Description

Technical Field

[0001] This utility model relates to the field of plastic film blowing technology, and in particular to a high-efficiency and energy-saving plastic film blowing device. Background Technology

[0002] Film drawing is a crucial step in the blown film process. After the film is extruded from the die and initially shaped, it needs to be pulled upwards from the die by a film drawing device to ensure continuous production. This upward pulling process is called film drawing. The uniformity of film thickness largely depends on the stability of the film drawing process. If the film drawing speed is uneven, such as varying speeds, it will cause uneven stress on the film during stretching, which may lead to thickness deviations, with some areas becoming thinner and others thicker. Appropriately increasing the film drawing speed can produce more film per unit time, but the film drawing speed cannot be increased arbitrarily, as excessive speed may exceed the film's stretching limit, causing the film to break and reducing production efficiency. Utility Model Content

[0003] This utility model mainly provides a high-efficiency and energy-saving plastic film blowing device that assists workers in the film pulling process during the film blowing process, thereby improving processing efficiency and reducing the occurrence of burns.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency and energy-saving plastic film blowing device, comprising: a first base; a second base fixedly connected to the top of the first base near one side edge; an electric push rod fixedly connected to the top of the second base; a push block fixedly connected to the output end of the electric push rod; an air nozzle fixing column fixedly connected to the top of the first base near the center; a high-speed air nozzle fixedly connected to the top of the air nozzle fixing column; a gas balance dispersion grid fixedly connected to the inner surface of the air nozzle fixing column near the top; a gas dispersion cone connecting rod fixedly connected to the bottom of the gas balance dispersion grid; a first gas dispersion cone fixedly connected to the outer surface of the gas dispersion cone connecting rod; a film blowing machine housing fitted onto the outer surface of the air nozzle fixing column; the bottom of the film blowing machine housing fixedly connected to the top of the first base; a third base fixedly fitted onto the outer surface of the film blowing machine housing near the top; a column sliding plate fixedly connected to the top of the third base; and the top of the column sliding plate fitting... The device includes a cross-shaped sliding disk with several blown film pushing blocks slidably connected to its top. Limiting posts are fixedly connected to the outer surfaces of the pushing blocks, and the outer surfaces of these posts slide against the inner surfaces of the sliding disk. A sliding block is fixedly connected to the bottom of each limiting post. A high-speed air nozzle is fixedly connected to the top of the air nozzle fixing post. The high-speed air nozzle provides strong and stable airflow for blown film, enabling the molten plastic to be rapidly inflated into a thin film, thus increasing the forming speed and processing efficiency. A gas balance dispersion grid evenly disperses the incoming gas, making the blown gas pressure more uniform and ensuring uniform stress on all parts of the film during inflation. This helps produce films with uniform thickness and good quality, reducing scrap rates and improving product quality and production efficiency. The gas dispersion cone connecting rod and the first gas dispersion cone further optimize the gas dispersion effect, making the gas flow more rational and conducive to uniform film forming. It also reduces instability factors such as localized overheating or overcooling of the film due to uneven gas distribution.

[0005] Preferably, the outer surface of the sliding block and the groove opened on the column sliding disk are slidably fitted together. The top of the cross sliding disk is rotatably fitted with a push block fixedly connected to the output end of the electric push rod with an embedded rotating connecting ring through the groove. The advantage is that the electric push rod can provide a stable and precisely controllable linear thrust. This allows the position and force of the push block to be accurately adjusted according to the process requirements during the operation of the blown film device, thereby performing precise pushing operations on the relevant components. For example, in the process of film stretching or cooperating with other components, precise displacement control can be achieved, improving the processing accuracy and stability, and thus improving processing efficiency. At the same time, the automated electric push rod operation reduces the uncertainty and labor intensity of manual operation, reduces production errors caused by improper manual operation, and workers do not need to directly perform strong and unstable pushing operations manually, reducing the risk of workers being burned when close to moving parts during operation.

[0006] Preferably, the top of the cross-shaped sliding disk is fixed with several connecting sliding posts, and the outer surface of the embedded rotating connecting ring is rotatably fitted with the flower-shaped sliding disk through a groove. The top of the air nozzle fixing post is fixedly connected with a high-speed air nozzle. The high-speed air nozzle can provide strong and stable airflow power for blown film, so that the plastic melt can be quickly blown into a film, improving the forming speed of blown film and thus improving processing efficiency. The gas balance dispersion grid can evenly disperse the incoming gas, making the blown gas pressure more uniform, ensuring that the film is subjected to uniform force in all parts during the blowing process, which helps to produce films with uniform thickness and good quality, reduce scrap rate, and improve product quality and production efficiency. The gas dispersion cone connecting rod and the first gas dispersion cone further optimize the gas dispersion effect, making the gas flow more reasonable, which is conducive to the uniform forming of the film, and also reduces unstable factors such as local overheating or overcooling of the film due to uneven gas distribution.

