Fiber reinforced thermoplastic composite material pair-roller mixing equipment relates to fiber reinforced thermoplastic composite material processing production equipment. A front left panel, a left side panel and a rear left panel of the mixing equipment are fixed on a bottom plate, mixing rollers are longitudinally arranged on the front left panel and the left side panel and a front right panel and a rear right panel; a left middle plate and a right middle plate which are vertically placed are arranged between the left and right mixing rollers. The mixing roller outer wall is a corrugated circular arc structure, and reduces the shear abrasion to enhanced fiber; an intermediate plate can play the role of a scraper; after feeding of the mixing equipment is stopped, a mixed material in the mixing equipment still can flow out, no accumulation of waste material is produced, the waste of raw materials can be reduced; the mixed material can be directly sent to a press for mould pressing production, fiber silk, fiber cloth, fibrofelt and other reinforced materials in various forms can be used, diversified product demands can be met, one machine has multi functions, and the equipment has the advantages of simple structure, convenient maintenance, and effective reduction of the production cost and maintenance cost.
