Description

Technical Field

[0001] The utility model relates to the technical field of aluminum-plated film processing, and more specifically, it relates to a vacuum winding aluminum-plating machine for aluminum-plated film processing. Background Art

[0002] The vacuum aluminum coating machine uses the principle of physical vapor deposition to coat aluminum thin films on the surface of various materials. The main components of the vacuum aluminum coating machine include vacuum chamber, exhaust system, aluminum source heating system, material carrier, etc. When working, first put the object to be plated into the vacuum chamber, and then use the exhaust system to evacuate the air in the chamber to make it reach a high vacuum state. Then start the aluminum source heating system to heat and evaporate the aluminum raw material into aluminum vapor. They propagate in the vacuum environment, and some will collide and deposit on the surface of the target object. As the coating gradually thickens, a uniform and compact aluminum film layer will form on the surface of the target object.

[0003] Specifically, the melting point of aluminum is 660.32℃ and the boiling point is 2467℃. Under vacuum conditions, the solid aluminum material is heated by an evaporation boat. When the temperature reaches about 660℃, the aluminum will be converted into liquid and begin to produce aluminum vapor. Although the boiling point of aluminum is as high as 2467℃, the liquid aluminum can be quickly evaporated by heating in the vacuum aluminum plating machine cavity without reaching the boiling point. Because under vacuum conditions, the atmospheric pressure is extremely low, and aluminum materials are more likely to evaporate. The heating temperature is generally controlled between 680-730℃, and the aluminum will fully evaporate to provide the aluminum vapor required for aluminum plating.

[0004] The existing publication number CN220703787U is an aluminum plating machine with a heat recovery function, which includes a feeding mechanism, a preheating mechanism, a coating mechanism, and a winding mechanism arranged in a vacuum chamber, and is characterized in that the coating mechanism includes: an aluminum plating drum, an evaporation boat and a heat recovery unit; the aluminum plating drum is a cylindrical structure, the evaporation boat is located below the aluminum plating drum, and the film pulled by the winding mechanism covers the bottom curved surface of the aluminum plating drum; wherein the heat recovery unit is arranged on both sides below the aluminum plating drum, and the heat recovery includes two relatively arranged recovery bins, the recovery bins are made of metal, and have a cavity inside; the surfaces of the two recovery bins that are close to each other are inclined planes that are inclined toward each other, and the spacing between the inclined planes forms a space for aluminum plating; the recovery bin is provided with a water inlet, a water outlet and a steam outlet, and the water inlet, the water outlet and the steam outlet are all connected to pipes leading out to the outside of the vacuum chamber.

[0005] The aluminizing machine of the above scheme can recover part of the heat generated during the aluminizing process by setting up a recovery bin and heat conducting strips to collect the high-temperature steam generated by the evaporation boat during aluminizing and perform heat exchange to recover heat energy.

[0006] After the aluminum coating is formed, it needs to be rolled up by a winding mechanism. In addition, because the aluminum coating film is continuously transmitted, heated, and rolled up, the aluminum coating film will be offset when it is rolled up again, which will cause wrinkles in the rolled-up aluminum coating film, affecting the subsequent use and storage of the aluminum coating film. Therefore, this application document proposes a new solution to solve the problem of wrinkles and loose connections in the rolled-up aluminum coating film. Utility Model Content

[0007] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a vacuum winding aluminum plating machine for aluminum plating film processing, which can compress the aluminum plating film rolled up by the winding roller while rolling it up, so as to ensure the flatness of the aluminum plating film during the rolling process.

[0008] The above technical purpose of the utility model is achieved through the following technical solutions: a vacuum winding aluminum plating machine for aluminum film processing, including a vacuum chamber and a feeding mechanism, a preheating mechanism, a coating mechanism and a winding mechanism arranged in the vacuum chamber, the winding mechanism includes a winding roller rotatably connected to the vacuum chamber, a clamping mechanism is arranged directly above the winding roller, the clamping mechanism includes an air expansion shaft arranged above the winding roller and an adjustment component for adjusting the distance between the winding roller and the air expansion shaft, the adjustment component includes support plates symmetrically arranged at both ends of the air expansion shaft, a support frame fixedly connected to the support plate, and a drive component arranged between the support frame and the support plate.

[0009] By adopting the above technical scheme, the aluminum-coated film enters the vacuum chamber through the feeding mechanism, and is continuously transmitted in the vacuum chamber through the feeding mechanism and the winding mechanism, and is processed in the vacuum chamber through the preheating mechanism and the coating mechanism. After the processing of the aluminum-coated film is completed, it is rolled up through the winding mechanism, and the winding mechanism rolls up the processed aluminum-coated film through the winding roller outside the vacuum chamber, and then during the winding process of the aluminum-coated film, the driving component on the support frame is used to adjust the position of the support plate, and at the same time, the position of the air expansion shaft and the winding roller is adjusted, and the air expansion shaft is on the winding roller When the aluminum-coated film is rolled up, gas is first introduced to expand the gas expansion shaft and fit closely to the outer wall of the winding roller, so that the aluminum-coated film on the winding roller will fit closely to the outer wall of the winding roller, always maintaining a tight state without deviation and slipping, and then continuously rolled up by the winding roller. After the winding roller is enlarged, the setting height of the gas expansion shaft will be adjusted through the action of the driving component, and the gas expansion shaft and the outer wall of the winding roller are still kept close to the aluminum-coated film, thereby ensuring the tightness of the aluminum-coated film after rolling, and ensuring that the surface of the aluminum-coated film is smooth, so that the quality of the aluminum-coated film output is also improved.

