Description

Technical Field

[0001] This utility model belongs to the field of plastic processing technology, specifically a film bubble cooling device for blown film machines. Background Technology

[0002] A blown film machine is a type of machinery used to produce plastic films. It heats and melts plastic granules, then extrudes them into tubular film bubbles through an extruder. The bubbles are then cooled, drawn, and wound to form the final film. It is a core production equipment in the fields of plastic packaging, agricultural mulch film, and industrial films.

[0003] The film bubble must be cooled. The core purpose of the cooling is to quickly transform the high-temperature molten plastic into a stable solid film. This process directly determines the physical properties, processing efficiency, and finished product quality of the film.

[0004] Existing blown film machines typically lift the film bubble to a certain height after blowing, allowing it to cool naturally during the lifting process before winding it up. However, long-term use and observation have revealed that this cooling method results in a long cooling time and poor cooling effect. If the film bubble is not thoroughly cooled before winding it up, it can lead to adhesion and damage. Therefore, a film bubble cooling device for blown film machines is proposed to address these issues. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a film bubble cooling device for blown film machines.

[0006] The technical solution adopted by this utility model to solve its technical problem is a film bubble cooling device for a blown film machine, including an operating table. Multiple first support columns are fixedly connected to the operating table. First support plates are fixedly connected to the ends of the multiple first support columns. Multiple second support columns are fixedly connected to the first support plates. Second support plates are fixedly connected to the multiple second support columns. Through holes are opened on the second support plates and the first support plates. A pair of support frames are provided on the second support plates. A pair of guide rollers are rotatably connected between the pair of support frames. An auxiliary roller is provided on the second support plate. A winding machine is provided on the operating table. A connecting plate is provided on the second support plate. The connecting plate and the through holes are correspondingly arranged. An air storage box is fixedly connected to the first support plate. An air pump is connected to the air storage tank, and an air supply pipe is connected to the air pump. The other end of the air supply pipe is connected to a connecting plate, and multiple air outlet pipes are connected to the connecting plate. A blown film machine is installed on the operating table, and a raw material box is connected to the blown film machine. The raw material box and the operating table are fixedly connected. A connecting plate is installed on the second support plate, and the air storage tank is fixedly connected to the first support plate. The air supply pipe is connected to the air pump, and multiple air outlet pipes are connected to the connecting plate. During use, air from the air storage tank can be blown onto the surface of the film bubble through multiple air outlet pipes. This can cool the surface of the film bubble and reduce the possibility of incomplete cooling of the film bubble due to natural cooling during use, which could lead to overheating and damage to the film bubble during winding.

[0007] Preferably, multiple baffles are fixedly attached to the connecting plate. The baffles are arranged in an array and correspond to the air outlet pipe. By fixing multiple baffles to the connecting plate, the airflow ejected from the air outlet pipe can be dispersed during use. The dispersed air can better contact the surface of the membrane bubble, thereby achieving a better cooling effect.

[0008] Preferably, a connecting rod is fixedly connected to the baffle plate, and a connecting block is rotatably connected to the end of the connecting rod. Multiple baffles are fixedly connected to the connecting block. By rotatably connecting the connecting block to the end of the connecting rod and fixing multiple baffles to the connecting block, the baffles can rotate when the air moves along the direction of the baffle plate to a designated position during use, further disturbing the air and thus achieving a better cooling effect.

[0009] Preferably, the baffle plate has multiple air outlets arranged in an array. By having multiple air outlets on the baffle plate, the air velocity can be increased during use, thereby enhancing the cooling effect of the air on the membrane bubble.

[0010] Preferably, a water tank is fixedly connected to the first support plate, a water pump is connected to the water tank, and a water supply pipe is connected to the water pump. Multiple connecting columns are fixedly connected to the connecting plate, and a sprinkler plate is fixedly connected to the connecting columns. The water supply pipe and the sprinkler plate are connected. By fixing the sprinkler plate to the connecting column, connecting the water supply pipe to the sprinkler plate, connecting the water pump to the end of the water supply pipe, and connecting the water tank to the water pump, water from inside the water tank can be sprayed onto the surface of the membrane bubble through the sprinkler plate during use, thereby cooling the membrane bubble.

