Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite board production technology, and more specifically, it relates to an intumescent fireproof composite board cutting device. Background Technology
[0002] Composite boards are boards made of a combination of multiple materials, possessing the functional characteristics of various materials and meeting diverse usage needs. In environments such as office buildings and residences, where there are a large number of people, there is a high demand for fire protection. Intumescent fireproof boards have excellent fire resistance, thus there is a growing demand for intumescent fireproof composite boards.
[0003] When producing intumescent fire-resistant composite panels, it is necessary to cut the panels into appropriate sizes to meet different application requirements. However, common cutting equipment generally only consists of a cutting machine and related support structures. Workers need to manually push the panels to contact the cutter for cutting. During this process, workers need to pick up the composite panels one by one and control the entire process, resulting in a large workload and low cutting efficiency. Moreover, during cutting, the contact between the cutter and the composite panel generates a large amount of debris. This debris is splashed around by the cutter, filling the cutting environment with panel debris and polluting the surrounding environment. The large accumulation of debris around the cutter can easily affect the cutting operation. Workers are directly next to the equipment and are easily affected by the debris. In addition, when workers control the panels to cut, the movement of the panels is done by pushing them with their hands. The cutting accuracy depends entirely on the worker's skill. With a large workload, workers' concentration may be low, leading to errors such as shaky hands and inaccurate positioning, affecting the cutting quality. Utility Model Content

[0016] (III) Beneficial Effects
[0017] Compared with the prior art, this utility model provides an intumescent fireproof composite board cutting device, which has the following beneficial effects:
[0018] 1. The machine uses a frame, conveyor belt, and cutter to transport and cut the boards. Power is provided by the cooperation of support frame, push cylinder, push frame, pressure cylinder, and pressure frame. The pressure plate and push plate make contact with the intumescent fireproof composite board to be cut, ensuring stable cutting of the composite board in conjunction with the cutter. The whole process is automated, eliminating reliance on workers, reducing their workload, and improving work efficiency.
[0019] 2. The cutting area is covered by a shielding cover, leaving only the front and rear ends for the composite board to pass through. The shielding cover provides a blocking effect to prevent the flying of debris generated during cutting. At the same time, the air intake fan and exhaust fan work together to form an air duct to blow away the debris in the cutting area.

[0030] See also Figure 1-5 An intumescent fireproof composite board cutting device includes a frame 1, a conveyor belt 2 at one end of the frame 1 and a cutting table 3 at the other end, a cutter 4 on the cutting table 3, a support frame 5 at one end of the frame 1 and a push cylinder 6 on the support frame 5, a push frame 7 at the output end of the push cylinder 6, pressure cylinders 8 at both ends of the push frame 7, a pressure frame 9 at the output end of the pressure cylinders 8, a pressure plate 10 at the lower end of the pressure frame 9, and a push plate 11 at the side end of the pressure plate 10.
[0031] The support frame 5 is equipped with a shield 12 at its lower end. One end of the shield 12 is equipped with an air inlet fan 13, and the other end of the shield 12 is equipped with a dust collection pipe 14. The cutting table 3 is provided with a cutting opening 15, which is matched with the cutter 4. The lower end of the cutting opening 15 is equipped with a dust collection box 16, and the cutting opening 15 is connected to the inside of the dust collection box 16. The lower end of the dust collection pipe 14 is connected to the dust collection box 16. The side end of the dust collection box 16 is equipped with an exhaust fan 17, and a dust filter screen 18 is provided at the connection between the dust collection box 16 and the exhaust fan 17.
[0032] In this embodiment, the intumescent fireproof composite board to be cut is placed on the conveyor belt 2 by the support device of the frame 1. The conveyor belt 2 transports the intumescent fireproof composite board to the cutting table 3. At this time, under the support of the support frame 5, the pressure cylinder 8 is controlled to move the pressure frame 9 downward. The pressure plate 10 and the push plate 11 come into contact with the intumescent fireproof composite board. The pressure plate 10 presses down on the upper end of the intumescent fireproof composite board, and the push plate 11 abuts against the side end of the intumescent fireproof composite board. Then, the push cylinder 6 is activated to control the movement of the push frame 7, thereby driving the pressure frame 9 to move. Under the push of the push plate 11, the intumescent fireproof composite board moves towards the cutter 4, and the cutting of the intumescent fireproof composite board remains stable under the pressure of the pressure plate 10.
