Upwards, support then is being provided for sealing knife frame by upper spring in cylindrical connecting rod, lower spring.And the entirety of sealing knife is dynamic
Power is from the lowermost rocker-arm link, when connecting rod moves down, cylindrical connecting rod is driven to move down；Cylinder is even
The locking nut of pull rod upper end is connect by upper end spring-compressed, is pressed downward sealing knife frame, at this time upper sealing knife, the sealing of lower sealing knife.When
When upper sealing knife, the sealing of lower sealing knife, lower end stop nut in cylindrical connecting rod can be by lower end spring-compressed, sealing knife production in orders
Raw upward elastic force, the pressure of sealing knife sealing is balanced with this.When rocker-arm link resets upwards, cylindrical connecting rod is in rocker arm
It is also moved up under the drive of connecting rod, while discharging compressed lower end spring and upper end spring, separate upper and lower sealing knife.Whole
In a serial procedures, the pressure of sealing knife is determined by the stretching elasticity of spring completely, however the pressure of spring do not have data for
Carry out technique record.That's about the size of it for the sealing knife motion principle of traditional Bag Making Machine.
For the sealing knife group of traditional Bag Making Machine in permanent production process, cylindrical connecting rod can be because mutually rubbing with wear-resisting copper sheathing
Wiping causes centainly to wear and there are gaps, therefore it is inadequate to will appear sealing knife verticality up and down, small dislocation occurs；Make sealing knife up and down
It is difficult to keep and is mutually aligned in sealing, cause that edge sealing broadens or empty envelope is excessive, lead to finished product packing bag unstable quality.

The Bag Making Machine of the present embodiment 1 be applicable in it is hand-made make common three edge sealing bag, zippered bag, four edge sealing bags, middle envelope stereoscopic bag is different
Type self-standing bag, open self-standing bag, the self-standing bags such as band mouth self-standing bag.The scene that the fieldbus of Bag Making Machine is produced using Germany times good fortune
Bus module couples all servo motors, will control information synchronous transfer to each using advanced bus marco
It is driven control point, brings higher accuracy and product stability.
When equipment operation, when finding the heat seal strength exception of some position in finished product packing bag, worker can be by each
Air gauge numerical value judges the appearance of abnormal pressure of which sealing mechanism, causes heat seal strength abnormal.And with air pressure regulator to each
A cylinder 10021 carries out pressure adjustment keeps the heat seal strength of product consistent to restore the pressure balance of sealing mechanism.Comparison passes
System type needs repeatedly elastic stop nut or locking nut that could adjust the adjustment method of spring pressure, simple, convenient and fast
Very much.
In addition, by the positive and negative rotation of servo motor, speed speed and its with the cooperation of cam, can control each sealing mechanism
Sealing time length, demands of the reply different product to the different heat-sealing effects of each sealing mechanism.This is that conventional types can not
Analogy, because all sealing mechanisms of conventional types are all to carry out power series connection, Wu Fadan by the rocker-arm link of main motor
The sealing time of each sealing mechanism is solely controlled, can only unify to adjust, be unable to satisfy various heat-sealing demands.
Such as when bag body is too long, needs to be sent heat-sealing again, worker can be by external Industrial PC to servo motor
It is configured；Make some or certain to a sealing mechanism without sealing action, other sealing mechanisms normally seal, to reach times
Send the demand of heat-sealing.Or because certain special materials, special pouch-type need the heat-sealing time of certain one of sealing mechanism to lengthen, other
When the heat-sealing time of sealing mechanism is constant, worker can also be configured servo motor by external Industrial PC；A certain envelope
The servo motor of mechanism is closed sealing front motor speed is accelerated, sealing mechanism movement velocity becomes faster, servo motor speed when sealing
Slow down, sealing mechanism movement velocity it is slack-off；And other servo motors sealing front motor speed slow down, sealing mechanism movement velocity
Slack-off, motor speed is constant when sealing, sealing mechanism sealing time is constant；Servo can be made electric by a series of editor setting
Machine meets the various speed requirements of production.
Embodiment 2
As shown in Figure 12,13, the Bag Making Machine in the present embodiment the difference from embodiment 1 is that:
The upper sealing driving unit 1002 is the second servo drive unit, which includes the second servo electricity
Machine 10022, the second synchronous belt drive mechanism 10023(by the second Synchronous Transmission belt and two the second belt pulley sets at),
Two 10026, two the second swing arms 10027 of the second cam of transmission shaft 10025, two, the second servo motor 10022 are mounted on second
1005 top middle portion of frame, 1005 top inner side of the second frame are set there are four second driving shaft fixed frame 10024；Four second biographies
Second driving shaft 10025 is installed, the second servo motor 10022 passes through the second synchronous belt drive on moving axis fixed frame 10024
Mechanism 10023 connects second driving shaft 10025, and two the second cams 10026 are separately mounted to the two of second driving shaft 10025
End, two 10027 bottom ends of the second swing arm are respectively articulated with two the second cams 10026, and two 10027 tops of the second swing arm are cut with scissors respectively
Connect sealing knife frame 10011.Second servo motor 10022 drives second driving shaft by the second synchronous belt drive mechanism 10023
10025 rotation, two the second cams 10026 follow second driving shaft 10025 to rotate, and two the second cams 10026 divide
Corresponding second swing arm 10027 is not driven to move, so that upper sealing knife frame 10011 be driven to go up and down.
Deviate the center of circle of the second cam 10026 with 10026 place of link of the second cam in second swing arm, 10027 top.
Since the present embodiment is using double servo sealing knife structures, upper and lower sealing driving unit can be controlled by bus module
There is fixed gap in the rotational speed difference of middle servo motor, the sealing knife sealed up and down in unit when making to seal every time, this gap is then
The thickness size of finished product packing bag hot edge seal.Such as when 10027 top of the second swing arm with the second cam 10026 to link place center inclined
When circle center distance from the second cam 10026 is 20mm, in the case where being suitble to temperature, by summarizing module control, sealing driving is single up and down
In member the rotational speed difference of servo motor be 1, then can be achieved every time sealing when up and down sealing unit in sealing knife exist be fixed as
The gap of 0.1mm, when sealing to finished product packing bag, seal edge thickness can then be fixed as 0.1mm, and heat seal strength is also more steady
It is fixed.
In addition, it should be noted that, the specific embodiments described in this specification, each section title etc. can not
Together, the equivalent or simple change that all structure, feature and principles described according to the invention patent design are done, is included in the present invention
In the protection scope of patent.Those skilled in the art can do described specific embodiment various each
The mode that the modify or supplement or adopt of sample is similar substitutes, and without departing from structure of the invention or surmounts the claims institute
The range of definition, is within the scope of protection of the invention.