[0010] The utility model is further configured as follows: the driving assembly comprises a telescopic cylinder rotatably connected between the support frame and the support plate.

[0011] By adopting the above technical solution, as the winding roller is continuously wound, the winding roller will push the air shaft. In order to ensure that the air shaft and the surface of the winding roller are tightly fitted and pressed, it is necessary to drive the telescopic cylinder to push the support plate and the air shaft on the support plate, so that the air shaft moves as the winding roller increases, preventing obstruction between the air shaft and the winding roller. The rotational connection of the telescopic cylinder between the support frame and the support plate can prevent the telescopic cylinder from breaking due to rigid extension and contraction, thereby being able to drive the movement of the air shaft more stably.

[0012] The utility model is further configured as follows: both ends of the winding roller are fixedly connected to limiting blocks.

[0013] By adopting the above technical solution, the setting of the limit block can further limit the aluminized film, ensuring that the aluminized film is confined between the limit block, the winding roller and the air expansion shaft, ensuring the stability of the aluminized film during the winding process and preventing slippage and deviation that would cause wrinkles and unevenness in the aluminized film, thereby ensuring the quality of the aluminized film output.

[0014] The utility model is further configured as follows: the limiting block is provided with rounded corners on all four sides.

[0015] By adopting the above technical solution, the limit block will not cause surface damage to the aluminized film when it contacts with the aluminized film, thereby reducing damage to the aluminized film during the winding process and ensuring the quality of the aluminized film winding.

[0016] The utility model is further configured as follows: an outer sleeve of the gas expansion shaft is provided with an anti-slip sleeve.

[0017] By adopting the above technical solution, the anti-slip sleeve can be made of wear-resistant materials such as rubber to increase the friction between the air inflation shaft and the winding roller, thereby preventing the winding roller from slipping and deviating when winding the aluminized film, ensuring that the aluminized film is stably attached to the outer wall of the winding roller, so that the aluminized film remains flat and wrinkle-free after winding, thereby improving the quality of the aluminized film output.

[0018] The utility model is further configured as follows: both ends of the winding roller are provided with limiting sleeves, the limiting sleeves are rotatably connected to the vacuum chamber through a rotating shaft, and the winding roller is clamped in the interior of the limiting sleeves.

[0019] By adopting the above technical solution, the winding roller can be detachably connected to the limit sleeve, which makes it convenient to remove and replace the winding roller after the aluminum-coated film is wound up from the vacuum chamber, thereby facilitating the operation of the staff. At the same time, the aluminum-coated film is wound up by driving the limit sleeve to drive the rotation of the winding roller.

[0020] The utility model is further configured as follows: a limiting rod is fixedly connected to the winding roller, the limiting rod is arranged in a cross shape, a plurality of first threaded holes are opened on the limiting rod, a plurality of second threaded holes corresponding to the first threaded holes are opened in the limiting sleeve, and fixing screws are threadedly connected in the first threaded holes and the second threaded holes.

[0021] By adopting the above technical solution, after the winding roller has rolled up the aluminum-coated film, it needs to be disassembled and replaced with the next winding roller to roll up the aluminum-coated film. The staff can rotate the fixing screw to make the fixing screw rotate out of the first threaded hole and the second threaded hole and disengage the limit rod and the limit sleeve, so that the limit rod of the winding roller can be removed from the limit sleeve, which is convenient for the staff to replace the entire winding roller and also convenient for the maintenance of the winding roller. The cross-shaped part of the winding roller will be more stable when connected to the limit sleeve, and it will be more stable when the limit sleeve is driven to rotate by the motor, which is convenient for the staff to operate.

[0022] The utility model is further configured as follows: the fixing screw is configured in a T-shape.

[0023] By adopting the above technical solution, the fixing thread arranged in a T-shape can more conveniently rotate the fixing thread, preventing the fixing screw from being completely rotated into the first threaded hole and the second threaded hole.

[0024] To sum up, the utility model has the following beneficial effects: under the action of the adjustment component, the air inflation shaft and the winding roller are closely fitted, so that the aluminum-coated film wound by the winding roller can be pressed while being wound, thereby ensuring the flatness of the aluminum-coated film during the winding process, so that wrinkles will not appear on the surface of the aluminum-coated film after winding, affecting subsequent use.

