Description

Technical Field

[0001] This invention relates to the field of vacuum aluminum plating machine technology, and more specifically, to a vacuum aluminum plating machine. Background Art

[0002] In existing technologies, the outer shell of a vacuum metallizing machine is formed by joining two shells together to create a sealed environment. This places high demands on the sealing at the joint of the two shells. The existing metallizing machine seals the joint by deforming the sealing strip through the pressure between the shells. Since the metallizing machine requires the constant opening and closing of the two shells for loading and unloading, the frequent opening and closing of the shells can cause the sealing strip to deform or become damaged when the two shells are closed and pressed together. This results in the negative pressure environment inside the sealed space not meeting the standards, affecting the metallization effect of the base film. Therefore, a technical solution is needed to solve the above problems. Summary of the Invention

[0034] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1-3As shown, this embodiment discloses a vacuum aluminum plating machine, including a housing 7, a roller assembly 101, and an aluminum plating evaporator 6. The housing 7 includes a first outer shell 71 and a second outer shell 72. The second outer shell 72 can be close to or away from the first outer shell 71. The first outer shell 71 is fixed. The bottom of the second outer shell 72 is provided with a guide rail. The second outer shell 72 is equipped with a driving device that can drive the second outer shell 72 to slide along the guide rail. When the first outer shell 71 and the second outer shell 72 are open, they can feed and unload the unwinding roller 1 and the winding roller 2 on the roller assembly 101. The roller assembly 101 and the aluminum plating evaporator 6 are fixedly installed on the first outer shell 71. The first outer shell 71 and the second outer shell 72 can be closed to form a sealed space. After the first outer shell 71 and the second outer shell 72 are closed, a vacuum pump is used to evacuate the sealed space to provide an aluminum plating environment for the aluminum plating evaporator 6. The roller assembly 101 and the aluminum plating evaporator 6 are located in the sealed space.

[0036] The first outer shell 71 includes a first outer edge plate 711 and a first inner edge plate 712, with a slot 713 formed between the first outer edge plate 711 and the first inner edge plate 712. A portion of the second outer shell 72 can be inserted into the slot 713. The second outer shell 72 is provided with a second outer edge plate 721 and a second inner edge plate 722. A sealing strip 8 is installed between the second outer edge plate 721 and the second inner edge plate 722. When the first outer shell 71 and the second outer shell 72 are closed, the second outer edge plate 721 is located inside the first outer edge plate 711. On the side, the second inner edge plate 722 is located inside the first inner edge plate 712. Sealing strips are installed at the ends of the first outer edge plate 711, the second outer edge plate 721, the first inner edge plate 712, and the second inner edge plate 722. Two labyrinth-shaped sealing structures are formed between the first outer edge plate 711, the second outer edge plate 721, the first inner edge plate 712, and the second inner edge plate 722. At the same time, the sealing strips installed at the ends can play a role in resisting deformation and sealing at the ends, forming two seals inside and out, resulting in a better sealing effect.

[0037] The second outer shell 72 is fitted with a sealing strip 8, which is installed around the end face of the second outer shell 72 facing the first outer shell 71. The sealing strip 8 includes a deformable part 81 and a connecting part 82. The second outer shell 72 is provided with a connecting seat 723. The deformable part 81 has an opening facing the first outer shell 71. The first outer shell 71 has an adsorption surface 714 facing the deformable part 81. The adsorption surface 714 is located on the end face of the slot 713 facing the sealing strip 8. When the first outer shell 71 and the second outer shell 72 are closed, the adsorption surface 714 closes the opening of the deformable part 81. The deformable part 81 has a deformable cavity 812 inside, and the cross-section of the deformable part 81 is semi-circular. 72 is provided with a through groove 724, which connects to the sealed space. The connecting part 82 is provided with a through hole 821, which connects the through groove 724 and the deformation cavity 812. The deformation cavity 812 connects to the sealed space. When the sealed space is evacuated by a vacuum pump, a negative pressure environment is also formed in the deformation cavity 812, which can tightly adsorb the deformation part 81 onto the adsorption surface 714, thus achieving a good sealing effect. The stronger the internal negative pressure, the stronger the suction between the deformation part 81 and the adsorption surface 714, and the better the sealing effect. At the same time, since the deformation part 81 is not sealed by compression deformation, it will not be subjected to frequent compression, which will cause damage and aging.

