Description

Technical Field

[0001] This invention relates to the field of ceramic fiber refractory insulation board cutting technology, specifically a dust removal cutting device for a ceramic fiber refractory insulation board production line. Background Technology

[0002] Ceramic fiber fire-resistant insulation board is a lightweight, high-temperature resistant, and low-thermal-conductivity rigid fire-resistant insulation material. It is made of aluminosilicate fibers and inorganic binders through vacuum forming or dry pressing, and is widely used in industrial high-temperature equipment and building fireproofing and insulation.

[0003] For a thin-plate slitting process of a ceramic fiber refractory insulation board, during the cutting process, a single board is slid into multiple thin plates. The cutting surfaces of these thin plates contain fine dust generated during cutting, requiring the removal of dust adhering to both sides of each layer during subsequent processing. Furthermore, the cutter needs to be returned to its original position before a second cut can be made. These defects not only easily reduce the efficiency of the cutting process but also cause continuous dust dispersion in the production environment, which is detrimental to environmental protection. To address these issues, we propose a dust-removing cutter device for a ceramic fiber refractory insulation board production line. Summary of the Invention

[0010] Preferably, an upper swing arm is hinged to the top center of the lower swing arm relative to one side of the flat base. The middle two sides of the upper swing arm intermittently abut against the stop shaft. A tension spring is connected to the top center of the upper swing arm and the bottom center of the lower swing arm. A through hole is provided on the platform below the lower swing arm.

[0017] In this invention, by means of a top support mechanism, when a gap is cut into the plate, the plug is released into the gap according to the trigger mechanism. At the same time, combined with the airbag and airway, gas is blown out from the end of the plug, which facilitates the top support operation. According to the top support operation, the rear end of the plate sheet cut above is supported, which makes it easier for the powder extraction mechanism to enter.

[0018] In this invention, a powder extraction mechanism is used to extract powder between the sheet metal and the main body of the sheet metal, improving the efficiency of the entire cutting process and preventing dust from being dispersed in the air during subsequent powder removal. A switching mechanism is also used to switch the positions of the two powder extraction mechanisms when the moving frame moves to the edge of the machine, so that the device does not need to return to its original position. After the cutting of one sheet metal is completed, the height of the band saw is directly reduced to cut the second sheet metal, further improving the cutting efficiency. Attached Figure Description

A plug 703 is fixedly connected to the end face of the movable seat 702. The plug 703 is arranged in a sloping structure. An air passage 704 is provided through the interior of the plug 703.

[0050] A boom 705 is slidably mounted on the movable base 702. A roller 706 is rotatably mounted at the bottom center of the boom 705. The surface of the roller 706 abuts against the first pitch bar 401 and the first insert bar 403 respectively. An airbag 707 is connected to the side of the roller 706 on the boom 705.

The end of the air tube 708 away from the airbag 707 is connected to the air passage 704 through the plug 703. A clip 709 is installed on the outer edge of the air tube 708. The clip 709 is fixedly connected to the top side of the movable base 702.

[0051] In this embodiment, before the cutting begins, the ceramic fiber plate to be cut is placed at the center of the surface of the machine 100. At this time, the distance between the two limiting plates 402 in the triggering mechanism 400 is adjusted so that the limiting plates 402 fit the edge of the plate to be cut.

[0052] In this embodiment, in the initial state, the airbag 707 is located in the wide area between the second pitch bar 404 and the platform 306, and the airbag 707 is in a fully inflated state. The outer surface of the airbag 707 is provided with an anti-wear layer at the part that contacts the second pitch bar 404 and the platform 306. The roller 706 continuously abuts against the surface of the first pitch bar 401. A telescopic tube is provided at the connection between the airbag 707 and the boom 705 to prevent the airbag 707 from being dragged when the boom 705 moves laterally. Before cutting, the band saw 304 is lowered by the height adjustment mechanism 305. The band saw 304 is aligned with the side of the plate for cutting. The drive slide rail 200 is started to control the moving frame 301 to slide to the other side along the length of the machine table 100. The airbag 707 follows the movement. When in motion, the blade moves from the wide opening between the second variable-pitch strip 404 and the machine base 100 to the narrow opening. During this process, the airbag 707 is first compressed, and the gas inside the airbag 707 is introduced into the air passage 704 through the air pipe 708 and blown out from the port of the plug 703. This blows air onto the piece of board being cut above the cutting part of the band saw 304, causing the upper board to be blown up. At the same time, the roller 706 moves with the moving frame 301 from the curved part of the first variable-pitch saw blade to the straight part, causing the spring on the spring frame to be gradually released. The tip of the plug 703 moves towards the board and, with the assistance of the airbag 707 blowing up, the plug 703 is inserted into the gap between the lower and upper boards and supports the upper board, facilitating the cutting and powder extraction operation.

