Mold table device of uncoiling die cutting machine

Abstract

The invention relates to an all-servo mold table device of an uncoiling die cutting machine. The device comprises a mold table main body frame, an upper die cutting platform, a lower die cutting platform, a feed driving mechanism for guiding products to enter a die cutting station, and a discharge driving unit for guiding the products to shift out of the die cutting station; the feed driving mechanism and the discharge driving mechanism are both fixedly mounted on the lower die cutting platform; the lower die cutting platform is connected with a mold table driving unit; the die table driving unit controls the lower die cutting platform to move up and down; and the lower die cutting platform and the upper die cutting platform are pressed for die cutting of the products. Compared with the prior art, the device adopts an all-servo control and stick clamping mode to simplify mechanical structure and to improve the die cutting speed and the production efficiency; and through arrangement ofthe lower die cutting platform capable of moving, a lower mold is always bonded with the products during die cutting, and conveyed papers and the mold table are always maintained on the same plane, sothat the floating in the mold table is reduced, the up-down travel of the mold table is reduced, and the die cutting frequency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of die-cutting machines, in particular to a mold table device of an unwinding die-cutting machine. Background technique [0002] Die cutting is a process that paper packaging products must go through. The traditional die-cutting machine sends the pre-stacked sheets of paper intermittently to the flat die table for die-cutting through the chain, tooth row, and cam mechanism, and then leaves the die table with the paper in its mouth through the tooth row. This design is relatively mature and the operation is relatively stable, but the production efficiency is low, and the requirements for machining and installation are high. It is suitable for sheet-fed production. When encountering roll paper products, it can only be solved by cutting the sheet first and then die-cutting. When the existing production equipment is produced, the mold table moves up and down, and the paper is sent into the mold table through th...

Problems solved by technology

This design is relatively mature and the operation is relatively stable, but the production efficiency is low, and the requirements for machining and installation are high. It is suitable for sheet-fed production. When encountering roll paper products, it can only be solved by cutting the sheet first and then die-cutting.

When the existing production equipment is produced, the mold table moves up and down, and the paper is sent into the mold table through the nip roller. The paper is unstable after entering the mold table. During operation, the paper needs to stop in the mold table to die-cut, and the die-cutting efficiency is relatively low. And the die cutting is not precise enough
