Description

Technical Field

[0001] The invention relates to the technical field of spiral quick-freezing machines, in particular to a spiral quick-freezing machine with a differential speed conveying device. Background Art

[0002] The spiral quick freezer is an energy-saving quick freezing equipment with compact structure, wide application, small footprint and large freezing capacity.

[0003] At present, when freezing items in an orbital spiral quick freezer, if the items are placed too densely, the mesh belt will turn around the drum and the inner side of the mesh belt will shrink, causing the items to pile up and become too high. In this way, the items will be blocked by the support arms on the legs and cannot move with the mesh belt, causing the items to pile up higher and higher, and then lift up the upper mesh belt, eventually making the machine unable to work.

[0004] For example, a spiral quick freezer disclosed in Chinese patent publication number CN203177564U includes a quick freezer and a conveyor belt. The quick freezer has an outer shell and a rotating cylinder with a vertical axis, and a spiral track is provided inside the outer shell. The conveyor belt includes an inner chain, an outer chain, and a mesh belt connected between the inner chain and the outer chain. The inner chain abuts against the rotating cylinder, and the outer chain is slidably connected to the spiral track. A rotating shaft is provided, and a plurality of transmission sprockets are fixed at intervals on the rotating shaft, and the transmission sprocket engages the outer chain. It has the following advantages: the rotating cylinder rotates, and the inner chain is driven to spirally move through the static friction between the rotating cylinder and the inner chain. The rotating shaft rotates, and the outer chain is driven to spirally move through the cooperation of the sprocket and the chain, so as to ensure the synchronization of the spiral motion of the inner and outer chains, avoid the jamming phenomenon, and have a long service life.

[0005] When the above device is loading items, the items will be transported at a constant speed, which will cause accumulation. When the number of items increases, the transportation cannot be carried out, causing the machine to stop. The staff will sort the items, and their work efficiency and quality will be affected.

[0006] Therefore, we propose a spiral quick-freezing machine with a differential conveying device to solve the above problems. Summary of the invention
