Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to an automatic rotary feeding mechanism for a screen printing machine. Background Technology

[0002] A screen printing machine, also known as a screen printing machine, is a specialized piece of equipment based on screen printing technology. It works by fixing a pre-made graphic template on the machine and using components such as squeegees to evenly spread ink or paint across the screen, allowing the ink to pass through the graphic area on the screen and be printed onto the surface of the substrate, thereby achieving batch copying of graphics or printing of patterns.

[0003] Existing screen printing machines typically automate the ink scraping action through mechanical structures, but manual assistance is still required for loading and unloading. This can lead to operator fatigue after long hours of work, reducing the quality of subsequent production. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic rotary feeding mechanism for screen printing machines, which aims to improve the problem that existing screen printing machines usually automate the ink scraping action through mechanical structures, but still require manual assistance for feeding and unloading, which leads to fatigue after long-term work and reduces the quality of subsequent production.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automatic rotary feeding mechanism for a screen printing machine includes a fixed frame, a servo motor inside the fixed frame, a placement platform fixedly connected to the upper surface of the fixed frame, a rotating shaft connected to the output end of the servo motor, the outer wall of the rotating shaft rotatably connected to the inside of the placement platform, a vent block fixedly connected to the outer wall of the rotating shaft, a support plate fixedly connected to the lower surface of the vent block, a cylinder on the upper surface of the support plate, a connecting frame connected to the output end of the cylinder, a suction cup on the outer wall of the connecting frame, an air guide hole I inside the suction cup, an air guide hole II on the outer wall of the cylinder, and a limit plate on the upper surface of the placement platform.

[0007] The above technical solution involves controlling the cylinder's operation via an external controller, which further brings the suction cup into contact with the printed material. The negative pressure generated by the suction cup holds the printed material in place. Then, a servo motor is activated to drive the rotating shaft, which in turn drives the ventilation block and support plate to rotate. When the support plate rotates, it causes the cylinder, suction cup, and printed material to rotate synchronously. This achieves automatic suction of the printed material while the servo motor drives the rotating shaft to automatically feed the printed material into the printing table, realizing automatic rotational feeding and avoiding the decline in printing efficiency caused by traditional manual operation for a long time.

[0008] Preferably, the upper surface of the ventilation block is provided with a wiring plate, the outer wall of the wiring plate is fixedly connected to a support block, and the interior of the support block is provided with a fixing component.

[0009] Preferably, the fixing component includes a flip plate, the interior of which is rotatably connected to the outer wall of the first support block, the outer wall of which is fitted with a second support block, the interior of the second support block having a threaded rod, the outer wall of which is threaded with a bolt, and the lower surface of the second support block being fixedly connected to the upper surface of the vent block.

[0010] Preferably, the fixing component further includes a first connecting block, a second connecting block slidably connected to the outer wall of the first connecting block, a housing fixedly connected to the outer wall of the second connecting block, a limit post slidably connected inside the housing, the outer wall of the limit post slidably connected inside the first connecting block and the second connecting block, and a spring provided on the outer wall of the limit post, the spring being disposed inside the housing.

[0011] Preferably, the interior of the outer casing has a groove.

[0012] Preferably, the connecting block one and the connecting block two have holes inside, and the size of the holes is adapted to the limiting post.

[0014] Preferably, the spring is made of a nickel alloy.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, through the cooperation between the servo motor, rotating shaft, air block, support plate, cylinder, connecting frame and suction cup, the printed matter is simultaneously adsorbed and rotated for feeding, thus avoiding fatigue caused by long-term manual operation and reducing the quality of subsequent production.

[0017] 2. In this utility model, by rotating the flip plate to make it fit with the second support block, and then moving the threaded rod to pass through the second support block and fixing the threaded rod with bolts, the flip plate is limited, and the cable board is installed and fixed, ensuring that the air duct is arranged in an orderly manner and improving the simplicity of the working environment.

[0027] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Example 1:

[0029] Reference Figures 1-3An embodiment of this utility model provides an automatic rotary feeding mechanism for a screen printing machine, including a fixed frame 1, a servo motor 2 inside the fixed frame 1, a placement platform 3 fixedly connected to the upper surface of the fixed frame 1, a rotating shaft 4 connected to the output end of the servo motor 2, the outer wall of the rotating shaft 4 rotatably connected to the inside of the placement platform 3, a ventilation block 5 fixedly connected to the outer wall of the rotating shaft 4, a support plate 6 fixedly connected to the lower surface of the ventilation block 5, a cylinder 7 provided on the upper surface of the support plate 6, a connecting frame 8 connected to the output end of the cylinder 7, a suction cup 9 provided on the outer wall of the connecting frame 8, an air guide hole 10 opened inside the suction cup 9, an air guide hole 11 provided on the outer wall of the cylinder 7, and a limit plate 12 provided on the upper surface of the placement platform 3.

[0030] Specifically, the ventilation block 5 has through holes inside. The air guide hole 10 inside the suction cup 9 and the air guide hole 11 on the outer wall of the cylinder 7 are connected to the through holes inside the ventilation block 5 through air guide pipes. First, the cylinder 7 is controlled by an external controller to operate, which further brings the suction cup 9 into contact with the printed matter. The suction cup 9 generates negative pressure to further suck up the printed matter. Then, the servo motor 2 is turned on. When the servo motor 2 is running, the output end of the servo motor 2 and the fixing action of the rotating shaft 4 will drive the rotating shaft 4 to rotate, which will further drive the ventilation block 5 to rotate. When the ventilation block 5 rotates, it will drive the support plate 6 to rotate. When the support plate 6 rotates, the fixing action of the support plate 6 and the cylinder 7 will drive the cylinder 7 to rotate, which will further drive the suction cup 9 and the printed matter to rotate. Thus, while automatically sucking up the printed matter, the servo motor 2 drives the rotating shaft 4 to rotate, which automatically puts the printed matter into the printing table, realizing automatic rotational feeding of the printed matter and greatly improving printing efficiency.

