Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a single-guide beam dual-mode self-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. Utility Model Content

[0007] In order to solve the above problems, the utility model 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 needs of different sizes, widths and precisions, while optimizing production efficiency and cost-effectiveness.

[0008] The utility model discloses a single guide rail beam dual-mode adaptive rotary inkjet printing device, which includes a guide rail beam, a self-rotating printing vehicle, and a driving module. The self-rotating printing vehicle is installed on the guide rail of the guide rail beam and reciprocates on the guide rail beam through the driving module. The self-rotating printing vehicle includes a nozzle module, a backplane assembly, and a fixed frame. The backplane assembly is fixedly connected to the fixed frame. A board card for driving the nozzle is arranged on the backplane assembly. A rotary motor for driving the rotation of the nozzle module and a positioning cylinder assembly for positioning the nozzle module are arranged on the fixed frame. A plurality of nozzles and ink cartridges are integrated on the nozzle module.

[0009] When it is confirmed to perform inkjet printing in the Single Pass (one-pass printing) mode, the driving module drives the self-rotating printing vehicle to a specified position, and continuous inkjet printing is realized through the control of the system software.

[0010] When it is confirmed to perform inkjet printing in the Multi Pass (multi-pass printing) mode, the nozzle module is rotated clockwise by 90° through the rotary 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 driving module drives the second synchronous belt to move to realize inkjet printing in the Multi Pass mode.

[0011] For further description of the foregoing solution, the guide rail beam includes a guide rail beam bracket, a drag chain bracket, a guide rail, a slider, a buffer, and a grating. The guide rail beam bracket is used to fixedly install the guide rail beam on the inkjet printing device. The drag chain bracket is used to support the drag chain. The slider is slidably installed on the guide rail and bears the self-rotating printing vehicle. The buffer is installed at both ends of the guide rail beam to buffer the self-rotating printing vehicle. The grating is installed parallel to the guide rail beam, and a corresponding grating reading head is arranged on the self-rotating printing vehicle to ensure that the self-rotating printing vehicle accurately moves to the desired position.

[0012] For further description of the foregoing solution, the driving module is installed at one end of the guide rail beam. The driving module includes a servo motor, a motor bracket, a gear, a first synchronous belt, a tensioning wheel, a synchronous wheel, a guiding roller, and a second synchronous belt. The servo motor is installed on the motor bracket and drives the first synchronous belt to rotate through the gear. The first synchronous belt drives the second synchronous belt on the synchronous wheel to rotate. Two synchronous wheels are provided and are respectively installed at both ends of the guide rail beam. 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 to adjust the tightness of the first synchronous belt, and the guiding roller adjusts the position of the second synchronous belt.

[0013] For further description of the foregoing solution, the nozzle module further includes a nozzle fixing plate, a positioning bracket, and positioning holes. The nozzles are connected to the ink sacs and arranged in the center of the nozzle fixing plate. The positioning brackets are arranged at the four corners of the nozzle fixing plate. The positioning holes are arranged in the centers of the positioning brackets. A position sensing piece is further installed on the positioning brackets.

[0014] For further description of the foregoing solution, the backplane assembly further includes a cooling fan, a carrier bracket, and a board substrate. The carrier bracket connects the fixed frame and the guide rail plate. The guide rail plate is installed on the slider. The board substrate is vertically connected to the guide rail plate. The board and the cooling fan are installed on the board substrate, and the cooling fan dissipates heat from the board. The periphery of the board is further wrapped with a cover plate.

[0015] For further description of the foregoing solution, the rotary motor on the fixed frame drives the transmission shaft to drive the nozzle module to rotate. There are 4 positioning cylinder assemblies and they are fixed on the fixed frame. The positioning cylinder assembly includes a cylinder bracket, a bearing assembly, a cylinder, a positioning pin, and a position sensor. The cylinder is fixed on the cylinder bracket. The positioning pin is installed at the end of the cylinder piston. The bearing assembly is installed on the cylinder bracket and is located in front of the piston to guide the nozzle module. The position sensor is installed on the cylinder. When the position sensor detects the position sensing piece of the nozzle module, the cylinder piston pushes out to lock the positioning pin to the nozzle module.

[0016] Compared with the prior art, the present utility model has the following beneficial effects:

[0017] The present utility model can freely switch between two working modes of Multi Pass and Single Pass on the same platform, meeting various requirements from fine art reproductions to large-scale industrial printing; performing inkjet printing in the MultiPass (multi-pass printing) mode for large wide-format images; and performing inkjet printing in the Single Pass (one-pass printing) mode for narrow images, reducing the low efficiency caused by the round-trip addition and subtraction time of the carriage and the moving speed, thereby realizing continuous production and effectively improving the efficiency.

[0018] The inkjet printing mode can be freely switched according to the width and precision requirements of the image. It achieves perfect compatibility in cost control and diversified use. By integrating the two printing modes into one, the need to purchase additional dedicated equipment is reduced, and the initial investment cost is lowered. Description of the Drawings

[0039] To make the technical solutions and advantages of the present invention clearer, the following will further describe the embodiments of the present invention in detail in conjunction with the drawings.

