Description

Technical Field

[0001] The invention relates to the field of fiber filament processing equipment, in particular to a chemical fiber drawing device for textile production. Background Art

[0002] Textile fiber refers to the fiber used to weave cloth, which is the basic raw material of the textile industry. At present, textile fibers include natural fibers, chemical fibers, etc. Chemical fibers are fibers synthesized or processed by chemical methods. For example, polyester fiber (polyester), which is a polymer compound made by polycondensation of organic dibasic acids and diols, has the characteristics of high strength, good elasticity, strong wrinkle resistance, etc., and is widely used in clothing, home textiles and other fields.

[0003] In order to process raw materials into fibers, it needs to go through multiple steps such as raw material preparation, spinning fluid preparation, spinning molding, and post-processing. Raw material preparation Natural raw materials need to be chemically treated to form a viscous spinning solution, while synthetic raw materials need to be chemically synthesized into high molecular polymers. Preparation of spinning fluid The fiber-forming polymer is prepared into a spinning fluid by melting or solution method. Spinning molding squeezes the spinning fluid out of the spinneret's spinneret hole to form a thin stream, and then solidifies it into filaments in an appropriate medium, which is also called textile drawing. Post-processing is a series of post-processing treatments, such as stretching, heat setting, oiling, cutting, etc., to improve the physical properties of the fiber.

[0004] Each of the above steps needs to be equipped with corresponding equipment, such as a spinning machine corresponding to the spinning forming step. At present, there are many types of spinning machines, such as a spinning device disclosed in a Chinese patent with publication number CN1132972C, which includes a spinneret with spinneret holes for extruding filaments; a blowing device that can cool the extruded filaments immediately after leaving the spinneret holes; a container filled with spinning bath; a steering element, which is placed in the spinning bath to bundle and deflect the spun filaments; and an air gap defined as the distance between the spinneret and the spinning bath surface; characterized in that the steering element is designed so that it does not rotate itself when the filaments are deflected.

[0005] The spinning device provided by the above-mentioned patent, or other types of spinning devices, all include a spinneret and a cooling device. Therefore, when the raw material is output and formed into a filament through the spinneret, it can be cooled by a cooling component to accelerate its solidification. Although the spinning device provided by the above-mentioned patent, and the cooling components of other types of spinning devices can realize the cooling treatment of the fiber filaments, they all realize the cooling treatment of the fiber filaments by controlling the flow of gas and moving the vertical filaments, and this method has defects. For example, when the gas flows in the same direction, it cannot fully contact the fiber filaments, resulting in uneven cooling of the fiber filaments at various positions, and even the fiber filaments at the edge are not cooled as much as the fiber filaments in the middle. For example, the gas is mostly room temperature gas, and even in a high-temperature workshop, the temperature of the gas is high, resulting in a small temperature difference between it and the fiber filaments, which is not conducive to realizing the cooling treatment of the fiber filaments.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0037] Example 1

[0038] like Figure 1 , Figure 2 , Figure 4 , Figure 7As shown, in order to improve the cooling effect of the fiber filaments, this embodiment provides a new spinning and drawing device, which includes a silo 1, a spinneret 4, a cooling assembly 2, an air cooling assembly 5, etc. The silo 1 can store molten raw materials, that is, spinning fluids. The spinneret 4 is detachably arranged at the discharge port 12 at the bottom of the silo 1. The cooling assembly 2 is arranged directly below the spinneret 4, and the inner side is arranged as a cavity structure. At the same time, the upper and lower side walls are provided with perforations 21 for the fiber filaments to pass through. Therefore, the fiber filaments output from the spinneret 4 enter and exit the cooling assembly 2 through the perforations 21, which facilitates the cooling treatment of the fiber filaments through the cooling assembly 2. In order to enable the fiber filaments to be cooled and cooled during the movement of the cooling assembly 2, the air cooling assembly 5 is arranged on the side of the cooling assembly 2. When it is working, it can pump external gas into the cooling assembly 2, and in the process of pumping gas, it can cool the gas, reduce the gas temperature, and then make the low-temperature gas flow into the cooling assembly 2. Under the action of the air cooling component 5, the low-temperature gas entering the cooling component 2 is discharged from the perforations 21 and is in full contact with the fiber filaments during discharge, thereby improving the cooling effect of the fiber filaments.

[0039] like Figure 8 As shown, in order to make the material output from the silo 1 into filaments, the spinneret device 4 includes a spinneret disk 45, on which a plurality of spinneret holes 46 are provided, and the spinneret disk 45 is installed at the discharge port 12 of the silo 1. Therefore, the material stored in the silo 1 passes through the spinneret holes 46 and is output in filaments, thereby realizing the spinning process of fiber processing.

