DETAILED DESCRIPTION OF THE EMBODIMENTS

[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0040] Refer to Figure 1 、 Figure 3 and Figure 4, An embodiment provided by the present utility model: A jig for the machining of a large swing of a printing press, including a bottom plate 1. At the four corners of the top wall of the bottom plate 1, corner chutes 3 are fixedly connected. The corner chutes 3 play a role in guiding and limiting. At the top ends of multiple corner chutes 3, limiting plates 4 are fixedly connected. The limiting plates 4 impose certain restrictions on the adjustment process. Adjusting lead screws 5 penetrate through the top walls of multiple limiting plates 4. The adjusting lead screws 5 are used to adjust the height of the adjusting plate 7. At the bottom ends of multiple adjusting lead screws 5, rotating shafts 6 are rotatably connected. The rotating shafts 6 enable the adjusting lead screws 5 to rotate smoothly. Multiple rotating shafts 6 are rotatably connected around the top wall of the bottom plate 1. The outer walls of multiple adjusting lead screws 5 are threadedly connected with an adjusting plate 7. Components such as a housing 8, an ink storage tank 9, and a printing plate 14 are installed on the adjusting plate 7. A housing 8 is fixedly connected to the top wall of the adjusting plate 7. The housing 8 provides protection for components such as a printing roller 10. An ink storage tank 9 is fixedly connected to the rear side of the top wall of the adjusting plate 7. The ink storage tank 9 is used to store the ink required for printing. Multiple printing rollers 10 are rotatably connected to the inner wall of the housing 8. The printing rollers 10 are the core components for printing. At the left ends of multiple printing rollers 10, driven gears 11 are fixedly connected. A rotating motor 12 is fixedly connected to the left side of the top wall of the housing 8. The rotating motor 12 provides power for the rotation of the printing rollers 10. The output end of the rotating motor 12 is fixedly connected to a driving gear 13. The driving gear 13 is meshed with multiple driven gears 11 to drive the printing rollers 10 to rotate. A printing plate 14 is fixedly connected to the front side of the top wall of the adjusting plate 7. The printing plate 14 cooperates with the printing rollers 10 to complete the printing process. A printing ink filling mechanism 2 is arranged on the inner bottom wall of the ink storage tank 9. The printing ink filling mechanism 2 is used to fill the ink storage tank 9 with ink;

[0041] Specifically, the bottom plate 1 serves as the basic support component of the entire fixture, providing a stable installation platform for other parts. The four corner chutes 3 are fixed at the four corners of the top wall of the bottom plate 1, playing a role of guiding and limiting. The limiting plate 4 is installed at the top end of the corner chute 3 to impose certain restrictions on the adjustment process. The adjustment screw rod 5 passes through the limiting plate 4, and its bottom end is rotatably connected to the surrounding of the top wall of the bottom plate 1 through a rotating shaft 6. When the height or position needs to be adjusted, the adjustment screw rod 5 is rotated. Since the adjustment screw rod 5 is threadedly connected to the adjustment plate 7, the rotation of the adjustment screw rod 5 will drive the adjustment plate 7 to move up and down under the guidance of the corner chute 3, thereby realizing the adjustment of height. The adjustment plate 7 is provided with a housing 8, an ink storage tank 9, and a printing plate 14. The ink storage tank 9 is used to store the ink required for printing. The multiple printing rollers 10 rotatably connected to the inner wall of the housing 8 are the core components for printing. When the rotating motor 12 is started, the driving gear 13 at its output end rotates. Since the driving gear 13 is meshed with the driven gears 11 at the left ends of the multiple printing rollers 10, the rotation of the driving gear 13 will drive the driven gears 11 to rotate, and then the printing rollers 10 will rotate in the housing 8. After the printing rollers 10 dip the ink from the ink storage tank 9, they transfer the ink to the printing plate 14 during the rotation process. Through cooperation with the printing plate 14, the ink is printed on the workpiece to be processed. In actual use, if it is found that the fixture is tilted, the height of the adjustment plate 7 can be adjusted by rotating the adjustment screw rod 5, thereby finely adjusting the levelness of the fixture. When the fixture is in a completely horizontal state, the contact between the printing rollers 10 and the printing plate 14 will be more uniform, and the transfer of the ink will be more stable, making the processing more accurate.

