Description

Technical Field

[0001] This invention relates to the field of wool fabric weaving technology, specifically a warp-knitted wool fabric weaving apparatus and method. Background Technology

[0002] In the finishing stage of warp-knitted wool fabrics, in order to give the fabric shrinkage resistance, anti-pilling, softness, deepening or specific functions (such as antibacterial, waterproof, etc.), it is often treated with padding finishing solution. At the same time, in order to enhance the added value and aesthetics of the product, such fabrics are often processed with advanced warp knitting technology to form three-dimensional patterns, such as three-dimensional jacquard, embossed texture, etc., so that the surface presents a regular or irregular undulating shape.

[0003] However, the warp knitting process results in a relatively tight coil structure and dense fiber arrangement in the fabric. This makes it difficult for the finishing solution to quickly penetrate into the fiber interior and the bottom layer of the fabric, especially in the three-dimensional pattern area. The raised pattern area has multiple layers of fiber stacked and densely arranged, which further exacerbates the penetration difficulty. In addition, during the rolling action after soaking, the rolling roller can only make close contact and apply pressure to the highest raised part of the three-dimensional pattern. It cannot achieve effective contact and pressing on the lower concave areas, which seriously affects the wetting and adhesion effect of the finishing solution and makes it difficult to guarantee the final product quality of the warp-knitted wool fabric.

[0004] Therefore, the present invention proposes a warp-knitted wool fabric weaving apparatus and method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a warp-knitted wool fabric weaving apparatus and method to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A warp-knitted wool fabric weaving apparatus, designed for padding finishing solutions of warp-knitted wool fabrics containing three-dimensional patterns, includes: Immersion tank for holding finishing solution; A rubbing component used to rub the fabric to promote the penetration of the finishing liquid; Two sets of opposing pressing assemblies are used to press the fabric. The fabric is intermittently transported between the two sets of pressing assemblies. Each pressing assembly includes a mounting member that can move / reset in the direction of the fabric transport path. The mounting member is seamlessly arrayed with pressing members whose ends contact the fabric. During the stroke of the mounting member in contact with the fabric, it can adaptively move axially according to the protrusion of the point of contact with the fabric, and the contact force between each mounting member and the fabric is the same.

[0007] In one alternative embodiment: the kneading assembly includes two parallel kneading members with an adjustable distance between them and two first telescopic members for driving the two kneading members to reciprocate. The two kneading members reciprocate in opposite directions, and the fabric is conveyed between the two kneading members. Flexible protrusions are evenly distributed on the opposite sides of the two kneading members.

[0008] In one alternative: the kneading component is hollow and has a piston plate and several second telescopic components for driving the piston plate to move back and forth; liquid holes are also evenly distributed on the opposite sides of the two kneading components; and the piston plates in the two kneading components move synchronously in the same direction.

[0009] In one alternative: the immersion tank is provided with a support member, and either of the two kneading members is slidably disposed on the support member. The weaving device further includes a third telescopic member for driving the kneading member disposed on the support member toward / away from the other kneading member.

[0010] In one alternative: the pressing member is provided with a sliding rod, the mounting member is provided with slots that correspond to and fit the sliding rods one by one, the end of the sliding rod away from the pressing member passes through the corresponding slot and is provided with a limiting boss, and a magnetic cylinder is provided in the slot that is coaxial with the corresponding sliding rod and magnetically attracted to it.

[0011] In one alternative: the rolling assembly further includes several fourth telescopic members for driving the mounting components to move / reset in the direction of the fabric transport path.

[0012] In one alternative: the pressure element is planar at one end of the fabric transport path.

[0013] A method for weaving warp-knitted wool fabric, using any of the warp-knitted wool fabric weaving devices described in the above technical solutions, includes the following steps: S1: Add an appropriate amount of finishing liquid to the immersion tank, and the warp-knitted wool fabric is transferred through the inside of the immersion tank and intermittently transferred between the two sets of pressing components. S2: During the fabric immersion stroke, the fabric is rubbed by the rubbing component to promote the penetration of the finishing liquid. During the fabric pressing stroke, when the fabric stops conveying, the mounting parts in the two sets of pressing components move a set distance in the direction of the fabric conveying path, thereby driving the pressing parts to move accordingly and come into contact with the fabric. The pressing parts move axially adaptively according to the protrusion of the point of contact with the fabric, and the contact force between each mounting part and the fabric is the same. During the mounting part reset stroke, the fabric is conveyed, and this cycle continues.