[0011] Preferably, a sponge block is fixedly attached to the sprinkler plate, and the sponge block is located between the first support plate and the sprinkler plate. By fixing the sponge block to the sprinkler plate, the water that has not evaporated from the surface of the membrane bubble can be collected during use, reducing the possibility of water falling onto the surface of the first support plate and causing pollution to the first support plate.

[0012] The advantages of this utility model are:

[0013] This utility model provides a film bubble cooling device for a blown film machine. It has a connecting plate on the second support plate, an air storage box fixedly connected to the first support plate, an air supply pipe connected to the air pump, and multiple air outlet pipes connected to the connecting plate. During use, the air in the air storage box can be blown to the surface of the film bubble through the multiple air outlet pipes, which can cool the surface of the film bubble and reduce the situation where the film bubble is not thoroughly cooled by natural cooling during use, which may cause the film bubble to be damaged due to overheating during the film bubble winding process.

[0014] This utility model provides a film bubble cooling device for a blown film machine. By fixing multiple baffles to the connecting plate, the airflow ejected from the air outlet can be dispersed during use. The dispersed air can better contact the surface of the film bubble, thus achieving a better cooling effect. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1-5As shown, a film bubble cooling device for a blown film machine includes an operating table 1. Multiple first support columns 11 are fixedly connected to the operating table 1. First support plates 12 are fixedly connected to the ends of the multiple first support columns 11. Multiple second support columns 13 are fixedly connected to the first support plates 12. Second support plates 14 are fixedly connected to the multiple second support columns 13. Through holes 15 are formed on the second support plates 14 and the first support plates 12. A pair of support frames 16 are provided on the second support plates 14. A pair of guide rollers 17 are rotatably connected between the pair of support frames 16. An auxiliary roller 18 is provided on the second support plates 14. A winding machine 19 is provided on the operating table 1. A connecting plate 110 is provided on the second support plates 14. Plate 110 and through hole 15 are correspondingly arranged. An air storage box 111 is fixedly connected to the first support plate 12. An air pump 112 is connected to the air storage box 111. An air supply pipe 113 is connected to the air pump 112. The other end of the air supply pipe 113 is connected to the connecting plate 110. Multiple air outlet pipes 114 are connected to the connecting plate 110. A blown film machine 115 is set on the operating table 1. A raw material box 116 is connected to the blown film machine 115. The raw material box 116 is fixedly connected to the operating table 1. During operation, the blown film machine 115 (model SL65-1000) and the raw material box 116 are controlled by the control box 7 set on the first support column 11. When the raw material box 116 is opened, the raw material in the raw material box 116 is released. The material is fed into the blown film machine 115. After processing, the blown film machine 115 blows the material into a film bubble. Once the film bubble is formed, it passes through the through hole 15 and the inside of the connecting plate 110. When the film bubble passes through the connecting plate 110, the air pump 112 is activated through the control box 7. When the air pump 112 is activated, the air inside the air storage tank 111 is sent into the connecting plate 110 through the air supply pipe 113. When the air enters the connecting plate 110, it is ejected from the multiple air outlet pipes 114 connected to the connecting plate 110. The ejected airflow comes into contact with the film bubble inside the connecting plate 110. When the airflow comes into contact with the film bubble, it cools the surface of the film bubble. After passing through the through hole 15, the film bubble passes between a pair of guide rollers 17. A pair of guide rollers 17 and auxiliary rollers 18 guide the film bubble. After production is completed, the winding machine 19 is turned on through the control box 7 and the film bubble is wound onto the winding machine 19. The winding machine 19 winds up the film bubble. A connecting plate 110 is provided on the second support plate 14, and an air storage box 111 is fixed on the first support plate 12. An air supply pipe 113 is connected to the air pump 112, and multiple air outlet pipes 114 are connected to the connecting plate 110. During use, the air in the air storage box 111 can be blown to the surface of the film bubble through the multiple air outlet pipes 114 to cool the surface of the film bubble. This reduces the possibility of the film bubble being damaged due to overheating during the winding process because the film bubble is not thoroughly cooled by natural cooling during use.

