Description

Technical Field

[0001] This utility model relates to the field of cleaning technology for spinning equipment, and specifically to a cleaning medium supply mechanism. Background Technology

[0002] During the spinning process, high temperatures and the sublimation of some oligomers in the polymer melt produce white powder. This powder adheres to the spinneret of the spinning assembly. In addition, the silicone oil sprayed on the spinning spinneret before spinning cures and causes a lot of dirt to appear on the spinneret. This dirt will increase the number of broken ends and fuzz, affecting the production status. Therefore, the spinning spinneret must be cleaned after a period of time.

[0003] In existing technologies, silicone oil is used as the cleaning medium for cleaning spinnerets. A cleaning medium supply mechanism delivers compressed gas and silicone oil to a nozzle, which then sprays the oil onto the spinneret surface for cleaning. However, in existing technologies, silicone oil spraying alone cannot completely remove the dirt, requiring the use of a scraper to scrape the spinneret surface. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cleaning medium supply mechanism for conveying a cleaning medium different from the prior art to improve the cleaning effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The compressed gas supply mechanism is connected to the air inlet channel through an air inlet pipeline, and the outlet channel is connected to the main pipeline.

[0007] In some embodiments, the silicone oil supply mechanism includes an oil tank, an oil pump, an oil storage tank, and a nozzle for atomizing silicone oil.

The oil tank, the oil pump, the oil storage tank, and the oil inlet of the nozzle are sequentially connected through an oil inlet pipeline. The silicone oil supply mechanism also includes a motor for driving the oil pump, and the motor is connected to the oil pump.

[0008] In some embodiments, the silicone oil supply mechanism further includes a control valve for controlling the oil output of the nozzle, the control valve being integrated on the nozzle, or the control valve being disposed on the oil inlet line between the oil storage tank and the nozzle.

[0013] The feeding assembly includes a first feeding plate disposed on the hopper assembly, a second feeding plate disposed below the first feeding plate, and a distributing plate disposed between the first feeding plate and the second feeding plate. A feeding channel is formed between the first feeding plate, the distributing plate, and the second feeding plate. The distributing plate is rotatably disposed. When the distributing plate rotates, the feeding channel is unobstructed. When the distributing plate does not rotate, the feeding channel is blocked.

[0014] The base is fixedly connected to the lower part of the hopper assembly. The air inlet channel and the discharge channel are both provided on the base. The discharge channel is connected to the particle channel, and there is a gap between the inlet of the discharge channel and the outlet of the particle channel. The air intake of the air inlet channel creates a negative pressure in the gap.

[0015] In some embodiments, the first feeding plate is provided with a first feeding port penetrating its upper and lower end faces, the second feeding plate is provided with a second feeding port penetrating its upper and lower end faces, and the distributing plate is provided with a distributing port penetrating its upper and lower end faces. The first feeding port, the distributing port, and the second feeding port form the feeding channel. The position of the first feeding port and the position of the second feeding port are offset. The distributing plate can be rotated to make the position of the distributing port correspond to the position of the first feeding port or the second feeding port.

[0016] In some embodiments, the particle supply mechanism further includes a guide member disposed in the storage cavity and located below the second feeding plate. The guide member includes a disc body located at the upper part and a first column body disposed at the lower part of the disc body. The disc body has a conical structure that is larger at the top and smaller at the bottom.

Detailed Implementation

[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] In view of the problem that the existing technology cannot achieve a good cleaning effect when using silicone oil as a cleaning medium, this embodiment uses particles, silicone oil and compressed gas as the cleaning medium when cleaning the spinneret. This embodiment provides a supply mechanism for the cleaning medium to deliver the cleaning medium to the nozzle.

[0032] like Figure 1 and Figure 2As shown, the cleaning medium supply mechanism of this utility model includes a silicone oil supply mechanism, a particle supply mechanism, a compressed gas supply mechanism, and a main pipeline 4.

[0033] The silicone oil supply mechanism is used to atomize and deliver liquid silicone oil to main pipeline 4. Specifically, for example... Figure 1 and Figure 2 As shown, the silicone oil supply mechanism includes an oil storage tank 11, an oil pump 12, an oil temporary storage tank 13, and a nozzle 14. The oil storage tank 11, the oil pump 12, the oil temporary storage tank 13, and the nozzle 14 are connected sequentially through an oil inlet pipeline (not shown in the figure).

[0034] The oil storage tank 11 is used to store liquid silicone oil.

