Description

TECHNICAL FIELD

[0001] The utility model relates to pencil sharpener technical field more specifically, relate to a pencil sharpener's waste chip compression mechanism and pencil sharpener. BACKGROUND

[0002] In the existing horizontal pencil sharpener design, the waste chip produced in the pencil sharpening process usually falls directly below the cutting position, forming a concentrated accumulation. This waste chip accumulation method is easy to cause the space utilization of the waste chip box to be insufficient, especially in the area far away from the cutting position, the accumulation of waste chips is less, causing the waste of space. At the same time, the waste chip is concentrated and accumulated below the cutting position, which also increases the difficulty of waste chip cleaning, which may cause the waste chip box to overflow or affect the normal operation of the pencil sharpener. SUMMARY

[0003] The utility model aims at solving one of the technical problems in the related art to some extent. Therefore, the utility model embodiment provides a waste chip compression mechanism of pencil sharpener, which is effectively transmitted to the far end of the waste chip box by the self-rotation of the conveying part, optimizes the space utilization of the waste chip box, reduces the accumulation of waste chips, reduces the cleaning difficulty, and improves the cleanliness and stability of the pencil sharpener.

[0004] The utility model embodiment further provides a pencil sharpener with the waste chip compression mechanism of the pencil sharpener.

[0005] The technical scheme adopted by the utility model is as follows: a waste chip compression mechanism of pencil sharpener is provided, which comprises:

[0006] The conveying part is arranged in the waste chip box, and the conveying part is located below the cutting position;

[0007] The power source is connected with the conveying part and drives the self-rotation of the conveying part;

[0008] The conveying part transmits the waste chip falling thereon to the far end in the waste chip box through self-rotation.

[0009] After the above structure is adopted, the waste chip is no longer concentrated and accumulated below the cutting position, but is effectively transmitted to the far end area of the waste chip box far away from the cutting position through the self-rotation of the conveying part. In this way, the space in the waste chip box is more uniformly and fully utilized, and the waste chip is prevented from being concentrated and accumulated in the area close to the cutting position, so that the volume utilization rate of the waste chip box is improved. At the same time, the conveying part can also compact the waste chip, reduce the risk of waste chip overflow or excessive accumulation, improve the waste chip storage capacity of the waste chip box, and help to maintain the cleanliness and stable operation of the pencil sharpener.

[0010] According to one embodiment of the utility model, the conveying part is directly connected with the power source, that is, the power source directly drives the synchronous rotation of the conveying part; or

[0011] The conveying member is connected with the power source through a transmission structure, i.e., the power source drives the conveying member to rotate asynchronously or at different speeds.

[0012] According to an embodiment of the present application, the transmission structure comprises a gear set or a coil spring, for providing transmission power; when the power source is connected with the conveying member through the gear set, the gear set can change the transmission ratio to transmit the rotating force generated by the power source to the conveying member, so that the conveying member rotates at different speeds, thereby driving the shavings to be transported along the surface of the conveying member to the far end of the shavings box. When the power source is connected with the conveying member through the coil spring, the power source provides additional driving force to store energy in the coil spring, and the coil spring drives the conveying member to rotate asynchronously in the case of power source stoppage or abnormality.

[0013] According to an embodiment of the present application, the power source comprises a hand wheel and a motor; when the power source is the hand wheel, i.e., the pencil sharpener is a manual pencil sharpener, the user rotates the hand wheel to drive the conveying member to rotate, so that the user does not need to rely on external power supply, and the pencil sharpener is suitable for scenarios requiring portability or use in an environment without electricity.

[0014] On the other hand, when the power source is the motor, the pencil sharpener can automatically operate through the motor driving the gear set, thereby reducing the labor intensity of manual operation and improving the convenience and efficiency of use.

[0015] According to an embodiment of the present application, the power source drives the tool holder at the cutting position to rotate; i.e., the power source can be regarded as driving the conveying member alone, or as driving the conveying member and the tool holder simultaneously. In the case of driving the conveying member alone, the power source drives the conveying member to rotate, thereby transporting the shavings from the cutting position to the far end of the shavings box; while the rotation of the tool holder is provided by other independent driving systems, to ensure the normal operation of the pencil sharpening process. In the case of driving the conveying member and the tool holder simultaneously, the power source drives the tool holder to rotate through the transmission system to perform the pencil sharpening operation, and drives the conveying member to rotate to transport the shavings, thereby realizing the cooperative work of pencil sharpening and shavings transportation.

