Technical Field
[0001] This application relates to the technical field of screen printing machines, and in particular to an air-cushion device for screen printing machines. Background Technology
[0002] During the operation of a screen printing machine, the positional accuracy and angle adjustment flexibility of the squeegee structure directly affect the printing quality. Traditional screen printing machine squeegee devices often suffer from fixed structures and inconvenient adjustments. Their positional movement typically relies on a single drive method, making precise multi-directional adjustments difficult. Furthermore, squeegee angle adjustment is cumbersome, and the squeegee itself is not securely fixed, easily shifting during printing, leading to defects such as printed patterns deviations and omissions, thus impacting production efficiency and product quality. In addition, the connection structure between the squeegee and the pressure block in traditional devices is complex, making disassembly and maintenance inconvenient and increasing equipment operating costs. Therefore, to solve the above problems, this application provides an air-cushion device for screen printing machines. Utility Model Content

The cylinder is located at the top of the guide rail, the sliding plate connected to the ink scraping structure is located on the inner side of the guide rail, and the slider is located on one side of the guide rail via the support arm.
[0006] The ink scraping structure includes a pressure block, grippers, a bracket, an angle adjustment knob, a fixing plate, a printing scraper, a return ink scraper, and a fastening knob. The grippers are provided at both ends of the outer side of the pressure block, and the bracket is provided at the top of the pressure block. The bracket is rotatably connected to the rotating block at the bottom of the slide plate through the angle adjustment knob. The fixing plate is pressed against the bottom of the pressure block. The printing scraper and the return ink scraper are both located at the bottom of the fixing plate. The fastening knob is threaded to the top of the grippers.
[0007] Preferably, there are two cylinders, and the two cylinders are mounted side by side on the top of the guide rail.
[0008] Preferably, the slide plate has multiple through holes for mounting and connecting.
[0009] Preferably, there are two grippers, which respectively clamp the two ends of the pressure block.
[0010] Preferably, the printing squeegee and the ink return squeegee are arranged side by side at the bottom of the fixed plate.
[0011] Preferably, the angle adjustment knob can adjust the rotation angle between the bracket and the rotating block, thereby adjusting the tilt angle of the pressure block.
[0012] Preferably, when the fastening knob is tightened, the gripper exerts a fastening force on the pressure block, preventing the pressure block from shifting position during operation.
[0013] In summary, this application includes the following beneficial technical effects:
[0014] Through the coordinated action of the cylinder, guide rail, slider, and support arm in the moving assembly, the doctor blade structure achieves flexible movement in both the longitudinal and lateral directions, significantly improving the accuracy and efficiency of position adjustment. The coordinated design of the angle adjustment knob and rotating block in the doctor blade structure allows for quick adjustment of the tilt angle of the pressure block and doctor blade, adapting to different printing conditions. Simultaneously, the combination of the gripper and fastening knob provides a stable clamping effect on the pressure block, effectively preventing positional shifts during operation and ensuring consistent printing quality. The overall device is compact and easy to adjust, simplifying the operation process, improving the adaptability and production efficiency of the screen printing machine, and reducing maintenance costs.

[0019] The following is in conjunction with the appendix Figure 1 - Figure 3 This application will be described in further detail.
[0020] Example 1:
[0021] An air-cushion device for a screen printing machine, as described in the following figure Figure 1 - Figure 3 It includes a moving component for moving the position of the scraper structure and a scraper structure for performing the scraping action.
[0022] The moving assembly includes a cylinder 3, a guide rail 4, a sliding plate 5, a support arm 2, and a slider 1. A cylinder 3 is mounted at the top of the guide rail 4. Preferably, two cylinders 3 are mounted side-by-side at the top of the guide rail 4 to provide a more stable driving force. A sliding plate 5, connected to the ink scraping structure, is located on the inner side of the guide rail 4. The sliding plate 5 has multiple through holes for mounting and connection, facilitating fixed connections with other components. A slider 1 is mounted on one side of the guide rail 4 via the support arm 2. The slider 1 can slide along the outer rail, cooperating with the support arm 2 to achieve lateral movement of the entire device.
[0023] The squeegee structure includes a pressure block 6, grippers 7, a support 61, an angle adjustment knob 62, a fixing plate 91, a printing squeegee 9, a return ink squeegee 10, and a fastening knob 8. Grippers 7 are provided at both ends of the outer side of the pressure block 6; there are two grippers 7, which respectively press the two ends of the pressure block 6 into position. A support 61 is located at the top of the pressure block 6. The support 61 is rotatably connected to a rotating block 51 at the bottom of the slide plate 5 via the angle adjustment knob 62. The angle adjustment knob 62 can adjust the rotation angle between the support 61 and the rotating block 51, thereby adjusting the tilt angle of the pressure block 6 to adapt to different printing needs.
[0024] A fixing plate 91 is pressed against the bottom of the pressure block 6. The printing squeegee 9 and the ink return squeegee 10 are both located at the bottom of the fixing plate 91, arranged side-by-side to perform printing and ink return actions respectively. A fastening knob 8 is threaded onto the top of the gripper 7. When the fastening knob 8 is tightened, the gripper 7 applies a clamping force to the pressure block 6, preventing positional displacement during operation and ensuring printing accuracy.
[0025] The working process of this device is as follows: the cylinder 3 drives the slide plate 5 to move along the guide rail 4, thereby adjusting the longitudinal position of the squeegee structure; simultaneously, the slider 1 slides along the external slide rail, cooperating with the support arm 2 to adjust the lateral position of the entire device, thus achieving the overall positional movement of the squeegee structure. During the printing process, the tilt angle of the pressure block 6 can be adjusted by the angle adjustment knob 62 to achieve the optimal working angle for the printing squeegee 9 and the return ink squeegee 10; by tightening the fastening knob 8, the clamping jaws 7 firmly clamp the pressure block 6, ensuring structural stability during operation.
