Description

Technical Field

[0001] This utility model relates to the field of film blowing machine cooling technology, and in particular to an improved air-cooling component for film blowing machines. Background Technology

[0002] A blown film machine is a plastic processing machine. Plastic is melted and extruded in a screw extruder in a measured quantity. It is then formed through a die, cooled by an air ring, and then pulled by a traction machine at a certain speed. Finally, a winding machine winds it into a roll.

[0003] During the operation of the blown film machine, the air-cooling component delivers cold air to the surface of the blown film, quickly removing the heat from the film and facilitating rapid cooling and shaping, thereby improving the quality of the film and production efficiency.

[0004] When the cold air blown out by the air-cooling component flows inside the gas transmission pipe, the temperature difference between the inside and outside of the pipe, coupled with the high humidity in the air, causes the cold air temperature to be lower than the surrounding environment. This makes it easy for water vapor to condense into water droplets on the inner wall of the pipe. These droplets are then blown out with the cold air and adhere to the membrane surface, affecting the membrane's quality, such as causing water stains or streaks. Furthermore, the long-term accumulation of water droplets may corrode the inner wall of the gas transmission pipe, shortening its lifespan and increasing equipment maintenance costs.

[0005] Therefore, it is necessary to provide an improved air-cooling assembly for blown film machines to solve the above-mentioned technical problems. Utility Model Content

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 ,in, Figure 1 A schematic diagram of a preferred embodiment of the improved blown film machine air-cooling assembly provided by this utility model; Figure 2 for Figure 1 The diagram shows a partial sectional view of the structure. Figure 3 for Figure 2 The diagram shows an exploded view of the internal structure. Figure 4 for Figure 3 The diagram shows an enlarged view of the local structure. Figure 5 for Figure 1 The side sectional view shown is shown below; Figure 6 for Figure 5 The enlarged schematic diagram of part A is shown. The improved blown film machine air-cooling assembly includes: a blown film body 1, an mounting plate 11 on the outside of the blown film body 1, a support member 2 on the top of the mounting plate 11, a driving member 3 on the outside of the mounting plate 11 for moving the support member 2, an air supply member 4 on the outside of the support member 2, a positioning member 5 inside the air supply member 4, a rotating member 6 inside the positioning member 5, and a scraping assembly 7 on the outside of the rotating member 6. The scraping assembly 7 includes a synchronization plate 71, two support plates 72, two silicone blocks 73, two rotating blocks 74, and a fixing ring 75. The synchronization plate 71 is fixedly connected to the rotating member 6, the two support plates 72 are fixedly connected to the synchronization plate 71, the two silicone blocks 73 are fixedly connected to the two support plates 72, the two rotating blocks 74 are fixedly connected to the two support plates 72, the fixing ring 75 is connected to the air supply member 4, and the two rotating blocks 74 are rotatably connected to the fixing ring 75.

[0033] The blown film body 1 enables film production. The mounting plate 11 provides a mounting base for each component. The drive component 3 enables the support component 2 to move, and the support component 2 provides support for the air supply component 4, so that the air blown out by the air supply component 4 cools the film on the blown film body 1. The positioning component 5 enables the rotating component 6 and the scraping component 7 to be installed inside the air supply component 4. When the air supply component 4 is started through the control panel, the rotating component 6 on the positioning component 5 is blown by the wind, so that the rotating component 6 can rotate automatically. When the rotating component 6 rotates, it can drive the synchronous plate 71 in the scraping component 7 to rotate, so that the support plate 72 rotates and drives the silicone block 73 to scrape the unformed water droplets on the inner wall of the internal pipe of the air supply component 4. The rotating block 74 is installed on the support plate 72 and is supported by the fixing ring 75 to prevent the support plate 72 from shaking and affecting the scraping effect of the silicone block 73 on the inside of the air supply component 4.

[0034] The support component 2 includes a long groove 21, a bracket 22 and two inclined blocks 23. The long groove 21 is opened on the top of the mounting plate 11. The bracket 22 is slidably connected to the long groove 21, and the two inclined blocks 23 are fixedly connected to the bracket 22.

[0035] The control panel enables the drive component 3 to move the bracket 22 on the long slot 21 when it is started, thereby blowing air to dissipate heat at different positions of the film. The two inclined blocks 23 increase the stability of the bracket 22.

[0036] The driving component 3 includes two fixing blocks 31, a driving component 32, and a connecting block 33. The two fixing blocks 31 are fixedly connected to the mounting plate 11, the driving component 32 is rotatably connected to the two fixing blocks 31, the connecting block 33 is connected to the driving component 32, and the connecting block 33 is fixedly connected to the bracket 22.

