Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides an electric paper punch 100, which includes a base 10, a bracket 20, a punch 30 and a micro negative pressure air pump 40.
The base 10 includes a base body 11 and a cover plate 12 covering the base body 11, the cover plate 12 is detachably connected to the base body 11, and the cover plate 12 is matched with the base body 11 to form a closed cavity 13.
The upper surface of pedestal 11 is sunken to be formed with the apron mounting groove to the lower surface direction, pedestal 11 corresponds the position of apron mounting groove bottom to apron mounting groove inner protrusion is formed with bearing part 15, apron 12 directly place in on bearing part 15, the upper surface of apron 12 with the upper surface of pedestal 11 is located the coplanar. When punching, paper is placed on the cover plate 12, preferably, the cover plate 12 is of a steel structure, and the paper can be directly fixed on the cover plate 12 by adopting a magnetic block, so that the use is convenient.
The miniature negative pressure air pump 40 is communicated with the cavity 12 and used for pumping air to the cavity 12 so as to form negative pressure in the cavity 12. The miniature negative pressure air pump 40 is fixed on the back of the base 11. Preferably, a sealing gasket 14 is arranged at the connecting position of the cover plate 12 and the seat body 11, so that the pressure maintaining effect can be achieved. It can be understood that, due to the negative pressure in the cavity 13, the cover plate 12 can be in close contact with the base 11 under the action of atmospheric pressure and its own gravity. It should be noted that the "upper surface" is a surface above the corresponding structure in fig. 2, and the "lower surface" is a surface below the corresponding structure in fig. 2.
The bracket 20 is fixed to the base 10 and is used for fixedly mounting the hole puncher 30. The bracket 20 includes two vertical plates 21 fixed to the base 10 and arranged in parallel at intervals and a horizontal plate 22 connecting the two vertical plates 21, and the hole puncher 30 is mounted on the horizontal plate 22. The vertical plate 21 is concavely formed with a guide groove 210, and the guide groove 210 extends in the vertical direction. Note that the vertical direction is the height direction of the vertical plate 21.
The hole puncher 30 comprises a cylinder 31 fixed on the transverse plate 22, a guide rod 32 connected with the shaft of the cylinder 31, a movable plate 33 fixed at the tail end of the guide rod 32, and a hole punching tool bit 34 fixed at the bottom end of the movable plate 33. The cylinder 31 drives the guide rod 32, the movable plate 33 and the punching head 34 to move linearly in a vertical direction. The structure and the theory of use of cylinder 31 belong to the conventional technical means in this field, the utility model discloses do not describe repeatedly to this, simultaneously, the model of cylinder 31 is selected as required.
A protrusion 331 is formed at a position of the movable plate 33 corresponding to the guide slot 210, and the protrusion 331 is correspondingly limited in the guide slot 210. The guide groove 210 serves as a guide limiting function, and can limit the deviation of the movable plate 33 in other directions, so that the punching tool bit 34 always moves linearly in the vertical direction.
Further, a through hole 120 penetrates through the cover plate 12 at a position corresponding to the punching tool bit 34, and the through hole 120 communicates the cavity 13 with the outside. The central axis of the punching head 34 and the central axis of the through hole 120 are located on the same straight line, the diameter of the punching head 34 is matched with that of the through hole 120, and the punching head 34 can correspondingly extend into the through hole 120. Preferably, one end of the punching head 34 close to the through hole 120 is recessed towards the direction away from the through hole 120 to form a conical punching surface 341, and the punching surface 341 and the outer circumferential surface of the punching head 34 cooperate to form a positive rake angle cutting edge, which is sharp, so that a larger stress action can be generated, and the paper can be conveniently cut.
During the use, place the paper in on the apron 12, the cylinder 31 drive punch the downward motion of tool bit 34, apply the effort to the paper surface, the blade of tool bit 34 that punches with the last edge cooperation of through-hole 120 produces crisscross shearing force, accomplishes the punching press cutting to the paper and punches, and the waste material that produces after punching is along with tool bit 34 that punches continues the downstream entering in the negative pressure chamber 13, because be the negative pressure in the cavity 13, make there is pressure differential in the inside and outside both sides of through-hole 120, the paper piece that produces in the punching press cutting process also can the pressure differential effect downstream down, and then the internal absorption advances in the negative pressure chamber 13.
Because the cover plate 12 is detachably connected with the base body 11, when the waste materials and the scraps in the negative pressure cavity 13 are gathered to a certain degree, the cover plate 12 can be opened to clean the waste materials and the scraps in the negative pressure cavity 13.
It should be noted that, both the cylinder 31 and the micro negative pressure cylinder 40 need to be electrically connected to an external power source. The cylinder 31 and the miniature negative pressure flag pole 40 can also be connected by an electrical control terminal, the operation is controlled by the electrical control terminal, and the connection and control process of the related control circuit are conventional technical means in the field, which is not described in detail in this embodiment.
Compared with the prior art, in the electric paper puncher provided by the utility model, the cover plate is detachably connected with the base body, a closed cavity is formed between the cover plate and the base body in a matching way, the cover plate is provided with a through hole at the position corresponding to the punching tool bit, waste materials which are punched and cut are punched into the cavity, the waste materials can be collected, and meanwhile, the cavity is pumped into negative pressure by the miniature negative pressure pump, so that the waste materials which are generated in the punching process can be absorbed; moreover, the electric paper punching machine provided by the application is an automatic operation device, and compared with a manual paper punching machine, the punching efficiency can be greatly increased.
The above embodiments of the present invention are only described, and it should be noted that, for those skilled in the art, modifications can be made without departing from the inventive concept, but these all fall into the protection scope of the present invention.
