Technical Field
[0001] This utility model relates to the field of needle punching machine technology, and in particular to a needle punching machine for high-thickness needle punching cotton. Background Technology
[0002] A needle-punching machine is a type of machinery used in textile processing, primarily for the production of nonwoven fabrics. It reinforces the fiber web through needle punching, giving it a certain strength and stability.
[0003] The main working principle of a needle punching machine is to repeatedly puncture a fiber web using a needle plate with hooks. During the needle punching process, the hooks hook and pull some fibers into the fiber web, causing the fibers to become entangled and interwoven, forming a nonwoven fabric with a certain strength and stability. For example, Chinese Patent Publication No. CN217104277U provides a needle punching machine for high-thickness needle-punched cotton, belonging to the field of textile equipment technology. It includes: a needle plate, needles, and a perforated plate; the top of the needle plate is connected to the needle punching machine drive mechanism via a connecting component; the needles are fixedly mounted on the bottom surface of the needle plate; and the perforated plate is connected via a connecting mechanism. The connecting mechanism is fixedly connected below the needle plate; the needles are evenly distributed in the middle of the bottom surface of the needle plate, with a reserved area at the edge for the connecting mechanism; the connecting mechanism includes a telescopic rod and an elastic element; the telescopic rod is located at the four corners of the needle plate, one end of which is fixedly connected to the bottom surface of the needle plate, and the other end of which is fixedly connected to the top surface of the needle plate; the elastic element is located along the side of the needle plate, one end of which is fixedly connected to the bottom surface of the needle plate, and the other end of which is fixedly connected to the top surface of the needle plate; the needle plate has needle holes corresponding to the needles. This invention reduces the probability of needle breakage through the action of the needle plate.
[0004] Currently, in order to process thick needle-punched cotton, it is necessary to ensure that the needle punching machine can easily adjust the rolling process according to the thickness of the needle-punched cotton during the overall feeding process. This ensures that the overall needle-punched cotton material can be rolled stably during feeding, while also having a certain tension effect, thus ensuring the stability of the needle punching machine in processing thick needle-punched cotton.

[0018] 1. When needing to needle-punch a thick needle-punched cotton bollard, the bollard is fed in from one side of the table and out from the other. The bollard passes between guide roller 1 and guide roller 2 at any position, and simultaneously passes above the push rod and below the needle, achieving stable conveying of the bollard. The piston rod 2 of cylinder 2 is pushed forward, causing the piston rod 2 to drive the guide roller 2 on the moving frame to move downward. Depending on the thickness of the bollard, it can be combined with guide roller 1 for roller pressing and conveying. Through the setting of the push rod, and the push rod sliding on the column through the sleeve, combined with the compression and reset effect of spring 2, the push rod can tension the bollard as it passes through, ensuring the fabric tightness during the needle-punching process.
[0019] 2. During needle punching, the piston rod of cylinder one extends and retracts, causing the piston rod to move the needle of the needle punching structure up and down, ensuring stable contact with the overall cotton material. Driven by the motor, the rotating shaft drives the shaft rod, which in turn allows the cam to rotate stably. The cam's high and low positions continuously contact the needle plate, and the connecting rod slides within the sleeve, allowing the needle plate to move up and down. The spring's reset effect ensures that the needle plate drives the needle to move up and down stably, achieving reciprocating needle punching of the entire needle-punched cotton fabric.

The surface of the shaft 1002 is interference-fitted with the inner ring wall of the bearing 1001. When the needle-punched cotton fabric is conveyed, a feeding roller and a receiving roller are used to assist at both ends of the cotton material to ensure the stability of the driving conveying of the needle-punched cotton during processing and to give it sufficient feeding force.
[0030] It should be further explained that a cam 1004 is provided on the surface of shaft 1002. The connection between cam 1004 and shaft 1002 is fixed by screws. The surface of cam 1004 is always in close contact with the upper end of needle plate 17. A motor 1003 is provided at one end of shaft 1002. The outer wall of motor 1003 is fixedly assembled with the inner side of support frame 13 by bracket. The lower end of motor 1003 does not contact the surface of needle plate 17.

[0031] It should be further explained that a side plate 2 is provided above the tabletop 1. The lower end of the side plate 2 is fixed to the surface of the tabletop 1 by screws. A bearing 23 is provided through the surface of the side plate 2. The connection between the bearing 23 and the side plate 2 is fixed by welding. The same shaft 22 is provided through the interior of the two bearings 23. The surface of the shaft 22 is interference-fitted with the inner ring wall of the bearing 23. A guide roller 24 is fixedly sleeved on the surface of the shaft 22.

[0032] It should be further explained that a positioning frame 21 is erected on the upper end of the side plates 2 distributed along both sides. The connection between the positioning frame 21 and the side plate 2 is fixed by screws. A cylinder 29 is installed through the upper end of the positioning frame 21. The connection between the cylinder 29 and the positioning frame 21 is fixed by screws. A piston rod 2 is installed inside the cylinder 29.

[0033] It should be further explained that bearings 27 are respectively installed on both sides of the movable frame 25. The connection between the bearings 27 and the movable frame 25 is fixed by welding. The same shaft 26 is installed inside the two bearings 27. The surface of the shaft 26 is interference-fitted with the inner ring wall of the bearing 27. The guide roller 28 is fixedly sleeved on the surface of the shaft 26.
[0034] It should be further explained that a column 3 is also provided above the tabletop 1. The lower end of the column 3 is fixedly assembled with the surface of the tabletop 1. A sleeve 31 is slidably sleeved on the surface of the column 3. A spring 32 is wound around the surface of the column 3. The two ends of the spring 32 are fixedly assembled with the end face of the sleeve 31 and the surface of the tabletop 1, respectively.
[0035] It should be further explained that there are several sleeves 31 along the longitudinal position of the platform 1. The upper end of the multiple sleeves 31 in the same longitudinal row is fixed with a push rod 33 for tensioning. Through the reset effect of the spring 32, the cotton material passing through the push rod 33 can be lifted upward, thereby playing an auxiliary tensioning effect. The guide roller structure consists of four rollers, which are arranged in pairs and distributed along both sides of the support frame 11. The push rod 33 is set between any two guide roller structures in any one of the pairs.
[0036] Working method: When needing to needle-punch a thick needle-punched cotton bollard, the bollard is fed in from one side of the table 1 and out from the other side. The bollard passes between guide roller 1 24 and guide roller 28 at any position, and simultaneously passes above push rod 33 and below needle 18, achieving stable conveying of the bollard. The piston rod 2 of cylinder 29 is pushed forward, causing the piston rod 2 to drive guide roller 28 on the moving frame 25 to move downward. Depending on the thickness of the bollard, it can be combined with guide roller 1 24 for roller pressing and conveying. Through the setting of push rod 33, and the sliding of push rod 33 on column 3 through sleeve 31, combined with the compression and reset effect of spring 2 32, push rod 33 can tension the bollard passing through, ensuring the fabric tightness during the needle-punching process.
[0037] During needle punching, the piston rod of cylinder 12 extends and retracts, causing the piston rod to move the needle 18 of the needle punch structure up and down, ensuring stable contact with the overall cotton material. Driven by motor 1003, the rotating shaft drives shaft 1002, thereby enabling cam 1004 to rotate stably. The cam 1004 continuously contacts the needle plate 17 through its high and low positions, and the connecting rod 15 slides within the sleeve 14, allowing the needle plate 17 to move up and down. The reset effect of spring 16 ensures that the needle plate 17 can drive the needle 18 to move up and down stably, realizing the reciprocating needle punching process on the entire needle punched cotton fabric.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
