Abstract
Description
Technical Field
[0001] This utility model relates to the field of nonwoven fabric production technology, specifically to a slitting machine for nonwoven fabric production. Background Technology
[0002] In the production of nonwoven fabrics, the slitting process is crucial, as it directly affects product quality and production efficiency. With the continuous expansion of the application fields of nonwoven fabrics, the market has put forward higher requirements for the cutting precision and efficiency of nonwoven fabrics. In order to meet this demand, various slitting machines for nonwoven fabric production have emerged.
[0003] For example, a Chinese patent proposes a slitting machine for nonwoven fabric production, patent publication number CN217517237U. The slitting machine in this patent uses a motor to drive a lead screw, which in turn moves the cutting blade to cut the nonwoven fabric. This design improves cutting efficiency to some extent and allows control of the cutting width by adjusting the motor speed and the lead screw stroke. However, the above patent only solves the problem of cutting efficiency and basic cutting width adjustment, without fully considering the stability of the cutting process and further improvement of cutting accuracy. In actual use, the cutting blade may be affected by external factors during movement, such as material inhomogeneity and equipment vibration, leading to increased cutting errors and affecting the cutting quality of the product.
[0004] In addition, the above-mentioned patent also has certain limitations in adjusting the cutting blade angle. Although the movement trajectory of the cutting blade can be changed by adjusting the parameters of the motor, this method usually needs to be carried out in a stopped state, and the adjustment process is cumbersome and not conducive to quickly adapting to the cutting needs of non-woven fabrics of different widths. At the same time, due to the lack of necessary buffering and stabilization mechanisms during the adjustment process, the impact and vibration that may be generated during the adjustment process will further affect the cutting accuracy. Therefore, we propose a slitting machine for non-woven fabric production. Utility Model Content

[0052] Working principle: The nonwoven fabric is placed on the unwinding roller 4 and guided by the guide roller 5, it moves to the position of the slitting knife 9 along a predetermined path. After the equipment is started, the nonwoven fabric is continuously conveyed to the slitting knife 9 under the rotation of the unwinding roller 4. The clamping ring 8 clamps the fixing posts 7 on both sides, and the circular hole above the clamping ring 8 corresponds to the adjusting rod. The bolts are installed to fix the clamping ring 8, and the adjusting rod 10 is clamped above the clamping ring 8. If it is necessary to adjust the angle of the slitting knife 9, the cylinder 19 is first started. The piston rod of the cylinder 19 extends, driving the positioning frame 17 to move in the moving groove of the second adjusting frame 20. The movement of the positioning frame 17 will cause the relative position of the locking block 15 and its semi-circular groove with the adjusting rod 10 to change, thereby... By changing the tilt angle of the slitting blade 9, the locking block 15 engages with the arc groove 18 on the surface of the second adjustment frame 20 to fix the adjustment rod 10 and prevent misalignment. The buffer spring 16 acts as a buffer during the movement of the positioning frame 17, allowing the adjustment rod 10 to move along the trajectory of the arc groove 18, while ensuring a smooth and impact-free adjustment process. When the angle of the slitting blade 9 is adjusted to the required position, the nonwoven fabric is precisely cut to the required width by the slitting blade 9 during the conveying process. When the adjustment rod 10 wears out, the motor 14 is controlled to drive the threaded tube 13 to rotate. The threaded tube 13 drives the first adjustment frame 11 to move outward through the connecting block 12, thereby removing and replacing the adjustment rod 10.
