Description

Technical Field

[0001] The utility model relates to the technical field of film blowing machines, and specifically relates to a plastic production film blowing machine. Background Art

[0002] The film blowing machine heats plastic raw materials to a molten state and then extrudes the molten plastic to form a film body. During the cooling process, the film body is blown by air to stabilize its shape and is finally wound into a coil. The cooling and winding mechanisms of the machine ensure the uniform cooling of the film body and high-quality production;

[0003] At present, there are some problems in the actual use of film blowing machines. When the extrusion thickness of the film body needs to be increased, the cooling mechanism can only improve the cooling effect by increasing the power and cannot solve the problem of enhanced cooling function while maintaining the same power. Therefore, we propose a plastic production film blowing machine to solve the above problems. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a plastic production film blowing machine to solve the problem of increased cooling function under the same power.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A plastic production film blowing machine includes a main body mechanism, and an adjusting mechanism is installed on the main body mechanism. The adjusting mechanism includes a bottom plate fixedly connected to a base, an electric push rod fixedly connected to the top of the bottom plate, a cooling cover fixedly connected to the top of the electric push rod. Four sliding rods are symmetrically arranged inside the cooling cover. A first exhaust air shell and a second exhaust air shell are arranged outside the sliding rods. Conical air outlets are fixedly connected to the upper and lower sides of the first exhaust air shell, and square air outlets are fixedly connected to the upper and lower sides of the second exhaust air shell.

[0006] By adopting the above technical scheme, the electric push rod adjusts the height of the cooling cover to precisely match the height of the film body for cooling adjustment. The four sliding rods inside the cooling cover can support the first exhaust air shell and the second exhaust air shell, which is convenient for their replacement work. The first exhaust air shell and the second exhaust air shell in the adjusting mechanism cooperate with the conical air outlets and the square air outlets to realize multi-directional and multi-mode cold air delivery. The setting of the conical air outlets helps to form a concentrated and efficient cold air flow for rapid cooling, thereby improving the cooling effect of the system and the overall working efficiency. The cooling cover can refer to the cooling cover in the patent number CN 220031168.

[0007] Further, the main body mechanism includes a machine body installed on the top of the base, a film outlet is installed on one side of the machine body, and a film body is inside the film outlet.

[0008] By adopting the above technical scheme, the continuous output of the film can be effectively realized. This configuration enables the film body to smoothly pass through the film outlet, thereby improving the production efficiency and the output stability of the film.

[0009] Furthermore, a cooling mechanism is installed on the top of the main body mechanism. The cooling mechanism includes a mounting plate, an activity slot on the mounting plate, a filter screen plate installed in the activity slot, an exhaust fan installed on one side of the filter screen plate, a motor connected to one side of the exhaust fan, and one end of an air delivery pipe installed on the exhaust fan, and the other side of the air delivery pipe is connected to the inside of a cooling cover.

[0010] By adopting the above technical solution, including the mounting plate and the activity slot, the function of the cooling system is effectively improved. The filter screen plate is located in the activity slot, which helps to filter impurities in the air. The design of the activity slot facilitates the replacement of the filter screen plate. The exhaust fan is connected to the motor and can generate a strong air flow to guide the air into the inside of the cooling cover through the air delivery pipe. This configuration ensures the efficiency and stability of the cooling process, thereby improving the performance and reliability of the overall system.

[0011] Furthermore, a winding mechanism is installed on the top of the main body mechanism. The winding mechanism includes support plates symmetrically installed on the top of a base. A first mounting plate is installed on one side of the support plates. A first motor is installed inside the first mounting plate. The output end of the first motor is connected to a transmission shaft, and a roller is connected to the outside of the transmission shaft.

[0012] By adopting the above technical solution, the winding and storage of materials can be carried out efficiently. The first mounting plate on the support plate and the first motor thereon drive the transmission shaft, which is further connected to the roller. This configuration ensures the stability and efficiency of the winding process, can quickly and accurately complete the winding task of materials, thereby improving the convenience of operation and the overall function of the system.

[0013] Furthermore, chutes are provided on the outer sides of the first exhaust air shell and the second exhaust air shell. The chutes are adapted to sliding rods, and limit members are provided on both sides of the sliding rods.

[0014] By adopting the above technical solution, chutes are provided on the outer sides of the first exhaust air shell and the second exhaust air shell and are matched with the sliding rods, which can achieve more flexible and accurate installation and adjustment.

[0036] Refer to Figure 4 , chutes are provided on the outside of the first exhaust housing 206 and the second exhaust housing 207. The chutes are adapted to the slide bars 205. Limit members 208 are provided on both sides of the slide bars 205. By providing chutes on the outside of the first exhaust housing 206 and the second exhaust housing 207 and cooperating with the slide bars 205, more flexible and precise installation and adjustment can be achieved.

This adjustability not only allows optimizing the air flow and cooling effect according to actual needs, but also improves the adaptability and efficiency of the system. This setting simplifies the maintenance work and facilitates inspection and cleaning.

[0038] The implementation principle of this embodiment is as follows: First, the staff heats the raw materials to a molten state, starts the electric push rod 202, raises the cooling cover 203 to a height matching the film body 104, and then inserts the filter screen plate 303 into the movable groove 302. Start the motor 305, and the motor 305 drives the exhaust fan 304 to work. The exhaust fan 304 exhausts air and transmits the air into the cooling cover 203 through the air delivery pipe 306. Move the second exhaust air shell 207 into the cooling cover 203 along the slide rod 205 and limit it through the limiting member 208. Extrude the film body 104 through the film outlet hole 103 of the main body mechanism 1, and pass the film body 104 through the second exhaust air shell 207 and the cooling cover 203 to cool the film body 104. Start the first motor 403, the first motor 403 drives the transmission shaft 404, and the transmission shaft 404 drives the roller 405 to rotate to wind up the film body 104. When the film body 104 is relatively thick, move the second exhaust air shell 207 outside the cooling cover 203 and on the slide rod 205, move the first exhaust air shell 206 into the cooling cover 203, and limit it through the limiting member 208 on the slide rod 205. Since the tapered air outlet 209 in the first exhaust air shell 206 gradually becomes smaller, the wind speed passing through the shell with a smaller air outlet is faster under the same power, thereby accelerating the cooling function.