[0032] A vacuum winding aluminum coating machine for aluminum film processing, referring to Figure 1-Figure 2 , including a vacuum chamber 1 and a feeding mechanism, a preheating mechanism, a coating mechanism and a winding mechanism arranged in the vacuum chamber 1, the winding mechanism includes a winding roller 2 rotatably connected to the vacuum chamber 1, a clamping mechanism is arranged directly above the winding roller 2, the clamping mechanism includes an air expansion shaft 3 arranged above the winding roller 2 and an adjustment component for adjusting the distance between the winding roller 2 and the air expansion shaft 3, the adjustment component includes support plates 5 symmetrically arranged at both ends of the air expansion shaft 3, a support frame 4 fixedly connected to the support plate 5 and a driving component arranged between the support frame 4 and the support plate 5, the driving component includes a telescopic cylinder 6 rotatably connected between the support frame 4 and the support plate 5.

[0033] Both ends of the winding roller 2 are fixedly connected to the limiting blocks 10, and the limiting blocks 10 are all provided with rounded corners around them.

[0034] The outer side of the air inflation shaft 3 is covered with an anti-slip sleeve.

[0035] A limiting sleeve 7 is provided at both ends of the winding roller 2. The limiting sleeve 7 is rotatably connected to the vacuum chamber 1 through a rotating shaft. The winding roller 2 is inserted into the inside of the limiting sleeve 7. A limiting rod 9 is fixedly connected to the winding roller 2. The limiting rod 9 is arranged in a cross shape. A plurality of first threaded holes are provided on the limiting rod 9. A plurality of second threaded holes corresponding to the first threaded holes are provided in the limiting sleeve 7. A fixing screw 8 is threadedly connected to the first threaded hole and the second threaded hole. The fixing screw 8 is arranged in a T shape.

[0036] Working principle: the aluminized film enters the vacuum chamber 1 through the feeding mechanism, and is continuously transmitted in the vacuum chamber 1 through the feeding mechanism and the winding mechanism, and is processed in the vacuum chamber 1 through the preheating mechanism and the coating mechanism. After the processing of the aluminized film is completed, it is wound up through the winding mechanism, and the winding mechanism winds up the processed aluminized film through the winding roller 2 outside the vacuum chamber 1. In the process of winding up the aluminized film, the driving component on the support frame 4 is used to adjust the position of the support plate 5, and at the same time adjusts the position of the air expansion shaft 3 and the winding roller 2, and the air expansion shaft 3 is wound on the winding roller 2. While the aluminum film is being plated, gas is first introduced to make the air expansion shaft 3 expand and fit tightly against the outer wall of the winding roller 2, so that the aluminum film on the winding roller 2 will fit tightly against the outer wall of the winding roller 2, always maintaining a tight state without deviation or slipping, and then continuously winding up through the winding roller 2. After the winding roller 2 is enlarged, the setting height of the air expansion shaft 3 will be adjusted through the action of the driving component, and the air expansion shaft 3 and the outer wall of the winding roller 2 are still kept close to the aluminum film, thereby ensuring the tightness of the aluminum film after winding up, and ensuring that the surface of the aluminum film is smooth, so that the quality of the aluminum film output is also improved.

[0037] As the winding roller 2 is continuously wound, the winding roller 2 will push the air shaft 3. In order to ensure that the air shaft 3 is tightly pressed against the surface of the winding roller 2, it is necessary to drive the telescopic cylinder 6 to push the support plate 5 and the air shaft 3 on the support plate 5, so that the air shaft 3 moves as the winding roller 2 increases, preventing obstruction between the air shaft 3 and the winding roller 2. The telescopic cylinder 6 is rotatably connected between the support frame 4 and the support plate 5 to prevent the telescopic cylinder 6 from breaking due to rigid extension and contraction, thereby being able to more stably drive the movement of the air shaft 3.

[0038] The setting of the limit block 10 can further limit the aluminum-coated film, ensuring that the aluminum-coated film is confined between the limit block 10 and the winding roller 2 and the air inflation shaft 3, ensuring the stability of the aluminum-coated film during the winding process and preventing slippage and deviation that would cause wrinkles and unevenness in the aluminum-coated film, thereby ensuring the quality of the aluminum-coated film output. When the limit block 10 contacts the aluminum-coated film, the surface of the aluminum-coated film will not be damaged, thereby reducing damage to the aluminum-coated film during the winding process and ensuring the quality of the aluminum-coated film winding.

[0039] The winding roller 2 can be detachably connected to the limiting sleeve 7, so that the winding roller 2 that has finished winding up the aluminized film can be easily removed from the vacuum chamber 1 for replacement, thereby facilitating the operation of the staff. At the same time, the aluminized film can be wound up by driving the limiting sleeve 7 to drive the winding roller 2 to rotate.

[0040] After winding up the aluminum-coated film, the winding roller 2 needs to be disassembled and replaced with the next winding roller 2 to wind up the aluminum-coated film. The staff can rotate the fixing screw 8 to make the fixing screw 8 turn out from the first threaded hole and the second threaded hole and disengage the limit rod 9 and the limit sleeve 7, so that the limit rod 9 of the winding roller 2 can be removed from the limit sleeve 7, which is convenient for the staff to replace the entire winding roller 2 and also convenient for the maintenance of the winding roller 2. The cross-shaped part of the winding roller 2 will be more stable when connected to the limit sleeve 7, and it will be more stable when the limit sleeve 7 is driven to rotate by the motor, which is convenient for the staff to operate.

[0041] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
