Description
Technical Field
[0001] The utility model relates to the technical field of ring spinning machines, and particularly relates to a self-cleaning cotton suction air box device for a ring spinning machine. Background Art
[0002] As is well known, for the yarn breakage cotton suction device of the existing ring spinning machine and the negative pressure suction air device in the compact spinning draft mechanism installed thereon, negative pressure and air flow are generated by the suction air blower installed in the cotton suction air box, and then connected to the suction port through the air duct. A filter screen is installed in the cotton suction air box to block the fibers carried by the wind in the air duct. In the prior art, the fibers on the filter screen in the cotton suction air box can only be manually cleaned by workers when the ring spinning machine stops for doffing at the end of a spinning cycle. Therefore, the prior art has the following two deficiencies: First, in a spinning cycle, the amount of fibers on the filter screen is small at the initial stage of spinning, which will not affect the air flow and negative pressure in the air duct, and the spinning quality is good and stable. However, as spinning progresses, the amount of fibers on the filter screen will accumulate more and more in the later stage of spinning, reducing the ventilation area of the filter screen and the ventilation effect, inevitably leading to a decrease in the air flow and negative pressure in the air duct, thereby reducing the spinning quality and causing fluctuations in the spinning quality of the ring spinning machine. In the prior art, in order to prevent the reduction of spinning quality in the later stage of spinning, a frequency converter is also used to increase the frequency of the suction air blower, making the suction air blower run at an overclocked high speed, but this will be self-defeating. This will greatly increase the energy consumption of the suction air blower, increase the failure rate of the suction air blower, and cannot completely solve the problem of the reduction of spinning quality. Second, the manual cleaning by workers is not timely and thorough. Because it can only be cleaned when stopping for doffing, and there are many machines to be cleaned, there will be problems of being too late to clean and not cleaning cleanly, thus affecting the spinning quality. Moreover, the manual cleaning by workers is time-consuming and laborious, with a large working intensity and low working efficiency. Summary of the Invention

It can rotate and self-clean the filter screen, clean in a timely and clean manner, ensure the ventilation area and ventilation effect of the filter screen, ensure the suction air volume and negative pressure, and ensure the spinning quality.

[0014] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a self-cleaning cotton-sucking air box device for a ring spinning frame includes an air box body 1, a filter screen body 2, a driving wheel 3 and a suction fan 4. The air box body 1 is a cuboid member formed by connecting angle steel and steel plates. A hollow cavity 11 is provided inside the air box body 1. A waste cotton box 12 is provided below the inside of the air box body 1. An air box cotton-sucking port 13 is provided on the front side of the air box body 1, and an air box air outlet 14 is provided on the rear side. The air box cotton-sucking port 13 and the air box air outlet 14 are communicated with the hollow cavity 11. Waste cotton holes 15 are provided on the upper side of the waste cotton box 12. Guard plates 16 are provided on both sides of the waste cotton holes 15. A cotton-picking hole is provided on the side of the waste cotton box 12, and a sealing door plate is provided on the cotton-picking hole.
[0015] The filter screen body 2 includes a roller 21 and a cotton-sucking filter screen 22. A plurality of air inlet filter holes 23 are uniformly provided on the cylindrical surface of the roller 21. The cotton-sucking filter screen 22 is provided on the cylindrical surface of the roller 21. Two rolling cylinders 24 are provided inside the roller 21. The two rolling cylinders 24 are in contact with the inner wall of the roller 21 to form a triangular cavity 25. The filter screen body 2 is installed in the hollow cavity 11. A rotating shaft 26 is installed on the front end surface of the roller 21, and a roller air outlet 27 is provided on the rear end surface. Bearings are installed on the rotating shaft 26. The rotating shaft 26 is rotationally connected to the front side of the air box body 1 through the bearings. The roller air outlet 27 is communicated with the air box air outlet 14. Three support wheels 28 are uniformly provided on the inner edge of the roller air outlet 27. Bearings are installed inside the support wheels 28. The support wheels 28 are rotationally connected to a fixed connecting plate 29 through the bearings. The fixed connecting plate 29 is fixedly connected to the rear side of the air box body 1. The rear end of the roller 21 is rotationally connected to the rear side of the air box body 1 through the three support wheels 28. The lower half of the filter screen body 2 is inserted into the waste cotton holes 15. A sealing ring is provided between the rear end surface of the roller 21 and the rear side of the air box body 1.
[0016] The driving wheel 3 is arranged on the outside of the filter body 2. The driving wheel 3 is a rubber-coated wheel with rubber coated on its outer circle. The driving wheel 3 is in close contact with the cylindrical surface of the drum 21. The driving wheel 3 is installed on the output shaft of the driving motor 31. The driving motor 31 is fixedly installed on the rear side of the bellows body 1. The suction fan 4 is arranged on the outside of the bellows body 1 and is fixedly connected to the rear side of the bellows body 1. The air inlet of the suction fan 4 is connected to the bellows outlet 14.
[0017] The suction fan 4 is a machine that generates gas pressure and delivers gas by inputting mechanical energy. When the suction fan 4 is in operation, a certain negative pressure and flowing airflow will be generated in the hollow cavity 11. The airflow flows in from the cotton suction port 13 of the bellows, passes through the hollow cavity 11 and the filter body 2, and flows out from the air outlet 14 of the bellows. With the flow of airflow and the effect of negative pressure, a large amount of cotton fibers will be adsorbed on the cotton suction filter 22 of the filter body 2. The two rolling cylinders 24 are in contact with the inner wall of the drum 21 to form a triangular cavity 25. The outer cylindrical surfaces of the two rolling cylinders 24 are in contact with the inner wall of the drum 21, and the two end surfaces of the two rolling cylinders 24 are in contact with the front and rear end surfaces of the drum 21. The triangular cavity 25 is a closed inner cavity, and no negative pressure and flowing airflow are generated in the triangular cavity 25.
[0018] The driving motor 31 rotates the driving wheel 3 and drives the filter body 2 to rotate slowly. When the filter body 2 rotates slowly, the two rolling cylinders 24 rotate at the bottom of the drum 21 under the action of their own gravity. The triangular cavity 25 is always located at the bottom of the drum 21. When the filter body 2 rotates slowly and drives the cotton fibers to rotate outside the triangular cavity 25, the cotton fibers are no longer affected by the airflow and negative pressure. Under the action of their own gravity, the cotton fibers break away from the cotton suction filter 22 and fall into the return flower box 12 through the return flower hole 15. The filter body 2 realizes rotation self-cleaning. The textile workers can open the sealing door panel at any time to clean the cotton fibers that fall into the return flower box 12 from the hollowing hole.
[0019] Without limitation to this, any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope defined in the claims.
