Description

Technical Field

[0001] The utility model relates to the technical field of inkjet printing equipment, in particular to an inkjet system based on a single-head and double-head small printer. Background Technique

[0002] A photo printer precisely sprays color ink on a special material medium through its nozzles, thereby printing various patterns. The printing process begins with sending the data to be printed through a data transmission interface (such as a USB interface or a network interface) to the main board of the printer. After receiving the data, the main board transmits these data signals to the carriage board through a data cable. The decoder on the carriage board further transmits the data signals to the contact strip, and the contacts on the contact strip perform corresponding energization and de-energization operations according to the instructions of the data signals. These operations work in cooperation with the chips on the nozzles to precisely control the inkjet process and finally form beautiful images. With the continuous growth of people's demand for portability and ease of use, the market demand for small-sized printers is also increasing day by day. Summary of the Invention

[0015] To make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0016] An inkjet system based on a single - dual - head small printer includes a carriage board. The carriage board includes a bottom plate and a control circuit board stacked with functional components integrated thereon and a waveform circuit board for generating a voltage waveform to control the inkjet operation of the nozzle. The control circuit board is connected to the main board through a 26P cable.

[0017] In this embodiment, the carriage board consists of three parts: the bottom plate, the control circuit board, and the waveform circuit board. These three parts are structured in a stacking architecture mode, so the size of the board is greatly reduced. At the same time, the control circuit board is connected to the main board through a 26P cable, eliminating the need for the customer to pull an additional power cable, and greatly reducing the space of the drag chain;

[0018] Among them, the main board controls peripherals such as motors, ink pumps, and fans, and the machine actions and functions are completed by the control circuit board on the carriage board; the grating position signal is input into the carriage board, and after being processed by the carriage board, it forms an inkjet synchronization signal.

[0019] Further, the control circuit board is communicatively connected to an external computer to form a local area network. When starting up, the main board enables the DHCP service to assign an IP to the network port connected to the carriage board.

[0020] The computer and the carriage board are connected using an independently developed big data network transmission protocol. Network packets are used for communication. An independently developed communication protocol and message distribution mechanism are adopted between the carriage board and the main board, enabling efficient, stable, and reliable communication between every two boards.

[0021] Furthermore, an adapter seat is installed on the bottom board of the carriage board, and at most a pair of nozzles are connected to the adapter seat.

[0022] Furthermore, the size of the bottom board of the carriage board is 83MM * 96MM, which can ensure that the head and frame of the customer's machine are smaller, thus ensuring the versatility of the carriage board and enabling it to be more flexibly applied to desktop small machines.

[0023] Furthermore, differential communication mode is adopted for the serial communication interconnection between the main board and the control circuit board, greatly enhancing the anti-interference effect of signal transmission.

[0024] Furthermore, four types of signals, namely VPP power supply, motor drive signal, serial communication, and GND, are transmitted between the main board and the control circuit board through a 26P cable.

[0025] The working process and principle of the present utility model are as follows:

[0026] The computer converts the image data to be printed into print data through RIP software (image processing software), and then transmits the print data to the carriage board through the network cable. The carriage board processes the received print data, calculates position information such as the printing start position by obtaining the magnetic grating signal, and transmits it to the main board. The main board controls the XY-axis movement and auxiliary functions such as paper feeding and discharging. After the carriage moves to the printing position, it controls the nozzles to inkjet. The carriage board controls the nozzle control board to inkjet synchronously by outputting a synchronization signal, thereby achieving the purpose of printing.
