[0020] Reference Figures 1 to 4 The following are several embodiments of the digital printing device for edge sealing tape of this utility model.

[0021] like Figures 1 to 4 As shown, the digital printing device for edge sealing tape according to this embodiment of the present invention includes a frame 100, a printer body 200, and a conveyor belt 110. The printer body 200 includes multiple ink tanks 210 and multiple print heads 220. The multiple ink tanks 210 are spaced apart on the frame 100, and the multiple print heads 220 are connected to the multiple ink tanks 210. The multiple print heads 220 are spaced apart along the length direction of the frame 100. The multiple ink tanks 210 are used to store different pigments and provide ink to the print heads 220. The conveyor belt 110 is located below the print heads 220 and is used to drive the edge sealing tape to be conveyed along the length direction of the frame 100.

[0022] When the printing device is working, the conveyor belt 110 runs continuously, driving the sealing tape to pass through at a constant speed along the length of the frame 100; at the same time, multiple print heads 220, which are spaced apart along the conveying path, accurately spray ink from ink tanks 210 containing ink of different colors onto the surface of the sealing tape passing below. By performing multi-color overprinting simultaneously during the conveying process, a complete color pattern is formed on the sealing tape.

[0023] In addition, the printhead 220 is equipped with a UV curing lamp. After the printhead 220 sprays special UV ink onto the surface of the moving edge sealing tape, the conveyor belt 110 immediately sends the edge sealing tape with the undried ink to the UV curing lamp. At this time, the UV curing lamp emits strong ultraviolet rays of a specific wavelength, which instantly irradiate and penetrate the ink layer, triggering a photochemical reaction. This causes the resin and monomer components in the ink to rapidly change from a liquid state to a solid state, thus instantly curing into a hard ink film. This reduces problems such as pattern smudging, smudging, or misregistration caused by undried ink, ensuring the high definition and wear resistance of the printed pattern. Furthermore, due to the instant curing characteristic of the UV curing lamp, the edge sealing tape can be immediately rolled up or further processed after printing, improving the efficiency of continuous production. The UV curing lamp can be fixed on one side of the printhead 220 in the conveyor belt 110's conveying direction, allowing the UV curing lamp to move with the printhead 220 for precise curing of the printed edge sealing tape.

[0024] like Figures 1 to 3 As shown, in some embodiments, the printing apparatus further includes a tensioning assembly 300, which includes a take-up reel 310 and an unwinder 320. The take-up reel 310 is used to take up the edge sealing tape, and the unwinder 320 is used to unwind the edge sealing tape. The conveyor belt 110 has an inlet end 111 and an outlet end 112. The take-up reel 310 is located at the outlet end 112, and the unwinder 320 is located at the inlet end 111. The unwinder 320 continuously releases the edge sealing tape to be printed, so that the edge sealing tape smoothly enters the inlet end 111 of the conveyor belt 110. Subsequently, the conveyor belt 110 pulls the edge sealing tape through multiple print heads 220 in sequence for precise multi-color inkjet printing. After printing is completed, the printed edge sealing tape sent out from the outlet end 112 of the conveyor belt 110 is synchronously and uniformly wound up by the take-up reel 310. The unwinding and rewinding actions are coordinated with the conveyor speed of the conveyor belt 110 to provide and maintain appropriate tension for the sealing tape, thereby reducing the possibility of slippage of the sealing tape throughout the printing process. The rewinder 310 and the unwinder 320 are existing winding and unwinding devices, and this embodiment of the utility model does not impose any particular limitation on them.

[0025] like Figures 1 to 4As shown, in some embodiments, the digital printing device further includes a stop plate 400, which is disposed on the frame 100. When the print head 220 stops printing, the print head 220 moves above the stop plate 400, so that the stop plate 400 receives the ink dripping from the print head 220. When the print head 220 stops printing, the print head 220 moves above the stop plate 400. Any ink that may drip from the print head 220 will be received by the stop plate 400, effectively preventing the ink from the print head 220 from dripping onto the conveyor belt or the printed edge sealing tape. Support plates 410 are provided on both sides of the stop plate 400. The support plates 410 support the stop plate 400, ensuring that the stop plate 400 remains stable when subjected to ink drips, without shifting or vibrating. This reliably prevents ink from contaminating the equipment and products below, improving the convenience of device maintenance and operational reliability. A receiving groove is formed between the support plate 410 and the stop plate 400, which can catch the dripping ink. It should be noted that the height of the stop plate 400 is lower than the height of the transmission belt to avoid collision between the print head 220 and the stop plate 400. Multiple engaging protrusions 411 are spaced apart at the bottom of the support plate 410, and multiple engaging slots are correspondingly provided on the frame 100. By engaging the protrusions 411 into the engaging slots, the stop plate 400 can be fixed to the frame 100.

