Description

Technical Field

[0001] The invention belongs to the technical field of printers, and in particular is a combined label printing all-in-one machine for file classification. Background Art

[0002] A printer is one of the output devices of a computer, used to print the results of computer processing on relevant media. There are three indicators to measure the quality of a printer: print resolution, print speed and noise. The types of printers are divided into impact printers and non-impact printers according to whether the printing element has an impact action on the paper; they are divided into full-width character printers and dot matrix character printers according to the structure of printed characters; they are divided into string printers and line printers according to the way a line of characters is formed on paper; they are divided into cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, light-emitting diode and other printers according to the technology used. The combined label printing all-in-one machine is designed for archive management, integrating label printing and classification functions. It is suitable for archives, libraries, large enterprises and other places that need to efficiently manage a large number of archives.

[0003] After searching, the patent with announcement number CN111516400B discloses a combined printer shaft that is easy to install. By opening the fixed block on one side of the print scroll, the print scroll is moved out from the inside of the print fixed bracket by pulling the inkjet bottom cover. When the print scroll male head and the print scroll female head at both ends of the print connection scroll are not fixed, the first docking spring and the second docking spring are moved to replace the adjacent print connection scroll. The roller on one side of the paper storage slot can be moved up and down to replace the new print connection scroll, the anti-slip sleeve and the anti-slip layer, the anti-slip sleeve and the anti-slip layer, so that the print paper is not easily moved out of the bottom of the inkjet box above the print inkjet substrate. The rolling wheel on the top of the print inkjet substrate can make the print paper flat when printing on the print inkjet substrate, which is convenient for the inkjet box to print.

[0004] However, when the combined printer shaft is used, since the thickness of the printing paper is generally 0.1 mm, it is easy for multiple sheets of printing paper to be fed into the printer at the same time or the printing paper to tilt when feeding the printing paper, causing the printer to jam and still being inconvenient to use.

DETAILED DESCRIPTION

[0015] 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.

[0016] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Example

[0017] See also Figure 1-Figure 11The present invention provides a technical solution: a combined label printing all-in-one machine for archive classification, comprising a printer housing 1, and a control box 2 installed on the outer wall of the printer housing 1, a support plate 3 is slidably connected to the inner wall of the printer housing 1, a feed roller 4 is rotatably connected to the inner wall of the printer housing 1, a rubber roller 5 is rotatably connected to the inner wall of the printer housing 1, a guide roller 7 is rotatably connected to the inner wall of the printer housing 1, a conveying member 9 is installed on the inner wall of the printer housing 1, a printer group 10 is installed on the inner wall of the printer housing 1, a guide plate 6 adapted to the feed roller 4 is arranged on the inner wall of the printer housing 1, a scraper 8 adapted to the rubber roller 5 is arranged on the inner wall of the printer housing 1, a feed assembly for conveying printing paper is arranged on the outer wall of the feed roller 4, and an auxiliary feed assembly for driving the support plate 3 to shrink is arranged on the inner wall of the printer housing 1.

[0018] Before use, place the printing paper on the surface of the support plate 3 inside the paper storage slot. During operation, the control box 2 drives the unloading roller 4 to rotate. When rotating, the unloading roller 4 will drive the unloading component to press the surface of the printing paper and adsorb it. Then the unloading roller 4 continues to rotate, driving the auxiliary unloading component to work, so that the auxiliary unloading component pushes the support plate 3 to move 0.1 mm toward the inside of the printer housing 1, thereby releasing the support for the outermost printing paper. At the same time, the unloading roller 4 drives the unloading component to work and feed the printing paper. At this time, the printing paper can be separated from the surface of the unloading roller 4 by the guide plate 6, so that the bottom end of the printing paper is pushed to the surface of the rubber roller 5. Since the rubber roller 5 is sticky, it can adhere to the printing paper. Then, the rubber roller 5 is driven to rotate by the control box 2, and the scraper 8 is cooperated to separate the printing paper from the rubber roller 5, so that the guide roller 7 conveys the printing paper to the surface of the conveying member 9, and finally the printing is performed through the printer group 10.

[0019] See also Figure 3 The unloading assembly includes a groove 11 opened on the outer wall of the unloading roller 4, a connecting shaft 12 is fixedly connected to the inner wall of the groove 11, a unloading block 13 is rotatably connected to the outer wall of the connecting shaft 12, and a torsion spring 14 adapted to the unloading block 13 is arranged on the outer wall of the connecting shaft 12.

