Description

Technical Field

[0002] In the prior art, the high-efficiency coating machine for aluminized films is generally a vacuum evaporation chamber. After the aluminized film is output from the vacuum evaporation chamber, since the aluminized layer on it has not been completely shaped, it still needs to be cooled before being wound and packaged.

[0003] In the prior art, the aluminized film is generally cooled by natural cooling, air cooling and water cooling. Natural cooling will obviously greatly reduce the processing efficiency of the aluminized film. While directly using air cooling or water cooling, it is easy to cause wrinkles or deformation of the aluminized layer on the aluminized film, and the cooling mechanism needs to be improved. Summary of the Utility Model

The first blowing mechanism is arranged below the arc-shaped groove, and the air outlet of the first blowing mechanism is inclined downward towards the lower end of the pre-cooling roller;

[0007] Drainage ports are respectively arranged on both sides of the bottom of the water cooling tank, and water inlets are respectively arranged at the upper ends of both sides of the water cooling tank.

[0021] Figure 2 is a top view of the cooling mechanism in the present utility model.

Specific Embodiments

[0023] Next, through embodiments and in combination with the drawings, the technical solutions of the present utility model will be further specifically described.

[0024] Combined with Figure 1 and Figure 2 As shown, a high-efficiency coating machine for aluminized film includes a vacuum evaporation chamber and a cooling mechanism;

[0025] The cooling mechanism consists of a frame 1, a pre-cooling roller 2 and a first blowing mechanism 3 arranged below the front end of the frame 1, a turning roller 4 arranged above the front end of the frame 1, a water-cooling tank 5 arranged at the top of the frame 1, and a second blowing mechanism 6;

[0026] A cooling water channel 7 is provided inside the pre-cooling roller 2. Rotary joints are respectively provided at both ends of the pre-cooling roller 2. The two rotary joints are respectively connected to the pump body in the water tank through connecting pipes. An arc-shaped groove 8 is provided below the front end of the frame 1. The rear upper side of the pre-cooling roller 2 is arranged close to the arc-shaped groove 8. The first blowing mechanism 3 is arranged below the arc-shaped groove 8. The air outlet of the first blowing mechanism 3 is inclined downward towards the lower end of the pre-cooling roller 2. The gap between the pre-cooling roller 2 and the arc-shaped groove 8 is small, and the air blown by the first blowing mechanism 3 is blown obliquely downward, so that the air blown by the first blowing mechanism 3 will not be blown upward to cause the aluminized film 9 above to be lifted;

[0027] After the aluminized film 9 is output from the vacuum evaporation chamber, the aluminized layer of the aluminized film 9 is arranged downward and conveyed upward through the pre-cooling roller 2. Under the combined action of the pre-cooling roller 2 and air cooling, the aluminized layer is quickly shaped, preparing for the subsequent water cooling;

[0028] Drain ports 10 are respectively provided on both sides of the bottom of the water-cooling tank 5. Water inlets 11 are respectively provided at the upper ends of both sides of the water-cooling tank 5. The cooling water in the water-cooling tank 5 circulates between the water-cooling tank 5 and the water tank;

[0029] A plurality of pressure rollers 17 are further provided above the water-cooling tank 5. Each pressure roller 17 is arranged close to the bottom of the water-cooling tank 5 to prevent the aluminized film 9 from floating during the water-cooling process;

[0030] A slope 12 is further provided at the rear end of the water-cooling tank 5. The second blowing mechanism 6 is arranged on the frame 1 behind the slope 12. The air outlet of the second blowing mechanism 6 is inclined downward along the slope of the slope 12 to blow the water attached to the aluminized film 9 back into the water tank.

[0031] The working principle of the above structure is as follows: The aluminized film 9 pre-cooled and quickly shaped by the pre-cooling roller 2 and the first blowing mechanism 3 is conveyed to the top of the frame 1 through the turning roller 4 and input into the water-cooling tank 5. Under the action of each pressure roller 17, the aluminized film 9 passes through below the water level in the water-cooling tank 5, and the cooling water in the water-cooling tank 5 circulates continuously to maintain a low temperature. The aluminized film 9 is output along the slope 12 of the water-cooling tank 5. During the process of outputting from the water-cooling tank 5, the second blowing mechanism 6 blows air to blow the water on the back of the aluminized film 9 back into the water tank, and the water attached to the front of the aluminized film 9 flows back into the water tank along the inclined slope. Finally, the aluminized film 9 is dried and then wound and packed to complete the processing.

[0032] The beneficial effects of the above structure are as follows: Before the aluminized film 9 is cooled by water, it first passes through the pre-cooling roller 2 and the first blowing mechanism 3 to quickly shape the aluminized layer of the aluminized film 9, avoiding wrinkles and deformation of the aluminized film 9 in the water cooling tank 5; at the same time, the above cooling mechanism also has the advantages of simple structure and low manufacturing cost, and can be directly docked with the output port of the vacuum evaporation chamber to improve the processing efficiency of the entire coating machine.

[0035] In another embodiment, as Figure 1 shown, steps 14 are respectively provided at the lower ends of the front and rear ends of the frame 1, and the first blowing mechanism 3 is arranged in the step 14 at the front end of the frame 1 to make the overall layout of the frame 1 reasonable.

[0036] In another embodiment, the turning roller 4 and the pressure roller 17 are both hollow roller bodies to reduce their own weights.

[0037] In another embodiment, in combination with Figure 1 and Figure 2 shown, edge guards 15 are respectively provided on both sides of the top of the frame 1.

[0038] In another embodiment, in combination with Figure 1 and Figure 2 shown, a slope 12 is also provided at the front end of the water cooling tank 5 to facilitate the input of the aluminized film 9.

[0039] In another embodiment, in combination with Figure 1 and Figure 2 shown, the front and rear ends of the top of the frame 1 respectively have arc chamfers to avoid cutting the aluminized film 9.

[0040] In another embodiment, in combination with Figure 1 and Figure 2 shown, a mounting bracket 16 is fixed at the rear end of the top of the frame 1, and the second blowing mechanism 6 is fixed on the mounting bracket 16.
