Description

Technical Field

[0001] The invention belongs to the technical field of edge inserting machines, and in particular relates to an edge inserting machine unit capable of automatically replenishing and releasing air. Background Art

[0002] In the edge inserting unit, a continuously transported film bubble structure will be formed between the rubber roller and the triangular bucket. The connection between the film bubble and the rubber roller forms a cone-shaped transition section with a narrow upper strip and a cylindrical lower part. If the pressure inside the film bubble changes, that is, the amount of gas is too much or too little, it will affect the working efficiency and effect of the edge inserting machine, thereby affecting the subsequent packaging film transportation and edge inserting processes.

[0003] Now, the distance between the transition section and the film can be detected by a distance measuring mechanism such as an ultrasonic sensor, so as to detect whether the transition section has collapsed or over-expanded problems, and thus adjust the internal air pressure. If an ultrasonic sensor is used for detection, the detection accuracy will be poor, and the vibration will be greatly affected. The ordinary contact detection mechanism is not suitable for continuous bubble transportation, which affects the pressure control accuracy.

[0004] Therefore, designing a side inserting machine unit that can automatically replenish and release air and accurately detect is a problem that needs to be solved by workers in this field. Summary of the Invention

The roller group structure driven by the screw mechanism can realize the lifting and lowering adjustment of the roller group. The length of the film bubble can be adjusted by adjusting the distance between the roller group and the triangular bucket. When the amount of gas in the film bubble remains unchanged, the pressure can be adjusted within a certain range. The detection accuracy is high and the response is fast, thereby realizing the automatic replenishment and release of air of the side-insertion unit.