[0020] When in use, when the feed roller 4 drives the feed block 13 to move to the surface of the printing paper, the reaction force of the printing paper on the feed block 13 pushes the feed block 13 to rotate around the connecting shaft 12 and applies torque to the torsion spring 14, so that the feed block 13 rotates into the interior of the groove 11. When the feed block 13 completely enters the interior of the groove 11, the arc surface of the feed block 13 that fits the printing paper is on the same horizontal line as the arc surface of the feed roller 4, thereby preventing wrinkles from occurring on the surface of the printing paper when the printing paper is fed, and preventing the feed block 13 from touching the surface of the rubber roller 5 during operation and affecting its normal operation.

[0021] See also Figure 3and Fig. 9 The blanking assembly also includes an empty chamber 15 arranged on the inner wall of the blanking block 13, a first connecting spring 16 is fixedly connected to the inner wall of the empty chamber 15, a piston 17 adapted to the empty chamber 15 is arranged on the outer wall of one end of the first connecting spring 16, a pull rope 18 adapted to the piston 17 is arranged on the outer wall of the groove 11, a connecting channel 19 adapted to the empty chamber 15 is arranged on the inner wall of the blanking block 13, a connecting groove 20 adapted to the connecting channel 19 is arranged on the outer wall of the blanking block 13, a first limit spring 21 is fixedly connected to the inner wall of the connecting groove 20, a first baffle 22 is fixedly connected to the outer wall of one end of the first limit spring 21, a first notch 23 is arranged on the outer periphery of the first baffle 22 along the circumferential direction, and a contact 24 adapted to the connecting groove 20 is arranged on the outer wall of the first baffle 22.

[0022] When the feeding block 13 moves to the surface of the printing paper, the printing paper exerts a reaction force on the feeding block 13 so that the printing paper applies pressure to the surface of the contact 24 and pushes the contact 24 to slide into the inside of the connecting groove 20. When the contact 24 moves, it pushes the first baffle 22 to move synchronously and squeeze the first limit spring 21, thereby releasing the limit on the first notch 23. Then the feeding roller 4 continues to rotate, causing the feeding block 13 to rotate synchronously. At this time, the pull rope 18 pulls the piston 17 to slide downward inside the empty chamber 15 and squeeze the first limit spring 21. A connecting spring 16 allows the empty chamber 15 to suck air into the connecting slot 20 through the connecting channel 19, so that the air outside the group of connecting slots 20 in contact with the printing paper passes through the first notch 23 and enters the interior of the empty chamber 15, thereby adsorbing the printing paper on the surface of the blanking block 13. When the printing paper presses the next group of contacts 24, the connecting slots 20 that adsorb the printing paper will be synchronously converted to the next group, and the original contacts 24 will be reset under the action of the first limit spring 21 and limit the first notch 23.

[0023] See also Fig. 9 The blanking assembly also includes an exhaust port 46 opened on the inner wall of the blanking block 13 and adapted to the connecting channel 19, a second limit spring 47 is fixedly connected to the inner wall of the exhaust port 46, a second baffle 48 is fixedly connected to the outer wall of one end of the second limit spring 47, and a second notch 49 is arranged on the outer periphery of the second baffle 48 along the circumferential direction.

[0024] When the printing paper is unloaded, the force of the torsion spring 14 pushes the unloading block 13 to reset. At this time, the pull rope 18 will release the tension on the piston 17, and the force of the first connecting spring 16 will push the piston 17 to reset and squeeze the air inside the empty chamber 15. After being squeezed, the air inside the empty chamber 15 will enter the exhaust port 46 through the connecting channel 19 and apply a thrust to the surface of the second baffle 48, thereby pushing the second baffle 48 to slide inside the exhaust port 46 and squeeze the second limit spring 47, so as to release the limit on the second notch 49, so that the air entering the exhaust port 46 can pass through the second notch 49 and be discharged to the outside of the unloading block 13.

