[0027] The top of each moving block 4 is fixedly connected to a connecting plate 5. Each connecting plate 5 is fixedly connected to a clamping plate 8 via a plurality of springs 6. Each connecting plate 5 is slidably mounted with a limit rod 7. The opposite ends of each limit rod 7 are fixedly connected to the corresponding clamping plate 8.

[0028] A fixing frame 16 is fixedly mounted on the upper end surface of the machine platform 1 , and guide rods 21 are slidably mounted on both sides of the fixing frame 16 , and a cutter 20 is fixedly mounted on the bottom end of the guide rods 21 .

[0029] A threaded rod 17 is rotatably mounted on the fixing frame 16. A sleeve 18 is threadedly connected to the outer side of the bottom end of the threaded rod 17. The bottom end of the sleeve 18 is fixedly connected to the cutter 20. A linkage assembly is provided between the threaded rod 17 and the screw rod 3.

[0030] The linkage assembly includes a first pulley 11, a belt 12, a second pulley 13, a connecting rod 14, a first bevel gear 15, and a second bevel gear 22. The first pulley 11 is fixedly mounted on the side of the screw 3 facing away from the motor 2. A fixing plate 19 is fixedly mounted on the upper end surface of the fixing frame 16 at a position corresponding to the threaded rod 17. The connecting rod 14 is rotatably mounted on the fixing plate 19. A support plate is fixedly mounted on the upper end surface of the machine 1, and one end of the connecting rod 14 is rotatably connected to the support plate. The second pulley 13 is fixedly mounted on the side of the connecting rod 14 near the support plate.

[0031] A through hole is formed on the machine 1. The first pulley 11 and the second pulley 13 are connected via a belt 12, which is arranged inside the through hole.

[0032] The other end of the connecting rod 14 is fixedly mounted with a first bevel gear 15, and the top end of the threaded rod 17 is fixedly mounted with a second bevel gear 22. The first bevel gear 15 is meshedly connected with the second bevel gear 22.

[0033] Furthermore, a collecting box 23 is slidably mounted on the bottom of the machine 1 , and a through slot 10 is provided on the bottom surface of the placement slot 9 corresponding to the middle position of the two clamping plates 8 . The through slot 10 is communicated with the interior of the collecting box 23 .

[0034] Working principle:

[0035] During use, the gypsum board to be cut is placed in the placement slot 9 of the machine table 1. The motor 2 is activated to rotate the screw 3, which in turn drives the two moving blocks 4 toward each other. The movement of the moving blocks 4 drives the corresponding connecting plates 5, which in turn drives the two clamping plates 8 toward each other. The two clamping plates 8 are close together and clamp the gypsum board. Soft pads are fixed on the opposing surfaces of the two clamping plates 8. The soft pads effectively prevent the gypsum board from being scratched or damaged due to excessive pressure.

[0036] In the process of the two splints 8 approaching each other, the screw rod 3 rotates and drives the first pulley 11 to rotate at the same time, and then drives the second pulley 13 to rotate through the belt 12. The rotation of the second pulley 13 drives the first bevel gear 15 to rotate through the connecting rod 14, and then drives the second bevel gear 22 to rotate, and then drives the threaded rod 17 to rotate. The rotation of the threaded rod 17 drives the sleeve 18 to move downward, and then drives the cutter 20 to move downward.

[0037] It should be noted that when the cutter 20 moves downward, the clamping plate 8 first contacts the gypsum board to clamp and limit the gypsum board. At this time, the two connecting plates 5 continue to approach each other, causing the spring 6 to compress. When the spring 6 contracts, the cutter 20 cuts the gypsum board.

[0038] After the cutting is completed, the gypsum board is taken out and the two plywoods 8 can be moved closer to each other to clean the gypsum board waste on the surface of the placement groove 9, and the waste is pushed from the through groove 10 into the collection box 23. There is no need for manual cleaning by the staff, which ensures the safety of the staff.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
