Description

Technical Field

[0001] The present invention relates to the technical field of plate processing, and more specifically, to a coating device for producing rock wool boards. Background Art

[0002] Rock wool board, also known as rock wool insulation decorative board, is made of basalt as the main raw material and is processed by high-temperature melting. As an important building material, rock wool board often needs to be coated during the production process to enhance its performance and appearance. This process requires a coating device.

[0003] Existing coating devices are mostly composed of multiple groups of conveying rollers, glue coating rollers and conveyor belts, and their working principles are as follows: first, the rock wool board to be coated is placed on the surface of the conveyor belt and transported by the conveyor belt, and then the conveyor roller transports the film toward the rock wool board. During the conveying process, the conveyor roller first heats the film to improve the bonding effect. Then, when the film passes through the glue coating roller, the glue coating roller applies glue to its sticky surface. Finally, the conveyor roller presses the heated and glued film together with the rock wool board, thereby completing the coating process.

[0004] However, when the existing glue coating roller is coating the rock wool board with glue, due to the different sizes of the film and the glue coating roller, when the size of the film is smaller than the size of the glue coating roller, the glue overflowing from both ends of the glue coating roller cannot adhere to the film and be effectively utilized, which causes the glue to accumulate and possibly solidify, and eventually blocks the glue outlet of the glue coating roller, which not only affects the continuity of the glue coating operation, but also may damage the glue coating roller and shorten its service life. The accumulated glue cannot perform normal adhesion operations, thus causing unnecessary waste of glue, which not only increases the use cost of the device, but also may cause a certain burden on the environment.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 6 As shown, a film coating device for producing rock wool board comprises a pair of conveyor belts 2 mounted on the inner wall of a conveyor frame 1, and the top of the conveyor belt 2 is respectively provided with a glue coating roller 3 and a plurality of groups of conveying rollers, and the conveying rollers are used for conveying, heating and film pressing, and both ends of the glue coating roller 3 are rotated with a first connecting frame 4, and a pair of the first connecting frames 4 are fixedly connected to the top of the conveyor frame 1, and the film coating device also comprises:

[0031] A scraper 5 is arranged on the outside of the glue coating roller 3, and a glue collecting box 6 is fixedly connected to both ends of the scraper 5. A first sprocket 7 is fixedly connected to the outside of one end of the glue coating roller 3, and a second sprocket 8 is arranged on the periphery of the first sprocket 7. A chain 9 is meshed on the outside of the first sprocket 7 and the second sprocket 8, and a reciprocating mechanism for reciprocating the glue collecting box 6 is arranged inside the second sprocket 8;

[0032] A baffle 10, a pair of baffles 10 are provided, and the pair of baffles 10 are symmetrically arranged at the inner bottom end of the glue collecting box 6, and the inside of the pair of baffles 10 is fixedly connected with a side rod 11, and the side rod 11 is rotatably connected to the inner wall of the glue collecting box 6, and the end of the side rod 11 away from the glue collecting box 6 penetrates the glue collecting box 6 and extends to the outside of the glue collecting box 6, and the top of the pair of side rods 11 is provided with a rack 12, and the bottom end of the pair of racks 12 is fixedly connected with a first fixed rod 13, and the first fixed rod 13 is fixedly connected to the top of the conveying frame 1, and the outer side of the side rod 11 is fixedly connected with a coil spring 60, and the end of the coil spring 60 away from the side rod 11 is fixedly connected to the outer side of the glue collecting box 6, and the periphery of the side rod 11 is provided with a rotating mechanism for rotating the baffle 10.