[0026] like Figures 1 to 4 As shown, in some embodiments, the printer body 200 further includes a print drive 500, which is disposed on the frame 100 and used to drive the print head 220 to move along the width direction of the frame 100; the stop plate 400 and the conveyor belt 110 are disposed along the width direction of the frame 100; during printing, the print drive 500 drives the print head 220 to reciprocate along the width direction of the frame 100, while the conveyor belt 110 drives the sealing tape forward along the length direction; this allows the print head 220 to scan relative to the surface of the sealing tape, thereby accurately covering the sealing tape with ink. When printing stops, the print drive 500 moves the print head 220 laterally to directly above the stop plate 400, which is disposed parallel to the width direction of the conveyor belt 110, so that the stop plate 400 can catch any dripping ink, thereby achieving precise control of the printing range. The print drive 500 can be a linear motor.

[0027] like Figures 1 to 4As shown, in some embodiments, the length of the stop plate 400 along the length direction of the frame 100 is greater than or equal to the length of the conveyor belt 110; when the print head 220 stops working, no matter where the print head 220 stops along the length direction of the frame 100, it can move directly along the width direction to the top of the stop plate 400 to avoid it, so that the ink dripping from the print head 220 can be received by the stop plate 400 below, which enhances the anti-fouling reliability of the printing device.

[0028] like Figures 1 to 4 As shown, in some embodiments, the width of the stop plate 400 along the width direction of the frame 100 is greater than or equal to the width of the print head 220. This ensures that the print head 220 can be completely covered by the stop plate 400, guaranteeing that ink dripping from the print head 220 can drip onto the stop plate 400. This reduces ink contamination of the conveyor belt 110 or other components of the equipment, ensuring the cleanliness and safety of the device. The stop plate 400 is strip-shaped; by limiting the width of the stop plate 400, its floor space can be reduced.

[0029] like Figures 1 to 4 As shown, in some embodiments, the digital printing device further includes an air suction assembly 600 and a negative pressure chamber 700, the negative pressure chamber 700 being disposed on the frame 100; the negative pressure chamber 700 has an opening extending along the length of the frame 100; a conveyor belt 110 conveys air on the negative pressure chamber 700, and the conveyor belt 110 covers the opening; the conveyor belt 110 has an adsorption port connected to the interior of the negative pressure chamber 700; the air suction assembly 600 is used to perform air extraction on the negative pressure chamber 700; when the printing device is working, the air suction assembly 600 is activated and continuously extracts air from the negative pressure chamber 700, creating a negative pressure inside the negative pressure chamber 700, resulting in an adsorption force on the upper surface of the conveyor belt 110. When the edge sealing tape is driven by the conveyor belt 110, the edge sealing tape is flatly adsorbed onto the surface of the conveyor belt 110 by the adsorption force, thereby reducing the possibility of the edge sealing tape shifting, lifting, or vibrating during the printing process, providing a foundation for the print head 220 to achieve high-quality inkjet printing.

[0030] like Figures 1 to 4 As shown, in some embodiments, multiple adsorption ports are provided, and these ports are evenly distributed on the conveyor belt 110. The suction component 600 continuously draws air from the negative pressure box 700 to create negative pressure, thereby generating a uniform adsorption force on the entire plane of the conveyor belt 110 carrying the edge sealing tape. This ensures that the edge sealing tape can be stably adsorbed and fixed on the conveyor belt 110, reducing the possibility of warping or displacement due to insufficient local adsorption force.

[0031] like Figures 1 to 4As shown, in some embodiments, the air intake assembly 600 includes an air pump 610 and an air delivery pipe, the air delivery pipe being connected to the air pump 610 and the negative pressure box 700; the air pump 610 serves as a power source, and air is continuously drawn from the negative pressure box 700 through the air delivery pipe connected to the air pump 610, thereby forming and maintaining a stable negative pressure state within the negative pressure box 700.

[0032] like Figures 1 to 4 As shown, in some embodiments, the digital printing device also includes a cover 800, which covers the outside of the printer body 200. By covering the outside of the printer body 200, the cover 800 forms a relatively enclosed working space. This reduces the amount of dust and impurities from the external environment falling onto components such as the print head 220 and the conveyor belt 110. At the same time, it can reduce the noise generated during printer operation to a certain extent and reduce the risk of operators accidentally contacting moving parts inside the printing device. This improves print quality and enhances the safety of device operation.

[0033] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined in this application.
