[New content] In view of the problems existing in the previous screen printing presses, the creator has developed a screen printing press with a double platform, and based on this, the lower platform lifting device is mechanically designed for stable and accurate lifting. For its main creative purpose. … In order to achieve the aforementioned invention objective, the technical hand used in this creation is to provide #screen printing machines with dual platforms. The screen printing machine is equipped with a body, one end of which is provided with a lifting device and a receiving device. The lower platform driven by the lifting device, one upper flat a, ten upper mouths, one above the upper platform, and a printing mechanism connected to the machine body, the machine body is provided with an upper slide rail and a-slide rail on each side for upper and lower rails, respectively. Lower platform along its displacement, i, lower flat two: do not accept-the upper drive device,-the lower drive device can be driven up and down; horizontally reciprocating alternately, characterized by: The lifting device contains-for The first cam driven by the power source is a cam-driven lifting plate. The inside of the machine is provided with a power source. The power source is connected to a drive shaft, which is passed through a cam stand, and the upper side of the fixed seat is pivoted. A fixed seat is provided on one side, and the 忒, 忒 jacks correspond to the cam and the free end is provided with a top pulley; and the body is located adjacent to the cam and penetrates through the lower guide seat and _ ± &胄 several branches 4. The guide rods are in common contact with each other. The upper surface of the lower guide seat is for the top pulley and the bottom surface of the lower platform. A connection shaft is fixed at the bottom. D = 'The bottom of the lifting plate is fixed with a number of joints with the lower platform. Sub-sigma slab, which is located under and above the lifting plate; and "'for the end of the connecting shaft to abut against the top surface of the lower guide seat. The body is provided with a buffer at the direction of the end of the printing structure. Σ Backward σ, the upper and lower platforms on both sides of the machine are moved forward and backward at the position set by the printing mechanism.-1 ° There is also a 刖 sensor and two rear sensors. The rear sensor is electrically connected up and down. Privately buffered ^ lower transmission device, and the rear sensor is located in the effect system can be obtained as follows: 1 Juicing device is designed with a cam and lever to mechanically drive, lower, lower platform lift, Its mechanical movement will be precisely and stably through the cam curve, eliminating the disadvantage of instability in lifting. A 2 · The cam drives the ejector to drive the flat-shaped lifting plate to raise and lower the flat mouth. Therefore, the lower platform is lifted in a face-to-face support mode. Its effective increase of the contact area makes the lower platform not to shake and the printing process is natural. There will be no incomplete phenomenon due to the lower platform shaking. 3 · The upper and lower platforms first meet the sensor to decelerate, and then cooperate with the buffer to buffer the positioning. This two-stage positioning method is slow and stable, and can be equipped with a solenoid to enhance the positioning of the upper and lower platforms. The positioning of the printing position is accurate and the service life is long. [Embodiment] This creation is a screen printing machine with dual platforms.
