[0014] In an embodiment thereof, when the external force applied to the wire mesh is greater than the frictional force between the outer ring of the one-way bearing and the inner wall of the first through hole, the outer ring of the one-way bearing rotates relative to the inner wall of the first through hole in the second direction, so that the wire mesh moves towards the direction close to the supporting assembly.

[0043] Such as Figure 1 And Figure 2As shown, in some embodiments, a screen printing machine includes a supporting component 100, a screen 110, a fixing component 200, and a rotating component 300. The supporting component 100 is disposed opposite to the screen 110. The supporting component 100 is used to support the workpiece to be processed. The screen 110 is used to process the workpiece to be processed. One end of the fixing component 200 is connected to the screen 110 and is used to fix the screen 110. The other end of the fixing component 200 is rotatably connected to the rotating component 300. The rotating component 300 is used to suspend the screen 110 relative to the supporting component 100 at any angle.

[0044] During operation, the rotating component 300 drives the fixing component 200 to rotate, so that the fixing component 200 drives the screen 110 to rotate. After the screen 110 rotates to a preset angle, the rotating component 300 suspends the screen 110 relative to the supporting component 100, thereby realizing the suspension of the screen 110 at any angle. By suspending the screen 110 at any angle, the screen 110 can be attached to or separated from the workpiece to be processed. When the screen 110 is attached to the workpiece to be processed, the screen 110 processes the workpiece to be processed.

[0045] It can be understood that a printing plate is provided on the screen 110, and a pattern or text to be transferred is engraved on the printing plate by laser engraving, so that the pattern or text on the printing plate is a hollowed-out part, and the mesh holes of the hollowed-out part can penetrate the ink. The user adds ink to the screen 110 and scrapes the ink, and the ink is transferred to the workpiece through the mesh holes of the hollowed-out part, thereby completing the screen printing process of the workpiece. After the processing of the workpiece to be processed is completed, the screen 110 is separated from the workpiece to be processed. After the screen 110 is suspended, there is no need for the operator to manually fix the screen 110, which makes the screen printing process more convenient and improves the screen printing efficiency.

[0046] As Figure 1 shown, in some embodiments, a screen printing machine includes a workbench 400. The supporting component 100 can be disposed on the workbench 400. The supporting component 100 is used to support the workpiece to be processed. The workpiece to be processed can be placed on the supporting component 100.

[0047] In some embodiments, the supporting component 100 can be disposed on the workbench 400 in the horizontal direction, so that the workpiece to be processed can be placed on the supporting component 100 in the horizontal direction, facilitating the processing of the workpiece to be processed.

[0048] In some embodiments, the supporting component 100 can be a plate-like structure, facilitating the placement of the workpiece to be processed on the supporting component 100.

[0049] In some embodiments, the supporting component 100 can be a square structure to adapt to the square workpiece to be processed.

[0050] In some embodiments, the supporting component 100 is disposed opposite to the wire mesh 110. The supporting component 100 and the wire mesh 110 may be disposed opposite to each other in the vertical direction. The wire mesh 110 can move towards the supporting component 100 and process the workpiece to be processed on the supporting component 100. After the processing is completed, the wire mesh 110 is separated from the workpiece to be processed and can move away from the supporting component 100.

[0051] As Figure 2 and Figure 5 shown, in some embodiments, the fixing component 200 can be a frame clamp block. When the wire mesh 110 is attached to the workpiece to be processed, the fixing component 200 is disposed in the horizontal direction. The fixing component 200 can be a strip-shaped structure. A fixing groove 240 is formed in the length direction of the fixing component 200. The wire mesh 110 is fixed in the fixing groove 240.

[0052] In some embodiments, one end of the fixing component 200 is detachably connected to the wire mesh 110, facilitating the replacement of different wire meshes 110.

[0053] As Figure 4 shown, in some embodiments, the rotating component 300 includes a base 310. The base 310 is provided with a first through hole 311. The first through hole 311 is formed along the length direction of the fixing component 200. The first through hole 311 is formed in the horizontal direction. The first through hole 311 can be a cylindrical through hole.

