Description

Technical Field

[0001] The utility model belongs to the technical field of water-based digital printing, and in particular relates to a high-stability water-based digital printing transfer structure. Background Art

[0002] Water-based digital printing is an innovative printing technology that uses digital inks with water as the main solvent to print images, patterns or text directly onto various substrates through advanced digital printing equipment. Water-based digital printing has significant advantages. First, it is environmentally friendly. Compared with the oil-based inks used in traditional printing, water-based inks reduce pollution to the environment and harm to the human body. Secondly, due to the use of digital technology, there is no need for plate making, which greatly shortens the production cycle and enables fast and flexible on-demand printing to meet the needs of personalized and small-batch printing. Thirdly, the print quality is high and can present delicate colors and clear image details. In terms of application, water-based digital printing is widely used in packaging, labels, textiles, advertising and other fields, providing efficient, environmentally friendly and high-quality printing solutions for various industries.

[0003] The announcement number is "CN207875107U". A transfer device includes a transfer water tank, a water-based film traction mechanism provided at the front end of the transfer water tank, and a drainage mechanism provided at the end of the transfer water tank. The water-based film traction mechanism includes a bracket, a feed roller, and a traction roller for traction of the water-based film to the water surface. The drainage mechanism includes a water circulation part and a waste removal part. The waste removal part is located between the water circulation part and the water-based film traction mechanism; the waste removal part includes a baffle inserted into the transfer water tank, a waste suction nozzle located in front of the baffle, a fan connected to the waste suction nozzle, and a discharge pipe connected to the fan. There is a gap between the lower end of the baffle and the bottom of the transfer water tank, and the waste suction nozzle is located above the water surface. The water circulation part includes a circulating water pump provided at the end of the transfer water tank, and a circulating water pipe connected to the circulating water pump at one end and the front end of the water tank at the other end. The device can circulate water in the transfer water tank and automatically remove waste floating on the water surface.

[0004] During the application of the above-mentioned device, the spreading of the water-based film is mainly achieved by relying on the flow of water. However, in the specific application process, this method has obvious defects. During the overall use period, the stability of the water-based film is poor when it is simply spread by relying on the flow of water. On the one hand, the water flow itself is uncertain. Once ripples appear, it will interfere with the spreading of the water-based film. On the other hand, if the water-based film itself has adhesion, it will inevitably not be able to unfold stably. The inability of the water-based film to unfold stably will greatly affect its spreading and expansion effect. This unstable state will obviously lead to defects or even defective products in the subsequent printing process. In view of this, in order to improve the printing quality and ensure the smooth progress of the production process, it is urgent to improve and optimize the existing equipment. Consideration can be given to introducing a more stable film-laying mechanism, or increasing the monitoring and control means of the water flow and the state of the water-based film to improve the stability and accuracy of the spreading of the water-based film.

[0011] As an optimal technical solution, a fixing plate is fixedly installed on the side of the transfer water tank away from the unwinding mechanism, and a sewage suction nozzle is fixedly installed on the upper end of the fixing plate.

[0012] As an optimal technical solution, a connecting pipe is fixedly installed on the outer end of the sewage suction nozzle, and a threaded joint is fixedly connected to the outer end of the connecting pipe.

[0013] As an optimal technical solution, the unwinding mechanism includes a vertical plate, which is fixedly installed on the side of the top of the transfer water tank away from the suction nozzle.

