Description
TECHNICAL FIELD
[0001] The utility model belongs to non - woven fabric processing equipment technical field, especially related to a non - woven fabric slitting mechanism for wet tissue processing. BACKGROUND
[0002] In the processing of wet tissue, the slitting process of non - woven fabric is a crucial link, which directly affects the size accuracy and production efficiency of the final product. The traditional non - woven fabric slitting method usually adopts fixed cutter or manually adjusted slitting component, and completes slitting through mechanical transmission and manual cooperation.
[0003] However, in actual production, large roll non - woven fabric often appears skewing in the slitting process, that is, the slitting knife cannot cut along the predetermined straight trajectory, resulting in the problem of slitting deviation and uneven size. This not only affects the product quality, but also may cause the subsequent processing procedure to be unable to proceed smoothly, increasing the scrap rate and production cost. The main reason for slitting skewing is that non - woven fabric is prone to uneven tension deviation during stretching and conveying. Because the width of large roll non - woven fabric is large, if uniform tension distribution cannot be maintained during unwinding, the fabric may deviate to one side during conveying, so that the slitting knife cannot cut accurately at the predetermined position. In addition, the traditional slitting component usually adopts fixed cutter, and the cutting trajectory of the cutter is difficult to adjust according to the actual position of the non - woven fabric. Once the fabric deviates, the slitting knife cannot maintain straight cutting, resulting in decreased slitting accuracy. In addition, some slitting equipment adopts single fixed cutter, and the other side relies on the natural alignment of fabric tension, but due to the flexible nature of non - woven fabric, its edge is prone to irregular deformation, making it difficult to maintain a straight cutting line, ultimately leading to increased slitting size error.

In this embodiment, the slitting component 3 is mainly composed of a gate-shaped slitting frame 31 that is longitudinally arranged across the front end of the table 11. The side of the slitting frame 31 is attached with a translation rail 32 of equal length. A translation seat 331 is embedded in the translation rail 32. The translation seat 331 is connected to the slitting cylinder 332 and can move in real time with the movement of the locking seat 39, so that the slitting blade 33 remains stable during the cutting process.

[0037] Combination Figures 1-2 As shown, based on the above embodiments, this embodiment further provides the following:
[0038] In this embodiment, anti-deviation rods 26 are symmetrically arranged on the outer side of the transmission bar 21. They are the same length as the transmission bar 21. The anti-deviation rods 26 are inserted through the bottom of the anti-deviation seat 27 and can be used for instant directional correction as the anti-deviation seat 27 moves longitudinally.
[0039] A shock-absorbing spring 28 is provided between the fork 24 and the positioning frame 23, which can move the positioning component 25 in a shock-absorbing and displaced manner as the positioning frame 23 moves longitudinally.
[0040] Please refer to the instruction manual appendix. Figures 1-2 This utility model provides a first embodiment of a nonwoven fabric slitting component 3 for wet tissue processing. In this embodiment, the slitting component 3 is mainly composed of a transmission bar 21 disposed on the outer side of the table 11. Anti-deviation rods 26 are symmetrically arranged on the outer side of the transmission bar 21. The anti-deviation rods 26 are the same length as the transmission bar 21 and pass through the bottom of the anti-deviation seat 27. The anti-deviation rods 26 can move longitudinally with the anti-deviation seat 27, so that the nonwoven fabric can be corrected in real time during the conveying process, ensuring that the fabric maintains a stable running trajectory before slitting.
[0041] Preferably, to further enhance the stability of nonwoven fabric cutting, in this embodiment, a shock-absorbing spring 28 is provided between the fork 24 and the positioning frame 23. The shock-absorbing spring 28 can move longitudinally with the positioning frame 23, allowing the positioning member 25 to be displaced with shock absorption when locking the nonwoven fabric. The shock-absorbing spring 28 enables the positioning member 25 to buffer external force impacts when subjected to force, avoiding positioning deviations caused by changes in fabric tension and equipment vibration, while ensuring that the nonwoven fabric remains stable during the slitting process and improving slitting accuracy.
[0042] Working principle and usage process of this utility model:
[0043] When using this slitting component 3 for nonwoven fabric processing, firstly, a large roll of nonwoven fabric is installed onto the feeding roller 4, ensuring that the fabric can be smoothly unrolled. After unrolling, the nonwoven fabric is conveyed along the flat table 11 of the main frame 1, and passes sequentially through the alignment mechanism 2 and the slitting component 3. The transmission bar 21 in the alignment mechanism 2 is horizontally attached to the outside of the table 11, and the positioning wheel 22 coupled to it can move horizontally with the transmission bar 21 to adjust the cutting position of the fabric. The axis of the positioning wheel 22 is connected to the L-shaped anti-deviation seat 27, and the anti-deviation seat 27 is equipped with a positioning motor 29, which can drive the transmission wheel to run, so that the nonwoven fabric remains aligned during the conveying process. The positioning frame 23 is longitudinally connected between the anti-deviation seats 27, and the U-shaped fork 24 at its front end is equipped with multiple downwardly positioned positioning elements 25. The positioning elements 25 can slide down to lock the nonwoven fabric, keeping it stable before slitting.
[0044] When the nonwoven fabric enters the slitting component 3, the synchronous pulley 37 of the portal slitting frame 31 drives the transmission belt 36 to rotate longitudinally. The clamping seat 39 on the upper section of the transmission belt 36 moves accordingly, driving the slitting blade 33 attached to the outside. The slitting blade 33 is connected to the slitting seat 333 by a vertically arranged slitting cylinder 332, and completes the cutting through the rotatable slitting blade 334 during the downward movement. The side of the slitting frame 31 is attached with a translation rail 32 of equal length, and the translation seat 331 embedded on it is connected to the slitting cylinder 332, which can move with the clamping seat 39 to achieve secondary fixation of the slitting blade 33. Before slitting, the pressing cylinder 34 at the bottom of the slitting frame 31 outputs power to press down the pressure plate 35 to fix the nonwoven fabric, so as to ensure the straightness accuracy of the cutting.
[0045] In addition, anti-deviation rods 26 are symmetrically arranged on the outer side of the transmission bar 21. The anti-deviation rods 26 pass through the bottom of the anti-deviation seat 27 and can move longitudinally with the anti-deviation seat 27 to perform real-time directional correction of the nonwoven fabric. A shock-absorbing spring 28 is supported between the fork 24 and the positioning frame 23. The shock-absorbing spring 28 can move longitudinally with the positioning frame 23, so that the positioning component 25 has a shock-absorbing displacement function when locking the nonwoven fabric, reducing the impact of external forces. During the slitting process, the slitting blade 334 and the slitting seat 333 are connected by threads, which can be quickly changed according to the fabric to meet the processing requirements of different specifications.
[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