[0007] Preferably, the outer surface of the flower-shaped sliding disc is provided with a first sliding groove and a second sliding groove. The bottom of the blown film machine housing and the top of the first base are fixedly connected. The blown film machine housing provides a closed and stable working environment for the internal blown film components. It can prevent external dust, impurities, etc. from entering the device and affecting the blown film process and film quality, ensuring a clean and stable production environment, thereby improving film quality and production efficiency. In addition, the housing has a certain heat insulation effect, which can reduce the heat transfer from internal high-temperature components or gases to the external environment, reduce the risk of workers being burned by accidental contact with high-temperature components, provide workers with a relatively safe operating environment, and ensure the safety of production operations.

[0008] Preferably, the outer surface of the connecting sliding column and the inner surface of the first sliding groove are slidably fitted together; the outer surface of the limiting column and the inner surface of the second sliding groove are slidably fitted together; the outer surface of the sliding block and the groove opened on the column sliding disk are slidably fitted together; several blown film pushing blocks are slidably connected to the top of the cross sliding disk; and the outer surface of the limiting column and the inner surface of the cross sliding disk are slidably fitted together. This sliding fit allows components such as the blown film pushing blocks to move flexibly and adjust their positions in the plane. During the blown film process, the blown film pushing blocks can precisely adjust their positions and apply appropriate forces to the film according to the film forming condition and process requirements, such as extruding or assisting in forming the film, improving the shape accuracy and quality of the film, thereby improving processing efficiency. At the same time, this precise sliding control method reduces the need for workers to manually adjust the position of components, reducing the risk of workers being burned due to proximity to moving parts or unstable operation, thus ensuring worker safety.

[0009] Preferably, an external transmission device disk is fixedly connected to the top of the connecting sliding column, and a first fixed column is fixedly connected to the bottom of the external transmission device disk near the center. The top of the cross sliding disk is rotatably fitted with an embedded rotating connecting ring through a groove. The outer surface of the flower-shaped sliding disk is rotatably fitted with the embedded rotating connecting ring through a groove. The outer surface of the connecting sliding column and the first sliding groove of the flower-shaped sliding disk are slidably fitted together. These structures realize complex motion coordination between multiple components. Through the combined motion of rotation and sliding, the film can be adjusted and operated in different directions and angles.

[0010] Preferably, a blown film limiting column is fixedly connected to the bottom of the first fixed column. The outer surface of the blown film limiting column and the outer surface of the blown film pushing block cooperate with each other. An external transmission device disk is fixedly connected to the top of the connecting sliding column. The external transmission device disk is connected to the blown film limiting column through the first fixed column. The outer surface of the blown film limiting column and the outer surface of the blown film pushing block cooperate with each other. The external transmission device disk facilitates the connection with external raw material supply equipment or other related equipment, realizes stable transmission and supply of raw materials, ensures the continuity of the blown film process, and improves production efficiency. The blown film limiting column can accurately limit and guide the blown film raw materials, making the raw materials more concentrated and stable when entering the blown film process.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, through the cooperation of the electric push rod, the push block and various sliding structures, the linear thrust of the electric push rod, the cooperation between the sliding block and the column sliding plate, and the cooperation between the limiting column and the cross sliding plate, the processing efficiency is improved. The blown film push block and other components can move and adjust their positions flexibly in the plane. Appropriate force is applied to the film according to the film forming situation and process requirements. This precise motion control method reduces the uncertainty and labor intensity of manual operation, reduces production errors caused by improper manual operation, and reduces the risk of workers being burned when they get close to moving parts during operation.

[0013] 2. In this utility model, the air nozzle fixing column and other related structures provide stable airflow power for blown film, ensuring uniform gas dispersion and reasonable flow, which can improve blown film speed, efficiency and film quality, and reduce the risk of worker burns. The blown film machine shell provides a closed and stable environment with heat insulation, which can keep the environment clean, improve film quality and reduce the risk of worker burns. The external transmission equipment panel and other components can achieve stable transmission and accurate guidance of raw materials, ensuring the continuity of blown film and the consistency of film quality, improving efficiency and reducing the risk of worker burns.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

The outer surface of the limiting posts 19 and the inner surface of the cross sliding disk 27 are slidably attached. A sliding block 18 is fixedly connected to the bottom of the limiting posts 19. A high-speed air nozzle 17 is fixedly connected to the top of the air nozzle fixing post 16. The high-speed air nozzle 17 can provide strong and stable airflow power for blown film, so that the plastic melt can be quickly blown into a film, which improves the forming speed of blown film and thus improves processing efficiency. The gas balance dispersion grid 44 can evenly disperse the incoming gas, making the blown gas pressure more uniform, ensuring that the film is subjected to uniform force in all parts during the blowing process, which helps to produce films with uniform thickness and good quality, reduce scrap rate, and improve product quality and production efficiency. The gas dispersion cone connecting rod 41 and the first gas dispersion cone 42 further optimize the gas dispersion effect, making the gas flow more reasonable, which is conducive to the uniform forming of the film, and also reduces unstable factors such as local overheating or overcooling of the film due to uneven gas distribution.