[0035] The oil pump 12 is used to pump the liquid silicone oil in the oil storage tank 11 to the oil temporary storage tank 13. The silicone oil supply mechanism also includes a motor 15, which is connected to the oil pump 12 and drives the oil pump 12 to operate. By controlling the speed of the motor 15, the pressure of the liquid silicone oil entering the oil temporary storage tank 13 can be increased to form high-pressure silicone oil.

[0036] Oil storage tank 13 is used to temporarily store high-pressure liquid silicone oil.

[0037] Nozzle 14 is used to atomize high-pressure silicone oil and spray it into the main pipeline 4. Nozzle 14 has an oil inlet 141 and an oil outlet. The oil inlet 141 is connected to the oil storage tank 13 through the oil inlet pipeline, and the oil outlet is connected to the main pipeline 4.

[0038] The silicone oil supply mechanism also includes a control valve, which controls the oil output of nozzle 14 and can also close the oil inlet passage of the silicone oil supply mechanism, preventing atomized silicone oil from being sprayed out of the nozzle 14. The control valve can be integrated into the nozzle 14, such as a solenoid valve nozzle. Alternatively, the control valve and nozzle 14 can be separately installed on the oil inlet line between the oil storage tank 13 and nozzle 14.

[0039] The nozzle 14 also has a return port 142, which is connected to the oil reservoir 11 through a return pipeline (not shown in the figure).

[0040] The silicone oil supply mechanism also includes flow meters 16, which are respectively installed on the inlet and return lines between the oil reservoir 11 and the oil pump 12. The flow meter 16 on the inlet line can detect the flow rate of silicone oil entering the nozzle 14, and the flow meter 16 on the return line can detect the flow rate of silicone oil flowing back to the oil reservoir 11. The difference between the two can be used to measure the flow rate of silicone oil used for cleaning the spinneret.

[0041] The pellet supply mechanism and the compressed gas supply mechanism are used to transport the pellet medium to the main pipeline 4 under the push of compressed gas. The pellet supply mechanism has an air inlet channel for compressed gas to enter the pellet supply mechanism and a discharge channel for pellets and compressed gas to flow out of the pellet supply mechanism together. The compressed gas supply mechanism is connected to the air inlet channel through the air inlet pipeline 3 (only part is shown), and the discharge channel is connected to the main pipeline 4.

[0042] Specifically, the pellet supply mechanism includes a hopper assembly, a feeding assembly, and a base.

[0043] like Figures 3-8 As shown, the hopper assembly has a storage chamber for storing particulate media. In this embodiment, the hopper assembly includes an upper hopper 211 located at the top and a lower hopper 212 located at the bottom. The lower hopper 212 is provided with a particle channel 2321 for the particulate media to flow out of the hopper assembly.

[0044] The feeding assembly is disposed on the hopper assembly and divides the storage chamber into an upper cavity 2111 and a lower cavity 2121 that are isolated from each other. In this embodiment, the feeding assembly is disposed between the upper hopper 211 and the lower hopper 212, the upper cavity 2111 is formed on the upper hopper 211, and the lower cavity 2121 is formed on the lower hopper 212.

[0045] The feeding assembly is located above the particle channel 2321, and has a feeding channel for the particle medium to flow through. The feeding assembly has a feeding state and a non-feeding state. When the feeding assembly is in the feeding state, the feeding channel is unobstructed, and the particle medium flows from the upper cavity 2111 into the lower cavity 2121 through the feeding channel, and then flows out of the hopper assembly through the particle channel 2321. When the feeding assembly is in the non-feeding state, the feeding channel is blocked, and the particle medium is stored in the upper cavity 2111.

[0046] like Figure 6 and Figure 8 As shown, in this embodiment, the feeding assembly includes a first feeding plate 221, a second feeding plate 222, and a distributing disc 223. The second feeding plate 222 is disposed below the first feeding plate 221, and the distributing disc 223 is disposed between the first feeding plate 221 and the second feeding plate 222, and is rotatably disposed relative to the first feeding plate 221 and the second feeding plate 222. In this embodiment, the second feeding plate 222 is provided with a groove that is concave downward from its upper end, and the distributing disc 223 is rotatably disposed in the groove. The upper cavity 2111 is formed above the first feeding plate 221, and the lower cavity 2121 is formed below the second feeding plate 222. When the distributing disc 223 rotates, the feeding channel is unobstructed; when the distributing disc 223 does not rotate, the feeding channel is blocked.

