Creation Instructions (1) [Technical Field to which the New Type belongs]-This creation is about the release structure of a four-column screen printing machine, especially a release that accurately controls the displacement path of the screen through a limit slot and a stopper. Edition · Structure. [Previous technology] The screen printing process of the screen printing machine is that after the object to be printed is placed in position, the screen lifting structure drives the screen to position, followed by scraping the screen to print the screen, but due to the screen, printed matter, and printed pattern The sizes are different, and the ink viscosity and thickness of the printed matter are different. There are different appropriate screen positioning. When there is a gap between the screen and the printed matter, the ink cannot be printed on the screen when the scraper moves the screen. ≫ The layout is printed on the object to be printed. In addition, if the b screen is closely attached to the object to be printed, after the scraping is completed, the ink will be halo or spread on the object to be printed. surface. Please refer to the Republic of China New Patent Bulletin No. 3 7 3 5 7 8. The creation name is the improvement of the off-plate structure of the screen printing press. The creation discloses a reduction motor connected to the main motor of the screen printing press. The main motor drives the deceleration. The output shaft of the motor is connected to a rotating arm. The rotating arm is provided with a fixed block, which is connected to a clutch device. The clutch device includes a roller, a sprocket and a chain. The above components control the lifting of the screen. However, the above structure has the following shortcomings: (1) The roller and sprocket are driven by a motor, which drives the lifting and lowering of the chain control screen®. Such actions and positioning cannot achieve high accuracy. Requirements. (2) The motor, reduction motor, roller and chain are all located in

Creative Instructions (2) One side of the screen is easy to cause the same side to tilt or shift when controlling the screen. (3) If you want to overcome the above-mentioned tilt or offset, you must add an eccentric structure or an angle compensation device, which not only increases the number and complexity of components, but also causes a relative cost problem. (4) The screen is driven by a chain to move up and down, and its displacement path is not easy to control, which makes the screen unable to move out of the plate synchronously with the printing device and loses the effect of the off-plate structure. [New content] The main purpose of this creation is to solve the above-mentioned deficiencies and avoid the existence of the deficiencies. This creation is to provide a lifting device that can accurately control the displacement path of the screen release. In order to achieve the above purpose, the creation is a release structure of a four-column screen printing machine, which includes a machine and a printing device connected to the support cylinder and the machine. There is a supporting column. The printing device defines a printing section. A screen plate is provided below the printing section, a printing unit is provided above, and a lifting unit is arranged around the printing device. The lifting unit is provided with a driving member. It is a servo motor and is connected to the transmission part. The transmission part is screwed to the driving part and the driving part is pivotally connected to the screen. The lifting unit and the printing device are provided with a limiting slot and a limiting member. Adjust the screen plate and the printing unit to move up and down synchronously, and the limit slot and the stopper control the displacement path of the screen plate, if it forms a four-column screen printer's release structure.
