Description

Technical Field

[0001] This utility model relates to the field of vacuum coating machine technology, specifically a double-layer gas filling tube device for a vacuum coating machine. Background Technology

[0002] A double-layer gas filling tube is used in the coating process where the gas introduced can chemically react with the target material or evaporation material to generate a specific compound film. A double-layer gas filling tube device is required when filling the vacuum coating machine with gas.

[0003] A search revealed that existing patent [CN221440843U] discloses a double-layer gas filling pipe device for a vacuum coating machine, including a coating chamber. The coating chamber includes an upper plate, and a side plate is fixedly connected to the lower edge of the upper plate. A lower plate is fixedly connected to the lower ends of the side plates. A connecting seat is welded to the inside of the upper plate. This invention employs an inner and outer gas outlet pipe. After the gas enters the inner pipe, the opening size gradually increases from top to bottom, and the spacing between the openings is relatively large, ensuring uniform gas output from each outlet. The gas discharged from the inner pipe diffuses within the outer pipe, achieving sufficient diffusion before being discharged. Because the outer pipe has uniform opening size and a smaller spacing, it better ensures uniform gas distribution throughout the coating chamber. This double-layer gas filling pipe device solves the problem of decreasing gas volume from top to bottom within the coating chamber, leading to significant differences in the gas-to-raw material ratio at different locations.

[0004] While the aforementioned utility model patent solves the problem of decreasing gas volume from top to bottom inside the coating chamber, leading to significant differences in the gas-to-raw material ratio at different locations, it lacks the function of scraping and cleaning the film layer attached to the double-layer inflatable tube body. During use, the double-layer inflatable tube body is inside the coating machine. During coating, a film may be coated onto the double-layer inflatable tube body. If this film layer cannot be scraped and cleaned, it will block the air outlet on the double-layer inflatable tube body, preventing gas from being injected. This reduces the practicality of the device. Furthermore, it lacks the function of easily installing and fixing the inflatable tube. During use, installing and fixing the inflatable tube to the coating machine body is cumbersome, requiring professional personnel or a considerable amount of time. This results in poor installation convenience and low practicality of the device. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-layer air-inflating pipe device for a vacuum coating machine, comprising a coating machine body, wherein a scraping and cleaning mechanism is provided inside the coating machine body, the scraping and cleaning mechanism includes a fixing block, the fixing block is fixedly connected inside the coating machine body, a rack is fixedly connected to one side of the fixing block, a slide rail is fixedly connected inside the coating machine body, a motor bracket is slidably connected to the outer wall of the slide rail, a motor is fixedly connected to one side of the motor bracket, the output shaft of the motor is fixedly connected to a motor shaft through a coupling, a gear is fixedly connected to one end of the motor shaft, the gear meshes with the rack, a connecting rod is fixedly connected to one end of the motor bracket, a scraper ring is fixedly connected to one side of the connecting rod, and the double-layer air-inflating pipe body is attached to the inner wall of the scraper ring.

[0007] As a preferred technical solution, the motor bracket has a through hole inside, the shape and size of which match the shape and size of the slide rail, and the motor bracket is slidably connected to the slide rail through the through hole.

[0008] As a preferred technical solution, a door panel is hinged to one side of the coating machine body, and a handle is fixedly connected to one side of the door panel.

The sealing ring is used to cooperate with the door panel to form a seal, and a double-layer air inflator body is movably connected to the top of the coating machine body.

[0010] As a preferred technical solution, the outer wall of the double-layer inflatable tube body is provided with an installation and fixing mechanism, the installation and fixing mechanism includes an installation plate, and the installation plate is fixedly connected to the outer wall of the double-layer inflatable tube body.

[0011] As a preferred technical solution, threaded holes are provided inside the mounting plate and on the top of the coating machine body, and bolts are threaded onto the inner wall of the threaded holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of a scraping and cleaning mechanism, can achieve the function of scraping and cleaning the film layer on the double-layer air tube body. During use, the motor is started to drive the scraper ring to scrape and clean the film layer attached to the double-layer air tube body. During the movement of the scraper ring, the sliding of the motor bracket on the slide rail can make the scraper ring move more smoothly and evenly. This can avoid the situation where the film layer on the double-layer air tube body cannot be scraped and cleaned, which would block the air outlet on the double-layer air tube body and prevent gas from being inflated. This ensures the practicality of the air tube.

[0014] 2. The present invention, through the setting of the installation and fixing mechanism, can facilitate the installation and fixing of the air tube onto the coating machine body. During use, the mounting plate is fixed onto the coating machine body by the cooperation of bolts and threaded holes. This avoids the situation where the process of installing and fixing the air tube onto the coating machine body is cumbersome, which would require professional personnel or a long time to install and fix the air tube, thus ensuring the ease of installation of the device.

[0024] When the device is needed for inflation, the double-layer inflation tube body 7 is first installed into the coating machine body 1. The double-layer inflation tube body 7 is fixed to the coating machine body 1 by the installation and fixing mechanism 3. Then, the door panel 4 is opened by the handle 5. The sealing ring 6 ensures that there is no air leakage inside the coating machine body 1. Then, the substrate to be coated is placed into the coating machine body 1. Then, the top of the double-layer inflation tube body 7 is connected to the pipe, and the gas is evenly released into the interior of the coating machine body 1 through the double-layer inflation tube body 7. This allows the injected gas to mix with the evaporating material and generate a specific compound film. During the formation of the film, a certain film may form on the outer wall of the double-layer inflation tube body 7. The film may block the inflation holes on the double-layer inflation tube body 7. At this time, the film on the double-layer inflation tube body 7 needs to be scraped and cleaned by the scraping and cleaning mechanism 2, thereby completing the work.

