Description

Technical Field

[0001] The utility model belongs to the technical field of spinning equipment, and in particular relates to an improved spinning box. Background Art

[0002] The spinning fluid is squeezed out from the capillaries of the spinneret or spinneret continuously, quantitatively and evenly by a metering pump to form a liquid stream; and then solidified into filaments in air, water or a coagulation bath is called spinning or fiber forming. The melt spinning method is mostly used in the spinning method. Melt spinning is a chemical spinning method in which the polymer is heated and melted, extruded through a spinneret, and cooled and solidified in the air to form fibers.

[0003] After the heated molten polymer is spun into fibers, it needs to be cooled and solidified in the spinning box. Usually, cold air is introduced into the spinning box or the box is cooled, so the overall temperature of the side walls of the box is relatively low. Since the surface temperature of the filaments just squeezed into fibers from the spinneret is still very high, the heat emitted will form condensed water on the inner wall of the spinning box. If these condensed waters are not discharged in time, if they are attached too much, they will flow to the bottom of the box and gather. Once the filaments float and are contaminated by the accumulated liquid, the solid shape of the filaments will be affected. Utility Model Content

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] Example 1

[0050] An improved spinning box, comprising: a spinning box 1, a refrigeration component, and a condensed water drainage component;

[0051] like Figure 1 As shown, a plurality of spinnerets 2 are arranged on the top surface of the spinning box 1, a feed pipe is arranged above each spinneret 2, and the plurality of feed pipes are gathered into a main feed pipe, and the main feed pipe is connected to the screw extruder; a metering pump 3 is arranged on the main feed pipe; the molten polymer is output through the screw extruder, and the metering pump 3 pumps the molten polymer into the spinneret 2 in a quantitative manner, and the molten polymer is extruded through the small holes on the spinneret 2 to form a molten stream, that is, a filamentary fiber.

[0052] Since the above-mentioned filamentary fibers are high-temperature melts that have just been ejected from the spinneret 2, the surface temperature of the filamentary fibers has not completely dropped. Therefore, a low-temperature environment needs to be created in the spinning box 1 so that the above-mentioned filamentary fibers can be quickly cooled and shaped in the low-temperature environment to complete spinning; the cooled and shaped filamentary fibers are output from the spinning outlet 4 opened in the center of the bottom of the spinning box 1 and arrive at the winding equipment for winding the filamentary fibers.

[0053] Typically, a low temperature environment is created in the spinning box 1 by introducing cold air into the spinning box 1; Figure 1 As shown, a cold air inlet 6 is provided on the side wall of the spinning box 1 and at an upper position, and the cold air inlet 6 connects the inside of the spinning box 1 with the external environment; a cold air duct is connected to the cold air inlet 6, and cold air is poured into the box to create a low-temperature environment inside the box.

[0054] The surface temperature of the filamentary fiber just ejected from the spinneret 2 is relatively high, and the emitted hot air touches the side wall of the box. Under the action of the temperature difference, the hot air will form condensed water on the side wall of the box; when too much condensed water is attached, it will flow along the side wall of the box to the bottom of the box and gather at the bottom; the gathered condensed water will also flow out along the spinning outlet and adhere to the filamentary fiber, which will affect the quality of the filamentary fiber.

[0055] Therefore, in this embodiment, a condensate drainage assembly is provided inside the spinning box 1 to drain the condensate. The above-mentioned condensate drainage assembly includes: a side wall drainage groove 9 and a bottom drainage groove 11; the side wall drainage groove 9 is provided on the side wall of the spinning box 1, and the side wall drainage groove 9 can be provided as a vertical groove structure for vertical drainage, or a plurality of side wall drainage grooves 9 can be provided according to the size of the side wall of the spinning box to increase the drainage amount; the bottom drainage groove 11 is provided at the bottom of the spinning box 1; the side wall drainage groove 9 is communicated with the bottom drainage groove 11; the bottom drainage groove 11 is communicated with the drainage port 12 provided at the bottom of the spinning box 1;

[0056] The condensed water attached to the side wall of the spinning box 1 flows to the bottom drainage groove 11 on the bottom surface of the box through the side wall drainage groove 9, and then the condensed water is discharged from the drainage port 12 through the bottom drainage groove 11. The side wall drainage groove 9 can prevent the condensed water from adhering to the side wall and flowing randomly. Under the action of the drainage groove, the condensed water flows into the bottom drainage groove 11 along a fixed path, making the drainage regular.

[0057] The above-mentioned side wall drainage groove 9 can only drain the condensed water attached to the side wall of the spinning box. The condensed water attached to the top of the spinning box 1 cannot be drained by the groove structure. Therefore, in this embodiment, a moisture absorption box is detachably provided on the top of the spinning box 1 by pasting or snapping. Dehumidifying materials are placed in the moisture absorption box. The condensed water attached to the top of the spinning box can be absorbed by the moisture absorption box. In this way, the condensed water on the top of the spinning box can be prevented from dripping.

[0058] Example 2

[0059] Based on Example 1, in Example 1, the side wall drainage groove 9 is vertically opened on the inner wall of the spinning box 1, and the condensed water entering the side wall drainage groove 9 will flow vertically down along the groove body, but the side wall condensation grooves 9 are independent of each other, that is, the side wall condensation grooves 9 and the bottom drainage grooves 11 are collected through multi-point dispersion; and because the side wall condensation grooves 9 are vertically arranged, the condensed water that does not enter the side wall condensation grooves 9 can only flow down along the side wall and cannot smoothly enter the side wall condensation grooves 9.

