As described with reference to fig. 2 and 3, the paper guide 100 is mainly composed of two air pipes which can be ventilated and form air flow, and the two air pipes are respectively an air duct 110 and a paper supporting air pipe 120, which are arranged side by side. The paper guide pipe 110 and the paper supporting pipe 120 can be round pipes, square pipes or other pipe fittings, and only the inside of the paper guide pipe is required to be provided with ventilation space, in the embodiment, the main body of the paper guide pipe 110 is a rectangular pipe which is formed by welding plate members, and the function of the rectangular pipe is related to the following functions; the paper supporting air pipe 120 adopts a round pipe, one end of the paper supporting air pipe is an air inlet end, and the paper supporting air pipe can be externally connected with other air pipelines, and the other end of the paper supporting air pipe is closed.

It should be noted that, an included angle is formed between the axis of the air guiding hole 112 and the axis of the paper supporting hole 121, in the paper guiding process, the air in the paper supporting air pipe 120 blows air flow through the paper supporting hole 121 to support the paper, and the air in the paper guiding air pipe 110 guides the supported paper to the direction through the air guiding hole 112, so that the paper guiding is accurately completed. As a preferred arrangement, in this embodiment, the axis of the paper supporting air hole 121 passes through the axis of the paper supporting air pipe 120, and the guiding air hole 112 on the paper guiding air pipe 110 is an inclined hole, the axis of the guiding air hole 112 intersects with the axis of the paper supporting air pipe 120, which is a better relative arrangement relationship between two holes obtained by long-term practice groping of the applicant, and the included angle between the axis of the guiding air hole 112 and the axis of the paper supporting air hole 121 can be adjusted by controlling the rotation of the paper supporting air pipe 120; meanwhile, in order to match the relation between the position and the angle of the air hole, the diameter of the air hole 112 is controlled to be about 15 mm, the aperture of the paper supporting air hole 121 is better when the aperture is about 35 mm, the paper guiding process ensures that uniform air flow is generated, and the paper guiding performance is better.
As a further improvement, the paper guide tube 110 is provided with a guide plate 111, the guide air holes 112 are formed in the guide plate 111, and the axis of the guide air holes 112 is not perpendicular to the surface of the guide plate 111, and has an inclination angle. The front end of the guide plate 111 extends outwards to form a larger supporting surface, and the rear end of the guide plate extends to a position close to the paper supporting air hole 121 of the paper supporting air pipe 120, so that the guide air hole 112 is closely connected with the paper supporting air hole 121. When the paper is guided, the guide air holes 112 of the paper guide air pipe 110 and the paper supporting air holes 121 of the paper supporting air pipe 120 are arranged between the guide plate 111 and the paper, so that an air flow space is formed between the guide plate 111 and the paper, the paper is guided in a relatively uniform manner and better in a relatively large area of the paper surface, more excellent paper guiding stability and accuracy are achieved, the paper surface is better protected, and damage is avoided. Meanwhile, the paper guide pipe 110 is provided with a guide air inlet joint 113, the air source can be connected through other pipelines, and the guide air inlet joint 113 is positioned in the middle of a row of guide air holes 112 arranged on the paper guide pipe 110, so that the air flow of each guide air hole 112 is relatively uniform when the paper guide pipe 110 is ventilated.

In this embodiment, one end of the paper guide pipe 110 is fixedly connected with the supporting plate 140 by welding, the supporting plate 140 is provided with a mounting hole, and the air inlet end of the paper guide pipe 120 passes through the mounting hole and is locked by a screw, so that the angle can be conveniently adjusted, and the rotation in the work can be fixedly limited; the other end of the paper guide pipe 110 and the tail end of the paper supporting pipe 120 are detachably mounted on the connecting plate 130 through screws, so that the paper guide pipe 110 and the paper supporting pipe 120 are organically combined into a whole, and the paper guiding angle is convenient to adjust.
As can be seen from fig. 1, the driving mechanism mainly comprises a connecting member 200, a guide rod 300, a guide slide 400 and a driving cylinder. Wherein the guide bar 300 is supported and arranged on the mounting seat 500 through the guide slide 400, that is, the guide slide 400 is fixed on the mounting seat 500 through bolts, the guide bar 300 is slidingly arranged in the guide slide 400, and thus the guide bar 300 can do telescopic movement in the guide slide 400; one end of the guide rod 300 is connected with the paper guiding component 100 through the connecting piece 200, the other end of the guide rod 300 is connected with the driving cylinder, and the driving cylinder drives the guide rod 300 to stretch and retract, so that pushing or retracting actions of the paper guiding component 100 are realized.
As shown in fig. 2, the connecting member 200 has a connecting sleeve 210 and an adjusting plate 220 at both ends thereof, respectively. The air inlet end of the paper supporting air pipe 120 passes through the connecting sleeve 210, is locked by matching the screw threads on the air inlet end of the paper supporting air pipe 120 with the screw nuts, and tightly pushes the screw nuts by the set screws, so that the paper guiding component 100 caused by loosening is prevented from rotating.

Here, the reversing valve 610 is a two-position four-way electromagnetic reversing valve, and can be controlled to perform reversing action by a control circuit controller.
In addition, since the paper guiding component 100 needs to move back and forth in use, and the paper guiding air pipe 110 and the paper supporting air pipe 120 need to be connected with an air source through the pipeline, the connecting pipeline is dragged to rub back and forth, which is not beneficial to the protection of the connecting pipeline, and the problem of air leakage may occur. Therefore, the guide bar 300 of this embodiment is provided with the guide block 310, the corresponding guide slide 400 is provided with the guide groove matched with the guide block 310, the guide block 310 is provided with two hard tubes 700 through the tube clamps 710, and the two hard tubes 700 are respectively connected with the paper guide air tube 110 and the paper supporting air tube 120 through the hose, so that the hard tubes 700 are relatively static relative to the paper guide air tube 110 and the paper supporting air tube 120, and the connected hose is not pulled, thereby avoiding the problems described above.
In use, when paper is required to be guided, the reversing valve 610 is powered on, the driving cylinder pushes the paper guiding component 100 to a working position, and the air source ventilates the paper guiding air pipe 110 and the paper supporting air pipe 120 to guide paper; after the paper feeding operation is completed, the air supply is stopped, the reversing valve 610 reverses, and the driving cylinder drives the paper feeding part 100 to return to the initial position, and waits for the next paper feeding operation.
