Description

Technical Field

[0001] This invention relates to the field of rock wool board production equipment technology, and in particular to a cutting device with adaptive function for rock wool board production. Background Technology

[0002] Rock wool board, as a high-quality thermal insulation material, is widely used in building exterior wall insulation, industrial plants, ship cabins and other fields due to its excellent fire resistance and sound insulation effect. In the production process of rock wool board, cutting is the key process that determines the dimensional accuracy and appearance quality of the finished product.

[0003] Currently, existing rock wool board cutting equipment typically uses a gantry-type cutting mechanism, which drives the cutting blade to rise and fall to achieve longitudinal cutting of the board. In actual production, due to the loose texture and fragile fiber structure of rock wool material itself, and the fact that the cutting blades of traditional cutting equipment are mostly rigidly pressed down and lack the function of pre-compression on the surface of the board, the board is prone to local warping or vibration under the impact force of the blade during cutting, resulting in uneven cuts. This leads to problems such as edge tearing, chipping, and splintering during cutting, which seriously affects product quality and subsequent installation and use. Summary of the Invention

[0004] In view of the technical problems mentioned in the background section, the present invention provides a cutting device with adaptive function for the production of rock wool boards.

[0005] The technical solution of the present invention is: a cutting device with adaptive function for rock wool board production, comprising a frame, multiple electric rollers rotatably connected inside the frame, a frame body fixedly installed on the upper part of the frame, and symmetrically distributed electric push rods installed on the lower side of the frame body. The telescopic ends of the symmetrically distributed electric push rods are jointly installed with a fixed shell. An electric rotating shaft is rotatably connected inside the fixed shell, and a fixed rod is fixedly installed inside the fixed shell. Two sliding plates are threadedly connected to the electric rotating shaft. The sliding plates are slidably connected to the fixed rod. A cutting blade is installed on the lower side of the sliding plate. Sliding rods are slidably connected to the opposing sides of the symmetrically distributed cutting blades. An extrusion plate is fixedly connected to the lower end of the sliding rod. A tension spring is connected between the sliding rod and the cutting blade.

[0006] Furthermore, the electric rotating shaft is a bidirectional lead screw with opposite thread directions at both ends, and the symmetrically distributed sliding plates are threadedly connected to both ends of the electric rotating shaft.

[0007] Furthermore, electric push rods are installed on both the left and right sides of the frame. An elastic telescopic rod is fixedly installed at the telescopic end of the electric push rod, and a connecting plate is fixedly connected to the telescopic end of the elastic telescopic rod.

[0008] Furthermore, the connecting plate is slidably connected to a sliding frame, and a second spring and a first spring are connected between adjacent ones. The elastic telescopic rod includes a fixed part and a telescopic part. A second spring is connected between the fixed part and the telescopic part. The fixed part is slidably connected to symmetrically distributed limiting plates. The limiting plates are used to limit adjacent telescopic parts. A third spring is connected between the limiting plate and the adjacent elastic telescopic rod. The sliding frame is fixedly connected to symmetrically distributed pressing members. The pressing members are pressed into the adjacent limiting plates.

[0009] Furthermore, the extrusion component is a wedge-shaped block, and the limiting plate is provided with an extrusion port that cooperates with the wedge-shaped block.

[0010] Furthermore, an electric push rod three is installed on the lower side of the frame, and a motor is fixedly installed on the telescopic end of the electric push rod three. A negative pressure adsorption plate is fixedly installed on the output shaft of the motor, and the negative pressure adsorption plate is used to adsorb rock wool board.

[0011] Furthermore, a distance sensor is installed at the top of the slide bar, which is used to detect the distance between it and the upper side of the adjacent cutting blade.

[0012] Furthermore, each of the symmetrically distributed sliding frames is equipped with a vacuum cleaner frame on its opposite side, a vacuum cleaner is mounted on the connecting plate, and a pipe connects the vacuum cleaner frame to the adjacent vacuum cleaner.

[0013] The beneficial effects are: the present invention connects the cutting blade and the extrusion plate in a floating manner through a sliding rod and a tension spring, thereby achieving adaptive pre-compression during the cutting process and suppressing tearing and edge chipping caused by the loose fiber structure of the rock wool board during cutting.

[0014] This invention uses an electric rotating shaft to drive two sliding plates and a cutting blade to move synchronously in opposite directions or in opposite directions, quickly adapting to the cutting needs of plates of different widths.

[0015] This invention achieves omnidirectional stable fixation of the sheet material during the cutting process through a lateral elastic positioning mechanism, avoiding edge and corner damage caused by rigid clamping, and providing stable lateral guidance for cutting long sheet materials.

[0016] This invention achieves intelligent monitoring and environmentally friendly dust removal during the cutting process by setting a distance sensor at the top of the slide bar and integrating a follow-up dust collection frame on the slide frame. This ensures that the cutting blade cuts into the board with the optimal pressure, guaranteeing a complete cut while avoiding crushing of the board or damage to the blade due to excessive pressure, thus realizing adaptive intelligent cutting.

