The invention relates to the technical field of polyester yarn processing, and discloses a thermal stretching equipment for polyester yarn processing, which includes a preheating box and a thermal stretching box. A flow equalizing tube is fixedly installed inside the preheating box, and the flow equalizing tube is hollow. The cylinder has air inlet holes on the surface of the flow equalizing pipe, and several air inlet holes are distributed along the half side of the flow equalizing pipe in an arc from the bottom of one end to the top of the other end. There is one group of air holes, two groups are arranged on the surface of the flow equalizing pipe, and the two groups of air inlet holes are symmetrically distributed about the central axis of the flow equalizing pipe. In the present invention, air inlet holes are provided on the flow equalizing pipe and multiple groups of air inlet holes are distributed in arcs from the bottom of one end of the flow equalizing pipe to the top of the other end, so that the air inlet holes on the same group of arcs complete the spinning half Direct blowing and heating on the side, two sets of symmetrical air inlets complete the complete circumferential side heating of the spinning, when the spinning passes through the uniform flow tube at a uniform speed, the air volume and time of each point on the surface are synchronized, preheating The effect is more even.
Description
technical field [0001] The invention relates to the technical field of polyester yarn processing, in particular to a thermal stretching device for polyester yarn processing. Background technique [0002] During the processing of polyester yarn, it is necessary to stretch the polyester spinning. Before stretching, the spinning needs to be heated and softened. Because the spinning is stretched under the condition of uneven heating, wool, broken ends, Therefore, it is necessary to preheat the spinning before heating. Currently, there are two methods of water bath preheating and hot air preheating. Among them, the water bath is preheated, the resistance of the water body to the surface of the spinning bundle will cause damage to it, and the preset spinning needs to be dried before passing through the oiling roller, the process is cumbersome, and it is difficult to achieve effective protection for the spinning Control, gradually replaced by hot air preheating, and in order to ac...
