The invention relates to a sheath injection type water-blocking factice filling equipment and production technology, and belongs to the technical field of communication optical cable product production. The sheath injection type water-blocking factice filling equipment comprises an electrical control cabinet, a factice barrel, an injection device and an operation controller, wherein one side of the electrical control cabinet is connected with the factice barrel through a factice conveyer pipe a, the other side of the electrical control cabinet is connected with the injection device through a factice conveyer pipe b, and the operation controller is installed on one side of the injection device. After factice in the factice barrel is conveyed to an oil gun and an injection oil needle, the injection oil needle swings above a steel aluminum band and injects the factice on the steel aluminum band in an S shape, and the factice after entering into a lateral wrapping die wraps an optical cable core with the steel aluminum band in a circular shape. The water-blocking factice filling amount is great for current whole-process filling, and the manufacture cost is high. The factice spraying pollutes environment and may damage electric components, which may cause unqualified products such as breaking strands or cables. The manufacture cost is further increased.
