Description

Technical Field

[0001] The invention relates to the technical field of printer equipment, in particular to an anti-paper jam printer. 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. There are many types of printers. According to whether the printing element hits the paper, they are divided into impact printers and non-impact printers. According to the structure of printed characters, they are divided into full-width character printers and dot-matrix character printers. According to the way a line of characters is formed on paper, they are divided into serial printers and line printers. According to the technology used, they are divided into cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, light-emitting diode and other printers. Inkjet printers The basic working principle of the machine is to first generate small ink droplets, and then use the inkjet head to guide the tiny ink droplets to the set position. The smaller the ink droplets, the clearer the printed image. The basic principle seems simple, but the operation is not that simple. The installation of the printer is generally divided into two parts. One is the connection between the printer and the computer, and the other is to install the printer driver in the operating system. If it is a printer with a USB interface, when installing it, without turning off the computer host and the printer, directly connect one end of the printer's USB cable to the printer and the other end to the USB port of the computer.

[0003] For example, a patent document with a publication number of CN 113978142 B discloses an anti-paper jam printer, including a printer body and a paper pickup shaft rotatably connected to the printer body, a plurality of paper pickup wheels are arranged on the paper pickup shaft, a plurality of paper feed wheels are arranged below the paper pickup wheels, paper passes between the paper pickup wheels and the paper feed wheels, a photoelectric sensor for detecting paper jams is arranged in the printer body, the photoelectric sensor is electrically connected to a PLC, a lifting mechanism, a shearing mechanism, and a cleaning mechanism are arranged in the printer body in sequence along the paper output direction, the shearing mechanism includes a paper cutter, the cleaning mechanism includes a cleaning member for cleaning the paper pickup wheel, and the lifting mechanism is used to simultaneously drive the cleaning member and the paper cutter to vertically lift and lower; after the printer has been used for a period of time, paper jams are likely to occur, and the paper jam may be caused by a lot of dust adhering to the paper pickup wheel, which reduces the friction of the paper pickup wheel and causes paper jams in the printer; the lifting mechanism drives the shearing mechanism and the cleaning mechanism to descend, and while the shearing mechanism cuts the paper, the cleaning mechanism cleans the paper pickup wheel.

[0004] However, during the actual use of the printer, due to the limitation of its own structure, this structure can only push and load the paper inside the printer through the paper rubbing device inside the device. However, the paper itself often lacks the force to keep moving forward inside the printer. Once the paper rubbing device inside the printer is worn out after long-term use, some of the paper will lose power inside the printer during printing, and eventually paper jams will occur inside the printer. The paper rubbing device needs to be disassembled, assembled, maintained and used, which can easily affect the operating efficiency of the printer and make it impossible to achieve continuous, stable and efficient printing of paper. At the same time, the device cannot efficiently load and unload the paper during printer operation, as well as the internal equipment heat dissipation auxiliary operation, and cannot meet daily needs. Therefore, it is urgent to design an anti-paper jam printer to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide an anti-paper jam printer to solve the problem that the existing structure proposed in the above background technology can only push and load the paper inside the printer through the paper rubbing device inside the device due to the limitation of its own structure during the actual use of the printer. However, the paper itself often lacks the applied force inside the printer to make it move forward continuously. Once the paper rubbing device inside the printer is worn out after long-term use, part of the paper will lose power inside the printer during printing, and eventually paper jams will occur inside the printer. The paper rubbing device needs to be disassembled, assembled, maintained and used, which can easily affect the operating efficiency of the printer and cannot achieve continuous, stable and efficient printing of paper.

