[0023] The following is a detailed description of a multi-layer trolley for loading Tray plates of the present invention in conjunction with the accompanying drawings.

[0024] like Figure 1-2As shown, an embodiment of a multi-layer trolley for loading Trays of the utility model includes a support frame 1 and a plurality of universal wheels 102 arranged at the bottom of the support frame 1, and the support frame 1 can be moved by the universal wheels 102; a handrail 101 is fixedly provided on the support frame 1, and the staff can push the handrail 101 to push the support frame 1 to move freely. Among them, the support frame 1 includes an opening for the Tray 105 to be placed (the opening is away from the handrail 101), and a plurality of supporting components for supporting the Tray 105 are installed in the support frame 1, and the supporting components are arranged in a stacked manner, and the supporting components are installed inside the support frame 1 from top to bottom, so as to support multiple Trays 105 placed in the support frame 1. After the support frame 1 is pushed to move, multiple Trays 105 can be transported at one time (the number of the transported Trays 105 is 15 layers or 20 layers, etc.), so as to improve the transportation efficiency of the electronic paper. In the process of pushing the support frame 1 to move, in order to prevent the Tray 105 from detaching from the supporting components, a clamping mechanism for clamping the Tray 105 is provided on the supporting components of each layer; specifically, after placing multiple Trays 105 on different supporting components from the openings of the support frame 1, the Tray 105 is clamped by the clamping mechanism on the supporting components, so that in the process of pushing the support frame 1 to move, the Tray 105 is always stably placed on the supporting components, and after the support frame 1 is pushed to the specified position, the clamping mechanism is automatically unlocked, and the Tray 105 can be removed from the supporting components to proceed to the next process.

[0025] like Figure 3 As shown, the Tray 105 includes a rectangular frame 10501 (the shape of the electronic paper is also rectangular), and a tray bottom 10502 is provided at the bottom of the frame 10501. The frame 10501 and the tray bottom 10502 are combined to form a Tray 105 for holding the electronic paper. In addition, a clamping slot 10503 for a clamping mechanism to be clamped is provided at the bottom of the frame 10501. After the Tray 105 is placed into the supporting frame 1, the frame 10501 is partially placed on the supporting mechanism. After the Tray 105 is stabilized, the clamping mechanism is clamped into the clamping slot 10503, thereby clamping the Tray 105. Additionally, a positioning protrusion 10504 is provided on the top of the frame 10501, and a positioning hole 10505 is provided on the bottom thereof for the protrusion 10504 to pass through. When multiple trays 105 are stacked together, the positioning protrusion 10504 of the lower tray 105 will pass through the positioning hole 10505 of the upper tray 105, thereby allowing the multiple trays 105 to be stably stacked together.

[0026] The supporting component includes a pair of crossbars 103 placed at the same height and fixed to the supporting frame 1. The crossbars 103 are arranged opposite to each other. A plurality of pulleys 104 are arranged on the crossbars 103 for supporting the frame 10501 of the Tray 105, and the pulleys 104 are arranged in an array in the horizontal direction. First, one end of the Tray 105 is placed on the pulley 104, and then the Tray 105 is pushed so that the frame 10501 of the Tray 105 slides on the pulley 104. Under the action of the pulley 104, the Tray 105 can be supported and the Tray 105 can be better placed in the supporting frame 1. In addition, a clamping mechanism is arranged at one end of the crossbar 103 close to the opening of the supporting frame 1. After the Tray 105 is placed steadily, the clamping mechanism is clamped into the clamping slot 10503.

[0027] like Figure 4-5 As shown, the clamping mechanism includes a fixing seat 106 arranged on the cross bar 103, and the fixing seat 106 is placed at one end of the cross bar 103 close to the opening of the support frame 1, wherein a clamping block 109 which can be automatically clamped into the clamping slot 10503 is provided on the fixing seat 106; after the Tray 105 is placed firmly, the clamping block 109 is automatically clamped into the clamping slot 10503, thereby clamping the Tray 105. Furthermore, a rotating shaft 107 which is axially arranged horizontally and axially perpendicular to the length direction of the cross bar 103 is provided on the fixing seat 106, one end of the clamping block 109 is fixedly connected to the rotating shaft 107, and the other end is used to be clamped into the clamping slot 10503 to clamp the Tray 105, and the clamping block 109 swings on the fixing seat 106 through the rotating shaft 107, so that the clamping block 109 can be clamped into or out of the clamping slot 10503; when the clamping block 109 and the fixing seat 1 A spring 1011 is provided between 06 for applying force to the block 109. The spring 1011 applies a thrust to the block 109 so that the block 109 is stuck in the slot 10503. When a force is applied to the block 109 to disengage from the slot 10503, the spring 1011 will be compressed. After the force on the block 109 stops, the block 109 automatically resets under the action of the compressed spring 1011, and the block 109 can be automatically stuck in the slot 10503. In addition, in order to limit the block 109, an arc-shaped slide groove 1010 is provided on the block 109, and a fixing column 108 is also provided on the fixed seat 106, and one end of the fixing column 108 is placed in the arc-shaped slide groove 1010. When the block 109 swings on the fixed seat 106 through the rotating shaft 107, the fixing column 108 slides in the arc-shaped slide groove 1010, and the swing angle of the block 109 is limited under the action of the fixing column 108 and the arc-shaped slide groove 1010. In addition, the block 109 can also be arranged on the fixed seat 106 through an elastic member (metal spring or torsion spring, etc.), so that the block 109 is elastically connected to the fixed seat 106, and the block 109 can also be automatically inserted into the slot 10503.

[0028] After the support frame 1 is pushed to the specified position, it can be docked with the feeding device (the feeding device is used to transport the Tray 105 in the support frame 1 to the next process). While docking, a force is applied to the block 109 to disengage the card slot 10503, thereby realizing automatic unlocking of the Tray 105; in order to facilitate the docking of the support frame 1 with the feeding device, positioning wheels 1012 are provided at the top and bottom of the support frame 1, and the positioning wheels 1012 can be used to better position the support frame 1 when docking with the feeding device; in addition, magnets 1013 for stable docking are also provided at the top and bottom of the support frame 1. After the support frame 1 is positioned by the positioning wheels 1012, the support frame 1 is attracted to the feeding device through the magnets 1013, thereby realizing the docking process between the support frame 1 and the feeding device.

[0029] In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.
