[0007] As a preferred embodiment, guide rods that penetrate the sidewall of the outer frame are fixed near both ends on the outer side of the guide plate, and an adjusting screw that is threaded through the sidewall of the outer frame is rotatably installed in the middle part of the outer side of the guide plate.

[0008] As a preferred embodiment, a connector is fixed to one end of the adjusting screw facing the guide plate, and a rotating sleeve is fitted on the outside of the connector, with the rotating sleeve being fixedly connected to the guide plate.

[0009] As a preferred embodiment, the cutting mechanism includes a cutting motor, a support block is fixed to the lower side of the cutting motor, and a mounting plate is fixed to the lower side of the support block. A cutting blade is fixed on the output shaft of the cutting motor.

[0010] As a preferred embodiment, the pressing mechanism includes an electric telescopic rod fixed to the lower surface of the top plate, a fixing frame fixed to the lower end of the electric telescopic rod, and a pressure roller fixed to the inner side of the fixing frame near the lower end.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The paperboard is fed by a feeding roller during cutting, and guided by guide plates on the front and rear sides. The guide plates can be adjusted to adjust the direction according to the size of the paperboard, which provides good flexibility in use. Attached Figure Description

Detailed Implementation

[0019] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0021] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0022] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0023] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0024] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

The top rod of the electric telescopic rod 31 drives the fixed frame 33 to drive the pressure roller 32 to descend and press the cardboard 6 during cutting and conveying.

[0030] In this embodiment, when the cardboard 6 is cut, the cardboard 6 is placed on the feeding roller 5. At this time, the feeding roller 5 conveys the cardboard 6. At this time, the top rod of the electric telescopic rod 31 drives the fixing frame 33 to drive the pressure roller 32 to descend and press the cardboard 6 during cutting and conveying. The feeding roller 5 conveys the cardboard 6, and the conveyed cardboard 6 is cut when it passes the cutting blade 72, thereby completing the cutting of the cardboard.

[0031] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments.
