Description

Technical Field

[0001] This invention belongs to the field of glass coating technology, specifically a coating device for the surface of insulating glass ceramics. Background Technology

[0002] Insulating glass is a new type of building material that offers excellent heat and sound insulation, aesthetic appeal, and reduced building weight. It consists of two or three panes of glass bonded to an aluminum alloy frame containing a desiccant using a high-strength, airtight composite adhesive, resulting in high-performance sound and heat insulation. Glass coating machines, as an important piece of equipment in the glass production process, provide advantages such as increased glass strength and reduced scratches after coating.

[0003] For example, CN113977924A discloses a type of coated glass for producing heat-insulating coated glass, including a frame with several conveyor rollers for horizontally conveying glass. A film material roller is rotatably connected to the frame, with film material wound on it for unwinding. A coating roller is rotatably connected to the frame, with one end of the unwound film material leading to the coating roller for attaching the coating to the glass. A roller assembly is rotatably connected to both sides of the frame, comprising several rollers that are sequentially meshed. An elastic rope is connected between the front and rear rollers, and the elastic rope is connected to an eccentric position on the roller. When the glass reaches the front end of the roller assembly, it first pushes the elastic rope at the front end to scrape the top of the glass. Simultaneously, through the transmission of the roller assembly, it drives the elastic rope at the rear end to scrape the top of the coated glass, further pressing, leveling, and effectively removing defects such as air bubbles.

[0004] Although the above-mentioned device can remove air bubbles from the coated glass, in practice, it is still necessary to manually cut the film on the glass after coating to ensure that the protective film is completely adhered to the insulating glass. However, the manual cutting of the film often reduces the cutting efficiency due to the increase in working hours, thereby reducing the coating efficiency. At the same time, the above-mentioned device also occupies a lot of space, further reducing the coating efficiency of the device. Therefore, an insulating glass ceramic surface coating device is proposed to solve the problems mentioned in the background art. Summary of the Invention

[0005] To address the problems mentioned in the background art, the present invention provides a coating device for the surface of hollow glass ceramics, which solves the problems of existing coating devices having a large footprint and the reduction in coating efficiency due to the addition of manpower.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for coating the surface of hollow glass ceramics, comprising a support frame, a roller, an electro-hydraulic rod, a protective film, and a glass ceramic body. A first limiting rod is fixedly connected to the top perimeter of the support frame. A second limiting rod is sleeved on the outer surface of the first limiting rod. A first spring is sleeved on the outer surface of the second limiting rod. One end of the electro-hydraulic rod penetrates the top of the support frame and is fixedly connected to a top cover.

Limiting crossbars are movably connected to the front and rear ends of the inner cavity of the lower cylinder. The inner cavities at both ends of the rod are movably connected to a third limiting rod. A second spring is sleeved on the outer surface of the third limiting rod. A limiting block is sleeved on the outer surface of one side of the limiting crossbar. Rollers are movably engaged at the front and rear ends of the inner cavity of the top of the limiting block. A fourth limiting rod and a third spring are fixedly connected to the front and rear ends of the top of the inner cavity of the limiting block. A scraper is movably connected to the inner cavity of the limiting block. A first tension spring is fixedly connected at equal intervals to the inner cavities of the front and rear ends of the top of the cutting block. Inclined grooves are opened at the front and rear ends of the lower cylinder. Fixing mechanisms are movably engaged at the four corners of the inner cavity of the support frame. A positioning mechanism is movably engaged at the front and rear ends of the inner cavity on one side of the support frame.

[0007] Preferably, the fixing mechanism includes a clamping block, which is movably engaged around the inner cavity of the support frame. A first inclined block located directly above the clamping block is fixedly connected around the bottom of the lower cylinder, and a second tension spring is fixedly connected to the inner cavity of the clamping block.

[0008] Preferably, the positioning mechanism includes a second inclined block, which is movably engaged with the front and rear ends of one side of the inner cavity of the support frame. Spring plates are fixedly connected at equal intervals to the bottom of the second inclined block. A top plate is movably engaged with the inner cavity of the second inclined block on the side away from the clamping block. A third tension spring is fixedly connected to the inner cavity of the top plate in the middle of the side near the clamping block.

[0009] Preferably, the outer surface of the first limiting rod is also movably connected to the inner cavity of the lower cylinder, the outer surface of the second limiting rod is movably connected to the inner cavity of the upper cover, the bottom of the second limiting rod is fixedly connected to the lower cylinder, and the top and bottom of the first spring are fixedly connected to the upper cover and the lower cylinder, respectively.

[0010] Preferably, the cutting block is positioned directly above the glass ceramic body, and the inner wall of the cutting block mates with the side wall of the glass ceramic body. Both ends of the third limiting rod are fixedly connected to the lower cylinder. The top and bottom of the second spring are fixedly connected to the limiting crossbar and the lower cylinder, respectively. The front and rear ends of both sides of the top of the cutting block are provided with protruding columns, and the top of the protruding columns mates with the lower surface of the limiting crossbar for compression.

