[0004] Therefore, the defects are very obvious, and a solution is urgently needed. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a screen cleaning device for screen printing machines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A screen cleaning device for a screen printing machine includes a moving drive mechanism, a base mounted on the moving end of the moving drive mechanism, a cleaning seat that is lifted and lowered on the base, a lifting drive mechanism mounted on the base and used to drive the cleaning seat to rise and fall, a mounting base mounted on the cleaning seat, a cleaning roller rotatably connected to the top of the mounting base, a guide roller rotatably connected to the bottom of the mounting base and arranged parallel to the cleaning roller, a take-up shaft rotatably connected to the cleaning seat, a take-up drive mechanism mounted on the cleaning seat and used to drive the take-up shaft to rotate, an unwinding shaft rotatably connected to the cleaning seat and arranged parallel to the take-up shaft, and a damper mounted on the cleaning seat. The damping shaft of the damper is coaxially connected to the unwinding shaft. The take-up shaft and the unwinding shaft are located on the same side of the mounting base, and the upper side of the cleaning roller extends beyond the top surface of the mounting base.

[0007] Furthermore, the screen cleaning device for screen printing machines also includes a vision inspection mechanism, which is mounted on the base.

[0014] The beneficial effects of this invention are as follows: In practical applications, the cleaning cloth roll is mounted on the unwinding shaft. The cleaning cloth released from the roll winds around the guide roller and cleaning roller sequentially from bottom to top, and then wraps around the take-up drum of the take-up shaft. When the screen printing machine needs to be cleaned, the lifting drive mechanism drives the cleaning seat to rise, so that the cleaning cloth on the cleaning roller contacts the screen. Then, the moving drive mechanism drives the base and cleaning seat to move back and forth, so that the cleaning cloth on the cleaning roller wipes the screen, thus cleaning it. When the cleaning cloth needs to be replaced, the take-up drive mechanism drives the take-up shaft to rotate at a preset angle. The take-up shaft rotated at the preset angle winds up the cleaning cloth for a preset length, so that the dirty cleaning cloth is wound onto the take-up drum, and the new cleaning cloth is located on the cleaning roller, making it easy for the cleaning cloth to clean the screen again. Throughout the process, the damper provides damping force to the unwinding shaft to ensure that the cleaning cloth is always taut, preventing the cleaning cloth from becoming loose and affecting the cleaning effect on the screen. This utility model has a simple and compact structure, low cost, small size, small space occupation, short winding path of cleaning cloth, smooth movement of cleaning cloth, and facilitates replacement and winding of cleaning cloth roll.

[0018] like Figure 1 and Figure 2 As shown, this utility model provides a screen cleaning device for a screen printing machine, which includes a moving drive mechanism, a base 1 mounted on the moving end of the moving drive mechanism, a cleaning seat 2 lifted and lowered on the base 1, a lifting drive mechanism 3 mounted on the base 1 and used to drive the cleaning seat 2 to rise and fall, a mounting base 4 mounted on the cleaning seat 2, a cleaning roller 5 rotatably connected to the top of the mounting base 4, a guide roller 6 rotatably connected to the bottom of the mounting base 4 and arranged parallel to the cleaning roller 5, and a take-up shaft 7 rotatably connected to the cleaning seat 2. The cleaning seat 2 includes a winding drive mechanism 9 for driving the winding shaft 7 to rotate, an unwinding shaft 8 rotatably connected to the cleaning seat 2 and arranged parallel to the winding shaft 7, and a damper 10 installed on the cleaning seat 2. The damping shaft of the damper 10 is coaxially connected to the unwinding shaft 8. The winding shaft 7 and the unwinding shaft 8 are located on the same side of the mounting base 4, and the upper side of the cleaning roller 5 extends beyond the top surface of the mounting base 4. Specifically, the winding shaft 7 is located above the unwinding shaft 8, between the cleaning roller 5 and the guide roller 6, and the unwinding roller is located below the guide roller 6.

