Embodiment Construction
[0025] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0026] Such as figure 1 , figure 2 As shown, the pitch carbon fiber precursor spinning device includes a main frame 3, an extrusion assembly 1 for stirring the melt is installed on the main frame 3, and a spinning assembly 2 and a metering pump are arranged at the output end of the extrusion assembly 1 61. The metering pump 61 is driven and controlled by the metering pump power source 6. It also includes a winding head assembly 4 and an electric control cabinet 5 for winding the wire into a coil, and the winding head assembly 4 and the electric cabinet 5 are installed at the bottom of the main frame 3 .
[0027] Such as image 3 As shown, the specific structure of the extrusion assembly 1 is as follows: including the first sub-frame 101 and the fan temperature control port 113, the reducer 102 is installed on the first sub-frame 101, a...

The invention relates to a pitch carbon fiber precursor spinning device which comprises a main rack, wherein the main rack is provided with an extrusion component for stirring a fusant, wherein the output end of the extrusion component is provided with a spinning component and a metering pump; the pitch carbon fiber precursor spinning device also comprises a winding head component for winding filaments into filament rolls and an electric control cabinet. The pitch carbon fiber precursor spinning device is simple in structure and convenient to use; by use of an internal-gearing counter-rotating twin-screw, the uniformity of fusant flow can be effectively ensured; by use of a blower temperature control opening and a heating block, control over the internal temperature of the fusant can be effectively realized, and the uniformity of the fusant temperature is ensured; by use of a power source and a turntable, clamping head position conversion is easily realized; by virtue of an arranged locking component, locking and rotation of the turntable are relatively flexible; by virtue of an arranged speed-measuring godet wheel, the filament length can be fed back to the power source in real time, so that the purpose of controlling the output rotation speed of the power source is achieved. The pitch carbon fiber precursor spinning device has the advantages of flexibility in switching and high automation degree; by virtue of the pitch carbon fiber precursor spinning device, the production efficiency is greatly improved.
Description
technical field [0001] The invention relates to spinning equipment, in particular to a pitch carbon fiber precursor spinning device. Background technique [0002] The spinning device is a machine that makes the fiber-forming polymer solution or melt into filaments. At present, the melt extrusion device of the existing spinning equipment adopts a single-screw structure, which has high quality, stable operation, and load-bearing capacity. It has the advantages of large force, but the single-screw structure cannot take into account the uniformity of the flow rate of the asphalt melt, and the asphalt melt is easy to entrain gas and impurities, and the temperature of the melt cannot be guaranteed at the same time. In addition, the chuck of the existing spinning device cannot Realize pitch carbon fiber winding. Contents of the invention [0003] In view of the above-mentioned existing problems, the applicant has carried out research and improvement, and provides a pitch car...
