This disclosure is directed to a continuous feeding and cutting device of a printer, in particular to a printing equipment and a continuous feeding and cutting device thereof.
A dot matrix printer has a set of pins for printing, the pins can accurately hit on a copy paper to print with a copy. Therefore, Dot matrix printers are usually use for printing continuous form papers such as invoices, shipping orders, receipts, and medication orders.
However, the dot-matrix printer is noisy and monochromatic, and has a resolution of about 300 dpi. These makes users feel troubled during operation. Therefore, it is an important issue in the industry that how to print the continuous form paper by a common laser printer in the office when it is printed without a copy.
In views of this, in order to solve the above disadvantage, the inventor studied related technology and provided a reasonable and effective solution in this disclosure.

Moreover, the paper picking module 22 further has a transmission mechanism 224, the transmission mechanism 224 has one end connected with the driving wheel 221 and driving the driving wheel 221 to rotate, and another end having an electromagnetic clutch 2241. The electromagnetic clutch 2241 has a driving part 2245 and a driven part 2246, the driving part 2245 and the driven part 2246 may be connected to or separated from each other by an electromagnetic mechanical connector (not shown in figures). The driving part 2245 is engaged with the linking gear 121 and rotated by the linking gear 121.
Furthermore, as aforementioned paragraph, the transmission mechanism 224 has the electromagnetic clutch 2241, a driven wheel 2242, a first track 2243 and a second track 2244. The first track 2243 hoops the driven part 2246 and the driven wheel 2242 and driven by a rotation of the driven part 2246, the second track 2244 hoops the driven wheel 2242 and the driving wheel 221 and driven by the rotation of the driven wheel 2242. The first track 2243 and the second track 2244 may be chains or straps, but it is not limited to this.
Moreover, when the driving part 2245 and driven part 2246 are engaged with each other, the driving part 2245 drives the driven part 2246 to rotate, the driven part 2246 further drives the first track 2243 to rotate the driven wheel 2242, the driven wheel 2242 further drives the second track 2244 and the driving wheel 221 to rotate, and the driving wheel 221 drives the transmission endless belt 223 and the follower wheel 222 to rotate finally. The transmission endless belt 223 transfer continuously drive the continuous form paper 100 to move toward the inlet 11 of the printer 1 by the plurality of bumps 2231 inserted into the holes 101. Furthermore, when the driving part 2245 is separated from the driven part 2246, the driving part 2245 cannot drive the driven part 2246 to rotate.

According to
Moreover, the processing unit (not shown in figures) is electrically connected to the printer 1, the cutting mechanism 26 and the electromagnetic clutch 2241. The processing unit (not shown in figures) calculates a printing information when receiving that, then correspondingly controls the driving part 2245 to engage or separated from the driven part 2246, and controls the cutting mechanism 26 to cut the continuous form paper 100.
Specifically, the processing unit (not shown in figures) may receive the printing information from the printer 1 via a connecter or a wireless connection, the processing unit (not shown in figures) may be arranged on the cutting mechanism 26 or on the electromagnetic clutch 2241 and may control the cutting mechanism 26 and the electromagnetic clutch 2241 by remote controlling.
According to
Moreover, the paper picking module 22, paper fixing wheel 23, the curved guide 241, the paper presser 25, the cutting mechanism 26 and the paper sensor 27 aforementioned are contained in the portable platform 21, and the curved guide 241 and the fixed seat 251 are extended from the portable platform 21.
According to an operation status of the printing equipment 10 and the continuous feeding and cutting device 2 of this disclosure as shown in
Then, the printer 1 and the processing unit (not shown in figures) calculate a printing length of the continuous form paper 100 according to a requirement of a printed data when the paper sensor 27 detects a leading edge of the continuous form paper 100.
When the paper sensor 27 further detects a length of the continuous form paper 100 is equal to the printing length or a length of the continuous form paper 100 calculated by the processing unit (not shown in figures) calculates is equal to the printing length, the processing unit (not shown in figures) controls the cutting mechanism 26 to cut the continuous form paper 100, and the processing unit (not shown in figures) meanwhile controls the driving part 2245 to separate from the driven part 2246, namely that the continuous feeding and cutting device 2 stop transferring the continuous form paper 100. When the continuous feeding and cutting device 2 stops transferring the continuous form paper 100, the feeding mechanism 12 keeps transferring the continuous form paper 100 into the inlet 11 until the printed data is completely printed by the printer 1.
According to
Additionally, the continuous form paper 100 is transferred between the upper pulley 231 and the lower pulley 232 when passing through the cutting mechanism 26, the continuous form paper 100 is limited at specific position by the upper pulley 231 and the lower pulley 232, so that the continuous form paper 100 is prevented from cutting failure caused by insufficient tension if the continuous form paper 100 is too thin or too soft. The upper cutter 261 is cooperated with the lower cutter 262 to cut the continuous form paper 100 with a predetermined length.
Accordingly, the continuous feeding and cutting device 2 may be additionally disposed on the inlet 11 of the printer 1 to allow the printer 1 to print, cut and print and cut at the same time. Moreover, the continuous feeding and cutting device 2 is capable of cutting automatically, it is convenient for a user to take the printed document, and the printer 1 is also prevented from damaged caused by too many unprinted continuous form papers 100 contained in the printer 1.
Additionally, the paper picking module 22 of this disclosure has the electromagnetic clutch 2241 which is capable of engaging the linking gear 121 and rotated with the linking gear 121 when powered on, so that it is more power efficient compared with the related art which uses a stepper motor for driving the paper picking module 22 to pick paper sheet.
Moreover, the paper presser 25 is disposed between the he fixed seat 251 and the pressing pulley 252 for an elastic supporting by the spring 253, thereby driving the pressing pulley 252 to press the continuous form paper 100 and keep the printer 1 to print and pick paper continuously. However, the moment of cutting the continuous form paper 100 when the paper picking module 22 stops transferring the continuous form paper 100, the continuous form paper 100 may be prevented from pulling via a buffer in the horizontal direction caused by a rotation of the pressing pulley 252 and a buffer in the vertical direction caused by a compression or an extension of the spring 253. Therefore, the continuous feeding and cutting device 2 can stably transfer and cut the continuous form paper 100.
