Description

Technical Field

[0001] The invention relates to the technical field of flocking nonwoven fabric manufacturing, in particular to a needle punching device used for nonwoven fabric manufacturing. Background Art

[0002] The non-woven needle punching device, also known as the non-woven needle punching machine, is a device designed specifically for the production of non-woven fabrics. It interweaves the fibers between the fiber layers through high-speed needle punching to form an organic overall structure.

[0003] In the production process of non-woven fabrics, when the needle density is high, that is, the number of needles per unit area is large, the interlacing points between fibers increase, and the fibers are more tightly bonded. This helps to improve the breaking strength and elongation at break of the non-woven fabric, making it tougher and more durable. However, too high acupuncture density may also cause the non-woven fabric to be too stiff, affecting the feel and comfort. On the contrary, when the needle density is low, the interlacing points between fibers are reduced, and the non-woven fabric may be softer and more fluffi, but the corresponding strength and durability will be reduced.

[0004] However, the existing non-woven fabric needling device cannot quickly adjust and replace the needle density during needling according to needs, and cannot quickly perform needling production on different non-woven fabrics according to needs, and is not convenient to use.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] The embodiment of the present invention provides a needle punching device for nonwoven fabric manufacturing, such as Figure 1 As shown, it includes a frame 1 and a mounting plate 4. A lifting seat 3 is arranged on the left and right sides of the mounting plate 4. The bottom of the lifting seat 3 is fixedly connected with an electric telescopic rod 2. The bottom end of the electric telescopic rod 2 is fixedly connected to the frame 1. The upper and lower surfaces of the mounting plate 4 are respectively fixedly connected with a first needle 6 and a second needle 5.

The second rotating shaft 18 is rotatably connected to the fixing seat 8. The fixing seat 8 is provided with a second flipping assembly for driving the connecting plate 9 to flip. During operation, the mounting plate 4 reciprocates up and down through the electric telescopic rod 2. The second needles 5 under the mounting plate 4 perform needle punching on the non-woven fabric. The first needles 6 above the mounting plate 4 are continuously inserted into the cleaning holes of the first cleaning block 10 to push the thread on the first needle 6 to the root of the first needle 6.

[0037] By setting the cleaning mechanism, the needles below the mounting plate 4 can be cleaned by the up and down reciprocating motion of the mounting plate 4 during operation while the needles below the mounting plate 4 are working, which is convenient for use after the next switch.

[0038] The shape of the connecting plate 9 is completely the same as that of the mounting plate 4 , the thickness of the first cleaning block 10 and the second cleaning block 11 are the same, and the thickness of the first cleaning block 10 is not less than the length of the first needle 6 .

[0039] The first cleaning block 10 and the second cleaning block 11 are made of the same material, and the material of the first cleaning block 10 is set to rubber.

[0040] The second flip assembly includes a second motor 19, a third bevel gear 20, and a fourth bevel gear 21. The second motor 19 is fixedly connected to the fixed seat 8.

The third bevel gear 20 and the fourth bevel gear 21 are meshed with each other. The single-chip computer 7 is electrically connected to the second motor 19.

[0041] like Figure 6-7 As shown, it also includes an automatic adjustment mechanism for automatically adjusting the orientation of the first cleaning block 10 and the second cleaning block 11, the automatic adjustment mechanism includes a laser emitter 17, a laser receiver 23, a first connecting shaft 16, a second connecting shaft 22, and four reflective triangle blocks 24.

When the laser transmitter 17 emits laser toward directly below, under the action of the four reflective triangle blocks 24, the laser will be reflected and shot down from directly above the laser receiver 23. When the laser receiver 23 does not receive the laser, the single-chip microcomputer 7 controls the second motor 19 to drive the second rotating shaft 18 to rotate, and the second rotating shaft 18 drives the laser receiver 23 to rotate until the laser receiver 23 corresponds to the laser generated by the laser transmitter 17, and the laser receiver 23 generates a signal. After receiving the signal, the single-chip microcomputer 7 controls the second motor 19 to stop. At this time, the needle on the top of the mounting plate 4 and the cleaning block at the bottom of the connecting plate 9 match each other.

[0042] Through the setting of the automatic adjustment mechanism, the orientation of the connecting plate 9 can be automatically adjusted according to the orientation of the mounting plate 4 to ensure that the cleaning block below the connecting plate 9 corresponds to the needle above the mounting plate 4. The needle above the mounting plate 4 does not correspond to the cleaning block below the connecting plate 9, which causes the needle above the mounting plate 4 to directly pierce the cleaning block and cause the mounting plate 4 to get stuck. It is very convenient to use.

[0043] Working principle: by setting the mounting plate 4, the first needle 6 and the second needle 5, and switching the downward side of the mounting plate 4 through the first flip assembly, it is possible to choose to use the first needle 6 or the second needle 5 with different densities to perform acupuncture on the non-woven fabric, so that the density of the needle can be quickly adjusted as needed, which is used for processing non-woven fabrics with different properties, and the use effect is good.
