[0055] Such as Figure 1 、 Figure 2As shown, the present utility model provides an aluminizing device, which includes a vacuum chamber 100. A winding module is arranged inside the vacuum chamber 100. The winding module includes an unwinding roller 11 and a winding roller 12. The unwinding roller 11 and the winding roller 12 are located in the same height region. There is a spaced space between the unwinding roller 11 and the winding roller 12. A front main roller 13 is arranged below the unwinding roller 11 and the winding roller 12. A film roll is installed on the unwinding roller 11. The film is released from the unwinding roller 11, passes through the front main roller 13 below the unwinding roller 11, and is wound by the winding roller 12. A blowing port 39 (not shown in the figure) for blowing air downward is arranged above the front main roller 13, in the spaced space and / or above the spaced space. By arranging each roller and setting the blowing port 39 above the main roller for coating, the present utility model allows gas to fill the gap between the film and the roller, which helps to make the contact between the film and the roller more flat and is beneficial to solving the problem of aluminizing void lines. The unwinding roller 11 and the winding roller 12 of the present utility model are located at the same height or in the same height region, and there may be a certain height difference between their positions, and this height difference does not exceed 10 cm. Further, in the aluminizing device provided by the present utility model, the gas output from the blowing port 39 is an inert gas. The blown gas is an inert gas such as nitrogen. The blown nitrogen can help the film to fit more closely with the main roller and is beneficial to reducing aluminizing void lines. The blowing port 39 can be supplied with gas by an external air compressor.
[0056] Further, in the aluminizing device provided by the present utility model, a rear main roller 14 is also arranged below the unwinding roller 11 and the winding roller 12. The film is released from the unwinding roller 11, passes through the front main roller 13 and the rear main roller 14 below the unwinding roller 11 in sequence, and then is wound by the winding roller 12. The front main roller 13 is located below the unwinding roller 11, and the rear roller is located below the winding roller 12. A blowing port 39 for blowing air downward is arranged above the front main roller 13, above the rear main roller 14, in the spaced space and / or above the spaced space. Further, in the aluminizing device provided by the present utility model, a front roller group 15 is arranged on the film running path between the unwinding roller 11 and the front main roller 13. The front roller group 15 is composed of multiple guide rollers.
[0057] Further, for the aluminizing equipment provided by the present utility model, a front bending roller 16 is arranged on the film passing path between the front roller group 15 and the front main roller 13. On the one hand, the front bending roller 16 can flatten the film to facilitate aluminizing, and on the other hand, it can also provide a certain tension to the film, so that there is a greater adhesion force between the film and the front main roller 13 during aluminizing. Preferably, the surface roughness of the front bending roller 16 is greater than that of other passing rollers, which is beneficial to ensuring the adhesion force between the film and the main roller while preventing the film from being scratched when moving over the roller. The front main roller 13 is a cooling roller and can be used to cool the film. A crucible can be arranged below the front main roller 13. Generally, there are multiple crucibles, which are arranged in two columns.
[0058] Further, for the aluminizing equipment provided by the present utility model, a front rubber roller 17 and a rear bending roller 19 are arranged on the film passing path between the front main roller 13 and the rear main roller 14. The front rubber roller 17 can also be a roller with roughness, which can prevent the film from slipping after aluminizing and can also increase the wrap angle between the film and the front main roller 13. Further, for the aluminizing equipment provided by the present utility model, a swing roller 18 is also arranged on the film passing path between the front rubber roller 17 and the rear bending roller 19. The swing roller 18 can play a role in maintaining a constant tension between the two main rollers. Further, for the aluminizing equipment provided by the present utility model, a rear rubber roller 20 is also arranged on the film passing path between the rear main roller 14 and the winding roller 12. The rear main roller 14 is a cooling roller and can also be used to cool the film. A crucible can also be arranged below the rear main roller 14 for evaporating aluminizing. The roughness of the rear rubber roller 20 can also be greater than that of other passing rollers, which helps the film not to slip and makes the film fit more closely with the main roller.
[0059] Further, for the aluminizing equipment provided by the present utility model, a tension roller 21 and a rear roller group 22 are also arranged on the film passing path between the rear rubber roller 20 and the winding roller 12. Above the front rubber roller 17 and the tension roller 21, a film surface temperature sensor (not shown in the figure) is arranged. The film surface temperature sensor is mainly arranged above the rear main roller 14 and can be used to detect the temperature of the film surface in real time after aluminizing on the main roller. The rear roller group 22 is composed of multiple passing rollers. The tension roller 21 mainly controls the tension of the film. The film coming out of the tension roller 21 passes through multiple passing rollers and finally reaches the winding roller 12. Further, for the aluminizing equipment provided by the present utility model, the blowing port is arranged to blow air obliquely from top to bottom, preferably blowing at an inclination angle with respect to the plane where the two main rollers are located, so that the film fits better with the two main rollers, such as a blowing angle of 45° to 90°. A high-speed camera can be arranged at the top of the vacuum chamber 100 of the present utility model to detect the film surface condition in real time.
[0060] Preferably, an aluminizing device provided by the utility model comprises a vacuum chamber 100, an upper vacuum pumping group 31 and a lower vacuum pumping group 32.

