Description

Technical Field

[0001] This invention relates to the field of bubble removal in explosion-proof protective films, and particularly to a bubble removal device and process for explosion-proof protective films. Background Technology

[0002] An explosion-proof membrane is a thin metal film installed on the top of a pressure vessel to prevent it from exploding. It is a safety device, also known as an explosion-proof disc or rupture disc. When the pressure inside the vessel exceeds a certain limit, the membrane is ruptured first, thus reducing the pressure inside the vessel and preventing an explosion. It is widely used in pressure vessels. The term explosion-proof membrane sometimes specifically refers to the windshield membrane.

[0003] Chinese invention patent application number CN202221363050.2 discloses an online roller defoaming device for cover plate protective film, including a conveying base with a conveying device inside. Support frames are fixedly connected to both sides of the conveying base, and a lifting mechanism is provided on the support frame. Roller shafts are mounted on the lifting mechanism, and the same flexible roller for defoaming is rotatably connected to the side of the two roller shafts that are close to each other. Fixed frames are fixedly connected to both sides of the conveying base, with the fixed frames located in front of the support frames. A dust removal component is provided on the fixed frame, and a suction pipe for dust extraction is drivenly connected to the dust removal component. This device has low defoaming efficiency and lacks defoaming equipment for the bottom of the protective film. Furthermore, the lack of a limiting component for the protective film during defoaming affects the defoaming accuracy.

[0004] Therefore, it is necessary to propose an explosion-proof protective film defoaming device and its defoaming process to solve the above problems. Summary of the Invention

Electric sliders are symmetrically fixedly connected to the center of the opposite sides of the two reinforcing blocks.

[0007] Preferably, the limiting component is a cavity structure with its bottom communicating with the outside. A first hydraulic push rod is fixedly connected to the center of the front of the top of the pressure plate. The first hydraulic push rod is fixedly connected to the center of the top of the limiting component. First guide posts are symmetrically fixedly connected to the front and back of the top of the pressure plate. Two first guide posts are symmetrically movably connected to the front and back of the inner cavity of the top of the limiting component.

[0008] Preferably, the defoaming component is a cavity structure with its bottom communicating with the outside. The front and back of the inner cavity of the defoaming component are symmetrically provided with moving grooves. The moving block is movably connected in the inner cavity of the moving groove. A threaded rod is rotatably connected to the center of the inner cavity of the moving groove on the front side. The top of the threaded rod is fixedly connected to a second servo motor through a first rotating shaft. The second servo motor is fixedly connected to the front side of the inner cavity of the defoaming component. A second guide post is fixedly connected in the inner cavity of the moving groove on the back side. The moving block on the front side is threadedly connected to the outer wall of the moving block. The moving block on the back side is movably connected to the outer wall of the second guide post.

[0009] Preferably, the device body has symmetrical movable slots on the right side of the top front and back sides. A threaded column is rotatably connected in the inner cavity of the movable slot on the front side. A first servo motor is fixedly connected to the left side of the threaded column through a second rotating shaft. The first servo motor is fixedly connected to the top of the left front side of the device body.

[0010] Preferably, the bottom of the defoaming component has movable blocks symmetrically fixedly connected to the front and back sides, and the two movable blocks are symmetrically movably connected in the inner cavities of the two movable slots. The movable block on the front side is threadedly connected to the outer wall of the threaded column.

[0011] Preferably, hydraulic lifting rods are symmetrically fixedly connected to the left and right sides of the front and back of the device body, and the tops of the four hydraulic lifting rods are symmetrically fixedly connected to the left and right sides of the front and back of the pressure plate. The size of the pressure plate and the groove are matched, and an adaptation groove is opened on the right side of the bottom of the pressure plate.

[0012] Preferably, an adapter block is movably connected to the right side of the groove, and a second hydraulic push rod is fixedly connected to the bottom of the adapter block. The bottom of the second hydraulic push rod is fixedly connected to the bottom of the inner cavity of the equipment body.

[0013] Preferably, electric slide rails are symmetrically fixedly connected to the top of the front and back sides of the groove cavity, the electric slider is electrically connected to the electric slide rails, mounting blocks are symmetrically fixedly connected to the opposite right sides of the two reinforcing blocks, and bolts are symmetrically threaded to the top and bottom of the opposite right sides of the two mounting blocks, and the reinforcing blocks are threadedly connected to the plastic scraper by bolts.

[0014] A defoaming process for an explosion-proof protective film defoaming device includes the following steps: S1: Activate the first hydraulic push rod to move the pressure plate to the top of the inner cavity of the limiting component, place the right side of the explosion-proof protective film on the right side of the top of the equipment body, activate the first hydraulic push rod to move the pressure plate down until the right side of the explosion-proof protective film is pressed tightly. While the pressure plate moves, it will drive the first guide post to move up and down in the inner cavity of the limiting component. S2: Start the second servo motor to drive the threaded rod to rotate, so that the moving block on the front can be connected to it by the thread, thereby driving the roller to move down until it is attached to the top of the explosion-proof protective film. As the roller moves, it will drive the moving block on the back to move towards the bottom of the outer wall of the second guide post. S3: Start the first servo motor, which drives the threaded column to rotate in the inner cavity of the front movable slot, so that the front movable block can be connected with it by the thread, thereby driving the de-bubbling component to move left and right. At this time, the roller can roll on the top of the explosion-proof protective film, thereby performing de-bubbling work on the top of the explosion-proof protective film. S4: After degassing the top of the explosion-proof protective film, start the conveyor belt to transport the explosion-proof protective film to the left. At the same time, start the hydraulic lifting rod to lift the pressure plate. When the left side of the explosion-proof protective film moves to the adapter block, stop moving. Start the hydraulic lifting rod to press the pressure plate down. At the same time, start the second hydraulic push rod to drive the adapter block to rise. At this time, the adapter block and the pressure plate will clamp the left side of the explosion-proof protective film. S5: Start the electric slide rail, and the plastic scraper can be moved left and right by the electric slider. When the plastic scraper moves, it will push off the bottom of the pressure plate on the explosion-proof protective film. During the movement, the bottom of the film can be de-bubbled. At this time, the de-bubbling work on both sides of the explosion-proof protective film can be completed. S6: Remove the bolts to separate the plastic scraper from the reinforcing block, allowing it to be replaced or cleaned.

