Description

Technical Field

[0001] The invention relates to the technical field of printing equipment, and in particular to a single-guide beam dual-mode adaptive rotary printing equipment. Background Art

[0002] With the advent of the digital age, digital printing technology has been widely welcomed for its ability to provide higher quality and more diverse printing effects. Especially in industries such as advertising, decoration, and textiles, the demand for personalization and customization is growing, which has prompted a continuous pursuit of the performance of printing equipment. Traditional printing equipment is mainly divided into two categories: Multi Pass (multi-pass printing) and Single Pass (one-pass printing).

[0003] Multi Pass: In this mode, the printhead will move back and forth on the material multiple times to complete the printing task. It is suitable for large-format printing projects that require high precision and rich details, because each pass can gradually add color layers to achieve extremely high color saturation and image resolution. However, since the printing vehicle needs to frequently accelerate and decelerate back and forth, the overall printing speed is slow and the production efficiency is low.

[0004] Single Pass: In contrast, the single pass mode arranges all nozzles at once in a form larger than the required printing width, and the material only needs one pass to print the entire screen. This method significantly increases the printing speed and is suitable for mass production and fast delivery requirements. However, its limitations are that the cost of the nozzle array is high, and once the nozzle configuration is determined, it is difficult to adapt to screen requirements of different sizes or complexities.

[0005] Existing solutions on the market often only allow one printing method, which means users must compromise between printing quality and speed. For companies that want to achieve both high efficiency and high-quality output, such limitations are undoubtedly a major challenge. In addition, devices in a single mode cannot flexibly respond to market changes, increasing the operating costs and management difficulties of the company.

[0006] Therefore, a single-guide beam dual-mode adaptive rotary printing device is proposed to solve the above problems. Summary of the invention

[0007] In order to solve the above problems, the present invention provides a single guide beam dual-mode adaptive rotary printing device, which can flexibly switch between Multi Pass and Single Pass according to actual needs to meet the printing requirements of different sizes, widths and precisions, while optimizing production efficiency and cost-effectiveness.

[0009] When the Single Pass (one-pass printing) mode is confirmed, the self-rotating printing vehicle is driven to the designated position through the driving module, and continuous printing is achieved through system software control.

[0010] When the Multi Pass mode is confirmed, the nozzle module is moved 90° clockwise by rotating the motor, and the positioning cylinder assembly pushes the positioning pin to lock the nozzle module to ensure that the nozzle module no longer rotates. Then, through the control of the system software, the drive module drives the second synchronous belt to move to realize printing in the Multi Pass mode.

The second synchronous belt drives the self-rotating printing vehicle to move linearly on the guide rail beam; the tensioning wheel is installed on the motor bracket and adjusts the tightness of the first synchronous belt, and the guide roller adjusts the position of the second synchronous belt.

[0013] Further describing the aforementioned scheme, the nozzle module also includes a nozzle fixing plate, a positioning bracket and a positioning hole. The nozzle is connected to the ink bag and arranged in the center of the nozzle fixing plate. The positioning bracket is arranged at the four corners of the nozzle fixing plate. The positioning hole is arranged in the center of the positioning bracket. A position sensing plate is also installed on the positioning bracket.

[0014] Further describing the aforementioned scheme, the backplane assembly also includes a cooling fan, a supporting bracket, and a board substrate. The supporting bracket is connected to a fixed frame and a guide plate. The guide plate is installed on a slider. The board substrate is vertically connected to the guide plate. The board and the cooling fan are installed on the board substrate and the cooling fan dissipates heat for the board. The board is also wrapped with a cover.

[0044] See also Figure 3 , 4 The guide rail beam 1 includes a guide rail beam bracket 11, a drag chain bracket 12, a guide rail 14, a slider 15, a buffer 16, an ink tube connection groove 13 and a grating 17.

[0045] like Figure 5 As shown, the driving module 3 is installed at one end of the guide rail beam 1, and the driving module 3 includes a servo motor 31, a motor bracket 32, a gear 33, a first synchronous belt 34, a tensioning wheel 35, a synchronous wheel 36, a guide roller 37 and a second synchronous belt 38. The servo motor 31 is installed on the motor bracket 32 ​​and drives the first synchronous belt 34 to rotate through the gear 33.

[0046] In order to have a more thorough and comprehensive understanding of the disclosure of the present invention, the principle thereof is further explained below in conjunction with the usage method.

[0047] When in use, the inkjet carriage is in the default Single Pass (one pass printing) mode, and the self-rotating printing carriage 2 mounted on the guide rail beam 1 is as shown in FIG. Figure 1 As shown, the space for cleaning, moisturizing and wiping the ink structure of the whole nozzle is greatly improved, which provides a lot of space for subsequent maintenance and is convenient for personnel to operate. When working in the Single Pass (one-pass printing) mode, the servo motor 31 of the drive module 3 drives the first synchronous belt 34 and the second synchronous belt 38 to rotate in turn, and then drives the self-rotating printing vehicle 2 to move on the guide rail beam 1. When moving, the grating reader 223 reads the position of the self-rotating printing vehicle 2 on the guide rail beam 1 in real time, and then controls the nozzle module 21 through the system software to realize continuous printing.

[0048] When switching modes, the cylinder 2333 of the positioning cylinder assembly 233 drives the positioning pin 2334 to retract, and the rotating motor 231 drives the transmission shaft 232 to drive the nozzle module 21 to rotate 90 degrees. During the rotation process, the position sensor 2335 monitors in real time. When the positioning hole 215 of the nozzle module 21 reaches the specified position, the cylinder 2333 of the positioning cylinder assembly 233 works again to push out the positioning pin 2334 and just insert it into the positioning hole 215 of the nozzle module 21, so as to effectively fix the nozzle module 21. Figure 6 After the positioning cylinder assembly 233 pushes the positioning pin 2334 to lock the nozzle module 21, the driving module 3 drives the nozzle module 21 to move through the control of the system software, thereby realizing the printing in the Multi Pass mode.
