Description

Technical Field

[0001] This utility model relates to the field of sealing blanket cutting technology, specifically a sealing blanket cutting device for carbon block roasting furnace. Background Technology

[0002] Sealing blankets are a commonly used sealing structure in carbon block roasting furnaces. They typically use ceramic fiber blankets or ceramic fiber blocks to fill and seal the gaps between the furnace tubes and the furnace top plate. They offer advantages such as good sealing performance, high temperature resistance, long service life, and relatively low maintenance costs. Furthermore, ceramic fiber blankets are lightweight and easy to install, allowing for layering, wrapping, bundling, bonding, and anchoring.

[0003] In the existing technology, electric cutting machines are generally used to cut sealing blankets. However, if there is a lack of measures to flatten and compact the sealing blanket during the cutting process, the sealing blanket may wrinkle, which can easily affect the cutting quality of the sealing blanket. In addition, a large amount of lint will be generated during the cutting process. If there is a lack of measures to deal with the lint in a timely manner, it will not only affect the cutting environment, but also make the collection and disposal of lint inconvenient.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a sealing blanket cutting device for a carbon block roasting furnace, including a cutting frame 1 and a cutting table 2. The cutting table 2 is fixed to the bottom of the cutting frame 1. A first sliding frame 4 is provided above the cutting table 2. An electric cylinder 15 is fixed to the middle of the lower end of the first sliding frame 4. A lifting platform 8 is connected to the power end of the electric cylinder 15. An electric cutting machine 9 is installed at the middle of the lower end of the lifting platform 8. Lifting blocks 13 are provided on both the left and right sides of the upper end of the lifting platform 8. A return spring 14 is connected between each lifting block 13 and the lifting platform 8. A lifting plate 10 is fixed to the lower end of each lifting block 13. The lifting plate 10 slides through the lifting platform 8. A pressure roller 12 is rotatably connected to the lower end of each lifting plate 10. A laser positioning head 11 is connected to the outer side of each lifting plate 10.

[0021] When the sealing blanket is cut using this cutting device, the sealing blanket is fixed on the cutting table 2. The light spots emitted by the two laser positioning heads 11 are directed onto the sealing blanket. The two light spots form a line, which helps to accurately determine the cutting position of the sealing blanket and achieve the effect of precise cutting.

[0022] In this embodiment, a recessed rail 3 is provided above the cutting frame 1. A first forward and reverse motor 5 is fixed to the left end of the recessed rail 3. The power end of the first forward and reverse motor 5 is connected to a first lead screw 6. The end of the first lead screw 6 is rotatably connected to the right end of the recessed rail 3. A first sliding frame 4 is slidably connected to the recessed rail 3, and the first sliding frame 4 is threadedly sleeved with the first lead screw 6. A rotating shaft 24 is fixed to the middle of the upper end of the recessed rail 3. A second sliding frame 19 is rotatably connected to the upper end of the rotating shaft 24. The second sliding frame 19 is slidably connected to the cutting frame. At the top of the inner side of the cutting frame 1, a second forward and reverse motor 20 is fixed to the upper left end. The power end of the second forward and reverse motor 20 is connected to a second lead screw 21, and the end of the second lead screw 21 is rotatably connected to the right end of the cutting frame 1. The second sliding frame 19 is threadedly connected to the second lead screw 21. A brake motor 22 is fixed to the lower end of the second sliding frame 19. The power end of the brake motor 22 is connected to a main gear 23. A secondary gear 25 is fixedly sleeved around the rotating shaft 24. The main gear 23 and the secondary gear 25 mesh.