Detailed Implementation

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0024] Example 1: A cutting device with adaptive function for rock wool board production. Please refer to [link / reference]. Figures 1 to 5 The cutting equipment includes a frame 1, which serves as the supporting foundation for the entire machine. Multiple electric rollers 2 are rotatably connected inside the frame 1 along the conveying direction to carry and convey rock wool boards. A frame body 3 is fixedly installed on the upper part of the frame 1. The frame body 3 is a portal structure that spans across the conveying path. Two symmetrically distributed electric push rods 4 are installed on the lower side inside the frame body 3. The telescopic ends of the two electric push rods 4 are connected to a fixed shell 5. The electric push rods 4 can drive the fixed shell 5 and its connecting parts to rise and fall as a whole to adapt to the cutting requirements of rock wool boards of different thicknesses.

[0025] Please see Figure 2 The fixed housing 5 has a parallel electric rotating shaft 6 and a fixed rod 7 inside. The electric rotating shaft 6 is a two-way lead screw with opposite threads at both ends. Two sliding plates 8 are threadedly connected to the electric rotating shaft 6. The sliding plates 8 slide with the fixed rod 7, so that when the electric rotating shaft 6 rotates, the two sliding plates 8 can move towards or away from each other under the guidance of the fixed rod 7, thereby adjusting the distance between them. A cutting blade 9 is installed on the lower side of each sliding plate 8 for longitudinal cutting of the rock wool board.

[0026] Please see Figure 2 To achieve adaptive clamping, each cutting blade 9 has a vertically arranged sliding rod 10 slidably connected to its opposite side (i.e., the side where the two cutting blades 9 are close to each other). The lower end of the sliding rod 10 is fixedly connected to a pressing plate 11, and the upper end of the sliding rod 10 passes through the cutting blade 9. A tension spring 12 is connected between the sliding rod 10 and the cutting blade 9. In its natural state, the tension spring 12 pulls the sliding rod 10 to make the pressing plate 11 reach the lower limit position. At this time, the bottom surface of the pressing plate 11 is flush with the blade of the cutting blade 9. When the cutting blade 9 descends and cuts into the rock wool board, the pressing plate 11 first contacts the surface of the board and is pushed upward. The tension spring 12 is stretched, thereby applying an elastic clamping force to the board on both sides of the cutting area to prevent the rock wool board from tearing or chipping due to uneven pressure during the cutting process.

[0027] Please see Figure 1 , Figure 3 and Figure 4 To achieve precise horizontal positioning and lateral support of the rock wool board, electric push rods 13 are symmetrically installed on the left and right sides of the frame 3. Each electric push rod 13 has an elastic telescopic rod 14 fixedly connected to its telescopic end. A connecting plate 15 is fixedly connected to the telescopic end of the elastic telescopic rod 14. A sliding frame 16 is slidably connected to the connecting plate 15, and a spring 17 is connected between the connecting plate 15 and the sliding frame 16, so that the sliding frame 16 has a certain elastic floating relative to the connecting plate 15.

[0028] Please see Figure 1 , Figure 3 and Figure 4 The elastic telescopic rod 14 includes a fixed part 18 and a telescopic part 19. The telescopic part 19 is slidably inserted into the fixed part 18, and a spring 23 is connected between the two to provide basic telescopic elasticity. Two symmetrically distributed limiting plates 20 are also slidably connected to the fixed part 18. A spring 21 is connected between the limiting plate 20 and the fixed part 18, so that the limiting plate 20 has a reset tendency. The limiting plate 20 is used to restrict the movement of the telescopic part 19 in the initial state (i.e., the locked state). Symmetrically distributed pressing members 22 are fixedly connected to the sliding frame 16. In this embodiment, the pressing member 22 is a wedge-shaped block. The limiting plate 20 is provided with a pressing port 24 that cooperates with the wedge-shaped block.

[0029] Please see Figure 5To further secure the rock wool board and prevent warping or displacement during cutting, an electric push rod 25 is installed on the lower side of the frame 1. The telescopic end of the electric push rod 25 is set upward and a motor 26 is fixedly installed thereon. A negative pressure adsorption plate 27 is fixedly installed on the output shaft of the motor 26. When the board is laterally positioned in the horizontal direction, the electric push rod 25 extends, causing the negative pressure adsorption plate 27 to contact the lower surface of the rock wool board. The board is firmly adsorbed by negative pressure. The motor 26 can drive the negative pressure adsorption plate 27 to rotate the board at a small angle according to the cutting angle required, ensuring that the cutting direction is consistent with the process requirements.

[0030] When rock wool boards need to be cut, the staff starts multiple electric rollers 2 to rotate, smoothly transporting the rock wool boards from the upstream conveyor line to the cutting station. When the boards are transported to the predetermined position (i.e. directly below the cutting blade 9), the electric rollers 2 stop rotating, and the boards are positioned to wait for cutting.

