Description

Technical Field

[0001] The utility model relates to the technical field of building board production, in particular to a double-knife tracking cutting device. Background Art

[0002] In order to make the gypsum board more beautiful, the usual method is to paste the composite film on the decorative surface of the gypsum board. The laminated gypsum board uses a special high-strength paper-faced gypsum board as the substrate, adopts a special process, and presses a high-quality film on the surface, so that the surface of the laminated gypsum board has a variety of textures and a unique visual effect, which can fully meet the needs of personalized decoration. The laminated gypsum board has the characteristics of health and environmental protection, durability, no dust, moisture-proof, mildew-proof, anti-sag, easy to clean and easy to maintain.

[0003] When laminating the gypsum board, multiple gypsum boards are conveyed by the conveyor roller and passed through the laminating device in sequence at intervals. After laminating, the two adjacent gypsum boards are still connected together under the action of the composite film. It is necessary to use a cutting device to cut the composite film at the gap between the multiple gypsum boards connected by the composite film, so as to form multiple independent laminated gypsum boards. The connected composite films can be cut off before entering the subsequent processing steps.

[0004] At present, when the cutting equipment cuts the composite mold at the connection of the gypsum board, since the board is transported on the conveyor line, the roller vibration and the relative displacement between the board and the roller will cause the board transportation to be unstable, which will lead to deviation in the cutting position, resulting in low cutting accuracy and accidental damage to the gypsum board. Moreover, after the cutting equipment completes the single-knife cutting, film material will always remain at the tail and head of the gypsum board, affecting the next process. Utility Model Content

[0005] In order to solve the problem of cutting effect of gypsum board after lamination, the utility model provides a double-knife tracking cutting device.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is: a double-knife tracking and cutting device, including a support frame, a plurality of conveying rollers are arranged on the support frame, and a first movable component that can move forward and backward along the conveying direction of the conveying roller is arranged on the left and right sides of the support frame, a second movable component is arranged on the first movable component, and a connecting bridge is arranged on the top of the second movable component, and the connecting bridge connects the left and right second movable components, and a fixed knife cutting component and a movable knife cutting component that can move left and right along the connecting bridge are respectively arranged on the front and rear sides of the connecting bridge, and the fixed knife cutting component and the movable knife cutting component can both move up and down.

Guide blocks matching the guide rails of the connecting bridge 9 are arranged on both sides of the connecting frame 504. Synchronous pulleys are arranged on the left and right ends of the connecting bridge 9. Synchronous belts are arranged on the outer sides of the left and right synchronous pulleys. The connecting frame 504 is connected to the top of the upper synchronous belt. When the synchronous pulley rotates, the synchronous belt is driven to rotate, thereby driving the connecting frame 504 to move left and right along the guide rails on the connecting bridge 9. A movable knife cutting assembly 7 is arranged in front of the connecting frame 504, and a fixed knife cutting assembly 5 is arranged at the rear of the connecting frame 504.

[0030] The fixed knife cutting assembly 5 includes a fixed knife lifting cylinder 501 arranged behind a connecting frame 504, a fixed knife motor 502 is arranged at the telescopic end of the fixed knife lifting cylinder 501, a fixed knife 503 is arranged on the output shaft of the fixed knife motor 502, and the rotating cutting direction of the fixed knife 503 is perpendicular to the horizontal plane. Among them, the fixed knife lifting cylinder 501 controls the fixed knife 503 to move up and down, the connecting frame 504 controls the fixed knife 503 to move left and right with the movement of the synchronous belt, and the fixed knife motor 502 provides power for the fixed knife 503.

[0031] The moving knife cutting assembly 7 includes a moving knife lifting cylinder 701 arranged in front of the connecting frame 504, an adjusting module 702 is arranged at the telescopic end of the moving knife lifting cylinder 701, a moving knife motor 703 is arranged below the adjusting module 702, a moving knife 704 is arranged on the output shaft of the moving knife motor 703, and the rotating cutting direction of the moving knife 704 is perpendicular to the horizontal plane, wherein the adjusting module 702 is an existing device, and the adjusting module 702 is specifically a standard part of a motor drive and a screw rod linear guide rail, and the adjusting module 702 can automatically adjust the horizontal distance between the moving knife 704 and the fixed knife 503 according to the data fed back by the system, so that the distance between the moving knife 704 and the fixed knife 503 is equal to the distance between the plate.

[0032] The fixed knife cutting assembly 5 and the movable knife cutting assembly 7 cooperate with each other to adjust the horizontal spacing between the fixed knife 503 and the movable knife 704 to match the spacing between the plates, ensuring that the fixed knife 503 and the movable knife 704 can directly cut the film material in the middle of the plate, thereby improving the cutting quality and not affecting the next process.

[0033] A pressure plate assembly 4 is provided on the opposite side of the left and right first movable assemblies 2. The pressure plate assembly 4 is arranged as a whole behind the fixed knife cutting assembly 5. The pressure plate assembly 4 includes a pressure plate cylinder 401 arranged on the first movable assembly 2. The telescopic ends of the left and right pressure plate cylinders 401 are connected with a pressure plate 402. The pressure plate 402 can press the front end of the plate to improve the stability of the cutting of the coated plate.

