DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0019] Please refer to Figures 1-5The utility model provides a technical solution: a double-speed platform device, including a fixed guide rail carrier 1, a turntable 2 and a tray 3 fixedly arranged inside the printer, the turntable 2 is slidably arranged on the top of the fixed guide rail carrier 1, and the tray 3 is arranged on the top of the turntable 2.

[0020] Further, in order to increase the extension rate of the tray 3, a sliding frame 4 is fixedly connected to the bottom of the middle turntable 2, a sliding groove 12 slidably adapted to the sliding frame 4 is opened on the top of the fixed guide rail carrier 1, a servo motor 5 is fixedly connected inside the sliding frame 4, rotating rods 6 are rotatably arranged on both sides of the middle turntable 2, the front and rear parts of the surface of the rotating rod 6 are fixedly connected to the first pulley 7, a first belt 8 is transmission-connected between the two first pulleys 7 on the same plane, an upper ear plate 9 is fixedly connected to the top of the first belt 8, and the upper ear plate 9 is fixedly connected to the bottom of the tray 3, the bottom of the first belt 8 is fixedly connected to the lower ear plate 10, and the opposite sides of the two lower ear plates 10 are respectively fixedly connected to the front and rear sides of the fixed guide rail carrier 1, and a driving mechanism 11 is arranged between the servo motor 5 and the rotating rod 6;

[0021] As a detailed explanation: the driving mechanism 11 includes a second pulley 111, the second pulley 111 is fixedly arranged on the surface of the output shaft of the servo motor 5, the surface of the left rotating rod 6 is fixedly connected with a third pulley 112, and a second belt 113 is transmission-connected between the third pulley 112 and the second pulley 111, the front and rear sides of the top of the turntable 2 are fixedly connected with guide rails 13, and the front and rear sides of the bottom of the tray 3 are fixedly connected with guide rail sliders 14 slidably adapted to the guide rails 13.

[0022] When in use, start the servo motor 5, and the servo motor 5 starts its output shaft to drive the second pulley 111 to rotate. The rotation of the second pulley 111 forms a transmission match with the third pulley 112 and the second belt 113, and synchronously drives the left rotating rod 6 to rotate through its transmission match. The left rotating rod 6 synchronously drives the right rotating rod 6 to rotate through the transmission match of the first pulley 7 and the first belt 8. When the left rotating rod 6 drives the right rotating rod 6 synchronously through the transmission match of the first pulley 7 and the first belt 8, the left rotating rod 6 and the first pulley 7 will drive the turntable 2 and the tray 3 to move to the right and unfold in disguise due to the fixed setting of the lower belt of the first belt 8. While the tray 3 moves with the turntable 2, it will also accelerate the movement of the tray 3 again on the basis of movement due to the transmission of the first belt 8 and the fixed match between the upper layer of the first belt 8 and the tray 3. When the tray 3 needs to be reset, it only needs to reverse the servo motor 5 and start it.
