Description

Technical Field

[0001] The invention relates to the field of porous non-woven fabric production equipment, and more specifically to a porous high-strength composite non-woven fabric punching and slitting device. Background Art

[0002] Porous non-woven fabric is a non-woven material. Due to its pore characteristics, porous non-woven fabric exhibits higher specific strength and specific surface area, so it has the characteristics of good permeability, sound insulation and heat insulation.

[0003] The porous non-woven fabric is formed into a porous structure by needle punching. The porous forming methods are divided into punching before consolidation and punching after consolidation. The pore sizes of the two are generally different, and the application ranges are also different. Punching holes before the fiber web is consolidated makes the distribution and size of the pores easier to control, and a more uniform pore structure can be achieved.

[0004] From the perspective of the structure of multi-layer non-woven fabrics, the gap distance on each single layer is single, which has poor filtering effect, and porous non-woven fabrics with a single pore size may not perform well in terms of air permeability and water permeability. For example, too large a pore size may lead to excessive air permeability, while too small a pore size may lead to insufficient water permeability. Summary of the invention

[0033] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that the description of the present disclosure will be more comprehensive and complete and the concepts of the example embodiments will be fully conveyed to those skilled in the art. The accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and thus their repeated description will be omitted.

[0034] In addition, the described features, structures or characteristics may be combined in one or more example embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the example embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, steps, etc. may be adopted. In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0035] like Figure 1 A porous high-strength composite non-woven fabric punching and slitting device mainly includes a tying roller 1, a frame 2, a reeling frame 3 and a reeling wheel 4. The tying roller 1 is rotatably connected to the frame 2. A motor is arranged on one side of the frame 2. The motor is electrically connected to an external controller and is used to drive the tying roller 1 to rotate under the control of the controller. The output shaft of the motor can be directly connected to the tying roller 1 or can be connected through a transmission. Because it is more common to use a motor to drive the tying roller 1 to rotate, it will not be described in detail.

[0036] Unwinding racks 3 are placed on both sides of the frame 2, and unwinding wheels 4 are rotatably connected inside the unwinding racks 3. The two unwinding wheels 4 are used in conjunction with corresponding power equipment. The power equipment can be a corresponding motor. The power equipment can be directly connected to the unwinding wheel 4 or connected to the unwinding wheel 4 through a transmission. It is not repeated here. The unwinding wheel 4 rotates at a constant speed to quantitatively release or reel in a single layer of non-woven fabric.

[0037] The following embodiments are all improved based on the above structure.

[0038] The slitting device is arranged at the rear side of the unwinding wheel 4 for winding to connect to the next process.

[0039] Example 1

[0040] like Figure 1 and Figure 2The tying roller 1 includes an inner roller column 11 and a slide plate 12. The inner roller column 11 is a hollow cylinder. In order to reduce the manufacturing cost, the lengths of several slide plates 12 fixed along the axial direction of the inner roller column 11 are consistent, and the positions of the tying needles buried on the slide plates 12 are also the same, which is convenient for batch processing and reduces costs.

[0041] When the number of the slide plates 12 is increased, the gap distances of the holes pierced by the inner roller 11 when it rotates one circle become more variable.

[0042] It should be noted that the width of a single layer is smaller than the width of the roller 1 .

[0043] Example 2

[0044] like Figure 2 The tying roller 1 includes an inner roller column 11, a slide plate 12, an end cover 13, a position adjusting member 14 and a connecting plate 15. The inner roller column 11 is a hollow cylinder with an opening at one end. The end cover 13 is connected to the inner roller column 11 by a snap-fit ​​structure or a threaded structure, and can rotate synchronously with the inner roller column 11. Part of the slide plate 12 is slidably connected to the inner roller column 11, and the other part of the slide plate 12 is fixed on the inner roller column 11. The slidable parts of the inner roller columns 11 are fixed by the same connecting plate 15. After the position adjusting member 14 passes through the end cover 13, its smooth end is rotatably connected to the end cover 13, and its threaded end is threadedly connected to the connecting plate 15. The user drives the position adjusting member 14 to rotate by screwing the end portion located on the outer side of the end cover 13, so that the position adjusting member 14 can drive the part of the slide plate 12 fixed to the connecting plate 15 to move quantitatively relative to other slide plates 12, and this moving distance is controllable, thereby adjusting the degree of staggering of needles on different slide plates 12.

[0045] The adjusting member 14 is a bolt.

[0046] Preferably, the slide plates 12 of the slidable part are aligned with each other; and the slide plates 12 of the fixed part are aligned with each other.

[0047] Preferably, the slide plates 12 of the slidable part are arranged in a staggered manner, and the slide plates 12 of the fixed part are arranged in a staggered manner.