[0060] In this embodiment, two rows and two columns of side wall drainage grooves 9 are opened on the side wall of the spinning box; a collecting groove 10 is opened in the middle of the two columns of side wall drainage grooves 9; the opposite ends of the two side wall drainage grooves 9 on each row are connected to the collecting groove 10; the condensed water drained into the side wall drainage grooves 9 will be gathered in the collecting groove 10, and will flow from the collecting groove 10 to the bottom drainage groove 11.

[0061] The side wall drainage grooves 9 on the side walls of the spinning box 1 are horizontally opened and arranged in two rows. The distribution design of several rows can fill the side walls as much as possible. The condensed water attached to the side walls of the spinning box will enter the side wall drainage grooves 9 in the process of flowing along the side walls. This can prevent the condensed water from being unable to enter the groove and flowing directly along the side walls. The condensed water drained from the side wall condensation grooves 9 is finally collected in the collecting grooves 10, and is uniformly drained from the collecting grooves 10 to the bottom drainage grooves 11, thereby improving the drainage efficiency.

[0062] like Figure 2 As shown, as a preferred embodiment, the bottom drainage groove 11 is configured as a multi-ring annular groove body; the multi-ring annular groove bodies are connected; the outermost ring annular groove body is connected to the bottom of the collecting groove 10. The bottom drainage groove 11 is configured as a plurality of interconnected annular groove structures, which also occupy most of the bottom surface except the spinning outlet, increase the drainage channel, and improve the drainage amount.

[0063] Example 3

[0064] Based on Example 2, in Example 2, the side wall drainage groove 9 is horizontally opened, so that the condensed water flowing along the side wall of the spinning box 1 can enter the side wall drainage groove 9. The condensed water in the side wall drainage groove 9 can only enter the collecting groove 10 after natural flow, which will cause the problem of too slow drainage efficiency.

[0065] like Figure 2 As shown, in this embodiment, the two side wall drainage grooves 9 in the same row are both arranged to be inclined; and the low points of the two side wall drainage grooves 9 in the same row are both connected to the collecting groove 10 at one end.

[0066] The inclined side wall drainage groove 9 has a slope, and the low point of the slope is connected to the collecting groove 10; the condensed water entering the side wall drainage groove 9 will quickly flow into the collecting groove 10 along the groove body under the slope condition, and then be uniformly drained by the collecting groove 10 to the bottom drainage groove 11. Therefore, the inclined side wall drainage groove 9 can improve the drainage efficiency.

[0067] Example 4

[0068] Based on Example 1, in Example 1, a cold air port 6 is provided on the side wall of the spinning box 1, and cold air is introduced into the spinning box 1 through the cold air port 6, so that a low-temperature environment is formed in the spinning box 1; the low-temperature environment is used to assist the filamentary fibers to quickly cool and set. However, as the spinning process proceeds, the heat emitted by the filamentary fibers will cause the temperature in the spinning box to rise, and the temperature rises, and the cooling effect on the filamentary fibers is not obvious. If the temperature in the spinning box is not adjusted in time, the cooling and setting effect of the filamentary fibers will be affected.

[0069] like Figure 1 As shown, in this embodiment, a refrigeration semiconductor 7 and a temperature sensor 8 are arranged in the spinning box 1; the temperature sensor 8 and the refrigeration semiconductor 7 are both communicatively connected to the PLC;

[0070] The temperature sensor 8 is used to monitor the low-temperature environment temperature in the spinning box 1 and transmit the monitoring data to the PLC in real time. The PLC determines whether it is necessary to control the refrigeration semiconductor 7 to adjust the temperature in the box to the set threshold range based on the real-time temperature monitoring data.

[0071] When the temperature sensor 8 detects that the real-time temperature in the spinning box 1 rises and exceeds the threshold, the temperature sensor 8 feeds the monitoring information into the PLC. After the PLC processes the temperature information, it issues a control instruction to the refrigeration semiconductor 7 to start the refrigeration semiconductor 7 to work until the refrigeration semiconductor 7 adjusts the temperature in the spinning box 1 to the set low temperature threshold. In this way, the temperature in the spinning box 1 can be kept at a constant low temperature, ensuring the cooling and solidification effect of the filamentary fibers.

[0072] Example 5

[0073] Based on Example 1, which is mainly used for melt spinning process, it is necessary to create a low-temperature cooling environment in the spinning box 1; in this embodiment, a hot air port 5 is provided below the side wall of the spinning box 1 and on the opposite side of the cold air port 6. The purpose is to enable the spinning box 1 in this embodiment to be used for dry spinning.

[0074] Dry spinning is a type of solution spinning. The fiber-forming polymer is dissolved in a solvent with a low boiling point and good solubility to form a spinning solution. At this time, the spinning solution can be spit out from the small holes of the spinneret and enter the heated gas. The solvent in the spinning solution evaporates and the polymer filaments gradually solidify. After post-processing such as stretching, shaping, washing, and drying, the finished fiber can be obtained.

[0075] Therefore, the spinning box 1 in this embodiment needs to introduce hot air with a relatively high temperature into the box from the hot air port 5. As the hot air in the box increases, the cold air in the box will be gradually discharged from the cold air port 6. Finally, when the box is filled with hot air, the temperature in the box is increased, so as to meet the purpose of dry spinning.

[0076] As a preferred embodiment, Figure 3 As shown, a detachable insulation layer 13 is provided on the inner wall of the spinning box 1. The insulation layer 13 can be made of materials such as ceramic fiber and aluminum silicate. In addition, a plurality of dense small holes are provided on the insulation layer 13 to enhance the insulation effect.