[0031] Example 2:

[0032] Reference Figure 3 and Figure 4 Based on the above embodiments, this embodiment is used to solve the problem of quickly installing the cable board 13 and ensuring the orderly arrangement of the air ducts, and is achieved through the following solution.

[0033] A cable tray 13 is provided on the upper surface of the vent block 5. A support block 14 is fixedly connected to the outer wall of the cable tray 13. A fixing component 15 is provided inside the support block 14. The fixing component 15 includes a flip plate 151. The interior of the flip plate 151 is rotatably connected to the outer wall of the support block 14. A second support block 152 is attached to the outer wall of the flip plate 151. A threaded rod 153 is provided inside the support block 152. A bolt 154 is threadedly connected to the outer wall of the threaded rod 153. The lower surface of the second support block 152 is fixedly connected to the upper surface of the vent block 5.

[0034] Specifically, by rotating the flip plate 151 to fit against the outer wall of the second support block 152, the threaded rod 153 is inserted into the interior of the second support block 152 and fixed with bolts 154, thereby limiting the position of the flip plate 151. The cable board 13 is quickly installed and fixed by the fixing component 15, thereby achieving the orderly arrangement of the air guide pipes connecting the first air guide hole 10, the second air guide hole 11 and the through holes set inside the air block 5, thus improving the cleanliness of the working environment.

[0035] Reference Figures 5-7 The fixing component 15 also includes a connecting block 155, a connecting block 156 slidably connected to the outer wall of the connecting block 155, a housing 157 fixedly connected to the outer wall of the connecting block 156, a limiting post 158 ​​slidably connected inside the housing 157, the outer wall of the limiting post 158 ​​slidably connected inside the connecting block 155 and the connecting block 156, a spring 159 provided on the outer wall of the limiting post 158, the spring 159 being located inside the housing 157; a groove 16 is provided inside the housing 157; holes are provided inside the connecting block 155 and the connecting block 156, the size of which is adapted to the limiting post 158; the outer wall of the connecting block 155 is fixedly connected to the outer wall of the cable tray 13, and the lower surface of the connecting block 156 is fixedly connected to the upper surface of the vent block 5; the spring 159 is made of nickel alloy.

[0036] Specifically, firstly, the sliding limit post 158 ​​slides inside the outer casing 157. When the limit post 158 ​​slides inside the outer casing 157, it compresses the spring 159. Since the spring 159 is made of nickel alloy, the toughness and fatigue resistance of the nickel alloy itself ensure that the spring 159 can maintain good elastic potential energy after long-term use. When the limit post 158 ​​slides to the appropriate position, the limit post 158 ​​is rotated to fix it inside the outer casing 157. Then, the ribbon cable board 13 is moved to drive the connecting block 155 to slide inside the connecting block 2 156. When the connecting block 155 slides to the appropriate position inside the connecting block 2 156, the limit post 158 ​​is rotated in the opposite direction. At this time, the spring 159 will release its own elastic force and push the limit post 158 ​​into the interior of the connecting block 155 and the connecting block 2 156, thereby achieving the effect of quick installation and fixation of the ribbon cable board 13.

[0037] Working principle: When it is necessary to load printed materials, the cylinder 7 is first started by the external controller, which further pushes the connecting frame 8 and the suction cup 9 to move downward, so that the suction cup 9 comes into contact with the printed materials. The air guide hole 10 inside the suction cup 9 is connected to the air guide hole 11 and the through hole inside the air block 5, which further generates negative pressure to adsorb the printed materials. Then, the servo motor 2 is started to drive the rotating shaft 4 to rotate. When the rotating shaft 4 rotates, it will drive the air block 5 to rotate, which will further drive the support plate 6 to rotate. When the support plate 6 rotates, it will drive the cylinder 7 to rotate synchronously, thereby driving the suction cup 9 and the printed materials to rotate to the designated position, thus achieving automatic adsorption and rotation loading of printed materials, which greatly improves the production efficiency.

[0038] When installing the ribbon cable board 13, first rotate the flip plate 151 to make it rotate on the outer wall of the support block 14. When the flip plate 151 flips and fits against the support block 152, the flip plate 151 is limited and fixed by the threaded rod 153 and the bolt 154, further fixing the ribbon cable board 13. Alternatively, the sliding limit post 158 ​​can be used to slide inside the outer shell 157, and while sliding, it cooperates with the outer shell 157 to compress the spring 159. When the limit post 158 ​​slides to the appropriate position, rotate the limit post 158 ​​to... It is fixed inside the outer shell 157 by the groove 16. Then, the moving cable plate 13 drives the connecting block 155 to slide inside the connecting block 2 156. Then, the limiting post 158 ​​is rotated in the opposite direction. At this time, the spring 159 will release its own elasticity and spring into the interior of the connecting block 155 and the connecting block 2 156, thereby limiting and fixing the connecting block 155 and the connecting block 2 156, and further limiting and fixing the cable plate 13. This achieves the effect of quick installation of the cable plate 13, making the arrangement of the air duct more orderly and improving the maintenance efficiency of the equipment.
