Description

Technical Field

[0001] The utility model relates to the technical field of paper feeding deviation correction, in particular to an automatic deviation correction mechanism for a paper feeding machine. Background Art

[0002] The paper is transported by the paper feed roller driving the paper feed line belt. Only when the conveyor line belt runs smoothly, at a uniform speed, with close tension and without deviation, can the paper be transported stably. During the transportation process, the paper is prone to deviate due to the influence of tension. The raw materials of cigarette packaging boxes need to be printed during the production process. However, when the raw materials deviate during the transportation process, the printed pattern will be misaligned.

[0003] The patent with application number 202123241313.0 discloses an automatic deviation correction mechanism for a paper feed belt, including a first paper feed roller and a second paper feed roller arranged in parallel, the first paper feed roller and the second paper feed roller are both rotatably connected to a first bracket, a first tensioning roller and a second tensioning roller are connected to the first bracket, a first sensor for detecting the position of the paper feed belt is provided on both sides of the end of the first bracket, the second tensioning roller is provided with a shaft, one end of the shaft is fixed, and the other end is movably connected to a power mechanism, the power mechanism is connected to a control mechanism, and the control mechanism is electrically connected to the first sensor.

[0004] The above technical solution uses the adjustment of the angle of the tensioning roller to correct the deviation of the paper during transportation. However, since the tension at both ends of the paper will change during the rotation of the tensioning roller, the paper will be torn during transportation. In addition, the tilted tensioning roller may correct the deviation too much, causing the paper to tilt to the other side, resulting in a poor correction effect on the paper transportation. Utility Model Content

[0005] The purpose of the utility model is to address the deficiencies in the prior art and provide an automatic deviation correction mechanism for a paper feeding machine, which achieves the function of avoiding deviation correction tearing and excessive deviation correction by means of an elastically arranged deviation correction plate structure in cooperation with a slide groove structure of a limit deviation correction plate, thereby solving the problem of poor deviation correction effect in paper conveying.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic deviation correction mechanism of a paper feeding machinery, comprising a symmetrically arranged mounting plate and a deviation correction roller rotatably arranged between the two mounting plates, characterized in that a winding roller and a conveying roller are rotatably arranged at both ends of the mounting plate, sliding grooves are opened on both sides of the outer wall of the deviation correction roller, and a deviation correction plate engaged with the sliding groove is symmetrically slidably sleeved at the center position of the deviation correction roller, wherein adjustment plates are adjustably installed at both ends of the deviation correction roller, and a spring sleeved on the deviation correction roller is installed between the adjustment plate and the deviation correction plate.

[0007] Preferably, positioning rollers are symmetrically installed at the center of the mounting plate, and positioning plates are fixedly sleeved at both ends of the two positioning rollers.

[0008] Furthermore, a printing device far away from the deviation-correcting roller is fixed between the two mounting plates, and a through groove is formed at the bottom end of the printing device.

[0009] Furthermore, a packaging box paper material is arranged between the conveying roller and the winding roller, and the packaging box paper material sequentially contacts the outer wall of the deviation correcting roller, the positioning roller and the inner wall of the through groove.

[0010] Furthermore, a fixed roller is arranged above the deflection-correcting roller, the fixed roller is fixedly connected to the mounting plate, and the distance between the fixed roller and the deflection-correcting plate is 1-2 mm.

[0011] Furthermore, a motor is fixed to the side wall of the mounting plate, and a shaft of the motor is fixedly connected to the winding roller.

[0012] Furthermore, a sliding portion is fixed to the inner wall of the deviation-correcting plate, and the sliding portion is inserted into the sliding groove.

[0013] Furthermore, screw holes are equidistantly provided on both sides of the outer wall of the deviation-correcting roller, and bolts threadedly inserted into the screw holes are provided on the side walls of the adjustment plate.

[0014] The beneficial effects of the utility model are:

[0015] (1) The utility model provides a deflection correction roller on the mounting plate, and deflection correction plates are slidably sleeved on both ends of the deflection correction roller. The elastic force of the spring pushes the deflection correction plate to apply pressure to the side wall of the packaging box paper material, thereby pushing the packaging box paper material for deflection correction. After the deflection correction plate pushes the packaging box paper material to correct its position, the sliding part at the bottom end abuts against the side wall of the slide groove, thereby avoiding the deflection correction plate from continuing to move and causing deflection correction misalignment. At the same time, positioning plates are fixed on both positioning rollers, and the positioning plates avoid the packaging box paper material from being misaligned again, thereby improving the deflection correction effect of the packaging box paper material conveying.

