The utility model includes a mounting frame, inside which two sets of adjustable shielding components are symmetrically arranged. Driving components are located at the top and bottom of the mounting frame, and are connected to the driving ends of the adjustable shielding components. This utility model guides the strip steel into the curing furnace between the two adjustable shielding components.

Description

Technical Field

[0001] This utility model belongs to the field of continuous strip coating technology, and specifically relates to an automatic adjustment device for furnace door sealing applied to a strip coating production line. Background Technology

[0002] In the strip steel coating production line, after the strip steel completes the coating process in the coating room, it needs to be transported to the curing oven for curing treatment. To ensure that the coated strip steel can continuously and smoothly enter the curing oven from the coating room, a rectangular slot structure is provided at the connection between the curing oven and the coating room. This slot design not only provides a passage for the movement of the strip steel, but also ensures the continuity of the production process, allowing the strip steel to enter the curing oven for subsequent processing in a timely manner without interruption.

[0003] The rectangular slot at the connection between the current curing oven and the coating room is relatively large, creating a significant gap between the oven and the strip during strip movement. This gap provides a channel for heat conduction and convection: on the one hand, under high-temperature conditions, heat inside the curing oven diffuses continuously to the lower-temperature external area through the gap via thermal convection, resulting in rapid heat loss from the oven; on the other hand, the temperature difference between the inside and outside of the oven promotes air convection, allowing cold air from outside to enter the oven through the gap, disrupting the stable temperature field inside the oven. This heat loss not only requires the curing oven to consume more energy to maintain the set temperature, significantly increasing production costs, but also causes temperature fluctuations within the oven, affecting the stability of the strip curing process and leading to inconsistent curing results, such as incomplete curing or over-curing. Utility Model Content

[0004] To address the problem that heat inside the curing oven can easily escape rapidly through the slots, this invention proposes an automatic adjustment device for the oven door seal in a strip steel coating production line, in order to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an automatic adjustment device for furnace door sealing applied to a strip steel coating production line. It includes a mounting frame, two sets of adjustable shielding components are symmetrically arranged inside the mounting frame, and driving components are provided at the top and bottom of the mounting frame. The driving components are connected to the driving end of the adjustable shielding components, and the shielding end of the adjustable shielding components is provided with a scraping component.

[0007] The driving component is used to drive the blocking end of the adjustable blocking component so that the distance between the two blocking ends can be adjusted. The scraping component moves synchronously at the blocking end so that the scraping component comes into contact with the surface of the steel strip.

[0008] Furthermore, the adjustable shielding component includes a storage frame, two of which are fixedly connected to the inner wall of the mounting frame. The slots of the two storage frames are arranged opposite each other. A plurality of adjusting screws are rotatably connected inside the storage frame, and an L-shaped shielding plate is threadedly connected to the outer surface of the plurality of adjusting screws. One end of the L-shaped shielding plate extends to the outside of the storage frame.

[0009] Furthermore, the drive assembly includes several driven bevel gears, one end of several adjusting screws passes through the mounting frame and is fixedly connected to the corresponding driven bevel gear, the outer surface of the driven bevel gear meshes with a driving bevel gear, a storage box is fixedly installed on the top of the mounting frame corresponding to the adjusting screw, a control rod is rotatably connected inside the storage box, the driving bevel gear is fixedly connected to the control rod, and the top and bottom of the mounting frame are set in the same way.

[0010] Furthermore, a mounting box is fixedly installed on one side of the mounting frame, and one end of the control rods provided at the top and bottom of the mounting frame extends into the interior of the mounting box. A sprocket is fixedly connected to the outer surface of the control rod, and the sprocket is located inside the mounting box. A chain is engaged on the outer surface of the sprocket. A drive motor is fixedly installed on the other side of the mounting frame, and the output end of the drive motor is fixedly connected to the control rod.

[0011] Furthermore, the scraping assembly includes an inclined scraper, which is fixedly connected to the front of the L-shaped baffle, and a cleaning plate is provided on the outer surface of the inclined scraper.

[0012] Furthermore, a support frame is fixedly installed on the outer side of the inclined scraper, and a drive screw is rotatably connected inside the support frame.

A cleaning motor is fixedly installed on the outer side of the support frame, and the output end of the cleaning motor is fixedly connected to the drive screw.

[0013] Furthermore, a mounting plate is fixedly connected to the back of the mounting frame, and mounting holes are provided on the front of the mounting plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model guides the strip steel into the curing oven between two adjustable shielding components. Then, a drive component drives the two sets of adjustable shielding components to move the two shielding ends synchronously toward the strip steel surface, thereby forming a small gap with the strip steel. The above setting allows the distance between the two shielding ends to be flexibly adjusted according to the thickness of the strip steel. At the same time, during the strip steel curing operation, it can effectively prevent the heat in the curing oven from rapidly escaping between the two shielding ends, thereby avoiding the phenomenon of incomplete curing of the strip steel due to temperature fluctuations in the oven.

