Description

Technical Field

[0002] The gluing machine is a device that can process the surface of fabrics (cotton fiber, glass fiber, carbon fiber, polyester fiber, etc.) with glue. During the gluing process, due to the long production stroke and the uneven tension of the fiber substrate itself, it is easy to cause uneven local gluing in production, resulting in uneven thickness of the prepreg produced during pressing or warping and deflection due to uneven local tension. To address such problems, we proposed a gluing tension adjustment device for prepreg. Utility Model Content

The tension adjustment mechanism A81 and the tension adjustment mechanism B82 have the same structure, and the tension adjustment mechanism A81 on the front side can perform preliminary tension adjustment on the cloth. Section, the tension adjustment mechanism A81 and the tension adjustment mechanism B82 are respectively placed on both sides of the gluing machine 5, and a traction roller 7 is arranged on the end of the support frame 1 away from the material frame 2. The traction roller 7 is placed above the tension adjustment mechanism B82. Through the cooperation of the two, the raw material 3 is pulled and the cloth is advanced. The tension adjustment mechanism B82 includes a horizontal plate 9 spanning the inner side of the support frame 1 and other structures on the surface of the horizontal plate 9. Support seats 10 are evenly arranged on the surface of the horizontal plate 9. A lifting rod 12 is vertically slidably installed on the top of the support seat 10. An adjusting roller 13 is rotatably installed on the top of the lifting rod 12. The adjusting roller 13 is parallel to the axis of the traction roller 7. The raw material 3 runs through between the adjusting roller 13 and the traction roller 7. The distance between the individual adjusting roller 13 and the traction roller 7 is controlled by controlling the lifting rod 12 to achieve adjustment of the local tension.

[0020] Please refer to Figure 3 and Figure 4As shown, a longitudinal slide 14 is provided on the upper surface of the support seat 10, and the bottom of the lifting rod 12 slides on the inner side of the longitudinal slide 14, so that the lifting rod 12 can only slide in the vertical direction. An annular boss 15 is provided on the inner side of the longitudinal slide 14, and the annular boss 15 is placed under the lifting rod 12. An extension rod 18 is provided at the bottom of the lifting rod 12, and the extension rod 18 passes through the annular boss 15.

The elastic force of the spring 21 is used to make the mounting head 19 always have a downward force, so that the roller 20 at the bottom is always in contact with the upper inclined surface of the inclined push block 17.

[0021] Among them, cylinders 11 are evenly arranged on one side of the horizontal plate 9. The cylinder 11 placed on one side of the support seat 10 is convenient for installation and observation.

The relative position of the oblique push block 17 can be controlled by the cylinder 11, and then the height of the installation head 19 is controlled by the inclined surface of the oblique push block 17. At the same time, due to the elastic force of the spring 21, the installation head 19 always has a downward force, and then the roller 20 always keeps in contact with the inclined surface of the oblique push block 17, so as to realize the pulling of the cloth through the rotation of the traction roller 7. Before entering the gluing machine 5, the cloth is subjected to preliminary tension adjustment by the tension adjustment mechanism A81, and is glued by the gluing machine 5 and dried by the dryer 6, and then enters the cutting area. When the local tension is insufficient, the position of the oblique push block 17 can be controlled to realize the adjustment of the height of a single adjustment roller 13, so as to realize the adjustment of the local tension.
