Description

Technical Field

[0001] This utility model relates to the field of raw material tape production and processing technology, specifically to a raw material tape slitting and wrapping cooling and crack prevention device. Background Technology

[0002] In the production process of raw material tape, the cooling and crack prevention device after slitting and winding tape needs to be combined with temperature control and process optimization to solve the problem of cracks caused by uneven cooling or stress concentration in the material.

[0003] In the prior art, application number 202311693546.5 discloses a cooling device for raw material tape production, including an outer frame and a heating roller. A cooling groove is installed and connected inside the outer frame near the lower part of the heating roller, and a grinding roller is connected above the cooling groove at the other end away from the heating roller. The above device can only transport and cool a single raw material tape. The raw material tape is fed separately after being cut, which greatly reduces the working efficiency. Furthermore, the tension of the raw material tape cannot be adjusted during the material transport process, and local stress concentration occurs during the winding process after cutting, resulting in material tearing.