[0016] 2. This utility model uses a drive motor to rotate a control lever. The rotating control lever drives an adjusting screw to rotate via a driving bevel gear and a driven bevel gear. At this time, the L-shaped baffle moves under the drive of the adjusting screw, and the inclined scraper moves downward synchronously under the drive of the L-shaped baffle, so that the inclined scraper can come into contact with the surface of the strip steel. This setting allows the inclined scraper to scrape off excess coating on the surface of the strip steel as it moves into the curing oven, so that the surface of the strip steel can remain flat when the coating is cured inside the curing oven, thereby ensuring the overall quality of the strip steel.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-6 As shown, this utility model is an automatic adjustment device for furnace door sealing applied to a strip steel coating production line, including a mounting frame 1. Two sets of adjustable shielding components 2 are symmetrically arranged inside the mounting frame 1. A drive component 3 is provided at the top and bottom of the mounting frame 1. The drive component 3 is connected to the drive end of the adjustable shielding component 2. A scraping component 4 is provided at the shielding end of the adjustable shielding component 2.

[0030] The driving component 3 is used to drive the blocking end of the adjustable blocking component 2 so that the distance between the two blocking ends can be adjusted. The scraping component 4 moves synchronously at the blocking end so that the scraping component 4 comes into contact with the surface of the steel strip.

[0031] By installing the mounting frame 1 in the slot of the curing oven, the steel strip is guided into the interior of the curing oven between the two adjustable shielding components 2. Then, the two sets of adjustable shielding components 2 are driven by the drive component 3, so that the two shielding ends move simultaneously to the middle position of the mounting frame 1, and the distance between the two shielding ends is adjusted according to the thickness of the steel strip. At the same time, the scraping end of the scraping component 4 comes into contact with the surface of the steel strip under the drive of the shielding end.

[0032] After the strip steel is guided into the interior of the curing oven between the two adjustable shielding components 2, the two sets of adjustable shielding components 2 are driven by the drive component 3, so that the two shielding ends move synchronously toward the surface of the strip steel, thereby forming a small gap with the strip steel. The above setting allows the distance between the two shielding ends to be flexibly adjusted according to the thickness of the strip steel. At the same time, during the strip steel curing operation, it can effectively prevent the heat in the curing oven from being lost rapidly between the two shielding ends, thereby avoiding the phenomenon of incomplete curing of the strip steel due to temperature fluctuations in the oven.

[0033] In one embodiment, the adjustable shielding component 2 includes a storage frame 201. Two storage frames 201 are fixedly connected to the inner wall of the mounting frame 1. The slots of the two storage frames 201 are arranged opposite each other. A plurality of adjusting screws 202 are rotatably connected inside the storage frame 201. An L-shaped shielding plate 203 is threadedly connected to the outer surface of the plurality of adjusting screws 202. One end of the L-shaped shielding plate 203 extends to the outside of the storage frame 201.

[0034] By rotating the adjusting screws 202 inside the two storage frames 201, the rotating adjusting screws 202 can drive the corresponding L-shaped baffles 203 to move out of the storage frames 201 continuously, thereby adjusting the distance between the two L-shaped baffles 203. This setting makes it less likely for a large amount of heat to escape from the slots of the curing oven, while also allowing for adjustment according to the width of strip steel of different specifications.

[0035] In one embodiment, the drive assembly 3 includes a plurality of driven bevel gears 301, one end of a plurality of adjusting screws 202 passing through the mounting frame 1 and fixedly connected to the corresponding driven bevel gear 301, the outer surface of the driven bevel gear 301 meshing with the driving bevel gear 302, a storage box 303 fixedly mounted on the top of the mounting frame 1 corresponding to the adjusting screw 202, a control rod 304 rotatably connected inside the storage box 303, the driving bevel gear 302 and the control rod 304 fixedly connected together, and the top and bottom of the mounting frame 1 are set in the same way.

[0036] By rotating the control lever 304, the rotating control lever 304 can drive multiple active bevel gears 302 to drive the corresponding driven bevel gears 301 to rotate. The rotating driven bevel gears 301 can drive the corresponding adjusting screws 202 to rotate. The above arrangement allows multiple adjusting screws 202 inside a storage frame 201 to rotate synchronously under the drive of a control lever 304. At this time, multiple adjusting screws 202 can simultaneously drive the same L-shaped baffle 203, thereby further improving the stability of the L-shaped baffle 203 when it moves.

