Row-type gathering blowing duct for the drafting area of ​​the traveling cleaning system of the roving frame

Abstract

The invention provides a row type converging air blowing duct used for a roving frame travelling cleaning system drafting zone. The row type converging air blowing duct comprises an air blowing duct body composed of an L-shaped rigid section on the upper portion, a vertical expansible section in the middle and a vertical rigid section on the lower portion, a flat quadrate air blowing nozzle I which blows air horizontally directly facing a table top of a roving frame, three to six branching air blowing nozzles II are arranged in the middle, and the lengths of the branching air blowing nozzles II are decreased progressively in sequence from bottom to top, the branching air blowing nozzles II uniformly blows air at equal intervals along drafting cotton threads of the roving frame drafting zone so as to reduce the loss of the air-out amount, the air-out flow directions of the branching air blowing nozzles II are finally converged to one point of the table top, and the converged point intersects and converges with the horizontal air blowing flow direction of the flat quadrate air blowing nozzle I, so that flyings in the roving frame drafting zone are efficiently converged to a suction port of an air-suction duct and then taken away. The row type converging air blowing duct is low in air volume loss, the efficient utilization rate of the air volume of branching air blowing ducts is higher, and the treatment effect on the flyings in the roving frame drafting zone is more ideal.

Description

technical field [0001] The invention belongs to the technical field of blowing and sucking air ducts of a roving frame cleaning system, and in particular relates to a row-type gathering blowing duct used in a drafting area of ​​a roving frame itinerant cleaning system. Background technique [0002] When the roving frame is in operation, a large amount of flying flowers, dust and linters will be suspended in the workshop, which will adversely affect the production environment of the workshop and the cleanliness of the fabric. The blowing and suction ducts of the roving frame cleaning system adopt positive rotary velvet belt top and bottom roller cleaning devices, and are equipped with roving cleaners and blowing and suction ducts, and cooperate with the main exhaust fan of the rear table suction system through the table blowing system Linked to form a circuit suction system. Taking the invention whose authorized announcement number is 203653835U as an example, although it pr...
