[0002] The needle loom is a device that compacts and needles the fiber blanket into finished products. It uses needles with different shapes and barbed hooks to repeatedly puncture the fiber web. When the needles penetrate the fiber web, they drive the fibers on the surface and sub-surface of the fiber web to move vertically, causing the fibers to shift, thereby squeezing the fiber web to a certain extent, causing the fibers in the fiber web to be closer and compressed.

[0003] Non-woven fabrics need to be kept in a tensioned state during the production process. The existing tensioning measures are to convey the non-woven fabrics along multiple guide rollers and keep the non-woven fabrics in a tensioned state by adjusting the positions of the guide rollers. However, in the process of the guide rollers conveying the non-woven fabrics, there is a problem of non-woven fabrics being offset, which affects the accurate transmission of the non-woven fabrics, and therefore needs to be improved.

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] See also Figure 1-Figure 5 A tensioning device for a non-woven fabric needle-punching machine comprises a base 1; mounting plates 2 are installed on both sides of the base 1, symmetrically distributed transmission shafts 3 are rotatably installed on the mounting plates 2, and transmission rollers 4 are installed on the transmission shafts 3. Adjustment components are installed on both sides of the middle of the base 1, and an adjustment plate 5 is installed at one end of the adjustment component away from the base 1, a rotating shaft 6 is rotatably provided on the adjustment plate 5, a rotating drum 7 is installed on the rotating shaft 6, and an annularly distributed offset component is installed on the outer side of the rotating drum 7, the offset component is connected to a driving component, the adjusting component is used to adjust the position of the offset component for tensioning the non-woven fabric, the offset component is used to correct the offset of the non-woven fabric, and the driving component is used to drive the offset component.

[0021] The tension of the transmitted nonwoven fabric can be adjusted by the provided adjusting component, and when the nonwoven fabric is offset, the offset component can be driven by the driving component to correct the position of the nonwoven fabric, thereby avoiding affecting the accurate transmission of the nonwoven fabric.

[0022] In one case of this embodiment, a second motor 22 connected to the conveying shaft 3 is installed on the mounting plate 2. By starting the second motor 22, the conveying shaft 3 connected thereto is driven to rotate, thereby driving the conveying roller 4 to rotate, so that the non-woven fabric is conveyed.

[0023] In one case of the present embodiment, the offset component includes a bracket 8 installed at both ends of the rotating drum 7 and distributed in a ring shape, and a symmetrically distributed fixed frame 9 is installed on the bracket 8, and a power shaft 10 is rotatably installed on the fixed frame 9, and a transmission wheel 11 is installed on the power shaft 10. The transmission wheels 11 at both ends of the rotating drum 7 are connected by a conveyor belt 12. When the non-woven fabric is offset, the power shaft 10 connected thereto can be driven by the driving component. The power shaft 10 will drive the transmission wheel 11 to rotate, and then drive the conveyor belt 12 for transmission, thereby correcting the offset non-woven fabric back to the correct position, thereby avoiding the offset affecting the accurate transmission of the non-woven fabric.

[0024] In one case of this embodiment, the driving component includes connecting bevel gears 13 installed at both ends of the power shaft 10, and adjacent connecting bevel gears 13 are meshed with each other. A first motor 15 is installed on one of the fixed frames 9, and a second transmission wheel 16 is installed at the driving end of the first motor 15. A first transmission wheel 14 is installed on one of the power shafts 10, and the first transmission wheel 14 and the second transmission wheel 16 are connected by a synchronous belt 17.

A spring 21 connected to the slider 20 is arranged in the fixed cylinder 18. During the transmission of the non-woven fabric, under the action of the spring 21, the slider 20 is subjected to an upward elastic force, so that the movable rod 19 will elastically support the adjusting plate 5, so that the non-woven fabric continues to contact with the conveyor belt 12, and pressure is applied to the non-woven fabric, so that the non-woven fabric is subjected to appropriate tension.

[0026] The working principle of the utility model is as follows: when in use, the non-woven fabric passes around the conveying roller 4 on the left, the conveying belt 12 in the middle, and the conveying roller 4 on the right in turn, so that the non-woven fabric contacts the multiple conveying belts 12 in the middle, and by starting the second motor 22, the conveying shaft 3 connected thereto is driven to rotate, thereby driving the conveying roller 4 to rotate, so that the non-woven fabric is conveyed. When the non-woven fabric is conveyed, the contact between the non-woven fabric and the conveying belt 12 will also cause the rotating drum 7 to rotate, and in the process of conveying the non-woven fabric, under the action of the spring 21, the slider 20 is subjected to an upward elastic force, so that the movable rod 19 will elastically support the adjusting plate 5, so that The non-woven fabric is kept in contact with the conveyor belt 12, and pressure is applied to the non-woven fabric, so that the non-woven fabric is subjected to appropriate tension. When the non-woven fabric is offset, the first motor 15 can be started to drive the power shaft 10 connected thereto through the first transmission wheel 14, the second transmission wheel 16 and the synchronous belt 17. The power shaft 10 will drive the transmission wheel 11 to rotate, and then drive the conveyor belt 12 for transmission, and the meshing connecting bevel gear 13 will simultaneously drive the remaining power shafts 10 to rotate, so that multiple conveyor belts 12 are transmitted synchronously, and then the offset non-woven fabric is corrected back to the correct position, thereby avoiding the offset affecting the accurate transmission of the non-woven fabric.

[0027] The utility model provides a tensioning device for a non-woven fabric needle-punching machine, which can adjust the tensioning force of the transmitted non-woven fabric by means of an adjusting component, and when the non-woven fabric is offset, the offset component can be driven by a driving component to correct the position of the non-woven fabric, thereby avoiding affecting the accurate transmission of the non-woven fabric.
