A special equipment for improving the quality of corrugated cardboard

Abstract

The objective of the invention is to provide a special apparatus for improving the quality of a corrugated board. According to a technical scheme in the invention, the special apparatus is composed ofa raw paper bearing device, a preheating device and a corrugated board bonding device, wherein the raw paper bearing device is composed of a main bench, a flat paper bearing roller, two drawn-paper guiding rollers, a lifting slide rack and a lifting snapping rack; the preheating device consists of a steam conveying pump, a steam inlet, a steam conveying pipe, two steam filtering pipes and a heating plate; and the corrugated board bonding device is composed of a bonding operation table, a feed paper carrying rack, a gluing roller, two squeezing rollers and three auxiliary pressing rollers. Thespecial apparatus employs an automatic gluing manner, bonds and extrudes corrugated boards in virtue of hot steam, and can adjust a paper feeding state by itself to adapt to the processing of corrugated paper with different specifications; the split-type structural design of the special apparatus is favorable for later maintenance; double-power paper feeding is more stable and free of offset; andthe special apparatus is small in size, low in energy consumption and reduced in operational pollution, and improves product quality.

Description

technical field [0001] The invention relates to the field of corrugated cardboard processing, in particular to a special equipment for improving the quality of corrugated cardboard. Background technique [0002] With the concept of green, environmental protection and energy saving gradually gaining popular support. More and more product packaging design concepts are gradually developing from complex and luxurious to simple and economical. Corrugated packaging has gradually replaced aluminum, iron, and wooden packaging and has occupied an important position in the market. Corrugated paper is a plate made of corrugated corrugated paper formed by processing cardboard and corrugated sticks. Its two important indicators are burst strength and compressive strength. Different types of corrugated paper have different bursting strength and compressive strength. With the continuous improvement of the production process, more and more types of corrugated paper are produced and applie...

AI Technical Summary

Problems solved by technology

The processing line of corrugated cardboard is also very complicated, and usually requires multiple branch machines to complete the processing of different steps. Although the continuous advancement of science and technology has provided a lot of convenient production equipment, most of the processing operations of corrugated cardboard still use base paper racks. Single and double-sided corrugating machine, preheater, vertical and horizontal cutting machine, stacker and supporting steam heating system, air compression system, rubber circulation system and other equipment, but because corrugated paper is paper, its moisture-proof effect It is relatively poor, and it cannot withstand high and low temperatures, so it will cause many problems during processing, especially in the early stage of processing, it is the need for more precise positioning and fusion of corrugated paper and cardboard that needs to be bonded, which is for existing equipment. The work is not very good. The corrugated paper and cardboard are often not conveyed smoothly, resulting in deviation, and they are not corrected in time when they are bonded. Therefore, the texture of the synthesized corrugated paper is misaligned, which brings troubles to subsequent cutting and other processing. many inconveniences