[0047] Specifically, such as Figure 4 , Figure 6 and Figure 8As shown, the first feeding plate 221 is provided with a first feeding port 2211 that penetrates its upper and lower end faces, the second feeding plate 222 is provided with a second feeding port 2221 that penetrates its upper and lower end faces, and the distributing plate 223 is provided with a distributing port 2231 that penetrates its upper and lower end faces. The first feeding port 2211, the distributing port 2231, and the second feeding port 2221 are arranged sequentially from top to bottom to form a feeding channel. The position of the first feeding port 2211 is staggered from the position of the second feeding port 2221. The size of the first feeding port 2211 and the second feeding port 2221 is larger than the size of the distributing port 2231. The distributing plate 223 can rotate to make the position of the distributing port 2231 correspond to the position of the first feeding port 2211 or the second feeding port 2221.

[0048] When the feeding assembly is in the feeding state, the distributing disc 223 first rotates until the distributing port 2231 corresponds to the position of the first feeding port 2211. The particulate medium in the upper cavity 2111 then flows from the first feeding port 2211 into the distributing port 2231. At this time, the position of the distributing port 2231 is offset from the position of the second feeding port 2221. When the distributing disc 223 continues to rotate until the position of the distributing port 2231 corresponds to the position of the second feeding port 2221, the particulate medium in the distributing port 2231 flows into the lower cavity 2121 through the second feeding port 2221.

[0049] When the feeding component is in a non-feeding state, the feeding tray 223 does not rotate. The feeding tray 223 can only correspond to the position of one of the first feeding port 2211 and the second feeding port 2221 at most. In this way, the feeding channel is always blocked and feeding cannot be achieved.

[0050] This feeding method of the feeding component ensures that the particulate medium does not flow out of the feeding channel at all when feeding is not required, thus making the feeding process more controllable.

[0051] Along the circumferential direction of rotation of the distribution disc 223, at least one first discharge port 2211 and one second discharge port 2221 are provided, and multiple distribution ports 2231 are provided. In this embodiment, two first discharge ports 2211 and two second discharge ports 2221 are provided, and multiple distribution ports 2231 are evenly distributed along the circumferential direction of rotation of the distribution disc 223. This configuration allows for continuous feeding when one feed port 2231 aligns with the first feed port 2211, enabling material to flow from the first feed port 2211 to the feed port 2231. When that feed port 2231 rotates to align with the second feed port 2221, enabling material to flow from the first feed port 2211 to the feed port 2221, the other feed port 2231 can rotate again to align with the first feed port 2211, thus feeding material from the first feed port 2211 to the feed port 2231. This cycle ensures continuous feeding and improves material supply efficiency.

[0052] The feeding assembly also includes a drive mechanism 224, which drives the dispensing disk 223 to rotate. In this embodiment, the drive mechanism 224 has a rotatable output shaft 2241, and the dispensing disk 223 is fixedly connected to the output shaft 2241. When the drive mechanism 224 is activated, causing the output shaft 2241 to rotate, it drives the dispensing disk 223 to rotate synchronously. In this embodiment, the drive mechanism 224 includes a drive motor.

[0053] By controlling the speed of the drive motor, the amount of granular media fed can be controlled.

[0054] The first feeding plate 221 has a tapered structure at one end facing the upper cavity 2111, which is wider at the top and narrower at the bottom. The first feeding port 2211 is located near the narrow end of the tapered structure. This makes it easier for the particulate media in the upper cavity 2111 to fall into the first feeding port 2211 under its own gravity, guided by the tapered structure.

[0055] The pellet supply mechanism also includes a guide member 23 disposed in the lower cavity 2121. The guide member 23 is located below the feeding assembly, and a pellet channel 2321 is formed on the guide member 23. The guide member 23 is used to guide the pellet medium falling into the lower cavity 2121, so that the pellet medium flows out of the hopper assembly from the pellet channel 2321.

[0056] Specifically, such as Figure 4 , Figure 6 and Figure 8 As shown, the guide member 23 includes a disc 231 located at the upper part and a first column 232 disposed at the lower part of the disc 231. The disc 231 has a conical structure that is larger at the top and smaller at the bottom. The first column 232 is sequentially connected to the small end of the disc 231, and a particle channel 2321 is formed on the first column 232. In this embodiment, the particle channel 2321 is the central hole of the first column 232.

[0057] After the particulate medium falls from the second discharge port 2221, it falls onto the disc 231. The conical structure of the disc 231 can play a good guiding role, making it easier for the particulate medium to fall into the particulate channel 2321 under its own gravity.

