Problems solved by technology

[0003] The disadvantages of the above-mentioned prior art are: the die head is heated by means of setting a heating plate on the side of the die head, resulting in a slow heat conduction rate (after starting up, the working temperature can only be reached after heating for more than 4 hours, and the mold can only be turned off after 4 hours of equilibrium. Head heat penetration) and low heat conduction efficiency, so the energy consumption is high, which is not conducive to energy saving

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 a spinning box body of a spunbonded nonwoven fabric equipment, in particular to an energy-saving spinning die for the spinning box. Background technique [0002] Chinese patent ZL200520047626.4 discloses a spinning box of a spunbonded non-woven fabric equipment, which includes a melt inlet, several stages of conveying pipelines, each stage of conveying pipelines is provided with several pipeline outlets, and each stage of conveying pipeline outlets are in turn Set up the next-level conveying pipeline. Below the pipe outlet of the bottom-most conveying pipeline is a filter screen. Below the filter screen is a porous distribution plate with equally sized holes. The melt finally flows out evenly from the holes of the porous distribution plate and enters Spinneret. The melt flows through the outlets of the pipes arranged in several stages to pass through the porous distribution plate with holes of different sizes...
