The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0023] A friction disc type bracket conveying mechanism, such as Figures 1 to 3 As shown, it includes a sprocket shaft 1, a sprocket 2, a meshing conveying chain 3, an inner support chain 4, a bracket 5, a guide positioning block 6, and a clamping friction disc assembly 7.

[0024] Two sprockets 2 are installed on the sprocket shaft 1, and the sprockets 2 are connected to the sprocket shaft 1 through a key.

[0025] A meshing conveying chain 3 is wound around each sprocket 2, an inner supporting chain 4 is extended and fixed inside the meshing conveying chain 3, and a plurality of brackets 5 are installed on the inner supporting chains 4 on both sides along the conveying direction.

[0026] The bracket 5 includes a support plate 51 , and L-shaped hanging plates 52 are symmetrically provided on both sides of the bottom of the support plate 51 . The inner support chain 4 is located between the bottom of the support plate 51 and the horizontal plate of the L-shaped hanging plate 52 .

[0027] When the support plate 51 is transported upward, it contacts the inner support chain 4 by its own weight. When the support plate 51 is transported downward, it is hung on the inner support chain 4 by the L-shaped hanging plate 52 and will not fall.

[0028] L-shaped ribs 53 are mounted on both left and right ends of the front side surface and left and right ends of the rear side wall of the support plate 51 by bolts.

[0029] A guide positioning block 6 is fixed at the middle position of the bottom of the bracket 5, and the guide positioning block 6 is mainly used to realize the positioning and steering of the bracket 5 at the turning point.

[0030] The guide positioning block 6 is clamped at the bottom of the positioning groove of the support plate 51 and is detachably mounted on the support plate 51 by bolts, so that it is convenient to disassemble and replace.

[0031] A U-shaped groove is provided on the top of the guide positioning block 6 and the U-shaped groove is clamped in the positioning groove of the support plate 51, which is more stable.

[0032] A clamping friction disc assembly 7 is installed on the sprocket shaft 1 at the middle position of the two sprockets 2. The arrangement of the clamping friction disc assembly 7 is mainly to help the bracket 5 to achieve positioning and steering at a turning point.

[0033] The clamping friction disc assembly 7 includes a stepped shaft 71 arranged on the sprocket shaft 1, and a clamping plate 72, a backing plate 73, a butterfly spring 74, a washer 75, a stop washer 76 and a round nut 77 are symmetrically installed on both sides of the stepped shaft 71; the guide positioning block 6 is located between the two clamping plates 72 of the clamping friction disc assembly 7.

[0034] The working principle of the utility model is:

[0035] When the bracket 5 is transported upward, it sticks to the inner support chain 4 under the action of its own gravity. When the bracket 5 moves from top to bottom or from bottom to top (i.e. turning), the bowl-shaped butterfly spring 74 is adjusted to a suitable deformation amount by adjusting the round nut 77 to ensure that the guide positioning block 6 can be stuck between the two clamping plates 72 during the movement, and the clamping force generated by the deformation is used to transport the bracket 5 to turn. At the same time, it is ensured that after the bracket 5 completes the rotation, it can overcome the clamping force between the two clamping plates 72 under the sliding friction of the meshing conveying chain 3 and the inner support chain 4, and achieve smooth separation.

[0036] The utility model reduces the power source and saves the cost; the adjustment method is more flexible and the potential safety hazard in the process of loading and unloading materials is reduced; and the feeding method is simplified.

[0037] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