[0038] More preferably, the adsorption surface 714 is an arc surface, and the center of the adsorption surface 714 protrudes towards the deformation part 81. The deformation part 81 is provided with a plate 811, which is located on both sides of the opening of the deformation cavity 812. The end face of the plate 811 facing the adsorption surface 714 is a corresponding arc surface. The arc-shaped adsorption surface 714 can better adsorb with the opening of the deformation part 81. The cooperation of the plate 811 can increase the contact area between the opening of the deformation part 81 and the adsorption surface 714, making the adsorption more stable.

[0039] like Figure 3 As shown, the outer wall of the first housing 71 is provided with multiple triggering devices 73, and the outer wall of the second housing 72 is provided with multiple inserts 74 corresponding to the triggering devices 73. The triggering device 73 includes two rollers 731 that can move closer or further apart. A trigger switch 732 is provided on the outside of the rollers 731. The inserts 74 are arrow-shaped and include a first inclined surface 741 and a second inclined surface 743. An endpoint 742 is provided between the first inclined surface 741 and the second inclined surface 743. Part of the insert 74 can be inserted between the two rollers 731. When the rollers 731 reach the endpoint 742, they contact the trigger switch 732. At this time, the plate 811 is exactly attached to the adsorption surface 714. When all the trigger switches 732 are triggered, the vacuum pump is automatically turned on to draw a vacuum. When the rollers 731 are located on the second inclined surface 743, the first housing 71 and the second housing 72 are completely closed. The deformation part 81 undergoes slight pressure deformation, allowing the opening of the deformation part 81 to better adsorb the adsorption surface 714.

[0040] like Figures 4-9As shown, the roller assembly 101 includes an unwinding roller 1, a take-up roller 2, a guide assembly 3, a tensioning assembly 4, and an aluminizing roller 5. It also includes several other rollers for tensioning and rollers for flattening. The base film is unwound by the unwinding roller 1, aluminized by the aluminizing roller 5, and then wound up by the take-up roller 2. The take-up roller 2 is located above the unwinding roller 1. The guide assembly 3 is located between the unwinding roller 1 and the take-up roller 2. There are two guide assemblies 3, which are located at the two ends of the unwinding roller 1 and the take-up roller 2, respectively. The guide assembly 3 includes a first slide rail 31 and a first sliding assembly 32. The first slide rail 31 extends along the axis connecting line of the take-up roller 2 and the unwinding roller 1. The first slide rail 31 extends in a straight line, that is, it extends in a straight line between the axes of the take-up roller 2 and the unwinding roller 1. The first sliding assembly 32 can slide along the first slide rail 31, so that the first sliding assembly 32 can slide radially along the take-up roller 2 and the unwinding roller 1.

[0041] The first sliding assembly 32 includes a bracket 321 and a first support assembly 322. The bracket 321 is slidably connected to the first slide rail 31 and can slide along the first slide rail 31. The first support assembly 322 is located at the lower end of the bracket 321 and includes two support rollers 3222. The support rollers 3222 abut against the outer wall of the unwinding roller 1. The two support rollers 3222 are arranged in parallel, and the axial direction of the support rollers 3222 is parallel to the axial direction of the unwinding roller 1. The outer walls of the two support rollers 3222 are tangential and abut against the outer wall of the unwinding roller 1. The abutting of the two support rollers 3222 can better support the first support assembly 322 and the unwinding roller 1. The support rollers 3222 are located at the end of the unwinding roller 1. The edge of the film roll on the unwinding roller 1 is subjected to pressure, but it will not affect the middle of the film roll. The support rollers 3222 can be made of cork to prevent abrasion of the bottom film. As the diameter of the unwinding roller 1 gradually decreases, the first sliding assembly 32 can descend.

[0042] The first support assembly 322 includes a housing 3221, which is fixedly connected to the bracket 321. The support roller 3222 includes a shaft 32221 and a roller 32222. The roller 32222 is rotatably mounted on the shaft 32221, and the shaft 32221 is slidably mounted on the housing 3221. The housing 3221 is provided with a first guide rod 32211, which extends away from the support roller 3222. The shaft 32221 passes through the side wall of the housing 3221, and one end of the shaft 32221 is slidably connected to the first guide rod 32211. The first guide rod 32211 passes through the shaft 32221, and the shaft 32221 is locked by bolts, so that the support roller 3222 can be telescopically adjusted within the range of the unwinding roller 1 to adapt to different lengths of film rolls.