[0011] Preferably, both ends of the limiting block are also movably connected to the inner cavity of the inclined groove, the outer surface of the roller contacts the top of the inner cavity of the upper cover, the third spring is sleeved on the outer surface of the fourth limiting rod, and one end of the bottom of the fourth limiting rod is fixedly connected to the scraper block.

[0012] Preferably, one end of the bottom of the scraper is made of rubber material and the two sides of the bottom of the scraper are beveled. The inner cavity of the top of the scraper is movably connected to the outer surface of the fourth limiting rod. The scraper is located on one side above the glass ceramic body.

[0013] Preferably, the rollers are movably connected to the inner cavities at both ends of the support frame, and the rollers at both ends are conveying rollers and winding rollers, respectively. The two ends of the protective film are wound around the rollers on both sides, and the middle part of the protective film is located between the top of the glass ceramic body and the bottom of the lower cylinder. Guide rollers are evenly arranged in the inner cavity at the top of the support frame, and the glass ceramic body is placed above the guide rollers.

[0014] Preferably, one end of the top of the clamping block penetrates the side wall of the support frame, and both the top and bottom ends of the clamping block are inclined. The bottom end of the first inclined block is engaged with the top of the clamping block for compression, and the outer end of the second tension spring is fixedly connected to the support frame.

[0015] Preferably, the end of the second inclined block near the clamping block is inclined and matches the inclined surface at the bottom of the clamping block. The end of the second inclined block away from the clamping block passes through the support frame and extends to the top of the support frame to contact the glass ceramic body. The end of the top plate near the clamping block is located at the middle of the height of the side wall of the glass ceramic body and contacts the roller. The end of the third tension spring near the clamping block is fixedly connected to the second inclined block, and the bottom end of the third tension spring is fixedly connected to the support frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention improves the efficiency of coating glass and ceramic bodies by coordinating structures such as limiting crossbars, rollers, lower cylinders, and limiting blocks. When the lower surface of one end of the first inclined block contacts the top of the support frame, one end of the scraper will contact the upper surface of the protective film. At this time, the continued operation of the electric hydraulic rod will cause the upper cover to continue to move downward under the limiting action of the first limiting rod, thereby squeezing the roller and causing the limiting block to move along the fixing mechanism under the limiting action of the limiting crossbar. This allows one end of the scraper to scrape and remove air bubbles from the upper surface of the protective film. When the limiting block moves completely to the bottom of the inclined groove, it will also drive the limiting crossbar to move downward and squeeze the protrusion on the top of the cutting block, thereby squeezing the cutting block to move downward to cut the protective film.

[0018] The present invention utilizes the cooperation between the clamping block, the first inclined block, the second tension spring, and the upper cover to enable the device to effectively fix the glass ceramic body. By operating the electric hydraulic rod, the upper cover, through the cooperation between the second limiting rod and the first spring, causes the lower cylinder to move downward. When the lower cylinder moves downward, the first inclined block at the bottom of the lower cylinder will first contact the clamping block and squeeze the clamping block to move towards the side closer to the glass ceramic body, thereby fixing the clamping block.

[0019] This invention utilizes the cooperation between the second inclined block, spring plate, top plate, and third tension spring to enable the device to quickly position the glass ceramic body. The guide roller above the support frame drives the glass ceramic body to move closer to the second inclined block. When the end of the glass ceramic body close to the second inclined block contacts the top plate and compresses the top plate to move completely into the interior of the second inclined block, the glass ceramic body is directly below the lower cylinder, thus completing the positioning of the glass ceramic body and facilitating the subsequent coating operation of the glass ceramic body.

[0030] The technical solutions of the embodiments of the present invention 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.

