Further, the first cutter 100 and the second cutter 200 of the present embodiment respectively and independently perform a periodic rotary slitting operation, and the blade distance between the first cutter 100 and the second cutter 200 is greater than the length of at least two finished product rolls b.

In this embodiment, the cutting knife 400 is used to cut the head end portion a1 and the tail end portion a2 of the source roll e in sequence, and the source roll e is cut to remove the head end portion a1 and the tail end portion a2 and then becomes the long roll a 3. The length of the long reel a3 after being cut by the cutting knife 400 is integral multiple of the length of the finished reel b, and then the long reel a3 after being cut by the cutting knife 400 is conveyed to the first cutting knife 100 along the paper conveying channel.

In the embodiment, the first cutter 100 is only used for sequentially cutting the long roll a3 conveyed along the paper feeding path into a plurality of roll segments a, that is, the long roll a3 is conveyed forward towards the first cutter 100, and the first cutter 100 is operated once to cut the long roll a3 into a roll segment a each time the first cutter 100 is conveyed to a rated length of the first cutter 100, and the first cutter 100 is repeatedly operated to cut the long roll a3 into a plurality of roll segments a in a segmented manner. The bobbin sections a obtained by cutting are sequentially conveyed forward towards the direction of the second cutter 200.

In this embodiment, the second cutter 200 is only used for half-cutting the paper strip segment a cut by the first cutter 100 into two required finished paper strips b, that is, each paper strip segment a is conveyed forward to the second cutter 200, and when each paper strip segment a is conveyed to the second cutter 200 by the rated length, the second cutter 200 acts to half-cut the paper strip segment a into two finished paper strips b, and the second cutter 200 repeats the action to half-cut each paper strip segment a into two finished paper strips b one by one. In addition, the finished strip b thus obtained is then sent to a predetermined downstream station.

For ease of understanding, the following further description is made in conjunction with specific working methods:

the working method of the continuous cutting and slitting system comprises the following steps:

referring to fig. 2 and 4, in step s1, the source roll e is conveyed to the cutting knife 400 along the paper conveying path, the front end of the source roll e is advanced to the rated cutting position of the cutting knife 400, the cutting knife 400 cuts the removed head end a1, then the removed head end a1 is conveyed forward to the first cutting knife 100 continuously until the tail end reaches the rated cutting position of the cutting knife 400, and the cutting knife 400 removes the tail end a2 to form a long roll a3, so that the length of the long roll a3 processed by the cutting knife 400 is integral multiple of the length of the required finished roll b.

Referring to fig. 3, in step s2, the source reel e with the head end portion a1 removed is continuously conveyed and moved forward, when the source reel e or the long reel a3 moves forward to exceed the rated length of the first cutter 100, the first cutter 100 acts to cut the source reel e or the long reel a3 to obtain a reel segment a, the first cutter 100 continuously repeats the cutting action to continuously cut the source reel e or the long reel a3 in sections, and the cut reel segments a are sequentially conveyed and moved forward towards the direction of the second cutter 200;

referring to fig. 4, in step s3, the roll segments a are conveyed forward one by one to the second cutter 200, wherein after each roll segment a is conveyed forward by half the length of the second cutter 200, the second cutter 200 acts to half-cut the roll segments a to obtain two required finished rolls b, the obtained finished rolls b are then sent out to a predetermined downstream station, and the second cutter 200 continuously repeats the cutting action to half-cut the roll segments a in sequence.

In addition, the case of the length of the long roll a3 after being processed by the cutting knife 400 may include the following cases:

the first condition is as follows: referring to fig. 3 and 5, when the length of the log a3 processed by the cutting knife 400 is double integral multiple of the length of the finished log b, the first cutting knife 100 performs a periodic cutting operation to cut the log a3 into a plurality of log segments a, and then each log segment a is conveyed to the second cutting knife 200 before being cut into two finished logs b, i.e., each log a3 is cut into a first and a last log portion by the first cutting knife 100, i.e., each log segment a is a log segment a.

Case two: referring to fig. 6, when the length of the log a3 processed by the cutting knife 400 is a single integral multiple of the length of the finished log b, the first cutting knife 100 first cuts out a finished log b (the finished log b is directly sent out towards the second cutting knife 200), the first cutting knife 100 then performs a periodic cutting action to cut the log a3 into a plurality of log segments a, and then each log segment a is moved to the second cutting knife 200 from the front of the conveyor to be cut into two finished logs b in half and sent out.

Case three: referring to fig. 7, when the length of the log a3 processed by the cutting knife 400 is a single integral multiple of the length of the finished log b, the first cutting knife 100 first separates a plurality of log segments a, and each log segment a is transported to the second cutting knife 200 to be cut into two half-finished logs b and then sent out, and the remaining portion to be cut into the tail end of the log a3 by the first cutting knife 100 is used as the finished log b (the finished log b is sent out directly towards the second cutting knife 200).

The steps are repeated circularly, continuous cutting and slitting processing is achieved, the cutting cutter 400 is adopted to cut and remove the head end portion a1 and the tail end portion a2 in advance, the first cutter 100 is adopted to cut a plurality of winding drum sections a (the length of the winding drum sections a is twice of that of the required finished winding drums b), and the second cutter 200 is adopted to cut the winding drum sections a one by one, so that the processing mode of the cutting and slitting system is optimized, and the slitting effect is improved.