[0023] like Figure 1-5 As shown, the outer surface of the sliding block 18 and the groove opened in the column sliding disk 2 slide in contact. The top of the cross sliding disk 27 is rotatably attached to the output end of the electric push rod 12, which is fixedly connected to the rotating connecting ring 21. The advantage is that the electric push rod 12 can provide a stable and precisely controllable linear thrust. This allows the position and force of the push block 15 to be accurately adjusted according to the process requirements during the operation of the blown film device, thereby performing precise pushing operations on the relevant components. For example, in the process of film stretching or cooperating with other components, precise displacement control can be achieved, improving the processing accuracy and stability, and thus improving processing efficiency. At the same time, the automated operation of the electric push rod 12 reduces the uncertainty and labor intensity of manual operation, reduces production errors caused by improper manual operation, and workers do not need to directly perform strong and unstable pushing operations manually, reducing the risk of workers being burned when they are close to moving parts during operation.

[0024] like Figure 1-5 As shown, several connecting sliding posts 22 are fixed to the top of the cross sliding disk 27. The outer surface of the embedded rotating connecting ring 21 is fitted with a flower-shaped sliding disk 28 through a groove. A high-speed air nozzle 17 is fixedly connected to the top of the air nozzle fixing post 16. The high-speed air nozzle 17 can provide strong and stable airflow power for blown film, so that the plastic melt can be quickly blown into a film, which improves the forming speed of blown film and thus improves processing efficiency. The gas balance dispersion grid 44 can evenly disperse the incoming gas, making the blown gas pressure more uniform, ensuring that the film is subjected to uniform force in all parts during the blowing process, which helps to produce films with uniform thickness and good quality, reduce scrap rate, and improve product quality and production efficiency. The gas dispersion cone connecting rod 41 and the first gas dispersion cone 42 further optimize the gas dispersion effect, making the gas flow more reasonable, which is conducive to the uniform forming of the film, and also reduces unstable factors such as local overheating or overcooling of the film due to uneven gas distribution.

[0025] like Figure 1-5 As shown, the outer surface of the flower-shaped sliding disk 28 is provided with a first sliding groove 23 and a second sliding groove 25. The bottom of the blown film machine housing 13 and the top of the first base 1 are fixedly connected. The blown film machine housing 13 provides a closed and stable working environment for the internal blown film components. It can prevent external dust, impurities, etc. from entering the device and affecting the blown film process and film quality, ensuring the cleanliness and stability of the production environment, thereby improving the quality of the film and production efficiency. In addition, the housing has a certain heat insulation effect, which can reduce the heat transfer from the internal high-temperature components or gases to the external environment, reduce the risk of workers being burned by accidental contact with high-temperature components, provide workers with a relatively safe operating environment, and ensure the safety of production operations.

[0026] like Figure 1-5 As shown, the outer surface of the connecting sliding column 22 and the inner surface of the first sliding groove 23 are slidably fitted together; the outer surface of the limiting column 19 and the inner surface of the second sliding groove 25 are slidably fitted together; the outer surface of the sliding block 18 and the groove opened in the column sliding disk 2 are slidably fitted together; and several blown film pushing blocks 31 are slidably connected to the top of the cross sliding disk 27. This sliding fit allows components such as the blown film pushing blocks 31 to move flexibly and adjust their position within a plane. During the blown film process, the blown film pushing blocks 31 can precisely adjust their position and apply appropriate force to the film according to the film forming condition and process requirements, such as extruding or assisting in forming the film, improving the shape accuracy and quality of the film, thereby increasing processing efficiency. Simultaneously, this precise sliding control method reduces the need for workers to manually adjust the position of components, reducing the risk of workers being burned due to proximity to moving parts or unstable operation, thus ensuring worker safety.

[0027] like Figure 1-5 As shown, an external transmission device disk 26 is fixedly connected to the top of the connecting sliding column 22, and a first fixed column 43 is fixedly connected to the bottom of the external transmission device disk 26 near the center.

[0029] Working principle: The electric actuator 12 serves as a power source, receiving control signals and converting electrical energy into linear thrust. The push block 15, fixedly connected to the output end of the electric actuator 12, moves precisely in a straight line under its action, causing the blown film limiting column 4 and the blown film pushing block 31 to cooperate, ensuring material concentration. The blown film pushing block 31 pushes the material to the outer surface of the blown film limiting column 4, forming a closed space through compression. The plastic material reaches the vicinity of the high-speed jet nozzle 17 at the top of the air nozzle fixing column 16. The high-speed jet nozzle 17 blows out a strong and stable airflow, rapidly inflating the molten plastic into a thin film. The gas is evenly dispersed as it passes through the gas balance dispersion grid 44, making the blown gas pressure more uniform. Then, it passes through the gas dispersion cone connecting rod 41 and... The first gas dispersion cone 42 further optimizes the dispersion effect, making the gas flow more reasonable and accurately entering the subsequent blown film process, ensuring the continuity of the blown film process and improving production efficiency. The blown film machine shell 13 provides a closed and stable working environment for the internal blown film components. It can prevent external dust, impurities, etc. from entering the device and affecting the blown film process and film quality, ensuring a clean and stable production environment, thereby improving film quality and production efficiency.
