[0003] For the above-mentioned related technology, the inventor believes that the following defects exist: the existing silk screen printing machine is mostly placed on the workbench by the staff. Then, the staff starts the squeegee on the silk screen printing machine to print the workpiece. In this process, the staff needs to take down the workpiece and put in a new one to perform the next printing, thereby reducing the work efficiency of the staff. INVENTION CONTENTS
[0004] In order to solve the above problems, the utility model provides a silk screen printing machine.
[0005] The above technical purpose of the utility model is realized by the following technical scheme: a silk screen printing machine, comprising a base, the upper surface of the base is fixedly provided with a mounting seat, the upper surface of the mounting seat is provided with a rotating groove, the rotating groove is rotatably provided with a rotating block, the upper surface of the rotating block is arrayed with a plurality of workbenches, the upper surface of the base is fixedly provided with a support frame with an L-shaped cross section, the bottom surface of the support frame in the horizontal direction is fixedly provided with an internally hollow mounting box, the sidewall of the mounting box is fixedly provided with an air cylinder, the bottom surface of the mounting box is provided with a squeegee, the air cylinder is used to drive the squeegee, and the mounting seat is provided with a driving assembly for driving the intermittent rotation of the rotating block.
[0006] By adopting the above technical scheme, when the staff needs to scrape the ink on the screen plate, the staff needs to put the screen plate into the workbench. In this process, the staff needs to start the driving assembly, and then the driving assembly drives the rotating block to rotate. Since the driving assembly drives the intermittent movement of the rotating block, the workbench is rotated to the lower side of the mounting box under the action of the rotating block. At this time, the staff needs to start the air cylinder, and then the piston rod of the air cylinder is extended, so that the squeegee moves under the action of the piston rod of the air cylinder, and then the squeegee scrapes the ink on the surface of the screen plate in the workbench. Subsequently, when the scraping is completed, the rotating block is rotated again under the action of the driving assembly, and then another workbench is rotated to the lower side of the mounting box. In this process, when the squeegee is working, the staff can put the screen plate into the workbench, and when the rotation is completed, the printing can be performed, thereby improving the work efficiency of the staff.
[0007] Further, the driving assembly comprises a connecting rod fixedly arranged on the bottom surface of the rotating block, a rotating plate fixedly arranged on the bottom surface of the connecting rod, a motor fixedly arranged on the inner bottom wall of the rotating groove, a driving disc fixedly arranged on the end of the output shaft of the motor, and an eccentric member fixedly arranged on the upper surface of the driving disc, the driving disc and the eccentric member are eccentrically designed, the upper surface of the rotating plate is arrayed with a through groove, and the eccentric member is in sliding connection with the through groove.
[0008] By adopting the above technical scheme, when the staff needs to rotate the rotating block, the staff needs to start the motor, and then the output shaft of the motor rotates, so that the driving disc rotates under the action of the output shaft of the motor, and then the eccentric member rotates with the driving disc, so that the eccentric member rotates into the through groove, and then the rotating plate rotates under the action of the eccentric member, so that the connecting rod and the rotating block rotate under the action of the rotating plate. In this process, when the rotating disc rotates by 90 degrees, the eccentric member and the through groove are separated from each other, so that the rotating plate stops rotating. When the eccentric member rotates into the through groove again, the rotating plate rotates again. In the time when the eccentric member and the through groove are separated from each other, the ink on the surface of the screen plate is scraped off. After scraping is completed, the rotating block rotates under the action of the rotating plate, thereby improving the work efficiency of the staff.

[0010] By adopting the above technical scheme, when the circular plate rotates under the action of the driving disc, the circular grooves and the circular plate rotate relatively. In this process, the circular block limits the rotating plate and the driving disc, thereby reducing the probability of shaking of the driving disc during rotation, thereby improving the stability of the device.
[0011] Further, an arc groove is formed in the outer wall of the circular plate, and the arc groove is in rotational connection with the rotating plate.
[0012] By adopting the above technical scheme, when the rotating plate rotates, the arc groove is opposite to the rotating plate at this time, thereby reducing the probability of collision between the rotating plate and the circular plate during rotation, thereby improving the stability of the device.
[0013] Further, an annular groove is formed in the inner wall of the rotating groove, an annular block is rotatably arranged in the annular groove, and the annular block and the rotating block are fixedly connected with each other.
[0014] By adopting the above technical scheme, when the rotating block rotates, the annular block rotates under the action of the rotating block. In this process, the annular block limits the rotating block, thereby reducing the probability of sliding of the rotating block, thereby reducing the probability of movement of the connecting rod and the rotating plate, and thereby improving the stability of the device.
[0015] Further, the support frame comprises a sliding sleeve fixed on the upper surface of the base, an L-shaped sliding rod slidingly arranged in the sliding sleeve, and a fixing bolt threaded through the side wall of the sliding sleeve, and the L-shaped sliding rod is fixed with the mounting box.
[0016] By adopting the above technical scheme, the height of the mounting box can be adjusted by the L-shaped sliding rod, and the height of the oil scraping knife can be adjusted, thereby improving the practicability of the device.
[0017] Further, a plurality of heat dissipation holes are formed through the inner wall of the rotating groove.
[0018] By adopting the above technical scheme, the heat dissipation holes reduce the probability of damage of the motor due to overheating during long-time operation, thereby prolonging the service life of the device.

