Carton creasing device

Abstract

The invention relates to the technical field of carton processing and discloses a carton indentation device which comprises a transmission mechanism, a convex block and a concave block, wherein the transmission mechanism comprises a driving wheel, a driven wheel and a conveyor belt; the conveyor belt comprises a propulsion part and a bearing part; the propulsion part comprises a connecting plate;a plurality of openings are formed in the connecting plate; the bearing part comprises a plurality of support rods; a fixed disc and a first sliding chute are arranged on one side of the propulsion part; a fixed rod is horizontally arranged between the driving wheel and the driven wheel; the concave block is fixedly connected onto the fixed rod; a first support roller is fixedly connected with theside, close to the fixed disc, of the fixed rod; and a second support roller is in sliding fit with the side, far away from the fixed disc, of the fixed rod. The carton indentation device can adjustthe distance between the two support rollers and the sunken width of an indentation and transmits corrugated boards discontinuously to enable the quality of the manufactured corrugated boards to be higher.

Description

technical field [0001] The invention relates to the technical field of carton processing, in particular to a carton creasing device. Background technique [0002] Corrugated carton is the most widely used carton, and its consumption has always been the top of all kinds of packaging products. Corrugated boxes are rigid paper containers made of corrugated cardboard through die-cutting, creasing, nailing or gluing. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transportation packaging containers due to their superior performance and good processing performance, and have become the main force of transportation packaging. In addition to protecting the goods and facilitating storage and transportation, it also plays a role in beautifying and promoting the goods. In the forming process of corrugated cartons, the bent part must be indented before it can be successfully made into cartons. At present, the indentation mechanism of the ...

Problems solved by technology

But there is following problem in said scheme: 1, the position of being arranged on two back-up rollers in the gap is relatively fixed, can't adjust the distance between two back-up rollers, when the distance between two back-up rollers is bigger, When the protrusion is pressed down, the part of the corrugated cardboard is subjected to concentrated force, and the place where the corrugated cardboard is not in contact with the protrusion will be creased or broken

2. By setting the first indentation device and the second indentation device, only the depth of the indentation can be adjusted, but the width of the indentation cannot be adjusted

3. The above scheme uses a conveyor belt for uninterrupted transmission. When the first and second indentation devices act on corrugated cardboard, the indentation will shift, and the shape of the indentation will be irregular, making The folded edge of the corrugated cardboard is inclined, which will affect the shape and quality of the corrugated box
