Spinning box

Abstract

The invention relates to mechanical manufacturing of chemical fiber filament, in particular to a spinning box. According to the invention, the spinning box is achieved by the following technical scheme: the spinning box comprises a frame, a yarn spraying tank, an air blowing mechanism, a yarn guide module, a yarn leading module and a yarn collecting box, wherein the yarn spraying tank is arranged at the upper part of the frame; the air blowing mechanism is used for blowing air to yarns; the yarn guide module is arranged between the two sides of the frame; the yarn leading module is arranged between the two sides of the frame and positioned below the yarn guide module; the yarn collecting box is arranged below the frame; the yarn spraying tank comprises a tank cylinder and a yarn spraying plate, a yarn cup and a fluid passing body, wherein the yarn spraying plates are mounted in the tank cylinder and are provided with at least two yarn spraying areas with a plurality of fine holes; the yarn cup is provided with fluid passages corresponding to the yarn spraying areas one to one; the fluid passing body is provided with a fluid inlet and provided with shunting passages, which are communicated with the fluid inlet and corresponding to the fluid passages one to one; and the bottom of each fluid passage is a filter plate with a plurality of micro holes. According to the invention, the yarn spraying tank has no flowing dead point so that broken filaments and broken ends are prevented; moreover, as high yarn yield is obtained, the spinning box provided by the invention is beneficial for increasing production efficiency.

[0002] The spinning box in the prior art is generally a kind of spinning box disclosed in the invention patent application with the publication number CN1176320A; A spinning assembly capable of eliminating dead spots in melt flow disclosed in a patent application for invention includes an upper flow cover, an assembly cover, an assembly body, a sand cup and a spinneret, the sand cup is an annular sand cup, and the The inner cavity of the annular sand cup can be an annular inner cavity. The center of the annular sand cup is solid, and the annular cavity is filled with filter sand. However, the above-mentioned structure has restrictions on the distribution of the spinneret holes, just as the above-mentioned invention patent The spinneret described in the application only has plate holes in its outer ring and has only one ring, resulting in low efficiency of yarn production by this spinning assembly and low yarn yield
