Floating type high-temperature non-metal roller way for microlite heating furnace

The invention provides a floating type high-temperature non-metal roller way for a microlite heating furnace. High-temperature non-metal roller shafts are supported through the cooperation of supporting mechanisms on the two sides of a frame body, and the high-temperature non-metal roller shafts are driven to rotate through elastic transmission shifting pieces. Floating supporting plates and fixed supporting plates in the supporting mechanisms are elastically connected, when a certain roller shaft is large in surface runout deviation and concentrated in stress, the floating supporting plates can compress springs, and the floating supporting plates can move up and down in a reciprocating mode relative to the fixed supporting plates in cooperation with the guiding effect of guiding grooves on supporting shafts; and the high-temperature non-metal roller shafts can float up and down relative to a rack, the force borne by the roller shafts can be distributed to the other roller shafts along with downward movement