[0031] like Figures 1 to 9As shown, this invention provides a device for coating the surface of hollow glass ceramics, including a support frame 1, a roller 17, an electro-hydraulic rod 16, a protective film 18, and a glass ceramic body 19. A first limiting rod 2 is fixedly connected to the top perimeter of the support frame 1. A second limiting rod 3 is sleeved on the outer surface of the first limiting rod 2. A first spring 4 is sleeved on the outer surface of the second limiting rod 3. One end of the bottom of the electro-hydraulic rod 16 penetrates the top of the support frame 1 and is fixedly connected to an upper cover 5. A lower cylinder 6 is movably connected to the inner cavity of the upper cover 5. The inner cavity of the lower cylinder 6... A cutting block 7 is movably engaged at the bottom. A limiting crossbar 10 is movably connected to the front and rear ends of the inner cavity of the lower cylinder 6. A third limiting rod 8 is movably connected to the inner cavities at both ends of the limiting crossbar 10. A second spring 9 is sleeved on the outer surface of the third limiting rod 8. A limiting block 11 is sleeved on the outer surface of one side of the limiting crossbar 10. Rollers 12 are movably engaged at the front and rear ends of the inner cavity of the top of the limiting block 11. A fourth limiting rod 13 and a third spring 14 are fixedly connected to the front and rear ends of the top of the inner cavity of the limiting block 11. A scraper 15 is movably connected to the inner cavity of the limiting block 11. The inner cavities at the front and rear ends of the top of the cutting block 7 are fixedly connected with first tension springs 20 at equal intervals. The front and rear ends of the lower cylinder 6 are provided with inclined grooves 21. The four corners of the inner cavity of the support frame 1 are movably engaged with fixing mechanisms 22, and the front and rear ends of one side of the inner cavity of the support frame 1 are movably engaged with positioning mechanisms 23. When the lower surface of one end of the first inclined block 222 contacts the top of the support frame 1, one end of the bottom of the scraper block 15 will contact the upper surface of the protective film 18. At this time, the continued operation of the electric hydraulic rod 16 will be limited by the first limit rod 2. Under the action of the position, the upper cover 5 continues to move downward, thereby squeezing the roller 12 and under the limiting action of the limiting crossbar 10, the limiting block 11 moves along the fixing mechanism 22, thereby causing one end of the bottom of the scraper block 15 to scrape and remove air bubbles from the upper surface of the protective film 18. When the limiting block 11 moves completely to one end of the bottom of the inclined groove 21, it will also drive the limiting crossbar 10 to move downward and squeeze the protrusion on the top of the cutting block 7, thereby squeezing the cutting block 7 to move downward to cut the protective film 18.

[0032] like Figure 5 , Figure 6 and Figure 9As shown, the fixing mechanism 22 includes a clamping block 221, which is movably engaged around the inner cavity of the support frame 1. A first inclined block 222 located directly above the clamping block 221 is fixedly connected around the bottom of the lower cylinder 6. A second tension spring 223 is fixedly connected to the inner cavity of the clamping block 221. One end of the top of the clamping block 221 penetrates the side wall of the support frame 1. Both the top and bottom ends of the clamping block 221 are inclined. The bottom end of the first inclined block 222 engages with the top of the clamping block 221 to press against it. The outer end of the second tension spring 223 is fixedly connected to the support frame 1. By operating the electric hydraulic rod 16, the upper cover 5 moves the lower cylinder 6 downward through the engagement between the second limiting rod 3 and the first spring 4. When the lower cylinder 6 moves downward, the first inclined block 222 at the bottom of the lower cylinder 6 will first contact the clamping block 221 and press the clamping block 221 to move towards the side closer to the glass ceramic body 19, thereby fixing the clamping block 221.

[0033] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 9 As shown, the positioning mechanism 23 includes a second inclined block 231, which is movably engaged with the front and rear ends of one side of the inner cavity of the support frame 1. Spring plates 232 are fixedly connected at equal intervals to the bottom of the second inclined block 231. A top plate 233 is movably engaged with the inner cavity of the top of the second inclined block 231 on the side away from the clamping block 221. A third tension spring 234 is fixedly connected to the inner cavity of the top plate 233 near the middle of the side of the clamping block 221. The end of the second inclined block 231 near the clamping block 221 is inclined and cooperates with the inclined surface at the bottom of the clamping block 221. The end of the second inclined block 231 away from the clamping block 221 penetrates the support frame 1 and extends to the top of the support frame 1, contacting the glass ceramic body 19. The end of the top plate 233 near the clamping block 221... The glass ceramic body 19 is located at the middle of its side wall height and in contact with the roller 17. The end of the third tension spring 234 near the clamping block 221 is fixedly connected to the second inclined block 231, and the bottom end of the third tension spring 234 is fixedly connected to the support frame 1. The guide roller above the support frame 1 drives the glass ceramic body 19 to move towards the side closer to the second inclined block 231. Thus, when the end of the glass ceramic body 19 near the second inclined block 231 contacts the top plate 233 and squeezes the top plate 233 to move completely into the interior of the second inclined block 231, the glass ceramic body 19 is directly below the lower cylinder 6, thereby completing the positioning of the glass ceramic body 19 to facilitate the subsequent coating operation of the glass ceramic body 19.

[0034] It is worth noting that when the clamping block 221 moves towards the side closer to the glass ceramic body 19 and fixes the glass ceramic body 19, the clamping block 221 will also compress the second tension spring 223, causing the second tension spring 223 to move downward and move to the area between the bottom of the glass ceramic body 19 and the top of the support frame 1. At this time, due to the pulling force of the third tension spring 234, the second tension spring 223 will move towards the side closer to the glass ceramic body 19, thereby preventing the clamping block 221 from moving upward, thus facilitating the subsequent cutting and use of the glass ceramic body 19.

