Description

Technical Field

[0001] This utility model belongs to the technical field of trimming systems, specifically relating to independent trimming systems. Background Technology

[0002] The trimming system is a mechanism installed on a cardboard trimming machine to trim the edges of the cardboard. The trimming system mainly consists of a power shaft and trimming blades. The power shaft is driven to rotate by the power system of the trimming machine, which in turn causes the trimming blades to rotate and trim the edges of the cardboard.

[0003] The existing trimming system has the following defects: (1) When the trimming system mechanism is used for trimming the edge of the cardboard, the trimming position of the trimming knife needs to be adjusted. Since the trimming knife is fixed on the power shaft, the trimming machine needs to be stopped and the trimming knife needs to be disassembled before the position adjustment is made, which makes the adjustment inconvenient. Therefore, we propose an independent trimming system. Utility Model Content

A serrated trimming knife is installed at one end of the upper knife holder, and a lower trimming knife is installed at one end of the lower knife holder. A first power shaft runs through the interior of both the upper knife holder and the serrated trimming knife, and a second power shaft runs through the interior of both the lower knife holder and the lower trimming knife. Synchronous grooves are respectively formed on the surfaces of the first and second power shafts. Synchronous blocks are provided inside the synchronous grooves, and the synchronous blocks are respectively fixed on the inner walls of the corresponding upper and lower knife holders. An adjustment groove with a circular cross-section is formed on the surface of the other end of the upper knife holder, and a toggle mechanism is connected inside the adjustment groove.

[0006] Preferably, the actuating mechanism consists of a lead screw, a lead screw cylinder, and a transverse shift plate. The lead screw cylinder is mounted on the transverse shift plate, the lead screw passes through the inside of the lead screw cylinder, and one end of the transverse shift plate is placed inside the adjustment groove.

[0007] Preferably, the longitudinal section of the transverse shift plate is rectangular, and the longitudinal section of the lead screw cylinder is convex.