[0042] Refer to Figure 3 and Figure 5 Moreover, the low-level detector 201 is fixedly connected to the inner bottom wall of the ink storage tank 9, which can detect the low-level state of the ink in the ink storage tank 9 and issue a reminder. The upper middle part of the front side of the inner wall of the ink storage tank 9 is fixedly connected with a high-level detector 202, which can detect the high-level state of the ink in the ink storage tank 9 to prevent overflow. The rear side of the inner bottom wall of the ink storage tank 9 is fixedly connected with a filling pipe 203, and the filling pipe 203 is used as the filling channel for the ink. The top end of the filling pipe 203 is fixedly connected with a conical hopper 204, and the conical hopper 204 facilitates the smooth flow of the ink into the filling pipe 203. A plurality of liquid outlet holes 205 are equidistantly arranged at the bottom end of the outer wall of the filling pipe 203, and the plurality of liquid outlet holes 205 enable the ink to flow into the ink storage tank 9 more evenly. The top end of the conical hopper 204 is fixedly installed with a sealing cover 206, and the sealing cover 206 can maintain the sealing performance of the ink storage tank 9 when the ink is not being filled.

[0043] Specifically, during the printing process, the low-level detector 201 is fixedly connected to the inner bottom wall of the ink storage tank 9, which can monitor the liquid level height of the ink. When the liquid level of the ink drops to a certain extent, the low-level detector 201 will send a signal to remind the staff that the ink stock is insufficient. The high-level detector 202 in the upper middle part of the front side of the inner wall of the ink storage tank 9 is used to prevent overfilling of the ink. When the ink liquid level rises close to the top of the ink storage tank 9, the high-level detector 202 will sense it and send a signal to avoid waste and pollution caused by ink overflow. The filling pipe 203 on the rear side of the inner bottom wall of the ink storage tank 9 is the channel for ink filling. When ink needs to be filled, the staff opens the sealing cover 206 and pours the ink into the conical hopper 204. The design of the conical hopper 204 facilitates the smooth flow of the ink into the filling pipe 203. The multiple liquid outlet holes 205 equidistantly arranged at the bottom end of the outer wall of the filling pipe 203 enable the ink to flow into the ink storage tank 9 more evenly, avoiding the ink concentrating in one place and causing too high local concentration or poor flow. Such a design ensures the stable supply of ink in the ink storage tank 9, enables the printing process to proceed continuously and efficiently, and at the same time, through the coordinated action of the low-level detector 201 and the high-level detector 202, the filling amount of the ink can be accurately controlled, improving the printing quality and work efficiency.

[0044] Refer to Figure 1 and Figure 2 On the right side of the top wall of the outer shell 8, a control console 15 is fixedly connected. The control console 15 serves as the control center for operating the entire jig. On the top wall of the control console 15, a plurality of control buttons 16 are fixedly connected. The control buttons 16 can realize various operation controls of the printing machine. The top ends of the plurality of adjusting screw rods 5 are all fixedly connected with rotating ring buckles 17. The rotating ring buckles 17 facilitate the staff to rotate the adjusting screw rods 5. The outer walls of the plurality of rotating ring buckles 17 all adopt a frosted process. The frosted process increases the friction force, making the rotation easier and more stable. On the front end of the right side of the top wall of the outer shell 8, a tachometer 18 is fixedly connected. The tachometer 18 can display the output rotation speed of the rotating motor 12 in real time. The tachometer 18 is electrically connected to the rotating motor 12, which is convenient for the staff to adjust the motor speed according to the rotation speed to ensure the printing quality and efficiency.

[0045] Specifically, the control console 15 is the control center. The control buttons 16 can adjust the rotating motor 12 and control the rotation of the printing roller 10 to meet different printing requirements. The rotating ring buckles 17 facilitate the staff to rotate the adjusting screw rods 5. The outer walls of the rotating ring buckles 17 adopt a frosted process, which increases the friction force and makes the rotation easier and more stable, facilitating the precise adjustment of the height of the adjusting plate 7. The tachometer 18 is electrically connected to the rotating motor 12 and can display the output rotation speed of the rotating motor 12 in real time, so as to adjust the motor speed according to the actual situation to ensure the printing quality and efficiency.

