Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "provided," "connected," and the like are to be construed broadly, such as "connected," which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1, an automatic paper cutting machine comprises a frame 1, wherein a paper winding shaft 7 is arranged on the frame 1, the paper winding shaft is used for placing a paper tube formed by rolling paper to be cut, the paper to be cut is wound around a lower roller 2 and moves to a paper cutting table 3, the paper winding shaft 7 is arranged above the roller 2 and mainly considers that the paper to be cut tends to move downwards due to self gravity, and therefore the paper to be cut moves more smoothly.

Wherein, cylinder 2 includes driven cylinder 22 and the initiative cylinder 21 that sets up from top to bottom, and initiative cylinder 21 is driven by the motor, treats that the paper once moves to cut paper platform 3 through driven cylinder 22, initiative cylinder 21, sets up driven cylinder 22 and has certain tensioning and increase frictional effect to the paper that treats, prevents to treat that the paper skids on cylinder 2.

Referring to fig. 2 and 4, the frame is further fixedly provided with a paper cutting table 3, the top of the paper cutting table 3 is horizontally disposed, and a rodless cylinder 10 is disposed below the top of the paper cutting table 3. The top of the rodless cylinder 10 is provided with a slide rail 4, the rodless cylinder 10 drives the slide block 5 to horizontally slide along the slide rail 4, the slide block 5 is provided with a cutting tool 6, the top of the paper cutting table 3 is provided with a slide groove 31, and the cutting tool 6 penetrates through the slide groove 31 from the lower part and is used for cutting paper to be cut on the paper cutting table 3.

As shown in fig. 5, the number of the cutting tools 6 is two, and the two back ends 61 of the cutting tools 6 are oppositely arranged, so that the two blade ends 62 are arranged outwards, and the blade ends 62 are arranged upwards in an inclined manner, which is more beneficial to cutting paper and ensures smooth cutting. When slider 5 moves from left to right, cutting tool 6 on right side cuts the paper, and when slider 5 moved from right to left, left cutting tool 6 cut the paper to compare in the prior art and only saved the step that slider 5 reset of the cutter of one side cut paper, improved cutting efficiency.

Referring to fig. 1 and 3, the frame 1 is further provided with a paper pressing device for fixing paper to be cut, the paper pressing device includes a horizontal beam 11 fixed on the frame, the beam 11 is fixedly provided with air cylinders, the number of the air cylinders 8 is not limited, and the paper pressing device is adaptively adjusted according to the length and weight of the lower pressing plate 9. The air cylinder 8 drives the lower pressing plate 9 to move up and down, and the pressing plate 9 can be pressed on the top of the paper cutting table to keep the paper to be cut fixed. The bottom of the pressing plate 9 is provided with a stroke groove 91 corresponding to the sliding groove 31, and the stroke groove 91 can accommodate the cutting tool 6 extending from the lower part to move in the stroke groove, so that the work of the cutting tool 6 is not influenced while the paper to be cut is ensured to be fixed.

In the embodiment, the rodless cylinder 10 is adopted to replace a traditional screw motor structure for driving the cutter 6 to move, and the stability of the transmission of the rodless cylinder 10 is high, so that the cutter 6 can cut paper from two directions when reciprocating, and compared with the mode that the transmission motor drives the cutter, the requirement on the performance of the cutter is low, common cutter materials and structures can be adopted, and the cost is saved.

The specific working process is as follows: firstly, the motor drives the driving roller 21 to rotate, so that the paper to be cut is driven to move to the paper cutting table 3, after the paper is moved to a specified length, the motor stops rotating, the cylinder 8 drives the pressing plate 9 to press down, then the rodless cylinder 10 drives the sliding block 5 to move, so that the cutting tool 6 cuts the paper to be cut from left to right, after the cutting is completed, the cylinder 8 lifts the pressing plate 9, the motor rotates again, the paper to be cut continues to move, after the specified length is reached, the motor stops rotating, the cylinder 8 drives the pressing plate 9 to press down, the rodless cylinder 10 drives the sliding block to move, so that the cutting tool cuts the paper to be cut from right to left, and then the operations are repeated.

The foregoing shows and describes the basic principles and principal features of the invention, together with the advantages thereof. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only illustrative of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the present invention, and all such changes and modifications fall within the scope of the present invention as claimed.
