Detailed Description

The detailed description of the present invention is provided with reference to fig. 1 and 2.

With reference to fig. 1 and 2, the roller guide roller for carbon fibers comprises a roller shaft head 1, a roller shaft core 2, a roller 3 and a detachable sealing assembly, wherein the roller shaft head 1 is arranged at two symmetrical sides of the roller shaft core 2; the roller 3 is sleeved on the roller shaft core 2, and two ends of the roller are fixed with the roller shaft head 1. Can dismantle seal assembly sets up in roller spindle nose 1's the outside, from inside to outside in proper order for bearing 5, bearing stop collar 7, sealed piece 8 and axle sleeve 9 to constitute, bearing 5 covers on roller spindle nose 2, and bearing stop collar 7 is fixed in the bearing 5 outside, axle sleeve 9 and roller spindle nose 1 tip fixed connection are connected with bearing stop collar 7 and sealed piece simultaneously, sealed piece be located axle sleeve 9 with between the roller spindle nose 2.

The roller shaft head 1 and the roller shaft core 2 are sealed through a first trapezoid sealing ring 6.

The roller surface 4 is wrapped outside the roller 3, the roller 3 and the roller surface 4 are detachably connected, and the roller surface 4 is made of rubber or ceramic.

Furthermore, a plurality of uniformly distributed bosses 14 are arranged on the outer surface of the roller 3, and limiting grooves are symmetrically arranged at two ends of the roller; the inner surface of the roller surface 4 is provided with a plurality of grooves matched with the bosses 14. The roller surface 4 is nested on the lug boss of the roller 3 through the groove, the two ends of the roller 3 are symmetrically provided with the limiting grooves 5, and the two ends are firmly limited and fixed by the fasteners and the limiting grooves; the boss 14 of the roller 3 forms an included angle of 0-45 degrees with the rotating direction Q of the roller guide roller (the tangent line at the boss 14), when the roller is replaced, fasteners at two ends are loosened, the worn roller surface 4 is drawn out from one side of the roller guide roller 3, a new roller surface 4 is sleeved into the roller along the boss 14 to replace the roller, and the replacement of the new roller guide roller is finished.

The inner side of the bearing 5 abuts against the outer side of the roller shaft head 1, and the outer side of the bearing 5 is embedded into a fixed position through the bearing limiting sleeve 7.

The shaft sleeve 9 is fixedly connected with the roller shaft head 1 through a plurality of uniformly distributed fasteners 11, and metal O-shaped sealing rings 10 are arranged on the inner sides of the fasteners 11.

A boss-shaped sealing block 8 is arranged between the shaft sleeve 9 and the roller shaft core 2.
