Description

Technical Field

[0001] This application relates to the technical field of printing press frames, and particularly to a printing press frame. Background Art

[0002] A machine for printing words and images. Modern printing presses generally consist of mechanisms such as plate loading, inking, impression, and paper feeding (including folding). Its working principle is as follows: First, the words and images to be printed are made into printing plates and installed on the printing press. Then, ink is applied to the areas with words and images on the printing plate manually or by the printing press, and then directly or indirectly transferred to paper or other printing substrates (such as textiles, metal plates, plastics, leather, wood boards, glass, and ceramics), thereby replicating the same printed matter as the printing plate.

[0003] For example, the Chinese utility model patent with the publication number CN220562411U discloses an adjustable-height printing press frame, including a fixed platform. On both sides of the outer surface of the lower end of the fixed platform, feet are fixedly installed. A printing platform is arranged at the upper end of the fixed platform. A moving group is arranged on the outer surface of the lower end of the printing platform. Moving frames are arranged on the outer surfaces of the front and rear ends of the moving group. A printing box is arranged on the outer surface of the upper end of the moving frame. A control panel is arranged on one outer surface of the printing platform. Baffles are fixedly installed on both sides of the outer surface of the lower end of the printing platform. The disclosed adjustable-height printing press frame can conveniently adjust the height of the printing platform, facilitating the use by operators of different heights, improving applicability, facilitating the limited lifting of the printing platform, and being able to adjust the height of the printing box, facilitating the adjustment of the height of the printing box according to the thickness of the paper or other printing substrates to be printed, bringing a better application prospect.

[0004] Regarding the above related technologies, the inventor believes that when adjusting the height of the existing printing press frame, it is generally achieved by the way of pushing with a cylinder. However, when the cylinder is powered off, the frame may automatically move the cylinder piston due to its weight, resulting in the automatic dropping of the frame, which poses a certain safety hazard.

Detailed implementation manners

[0024] The following will Figures 1-5 make a further detailed description of this application.

[0025] An embodiment of this application discloses a printing press frame. Referring to Figures 1-5 , a printing press frame includes a frame 1, a printing press body 2, a driving mechanism, and a plurality of hollow support seats 3. A support plate 4 is slidably installed inside each of the plurality of support seats 3. A connecting plate 5 is fixedly connected to one side of two corresponding support seats 3. An installation plate 8 is fixedly connected between the two connecting plates 5. Mounting seats 7 are fixedly connected to the middle parts of the upper surfaces of the two connecting plates 5. Two parallel connecting shafts 13 are rotatably installed between the two mounting seats 7. The two ends of the connecting shaft 13 respectively penetrate through the side walls of the two mounting seats 7 and are sleeved with connecting bars 6. A through groove 18 is formed at the bottom of the support plate 4. A connecting column 12 is arranged inside the through groove 18. One end of the connecting bar 6 is movably arranged inside the through groove 18, and a moving groove 11 is formed at this end of the connecting bar 6. The connecting column 12 is movably arranged inside the moving groove 11;

[0026] The frame 1 is located above the plurality of support plates 4, and the tops of the plurality of support plates 4 are fixedly connected to the lower surface of the frame 1;

[0027] The printing machine body 2 is arranged on the upper surface of the frame 1, and the printing machine body 2 is used to print the substrate. The printing machine body 2 can be specifically referred to in the background technology: For example, the Chinese utility model patent with the announcement number CN220562411U discloses a printing machine frame with adjustable height, including a fixed table, both sides of the outer surface of the lower end of the fixed table are fixedly installed with feet, the upper end of the fixed table is provided with a printing platform, the lower end outer surface of the printing platform is provided with a moving group, the front and rear ends of the moving group are provided with a moving frame, the upper end outer surface of the moving frame is provided with a printing box, the outer surface of one side of the printing platform is provided with a control panel, and both sides of the outer surface of the lower end of the printing platform are fixedly installed with baffles. It is a prior art and is widely used in society, so it will not be described in detail;

[0028] The driving mechanism includes a motor 17, which is fixedly connected to the middle of the lower surface of the mounting plate 8, and the motor 17 is transmission-connected to the connecting shaft 13 through a driving assembly;

[0029] The driving assembly includes a rotating shaft 15, a worm 16 and two worm wheels 14. The bottom end of the rotating shaft 15 is rotatably connected to the middle of the upper surface of the mounting plate 8. The output end of the motor 17 is fixedly connected to the bottom end of the rotating shaft 15. The worm 16 is sleeved on the side wall of the rotating shaft 15. The two worm wheels 14 are respectively sleeved on the side walls of the two connecting shafts 13. The worm 16 is located between the two worm wheels 14 and meshes with them. When the lead angle (λ) of the worm 16 is less than the friction angle (φ) of the contact surface between the worm wheel 14 and the worm 16, the transmission system of the worm wheel 14 and the worm 16 can achieve self-locking. At this time, the worm 16 can be driven to rotate clockwise or counterclockwise through an external power device, thereby achieving clockwise or counterclockwise rotation of the worm wheel 14.

[0030] During use, the electrical components in this application are externally connected to a power supply and a control switch when in use. The printing press body 2 facilitates the printing work on the substrate. When it is necessary to adjust the height of the printing press body 2, starting the motor 17 can drive the rotation of the rotating shaft 15. The rotating shaft 15 can drive the rotation of the worm 16. The worm 16 can drive the rotation of two worm wheels 14, and the rotation directions of the two worm wheels 14 are opposite. The worm wheel 14 drives the connecting strip 6 thereon to rotate through the connecting shaft 13. The connecting strip 6 can drive the support plate 4 to move vertically in the support seat 3 through the connecting column 12. Thus, the support plate 4 can drive the printing press body 2 to move vertically through the frame 1, so as to adjust the height of the printing press body 2. When the printing press body 2 is adjusted to an appropriate height, the operation of the motor 17 is paused. And during the movement of the support plate 4, the connecting column 12 can slide in the movable groove 11. The length of the connecting strip 6 extending outside the support plate 4 is relatively long to ensure that the movable groove 11 has enough length to drive the support plate 4 to move vertically. During this process, starting the motor 17 can drive the rotation of the worm 16. The worm 16 can drive the frame 1 and the printing press body 2 to move vertically through the worm wheel 14, the connecting strip 6 and the support plate 4, so as to adjust the height of the printing press body 2 according to actual needs. And after the motor 17 is powered off, due to the self-locking property between the worm wheel 14 and the worm 16, the printing press body 2 can be prevented from falling under its own gravity, improving the practicability of the device.

[0031] Referring to Figure 1 and Figure 3 , symmetrically fixed to the upper surface of the mounting plate 8 are support rods 9. The tops of the two support rods 9 are jointly connected to a fixing plate 10. The top of the rotating shaft 15 is rotatably connected to the middle of the lower surface of the fixing plate 10. The fixing plate 10 can further support the rotating shaft 15, making the rotation of the rotating shaft 15 more stable.