[0014] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows: During the fabric impregnation stage, the fabric is rubbed by the rubbing components to promote the penetration of the finishing solution. During the fabric pressing stage, when the fabric stops conveying, the mounting parts in the two sets of pressing components move a set distance in the direction of the fabric conveying path, thereby driving the pressing parts to move accordingly and come into contact with the fabric. The pressing parts move axially adaptively according to the protrusion of the contact point with the fabric, and the contact force between each mounting part and the fabric is the same, realizing indiscriminate pressing of the fabric. This allows the warp-knitted wool fabric with three-dimensional patterns to be efficiently and fully impregnated, improving its impregnation finishing effect and thus ensuring the final product quality of the warp-knitted wool fabric.

Detailed Implementation

[0025] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Please see Figures 1-3 A warp-knitted wool fabric weaving apparatus, designed for impregnation and finishing solutions of warp-knitted wool fabrics containing three-dimensional patterns, comprising: 2. Immersion tank for holding finishing solution; 3. A rubbing component used to rub the fabric to promote the penetration of the finishing liquid; Two sets of opposing pressing assemblies 9 are used to press the fabric. The fabric is intermittently transported between the two sets of pressing assemblies 9. Each pressing assembly 9 includes a mounting member 901 that can move / reset in the direction of the fabric transport path. The mounting member 901 is seamlessly arrayed with pressing members 902 whose ends contact the fabric. During the stroke of the mounting member 901 in contact with the fabric, it can adaptively move axially according to the protrusion of the point of contact with the fabric, and the contact force between each mounting member 901 and the fabric is the same.

[0027] It should be noted that the end of the pressing element 902 facing the fabric transmission path is planar, and the pressing element 902 is relatively thin. The contact force between the pressing element 902 and the warp-knitted wool fabric is controlled within an appropriate and reasonable range, which ensures the pressing effect on the fabric without causing puncture damage to the fabric.

[0028] First, an appropriate amount of finishing liquid is added to the immersion tank 2. Then, the warp-knitted wool fabric (hereinafter referred to as "fabric") is conveyed through the immersion tank 2 (immersed in the finishing liquid) and intermittently conveyed between the two sets of pressing components 9 (the fabric can be continuously conveyed during the immersion phase or intermittently conveyed synchronously with the pressing phase; this application does not limit this). During the fabric immersion phase, the fabric is rubbed by the rubbing component 3 (warp-knitted wool fabric has excellent elastic recovery and rubbing resistance, and the rubbing force of the rubbing component 3 is within a reasonable range and will not cause rubbing damage to the fabric) to promote the penetration of the finishing liquid. During the fabric pressing phase, when the fabric is not conveyed, the mounting parts 901 in the two sets of pressing components 9 move towards the fabric conveying path. The set distance drives the pressing element 902 to move accordingly, thus contacting the fabric (at the end of the fabric transport path facing the pressing element 902). The pressing element 902 moves axially adaptively according to the protrusion of the point of contact with the fabric (that is, the pressing element 902 corresponding to the raised part of the pattern on the fabric stops first, and the pressing element 902 corresponding to the concave part of the fabric continues to move until the end contacts the fabric). The contact force between each mounting element 901 and the fabric is the same (that is, the rolling pressure is the same), so as to achieve non-discriminatory rolling of the fabric. During the reset stroke of the mounting element 901, the fabric is transported. This cycle is repeated so that the warp-knitted wool fabric with three-dimensional pattern is efficiently and fully impregnated, improving its impregnation and finishing effect, and thus ensuring the final product quality of the warp-knitted wool fabric.

[0029] Please see Figure 2 In one embodiment of the present invention, the kneading assembly 3 includes two parallel kneading members 301 with an adjustable distance between them and two first telescopic members 302 (the first telescopic members 302 are electric telescopic rods, telescopic cylinders, etc. in the prior art) for driving the two kneading members 301 to reciprocate. The two kneading members 301 reciprocate in opposite directions, and the fabric is transported between the two kneading members 301. Flexible protrusions 303 (such as those made of soft materials such as silicone or rubber) are evenly distributed on the opposite sides of the two kneading members 301.

