Problems solved by technology

[0002] In the post-press collating machine of a large printing machine, the upper paper and the bottom paper need to be glued together on all four sides, while the middle paper only needs to be glued to one side, and the middle paper except for the pasted side, the other three sides are smaller than the upper paper and the lower paper , so in the continuous collation, it is necessary to die-cut the edge of the folder. The die-cutting form is two horizontal rolling and one longitudinal rolling die-cutting the next edge. The wear resistance puts forward very high requirements. The general design uses a round anvil cylinder and only a small piece of blade is fixed on the knife cylinder. The blade is easily broken due to impact, and the service life of the blade is short. The general structure design is in the case of blade wear. It is prone to incomplete slitting and cannot cut the paper edge. At this time, it can only be shut down for debugging, which reduces the efficiency

Embodiment

[0012] As shown in Figure 1, it is a structural schematic diagram of a jumping rolling device, and the jumping rolling device is composed of a blade 1, a cam anvil 2, a connecting block 3, a fixed shaft 4, a positioning cap 5, and an eccentric knife Axle 6, bearing 7, gland 8 and anvil shaft 9 form.

[0013] First pass the fixed shaft 4 through the connecting block 3 and then lock it with screws, then put the eccentric shaft 6 into the hole on the connecting block 3, fix it with the positioning cap 5 and pass through the connecting pin and tighten it with the top screw, and then A bearing 7 is installed at one end, the blade 1 is a round blade, fastened on the bearing 7 by screws, the gland 8 is fixed on the center of the blade 1 by screws, the cam anvil 2 is set directly below the fixed blade 1, and the anvil shaft 9 passes through Cam anvil cylinder 2, and cam anvil cylinder 2 is fixed by jack screw.

[0014] As shown in FIG. 2 , which is a schematic diagram of the structur...

Abstract

The jumping thread cutting device consists of a cutting blade screwed to a bearing, a cam anvil tube below the fixed blade, a connecting block, a fixing shaft over the connecting block, a locating cap, an eccentric cutter shaft inside the hole in the lower part of the connecting block and with one end fixed by the locating cap and the other end with bearing, a bearing, a gland for fixing the center of the cutting blade, and an anvil tube shaft penetrating the cam anvil tube to fix it. The present invention has the advantages of compact structure, high reliability, low cost, high longitudinal cutting precision and capacity of regulating the pressure to the longitudinal cutter during operation.

Description

technical field [0001] The invention relates to a jumping rolling line device, which is used for a collating machine behind a printing machine and belongs to the technical field of printing machinery. Background technique [0002] In the post-press collating machine of a large printing machine, the upper paper and the bottom paper need to be glued together on all four sides, while the middle paper only needs to be glued to one side, and the middle paper except for the pasted side, the other three sides are smaller than the upper paper and the lower paper , so in the continuous collation, it is necessary to die-cut the edge of the folder. The die-cutting form is two horizontal rolling and one longitudinal rolling die-cutting the next edge. The wear resistance puts forward very high requirements. The general design uses a round anvil cylinder and only a small piece of blade is fixed on the knife cylinder. The blade is easily broken due to impact, and the service life of the bl...
