Description

Technical Field

[0001] The present application relates to the technical field of inkjet printers, and in particular to a loading and positioning inkjet printer. Background Art

[0002] An inkjet printer is a common printing device that uses inkjet technology to spray ink onto paper to form text, images, or other content. Inkjet printers usually have high print quality and color expression, and are suitable for printing photos, documents, and other types of printed materials.

[0003] Inkjet printers usually use sensors and control systems to position the printhead to ensure that the printhead prints in the correct position. During the printing process, the printer controls the movement of the printhead according to preset parameters and instructions to ensure that the printed content is accurately placed on the paper. For the paper transmission in the inkjet printer, a stepper motor is used to push the paper to cooperate with the printhead to complete the printing process. In this process, the fixed space reserved by the traditional stepper motor roller structure transmission is used to transmit the paper, and its fit is not good enough, so the inkjet printer is highly dependent on sensors, which increases its computing cost. In this regard, a loading positioning inkjet printer is proposed to solve the above-mentioned problems. Utility Model Content

[0009] Furthermore, the extension member includes a mounting shaft rotatably mounted on the surface of the right-angle frame on one side of the frame and an extension transmission roller fixedly connected to the mounting shaft.

[0010] Furthermore, a pulley for pulling the extension transmission roller to rotate is fixedly connected to one end of the extension transmission roller away from the installation shaft, and a pulley is also fixedly connected to the other end of the power roller away from the stepper motor, and a transmission belt is wound between the two pulleys.

[0011] Furthermore, the mounting frame is an inverted U-shaped frame, a moving frame is slidably mounted on the inner side of the mounting frame, and the pressure roller is rotatably mounted on the inner side of the moving frame.

[0012] Furthermore, a guide groove is provided on the inner side wall of the mounting frame, and the movable frame is fitted in the guide groove.

[0013] Furthermore, a guide rod is fixedly mounted on the top of the movable frame, and the guide rod penetrates and is slidably connected to the mounting frame.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] See also Figure 1-3 In this embodiment, a loading and positioning inkjet printer includes a frame 1 for guiding a nozzle and a transmission component located outside the frame 1, wherein an ink cartridge is connected to the frame 1 through a driving device for inkjet printing on paper passing through the frame 1, and the transmission component includes a power component located on one side of the frame 1 and an extension component located on the other side of the frame 1.

[0023] In this embodiment, the power component includes a stepper motor 4 fixed on the outside of the frame 1 and a power roller 5 fixedly connected to the power end of the stepper motor 4. The surface of the power roller 5 is provided with recessed strips at intervals, so that the transmission contact of the power roller 5 is better.

[0024] It should be noted that a reinforcing plate 2 is fixedly installed on the outside of the frame 1, and both ends of the reinforcing plate 2 are fixedly connected to right-angle brackets 3 fixed on the inkjet printer casing, and the stepper motor 4 is fixed on one right-angle side of the right-angle bracket 3 for fixing.

[0025] In this embodiment, the extension member includes a mounting shaft 6 rotatably mounted on the surface of the right-angle frame 3 on one side of the frame 1 and an extension transmission roller 7 fixedly connected to the mounting shaft 6 .

[0026] Preferably, a pulley 8 for pulling the extension transmission roller 7 to rotate is fixedly connected to one end of the extension transmission roller 7 away from the installation shaft 6, and a pulley 8 is also fixedly connected to the other end of the power roller 5 away from the stepper motor 4, and a transmission belt 9 is wound between the two pulleys 8.

[0027] In a specific implementation, the stepper motor 4 drives the power roller 5 to rotate and transmit the paper, and drives the extended transmission roller 7 on the other side of the frame 1 to rotate through the transmission belt 9, so that the extended transmission roller 7 can assist in paper transmission.

[0028] In this embodiment, a bonding mechanism for strengthening the contact between the paper and the power roller 5 is provided on one end of the frame 1 facing above the power roller 5. The bonding mechanism includes a mounting frame 10 fixedly mounted on the side of the frame 1, a pressure roller 14 located on the inner side of the mounting frame 10, and a transmission member connecting the pressure roller 14 and the power roller 5.

[0029] It should be noted that the mounting frame 10 is an inverted U-shaped frame, a moving frame 11 is slidably mounted inside the mounting frame 10 , and the pressure roller 14 is rotatably mounted inside the moving frame 11 .

[0030] The movable frame 11 slides relative to the mounting frame 10 , so that the position of the pressing roller 14 relative to the mounting frame 10 can be flexibly adjusted.

[0031] Preferably, a guide groove 18 is further provided on the inner wall of the mounting frame 10, and the movable frame 11 fits in the guide groove 18. The movement of the movable frame 11 relative to the mounting frame 10 is further restricted by the restriction of the guide groove 18, thereby improving the movement stability of the movable frame 11.

A connecting tube 16 is integrally extended from one end of the two universal joints 15. A connecting pin 17 is slidably installed between the two connecting tubes 16. The two universal joints 15 are used for transmission connection, so that when the power roller 5 rotates, it can drive the other pressure roller 14 to rotate synchronously, and when the position of the pressure roller 14 changes, transmission can also be performed.

[0035] It should be noted that the connecting pin 17 adopts a plum blossom shaft, so that the rotation of the connecting pin 17 relative to the connecting pipe 16 is limited, thereby improving transmission stability.

[0036] The working principle of the above embodiment is:

[0037] By controlling the stepper motor 4 to work, the stepper motor 4 drives the power roller 5 to rotate, so that the power roller 5 can transmit the paper passing through the power roller 5 while rotating, and at the same time, through the mutual transmission cooperation between the pulley 8 and the transmission belt 9, the extended transmission roller 7 located on the other side of the frame 1 rotates synchronously to transmit the paper, and at the same time, pushed by the spring force of the push spring 12, the moving frame 11 is pushed away from the mounting frame 10, and the pressure roller 14 connected to the moving frame 11 cooperates with the power roller 5 to transmit the paper tightly, and at the same time, under the transmission of the universal joint 15 on one side, the pressure roller 14 rotates synchronously with the power roller 5 to transmit the paper, thereby improving the positioning accuracy.