[0034] A pressing assembly 6 is provided at the rear feed of the support frame 1. The pressing assembly 6 includes a gantry 601 provided at the rear end of the support frame 1. A pressing roller 602 with adjustable height is provided in the gantry 601. The gantry 601 is provided with height-adjusting tracks at both ends of the pressing roller 602 and at the connection between the gantry 601 and the gantry 601. The pressing roller 602 can be fixed at any height of the height-adjusting track so that the pressing roller 602 can press gypsum boards of different thicknesses. A state detection sensor is provided in the front middle of the top of the gantry 601. The state detection sensor includes a photoelectric sensor, an infrared sensor, and a corresponding optical fiber 603, etc. Here, the radiating optical fiber 603 is taken as an example. The radiating optical fiber 603 can automatically detect the distance between the front and rear plates. The moving knife cutting assembly 7 automatically adjusts the moving knife 704 and the fixed knife 503 to a suitable distance according to the distance detected by the radiating optical fiber 603. At the same time, the radiating optical fiber 603 can also detect and calculate the conveying position of the plate head in the conveying. When the plate head reaches the bottom of the pressing plate assembly 4, the pressing plate cylinder 401 in the pressing plate assembly 4 moves down to control the pressing plate 402 to press the plate, so as to prevent the plate from moving forward and backward when the composite film of the plate is cut, thereby improving the stability and quality of the film-coated plate cutting. A speed detector, a speed detector meter 604, etc. are also arranged in front of the radiating optical fiber 603. Here, the meter 604 is taken as an example. The meter 604 can feedback the moving speed of the plate on the conveying roller 3 in real time. The first moving assembly 2 matches the speed feedback by the meter 604 to ensure that the first moving assembly 2 moves at the same speed as the plate.

[0035] A collecting box 10 is provided at the bottom of the support frame 1. The collecting box 10 can collect the composite film cut by the fixed knife cutting assembly 5 and the movable knife cutting assembly 7, so as to facilitate the collection of waste materials and can be cleaned and maintained regularly.

[0036] The double-blade tracking and cutting device also includes an electrical control system, which can control the various components in the double-blade tracking and cutting device to cooperate with each other to complete the cutting work of the laminated gypsum board.

[0037] When the utility model is used, the coated gypsum board enters the conveying roller 3 through the pressing roller 602. In the process of conveying the board by the conveying roller 3, the board passes through the corresponding optical fiber 603 and the meter 604 in sequence. When the corresponding optical fiber 603 detects the board head and calculates that the board head reaches the bottom of the pressing plate assembly 4, the pressing plate cylinder 401 in the pressing plate assembly 4 controls the pressing plate 402 to move downward to press the board. At the same time, the first conveying assembly obtains the signal of the board movement speed fed back by the meter 604, and moves forward at the same speed as the board. The fixed knife 503 in the fixed knife cutting assembly 5 moves downward under the control of the fixed knife 503 cylinder, and the fixed knife 503 cuts the composite film at the board head from right to left under the drive of the connecting frame 504.

[0038] When cutting the first sheet, since there is no other sheet in front of the sheet, it is only necessary to cut off the composite film at the head of the first sheet. During cutting, only the fixed knife cutting assembly 5 is required to work, and the moving knife cutting assembly 7 does not perform any action. After the cutting of the head of the first sheet is completed, the fixed knife 503 cylinder in the fixed knife cutting assembly 5 controls the fixed knife 503 to rise and retract and move to the initial position along the track of the connecting bridge 9, and the pressing plate 402 in the pressing plate assembly 4 also rises and retracts to the initial position under the control of the pressing plate cylinder 401. At the same time, the first moving assembly 2 returns to the initial position.

[0039] When the second sheet of plate enters the conveying roller 3, the reflecting optical fiber 603 automatically detects the distance between the front and rear sheets of plate, and feeds back the distance information to the adjusting module 702 in the movable knife cutting assembly 7. The adjusting module 702 automatically adjusts the distance between the movable knife 704 and the fixed knife 503 according to the distance between the sheets of plate, so that the distance between the movable knife 704 and the fixed knife 503 is equal to the distance between the two sheets of plate. When the optical fiber 603 detects and calculates that the head of the second sheet reaches the bottom of the pressing plate assembly 4, the pressing plate cylinder 401 in the pressing plate assembly 4 controls the pressing plate 402 to move downward to press the sheet. At this time, the fixed knife 503 in the fixed knife cutting assembly 5 and the moving knife 704 of the moving knife cutting assembly 7 move downward at the same time under the control of the fixed knife 503 cylinder and the moving knife 704 cylinder respectively. Driven by the connecting frame 504, the excess composite film between the sheets is cut synchronously from right to left. While the fixed knife cutting assembly 5 and the moving knife cutting assembly 7 are cutting the composite film, the meter 604 feeds back the moving speed of the sheet in real time, and the first moving assembly 2 moves forward at the same moving speed as the sheet. After the cutting is completed, the fixed knife 503 and the moving knife 704 rise and retract to the initial position under the control of the fixed knife 503 cylinder and the moving knife 704 cylinder respectively, and the first moving assembly 2 also returns to the initial position. The subsequent film-coated sheet cutting repeats the above process.

[0040] After the cutting is completed, the excess composite film in the middle can automatically fall into the collection box 10 at the bottom of the support frame 1, and the staff can regularly clean and maintain it.

[0041] When the thickness of the conveyed plate changes, the staff can input the parameters of the plate thickness into the system, and the second moving component 8 and the pressing roller 602 will automatically adjust to the appropriate height according to the specific parameters of the plate to facilitate cutting.

[0042] When the length of the delivered plate changes, the staff can input parameters of different lengths, and the fixed knife cutting assembly 5 and the movable knife cutting assembly 7 automatically adjust the cutting position.

[0043] The "front" and "rear" mentioned above are defined according to the conveying direction of the coated gypsum board. The conveying direction of the coated gypsum board is defined as "front", which is only for the convenience of describing the embodiments of the present invention and does not impose any restrictions on the substantive content of the embodiments.
