[0026] As an embodiment of the present application, the cutting guide mechanism 4 comprises a support guide plate 41, a guide square cylinder 42, a triangular distribution block 43, a sliding plate 44, a cutting knife 45, a connecting vertical plate 46 and a hydraulic cylinder 47; two support guide plates 41 are fixedly arranged below two symmetrical rollers of the rolling mechanism 3, and a guide square cylinder 42 is fixedly connected below the two support guide plates 41; a guide cavity 421 is formed in the guide square cylinder 42, and the upper end of the guide cavity 421 is below the symmetrical rollers; a triangular distribution block 43 is fixedly arranged in the lower end of the guide square cylinder 42; a discharge cavity 422 is formed between the two side slopes of the triangular distribution block 43 and the side wall of the guide cavity 421; a grain sorting mechanism 6 is arranged below the two symmetrical discharge cavities 422; at least two sliding grooves 423 are formed in the left side wall of the guide square cylinder 42 and communicate with the guide cavity 421; a sliding plate 44 is slidingly arranged in each sliding groove 423; a cutting knife 45 is arranged on the right end surface of each sliding plate 44; the left end surfaces of at least two sliding plates 44 are connected by a connecting vertical plate 46; and the hydraulic cylinders 47 are fixed on the left side wall of the machine body 1, and the piston rod end surfaces of the two hydraulic cylinders 47 are connected to the connecting vertical plate 46.

[0027] In the scheme designed in the application, when the rotating rollers in the rolling mechanism 3 roll the powder material into a sheet material, the sheet material will fall into the guide cavity 421 in the guide square cylinder 42. When the sheet material falls to the position above the triangular distribution block 43 in the guide cavity 421, the control box on the machine body 1 controls the extension of the piston rod of the at least two hydraulic cylinders 47, which drives the upper and lower sliding plates 44 to slide into the sliding groove 423 through the connecting vertical plate 46. The sliding sliding plate 44 drives the cutting knife 45 provided on the right end face to slide into the guide cavity 421, and the at least two cutting knives 45 cut the sheet material in the guide cavity 421 into small pieces. When the piston rod of the hydraulic cylinder 47 is retracted into the hydraulic cylinder 47, the connecting vertical plate 46 drives the cutting knife 45 to retract into the slot of the sliding groove 423 through the sliding plate 44.

When the sliding plate 44 drives the cutting knife 45 to slide into the sliding groove 423, the continuously rolled sheet material will continue to fall to the position above the triangular distribution block 43 in the guide cavity 421, and then the piston rod of the hydraulic cylinder 47 continues to extend to cut the sheet material into small pieces by the cutting knife 45. Thus, the probability of small particles or fine powder formed in the breaking and cracking stage of the rolled sheet material is reduced, the effect of the whole grain mechanism 6 on the rolling of the small pieces is improved, and the efficiency of the carbon nanotube in the dry granulation device is improved.

[0028] As an embodiment of the application, the top corner of the triangular distribution block 43 is arc-shaped, and the triangular distribution block 43 is provided with a vibrating cavity 431 inside, and the vibrating cavity 431 is provided with a vibrating assembly 5. The vibrating assembly 5 is used for vibrating the two side slopes and the arc top corner of the triangular distribution block 43.

[0029] In the scheme designed in the application, in order to avoid the blockage of the small pieces on the top end face of the triangular distribution block 43, which causes the small pieces to not slide into the two side discharge cavities 422, the top corner of the triangular distribution block 43 is designed as an arc shape, which facilitates the smooth sliding of the small pieces into the two side guide cavities 421. The vibrating assembly 5 is arranged in the vibrating cavity 431, which vibrates the two side inclined walls and the arc top corner of the vibrating cavity 431, thereby preventing the blockage of the small pieces in the discharge cavity 422, and affecting the effect of the whole grain mechanism 6 on the rolling of the small pieces.

[0031] In the design scheme of the present application, when the piston rod of the at least two hydraulic cylinders 47 pushes the connecting vertical plate 46 to move to the side wall of the material guiding square cylinder 42, the connecting vertical plate 46 will squeeze the strip-shaped air bag 51, at this time, the strip-shaped air bag 51 will be compressed, the gas in the strip-shaped air bag 51 will enter the support shaft pipe 53 in the rapping cavity 431 through the air outlet pipe 52 and the gas guide pipe 54, the gas in the support shaft pipe 53 will enter the fixed pipe 55 and push the sliding column 56 to extend out of the fixed pipe 55, and the plurality of sliding columns 56 that extend out will drive the plurality of rapping blocks 57 to contact the inclined surfaces and the circular arc top surface of the rapping cavity 431, when the connecting vertical plate 46 moves away from the side of the material guiding square cylinder 42, the compressed strip-shaped air bag 51 will return to its original state, and the gas in the support shaft pipe 53 will be sucked back through the gas guide pipe 54 and the air outlet pipe 52, so that the plurality of sliding columns 56 slide into the fixed pipe 55, and the plurality of rapping blocks 57 can be separated from the side wall of the rapping cavity 431. Therefore, as the connecting vertical plate 46 continuously reciprocates on the left side of the material guiding square cylinder 42, the strip-shaped air bag 51 will be continuously compressed and restored, and the plurality of groups of rapping blocks 57 will continuously rap the two side inclined surfaces and the circular arc top surface of the rapping cavity 431, so that the two side inclined surfaces and the circular arc top surface of the triangular material distributing block 43 made of elastic metal material can vibrate at the lower cavity opening of the material guiding cavity 421, thereby reducing the risk of blockage of the small section pieces in the discharging cavity 422 after being cut off, and improving the efficiency of the whole particle mechanism 6 in crushing the small section pieces into particles.
