Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1-2, the present application discloses a slitting machine, which includes an upper cutter shaft 3, a plurality of upper cutters 1 spaced apart from each other on the upper cutter shaft 3, a lower cutter shaft 4, and a plurality of lower cutters 2 spaced apart from each other on the lower cutter shaft 4. Referring to fig. 1 in particular, the upper cutter shaft 3 and the lower cutter shaft 4 are arranged in parallel; on the cutter shaft, a group of upper cutters 1 corresponds to a group of lower cutters 2; the base material passes between upper cutter 1 and lower cutter 2, and when cutting, each group of upper cutter 3 and lower cutter 4 cooperation that correspond the setting decide the base material, makes the base material divide into many little strips that accord with the width needs.

As will be readily appreciated, in many cases, the substrate may not be cut into multiple strips; in actual cutting, leftover materials may remain on one side or two sides of the base material; the width of the leftover materials is narrow and is not enough to form small strips meeting the width requirement.

It should also be explained that the lower blade shaft 4 is a blade shaft located below the substrate during cutting, and the substrate passes between the upper blade 1 and the lower blade 2, and has a tendency to lean against the lower blade shaft 4 due to its own weight. Especially, the leftover material cut from the edge of the base material is provided with a winding mechanism capable of accurately controlling the tension at the downstream for traction because the leftover material has a narrow width and is not like a small strip meeting the requirement, and the leftover material is most likely to fall to the lower cutter shaft 4 due to the stripping force after being cut from the main body of the base material.

In the branch strip machine that this application provided, go up cutter 1 and lower cutter 2 and be the sharp sword. Referring specifically to fig. 2, the cutting edges of the upper cutter 1 and the lower cutter 2 are suspended, that is, the cutting edge of the lower cutter 2 for cutting the substrate is spaced from the axial surface of the lower cutter shaft 4. In this case, the leftover material cut from the edge of the base material is easily fallen down and directly falls onto the shaft surface of the lower cutter shaft 4. If the leftover material falls down, the position of the leftover material deviates, on one hand, the position of a small strip adjacent to the leftover material can be influenced, the small strip deviates along with the position of the small strip, and even the width of the small strip is influenced, so that the cutting fails; on the other hand, the position deviation of the leftover material can affect the tension of the leftover material, and even can cause the tension of the whole base material to change, and finally the cutting is affected.

In order to avoid the leftover material from falling, the application provides a leftover material supporting mechanism which comprises a guide ring 10, wherein the guide ring 10 is arranged on one side of a lower cutter 2 and is provided with a bearing surface 11 extending along the axial direction of a lower cutter shaft 4; the bearing surface 11 is attached to the side surface of the cutting edge of the lower cutter 2 and extends along the axial direction of the lower cutter shaft 4, and cut leftover materials can be lapped on the bearing surface 11.

Wherein, the supporting surface 11 is attached to the side surface of the cutting edge of the lower cutter 2, after the substrate is cut, the supporting surface 11 supports the end part of the leftover material, and the end of the leftover material is adjacent to the small strip; that is, the supporting surface 11 is very close to the cutting position, that is, the position where the upper and lower cutters cooperate to cut the substrate; so, holding surface 11 can also guarantee to cut the stability of position except can holding leftover bits, and then guarantees to cut the effect. Further, the width that bearing face 11 is long than the leftover bits along the axial width of arbor to hold whole leftover bits, avoid the leftover bits to leave the side of bearing face 11 and appear lodging, finally still influence the position of leftover bits.