[0033] First, the rock wool board to be coated is placed on the surface of the conveyor belt 2 and conveyed by the conveyor belt 2, and then the conveyor roller conveys the film toward the rock wool board. During the conveying process, the conveyor roller first heats the film to improve the bonding effect. Subsequently, when the film passes through the glue coating roller 3, the glue coating roller 3 applies glue to its sticky surface. It should be noted that the conveyor roller and the glue coating roller 3 are both conventional technologies of the existing laminating machine and are not elaborated in detail in the present invention. Finally, the conveyor roller adheres the heated and glued film to the rock wool board in a pressing manner, thereby completing the coating process. However, when the existing glue coating roller 3 is used to coat the rock wool board with glue, due to the different sizes of the film and the glue coating roller 3, when the size of the film is smaller than the size of the glue coating roller 3, the glue overflowing from both ends of the glue coating roller 3 cannot adhere. The glue coating roller 3 is not effectively utilized on the film, which causes the glue to accumulate and possibly solidify, and finally blocks the glue outlet of the glue coating roller 3, which not only affects the continuity of the glue coating operation, but also may damage the glue coating roller 3 and shorten its service life. The accumulated glue cannot perform normal adhesion operations, thus causing unnecessary glue waste. This waste not only increases the use cost of the device, but also may cause a certain burden on the environment. When the embodiment of the present invention is in use, when the glue coating roller 3 rotates, it will drive the first sprocket 7 to rotate, and the rotation of the first sprocket 7 will drive the second sprocket 8 to rotate through the chain 9, and the rotation of the second sprocket 8 will drive the reciprocating mechanism to operate. The reciprocating mechanism then drives the glue collecting box 6 to reciprocate along the outer side of the glue coating roller 3, and the movement of the glue collecting box 6 will The scraper 5 is driven to move, and there is a certain gap between the scraper 5 and the glue coating roller 3. When the scraper 5 moves back and forth, the glue accumulated on the edge will be scraped off, preventing the glue from falling directly on the surface of the conveyor belt 2, and the scraped glue will fall directly into the glue collecting box 6 under the action of gravity for unified collection, and the reciprocating glue scraping action of the scraper 5 also realizes the operation of scraping the glue evenly, so that the glue is evenly attached to the outside of the glue coating roller 3. When the glue collecting box 6 moves horizontally to the specified position under the action of the reciprocating mechanism, the rotating mechanism on the periphery of the side rod 11 contacts the rack 12, and the rotating mechanism operates, and the operation of the rotating mechanism drives the side rod 11 to rotate, and the rotation of the side rod 11 drives the baffle 10 to open, and the rotation of the side rod 11 also drives the coil spring 60 Deformation generates elastic potential energy. In the initial state, a pair of baffles 10 are in a state of sealing the bottom end of the glue collecting box 6. When the baffles 10 are opened, the glue falling into the glue collecting box 6 will fall again under the action of gravity, thereby escaping from the inside of the glue collecting box 6. The position where the baffles 10 are opened is not at the top of the conveyor belt 2. At this time, the internal glue of the glue collecting box 6 will not accumulate on the top of the conveyor belt 2 when it falls, thereby avoiding contamination of the conveyor belt 2 and reducing the service life of the conveyor belt 2. When the glue collecting box 6 drives the rotating mechanism through the side rod 11 and detaches from the top of the rack 12, the rotating force of the rotating mechanism on the side rod 11 ends, and the coil spring 60 releases the elastic potential energy, drives the baffle 10 to reset through the side rod 11, and seals the bottom end of the glue collecting box 6 again.

[0034] like Figure 2 and Figure 3 As shown, the reciprocating mechanism includes a positive and negative threaded rod 14, a pair of second connecting frames 15, a threaded plate 16, a slider and a limit rod 17. The pair of second connecting frames 15 are respectively fixed to the top ends of a pair of conveying frames 1, and the two ends of the positive and negative threaded rod 14 are respectively rotatably connected to the pair of second connecting frames 15. The threaded plate 16 is fixed to the outer side of the glue collection box 6, and the slider is fixed to the inside of the threaded plate 16. The slider is threadedly connected to the outer side of the positive and negative threaded rod 14, and the two ends of the limit rod 17 are respectively fixed to the pair of second connecting frames 15, and the limit rod 17 passes through the threaded plate 16.

[0035] When the positive and negative threaded rods 14 rotate, they will drive the slider inside the threaded plate 16 to move back and forth, and when the slider moves, it will drive the threaded plate 16 to move. The reciprocating movement of the threaded plate 16 will pass through the glue collecting box 6, driving the scraper 5 to reciprocate and scrape off and evenly distribute the glue accumulated on the outside of the glue coating roller 3. The setting of the limit rod 17 can limit the threaded plate 16, ensuring that the threaded plate 16 is always on the outside of the limit rod 17 when moving, avoiding shaking of the threaded plate 16 when moving.

[0036] like Figure 4 , Figure 5 and Figure 6 As shown, the rotating mechanism includes a first spur gear 18, a second spur gear 19 and a transmission rod 20, the first spur gear 18 is fixedly connected to the outer side of the side rod 11, the second spur gear 19 is meshed with the side rod 11, the transmission rod 20 is rotatably connected to the inside of the second spur gear 19, and the end of the transmission rod 20 away from the second spur gear 19 is fixedly connected to the outer side of the glue collection box 6.