[0053] In this embodiment, initially, when a slit is horizontally cut into the top of the entire board, the plug 703 is preferentially inserted into the slit, causing the portion of the entire board above the slit to be supported. Subsequently, the mounting bracket 501 in the powder extraction mechanism 500... Figure 8As shown, following the movement, the lower frame 502 extends into the gap supported by the plug 703. The power mechanism 505 and the exhaust fan 506 are turned on in advance. The upper and lower sides of the two powder-dispensing rollers 503 contact the top and bottom of the gap in the board to sweep away the cutting dust attached to the board. The dust is sucked into the exhaust fan 506 through the cavity 504 for filtration and collection. At the same time, the upper frame 502 is suspended and moved above the board to assist in absorbing the cutting dust dispersed in the air.

[0054] In this embodiment, as the moving frame 301 moves forward, a cutting operation is completed, cutting off a thin plate from the top of the entire board. The cutting dust between the thin plate and the entire board is absorbed. At this time, the moving frame 301 continues to move forward. During the process, the airbag 707 moves from the narrow part of the second pitch bar 404 and the platform 306 to the wide part. The compressed airbag 707 automatically inflates to prepare for the return second cutting. At the same time, the roller 706 moves again from the straight part of the first pitch bar 401 to the curved part, causing the two plugs 703 to retract outward.

[0055] In this embodiment, as described above, synchronously, the extension arm 613, which is close to a side plate 406, is blocked by the side plate 406 during its movement, causing the extension arm 613 to drive the horizontal plate 611 to undergo relative displacement with the platform 306. The horizontal plate 611 compresses the elastic element 610, and the two inclined wedges 612 connected to the horizontal plate 611 press... Figure 9 As shown, the trigger arm 608, located inside the two upper swing arms 605, is squeezed and pushed. The bottom of the upper swing arm 605 rotates to the other side around its hinge with the lower swing arm 601. During this process, the tension spring 606 is briefly stretched, simultaneously causing the lower swing arm 601 to swing synchronously in the direction of the upper swing arm 605. Then, the pushing operation of the extension arm 613 ends, the tension spring 606 rebounds, and the upper swing arm 605 and the lower swing arm 601 switch to... Figure 9 On the other side of the direction shown, during the process, the lower swing arm 601 rotates to switch the two dust extraction mechanisms 500. The dust extraction mechanism 500 that previously performed dust removal from the board cutting gap is switched to the upper position, and the dust extraction mechanism 500 that previously performed dust suction above the board is switched to the lower position to perform dust removal from the board cutting gap. Then, the drive slide rail 200 drives the moving frame 301 to move in the opposite direction to perform the cutting operation again.

[0056] In this embodiment, the height adjustment mechanism 305 is preferably a screw motor structure, which is well known in the art and will not be described in detail here. The elastic element 610 is preferably a spring structure, and the powder-dispensing roller 503 is preferably a brush structure.

[0057] The method of use and advantages of this invention: The dust removal and cutting device for a ceramic fiber refractory insulation board production line works as follows:

[0058] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown:

[0059] S1: Before cutting, place the ceramic fiber board in the center of the machine 100 and adjust the spacing of the limiting plate 402 to make it fit the edge of the board;

[0060] S2: In the initial state of the equipment, the airbag 707 is in the inflated position, the roller 706 abuts against the first pitch bar 401, the band saw 304 is lowered to align with the side of the plate, and the moving frame 301 is driven to slide. During the movement, the airbag 707 is compressed, and the gas is blown out through the pipeline to blow up the upper plate. At the same time, the elastic element 610 of the spring rod 701 is gradually released, and the plug 703 is inserted into the gap of the plate to support and lift the upper plate, leaving space for dust removal operation.

[0061] S3: After the gap is cut into the board, the plug 703 supports the area above the gap, the dust extraction mechanism 500 moves with the equipment, the lower frame 502 extends into the gap to clean and absorb dust, and the upper frame 502 simultaneously sucks up the scattered dust.

[0062] S4: After a single cut is completed, the moving frame 301 continues to move forward, the airbag 707 resets and inflates, the plug 703 retracts synchronously, and the equipment resets to prepare for the return cut.

[0063] S5: When the moving frame 301 moves towards the end, the extension arm 613 is blocked by the side plate 406, which drives the inclined wedge head 612 to push the swing arm to rotate, completing the exchange of the upper and lower positions of the two powder extraction mechanisms 500. After that, the moving frame 301 slides in the opposite direction to carry out the secondary cutting operation.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
