Description

Technical Field

[0001] This utility model relates to the technical field of polyester filament spinneret setting device, and specifically to a polyester filament spinneret setting device. Background Technology

[0002] Polyester yarn is characterized by its resistance to chemicals and frequent washing, reducing fading and discoloration of clothing. Therefore, it is used to manufacture hotel uniforms, stonewashed denim clothing, sportswear, and children's clothing. The polyester yarn spinning device is an indispensable and important piece of equipment in the polyester yarn production process. After the polyester yarn is spun out of the spinning device, it usually needs to be cooled and shaped first, and then heat-shaped.

[0003] After completing the spinning operation, some existing spinning devices typically use multiple airflows of different temperatures to cool and shape the polyester filaments. Due to the blowing of the airflow onto the polyester filaments, the unshaped polyester filaments may be subjected to an external force, affecting their shaping effect. Furthermore, the flow of gas may cause harmful gases emitted by the polyester filaments before cooling to escape, thereby affecting the health of the device users. Utility Model Content

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to an embodiment of the present invention, a polyester filament spinning and shaping device is provided, comprising: a plurality of liquid storage cylinders 1, which are arranged in two groups opposite to each other, and adjacent liquid storage cylinders 1 are fixedly connected; a discharge port 2 and a liquid inlet 3 are connected from top to bottom on the outer wall of the liquid storage cylinder 1; a sealing member 7 is provided in the bottom opening of the liquid storage cylinder 1 to seal the gap between the polyester filament and the inner wall of the bottom opening of the liquid storage cylinder 1; and a liquid storage tank 5 is fixedly installed on the bottom side of the plurality of liquid storage cylinders 1.

[0029] Air pump 6 is fixedly installed on the outer wall of the top of liquid storage tank 5, and its air inlet is inserted into liquid storage tank 5.

[0030] The liquid injection mechanism 4 is located between the liquid storage tank 5 and several liquid inlets 3, and is used to inject water from the liquid storage tank 5 into the liquid inlets 3.

[0031] The reflux mechanism 8 is located on the liquid storage tank 5 and is used to guide the gas and liquid discharged from the outlet 2 into the liquid storage tank 5.

[0032] In this embodiment, when using the improved polyester filament spinneret and setting device, please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the polyester filaments ejected by the polyester filament spinneret fall directly into the liquid storage cylinder 1, and then are discharged from the liquid storage cylinder 1 through the bottom opening of the liquid storage cylinder 1. Finally, they pass through the inner hole of the liquid storage tank 5 and enter the subsequent processing device for further heat setting treatment of the polyester filaments.

[0033] During the process of the polyester filament passing through the liquid storage cylinder 1, the air pump 6 is started and the gas in the liquid storage tank 5 is drawn at a constant speed so that a negative pressure chamber is formed in the liquid storage tank 5. At this time, due to the pressure difference between the inside of the liquid storage tank 5 and the top opening of the liquid storage cylinder 1, the gas in the top opening of the liquid storage cylinder 1 flows into the liquid storage tank 5 through the discharge port 2 and the return mechanism 8 to replenish the gas lost in the liquid storage tank 5.

[0034] As the gas slowly leaks out of the top opening of the liquid storage tank 1, external gas continuously flows into the opening of the liquid storage tank 1 to replenish the gas leaking out of the top opening of the liquid storage tank 1. During the process of the external gas slowly flowing into the opening of the liquid storage tank 1, the polyester filaments can be pre-cooled. At the same time, the continuous flow of gas can carry the harmful gases emitted by the polyester filaments into the liquid storage tank 5. (The exhaust end of the air pump 6 is connected to a gas delivery pipe to transport the gas discharged by the air pump 6 to the corresponding location for discharge, such as the outdoor area of ​​the factory or the gas harmless treatment equipment) so as to prevent the harmful gases emitted by the polyester filaments from being released into the room and affecting the health of the users of the equipment.

[0035] At the same time as the air pump 6 starts, the liquid injection mechanism 4 starts, uniformly drawing water from the storage tank 5 and injecting water into the bottom of the storage cylinder 1 through the liquid inlet 3. When the water surface in the storage cylinder 1 moves to the outlet 2, due to the push of the gas in the top opening of the storage cylinder 1, the excess water in the storage cylinder 1 passes through the outlet 2 and flows back into the storage tank 5 for reuse through the return mechanism 8. In the process of gas flow and water mixing, the heat of the water can be continuously removed, and the water can be cooled to a certain extent. The water vapor emitted by the water evaporation in the storage tank 5 is also removed, so as to cool the water in the storage tank through water evaporation.

[0036] Based on the above-mentioned liquid storage cylinder 1, a continuous and slow water flow is formed from bottom to top. Combined with the movement of polyester filaments from top to bottom in the liquid storage cylinder 1, the temperature of the water stored in the liquid storage cylinder 1 is gradually reduced from top to bottom, thereby performing a stable graded cooling treatment on the polyester filaments. The cooling and shaping effect of the polyester filaments is better, and the influence of external forces on the shaping of the polyester filaments can be greatly avoided.

[0037] It should be noted that a cooling structure can be installed inside the liquid storage tank 5 to lower the temperature of the water stored in the liquid storage tank 5, thereby further enhancing the cooling and shaping effect of the polyester filaments and reducing the water loss rate during device operation.

[0038] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the liquid storage tank 5 has a ring-shaped top view, and the sealing component 7 is located on the top side of the inner hole of the liquid storage cylinder 1. The inner bottom wall of the liquid storage tank 5 is a sloping surface that curves upward from all sides towards the center. Two electrically controlled valves 9 are fixedly connected to the outer wall of the bottom of the liquid storage tank 5, and the interior of each electrically controlled valve 9 is connected to the interior of the liquid storage tank 5.

