Description

Technical Field

[0001] This utility model relates to the field of pencil manufacturing, specifically a deburring device for composite pencil manufacturing. Background Technology

[0002] Currently, pencils are mainly made of wood, which consumes a large amount of wood every year. This is inconsistent with the general trend of energy conservation and environmental protection, and has affected the development of the wooden pencil industry. Therefore, the pencil casings are now made of environmentally friendly and biodegradable plastic composite materials to replace traditional wooden pencils.

[0003] In the existing technology, in the production of composite pencils, the pencils are generally made in one piece. Since the pencils are relatively long, they need to be cut with a cutter to obtain the required length. During the production process, the outer surface of the pencil will have burrs, which usually need to be manually polished by hand with a grinding wheel. This operation is cumbersome. Based on this, this utility model proposes a deburring device for the production of composite pencils. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3 In this embodiment of the present invention, a deburring device for producing composite pencils includes a workbench 1, a conveying roller 2 for moving pencils is installed at the top of the workbench 1, a slitting seat 3 for cutting pencils is also installed at the top of the workbench 1, and a grinding mechanism 4 is set on the workbench 1; the grinding mechanism 4 includes a grinding unit and a transmission unit; the grinding unit is used to grind the outer surface of the pencil; the transmission unit is used to drive the pencil to rotate, thereby increasing the grinding area of ​​the pencil.

[0020] The grinding unit includes a base 401, a drive motor 402, and a grinding roller 403. The base 401 is fixed to the top of the workbench 1 and is used to support the pencil. The drive motor 402 is mounted on the top of the workbench 1 via a bracket and is located on one side of the pencil. The drive motor 402 is used to drive the grinding roller 403 to rotate. The grinding roller 403 is connected to the output end of the drive motor 402 via a rotating shaft and a coupling. The grinding roller 403 is used to grind the outer surface of the pencil.

[0021] The transmission unit includes a fixed rod 404, a transmission rod 405, a first gear 406, a second gear 407, and a transmission wheel 408. The fixed rod 404 is fixed to the outer wall of the shaft of the grinding roller 403 and is used to synchronously drive one end of the transmission rod 405 to rotate circumferentially. The transmission rod 405 is eccentrically rotatably connected to the outer wall of the fixed rod 404 and is used to synchronously drive the first gear 406 to rotate. The first gear 406 is rotatably mounted on the outer wall of the base 401 and is used to synchronously drive the second gear 407 to rotate. The second gear 407 is fixed to the outer wall of the transmission wheel 408 and is used to synchronously drive the transmission wheel 408 to rotate. The transmission wheel 408 is rotatably mounted on the outer wall of the base 401 and is used to provide power for the rotation of the pencil.

[0022] In this embodiment: by placing the pencil in the groove of the base 401 and passing it through the conveyor roller 2 and the slitting seat 3, the rotation of the conveyor roller 2 provides axial movement thrust to the pencil. The operation of the slitting seat 3 cuts the moved pencil. At the same time, the drive motor 402 also works synchronously, driving the grinding roller 403 to rotate clockwise. The rotating grinding roller 403 grinds the pencil on one side. Simultaneously, the fixing rod 404 at the end of the grinding roller 403 also rotates synchronously, and the rotating fixing rod 404 synchronously drives the outer wall to rotate eccentrically. When one end of the transmission rod 405 rotates circumferentially, the first gear 406, which is eccentrically connected to the other end of the transmission rod 405, will also rotate synchronously. The rotating first gear 406 provides a rotational thrust to the second gear 407, causing the second gear 407 to rotate counterclockwise. The counterclockwise rotating second gear 407 synchronously drives the transmission wheel 408 to rotate. The rotating transmission wheel 408 provides a rotational thrust to the pencil in contact with the outer wall, causing the pencil to rotate. This increases the contact area between the pencil and the grinding roller 403, polishing the burrs on the outer surface of the pencil and further improving work efficiency.

[0023] Please refer to this carefully. Figures 1-3 The two ends of the transmission rod 405 are eccentrically rotatably connected to the outer walls of the fixed rod 404 and the first gear 406, respectively. The two ends of the transmission rod 405 are equidistant from the axis of the fixed rod 404 and the first gear 406. The outer wall of the first gear 406 meshes with the outer wall of the second gear 407. The outer wall of the transmission wheel 408 is provided with a rubber pad to increase friction. The top of the base 401 is provided with a groove for the pencil to rotate. The outer wall of the grinding roller 403 is in contact with the outer wall of the fixed rod 404. One end of the drive motor 402 is electrically connected to an external power source through a wire.

[0024] In this embodiment: With this structure, when the grinding roller 403 rotates to grind the outer surface of the pencil, the transmission rod 405, the first gear 406, the second gear 407, and the transmission wheel 408 synchronously drive the pencil to rotate, and the direction of the pencil rotation is the same as the direction of the grinding roller 403 rotation, so that the outer surface of the pencil is better stressed and the grinding efficiency is increased.
