Technical Field
[0001] This utility model relates to the field of water-coated transfer printing, and more particularly to a water tank for water-coated transfer printing. Background Technology
[0002] Water transfer printing is a printing technology widely used for product surface decoration. It involves transferring patterns or designs onto a thin film on the surface of water, and then using the buoyancy and surface tension of the water to transfer the patterns to the surface of the object to be treated, forming a unique decorative effect. The whole process includes placing the film in water, activating the pattern on the film, using surface tension to make the pattern evenly cover the surface of the object, and finally using drying and curing treatments to make the pattern firmly adhered.
[0003] Water transfer printing is widely used in automotive parts, mobile phone cases, sporting goods, and household goods. It can achieve complex patterns and diverse decorative effects, and is especially suitable for curved and irregularly shaped objects. The advantages of this technology include high efficiency, environmental friendliness, high repeatability, and the ability to achieve personalized customization. However, it has certain requirements for the operating environment and equipment, and it is necessary to control factors such as water temperature, film material selection, and printing time.
[0004] However, the water tanks in current water transfer printing are just simple water tanks without a water circulation system. The film residue left on the water surface is not easy to clean, and the activator residue left on the water surface is not easy to remove. If water transfer printing is to be operated continuously, fresh water needs to be replenished constantly, resulting in a great waste of water resources. Therefore, a water transfer printing water tank is proposed to solve the above problems. Utility Model Content

[0032] The filtration circulation assembly includes a filter plate 5, a fixing groove 11, and a water pump 2. The filter plate 5 is externally slidably connected to the inner wall of the first filter groove 6. The fixing groove 11 is externally fixedly connected to the inner wall of the second filter groove 9, and filter cotton 12 is slidably connected inside the fixing groove 11. The water pump 2 is externally fixedly connected to the bottom wall of the second filter groove 9. A water supply pipe 3 is fixedly connected to the output end of the water pump 2, and a nozzle 4 is fixedly connected to the output end of the water supply pipe 3. The filter plate 5 is used to filter out larger membrane paper residues. The fixing groove 11 is used to facilitate the installation of the filter cotton 12. The filter cotton 12 is used to filter smaller membrane paper residues, thus achieving secondary filtration of the water. The water pump 2 is used to pressurize the water. The water supply pipe 3 is used to deliver water to the nozzle 4. The nozzle 4 is used to re-spray water into the main body of the water tank. The water sprayed from the nozzle 4 can accelerate the pushing of membrane paper residues on the water surface towards the filter plate 5 for filtration. The right side of the main body of the water tank 1 is equipped with... There is an electrical box 14, which is electrically connected to the water pump 2. The electrical box 14 is equipped with a temperature control switch for the heating element, which is used to control the operation of the water pump 2 and the temperature control of the heating rod installed at the bottom of the water tank. The function of the heating element is to ensure a constant water temperature and achieve the ideal working state for water transfer printing. The drain pipe 8 is installed outside the filter tank 2 9, so that the water in the filter tank 1 6 is directly transported to the filter tank 2 9. The water supply pipe 3 runs through the front of the filter tank 2 9 and is fixedly connected to the inside of the water tank body 1 to keep the water supply pipe 3 stable. The nozzle 4 is fixedly connected to the inside of the water tank body 1 to keep the nozzle 4 stable. The filter tank 1 6 is installed directly above the filter tank 2 9, so that water enters the filter tank 1 6 and the filter tank 2 9 in sequence. The filter cotton 12 is sleeved inside the filter tank 2 9 to keep the filter cotton 12 stable.
[0033] Reference Figures 1-3The extension component includes two self-locking folding hinges 15. The inner side of the self-locking folding hinges 15 is fixedly connected to the outside of the water tank body 1. A folding operating table 10 is fixedly connected to the outside of the two self-locking folding hinges 15 on the same side. The self-locking folding hinges 15 are used to connect and support the folding operating table 10. The self-locking folding hinges 15 can be unfolded to 90° and then lock themselves. The folding operating table 10 is used to place workpieces to facilitate workers to perform transfer operations. The outside of the folding operating table 10 abuts against the outside of the water tank body 1 to keep the folding operating table 10 stable.
[0034] Working principle: When using the water tank body 1 for water transfer printing, first unfold the two folding operating tables 10 on both sides, lift the folding operating tables 10 upwards to rotate the self-locking folding hinges 15 until the folding operating tables 10 and the water tank body 1 are on the same horizontal line. At this time, the self-locking folding hinges 15 will automatically lock and fix the folding operating tables 10. Then the water transfer printing work can begin. The pattern is attached to the water surface. Take the workpiece from one of the folding operating tables 10 and slowly put the workpiece into the water until the workpiece is attached with the pattern, completing the transfer work. Place the transferred workpiece on the other folding operating table 10. At the same time, the electrical box 14 controls the water pump 2 to work, transporting the water collected in the filter tank 2 9 along the water supply pipe 3 to the nozzle 4, and then spraying it from the nozzle 4. The water sprayed out simultaneously drives the water flow towards the filter plate 5, and the membrane paper residue remaining on the water surface moves towards the filter plate 5 at the same time. The water and membrane paper residue are filtered together by the filter plate 5, removing larger impurities. The water will directly enter the first filter tank 6, and then flow along the drain pipe 8 into the second filter tank 9 for collection. When the water pump 2 is restarted, the water will be filtered by the filter cotton 12, intercepting smaller impurities, realizing secondary filtration and preventing impurities from entering the water pump 2 and clogging the water pump 2 and the nozzle 4. This achieves water filtration circulation, effectively saving water resources. The wastewater collected in the second filter tank 9 can be discharged directly from the second drain outlet 13. At the same time, the filter plate 5 and the filter cotton 12 can be directly removed for individual cleaning or replacement, making the operation convenient and labor-saving.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