[0046] Refer to Figure 1 and Figure 2, foot pads 19 are fixedly connected to the four corners of the bottom wall of the bottom plate 1. The foot pads 19 play a role in stable support. The outer shapes of the multiple foot pads 19 are all conical structures with a smaller top and a larger bottom. The conical structure increases stability. Horizontal frames 20 are fixedly connected to the left and right sides of the top wall of the adjusting plate 7. The horizontal frames 20 provide installation positions for the spirit levels 21. A plurality of spirit levels 21 are fixedly connected to the inner walls of the two horizontal frames 20. The spirit levels 21 are used to detect the levelness of the adjusting plate 7. The outer walls of the multiple corner chutes 3 are all designed to be smooth. The smooth design prevents the staff from being scratched. The multiple corner chutes 3 are all designed symmetrically. The symmetrical design ensures the stability of the movement of the adjusting plate 7;

[0047] Specifically, the foot pads 19 are located at the four corners of the bottom wall of the bottom plate 1. The conical structure with a smaller top and a larger bottom makes it have good stability, which can effectively prevent the printing machine from shaking or displacing during operation, and ensure the printing accuracy and stability. The horizontal frames 20 provide installation positions for the spirit levels 21. The spirit levels 21 can help the staff detect the levelness of the adjusting plate 7 and the entire printing machine, so as to timely find out whether the printing machine is in a horizontal state. The outer wall of the corner chute 3 is designed to be smooth, which can prevent the staff from being scratched during operation and improve safety. The symmetrical design ensures the stability and balance of the adjusting plate 7 during the up and down movement, ensuring that all components of the printing machine can work in coordination and improving the printing quality.

[0048] Working principle: The bottom plate 1 serves as the basic support component of the entire jig, providing a stable installation platform for other parts. The four corner chutes 3 are fixed at the four corners of the top wall of the bottom plate 1, playing a role of guiding and limiting. The limiting plate 4 is installed at the top of the corner chute 3 to impose certain restrictions on the adjustment process. The adjusting screw rod 5 passes through the limiting plate 4, and its bottom end is rotationally connected to the top wall around the bottom plate 1 through a rotating shaft 6. When the height or position needs to be adjusted, the adjusting screw rod 5 is rotated. Since the adjusting screw rod 5 is threadedly connected to the adjusting plate 7, the rotation of the adjusting screw rod 5 will drive the adjusting plate 7 to move up and down under the guidance of the corner chute 3, thereby realizing the adjustment of the height. The adjusting plate 7 is equipped with a housing 8, an ink storage tank 9, and a printing plate 14. The ink storage tank 9 is used to store the ink required for printing. The multiple printing rollers 10 rotatably connected to the inner wall of the housing 8 are the core components for printing. When the rotating motor 12 is started, the driving gear 13 at its output end rotates. Since the driving gear 13 is meshed with the driven gears 11 at the left ends of the multiple printing rollers 10, the rotation of the driving gear 13 will drive the driven gears 11 to rotate, and then the printing rollers 10 will rotate in the housing 8. After the printing rollers 10 dip the ink from the ink storage tank 9, they transfer the ink to the printing plate 14 during the rotation process, and through the cooperation with the printing plate 14, print the ink on the workpiece to be processed;

[0049] Moreover, during the printing process, the low-level detector 201 is fixedly connected to the inner bottom wall of the ink storage tank 9, which can monitor the liquid level height of the ink. When the liquid level of the ink drops to a certain extent, the low-level detector 201 will send a signal to remind the staff that the ink stock is insufficient. The high-level detector 202 in the upper middle part of the front side of the inner wall of the ink storage tank 9 is used to prevent overfilling of the ink. When the ink liquid level rises close to the top of the ink storage tank 9, the high-level detector 202 will sense and send a signal to avoid waste and pollution caused by ink overflow. The filling pipe 203 on the rear side of the inner bottom wall of the ink storage tank 9 is the channel for ink filling. When ink needs to be filled, the staff opens the sealing cover 206 and pours the ink into the conical hopper 204. The design of the conical hopper 204 facilitates the smooth flow of the ink into the filling pipe 203. A plurality of liquid outlet holes 205 are equidistantly arranged at the bottom end of the outer wall of the filling pipe 203, enabling the ink to flow into the ink storage tank 9 more evenly, avoiding the ink concentrating in one place and causing too high local concentration or poor flow. Such a design ensures the stable supply of ink in the ink storage tank 9.