[0037] When the glue collecting box 6 moves, it will drive the side rod 11 and the transmission rod 20 to move. The movement of the transmission rod 20 will drive the second spur gear 19 to move, and the movement of the side rod 11 will drive the first spur gear 18 to move. When the second spur gear 19 moves horizontally for a distance, the second spur gear 19 will contact the rack 12. Since the position of the rack 12 is fixed, when the second spur gear 19 continues to move, the second spur gear 19 will rotate under the action of the rack 12, and the rotation of the second spur gear 19 will drive the first spur gear 18 to rotate. The rotation of the first spur gear 18 will drive the baffle 10 to flip through the side rod 11, thereby opening the seal of the glue collecting box 6. When the second spur gear 19 passes over the rack 12, the coil spring 60 will drive the baffle 10 to reset through the side rod 11.

[0038] like Figure 6As shown, a pair of concave plates 21 are disposed inside the adhesive collecting box 6 , and a pulling mechanism matched with the concave plates 21 is disposed on the periphery of the baffle 10 , and the pulling mechanism is used to lift the concave plates 21 .

[0039] When the glue falls into the glue collection box 6, part of the glue may adhere to the inner wall of the glue collection box 6. In practical use, when the baffle 10 is flipped, the baffle 10 will drive the pulling mechanism to operate, and the pulling mechanism will drive the concave plate 21 to move downward. The concave plate 21 moves downward and always fits the inner wall of the glue collection box 6, thereby scraping off the glue adhered to the inner wall of the glue collection box 6. When the baffle 10 is reset, the pulling mechanism is reset synchronously, driving the concave plate 21 to move up and return to the initial position.

[0040] like Figure 6 As shown, the pulling mechanism includes a pair of guide rods 22, a square plate 23 and a connecting rod 24. The pair of guide rods 22 both penetrate the concave plate 21. The square plates 23 are respectively fixed to the top ends of the pair of guide rods 22. The square plates 23 are fixed to the top ends of the glue collecting box 6. The two ends of the connecting rod 24 are respectively hinged to the concave plate 21 and the baffle 10.

[0041] When the baffle 10 flips over, the concave plate 21 will be pulled through one end of the connecting rod 24, and the concave plate 21 will move downward along the guide rod 22 under the limit of the guide rod 22, and the glue attached to the inner wall of the glue collection box 6 will be scraped off. When the baffle 10 is reset, the baffle 10 will squeeze one end of the connecting rod 24, and the connecting rod 24 will be pushed by the force to move the concave plate 21 upward and reset.

[0042] like Figure 7 As shown, a pair of the conveying racks 1 are fixedly connected to the top ends with a storage box 25, an electromagnetic valve 26 is installed on the outside of the storage box 25, and an inclined block 27 is fixedly connected to the inner wall of the storage box 25, and the inclined block 27 is designed as a "right triangle".

[0043] When the baffle 10 is flipped open, the glue collecting box 6 just moves to the top of the storage box 25. At this time, the internal glue of the glue collecting box 6 will fall into the interior of the storage box 25 under the action of gravity, which is convenient for subsequent collection. When the internal glue of the storage box 25 is collected to a certain extent, the solenoid valve 26 can be controlled to open, and the internal glue of the storage box 25 will flow into the designated position through the solenoid valve 26. The inclined block 27 is designed in a "right triangle" to ensure that the internal glue of the storage box 25 flows in the direction of the solenoid valve 26.

[0044] like Figure 5 , Figure 6 and Figure 7As shown, the top ends of a pair of the conveying racks 1 are fixedly connected with a second fixing rod 28, the end of the second fixing rod 28 away from the conveying rack 1 is fixedly connected with a first magnetic block 29, and the bottom ends of a pair of the baffles 10 are fixedly connected with a second magnetic block 30, and the first magnetic block 29 and the second magnetic block 30 are attracted to each other in opposite polarities.

[0045] When the baffle 10 is flipped open, the second spur gear 19 needs to be in meshing state with the rack 12, and this process time is short, and the glue inside the glue collection box 6 may not drip completely, thereby causing the glue inside the glue collection box 6 to continue to accumulate. When the embodiment of the present invention is used, when the baffle 10 is flipped open, the second magnetic block 30 at the bottom of the baffle 10 is as shown in FIG. Figure 7 As shown, it is just within the magnetic attraction range of the first magnetic block 29. Even when the second spur gear 19 is disengaged from the rack 12, the attraction between the first magnetic block 29 and the second magnetic block 30 can overcome the elastic potential energy released by the coil spring 60, ensuring that the baffle 10 remains in a flipped state, which can increase the opening time of the baffle 10 and provide sufficient time for the glue inside the glue collection box 6 to drip.

