Description

Technical Field

[0001] The utility model particularly relates to a mobile driving structure of a gantry of a hot-melt screen printing machine. Background Art

[0002] Existing technology: Screen printing is also called "screen printing". Screen printing refers to using a silk screen as a base and making a screen printing plate with images through a photosensitive platemaking method. Printing is based on the basic principle that the mesh holes of the screen printing plate with images and texts can pass through the ink, while the mesh holes of the non-image and text parts cannot pass through the ink. The traditional screen production process is cumbersome and very complicated: the materials needed are: screen frame, mesh, photosensitive glue, film, exposure lamp, hair dryer. The screen plate includes a screen frame and mesh. First, brush the photosensitive glue on the finished screen plate (mesh), wait for the photosensitive glue to dry, and then use the film to expose it. The black area of ​​the film plays a role in shielding the exposure light, so that the photosensitive glue does not solidify when the plate is exposed, while the transparent non-black area will be exposed and solidified by the light. After the exposure is completed, the uncured photosensitive glue is evenly rinsed with water, and then dried, repaired, etc. Therefore, the design and development of hot-melt screen printing machines have gradually begun. The existing hot-melt screen printing machines have been basically formed, and can drive the print head and pressure roller to print the screen by the movement of the gantry. However, the design of the moving structure of the gantry is not mature. If the gantry is offset or other irregular movements occur during the movement of the gantry, it will have a great impact on the effect of the printing plate. Therefore, it is very necessary to study and optimize the moving drive structure of the gantry. In view of this, the utility model proposes a moving drive structure of the gantry of a hot-melt screen printing machine. Utility Model Content

The above definitions are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0016] like Figure 1-3 As shown, the utility model provides a mobile driving structure of a gantry of a hot-melt screen printing machine, including a base frame 1, on which a gantry 6 is arranged, and the gantry 6 is driven to move by a driving structure, and a guide structure is arranged on the base frame 1, and the gantry 6 can be driven to move in the direction of the guide structure by the driving structure, and the base frame 1 is provided with a support frame 11 below the gantry 6, and the support frame 11 is fixed by fixing bolts 12.

[0017] The driving structure includes a servo motor 2 installed on a base frame 1, and the output shaft of the servo motor 2 is connected to a rotating shaft 3 through a conveyor belt. The servo motor 2 can drive the rotating shaft 3 to rotate. Driving wheels 4 are installed on both sides of the rotating shaft 3. The base frame 1 is equipped with driven wheels 7 at symmetrical positions of the driving wheels 4. An open belt 5 is sleeved on the driving wheel 4 and the driven wheel 7. The gantry 6 is fixedly connected to the open belt 5 and can move with the open belt 5.

[0018] The guide structure includes a fixed frame 8 symmetrically arranged on the base frame 1, a guide rail 9 is installed between the fixed frame 8, the guide rail 9 is horizontally and symmetrically arranged, and a slider 10 is arranged on the outer side of the guide rail 9, the slider 10 is fixed to the gantry 6, and can limit the movement of the gantry 6 in the direction of the guide rail 9.

[0019] Two sliders 10 are provided, respectively disposed on both sides of the gantry 6 . The sliders 10 are fixed to a right-angle connecting plate by bolts, and the gantry 6 is also fixed to the right-angle connecting plate by bolts to achieve fixation and synchronization with the sliders 10 .

[0020] The guide structure includes a guide rail base 13 disposed on the base frame 1 , and a sliding seat 15 capable of moving on the guide rail base 13 is disposed on the upper surface of the guide rail base 13 , and the sliding seat 15 fixes the gantry 6 .

[0021] The two sliding seats 15 are symmetrically arranged, and a mounting plate 16 is fixedly mounted on the two sliding seats 15, a fixing member 17 and a driving frame 18 are mounted on the mounting plate 16, the fixing member 17 is fixedly connected to the gantry 6, and the driving frame 18 is fixedly connected to the opening belt 5, and the driving frame 18 can move with the opening belt 5, so that the gantry 6 can be driven to move by the opening belt 5.