[0043] The first sliding assembly 32 includes a second support assembly 323. The bracket 321 includes a top plate 3211. The second support assembly 323 includes a first support assembly 322, a second guide rod 3231, and a spring 3233. The support roller 3222 of the first support assembly 322 abuts against the outer wall of the take-up roller 2. The second guide rod 3231 passes through the top plate 3211 and is slidably connected to the top plate 3211. The spring 3233 is installed on the second guide rod 3231 and is located in the second support assembly. Between the first support component 322 and the top plate 3211 of the second support component 323, the first support component 322 inside the second support component 323 can always hold the take-up roller 2 by the action of the spring 3233. The guide component 3 is supported by the first support components 322 at both ends, so that the first sliding component 32 moves more stably on the first slide rail 31. The reaction force of the spring 3233 and the gravity of the first sliding component 32 can keep the first support component 322 located below always against the outer wall of the film roll, making the support structure more stable.

[0044] The bracket 321 includes a guide plate 3212, and a guide block 3232 is installed at the lower end of the second guide rod 3231. The guide block 3232 is slidably connected to the guide plate 3212. The slidable connection between the guide plate 3212 and the guide block 3232 can make the movement support of the second guide rod 3231 more stable.

[0045] More preferably, the outer wall of the support roller 3222 is provided with threads, and the inclined direction of the threads is towards the unwinding direction of the unwinding roller 1 and the direction close to the first slide rail 31. The support roller 3222 can unfold the two ends of the film roll while resisting the unwinding roller 1 or the take-up roller 2 as they rotate, which can prevent wrinkles from appearing on the edges during winding.

[0046] Two tensioning components 4 are symmetrically arranged. The tensioning component 4 includes a second slide rail 41 and a second sliding component 42. The tensioning component 4 is located on one side of the take-up roller 2. The second sliding component 42 can slide along the second slide rail 41. The second sliding component 42 includes a sliding frame 421, a tensioning roller 422, and a flattening roller 423. The sliding frame 421 is slidably connected to the second slide rail 41. The two ends of the tensioning roller 422 are rotatably connected to the two sliding frames 421. The two ends of the flattening roller 423 are rotatably connected to the two sliding frames 421. The bottom film first passes through the flattening roller 423 and then through the tensioning roller 422. The flattening roller 423 can flatten the conveyed bottom film. After being tensioned by the tensioning roller 422, it is wound up by the take-up roller 2.

[0047] The first sliding assembly 32 includes a guide tube 324, and the second sliding assembly 42 includes a third guide rod 424. The third guide rod 424 is slidably connected to the guide tube 324 and is at least partially located inside the guide tube 324. A channel 3241 is formed inside the guide tube 324, and the third guide rod 424 can move along the channel 3241. A mounting seat 3242 is installed on the inner wall of the end of the guide tube 324. The mounting seat 3242 is provided with a plurality of first support wheels 3243, and the first support wheels 3243 abut against the first... The outer wall of the three guide rods 424 has multiple second support wheels 4241 installed at the end of the third guide rod 424. The second support wheels 4241 abut against the inner wall of the guide tube 324. The guide tube 324 and the third guide rod 424 are mutually supported by the first support wheel 3243 and the second support wheel 4241, making the sliding extension and retraction of the guide tube 324 and the third guide rod 424 more stable. The bracket 321 and the guide tube 324 are connected by the support frame 325, making the structure of the guide tube 324 more stable.

[0048] More preferably, the second slide rail 41 is inclined, with the end of the second slide rail 41 away from the take-up roller 2 being higher than the end near the take-up roller 2. Since the end of the second slide rail 41 near the take-up roller 2 is lower, the second sliding component 42 can be reset when the second state is restored to the first state by the action of gravity.

[0049] The first slide rail 31, the second slide rail 41, the guide tube 324, and the third guide rod 424 form a triangular structure. When the first sliding component 32 gradually moves away from the take-up roller 2, the second sliding component 42 also moves away from the take-up roller 2 at the same time. The support roller 3222 of the first sliding component 32 abuts against the unwinding roller 1. As the diameter of the unwinding roller 1 gradually decreases, the tensioning roller 422 gradually moves away from the take-up roller 2. The bottom film passes sequentially through the unwinding roller 1, the aluminizing roller 5, the tensioning roller 422, the flattening roller 423, and the take-up roller 2. The tensioning component 4 includes a first state and a second state. In the first state, the diameter of the unwinding roller 1 is the largest, the diameter of the winding roller 2 is the smallest, the first sliding component 32 is at the highest position, and the center distance between the tension roller 422 and the winding roller 2 is the closest. In the second state, the diameter of the unwinding roller 1 is the smallest, the diameter of the winding roller 2 is the largest, the first sliding component 32 is at the lowest position, and the center distance between the tension roller 422 and the winding roller 2 is the farthest. During the process from the first state to the second state, the distance between the outer wall of the tension roller 422 and the winding roller 2 remains unchanged, so that the tension force generated by the tension roller 422 on the winding roller 2 also remains stable.
