The whole power of the sealing cutter comes from the rocker arm connecting rod at the lowest end, and when the connecting rod moves downwards, the cylindrical connecting pull rod is driven to move downwards; the locking nut at the upper end of the cylindrical connecting pull rod compresses the upper end spring to enable the upper sealing cutter frame to be pressed downwards, and at the moment, the upper sealing cutter and the lower sealing cutter are sealed. When the upper sealing knife and the lower sealing knife are sealed, the lower end limiting nut in the cylindrical connecting pull rod can compress the lower end spring, so that the upper sealing knife generates upward elastic force to balance the sealing pressure of the sealing knife. When the rocker connecting rod is reset upwards, the cylindrical connecting pull rod is driven by the rocker connecting rod to move upwards, and the compressed lower end spring and the compressed upper end spring are released simultaneously, so that the upper sealing knife and the lower sealing knife are separated. In the whole series of processes, the pressure of the sealing knife is completely determined by the stretching elastic force of the spring, however, the pressure of the spring has no data for process recording. The motion principle of the sealing knife of the traditional bag making machine is roughly the same.
In the long-term production process of the sealing knife set of the traditional bag making machine, a gap exists between the cylindrical connecting pull rod and the wear-resistant copper sleeve due to certain abrasion caused by mutual friction, so that the verticality of the upper sealing knife and the lower sealing knife is not enough, and small dislocation occurs; the upper sealing knife and the lower sealing knife are difficult to keep mutually aligned during sealing, so that the sealing edge is widened or the virtual sealing is overlarge, and the quality of a finished packaging bag is unstable.

The field bus of the bag making machine adopts a field bus module produced by German Beifu to connect all the servo motors, and utilizes advanced bus control to synchronously transmit control information numbers to each transmission control point, thereby bringing higher precision and product stability.
When equipment runs, when finding that the heat sealing strength of a certain position on a finished product packaging bag is abnormal, a worker can judge which sealing mechanism is abnormal in pressure through the numerical value of each barometer, and the heat sealing strength is abnormal. And the air pressure regulating valve is used for regulating the pressure of each air cylinder 10021 so as to restore the pressure balance of the sealing mechanism, so that the heat sealing strength of the product is consistent. Compared with a debugging method that the spring pressure can be adjusted by loosening and tightening a limit nut or a locking nut for many times in a traditional machine type, the method needs to be simple, convenient and rapid.
In addition, the sealing time length of each sealing mechanism can be controlled by the positive and negative rotation and the speed and the matching of the servo motor and the cam, and the requirements of different products on different heat sealing effects of each sealing mechanism are met. This is incomparable to traditional model, because all sealing mechanisms of traditional model all carry out power series connection through the rocking arm connecting rod of main motor, can't control the sealing time of each sealing mechanism alone, can only unify the adjustment, can't satisfy various heat-seal demands.
For example, when the bag body is too long and needs to be subjected to double feeding and heat sealing, a worker can set a servo motor through an external industrial PC; one or certain sealing mechanism does not carry out sealing action, and other sealing mechanisms carry out normal sealing, so that the requirement of double heat sealing is met. Or because some special materials and special bag types need the lengthening of the heat-sealing time of a certain sealing mechanism, when the heat-sealing time of other sealing mechanisms is not changed, workers can also set the servo motor through an external industrial PC; the servo motor of a certain sealing mechanism is accelerated before sealing, the motion speed of the sealing mechanism is increased, and the servo motor is decelerated during sealing and the motion speed of the sealing mechanism is reduced; the motor speed of other servo motors is slowed down before sealing, the motion speed of the sealing mechanism is slowed down, the motor speed is unchanged during sealing, and the sealing time of the sealing mechanism is unchanged; the servo motor can meet various speed requirements of production through a series of editing settings.
Example 2
As shown in fig. 12 and 13, the bag machine in the present embodiment is different from embodiment 1 in that:
the upper sealing driving unit 1002 is a second servo driving unit, the second servo driving unit includes a second servo motor 10022, a second synchronous belt transmission mechanism 10023 (composed of a second synchronous transmission belt and two second pulleys), a second transmission shaft 10025, two second cams 10026, and two second swing arms 10027, the second servo motor 10022 is installed in the middle of the top end of the second frame 1005, and four second transmission shaft fixing frames 10024 are installed on the inner side of the top end of the second frame 1005; install second transmission shaft 10025 on four second transmission shaft mounts 10024, second servo motor 10022 connects second transmission shaft 10025 through synchronous belt drive mechanism 10023 of second, and two second cams 10026 are installed respectively at the both ends of second transmission shaft 10025, and two second swing arms 10027 bottom articulate two second cams 10026 respectively, and two second swing arms 10027 top articulate respectively and seal knife rest 10011. Second servo motor 10022 drives the rotation of second transmission shaft 10025 through second synchronous belt drive mechanism 10023, and two second cams 10026 rotate along with second transmission shaft 10025 to two second cams 10026 drive the motion of corresponding second swing arm 10027 respectively, thereby drive and seal up the lift of knife rest 10011.
The top end of the second swing arm 10027 is offset from the center of the second cam 10026 at the connection with the second cam 10026.
Because this embodiment uses two servo sealing sword structures, can pass through bus module control upper and lower involution drive unit in servo motor's rotational speed difference, make the sealing sword in upper and lower involution unit have fixed clearance during each involution, this clearance then is the thickness size of finished product wrapping bag heat seal limit. For example, when the distance from the center of the link of the top end of the second swing arm 10027 and the second cam 10026 to the center of the second cam 10026 is 20mm, at a suitable temperature, the rotating speed difference of the servo motor in the upper and lower sealing driving units is controlled to be 1 ℃ by the summary module, a gap fixed to be 0.1mm exists between the upper and lower sealing units during each sealing, when a finished packaging bag is sealed, the sealing thickness can be fixed to be 0.1mm, and the heat sealing strength is more stable.
In addition, it should be noted that the names of the parts and the like of the embodiments described in the present specification may be different, and all the equivalent or simple changes made according to the structure, the features and the principle of the present invention are included in the protection scope of the present invention.
