Compared with the prior art, the plastic file cutting-off device has the advantages of being high in secondary positioning precision by adopting the upper and lower cutters to cut off slitting points in a moving cutter position mode, and has a high slitting speed achieving 100 times per minute; the integral repairing length of a manufactured bag depends on the front-and-back reciprocation displacement of the cutter whole bodies, and the mechanical inertia is small; the traction tension is stable without large change in one step of bag manufacturing; the cutters are easy to align; and the percent of pass of finished products is up to 98%.

Description

A kind of plastic sheeting shearing device
Technical field
The utility model relates to plastics masking field, particularly a kind of plastic sheeting shearing device.
Background technology
The plastic sheeting shearing device is one of equipment indispensable in the plastic sheeting processing, the conventional plastic film cutting device adopts pneumatic principle usually, utilizing cylinder to drive piston rod moves up and down, thereby driving eccentric disc swings, drive gangbar, do the up-and-down reciprocating shearing so that connect the upper lower cutter of gangbar, finally realize shearing work.But having a lot of shortcomings in the traditional approach, is cylinder such as the power source that adopts, and easily produces larger noise pollution, affects the workman healthy.In addition, adopt cylinder to do power source, can produce shear action slow, because the motion itself of cylinder is insensitive, cause lower cutter to carry out shear action slow, traditional cutting method shear rate only reaches 70 times/minutes.
In addition, utilize cylinder to do power source, adopted the twin-tub drive pattern, have synchronous difference between twin cylinder, reciprocating also can cause mechanical wear, uses effect thereby reduce.
The utility model content
For the drawback that above-mentioned conventional art exists, the utility model is intended to propose a kind of plastic sheeting shearing device of non-cylinder power source.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of plastic sheeting shearing device, comprise, lower cutter and upper, the incision knife rest, knife drive mechanism, knife rest travel mechanism, described upper cutter sets up and places frame entablature side, lower cutter sets up and places frame sill side, on, lower cutter is arranged at up and down on the cutoff knife rack in opposite directions, be fastenedly connected by the bolt activity, frame entablature and frame sill respectively concentric are connected two groups of piston-type cylinder posts and cylinder barrel, but frame entablature and the upper and lower displacement on the cylinder body after the combination of frame sill;
Described knife drive mechanism comprises cutter motor, transmission component, and wherein cutter motor is servomotor, and transmission component is by two gangbar, two groups of eccentric wheels, Timing Belt and synchronous pulleys, driving shaft; One of two gangbar is connected with the top of two cylinder posts respectively, and the other end is connected with two groups of eccentric wheels, and two of driving shafts are connected with two groups of eccentric connecting hole axle center, are fastenedly connected by puller bolt, and a synchronous belt wheel radially is set at the middle part of driving shaft;
Described knife rest travel mechanism is motor drive mode, connects a Power Drive Unit at the end of displacement driving shaft, and this device comprises displacement motor, reduction box, bevel gear, universal driving shaft, driving gear and driven gear.
The mobile motor of described knife rest travel mechanism is servomotor or stepper motor.
Driving shaft in the described knife rest travel mechanism in universal driving shaft and the knife drive mechanism each other antarafacial be arranged in parallel.
Adopted the plastic sheeting cutting method of non-cylinder power source compared with conventional art the utility model, had a noise low, without magnetic valve commutation sound; Action response time is short, and actuating speed is sensitive, can accomplish that moment drives and stops; Whole cut-off velocity is high, can reach 160 times/minutes; Long service life.

Among its figure: the 1-upper cutter; The 2-lower cutter; The 3-gangbar; 4-angular wheel 1; 5-angular wheel 2; 6-displacement adjusting handle; The 7-eccentric wheel; The 8-Timing Belt; The 9-synchronous pulley; The 10-cutter motor; The 11-gangbar; The 12-signal panels; The 13-inductive switch; The 14-driving shaft; The 15-screw rod; 16-screw rod slide block; 17-lower slide slide block; The 18-lower slide; The 19-ball-joint; 20-cylinder post; 21-frame entablature; The 22-cylinder barrel; 23-frame sill; The 24-guide rail; 25-film delivery groups roller; 26-upper tool post slide block; The 27-plastic sheeting; The 28-cylinder.
The specific embodiment
The below is elaborated to the utility model with reference to the utility model preferred embodiment and Figure of description.
When adopting non-cylinder power source, cutter motor 10 drives upper cutter 1 motion, carries out cutting of polybag, and then upper cutter 1 turns back to highest order and returns to opening, finishes do action one time.
Cutter motor 10 drives synchronous pulley 9, via Timing Belt 8, connect driving shaft 17, eccentric wheel 7, driving shaft 14 is under the driving of cutter motor 10 power, drive simultaneously 7 rotations of two side eccentric wheels, eccentric wheel 7 transmission gangbar 11 stop at highest order after the cut-out each time, are to be realized by inductive switch triggering signal dish.
The above only is a preferred embodiment of the present utility model; can not limit protection domain of the present utility model with it; the utility model also can have other structural change; so long as the equalization of doing according to protection domain of the present utility model changes and modify, all should belong in the scope that the utility model contains.