[0039] In this embodiment, please refer to Figure 1 and Figure 2As shown, during the use of the device, the external water supply equipment injects water into the storage tank 5 at a constant speed through one of the electrically controlled valves 9 to replenish the water lost in the storage tank 5. (One of the electrically controlled valves 9 is connected to the water supply interface of the external water supply equipment through the water inlet pipe, and the other electrically controlled valve 9 is connected to the water inlet interface of the external water treatment equipment through the drainage pipe).

[0040] After the device is used, another electrically controlled valve 9 is opened, and the water in the water storage tank is discharged from the electrically controlled valve 9. Due to the impact of the water flow on the inclined inner bottom wall of the liquid storage tank 5, the debris at the bottom of the liquid storage tank 5 is discharged along with the water flow.

[0041] It should be noted that the device can be automatically controlled by an external control computer to enhance its level of automation.

[0042] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 3 As shown, an arc-shaped plate 10 is provided inside the liquid storage cylinder 1 at the position corresponding to the discharge port 2, and both sides of the arc-shaped plate 10 are fixedly connected to the inner wall of the corresponding liquid storage cylinder 1 through connecting rods.

[0043] In this embodiment, please refer to Figure 2 and Figure 3 As shown, due to the obstruction of the arc plate 10, the air on the outer periphery of the polyester filament will not move directly into the discharge port 2, which can greatly reduce the lateral flow rate of the air on the outer periphery of the polyester filament, thereby further avoiding the influence of airflow on the polyester filament.

[0044] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the liquid injection mechanism 4 includes two water pumps 41, which are fixedly installed on the top side of the liquid storage tank 5. The inlet end of the water pump 41 is connected to the inside of the liquid storage tank 5 through the conduit 45. The bottom end of the conduit 45 extends to the bottom of the air pump 6. The outlet end of the water pump 41 is connected to a diversion pipe 42, and the inlet end of the liquid inlet 3 is fixedly inserted into the corresponding diversion pipe 42.

[0045] In this embodiment, please refer to Figure 2 and Figure 4As shown, when the device is in use, the water pump 41 starts and continuously draws water from the storage tank 5 through the conduit 45. (The storage tank 5 is equipped with a water level sensor, which controls the opening and closing of the corresponding electronically controlled valve 9, so that the water level in the storage tank 5 is always between the bottom opening of the conduit 45 and the air inlet of the air pump 6.) The water drawn by the water pump 41 is injected into the diversion pipe 42, and then flows into the storage cylinder 1 from the inlet, so that the water in the storage cylinder 1 always flows slowly from bottom to top, so as to constantly refresh the water in the storage cylinder 1 and avoid the water temperature in the storage cylinder 1 from becoming too high. At the same time, the water temperature in the storage cylinder 1 gradually decreases from top to bottom.

[0046] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 4 As shown, a constraint cylinder 43 is fixedly installed at the bottom of the liquid storage cylinder 1, and the interior of the constraint cylinder 43 is connected to the interior of the corresponding liquid inlet 3. A mesh plate 44 is fixedly installed at the bottom of the liquid storage cylinder 1, and the bottom opening of the constraint cylinder 43 is fixedly inserted through the corresponding mesh plate 44.

[0047] In this embodiment, please refer to Figure 4 As shown, the water flowing into the storage cylinder 1 from the inlet 3 first flows into the constraint cylinder 43, and then is guided by the constraint cylinder 43 to the bottom of the mesh plate 44. Finally, it flows upward through the holes of several mesh plates 44. The flow rate of the water at the bottom of the storage cylinder 1 can be greatly reduced by the diversion of the water, thereby greatly reducing the impact of the water flow injected into the storage cylinder 1 on the polyester filament.

[0048] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the sealing component 7 includes a flexible tube 71, both ends of which are fixedly inserted through the bottom opening of the corresponding mesh plate 44 and the corresponding liquid storage cylinder 1, and both openings are flared. The inside of the flexible tube 71 is hollow and filled with air. A sleeve 72 is fixedly fitted on the outer periphery of the flexible tube 71, and both ends of the sleeve 72 are fixedly connected to the inner bottom wall of the corresponding mesh plate 44 and the corresponding liquid storage cylinder 1, respectively.

[0049] In this embodiment, please refer to Figure 2 and Figure 4 As shown, the water flowing at a faster speed below the mesh plate 44 will not directly impact the polyester filaments due to the obstruction of the sleeve 72. This avoids the faster-flowing and laterally flowing water directly contacting the polyester filaments and applying an impact force to them, thus affecting the shaping effect of the polyester filaments.

[0050] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 4As shown, the reflux mechanism 8 includes several connecting pipes 81, one end of which is threaded onto the discharge end of the corresponding discharge port 2. A sieve plate 82 is fixedly installed at the bottom of the liquid storage tank 5, and the other end of the connecting pipe 81 extends to the bottom of the sieve plate 82 and is fixedly connected to the liquid storage cylinder 1 and the sieve plate 82.

[0051] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 4 As shown, the gas and water discharged from the outlet 2 are directly guided by the connecting pipe 81 to the bottom of the sieve plate 82 and discharged into the storage tank 5. Then, the water flows upward through the holes of the sieve plate 82 and mixes with the water in the storage tank 5, while the gas flows upward through the holes of the sieve plate 82 and finally emerges from the water in the storage tank 5 and is sucked up by the air pump 6. Impurities in the return water and gas are intercepted by the sieve plate 82 and stored in the water at the bottom of the storage tank 5 to avoid the water in the storage cylinder 1 containing too many impurities from affecting the cooling and shaping effect of the polyester yarn.

[0052] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0053] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