[0035] It is worth noting that after the glass ceramic body 19 is finished being cut, the second inclined block 231 is reset under the action of the spring plate 232, which makes it easier for the device to position the next glass ceramic body 19.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the outer surface of the first limiting rod 2 is movably connected to the inner cavity of the lower cylinder 6, the outer surface of the second limiting rod 3 is movably connected to the inner cavity of the upper cover 5, the bottom of the second limiting rod 3 is fixedly connected to the lower cylinder 6, the top and bottom of the first spring 4 are fixedly connected to the upper cover 5 and the lower cylinder 6 respectively, the cutting block 7 is located directly above the glass ceramic body 19, and the inner wall of the cutting block 7 matches the side wall of the glass ceramic body 19, both ends of the third limiting rod 8 are fixedly connected to the lower cylinder 6, the top and bottom of the second spring 9 are fixedly connected to the limiting crossbar 10 and the lower cylinder 6 respectively, and the top two sides of the cutting block 7 are fixedly connected to the lower cylinder 6. Both the front and rear ends are equipped with protruding pillars, the top of which engages with and presses against the lower surface of the limiting crossbar 10. The design of the first limiting rod 2 limits the downward movement of the second limiting rod 3, the upper cover 5, and the lower cylinder 6. At the same time, the design of the first spring 4 resets the upper cover 5 and the lower cylinder 6. The engagement between the protruding pillars on the cutting block 7 and the limiting crossbar 10 facilitates the cutting of the glass ceramic body 19 by the subsequent scraper block 15, saving manpower, conserving space, and thus improving the coating efficiency of the device.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, both ends of the limiting block 11 are also movably connected to the inner cavity of the inclined groove 21. The outer surface of the roller 12 contacts the top of the inner cavity of the upper cover 5. The third spring 14 is sleeved on the outer surface of the fourth limiting rod 13. One end of the bottom of the fourth limiting rod 13 is fixedly connected to the scraper 15. One end of the bottom of the scraper 15 is made of rubber material, and the two sides of the bottom of the scraper 15 are inclined. The inner cavity at the top of the scraper 15 is movably connected to the outer surface of the fourth limiting rod 13. The scraper 15 is located on one side above the glass ceramic body 19. One end of the bottom of the scraper 15 is made of rubber material and The bottom sides of the scraper 15 are inclined, and the inner cavity at the top of the scraper 15 is movably connected to the outer surface of the fourth limiting rod 13. The scraper 15 is located on one side above the glass ceramic body 19. Through the cooperation between the limiting block 11 and the inclined groove 21, when the upper cover 5 moves downward to squeeze the roller 12, the two ends of the limiting block 11 will move under the limiting effect of the inclined groove 21, which facilitates the subsequent device to coat the glass ceramic body 19 and remove air bubbles. The design of the fourth limiting rod 13 plays a limiting role in the movement of the scraper 15.

[0038] Working principle and usage process of this invention:

[0039] First, the guide roller above the support frame 1 drives the glass ceramic body 19 to move towards the side closer to the second inclined block 231. Thus, when the end of the glass ceramic body 19 close to the second inclined block 231 contacts the top plate 233 and squeezes the top plate 233 to move completely into the interior of the second inclined block 231, the glass ceramic body 19 is directly below the lower cylinder 6, thereby completing the positioning of the glass ceramic body 19, so as to facilitate the subsequent coating operation of the glass ceramic body 19.

[0040] The operation of the electric hydraulic rod 16 causes the upper cover 5 to move the lower cylinder 6 downward through the cooperation between the second limit rod 3 and the first spring 4. When the lower cylinder 6 moves downward, the first inclined block 222 at the bottom of the lower cylinder 6 will first contact the clamping block 221 and squeeze the clamping block 221 to move towards the side closer to the glass ceramic body 19, thereby fixing the clamping block 221 and completing the operation.

[0041] When the lower surface of one end of the first inclined block 222 contacts the top of the support frame 1, one end of the bottom of the scraper block 15 will contact the upper surface of the protective film 18. At this time, the continued operation of the electric hydraulic rod 16 will cause the upper cover 5 to continue to move downward under the limiting action of the first limiting rod 2, thereby squeezing the roller 12 and causing the limiting block 11 to move along the inclined groove 21 under the limiting action of the limiting crossbar 10. This allows one end of the bottom of the scraper block 15 to scrape and remove air bubbles from the upper surface of the protective film 18. When the limiting block 11 moves completely to one end of the bottom of the inclined groove 21, it will also drive the limiting crossbar 10 to move downward and squeeze the protrusion on the top of the cutting block 7, thereby squeezing the cutting block 7 to move downward to cut the protective film 18 and complete the operation.
