Multi-directional adjustable knife changing mechanism of dividing and cutting machine

Abstract

The invention relates to the technical field of cutting devices, in particular to a multi-directional adjustable knife changing mechanism of a dividing and cutting machine. The dividing and cutting machine comprises a beam, two wall boards, an annular dividing and cutting knife and a knife changing mechanism, the knife changing mechanism comprises a support arm and a support platform, the support arm is a U-shaped groove with flat bottom, the support platform is mounted in the U-shaped groove and higher than the groove, a lifting mechanism for lifting the support platform is mounted at the bottom of the U-shaped groove, and a translation mechanism capable of regulating the support platform in the horizontal direction is mounted at the side wall of the U-shaped groove. The multi-directional adjustable knife changing mechanism of the dividing and cutting machine is capable of enabling the support platform to support a dividing and cutting roller firstly through regulating the lifting mechanism; the whole knife changing process is easy to operate, the user does not need to demount the whole dividing and cutting roller to change the knife, the re-correction for the dividing and cutting roller is avoided, the structure is simple, the use is facilitated, and the changing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of cutting devices, in particular to a cutter changing mechanism of a slitter that can be adjusted in multiple directions. Background technique [0002] At present, in the process of film, paper, composite material or non-woven fabric production, its width is determined according to the production machine, and the general width is 6m. Then cut into different widths according to customer needs when selling. Generally, the cutting knives of the slitting machine are circular cutting knives. When the knives are used for a long time and need to be polished or replaced, the entire slitting roller needs to be disassembled, and then the knives must be polished or replaced. The disassembly process is long. And after the installation is completed, the slitting rollers will be calibrated, which greatly wastes manpower and material resources and increases production costs.

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to overcome the need to grind or replace the cutting tool in the prior art when the tool has been used for too long, it is necessary to disassemble the entire cutting roller, and then grind or replace the tool, the disassembly process is long, and After the installation is completed, it is necessary to correct the slitting roller. The present invention provides a multi-directional adjustable slitting machine tool change mechanism, which can make the support table support the slitting roller first by adjusting the lifting mechanism, and then Adjust the translation mechanism so that the center of gravity of the slitting roller falls on the center of the support table to ensure the stability of the slitting roller, then adjust the lifting mechanism so that the support table can strongly support the slitting roller, and then fix one end of the slitting roller The device is opened to replace the cutting knife. The whole process is easy to operate. It is not necessary to disassemble the entire slitting roller to replace the cutting knife. It also avoids re-calibration of the slitting roller. The structure is simple, easy to use, and the replacement efficiency is high.
