Description

The high speed cutting machine

One, technical field

The utility model relates to a kind of equipment, especially high speed wide cut cutting apparatus that printing and wrapper and film are cut.

Two, background technology

Cutting machine is the equipment that printing and wrapper and film are cut, cut as BOPP, CPP, BOPET, PVC, vacuum plated aluminum film etc., cutting machine comprises motor and servo-control unit, frame, bearing, unreels, wrap-up, cutting knife and grooving, leveling roller, deflector roll, pressure roller and unreel lifting and composition such as width adjusting, Tension Control, photoelectric error correction and pneumatic braking device, floating cylinder, clamping cylinder

The wrap-up structure of existing cutting machine is as follows, wind-up roll and hold-down roller are close to, can be drive roll, the rolling roll shaft is pressed on the hold-down roller by the cylinder bearing capacity, and material is more and more thick when rolling, and the material volume was still heavier when especially the cutting machine of wide cut degree cut into four volumes, might cause the pressure of rolling inhomogeneous, the variable angle of rolling base-material and pressure roller may make the air between rete all do not extruded, and has influence on the rolling quality.Certainly, the structure of high speed wide cut cutting machine more needs reasonable Arrangement;

In addition, because wide volume is heavier, unreel necessity that frame lifting and width adjusting also have improvement and develop.

Three, summary of the invention

The purpose of this utility model is: provide a kind of splitting winding pressure even, the angle of rolling base-material and pressure roller is constant, guarantees the cutting machine of rolling quality.And be a kind of high speed wide cut cutting machine of reasonable Arrangement take-up position; Especially a kind of wide cut cutting machine.The purpose of this utility model also is to provide a kind of frame lifting and width adjusting high speed cutting machine more easily that unreels.

The utility model purpose is achieved in that a kind of high speed cutting machine, comprise mainframe, unreel lifting and width adjusting mechanism, pneumatic dancer, the leveling roller master draws deflector roll and pressure roller, the transition deflector roll, cutting knife (comprises cutter shaft, tool rest, following cutter grooved roll), shunting is rubber roll initiatively, the frame wallboard, the correction driving support seat, deflector roll, the pressure roller parts, crossbeam, roller arm, rolling bearing rolling arm reaches and the cooresponding pressure roller of rolling, the pressure roller cylinder, rolling clamps compositions such as cylinder, it is characterized in that rolling bearing rolling arm is located on the slip plane, other establishes the described rolling arm of an electronic screw mandrel interlock.

Its principle of work is as follows, cut the increase of rolling arm take-up diameter in the work, electronic screw mandrel reaches with the cooresponding pressure roller of rolling, electronic screw mandrel and controls interlock by servomotor, makes the rolling arm and keeps identical pressure or interval with the cooresponding pressure roller of rolling in the work of cutting.

Further improvement of the utility model is: the rolling bearing rolling arm of take-up position reaches the both sides that are distributed in mainframe with the cooresponding pressure roller of rolling respectively, and especially every side has two rolling bearing rolling arms to reach and the cooresponding pressure roller of rolling, and correspondence is carried out quadrisection.The slip plane at the rolling bearing rolling arm place of take-up position is located on the upset discharging platform, and the bottom of discharging platform is provided with the discharging cylinder.

Characteristics of the present utility model are: rolling arm and pressure roller translation, and its angle is constant, and rolling pressure is even, rolling quality height, and reasonable Arrangement take-up position.

The utility model is particularly useful for the film of 2200mm amplitude and following amplitude and cuts.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model

Mainframe 1, unreel lifting and width adjusting mechanism 2, pneumatic dancer 3, leveling roller 4, main traction deflector roll and pressure roller 5, transition deflector roll 6, cutting knife 7 (comprise cutter shaft, tool rest, cutter grooved roll) down, shunting initiatively rubber roll 8, frame wallboard 9, correction driving support seat 10, deflector roll 11, pressure roller parts 12, crossbeam 13, rolling bearing rolling arm 14, with the cooresponding pressure roller 15 of rolling, upset discharging platform 16, pressure roller cylinder 17, discharging cylinder 18 overturns.

Five, the specific embodiment

As shown in the figure, comprise mainframe 1, unreel lifting and width adjusting mechanism 2, described unreel lifting and width adjusting mechanism 2 comprise unreel main shaft 2-1, unreel arm 2-2, to the lift cylinder that unreels arm with unreel width adjusting screw mandrel 2-3, unreel lift cylinder and regulate, and width adjusting is regulated and unreeled arm 2-2 and realize in the position of main shaft with regulating screw mandrel 2-3.

Therefore, the present invention still is a kind of frame lifting and width adjusting high speed cutting machine more easily that unreels.

Pneumatic dancer 3, leveling roller 4, main traction deflector roll and pressure roller 5, transition deflector roll 6, cutting knife 7 (comprising cutter shaft, tool rest, following cutter grooved roll), shunting be rubber roll 8, frame wallboard 9, correction driving support seat 10, deflector roll 11 initiatively, pressure roller parts 12, crossbeam 13, rolling bearing rolling arm 14, identical with existing structure or similar with the cooresponding pressure roller of rolling 15, upset discharging platform 16, pressure roller cylinder 17, upset discharging cylinder 18.Rolling bearing rolling arm 14 is located at 18-1 on the slip plane, and slip plane is made of two slide bearings.The described rolling arm of electronic screw mandrel 18-2 interlock slides on slip plane.Electronic screw mandrel is driven by motor 19 and reducer arrangement 20.
