Description

Technical Field

[0001] This utility model relates to the field of film production, and in particular to an air-cooling device for film. Background Technology

[0002] During the production and processing of film, the film undergoes several complex processes such as coating, drying, and exposure. After these processes, the film is often at a high temperature due to heat accumulation. The subsequent packaging process has strict requirements on the temperature of the film. Excessive temperature may not only affect the sealing and flatness of the packaging, but may also have potential adverse effects on the shelf life and performance of the film. In order to ensure that the film can smoothly enter the subsequent rapid packaging process and ensure the stable and reliable quality of the packaged film, timely and effective cooling of the film is particularly important.

[0003] In existing film production processes, the application of traditional air-cooling devices is quite common. Typically, such air-cooling devices mainly consist of a basic air-cooling system composed of a fan, air duct, and air outlet, as well as some auxiliary structures to ensure a basic operating environment. The fan, as the power core, draws in outside air and guides the airflow through a simply designed air duct, causing it to blow from the air outlet onto the film surface that is moving at a uniform speed on the conveyor belt.

[0004] In the existing technology, the following defects exist: In terms of air cooling efficiency, the air duct structure of traditional air cooling devices is simple and lacks optimized design for airflow. Since it only relies on the original power output of the fan, the airflow is not effectively accelerated and reasonably distributed during the flow through the air duct. As a result, the wind speed is relatively low when the blown air reaches the film surface and the air coverage is not uniform enough. Consequently, the film cooling speed is slow, and it is difficult to reduce the film temperature to a suitable range for packaging in a short time. This seriously slows down the rhythm of the entire production process and reduces production efficiency. Therefore, an air cooling device for film is proposed to solve the above problems.

[0034] 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 protection scope of the present utility model.

[0035] Reference Figures 1-3 This utility model provides an embodiment of a film air-cooling device, including a conveyor box 1. A fan 2 is installed on the side wall of the conveyor box 1. A connecting pipe 3 is fixedly connected to the left end of the fan 2. A conical groove is formed on the inner wall of the connecting pipe 3. The conical groove is wider at the top and narrower at the bottom. Air can smoothly enter the conical groove from the wider upper part. As the groove gradually narrows, the airflow is guided and converged, as if it is being gathered, so that the airflow velocity can be increased after passing through the conical groove, thereby enhancing the strength and impact of the subsequent blown air. A fixing pipe 4 is fixedly connected to the outer wall of the connecting pipe 3. The fixing pipe 4 mainly serves as a connecting sleeve 5, and... The sliding joint between the fixed tube 4 and the sleeve 5 is sealed using existing technology to ensure that there is no air leakage between the fixed tube 4 and the sleeve 5. The sleeve 5 is slidably connected to the outer wall of the fixed tube 4, and the movable tube 6 is fixedly connected to the end of the sleeve 5. The bottom end of the movable tube 6 is also provided with a conical groove, which can allow air to be quickly discharged from the conical groove and blow onto the film surface to improve its heat dissipation efficiency. The top end of the movable tube 6 is fixedly connected to a slider 7, and the inner wall of the slider 7 is provided with a drive mechanism. The inner wall of the conveyor box 1 is provided with a conveyor belt 16, which can transport the produced film to the packaging point. The inner wall of the conveyor box 1 is provided with a filter assembly.

[0036] The drive mechanism includes a bidirectional lead screw 8, which is also often called a ball screw pair or ball screw. It is a mechanical transmission component that converts rotary motion into linear motion or vice versa. The bidirectional lead screw 8 is set on the inner wall of the slider 7, and a motor 9 is fixedly connected to the end of the bidirectional lead screw 8.

[0037] Reference Figures 5-7The filter assembly includes a filter box 11, which is equipped with an exhaust pipe to discharge air. An L-tube 10 is fixedly connected to the side wall of the filter box 11. A filter frame 12 is detachably installed on the inner wall of the filter box 11, and the filter frame 12 has a filter screen that adsorbs impurities and odors, preventing odors from affecting the surrounding environment. A lever 15 is elastically connected to the top inner wall of the filter frame 12 via a return spring 14. The L-tube 10 allows hot air to enter the filter box 11 from the delivery box 1. A guide fan 13 is installed on the inner wall of the L-tube 10 to guide the hot air into the L-tube 10. (This is existing technology and will not be discussed further here.) To elaborate further, the top inner wall of the filter frame 12 is fixedly connected to one end of the return spring 14. When the toggle block 15 moves upward, it compresses the return spring 14. During reset, the elastic force of the return spring 14 carries the toggle block 15 back to its original position. The other end of the return spring 14 is fixedly connected to the middle of the toggle block 15. The toggle block 15 passes through and slides on the inner wall of the filter frame 12. The filter frame 12 has a slot for the toggle block 15 to move, which allows the toggle block 15 to move vertically along the filter frame 12. The toggle block 15 is inserted into the inner wall of the filter box 11. The filter box 11 has a slot corresponding to the toggle block 15, which allows the toggle block 15 to be inserted and limit the filter frame 12. The L-tube 10 passes through and is fixedly connected to the inner wall of the conveyor box 1.

[0038] Reference Figures 2-4 A bidirectional lead screw 8 is rotatably connected to the inner wall of the conveyor box 1, and a motor 9 is fixedly connected to the inner wall of the conveyor box 1. The connecting pipe 3, the fixed pipe 4, the sleeve 5, and the movable pipe 6 are connected to each other.

[0039] Working principle: When air cooling is required for the film conveyed on the conveyor belt 16, simply drive the fan 2 through an external device. The fan 2 draws in outside air and pressurizes it to send the airflow into the connecting pipe 3. The airflow is accelerated by the tapered groove on the inner wall of the connecting pipe 3, which is wider at the top and narrower at the bottom. When the air enters the narrow area from the wider area, the flow rate increases, forming a high-speed airflow, which enhances the air cooling efficiency. Some of the air will also pass through the fixed pipe 4 and the sleeve 5 to enter the movable pipe 6. The tapered groove on the inner wall of the movable pipe 6 will further increase the air cooling efficiency. When air cooling is required according to the width of the film, the motor 9 can be started to move the slider 7 along the inner wall of the bidirectional lead screw 8. The slider 7 can bring the movable pipe 6 closer together or separate, depending on the width of the film. For large-area air cooling of the film, the motor 9 can be continuously started to move the slider 7 and the movable pipe 6 back and forth, allowing the cold air blown out by the tapered groove of the movable pipe 6 and the connecting pipe 3 to quickly cool the film.

[0040] During use, the device is driven by an external device to operate the fan 13, which delivers hot air from the delivery box 1 into the filter box 11 and filters it through the filter screen on the filter frame 12. The filter screen can further adsorb odors such as chemical gases released during film production. The purified air is discharged through the exhaust pipe to avoid environmental pollution. When the filter screen needs to be replaced, the lever 15 is pushed upward to compress the reset spring 14, so that the lever 15 is released from the slot of the filter box 11. The filter frame 12 is then pulled out for cleaning or replacement. After the operation is completed, the lever 15 is inserted into the filter box 11, and the lever 15 automatically resets and locks under the action of the spring.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