[0054] As Figure 6 shown, in some embodiments, the rotating component 300 includes a one-way bearing 320. The one-way bearing 320 has an outer ring 321. The one-way bearing 320 is disposed in the first through hole 311, and the outer ring 321 of the one-way bearing 320 contacts the inner wall of the first through hole 311, so that the outer ring 321 of the one-way bearing 320 has a frictional force with the inner wall of the first through hole 311. When the external force applied to the outer ring 321 of the one-way bearing 320 is less than the frictional force, the outer ring 321 of the one-way bearing 320 is fixed to the hole wall of the first through hole 311. When the external force applied to the outer ring 321 of the one-way bearing 320 is greater than the frictional force, the outer ring 321 of the one-way bearing 320 can rotate relative to the hole wall of the first through hole 311.

[0055] The one-way bearing 320 also has an inner ring 322. The inner ring 322 of the one-way bearing 320 can rotate unidirectionally relative to the outer ring 321 of the one-way bearing 320 in a first direction. The inner ring 322 of the one-way bearing 320 can only rotate in a single direction. It can be understood that the first direction is the direction in which the wire mesh 110 moves away from the supporting component 100.

[0056] As Figure 4As shown, the rotating assembly 300 includes a damping rotating shaft 330. The damping rotating shaft 330 has a first shaft portion 331. The first shaft portion 331 is connected to the fixing assembly 200. When the fixing assembly 200 drives the wire mesh 110 to rotate in the first direction, the fixing assembly 200 rotates synchronously with the first shaft portion 331 of the damping rotating shaft 330.

[0057] In some embodiments, a first mounting hole 210 is formed on one side of the fixing assembly 200. The first shaft portion 331 of the damping rotating shaft 330 can extend into the first mounting hole 210 so that one end of the damping rotating shaft 330 is connected to the fixing assembly 200.

[0058] In some embodiments, the first shaft portion 331 of the damping rotating shaft 330 has a strip-shaped structure. The first mounting hole 210 is a strip-shaped hole. When the strip-shaped first shaft portion 331 extends into the strip-shaped first mounting hole 210, relative rotation between the first shaft portion 331 of the damping rotating shaft 330 and the hole wall of the first mounting hole 210 can be avoided, ensuring that the first shaft portion 331 of the damping rotating shaft 330 and the fixing assembly 200 can rotate synchronously.

[0059] In some embodiments, the damping rotating shaft 330 has a second shaft portion 332. The second shaft portion 332 and the first shaft portion 331 are integrally formed. The second shaft portion 332 is connected to the inner ring 322 of the one-way bearing 320. When the fixing assembly 200 drives the wire mesh 110 to rotate in the first direction, the fixing assembly 200 drives the first shaft portion 331 of the damping rotating shaft 330 to rotate in the first direction. The first shaft portion 331 and the second shaft portion 332 of the damping rotating shaft 330 rotate synchronously. The second shaft portion 332 of the damping rotating shaft 330 drives the inner ring 322 of the one-way bearing 320 to rotate relative to the outer ring 321 in the first direction. Specifically, the second shaft portion 332 of the damping rotating shaft 330 can have a cylindrical structure to fit the inner ring 322 of the one-way bearing 320.

[0060] As Figure 2 and Figure 3 shown, in some embodiments, multiple rotating assemblies 300 can be provided. The multiple rotating assemblies 300 are spaced apart on the fixing assembly 200, and can flip or hover the fixing assembly 200 more stably, thereby flipping or hovering the wire mesh 110 more stably. Specifically, two rotating assemblies 300 can be provided. The two rotating assemblies 300 can be oppositely arranged at both ends of the fixing assembly 200.

[0061] In some embodiments, the frictional force between the outer ring 321 of the one-way bearing 320 and the inner wall of the first through hole 311 is equal to the gravity of the wire mesh 110 to limit the rotation of the outer ring 321 of the one-way bearing 320 relative to the inner wall of the first through hole 311 in the second direction, where the second direction is the opposite rotational direction to the first direction. Specifically, the first direction refers to the direction in which the wire mesh 110 rotates away from the workpiece of the supporting assembly 100. The second direction refers to the direction in which the wire mesh 110 approaches the supporting assembly 100 and can rotate while conforming to the workpiece.

