Description

Technical Field

[0001] The invention relates to the technical field of coils, and in particular to a super-large coil changing mechanism. Background Art

[0002] The super-large copper coil is a new product developed by copper tube manufacturers to meet the needs of the market. It has been widely recognized and accepted by the market because it is beneficial to copper tube users in reducing process waste, continuous production, improving production efficiency and reducing production costs. Its production process is also constantly improving. The traditional process uses online annealing to roll the soft copper tube onto a wooden pallet. Since online annealing has problems such as uneven performance of the head and tail of the copper tube, low production efficiency, high energy consumption, and high scrap rate, it is gradually replaced by roller hearth furnace annealing. During roller hearth furnace annealing, special stainless steel pallets are required for transportation, and after annealing, the copper tube needs to be transferred from the stainless steel pallet to the wooden pallet for transportation packaging. On the one hand, the super-large copper coil is heavy, and on the other hand, the copper tube after annealing is soft. The existing conventional tray exchange is to insert the sling into the inner ring of the copper coil and lift it for transportation. There will be problems such as flattening the bottom copper tube due to the heavy roll, and bumping and damage of the inner and outer rings of the copper tube during transportation, which seriously affects the quality of the copper tube.