[0025] refer to Figures 1 to 5, a high-stability water-based digital printing transfer structure of this embodiment includes a transfer water tank 1, a reeling mechanism 2 is fixedly installed on one side of the top of the transfer water tank 1, a spreading mechanism 3 is fixedly installed on the upper front end of the transfer water tank 1, and a driving mechanism 6 is fixedly installed on the bottom of the transfer water tank 1. The output end of the driving mechanism 6 is connected to the side of the transfer water tank 1 close to the reeling mechanism 2, and the input end of the driving mechanism 6 is connected to the side of the transfer water tank 1 away from the reeling mechanism 2;

[0026] The driving mechanism 6 includes a water pump 61, and the input and output ends of the water pump 61 are fixedly installed with a water guide frame 62. The water pump 61 is fixedly installed in the middle of the bottom of the transfer water tank 1. The water guide frame 62 at the input end of the water pump 61 is connected to the side of the transfer water tank 1 away from the unwinding mechanism 2, and the water guide frame 62 at the output end of the water pump 61 is connected to the side of the transfer water tank 1 close to the unwinding mechanism 2. A drain valve 63 is fixedly installed at the lower end of one water guide frame 62, and a drain pipe 64 is fixedly installed at the output end of the drain valve 63. The transfer water tank 1, as a core component, provides a stable working environment for the entire transfer process. The unwinding mechanism 2 on the top side facilitates the installation and replacement of the water-based film and improves work efficiency. The spreading mechanism 3 at the upper end of the front side can ensure that the water-based film is stably spread on the transfer water tank 1 In the figure, the foundation is laid for high-quality printing transfer, and the driving mechanism 6 at the bottom plays a key role. The water pump 61 realizes the circulation of water in the transfer water tank 1 through the water guide frames 62 at both ends. On the one hand, this circulating water flow enables the aqueous film to float stably when it contacts the water flow, which is convenient for the spreading mechanism 3 to clamp and improve the stability and accuracy of the spreading; on the other hand, after the watermark is completed, the water flow can push the remaining dye to a specific position to facilitate the sewage suction treatment. The drain valve 63 and the drain pipe 64 at the lower end of the water guide frame 62 facilitate drainage operations when needed, which enhances the operability and flexibility of the equipment. Overall, the structure has the advantages of stability, efficiency, convenience of operation, and complete functions, and can provide a reliable solution for water-based digital printing transfer.

[0027] refer to Figure 1 and Figure 3The spreading mechanism 3 includes a side rail 31, which is fixedly installed on the upper end of the front side of the transfer tank 1. A first motor 32 is fixedly installed on one end of the side rail 31. The output end of the first motor 32 passes through the side rail 31 and is fixedly installed with a one-way screw rod 33. The one-way screw rod 33 is rotatably connected to the inside of the side rail 31. The outer surface of the one-way screw rod 33 is threadedly connected to a slider 34. The slider 34 is slidably connected to the inside of the side rail 31. A clamping assembly 35 is fixedly installed on the top of the slider 34. The clamping assembly 35 includes a connecting rod. The connecting arm 351 is fixedly mounted on the top of the slider 34. The end of the connecting arm 351 is fixedly mounted with a vertical rail 352. The internal rotation of the vertical rail 352 is connected to a bidirectional screw rod 353. The two ends of the bidirectional screw rod 353 have opposite screw threads. Both ends of the bidirectional screw rod 353 are threadedly connected to a movable block 354. A clamping plate 355 is fixedly mounted on the side of the movable block 354 close to the transfer tank 1. A second motor 356 is fixedly mounted on the top of the vertical rail 352. The output end of the second motor 356 The top of the bidirectional screw rod 353 is fixedly connected, and the side rail 31 is fixed to the upper end of the front of the transfer water tank 1, providing a stable installation foundation for the spreading operation. The first motor 32 drives the unidirectional screw rod 33, so that the slider 34 can slide accurately inside the side rail 31, thereby realizing flexible adjustment of the position of the clamping assembly 35. The connecting arm 351 in the clamping assembly 35 connects the slider 34 and the vertical rail 352 to ensure the stability of the structure. The two ends of the bidirectional screw rod 353 inside the vertical rail 352 have opposite threads. Under the drive of the second motor 356, the movable blocks 354 at both ends can move toward or away from each other. The splint 355 on the movable block 354 can stably clamp the water-based film. By precisely controlling the rotation of the bidirectional screw rod 353, it can be ensured that the clamping force of the splint 355 on the water-based film is uniform and appropriate. This design enables the spreading mechanism 3 to spread the water-based film more stably, improves the quality and stability of the watermark, and provides an efficient and reliable spreading solution for water-based digital printing transfer.

