Technical Field

[0001] The utility model relates to the technical field of digital printers, in particular to a digital printer with an automatic printing mode switching structure. Background Art

[0002] In today's printing industry, cardboard digital printers occupy a vital position. They play a key role in many fields such as packaging printing, advertising display and personalized customization. Different printing tasks often require different printing modes to achieve the best results. For example, in some large-scale batch printing jobs with extremely high speed requirements, the single-pass printing mode can show extremely significant advantages. It can complete the printing of the entire image in a single scan process, greatly improving printing efficiency and saving valuable time for enterprises in large-scale production. In those personalized printing tasks with higher precision requirements and more complex patterns, the scanning and printing mode can better highlight its value. This mode can present every detail of the pattern through multiple scans and prints, making the final printed product more exquisite and meeting customers' high requirements for personalized customization.

The funnel-shaped structure of the lower pipe is conducive to the collection of dust and impurities, and can make the impurities falling from the branch pipe enter the dust collection bucket more smoothly. The threaded locking connection between the lower pipe and the dust collection bucket facilitates the disassembly and cleaning of the dust collection bucket. When the dust collection bucket is full, it can be easily unscrewed for disposal;

[0022] 2. The digital printer with an automatic printing mode switching structure has a threaded connection between the translation seat and the screw and a sliding connection with the slide rail.

[0033] The adsorption assembly 4 includes a branch pipe 401, a negative pressure pipe 402, a lower connecting pipe 403, a filter 404, and a dust collection bucket 405. The upper end of the branch pipe 401 is fixedly connected to the negative pressure pipe 402.

The lower end of the lower connecting pipe 403 is provided with a dust collection bucket 405.

[0034] The rotating assembly 12 includes a translation seat 1201, a fixed seat 1202, a worm 1203, a motor 2 1204 and a worm gear 1205. The lower end of the translation seat 1201 is fixedly connected to the fixed seat 1202, the center of the fixed seat 1202 is rotatably connected to the worm 1203, the front end of the fixed seat 1202 is fixedly connected to the motor 2 1204, and the lower end of the translation seat 1201 is rotatably connected to the worm gear 1205.

[0035] Specifically, the negative pressure hole 3 is interconnected with the negative pressure tube 402, and the filter 404 is made of inorganic fiber filter cotton. Advantageously, the connection between the negative pressure hole 3 and the negative pressure tube 402 allows for effective utilization of the negative pressure adsorption function during the printing process. This prevents the cardboard from shaking or shifting due to the printing operation, ensuring printing accuracy. The filter 404 is made of inorganic fiber filter cotton, which has excellent filtering properties and effectively intercepts dust and impurities, preventing them from entering the negative pressure system. This ensures the stability and continued effectiveness of negative pressure adsorption, prevents dust clogging from affecting the normal operation of the adsorption component 4, and extends its service life.

[0036] Specifically, the lower pipe 403 has a funnel-shaped structure and is threadedly connected to the dust collection bucket 405. The main pipe 5 is fixedly connected to the output of an external vacuum pump. Advantageously, the funnel-shaped structure of the lower pipe 403 facilitates the collection of dust and impurities, allowing impurities falling from the branch pipe 401 to enter the dust collection bucket 405 more smoothly. The threaded, locked connection between the lower pipe 403 and the dust collection bucket 405 facilitates the removal and cleaning of the dust collection bucket 405.

[0037] Example 2: Figure 2-7 As shown, as an improvement to the previous embodiment.

[0038] Specifically, the translation seat 1201 is threadedly connected to the screw rod 10, and the translation seat 1201 is slidably connected to the slide rail 9. Advantageously, the threaded connection between the translation seat 1201 and the screw rod 10 and the slidable connection with the slide rail 9 enable the translation seat 1201 to perform stable linear motion along the slide rail 9 when the motor 11 drives the screw rod 10 to rotate, providing accurate position control for the movement of the inkjet carriage 16, thereby ensuring the accuracy of the inkjet position during printing. When the printer body 1 is in scanning and printing mode, the inkjet carriage 16 is in a vertical position.

[0039] Specifically, the worm 1203 and the worm wheel 1205 are meshingly connected, and the worm wheel 1205 is fixedly connected to the carrier 13. Advantageously, when switching to single-pass printing mode is required, the motor 11 is started to drive the inkjet carriage 16 forward, providing space for the inkjet carriage 16 to rotate. The motor 2 1204 then drives the worm 1203 to rotate. Due to the meshing connection between the worm 1203 and the worm wheel 1205, the carrier 13 is driven to rotate until the inkjet carriage 16 rotates 90 degrees and is in a horizontal position, allowing printing in single-pass printing mode. The transmission method of the worm 1203 and the worm wheel 1205 is self-locking, ensuring that the carrier 13 remains stable after being adjusted to the desired angle. Manual switching of the printing mode is unnecessary, saving manpower and improving the efficiency of printing mode switching.

[0040] Specifically, the chute 14 is slidably connected to the slide bar 17. The advantage is that when the inkjet frame 16 needs to be replaced or maintained, the inkjet frame 16 can be smoothly drawn out along the chute 14, which is easy to operate.

[0041] Specifically, the diameter of the fixing hole 19 is the same as the diameter of the circular hole 15. Advantageously, the same diameter of the fixing hole 19 and the circular hole 15 facilitates the use of bolts through the fixing hole 19 and the circular hole 15 to more securely secure the inkjet carriage 16 within the carrier 13. This effectively prevents displacement of the inkjet carriage 16 due to vibration and other factors during printer operation, ensuring accurate inkjet positioning and thus improving print quality.

[0042] Working principle: When the printer body 1 is in the scanning and printing mode, the inkjet carriage 16 is in the vertical position. When it is necessary to switch to the single-pass printing mode, the motor 11 is started to drive the inkjet carriage 16 to move forward to provide space for the rotation of the inkjet carriage 16. The motor 2 1204 drives the worm 1203 to rotate. Due to the meshing connection between the worm 1203 and the worm gear 1205, the carrier 13 is driven to rotate until the inkjet carriage 16 rotates 90 degrees and is in the horizontal position. Then the single-pass printing mode can be performed. For printing operations in the pass printing mode, the transmission method of the worm 1203 and the worm wheel 1205 is self-locking, which can ensure that the carrier 13 remains stable after being adjusted to the required angle. The switching of the printing mode does not need to be done manually, which saves manpower and improves the efficiency of the printing mode switching. The main line 5 is fixedly connected to the output end of the external vacuum pump to provide a stable negative pressure source for the entire adsorption component 4. The negative pressure hole 3 is connected to the negative pressure pipe 402, so that the negative pressure adsorption function can be effectively utilized during the printing process. When printing cardboard, it can prevent the cardboard from shaking or moving due to the printing operation, ensuring printing accuracy. The filter 40 4 adopts inorganic fiber filter cotton, which has good filtering performance and can effectively intercept dust and impurities to prevent them from entering the negative pressure system, thereby ensuring the stability of negative pressure adsorption, preventing the normal operation of the adsorption component 4 from being affected by dust blockage, and extending its service life. The funnel-shaped structure of the lower connecting pipe 403 is conducive to the collection of dust and impurities, and can make the impurities falling from the branch pipe 401 enter the dust collection barrel 405 more smoothly. The threaded locking connection between the lower connecting pipe 403 and the dust collection barrel 405 is convenient for disassembly and cleaning of the dust collection barrel 405. When the dust collection barrel 405 is full, it can be easily unscrewed for disposal.
