Description

Technical Field

[0001] This invention relates to the field of thin film production technology, and specifically to an air ring device. Background Technology

[0002] The air ring device is a component of a blown film machine, installed at the film bubble discharge end of the die head. For example, utility model patent application number 202121876955.5 discloses a double-layer air ring and a blown film machine. The double-layer air ring includes: an upper air ring assembly with an annular air wall and multiple air inlets; a lower air ring assembly detachably connected to the upper air ring assembly to form a flow guiding chamber, with the air inlets connected to the flow guiding chamber, which has two flow channels, each with an air outlet connected to the film bubble channel; the lower air ring assembly has two annular guide vanes, with the air wall located between the two guide vanes; and multiple air nozzles, each corresponding to one of the air inlets. This double-layer air ring can achieve high-speed blowing when handling large-diameter membrane bubbles in actual use, but when handling small-diameter membrane bubbles, the inward air force is weak and the air speed is low, resulting in poor applicability, low production capacity, and a significant reduction in production efficiency. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a wind ring device with stronger applicability.

[0004] Therefore, the present invention is implemented using the following technical solution:

The first ring body and the upper cover are connected by threads, and the second ring body and the first ring body are connected by threads. A horn ring is connected to the second ring body by threads. The outer circumference of the upper cover is equally divided with multiple air inlets, and an air inlet channel is formed between the upper cover and the lower cover. A first air duct communicating with the air inlet channel is formed between the lower cover and the first ring body. A second air duct communicating with the air inlet channel is formed between the first ring body and the second ring body. The device is characterized in that: the inner end of the lower cover is provided with an upwardly protruding first air ring, the outer circumference of the first air ring has a first inclined surface that slopes outward from bottom to top, and the upper end of the first air ring is provided with a second inclined surface that slopes downward from inside to outside.

[0007] Furthermore, the lower cover of the air inlet channel is provided with a second air ring and a third air ring, and the upper cover of the air inlet channel is provided with a fourth air ring extending between the second air ring and the third air ring. The inner wall of the first ring is a flared opening with a diameter that gradually increases from bottom to top.

[0021] Referring to the above figures, the air ring device provided by the present invention includes an upper cover 1, a lower cover 2, a first ring body 3, and a second ring body 4. The first ring body 3 and the upper cover 1 are connected by threads, and the second ring body 4 and the first ring body 3 are connected by threads. A horn ring 5 is threaded onto the second ring body 4. The outer circumference of the upper cover 1 is equally divided with a plurality of air inlets 6, and an air inlet channel 7 is formed between the upper cover 1 and the lower cover 2. A first air duct 8 communicating with the air inlet channel 7 is formed between the lower cover 2 and the first ring body 3. A connection is formed between the first ring body 3 and the second ring body 4 communicating with the air inlet channel 7. The second air duct 9 is characterized in that: the inner end of the lower cover 2 is provided with an upwardly protruding first air ring 10, the outer ring of the first air ring 10 has a first inclined surface 11 that slopes outward from bottom to top, and the upper end of the first air ring 10 is provided with a second inclined surface 12 that slopes downward from inside to outside. The angle formed by the first inclined surface 11 and the upper end surface of the lower cover 2 is 65-75°, and the angle formed by the second inclined surface 12 and the inner wall of the first ring body 3 is 65-75°. The lower cover 2 in the air inlet channel 7 is provided with a second air ring 13 and a third air ring 14, and the upper cover 1 in the air inlet channel 7 is provided with a second air ring 13 extending into the second air ring 13. The fourth air ring 15 is located between the first ring body 3 and the third air ring 14. The inner wall of the first ring body 3 is a flared opening with a gradually increasing diameter from bottom to top. The lower cover 2 inside the first air duct 8 is provided with a fifth air ring 16. The lower outer end of the first ring body 3 can abut against the fifth air ring 16. The lower outer ring of the first ring body 3 is provided with a first through hole 17 connecting the air inlet channel 7 and the first air duct 8. The outer ring of the first ring body 3 is also provided with at least one second through hole 18 connecting the air inlet channel 7 and the second air duct 9. The bottom of the first ring body 3 is provided with a ring of compressed air groove 19, and the inner side of the bottom of the first ring body 3 is provided with a ring of compressed air. The boss 20, the air-compressing boss 20 and the first ring body 3 are transitioned by the third inclined surface 21. The lower cover 2 is provided with a sixth air ring 22 that extends into the air-compressing groove 19. The lower end of the air-compressing boss 20 has a rounded corner 23. The second air ring 13, the third air ring 14, the fifth air ring 16, the sixth air ring 22 and the lower cover 2 are all transitioned by the first arc surface 24. The fourth air ring 15 and the upper cover 1 are transitioned by the second arc surface 25. The upper end of the horn ring 5 is provided with an inwardly inclined bent part 26. The first ring body 3 and the second ring body 4 are both provided with an adjustment handle or an adjustment ring.

[0022] In this embodiment, the first inclined surface 11, the second inclined surface 12, and the first ring body 3 cooperate to allow the air coming out of the first air duct 8 to converge inward, maintaining a large air force and high air speed even when blowing small-diameter membrane bubbles. Moreover, the degree of fit between the first ring body 3 and the first inclined surface 11 and the second inclined surface 12 can be adjusted by rotating the first ring body 3, and the air output size of the second air duct 9 can be adjusted by rotating the second ring body 4. This is suitable for producing films of different diameters. By setting the above-mentioned inclined surface structure, the specific diameter air ring can process plastic films with even smaller diameters, making it more versatile, increasing production capacity, and improving work efficiency. In addition, the inner wall of the first ring body 3 is a funnel-shaped opening with the diameter gradually increasing from bottom to top, which facilitates the air to drag the film up, making the film output smoother and increasing production capacity. The second air ring 13, the third air ring 14, and the fourth air ring 15 allow the air entering from the air inlet 6 to enter the first air duct 8 and the second air duct 9 more evenly; the air compression groove 19 and the sixth air ring 22 work together to allow the air from the first through hole 17 to flow more evenly to the air compression boss 20, and after being compressed by the air compression boss 20, it is blown out at high speed from the outlet of the second air duct 9; the first arc surface 24, the second arc surface 25, the third shoe surface, and the rounded corner 23 make the air flow more smoothly inside the air ring, thus making the air force stronger; the bend 26 allows the air to converge inward when passing through the horn ring 5, concentrating the air force; the adjustment handle or adjustment ring allows the user to rotate the first ring body 3 or the second ring body 4 at any time without stopping the machine for adjustment, making the adjustment operation more convenient.

[0023] Usage method description: When processing films with a lower diameter, simply rotate the first ring body 3 counterclockwise to move the first ring body 3 upward relative to the upper cover 1 and the lower cover 2, thereby causing the air-pressing protrusion 20 to gradually approach the second inclined surface 12. At this time, more air is gathered inward through the second inclined surface to achieve the production of films with a lower diameter under the conditions of high wind force and high wind speed, resulting in higher production capacity.
