Description

Technical Field

[0001] The utility model belongs to the technical field of slitting machines, and particularly relates to a laminating mechanism for a rubber air spring cord fabric slitting machine. Background Technique

[0002] In the manufacturing process of rubber air springs, according to the sizes of different rubber air springs, the wide-width crown ply cord fabric needs to be slit into narrow-width crown ply cord fabrics with different required widths by a slitting machine. Since a certain amount of surplus materials will be generated on both sides of the wide-width crown ply cord fabric after slitting, there is usually no special treatment, and they are relatively scattered. Since the sizes of different air springs are different, the widths of the slit cord fabrics will also be different. Sometimes, the width of the surplus materials generated after slitting can reach more than 10 cm. Also, since the slitting is carried out on two layers of cord fabric simultaneously, the total width of the generated surplus materials reaches more than 20 cm. Directly treating them as waste will lead to extremely wasteful materials, thereby increasing costs and being unfavorable to the development of enterprises.

[0003] In view of this, the utility model provides a laminating mechanism that can laminate the surplus materials generated by slitting to form a new cord fabric suitable for manufacturing air springs, thereby avoiding material waste. The mechanism has a simple structure and is easy to operate. Summary of the Invention

The coiling mechanism 5 is arranged directly above the conveyor belt 4 of the slitter. On both sides of the top of the striping frame 31 of the slitter, there are vertically arranged frame-shaped mounting frames 111. Between the two mounting frames 111, there are two overlapping laminating rollers 112 rotatably arranged. Among them, the shaft of the upper laminating roller 112 is slidably arranged up and down on the two mounting frames 111 through the slider seat 113. On the top of the two slider seats 113, there are vertically arranged screws 114. The upper end of the screw 114 penetrates through the top of the mounting frame 111. A crank 115 is sleeved on the screw 114 at the top of the mounting frame 111. When adjusting the distance between the two laminating rollers 112, just shake the cranks 115 on both sides. On the slitter on the side away from the coiling mechanism 5 of the slitter, there is a cloth winding roller shaft, and the cloth winding roller shaft is driven by a driving mechanism.

[0020] Preferably, the coiling mechanism 5 includes a support 51 erected on the conveyor belt 4. On the support 51, there is a horizontally arranged padding cloth guide roller 52.

The distance between the two laminating rollers 112 is adjusted according to the thickness of the curtain fabric. When adjusting, turn the crank 115 to control the downward movement of the upper laminating roller 112. When the interval between the two laminating rollers 112 is appropriate, the two remaining materials in front of them are placed into it. When placing, the two remaining materials are placed between the two laminating rollers 112 in the way of overlapping at both sides. Then, the remaining materials laminated by the laminating rollers 112 are wound by the cloth winding roller shaft, and the driving mechanism is started to complete the lamination of the two remaining materials. The structure of this mechanism is simple and the operation is convenient. The remaining materials generated by slitting can be laminated to form a new curtain fabric for making air springs, thereby avoiding waste of materials.