[0062] When the external force applied to the wire mesh 110 is greater than the frictional force between the outer ring 321 of the one-way bearing 320 and the inner wall of the first through hole 311, the outer ring 321 of the one-way bearing 320 rotates relative to the inner wall of the first through hole 311 in the second direction, causing the wire mesh 110 to move in the direction closer to the supporting assembly 100.

[0063] It should be noted that during the processing of the workpiece by the wire mesh 110, both the fixing assembly 200 and the wire mesh 110 are arranged in the horizontal direction. After the wire mesh 110 finishes processing the workpiece to be processed, an external force is applied to drive the fixing assembly 200 to rotate in the first direction to a preset angle. The fixing assembly 200 drives the damping rotating shaft 330 to rotate in the first direction. The damping rotating shaft 330 drives the inner ring 322 of the one-way bearing 320 to rotate relative to the outer ring 321 in the first direction.

[0064] It can be understood that since the one-way bearing 320 can only rotate in the first direction, the operator can rotate the wire mesh in the first direction to move the wire mesh 110 away from the supporting assembly 100. When the wire mesh 110 reaches the angle desired by the operator, the force applied to rotate the wire mesh in the first direction is removed. At this time, since the frictional force between the outer ring 321 of the one-way bearing 320 and the inner wall of the first through hole 311 is equal to the gravity of the wire mesh 110, the wire mesh is in a hovering state, so that the wire mesh 110 can achieve hovering at any angle. Since the frictional force between the outer ring 321 of the one-way bearing 320 and the inner wall of the first through hole 311 is equal to the gravity of the wire mesh 110, the outer ring 321 of the one-way bearing 320 cannot rotate relative to the inner wall of the first through hole 311 in the second direction opposite to the first direction. And the inner ring 322 of the one-way bearing 320 can only rotate unidirectionally relative to the outer ring 321 of the one-way bearing 320 in the first direction, so the inner ring 322 of the one-way bearing 320 cannot rotate relative to the outer ring 321 in the second direction either, enabling the fixing assembly 200 to hover on the base 310. That is, the wire mesh 110 hovers on the base 310.

[0065] During the process of the operator flipping the screen mesh 110 in the first direction, the inner ring 322 of the one-way bearing 320 rotates relative to the outer ring 321. The resistance during this process is extremely small, and the screen mesh 110 can be easily flipped. After the screen mesh 110 is flipped to an appropriate angle, since the frictional force between the outer ring 321 of the one-way bearing 320 and the inner wall of the first through hole 311 is equal to the gravity of the screen mesh 110, the screen mesh 110 can hover on the base 310 without operating a locking structure to hover the screen mesh 110, which is convenient to operate and improves the silk printing effect. In addition, this silk printing machine does not need to additionally set a locking structure between the base 310 and the fixing component 200, which can reduce the volume of the silk printing machine and the occupied space of the silk printing machine.

[0066] When the screen mesh 110 hovers on the base 310 and it is necessary to process the workpiece to be processed with the screen mesh 110, when an external force is applied to the fixing component 200 and the screen mesh 110, and the external force received by the screen mesh 110 is greater than the frictional force between the outer ring 321 of the one-way bearing 320 and the inner wall of the first through hole 311, the outer ring 321 of the one-way bearing 320 can rotate relative to the inner wall of the first through hole 311 in the second direction, so that the screen mesh 110 moves in the direction close to the supporting component 100. During the process of the screen mesh 110 approaching the supporting component 100, the operator can directly manually operate the fixing component 200 and the screen mesh 110, without unlocking an additional locking structure, which is convenient to operate and improves the silk printing effect.

[0067] It should be noted that in some other embodiments, the flipping and hovering of the screen mesh 110 can also be realized through a rotating shaft and a counterweight. By adjusting the weight of the counterweight, the weight of the counterweight offsets the self-weights of the fixing component 200 and the screen mesh 110, so as to realize the flipping and hovering of the screen mesh 110.