[0028] refer to Figure 1The outer end of the connecting pipe 7 is fixedly connected with a threaded joint 8. The fixing plate 4 and the suction nozzle 5 are arranged on the side of the transfer water tank 1 away from the unwinding mechanism 2. The fixing plate 4 and the suction nozzle 5 are fixedly installed on the side of the transfer water tank 1 away from the unwinding mechanism 2. The fixing plate 4 and the suction nozzle 5 are fixedly connected with the connecting pipe 7. The outer end of the connecting pipe 7 is fixedly connected with a threaded joint 8. The fixing plate 4 and the suction nozzle 5 arranged on the side of the transfer water tank 1 away from the unwinding mechanism 2 have many advantages. The fixing plate 4 provides a stable installation position for the suction nozzle 5 to ensure that it will not shake or shift during operation. The suction nozzle 5 can effectively collect the dye and waste remaining after the watermark is completed. The threaded joint 8 at the outer end of the connecting pipe 7 can be conveniently connected to an external suction pump to achieve the function of quickly sucking out waste. This design enables the transfer water tank 1 to maintain a clean working environment during the water-based digital printing transfer process, avoiding waste from causing adverse effects on subsequent printing transfers. At the same time, the design of quick connection to external equipment also improves the convenience and flexibility of use of the equipment, and provides a strong guarantee for efficient and stable printing transfer operations.

[0029] refer to Figures 1-4The unwinding mechanism 2 includes a vertical plate 21, which is fixedly mounted on the side of the top of the transfer water tank 1 away from the sewage suction nozzle 5. The upper end of the vertical plate 21 is rotatably connected to a turntable 22. A clamping assembly 23 is fixedly mounted on the side of the turntable 22 close to the transfer water tank 1. The side of the vertical plate 21 close to the sewage suction nozzle 5 is rotatably connected to two guide rollers 24. The upper end of the vertical plate 21 is mounted with a water-based film roller 25 through the clamping assembly 23. The clamping assembly 23 includes a concave seat 231. The concave seat 231 is fixedly mounted on the side of the turntable 22 close to the transfer water tank 1. An insert 232 is inserted into the inner side of the concave seat 231. A frame 234 is fixedly installed on one side of 231, and a limit spring 235 is fixedly connected to the inner side of the frame 234. The end of the limit spring 235 is fixedly connected to a clamping block 233. A clamping slot 236 is opened on the side of the insert block 232 near the limit spring 235. The end of the clamping block 233 is inserted into the inner side of the clamping slot 236. A connecting rod 237 is fixedly connected to the outer side of the clamping block 233. The outer end of the connecting rod 237 passes through the frame 234 and is fixedly installed with a bridge handrail 238. The overall cross-sectional shape of the clamping block 233 is a right triangle. The inclined surface of the clamping block 233 is set at the upper end of the side near the clamping slot 236. The water-based film roller 25 is fixedly installed on the side of the insert block 232 close to the transfer water tank 1. The vertical plate 21 provides a stable support for the entire unwinding mechanism 2. The turntable 22 can be flexibly rotated to facilitate adjustment of the angle of the water-based film roller 25. The concave seat 231 in the clamping assembly 23 cooperates with the insert block 232 to achieve rapid installation and fixation of the water-based film roller 25. When the insert block 232 is inserted into the concave seat 231, the insert block 232 contacts the inclined surface of the clamping block 233. The clamping block 233 is forced to compress the limit spring 235 to contract. When the clamping block 233 contacts the clamping slot 236, the limit spring 235 is reset to reset the clamping block 2 33 pops into the card slot 236, so that the insert block 232 is stably located inside the concave seat 231, ensuring that the water-based film roller 25 is firmly installed. When the water-based film roller 25 needs to be replaced, it is only necessary to pull out the bridge handrail 238 and drive the card block 233 out of the card slot 236 through the connecting rod 237 to achieve quick disassembly and assembly, reducing the time required for replacement and improving printing efficiency. The two guide rollers 24 can guide the water-based film to smoothly enter the water surface of the transfer tank 1, providing a good start for the subsequent spreading and watermarking process. This unwinding mechanism 2 is cleverly designed and easy to operate, greatly improving the practicality and stability of the equipment.

