[0032] A cutter 2, which is movably arranged on the frame 1, and the cutter 2 is used to cut the plate;

[0033] A guide device 3, wherein two guide devices 3 are movably arranged on both sides of the frame 1, and two ends of the tool 2 are connected to the two guide devices 3 respectively;

[0034] A lifting device 4 is disposed on the frame 1 , and is used to drive the guide device 3 to move up and down.

[0035] In this solution, the lifting device 4 is connected to the guide device 3, and both are arranged on the frame 1. There is a set of guide devices 3 on each side of the frame 1. The lifting device 4 can be one group or two groups. The tool holder of the tool 2 is installed on the two guide devices 3 on both sides of the frame 1 and can move up and down with the guide device 3. The lifting device 4 drives the tool 2 to move up and down through the guide device 3 during the lifting process, so that the plate conveyed to the cutting machine is cut.

[0036] An electric box is also provided on one side of the cutting machine, and a PLC integration (control module) is provided in the electric box, and the activity states of the lifting device 4, the guide device 3 and the tool 2 are controlled by the PLC integration.

[0037] Further, the guide device 3 includes a guide 31, an optical axis 32 and a mounting plate 33, wherein the optical axis 32 is vertically arranged on the side wall of the frame 1, the guide 31 is movably arranged on the optical axis 32, the mounting plate 33 is connected to the guide 31, and the output end of the lifting device 4 is connected to the mounting plate 33. The guide device 3 and the lifting device 4 are connected via the mounting plate 33, and the guide 31 can move up and down along the optical axis 32 under the drive of the lifting device 4 to drive the tool 2 to move up and down to complete the cutting of the plate, with a simple structure and high cutting efficiency for the plate.

[0038] Furthermore, it also includes a synchronization device 5 for keeping the movement trends of the two guide devices 3 synchronized, the synchronization device 5 is arranged on the frame 1, and the two ends of the synchronization device 5 are respectively connected to the guide devices 3 on both sides. The guide devices 3 on both sides of the frame 1 are connected through the synchronization device 5. When there is a height difference between the guide devices 3 on both sides, the positions of the guide devices 3 are automatically adjusted under the action of the lifting devices 4 on both sides until they are adjusted to the same height, thereby achieving synchronous lifting of the guide devices 3 on both sides.

[0039] Furthermore, the synchronization device 5 includes a synchronization shaft 51, a bearing 52, a bearing seat 53 and a synchronization swing rod 54. The synchronization shaft 51 is arranged on the frame 1. Two bearing seats 53 are respectively arranged on both sides of the frame 1. Both ends of the synchronization shaft 51 are respectively rotatably arranged on the two bearing seats 53, and both ends extend to the outside of the bearing seats 53. Both ends of the synchronization shaft 51 are respectively connected to two synchronization swing rods 54. A guide groove 541 is provided on the synchronization swing rod 54. The mounting plate 33 is provided with the bearing 52, and the bearing 52 is movably arranged in the guide groove 541.

[0040] The synchronization device 5 is composed of a synchronization swing rod 54, a bearing 52, a bearing seat 53, and a synchronization shaft 51. The synchronization swing rod 54 is fixedly connected to the synchronization shaft 51, and the synchronization swing rod 54 and the synchronization shaft 51 can rotate in the bearing seat 53. The guide device 3 is movably connected to the synchronization device 5 through the bearing 52, and the bearing 52 can slide in the guide groove 541 of the synchronization swing rod 54. When the lifting devices 4 on both sides are not synchronized, the guide devices 3 on both sides will produce a height difference. At this time, the guide devices 3 on both sides will generate vertical and opposite forces on the synchronization swing rod 54 through the bearing 52. Since the bearing 52 can slide in the guide groove 541 of the synchronization swing rod 54, the bearing 52 is automatically adjusted in the guide groove 541 of the synchronization swing rod 54 under the action of two opposite forces, until the two opposite forces offset each other to achieve balance, so that the guide devices 3 on both sides are lifted to the same height, ensuring the lifting synchronization of both sides.