[0040] like Figure 4 , Figure 8 As shown, in order to enable the spinneret 45 to be stably installed on the silo 1 and to be disassembled and replaced as needed, the spinneret device 4 also includes a connecting ring plate 41. The cross-section of the connecting ring plate 41 is set to an L-shaped structure, and an internal thread structure 42 is provided on the inner wall. At the same time, an external thread structure 13 is provided at the bottom of the outer wall of the discharge port 12. Therefore, with the cooperation of the internal thread structure 42 and the external thread structure 13, the connecting ring plate 41 can be stably installed at the discharge port 12 of the silo 1, and at the same time, the spinneret 45 can be stably supported, so that the spinneret 45 can be stably installed in the discharge port 12.

[0041] like Figure 8 As shown, in order to enable the spinneret 45 and the connecting ring plate 41 to be stably connected, a convex plate 44 is fixedly provided at the bottom of the side wall of the spinneret 45, and a groove 43 is provided on the inner side of the connecting ring plate 41, and the convex plate 44 is located in the groove 43, thereby realizing the stable connection between the connecting ring plate 41 and the spinneret 45.

[0042] like Fig. 9As shown, in order to allow the output fiber filaments to pass through the cooling assembly 2, the cooling assembly 2 includes a bin body 23 and an upper plate body 22. The bin body 23 is configured as a cylindrical structure with an opening upward, and the upper plate body 22 is detachably arranged at the opening of the bin body 23 by bolts. A plurality of through holes 21 are arranged on the bottom plates of the upper plate body 22 and the bin body 23. The through holes 21 are aligned with the spinneret holes 46 one by one, and the diameter is larger than the diameter of the spinneret holes 46. Therefore, the fiber filaments output from the spinneret device 4 can enter and exit the cooling assembly 2 through the through holes 21. Since the cooling assembly 2 is configured as a cavity structure, the low-temperature gas stored in the cooling assembly 2 can realize the cooling and curing treatment of the fiber filaments and fully contact the fiber filaments.

[0043] like Fig. 9 As shown, multiple tubes 25 may be arranged inside the bin body 23, the bottom of the tube 25 is connected to the through hole 21 of the bin body 23, and the top is inserted into the through hole 21 of the upper plate body 22, and multiple dispersion holes are arranged on the side wall of the tube 25. When the fiber filaments penetrate the tube 25, the low-temperature gas stored in the cooling assembly 2 flows into the tube 25 through the dispersion holes and is output from the through hole 21.

[0044] like Fig. 9 , Fig.10 As shown, in order to output gas into the cooling assembly 2, an air pipe 24 of an annular structure is provided on the outer side of the bin body 23, and the output end of the air pipe 24 is connected to the bin body 23. The air cooling assembly 5 includes an air pump 51, the air outlet end of the air pump 51 is connected to the air pipe 24, and a support plate 52 is provided above, and the top of the support plate 52 is connected to the connecting ring plate 41. Therefore, the air pump 51 is stably installed on the side of the cooling assembly 2, and can stably pump external gas into the cooling assembly 2, thereby realizing the rapid cooling and solidification of the fiber filaments in the air cooling mode.

[0045] like Fig.10 , Fig.11As shown in the figure, in order to reduce the temperature of the gas entering the cooling component 2, the air-cooling component 5 further includes an intake cylinder 53 and a semiconductor refrigeration sheet 54. The intake cylinder 53 is communicatively arranged at the intake end of the air pump 51, and the end far from the air pump 51 is set as an opening, and at the same time, through holes are provided on the lower side wall. A partition 55 is arranged inside the intake cylinder 53. The partition 55 is set as a U-shaped structure, and its height is equal to the height of the inner space of the intake cylinder 53. At the same time, its length and width are both smaller than the length and width of the inner space of the intake cylinder 53. The partition 55 is installed in the intake cylinder 53 by being connected with bolts, and the opening end is flush with the opening of the intake cylinder 53. Therefore, an air passage 57 is formed between the partition 55 and the intake cylinder 53. That is, under the action of the air pump 51, the outside gas enters the intake cylinder 53 from this air passage 57 and then flows into the air pump 51. In order to reduce the temperature of the gas entering the air passage 57, two semiconductor refrigeration sheets 54 are respectively installed on the two opposite side walls of the partition 55, and the cold ends are in contact with the gas, so that the heat of the gas can be absorbed when the semiconductor refrigeration sheet 54 is powered on and working, reducing the temperature of the gas. In order to timely discharge the heat generated by the semiconductor refrigeration sheet, a fan 56 is arranged below the through hole of the intake cylinder 53. When the fan 56 works, it can extract the heat accumulated in the partition 55 from the intake cylinder 53 and discharge it outside, and at the same time stir the gas to flow on the side of the semiconductor refrigeration sheet 54 to realize its dimensional heat dissipation treatment.