[0024] Please see Figures 1-4 As shown, multiple baffles 2 are fixedly connected to the connecting plate 110. The baffles 2 are arranged in an array and are corresponding to the air outlet pipe 114. When air is blown out through the multiple air outlet pipes 114 connected to the connecting plate 110, it comes into contact with the baffles 2. When the air comes into contact with the baffles 2, the air is blocked by the baffles 2. When the baffles 2 block the air, the air is dispersed. The dispersed air can better contact the surface of the membrane bubble. By fixing multiple baffles 2 to the connecting plate 110, the airflow ejected from the air outlet pipe 114 can be dispersed during use. The dispersed air can better contact the surface of the membrane bubble, thus achieving a better cooling effect.

[0025] Please see Figures 3-4 As shown, a connecting rod 3 is fixedly connected to the baffle 2, and a connecting block 31 is rotatably connected to the end of the connecting rod 3. Multiple baffles 32 are fixedly connected to the connecting block 31. When air is ejected from the outlet pipe 114, it comes into contact with the baffle 2. When the air comes into contact with the baffle 2, the baffle 2 disperses the air. Some of the undispersed airflow moves along the direction of the baffle 2. When the air moves to a designated position, it comes into contact with the baffle 32. When the flowing air comes into contact with the baffle 32, the baffle 32 rotates. When the baffle 32 rotates, it further disturbs the air near the baffle 32. The disturbed airflow comes into contact with the surface of the membrane bubble. By rotatably connecting the connecting block 31 to the end of the connecting rod 3 and fixing multiple baffles 32 to the connecting block 31, the baffles 32 can rotate when the air moves along the direction of the baffle 2 to a designated position during use, further disturbing the air, thereby achieving a better cooling effect.

[0026] Please see Figure 4 As shown, the baffle plate 2 has multiple air outlets 4 arranged in an array. When air is ejected from the air outlet pipe 114 and moves along the direction of the baffle plate 2, some air passes through the air outlets 4 on the baffle plate 2. When air passes through the air outlets 4 on the baffle plate 2, the air velocity increases. By having multiple air outlets 4 on the baffle plate 2, the air velocity can be increased during use, thereby enhancing the cooling effect of air on the membrane bubble.

[0027] Please see Figure 5As shown, a water tank 5 is fixedly connected to the first support plate 12, a water pump 51 is connected to the water tank 5, and a water supply pipe 52 is connected to the water pump 51. Multiple connecting posts 53 are fixedly connected to the connecting plate 110, and a sprinkler plate 54 is fixedly connected to each connecting post 53. The water supply pipe 52 and the sprinkler plate 54 are connected. During the membrane bubble production process, the water pump 51 is controlled to start via the control box 7. When the water pump 51 starts, the water inside the water tank 5 is sent into the sprinkler plate 54 through the water supply pipe 52. After the water enters the sprinkler plate 54, it sprays water through multiple small holes on the sprinkler plate 54. When water is sprayed onto the surface of the membrane bubble, it can cool the membrane bubble. When the water stays on the surface of the membrane bubble, the air blown out at the air outlet 114 comes into contact with the surface of the membrane bubble, the water on the surface of the membrane bubble evaporates. When the water evaporates, the surface of the membrane bubble is further cooled. By fixing a water spray plate 54 on the connecting column 53, a water supply pipe 52 is connected to the water spray plate 54, a water pump 51 is connected to the end of the water supply pipe 52, and a water tank 5 is connected to the water pump 51, the water inside the water tank 5 can be sprayed onto the surface of the membrane bubble through the water spray plate 54 during use, thereby cooling the membrane bubble.

