[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Embodiment 1

[0024] The present invention provides a technical solution: a folding machine for printing paper with uniform folding, comprising a workbench 1, a first mounting seat 31 is fixedly connected to the workbench 1, a printing mechanism for printing paper is arranged on the first mounting seat 31, the printing mechanism comprises a first rotating shaft 251 fixedly connected to the first mounting seat 31, a printing roller 25 is fixedly connected to the first rotating shaft 251, a motor 2 is fixedly connected to the workbench 1, a driving shaft 24 is fixedly connected to the output end of the motor 2, a non-complete gear 21 is fixedly connected to the driving shaft 24, and the driving shaft A sector gear 22 that cooperates with the incomplete gear 21 is rotatably connected to 24, a first mounting column 211 is fixedly connected to the incomplete gear 21, a second mounting column 221 is fixedly connected to the sector gear 22, a tension spring 23 is fixedly connected between the second mounting column 221 and the first mounting column 211, a full-tooth gear 252 is fixedly connected to the first rotating shaft 251, the incomplete gear 21 and the sector gear 22 are alternately meshed with the full-tooth gear 252, and the friction force between the sector gear 22 and the full-tooth gear 252 is greater than the tension of the tension spring 23.

[0025] Reference Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7 , place the paper on the workbench 1 and make one end of the paper pass between the printing roller 25 and the rotating roller 26, start the motor 2, and then the driving shaft 24 connected to the output end of the motor 2 rotates, and then the incomplete gear 21 fixedly connected to the driving shaft 24 rotates synchronously with the driving shaft 24. Since the fan gear 22 is rotatably connected to the driving shaft 24, and the fan gear 22 is connected to the incomplete gear 21 through the tension spring 23, the incomplete gear 21 can rely on the tension of the tension spring 23 to drive the fan gear 22 and the incomplete gear 21 to rotate synchronously when following the rotation of the driving shaft 24. When the incomplete gear 21 and the fan gear 22 rotate, they can alternately mesh with the full-tooth gear 252, and the steering of the incomplete gear 21 is Figure 4In the state, the sector gear 22 rotates clockwise, and then when the teeth on the incomplete gear 21 do not contact the teeth on the full-tooth gear 252, the teeth of the sector gear 22 mesh with the teeth on the full-tooth gear 252. Since the friction force between the sector gear 22 and the full-tooth gear 252 is greater than the tension of the tension spring 23, the sector gear 22 stops rotating due to the friction force between the sector gear 22 and the full-tooth gear 252. At this time, the sector gear 22 will not drive the full-tooth gear 252 to rotate, and when the incomplete gear 21 continues to rotate, the incomplete gear 21 will push the sector gear 22, so that the sector gear 22 overcomes the sector gear 22. The friction between the full-tooth gear 252 and the full-tooth gear 252 drives the full-tooth gear 252 to rotate. The driving shaft 24 arranged at the output end of the motor 2 can rotate continuously, and the first rotating shaft 251 fixedly connected to the full-tooth gear 252 can intermittently rotate following the full-tooth gear 252, and then the printing roller 25 fixedly connected to the first rotating shaft 251 can rotate intermittently, so that the paper can be intermittently printed and transported. Since the driving shaft 24 is always in a rotating state, the stirring rod 241 fixedly connected to the driving shaft 24 can continuously stir the ink in the ink cartridge 3 to prevent the ink from solidifying and settling.

[0026] The printing mechanism also includes a roller 26 rotatably connected to the workbench 1 and cooperating with the printing roller 25, a second rotating shaft 261 is fixedly connected to the roller 26, the second rotating shaft 261 is rotatably connected to the workbench 1, an ink cartridge 3 for providing ink to the printing roller 25 is fixedly connected to the first mounting seat 31, a stirring rod 241 is fixedly connected to the driving shaft 24, the stirring rod 241 is rotatably connected to the ink cartridge 3, an adding port 32 for adding ink to the ink cartridge 3 is provided on the ink cartridge 3, and a cutting mechanism for cutting off the printed paper is provided on the printing mechanism. The cutting mechanism includes a cutting knife 4, a second mounting seat 42 is fixedly connected to the workbench 1, a mounting rod 41 is fixedly connected to the cutting knife 4, the mounting rod 41 is rotatably connected to the second mounting seat 42, a pressure rod 411 is fixedly connected to the mounting rod 41, a lever 242 is fixedly connected to the driving shaft 24, the lever 242 and the pressure rod 411 are intermittently abutted, the cutting mechanism also includes a torsion spring 422, a cylinder 421 coaxial with the mounting rod 41 is fixedly connected to the second mounting seat 42, and the cylinder 421 is connected to the mounting rod 41 through the torsion spring 422.

