Description

Technical Field

[0001] This utility model relates to the field of plastic film cooling technology, and in particular to a novel air-packing device used in WH blown film machines. Background Technology

[0002] The WH blown film machine plays a key role in the production of plastic film. It mainly uses an extrusion device to heat and melt plastic granules and then extrude them to form tubular film bubbles. In order to facilitate the cooling of the plastic film produced by the blown film machine during this process, a new type of air pack device is needed on the WH blown film machine.

[0003] A search revealed Chinese patent publication number CN221775255U, which discloses a cooling device for a plastic film blowing machine, comprising a main body of the device, with a first mounting frame and a second mounting frame respectively installed on both sides of the top of the main body, and a cooling pool installed at the center of the interior of the main body. This invention, by incorporating an air distribution system, a recovery tank, an air compressor, fan-shaped nozzles, and an air inlet, achieves the cleaning of water on the surface of a plastic film. The operation of the air compressor delivers high-pressure gas into the air distribution system, and the distribution of the fan-shaped nozzles forms a plane of airflow that blows onto the surface of the plastic film. The two air distribution systems are arranged in a figure-eight pattern, which blows away the water on the surface of the plastic film. The water collects and flows downwards, dripping into the recovery tank and flowing back into the cooling pool. At the same time, the airflow accelerates the evaporation of moisture, keeping the surface of the plastic film dry and preventing water residue. However, in actual use, the fan blades are in a fixed position, and when agitating the cooling water, they can only create a relatively fixed pattern of disturbance in the local water body, which can easily lead to local water circulation. Furthermore, the fixed position of the fan cannot flexibly adjust the blowing angle and range according to the shape of the material and the actual heat dissipation requirements, which can easily create dead zones in certain parts of the material, thus reducing the reliability of the device. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a novel air-packing device for use on a WH blown film machine, aiming to improve the problem that the fixed design of the blowing and agitation range of the novel air-packing device on the existing WH blown film machine easily leads to dead zones in heat dissipation and cooling.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel air-packing device applied to a WH blown film machine, comprising a base, an outer frame fixedly connected to the top of the base, a first rotating wheel rotatably connected to the left and right sides of the bottom of the inner wall of the base, a belt provided on the outer side of the first rotating wheel, a first motor fixedly connected to the middle of the inner wall of the base, a second rotating wheel fixedly connected to the output end of the first motor, the second rotating wheel being connected to the first rotating wheel via the belt, a connecting rod fixedly connected to the top of the first rotating wheel, a slide rod slidably connected to the inner side of the connecting rod, a rack rotatably connected to the outer side of the slide rod, a second motor fixedly connected to the top of the inner wall of the base, a gear fixedly connected to the output end of the second motor, the gear meshing with the rack, a fan blade fixedly connected to the top of the slide rod penetrating the base, rotating rollers rotatably connected to the left and right sides of the inner wall of the outer frame, and an adjustment mechanism provided on the inner side of the outer frame.

[0006] The above technical solution involves first placing the film on top of the outer frame and driving it with the rotating roller. Then, water is injected to cool the film. A motor is started to drive the rotating wheel, which in turn drives another rotating wheel and connecting rod to rotate via belt drive. This drives the slide bar and fan blades to stir the water flow and dissipate heat. Another motor is started to drive the gear, which moves the rack through meshing transmission. The slide bar is then pulled to adjust the position of the fan blades, allowing the fan blades to be exposed above the water surface for air cooling. This improves the flow and circulation performance of water and air.

[0007] As a further description of the above technical solution:

[0008] The adjustment mechanism includes a water tank, which is fixedly connected to the left side of the inner wall of the outer frame. The right side of the water tank is connected to the outer frame. A float plate is slidably connected to the bottom left side of the inner wall of the outer frame. A threaded rod is rotatably connected to the bottom right side of the inner wall of the outer frame. A first bevel gear is fixedly connected to the top of the threaded rod. A second bevel gear is rotatably connected to the right side of the inner wall of the outer frame. The second bevel gear meshes with the first bevel gear. A positioning frame is threaded to the outer side of the threaded rod. The top of the positioning frame passes through the outer frame and is rotatably connected to a pressure roller.