[0068] As Figure 4 and Figure 7 shown, in some embodiments, the silk printing machine further includes a gasket 500. The gasket 500 is arranged on the damping rotating shaft 330. The gasket 500 is located between the base 310 and the fixing component 200. During the rotation of the fixing component 200, friction will be generated between the fixing component 200 and the base 310, causing wear of the fixing component 200 and the base 310. The gasket 500 can avoid the friction between the fixing component 200 and the base 310, reduce the wear between the two, and thus improve the service life of the silk printing machine. Specifically, the gasket 500 can be a nylon gasket 500.

[0069] As Figure 7 shown, in some embodiments, a second mounting hole 510 is opened in the center of the gasket 500. The damping rotating shaft 330 passes through the second mounting hole 510.

[0070] In some embodiments, one side of the gasket 500 abuts against the side of the first mounting hole 210 of the fixing component 200 facing the base 310. The other side of the gasket 500 abuts against the side of the first through hole 311 of the base 310 facing the first mounting hole 210.

[0071] In some embodiments, the gasket 500 has a circular structure. The circular gasket 500 fits against the edge side wall of the cylindrical first through hole 311.

[0072] As Figures 7 to 9 shown, in some embodiments, the base 310 is provided with a first limiting portion 312 and a second limiting portion 313. The first limiting portion 312 and the second limiting portion 313 are arranged at an angle and are located on the rotation trajectory of the fixing component 200 to limit the rotation range of the fixing component 200 relative to the base 310, thereby limiting the rotation range of the screen 110.

[0073] It should be noted that during the screen printing process, the flipping of the screen 110 is to switch the screen 110 between the fitting state and the disengaged state with the workpiece to be processed. Therefore, the flipping angle of the screen 110 does not need to be too large. When the flipping angle of the screen 110 is too large, the flipping trajectory of the screen 110 will also be too large, easily causing collisions between the screen 110 and other components and damaging the screen 110. By limiting the rotation range of the screen 110 through the first limiting portion 312 and the second limiting portion 313 and reducing the flipping trajectory of the screen printing, the structure of the screen 110 can be protected.

[0074] When the fixing component 200 abuts against the first limiting portion 312, the fixing component 200 is in the state of the minimum flipping angle, as Figure 8 shown in the state. The fixing component 200 and the screen 110 start to flip upward from the first limiting portion 312. When the fixing component 200 and the screen 110 flip by a certain angle, the fixing component 200 abuts against the second limiting portion 313, and the second limiting portion 313 restricts the fixing component 200 and the screen 110 from continuing to flip upward. At this time, the fixing component 200 is in the state of the maximum flipping angle, as Figure 9 shown in the state.

[0075] In some embodiments, the first limiting portion 312 can be a plate-like structure.

[0076] In some embodiments, the angle between the fixing component 200 and the first limiting portion 312 is less than 90°, so that the rotation angle of the screen 110 is limited within an acute angle range. That is, the flipping angle of the fixing component 200 and the screen 110 is less than 90°.

[0077] Specifically, the included angle between the fixing component 200 and the first limiting portion 312 is less than 60°. That is, the flipping angle of the fixing component 200 and the wire mesh 110 is less than 60°. More specifically, the optimal flipping angle of the wire mesh 110 can be 45°.

[0078] As Figure 9 shown, in some embodiments, the fixing component 200 has a first abutting surface 220 and a second abutting surface 230. The first abutting surface 220 and the second abutting surface 230 can be arranged at an included angle. The first abutting surface 220 and the second abutting surface 230 can be perpendicularly arranged. When the fixing component 200 is at the minimum flipping angle, the first abutting surface 220 abuts against the first limiting portion 312. When the fixing component 200 is at the maximum flipping angle, the second abutting surface 230 abuts against the second limiting portion 313.

[0079] The included angle between the fixing component 200 and the first limiting portion 312 described above can specifically be the included angle between the first abutting surface 220 of the fixing component 200 and the upper surface of the first limiting portion 312 when the fixing component 200 is at the maximum flipping angle.

