[0023] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0024] like Figure 1-3 As shown, the utility model provides a low-level automatic tray stacking machine, including a frame, wherein the frame includes a horizontal supporting frame and side frames disposed on both sides of the bracket, a conveying device is provided on the supporting frame for transferring food trays, and a top plate 2 is provided in the middle position of the supporting frame and is driven by a cylinder to move up and down.

[0025] A food tray lifting device is respectively provided on the two side frames, and the food tray lifting device comprises a retractable support plate 8 and a second cylinder 13. The support plate 8 supports the bottom of the food tray after being extended, and the second cylinder 13 drives the support plate 8 to slide up and down.

[0026] The food tray lifting device further comprises a first cylinder 11 , which is connected to the supporting plate 8 .

[0027] The food tray lifting device also includes a connecting plate 12, a second sliding seat 10 and a transverse guide rod 9 slidably installed in the second sliding seat 10. The support plate 8 is arranged toward the inside of the frame, and the back side of the support plate 8 is fixedly connected to the front end of the transverse guide rod 9. The rear end of the transverse guide rod 9 is fixedly connected to the telescopic shaft of the first cylinder 11 through the connecting plate, so that the telescopic movement of the first cylinder 11 drives the support plate 8 to telescope.

[0028] The food tray lifting device also includes a first sliding seat 7 and a vertical guide rod 6. The second sliding seat 10 and the first cylinder 11 are installed on a support frame. The support frame is slidably installed on the vertical guide rod 6 through the first sliding seat 7. The telescopic rod of the second cylinder 13 is connected to the support frame. The second cylinder 13 telescopes and drives the support plate 8 to move up and down.

[0029] The conveying device includes a driving shaft 3 arranged at its front and rear ends, sprockets are installed at both ends of the driving shaft 3, a conveying chain 5 is wound around the sprockets on the same side of the conveying device, and the driving shaft 3 is driven by a driving motor 4.

[0030] The specific working principle of the utility model:

[0031] When stacking plates, when the first food plate is conveyed to the conveying device, the top plate 2 lifts up the food plate. At this time, the supporting plate 8 is in a low position. The first cylinder 11 drives the supporting plate 8 to extend to support the food plate, and then the top plate 2 falls back; when the second food plate is conveyed to the conveying device, the second cylinder 13 drives the supporting plate 8 to rise to a high position, the top plate 2 lifts up the second food plate, and then the supporting plate 8 retracts and drops to a low position and then extends again, so that the supporting plate 8 is supported to the bottom of the second food plate, and finally the top plate falls back. According to the above process, the plates are stacked step by step from the bottom.

[0032] When removing the trays, the top plate 2 lifts up the stack of food trays. At this time, the support plate 8 moves to a high position, and then the support plate 8 extends to the bottom of the second-to-last food tray. Then the top plate 2 drives the first-to-last food tray to fall back, and the conveying device transports it away; the support plate 8 drops to a low position, and the top plate 2 rises again to lift up the stack of food trays. The support plate 8 shrinks and rises to a high position and then extends to the bottom of the third-to-last food tray. The top plate 2 drives the second-to-last food tray to fall back. According to the above process, the trays are removed step by step from the bottom.

[0033] When stacking and disassembling the food trays, the stacking and disassembling are both performed from the lower end of the food trays. The device does not need to change the structure of the device, nor does it need to change the stroke of each cylinder to achieve the disassembly and stacking of the food trays, and has good versatility.

[0034] The above is an example of the best implementation of the utility model, and the parts not described in detail are common knowledge of ordinary technicians in this field. The protection scope of the utility model is based on the content of the claims, and any equivalent transformation based on the technical inspiration of the utility model is also within the protection scope of the utility model.