[0037] In one embodiment, for the aforementioned mounting frame 1, a mounting box 305 is fixedly mounted on one side of the mounting frame 1. One end of a control rod 304 provided at the top and bottom of the mounting frame 1 extends into the interior of the mounting box 305. A sprocket 306 is fixedly connected to the outer surface of the control rod 304. The sprocket 306 is located inside the mounting box 305, and a chain 307 is engaged on the outer surface of the sprocket 306. A drive motor 308 is fixedly mounted on the other side of the mounting frame 1, and the output end of the drive motor 308 is fixedly connected to the control rod 304.

[0038] One of the control levers 304 is rotated by a drive motor 308, and the rotating control lever 304 drives the other control lever 304 to rotate simultaneously via a sprocket 306 and a chain 307. This configuration allows only one drive motor 308 to drive the adjusting screws 202 inside the two storage frames 201 to rotate synchronously. At the same time, the two L-shaped baffles 203 inside the two storage frames 201 can move out simultaneously, thereby making the baffle range symmetrical and balanced, thus improving the stability and reliability of the equipment operation.

[0039] In one embodiment, the scraping component 4 includes an inclined scraper 401, which is fixedly connected to the front of the L-shaped baffle 203, and a cleaning plate 402 is provided on the outer surface of the inclined scraper 401.

[0040] The inclined scraper 401 moves downwards synchronously under the action of the L-shaped baffle 203, allowing it to contact the surface of the strip. This arrangement enables the inclined scraper 401 to scrape away excess coating as the strip moves into the curing oven, ensuring a smooth surface and consistent overall quality during coating curing. Furthermore, in practice, the cleaning plate 402 can be made of silicon-based material, allowing it to push the coating on the inclined scraper 401 away from the surface. The material does not easily adhere to the cleaning plate 402; the cleaning plate 402 can move on the surface of the inclined scraper 401, and the moving cleaning plate 402 can push the cleaned paint off the inclined scraper 401, thereby avoiding the accumulation of paint on the surface of the inclined scraper 401, and ensuring the scraping effect of the inclined scraper 401; the bottom of the inclined scraper 401 and the bottom of the L-shaped baffle 203 are on the same horizontal plane, so that the inclined scraper 401 can scrape off the excess paint on the strip surface at an angle, and the gap between the two L-shaped baffles 203 and the strip is small.

[0041] In one embodiment, for the inclined scraper 401, a support frame 403 is fixedly installed on the outer side of the inclined scraper 401, a drive screw 404 is rotatably connected inside the support frame 403, the drive screw 404 is threadedly connected to the cleaning plate 402, a guide rod 405 is fixedly connected inside the support frame 403, the cleaning plate 402 is movably connected to the guide rod 405, and a cleaning motor 406 is fixedly installed on the outer side of the support frame 403, the output end of the cleaning motor 406 is fixedly connected to the drive screw 404.

[0042] The cleaning motor 406 drives the drive screw 404. At this time, the cleaning plate 402 can move along the surface of the inclined scraper 401 under the drive of the drive screw 404 and the guidance of the guide rod 405. This allows the cleaning plate 402 to automatically push the paint scraped off the inclined scraper 401 and push the paint off the inclined scraper 401.

[0043] In one embodiment, for the aforementioned mounting frame 1, a mounting plate 5 is fixedly connected to the back of the mounting frame 1, and a mounting hole 6 is provided on the front of the mounting plate 5.

[0044] The mounting plate 5 can be fixed to the slot of the curing oven by the fixing bolts. At this time, the mounting frame 1 can be directly placed in the slot under the support of the mounting plate 5. With the assistance of the mounting plate 5, the mounting frame 1 can be precisely in contact with the curing oven, so that the sealing of the connection between the two can be guaranteed.

[0045] Through the above technical solution, 1. After the strip steel is guided into the curing oven between the two adjustable shielding components 2, the two sets of adjustable shielding components 2 are driven by the drive component 3, so that the two shielding ends move synchronously towards the surface of the strip steel, thereby forming a small gap with the strip steel; the above setting allows the distance between the two shielding ends to be flexibly adjusted according to the thickness of the strip steel, and at the same time, during the strip steel curing operation, it can effectively prevent the rapid loss of heat from the two shielding ends in the curing oven, thereby avoiding the phenomenon of incomplete curing of the strip steel due to temperature fluctuations in the oven; 2. The control lever 304 is rotated by the drive motor 308, and the rotating control lever 304 The adjusting screw 202 is rotated by the driving bevel gear 302 and the driven bevel gear 301. At this time, the L-shaped baffle 203 moves under the drive of the adjusting screw 202, and the inclined scraper 401 moves downward synchronously under the drive of the L-shaped baffle 203, so that the inclined scraper 401 can come into contact with the surface of the strip. This setting allows the inclined scraper 401 to scrape off the excess coating on the surface of the strip as it moves into the curing oven, so that the surface of the strip can remain flat when the coating is cured in the curing oven, thus ensuring the overall quality of the strip.