[0023] When the cutting position of the electric cutting machine 9 needs to be adjusted, the operation of the first forward and reverse motor 5 drives the first lead screw 6 to rotate. The first lead screw 6 drives the first sliding frame 4 to slide back and forth along the concave rail 3. Therefore, the first sliding frame 4 drives the electric cylinder 15, the lifting platform 8, and the electric cutting machine 9 to move back and forth together, thereby facilitating the adjustment of the cutting position of the electric cutting machine 9. Furthermore, the operation of the brake motor 22 drives the main gear 23, the secondary gear 25, the rotating shaft 24, the concave rail 3, the first sliding frame 4, and the electric cutting machine 9 to rotate. Therefore, it is beneficial to adjust the cutting angle of the electric cutting machine 9. Combined with the second forward and reverse motor 20 driving the second lead screw 21 to rotate, it is beneficial to drive the second sliding frame 19 to move back and forth along the cutting frame 1. The second sliding frame 19 will drive the rotating shaft 24, the concave rail 3 and the electric cutting machine 9 to move together. Therefore, it is beneficial to continue to change the cutting position of the electric cutting machine 9. In summary, it is beneficial to flexibly change the cutting position of the electric cutting machine 9 according to the cutting position of the sealing blanket, and it is also beneficial to carry out moving cutting, effectively ensuring the cutting effect of the sealing blanket.

[0024] In this embodiment, lifting blocks 13 are provided on both the left and right sides of the upper end of the lifting platform 8. Each lifting block 13 is connected to the lifting platform 8 by a return spring 14. Each lifting block 13 is fixed with a lifting plate 10 at its lower end. Each lifting plate 10 slides through the lifting platform 8. Each lifting plate 10 is rotatably connected to a pressure roller 12 at its lower end. The initial distance between the pressure roller 12 and the cutting table 2 is smaller than the initial distance between the electric cutting machine 9 and the cutting table 2.

[0025] Furthermore, the extension of the electric cylinder 15 drives the lifting platform 8, the electric cutting machine 9, and the pressure roller 12 to move downwards. The pressure roller 12 first presses down on the sealing blanket. During this process, the lifting plate 10 pushes up the lifting block 13, so the return spring 14 is stretched by the lifting block 13. Then, the electric cutting machine 9 cuts the sealing blanket on the cutting table 2. When the electric cutting machine 9 moves to cut, the pressure roller 12 simultaneously compacts and flattens the sealing blanket, which helps to prevent wrinkles from occurring during the cutting process and thus helps to ensure the cutting quality of the sealing blanket.

[0026] In this embodiment, vacuum cleaners 7 are fixed on both the left and right sides of the lower end of the first sliding frame 4. The suction ports of the vacuum cleaners 7 are connected to telescopic tubes 16. The electric cutting machine 9 is provided with suction pipes 17 on both the left and right ends. The lower ends of the suction pipes 17 are connected to suction hoods 18, and the suction pipes 17 are fixedly extended through the lifting platform 8. The lower ends of the telescopic tubes 16 are connected to the suction pipes 17 on the same side.

[0027] When the sealing blanket is cut by the electric cutting machine 9, the vacuum cleaner 7 is started at the same time. The dust hood 18 is used to absorb the lint generated during the cutting in time. The lint is then absorbed into the vacuum cleaner 7 through the suction pipe 17 and the telescopic pipe 16, which helps to reduce the impact of lint on the cutting environment and effectively reduces the trouble of collecting lint later. In addition, when the electric cylinder 15 drives the lifting platform 8 to move up and down, it will stretch or compress the telescopic pipe 16, which helps to ensure the normal up and down movement of the lifting platform 8.

[0028] Working principle;

[0029] Two laser positioning heads 11 emit light spots onto the sealing blanket, forming a line between them to determine the cutting position. The electric cylinder 15 extends, causing the lifting platform 8, electric cutting machine 9, and pressure roller 12 to move downwards. The pressure roller 12 first presses down on the sealing blanket. During this process, the lifting plate 10 pushes up the lifting block 13, stretching the return spring 14. Then, the electric cutting machine 9 cuts the sealing blanket on the cutting table 2. As the electric cutting machine 9 moves to cut, the pressure roller 12 simultaneously compacts and flattens the sealing blanket. At the same time, the vacuum cleaner 7 starts, and the vacuum hood 18 effectively absorbs the lint generated during cutting. Finally, the lint is absorbed into the vacuum cleaner 7 through the vacuum pipe 17 and the telescopic pipe 16.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