[0041] Furthermore, the lifting devices 4 are provided on both sides of the frame 1, and the output ends of the two lifting devices 4 are respectively connected to the mounting plate 33. The guide devices 3 on both sides of the frame 1 are respectively driven by the corresponding lifting devices 4, and the movement trends of the two lifting devices 4 are the same, so that the tool 2 can better cut the plate.

[0042] Furthermore, the frame 1 includes two vertically arranged side panels 12, and a working space 121 is provided between the two side panels 12. The tool 2 and the workbench 11 are both arranged in the working space 121, the tool 2 is arranged above the workbench 11, the front side of the workbench 11 is a feeding end 13, and the rear side of the workbench 11 is a discharging end 14; at the discharging end 14, a sensor 6 for sensing the plate is provided on at least one of the side panels 12.

[0043] In the working space 121 , the cutter 2 moves up and down to cut the plate on the working table 11 , and the sensor 6 is mainly used to sense whether a plate is transported into the working space 121 to drive the lifting device 4 to start operating.

[0044] Furthermore, the discharge end 14 is further provided with a guide plate 15, which is connected to the workbench 11 and is tilted downward from one end close to the workbench 11 to one end away from the workbench 11. The tilted guide plate 15 facilitates the unloading of the cut sheet.

[0045] Working principle of the cutting machine: 1. The discharge end 14 of the cutting machine is connected to the external waste collection device, and the feed end 13 is connected to the residual material conveying mechanism; 2. When the panel saw cuts the board, the residual material generated is transported to the cutting machine through the conveying mechanism; 3. When the residual material is transported from the feed end 13 of the cutting machine to the discharge end 14, the sensor 6 senses the board, and the PLC (control module) inside the cutting machine transmits a signal to stop the conveying mechanism, and at the same time drives the lifting mechanism to descend, so that the cutting knife moves downward to cut the residual material on the workbench 11; 4. The cut waste slides to the waste collection device at the discharge end 14 of the cutting machine through the guide plate 15; 5. After the residual material is cut, the board sensing device does not sense the board, and the PLC inside the cutting machine transmits a signal to start the conveying mechanism, continue to convey the residual material to the cutting machine, and repeat the above steps.

[0046] Of course, in other embodiments, the cutting machine of this solution may not be used to cut residual materials, but may be used to cut conventional plates.

[0047] Furthermore, the frame 1 is also provided with a cover plate 16, and the cover plate 16 covers the tool 2, the guide device 3, the lifting device 4 and the synchronization device 5. The cover plate 16 mainly plays a protective role. The cover plate 16 of this scheme includes a rear cover plate 16, a front cover plate 16, a top cover, a left cover, a right cover and a front cover, wherein the top cover, the left cover and the right cover are arranged on the outside of the frame 1, and the inner shell of the top cover is provided with the manual control and hydraulic component integration of the cutting machine, and the left cover and the right cover cover the lifting device 4, the synchronization device 5 and the guide device 3 inside, which are isolated from the external space, and play a better protective role. The rear cover plate 16 and the front cover plate 16 are respectively located at the feed end 13 and the discharge end 14. The rear cover plate 16 can prevent the residual material from tilting to the other side due to the force on one side when the plate is cut; the front cover plate 16 can prevent the waste material after cutting from splashing, and a front cover is also provided on the outside of the front cover plate 16 to play a further protective role.

[0048] Furthermore, the lifting device 4 is a hydraulic cylinder or a pneumatic cylinder. The power source of the cutting machine can be a hydraulic cylinder, which has the characteristics of large output force, stable performance and convenient maintenance, and can effectively drive the guide device 3 to move up and down for a long time. Of course, in other embodiments, the lifting device 4 can also be a pneumatic cylinder, or a motor and other structures can be used to form the lifting device 4.

[0049] Furthermore, a plurality of spaced support portions 17 are provided on the outer side of the bottom of the side panel 12. The support portions 17 on the side panel 12 of the frame 1 support both sides of the frame 1 to ensure the stability of the frame 1 during the cutting process. The support portion 17 can be set to an approximate triangular shape, with both sides respectively against the side panel 12 and the base of the frame 1, which has better stability. Screw holes can be opened on the base of the frame 1, and the base can be firmly fixed to the ground by bolts.
