[0025] 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.

[0026] This utility model provides, for example Figure 1-5 The screen printing machine anti-drip ink device shown includes a fixing block 1 and two fixing seats 8 installed on the lower side of the fixing block 1;

[0027] The lower outer walls of both fixed seats 8 are fixedly connected with fixing strips 7;

[0028] The lower outer walls of the two fixing strips 7 are respectively fixedly connected to fixing brackets 9 and clamping plates 6;

[0029] A guide plate 10 is fixedly connected to the lower outer wall of the fixed support 9, and a guide plate 11 is fixedly connected to the lower outer wall of the guide plate 10. First, according to the structural characteristics and design requirements of the screen printing machine, the installation position of the fixed block 1 on the printing machine is determined. The printing squeegee is first installed inside the clamping plate 6 and used in the subsequent printing process. After printing is completed, the squeegee is removed, and the fixed support 9 is installed on the lower side of the fixed strip 7 to block the ink outlet, thereby preventing ink from dripping.

[0030] A fixed plate 12 is fixedly connected to the lower outer wall of the guide plate 11. Sponges 14 are provided inside the upper outer wall of the fixed plate 12 near the left and right sides to absorb ink. Multiple openings b19 are provided inside the lower outer wall of the fixed support 9 to guide the ink flow. When ink droplets fall on the fixed support 9, the ink will first come into contact with the surface of the fixed support 9. Then, under the action of gravity, the ink will flow downward through the openings b19 on the lower outer wall of the fixed support 9 and fall on the guide plate 10. The ink will slide down along the inclined surface of the guide plate 10 and transfer to the guide plate 11. The guide plate 11 will further guide the ink to the fixed plate 12 and finally be absorbed by the sponges 14 on the fixed plate 12, completing the ink droplet recovery process.

[0031] like Figure 3As shown, the upper outer wall of the fixing plate 12 is provided with an upward-opening groove 13 near the left and right sides to restrict the placement of the sponge 14. Each of the two sponges 14 is provided with a handle 15 to remove the sponge 14 from the groove 13 under the action of external force.

[0032] When it is necessary to clean or replace the sponge 14, the operator can easily remove the sponge 14 from the groove 13 by holding the handle 15 and applying external force, and recover the ink absorbed by the sponge 14.

[0033] like Figure 4 As shown, the lower outer wall of the fixing plate 12 and inside the groove 13 are provided with openings a16. The two openings a16 are screwed with sealing plugs 17. The two sealing plugs 17 and the fixing plate 12 are provided with anti-leakage rings 18.

[0034] When the ink absorbed by the sponge 14 reaches a certain amount, it will become saturated. At this time, some ink may seep out from the bottom of the sponge 14. The opening a16 can guide this seeping ink downwards, preventing ink from accumulating in the groove 13 and further ensuring the smoothness of ink recycling. The sealing plug 17 is tightened in the opening a16 to prevent ink from flowing out of the opening a16 at will. It also works with the leak-proof ring 18 to enhance the sealing effect and ensure that the ink is mainly absorbed by the sponge 14.

[0035] like Figure 1 As shown, guide rods 3 that pass through the fixing block 1 are fixedly connected to the upper outer walls of the two fixing seats 8 and near the front and rear sides respectively. A guide device 2 is fixedly connected to the upper outer wall of the fixing block 1 to connect with the external driving device. A driver 5 is fixedly connected to the front outer wall of the two fixing seats 8 to control the tilt angle of the fixing bar 7. An adjustment knob 4 is provided on the upper outer wall of the two drivers 5 and the fixing seats 8.

[0036] The guide rod 3 serves as a guide, ensuring stable and accurate vertical movement of the fixed base 8. The guide device 2 is used to connect with an external drive device. The external drive device can control the vertical movement of the fixed block 1 and the entire anti-drip ink device through the guide device 2. Driven by the driver 5, the angle of the fixed strip 7 can be changed, thereby adjusting the tilt angle of the fixed support 9 and the clamp 6. The operator can precisely control the action of the driver 5 by manually rotating the adjustment knob 4 to achieve fine-tuning of the tilt angle of the fixed strip 7 to meet different printing needs.

[0037] The implementation principle of this embodiment is as follows: First, based on the structural characteristics and design requirements of the screen printing machine, the installation position of the fixing block 1 on the printing machine is determined. The printing squeegee is first installed inside the clamping plate 6 for use in the subsequent printing process. After printing is completed, the squeegee is removed, and the fixing bracket 9 is installed on the lower side of the fixing strip 7 to block the ink outlet, thereby preventing ink dripping. If ink drips onto the fixing bracket 9, the ink will first come into contact with the surface of the fixing bracket 9. Subsequently, under the action of gravity, the ink flows downward through the opening b19 on the lower outer wall of the fixing bracket 9 and falls onto the guide plate 10. The ink slides downward along the inclined surface of the guide plate 10 and is transferred to the guide plate 11. The guide plate 11 further guides the ink to the fixing plate 12, and finally it is absorbed by the sponge 14 on the fixing plate 12, completing the ink dripping recovery process.

[0038] 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.
