DETAILED DESCRIPTION
[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figure 1-Figure 6As shown, the automatic printing device described in the utility model includes a mounting frame 1, a motor 2 fixed on the mounting frame 1, a first main shaft 3 arranged on the motor 2 and passing through the mounting frame 1, a collar 4 fixed on the first main shaft 3, two driving rods 5 fixed on the collar 4 and arranged in a mirror image, two arc-shaped racks 6 fixed on the collar 4 and arranged in a mirror image, a special-shaped driving plate 7 fixed on one end of the first main shaft 3, a driving drum 8 rotatably arranged on the mounting frame 1, a sliding rod 9 slidably arranged on the driving drum 8, two printing rubbers 10 fixed on the sliding rod 9, a rotating A first driving connecting rod 11 movably arranged on the sliding rod 9, an intermediate rod 12 fixed at one end of the first driving connecting rod 11 and passing through the mounting frame 1, a second driving connecting rod 13 fixed on the intermediate rod 12, a transmission main shaft 14 passing through and rotatably arranged on the mounting frame 1, a driving gear 15 fixed at one end of the transmission main shaft 14, a first transmission wheel 16 fixed at one end of the transmission main shaft 14, a transmission fixed shaft 17 fixed on the mounting frame 1, a second transmission wheel 18 rotatably arranged on the transmission fixed shaft 17, and a conveyor belt 19 simultaneously sleeved on the first transmission wheel 16 and the second transmission wheel 18.When in use, fill the printing material tank with printing paste, and then turn on the motor. The rotation of the motor drives the first main shaft to rotate, thereby driving the ring to rotate, and then drives the two driving rods and the two arc-shaped racks to rotate with the axis of the ring as the center. When the driving rod rotates, the driving rod enters the groove on the driving drum and contacts the groove wall, pushing the driving drum to rotate with the axis of the slide rod as the center. According to the setting of the spiral groove, when the driving rod rotates to disengage from the spiral groove, the driving drum stops after rotating 180 degrees until the next driving rod rotates to the working position and enters another spiral groove, pushing the driving drum to rotate in the opposite direction until the driving rod and the spiral groove are disengaged. At this time, the driving drum stops after rotating 180 degrees in the opposite direction. When the driving rod When the driving drum rotates, the guide groove on the driving drum and the protrusion on the slide rod cooperate to achieve the effect of driving the slide rod to rotate.

At this time, the cylindrical protrusion on the second driving connecting rod slides in the groove in the special-shaped driving plate, and cooperates with the rotation of the special-shaped driving plate, which will drive the second driving connecting rod to intermittently rotate around the axis of the intermediate rod as the center of the circle, thereby driving the first driving The connecting rod also rotates with the axis of the intermediate rod as the center, thereby driving the sliding rod to move up and down. When the sliding rod moves downward, it will drive the two printing rubbers to move downward. At this time, one printing rubber completes the printing work and the other printing rubber completes the loading work. When the sliding rod moves upward, it will remain stationary for a period of time to rotate and replace the two printing rubbers; when in use, the rotation of the first main shaft will drive the ring to rotate, thereby driving the two arc-shaped racks to rotate. When the arc-shaped racks are engaged with the driving gear, it will drive the driving gear to rotate, thereby driving the transmission main shaft to rotate, and then drive the first transmission wheel to rotate, drive the conveyor belt to rotate, and finally drive the second transmission wheel to rotate. Since the two arc-shaped racks are set in a mirror image, they drive the conveyor belt The state of intermittent work occurs. In summary, the utility model, through mechanical transmission, cooperates to form an automated printing assembly line, liberates human resources, improves the reliability of printing work, reduces the rate of inferior products, and is driven by a motor to synchronously drive the drive rod and the drive rack to rotate, and cooperates with the specific setting of the driving drum, and finally realizes the synchronous reciprocating circular motion of the two printing rubbers, and the motor also drives the special-shaped drive plate to work synchronously, and finally drives the slide bar to slide up and down, and finally realizes the alternating work and alternating materials of the two printing rubbers, thereby improving efficiency, and through the design of the arc rack, in cooperation with the driving gear, the intermittent work of the conveyor belt is realized to ensure that the conveyor belt remains stationary during the working process of the printing rubber.