[0030] Principle and advantages of use: During the use of this device, by setting the unwinding mechanism 2, the insert block 232 on the water-based film roller 25 can be inserted into the inner side of the concave seat 231 during use. During the insertion process, the insert block 232 contacts the inclined surface of the card block 233, so that the card block 233 is subjected to force, thereby compressing the limit spring 235 to contract. When the card block 233 contacts the card slot 236, the limit spring 235 quickly resets and bounces the card block 233 into the interior of the card slot 236. In this way, the card block 232 can be assisted to be installed, so that the insert block 232 is stably located in the concave seat. After the installation is completed, the water-based film is placed on the guide roller 24 and then placed on the water surface of the transfer water tank 1. At the same time, the spreading mechanism 3 is used to assist in pulling to achieve spreading. When the water-based film on the outer surface of the water-based film roller 25 is used up, it is only necessary to pull the bridge handrail 238 to drive the connecting rod 237 to pull the block 233 out of the slot 236. At this time, the water-based film roller 25 can be quickly disassembled and replaced. This design makes the device extremely convenient in the subsequent disassembly and replacement process, greatly reducing the time required for replacement, thereby effectively improving printing efficiency.

[0031] By setting up the spreading mechanism 3, when the water-based film contacts the water surface during use, the driving mechanism 6 is started to run. At this time, the input end of the water pump 61 pumps water and discharges it through the output end. At the same time, the water guide frame 62 is used to pump water back, so that water can circulate inside the transfer water tank 1. The water flow always flows toward one side of the suction nozzle 5. This can prompt the water-based film to float toward the other side at all times when it contacts the water flow, so that the spreading mechanism 3 can clamp the water-based film more stably. During the spreading process, the water-based film can be watermarked after it dissolves in the water. After the watermark is completed, the water flow can push The remaining dye flows to the sewage suction nozzle 5, which is connected to the external sewage suction pump through the threaded joint 8, so that the waste material can be quickly sucked out. During use, only the external water pipe and the liquid level sensor are needed to quantitatively replenish water in the transfer water tank 1 to maintain a consistent water level, thereby achieving rapid watermark processing. It can be seen that the device as a whole has stable spreading and sewage suction functions, and the processing efficiency is more efficient. The liquid level sensor and the external water replenishing device are both existing technologies, which are widely used and belong to very conventional known technical means, so they will not be described here.

[0032] By setting up a spreading mechanism 3, during use, the device can start the first motor 32 to drive the one-way screw rod 33, driving the slider 34 to slide toward one side of the spreading mechanism 3. During this period, the second motor 356 can be started to drive the double-wire screw rod to rotate. Since the threads at both ends of the two-way screw rod 353 are rotated in opposite directions, the two movable blocks 354 can be driven to move in opposite directions, thereby causing the two clamping plates 355 to separate from each other. When the clamping plates 355 move to the top and bottom of the water-based film, the second motor 356 is started to drive the two-way screw rod 353 to reverse, thereby driving the two movable blocks 354 to move inward. At this time, the clamping plates 355 can clamp the water-based film. By starting the first motor 32 to reverse, the one-way screw rod 33 can be driven to drive the slider 34 away from one side of the unwinding mechanism 2. At this time, the water-based film can be pulled by the clamping plates 355 to be stably spread inside the transfer water tank 1. It can be seen that the device adopts the spreading mechanism 3 for guidance, which can more stably spread the watermark and significantly improve the stability of the overall watermark.
