Description

Technical Field

[0001] This utility model relates to the field of digital printing technology, specifically to a water-based coating digital direct-to-garment printing device. Background Technology

[0002] Digital printing machines, also known as universal printers, are high-tech digital printing equipment that uses inkjet printing without physical contact. They can print on any material and irregular soft or hard objects, and have a wide range of applications.

[0003] A water-based coating is required in digital printing. As the name suggests, water-based coating is a coating that uses water as a medium. When using it, the water-based coating is pre-mixed. After the adjustment is completed, the coating is delivered to the print head of the digital printing machine by a delivery pump. However, due to the high temperature in the factory, the water in the pre-mixed water-based coating will slowly evaporate, resulting in the coating becoming thick.

[0004] A search revealed Chinese patent application number 202123274160.X, "A Direct Injection Connection Mechanism for Digital Printing Water-Based Coatings," belonging to the field of digital printing equipment technology. This invention, by setting up several inlet and outlet pipes, can deliver water-based coatings with varying color ratios, meeting the diverse color requirements of digital printing machines. By connecting an external pipeline to a second quick-connect fitting, liquid water is supplied to the dispensing box. The liquid water is then transported to the corresponding inlet pipes through several connecting pipes on the dispensing box, achieving the mixing of liquid water with the water-based coating in the inlet pipes. A solenoid valve controls the amount of liquid water entering. A motor drives two lead screws to rotate in the same direction. The rotation of the lead screws moves a sliding sleeve, which in turn moves a rolling rod. The movement of the rolling rod causes a ball to roll on a transition pipe, achieving the effect of the ball rolling and pressing the water-based coating inside the transition pipe. This ensures that the added liquid water is fully mixed with the pre-mixed water-based coating and prevents it from easily condensing.

[0005] In the above technical solution, in order to fully mix water-based coatings and liquid water, a transition tube of a certain length is required, and a reciprocating extrusion component is used to extrude the transition tube to mix the two solutions together. However, this method results in a long pipe, making the entire device larger in size. At the same time, the mixing efficiency between solutions is relatively low when using the extrusion method, making it inconvenient to use. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a water-based coating digital direct-to-garment printing device, which solves the problems of large overall device size and low mixing efficiency between solutions due to the use of extrusion pipes, making it inconvenient to use.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A digital direct-to-garment printing device for water-based coatings includes a connector, an auxiliary connecting pipe, a solenoid valve, and a built-in flow disruptor. The built-in flow disruptor is installed in the internal cavity of both the liquid inlet pipe and the liquid inlet branch pipe of the connector. The conical head of one end of the built-in flow disruptor is oriented towards the direction of liquid inlet. The auxiliary connecting pipe connected to the liquid inlet branch pipe is equipped with a solenoid valve. The built-in flow disruptor is composed of multiple spiral guide plates arranged in a ring array. The embedding ring at one end of the spiral guide plate is fixedly embedded in the pipe wall at the corresponding position inside the connector.

[0009] Furthermore, the inlet pipe end of the connector is provided with a first quick-connect fitting, and the outlet pipe end of the connector is provided with a second quick-connect fitting.

[0010] One end of the auxiliary connecting pipe is fixedly connected to the end of the liquid inlet branch pipe, and the other end of the auxiliary connecting pipe is equipped with a third quick-connect fitting.

[0011] The inlet branch pipe and the auxiliary connecting pipe have the same inner diameter, and their ends are heat-fused together.

[0012] Furthermore, the embedded ring of the built-in baffle is fixedly embedded in the pipe wall at the corresponding position inside the liquid inlet pipe and the liquid inlet branch pipe, and the anti-slip bushing is fitted on the outer wall of the embedded ring, and the end of the tapered head of the built-in baffle is a spherical arc surface.

[0013] Compared with the prior art, this utility model provides a water-based coating digital direct-to-garment printing device, which has the following beneficial effects:

[0014] This invention uses a connector to replace the original transition tube. When the liquid enters the connector, it is blocked and turbulent by the built-in flow deflector, causing it to flow in a spiral shape. This facilitates the mutual disturbance of the two liquids during the parallel flow process, thereby fully mixing them together. While reducing the overall size of the device, the mixing efficiency is improved. The entire device is small in size, simple in structure, and easy to use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] like Figure 1 , Figure 2 and Figure 3 As shown in one embodiment of this utility model, a digital direct-to-garment printing device for water-based coatings includes a connector 1, an auxiliary connecting pipe 2, a solenoid valve 3, and a built-in flow disruptor 7. The built-in flow disruptor 7 is installed in the internal cavities of both the inlet pipe 101 and the inlet branch pipe 102 of the connector 1. The conical head 703 at one end of the built-in flow disruptor 7 faces the direction of liquid inflow, thereby disrupting the flow of the water-based coating and liquid water entering the connector 1, causing them to flow in a spiral motion. This allows them to mix thoroughly when they flow together. Furthermore, an auxiliary connecting pipe 2 connected to the liquid inlet branch pipe 102 is equipped with a solenoid valve 3, which facilitates flexible adjustment of the liquid water input and improves ease of use. In addition, the built-in flow deflector 7 is composed of multiple spiral guide plates 701 arranged in a ring array. The embedded ring 702 at one end of the spiral guide plate 701 is fixedly embedded in the pipe wall at the corresponding position inside the connector 1 to ensure stable installation. At the same time, it effectively deflects the flowing liquid, thereby facilitating the direct and thorough mixing of subsequent liquids and ensuring stable printing and spraying.

[0021] like Figure 1 and Figure 2 As shown, in some embodiments, the inlet pipe 101 of the connector 1 is provided with a first quick-connect fitting 4, which facilitates the quick connection of the water-based paint delivery pipe to the connector 1, enabling quick assembly and disassembly between the two and improving ease of use. The outlet pipe 103 of the connector 1 is provided with a second quick-connect fitting 5, which facilitates the quick connection of the input pipe of the digital printing machine direct-to-garment nozzle to the connector 1, enabling quick assembly and disassembly between the two and improving ease of use. This ensures a stable delivery of diluted paint solution to the printing machine nozzle, thereby ensuring smooth printing.

[0022] One end of the auxiliary connecting pipe 2 is fixedly connected to the end of the liquid inlet branch pipe 102, and the other end of the auxiliary connecting pipe 2 is equipped with a third quick connector 6, which facilitates the quick connection of the liquid water conveying pipe to the auxiliary connecting pipe 2, enabling quick assembly and disassembly between the two and improving the ease of use.

[0023] The liquid inlet branch pipe 102 and the auxiliary connecting pipe 2 have the same inner diameter. The ends of the liquid inlet branch pipe 102 and the auxiliary connecting pipe 2 are heat-fused together to facilitate a stable connection between the two, thereby achieving a stable supply of liquid water to dilute the water-based coating and ensure smooth printing and spraying.

[0024] like Figure 2 and Figure 3 As shown, in some embodiments, the embedded ring 702 of the built-in flow disruptor 7 is fixedly embedded in the pipe wall at corresponding positions inside the liquid inlet pipe 101 and the liquid inlet branch pipe 102. The outer wall of the embedded ring 702 is fitted with an anti-slip bushing to facilitate the stable installation of the built-in flow disruptor 7 into the connector 1, ensuring stable use and turbulence of the flowing liquid, which facilitates the thorough mixing of the two liquids. The end of the tapered head 703 of the built-in flow disruptor 7 is a spherical arc surface, which facilitates the diversion of the liquid inside the pipe, allowing it to enter each flow disruptor channel evenly. The flow disruptor channel is composed of two adjacent spiral guide plates 701 and the pipe wall, which effectively turbulent the flowing liquid. At the same time, the spiral guide plates 701 can also be rotatably connected to the embedded ring 702 according to actual usage requirements. When the liquid flows through, it can circulate around the liquid and rotate itself under the drive of the liquid, improving the efficiency of the circulation.

[0025] In use, connect the water-based paint conveying pipe to the first quick-connect connector 4 at the end of the liquid inlet pipe 101, connect the liquid water conveying pipe to the third quick-connect connector 6 at the end of the auxiliary connecting pipe 2, and connect the input pipe of the digital printing machine direct-jet nozzle to the second quick-connect connector 5 at the end of the liquid outlet pipe 103 to complete the connection of the entire conveying pipe.

[0026] Water-based paint enters through inlet pipe 101, and liquid water enters through inlet branch pipe 102. When passing through the internal built-in baffle 7, the water-based paint and liquid water flow in a spiral shape under the action of spiral guide plate 701. Then, they flow together in the cavity inside connector 1. Under the action of spiral flow, the two collide and mix together, achieving full mixing. Then, they enter the input pipe of the direct-to-garment nozzle of the digital printing machine through outlet pipe 103, and finally are sprayed out from the nozzle to complete the printing operation.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