[0046] As Figure 7 , Fig.12 shown in the figure, in order to stably install the cooling component 2 below the spinning device 4, multiple sets of connecting plate groups 6 are arranged between the connecting ring plate 41 and the upper plate body 22. The multiple sets of connecting plate groups 6 are evenly distributed along the circumferential direction of the connecting ring plate 41, and the upper and lower ends are respectively connected to the connecting ring plate 41 and the upper plate body 22, and are in an adjustable state at the same time. Therefore, under the action of the connecting plate group 6, the upper plate body 22 is stably installed below the connecting ring plate 41.

[0047] As Fig.12 shown in the figure, specifically, the connecting plate group 6 includes a top plate 61 and a bottom plate 63. The top plate 61 is set as a U-shaped structure, and the opening faces downward. At the same time, convex columns 62 are fixedly arranged on the inner side wall. The top of the bottom plate 63 is inserted into the top plate 61, and a pressing bolt 65 that threadedly penetrates the end of the top plate 61 presses the bottom plate 63. At the same time, the convex column 62 is located in the arc-shaped groove 64 of the bottom plate 63, realizing the stable and detachable connection between the bottom plate 63 and the top plate 61. Under the condition of meeting the stable installation of the cooling component 2, it provides support for adjusting the height of the cooling component 2 according to needs. The support plate 52 can also be set to be adjustable with reference to the connecting plate group 6 to adapt to the installation of the cooling component 2.

[0048] As Figure 2 , Figure 4 , Figure 5 , Fig.13As shown, in order to stably install the silo 1 in the workplace, a frame 11 is provided on the outside of the silo 1, and the top of the frame 11 is supported on a bracket 7. The bracket 7 is stably installed in the workplace, thereby stably supporting the silo 1 to output the fiber yarn and providing convenience for the next step of processing of the fiber yarn.

[0049] like Figure 5 As shown, specifically, an ear plate is provided at the top of the frame 11, and a limiting rod 14 is fixedly provided at the end of the ear plate, and a fastening bolt 15 is provided through it, and a clamping plate 16 is provided below the end of the ear plate. A limiting hole 17 and a threaded hole 18 are provided on the clamping plate 16, the limiting rod 14 is provided through the limiting hole 17, and the bottom thread of the fastening bolt 15 is provided through the threaded hole 18, so that under the action of the fastening bolt 15, the clamping plate 16 and the ear plate are fastened to the clamping bracket 7, and the ear plate is supported on the upper part of the bracket 7, so as to realize the stable installation of the silo 1 and provide support for adjusting the position of the silo 1 relative to the bracket 7 according to the demand.

[0050] like Fig.13 As shown, in order to stably install the bracket 7 on the workplace, a sleeve plate 71 is sleeved on the end of the bracket 7. The sleeve plate 71 is buckled on the bracket 7 and can be connected to the installation area by bolts.

[0051] When the device of this embodiment is put into use, multiple devices can be equipped according to needs, and multiple devices can be arranged side by side at a high place in the installation site, and a platform can be built at a high place so that workers can walk on the platform to facilitate the filling of the device with spinning fluid. In order to prevent the spinning fluid from condensing in the silo 1, multiple groups of heating wires can be installed on the outside of the silo 1 according to needs. The heating wires are distributed in a spiral shape. Therefore, the temperature of the spinning fluid can be maintained under the action of the heating wires to make it molten.

[0052] Example 2

[0053] like Figure 3 , Figure 6 As shown, on the basis of Example 1, in order to be able to control the output of the spinning fluid from the silo 1, an extrusion component 3 is provided on the silo 1. The extrusion component 3 is installed on the frame 11, and the bottom of the extrusion component 3 can be extended into the silo 1. Therefore, under the action of the extrusion component 3, the spinning fluid can be squeezed and output from the outlet 12 of the silo 1 to form fiber filaments.

[0054] like Figure 6As shown, specifically, the extrusion assembly 3 includes an extrusion plate 32, a telescopic cylinder 31 and a support plate 33. The extrusion plate 32 is arranged on the inner side of the silo 1 and installed at the bottom of the telescopic cylinder 31. At the same time, the shape is adapted to the shape of the silo 1, that is, the diameter of the top of the extrusion plate 32 is equal to the inner diameter of the silo 1, and the shape and size of the bottom are the same as the shape and size of the bottom of the inner space of the silo 1. Therefore, the extrusion plate 32 can not only extrude the spinning fluid in the middle and upper part of the silo 1 to move, but also force the spinning fluid at the bottom of the silo 1 to output. Two support plates 33 are distributed on both sides of the telescopic cylinder 31 (which can be set as an electric cylinder or a hydraulic cylinder, etc.), and the sleeve frame 34 fixed on the top is connected and sleeved on the telescopic cylinder 31 by bolts. Therefore, under the action of the support plate 33, the telescopic cylinder 31 is stably installed on the frame 11, providing support for controlling the lifting of the extrusion plate 32.
