Description

Technical Field

[0001] This application relates to the field of office equipment automation technology, and in particular to an automatic flipping mechanism for duplex printing in a photocopier. Background Technology

[0002] In the current office equipment market, duplex printing has become a standard feature of mid-to-high-end copiers. With increasing environmental awareness and rising paper costs, duplex printing technology can reduce paper consumption by 50%, significantly lowering business operating costs.

[0003] Currently, in traditional copier flipping mechanisms, the flipping fork is connected to the motor via a coupling, and the motor drives the flipping fork to rotate, which in turn flips the paper. However, the flipping fork cannot hold the paper in place, causing the paper to easily fall off the surface of the flipping fork during the flipping process. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an automatic flipping mechanism for double-sided printing in a photocopier, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: an automatic flipping mechanism for double-sided printing in a copier, comprising a copier, a mounting frame fixedly connected to the surface of the copier, a motor fixedly connected to one side of the mounting frame, a rotating rod fixedly connected to the output end of the motor, a flipping fork fixedly connected to the surface of the rotating rod, an adsorption mechanism provided on the side of the rotating rod away from the motor, the adsorption mechanism comprising an air pump, the air pump fixedly connected to the mounting frame, a connecting pipe fixedly connected to the output end of the air pump, the end of the connecting pipe away from the air pump being rotatably connected to the rotating rod, a connecting groove being provided inside the rotating rod, a through hole being provided on the surface of the flipping fork, the through hole and the connecting groove being connected to the connecting groove, and a conveying mechanism provided on one side of the mounting frame.

[0006] In a preferred embodiment, the conveying mechanism includes a fixed frame, which is fixedly connected to a mounting frame. A fixed rod is rotatably connected inside the fixed frame. A second motor is fixedly connected to one side of the fixed rod, which is fixedly connected to the mounting frame. A pressure roller is fixedly connected to the surface of the fixed rod.

[0007] By adopting the above technical solution, the fixing rod and motor 2 are fixed by the fixing frame, and the output end of motor 2 rotates to drive the fixing rod to rotate. The rotation of the fixing rod then drives the pressure roller to rotate, and the rotation of the pressure roller conveys the paper, which can better convey the paper.

[0008] In a preferred embodiment, a protective pad, which is a rubber component, is fixedly connected to the surface of the pressure roller.

[0009] By adopting the above technical solution, a protective pad is fixedly connected to the surface of the pressure roller, and the protective pad prevents the pressure roller from tearing the paper, thus better preventing the pressure roller from tearing the paper.

[0010] In a preferred embodiment, a filter membrane is fixedly connected inside the through hole.

[0011] By adopting the above technical solution, a filter membrane is fixedly connected inside the through hole, and the filter membrane filters impurities in the air, which can better filter impurities in the air and prevent impurities from entering the interior of the through groove.

[0012] In a preferred embodiment, an infrared beam sensor is fixedly connected to the surface of the mounting bracket, and the infrared beam sensor is electrically connected to the motor.

[0013] By adopting the above technical solution, an infrared photoelectric sensor is fixedly connected to the surface of the mounting bracket, and the infrared photoelectric sensor detects the paper, which can improve the detection of paper.

[0014] In a preferred embodiment, the surface of the mounting bracket is provided with a through groove, which is adapted to the flip fork.

[0015] By adopting the above technical solution, through grooves are opened on the surface of the mounting frame, and the through grooves are adapted to the flip fork, so that the flip fork can rotate better inside the mounting frame.

[0016] In a preferred embodiment, the interior of the mounting bracket is inclined.

[0017] By adopting the above technical solution, and by setting the interior of the mounting frame at an angle, the paper can slide more smoothly inside the mounting frame.

[0018] The beneficial effects of this application are:

[0019] 1. This automatic flipping mechanism for duplex printing in a copier is provided by setting up an air pump, a connecting pipe, a connecting groove, and a through hole. The connecting pipe connects the connecting groove and the air pump, and the through hole delivers air between the paper and the flipping fork to the inside of the connecting groove. The air pump then draws the air from the inside of the connecting groove into the connecting pipe, and the connecting pipe then discharges the air, thus adsorbing the paper onto the surface of the flipping fork. This avoids the problem of paper easily falling off the surface of the flipping fork during the flipping process in traditional copier flipping mechanisms, thus improving practicality.

[0020] 2. This automatic flipping mechanism for duplex printing in a copier is configured with a second motor, a fixed rod, a pressure roller, and a fixed frame. The fixed frame secures the fixed rod and the second motor. The output of the second motor rotates, driving the fixed rod to rotate, which in turn drives the pressure roller to rotate, thus feeding the paper. This avoids the problem of traditional copier flipping mechanisms being unable to feed paper, thereby improving practicality. Attached Figure Description

A pressure roller 43 is fixedly connected to the surface of the fixed rod 42. The fixed rod 42 and the second motor 41 are fixed by the fixed frame 44. The output end of the second motor 41 rotates to drive the fixed rod 42 to rotate. The rotation of the fixed rod 42 drives the pressure roller 43 to rotate. The rotation of the pressure roller 43 then conveys the paper, which can better convey the paper.

[0029] Reference Figure 4 A protective pad, which is a rubber component, is fixedly connected to the surface of the pressure roller 43. The protective pad prevents the pressure roller 43 from tearing the paper, thus better preventing the pressure roller 43 from tearing the paper.

[0030] Reference Figures 1-3 A filter membrane is fixedly connected inside the through hole 34. The filter membrane filters impurities in the air through the through hole 34, which can better filter impurities in the air and prevent impurities from entering the interior of the connecting groove 33.

[0031] Reference Figure 4 An infrared photoelectric sensor 6 is fixedly connected to the surface of the mounting bracket 44. The infrared photoelectric sensor 6 is electrically connected to the motor 2. By fixing the infrared photoelectric sensor 6 to the surface of the mounting bracket 44, the paper can be detected more effectively.

[0032] Reference Figure 2 The surface of the mounting bracket 5 is provided with a through groove, which is adapted to the flip fork 8.

[0033] Reference Figure 2 The interior of the mounting frame 5 is inclined; by inclining the interior of the mounting frame 5, the paper can slide more smoothly inside the mounting frame 5.

[0034] Working principle: Paper is placed inside the mounting frame 5. The fixing rod 42 and motor 41 are fixed by the fixing frame 44. The output end of motor 41 rotates to drive the fixing rod 42 to rotate. The rotation of the fixing rod 42 drives the pressure roller 43 to rotate. The pressure roller 43 then feeds the paper. The connecting pipe 32 connects the connecting groove 33 and the air pump 31. The air between the paper and the flip fork 8 is delivered to the inside of the connecting groove 33 through the through hole 34. The air pump 31 draws the air from the inside of the connecting groove 33 into the connecting pipe 32 and then discharges the air through the connecting pipe 32, adsorbing the paper onto the surface of the flip fork 8. The output end of motor 2 rotates to drive the rotating rod 7 to rotate. The rotating rod 7 then drives the flip fork 8 to rotate. The flip fork 8 then flips the paper. Finally, the air pump 31 is turned off, allowing the paper to slide into the copier 1.
