Abstract

The invention discloses a novel cutting machine. The novel cutting machine comprises a direct current main motor, a cutter bar and a blade, symmetrical grinding wheel groups, a micro motor, a lifting screw rod and a movable base plate. The current main motor is a current main adjustable-speed motor which replaces an alternating current motor, the inside of the cutter bar is provided with a ceramic column. The excircle of the ceramic column and the back of the blade form linear frication, and the friction of the blade can be reduced. The symmetrical grinding wheel groups are provided with a main body frame on which grinding wheel groups of bilateral symmetry are arranged, grinding wheels lean against two sides of the cutting edge of the blade, and the movement of the blade can drive the grinding wheels to rotate to achieve the aim of automatic cutter sharpening. The grinding wheel groups are fixed at lower end of the lifting screw rod, and the micro motor rotates or rotates reversely under circuit instruction to drive the lifting screw rod to run vertically. The novel cutting machine is simple in structure and low in costs and has the advantages of being low in noise, convenient to operate, long in service life, novel in structure and the like.

Description

A kind of Novel cutting machine

Technical field

The present invention relates to a kind of clothes, leather, lodge, bedding processing machine, be specifically related to a kind of novel cloth cutter.

Background technology,

1, prior art cutting machine; By main motor, drive all parts, main motor shaft is provided with cam, and a connecting rod is arranged at cam top, during electric machine rotation, drags slide block, and the blade that makes to be fixed on slide block back and forth moves, thereby reaches dissection.Cam cylindrical side rubs mutually with the cylindrical side of a friction wheel, power is sent to knife sharpening device, the too much sleeve gear of warp mechanism changes power simultaneously, drive left and right two collar molding sand band rotations, one drives double threaded screw to make knife sharpening device lifting, realization, when blade passivation, moves sharpening work up and down.Because sharpening system is through many cover mechanical switch direction of motion, train of mechanism is cumbersome, while actually employed, rubber and plastic friction pulley and knife sharpening device gear will be worn 2 in the short period of time, knife bar is thinner, because knife bar will bear the alternating current generator pressure of 15 kilograms, form knife bar produces and waves when work, when cutting cloth turning, blade distortion, causes blade action to be obstructed, knife bar heating motor stalling.3, the reciprocating motion of blade and knife bar produce strong friction when cutting cloth, and power of motor can not get effective performance, causes the waste of the energy.4, in the situation that friction load can not get solving, continue to increase power of motor and volume, because alternating current generator is overweight, during operation, handle firmly presses down, and causes the sinking of mobile chassis.The grinding tool of 5, whetting a knife is that abrasive band makes moist, and is stained with machine oil and all can not uses with abrasive band, and loss is fast.Therefore, the cutting machine fault of prior art is high, and service life is short, and operation is used inconvenient, has not been suitable for the needs that modernization industry is produced.The invention reside in provide a kind of and reduce that power of motor, noise are little, the cutting machine of long service life, easy to operate, novel structure.

The technical solution adopted for the present invention to solve the technical problems is:

Summary of the invention

In order to overcome the cutting machine complex structure of prior art, rapid wear is perishable, the shortcoming of faults frequent, the invention provides a kind of Novel cutting machine, comprise micromachine and lifting screw, knife sharpener sub-assembly, direct-current main motor, knife bar and blade, mobile chassis, as micromachine and lifting screw, knife sharpener sub-assembly is arranged on direct-current main motor outer cover, described micromachine, tap switch starting sharpening instruction, micromachine forward, drive nut makes screw mandrel downward movement, be that knife sharpening device is descending, while touching the end, limit inferior switch switches to reversion, be that knife sharpening device is up, to the highest, limes superiors switch circuit breaking stops, realizing knife sharpening device up and down reciprocatingly moves at blade, complete sharpening work.

Described knife sharpener sub-assembly comprises main frame, main frame top is provided with the adjustable bowl front and back of abrasive wheel and the adjusting seat board of angle, above regulating seat board, be provided with a bowl molding sand wheel carrier, bowl molding sand wheel carrier one end is provided with a bowl abrasive wheel, and bowl abrasive wheel is by the reciprocating motion of blade, the object that drive emery wheel High Rotation Speed reaches automatic grinding.The grinding carriage other end is provided with spring, the cutting degree of the adjustable emery wheel blade of spring pressure.The stage casing of grinding carriage is provided with driving shaft, and a bowl molding sand wheel carrier can be moved left and right on driving shaft, is convenient for changing a bowl abrasive wheel.

Described main motor, main motor adopts direct current adjustable speed motor to replace existing alternating current generator, alleviates the load of knife bar.

Described knife bar and blade; In knife bar groove, be interval with high-hardness ceramic post, the cylindrical side of ceramics pole and blade tool back plane form line friction, to reduce the friction of blade and knife bar.In the bottom of knife bar, rear side adds roller, with the sinking that prevents that mobile chassis is middle.Therefore; The advantages such as that the present invention has is energy-conservation, use cost is low, noise is low, easy to operate, life-span length, novel structure.