[0033] More specifically, supported by the support frame 5, the cutting area is covered by the shield 12. When cutting, the air intake fan 13 is activated to draw airflow from the outside into the shield 12 and blow it onto the processing area, blowing the debris generated during cutting to the other end. The debris is then collected by the dust collection pipe 14 and the exhaust fan 17 is activated to create a negative pressure for extraction. This, in conjunction with the air intake fan 13, forms an air duct, causing the debris in the working area to move into the dust collection pipe 14. The debris is then collected by the dust collection box 16, and the dust filter 18 intercepts the debris in the dust collection box 16 to prevent it from flying out.
[0034] See also Figure 1 and Figure 2 As one embodiment of the position guidance: the frame 1 is provided with guide frames 19 at both ends. The guide frame 19 includes a guide inclined frame 20 and a limiting straight frame 21. The guide frame 19 is provided on the side near the conveyor belt 2, and the limiting straight frame 21 is provided on the side near the cutting table 3.
[0035] Specifically, during the transport of composite panels, they are guided by guide frame 19. If the composite panel placed on the conveyor belt 2 is in an skewed state, it will come into contact with guide frame 20 during movement. With the restriction and guidance of guide frame 20, the composite panel is gradually straightened and enters the restricting straight frame 21. When cutting on the cutting table 3, the two ends are restricted by the restricting straight frame 21 to ensure the cutting stability of the composite panel.
[0036] See also Figure 1 As a further implementation of the position guidance: the frame 1 is provided with support frames 22 at both ends, and the outer end of the support frame 22 is provided with an adjusting push rod 23, the output end of the adjusting push rod 23 is engaged with the guide frame 19.
[0037] Specifically, the support frame 22 maintains stability, and the operation of the adjusting push rod 23 is controlled to adjust the position of the guide frame 19 to adapt to composite panels of different widths. Furthermore, by controlling the adjusting push rods 23 at both ends to extend to different degrees, the cutting position of the composite panel can also be adjusted.
[0038] See also Figure 2 As a further implementation of the position guidance: a limiting frame 24 is provided on the guide frame 19, and a limiting roller 25 is rotatably connected to the limiting frame 24.
[0039] Specifically, the limit frame 24 provides an additional structure to support the limit roller 25. When guiding the composite board, the limit roller 25 contacts the composite board and can rotate freely, reducing friction generated when restricting the composite board and ensuring stable transportation of the composite board.
[0040] See also Figure 5 As a further embodiment of the limiting frame: the limiting frame 24 is provided with a rotating shaft 26, the limiting roller 25 is rotatably engaged with the rotating shaft 26, the lower end of the rotating shaft 26 is rotatably connected with a support block 27, the lower end of the limiting roller 25 is provided with a storage groove 28, and the support block 27 is engaged with the storage groove 28.
[0041] Specifically, the limiting frame 24 supports the limiting roller 25 through the cooperation of the rotating shaft 26 and the support block 27. The support block 27 is inserted into the lower end of the limiting roller 25 from the receiving groove 28, reducing the distance between the limiting roller 25 and the surface of the conveyor belt 2, and preventing the limiting roller 25 from being too high to accommodate the thinner composite board.
[0042] See also Figure 3 As a further embodiment of the pressure plate: both the pressure plate 10 and the push plate 11 are provided with protective pads 29 on their inner sides.
[0043] Specifically, both the pressure plate 10 and the push plate 11 are in contact with the surface of the composite board through the protective pad 29. When pressure is applied, the pressure is distributed more evenly and provides a certain buffer protection to avoid damage to the composite board caused by excessive pressure.
[0044] See also Figure 3 As a further embodiment of the support frame: the support frame 5 is provided with a sliding hole 30, and the pressure frame 9 is slidably engaged with the sliding hole 30.
[0045] Specifically, when the pusher 7 moves the pressure plate 9, space is provided through the sliding hole 30, allowing the pressure plate 9 to move along the movable hole, thereby allowing the pressure plate 9 to pass through the support frame 5 and control the movement of the internal pressure plate 10 and pusher plate 11.
[0046] See also Figure 1 and Figure 3 As a further embodiment of the support frame: the pressure frame 9 is provided with a cover plate 31 on the side end, and the cover plate 31 cooperates with the sliding hole 30.
[0047] Specifically, when the pressure frame 9 moves, it will cause the sliding holes 30 at both ends to move. The sliding holes 30 will block the movable hole to prevent debris from flying out of the movable hole during cutting.
