Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and in particular to a spunlace jacquard fabric device. Background Technology

[0002] Spunlace fabric, also known as spunlace nonwoven fabric, is a nonwoven material formed by injecting high-pressure water into a fiber web, causing the fibers to intertwine and creating a strong and intact structure. However, due to limitations in the equipment on spunlace production lines, existing jacquard spunlace nonwoven fabrics are all single-sided jacquard, resulting in a weak three-dimensional effect and failing to meet the market demand for double-sided jacquard effects from high-end customers.

[0003] In response, patent document CN209468572U discloses a spunlace double-sided jacquard device. This device has two support columns fixedly mounted on a base, with a top plate fixedly connected to the upper end of each column. Symmetrical mounting openings are provided on the two support columns, and bearings are fixedly installed in each opening. A rotating shaft is inserted into each bearing, and the outer wall of the rotating shaft is fixedly connected to the inner ring of the bearing. Clamping mechanisms are installed at opposite ends of the two bearings, and the two clamping mechanisms are connected by a connecting rod. A drive mechanism is connected to the rotating shaft on the right side to drive its rotation. In use, the nonwoven fabric to be processed is fixed by the clamping mechanisms, and the rotating shaft is driven by the drive mechanism to rotate, thereby driving the clamping mechanisms to rotate and flip the nonwoven fabric, thus achieving the purpose of double-sided jacquard weaving of the spunlace fabric.

[0004] However, although the above-mentioned device can clamp the non-woven fabric through the clamping mechanism and flip the non-woven fabric after completing the jacquard on one side to perform jacquard treatment on the un-jacquard side, thereby achieving the purpose of jacquard on both sides, the above-mentioned device needs to perform jacquard treatment on both sides of the non-woven fabric in sequence, which requires a long processing cycle, resulting in low production speed and reduced economic benefits for enterprises. Utility Model Content

[0005] This invention provides a spunlace jacquard fabric device to solve the technical problem that the long processing cycle of existing spunlace double-sided jacquard devices leads to low production efficiency for enterprises.

[0006] To solve the above problems, the spunlace jacquard fabric device provided by this utility model adopts the following technical solution:

[0007] A spunlace jacquard fabric device, comprising:

[0008] A carding machine, used to card fiber webs;

[0009] A hydroentangling machine, located in the conveying direction of the fiber web and after the carding machine, is used to reinforce the fiber web;

[0010] The jacquard assembly is located in the conveying direction of the fiber web and between the carding machine and the hydroentangling machine. The jacquard assembly includes an upper jacquard pressure roller and a lower jacquard pressure roller arranged correspondingly above and below each other, and a conveying channel for conveying the fiber web is formed between the upper jacquard pressure roller and the lower jacquard pressure roller.

[0011] The surface of the upper jacquard roller is provided with a plurality of first concave holes, and the surface of the lower jacquard roller is provided with a plurality of second concave holes.

[0012] The beneficial effects of the spunlace jacquard device provided by this utility model are as follows: By setting a jacquard assembly including an upper jacquard pressure roller and a lower jacquard pressure roller between the carding machine and the spunlace machine, when the upper and lower jacquard pressure rollers rotate and correspond to the positions of the first and second concave holes, a negative pressure is formed between them to draw the fiber web and gather the nearby fibers at the first and second concave holes. When the positions of the first and second concave holes no longer correspond, the negative pressure between them disappears, leaving the fiber aggregation point on the fiber web. During subsequent spunlace, a double-sided convex pattern can be formed on the surface of the fiber web. During the processing, double-sided jacquard can be achieved without flipping the fiber web, which greatly shortens the processing cycle of double-sided jacquard spunlace fabric, thereby improving the production efficiency and economic benefits of enterprises.

[0013] Through the above-mentioned design, this utility model has improved and upgraded the existing spunlace jacquard device, effectively solving the technical problem that the long processing cycle of the existing spunlace double-sided jacquard device leads to low production efficiency for enterprises.

[0014] Furthermore, the plurality of the first concave perforations are arranged in a matrix on the surface of the upper jacquard pressure roller.

[0015] Furthermore, the plurality of second concave perforations are arranged in a matrix on the surface of the lower jacquard pressure roller.

[0016] Furthermore, both the first concave pore and the second concave pore are provided with filter screens.

[0017] Furthermore, the filter screen is an arc-shaped filter screen.

[0018] Furthermore, the fiber length of the web is 5–60 mm.

