Description

Technical Field

[0001] The utility model belongs to the technical field of production equipment, and specifically relates to an inkjet printer. Background Art

[0002] Inkjet printers are widely used in industrial production. Marking intermediate products with inkjet printers is helpful for product identification, tracking and recording product quality, and preventing counterfeiting.

[0003] In the manufacturing process of paper cups, it is often necessary to inkjet code the base paper for making paper cups before proceeding to the next step. The nozzle of the existing inkjet printer is usually located at the bottom of the base paper, and ink is sprayed on the base paper from bottom to top. Such a setting can easily cause the nozzle to be blocked, which has an adverse effect on subsequent production.

[0004] During the transmission process, the base paper is easily offset due to its long path and changing direction, thus affecting the quality of the final product. Utility Model Content

[0005] The utility model aims to solve the problem that the nozzle of the inkjet printer described in the above background technology is easily clogged. A new inkjet printer is proposed. The nozzle of the inkjet printer is horizontally arranged to perform side spraying on the base paper, which is not easy to be clogged.

[0006] A technical solution adopted to achieve the above-mentioned purpose is a printer, the printer comprising:

[0007] A feeding bracket, wherein a rotating shaft is provided at the end of the feeding bracket;

[0008] A feeding mechanism, the feeding mechanism comprising a limiting roller, two guide rollers, a transmission roller and a first motor, the output end of the first motor is provided with a driving gear, the end of the transmission roller is provided with a passive gear, and the driving gear and the passive gear are meshed;

[0009] A frame, the frame comprising a bottom plate, a first mounting plate connected to the top of the bottom plate, a second mounting plate connected to the top of the bottom plate, a support column connected to the top of the second mounting plate, a fixing plate connected to the top of the second mounting plate, and a transmission plate connected to the top of the support column, wherein the fixing plate is provided with a through hole;

[0010] A material receiving mechanism, the material receiving mechanism comprising a second motor and a material receiving roller, wherein an output end of the second motor is connected to the material receiving roller;

[0011] The coding mechanism comprises a nozzle, a conduit and an ink cartridge. The nozzle is connected to the ink cartridge through the conduit, and the nozzle passes through a through hole.

[0012] In the above technical solution, the base paper is wound on the rotating shaft, and the base paper passes through the limit roller, two guide rollers, the transmission roller, two limit mechanisms, the transmission plate and the receiving roller in sequence, wherein the base paper is transmitted from bottom to top through the gap between the two limit rods, the nozzle is perpendicular to the base paper, and the nozzle realizes side spraying to mark the base paper, thereby solving the problem of nozzle blockage.

[0013] Furthermore, the frame also includes two limiting mechanisms, which include two limiting rods and two limiting blocks. The two limiting rods are in the same horizontal plane and are arranged at intervals. One end of the two limiting rods is fixedly connected to the first mounting plate, and the other end of the two limiting rods passes through the two limiting blocks.

[0014] Furthermore, one of the limiting mechanisms is directly below the other limiting mechanism.

[0015] In the above technical solution, the base paper can pass through between the two limit rods, ensuring that the base paper moves vertically from bottom to top between the two limit mechanisms, so that the nozzle can directly face the base paper to achieve coding.

[0016] Furthermore, the limiting roller is provided with two limiting rings.

[0017] In the above technical solution, the limiting ring can guide the bottom paper to be transported and prevent it from deflecting.

[0018] Furthermore, one end of the transmission plate is connected to a downwardly bent arc plate.

[0019] In the above technical solution, the arc-shaped plate can protect the bottom paper from being cut by the edge of the plate when the bottom paper moves onto the transmission plate.

[0020] Furthermore, the peripheral side of the receiving roller is tangent to one end of the transmission plate.

[0021] In the above technical solution, the bottom paper can just contact with the receiving roller, so that the receiving roller pulls the bottom paper.

[0022] Furthermore, the plane to which the nozzle belongs is parallel to the plane to which the bottom plate belongs.

[0023] In the above technical solution, the nozzle is guaranteed to spray sideways and is located below the transmission plate, thus saving space.

[0024] Furthermore, a plurality of limit plates are provided on the transmission plate.

[0025] In the above technical solution, the bottom paper is located below the limiting plate to ensure that the bottom paper is transmitted in a straight line to prevent deviation.

[0026] Furthermore, the inkjet printer also includes a control mechanism, which includes a console and a controller, and the controller is electrically connected to the first motor and the second motor.

[0027] Furthermore, the interior of the console is hollow, the ink cartridge is placed inside the console, and the conduit passes through a side wall of the console.

[0028] The advantages of the utility model are:

[0029] 1. The utility model adjusts the direction of the nozzle to horizontal side spraying to prevent nozzle blockage.

[0030] 2. The utility model is provided with a plurality of limit plates, limit blocks and limit rings to prevent the bottom paper from shifting. BRIEF DESCRIPTION OF THE DRAWINGS
