Movable rear paper-neatening device adapted to various types of paper sizes

Abstract

The invention relates to a movable rear paper-neatening device adapted to various types of paper sizes. The rear paper-neatening device, a front paper-neatening device, a left paper-neatening device and a right paper-neatening device form a paper-receiving part of a die-cutting machine, and the paper-receiving part is used for the stacking and neatening of paper after die-cutting receiving. The rear paper-neatening device comprises a longitudinal beam, supporting plates, moving blocks, chains, cross beams, and a paper-neatening fence. The number of the chains is two, and the two chains are respectively disposed at two sides of the longitudinal beam. The number of the cross beams is two, and the two cross beams are disposed above the two chains in a parallel manner. The number of the moving blocks is two, and the two moving blocks are respectively connected to the central segments of the two chains and move along with the chains. The number of the supporting plates is two, wherein the internal ends of the supporting rods are connected with an end part of the longitudinal beam, and the external ends of the supporting rods are connected with the moving blocks. The paper-neatening fence is vertically connected to the longitudinal beam. Compared with the prior art, the structure of the supporting plates meets requirements that the vertical distance from the longitudinal beam to a connection line between the two moving blocks is 10 mm, the structure enables the distance between the rear paper-neatening device and the front paper-neatening device to be increased by 10 mm on the original basis, and the rear paper-neatening device can be suitable for paper in large sizes.

Description

technical field [0001] The invention relates to a paper trimmer on a die-cutting machine, in particular to a rear trimmer which can be moved and adapted to various paper specifications. Background technique [0002] Die-cutting machines used to cut paper on the market can generally process a wide range of paper sizes, and can meet customers' requirements for different paper sizes as much as possible. However, due to the structural limitations of die-cutting machines, general die-cutting machines have a maximum paper size limit. The die-cut paper length of the commonly used die-cutting machine is 740mm. And customers sometimes ask for the uncommon 750mm paper specification. [0003] The paper length of 750mm can pass through most of the devices of the die-cutting machine. There is almost no need to change the internal structure of the existing die-cutting machine, only the paper delivery part of the die-cutting machine is too small, and 750mm paper cannot pass through the ...
