Description

Technical Field

[0002] Currently, the venting method used in existing solvent-free film composite venting machines and equipment typically uses a blade to longitudinally score the film at a certain width dimension to create a surface notch at the material where bubbles may form. This method has the following disadvantages: the lateral position of the bubble removal is fixed and cannot be adjusted; although lateral adjustment is possible, it must be made before the machine is started and cannot be adjusted online; its intermittent passive principle structure affects local tension during use; the film joint position is not tracked and can only be controlled manually; the processed film has large cracks, which easily lead to failure points in the subsequent process; the existing composite pressure instant lifting technology for venting has the following disadvantages: the composite speed is used as the reference speed in the equipment control, and once the composite pressure rollers are released from pressure, the tension system of the entire machine is disturbed; in multi-layer composite equipment, the distance between the multiple composite rollers is short. If they need to be lifted one by one, a stable tension barrier cannot be formed within a certain section, which means that normal operation cannot be completed, and the venting function cannot be effectively performed.

A method for controlling a piercing and exhausting bubble blocking device according to claim 5, characterized in that: S400, including: S401, based on the position reached by the film joint during operation, the exhaust device is controlled to start the exhaust action; based on the film composite exhaust requirements, the film composite exhaust mode control signal is intelligently selected; the film composite exhaust requirements include: film composite single-point exhaust requirements and film composite multi-point exhaust requirements; the film composite single-point exhaust requirements correspond to the film composite single-point exhaust mode; the film composite multi-point exhaust requirements correspond to the film composite multi-point exhaust mode; the film composite exhaust mode control signal is intelligently selected, including: single-point setting control signal and multi-point setting control signal; S402, according to the single-point setting exhaust mode of the film composite, only the first exhaust device is set at a single point, and the single-point setting control is performed according to the single-point setting control signal, so that bubbles and transfer bubbles are generated at the joint of the multi-roll unwinding film, and bubble removal and bubble transfer prevention control are performed on the first exhaust device in sequence according to the exhaust process sequence; transfer bubbles are bubbles that are transferred from the film joint to the composite layer of the film during the film composite process; The single-point setting control includes: performing signal control according to the position setting of the single-point exhaust device, generating bubbles and bubble transfer areas for all unwinding film joints, and performing single-point setting control according to the preset distance calculation result, when all film joint areas pass through the single-point exhaust device, or when the position area corresponding to the material to be composited passes through the single-point exhaust device, completing the film puncture by controlling the single-point exhaust device, so that the bubbles contained in the film joint are discharged from the composite film puncture hole, thereby performing bubble removal and bubble transfer prevention control; S403, according to the composite multi-point exhaust mode of the film, multi-point setting control is performed to synchronously remove bubbles and prevent bubble transfer for multiple rolls of unwinding film, and synchronously track and control the exhaust of bubbles generated and transferred at all film joints; The multi-point setting control includes: performing signal control according to the multi-point exhaust device setting, generating bubbles and bubble transfer areas for all unwinding film joints, and performing multi-point control according to the film joint distance calculation result. When the film joint passes through the exhaust device, or when the film layer to be compounded with the film joint passes through the exhaust device, the corresponding exhaust device is started to complete the film puncture, so that the air contained in the film joint is discharged from the film puncture hole, and bubble removal and bubble transfer prevention control are performed.
