[0049] The detailed description and technical contents of the present invention will be described as follows with reference to the accompanying drawings, however, the drawings are only for illustrative purposes and are not intended to limit the present invention.

[0050] Please refer to Figure 1 to Figure 2As shown, the present invention provides a printing device and a continuous paper feeding and cutting device thereof, which are used for a continuous report paper 100, and the continuous report paper 100 is provided with a plurality of holes 101. The printing device 10 mainly includes a printer 1 and a continuous paper feeding and cutting device 2, and the continuous paper feeding and cutting device 2 mainly includes a paper picking module 22, a buffer module 24, a cutting mechanism 26 and a processing unit.

[0051] like Figure 2 As shown, the printer 1 has a paper inlet 11 and a paper feeding mechanism 12 corresponding to the paper inlet 11. The paper feeding mechanism 12 is used to feed paper into the paper inlet 11. The paper feeding mechanism 12 includes a paper feeding wheel (not shown) and a driving gear set (not shown). The driving gear set (not shown) drives the paper feeding wheel (not shown) to rotate. When the paper feeding wheel (not shown) rotates, it can drive the paper to enter the printer 1 from the paper inlet 11. The driving gear set (not shown) includes a linkage gear 121. The printer 1 of this embodiment is a laser printer, but it is not limited to this.

[0052] like Figure 1 to Figure 2 As shown, the continuous feeding and cutting device 2 further includes a portable stage 21. The paper inlet 11 of the printer 1 has a manual paper feed tray 200 that can be opened or closed corresponding to the paper inlet 11. The user first places the portable stage 21 on the manual paper feed tray 200, and then assembles the portable stage 21 at the paper inlet 11 of the printer 1. The portable stage 21 can be detachably connected to the printer 1, that is, the portable stage 21 can be assembled or disassembled from the printer 1, so that the continuous feeding and cutting device 2 can be detachably connected to the printer 1 and configured corresponding to the paper inlet 11.

[0053] like Figure 1 to Figure 2 As shown, the paper picking module 22 is used to convey the continuous report paper 100 to the paper inlet 11. The paper picking module 22 includes a driving wheel 221, a driven wheel 222, and a transmission belt 223 wrapped around the driving wheel 221 and the driven wheel 222 and rotating with the driving wheel 221. The transmission belt 223 has a plurality of convex columns 2231, and the plurality of convex columns 2231 penetrate the plurality of holes 101 of the continuous report paper 100. The transmission belt 223 can be a chain or a belt, but is not limited thereto.

[0054] In addition, the paper picking module 22 further includes a transmission mechanism 224, one end of which is connected to the driving wheel 221 and drives the driving wheel 221 to rotate, and the other end has an electromagnetic clutch 2241, the electromagnetic clutch 2241 includes an active component 2245 and a driven component 2246, the active component 2245 and the driven component 2246 are combined or separated by an electromagnetic mechanical connector (not shown), and the active component 2245 engages with the linkage gear 121 and rotates with the linkage gear 121.

[0055] Further explanation is as follows, the transmission mechanism 224 includes the aforementioned electromagnetic clutch 2241, a driven wheel 2242, a first crawler 2243 and a second crawler 2244, the first crawler 2243 is covered on the outside of the driven component 2246 and the driven wheel 2242 and rotates following the driven component 2246, and the second crawler 2244 is covered on the outside of the driven wheel 2242 and the driving wheel 221 and rotates following the driven wheel 2242. The first crawler 2243 and the second crawler 2244 can be chains or belts, but are not limited thereto.

[0056] Furthermore, when the active component 2245 and the driven component 2246 are engaged, the active component 2245 drives the driven component 2246 to rotate, and the driven component 2246 drives the first crawler 2243 and the driven wheel 2242 to rotate, and the driven wheel 2242 drives the second crawler 2244 and the active wheel 221 to rotate, and finally the active wheel 221 drives the transmission belt 223 and the driven wheel 222 to rotate, and the transmission belt 223 is penetrated by a plurality of holes 101 through a plurality of convex columns 2231, so as to continuously drive the continuous report paper 100 to move toward the paper inlet 11 of the printer 1. Moreover, when the active component 2245 and the driven component 2246 are separated, the active component 2245 does not drive the driven component 2246 to rotate.

