Description

Technical Field

[0001] This utility model belongs to the technical field of nonwoven fabric slitting machines, and specifically relates to a nonwoven fabric slitting machine. Background Technology

[0002] A nonwoven fabric slitting machine is a mechanical device that cuts wide nonwoven fabrics, paper, mica tape, or film into multiple narrow strips. It is mainly used in the slitting process of nonwoven fabrics, mica tape, paper, insulating materials, and films. Currently, common nonwoven fabric slitting machines mainly consist of a frame, a winding section, an unwinding section, a cutting section, and guide rollers. In actual application, the unwinding section unwinds the nonwoven fabric to be slitting, the cutting section cuts the unwound nonwoven fabric, and the winding section winds up the slitting nonwoven fabric, thus completing the nonwoven fabric slitting process.

[0003] Most existing nonwoven fabric slitting machines adjust the slitting distance of nonwoven fabrics by adjusting the overall spacing of the cutters. They generally cannot independently adjust the positions of multiple cutters, nor can they slitting nonwoven fabrics with different spacings. This greatly limits the use of nonwoven fabric slitting machines. At the same time, the cutter positions do not have a slitting limit function, and cannot limit the slitting of the nonwoven fabric to be slitted. This makes it easy for uneven slitting surfaces to occur when slitting nonwoven fabrics, resulting in poor flexibility and slitting stability of the nonwoven fabric slitting machine.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a nonwoven fabric slitting machine.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0059] Simultaneously, the position of the tension limiting block 304 can be adjusted by controlling the movement of the clamping limiting post 312 within the sliding clearance groove of the tension limiting block 304, thereby facilitating the control of the tension limiting state of the tension limiting block 304 on the nonwoven fabric. Subsequently, the slitting blade 303 can be rotated by controlling the operation of the slitting motor 311, thereby slitting the nonwoven fabric through the rotating slitting blade 303. Furthermore, during use, the extension and retraction of the cylinder piston rod 308 can be controlled by controlling the supply of compressed air to the control cylinder 307, thereby facilitating real-time adjustment of the slitting position of the slitting blade 303.
