Recently, the company has renovated the drying tunnel of the existing 1.8-meter, 2.2-meter five-layer and seven-layer corrugated board production line. Before the renovation, the drying channels of the two production lines used a gravity reel system. Therefore, sometimes the problem of degumming of the "ribs marks" of the cardboard and the flattening of the corrugated shape may occur. With these technical conditions that hindered the development of production and customer feedback, the company conducted in-depth research with the technical staff of relevant machinery companies in Shanghai, and in December 2009, respectively modified the two production line drying tracts at a length of 28 meters. Between the drying tunnels, 8 groups of air bag type pressure plates are arranged, which turns the original hard pressure into the current soft pressure. After practice, this configuration effectively removes the moisture in the cardboard and makes the corrugated cardboard flatter. It also reduces quality problems such as cardboard deformation and warpage. In order to ensure the safe operation of the equipment after the transformation, the company selected relevant technical personnel to go out for professional training to achieve the foreseen results. The situation after the transformation is as follows: 1. Can increase production speed and increase output The air bag type pressure plate system is more able to conform to the deformation curve of the hot plate and press the cotton belt than the gravity reel system and the spring steel plate system, so that the cardboard is close to the hot plate to obtain a good amount of heat transfer, so the vehicle speed can be increased, especially in the production of high Heavy three-layer cardboard, five or seven-layer cardboard, three-layer fine corrugated (such as E flute, F flute) cardboard effect is more significant. Second, the quality of cardboard has been effectively improved Because the air bag type pressing plate can make the cardboard adhere to the hot plate, the amount of paste can be reduced, and the cardboard is smoother and stronger. Because the air bag type pressure plate is evenly pressed and full of elasticity, the corrugated cardboard type will not be damaged, and the vertical and flat pressure values ​​can be increased to make the cardboard better in strength and feel better. Because the amount of paste is reduced and the pressure is evenly applied, the "washboard" phenomenon does not occur, and the "ribs marks" can also be significantly improved. Third, save the amount of paste Because the air bag type pressing plate can make the cardboard adhere to the hot plate, the wave tip can be thinner on the paste machine, and the amount of paste is saved (about 10% to 30% according to the statistics of the example). 4. Can save the amount of core board Due to the average and elastic pressure of the air bag type pressure plate, the cardboard corrugated shape will not be damaged, and the vertical and flat pressure values ​​can be improved. The low gram weight core paper can be used to replace the high gram weight core board. The air bag type pressure plate is extremely flexible, so it will not flatten the cardboard. As we all know, if the corrugated height is increased or decreased by 0.1mm, the core paper usage rate will increase and decrease by 1.5 to 2.5%. The use of core paper can reduce 150,000 to 250,000 meters. If the air bag type pressure plate, under other conditions unchanged, can reduce the amount of core paper by reducing the height of the corrugated roller teeth, in order to achieve the purpose of cost savings. Five, maintenance and repair are almost zero Due to the removal of the gravity reel, there is no need to adjust the gravity reel, and there is no longer any need to replace bearings or regularly grease. Through practice, it is conservatively estimated that the air bag type pressure plate air bag can be used for three years, and the chain can be used for 10 years. 6. Can shorten the hot plate and save space Because the heat transfer of the air bag type pressure plate is comprehensive, it is far better than the heat transfer of the line of the gravity reel, and the length of time required for the synthesis and drying and flattening of some cardboard boards can be shortened. 7. It can automatically adapt to the speed of the car and the change of the door width As we all know, the faster the cardboard production speed, the more heat is required, and the slower the speed, the less heat is required, otherwise it will cause poor bonding or cardboard bending. The control system of the air bag type pressure plate automatically tracks the speed of the production line, and automatically adjusts the ballast pressure according to different speeds to obtain the best cardboard quality. 8. The produced cardboard helps improve production efficiency It may be difficult to estimate the depreciation and consumption of each machine per hour, but if the cardboard is soft or bent, the speed of the printing slotting die cutting machine will inevitably slow down, and the same reason will affect the production of the printing folding box machine. Speed, in this way, not only increases the cost of the product, but also may affect the company's reputation due to delayed delivery times or the production of bad products. The cardboard corrugated type is strong, which increases the customer's recognition of the company, which virtually increases the company's advantage when competing with its peers. All in all, the company's overall plan for the equipment transformation of the corrugated board production line is implemented step by step, and gradually promoted according to the enterprise development plan, so that the company can develop scientifically and harmoniously in an environment of fierce market competition.
