Paper board producing unit

Abstract

The invention provides a paper board producing unit, and belongs to the field of paper board production devices. The paper board producing unit comprises a machine frame, an upper half piece, a lower half piece, a squeezing mechanism and four linkage mechanisms. The squeezing mechanism comprises a pressing cylinder, a first slide block and a first reset spring. A positioning slide way is arranged on the machine frame. The first slide block is arranged in the positioning slide way in a sliding mode. The pressing cylinder is arranged at the top end of the first slide block in a rotating mode. The linkage mechanisms are arranged between the pressing cylinder and a gauge roller and between the gauge roller and a front guide roller and used for making the pressing cylinder, the gauge roller and the front guide roller synchronously move. The pressing cylinder, the gauge roller and the front guide roller are made to synchronously move through the linkage mechanisms, the pressing cylinder presses surface paper of a surface paper cylinder, the pressing cylinder drives the surface paper cylinder to rotate synchronously while rotating, the surface paper between the pressing cylinder and the gauge roller and the surface paper between the gauge roller and the front guide roller are both kept tensioned, pattern printing incompleteness caused by surface paper looseness is avoided, and meanwhile the quality of paper boards is prevented from being influenced by surface paper overlapping.

Description

technical field [0001] The invention relates to the field of cardboard production equipment, in particular to a cardboard production unit. Background technique [0002] Cardboard in the known technology is also called cardboard, which is a thick paper sheet formed by processing various pulps and interlaced fibers. The current known cardboard production technology, whether it is corrugated cardboard or honeycomb cardboard, has defects such as huge assembly line equipment, an investment of more than 5 million to 10 million per production line, and poor water resistance of the finished cardboard. [0003] The domestic invention patent application with the application number of 201210140498.2 provides a kind of cardboard production equipment, which effectively improves the above problems, but there are still many problems, the more prominent problem is that the face paper cylinder and the embossed roller are passively rotating , when the speed of the front guide roller or the r...

Problems solved by technology

At present, the known cardboard production technology, whether it is corrugated cardboard or honeycomb cardboard, has defects such as huge assembly line equipment, investment of more than 5 million to 10 million per production line, and poor water resistance of finished cardboard.

[0003] The domestic invention patent application with the application number of 201210140498.2 provides a kind of cardboard production equipment, which effectively improves the above problems, but there are still many problems, the more prominent problem is that the face paper cylinder and the embossed roller are passively rotating , when the speed of the front guide roller or the rear guide roller changes, such as slowing down, especially at the moment when the knife board cuts the cardboard, the movement of the cardboard will stagnate to a certain extent, and the surface paper tube and flower roller will be under the action of inertia Continue to rotate at a certain angle, so that the surface paper between the surface paper cylinder and the pattern roller, and between the pattern roller and the leading roller will loosen, resulting in the fact that the surface paper cannot form a complete pattern under the action of the pattern roller, and may also cause the surface paper to pass through the leading roller. The surface paper is piled up and deformed, which affects the quality of the cardboard after production
