Segmental-color roving frame

Abstract

The invention designs a segmental-color roving frame. The segmental-color roving frame comprises a feeding device, a stretching device, a twisting mechanism and a coiling forming device which are installed on a frame orderly from back to front. The creative point of the segmental-color roving frame is that the feeding mechanism is composed of a guide strip roller cylinder, a guide strip roller and a horn; the stretching mechanism is composed of a rock frame fixing strut, four groups of rollers, a special section tube and a lattice apron; the twisting framework is composed of an ingot, an ingot wing and a false twister; the coiling forming mechanism is composed of a drive mechanism, a bobbin and a keel. The segmental-color roving frame effectively combines high and lower guide strip rollers with independently controlled motor, breaks through the roving technology that the traditional roving frame only can produce the fiber variety between every two sections or colors are basically consistent to each other; two fiber strips can feed and stretch at the same time, and spin the roving yarn consisting of different colors or different fibers between sections.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a design of a roving frame. Background technique [0002] In the prior art, the tasks of the roving process in the spinning process mainly include: 1. Drafting: the sliver is drawn and thinned to become a roving; 2. Twisting: adding a certain twist to the roving to improve the strength of the roving; Avoid accidental elongation during winding and unwinding, and prepare for spun yarn drafting; 3. Winding: Wind the twisted roving on the bobbin to make a package of a certain shape and size, so that Storage, handling and adaptation of the feed on spinning frames. [0003] However, the roving frame in the prior art can only draft one fiber sliver to spin a roving with uniform thickness, and the fiber types or colors between the sections of the roving are basically the same, so it is impossible to draft two fiber slivers. There are rovings of different colors or differen...
