The driving roller and the driven roller are respectively connected with the two frames 201 in a rotating mode through bearings, the driving roller is driven by a first motor 203 through a leather belt, and the first motor 203 is connected with the bracket 1 through bolts. The upper roller way comprises an upper roller and an upper supporting rod 204, two ends of the upper roller are respectively connected with the upper supporting rod 204 in a rotating mode, and the upper supporting rod 204 is welded with the frame 201. The lower roller path comprises a lower roller 209 and a lower support rod 205, the lower roller 209 is provided with a central shaft 210, the roller can freely rotate around the central shaft 210, and two ends of the central shaft 210 are respectively connected with the lower support rod 205; the lower support rod 205 comprises a first sleeve 206 and a second sleeve 208, wherein a first end of the second sleeve 208 is sleeved in the first sleeve 206, a spring 207 is further arranged in the first sleeve 206, and the spring 207 is positioned between a top wall of the first sleeve 206 and the second sleeve 208; the second end of the second sleeve 208 is threadedly coupled to the central shaft 210, and the top of the first sleeve 206 is fixedly coupled to the connecting plate 211. The conveyor belt 202 places the spring 207 in compression. I.e., the lower support rod 205 is constructed like a spring damper. The first sleeve 206 is screwed or welded to the connection plate 211.

Below the conveyor belt 202 is a horizontal carrier plate 104, the width of the carrier plate 104 being the same as the width of the conveyor belt 202 and the length being smaller than the length of the conveyor belt 202. The right end of the bearing plate 104 is welded with the bracket 1, and the left end is welded with the connecting rod 103 welded at the bottom of the two frames 201. Two parallel conveying screws 7 are arranged on the left side of the bearing plate 4, the two conveying screws 7 are connected with a third motor 6 through a gear set 601, and the gear set 601 enables the two conveying screws to rotate in opposite directions. The first end of the conveying screw 7 is rotatably connected with the connecting rod 103, and the second end is rotatably connected with the bracket 1. The gear set 601 includes a driven gear 604 keyed to the second end of the conveyor screw 7, and a driving gear 603 installed between the two driven gears 604 and engaged with the driven gears, the driving gear 603 being engaged with a driving gear 602 on the third motor 6; the drive gear 602 is keyed to the output shaft of the third motor 6. The third motor 6 is screwed with the first bracket 101, and the first bracket 101 is welded with the bracket 1.

A sharpener 8 is provided at a position between the carrier plate 104 and the frame 201, the sharpener 8 being supported by the second bracket 102 and having a downward-inclined inclination angle a with the carrier plate 104. The sharpener 8 includes a drive motor and a grinding wheel. The grinding wheel is mounted on an output shaft of a driving motor, the driving motor is in bolted connection with the second support 102, and the second support is welded with the support 1. The sharpening machine is at least one. The sharpening machine may be disposed on the front side of the carrier plate 104 or on the back side of the carrier plate 104.

When in use, a pencil is put into the hopper 4, and then the pencil sharpening device is started. The material poking roller is driven by the second motor 1 to convey the pencils to the conveying screw rod 7 through the discharge port one by one in order, and the conveying screw rod 7 conveys the pencils to the direction of the bearing plate 4. Since the length of the carrier plate 4 is smaller than the length of the conveyor belt 202, the pencil first comes into contact with the conveyor belt 202. When the pencil reaches the bearing plate 4, the pencil rolls onto the bearing plate 4 under the driving of the conveying belt 202 and rolls forwards continuously, when the pencil passes through the sharpener 8, one end of the pencil is sharpened, and the sharpened pencil falls into the material receiving box 3 at the right end.

The lower support rod 205 is internally provided with a spring 207, so that the conveying belt 202 has larger extrusion force on the pencil, and the pencil cannot generate position deviation when the bearing plate 4 is damaged and transported and sharpened. When the conveying belt 202 is aged and loosened after being used for a long time, the lower supporting rod 205 can enable the conveying belt 202 to be in a tight state under the action of the spring 207, so that the conveying belt 202 can continuously and effectively generate enough extrusion force on the pencil, and the pencil sharpening device can work normally. Therefore, the belt does not need to be replaced or taken down for adjustment, and cost is saved.