[0009] Through the above technical solution, rotating the bevel gear drives another bevel gear and the threaded rod to rotate through meshing transmission. The threaded connection moves the positioning frame, thereby adjusting the pressure roller to drive and fix the film. At the same time, relying on the buoyancy of the float plate, the hole on the left side of the outer frame is opened when the water level drops, and the water in the water tank is discharged to achieve automatic water replenishment, which facilitates film fixation and automatic water replenishment.

[0010] As a further description of the above technical solution:

[0011] The base has positioning blocks fixedly connected to all four sides of the bottom of its outer wall, and positioning holes are provided on the outer side of the positioning blocks.

[0012] The above technical solution facilitates the installation and fixation of the device.

[0013] As a further description of the above technical solution:

[0014] The base has brackets fixedly connected to the top of its outer wall around all four sides, and the top of the brackets is fixedly connected to the outer frame.

[0015] The above technical solution can improve the firmness of the fixation between the base and the outer frame.

[0016] As a further description of the above technical solution:

[0017] Handles are fixedly connected to all four sides of the outer wall of the outer frame, and protective sleeves are fixedly connected to the outside of the handles.

[0018] The above technical solution enables the device to be held and moved using a handle.

[0019] As a further description of the above technical solution:

[0020] A controller is fixedly connected to the middle of the front end of the outer frame, and the controller is electrically connected to the first motor and the second motor respectively.

[0021] The above technical solution enables the controller to control the movement of the first motor and the second motor respectively.

[0022] As a further description of the above technical solution:

[0023] The inner side of the outer frame is provided with a groove, and a filter screen is fixedly connected to the inner side of the groove.

[0024] The above technical solution can protect the membrane through the filter screen and reduce the cooling effect of impurities on the cooling water.

[0025] As a further description of the above technical solution:

[0026] A knob is fixedly connected to the right side of the outer frame, and the outer side of the knob passes through the outer frame and is fixedly connected to the second bevel gear.

[0027] The above technical solution enables the second bevel gear to rotate via a knob.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, by placing the film on the top of the outer frame and driving it with the rotating roller, water is injected to cool the film. The motor is started to drive the rotating wheel, which in turn drives another rotating wheel and connecting rod to rotate via a belt. This drives the sliding rod and fan blades to stir water and dissipate heat. Another motor is started to drive the gear, which moves the rack through meshing transmission. The sliding rod is pulled to adjust the position of the fan blades, and the fan blades are exposed above the water surface for air cooling. This improves the circulation of water and air, thereby enhancing the reliability of the device.

[0030] 2. In this utility model, by rotating the bevel gear, another bevel gear and the threaded rod are driven to rotate through meshing transmission. The positioning frame is moved through the threaded connection, and the pressure roller is adjusted to drive and fix the film. At the same time, by using the buoyancy of the float plate, the hole on the left side of the outer frame is opened when the water level drops, and the water in the water tank is discharged, realizing automatic water replenishment of the device. This facilitates the fixing of the film and enables automatic water replenishment, thereby improving the convenience of the device. Attached Figure Description

The controller 16 is electrically connected to the first motor 4 and the second motor 8 respectively, and can control the start and operation of the first motor 4 and the second motor 8 through the controller 16. A groove 20 is opened on the inner side of the outer frame 3. A filter screen 21 is fixedly connected to the inner side of the groove 20, which can reduce the pollution of the cooling water and prevent the membrane from being scratched by the fan blade 12.

[0047] Working principle: Before using the device, first place the film to be cooled along the top of the outer frame 3 and drive the middle part of it with the rotating roller 22. Then, water is injected into the outer frame 3 to cool the film. Then, the first motor 4 is started to drive the second rotating wheel 23 to rotate, which drives the first rotating wheel 5 and its connecting rod 9 to rotate through the belt 6, which drives the slide rod 11 and its fan blades 12 to rotate, stirring the water flow so that it can contact the film for heat dissipation. At the same time, the second motor 8 is started to drive the gear 7 to rotate, which drives the rack 10 to move through meshing transmission, pulling the slide rod 11 to move along the connecting rod 9, adjusting the position of the fan blades 12 on both sides. When the fan blades 12 are exposed above the water surface, they can drive the airflow to cool the film, which can improve the circulation and uniformity of water flow and airflow.
