Description

Technical Field

[0001] The utility model relates to the field of paper towel cutting machines, and more specifically, to an automatic longitudinal paper towel cutting mechanism. Background Technique

[0002] The height of the rivets in the steering wheel is a key characteristic dimension. If the dimension is out of tolerance, it is impossible for personnel to quickly identify it visually. Once it flows out to the vehicle assembly plant, it will cause the production line to stop and result in serious complaints. At present, the traditional detection method is to detect the height of the four rivets after they are installed in the steering wheel to check whether they are within the specified error range.

[0003] For example, the automatic longitudinal paper towel cutting mechanism disclosed in the authorized publication number CN 211194098 U includes an operation table and a cutting blade, and also includes a lifting table.