[0028] Please see Figure 5 As shown, a sponge block 6 is fixedly attached to the sprinkler plate 54. The sponge block 6 is located between the first support plate 12 and the sprinkler plate 54. When water is sprayed from the sprinkler plate 54, the water flow comes into contact with the membrane bubble and cools the surface of the membrane bubble. When a small amount of water does not completely evaporate from the surface of the membrane bubble, the water flow will converge. When the water flow converges, the water flow moves towards the first support plate 12. When the water flow moves to the designated position, the water flow comes into contact with the sponge block 6. At this time, the sponge block 6 absorbs and collects the water flow. By fixing the sponge block 6 to the sprinkler plate 54, the water flow that has not evaporated from the surface of the membrane bubble can be collected during use, reducing the situation where water falls onto the surface of the first support plate 12 and causes pollution to the first support plate 12.

[0029] Working principle: During operation, the control box 7 installed on the first support column 11 controls the opening of the blown film machine 115 and the raw material box 116. When the raw material box 116 is opened, the raw material in the raw material box 116 is fed into the blown film machine 115. After the blown film machine 115 processes the raw material, it blows the raw material into a film bubble. After the film bubble is formed, it passes through the through hole 15 and the inside of the connecting plate 110. When the film bubble passes through the connecting plate 110, the air pump 112 is turned on by the control box 7. When the air pump 112 is turned on, the air inside the air storage box 111 is sent into the connecting plate 110 through the air supply pipe 113. When the air enters the connecting plate 110, it is ejected from the multiple air outlet pipes 114 connected to the connecting plate 110. The ejected airflow and the air inside the connecting plate 110... When the airflow comes into contact with the membrane bubble, it cools the surface of the membrane bubble. After passing through the through-hole 15, the membrane bubble passes between a pair of guide rollers 17. After passing through the pair of guide rollers 17, the pair of guide rollers 17 and the auxiliary roller 18 guide the membrane bubble. After production is completed, the winding machine 19 is turned on through the control box 7, and then the membrane bubble is wound on the winding machine 19. The winding machine 19 winds up the membrane bubble. When air is blown out through the multiple air outlet pipes 114 connected on the connecting plate 110, it comes into contact with the baffle plate 2. When the air comes into contact with the baffle plate 2, the air is blocked by the baffle plate 2. When the baffle plate 2 blocks the air, the air is dispersed. The dispersed air can better contact the surface of the membrane bubble. When the air is sprayed out from the air outlet pipe 114, it comes into contact with the baffle plate 2. When air comes into contact with the baffle 2, the baffle 2 disperses the air. Some of the undispersed airflow moves along the direction of the baffle 2. When the air reaches a designated position, it comes into contact with the baffle 32. The baffle 32 rotates when it comes into contact with the flowing air, further agitating the air near it. The agitated airflow then contacts the surface of the membrane bubble. When air is ejected from the outlet pipe 114 and moves along the direction of the baffle 2, some air passes through the outlet holes 4 on the baffle 2. As the air passes through the outlet holes 4, the air velocity increases. During membrane bubble production, the water pump 51 is turned on by the control box 7. When the water pump 51 is turned on, it pumps water from inside the water tank 5. Water is supplied through the water pipe 52 into the sprinkler plate 54. Once inside the sprinkler plate 54, the water flows through multiple small holes and sprays onto the membrane bubble surface. This spray cools the membrane bubble. When the water reaches the membrane bubble surface, the air blown out from the air outlet 114 evaporates the water, further cooling the surface. When water is sprayed from the sprinkler plate 54, it contacts the membrane bubble, cooling its surface. If a small amount of water doesn't completely evaporate, it converges and moves towards the first support plate 12. When the water reaches the designated position, it contacts the sponge block 6.At this time, the sponge block 6 absorbs and collects the water flow, reducing the chance of water falling onto the surface of the first support plate 12 and causing contamination.