[0058] like Figure 6 As shown, the base 24 is fixedly connected to the hopper assembly. In this embodiment, the base 24 is fixedly connected to the lower part of the hopper 212. Both the air inlet channel 241 and the discharge channel are formed on the base 24. There is a gap between the inlet of the discharge channel and the outlet of the particle channel 2321. Compressed gas entering from the air inlet channel 241 can flow into the gap between the inlet of the discharge channel and the outlet of the particle channel 2321, thereby forming a negative pressure.

[0059] The discharge channel includes a central channel 2421 located at the center of the base 24 and a side channel 2422 connected to the central channel 2421 at one end. The central channel 2421 is located directly below the particle channel 2321. The size of the central channel 2421 is not smaller than the size of the particle channel 2321. Preferably, the central axis of the central channel 2421 and the particle channel 2321 are collinear, so that the particle medium flowing out of the particle channel 2321 enters the central channel 2421 as much as possible under the action of negative pressure.

[0060] In this embodiment, a second column 242 is provided at the center of the base 24, and the central channel 2421 is the central hole of the second column 242.

[0061] The guide component 23 is fixedly installed inside the lower cavity 2121 via the connector 25. For example... Figure 4 , Figure 6 and Figure 8 As shown, the connector 25 includes a first connecting part 251 located at the upper part and a second connecting part 252 located at the lower part. The first connecting part 251 is sleeved on the outside of the first column 232 and fixed to the first column 232. The second connecting part 252 is sleeved on the outside of the second column 242 and fixed to the second column 242.

[0062] like Figure 6 As shown, the base 24 also includes an air intake chamber 243 connected to the air intake channel 241, and the lower part of the hopper 212 is completely open. The pellet supply mechanism also includes a cyclone separator 26 disposed in the air intake chamber 243. The inlet of the cyclone separator 26 is connected to the air intake chamber 243, and the outlet of the cyclone separator 26 is connected to the lower cavity 2121. The cyclone separator 26 can adopt a structure found in the prior art, and its specific structure will not be described in detail. Compressed gas flows into the air intake chamber 243 through the air intake channel 241 and enters the cyclone separator 26. After flowing out of the cyclone separator 26, it forms a spiral airflow that enters the lower cavity 2121.

[0063] In this embodiment, such as Figure 6 As shown, the lower part of the second connecting part 252 is pressed onto the cyclone separator 26, thereby pressing the cyclone separator 26 between the second connecting part 252 and the base 24, thus fixing the cyclone separator 26.

[0064] like Figure 4 , Figure 6 and Figure 8 As shown, there is a hollow area between the first connecting part 251 and the second connecting part 252, so that the airflow in the lower cavity 2121 can flow from the hollow area to the gap area between the inlet of the discharge channel and the outlet of the particle channel 2321.

[0065] In this embodiment, to simplify the structure of the entire pellet supply mechanism, no sealing design is made between the hopper assembly, the guide 23 and the discharge hopper 212. In this way, the airflow entering the lower cavity 2121 will spiral up along the side wall of the hopper assembly until it fills the upper cavity 2111 and the lower cavity 2121 above the disc 231, and forms positive pressure in these areas. Thus, when the compressed gas enters the lower cavity 2121 again through the cyclone separator 26, the compressed gas flows from the hollow area between the first connecting part 251 and the second connecting part 252 to the gap area between the inlet of the discharge channel and the outlet of the pellet channel 2321, thereby forming negative pressure.

[0066] like Figure 3 ,like Figures 5-8 As shown, the pellet supply mechanism also includes a hopper 27, which has a conical structure that is larger at the top and smaller at the bottom. The hopper 27 is connected to the hopper assembly through a pipe, and a control valve 28 is installed on the pipe to control the opening or closing of the pipe.

[0067] The particle supply mechanism also includes a sensor 29, which is mounted on the hopper assembly and has its sensing end extending into the upper cavity 2111. The sensor 29 is used to monitor the height of the particle medium in the upper cavity 2111.

[0068] When the height of the particulate medium in the upper cavity 2111 is lower than the set height, the control valve 28 opens the pipeline, allowing the particulate medium to flow into the upper cavity 2111 through the hopper 27. When the height of the particulate medium in the upper cavity 2111 is not lower than the set height, the control valve 28 closes the pipeline, preventing the particulate medium in the hopper 27 from flowing into the upper cavity 2111.

[0069] like Figure 1 and Figure 2 As shown, the compressed gas supply mechanism includes a gas source device (not shown in the figure). The gas source device is connected to the air intake channel 241 through the air intake pipeline 31. A control valve 32 is provided on the air intake pipeline 31. The flow rate of the compressed gas entering the air intake channel 241 can be controlled by the control valve 32.

[0070] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
