A guide sleeve 141 cooperating with the guide rod 13 is also installed on the movable plate 14; that is, the movable plate 14 moves between the first vertical plate 11 and the second vertical plate 12 along the guide rod 13 through the first driving mechanism 15 and the guide sleeve 141;

[0018] A group of receiving transmission pulley assemblies 16 are respectively installed on the inner surface of the movable plate 14 opposite to the second vertical plate 12, and the two groups of receiving transmission pulley assemblies 16 are arranged at the same height to ensure that the receiving tray is in a horizontal state on the receiving transmission belt; in this embodiment, the receiving transmission pulley assembly 16 on the inner side of the movable plate 14 includes an active synchronous pulley 161 installed on the inner side of the movable plate, two driven synchronous pulleys 162, and a receiving transmission belt 163 connected thereto respectively. Similarly, the receiving transmission pulley assembly 16 on the inner side of the second vertical plate 12 also includes an active synchronous pulley 161 installed on the inner side of the second vertical plate 12, a driven synchronous pulley 162, and a receiving transmission belt 163 connected thereto respectively; a synchronously driving member of the receiving transmission pulley assembly is also installed on the first vertical plate 11. The second driving mechanism 17 of the component 16, and the output shaft 171 of the second driving mechanism 17 and the active synchronous pulley 161 of the receiving transmission pulley assembly 16 on the movable plate 14 are connected to each other for relative axial movement, that is, the active synchronous pulley 161 on the movable plate 14 can rotate under the drive of the output shaft 171, and can move along the output shaft axis 171; in this embodiment, the second driving mechanism 17 is also a rotary servo motor, and its output shaft 171 is a non-circular shaft, which passes through the movable plate 14 and is connected to the active synchronous pulley 161 provided on the inner side of the movable plate 14 and the second vertical plate 12, and simultaneously drives the two active synchronous pulleys to rotate, and then drives the two receiving transmission belts 163 to run synchronously through the driven synchronous pulley 162;

[0019] Furthermore, the tray closing machine also includes a machine table 2, on which an x-direction moving module 3 is installed, the tray correction mechanism 1 is installed on the x-direction moving module 3 and is driven by the x-direction to move horizontally, the receiving conveyor belt 163 of the tray correction mechanism 1 is arranged along the y-direction, and a suspension 18 is also provided on the mounting base 11 of the tray correction mechanism 1, and a tray pushing mechanism 4 is installed at the end of the suspension 18, and the tray pushing mechanism 4 is located above the receiving conveyor belt 163; a z-direction lifting platform 5 is also installed on the machine table 2 and on the side of the x-direction moving module 3, and a tray box 6 is installed on the z-direction lifting platform 5; the x-direction moving module 3 controls the x-direction movement of the entire tray correction mechanism 1 On the one hand, the position of the tray correction mechanism 1 is adjusted according to the position of the tray discharged by the front transmission crawler, so that the tray correction mechanism 1 can better receive the tray. On the other hand, after receiving the tray, the x-direction position of the tray correction mechanism 1 is adjusted again according to the specifications of the tray. At the same time, the tray correction mechanism 1 automatically corrects the position of the tray, so that the discharge position of the tray correction mechanism corresponds to the position of the inlet of the tray box of corresponding specifications at the rear, so as to complete the action of pushing the tray into the tray box 6; the z-direction lifting platform 5 controls the height of the tray box 6, so that the tray racks of the corresponding layers in the tray box 6 can receive the tray layer by layer, and the trays can be loaded layer by layer from top to bottom or from bottom to top;

When the tray is not pushed, the y-direction cylinder 43 and its pushing block 44 are located above the tray. When the tray is in place, the z-direction cylinder 41 is actuated to move the y-direction cylinder 43 and the pushing block 44 downward as a whole to the front of the tray. The y-direction cylinder 43 controls the pushing block 44 to push the tray backward, so that the tray enters the tray box 6 on the z-direction lifting platform 5 from the receiving conveyor belt 163;

[0021] Through the above structure, when receiving the material, the position of the movable plate 14 is in a convenient position for receiving the material according to the position of the material tray discharged from the front transmission crawler and the width of the material tray.