[0016] (2) The utility model has adjustment plates installed at both ends of the deflection correcting roller, and the outer wall of the deflection correcting roller is provided with a plurality of screw holes, and bolts are passed through the adjustment plates and threadedly inserted into the screw holes, so that the adjustment plates and the deflection correcting roller are kept fixed. After the bolts are unscrewed, the adjustment plates are slid and threadedly inserted into the screw holes at different positions, so that the position of the adjustment plates and the elastic force of the springs can be adjusted, thereby adjusting the deflection correcting extrusion force of the deflection correcting plates.

[0017] In summary, the utility model has the advantages of good deviation correction effect during box paper material conveying, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Embodiment 1

[0026] like Figure 1 and Figure 3As shown, the present embodiment provides an automatic deviation-correcting mechanism for a paper feeding machine, comprising a symmetrically arranged mounting plate 1 and a deviation-correcting roller 7 rotatably arranged between the two mounting plates 1, characterized in that a winding roller 8 and a conveying roller 3 are rotatably arranged at both ends of the mounting plate 1, sliding grooves 18 are provided on both sides of the outer wall of the deviation-correcting roller 7, and a deviation-correcting plate 14 engaged with the sliding groove 18 is symmetrically slidably sleeved at the center position of the deviation-correcting roller 7, wherein adjustment plates 15 are adjustably installed at both ends of the deviation-correcting roller 7, and a spring 16 sleeved on the deviation-correcting roller 7 is installed between the adjustment plate 15 and the deviation-correcting plate 14.

[0027] Positioning rollers 5 are symmetrically installed at the center of the mounting plate 1, and positioning plates 11 are fixedly sleeved at both ends of the two positioning rollers 5. A printing device 4 away from the deflection correction roller 7 is fixed between the two mounting plates 1 (the printing device 4 is a prior art and will not be described in detail here). A through slot 10 is opened at the bottom of the printing device 4, and a packaging box paper material 2 is arranged between the conveying roller 3 and the winding roller 8. The packaging box paper material 2 contacts the outer wall of the deflection correction roller 7, the positioning roller 5 and the inner wall of the through slot 10 in turn. A fixed roller 6 is arranged above the deflection correction roller 7, and the fixed roller 6 is connected to the mounting plate 1. It is fixedly connected, and the spacing between the fixed roller 6 and the correcting plate 14 is 1-2 mm. The elastic force of the spring 16 pushes the correcting plate 14 to apply pressure to the side wall of the packaging box paper material 2, thereby pushing the packaging box paper material 2 to correct the deviation. After the correcting plate 14 pushes the packaging box paper material 2 to correct its position, the sliding part 17 at its bottom abuts against the side wall of the slide groove 18, thereby avoiding the correction plate 14 from continuing to move and causing correction misalignment. At the same time, positioning plates 11 are fixed on the two positioning rollers 5, and the positioning plates 11 prevent the packaging box paper material 2 from being misaligned again.

[0028] Embodiment 2

[0029] like Figure 2 and Figure 4 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment is different from the first embodiment in that: a motor 9 is fixed to the side wall of the mounting plate 1, the shaft of the motor 9 is fixedly connected to the winding roller 8, a sliding portion 17 is fixed to the inner wall of the deviation correction plate 14, the sliding portion 17 is inserted in the slide groove 18, screw holes 13 are equidistantly provided on both sides of the outer wall of the deviation correction roller 7, and bolts 12 threadedly inserted in the screw holes 13 are provided on the side wall of the adjustment plate 15. After the bolts 12 are unscrewed, the adjustment plate 15 is slid and threadedly inserted in the screw holes 13 at different positions, so as to adjust the position of the adjustment plate 15 and the elastic force of the spring 16, and then adjust the deviation correction extrusion force of the deviation correction plate 14.

[0030] Working steps

[0031] Step 1. When in use, start the motor 9 to make the winding roller 8 drive the packaging box paper material 2 to move and wind up the processed paper material. During the processing, the elastic force of the spring 16 pushes the correction plate 14 to apply pressure to the side wall of the packaging box paper material 2, thereby pushing the packaging box paper material 2 to correct the deviation. After the correction plate 14 pushes the packaging box paper material 2 to correct its position, the sliding part 17 at its bottom abuts against the side wall of the slide groove 18, thereby avoiding the correction plate 14 from continuing to move and causing correction misalignment. The corrected packaging box paper material 2 is transported between the two positioning rollers 5. The positioning plate 11 on the positioning roller 5 avoids the packaging box paper material 2 from being misaligned again, thereby improving the correction effect of the transportation of the packaging box paper material 2.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
