Tail chain tensioning device of a flat and grooved sorting machine

Abstract

The utility model provides shallow slot sorting machine tail chain tensioner, relate to tensioner technical field, including the casing, the inside symmetry fixed connection of casing has the guide rod, the outside slide connection of guide rod has the sliding block, the top fixed connection of sliding block has the top block, the back of casing is equipped with the adjusting mechanism, the adjusting mechanism includes sleeve, threaded sleeve, second screw rod and connecting block, the back of casing is equipped with sleeve, the bottom end rotationally connected of sleeve has threaded sleeve, the utility model discloses the up and down reciprocating of second screw rod can be driven through the positive and negative rotation of threaded sleeve simultaneously, no. The fixed plate is fixed as an organic whole through bolt with casing, so that the bottom of second screw rod is connected with casing, is used to drive the lifting movement of casing, so that the top of top block and the outside of chain are attached and chain is tensioned, so as to solve the problem of frequent replacement caused by stress deformation elongation in the prior art.
