Description
Technical field
The utility model belongs to biodegradable plastics bag processing equipment field, and in particular to arrives a kind of chopping block of punching machine
Device.
Background technology
Existing polybag punching machine, there are two two sets of die cutting devices of working face for general tool, can be punched two pile plastics simultaneously
Bag.After two pile plastic foils are respectively delivered on two chopping blocks in left and right by conveying device, blanking units move downward, by plastic foil
The shape (also referred to as convenient bag or plastic bag) with hand plastic bag is cut into, reset is then lifted.Following chopping block can rotate
Certain angle, tool marks will not be on the same point of chopping block when making to be punched again, i.e., tool marks will not repeat.Due to impact force
Greatly, frequency is high, the chopping block although lower also can automatic rotation angle, always turn over, the tool marks that turn round concentrate on chopping block
In a few road annular locations, that is, it is on the track of the same circle.The place that tool marks occurs in chopping block just must be lossy, and work is not
Ring-shaped groove will be formed for a long time, moreover the shape of stamping knife is in " W " shape, the groove that the chopping block of rotation occurs just is more than one
Item, and the depth of per pass groove differs, and there is the step of high recessed injustice between per pass groove.This seriously affects effect of blurting out,
The problems such as, punching irregular in the presence of punching is not thorough, tears, chopping block also must be replaced often, and production cost is high.
Notification number is that the Chinese utility model of CN203557755U discloses a kind of slug of Automatic Plastic material bag punching machine
Board group part, slug plate and driving device are located in a groove body；Driving device include two worm screws, at least one worm gear and
Two limit switches, two worm screws are rotatably installed in the front and back both sides of groove body respectively in parallel to each other, and worm gear is located at two snails
Between bar, it is meshed with the worm screw on both sides；It is equipped with slug board slot in the upper surface of worm gear center, slug plate is located at the slug board slot
It is interior；Two limit switches are separately mounted in the right and left of groove body.The utility model is replaced by two pairs of worm and worm gears
Operating, stamping knife often be punched once, while driving slug plate to rotate an angle set, also moves left and right one and sets
Distance controls left and right by limit switch and moves back and forth, but the utility model driving mechanism is complicated, needs that limit is additionally arranged
Mechanism, and need to coordinate the movement between two worm screws, it is also necessary to coordinate to move between worm screw and position-limit mechanism, driving is caused to fill
It is complicated to set coordination, and then leads to that increased production cost.
Utility model content
The purpose of this utility model is that：In order to solve to need in the prior art that position-limit mechanism, and driving device is additionally arranged
Coordinate complicated problem, provides a kind of biodegradable plastics bag punching machine chopping block device, the utility model driving device is simple
Reliably, driving device internal coordination is consistent, long operational time, and service life of chopping block is long.
The technical solution adopted in the utility model is as follows：
A kind of biodegradable plastics bag punching machine chopping block device, including rack are provided with chopping block in the rack, described
Chopping block bottom is provided with driving device, and the driving device includes the connecting rod of the chopping block bottom setting, is set in the rack
It is equipped with guide rail, the connecting rod can move back and forth in guide rail along the course bearing of guide rail, be provided with slot in the connecting rod, institute
Axis of the axis perpendicular to the connecting rod of slot is stated, sliding block is provided in the slot, the sliding block can be in slot along the rail of slot
Mark direction moves back and forth, and is hinged with crank on the sliding block, the crank is hinged in rack.
Further, the chopping block bottom is fixedly connected with shaft, and gear, the connection rod set are arranged in the shaft
It is located at the bottom of the shaft, rack is additionally provided in the rack, the rack is engaged with the gear.
Further, telescoping cylinder is provided in the rack, the telescopic rod of the telescoping cylinder is connected with the rack back side,
The telescoping cylinder makes rack and pinion detach or engage.
Still further, the chopping block is set as two, two shafts are connected by connecting rod, and the slot is arranged described
On the midpoint of connecting rod；The rack is arranged in parallel in the front and rear sides of rack.
In conclusion by adopting the above-described technical solution, the utility model has the beneficial effects that：
1, in the utility model, sine that the left and right displacement of chopping block is made up of connecting rod, slot, sliding block, crank and guide rail
Mechanism realizes that driving device itself is harmonious, the rotation of crank handle turns sliding block, and sliding block is existing relative to slot because of the limitation of slot
It is that course bearing along slot moves back and forth in slot, slot and connecting rod are together in guide rail for rack along guide rail
Track straight reciprocating.Because the left and right displacement of the characteristic of sine mechanism itself, connecting rod and chopping block is limited, that is, it is not required to
Position-limit mechanism is additionally set, and connecting rod and the left and right displacement range of chopping block can by the length-adjusting in crank and slot,
Compared to the prior art, control program need not be compiled again to coordinate the operation of each component inside driving device, reduce production cost.
The utility model is due to that can carry out large-scale left and right displacement so that the punching trace on chopping block is no longer limited in chopping block
Heart position improves the service life of the utility model.
2, in the utility model, the left rotation and right rotation of chopping block is realized by rack-and-pinion, and chopping block bottom, which is fixedly connected with, to be turned
Axis is arranged with gear in shaft, and connecting rod is set on the bottom of shaft, and rack, rack and the tooth are additionally provided in rack
Wheel engagement, when shaft, chopping block and connecting rod move together, because rack remains stationary as, forces gear to rotate, that is, drives
Chopping block rotates, and motor need not additionally be arranged.Mechanism is simple and reliable, stable working, long lifespan, and the prior art will not occur
It is middle using worm and gear there is a situation where self-locking and cause chopping block that cannot rotate.
3, in the utility model, in order to keep the movement of chopping block more diversified so that punching trace can preferably gather
The entire working face of chopping block is provided with telescoping cylinder in rack, and telescopic rod and the rack of telescoping cylinder do not have a side end face of tooth to be connected,
Telescoping cylinder makes rack and pinion detach or engage, and when rack and pinion detaches, chopping block only does left and right displacement, does not rotate, when
When wheel and rack engages, chopping block does the compound motion of left and right straight-line displacement and rotation.
4, in the utility model, in order to increase yield, chopping block is set as two, meanwhile, two shafts are connected by connecting rod
It connects, slot is arranged on the midpoint of connecting rod；Rack is arranged in parallel in the front and rear sides of rack,；Two telescoping cylinders control a left side respectively
The clutch of rack, right rack and corresponding gear avoids that is, so that the movement locus of left and right chopping block is not consistent on punching machine
Chopping block scrap simultaneously and bring loss to producer, avoid reduction production efficiency.
