Abstract
The utility model discloses a kind of bag pulling mechanisms of soft material, it is adapted as including face tissue, driving device in the materials packaging operation such as sanitary napkin, it is rotated including motor-driven rotatable shaft band movable eccentric wheel, eccentric wheel drives swing arm to swing by first connecting rod, its main feature is that, swing arm free end drives drive seat back and forth to operate by second connecting rod, linkage seat is fixed on push rod, and strong magnet is installed in drive seat or linkage seat, drive seat and linkage seat are attached together by strong magnet, the mechanism is when push rod is stuck, push rod can be detached from the movement of swing arm, so as to avoid the damage generated to each component.
Description
Technical field
The utility model belongs to a kind of package packing machine technology, is related to a kind of driving device suitable for soft material packaging,
More specifically, be it is a kind of drive push rod to realize the bag pulling mechanism moved back and forth using swinging, to be adapted as include face tissue, is defended
Driving device in the materials packaging operations such as raw towel.
Background technique
Currently, materials packing machine mostly uses servo motor or cylinder as driving device, so as to right in operation process
The all parts of package packing machine are driven, though structure has the characteristics that accurate or simple, also bring deficiency thus, and one
It is that servo motor is at high cost, the manufacturing cost of machine will be greatly increased by carrying out control using more servo motors, reduce enterprise
The benefit of industry will lead to second is that being controlled using cylinder and generate complicated supply air line, and can bring when air pressure is unstable
Problem not in place is acted, packing material is easily caused to cannot be introduced into scheduled position.
For this purpose, people devise again it is a kind of by eccentric wheel by connecting rod drive swing arm motion mechanism, it using swing arm come
Bag pulling mechanism is driven, provides the mode of another driving to bag pulling mechanism, still, there are also problems for this driving method, when
When bag pulling mechanism gets stuck, if finding and handling not in time, it will damaged to mechanism part.
Summary of the invention
The purpose of this utility model is to provide a kind of bag pulling mechanism of soft material, which is passed through by eccentric wheel
Connecting rod drives swing arm motion, and drives push rod to operate back and forth using swing arm, and when push rod is stuck, push rod can be with the movement of swing arm
It is detached from, so as to avoid generating damage to each component.
Its purpose is realized by following scheme:
A kind of bag pulling mechanism of soft material, motor-driven rotatable shaft band movable eccentric wheel rotate, and eccentric wheel passes through first connecting rod
Swing arm is driven to swing, its main feature is that, swing arm free end drives drive seat back and forth to operate by second connecting rod, and connection is fixed on push rod
Dynamic seat, and strong magnet is installed in drive seat or linkage seat, drive seat and linkage seat are attached together by strong magnet.
In this way, in normal conditions, drive seat can drive linkage seat by strong magnet, and drive push rod fortune by linkage seat
Make；When colliding, which occurs, in push rod to get stuck, under the action of resistance, drive seat can separate push rod with linkage seat and push rod generation.
It is preferred that being equipped with overcurrent protection switch in drive seat or linkage seat in above scheme.When drive seat and linkage
When seat generates separation, overcurrent protection switch can monitor and provide alarm signal, can be shut down simultaneously according to the alarm signal
Audible signal is issued to prompt worker to carry out manual intervention.
The bag pulling mechanism of thus obtained soft material, when occur colliding get stuck when, since linkage seat and drive seat generate
Separation, then, push rod will run out of steam, and resistance is also no longer passed to swing arm, in addition, autostop and report can also be issued
It is alert.
The bag pulling mechanism of the soft material of the invention collides when getting stuck, and linkage seat is produced with drive seat and separated, by
Power is no longer obtained in push rod, thus protect the mechanism of push rod can, plays the hard defects for preventing transmission mechanism from may cause
Evil.
The bag pulling mechanism of the soft material of the utility model collides when getting stuck, and linkage seat is produced with drive seat and separated, by
It is also no longer passed to swing arm in resistance, thus makes swing arm and transmission mechanism also to be protected, playing prevents to swing arm and biography
The damage that motivation structure may cause.
The bag pulling mechanism of this soft material collides when getting stuck, and linkage seat is separated with drive seat once generating, and overload protection is opened
Pass just will monitor this case, and the signal generated will lead to machine down, to can provide practical peace for worker again
All risk insurance card.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of specific embodiment structure of the utility model；
Fig. 2 is the schematic diagram that the bag pulling mechanism of Fig. 1 soft material is overlooked；
Fig. 3 is the schematic diagram of drive seat in Fig. 1, strong magnet, linkage seat and pusher structure；
Fig. 4 is that Fig. 3 gets stuck the schematic diagram that drive seat under state separates with linkage seat.
Specific embodiment
Specific embodiment of the present invention is described in detail with reference to the accompanying drawing:
Referring to Figures 1 and 2, the bag pulling mechanism of the soft material of present embodiment, including motor 14, shaft 15, partially
Heart wheel 13, first connecting rod 12, swing arm 11, second connecting rod 1, guide rail 7, drive seat 4, strong magnet 3, linkage seat 2, overcurrent protection switch
5 and push rod 6, wherein 14 drive shaft 15 of motor is rotated with movable eccentric wheel 13, and eccentric wheel 13 is by first connecting rod 12 with movable pendulum
Arm 11 is swung, and 11 free end of swing arm drives drive seat 4 back and forth to operate on guide rail 7 by second connecting rod 1, is fixed on push rod 6
Linkage seat 2, and strong magnet 3 is installed in drive seat 4, drive seat 4 is attached together with linkage seat 2 by strong magnet 3, drive seat
Overcurrent protection switch 5 is also equipped on 4.
Referring to Fig. 3, in the case where nominal situation, drive seat 4 can drive linkage seat 2 by strong magnet 3, and by linkage seat
2 drive 6 normal operation of push rod.
Referring to Fig. 4, when colliding, which occurs, in push rod to get stuck, resistance suffered by push rod 6 is greater than the magnetic force of strong magnet 3, then, driving
Seat 4 can separate under the drive of second connecting rod 1 with linkage seat 2, at this point, overcurrent protection switch 5 will monitor this case, mention to machine
For signal, machine can be allowed to shut down rapidly and issue audible alarm.