[0027] Reference Figure 1 , Figure 2 and 5When the lever 242 on the driving shaft 24 contacts the pressure rod 411 on the mounting rod 41, the sector gear 22 just meshes with the full-tooth gear 252. At this time, the full-tooth gear 252 does not rotate, and the paper is not transported. At this time, the lever 242 applies pressure to the pressure rod 411. Since the pressure rod 411 is fixedly connected to the mounting rod 41, when the pressure rod 411 is pressed by the lever 242, the mounting rod 41 will rotate. Then the rotating mounting rod 41 drives the cutting knife 4 fixedly connected to the mounting rod 41 to rotate and approach the paper to cut the paper. As the driving shaft 24 continues to rotate, the lever fixedly connected to the driving shaft 24 242 is away from the pressure rod 411. At this time, the mounting rod 41 rotates to the original position under the action of the torsion spring 422, away from the paper. At this time, the paper is cut. Before the paper is cut, it has been pushed to the first conveying roller 6 and the second conveying roller 61 by the printing roller 25, and the cut paper is displaced between the pressure ring 531 and the first groove 532, and the driven wheel 64 on the second conveying roller 61 is connected with the driving wheel 262 on the rotating roller 26. When the printing roller 25 drives the rotating roller 26 to rotate, the rotating roller 26 can drive the driven wheel 64 to rotate through the driving wheel 262, and then the second conveying roller 61 rotates, and then the cut paper can be transported.

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5When the cutting knife 4 rotates to cut the paper, the tilting rod 412 located on the opposite side of the pressure rod 411 rotates in the direction away from the workbench 1, and then the sliding column 413 on the tilting rod 412 slides in the sliding groove on the first connecting rod 51, so that the first connecting rod 51 can rotate in the direction away from the workbench 1 with the rotating column 511 as the center, and then the point connected to the first connecting rod 51 on the second connecting rod 52 which is rotatably connected to the first connecting rod 51 is lifted upward, and at this time, the mounting shaft 53 fixedly connected to the second connecting rod 52 slides on the mounting bar 5 in the direction close to the cutting knife 4, and at this time, the pressing ring 531 on the mounting shaft 53 rolls in the first groove 532, and since the cut paper is located between the pressing ring 531 and the first groove 532, when the pressing ring 531 rolls, a crease can be pressed on the paper, making it easy to fold the paper.

[0031] The folding mechanism is provided with a drying mechanism for air-drying the folded paper, the drying mechanism includes a mounting cylinder 54 rotatably connected to the mounting shaft 53, the mounting cylinder 54 is fixedly connected to a blade 542 and a gear ring 541, the mounting bar 5 is fixedly connected to a rack 543, and the gear ring 541 is meshed with the rack 543.

[0032] Reference Figure 1 and Figure 2 When the mounting shaft 53 slides in the slide groove on the mounting strip 5, the gear ring 541 connected to the mounting shaft 53 rotates to engage with the rack 543 on the rack 543 mounting strip 5, and then the gear ring 541 can rotate about the center of the mounting shaft 53 when following the movement of the mounting shaft 53, and then the mounting cylinder 54 fixedly connected to the gear ring 541 rotates, and at this time, the blade 542 fixedly connected to the mounting cylinder 54 rotates to blow air to the printed paper to accelerate the drying of the ink on the paper.

[0033] Embodiment 3

[0034] On the basis of Example 2, further, the printing mechanism is provided with an output mechanism for outputting the folded paper, the output mechanism includes a first conveying roller 6 and a second conveying roller 61, a third mounting seat 11 is fixedly connected to the workbench 1, a first rotating rod 62 is fixedly connected to the first conveying roller 6 and is rotatably connected to the third mounting seat 11 through the first rotating rod 62, a second conveying roller 61 is fixedly connected to a second rotating rod 63, and the second rotating rod 63 is rotatably connected to the workbench 1, a second groove 65 matching the first groove 532 is provided on the first conveying roller 6 and the second conveying roller 61, a driving wheel 262 is fixedly connected to the second rotating shaft 261, a driven wheel 64 is fixedly connected to the second rotating rod 63, and the driving wheel 262 is transmission-connected to the driven wheel 64 through a belt.

[0035] Reference Figure 1-Figure 3The folded paper is conveyed by the first conveyor roller 6 and the second conveyor roller 61 for the next step of binding. The second groove 65 on the first conveyor roller 6 and the second conveyor roller 61 corresponds to the first groove 532, so that the crease on the paper will not be flattened by the first conveyor roller 6 and the second conveyor roller 61 when the paper is conveyed by the first conveyor roller 6 and the second conveyor roller 61.

