Description

Automatic pen cutting machine

The invention relates to a pencil sharpener, in particular to a pencil sharpener which automatically feeds a pen.

The existing pencil sharpener comprises a body, a pinch pen mechanism, a tool holder and a chip box. If it is a hand crank, it further comprises a handle, the body is hollow, and the pin feeding mechanism And disposed on the front side of the body, the tool holder is disposed in the body and driven by the rotary handle, and the chip container is disposed in the body.

In use, the user first pulls the pinch pen mechanism, moves the pinch pen mechanism away from the body, and is clamped to the body by a limiting rod, and then puts a pencil into the clip. In the pinch pen mechanism, the user grips and rotates the handle to drive the tool holder to rotate, and when the tool holder rotates, the limit bar is touched, so that the pinch pen mechanism can be released and can be moved. Moving in the direction of the body to drive the pencil to advance toward the tool holder by the pinch pen mechanism, and finally, when the pencil cutting is completed, the user operates the pinch mechanism again to make the pinch mechanism Remove the pencil and remove the pencil.

When the existing hand-held pencil sharpener is used, since the clip pen mechanism is first operated to move and position away from the body, the pencil is clamped, and when the user turns the handle, the The tool holder can only actuate the limit rod to drive the pinning pen mechanism to move the pencil in the direction of the body to feed the pen, so that the pencil is cut by the tool of the tool holder. Therefore, the existing pencil sharpener utilizes the clip. The pen is simultaneously sent by pen to perform the pen-shaving, which not only has complicated components, but also has many operation steps when cutting the pencil, which makes the existing pencil sharpener inconvenient to use; further, the user may operate the pin-feed pen mechanism. Because of the accidental pinching of the hand in the direction of the body, there is a safety concern; in addition, the pinning pen mechanism is not located in the body, which is not conducive to the modularization of the whole component, so that the existing pencil sharpener has High production costs, the lack of which is necessary to improve.

In order to solve the above problems of the existing pencil sharpener, the main object of the present invention is to provide a pencil sharpener that realizes automatic feeding by using automatic feed. When used, the knife seat assembly automatically moves relative to the fixed pencil to cut the pencil. Achieve the role of automatic pen.

The automatic pen-printing machine of the present invention comprises: a body having a first wall portion and a second wall portion disposed oppositely, and a pen hole is formed in the first wall portion; An assembly disposed in the body, the holder assembly being linearly movable in a direction between the first wall portion and the second wall portion toward and away from the pen hole; a cutter module disposed in the holder assembly and moving synchronously with the holder assembly, and the cutter module is driven by a driving device to rotate relative to the holder assembly, the cutter module is provided with a a cutter; and an elastic unit disposed between the body and the seat assembly to provide an elastic force that urges the seat assembly to return to its original position.

According to the above technical means, the automatic pen-printing machine of the present invention only needs to insert a pencil into the holder assembly, so that the pencil pushes the holder assembly to move away from the pen hole, and then By driving the cutter module with the driving device, the pencil can be cut. When the pencil is shortened, the elastic unit drives the holder assembly to move toward the pen hole to supplement the length of the pencil being shortened. The invention discloses that the automatic pen-cutting pen can realize the effect of automatic pen-feeding by using automatic feeding, and the operation steps are few, so the use is relatively simple, and the conventional rebound-type pin-feed pen mechanism is discarded, so that the user is not pinched. Fingers with high security. Moreover, since the present invention does not need to provide a pinch pen mechanism for external pulling, the tool holder assembly is disposed in the body, which can facilitate the modularization of the whole component of the pencil sharpener, and enhance the practicability and production efficiency. In addition, when the invention is applied to the electric pencil sharpener, the complicated automatic automatic pen feeding mechanism is not required, and the advancement of the cutter can be utilized to achieve the automatic feeding effect, which can effectively simplify the structure and reduce the cost.
