Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spinneret cleaning, in particular to a spinneret for polypropylene yarn production which is easy to clean. Background Art
[0002] The spinneret is a precision component on a chemical fiber spinning machine. Its function is to transform the viscous polymer melt or solution into a thin stream with a specific cross-section through micropores, which is then solidified by a coagulation medium or coagulation bath to form filaments.
[0003] First, we need to remove the spinneret from the equipment. This process needs to be done carefully to avoid damaging the spinneret. Normally, the spinneret is cleaned by flushing. However, the internal structure of the spinneret is characterized by small holes, and cleaning is performed in an open space. This results in insufficient pressure when the air or water flows through these holes during the cleaning process. The silk thread can easily continue to remain inside the spinneret, resulting in incomplete cleaning and affecting normal use. Utility Model Content
[0004] 1. Technical issues to be resolved
[0005] In view of the deficiencies in the prior art, the utility model provides a spinneret for polypropylene yarn production that is easy to clean, and solves the technical problem that the internal structure of the spinneret is characterized by small holes, and cleaning is performed in an open space, which leads to insufficient pressure of air or water when passing through these holes during the cleaning process, and the silk threads can easily continue to remain inside the spinneret, resulting in incomplete cleaning and affecting normal use.
[0006] (II) Technical solution
[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:
[0008] A spinneret for polypropylene yarn production which is easy to clean comprises a fixed box and a spinneret body. A driving mechanism is arranged at the top of the fixed box, and the driving mechanism comprises a fixed plate and a hydraulic rod. A sealing sleeve is fixedly mounted on the side end of the fixed plate, and a flushing plate is rotatably mounted on the bottom end of the sealing sleeve. A supporting frame is fixedly mounted on the top of the fixed box, and two sliding blocks are slidably mounted on the top of the supporting frame.
[0009] Preferably: a reset rod is fixedly installed on the bottom end of each of the sliders, two grooves are opened on the top of the support frame, two drive boxes are fixedly installed on the top of the sealing sleeve, rollers are rotatably installed on the side ends of each of the drive boxes, a fixed seat is fixedly installed on the top of each of the flushing plates, a connecting pipe is fixedly installed on the top of each of the fixed seats, a ring is fixedly installed on the surface of each of the fixed seats, and an adsorption net is fixedly installed inside the fixed box.
[0010] (III) Beneficial effects
[0011] 1. Through the sealing sleeve and the surface of the spinneret body, the water flow can be gathered inside the sealing sleeve. While being continuously cleaned by the flushing plate, the water flow gathers inside the sealing sleeve and then is discharged through the holes of the spinneret body itself. The water flow is discharged with a certain pressure to ensure high-speed flushing and cleaning of the holes and the intensity of cleaning.
[0012] 2. By driving the hydraulic rod to extend and retract, the hydraulic rod drives the sealing sleeve to move upward, and at the same time the reset rod extends and retracts in the opposite direction. The reset rod applies an upward thrust to the slider, allowing the slider to slide upward inside the groove.

[0019] The embodiment of the present application provides a spinneret for polypropylene yarn production that is easy to clean, thereby effectively solving the problem that the internal structure of the spinneret is characterized by small holes. At the same time, cleaning is performed in an open space, which results in insufficient pressure when the air flow or water flows through these holes during the cleaning process. The silk threads can easily continue to remain inside the spinneret, resulting in incomplete cleaning and affecting normal use. Through the sealing sleeve and the surface of the spinneret body being fitted together, the water flow can be gathered inside the sealing sleeve. While the flushing plate is continuously cleaning, the water flow gathers inside the sealing sleeve and is then discharged through the holes of the spinneret body itself. The water flow is discharged with a certain pressure, thereby ensuring high-speed flushing and cleaning of the holes and ensuring the intensity of the cleaning.