In this process, the worker needs to start the driving assembly, and then the driving assembly drives the rotating block to rotate. Since the driving assembly drives the rotating block to move intermittently, the workbench is rotated to the position directly below the mounting box under the action of the rotating block. At this time, the worker needs to start the cylinder, and then the piston rod of the cylinder is extended, so that the oil scraping plate moves under the action of the piston rod of the cylinder, and then the oil scraping plate scrapes the ink on the surface of the screen in the workbench. Subsequently, when the scraping is completed, the rotating block is rotated again under the action of the driving assembly, and then the other workbench is rotated to the position below the mounting box. In this process, when the oil scraping plate is working, the worker can put the screen into the workbench, and when the rotation is completed, the printing can be performed, thereby improving the work efficiency of the worker.
[0021] 2. In the present application, when the worker needs to rotate the rotating block, the worker needs to start the motor, and then the output shaft of the motor is rotated, so that the driving disc is rotated under the action of the output shaft of the motor, and then the eccentric member is rotated with the driving disc, so that the eccentric member is rotated into the through groove, and then the rotating plate is rotated under the action of the eccentric member, so that the connecting rod and the rotating block are rotated under the action of the rotating plate.

When the eccentric member is rotated into the through groove again, the rotating plate rotates again. In the time when the eccentric member and the through groove are separated from each other, the ink on the surface of the screen is scraped. When the scraping is completed, the rotating block is rotated under the action of the rotating plate, thereby improving the work efficiency of the worker.

The workbench 13 is arranged on the upper surface of the rotating block 12 in an array, and the support frame 14 is fixedly arranged on the upper surface of the base 1. The mounting box 15 is in the shape of a hollow rectangular block, and the mounting box 15 is fixedly arranged on the horizontal bottom surface of the support frame 14. The cylinder 16 is fixedly arranged on the side wall of the mounting box 15, and the axis of the piston rod of the cylinder 16 is horizontal. The oil scraping plate 17 is arranged on the bottom surface of the mounting box 15, and the cylinder 16 is used for driving the oil scraping plate 17.
[0029] When the staff needs to scrape the ink on the screen plate, the staff needs to put the screen plate into the workbench 13, in the process, the staff needs to start the driving assembly 2, so that the driving assembly 2 drives the rotating block 12 to rotate, because the driving assembly 2 drives the rotating block 12 to move intermittently, so that the workbench 13 is rotated to the position directly below the mounting box 15 under the action of the rotating block 12. At this time, the staff needs to start the cylinder 16, so that the piston rod of the cylinder 16 is extended, so that the oil scraping plate 17 moves under the action of the piston rod of the cylinder 16, so that the oil scraping plate 17 scrapes the ink on the surface of the screen plate in the workbench 13. Then, when the scraping is completed, the rotating block 12 is rotated again under the action of the driving assembly 2, so that another workbench 13 is rotated to the position below the mounting box 15, in the process, when the oil scraping plate 17 is working, the staff can put the screen plate into the workbench 13.
[0030] The driving assembly 2 is arranged in the mounting seat 11 and is used for driving the rotating block 12 to rotate intermittently, the driving assembly 2 comprises a connecting rod 21, a rotating plate 22, a motor 23, a driving disc 24 and an eccentric part 25.

The annular block 51 is fixedly connected with the rotating block 12.
[0036] When the rotating block 12 rotates, the annular block 51 rotates under the action of the rotating block 12. In this process, the annular block 51 limits the rotating block 12, thereby reducing the probability of sliding of the rotating block 12, thereby reducing the probability of movement of the connecting rod 21 and the rotating plate 22, thereby improving the stability of the device.

[0038] The staff can adjust the height of the mounting box 15 through the L-shaped sliding rod 142, and then adjust the height of the oil scraping knife, so as to improve the practicability of the device.
[0039] In order to prolong the service life of the device, a plurality of heat dissipation holes 6 are arranged through the inner wall of the rotating groove 18. The heat dissipation holes 6 reduce the probability of damage of the motor 23 due to overheating during long-time work, thereby prolonging the service life of the device.
[0040] The working principle of the screen printing machine in the embodiment is as follows: when the staff needs to scrape the ink on the screen plate, the staff needs to put the screen plate into the workbench 13. In this process, the staff needs to start the driving assembly 2, so that the driving assembly 2 drives the rotating block 12 to rotate. Since the driving assembly 2 drives the rotating block 12 to move intermittently, the workbench 13 is rotated to the position directly below the mounting box 15 under the action of the rotating block 12. At this time, the staff needs to start the air cylinder 16, so that the piston rod of the air cylinder 16 extends, so that the oil scraping plate 17 moves under the action of the piston rod of the air cylinder 16, and then the oil scraping plate 17 scrapes the ink on the surface of the screen plate in the workbench 13. Subsequently, when the scraping is completed, the rotating block 12 is rotated again under the action of the driving assembly 2, so that the other workbench 13 is rotated to the position below the mounting box 15. In this process, when the oil scraping plate 17 is working, the staff can put the screen plate into the workbench 13.
