Description

A kind of unreeling for web-like broad-width material connects film device

Technical field

The utility model is related to the technical fields of web-like broad-width material more particularly to a kind of unreeling for web-like broad-width material to connect Film device.

Background technology

In the manufacture field of web-like broad-width material, it usually needs carry out uncoiling, processing to the parent roll material of web-like, then again The process of winding is processed when a parent roll needs replacing new parent roll after processing is completed, and traditional film mode that connects needs people Work pushes down two films, is bonded again after cutting, but such method can not achieve automated production, inefficient, and it is easily inclined to cut notch Difference, joint out-of-flatness are easy to have the gap at out-of-flatness, and using such mode connect film when, complete machine needs to shut down, shut down When, portioned product is long in the manufacturing procedure residence time, causes converted products is unqualified to cause prodigious waste, the cost of production It is relatively high, and must cause to produce there are one reduction of speed, shutdown, paper injection, raising speed, the process of normal operation when the replacement of new and old parent roll The production efficiency of product is relatively low, and to solve the problems, such as this, technical staff, which proposes one kind and may be implemented not shut down automatic unreel, connects film Device, such as patent " CN204568912U " discloses a kind of paper splicing mechanism, including frame, holder, swing arm cylinder, swing arm, sanction Knife cylinder and cut-off knife；The holder is located on the frame, and the holder is made of paper roll holder and small bracing strut；The paper roll Holder and the intersection of small bracing strut are arranged and are linked together；The both ends of the paper roll holder, which are respectively arranged with, can wind placement paper roll Disc paper winding device；The both ends of the small bracing strut are respectively set a shaft, the swing arm cylinder, the swing arm, described Cut-off knife cylinder and the cut-off knife are located at the upper right quarter of the frame.The paper splicing mechanism can be realized automatic when paper roll runs at high speed The success rate of splicing, high degree of automation, splicing is high, and splicing step does not need human assistance, can protect the safety of staff； The paper splicing mechanism drives cut-off knife cylinder and cut-off knife to reach precalculated position using swing arm, drives cut-off knife rotation by cut-off knife cylinder, makes Cut-off knife cuts the base material on old parent roll, and to cut off the base material on old parent roll, that realizes new and old parent roll connects film, which can be real Film cut-out now is connect than relatively thin base material, for thicker PET base material, the thickness of material is up to 500 μm, due to this kind of material The tensile strength of material is very high, using the cut-out that commonly cuts power and cannot achieve this kind of base material, cuts power if increased, cuts and produced Raw vibrations have been more than the allowable range of product processing technique, drastically influence the quality and stability of product.

Invention content

To overcome problems with existing in the prior art, tradition to connect film mode and can not achieve automated production, efficiency is not Height cuts the easy deviation of notch, and joint out-of-flatness, processing quality is bad, and the cost produced is relatively high, and efficiency is relatively low, And connect membrane technology automatically and be only applicable in and connect film than the automatic of relatively thin parent roll with base material, the thicker base material of base material, which cannot achieve, to be cut It is disconnected, cannot achieve it is automatic connect film, the utility model provides a kind of unreeling for web-like broad-width material and connects film device, including framework portion Part, moving parts and film cutting section is connect, the moving parts is mounted on the lower part of rack unit, described to connect film cutting section peace On rack unit, it is characterised in that：It is described connect film cutting section include swing arm component, swing arm driving component, pressure roller component, Cutting section and transition roller member two, the pressure roller component, cutting section and transition roller member two are mounted on swing arm component one end, The other end of swing arm component is connect with rack unit and swing arm driving component, and the swing arm driving component other end connects with rack unit It connects, swing arm driving component drives the rotation of swing arm component, and the cutting section is between pressure roller component and transition roller member two, institute It includes cut-out rack, cut-out driving part and cut part to state cutting section, and the cut-out driving part is mounted on cut-out rack On, the cut-out driving part driving cut part is moved left and right along cut-out rack.

On this basis, the cut part includes tool apron, cutter and cutter driving component, and the cutter is mounted on cutter On driving part, the cutter driving component is mounted on tool apron, and the cutter driving component driving cutter is done rotation movement.

On this basis, the cutter includes cutter and bottom knife, and the cutter and bottom knife are arranged up and down, described Cutter and bottom knife edge side contact with each other to form shearing edge.

On this basis, the cutter is circular shear blade, and there is a circular mounting hole in blade center position, the cutter with Cutter driving component connects.

On this basis, the bottom knife is circular shear blade, and there are circular mounting hole, the bottom knife in blade center position It is connect with tool apron by spring and bearing.

On this basis, the bottom knife side, which is divided into, meets knife face and back of the body knife face, and the edge for meeting knife face has upwards Protrusion, it is described the back of the body knife face edge there is chamfering, the knife face of meeting to be contacted with the side of cutter.

On this basis, the cutter driving component is servo motor.

On this basis, the cut-out driving part is no bar electric cylinders.

On this basis, the velocity interval of the no bar electric cylinders is 5m/s~8m/s.

Compared with prior art, the utility model has the beneficial effects that：

1, originally unreel connect film device using cut-out driving part driving cut part along cut-out rack move left and right, cutter portion Blades fit forms cutting edge to part up and down, to realize that the parent roll base material thicker to base material carries out transversely cutting, to ensure that thickness The new and old parent roll of base material connects the realization of film automatically.

2, it originally unreeling and connects film device using electric cylinders as cut-out driving part, the movement speed of electric cylinders is 5m/s~6m/s, The cut-off velocity that ensure that parent roll base material, base material break time is longer when overcoming left and right transversely cutting, and complete machine operation is slower Disadvantage improves the production efficiency of product.