[0025] like Figure 2 and Figure 4 As shown, the coating machine body 1 is equipped with a scraping and cleaning mechanism 2. The scraping and cleaning mechanism 2 includes a fixing block 201. The fixing block 201 is fixedly connected inside the coating machine body 1. A rack 202 is fixedly connected to one side of the fixing block 201. A slide rail 203 is fixedly connected inside the coating machine body 1. A motor bracket 204 is slidably connected to the outer wall of the slide rail 203. A motor 205 is fixedly connected to one side of the motor bracket 204. The output shaft of the motor 205 is fixedly connected to a motor shaft through a coupling. 206. A gear 207 is fixedly connected to one end of the motor shaft 206. The gear 207 meshes with the rack 202. A connecting rod 208 is fixedly connected to one end of the motor bracket 204. A scraper ring 209 is fixedly connected to one side of the connecting rod 208. A double-layer air tube body 7 is attached to the inner wall of the scraper ring 209. A through hole is opened inside the motor bracket 204. The shape and size of the through hole match the shape and size of the slide rail 203. The motor bracket 204 is slidably connected to the slide rail 203 through the through hole.

[0026] During the formation of the film layer, a certain film layer may form on the outer wall of the double-layer inflatable tube body 7. This film layer may block the inflation holes on the double-layer inflatable tube body 7. At this time, it is necessary to scrape and clean the film layer on the double-layer inflatable tube body 7. Then, the motor 205 is started, which drives the motor shaft 206 to rotate. The motor shaft 206 drives the gear 207 to rotate. The gear 207 drives the motor shaft 206 to move through the rack 202 on the fixed block 201. The motor shaft 206 drives the motor bracket 204 to move through the motor 205. The motor bracket 204 drives the connecting rod 208 to move. During the movement of the connecting rod 208, the sliding of the motor bracket 204 in the slide rail 203 makes the movement of the connecting rod 208 more stable and smooth. The connecting rod 208 drives the scraper ring 209 to move, so that the scraper ring 209 scrapes and cleans the film layer formed on the outer wall of the double-layer inflatable tube body 7, thereby completing the scraping and cleaning work.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the outer wall of the double-layer inflatable tube body 7 is provided with an installation and fixing mechanism 3. The installation and fixing mechanism 3 includes an installation plate 301. The installation plate 301 is fixedly connected to the outer wall of the double-layer inflatable tube body 7. The inside of the installation plate 301 and the top of the coating machine body 1 are both provided with threaded holes 302. The inner wall of the threaded hole 302 is threaded with bolts 303.

[0028] Specifically: When the device is needed for inflation, the double-layer inflation tube body 7 must first be installed into the coating machine body 1. At this time, the double-layer inflation tube body 7 is inserted into the through hole at the top of the coating machine body 1, and the double-layer inflation tube body 7 passes through the scraper ring 209, so that the bottom of the mounting plate 301 on the outer wall of the double-layer inflation tube body 7 is in close contact with the top of the coating machine body 1. Then, the threaded hole 302 on the mounting plate 301 is aligned with the threaded hole 302 on the coating machine body 1, and then the bolt 303 is rotated and inserted into the threaded hole 302, thereby fixing the mounting plate 301 to the coating machine body 1, thus completing the installation and fixing work.

[0029] The working principle of this utility model is as follows: When the device is needed for inflation, the double-layer inflation tube body 7 is first installed into the coating machine body 1. The double-layer inflation tube body 7 is then inserted into the through hole at the top of the coating machine body 1, and passes through the scraper ring 209, so that the bottom of the mounting plate 301 on the outer wall of the double-layer inflation tube body 7 is tightly attached to the top of the coating machine body 1. Then, the threaded hole 302 on the mounting plate 301 is aligned with the threaded hole 302 on the coating machine body 1. Align the mounting plate 301 with the coating machine body 1 by rotating bolt 303 and inserting it into threaded hole 302. Then, open door panel 4 using handle 5. Sealing ring 6 ensures no air leakage inside coating machine body 1. Place the substrate to be coated into coating machine body 1. Connect the top of double-layer inflation tube body 7 to a pipe, and evenly release gas into coating machine body 1 through double-layer inflation tube body 7, thus ensuring the gas is evenly distributed inside the coating machine body 1. Evaporation materials are mixed to generate a specific compound film. During film formation, a certain film may form on the outer wall of the double-layer inflation tube body 7, which may block the inflation holes on the double-layer inflation tube body 7. At this time, it is necessary to scrape and clean the film on the double-layer inflation tube body 7. Then, the motor 205 is started, which drives the motor shaft 206 to rotate. The motor shaft 206 drives the gear 207 to rotate. The gear 207 drives the motor shaft 206 to move through the rack 202 on the fixed block 201. The motor shaft 206 drives the motor bracket 204 to move through the motor 205. The motor bracket 204 drives the connecting rod 208 to move. During the movement of the connecting rod 208, the sliding of the motor bracket 204 in the slide rail 203 makes the movement of the connecting rod 208 more stable and smooth. The connecting rod 208 drives the scraper ring 209 to move, so that the scraper ring 209 scrapes and cleans the film formed on the outer wall of the double-layer inflation tube body 7, thereby completing the scraping and cleaning work.
