7 can drive the first winding wheel 511 and the third winding wheel 513 connected thereto to slide relative to the second winding wheel 512, so as to adjust the width of the winding assembly 51.

[0043] Further, the adjusting assembly 7 comprises two rotationally arranged connecting members which are cross arranged, and the connecting members comprise a plurality of rotationally arranged adjusting plates 71, and the adjusting plates 71 at the edges of each connecting member are movably arranged in the long slot 5122 formed on the second winding roller 512. Specifically, the adjusting plates 71 at the edges of the connecting members of the adjacent adjusting assembly 7 are rotationally connected, that is, the adjusting plates 71 at the edges of the connecting members of the adjacent adjusting assembly 7 are rotationally connected and rotationally arranged on the second winding roller 512, that is, each adjusting assembly 7 is rotationally connected through the adjusting plates 71 at the edges, and rotationally connected with the second winding roller 512, and the position where the second winding roller 512 rotationally arranged is provided with the long slot 5122, and the adjusting plate 71 is slidably arranged in the long slot 5122.

[0044] Further, one of the adjusting plates 71 on each connecting member is provided with an inner protruding column 5121 which can be inserted into the limiting slot 5111 formed on the first winding roller 511 and the third winding roller 513. Specifically, when adjusting, the two cross rotationally arranged connecting member supports are relatively rotated, and since the adjusting plates 71 at the edges are rotationally arranged on the second winding roller 512, when rotated, the second winding roller 512 connected therewith can be relatively slid and slide along the winding roller 5, and the sliding distance is consistent, that is, the distance between each second winding roller 512 can be adjusted, and then during the adjusting process, since the inner protruding column 5121 is inserted into the limiting slot 5111, when the adjusting plate 71 is rotated, the inner protruding column 5121 can be synchronously rotated, and since the limiting of the limiting slot 5111, the first winding roller 511 and the third winding roller 513 can be relatively slid with the second winding roller 512, that is, the sliding distance of the first winding roller 511 and the third winding roller 513 relative to the second winding roller 512 can be adjusted, that is, the width of the winding assembly 51 can be integrally adjusted to adapt to the winding of non-woven fabrics of different widths.

The adjusting plate 71 provided in the present application can be attached to the winding roller 5, thereby facilitating the movement of the adjusting plate 71.

[0048] Furthermore, the conveying belt 1 is further provided with a coating mechanism 2, and the coating mechanism 2 is arranged upstream of the winding roller 5.

[0049] The winding assembly 51 provided in the present embodiment is arranged to be capable of winding the conveying belt 1 around the winding roller 5. Figure 2As shown, the leftmost winding assembly 51 is fixed on the winding roller 5, and then the rightmost winding assembly 51 is pulled, and during the pulling, the whole winding assembly 51 is gradually moved, since the adjacent winding assemblies 51 are connected through the adjusting assembly 7, so when the winding assembly 51 is pulled, the whole winding assembly 51 on the winding roller 5 can be synchronously slid through the action of the adjusting assembly 7, and during the sliding, since the leftmost winding fixing shaft is fixed in position, each winding assembly 51 can slide, and during the sliding, the two adjusting plates 71 rotatably arranged on each adjusting assembly 7 rotate, so that the adjusting plate 71 in the elongated groove 5122 slides along the elongated groove 5122, that is, the second winding roller 512 is pushed to slide along the winding roller 5, and the sliding distance of each second winding roller 512 is consistent, so that it is equally spaced apart, that is, the distance of each second winding roller 512 can be adjusted, and during the adjustment, the adjusting plate 71 provided with the inner protruding column 5121 also moves, since the inner protruding column 5121 is inserted into the limiting groove 5111, when the adjusting plate 71 rotates, the inner protruding column 5121 can be synchronously rotated, and since the limiting groove 5111 limits, the first winding roller 511 and the third winding roller 513 can be slid relative to the second winding roller 512, that is, the sliding distance of the first winding roller 511 and the third winding roller 513 relative to the second winding roller 512 can be adjusted, that is, the width of the winding assembly 51 can be adjusted as a whole, so that the adjusting assembly 7 can be equally spaced apart, and the first winding roller 511 and the third winding roller 513 on the winding assembly 51 can be simultaneously expanded or contracted, and can be equally spaced apart, that is, the present application can simultaneously wind the cut non-woven fabric through the two winding rollers 5, so as to greatly improve the winding efficiency, and through the cooperation of the winding assembly 51 and the adjusting assembly 7, when the width is adjusted, each winding assembly 51 can be equally spaced apart through the adjusting assembly 7, and at the same time, each winding assembly 51 can be synchronously adjusted in width, so that when the non-woven fabric with different widths needs to be wound, the distance between the winding assemblies 51 on the winding roller 5 and the width of the winding assembly 51 itself can be automatically adjusted, so as to adapt to the winding of non-woven fabric with different widths, without the need to replace the winding roller 5, greatly improving the winding efficiency and reducing the production cost.