[0048] Example 3

[0049] like Figure 3The roller 1 includes an inner roller column 11, a slide plate 12, an end cover 13, an electromagnetic block 141, a magnetic sheet 142 and a connecting plate 15. The inner roller column 11 is a hollow cylinder with an opening at one end. The end cover 13 is connected to the inner roller column 11 through a snap-fit ​​structure or a threaded structure, and can rotate synchronously with the inner roller column 11. Part of the slide plate 12 is slidably connected to the inner roller column 11, and the other part of the slide plate 12 is fixed to the inner roller column 11. The slidable parts of the inner roller columns 11 are fixed by the same connecting plate 15. The electromagnetic block 141 is detachably connected to the end cover 13 through a snap-fit ​​structure or a threaded structure, and the wire dragged by the electromagnetic block 141 is used to be electrically connected to the mains. When the electromagnetic sheet at the end of the electromagnetic block 141 is energized to generate magnetism, the magnetic sheet bonded to the connecting plate 15 and the electromagnetic block 141 have a magnetic attraction or magnetic repulsion effect, thereby driving the partially slidable slide plate 12 to move.

[0050] Another implementation method of this embodiment is to design all the slides 12 to be slidable, each slide 12 is connected to a corresponding connecting plate 15, the magnetic sheet 142 is fixed on the corresponding connecting plate 15, the magnetism generated by the electromagnetic block 141 after power is turned on is certain, that is, positive or negative, the magnetic sheet 142 is divided into a plurality of pole pieces, the pole pieces are either positive or negative, and the plurality of pole pieces are arranged alternately according to the difference in magnetic properties, and a magnetic force is generated between the electromagnetic block 141, thereby driving all the slides 12 to adjust their positions relative to the inner roller 11.

[0051] The magnetic force selection standard in this embodiment is: the slide plate 12 is driven by magnetic force to slide to the end of the sliding range to stably control the position of the slide plate 12. If the magnetic force is small, the piercing roller 1 may accidentally move and drag the single layer when piercing, causing the pores on the single layer to accidentally become larger.

[0052] Example 4

[0053] like Figure 4 and Figure 5 The roller 1 includes an inner roller column 11, a slide plate 12 and a position adjusting member 14. The inner roller column 11 is a hollow structure. Several slide plates 12 are slidably connected to the outer side wall of the inner roller column 11. The position adjusting member 14 is connected to the frame 2.

[0054] The position adjusting member 14 is a turntable fixed on the frame 2, on which are arranged wave-shaped protrusions of different heights. Whenever the slide plate 12 contacts the corresponding protrusion, it will be squeezed and slide to give way to the protrusion on the position adjusting member 14, thereby changing the position of the holes in which several slide plates 12 are pierced on the single layer.

[0055] Another implementation of this embodiment is that the position adjustment member 14 is a turntable, and the turntable is not fixed but rotatably connected to the frame 2. The position adjustment member 14 can be driven to rotate by an independent driving device, or can be driven by a motor linked to the inner roller 11 through a transmission assembly. Since the driving method is common, it will not be repeated. The rotation between the position adjustment member 14 and the slide plate 12 follows the following rules:

[0056] The definition is as follows:

[0057] t: time (s)

[0058] Angular velocity of position adjustment member 14 (rad / s)

[0059] A: Maximum displacement of the slide plate (12), here defined as A = 0.01m

[0060] n: the number of wave-shaped protrusions on the position adjustment member 14 (pieces)

[0061] m: the number of slide plates on the inner roller 11 (pieces)

[0062] θ0: Angular position of the first protrusion on the position adjustment member 14 reaching the surface S (rad)

[0063] φ0: Initial angular position of the first slide plate 12 on the inner roller 11 relative to the surface S (rad)

[0064] The following rules apply:

[0065]

[0066] On this basis, the frame 2 can be fixed or rotatably connected to the squeezing roller, and the surface of the squeezing roller is coated with a tough film. When the puncture needle pokes the film, the film will not be punctured, and the film will be reset after the puncture needle leaves.

[0067] The material of the membrane can be selected from silicone rubber, thermoplastic polyurethane or polyurethane.

[0068] The slide plate 12 includes an outer plate 121 and an inner plate 122. The outer plate 121 is slidably connected to the inner roller 11. The inner plate 122 is elastically slidably connected to the outer plate 121. The needle penetrates one side of the outer plate 121 and is fixedly connected to the inner plate 122.

[0069] In addition, there is a virtual surface S between the frame 2 and the tying roller 1, which is tangent to the frame 2 and the tying roller 1. The single-layer L segment input by the unwinding wheel 4 on one side of the frame 2 passes through the piercing holes of the tying needles on the tying roller 1 and is synchronously squeezed and moved to the surface S by the tying roller 1 and the frame 2. After that, after the L segment leaves the surface S, because the output angle is large enough, the tying needles are retracted in the internal space of the outer layer plate 121. Therefore, it can be avoided that the tying needles damage the single-layer gaps when the single layer leaves the surface of the slide plate 12.

[0070] Working principle of the present invention:

[0071] The present invention studies several ways of adjusting the needle layout positions, so that the needle roller 1 that rotates with the movement of the single layer can pierce non-matrix holes on the surface of the single layer, making the layout positions of the holes of each single layer more diverse. After the single layers produced in this way are consolidated together, their filtering effect is better.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