[0015] Preferably, the printer body, the feed rack and the feed guide frame are connected through a guide plate rack, a conical guide rack and an arc guide rack.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The anti-paper jam printer, through the printer body, feed rack, feed guide frame, discharging rack, discharging guide rack, guide plate rack, conical guide rack, arc guide rack, control rack, control panel, control knob, arc outer rack, arc inner rack, pressed outer air cushion, pressed inner groove, first drive motor, pressing roller, oblique conveying guide rack, oblique conveying guide groove, air control pump, top pressure air bag, conveying frame, fixed conveying roller, movable conveying roller, oblique conveying guide plate, gear set, second drive motor, discharging pressure roller, clamping air bag, clamping roller and limiting side rail, can enable the device to load and unload paper by its own force when the printer is continuously running. Operation, to avoid paper jams, in actual use, the staff first stacks the paper to be printed and places it on the front of the feed rack at the top of the printer body, and then the bottom paper can be inserted into the feed rack by gravity, and follow the feed guide frame to the inside of the guide plate rack. The guide plate rack can start the air pump at one end to inflate the top pressure airbag for up and down transportation, so that the movable conveying rollers and fixed conveying rollers inside the upper and lower conveying frames of the guide plate rack are adaptively positioned and top-connected for transportation, and then follow the top of the conical guide rack into the inside of the arc guide rack. The conical guide frame can also start the first driving motor at one end to drive the internal pressing roller to rotate, and the pressing inner groove of the arc inner frame cooperates with the inclined conveying guide groove of the upper and lower inclined conveying guide frames to perform a fast feeding operation of the printing paper. The arc guide frame can perform arc-shaped adaptation and pressing of the paper through its own arc-shaped structure and the pressing outer air cushion inside the arc outer frame, and bend the printing paper into an arc shape, so that the paper itself carries the stretching force to restore upward and downward, and then the paper passes through the guide plate frame along the bottom end of the conical guide frame and enters the interior of the printer body. At this time, the paper inside the printer body will always carry the arc. The downward stretching force of the arc-shaped bending recovery at the guide rack allows the paper to be quickly and continuously moved and printed inside the printer body without the need for strong pressure from the paper rubbing device, thus avoiding paper jams. At the same time, the printing paper entering the feed rack can be pushed by the compression airbag to push the compression roller at one end, and perform a stable pressure-limiting operation downward along the limiting side rail. When the printing paper is discharged from the discharge rack, the gear set and the second drive motor can be started to drive the stable limiting roller pressure at the upper and lower discharge pressure rollers inside the discharge rack and the discharge guide rack, thereby ensuring that the printing paper can complete the printing operation more stably, reflecting the practicality of the equipment design.

[0017] The anti-paper jam printer further improves the overall use effect of the equipment by arranging a printer body, a first side frame, a second side frame, a heat dissipation fan, a dustproof ring net, a flip frame, a plug-in buckle, a positioning side plate, a first protective pad, a movable shaft, a ventilation grille, a magnetic seal, a ventilation frame, a heat dissipation plate, an air guide frame, an inclined feed guide plate, a loading chute, a positioning side strip and a second protective pad. In daily use, the staff can place the printing paper at the loading chute on the top of the printer body, and then the positioning side strips on both sides of the loading chute and the second protective pad in the center can feed the stacked printing paper into the feed frame one by one, and when the printed paper is output from the inside of the output frame, the inclined feed guide plate at one end of the output frame can feed the printing paper in an oblique upward direction, and then the printing paper falls onto the first protective pad on the surface of the flip frame, and the positioning side plates on both sides of the flip frame stabilize the printing paper. Limiting, when the equipment is not in use, the flip frame can be rotated along the movable axis as a whole, and then the plug-in buckle at one end of the flip frame is buckled on the front of the printer body to perform a shielding and protection operation on the printer body. At the same time, when the printer body is running continuously with high intensity, the cooling fans at one end of the first side frame and the second side frame away from each other can be started synchronously, so that they can cooperate with the ventilation grilles on the side to perform efficient circular flow operation of cooling airflow. At this time, the ventilation frame and the heat sink plate between the first side frame and the second side frame can, with the assistance of the air guide frame, perform a rapid flow operation of the cooling airflow around the printer body, providing it with a more stable heat dissipation operation. The dustproof ring net is mounted on the outer surface of the cooling fan to remove dust from the cooling airflow, and the dustproof ring net can be quickly disassembled and assembled, cleaned and maintained from the side of the cooling fan through a magnetic seal, reflecting the comprehensiveness of the equipment design.

[0023] Working principle: When in use, the user first stacks the paper to be printed and places it on the front of the feed rack 2 at the top of the printer body 1. Then the bottom paper can be inserted into the feed rack 2 by gravity, and come to the inside of the guide plate rack 11 along the feed guide frame 3.