[0019] Furthermore, the hydroentangling pressure range of the hydroentangling machine is 5 bar to 30 bar. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] It should be noted that the main concept of the spunlace jacquard device provided by this utility model is as follows: by setting a jacquard assembly including an upper jacquard pressure roller and a lower jacquard pressure roller between the carding machine and the spunlace machine, and setting a first concave pattern and a second concave pattern on the upper jacquard pressure roller and the lower jacquard pressure roller respectively, when the upper jacquard pressure roller and the lower jacquard pressure roller rotate, when the first concave pattern and the second concave pattern are aligned vertically, a negative pressure that can draw the fiber web can be formed between them, so as to gather the nearby fibers at the first concave pattern and the second concave pattern. When the first concave pattern and the second concave pattern are staggered vertically, the negative pressure between them disappears, so that the fiber gathering point remains on the web, thereby forming a two-sided convex pattern on the fabric surface of the fiber web in the subsequent spunlace process.

[0028] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0029] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0030] Example 1 of the spunlace jacquard device provided by this utility model:

[0031] like Figures 1 to 3 As shown, the spunlace jacquard device includes a carding machine 1, a spunlace machine 3, and a jacquard assembly. The carding machine 1 is used to card the fiber web 2. The spunlace machine 3 is located in the conveying direction of the fiber web 2 and is positioned after the carding machine 1 to reinforce the fiber web 2. The jacquard assembly is located in the conveying direction of the fiber web 2 and is positioned between the carding machine 1 and the spunlace machine 3.

[0032] The following describes the structural composition of the jacquard assembly. The jacquard assembly includes an upper jacquard pressure roller 4 and a lower jacquard pressure roller 5 arranged correspondingly. A conveying channel for conveying the fiber web 2 is formed between the upper jacquard pressure roller 4 and the lower jacquard pressure roller 5. The surface of the upper jacquard pressure roller 4 is provided with a plurality of first concave holes 6, and the surface of the lower jacquard pressure roller 5 is provided with a plurality of second concave holes 7.

[0033] Specifically, multiple first concave holes 6 are arranged in a matrix on the surface of the upper jacquard roller 4, and multiple second concave holes 7 are arranged in a matrix on the surface of the lower jacquard roller 5.

[0034] Specifically, a filter screen is provided in both the first concave pit 6 and the second concave pit 7, and both filter screens are arc-shaped filter screens 8.

[0035] In addition, it should be noted that the fiber length of the web 2 is 5 to 60 mm, and the hydroentangling pressure range of the hydroentangling machine 3 is 5 bar to 30 bar.

[0036] The working principle of the spunlace jacquard device provided by this utility model is as follows: During the conveying process of the fiber web 2, the carding machine 1 combs the fibers in the fiber web 2 to remove impurities and make the fibers in the fiber web 2 neatly arranged. Then, the fiber web 2 enters the conveying channel and is conveyed forward as the upper jacquard pressure roller 4 and the lower jacquard pressure roller 5 rotate. When the first concave hole 6 and the second concave hole 7 are aligned, a negative pressure is formed between the two holes to draw the fiber web 2, gathering the nearby fibers at the first concave hole 6 and the second concave hole 7. When the first concave hole 6 and the second concave hole 7 are no longer aligned, the negative pressure formed between the two holes disappears, leaving the fiber aggregation point on the fiber web 2. Subsequently, the fiber web 2 is conveyed to the spunlace machine 3. During the spunlace process of the spunlace machine 3, convex patterns on both sides of the fabric surface can be formed, thus obtaining double-sided jacquard spunlace nonwoven fabric.

[0037] Example 2 of the spunlace jacquard device provided by this utility model:

[0038] Its main difference from Example 1 is:

[0039] In Example 1, multiple first concave holes are arranged in a matrix on the surface of the upper jacquard roller, and multiple second concave holes are arranged in a matrix on the surface of the lower jacquard roller.

[0040] In this embodiment, a plurality of first concave holes and a plurality of second concave holes are arranged on the surface of the upper jacquard pressure roller and the surface of the lower jacquard pressure roller, respectively, and the arrangement shape is determined according to the specific application requirements.

[0041] Example 3 of the spunlace jacquard fabric device provided by this utility model:

[0042] Its main difference from Example 1 is:

[0043] In Example 1, the filter screen is an arc-shaped filter screen.

[0044] In this embodiment, the filter is a square filter or a polygonal filter.
