A hydraulic cylinder 14 is provided at the bottom of the top plate 7. The end of the hydraulic cylinder 14 away from the top plate 7 is installed There is a cutting knife 15, and a guiding mechanism is arranged on the cutting knife 15. Two mutually symmetrical mounting plates 29 are fixedly installed above the cutting knife 15. Two mutually symmetrical rectangular tubes 19 are fixedly installed at the bottom of the two mounting plates 29. The two rectangular tubes 19 and the mounting plates 29 are in a tic-tac-toe shape. Plug-in plates 20 are plugged into the bottom of the two rectangular tubes 19. Rectangular slots 21 are opened at the bottom of the two plug-in plates 20. The inner cavities of the two rectangular slots 21 are provided with tensioning mechanisms. A protective shell 2 is arranged on the transmission mechanism. The protective shell 2 is installed on the baffle 1. Two mutually symmetrical sliding doors 3 are arranged on the front side of the protective shell 2. The protective net is placed on the conveyor belt 4. At this time, the transmission mechanism is driven to rotate by starting the motor 11, and the conveyor belt 4 is driven by the transmission mechanism to transport. When the conveyor belt 4 is transported to a certain position, the driving gear 10 and the half gear 9 in the transmission mechanism are in a non-engaged state; at this time, the placement personnel starts the hydraulic cylinder 14, and the hydraulic cylinder 14 will be able to push the cutting knife 15 to move horizontally downward with the assistance of the guide mechanism. When the cutting knife 15 moves downward, the mounting plate 29 installed above the cutting knife 15 will be able to drive the two rectangular cylinders 19 to move downward, because the inner cavities of the two rectangular cylinders 19 are connected with the plug through the second slide rail 28. The connecting plate 20 is closer to the conveyor belt 4 than the cutting knife 15, so the connecting plate 20 will be able to contact the conveyor belt 4 first, so the movable rod 22 in the tensioning mechanism can also contact the conveyor belt 4 at this time; when the hydraulic cylinder 14 continues to push, the connecting plate 20 moves upward until the limit block 27 passes through the rectangular groove 26 and contacts the extrusion block 30. At this time, the extrusion block 30 will be able to drive the connecting plate 23 to move downward with the assistance of the first slide rail 24. Therefore, the movable rod 22 in the tensioning mechanism can be opened by the downward extrusion force, and the protective net on the conveyor belt 4 is tightened, which is convenient for the cutting knife 15 to cut.

[0030] In a specific embodiment, the transmission mechanism includes a motor 11 and a rotating rod 12. The motor 11 is mounted on the side wall of the baffle 1. The output end of the motor 11 is connected to a driving gear 10. A half gear 9 is meshed and mounted on one side of the driving gear 10. The half gear 9 is fixedly mounted on one end close to the baffle 1 with a rotating rod 12. The rotating rod 12 is movable and penetrates the baffle 1. The end of the rotating rod 12 away from the half gear 9 is connected to the transmission wheel 13. In this configuration, the installation position and components of the transmission mechanism are determined.

[0031] Further, the guide mechanism includes two guide rods 8 and two guide rings 16, one end of the two guide rods 8 is respectively fixedly connected to the top of the two baffles 1, and the ends of the two guide rods 8 away from the baffles 1 are fixedly connected to the bottom of the top plate 7, the two guide rods 8 are symmetrical to each other, and the two guide rods 8 are sleeved with guide rings 16, the two guide rings 16 are symmetrical to each other, and connecting rods 17 are installed on the opposite side of the two guide rings 16, the two connecting rods 17 are symmetrical to each other, and the bottoms of the two connecting rods 17 are fixedly connected to the connecting rods 18, and the bottoms of the two connecting rods 18 are connected to the cutting knife 15. In this setting, the installation position and components of the guide mechanism are determined.

[0032] Furthermore, second slide rails 28 are arranged on opposite side walls of the inner cavity of the two rectangular cylinders 19, and each second slide rail 28 is symmetrical with each other. A plug-in board 20 is connected to one end of each second slide rail 28 opposite to each other. A rectangular groove 26 is provided on the top of the two plug-in boards 20, and the two rectangular grooves 26 penetrate and connect the rectangular notches 21. Limiting blocks 27 are installed on the top of the inner cavity of the two rectangular cylinders 19, and the two limiting blocks 27 are respectively fitted in the rectangular notches 21; the tensioning and relaxing mechanism includes two movable rods 22, and the two movable rods 22 are respectively arranged on the top of the two rectangular notches 21, and the two movable rods 22 are respectively arranged on the top of the two rectangular notches 21. A connecting plate 23 is movably mounted at one end of the movable rod 22, and first slide rails 24 are connected to both sides of the two connecting plates 23. Four first slide rails 24 are respectively arranged on the opposite side walls of the inner cavity of the two rectangular slots 21. Extrusion blocks 30 are installed above the two connecting plates 23. The two extrusion blocks 30 are symmetrical to each other and fit the two rectangular slots 21 respectively. Connecting blocks 31 are arranged on both sides of each movable rod 22, and each connecting block 31 is respectively fixedly connected to the connecting plate 23. A rotating shaft is arranged between each movable rod 22 and the connecting block 31, and a torsion spring is arranged on the rotating shaft. In this arrangement, it is ensured that when the hydraulic cylinder 14 continues to push, the plug-in plate 20 moves upward until the limit block 27 penetrates the rectangular slot 26 and contacts the extrusion block 30. At this time, the extrusion block 30 will be able to drive the connecting plate 23 to move downward with the assistance of the first slide rails 24. Therefore, the movable rod 22 in the tensioning mechanism can be opened by the downward extrusion force to tighten the protective net on the conveyor belt 4.

[0034] The implementation principle of the cutting device for producing a protective net in this embodiment is as follows: first, the protective net is placed on the conveyor belt 4, and the transmission mechanism is driven to rotate by starting the motor 11, and the conveyor belt 4 is driven by the transmission mechanism to transport. When the conveyor belt 4 is transported to a certain position, the driving gear 10 and the half gear 9 in the transmission mechanism are in a non-meshing state;

[0035] At this time, the placement personnel activates the hydraulic cylinder 14, and the hydraulic cylinder 14 will be able to push the cutting knife 15 to move horizontally downward with the assistance of the guide mechanism. When the cutting knife 15 moves downward, the mounting plate 29 installed above the cutting knife 15 will be able to drive the two rectangular cylinders 19 to move downward, because the inner cavities of the two rectangular cylinders 19 are connected to the plug-in board 20 through the second slide rail 28, and the plug-in board 20 is closer to the conveyor belt 4 than the cutting knife 15. Therefore, at this time, the plug-in board 20 will be able to contact the conveyor belt 4 first, so at this time, the movable rod 22 in the tensioning mechanism can also contact the conveyor belt 4;

[0036] When the hydraulic cylinder 14 continues to push, the plug-in plate 20 moves upward until the limit block 27 passes through the rectangular groove 26 and contacts the extrusion block 30. At this time, the extrusion block 30 will be able to drive the connecting plate 23 to move downward with the assistance of the first slide rail 24. Therefore, the movable rod 22 in the tensioning mechanism can be opened by the downward extrusion force, and the protective net on the conveyor belt 4 is tightened, which is convenient for the cutting knife 15 to cut.
