[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 , Figure 2, an embodiment provided by the present utility model: a bubble stabilizing device for a blown film machine, comprising a plurality of connecting plates 1. A driving assembly for providing a telescopic force is fixedly connected to the top of the connecting plate 1. The driving assembly includes a hydraulic cylinder 3, which is made of high-strength steel and can maintain stability during high-speed movement. The driving end of the hydraulic cylinder 3 is fixedly connected to a first telescopic column 4, which is made of wear-resistant material and can maintain stability during high-speed movement. A fixed block 5 is fixedly connected to the outside of the first telescopic column 4, which is made of wear-resistant material to ensure stability and long service life during frequent movement. A first circular ring plate 2 is rotatably connected to the top of the connecting plate 1, which is made of high-strength steel and can maintain stability during high-speed movement. A plurality of connecting blocks 6 are fixedly connected to the top of the first circular ring plate 2, which are made of wear-resistant material and can maintain a good fixing effect during long-term use. A second circular ring plate 7 is fixedly connected to the top of the plurality of connecting blocks 6, which is made of high-strength steel and can maintain stability during high-speed movement. A bearing column 8 is fixedly connected to the top of the connecting plate 1, which is made of wear-resistant material and can maintain stability during long-term use. A force-applying column 9 is slidably connected to the inside of the bearing column 8. A connecting bar 10 is rotatably connected to the outside of the force-applying column 9. A slider 11 is slidably connected to the outside of the connecting bar 10. A second telescopic column 12 is fixedly connected to the top of the slider 11. A limiting plate 13 is fixedly connected to the inside of the connecting bar 10. The limiting plate 13 ensures that each part of the device will not move beyond the limit during operation, thus ensuring mechanical safety. The outside of the second telescopic column 12 is slidably connected to the inside of the second circular ring plate 7. The second telescopic column 12 moves freely in a plane, enabling the entire device to better adapt to the dynamic changes during the blowing process. A plurality of support columns 24 are fixedly connected to the adjacent sides of the two connecting plates 1. The support columns 24 strengthen the overall structural stability, ensuring that the machine maintains high precision and high efficiency during long-term operation.

[0032] Refer to Figure 1 , Figure 3 , Figure 4The outer part of the bearing column 8 is fixedly connected with a limit ring 14, and the limit ring 14 is made of wear-resistant material, such as carbide or high-quality plastic, and its shape is designed to accurately match the outer diameter of the bearing column 8 to ensure that it maintains a stable position during movement. The outer sliding connection of the limit ring 14 is a protective ring 16, and the protective ring 16 is made of a lightweight but strong material, such as a carbon fiber composite material, and its inner surface is smooth to reduce the friction with the limit ring 14, thereby allowing smooth relative movement. The inner sliding connection of the bearing column 8 is a plurality of balls 17, and the balls 17 are made of hard steel or ceramic materials to ensure extremely high wear resistance and precision during the rolling process inside the bearing column 8. The outer sleeve of the bearing column 8 is provided with a spring 15, and the spring 15 is made of a highly elastic material, so that the spring 15 can provide stable resistance when the bearing column 8 moves, while maintaining the stability of the overall structure. Qualitatively, the bearing column 8 is internally fixedly connected to a limiting column 21, the limiting column 21 is fixedly connected to a spring 3 22, the spring 3 22 is fixedly connected to a fixed column 23, the limiting column 21 and the fixed column 23 are both made of high-strength materials to ensure that they will not move or deform easily when subjected to a large force, the force-applying column 9 is internally fixedly connected to a limiting column 18, the limiting column 18 is externally fixedly connected to a spring 2 19, the combination of the limiting column 18 and the spring 2 19 is intended to provide stable support for the force-applying column 9 while allowing a certain degree of adjustment and movement when necessary, the spring 2 19 is externally fixedly connected to a fixed column 20, the fixed column 20 is also made of high-pressure resistant and corrosion-resistant materials to adapt to various complex working environments, one end of the spring 15 is fixedly connected to the outside of the limiting ring 14, and the other end of the spring 15 is fixedly connected to the inside of the protective ring 16.

[0033] Compared with some devices in the prior art, the above content, by pushing the circular ring plate 2 to move left and right through the telescopic column 4, the slider 11 on the circular ring plate 2 moves with the circular ring plate 2, so that the connecting strip 10 inside the slider 11 slides, thereby changing the positions of multiple limit plates 13, and by moving the protective ring 16 to disengage it from the limit ring 14, the ball 17 is separated from the fixed column 20, so that the fixed column 23 drives the force column 9 to disengage from the load-bearing column, which solves the problem that some devices cannot adapt to membranes of different sizes and cannot disassemble and repair parts of the overall device.

[0034] Working principle: First, start the hydraulic cylinder 3 to make multiple telescopic columns 4 telescopic, so that the fixed block 5 in the slot of the telescopic column 4 moves accordingly, so that the circular plate 2 fixed with the fixed block 5 moves left and right on the connecting plate 1, so that the slider 11 fixed on the circular plate 2 moves accordingly, and at the same time, there is a connecting strip 10 on the slider 11 in the internal hole of the circular plate 27, and there is a connecting strip 10 in the middle of the slider 11, so that the connecting strip 10 slides inside the slider 11, so that the connecting strip 10 rotates on the force column 9, changing the angle of the slider 11, and then the limit plate 13 at the tail of the slider 11 also moves, so that the size of the foam maintained by the foam stabilizing device is changed, and it can flexibly respond to customer needs or market changes.

[0035] When a single connecting strip 10 and the structure connected to it are damaged and need repair, the protective ring 16 is moved to squeeze the internal spring 15 to make it slide outside the supporting column 8 and disengage from the limit ring 14, so that the ball 17 loses its limit and is squeezed off from the fixed column 20, so that the fixed column 20 and the supporting column 8 lose connection, and then the limiting column 18 and the limiting column 21 are separated by the reaction force provided by the spring 2 19 and the spring 3 22 respectively, so that the fixed column 1 20 and the fixed column 2 23 are separated, and then the supporting column 8 and the force-applying column 9 are quickly separated, so that the problem can be repaired wherever it occurs, which reduces the production downtime and will not affect the efficiency and production plan of the production line.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
