Description

[0028] Working principle: First, the large roll of curtain cloth and the large roll of film are placed on the unwinding mechanism 4 respectively, and then the drive of the unwinding mechanism 4 is started and the curtain cloth or film is unwound and transported along the first feeding platform 51 of the fixed-length feeding mechanism 5. During the transportation process, if the curtain cloth or film is offset, the curtain cloth is detected by the offset detection mechanism provided on the curtain cutting mechanism 52 to see whether it is offset. In the event of offset, the controller controls the start of the first driving mechanism according to the specific angle of the detected offset. The first driving mechanism drives the cutting frame to rotate the angle of the curtain cloth offset along the rotating table 511, so that the cut curtain cloth can meet the specification requirements. If the cut curtain cloth is offset again on the first feeding platform 51, since the curtain feeding mechanism 58 is relatively arranged to the first feeding platform 51, when the curtain cloth is on the curtain feeding platform 58 and is ready to be placed on the conveying platform, the curtain cloth position detector provided on the mounting plate 54 will detect the offset position of the curtain cloth. At this time, the controller controls the start of the third driving mechanism, and the curtain feeding mechanism 58 It can rotate relative to the mounting plate 54 so that when the curtain is placed on the conveying platform 1, it meets the specification requirements to ensure the subsequent standardization of bonding. If the film is offset, the fifth drive mechanism, the correction fork and the position detector arranged on the correction fork provided on the guide mechanism 4 will be used to judge the distance of the film offset. After the position detector detects the data, the controller controls the fifth drive mechanism, and its output end can push the guide mechanism 4 to slide left or right along the fixed plate, so that the film is placed in the standard position before cutting. After the film is cut by the cutting mechanism, it is transported to the conveying platform 1 by the film feeding platform 510 through the fourth drive mechanism. When the four curtains and films are placed on the conveying platform 1 according to their positions, the bonding molding machine 2 and the conveying platform 1 drive structure are started at the same time, and the bonding molding machine 2 can bond the four curtains and films together to form an air spring barrel, and then the two arc-shaped clamps of the clamping mechanism 6 cooperate with the second bidirectional screw and the lifting assembly to clamp the air spring (commercial) barrel to the embryo molding machine for reverse packaging.

[0029] In addition, the above working principle describes the production of commercial air springs; when producing passenger air springs, the barrel can be directly removed from the laminating and molding machine 2 after it is produced.
