[0034] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0035] The glass silk-screen printing equipment disclosed in the embodiment of the present application includes an ink storage component 10, a flow control component 20 and a silk-screen printing component. The ink storage component 10 includes an ink storage structure 11 and an ink outlet hose 12. The first end of the ink outlet hose 12 is connected to the ink storage structure 11. The flow control component 20 includes a first mounting seat 21 and a clamping structure 22. The first mounting seat 21 is connected to the ink storage structure 11. The clamping structure 22 is connected to the first mounting seat 21. The clamping structure 22 clamps the ink outlet hose 12. The silk-screen printing component and the ink outlet hose 12 are arranged correspondingly.

[0036] Applying the technical solution of the present embodiment, ink contained within the ink reservoir 11 enters the ink outlet hose 12. The clamping structure 22 deforms the ink outlet hose 12, changing its cross-sectional shape and the ink flow rate. When the ink outlet hose 12 is fully clamped, the ink cannot flow. Therefore, precisely controlling the clamping force of the clamping structure 22 allows for precise control of the ink flow rate. The technical solution of this embodiment effectively addresses the prior art issue of poor print quality caused by excessive or insufficient ink in glass screen printing.

[0037] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6As shown, in the technical solution of this embodiment, the clamping structure 22 includes a horizontal driving unit 221, a first clamping unit 222, and a second clamping unit 223. The first clamping unit 222 is connected to the output end of the horizontal driving unit 221, and the second clamping unit 223 is connected to the first mounting base 21. The ink outlet hose 12 is partially located between the first clamping unit 222 and the second clamping unit 223. The first clamping unit 222 has a clamping state close to the second clamping unit 223 and a ready-to-clamp state away from the second clamping unit 223. Under the action of the horizontal driving unit 221, the first clamping unit 222 moves horizontally in the direction of the [circle around the ink tube], causing the distance between the first clamping unit 222 and the second clamping unit 223 to change. This causes the ink outlet hose 12 to deform, thereby changing the ink outlet speed from the ink outlet hose 12. When the distance between the first clamping unit 222 and the second clamping unit 223 is minimized, the ink outlet hose 12 can no longer discharge ink, thereby controlling the amount of ink output. The first clamping portion 222 and the second clamping portion 223 are used to clamp the ink outlet hose 12 to change the cross-sectional shape of the ink outlet hose 12, thereby controlling the ink outlet amount and ink outlet speed. This method has a simple structure, is easy to operate, and saves manpower.

[0038] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, in the technical solution of this embodiment, the first mounting seat 21 includes a fixing portion 211. The fixing portion 211 is connected to the second clamping portion 223 and is located on the side of the second clamping portion 223 away from the ink reservoir assembly 10. The second end of the ink outlet hose 12 extends through the fixing portion 211. The fixing portion 211 is provided with a fixing hole, through which the ink outlet hose 12 passes. The fixing hole is also provided with an annular groove circumferentially disposed. The inner wall surface of the annular groove is provided with threads for connecting to the hose fixing joint. The threads of the annular groove mate with the external threads of the hose fixing structure. During installation, the second end of the ink outlet hose 12 is first inserted through the fixing hole. The hose fixing joint is then fitted over the second end of the ink outlet hose 12. The inner diameter of the hose fixing joint is smaller than the outer diameter of the ink outlet hose 12, forming an interference fit. The hose fixing joint then mates with the threads of the annular groove, and the second end of the ink outlet hose 12 is now fixed. The setting of the fixing portion 211 prevents the position of the second end of the ink outlet hose 12 from being offset when the ink outlet hose 12 is subjected to external force from the clamping structure 22, resulting in the ink failing to drip to the expected position, causing ink waste and affecting the screen printing effect.

[0039] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6As shown, in the technical solution of this embodiment, the flow control assembly 20 also includes a negative pressure structure, which is connected to the horizontal drive unit 221 and is positioned toward the second end of the ink outlet hose 12. The negative pressure structure includes a first negative pressure line, a second negative pressure line, an air pump, and a recovery tank. The first end of the first negative pressure line is positioned toward the second end of the ink outlet hose 12. After the ink outlet hose 12 is fully clamped by the clamping structure 22, the first negative pressure line provides negative pressure, which absorbs the ink remaining in the ink outlet hose 12, preventing further dripping of the ink, resulting in an actual ink volume greater than expected, affecting the silk screen printing effect. The second end of the first negative pressure line is connected to the recovery tank. The recovery tank is topped with a sealing cap. The first negative pressure line is installed on the sealing cap. The distance between the second end of the first negative pressure line and the bottom of the recovery tank is less than one-tenth of the height of the recovery tank. Excess ink falls directly to the bottom of the recovery tank due to the negative pressure. The first end of the second negative pressure line is connected to the recovery tank, which is installed on the sealing cap. The distance between the first end of the second negative pressure line and the bottom of the recovery tank is greater than nine-tenths of the recovery tank's height. The second end of the second negative pressure line is connected to the air pump. The recovery tank is made of a transparent material. When the ink level is close to the first end of the second negative pressure line, the negative pressure suction is stopped, the recovery tank is opened, and the ink is recovered. This structural arrangement not only recovers excess ink and avoids waste, but also effectively prevents ink from being sucked into the negative pressure pump, causing failure of pump components.

