A continuous sealing machine for plastic film

Abstract

This utility model relates to the technical field of continuous plastic film sealing machines, and discloses a continuous plastic film sealing machine including a mechanism mounting body. The mechanism mounting body has a drive chamber inside, and a drive motor is installed inside the drive chamber. In this utility model, the drive motor drives a transmission shaft to rotate via a transmission mechanism, and the transmission shaft drives a front roller to rotate. When the front roller rotates, it drives a film conveyor belt to rotate around the front and rear rollers. The rotation of the film conveyor belt moves the external plastic film bag. During operation, the sealing mechanism moves the upper half of the plastic film bag and seals it. Driven by the transmission mechanism, the conveying mechanism moves the lower half of the plastic film bag and the upper half of the plastic film, effectively preventing the upper half of the plastic film bag from falling out of the sealing mechanism during the sealing process.

The drive motor 3 can drive the conveying mechanism 7 to move the plastic film through the transmission mechanism 4.

[0017] During operation, the end of the plastic film bag to be sealed is first placed inside the sealing mechanism 6, and then the plastic film bag is placed on the conveying mechanism 7. During operation, the drive motor 3 drives the sealing mechanism 6 to rotate through the transmission mechanism 4. When the sealing mechanism 6 rotates, it can move the upper part of the plastic film bag. When the sealing mechanism 6 moves the upper part of the plastic film bag, it can seal the plastic film bag. During the sealing process, the drive motor 3 drives the conveying mechanism 7 to rotate through the transmission mechanism 4. When the conveying mechanism 7 rotates, it can move the plastic film bag. During the sealing process, the plastic film bag can move synchronously with the sealing part, which can effectively prevent the plastic film bag from falling out of the sealing mechanism 6 during the sealing process and affecting the sealing effect.

[0018] Please see Figure 1 - Figure 6As shown, the sealing mechanism 6 includes an upper power roller 61 and a lower power roller 64.

When sealing the plastic film, the sealing point of the plastic film bag is sandwiched between the upper conveyor belt 63 and the lower conveyor belt 66. When the upper conveyor belt 63 and the lower conveyor belt 66 rotate, they can drive the sealing point of the plastic film bag to move. When the plastic film bag moves, the sealing heating block 69 can heat the plastic film. The sealing area of ​​the plastic film bag is heated. When the sealing roller 610 moves inside the sealing area of ​​the plastic film bag, the sealing roller 610 can squeeze and seal the sealing area of ​​the plastic film bag. After sealing, the upper conveyor belt 63 and the lower conveyor belt 66 continue to drive the plastic film bag to move.