[0030] In this embodiment, the fabric is conveyed between two kneading members 310. The two first telescopic members 302 drive the two kneading members 301 to move back and forth in opposite directions. Combined with the protrusions 303 contacting the fabric, the fabric is kneaded. Through the kneading action, the fabric fibers undergo reciprocating deformation and displacement, physically opening the capillary channels between the fibers, thereby significantly promoting the penetration of the finishing liquid.

[0031] Furthermore, in this embodiment, the kneading component 301 is hollow inside and is provided with a piston plate 4 and several second telescopic components 5 for driving the piston plate 4 to reciprocate (the second telescopic component 5 is an electric telescopic rod, telescopic cylinder, etc. in the prior art). Liquid holes 6 are also evenly distributed on the opposite sides of the two kneading components 301. The piston plates 4 in the two kneading components 301 move synchronously in the same direction. The piston plates 4 are driven to reciprocate by the second telescopic components 5 to perform liquid extraction / pushing actions. The piston plates 4 in the two kneading components 301 move synchronously in the same direction, that is, one performs liquid extraction on one side of the fabric and the other performs liquid pushing on the other side of the fabric, thereby forming a unidirectional liquid flow impact on the fabric. While kneading the fabric, the liquid flow impact on the fabric further promotes the penetration of the finishing liquid.

[0032] Furthermore, in this embodiment, the impregnation tank 2 is provided with a support member 7, and any one of the two kneading members 301 is slidably disposed on the support member 7. The weaving device also includes a third telescopic member 8 (the third telescopic member 8 is an electric telescopic rod, telescopic cylinder, etc. in the prior art) for driving the kneading member 301 disposed on the support member 7 to move toward / away from the other kneading member 301. The distance between the two kneading members 301 is adjusted by the extension and retraction of the third telescopic member 8 to adapt to fabrics of different thicknesses and to facilitate the initial arrangement of the fabric before impregnation.

[0033] Please see Figure 2 , Figures 4-7 In one embodiment of the present invention, the pressing member 902 is provided with a sliding rod 904, and the mounting member 901 is provided with a slot 906 that corresponds to and is adapted to the sliding rod 904. The end of the sliding rod 904 away from the pressing member 902 passes through the corresponding slot 906 and is provided with a limiting boss 905. A magnetic cylinder 907 coaxial with the corresponding sliding rod 904 and magnetically attracted to it is provided in the slot 906. Preferably, the sliding rod 904 is made of permanent magnet material.

[0034] In this embodiment, the contact force between the pressing member 902 and the fabric is determined by the magnetic attraction between the pressing member 902 and the slide bar 904, and this force does not change during the extension and retraction of the pressing member 902, thereby achieving the same contact force between the mounting member 901 and the fabric, realizing indiscriminate pressing of the fabric. The mounting member 901 moves a set distance in the direction of the fabric transport path, thereby driving the pressing member 902 to move accordingly, thereby contacting the fabric and moving axially adaptively. The pressing member 902 corresponding to the raised part of the pattern on the fabric stops first, and the pressing member 902 corresponding to the concave part of the fabric continues to move until the end contacts the fabric. During the reset stroke of the mounting member 901, the pressing member 902 is pushed back to the flat state by contacting the inner wall of the immersion tank 2 with the limiting boss 905. This cycle is repeated to press the fabric.

[0035] Furthermore, in this embodiment, the rolling assembly 9 also includes a plurality of fourth telescopic members 903 for driving the mounting member 901 to move / reset in the direction of the fabric transport path (the fourth telescopic member 903 is an electric telescopic rod, telescopic cylinder, etc. in the prior art).

[0036] The present invention also provides a method for weaving warp-knitted wool fabric, using any of the warp-knitted wool fabric weaving devices described in the above technical solutions, comprising the following steps: S1: Add an appropriate amount of finishing liquid to the immersion tank 2. The warp-knitted wool fabric is transferred through the immersion tank 2 and intermittently transferred between the two sets of rolling components 9. S2: During the fabric immersion stroke, the fabric is rubbed by the rubbing component 3 to promote the penetration of the finishing liquid. During the fabric pressing stroke, when the fabric stops conveying, the mounting parts 901 in the two sets of pressing components 9 move a set distance in the direction of the fabric conveying path, thereby driving the pressing parts 902 to move accordingly and contact the fabric. The pressing parts 902 move axially adaptively according to the protrusion of the contact point with the fabric, and the contact force between each mounting part 901 and the fabric is the same. During the reset stroke of the mounting parts 901, the fabric is conveyed, and this cycle continues.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
