Specific embodiments

[0023] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] Refer to Figures 1 to 4 , the present utility model provides a lifting structure of an electric cylinder for the beam of a four-column printing machine, which is used in the screen printing occasion. A lifting structure of an electric cylinder for the beam of a four-column printing machine includes a main body 1 of a mesh frame structure arranged in a rectangle, which serves as the main frame support of the printing machine. A printing beam 2 is arranged on the main body 1 of the mesh frame structure and is used to support and transmit printing materials. Printing knife groups 3 are also arranged on both sides of the longer sides of the main body 1 of the mesh frame structure. These knife groups are fixed on both sides of the printing beam 2 and are used to cut the printing materials. A four-axis screw lifting system 4 is arranged at the lower end of the main body 1 of the mesh frame structure and is used to lift or lower the printing machine. The system includes an electric cylinder 41 arranged below the end of the main body 1 of the mesh frame structure and is used to lift or lower the printing machine. A first angle converter 42 is arranged at the lower end of the electric cylinder 41 and is used for angle adjustment and synchronous control. A base 45 is arranged at the lower end of the first angle converter 42 to stabilize the entire structure. The first angle converters 42 are connected to each other by a screw shaft 46 to maintain the integrity and stability of the structure. The electric cylinder 41 and the screw shaft 46 are both arranged in a U shape to increase the stability and durability of the structure.

[0025] Before the staff starts the printing machine through the control system, ensure that all components are correctly installed and in the initial position. According to the type and thickness of the printing material, the staff adjusts the height of the four-axis screw lifting system 4 through the control system to ensure the appropriate contact pressure between the scraper assembly and the printing material. Then, fine-tune the angle through the first angle converter 42 to ensure the precise alignment of the printing knife group 3 with the printing material. Once all settings and adjustments are completed, the staff starts the printing process through the control system. The transmission line feeds the printing material into the device, and at the same time, the printing knife group 3 cuts according to the preset program. After the printing task is completed, the staff lowers the printing beam 2, and returns the printing knife group 3 and the printing beam 2 to the initial position through the electric cylinder 41 and the angle converter, and then turns off the printing machine.

[0026] Furthermore, a transmission belt 5 is arranged on the two U-shaped electric cylinders 41, and the other end of the transmission belt 5 is connected to both ends of the opening of the main body 1 of the mesh frame structure. Arranging the transmission belt 5 to connect the electric cylinder 41 and the main body 1 of the mesh frame structure is convenient for maintenance and replacement, and effectively reduces the complexity and cost of the entire mechanical system.

[0027] Furthermore, the longer sides of the four-axis screw lifting system 4 are formed by two screw shafts 46, which are connected by a second angler 43. The second angler 43 is connected to the screw shafts 46 at both ends, and the second angler 43 is also equipped with a servo motor 44. The second angler 43 is connected to the first angler 42 via the screw shafts 46, forming a stable frame structure. This structure helps reduce vibration and bending during the printing process, thereby ensuring printing accuracy and quality. When the printing press starts, the control system instructs the servo motor 44 to rotate, thereby driving the second angler 43 for precise angle adjustment.

[0028] Furthermore, an adjustment knob 12 and a graduated rod 13 are provided at each end of the longer sides of the frame structure body 1. The adjustment knob 12 allows the operator to adjust the position of the printing blade assembly 3 or the printing pressure by rotating it, enabling adjustments in small increments to ensure accuracy and consistency during the printing process. The graduated rod 13 is typically used in conjunction with the adjustment knob 12, providing clear reference marks so that the operator can accurately set and read the adjustment amount, thereby improving overall work efficiency.

[0029] Furthermore, the printing blade assembly 3 includes: a printing scraper 31, a scraper head 32, and a scraper connector 33. The printing scraper 31 is disposed on the upper portion of the screen frame body 1. The printing scraper 31 is fixed to both sides of the longer side of the screen frame body 1 and is parallel to the shorter side. It moves horizontally along the longer side of the screen frame body 1. Guide rails 21 are provided on both sides of the printing beam 2. The scraper head 32 is fixed to the guide rails 21 on both sides of the printing beam 2. The servo motor 44 drives the synchronous belt to control the horizontal translation of the lower blade assembly. One end of the scraper head 32 is connected to the scraper connector 33, and the upper and lower ends of the scraper connector 33 are connected to the printing scraper 31. The scraper head 32 is fixed to the guide rails 21 on both sides of the printing beam 2 to ensure that it can slide smoothly while maintaining proper contact with the printed material. The printing scraper 31 is fixed on both sides of the longer side of the frame structure body 1 and is arranged parallel to the shorter side, which helps to maintain precise alignment between the scraper and the printing material, ensures accurate transfer of the printing pattern, and increases stability during the printing process.

[0030] Furthermore, the main frame structure 1 of the electric cylinder 41 is equipped with a pressure spring 11 for pressure regulation. This provides the necessary cushioning during the movement of the electric cylinder 41, reducing vibration and shock during operation, protecting mechanical components and extending the life of the equipment. It also maintains stable contact pressure between the printing beam 2 and the printed material, ensuring print quality.

[0031] The utility model provides a four-column printing press beam electric cylinder lifting structure with the following advantages:

[0032] 1. The four-axis screw lifting system is set up to facilitate the lifting or lowering of the printing press, and the synchronization and stability of the lifting device are ensured when in use.

[0033] 2. Each first angle turner is connected by a screw shaft to maintain the integrity and stability of the structure.

[0034] 3. Fully automatic operation, no manual operation is required after the program is set, effectively reducing manpower.

[0035] 4. The device is equipped with adjustment knobs and scale rods to ensure the accuracy and consistency of the printing process, while making it convenient for staff to accurately set and read the adjustment amount.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