[0046] like Figure 6 As shown, the top ends of the pair of concave plates 21 are of “chamfered” design.

[0047] The “chamfered” design of the concave plate 21 can ensure that the glue will not accumulate on the top of the concave plate 21 when it falls into the glue collecting box 6. When the glue is at the top of the concave plate 21, the glue will flow down along the inclined surface of the concave plate 21.

[0048] Working principle: First, the rock wool board to be coated is placed on the surface of the conveyor belt 2 and conveyed by the conveyor belt 2, and then the conveyor roller conveys the film toward the direction of the rock wool board. During the conveying process, the conveyor roller first heats the film to improve the bonding effect. Then, when the film passes through the glue coating roller 3, the glue coating roller 3 applies glue to its sticky surface. When the glue coating roller 3 rotates, it also drives the first sprocket 7 to rotate. The rotation of the first sprocket 7 drives the second sprocket 8 to rotate through the chain 9. The rotation of the second sprocket 8 drives the positive and negative threaded rods 14 to rotate, and the positive and negative threaded rods 14 drive the threaded plate 16 The internal slider moves back and forth, and the slider will drive the threaded plate 16 to move when moving. The reciprocating movement of the threaded plate 16 will pass through the glue collecting box 6, driving the scraper 5 to move back and forth. There is a certain gap between the scraper 5 and the glue coating roller 3. When the scraper 5 moves back and forth, the glue accumulated on the edge will be scraped off, avoiding the glue from falling directly on the surface of the conveyor belt 2. The scraped glue will fall directly into the glue collecting box 6 under the action of gravity for unified collection. The reciprocating scraping action of the scraper 5 also realizes the operation of scraping the glue evenly, so that the glue is evenly attached to the outer side of the glue coating roller 3.

[0049] When the glue collecting box 6 moves back and forth laterally, it will drive the side rod 11 and the transmission rod 20 to move. The movement of the transmission rod 20 will drive the second spur gear 19 to move, and the movement of the side rod 11 will drive the first spur gear 18 to move. After the second spur gear 19 moves laterally for a distance, the second spur gear 19 will contact the rack 12. Since the position of the rack 12 is fixed, when the second spur gear 19 continues to move, the second spur gear 19 will rotate under the action of the rack 12, and the rotation of the second spur gear 19 will drive the first spur gear 18 to rotate. The rotation of the first spur gear 18 will drive the baffle 10 to flip through the side rod 11, thereby opening the seal of the glue collecting box 6. When the second spur gear 19 passes over the rack 12, the coil spring 60 will drive the baffle 10 to reset through the side rod 11, and the bottom end of the glue collecting box 6 will be sealed again.

[0050] When the baffle 10 is turned over, the baffle 10 will pull the concave plate 21 through one end of the connecting rod 24, and the concave plate 21 will move down along the guide rod 22 under the limit of the guide rod 22, so as to scrape off the glue attached to the inner wall of the glue collecting box 6, and when the baffle 10 is reset, the baffle 10 will squeeze one end of the connecting rod 24, and the connecting rod 24 will push the concave plate 21 to move up and reset, so as to drive the concave plate 21 back to the initial position;

[0051] When the baffle 10 is flipped open, the glue collecting box 6 above the baffle 10 just moves to the top of the storage box 25. At this time, the glue inside the glue collecting box 6 will fall into the storage box 25 under the action of gravity, which is convenient for subsequent collection. When the glue inside the storage box 25 is collected to a certain extent, the solenoid valve 26 can be controlled to open, and the glue inside the storage box 25 will flow into the designated position through the solenoid valve 26. The design of the inclined block 27 in a "right triangle" can ensure that the glue inside the storage box 25 flows in the direction of the solenoid valve 26.

[0052] When the baffle 10 is flipped open, the second magnetic block 30 at the bottom of the baffle 10 Figure 7 As shown, it is just within the magnetic attraction range of the first magnetic block 29. Even when the second spur gear 19 is disengaged from the rack 12, the attraction between the first magnetic block 29 and the second magnetic block 30 can overcome the elastic potential energy released by the coil spring 60, ensuring that the baffle 10 remains in a flipped state, which can increase the opening time of the baffle 10 and provide sufficient time for the glue inside the glue collection box 6 to drip.

[0053] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
