[0002] A pencil is a type of pen used for writing and sketching. It has a history of more than 400 years. Among them, pencils for sketching are divided into many types, which can be divided into three stages of development: graphite, wooden pen and capped pencil.
[0003] Pencil processing usually uses a sharpening and cutting machine with a single spiral cutter head. When sharpening, the spiral cutter head makes a circular motion at the front end of the pencil, cutting the pencil layer by layer to achieve the purpose of sharpening. Currently, some existing sharpening and cutting devices do not have a sawdust collection function, or use manual collection, which is inefficient. Excessive accumulation of sawdust will also affect the cutting efficiency, easily causing the cut lead to breakage, resulting in rework and wasting resources.

After the support frame 1 is placed in the designated position, the cut pencil is placed on the surface of the conveyor belt 3 and blocked by the limit plate 6. At the same time, when the conveyor belt 3 is moving, the pencil rubs against the limit plate 6 to complete the rotation of the pencil. Then the pencil enters the interior of the rectangular box 7 and rubs against the sand plate 9 to complete the sharpening of the pencil. After the pencil debris accumulates on the top of the fixed platform 8, it will automatically flow to the guide plate 10. Due to the inclined design of the guide plate 10, the debris finally falls to the surface of the platform 11.
[0027] Furthermore, in this embodiment, a collection trough 12 is provided inside the platform 11, and square frames 13 are fixedly connected to both ends of the platform 11. An extension block 14 is fixedly connected to the adjacent side of the square frame 13. Through grooves are provided inside and at the bottom of the extension block 14, through which debris is gathered and pushed into the collection trough 12, thereby completing the unified collection of the debris.
[0028] Furthermore, in this embodiment, the internal sliding connection of the through slot is connected to a limit rod 15, the bottom of the limit rod 15 is fixedly connected to a brush 16, the end of the limit rod 15 away from the through slot is fixedly connected to a rolling ball, the top of the rolling ball is provided with a receiving groove, and the internal accommodating groove is rotatably connected to a universal ball 17. By reciprocating the limit rod 15 inside the through slot, the limit rod 15 drives the brush 16 to move after the insertion and withdrawal motion, and the debris scattered on the surface of the platform 11 is gathered and pushed into the inside of the collection groove 12.
[0029] Furthermore, in this embodiment, the interior of the universal ball 17 is fixedly connected to a column 18, the top of the column 18 is rotatably connected to a linkage frame 19, the top of the linkage frame 19 is rotatably connected to an insertion shaft, the outer portion of the insertion shaft is rotatably connected to a rotating sleeve 20, the end of the rotating sleeve 20 away from the insertion shaft is fixedly connected to a connecting ear 21, the inner portion of the connecting ear 21 is rotatably connected to a screw rod 22, the outer portion of the screw rod 22 is threadedly connected to a threaded sleeve 23, the outer portion of the threaded sleeve 23 is rotatably connected to a connecting shaft, and by connecting one end of the connecting shaft to the output end of the motor The connection is made so that the connecting shaft drives the connecting ear 21 to rotate, and then the rotating sleeve 20 rotates synchronously, and the linkage frame 19 swings, and then the column 18 swings on the universal ball 17, and the ball moves back and forth, so that the limit rod 15 moves inside the through groove. By connecting the screw rod 22 to the motor and rotating it, the threaded sleeve 23 is changed to move to the eccentric position of the screw rod 22, so that the connecting shaft is located at the eccentric position of the rotating sleeve 20 and rotates, thereby increasing the sliding distance of the limit rod 15 and greatly improving the moving distance of the brush 16.
[0030] Furthermore, in this embodiment, the top end of the guide plate 5 is fixedly connected to a transverse plate 24, the transverse plate 24 extends to the outside of the guide plate 5, and the inner side wall of the guide plate 5 is fixedly connected to a mounting bracket 25. The mounting bracket 25 is rotatably connected to a disc inside, and the eccentric part of the disc is rotatably connected to a connecting plate 26. The bottom end of the connecting plate 26 is rotatably connected to a blade 27. By inserting a pencil into the interior of the transverse plate 24, the connecting plate 26 is driven to perform a circular motion by the rotation of the disc, so that the blade 27 completes the lifting motion, cuts the pencil, and facilitates the product. Finally, the pencil falls from the inside of the square groove to the inside of the blanking plate 4.
[0031] Furthermore, in this embodiment, a square groove is provided inside the transverse plate 24, and a sleeve 28 is rotatably connected to the bottom end of the guide plate 5.

When the arcuate groove 29 moves to the bottom, the orderly unloading of the pencils is completed, so that the cut pencils enter the top of the conveyor belt 3.
[0032] In this embodiment, the implementation scenario is specifically as follows: by inserting the pencil into the inside of the horizontal plate 24, the rotation of the disc drives the connecting plate 26 to perform a circular motion, so that the blade 27 completes the lifting motion, cuts the pencil, and is convenient for product delivery. Finally, the pencil falls from the inside of the square groove to the inside of the blanking plate 4, and by rotating the sleeve 28, a pencil will be stuck in the inside of the arc groove 29 at the same time. When the arc groove 29 moves to the bottom, the orderly discharge of the pencil is completed, so that the cut pencil enters the top of the conveyor belt 3 and is blocked by the limit plate 6. At the same time, when the conveyor belt 3 moves, the pencil rubs against the limit plate 6 to complete the rotation of the pencil. Then the pencil enters the inside of the rectangular box 7 and rubs against the sand plate 9 to complete the sharpening of the pencil. The pencil debris is fixed on the After accumulation on the top of the platform 8, it will automatically flow to the guide plate 10. Due to the inclined design of the guide plate 10, the debris will finally fall to the surface of the platform 11. By connecting one end of the connecting shaft to the output end of the motor, the connecting shaft drives the connecting ear 21 to rotate, and then the rotating sleeve 20 rotates synchronously, and the linkage frame 19 swings, and then the column 18 swings on the universal ball 17, and the rolling ball moves back and forth, so that the limit rod 15 moves inside the through groove. By connecting the screw rod 22 to the motor and rotating it, the threaded sleeve 23 is changed to move to the eccentric point of the screw rod 22, so that the connecting shaft is located at the eccentric point of the rotating sleeve 20 and rotates, increasing the sliding distance of the limit rod 15, and greatly increasing the moving distance of the brush 16, thereby gathering the debris scattered on the surface of the platform 11 and pushing it into the collection tank 12.
