Description

Technical Field

[0001] The invention relates to the technical field of flat wire production and related equipment, and in particular to a plastic extrusion flat film wire drawing machine unit and a wire drawing process. Background Art

[0002] Flat yarn, also known as cut fiber, is the basic material for producing plastic woven fabrics. Flat yarn is made of a specific variety of polypropylene and polyethylene resins, which are melt-extruded into films, and then cut into strips longitudinally. The strips are heated, stretched and oriented at the same time, and finally wound into flat yarn spindles for weaving woven fabrics. The flat yarn process includes: raw material modification, blending, coloring, filling, formulation, etc.

[0003] Flat wire process, also known as yarn making process, is the first and most important process in the production of plastic woven fabrics. Flat wire production process methods are divided into two types according to the film forming method, tube film and flat film. According to the cooling method after film forming, there are air cooling, water cooling and indirect cooling. According to the drafting heating method, there are hot plates, hot rollers, and hot air. According to the spindle winding forming, there are centralized cycloid winding, single spindle torque motor winding system, and magnetic torque winding. For example, the existing public document CN214491515U-A flat wire extrusion flat film rolling production line equipment for warp knitting machines discloses a device that can be used for flat wire production;

[0004] Although the existing disclosed plastic extrusion flat film drawing unit can realize plastic drawing, it still has certain shortcomings in actual use: first, when the existing plastic is melted and extruded in the extruder conveying barrel, it is mainly heated through the annular heating plate spaced apart on the outer wall of the conveying barrel through the outer wall of the conveying barrel. Since the amount of plastic at the bottom of the conveying barrel during the screw conveying process is greater than the amount at the other three positions above, the amount of plastic accumulated at the bottom is large, and heat is difficult to transfer quickly. Under the action of the annular heating plate, uniform heating cannot be achieved. At the same time, since the amount of plastic at the four positions is different, but the heating amount is the same, Heat loss is prone to occur, increasing energy consumption; secondly, after the existing plastic flat film is extruded and cooled, the plastic flat film is cut into flat wires of a certain width by a slitting device, and the distances between the multiple cutters used for slitting are fixed, and cannot be adjusted accordingly according to the width requirements of the flat wires, affecting the scope of application; finally, after the existing plastic flat film is extruded, its tension is directly adjusted by a tensioning roller, and the tension adjustment is relatively simple, and when the tension range to be adjusted is wide, it takes a long time, affecting work efficiency; therefore, it is necessary to improve the existing technology to solve the above technical problems. Summary of the invention

[0041] Specifically, it includes an extrusion barrel 100, a feeding tank 101 is arranged on one side of the top of the extrusion barrel 100, an extrusion blade 102 is arranged inside the extrusion barrel 100, and one end of the extrusion blade 102 is connected to a driving mechanism 103; a flat film device 200 is arranged on one side of the extrusion barrel 100; a cooling device 300 is arranged on the other side of the flat film device 200; a guide roller frame 400 is installed on the other side of the cooling device 300; and,

[0042] For details, please refer to Figure 2 , Figure 4 , Figure 5 and Figure 6The heat regulating assembly 500 comprises a heat-insulating sleeve 501 sleeved on the outer wall of the extrusion barrel 100 and heating plates 503 evenly spaced along the circumferential direction of the heat-insulating sleeve 501, partitions 501a are evenly spaced on the inner wall of the heat-insulating sleeve 501, and chutes 501b are evenly spaced along the circumferential direction on both sides of the inner wall of the heat-insulating sleeve 501, and electromagnetic blocks 502 are embedded on both sides of the inner wall of the chutes 501b, and the heating plates 503 are located between adjacent partitions 501a, and the heating plates 503 The surface of the heating plate 503 is provided with sliding holes 503a in an array in the horizontal direction, and the inside of the sliding holes 503a is slidably connected with graphene heat-conducting columns 505, and sliders 504 are installed in the middle of the outer walls of both sides of the heating plate 503; wherein, the outer wall of the graphene heat-conducting column 505 is in contact with the inner wall of the adjacent sliding hole 503a, the slider 504 is slidably connected to the inside of the adjacent slide groove 501b, and the outer wall of the slider 504 is wrapped with an iron sheet, and the other end of the graphene heat-conducting column 505 passes through the outer wall of the extrusion barrel 100.

[0043] When the above arrangement is used, in the plastic extrusion wire drawing process, plastic particles and additives are first fed into the extrusion barrel 100 through the feeding tank 101, and then the extrusion blades 102 are driven to rotate continuously under the action of the driving mechanism 103, so that the molten plastic can be extruded.

[0049] When the above arrangement is used, after the plastic is melted and extruded, a flat film is formed and extruded under the action of the flat film device 200, and then the extruded flat film is cooled by the cooling device 300, and then it can be rolled up on the winding device under the action of the guide roller, the guide rod 401, the film pressing roller 402, etc., wherein, when the flat film is located between the guide rod 401 and the film pressing roller 402 after cooling, the flat film is cut and formed into a plurality of flat wires under the action of the multiple sets of cutters 606a (the cutters 606a are only collected and rotated clockwise under the rotation of the fixing ring 606 and the round rod 601b) , the cutter 606a cannot continue to rotate counterclockwise when it is in the vertical cutting direction). In order to adjust the width of the flat wire according to different needs, at this time, the magnetic ring 607a in the corresponding fixed shell 607 above the cutter 606a is energized at uniform intervals according to the needs.

Through the connection of the rotating shaft 703a, the rotation of the second toothed disc 702 will drive the corresponding rotating plate 703 to rotate, and under the action of the rotating plate 703, the two adjusting rollers 704 on its surface can be driven to rotate, so as to achieve the purpose of adjusting the stretching and squeezing of the flat wire, thereby adjusting the tension of the flat wire, and at the same time, the purpose of adjusting the tension twice can be achieved in a single moving distance, and the adjustment effect is good.

[0054] Furthermore, since the racks on the outer walls on both sides of the lifting frame 701a are meshed with the racks on the outer walls of the adjacent second toothed discs 702, the second toothed discs 702 on both sides will be driven to rotate when the lifting frame 701a rises or falls, wherein the second toothed discs 702 and the corresponding rotating plates 703 can be connected through the rotating shaft 703a to play a transmission role.
