Background

At present, most of reciprocating folding machines are full-automatic, can only automatically adjust the folding height and cannot adjust the swinging angle of a folding knife. The swing angle of the machine is determined by the curve of the cam 54 and the length of the swing rod 56 and cannot be freely adjusted (as shown in fig. 13), and the swing angles required by products with different folding heights and different material thicknesses are different, so that one machine type cannot be suitable for various products with the folding heights, the cam 54 and the swing rod 56 need to be replaced when the folding heights are replaced, and the operation is extremely inconvenient. The existing up-and-down movement of the folding knife is that a servo drive synchronous belt 50 drives a knife shaft and a folding knife to reciprocate up and down, as shown in fig. 12, the speed cannot be increased due to a plurality of reasons such as large inertia of the folding knife, the knife shaft and a transmission system, and the maximum speed is not more than 120 per minute.
