Abstract
The utility model relates to a cutting-type paper breaking mechanism of a rewinder, which comprises two live-rollers which are close and paralleled to each other, and paper passes between a knife roll and a packing paper roll, and a long-strip-shaped cutting tip and a transmission mechanism which drives the cutter blade to move are arranged inside the knife roll, and a blade of the cutting tip can extend out of or draw back to the knife roll; the outer cylindrical surface of the packing paper roll is provided with a long-strip-shaped groove, and the ratio of transmission between the packing paper roll and the knife roll satisfies that when the knife roll rotates a circle, the cutting tip on the knife roll can justly correspond to the groove on the packing paper roll, so that the blade of the cutting tip can be inserted into the groove of the packing paper roll. When breaking the paper, the knife roll and the packing paper roll, which rotate continuously, are utilized to cut the paper, so that the paper can be cut off during the high-speed progression, thereby, the production efficiency of the rewinder is greatly improved.
Description
Technical field
The utility model relates to the cutter cut paper breaking mechanism in the rewinding machine of producing paper roll, particularly rewinding machine.
Background technology
Rewinding machine is finished coil paper volume and just must be fast the paper of paper roll afterbody be cut off whenever rewinding in producing the process of paper roll, and the mechanism that finishes this process is called the paper breaking mechanism of rewinding machine.The paper breaking mechanism of rewinding machine has multiple, and wherein a kind of paper breaking mechanism is called cutter cut paper breaking mechanism, is characterized in utilizing cutter that the paper of paper roll afterbody is cut off.In the prior art, the shortcoming of cutter cut paper breaking mechanism is to move as cutting-up in cutter surface along paper on the direction of advancing perpendicular to paper, therefore in cutter cutting paper, must stop the motion of advancing of paper earlier, have a strong impact on the production efficiency of rewinding machine thus.
Summary of the invention
The purpose of this utility model provides a kind of cutter cut paper breaking mechanism that need not to stop the rewinding machine that paper advances when disconnected paper.
The utility model is achieved in that the cutter cut paper breaking mechanism of rewinding machine comprises two close to each other and parallel live-rollerss, paper is through between two live-rollerss, be provided with the strip shape blade and drive the transmission device that blade moves in a live-rollers therein, for ease of describing, this live-rollers is called rotor, the length direction of blade and the axially parallel of rotor, under the drive of transmission device, the blade of blade can protrude from the outer cylinder or withdrawal rotor of rotor; The outer cylinder of another root live-rollers is provided with the strip shape groove, for ease of describing, this live-rollers is called the packing paper roller, the axially parallel of the length direction of groove and packing paper roller, the revolution ratio of packing paper roller and rotor satisfies whenever rotor rotates a week, blade on the rotor is just corresponding with the groove on the packing paper roller, makes the blade of blade can insert in the groove of packing paper roller.Principle of work of the present utility model is: when the intact coil paper volume of rewinding machine rewinding needs to break paper, drive the blade action by the transmission device in the rotor, make the blade of blade protrude from the outer cylinder of rotor and insert in the groove of packing paper roller, to cut off through the paper of the paper roll afterbody between rotor and the packing paper roller with this, realize disconnected paper; Behind the disconnected paper, drive blade by the transmission device in the rotor again and reset, make in the blade withdrawal rotor of blade.By above-mentioned principle of work as seen, the utility model utilizes not stall moving rotor and packing paper roller that paper is cut off, thereby need not to stop the motion of advancing of paper.
The utility model has the advantages that and when paper high speed is advanced, fast paper to be cut off, improved the production efficiency of rewinding machine greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Referring to Fig. 1, the cutter cut paper breaking mechanism of rewinding machine comprises two close to each other and parallel live-rollerss 1,2.Paper 3 passes through between two live-rollerss.What see among the figure is the transversal surface of paper 3, and the direct of travel of paper 3 is perpendicular to the figure paper plane.Two live-rollerss keep interaction relation by two gears in meshs 4,5.The mode that drives two live-rollerss rotations can adopt motor to pass through the mode of synchronous band or gear drive.Be provided with strip shape blade 6 in a live-rollers 1 therein.For ease of describing, live-rollers 1 is called rotor.The axially parallel of the length direction of blade 6 and rotor 1.In rotor 1, be provided with the transmission device that drives blade 6 actions.As preferred forms, the transmission device of present embodiment is a four-bar linkage, as frame, two side links 7,8 that link with rotor 1 are parallel to each other this four-bar linkage with rotor 1, and blade 6 is connected the connecting rod that constitutes between two side links 7,8 in the four-bar linkage.When side link 7 counter-clockwise swings wherein, the blade that can order about blade 6 protrudes from the outer cylinder of rotor 1; When wherein side link 7 cws are swung, can order about in the blade withdrawal rotor 1 of blade 6.It is to make blade in the course of action that protrudes the rotor outer cylinder that present embodiment adopts the advantage of four-bar linkage, from perpendicular to paper 3 be parallel on the both direction of paper 3 and all paper 3 produced cutting forces, thereby guarantees fast paper 3 to be cut off.The blade of blade 6 is preferably zig-zag, so more helps the fast shut-off paper.The four-bar linkage of present embodiment also is provided with the passive constraint member---and side link 9, the motion of 9 pairs of four-bar linkages of side link does not provide constraints, but can improve the stressed and equilibrium condition of mechanism.Also can increase more parallel side link by that analogy.In order to drive the four-bar linkage action, present embodiment adopts cylinder 10 as propulsion source, cylinder 10 is fixed on outside the rotor 1, the piston rod 11 of cylinder stretches in the rotor 1 from the end face center of rotor 1, and link together by the bulb bearing with a side link 7 in the four-bar linkage, when piston rod 11 is made fore and aft motion, can drive side link 7 and swing back and forth.Except adopting cylinder, can also adopt electromagnet, motor etc. as propulsion source.
The outer cylinder of another root live-rollers 2 is provided with strip shape groove 12.For ease of describing, live-rollers 2 is called the packing paper roller.The axially parallel of the length direction of groove 12 and packing paper roller 2.Packing paper roller 2 satisfies whenever 1 one week of rotation of rotor with the revolution ratio of rotor 1, and the blade 6 on the rotor 1 is just corresponding with the groove 12 on the packing paper roller 2, makes the blade of blade 6 can insert in the groove 12 of packing paper roller 2.The quantity of groove 12 can not have only one, two grooves for example can be arranged, and two grooves are axis of symmetry rotation symmetry with the axis of packing paper roller 2, whenever rotor 1 rotates a week, packing paper roller 2 just rotates half cycle, so same corresponding relation that can guarantee blade 6 and groove 12.
Because the function that the tractive paper is advanced can be finished by other mechanism of rewinding machine, rotor 1 and packing paper roller 2 needn't closely clip paper 3, therefore another kind of evolution structure of the present utility model is, the outer cylinder of rotor 1 and packing paper roller 2 can not be the face of cylinder, for example can be multi-prismatic surface, but must guarantee the corresponding relation of blade 6 and groove 12.Certainly, as version the most easy to implement, the outer cylinder of rotor 1 and packing paper roller 2 should be the face of cylinder, and the gait of march that the outer circumference of rotor 1 and packing paper roller 2 equates, the excircle linear velocity equates and equal paper 3.
