Abstract

The invention provides a paper cutter for reel disk wrapper, which belongs to the technical field of paper cutter machinery, and aims to solve the problems of complicated structure and high cost of the prior paper cutter. The paper cutter for the reel disk wrapper comprises an unreeling roll, a driving roll, a friction roll, a fixed blade and a rotary blade, wherein one end of a blade rotating shaft is provided with a connecting disk of a tension spring; a fixed head of the tension spring is arranged on the edge of the connecting disk ; the tension spring is sleeved between the fixed head of the tension spring and the bottom of a frame; a shaft head on the other end of the blade rotating shaft is provided with a driving disk; a deflector rod is vertically arranged on the edge of the driving disk; a rotating push rod is arranged on a power output shaft vertically; a motor drives the push rod and the deflector rod to rotate; the deflector rod drives the blade rotating shaft to rotate; when the fixed head of the tension spring rotates to the highest point, under the action of the tension spring, the rotary blade is accelerated to rotate; and when the rotary blade is tangential with the fixed blade, paper is cut off. The paper cutter has the advantages of simple structure and low manufacturing cost for equipment.

Description

Paper cutter for bobbin disk wrapping paper

Technical field

The invention belongs to the sheet cut machine technical field, relate to a kind of paper cutter for bobbin disk wrapping paper.

Background technology

In prior art, the paper cutter kind is a lot, generally form by frame, unwinding device, paper feeder and paper cutter several sections, the cut paper of its paper cutter partly adopts vertical cut paper mode to carry out work, be paper when being fed forward paper vertical mutually with cutting knife, cutting knife is done in vertical direction and is pumped, and when moving to low spot paper is cut off.This paper cutter complex structure, control is accurate, to the yardage accurate positioning of being cut, the matched in clearance precision between the backing plate of blade and paper, the manufacturing cost of equipment is higher.Not high for some paper qualities, cut out the length of paper and the less demanding cutting work of accuracy of otch, the paper cutter that service precision is higher, it is excessive to cause equipment to drop into, the problem of functions of the equipments waste.

At problems of the prior art, it is relatively low to the invention provides a kind of cost, controls conveniently, and paper cuts off effective, the paper cutter for bobbin disk wrapping paper that the production required precision is not high.This machine is made up of frame, unwinding device, paper feeder and paper cutter, unwinding device is installed in an end of frame, constitute by let off roll, reel paper is installed on the let off roll, paper feeder is installed in the top of the frame other end, constitute by drive roll and hold-down roller, two rollers are arranged at horizontal parallel longitudinal, one termination of drive roll has the drive roll drive motors, hold-down roller is pressed on the drive roll, the rotating shaft two ends of hold-down roller are installed on the frame with hold down gag respectively, and wrapping paper passes through between drive roll and hold-down roller; Paper cutter is positioned at the below of paper feeder on the frame, paper cutter is made up of fixed blade and rotating blade two parts, reel paper passes between two blades, fixed blade is installed on the blade holder of frame, rotating blade is installed on the blade rotation axle, on the blade rotation axle is axial a tangent plane is arranged, and rotating blade is installed on this tangent plane, the blade end of blade stretches out outside the cylindrical circumference of rotating shaft, and an end of blade rotation axle is connected with a blade rotation axis drive motor; The spindle nose at blade rotation axle two ends stretches out outside the sidewall of frame, stretch out the outer spindle nose of sidewall, one end is equipped with an extension spring terminal pad, fixedly head of an extension spring is installed on the terminal pad edge, extension spring one end is sleeved on the fixing head of extension spring, the other end is fixed on the bottom position of frame, on the spindle nose of the blade rotation axle other end, be fixed with the driving-disc of a blade rotation axle, be vertically installed with one and driving lever on the driving-disc edge, the power output shaft of blade rotation axis drive motor and blade rotation axle arranged in co-axial alignment, diaxon is not connected, on the spindle nose of power output shaft, be equipped with one with its axial vertical rotating push-rod, push rod rides on the driving lever when rotating, the promotion driving lever rotates, the blade rotation axis drive motor clockwise rotates, the promotion driving lever clockwise rotates, the fixing head of extension spring and driving lever are separately fixed at the spindle nose two ends of blade rotation axle, their locus in the vertical direction staggers mutually, not on sustained height, when the fixing head of extension spring was positioned at peak, the position of driving lever just in time was positioned at minimum point.

Use this equipment, because blade rotation axle one end is equipped with extension spring, the blade rotation axle separates with the power output shaft of its drive motors, the blade rotation axle relies on the push rod on the drive motors spindle nose to promote, push rod is overlapped in rotation process on the driving lever of blade rotation axle spindle nose, the promotion driving lever rotates, driving lever drives the blade rotation axle and rotates, when the fixing head of the extension spring of extension spring terminal pad on the blade rotation axle turns to the peak position, under the pulling force effect of extension spring, the rotating blade velocity of rotation is accelerated, this moment, driving lever broke away from push rod, quick rotation, the rotating blade on being fixed on the blade rotation axle turn to fixed blade when tangent, and rotating blade is about to paper and cuts off.Improve the velocity of rotation following cutter speed of blade when improving cut paper just, to obtain better cut paper effect.

For the present invention can be controlled to some extent to the length that institute's cut paper is opened, only need on drive roll and blade rotation axle, to use frequency control motor, by regulating the friction speed of two motors, can control the paper feed length of paper and the break time of blade, thus the yardage that control is cut off.

Cut off effective purpose in order to be issued to paper in the not high condition of required precision, the knife edge part of fixed blade and rotating blade is designed to zigzag, when two blades are pressed close to, the convexconcave part of profile of tooth just in time intersects mutually and is tangent, like this, even the contact-making surface gap when two blades suit is inhomogeneous, the situation that the paper incision position exists fraction not cut off, blade also can guarantee that the paper that cuts off separates with paper from the incision tear fracture.Use the present invention, the otch indention of paper.

From such scheme as can be seen, the present invention has simple in structure, and equipment manufacturing cost is low, uses control convenient, and the success rate height that paper cuts off is to the less demanding advantage of the paper quality of being cut.
