Technical Field

[0001] The utility model relates to the technical field of plastic cutting machines, in particular to a cutter for plastic production. Background Technique

[0002] When plastic is produced and processed, a cutting machine is usually needed to cut plastic plates into pieces for subsequent use.

[0003] Currently, when cutting plastic plates, the plastic plates are usually manually pushed under the cutting machine for cutting. However, since the plastic plates need to be cut both horizontally and vertically, usually after the plastic plates are vertically cut, the positions of the plastic plates are readjusted and then horizontally cut. As a result, not only is the labor intensity high, but the cutting efficiency is also low, affecting the production and processing of plastic plates. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cutter for plastic production, so as to solve the problem that the existing fixture directly clamps the steel pipe and may cause damage when operated improperly as mentioned in the above background technique.

Then, by starting Motor 3, the output shaft of Motor 3 drives the gear to rotate. Since the gear is meshed with Motor 3, the rotation of the gear ring drives the rotating column to rotate, driving the cylinder 1, the connecting rod, Motor 1 and the cutting knife to rotate, facilitating the transverse cutting of the longitudinally cut plastic sheet. Similarly, by starting Motor 2, the cutting knife can move inside the connecting frame, facilitating the transverse cutting of multiple groups of longitudinally cut plastic sheets, thus improving the cutting efficiency.