[0040] Please refer to Figures 1-12 As shown, the present invention discloses a single-guide rail beam dual-mode adaptive rotary inkjet printing device, including a guide rail beam 1, a self-rotating printing vehicle 2, and a driving module 3. The self-rotating printing vehicle 2 is installed on the guide rail 14 of the guide rail beam 1 and reciprocates on the guide rail beam 1 through the driving module 3. As Figure 6 、 7 、8 shown, the self-rotating printing vehicle 2 includes a nozzle module 21, a backplane assembly 22, and a fixed frame 23.

[0041] As Figure 10 shown, the nozzle module 21 further includes a nozzle fixing plate 213, a positioning bracket 214, and positioning holes 215.

[0042] As Figure 9 shown, the backplane assembly 22 further includes a cooling fan 222, a carrier bracket 224, and a board substrate 226. The carrier bracket 224 is connected to the fixed frame 23 and the guide rail plate 225. The guide rail plate 225 is installed on the slider 15. The board substrate 226 is vertically connected to the guide rail plate 225. The boards 221 and the cooling fan 222 are installed on the board substrate 226, and the cooling fan 222 dissipates heat from the boards 221. The periphery of the boards 221 is also wrapped with a cover plate 227 for dust prevention.

[0043] As Figure 11 shown, the rotary motor 231 on the fixed frame 23 drives the transmission shaft 232 to drive the nozzle module 21 to rotate. In this embodiment, there are 4 positioning cylinder assemblies 233 fixed on the fixed frame 23. As Figure 12 shown, the positioning cylinder assembly 233 includes a cylinder bracket 2331, a bearing assembly 2332, a cylinder 2333, a positioning pin 2334, and a position sensor 2335. The cylinder 2333 is fixed on the cylinder bracket 2331. The positioning pin 2334 is installed at the end of the cylinder piston. The bearing assembly 2332 is installed on the cylinder bracket 2331 and is located at the front end of the piston to guide the nozzle module 21. The position sensor 2335 is installed on the cylinder 2333. When the position sensor 2335 detects the position sensing piece 216 of the nozzle module 21, the cylinder piston is pushed out to lock the positioning pin 2334 to the nozzle module 21.

[0044] Please refer to Figure 3 、 4, the guide rail beam 1 includes a guide rail beam support 11, a drag chain support 12, a guide rail 14, a slider 15, a buffer 16, an ink pipe connection groove 13, and a grating 17. The guide rail beam support 11 is used to fixedly install the guide rail beam 1 on the printing device. The drag chain support 12 is used to support the drag chain 4. The slider 15 is slidably installed on the guide rail 14 and carries the self-rotating printing vehicle 2. The buffer 16 is installed at both ends of the guide rail beam 1 to buffer the self-rotating printing vehicle 2. A distance sensor 18 is also provided near the buffer 16 to detect the position of the self-rotating printing vehicle 2. The grating 17 is installed parallel to the guide rail beam 1, and a corresponding grating reader head 223 is provided on the self-rotating printing vehicle 2 to ensure that the self-rotating printing vehicle 2 accurately moves to the desired position.

[0045] As Figure 5 shown, the drive module 3 is installed at one end of the guide rail beam 1. The drive module 3 includes a servo motor 31, a motor support 32, a gear 33, a first synchronous belt 34, a tension pulley 35, a synchronous pulley 36, a guide roller 37, and a second synchronous belt 38. The servo motor 31 is installed on the motor support 32 and drives the first synchronous belt 34 to rotate through the gear 33. The first synchronous belt 34 drives the second synchronous belt 38 on the synchronous pulley 36 to rotate. Two synchronous pulleys 36 are provided and are respectively installed at both ends of the guide rail beam 1. The second synchronous belt 38 drives the self-rotating printing vehicle 2 to move linearly on the guide rail beam 1. The tension pulley 35 is installed on the motor support 32 to adjust the tightness of the first synchronous belt 34, and the guide roller 37 adjusts the position of the second synchronous belt 38.

[0046] To understand the disclosed content of the present invention more thoroughly and comprehensively, the principle will be further explained below in combination with the usage method.

[0047] During use, the state of the spraying vehicle is the default Single Pass (one-pass printing) mode. The self-rotating printing vehicle 2 installed on the guide rail beam 1, as Figure 1 shown, this greatly improves the space for the overall nozzle cleaning, moisturizing, and ink wiping structures, provides a lot of space for subsequent maintenance, and facilitates personnel operation. When working in the Single Pass (one-pass printing) mode state, the servo motor 31 of the drive module 3 drives the first synchronous belt 34 and the second synchronous belt 38 to rotate in sequence, thereby driving the self-rotating printing vehicle 2 to move on the guide rail beam 1. When moving, the grating reader head 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 achieve continuous spraying.

[0048] When switching modes, the cylinder 2333 of the positioning cylinder assembly 233 drives the positioning pin 2334 to contract. The rotation motor 231 drives the transmission shaft 232, which in turn drives 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, pushing out the positioning pin 2334, which just inserts into the positioning hole 215 of the nozzle module 21, effectively fixing the nozzle module 21, as Figure 6 shown. After the positioning cylinder assembly 233 pushes the positioning pin 2334 to lock the nozzle module 21, through the control of the system software, the drive module 3 drives the nozzle module 21 to move, realizing the spraying in the Multi Pass mode.

[0049] In summary, the adaptive rotary spraying device of the present invention just takes the advantages of the two modes and can freely switch the spraying mode for spraying pictures of various sizes, widths and precisions.