[0057] like Figure 1 to Figure 2 As shown, the buffer module 24 is disposed between the paper feed port 11 and the paper pick-up module 22. The buffer module 24 is used to guide the continuous report paper 100 to be moved to the paper feed port 11 in a curved manner. The buffer module 24 includes an arc guide plate 241 and a paper stop member 25. The arc guide plate 241 is disposed between the paper feed port 11 and the paper pick-up module 22. The cross-section of the arc guide plate 241 is a U-shaped sheet, so that the continuous report paper 100 is first bent into a curvature along the arc guide plate 241 and then moved to the paper feed port 11.

[0058] like Figure 1 to Figure 2 As shown, the paper-resisting member 25 is located above the arc-shaped guide plate 241. The paper-resisting member 25 is used to press against the continuous report paper 100. The paper-resisting member 25 includes a fixed seat 251, a pressing roller 252 and a spring 253. The fixed seat 251 is located above the arc-shaped guide plate 241. The pressing roller 252 is located between the arc-shaped guide plate 241 and the fixed seat 251. The spring 253 is elastically supported between the fixed seat 251 and the pressing roller 252 and drives the pressing roller 252 to press against the continuous report paper 100.

[0059] like Figure 1 to Figure 2As shown, the cutting mechanism 26 is disposed between the paper picking module 22 and the buffer module 24. The cutting mechanism 26 is used to cut the continuous report paper 100. The cutting mechanism 26 of this embodiment includes an upper cutter 261 and a lower cutter 262. The upper cutter 261 and the lower cutter 262 are arranged on the upper and lower sides of the continuous report paper 100 and cut the continuous report paper 100 together. However, this is not a limitation. The cutting mechanism 26 may also only include the upper cutter 261, and the continuous report paper 100 is cut from top to bottom by the upper cutter 261.

[0060] like Figure 1 to Figure 2 As shown, the continuous paper feeding and cutting device 2 further includes a paper fixing wheel 23, which is disposed between the buffer module 24 and the cutting mechanism 26. The paper fixing wheel 23 is used to clamp the continuous report paper 100. The detailed description is as follows. The paper fixing wheel 23 includes an upper roller 231 and a lower roller 232 which are arranged on the upper and lower sides of the continuous report paper 100 and jointly support the continuous report paper 100.

[0061] In addition, the processing unit (not shown) is electrically connected to the printer 1, the cutting mechanism 26 and the electromagnetic clutch 2241. The processing unit (not shown) receives the printing information and controls the active component 2245 and the driven component 2246 to combine or separate after calculation, and controls the cutting mechanism 26 to cut the continuous report paper 100.

[0062] The processing unit (not shown) can receive the printing information of the printer 1 through a connector or a wireless connection. The processing unit (not shown) can be installed on the cutting mechanism 26 and the electromagnetic clutch 2241 or remotely connected to control the cutting mechanism 26 and the electromagnetic clutch 2241.

[0063] like Figure 1 to Figure 2 As shown, the continuous paper feeding and cutting device 2 further includes a paper detection sensor 27, which is disposed between the paper fixing wheel 23 and the buffer module 24. The paper detection sensor 27 is used to sense the continuous report paper 100 and generate a paper sensing signal. The processing unit (not shown) receives the paper sensing signal and controls the cutting mechanism 26 to cut the continuous report paper 100 after calculation.

[0064] In addition, the aforementioned paper picking module 22 , paper fixing wheel 23 , arc guide plate 241 , paper stopper 25 , cutting mechanism 26 and paper detection sensor 27 are all accommodated in the portable platform 21 , and the arc guide plate 241 and the fixing seat 251 are extended from the portable platform 21 .

[0065] like Figure 1 to Figure 2As shown, the use state of the printing device 10 and the continuous paper feeding and cutting device 2 of the present invention is that one end of the continuous report paper 100 is passed through the paper fixing wheel 23. After that, when the processing unit (not shown) receives the printing information of the start of printing, the processing unit (not shown) controls the active component 2245 and the driven component 2246 to engage, so that the linkage gear 121 and the active component 2245 drive the driven component 2246 to rotate, so that the paper picking module 22 conveys the continuous report paper 100 to the arc guide plate 241, and the continuous report paper 100 is first bent into a curvature along the shape of the arc guide plate 241 and then moves to the paper inlet 11. Finally, the continuous report paper 100 enters the printer 1 for printing.

[0066] Afterwards, when the paper detection sensor 27 detects the leading edge of the continuous report paper 100 , the printer 1 and the processing unit (not shown) will calculate the required printing length of the continuous report paper 100 according to the printing data.

