It should be understood that the following description is only used to describe one or several specific embodiments of the present application and does not strictly limit the scope of the protection claimed by the present application.

[0055] Referring to Figures 1-3 A gel spinning device, and its technical points are:

[0056] Comprise:

[0057] A jacketed constant temperature solvent tank 1 for storing and heating solvent; a resin storage tank 2 for storing resin;

[0058] A spiral pipe mixer 3 for preliminary mixing of resin and solvent;

[0059] A micro-channel mixer 4 connected to the output end of the spiral pipe mixer 3 for further uniform mixing of the solution;

[0060] A screw extruder 5 connected to the output end of the micro-channel mixer 4 for heating, shearing and generating spinning melt of the mixed solution;

[0063] A godet 9 for guiding the cooled gel spinning into a gel spinning can 91 located at one side of the godet 9.

[0064] Referring to Figure 1The jacketed constant-temperature solvent tank 1 and the resin storage tank 2 are raw material storage devices of the gelatinous filament production device, wherein the jacketed constant-temperature solvent tank 1 is used for storing and heating the solvent to ensure the fluidity of the solvent at a constant temperature so as to be fully mixed with the resin. The resin storage tank 2 is used for storing the resin raw material to maintain the stability of the resin. During the operation, the raw materials in the jacketed constant-temperature solvent tank 1 and the resin storage tank 2 are accurately added to the spiral pipeline mixer 3 in proportion through the liquid metering scale 11 and the loss-in-weight feeder 21, so as to ensure the accurate proportion of the raw materials and avoid the unstable quality of the gelatinous filament due to inaccurate proportion.

[0065] Referring to Figure 1 The liquid metering scale 11 is used for accurately metering the flow of the solvent, which ensures the constant and accurate flow of the solvent in the jacketed constant-temperature solvent tank 1. The metering device can adjust the addition amount of the solvent in real time according to the set production requirements, so as to ensure that the mixing ratio of the resin meets the production requirements and avoid the uneven mixing or incorrect proportion.

[0066] Referring to Figure 1 The loss-in-weight feeder 21 is arranged between the resin storage tank 2 and the spiral pipeline mixer 3, which can accurately provide the resin in a set amount and has a high-precision control system to prevent any fluctuation or inaccuracy during the addition of the raw materials. The accurate feeding capacity of the loss-in-weight feeder 21 ensures the continuous supply of the resin and ensures that the resin and the solvent reach the ideal ratio during the mixing process, thereby affecting the performance and quality of the gelatinous filament.

[0067] Referring to Figures 1-2 The spiral pipeline mixer 3 comprises a mixer shell 31, one end of the mixer shell 31 is provided with a motor 32, the output end of the motor 32 is connected with a spiral rod 33, and the spiral rod 33 is provided with a propeller 34; the bottom of one end of the mixer shell 31 is provided with a first heat-conducting oil inlet 313, and the upper portion of the other end is provided with a first heat-conducting oil outlet 314; the top of the mixer shell 31 is provided with a first mixed liquid inlet 311, and the bottom of the mixer shell 31 is provided with a first mixed liquid outlet 312.

The micro-channel pipe 42 of the micro-channel mixer 4 realizes the secondary mixing of the mixed liquid through multiple separation and aggregation, so that a more uniform mixing effect is achieved. The design of the second heat conducting oil inlet 411 and the second heat conducting oil outlet 412 ensures that the micro-channel mixer 4 can stably control the temperature during the working process, avoids the negative influence of temperature fluctuation on the mixed liquid, and ensures the mixing effect and the quality of the gel fiber.

[0070] Referring to Figure 1 The output end of the screw extruder 5 and the spinning beam 7 are provided with a melt filter 51; the melt filter 51 is used for removing impurities in the mixed liquid, ensuring that the melt entering the spinning beam 7 is pure, and will not have any influence on the subsequent spinning process. The fine filtering function of the melt filter 51 can effectively prevent impurities from entering the spinning process, and ensure the high quality of the gel fiber.

[0071] The top of the spinning beam 7 is provided with a metering pump 6; the metering pump 6 ensures that the melt in the spinning process can enter the spinning beam 7 according to the accurate flow, and maintains the uniform and stable production state. The metering pump 6 cooperates with the melt filter 51 to control the flow of the melt, avoids too much or too little melt from entering the spinning beam 7, and thus affects the production quality of the gel fiber.

[0073] When in use, the raw materials are added into the jacketed constant-temperature solvent tank 1 and the resin storage tank 2, and the raw materials in the jacketed constant-temperature solvent tank 1 and the resin storage tank 2 are added into the spiral pipeline mixer 3 according to a specific proportion through the liquid metering scale 11 and the loss-in-weight feeder 21;
