Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment discloses an unwinding mechanism for an unwinding frame, as shown in fig. 1 and 3, the unwinding mechanism comprises an unwinding frame rack 1 and an inflatable shaft 4, a support shaft 2 is arranged on the unwinding frame rack 1, a rotatable support shaft 2 is arranged on the unwinding frame rack 1, a pair of sliding plates 3 are symmetrically arranged on the side wall of the support shaft 2, sliding guide rails 21 are arranged on the support plate along the length direction of the support shaft 2, the sliding plates 3 are slidably arranged on the sliding guide rails 21, the cylinder assembly comprises piston rods 32 which are close to each other and extend, one ends of the piston rods 32, which are far away from the cylinder assembly, are fixed with fixed blocks 321, and the other ends of the fixed blocks 32 are fixed on the side wall of the support shaft 2. Can drive the sliding plate 3 through mechanism control back shaft 2 rotation and rotate to drive fixed plate 31 on the sliding plate 3 and rotate, on the both ends of physiosis axle 4 were fixed in fixed plate 31, along with the rotation of fixed plate 31, thereby change the height of physiosis axle 4, operate with the high demand of reply difference.

The end that the sliding plate 3 kept away from each other extends perpendicularly to the front end and is provided with fixed plate 31, be equipped with fixed orifices 311 on the fixed plate 31, the both ends of physiosis axle 4 are scalable and rotate and peg graft in fixed orifices 311, the tip of physiosis axle 4 is equipped with the bellying 42 that the cross-section is square, the cover is equipped with axle sleeve 6 on the bellying 42, axle sleeve 6 is rotatable for fixed orifices 311.

In this embodiment, as shown in fig. 2, a support block 5 is disposed below the inflatable shaft 4 on the inner side of the sliding plate 3, a notch 51 is disposed on one side of the top of the support block 5 close to the sliding plate 3, an annular protrusion 41 is disposed on the sidewall of the inflatable shaft 4, and the lowest point of the annular protrusion 41 is higher than the highest point of the notch 51. The side of the support block 5 remote from the slide plate 3 is provided with a bearing 52, and the bearing 52 is in rotational abutment with the side wall of the inflatable shaft 4.
