Description

Technical Field

[0001] This utility model relates to the field of electronic yarn drawing machine technology, specifically to a nozzle coolant circulation system for electronic yarn drawing equipment. Background Technology

[0002] Electronic yarn drawing equipment is a key piece of equipment used in the production of electronic yarn. Its main function is to draw molten glass into fiber monofilaments, which are then twisted and processed to form electronic yarn. In the production process of electronic yarn, the nozzle is a crucial component for drawing the high-temperature molten glass into fibers. Therefore, it is necessary to maintain an appropriate temperature to ensure the quality of the glass fibers. The nozzle cooling fluid circulation system of the electronic yarn drawing equipment is a specially designed system for controlling and regulating the temperature of the cooling fluid during the drawing process, ensuring the stability of the drawing process and product quality.

[0003] However, in current technologies, when cooling the nozzle of an electronic yarn drawing machine, the coolant is often split and throttled to ensure the cooling effect. The sinking coolant is circulated directly without passing through a heat exchanger. However, when the split and throttled coolant re-enters the circulation, the overall flow rate of the coolant increases. When the original flow rate of the coolant is already set to be fast, this structure will cause the rapidly flowing coolant to carry away more heat, resulting in the nozzle temperature being too low and affecting the yarn drawing effect. Utility Model Content

[0004] The purpose of this invention is to provide a coolant circulation system for the nozzle of an electronic yarn drawing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A coolant circulation system for the nozzle of an electronic yarn drawing device includes a nozzle on the drawing device and a heat exchanger and a liquid guide pipe in the nozzle cooling system. A return pipe is provided at one end of the nozzle, and an adjustment component for controlling the temperature of the nozzle cooling is provided on the extension path of the return pipe. The adjustment component includes a flow-blocking frame provided at one end of the return pipe, and two branch pipes provided at the other end of the flow-blocking frame. A transfer frame is provided outside the two branch pipes.

[0007] The transfer frame is equipped with an inner tube, and the inner tube is equipped with two guide grooves. One of the guide grooves is equipped with a turntable on one side. The turntable has a through hole at one end and a cavity at the other end. The cavity is equipped with an electromagnet and a protrusion. One end of the protrusion is equipped with a magnetic plate.

[0008] As a preferred embodiment of this utility model, one end of the return pipe is connected to the infusion tank inside the leak nozzle, and the other end is connected to the intercepting frame. One end of each of the two branch pipes is connected to the two outlets of the intercepting frame, and the other end of each branch pipe passes through the transfer frame.

[0009] As a preferred embodiment of this utility model, the coolant temperatures in the two branch pipes are different, wherein one end of the branch pipe with a higher coolant temperature extends through the heat exchanger, and the other end of the branch pipe with a lower coolant temperature skips the heat exchanger and connects to the liquid guide pipe.

[0010] As a preferred embodiment of this utility model, the inner tube is located inside the transfer frame and is embedded and connected to the interior of the transfer frame. The inner tube has a hollow structure, and the external guide groove corresponds to two branch tubes.

[0011] As a preferred embodiment of this utility model, the turntable is located in the inner tube near the branch pipe corresponding to the high-temperature liquid in the inner tube and is rotatably connected to the inner wall of the inner tube through a connecting shaft. The other branch pipe corresponding to the low-temperature liquid is provided with an annular partition outside the guide groove, and a control valve is provided inside the partition.

[0012] As a preferred embodiment of this utility model, the through hole and cavity on the outside of the turntable correspond to the guide groove by rotation, the protrusion is located in the cavity and is slidably connected to the inner wall of the cavity, and the electromagnet is magnetically connected to the magnetic plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Addressing the problems raised in the background art, this application employs an adjustment component. By real-time detection of the leak nozzle temperature and placing a transfer frame on the coolant branch pipe, the low-temperature and high-temperature coolants are transported through the transfer frame. Through the partition within the transfer frame, the low-temperature and high-temperature coolants are normally diverted and transported. When the leak nozzle temperature is too low, the output rate of the high-temperature liquid in the transfer chamber can be closed or reduced, while simultaneously opening the partition valve to allow the high-temperature liquid to mix into the low-temperature liquid's transport pipe. This mixing increases the coolant temperature, and when the coolant circulates through the heat exchanger and converges, the coolant temperature increases, thereby reducing the cooling effect on the leak nozzle. This gradually brings the leak nozzle temperature back to the set range, achieving temperature regulation and control of the leak nozzle, ensuring the leak nozzle temperature remains within a stable range, and improving the stability of wire drawing.

[0014] This invention enables the transfer of coolant during the interception and return process, and adjusts the temperature of the coolant as it passes through the nozzle by controlling the nozzle temperature, thereby controlling the cooling effect, improving the stability of the nozzle temperature and the stringing effect.

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the present utility model embodiments. Example

[0022] Please see Figure 1-5 This utility model provides a technical solution: a coolant circulation system for the nozzle of an electronic yarn drawing device, including a nozzle on the drawing device and a heat exchanger and a liquid guide pipe in the nozzle cooling system. One end of the nozzle is provided with a return pipe 1 for circulating the coolant after it has been cooled by the nozzle. An adjustment component for controlling the temperature of the nozzle cooling is provided on the extension path of the return pipe 1. The adjustment component includes a flow-blocking frame 2 at one end of the return pipe 1, which divides the coolant by a splitting plate, so that the rising hot liquid and the sinking low-temperature liquid are separated and transported to two branch pipes 3 respectively. The other end of the flow-blocking frame 2 is provided with two branch pipes 3 for transporting low-temperature and high-temperature coolant respectively. Both streams of coolant are transported through a transfer frame 4. A transfer frame 4 is provided outside the two branch pipes 3.