[0016] According to an embodiment of the present application, the box body of the shavings box is detachably connected with the pencil sharpener body; and / or

[0017] The box body of the shavings box is fixed on the pencil sharpener body, and the box body has a cover which can be opened and closed; in the design of detachable connection, the shavings box can be easily removed from the pencil sharpener body, facilitating the cleaning of the shavings and the replacement or cleaning of the shavings box. The user can easily remove the shavings box, to ensure regular cleaning and avoid excessive accumulation of shavings, which affects the normal operation of the pencil sharpener. In the design of fixed connection and having a cover which can be opened and closed, the shavings box is always fixed on the pencil sharpener body during use, thereby increasing the stability and convenience of use, and the design of the cover which can be opened and closed facilitates the pouring of the shavings and the cleaning of the box body, while avoiding the leakage of the shavings and keeping the working environment clean.

[0018] According to one embodiment of the utility model, the conveying piece has spiral blade; spiral blade design can effectively guide and transmit the scrap from the cutting position to the distal end of scrap box. When the power source drives the conveying piece to rotate, the spiral blade generates forward propulsion force by rotation, gradually pushes and conveys the scrap falling on it to the distal end area of scrap box. This spiral transmission structure not only can improve the conveying efficiency of scrap, but also can effectively prevent the scrap from being blocked or detained in the conveying process.

[0019] According to one embodiment of the utility model, the conveying piece is rotatably connected with the box body of scrap box through the connecting piece, and the connecting piece can drive the conveying piece to rotate relative to the box body in the box body. The setting of the connecting piece facilitates the assembly of the conveying piece.

[0020] According to one embodiment of the utility model, the connecting piece has a connecting part for connecting the power source; and / or

[0021] The connecting piece has a limiting part for limiting the axial position of the connecting piece; and / or

[0022] The connecting piece has a buckle part, and the buckle part passes through the connecting column on the box body and is buckled with the conveying piece.

In other embodiments, the scrap box 20 is fixedly installed on the pencil sharpener main body 10 and has a side opening cover (not shown in the figure). After the cover is opened, the scrap in the scrap box 20 can be poured out, facilitating cleaning and maintenance.

[0052] In combination Figure 3 As shown, in this embodiment, the power source 12 is a motor. The gear on the output shaft of the motor is engaged with the gear set 13. The gear set 13 is installed on the support frame 14 and connected with one end of the tool holder 15 through spline, so as to drive the tool holder 15 to rotate. The rotation of the tool holder 15 drives the pencil feeding assembly 16 to perform pencil feeding action. One gear in the gear set 13 is connected with the connecting gear 17. The connecting gear 17 is connected with the conveying member 22 through spline, further driving the conveying member 22 to rotate, and then transporting the scrap to the distal end area of the scrap box 20. This transmission structure enables the power source 12 to drive the tool holder 15 and the conveying member 22 at the same time, optimizing the cooperation between the pencil sharpening and scrap transportation.

[0053] Specifically, in combination Figures 7-9 As shown, the box body 21 of the scrap box 20 is detachably connected with the pencil sharpener main body 10. The conveying member 22 has a spiral blade 22a.

[0054] Further, in the embodiment, the pencil sharpener body 10 comprises a housing 11, a power source 12, a gear set 13, a support frame 14, a cutter holder 15, a pencil feeding assembly 16 and a connecting gear 17. The support frame 14 is arranged in the inner cavity 11a of the housing 11, the power source 12 is an electric motor, the electric motor, the gear set 13 and the connecting gear 17 are all mounted on the support frame 14. One end of the cutter holder 15 is connected with a gear in the gear set 13 through a spline, and the other end is connected with the pencil feeding assembly 16. The cutter holder 15 is provided with a hob 15a, and the cutter holder 15 is arranged obliquely. The body 10 is externally provided with a mounting groove 11b, and a waste box 20 is detachably mounted in the groove, and the side wall of the groove is provided with a jack 11c. When the waste box 20 is placed in the mounting groove 11b, the upper end opening of the waste box 20 is located below the hob 15a, i.e. directly below the cutting position.

[0055] Specifically, in combination with Figures 5-10 As shown in the figure, in the embodiment, the conveying member 22 is rotatably mounted in the box body 21 of the waste box 20 through a connecting member 23, the connecting member 23 has a connecting portion 23a for connecting the power source 12; the connecting member 23 has a limiting portion 23b for limiting position of the connecting member 23 in the axial direction; the connecting member 23 has a buckle portion 23c which passes through a connecting column 21b on the box body 21 and is buckled with the conveying member 22.

[0056] Further, in the embodiment, the waste box 20 is provided with a connecting column 21b on the side close to the pencil sharpener body 10, and the connecting column 21b is located in the waste collecting cavity 21a of the waste box 20, and the connecting column 21b is a hollow structure. The conveying member 22 has a spiral blade 22a and an inner hole 22b, the inner diameter of the inner hole 22b is matched with the outer diameter of the connecting column 21b, so that the conveying member 22 can be rotatably matched with the connecting column 21b.