[0025] See also Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig.10 The auxiliary unloading assembly includes a connecting block 25 mounted on the outer wall of one end of the unloading roller 4, and a connecting column 26 mounted on the inner wall of the printer housing 1. A rotating block 27 is rotatably connected to the outer wall of one end of the connecting column 26. A ratchet 28 is rotatably connected to the outer wall of the connecting column 26. The connecting column 26 is provided with a spring sheet 29 adapted to the ratchet 28. A tooth groove 30 adapted to the ratchet 28 is provided on the inner wall of the rotating block 27 along the circumferential direction. A transmission ring 31 is rotatably connected to the outer wall of the rotating block 27. The inner wall of the rotating block 27 is fixedly connected to There is a return spring 32, and a limit block 33 is fixedly connected to the outer wall of one end of the return spring 32. A push plate 34 adapted to the limit block 33 is arranged on the inner wall of the transmission ring 31, and a transmission belt 35 adapted to the connecting block 25 is arranged on the outer wall of the transmission ring 31. A steel wire strip 36 adapted to the rotating block 27 is arranged on the inner wall of the printer housing 1. A connecting rod 37 is snap-connected to the inner wall of one end of the connecting column 26, and a gear 38 is fixedly connected to the outer wall of the connecting rod 37. A rack 44 adapted to the gear 38 is arranged on the outer wall of the support plate 3.

[0026] When the unloading roller 4 rotates, it will drive the connecting block 25 to rotate synchronously, thereby driving the transmission ring 31 to rotate synchronously through the transmission belt 35, and then driving the push plate 34 to rotate on the surface of the rotating block 27. When the push plate 34 moves to contact with the limit block 33, as the transmission ring 31 continues to rotate, the push plate 34 will apply a thrust to the surface of the limit block 33, thereby pushing the rotating block 27 to rotate. When the rotating block 27 rotates, it will apply a torsional force to the steel wire 36. At the same time, through the engagement of the tooth groove 30 on the surface of the rotating block 27 and the pawl 28, the rotating block 27 will drive the connecting column 26 to rotate synchronously when it rotates. At this time, through the engagement between the connecting column 26 and the connecting rod 37, the connecting column 26 drives the connecting rod 37 to rotate synchronously when it rotates, thereby pushing the gear 38 to rotate. The engagement between the gear 38 and the rack 44 can push the support plate 3 to slide toward the inside of the printer housing 1. The reaction force applied by the steel wire strip 36 on the surface of the rotating block 27 will limit the rotating block 27, so that the thrust applied by the push plate 34 on the surface of the limit block 33 is converted into downward pressure, thereby pushing the limit block 33 to slide toward the inside of the rotating block 27 and squeezing the return spring 32, so that the limit block 33 releases the limit on the push plate 34. After the push plate 34 passes through the surface of the limit block 33, the return spring 32 is forced to push the limit block 33 to return to its original position. At this time, the steel wire strip 36 is forced to push the rotating block 27 to return to its original position. During the resetting process of the rotating block 27, the ratchet 28 is pushed by the tooth groove 30 to rotate on the surface of the connecting column 26 and squeeze the spring sheet 29. After the resetting of the rotating block 27 is completed, the spring sheet 29 is forced to push the ratchet 28 to re-engage with the tooth groove 30, so as to return to the original position, so that the feed roller 4 can push the support plate 3 to slide 0.1 mm toward the inside of the printer housing 1 every time it rotates one circle.

[0027] See also Figure 1 , Figure 5 , Figure 6 and Fig.11 The auxiliary unloading assembly also includes a limiting rod 39 arranged on the inner wall of the connecting rod 37, a connecting plate 40 is fixedly connected to the outer wall of one end of the limiting rod 39, a clamping block 41 is arranged on the outer periphery of the connecting plate 40 along the circumferential direction, a second connecting spring 42 adapted to the connecting plate 40 is arranged on the inner wall of the connecting rod 37, a clamping groove 43 adapted to the clamping block 41 is arranged on the outer wall of the connecting column 26, and a knob 45 is fixedly connected to the outer wall of one end of the limiting rod 39.

[0028] When it is necessary to reset the support plate 3 that has entered the interior of the printer housing 1, the knob 45 is pulled to drive the limit rod 39 to be pulled outward from the interior of the connecting rod 37. When the connecting rod 37 is pulled, the connecting plate 40 is driven to slide inside the connecting rod 37 and stretch the second connecting spring 42. When the connecting plate 40 slides, it drives the block 41 to slide out of the slot 43, thereby releasing the engagement between the connecting rod 37 and the connecting column 26. At this time, the knob 45 is turned to drive the connecting rod 37 and the gear 38 to rotate through the limit rod 39, and the engagement between the gear 38 and the rack 44 can push the support plate 3 to slide out of the interior of the printer housing 1.