[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the problem that the internal structure of the spinneret is characterized by small holes and the cleaning is performed in an open space. This results in insufficient pressure when the airflow or water flows through these holes during the cleaning process, and the silk threads are likely to continue to remain inside the spinneret, resulting in incomplete cleaning and affecting normal use. The overall idea is as follows:
[0021] In view of the problems existing in the prior art, the utility model provides a spinneret for polypropylene yarn production that is easy to clean, comprising a fixed box 1 and a spinneret body 21. A driving mechanism is arranged at the top of the fixed box 1, and the driving mechanism comprises a fixed plate 13 and a hydraulic rod 17. A sealing sleeve 14 is fixedly installed at the side end of the fixed plate 13, and a flushing plate 26 is rotatably installed at the bottom end of the sealing sleeve 14. A support frame 12 is fixedly installed at the top of the fixed box 1, and two sliders 19 are slidably installed at the top of the support frame 12. The hydraulic rod 17 is driven by a motor. The hydraulic rod 17 moves downward to move, driving the sealing sleeve 14 to move downward. The sealing sleeve 14 squeezes the top of the spinneret body 21 downward, pushing the spinneret body 21 to move upward and get stuck in the interior of the support frame 12. At the same time, the spinneret body 21 moves downward to drive the slider 19 to move synchronously. The slider 19 squeezes the top of the reset rod 18, forcing the reset rod 18 to compress downward. At the same time, the spinneret body 21 moves to be flush with the top of the support frame 12, and the end of the sealing sleeve 14 fits tightly with the top of the spinneret body 21.
[0022] A reset rod 18 is fixedly installed at the bottom end of each slider 19, two grooves 22 are provided at the top of the support frame 12, two drive boxes 15 are fixedly installed at the top of the sealing sleeve 14, and a roller 16 is rotatably installed on the side end of each drive box 15, and a fixed seat 24 is fixedly installed at the top of each flushing plate 26, and a connecting pipe 23 is fixedly installed at the top of each fixed seat 24. The flushing plate 26 is driven to rotate at a uniform speed inside the sealing sleeve 14 to clean the surface of the spinneret body 21. At the same time, since the sealing sleeve 14 fits the surface of the spinneret body 21, the water flow can be gathered inside the sealing sleeve 14. While the flushing plate 26 continuously cleans, the water flow gathers inside the sealing sleeve 14 and is then discharged through the holes of the spinneret body 21 itself. A ring 25 is fixedly installed on the surface of each fixed seat 24, and an adsorption net 11 is fixedly installed inside the fixed box 1.
[0023] Working principle:
[0024] The first step is to move the spinneret body 21 to fit the side ends of the spinneret body 21 with the two sliders 19. The inner sides of the two sliders 19 are arc-shaped, and the slider 19 itself is L-shaped. The spinneret body 21 is positioned by the two sliders 19, and the side ends of the spinneret body 21 fit with the inner sides of the support frame 12. The hydraulic rod 17 is driven by the motor to retract and retract. The hydraulic rod 17 moves downward, driving the sealing sleeve 14 to move downward. The sealing sleeve 14 squeezes the top of the spinneret body 21 downward, pushing the spinneret body 21 to move upward and snap into the interior of the support frame 12. At the same time, the spinneret body 21 moves downward to drive the slider 19 to move synchronously, and the slider 19 squeezes the top of the reset rod 18, forcing the reset rod 18 to compress downward. At the same time, the spinneret body 21 is flush with the top of the support frame 12 after moving, and the end of the sealing sleeve 14 fits tightly with the top of the spinneret body 21. The pressure pump is connected to one end of the connecting pipe 23 to guide the water flow into the interior of the connecting pipe 23.
[0025] In the second step, the connecting pipe 23 and the flushing plate 26 are interconnected, and the water flows into the inside of the flushing plate 26. A plurality of nozzles are provided at the bottom end of the flushing plate 26, and the roller 16 is driven to rotate by the driving box 15. The roller 16 fits with the collar 25, driving the fixing seat 24 to rotate at the top of the sealing sleeve 14, driving the flushing plate 26 to rotate at a uniform speed inside the sealing sleeve 14, and cleaning the surface of the spinneret body 21. At the same time, since the sealing sleeve 14 fits with the surface of the spinneret body 21, the water flow can be gathered inside the sealing sleeve 14. While the flushing plate 26 continuously cleans, the water flow gathers inside the sealing sleeve 14, and then passes through the spray The holes of the spinneret body 21 itself are discharged, and the water flow is discharged with a certain pressure to ensure high-speed flushing and cleaning of the holes. An adsorption net 11 is installed inside the fixed box 1 to adsorb and filter the impurities flushed out of the spinneret body 21. After cleaning, the hydraulic rod 17 is driven to extend and retract, so that the hydraulic rod 17 drives the sealing sleeve 14 to move upward, and the reset rod 18 is extended and retracted in the opposite direction. The reset rod 18 applies an upward thrust to the slider 19, allowing the slider 19 to slide upward inside the groove 22. The slider 19 moves upward, driving the spinneret body 21 to move upward, allowing the spinneret body 21 to leave the inside of the support frame 12, so as to facilitate material collection.
[0026] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
