The bottom center of the pen placement tube 13 is connected to the top output end of the rotating motor 16. Several placement bins 14 are provided at the top of the pen placement tube 13. The cross-sectional shape of the placement bin 14 matches the cross-sectional shape of the pencil, so the pencil can be fixed for easy polishing. A grinder 11 is provided above the placement bin 14 at the top rear end of the pen placement tube 13. The grinder 11 is an existing mature technology, and its internal specific structure and working principle will not be described in detail here. A vertical plate 7 is provided at the top rear end of the recycling box 6, and a linear module 8 is provided in the vertical direction downward at the top center of the front side of the vertical plate 7. The surface of the linear module 8 is slidably connected to the module slider 9, and the module slider 9 is connected to the grinder 11 by a connecting rod 10.

[0025] It should be noted that the linear module 8 is an existing mature technology, and its internal specific structure and working principle will not be described in detail here.

[0026] Furthermore, ventilation holes are provided on the tops of both sides of the recycling drawer 4 .

[0028] It should be noted that the size of the air suction port 18 matches the size of several ventilation ports on the surface of the recovery drawer 4.

[0029] Specifically, when in use, the wind generated by the suction fan 18 will enter the recovery drawer 4 from the vent at the top side of the recovery drawer 4. At this time, dust will enter the interior of the recovery drawer 4 from the dust port and will be located in the vent of the recovery drawer 4. Therefore, the dust will be blocked by the dustproof net and collected in the recovery drawer 4.

[0030] Furthermore, a protective plate 5 is provided on the top of the recycling box 6 and on the outside of the pen placement tube 13. A notch 12 is provided vertically downward on the top back of the protective plate 5, and a connecting rod 10 is slidably connected to the notch 12.

[0034] Furthermore, an opening is provided on one side of the protective shell 1, and a sealing door is connected to the opening through a hinge. The other end of the sealing door is connected to the protective shell through a lock. When the pencils need to be placed in the placement bin 14, the sealing door needs to be opened. After all the pencils are placed, the sealing door needs to be closed.

[0035] Working principle: The utility model is a new type of pencil lead polishing equipment, which places the pencil end that needs to be polished upwards, and then places the pencil into one of the placement bins 14. After all the placement bins 14 are placed, the side sealing door is closed, and then the linear module 8 is started to move the module slider 9, thereby moving the polisher 11 to the top of the pencil, and the polisher 11 is started to polish the pencil lead and wooden pen holder at the top of the pencil to make it smooth, and the dust generated will be blocked by the protective plate 5, and a number of dust ports are opened at the top of the recycling box 6 and on the inner surface of the protective plate 5. After being blocked, the dust will enter the recycling drawer 4 from the dust port through the suction fan 17. During the whole process, the dust generated is located in a confined space and will not cause damage to the workers' bodies. The dust is recovered in the recycling drawer 4, which is convenient for the equipment to clean the dust generated.

[0036] After the pencil is polished, the linear module 8 is started again to move the polishing machine 11 upward, and then the rotary motor 16 is started. The rotation of the rotary motor 16 will rotate the pen placement barrel 13, as shown in FIG. Figure 2 As shown, all the placement bins 14 are located on a circumference of the pen placement barrel 13. When the pen placement barrel 13 rotates, the polished pencil will rotate away from the bottom of the polishing machine 11. After a new placement bin 14 is rotated to the bottom of the polishing machine 11, the above steps can be repeated to polish a new pencil.