A plurality of parallel-connected molecular pumps 35 and a plurality of parallel-connected diffusion pumps 36 are further arranged between the Roots pump 34 of the upper vacuum pumping group 31 and the vacuum chamber 100.

Moreover, the two groups of vacuum pumping groups are separately arranged, which is beneficial to reasonably allocate space and can achieve the effect of saving space.
[0061] The number of vacuum pumps in the upper vacuum pumping group 31 is more than that in the lower vacuum pumping group, which can exhaust the air in the winding module as much as possible, facilitating the evacuation of the air inside the film and ensuring the coating effect and efficiency. Further, for the aluminizing equipment provided by the present utility model, the upper vacuum pumping group 31 further includes a holding pump 37, and the holding pump 37 is connected between the pipeline of the Roots pump 34 and multiple parallel molecular pumps 35 and multiple parallel diffusion pumps 36.

Further, for the aluminizing equipment provided by the present utility model, in the upper vacuum group, a switching valve 38 is provided between the Roots pump 34 and multiple parallel molecular pumps 35 and multiple parallel diffusion pumps 36. Further, for the aluminizing equipment provided by the present utility model, in the upper vacuum group, switching valves 38 are provided on both the front and rear pipelines of the molecular pump 35, and switching valves 38 are provided on both the front and rear pipelines of the diffusion pump 36. The lower vacuum pumping group 32 includes a mechanical pump 33 and four Roots pumps 34. The mechanical pump 33 is connected on the outside and then respectively connected to two Roots pumps 34, and finally the two Roots pumps 34 are connected in series, and the two Roots pumps 34 are finally connected to the vacuum chamber 100. The mechanical pump 33 is started first, and after reaching an appropriate vacuum degree, the Roots pumps 34 are started in sequence. The multiple Roots pumps 34 are beneficial to pumping the vacuum near the crucible at the lower part of the vacuum chamber 100 to an appropriate value.
[0062] Further, for the aluminizing equipment provided by the present utility model, in the lower vacuum group, there are two Roots pumps 34. The mechanical pump 33 is connected in series with the two Roots pumps 34 and then communicates with the lower part of the vacuum chamber 100.

The upper vacuum pumping group 31 includes one mechanical pump 33, two Roots pumps 34, two holding pumps 37, five diffusion pumps 36, and four molecular pumps 35. One mechanical pump 33 and two Roots pumps 34 are connected in series, and five diffusion pumps 36 and four molecular pumps 35 are connected in series. The parallel connection is mainly because the subsequent pump bodies need to reach a certain vacuum degree to be started, and the parallel connection of the previous pump bodies is to pump vacuum first to make the vacuum reach the working range of the subsequent pump bodies. The series connection is mainly to better exert the effects of each pump body and jointly reach the desired vacuum degree. Through the above settings, the vacuum chamber 100 can reach the appropriate value more quickly, which is beneficial to improving the efficiency.
