Description

Technical Field

[0001] This application relates to the field of blown film apparatus technology, and in particular to a clean blown film apparatus with a cooling function. Background Technology

[0002] Film blowing machines use air blowers in an air ring to blow processed plastic particles into film bubbles, thus producing films. However, film blowing machines are relatively large and are usually located in factories. Because the preceding processes require the plastic particles to be melted and extruded into a liquid state, the temperature inside the factory is relatively high. In hot summers, the temperature is even higher, resulting in higher temperatures blowing from the air ring's air blowers, which may lead to low film blowing efficiency. Utility Model Content

A cylindrical exhaust pipe is coaxially arranged around the air outlet, extending away from the air ring.

The air inlet and air outlet are arranged in a ring at intervals. The air inlet is connected to an air inlet branch pipe through a pipe. The air inlet branch pipe is connected to an air inlet fan through a pipe. The air outlet is connected to an air outlet confluence pipe through a pipe. The air outlet confluence pipe is connected to an exhaust fan through a pipe. A refrigeration device is installed in the pipe between the air inlet fan and the air inlet branch pipe.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] The following is in conjunction with the appendix Figure 1-2This application provides a further detailed description. An embodiment of this application discloses a cleaning blown film device with a cooling function. It includes an air ring 1 with an air outlet 101. The air outlet 101 is annular, and the blown air diffuses outwards to inflate the film bubble. A cylindrical exhaust pipe 2 is coaxially arranged around the air outlet 101, extending away from the air ring 1. Air is blown through the air outlet 101 to form plastic particles into film bubbles, and then the air inside the film bubbles is extracted through the exhaust pipe 2. This accelerates the cooling of the film blown out by the air ring 1, increasing equipment output. Furthermore, it achieves air circulation inside the film bubble, controlling the removal of odors and preventing the accumulation of VOCs or particulate dust inside the film bubble, thus achieving a cleaning function inside the film bubble. To prevent insufficient suction of air from the sides of the exhaust pipe 2 due to the pipe opening being located at the top end, this design is designed to prevent such odors from being extracted. The end face of the exhaust pipe 2 away from the air ring 1 is sealed, and an exhaust hole is opened on the outer circumferential surface of the end of the exhaust pipe 2 away from the fan, so that the exhaust pipe 2 can more effectively draw air from the membrane bubble and prevent particles, dust and other impurities from escaping from the suction range of the exhaust pipe 2 along the edge of the membrane bubble.

[0023] The bottom of the air ring 1 is provided with an air inlet (not shown in the figure) and an air outlet (not shown in the figure). The air inlet is connected to the air outlet 101 of the air ring 1, and the exhaust pipe 2 is connected to the air outlet. The air inlet and air outlet are arranged in a ring at intervals. The ring arrangement of the air inlet helps to increase the air volume of the air outlet 101, so that the air blown out by the air outlet 101 can be blown out evenly from all angles. The number of ring-shaped air inlets and air outlets is set as needed according to actual conditions. The air inlet is connected to the air inlet diversion pipe 3 through a pipe. The air inlet diversion pipe 3 is connected to the air inlet fan 5 through a pipe. The air delivered by the fan is sent to each air inlet through the air inlet diversion pipe 3. The air outlet is connected to the air outlet converging pipe 4 through a pipe. The air outlet converging pipe 4 is connected to the exhaust fan 6 through a pipe, so that the air extracted from each air outlet is converged to the exhaust fan 6 and discharged by the exhaust fan 6. A refrigeration device 7 is installed in the pipe between the air inlet fan 5 and the air inlet branch pipe 3 to reduce the blowing temperature of the air outlet 101. Specifically, the refrigeration device 7 can be a directly installed chiller, or it can use a circulating cooling water pipe to recycle the cold energy in the equipment area.

[0024] Furthermore, a support frame is connected to the bottom of the air ring 1. The support frame includes two hollow bases, which serve as the inlet split pipe 3 and the outlet confluence pipe 4, respectively. Given that the air inlet and outlet of the air ring 1 are arranged in a ring shape, integrating the inlet split pipe 3 and the outlet confluence pipe 4 into the support frame avoids pipe clutter, simplifies the pipe layout, improves the compactness and overall integrity of the equipment structure, and reduces the complexity of subsequent maintenance.

[0025] Furthermore, the fan is equipped with a temperature-controlled air outlet 8 that blows air towards the fan's air outlet 101. The temperature-controlled air outlet 8 is arranged in a ring around the fan's air outlet 101, and a temperature control device is installed inside the temperature-controlled air outlet 8. The temperature-controlled air outlet 8 is connected to a temperature-controlled fan (not shown in the figure) via a pipe. Air is blown through the temperature-controlled air outlet 8 onto the membrane bubble blowing from the air outlet 101 of the air ring 1, thereby controlling the temperature of the membrane bubble from the outside. Specifically, the temperature control device can be a heating rod, which heats the air blown from the temperature-controlled air outlet 8 through electric heating; or it can be a circulating cooling water pipe, which cools the air blown from the temperature-controlled air outlet 8. By controlling the temperature of the membrane bubble from the outside, the temperature can be increased to thin the membrane when it is too thick, or decreased to thicken the membrane when it is too thin. Since the temperature-controlled air outlets 8 are arranged in a ring around the fan's air outlet 101, there are multiple temperature-controlled air outlets 8. The temperature control device can be configured to use electric heating rods uniformly in cold environments or cooling water pipes uniformly in hot environments, depending on the overall operating environment of the equipment. Furthermore, the temperature-controlled air outlet 8 is equipped with an airflow control device, such as an automatic door or an automatic valve in the pipes connected to the temperature-controlled air outlet 8. This allows the airflow of the temperature-controlled air outlet 8 to be controlled, enabling the electric heating rods and cooling water pipes to be simultaneously and intermittently installed in the ring-shaped temperature-controlled air outlet 8, and allowing the outlet 8 to blow hot or cold air electrically.

[0026] Working Principle: The air ring 1 is installed within the entire blown film machine and connected to the preceding and following mechanisms. When the inlet fan 5 is started, the air generated by the inlet fan 5 enters the distribution pipe through a duct and is then diverted to the air inlet of the air ring 1 through multiple branch pipes, subsequently being blown out from the blowout 101. As the air blown out from the blowout 101 flows upwards, it carries internal particulate dust and plastic odors upwards, which are then sucked away through the exhaust duct 2. The sucked-out air enters the confluence pipe from the air outlet of the air ring 1 and is then discharged by the exhaust fan 6, thus promoting airflow inside the blown film bubble at the blowout 101 of the air ring 1, achieving the effect of automatically cleaning the air inside the bubble. When the external environment is hot, the cooling device 7 is activated, cooling the air blown out by the inlet fan 5, thereby lowering the temperature of the air blown out from the blowout 101 of the air ring 1.
