DETAILED DESCRIPTION

[0022] The preferred solution is Figures 1 to 5 As shown, a multi-fold non-woven fabric slitting mechanism includes a slide 10 arranged at the outlet of a negative pressure rotating sheet taking device 9, on which a side material vertical cutting device 11 and an intermediate vertical cutting device 12 are installed. The side material vertical cutting device 11 and the intermediate vertical cutting device 12 are arranged in sequence along the conveying direction of the multi-fold non-woven fabric.

[0023] The negative pressure rotary film taking device 9 is a component of a high-speed angle cloth folding machine device, which includes an unwinding roller. The gauze on the unwinding roller passes through a tension roller group, a first combing mechanism, a deviation correction device, a reversing folding mechanism, a second combing mechanism, a traction device, a secondary folding and cutting device, and a negative pressure rotary film taking device in sequence. The unwinding roller is driven to rotate by an active unwinding drive device. The high-speed angle cloth folding machine device is used to fold a single layer of non-woven fabric into two layers, and then fold the two layers of non-woven fabric into four layers (the folding effect of the four layers of non-woven fabric is as follows Figure 5 As shown, each line represents a layer of non-woven fabric), and finally cut into four layers of non-woven fabric sheets of about 50 cm. The plane where the four layers of non-woven fabric sheets are located is perpendicular to the bottom surface of the chute 10, and a plurality of four layers of non-woven fabric sheets are squeezed together.

[0024] The four-layer nonwoven fabric sheets are not transported by a transport belt, but slide on a slide chute 10 , and the driving force comes from the squeezing force of the outlet of the negative pressure rotating film taking device 9 , and a plurality of four-layer nonwoven fabric sheets move slowly in the slide chute 10 .

[0025] Example 1: The edge material vertical cutting device 11 is used to cut off two edge materials of four-layer non-woven fabric, and the four-layer non-woven fabric is further cut into four groups by the middle vertical cutting device 12. The non-woven fabric after cutting is equivalent to eight groups of two-layer non-woven fabric.

[0026] The middle vertical cutting device 12 in this embodiment is provided with three vertical cutting blades. For example, the high-speed angle cloth folding machine device produces four-layer non-woven fabric with a length of 50 cm. If the customer needs two-layer non-woven fabric with a length of 10 cm, the edge material vertical cutting device 11 is used to cut off 5 cm of edge material respectively, and then the middle vertical cutting device 12 is used to cut the four-layer non-woven fabric with a length of 40 cm into 4 groups, which is equivalent to preparing eight groups of two-layer non-woven fabrics with a length of 10 cm.

[0027] Example 2: If the customer needs multiple groups of 3-layer non-woven fabrics, a folding plate can be added between the first comb mechanism 3 and the correcting device 4. The folding principle of the folding plate is similar to that of the reversing folding mechanism 5. In this way, one layer of non-woven fabric can be folded into three layers of non-woven fabric. Finally, after cutting by this device, eight groups of 10 cm three-layer non-woven fabrics can be made.

[0028] By analogy, nonwoven fabrics with other numbers of layers can be prepared.

[0029] Furthermore, the slide slot 10 comprises a concave slot 10.1, and wing plates 10.2 are connected to both sides of the concave slot 10.1. The wing plates 10.2 are provided with strip-shaped fixing holes 10.3; the wing plates 10.2 are used to be placed on the frame and fixed by locking bolts 10.4.

[0030] The slide groove 10 is made of stainless steel, and the surface of the slide groove 10 is smooth, which is conducive to the non-woven fabric sliding on the slide groove 10. The slide groove 10 is used to provide a sliding channel for the non-woven fabric sheet.

[0031] Furthermore, the edge material vertical cutting device 11 comprises two vertical cutting blades 11.4, and the two vertical cutting blades 11.4 are used to cut the edge material of the multi-fold non-woven fabric;

[0032] The edge material vertical cutting device 11 also includes a pressing plate 11.1, which is connected to the cutting machine housing 11.3 through a hanger 11.2.

[0033] The edge material vertical cutting device 11 and the middle vertical cutting device 12 are electric cutting devices, and the vertical cutting blade 11.4 is used to reciprocate up and down to cut the non-woven fabric. The edge material vertical cutting device 11 and the middle vertical cutting device 12 use existing cutting equipment, and the edge material vertical cutting device 11 and the middle vertical cutting device 12 use separate brackets as support. The utility model does not involve improvements to the cutting equipment. Specifically, there is no improvement in the working mode of the vertical cutting blade 11.4. On the basis of the existing cutting equipment, a pressing plate 11.1 and a hanger 11.2 are added, and the pressing plate 11.1 has a hole for the vertical cutting blade 11.4 to move.

[0034] Furthermore, the cutting principle of the middle vertical cutting device 12 is the same as that of the edge material vertical cutting device 11, except that the middle vertical cutting device 12 is provided with three vertical cutting blades 11.4, and the three vertical cutting blades 11.4 are distributed in a triangle.

[0035] Furthermore, a wedge-shaped guide block 13 is provided at the tail end of the chute 10, and the wedge-shaped guide block 13 is used to separate the adjacent multi-fold non-woven fabrics. The wedge-shaped guide block 13 is used to separate multiple groups of multi-fold non-woven fabrics to facilitate the staff to pack.

[0036] Furthermore, a scrap recovery device 14 is provided at the vertical cutting blade 11.4 of the scrap vertical cutting device 11. The scrap recovery device 14 includes a suction pipe, a suction fan and a scrap recovery box. The suction pipe is used to recover the cut scraps. Scrape recovery device: After the scraps on both sides are cut by the scrap vertical cutting knife, the two blowing pipes above and behind the scrap vertical cutting knife blow the cut scraps to the suction pipe port, and then the suction fan sucks the scraps into the scrap recovery box.