[0031] At the same time, the electric push rods 13 on both sides of the frame 3 extend simultaneously. During the extension process, the sliding frame 16 first contacts the side of the rock wool board and pushes the board to the center position. Then, the electric push rods 13 continue to extend, and the connecting plate 15 compresses the spring 17, so that the sliding frame 16 forms a flexible clamp on the side of the board. At the same time, the extrusion member 22 gradually inserts into the extrusion port 24 and uses the wedge-shaped inclined surface to push the two limiting plates 20 to move in opposite directions, overcoming the elastic force of the spring 21, thereby releasing the limiting plate 20 from limiting the telescopic part 19. At this time, the telescopic part 19 can freely extend and retract under the action of the spring 3 23, so that the sliding frame 16 can fit against the side of the rock wool board with a constant flexible force, providing stable lateral guidance for the cutting process and preventing the board from swaying during cutting. It is especially suitable for cutting long boards.

[0032] After the board is fixed horizontally, the bottom adsorption fixation begins. The electric push rod 25 on the lower side of the frame 1 is activated, pushing its telescopic end to extend upward. The motor 26 and negative pressure adsorption plate 27 installed on the telescopic end rise accordingly. After the negative pressure adsorption plate 27 contacts the lower surface of the rock wool board, the control system activates the negative pressure adsorption function to firmly adsorb and fix the board.

[0033] After positioning is completed, the cutting program is executed automatically. The electric push rod 4 on the upper side of the frame 3 is activated, pushing the fixed shell 5 downward. The cutting blade 9 installed on the lower side of the sliding plate 8 descends accordingly. During the descent of the cutting blade 9, the extrusion plate 11 first contacts the surface of the board. Since the extrusion plate 11 is floatingly connected to the cutting blade 9 through the slide rod 10 and the tension spring 12, after the extrusion plate 11 contacts the surface of the board, as the cutting blade 9 continues to descend, the extrusion plate 11 is pushed upward by the board. The slide rod 10 slides upward relative to the cutting blade 9, and the tension spring 12 is stretched, thereby applying an elastic clamping force to the board on both sides of the cutting area to prevent the rock wool board from tearing or chipping during the cutting process.

[0034] After the cutting blade 9 finishes cutting the board, the electric push rod 4 drives the entire cutting head to rise and reset. At the same time, the electric push rod 13 of the lateral positioning mechanism slightly retracts, releasing the pressure of the pressing part 22 on the limiting plate 20. The limiting plate 20 resets under the action of the spring 21 and relocks the telescopic part 19. The entire lateral mechanism automatically resets under the elastic force of the spring 17 and the spring 3 23 and disengages from the side of the board.

[0035] When different widths of boards need to be cut, the electric rotating shaft 6 (bidirectional lead screw) rotates automatically, driving the two sliding plates 8 to move towards or away from each other along the fixed rod 7, precisely adjusting the distance between the two cutting blades 9. In addition, the motor 26 can drive the negative pressure suction plate 27 to rotate the board at a small angle according to the required cutting angle, ensuring that the cutting direction is consistent with the board texture or process requirements.

[0036] Example 2: Based on Example 1, please refer to... Figure 2 To accurately sense the cutting depth, a distance sensor 28 is installed at the top of the slide bar 10. This sensor is used to detect the change in distance between itself and the upper side of the adjacent cutting blade 9 in real time. The amount of distance change reflects the compression of the extrusion plate 11, and thus indirectly reflects the flatness and actual thickness of the plate surface. Based on the feedback signal from the distance sensor 28, the control system dynamically adjusts the pressing speed and final position of the electric push rod 4 to achieve adaptive control of the cutting pressure.

[0037] Please see Figure 3 To reduce rock wool dust pollution during the cutting process, dust collection racks 29 are installed on the opposite sides of the two sliding racks 16. The openings of the dust collection racks 29 face the cutting area. A vacuum cleaner 30 is installed on the connecting plate 15. The dust collection racks 29 and the adjacent vacuum cleaners 30 are connected by pipes 31. During cutting, the vacuum cleaners 30 work continuously, and the dust generated is sucked up and collected in time through the dust collection racks 29. The dust collection racks 29 move with the sliding racks 16 and always remain in the position closest to the cutting point, so that the dust collection effect is optimal.

[0038] Throughout the cutting process, the vacuum cleaner 30 installed on the connecting plate 15 works continuously and is connected to the vacuum cleaner frame 29 on the sliding frame 16 through the pipe 31. The vacuum cleaner frame 29 is close to the cutting position and sucks in and collects the rock wool dust generated during cutting in a timely manner to prevent dust from spreading and polluting the environment. The vacuum cleaner frame 29 moves with the sliding frame 16 and always stays in the position closest to the cutting point to ensure the best dust suction effect.

[0039] Meanwhile, during the cutting process, the distance sensor 28 installed at the top of the slide bar 10 monitors the change in distance between the top of the slide bar 10 and the upper side of the adjacent cutting blade 9 in real time. This change in distance directly reflects the compression of the extrusion plate 11, and indirectly reflects the flatness and actual thickness of the plate surface. The control system receives the feedback signal from the distance sensor 28 and dynamically adjusts the downward pressing speed of the electric push rod 4 to ensure that the cutting blade 9 cuts into the plate with appropriate pressure, ensuring complete cutting while avoiding crushing of the plate or damage to the blade due to excessive pressure.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