[0040] like Figures 1 to 6 As shown, in the technical solution of this embodiment, the ink storage structure 11 includes a second mounting seat 111 and an ink storage tank 112, the second mounting seat 111 is connected to the first mounting seat 21, the second mounting seat 111 has a through hole, the ink storage tank 112 is arranged in the through hole, the ink storage tank 112 includes a connecting section 1121, a limiting section 1122 and a guide section 1123, the connecting section 1121, the limiting section 1122 and the guide section 1123 are connected in sequence, the diameter of the limiting section 1122 is larger than the diameter of the through hole, the diameter of the guide section 1123 gradually decreases in the direction from approaching to away from the limiting section 1122, and the first end of the ink outlet hose 12 is connected to the end of the guide section 1123 away from the limiting section 1122. The setting of the limiting section 1122 allows the ink storage tank 112 to be fixed in the through hole under the action of its own gravity, and the setting of the guide section 1123 allows the ink to flow to the bottom of the guide section 1123 under the action of gravity and enter the ink outlet hose 12, thereby preventing a large amount of ink from remaining at the bottom of the ink storage structure 11.

[0041] like Figures 1 to 7As shown, in the technical solution of this embodiment, the ink storage assembly 10 further includes a sealing structure 13, which is connected to the end of the connecting section 1121 away from the limiting section 1122. The sealing structure 13 seals the ink storage tank 112 to prevent the ink from being exposed to air for a long time and thus deteriorating. The sealing structure 13 is provided with an air inlet, through which dry gas is introduced to increase the air pressure within the ink storage tank 112, allowing the ink to flow out of the ink outlet hose 12. The use of air to control the ink outflow is more stable and prevents the low air pressure inside the ink storage tank 112 from preventing the ink from flowing out.

[0042] like Figures 1 to 7 As shown, in the technical solution of this embodiment, the sealing structure 13 includes a blocking portion 131 and a sealing portion 132. The vertical projection of the connecting section 1121 is located within the vertical projection of the blocking portion 131. The sealing portion 132 is connected to the blocking portion 131. The outer diameter of the sealing portion 132 is smaller than the inner diameter of the connecting section 1121. The sealing portion 132 is covered with a rubber sealing ring. The blocking portion 131 seals the entire ink tank 112 to prevent dust and other particles from entering the ink tank 112. The sealing portion 132 seals the ink tank 112, ensuring its tightness and preventing gas from escaping when gas is introduced, which could prevent the ink from flowing out properly.

[0043] like Figures 1 to 6 As shown, in the technical solution of this embodiment, the glass screen printing device further includes a stirring assembly 30, which is partially disposed in the ink storage structure 11. The stirring assembly 30 stirs the ink in the ink storage tank 112 to keep the ink in a flowing state and avoid stratification of the ink caused by long-term static state.

[0044] like Figures 1 to 6 As shown, in the technical solution of this embodiment, the stirring assembly 30 includes a stirring structure and a motor 31. The stirring structure includes a rotating shaft and paddles. The paddles are connected to the rotating shaft and located within the ink storage structure 11. The rotating shaft is connected to the output shaft of the motor 31. The paddles are provided in multiple groups, each group including multiple paddles evenly distributed along the axis of the rotating shaft. The multiple groups of paddles are arranged at intervals along the axis of the rotating shaft. The rotation of the motor drives the rotating shaft, which in turn rotates the multiple groups of paddles, driving the flow of ink within the entire ink storage tank 112 and preventing stratification.

[0045] like Figures 1 to 6As shown, in the technical solution of this embodiment, the ink storage assembly 10 also includes a horizontal drive structure and a vertical drive structure. The second mounting seat 111 is connected to the horizontal drive structure, which in turn is connected to the vertical drive structure. The horizontal and vertical drive structures work together to move the ink tank 112 mounted on the second mounting seat 111 to the appropriate position, and the clamping structure 22 controls the ink outlet hose 12 for ink refilling. The arrangement of the horizontal and vertical drive structures increases the range of motion of the ink tank 112, making it suitable for refilling ink for screen printing of different product models.

[0046] In summary, the glass screen printing device provided herein utilizes a drive mechanism: After the horizontal and vertical drive structures drive the ink storage structure 11 to a designated position, the cylinder (horizontal drive unit 221) controls the lower ink port to begin adding ink. Implementation: The servo motor (motor 31) is mounted and connected to the motor mounting bracket, which is then installed above the upper cap and connected to the ink tank (ink storage tank 112). The cylinder mounting bracket (first mounting bracket 21) is connected to the ink tank and the cylinder. The air pipe (negative pressure structure) connected to the cylinder can be connected to a vacuum pressure gauge for timely adjustment of the air pressure. The device features an easily removable and replaceable structure, allowing for quick replacement of empty ink barrels (ink storage tank 112), saving time. The amount of ink added can be precisely controlled and easily adjusted. The simple structure and limited number of components allow for quick replacement of faulty parts and low procurement costs. The solution is highly implementable and replicable, enabling rapid deployment of production lines. The cylinder is connected to a negative pressure gauge and a negative pressure pump, which can promptly suck ink from the ink outlet (ink outlet hose 12) without causing environmental pollution.