[0023] The transfer frame 4 has an inner tube 5 inside, which improves the sealing effect of the coolant through a double-layer structure to prevent leakage. The inner tube 5 has two guide grooves 501 inside, which are used to guide and limit the angle of the two coolant streams. The partition inside the inner tube 5 also prevents the liquid from mixing in the inner tube 5. One side of one of the guide grooves 501 has a turntable 6. One end of the turntable 6 has a through hole 601, and the other end has a cavity 602. The cavity 602 has an electromagnet 7 and a protrusion 8 inside. One end of the protrusion 8 has a magnetic plate 801. The turntable 6 rotates in the inner tube 5 to switch between the through hole 601 and the cavity 602 and the corresponding high-temperature guide groove 501. The protrusion 8 can block the cavity 602 when it is connected to the guide groove 501.

[0024] During operation, the temperature of the leak needs to be monitored in real time by a temperature sensor. When the temperature of the leak is lower than the set range, the turntable 6 can be controlled to rotate and block the corresponding high-temperature guide groove 501, so that the high-temperature liquid transported in the branch pipe 3 remains in the transfer frame 4. At the same time, the control valve in the external partition of another guide groove 501 is opened, so that the high-temperature liquid flows into the low-temperature liquid branch pipe 3 and mixes with the low-temperature liquid, and is transported to the liquid guide pipe along with the low-temperature liquid flow, increasing the temperature of the coolant in the liquid guide pipe. As the temperature of the coolant rises, the cooling effect on the leak will decrease. During operation, the leak temperature gradually rises and recovers due to the decrease in cooling effect. After recovery, the transfer frame 4 is reset, thus realizing the control and regulation of the leak temperature.

[0025] During operation, the pump drives the coolant to flow from the storage tank into the guide pipe and into the leak to cool the leak. The coolant flowing out of the leak passes through the return pipe 1, the cut-off frame 2 and the branch pipe 3 in sequence and is then transported to the heat exchanger. The coolant entering the heat exchanger is discharged into the guide pipe, while another part of the low-temperature liquid directly enters the guide pipe and is then transported back into the leak, and the cycle repeats.

[0026] In this embodiment, all electrical components are controlled by a conventional controller.

[0027] For an example, please refer to... Figure 1-5One end of the return pipe 1 is connected to the liquid inlet tank inside the leak, and the other end is connected to the intercepting frame 2. One end of each of the two branch pipes 3 is connected to one of the two outlets of the intercepting frame 2, and the other end passes through the transfer frame 4. The coolant temperatures in the two branch pipes 3 are different. One end of the branch pipe 3 with the higher liquid temperature extends through the heat exchanger, while the other end of the branch pipe 3 with the lower liquid temperature skips the heat exchanger and connects to the liquid guide pipe. The inner pipe 5 is located inside the transfer frame 4 and is embedded within the transfer frame 4. The inner pipe 5 has a hollow structure, and the external guide pipe... The guide groove 501 corresponds to two branch pipes 3. The turntable 6 is located in the inner pipe 5 near the branch pipe 3 with high temperature liquid, corresponding to the guide groove 501 area, and is rotatably connected to the inner wall of the inner pipe 5 through a connecting shaft. The other branch pipe 3 corresponding to low temperature liquid has an annular partition outside the guide groove 501, and a control valve is installed inside the partition. The through hole 601 and cavity 602 outside the turntable 6 are switched to correspond to the guide groove 501 by rotation. The protrusion 8 is located in the cavity 602 and is slidably connected to the inner wall of the cavity 602. The electromagnet 7 is magnetically connected to the magnetic plate 801. In operation, the coolant is first driven by the pump to extend from the reservoir and be delivered to the leak through the guide pipe. It then circulates through the return pipe 1, the throttling frame 2, the branch pipe 3, and the heat exchanger. Simultaneously, the sensor detects the temperature of the leak. When the leak temperature is below the set range, the turntable 6 inside the transfer frame 4 on the branch pipe 3 is rotated. This causes the cavity 602 area inside the turntable 6 to switch to correspond with the guide groove 501, sealing the high-temperature liquid and controlling the opening of the control valve in the partition. This allows the high-temperature liquid to flow into the low-temperature liquid branch pipe 3 and mix with the low-temperature liquid. The high-temperature liquid then flows with the low-temperature liquid branch pipe 3 and is delivered to the guide pipe, where it mixes with the coolant that has passed through the heat exchanger, increasing the coolant temperature and reducing the cooling effect on the leak, thus raising the leak temperature to the set range.

[0028] The working process of this utility model is as follows: During use, the coolant is first driven by the pump to extend from the storage tank and be transported to the leak nozzle through the guide pipe. It then circulates through the return pipe 1, the intercepting frame 2, the branch pipe 3, and the heat exchanger. Simultaneously, a sensor detects the temperature of the leak nozzle. When the leak nozzle temperature is below the set range, the turntable 6 inside the transfer frame 4 on the branch pipe 3 rotates, causing the cavity 602 area within the turntable 6 to switch to correspond with the guide groove 501. This seals the high-temperature liquid and controls the opening of the control valve within the partition, allowing the high-temperature liquid to flow into the low-temperature liquid branch pipe 3 and mix with it. The high-temperature liquid then flows with the low-temperature liquid branch pipe 3 and is transported to the guide pipe, mixing with the coolant that has passed through the heat exchanger, increasing the coolant temperature, reducing the cooling effect on the leak nozzle, and raising the leak nozzle temperature to the set range. This utility model achieves transfer during the coolant interception and return process, and adjusts the coolant temperature as it passes through the leak nozzle based on the leak nozzle temperature, thereby controlling the cooling effect, improving the stability of the leak nozzle temperature, and enhancing the stringing effect.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
