Description

Technical Field

[0001] The utility model belongs to the technical field of carbon fiber production line unwinding equipment, and specifically relates to a humidifying device suitable for carbon fiber unwinding equipment. Background Art

[0002] The carbon fiber unwinding equipment is the source equipment of the production line. Whether it can provide continuous and well-formed raw yarn to the subsequent equipment is the key factor to determine the quality of the finished product and the premise for the smooth operation of the production line. In the unwinding equipment, after the raw yarn is unwinded, it passes through multiple guide rollers and small collection rollers. After the collection rollers, it is easy to generate static electricity. It is easy to entangle the rollers when passing through the subsequent collection rollers, and it is easy to cause the raw yarn to explode, causing the raw yarn bundles to cross-friction with each other. The more cross-fried, the easier it is to entangle the rollers. This vicious cycle greatly affects the quality of the raw yarn and the finished product, and may cause safety hazards such as fires in the carbon fiber production line, and even endanger personal safety. The current traditional unwinding equipment humidifies and removes static electricity by manually spraying water on the surface of the raw yarn through a kettle. The problem with this method is that as the production line increases, hundreds or thousands of raw yarn shafts are manually processed, the workload is extremely large, the number of personnel is large, and the labor cost is increased. In addition, it is easy to cause uneven water spraying and poor static elimination effect. At present, there is another way, which is to eliminate the static electricity of the yarn frame of the wire drawing machine through the static elimination system. The problem with this solution is that the static elimination system is expensive, the maintenance cost of the high-voltage electrode needle is high, and personnel may be easily injured if they accidentally touch the high-voltage electrode needle.

A drainage pipe 11 is connected between the drain ports 9 on the humidifying box body 4 of most of the carbon filament humidification components 2.

[0019] Principle of the utility model:

[0020] (1) Start the over-frequency oscillation humidifier 1, filter out suspended matter and impurities in the water through the ball valve 13 and the water purification filter 14, and then enter the over-frequency oscillation humidifier 1. The oscillation frequency of the humidifier is 1.7MHz, which is beyond the human hearing range and is harmless to humans and animals. Through the vibration of the atomizer, a natural and flowing water mist is generated, which does not require heating or chemicals to generate, and is safe and reliable. The humidifier also has a working status and alarm display function. There will be corresponding prompts for the operating status, water shortage, full water, etc., and personnel can operate and handle according to the actual situation.

[0021] (2) At the outlet of the humidifier, water mist is transported to multiple groups of elastic yarn humidification components through pipeline 3, and after passing through flow control valve 10, it enters the frame tube shell in the humidification box 4 to perform spray destaticization operation on the yarn bundle.

[0022] (3) After a long period of spraying, some excess water can fall into the humidification box 4 through the air holes 15 on the humidification tube shell 6, converge into the bottom of the humidification box 4, and then enter the drainage pipe 11 through the bottom drainage port 9 to be discharged as waste water.

[0023] (4) The humidification box body 4 and the humidification tube shell 6 are provided with carbon filament inlet and outlet 8 at the front and rear, which are the channels for the filament bundle to pass through the box body and be transported to the rear-end equipment; the humidification tube shell 6 is in an arc shape, which is convenient for the collection of water vapor; the humidification box body 4 can be opened in the form of a flip cover, which is convenient for personnel to clean the inside; a drainage port 9 is left at the bottom of the humidification box, which can facilitate the discharge of waste water from the box body.

[0024] (5) The height adjustment bracket 5 supports the humidification box 4. The bracket can be adjusted up and down to adapt to the wire paths of different heights and ensure that the wire bundle is not scratched during normal production. The bracket adopts a stable structure and is also easy to carry.

[0025] (6) On-site operators can set the required process humidity on the touch screen interface to perform controllable humidity adjustment. The specific principle is as follows: a humidity sensor 12 is installed on the inside of the humidifying box 4. If it is detected that the humidity inside the box is too low, the signal is transmitted back to the PLC control system. The processed signal is used to adjust the opening of the flow regulating valve 10 to increase the amount of water mist entering the humidifying box 4; if it is detected that the humidity inside the box is too high, the signal is transmitted back to the PLC control system. After adjustment by the closed-loop system, the opening of the flow regulating valve 10 is reduced, and the amount of water mist entering the humidifying box 4 is reduced. As the yarn bundle runs, part of the water mist is taken away, and the humidity in the box is reduced. Through the closed-loop control of the humidity sensor 12, the PLC system and the flow regulating valve 10, the humidity in the humidifying box 4 can be effectively adjusted, and static electricity is effectively eliminated while protecting the yarn bundle, thereby achieving the expected controllable humidification effect.

[0026] Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model should be considered to belong to the protection scope of the present utility model.
