Description

Technical Field

[0001] The utility model relates to the technical field of coating composite equipment, in particular to a composite interlayer bubble control and elimination system. Background Art

[0002] At present, during the operation of the existing solvent-free film composite equipment, due to poor equipment debugging or other problems, each composite will cause bubbles to be generated between the composite layers. If the bubbles are not processed, the bubbles will be squeezed and moved by the composite roller when the composite film enters the next composite roller, and the bubbles will gather and increase in volume, and the two layers of the composite film will be separated and then pass through the composite roller, which will eventually cause a large section of the composite film to have wrinkles, bubbles or partial separation of the film, thereby greatly affecting the quality of the finished product of the solvent-free film composite. The method of eliminating bubbles used in the solvent-free film composite exhaust machine is usually that the worker sees the bubbles before the final winding of the composite multi-layer, and presses the corresponding button switch, so that the mechanical multi-head blade makes a longitudinal cut on the film at a certain width dimension to make a surface cut on the material position where bubbles may be generated; however, since the time for the blade to cut the composite film can only be controlled manually, the crack of the processed film is large, and the next process is prone to failure points.

[0016] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be through bolt fixing or pin fixing, or pin shaft connection and the like commonly used in the prior art, and therefore, it will not be described in detail in this embodiment.

[0018] The main film 1 and the secondary film 2 coated with glue are compounded at the compounding component 6 to form a composite film 9. After the composite film 9 is subjected to bubble detection, puncture and marking by the bubble elimination unit 7, it continues to be compounded or rolled onto the winding component 8 to complete the compounding; the bubbles are detected by the bubble elimination unit 7 to determine whether there are bubbles and the position of the bubbles on the film, and then the bubbles are punctured by driving the puncture device, so that the bubbles are connected to the atmosphere and the internal gas is discharged to achieve bubble elimination, so that there are no bubbles in the composite film 9 during the next compounding or winding, thereby ensuring the smooth progress of the multi-layer compounding and the production quality of the composite film 9; and the punctured part of the composite film 9 is regarded as waste film, which is marked to facilitate the subsequent removal of the waste film according to the mark.

[0019] The main film 1 is a composite film 9 from which bubbles have been eliminated or a single-layer film rolled up on the first unwinding component 3, and the secondary film 2 is a single-layer film rolled up on the second unwinding component 4 and glued by the gluing coating component 5; in a single or multiple composite processes, bubbles may be generated in the composite film 9 due to poor equipment debugging, uneven force on the composite film 9 and other problems, so a group of bubble elimination units 7 are correspondingly set up for each composite to perform bubble elimination processing.

[0020] Preferably, the bubble elimination unit 7 includes a bubble detection device 71, a bubble puncture device 72 and a coding identification component 73 which are sequentially arranged along the advancing direction of the composite film 9, and are used to correspondingly realize the bubble detection, puncture and identification actions, thereby eliminating the bubbles;

[0021] Preferably, the bubble detection device 71 includes a visual detection device, which continuously performs visual detection on the composite film 9 in a direction perpendicular to the composite film 9, finds bubbles by finding a preset grayscale value in the captured image, and determines information such as the size and position coordinates of the bubbles; finally, the bubble information is transmitted to the bubble puncturing device 72 and the coding marking component 73, so that the bubble is punctured by the bubble puncturing device 72, and then the punctured composite film 9 portion is coded by the coding marking component 73. In this embodiment, the coding marking component 73 will mark the width edge of the composite film 9 where the coding marking component 73 is sprayed.

[0022] Preferably, the bubble puncture device 72 includes one or more of a pneumatic multi-blade bubble puncture device 721, a needle roller bubble puncture device 722, and a high-pressure air knife bubble puncture device 723, which are used in combination; when multiple bubble puncture devices 72 are used at the same time, the accuracy of bubble puncture can be improved to avoid missing bubbles that are not punctured. Among them, the pneumatic multi-blade bubble puncture device 721, the needle roller bubble puncture device 722, and the high-pressure air knife bubble puncture are all existing technologies, so they are not described in detail in this application.

[0023] Preferably, the second unwinding assembly 4 and the gluing and coating assembly 5 are arranged in pairs, and several groups are arranged correspondingly according to the number of composite layers; the single-layer films rolled on each of the second unwinding assemblies 4 are different, and can be adjusted accordingly according to production requirements.

[0024] Preferably, the glue coating assembly 5 includes one of a blade coating and a five-roll coating.

[0025] The technical effects of the utility model are mainly reflected in: detecting bubbles through the bubble elimination unit to determine whether there are bubbles and the position of the bubbles on the film, and then driving the puncture device to puncture the bubbles, so that the bubbles are connected to the atmosphere and the internal gas is discharged, thereby achieving bubble elimination, so that there are no bubbles between the composite film layers during the next compounding or winding, ensuring the smooth progress of multi-layer compounding and improving the production quality of the composite film; and the punctured part of the composite film is regarded as waste film, which is marked to facilitate the subsequent removal of the waste film according to the mark.

[0026] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations.