[0037] When the drive component 32 rotates, the connecting block 33 moves, causing the bracket 22 to move, thereby allowing the bracket 22 to slide on the long groove 21. The drive component 32 consists of a lead screw and a motor. The lead screw rotates with the fixed block 31, and the motor is fixedly connected to the lead screw. When the motor rotates, it causes the lead screw to rotate, thereby moving the connecting block 33 fixed on the bracket 22.

[0038] The air supply component 4 includes a blower 41, an air pump 42, an air supply pipe 43, and an air blowing plate 44. The blower 41 is fixedly connected to the bracket 22, the air pump 42 is fixedly connected to the blower 41, the air supply pipe 43 is fixedly connected to the bracket 22, the air blowing plate 44 is fixedly connected to the air supply pipe 43, and the silicone block 73 is slidably connected to the air supply pipe 43.

[0039] Gas generated by blower 41 is pressurized by air pump 42 and absorbed by air pump 42 through the suction pipe and discharged into air delivery pipe 43 through exhaust pipe. When the gas enters the air delivery pipe 43, it drives the rotating component 6 to rotate. When the rotating component 6 rotates, the silicone block 73 in the scraping component 7 cleans the moisture adhering to the inside of the air delivery pipe 43, preventing it from condensing into large water droplets and being blown out with the wind.

[0040] The positioning component 5 includes three positioning blocks 51 and a positioning tube 52. The three positioning blocks 51 are fixedly connected to the gas supply pipe 43, and the positioning tube 52 is fixedly connected to the three positioning blocks 51.

[0041] The positioning block 51 is fixed to the inner wall of the gas pipeline 43 to provide an installation base for the positioning tube 52, thereby providing rotational support for the rotating component 6.

[0042] The rotating component 6 includes a rotating rod 61 and a fan blade 62. The rotating rod 61 is rotatably connected to the positioning tube 52, and the fan blade 62 is fixedly connected to the rotating rod 61.

[0043] When the air inside the gas pipe 43 blows, it drives the fan blade 62 to rotate. When the fan blade 62 rotates, it is supported on the positioning pipe 52 by the rotating rod 61. A limit ring and a limiting block are installed on the rotating rod 61. The limit ring and the limiting block are installed on the outside of the rotating rod 61. The axial movement of the rotating rod 61 can be prevented by the cooperation of the limit ring and the limiting block.

[0044] The gas supply pipe 43 is provided with a drain component 8 on its exterior. The drain component 8 includes a collection trough 81, a drain pipe 82, and a collection box 83. The collection trough 81 is opened on the inner wall of the gas supply pipe 43. The drain pipe 82 is fixedly connected to the gas supply pipe 43. The collection box 83 is fixedly connected to the support 22.

[0045] The water vapor adhering to the inner wall of the gas delivery pipe 43 is pushed into the collection tank 81 by the silicone block 73, and then falls into the collection box 83 through the drain pipe 82 due to gravity.

[0046] The working principle of the improved blown film machine air-cooling component provided by this utility model is as follows:

[0047] First, the blown film body 1 starts to produce film. The mounting plate 11 provides the mounting base for each component. At the same time, the drive component 3 moves the support component 2, which in turn supports the air supply component 4, allowing the air supply component 4 to move to different positions to cool the film on the blown film body 1. Then, the air supply component 4 is started via the control panel. The air drives the rotating component 6 on the positioning component 5 to rotate. The rotating component 6 drives the synchronous plate 71 in the scraping assembly 7 to rotate, which in turn causes the support plate 72 to drive the silicone block 73 to rotate. Finally, the rotating silicone block 73 scrapes away the water droplets that have not condensed on the inner wall of the internal pipe of the air supply component 4. The rotating block 74 is mounted on the support plate 72 and is supported by the fixing ring 75 to prevent the support plate 72 from shaking and to ensure the scraping effect of the silicone block 73.

[0048] Compared with related technologies, the improved blown film machine air-cooling component provided by this utility model has the following beneficial effects:

[0049] The coordinated operation of the support component 2, drive component 3, air supply component 4, positioning component 5, rotating component 6, and scraping component 7 prevents water droplets from forming on the inner wall of the air supply pipe 43 and being blown out with the cold air, thus adhering to the membrane surface. This effectively ensures the quality of the membrane, preventing water stains, blemishes, and other defects on the membrane surface, ensuring a good appearance and quality. Simultaneously, it prevents corrosion of the inner wall of the air supply pipe 43 caused by long-term moisture accumulation, extending the service life of the air supply pipe 43. It also reduces downtime caused by frequent replacements of the air supply pipe 43 due to damage, ensuring production continuity and lowering equipment maintenance costs.