[0036] Working principle: When using the folding machine for printing paper with uniform folding, the paper is placed on the workbench 1 and one end of the paper is passed between the printing roller 25 and the rotating roller 26, and the motor 2 is started. At this time, the driving shaft 24 connected to the output end of the motor 2 rotates, and then the incomplete gear 21 fixedly connected to the driving shaft 24 rotates synchronously with the driving shaft 24. Since the fan gear 22 is rotatably connected to the driving shaft 24, and the fan gear 22 is connected to the incomplete gear 21 through the tension spring 23, the incomplete gear 21 can rely on the tension of the tension spring 23 to drive the fan gear 22 and the incomplete gear 21 to rotate synchronously when following the rotation of the driving shaft 24. When the incomplete gear 21 and the fan gear 22 rotate, they can alternately mesh with the full-tooth gear 252, and the steering of the incomplete gear 21 is Figure 4 In the state, the gear 21 rotates clockwise, and then when the teeth on the incomplete gear 21 do not contact the teeth on the full-tooth gear 252, the teeth of the sector gear 22 mesh with the teeth on the full-tooth gear 252. Since the friction between the sector gear 22 and the full-tooth gear 252 is greater than the tension of the tension spring 23, the sector gear 22 stops rotating due to the friction between the sector gear 22 and the full-tooth gear 252. At this time, the sector gear 22 will not drive the full-tooth gear 252 to rotate. When the incomplete gear 21 continues to rotate, the incomplete gear 21 will push the sector gear 22, so that the sector gear 22 overcomes the friction between the sector gear 22 and the full-tooth gear 252 and drives the full-tooth gear 252 to rotate.

[0037] In summary, the driving shaft 24 disposed at the output end of the motor 2 can rotate continuously, and the first rotating shaft 251 fixedly connected to the full-tooth gear 252 can intermittently rotate following the full-tooth gear 252, and thus the printing roller 25 fixedly connected to the first rotating shaft 251 can rotate intermittently, and thus the paper can be intermittently printed and transported. Since the driving shaft 24 is always in a rotating state, the stirring rod 241 fixedly connected to the driving shaft 24 can continuously stir the ink in the ink cartridge 3 to prevent the ink from solidifying and settling.

[0038] When the lever 242 on the driving shaft 24 contacts the pressure rod 411 on the mounting rod 41, the sector gear 22 just meshes with the full-tooth gear 252. At this time, the full-tooth gear 252 does not rotate, and the paper is not transported. At this time, the lever 242 applies pressure to the pressure rod 411. Since the pressure rod 411 is fixedly connected to the mounting rod 41, when the pressure rod 411 is pressed by the lever 242, the mounting rod 41 rotates. The rotating mounting rod 41 drives the cutting knife 4 fixedly connected to the mounting rod 41 to rotate and approach the paper to cut the paper. As the driving shaft 24 continues to rotate, the lever 242 fixedly connected to the driving shaft 24 42 is away from the pressure rod 411. At this time, the mounting rod 41 rotates to the original position under the action of the torsion spring 422, away from the paper. At this time, the paper is cut off. Before the paper is cut off, it has been pushed to the first conveying roller 6 and the second conveying roller 61 by the printing roller 25. The cut paper is displaced between the pressure ring 531 and the first groove 532, and the driven wheel 64 on the second conveying roller 61 is connected with the driving wheel 262 on the rotating roller 26. When the printing roller 25 drives the rotating roller 26 to rotate, the rotating roller 26 can drive the driven wheel 64 to rotate through the driving wheel 262, and then the second conveying roller 61 rotates, so that the cut paper can be conveyed.

[0039] Reference Figure 1 and Figure 2 When the cutting knife 4 rotates to cut the paper, the tilting rod 412 located on the opposite side of the pressure rod 411 rotates in the direction away from the workbench 1, and then the sliding column 413 on the tilting rod 412 slides in the sliding groove on the first connecting rod 51, so that the first connecting rod 51 can rotate in the direction away from the workbench 1 with the rotating column 511 as the center, and then the point connected with the first connecting rod 51 on the second connecting rod 52 which is rotatably connected to the first connecting rod 51 is lifted upward, and at this time, the mounting shaft 53 fixedly connected to the second connecting rod 52 slides on the mounting bar 5 in the direction close to the cutting knife 4, and at this time, the pressing ring 531 on the mounting shaft 53 rolls in the first groove 532, because the cut paper is located between the pressing ring 531 and the first groove 532, and then when the pressing ring 531 rolls, it can press a crease on the paper, so that the paper is easy to be folded;

[0040] When the mounting shaft 53 slides in the slide groove on the mounting strip 5, the gear ring 541 connected to the mounting shaft 53 rotates to mesh with the rack 543 on the rack 543 mounting strip 5, and then the gear ring 541 can rotate with the mounting shaft 53 as the center of the circle, and then the mounting cylinder 54 fixedly connected to the gear ring 541 rotates, and at this time, the blade 542 fixedly connected to the mounting cylinder 54 rotates to blow air to the printed paper to accelerate the drying of the ink on the paper;

[0041] The folded paper is conveyed by the first conveyor roller 6 and the second conveyor roller 61 for the next step of binding. The second groove 65 on the first conveyor roller 6 and the second conveyor roller 61 corresponds to the first groove 532, so that the crease on the paper will not be flattened by the first conveyor roller 6 and the second conveyor roller 61 when the paper is conveyed by the first conveyor roller 6 and the second conveyor roller 61.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