[0015] Beneficial effects Compared with the prior art, the present invention provides an explosion-proof protective film defoaming device and its defoaming process, which has the following beneficial effects: The explosion-proof protective film defoaming equipment and its defoaming process, by activating the first hydraulic push rod, can drive the pressure plate to press down, thus pressing down the right side of the top of the explosion-proof protective film. At the same time, the first guide column will be driven by the pressure plate to move at the limiting component, thereby ensuring the stability of the pressure plate movement. During the defoaming operation, it can limit the explosion-proof protective film and prevent it from moving randomly.

[0016] The explosion-proof protective film de-bubbling equipment and its de-bubbling process, by activating the second servo motor, can drive the threaded rod to rotate, so that the moving block on the front can be threadedly connected to it. This allows the height of the rollers to be adjusted according to the thickness of the explosion-proof protective film, so that it can fit tightly against the top of the explosion-proof protective film. After activating the first servo motor, the threaded column can be rotated, so that the moving block on the front can be threadedly connected to it. This drives the de-bubbling assembly equipped with rollers to move left and right, thereby performing the de-bubbling work on the top of the explosion-proof protective film.

[0017] The explosion-proof protective film defoaming equipment and its defoaming process, by activating the hydraulic lifting rod, can drive the pressure plate to move up and down, thereby providing support when defoaming the bottom of the explosion-proof protective film. By activating the second hydraulic push rod, the adapter block can be driven to rise, thereby matching the adapter groove to fix the right side of the explosion-proof protective film, facilitating subsequent defoaming work.

[0018] The explosion-proof protective film defoaming equipment and its defoaming process, by activating the set electric slide rail, allows the electric slider to drive the plastic scraper to move left and right through the reinforcing block, thereby performing defoaming work on the bottom of the explosion-proof protective film. At the same time, the set mounting block and bolts facilitate the disassembly and replacement of the plastic scraper. Attached Figure Description

A second guide post 15 is fixedly connected to the inner cavity of the rear moving groove 12. A front moving block 14 is threadedly connected to the outer wall of the moving block 14, and a rear moving block 14 is movably connected to the outer wall of the second guide post 15.

A first servo motor 9 is fixedly connected to the left side of the threaded post 8 via a second rotating shaft. The first servo motor 9 is fixedly connected to the top of the left front of the device body 1. The front and back of the bottom of the defoaming assembly 11 are symmetrically fixed... A movable block 10 is fixedly connected to the device body 1. Two movable blocks 10 are symmetrically and movably connected to the inner cavities of two movable slots 7. The front movable block 10 is threadedly connected to the outer wall of the threaded column 8.

[0023] By activating the first hydraulic push rod 4, the pressure plate 5 is pressed down, thus pressing down the right side of the top of the explosion-proof protective film. Simultaneously, the first guide post 6 is moved by the pressure plate 5 at the limiting component 3, ensuring the smooth movement of the pressure plate 5. This also limits the movement of the explosion-proof protective film during defoaming, preventing it from moving arbitrarily. Activating the second servo motor 17 rotates the threaded rod 16, allowing the front movable block 14 to connect with it.

Specific Implementation Example 2: like Figure 1-5 As shown, the defoaming process of an explosion-proof protective film defoaming device includes the following steps: S1: Activate the first hydraulic push rod 4 to move the pressure plate 5 to the top of the inner cavity of the limiting component 3, place the right side of the explosion-proof protective film on the right side of the top of the equipment body 1, activate the first hydraulic push rod 4 to move the pressure plate 5 down until the right side of the explosion-proof protective film is pressed tightly. While the pressure plate 5 moves, it will drive the first guide post 6 to move up and down in the inner cavity of the limiting component 3. S2: Start the second servo motor 17 to drive the threaded rod 16 to rotate, so that the front moving block 14 can be threadedly connected to it, thereby driving the roller 13 to move down until it is attached to the top of the explosion-proof protective film. While the roller 13 moves, it will drive the back moving block 14 to move towards the bottom of the outer wall of the second guide post 15. S3: Start the first servo motor 9, drive the threaded column 8 to rotate in the inner cavity of the front movable groove 7, so that the front movable block 10 can be threadedly connected to it, thereby driving the de-bubbling component 11 to move left and right. At this time, the roller 13 can roll on the top of the explosion-proof protective film, thereby de-bubbling the top of the explosion-proof protective film. S4: After degassing the top of the explosion-proof protective film, start the conveyor belt 18 to transport the explosion-proof protective film to the left.

Start the hydraulic lifting rod 20 to press down the pressure plate 19. At the same time, start the second hydraulic push rod 23 to drive the adapter block 22 to rise. At this time, the adapter block 22 and the pressure plate 19 will clamp the left side of the explosion-proof protective film. S5: Start the electric slide rail 26, and the electric slider 27 will drive the plastic scraper 25 to move left and right. When the plastic scraper 25 moves, it will push off the bottom of the pressure plate 19 on the explosion-proof protective film. When it moves, it can remove bubbles from the bottom. At this time, the bubble removal work on both sides of the explosion-proof protective film can be completed. S6: By removing bolt 30, the plastic scraper 25 can be separated from the reinforcing block 28, which can then be replaced or cleaned.
