Description

Technical Field

[0001] The utility model relates to a high-position automatic tray stacking machine, belonging to the technical field of food tray stacking. Background Art

[0002] During the food processing process, the food to be processed needs to be transferred on the processing production line through conveying equipment. Some smaller foods are transferred by placing them on pallets. The pallets can facilitate the movement of food on the conveying device and the stacking and storage of food.

[0003] The existing stacking and unstacking machines use cylinders to lift and lower food plates. There are two groups of clamping cylinders and one group of clamping and lifting cylinders on each side. After a single food plate is delivered to the stacking machine, the stacking machine starts, firstly lifts up the food plate, and the clamp extends to the bottom food plate. The lifting device falls back to stack the plates. This cycle continues until the set number of layers of food plates is fully stacked. To unstack the plates, it is also necessary to lift up all the food plates above the bottom food plate and then pull out the bottom food plate. This structure requires all the food plates on the upper end to be lifted up by the lifting cylinders when unstacking or stacking the plates. This requires the lifting cylinders to bear a large force on the one hand, and it is easy to deform the food plates on the other hand.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
