Because the coiled material is wider, two persons are required to carry out threading, the thickness of the coiled material is smaller in the threading process, the threading distance can be as long as more than ten meters, local deformation and even belt breakage are easy to occur due to uneven stress caused by pure manual pulling, and the threading process consumes long time and large consumption of pole pieces and has low working efficiency.

The present utility model provides a web cutting and conveying apparatus that alleviates or avoids the problems described above.

As shown in fig. 9, another aspect of the present utility model provides a slitting conveyor for a web, which includes a feed roller 1000, a collection roller 2000, a cutter roller 3000, and a web-receiving mechanism, which is the slitting conveyor provided by the present utility model, disposed between the feed roller 1000 and the collection roller 2000. The improvement of the present utility model is to optimize the threading of the web, as shown in fig. 8, where the threading is to pull the web through a long distance, through many intermediate parts, and thus is difficult when the web is wide. The idea of the utility model is to add a pre-cut threading process (realized by the device of fig. 1-7) as shown in fig. 9, and then to realize threading of the whole web by taping (shown in fig. 9).

The working mode of the cutting and conveying device of the utility model is further described below with reference to the accompanying drawings, but the protection scope of the utility model is not limited thereby.

As shown in fig. 8, in the conventional process of threading a roll 100 such as a pole piece, two workers are required to pull the pole piece from a feeding roller 1000 to a collecting roller 2000, and at the same time, cutting of the roll 100 is achieved by a cutting roller 3000, and after threading is completed, unreeling of the feeding roller 1000 can be automatically performed. In the above process, two coiled materials need to be manually worn by two operators respectively, because the thickness of the coiled materials is smaller, partial deformation and even belt breakage are easy to occur due to uneven stress caused by pure manual pulling, and the winding process is long in time consumption, large in pole piece consumption and low in working efficiency.

The utility model sets up the winding mechanism to optimize the threading process. Specific threading procedure as shown in step 1 of fig. 9, the coiled material 100 (for example, a pole piece or other coiled material such as a PET film, kraft paper, foil, etc. for threading a pole piece) fed from the feeding roller 1000 is wound manually by the conveying roller 3 onto the first reel 11 and the second reel 12 (the cutting conveyor may be positioned close to the feeding roller 1000 to reduce the threading distance), and then the conveying roller 3 and the first reel 11 and the second reel 12 are linked (not shown), and the coiled material winding on the first reel 11 and the second reel 12 is realized by the winding mechanism, and the length of the wound coiled material 100 may be 15 meters, for example. As shown in step 2 of fig. 9, after the winding is completed, the first reel 11, the second reel 12 are out of the linkage with the conveying roller 3, and the first reel 11 and the second reel 12 can realize unreeling of the web material to the collecting roller 2000 independently of the conveying roller 3. As shown in steps 3-4 of fig. 9, the collection roller 2000 connects the coiled material with reduced width on the collection roller 2000 to the coiled material on the feeding roller 1000 by means of taping, thereby completing the taping process.

Specific details of the operation of the winding mechanism and the cutting conveyor are described below. As shown in fig. 7, after the conveying roller 3 bypasses the coiled material 100, the U-shaped frame 61 is driven to descend by the lifting member 62 of the lifting mechanism 6, and the cutting mechanism 4 descends to cut the coiled material 100 along the length direction, at this time, an operator lightly pulls the coiled material 100 and winds the peripheries of the first reel 11 and the second reel 12, so that the initial positioning of the coiled material 100 between the two reels and the conveying roller is realized. Thereafter, as shown in fig. 2 and 4, the operator tightens the first connection structure 224 and the second connection structure 225 (handle bolts in the drawings), rotates the operation portion 21 to drive the rotation of the capstan 221 in fig. 3, at which time the conveying roller 3 starts rotating, the web 100 is conveyed to the reel, and at the same time, the first driven member 222 and the second driven member 223 (pulley transmission in the drawings) connected to both ends of the conveying roller 3 start to connect the first reel 11 and the second reel 12 in fig. 1, and the first reel 11 and the second reel 12 start to wind synchronously. After the winding is completed, the first and second connection mechanisms 224 and 225 are released, at which time the first and second spools 11 and 12 may each unwind to the collection roller 2000 of fig. 9. The winding mechanism can synchronously collect the cut coiled materials respectively, has the same conveying and winding speeds, is not easy to generate local deformation and fracture of the coiled materials, is stable and quick, and has high operation efficiency. In addition, the two coiled materials collected by the utility model after cutting can be discharged at different speeds, and the operation is flexible.