[0067] When the paper detection sensor 27 detects that the length of the continuous report paper 100 being transported reaches the printing length, or the processing unit (not shown) calculates that the length of the continuous report paper 100 being transported reaches the printing length, the processing unit (not shown) will control the cutting mechanism 26 to cut the continuous report paper 100. At the same time, the processing unit (not shown) will also control the active component 2245 to separate from the driven component 2246, that is, the continuous paper feeding and cutting device 2 will no longer transport the continuous report paper 100. When the continuous paper feeding and cutting device 2 no longer transports the continuous report paper 100, the paper feeding mechanism 12 will still feed the continuous report paper 100 into the paper inlet 11 until the printer 1 finishes printing the print data.

[0068] Among them, Figure 2 As shown, when the continuous paper feeding and cutting device 2 does not feed the continuous report paper 100, but the paper feeding mechanism 12 still feeds the continuous report paper 100 into the paper inlet 11, the paper feeding mechanism 12 will apply a large pulling force to the continuous report paper 100, thereby driving the continuous report paper 100 away from the arc guide plate 241. At the same time, the paper pressing member 25 can provide a buffering force due to the spring 253, so it continues to press the continuous report paper 100 to prevent the continuous report paper 100 from being deflected or pulled, so that the continuous report paper 100 can be cut while being printed without causing paper pulling, thereby eliminating the problem of printing errors or imperfections caused by paper pulling.

[0069] In addition, the continuous report paper 100 passes through the cutting mechanism 26 and enters between the upper roller 231 and the lower roller 232. The upper roller 231 and the lower roller 232 limit the position of the continuous report paper 100 to prevent the continuous report paper 100 from being too thin or too soft and being unable to be cut due to insufficient tension during cutting. The upper cutter 261 and the lower cutter 262 jointly cut the continuous report paper 100 of a predetermined length.

[0070] Therefore, the continuous paper feeding and cutting device 2 of the present invention can be installed on the paper inlet 11 of the printer 1, so that the printer 1 has the functions of printing, paper cutting, and cutting while printing. In addition, the automatic paper cutting action of the continuous paper feeding and cutting device 2 is convenient for the user to take the printed manuscript, and can also prevent too much unprinted blank continuous report paper 100 from being left in the printer 1 and causing machine wear and tear.

[0071] In addition, the paper picking module 22 of this embodiment adopts the electromagnetic clutch 2241 which will engage the linkage gear 121 and follow the rotation of the linkage gear 121 when powered on, which can save the paper picking power of the paper picking module 22 using a stepping motor in the prior art.

[0072] In addition, because the paper-receiving member 25 is elastically supported between the fixing seat 251 and the pressing roller 252 by the spring 253, the pressing roller 252 is driven to press against the continuous report paper 100, so that the printer 1 continues to print and take paper. However, when the paper-taking module 22 stops conveying the continuous report paper 100 and cuts the continuous report paper 100, the horizontal rotation of the pressing roller 252 and the vertical expansion and contraction of the spring 253 can be used as a buffer to prevent the continuous report paper 100 from being pulled, so that the continuous feeding and cutting device 2 has the advantage of being able to stably convey and cut the continuous report paper 100.

[0073] like Figure 3 FIG. 2 is another embodiment of the paper picking module 22 of the present invention. Figure 3 Examples and Figure 1 to Figure 2 The embodiments are roughly the same. Figure 3 Examples and Figure 1 to Figure 2 The difference between the embodiment of the present invention is that the paper picking module 22 further includes a stepping motor 225 connected to and driving the driving wheel 221 to rotate.

[0074] Further explanation is as follows: Figure 1 to Figure 2 In the embodiment, the electromagnetic clutch 2241 is omitted, which engages with the interlocking gear 121 and moves in a rotational manner following the interlocking gear 121 when energized, and instead uses a stepping motor 225 as the paper picking power of the paper picking module 22.

[0075] In addition, the processing unit (not shown) is electrically connected to the stepper motor 225. The processing unit (not shown) controls the rotation speed of the stepper motor 225 when receiving printing information.

[0076] In summary, the printing device and its continuous paper feeding and cutting device of the present invention have never been seen in similar products and have not been publicly used. They are industrially applicable, novel and progressive, and fully meet the requirements for patent applications. Therefore, an application is filed in accordance with the Patent Law to protect the rights of the inventor.
