Description

Technical Field

[0001] This application relates to the field of pallet manufacturing technology, and in particular to a transfer rack for drinking water barrels. Background Technology

[0002] Bottled water offers convenience, delivered directly to users, and its clean quality and low hardness make it popular. However, the large size and variety of water barrels mean that simply stacking them in water stations and warehouses takes up significant space and affects inventory levels. Therefore, racks are often used to elevate the barrels off the ground, increasing the number of barrels per unit area and thus improving storage capacity.

[0003] Existing bottled water production companies widely use 4×4 water barrel stacking unit pallets with a self-weight of up to 22kg. After the finished water is filled on the production line, the automatic palletizer places 16 barrels of finished water onto the reserved bottom pallet. Then the palletizer lays a middle partition, and this process is repeated to stack 3 to 4 layers of water barrels. Finally, a forklift is used to move them to the warehouse area.

[0004] Using existing pallets to stack water-filled barrels significantly increases the overall variety of barrels. During long-distance transport, the diameter of the 18.9-liter barrel is much larger than the diameter of the end-opening pipe. If the ground is uneven during transport, or if the barrels tilt while being lifted by a forklift, they are prone to slipping or shifting, potentially falling and getting damaged. In large factory areas with large production volumes, forklifts are needed for long-distance transport of multi-layered barrels, further increasing the breakage rate due to these issues. This not only increases production line costs, but the existing barrel stacking racks are also unsuitable for long-distance transport and large-scale drinking water production and transportation.

[0005] The information disclosed in the background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

In use, after the snap-fit ​​protrusion 123 passes through the large hole 122, it pushes the upper cover frame rod 124 into the small hole 121 of the lower cover frame, thus achieving snapping. Small hole 121 and large hole 122 refer to the fact that the diameter of small hole 121 is smaller than that of large hole 122.

[0063] In one specific embodiment, longitudinal reinforcing ribs 21 are arranged in pairs on the two opposite sides of the arc of the receiving groove 3 and / or the reverse arc groove 142; the longitudinal reinforcing ribs 21 are respectively connected to the transverse arc ribs 22 in the receiving groove 3; the reverse arc groove 142 is respectively connected to the arc reinforcing ribs 141 in the reverse arc groove 142.

[0064] In one specific embodiment, it includes: a side reinforcing rib 131; the side reinforcing rib 131 extends vertically outward from the receiving groove 3 and / or the reverse arc groove 142 to form a bottom plane edge 11 and a side plane edge 14.