[0019] In practical applications, the cleaning cloth roll is mounted on the unwinding shaft 8. The cleaning cloth released from the roll winds from bottom to top, passing through the guide roller 6 and the cleaning roller 5, before winding onto the take-up drum of the take-up shaft 7. When the screen printing machine needs cleaning, the lifting drive mechanism 3 drives the cleaning seat 2 to rise, allowing the cleaning cloth on the cleaning roller 5 to contact the screen. Then, the moving drive mechanism drives the base 1, along with the cleaning seat 2, to move back and forth, allowing the cleaning cloth on the cleaning roller 5 to wipe the screen, thus cleaning it. When the cleaning cloth needs to be replaced, the take-up drive mechanism 9 drives the take-up shaft 7 to rotate at a preset angle. The take-up shaft 7, rotating at the preset angle, winds up the cleaning cloth for a preset length, so that the dirty cleaning cloth is wound onto the take-up drum. The new cleaning cloth is located on the cleaning roller 5, making it easy for the cleaning cloth to clean the screen again. Throughout the process, the damper 10 provides damping force to the unwinding shaft 8 to ensure that the cleaning cloth remains taut, preventing it from becoming loose and affecting the cleaning effect on the screen. This invention features a simple and compact structure, low cost, small size, and minimal space occupation. The cleaning cloth has a short winding path, moves smoothly, and facilitates the replacement and winding of the cleaning cloth roll.

[0020] In this embodiment, the screen cleaning device for the screen printing machine further includes a vision inspection mechanism 11, which is disposed on the base 1. Before or during the cleaning process, the vision inspection mechanism 11 can visually inspect and locate the markings on the screen, which helps the cleaning cloth to accurately clean the screen.

[0021] In this embodiment, the take-up shaft 7 and / or the unwind shaft 8 are fitted with a plurality of spring plungers 12, the ball bearings of which can extend beyond the peripheral wall of the take-up shaft 7 or the unwind shaft 8. In practical applications, the ball bearings of the spring plungers 12 elastically clamp the inner wall of the take-up drum onto the take-up shaft 7, facilitating the disassembly and replacement of the take-up drum; the ball bearings of the spring plungers 12 elastically clamp the inner wall of the cleaning cloth roll onto the unwind shaft 8, facilitating the replacement of the cleaning cloth roll.

[0022] In another embodiment, the take-up shaft 7 and / or the unwind shaft 8 are pneumatic shafts. In practical applications, the pneumatic shafts expand or contract to clamp or release the take-up drum or cleaning cloth roll, facilitating the replacement or disassembly of the take-up drum or cleaning cloth roll.

[0023] In this embodiment, the base 1 is equipped with a first fine-tuning platform 13, and the cleaning seat 2 is mounted on the first fine-tuning platform 13. In practical applications, the first fine-tuning platform 13 can fine-tune the position of the cleaning seat 2 to fine-tune the position of the cleaning roller 5, thereby fine-tuning the position of the cleaning cloth.

[0024] In this embodiment, the cleaning seat 2 is equipped with a second fine-tuning platform 14, and the visual inspection mechanism 11 is mounted on the second fine-tuning platform 14. In practical applications, the second fine-tuning platform 14 can fine-tune the visual inspection position of the visual inspection mechanism 11. Specifically, the visual inspection mechanism 11 can be a CCD vision mechanism.

[0025] In this embodiment, a limiting ring 15 is protruding from the outer peripheral wall of the inner end of the take-up shaft 7 and / or the unwind shaft 8. When installing the take-up drum or cleaning cloth roll, when the limiting ring 15 abuts against one end face of the take-up drum or cleaning cloth roll, it proves that the take-up drum or cleaning cloth roll is installed in place.

[0026] In this embodiment, the cleaning seat 2 is equipped with a sensor for detecting the cleaning cloth. The sensor detects the cleaning cloth; when the sensor detects the cleaning cloth, it indicates that there is still cleaning cloth on the cleaning cloth roll; when the sensor does not detect the cleaning cloth, it indicates that there is no cleaning cloth on the cleaning cloth roll, thus reminding the operator to replace the cleaning cloth roll.

[0027] In this embodiment, the cleaning seat 2 is equipped with a meter counter, which is used to calculate the length of the cleaning cloth. The meter counter is used to calculate the length of the cleaning cloth, which helps the operator to determine the remaining length of the cleaning cloth roll and facilitates timely replacement of the cleaning cloth roll.

[0028] All technical features in this embodiment can be freely combined according to actual needs.

[0029] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