[0048] In summary, when the entire device is in use (or running):
[0049] When using the equipment, connect the electrical components to an external power source. The equipment is supported by frame 1. The intumescent fireproof composite panels to be cut are placed sequentially onto conveyor belt 2. Only simple directional adjustments are needed during placement to ensure the cutting surface faces the cutter 4, preventing excessive deflection. The conveyor belt 2 transports the intumescent fireproof composite panel box cutting table 3. During this movement, the composite panels are guided by guide frame 19. If a composite panel placed on conveyor belt 2 is tilted, it will contact guide frame 20 during movement. Guide frame 20 restricts and guides the composite panel, gradually straightening it and guiding it into the limiting straight frame 21. Under the constraint of the limiting straight frame 21, it maintains stable movement. The limiting frame 24 provides additional support for the limiting rollers. 25. When guiding the composite board, the limiting roller 25 contacts the composite board and can rotate freely, reducing friction caused by restricting the composite board and ensuring stable transport of the composite board. In addition, the limiting frame 24 supports the limiting roller 25 through the cooperation of the rotating shaft 26 and the support block 27. The support block 27 is inserted into the lower end of the limiting roller 25 from the receiving groove 28, reducing the distance between the limiting roller 25 and the surface of the conveyor belt 2, and preventing the limiting roller 25 from being too high to accommodate thinner composite boards. Moreover, when facing composite boards of different widths, the support frame 22 maintains stability, and the control adjustment push rod 23 is used to adjust the position of the guide frame 19 to adapt to composite boards of different widths. Furthermore, by controlling the adjustment push rods 23 at both ends to extend to different degrees, the cutting position of the composite board can also be adjusted.
[0050] After the intumescent fireproof composite board to be cut is moved onto the cutting table 3, supported by the support frame 5, the pressure cylinder 8 is controlled to move the pressure frame 9 downwards, causing the pressure plate 10 and the push plate 11 to move. The pressure plate 10 presses down on the upper part of the intumescent fireproof composite board, and the push plate 11 moves close to the side of the composite board. Then, the push cylinder 6 is activated to move the push frame 7, thereby moving the pressure frame 9. Space is provided through the sliding hole 30, allowing the pressure frame 9 to move along the movable hole, thus allowing the pressure frame 9 to pass through the support frame 5. The internal pressure plate 10 and push plate 11 are controlled to move, so that the pressure frame 9, along with the push plate 11, presses against the intumescent fireproof composite board. The fire-resistant composite panel is moved to the side, and then the cylinder 6 is pushed to continue working, thereby driving the pressure plate 10 and the push plate 11 to continue moving. Under the push of the push plate 11, the fire-resistant composite panel moves towards the cutter 4 for cutting. Under the pressure of the pressure plate 10, the cutting of the fire-resistant composite panel remains stable. In addition, both the pressure plate 10 and the push plate 11 are in contact with the surface of the composite panel through the protective pad 29. When applying pressure, the pressure is distributed more evenly and provides a certain buffer protection to avoid damage to the composite panel due to excessive pressure. When cutting on the cutting table 3, the two ends are restricted by the limiting straight frame 21 to ensure the cutting stability of the composite panel.
[0051] When the composite board is being cut, the shield 12 covers the cutting area with the support frame 5. During the cutting process, the air intake fan 13 operates, drawing airflow from the outside into the shield 12 and blowing it onto the processing area. The debris generated during cutting is blown to the other end and collected through the dust collection pipe 14. The exhaust fan 17 operates to create a negative pressure for extraction, which, together with the air intake fan 13, forms an air duct, causing the debris in the working area to move into the dust collection pipe 14. The debris is then collected by the dust collection box 16. In addition to providing working space for the cutter 4, the cutting opening 15 also provides space for debris to fall. The dust collection box 16 is located below the cutting opening 15. The system can directly collect the debris here. In actual operation, the working state of the exhaust fan 17 and the intake fan 13 can be adjusted so that the exhaust volume of the exhaust fan 17 is greater than the intake volume of the intake fan 13. This causes the gas at both ends of the shield 12 to flow into the shield 12, preventing the debris from spreading outward. When the pressure frame 9 moves, it will drive the sliding holes 30 at both ends to move. The sliding holes 30 will block the movable holes, preventing debris from flying out of the movable holes during cutting. In addition, the dust filter 18 will intercept the debris in the dust collection box 16, preventing the debris from flying out. After working for a period of time, the dust collection box 16 can be opened to clean the debris collected inside.
[0052] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