[0080] As Figure 9 shown, in some embodiments, the base 310 further includes an adjusting member 314. The first limiting portion 312 is arranged in the horizontal direction. The adjusting member 314 passes through the first limiting portion 312, and the adjusting member 314 can move up and down relative to the first limiting portion 312. One end of the adjusting member 314 facing the fixing component 200 can abut against the fixing component 200 to adjust the angle of the fixing component 200, and further adjust the flipping angle of the wire mesh 110. Specifically, one end of the adjusting member 314 facing the fixing component 200 can abut against the first abutting surface 220 of the fixing component 200.

[0081] It should be noted that when the upper end surface of the adjusting member 314 is flush with the upper surface of the first limiting portion 312, the fixing component 200 and the wire mesh 110 are in the horizontal direction. When the fixing component 200 and the wire mesh 110 need to be placed at a certain inclination angle, the adjusting member 314 moves upward relative to the first limiting portion 312, and the inclination angle of the fixing component 200 and the wire mesh 110 placed is adjusted according to the distance that the adjusting member 314 moves upward. The longer the distance that the adjusting member 314 moves upward, the larger the inclination angle of the fixing component 200 and the wire mesh 110 placed. The shorter the distance that the adjusting member 314 moves upward, the smaller the inclination angle of the fixing component 200 and the wire mesh 110 placed.

[0082] In some embodiments, a threaded hole is formed in the first limiting portion 312. The adjusting member 314 can be an adjusting screw. By screwing the adjusting screw into the threaded hole, fine adjustment of the angle of the fixing component 200 can be achieved.

[0083] As Figure 4 andFigure 11 As shown, in some embodiments, the rotating assembly 300 further includes a locking member 340. A gap 350 communicating with the first through hole 311 is formed in the base 310. A first connection hole 360 and a second connection hole 370 are formed on both sides of the gap 350. The locking member 340 sequentially passes through the first connection hole 360 and the second connection hole 370, so that the inner wall of the first through hole 311 abuts against the outer ring 321 of the one-way bearing 320, thereby generating a frictional force between the inner wall of the first through hole 311 and the outer ring 321 of the one-way bearing 320. Specifically, the inner diameter of the first through hole 311 may be the same as the outer diameter of the outer ring 321 of the one-way bearing 320.

[0084] It should be noted that a gap 350 is formed in the base 310. The gap 350 can increase the diameter of the first through hole 311, so that the one-way bearing 320 can be installed in the first through hole 311. The locking member 340 is disposed in the first connection hole 360 and the second connection hole 370 to reduce the distance of the gap 350, thereby reducing the diameter of the first through hole 311, so that the inner wall of the first through hole 311 abuts against the outer ring 321 of the one-way bearing 320, thereby generating a frictional force between the inner wall of the first through hole 311 and the outer ring 321 of the one-way bearing 320. When the distance of the gap 350 is smaller, the frictional force between the inner wall of the first through hole 311 and the outer ring 321 of the one-way bearing 320 is greater. When the distance of the gap 350 is larger, the frictional force between the inner wall of the first through hole 311 and the outer ring 321 of the one-way bearing 320 is smaller.

[0085] In this embodiment, by providing the locking member 340, the size of the gap 350 can be adjusted to adjust the inner diameter of the first through hole 311, so that the frictional force between the inner wall of the first through hole 311 and the outer ring 321 of the one-way bearing 320 can be adjusted as needed, realizing the hovering of the wire mesh 110 of different weights, and improving the practicability and versatility of the screen printing machine.

[0086] In some embodiments, the first connection hole 360 and the second connection hole 370 may be threaded holes. The locking member 340 may be a screw. Through the threaded fit of the screw and the threaded hole, the distance of the gap 350 can be stably and finely adjusted.

[0087] In some embodiments, a plurality of locking members 340 may be provided. A plurality of first connection holes 360 and a plurality of second connection holes 370 may be provided. The plurality of locking members 340 are respectively arranged in one-to-one correspondence with the plurality of first connection holes 360 and the plurality of second connection holes 370, and the diameter of the first through hole 311 is reduced from different positions, so that the inner wall of the first through hole 311 abuts more stably against the outer ring 321 of the one-way bearing 320.

[0088] In some embodiments, the gap 350 may be provided at the bottom of the base 310.
