Abstract
Its mfg. method is as follows: firstly, the mixed pulp is made into paper board, then the heat-sealing glue and water-proofing oil-proofing agent are spray-coated on the paper board, then the paper board is cut into the blank, and spray-wetted and fed into hot-press host machine and formed. This lunch-box possesses boss and strengthening rib, and is high in quality and low in cost, and can be substituted for plastic lunch-box.
Description
The invention belongs to a kind of tableware or packaging for foodstuff, relate generally in a kind of paper board lunch-box with cover made by hot pressing formation and preparation method thereof.
At present, at railway transport of passengers department and quick-lunch bar, all be to use the foamed plastic lunch box, owing to bring serious " white pollution " for the environment of human survival, China has announced to ban use of plastic lunch box in some city, replaces plastic lunch box with Paper dinner pail, has become inexorable trend.Existing cardboard moulding lunch box is to have cut out paper mold in advance, adopts technology folding, molding bonded, general comparatively valuable three-ply paper material or the thicker cardboard of adopting, but intensity is still relatively poor, and lunch box on the train particularly will be layering in that to transport in the dolly load capacity very big.The wall calendar of employing paper, single gummed paper, wood-free paper or thicker cardboard or corrugated paper are also arranged, and not only cost is more expensive, because the not plasticity of cardboard and thickness are equal, thereby lunch box intensity is also relatively poor.And not adopting foldingly, the bonding process direct heat is molded can only to be short service plate of die cavity and so on, and there is difficult technical problem in the darker lunch box of compacting die cavity.
The objective of the invention is at the technical problem that exists in the prior art, and realize proposing a kind of paper board lunch-box with cover made by hot pressing formation and preparation method thereof with the purpose of paper lunch box full substitution with disabled plastic lunch box.
The technical scheme of paper board lunch-box with cover made by hot pressing formation of the present invention is: it comprises box body and the lid that links to each other with box body, be equipped with boss at the end face of lid and the bottom surface of box body, leading flank and two sides at lid and box body are the inclined-plane, be provided with the fastening limit of mutual coupling at the place of joining, inclined-plane of lid and box body, and be provided with a dead bolt that stretches out downwards in the lid forward, central part, and be provided with a keeper at the middle part of box body front, can insert wherein for the dead bolt in the lid.The front bevel and the both sides of described lid and box body are equipped with reinforcement.The inner surface of described lid and box body is coated with hot blast glue and water and oil repellent agent.
The preparation method of paper board lunch-box with cover made by hot pressing formation of the present invention, its step comprises:
(1) the press polish cardboard that adopts mixed pulp to make adds wet process again through hot blast glue and water and oil repellent agent processing and after cutting into ground paper;
(2) mould in the heat pressing forming machines is heated earlier, again to sending into the lunch box ground paper hot briquetting in the machine;
(3) to the finishing of cutting edge of the lunch box base after the moulding;
(4) stacking package.
The paper pulp of described paper boards is the mixed pulp of straw pulp and wood pulp, and the weight ratio of its straw pulp and wood pulp is respectively 70-90% and 30-10%.The main component of described hot blast glue is an ethyl acetate.Described water and oil repellent agent mainly is an Organic fluoride, aluminum sulfate, cured, rosin or alum, and wherein oil-proofing agent is 1: 3 with the weight item ratio of waterproofing agent.The processing method of described hot blast glue and water and oil repellent agent is spraying.The heating-up temperature of described mould is 150-250 ℃.
The device of making paper board lunch-box with cover made by hot pressing formation of the present invention, it comprises cardboard conveying and cutting apparatus, spraying equipment, the ground paper storage facilities, squirt equipment, hot pressing main frame and finished product pile up facility, it is characterized in that wherein hot pressing main frame by upper die and lower die, and die heater and connecting gear hand constitute.Patrix is contained in the top of counterdie, be installed on the base of main frame by its cylinder and the controllably upper and lower activity of manipulator spring, counterdie, die heater is contained in the top of patrix and the bottom of counterdie respectively, and transfer robot is contained in the exit side of main frame, squirts the feed side that equipment side is contained in main frame.
Paper tableware or paper lunch box have two kinds of production methods, and the one, with direct hot pressing of paper pulp and vacuum mold injection forming, be to be described in detail in 95108039.3 the application for a patent for invention as application number, it two is to use paper board lunch-box with cover made by hot pressing formation.The present invention adopts the higher cardboard heat pressing process of efficient, produces comparatively inexpensive practical Paper dinner pail.Adopt the cardboard of straw pulp and a small amount of wood pulp, be cut into 300mm * 250mm cardboard or become board rolls, through hot blast glue, water and oil repellent agent spraying, with add wet process, compression moulding in the counterdie of patrix that heats and heating, hot blast glue does not dissolve at 100 ℃, at high temperature with four jiaos of well-regulated thin folding line cementings, because humidification and hot pressing have increased the plasticity of cardboard, thereby produce lunch-box with cover made cheap, that there are box body and lid in thing U.S.A.And fore shaft is arranged on box body, and on lid, have to go out dead bolt downwards, and be provided with the fastening limit of mutual interlock in the junction, edge of lid and box body, be convenient to lunch box and cover completely, lock.
Major advantage of the present invention is that with straw pulp be the press polish cardboard of a small amount of wood pulp of advocating peace, and handles and processings of heating through hot blast glue and water and oil repellent agent, can hot-formingly connect lid and eat lunch box.Because paperboard surface is bright and clean, mould well-designed makes the existing enough intensity of cardboard lunch box, make price suitable again, and production efficiency is higher, and the machine floor space is little.Cardboard hot pressing lunch box will replace plastic lunch box, and in size, exterior design, lunch box bearing capacity, the waterproof and oilproof and the indeformable performance of being heated all meet or exceed the plastic lunch box level, and plastic lunch box is buried all non-degradable at underground 200 years.And Paper dinner pail just can fall in south and touches in one month, and dry regional paper needs just degraded in 2 months in the north.
