Technical Field

[0001] The utility model relates to the technical field of printing head lifting devices, and particularly relates to a printing head lifting device for a screen printing machine. Background Art

[0002] A screen printing machine is a device specifically used for screen printing, also known as a screen printing equipment. It mainly consists of a frame, a workbench, a screen stretching system, a printing head, a printing platform and other components. Screen printing machines are widely used in industries such as textiles, electronic products, glassware, ceramic products, advertising signs, etc. The printing head is an important part of the screen printing machine. In the existing printing head during the lifting process, it often moves up and down through a drag chain, with a complex structure and cumbersome maintenance and repair after a failure, which is not conducive to the production and use of small enterprises. Therefore, we introduce a printing head lifting device for a screen printing machine. Content of the Utility Model

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0024] A printing head lifting device for a screen printing machine, including a printing machine body 1, a display screen 4 is fixedly connected to the left part of the front end of the printing machine body 1, a plurality of control buttons 5 are fixedly connected to the right part of the front end of the printing machine body 1, a lifting and moving device 3 is fixedly connected to the rear part of the upper end of the printing machine body 1, and a horizontal moving device 2 is movably connected to the front end of the lifting and moving device 3, and the horizontal moving device 2 is located above the printing machine body 1.

[0025] In this embodiment, the lateral movement device 2 includes a cross beam 21. In the middle of the rear end of the cross beam 21, a first slider 23 is fixedly connected. The first slider 23 has a "U" - shaped structure. A first threaded hole 24 is opened at the rear part of the upper end of the first slider 23. At the right end of the cross beam 21, a first motor 22 is fixedly connected. A chute 26 is opened at the front end of the cross beam 21. The output end of the first motor 22 is fixedly connected with a first threaded rod 25. The first threaded rod 25 is located in the chute 26. The first threaded rod 25 is movably connected to the left inner wall and the right inner wall of the chute 26 through bearings. A moving frame 27 is threadedly connected to the outer surface of the first threaded rod 25. A printing head 28 is fixedly connected to the lower end of the moving frame 27. A second slider 271 is fixedly connected to the rear end of the moving frame 27. A second threaded hole 272 is opened at the right end of the second slider 271. The second slider 271 is threadedly connected to the first threaded rod 25 and is slidably connected to the chute 26. The second slider 271 is adapted to the chute 26.

[0026] Through the above - mentioned scheme: Start the first motor 22. The first motor 22 drives the first threaded rod 25 to rotate. The rotation of the first threaded rod 25 drives the moving frame 27 to move left and right in the chute 26, thereby adjusting the lateral position of the printing head 28.

[0027] In this embodiment, the lifting and moving device 3 includes a frame 31. The frame 31 has a "U" - shaped structure. Limit slots 33 are opened at the left part and the right part of the front end of the frame 31. A second motor 32 is fixedly connected to the upper end of the frame 31. The output end of the second motor 32 is fixedly connected with a second threaded rod 34. The second threaded rod 34 is located inside the frame 31. The frame 31 is fixedly connected to the upper end of the printing body 1. The first slider 23 is slidably connected to the two limit slots 33 and is threadedly connected to the second threaded rod 34.

[0028] Through the above - mentioned scheme: Start the second motor 32 to drive the second threaded rod 34 to rotate. During the rotation of the second threaded rod 34, the first slider 23 and the cross beam 21 are adjusted in height up and down, thereby driving the moving frame 27 and the printing head 28 to adjust their positions up and down.

[0029] It should be noted that the present utility model describes a printing head lifting device for a screen printing machine. When the first motor 22 is started, the motor efficiently drives the rotation of the first threaded rod 25. Through the precise fit of the threads, the first threaded rod 25 seamlessly drives the moving frame 27 thereon to achieve smooth left - right lateral movement inside the cross beam 21. This process not only significantly improves the convenience of the lateral movement of the printing head 28, but also has a simple structure and low cost. Since the first slider 23 connected to the rear end of the cross beam 21 is slidably connected to the frame 31, and at the same time the first slider 23 is also tightly connected to the second threaded rod 34 at the output end of the second motor 32 through threads. When the second motor 32 is started, its power is quickly converted into the rotational movement of the second threaded rod 34, thereby driving the first slider 23 to flexibly lift and lower in the vertical direction. This mechanism naturally drives the overall lifting movement of the cross beam 21, the moving frame 27, and the printing head 28. It is not only structurally compact and easy to maintain, but also greatly meets the requirements of small enterprises for the flexibility and practicality of the equipment.

[0030] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above - mentioned embodiments. What is described in the above - mentioned embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
