Problems solved by technology

[0003] The weak point of above-mentioned prior art is: die head adopts the mode heating that heating plate is arranged on die head side, causes heat conduction speed relatively slow (after starting up, just can reach operating temperature after heating more than 4 hours, and just can mold after 4 hours of equilibration. Head heat penetration) and low heat conduction efficiency, so the energy consumption is high, which is not conducive to energy saving

Embodiment 1

[0027] See Figure 1-4 , the energy-saving spinning die head for the spinning box of the present embodiment comprises: a pair of die head bodies 1 with symmetrical structures, and a plurality of sections of square wave heat transfer oil passages 11 are distributed in the inner wall of the die head body 1; , The liquid outlet holes 1-3, 1-4 are respectively connected with the heat transfer oil inlet pipe 12 and the heat transfer oil outlet pipe 13.

[0028] The liquid inlet 1 - 3 is adjacent to the bottom of the die head body 1 , and the liquid outlet 1 - 4 of the heat transfer oil channel 11 is adjacent to the top of the die head body 1 .

[0029] The heat transfer oil passage 11 includes: a pair of transverse passages 1-1 distributed up and down, a plurality of longitudinal passages 1-2 connected between the pair of transverse passages 1-1; the process holes 1 of the longitudinal passages 1-2 -5 is on the top surface of the die body 1 and is sealed in use, and the process ho...

Embodiment 2

[0031] See Figure 5-9 , on the basis of Embodiment 1, the spinning die head for the spinning box of this embodiment has the following modification, that is: only a melt inlet 2 is provided at the central upper end of the inner wall of one die head body 1, and a melt inlet 2 is provided on each die head On the inner wall of the head body 1 and symmetrically distributed on both sides of the melt inlet 2, there are multi-stage conveying grooves 4 suitable for communicating with the melt inlet 2 during use, and the openings at both ends of the conveying grooves at each stage face The lower outlet is connected to the central part of the conveying trough of the next stage; the outlets of the conveying trough of the last stage are evenly distributed.

[0032] 200 mesh or 250 mesh filter screens 6 are arranged at the lower ends of the outlets at both ends of the final conveying tank in turn, and distribution plates 3 and spinneret plates 7 with through holes are evenly distributed. ...

Abstract

The invention relates to an energy-saving type spinning die head for a spinning box. The spinning die head comprises a pair of die head bodies with symmetrical structures, wherein multiple segments of square wave heat-conducting oil channels are distributed on the inner walls of the die head bodies; and the liquid inflow holes and liquid outflow holes of the square wave heat conducting oil channels are respectively connected with a heat conducting oil inflow pipe and a heat conducting oil outflow pipe. The spinning die head for the spinning box provided by the invention has the advantages that multiple segments of square wave heat-conducting oil channels are arranged on the inner walls of the die head bodies, so that the die head bodies are directly heated by heat conducting oil, thus the die head has the characteristics of higher heat conduction speed, high heat conduction efficiency and energy conservation; and shorter square wave heat conducting oil channels are suitable for ensuring that the flow rates at the heat conducting oil inflow holes and outflow holes are basically consistent, thus the integral temperature uniformity of the die head is ensured and the production quality of a product is improved.

Description

technical field [0001] The invention relates to the technical field of spinning boxes of spunbonded nonwoven equipment, in particular to an energy-saving spinning die head for spinning boxes. Background technique [0002] Chinese patent ZL200520047626.4 discloses a spinning box of spunbonded nonwoven equipment, which includes a melt inlet, several stages of conveying pipelines, each stage of conveying pipelines is provided with several pipeline outlets, and the outlets of each stage of conveying pipelines are in turn Set up the next level of conveying pipeline, the outlet of the lowest level conveying pipeline is under the filter screen, and under the filter screen is a porous distribution plate with holes of equal size. The melt finally flows out evenly from the holes of the porous distribution plate and enter spinneret. The melt flows through the outlet of the pipeline set in several stages and passes through the porous distribution plate with holes of different sizes, so...
