(2) the bamboo juggle is inserted in the softening water that contains alkali 2-4%, soaks 100 ℃ of heating, softened in time 3-5 hour, remove softening water,, insert in the insulation groove and be incubated bamboo juggle spray Cleaning for High Capacity,
(3) the bamboo juggle is cut into slices with chopping machine, the bamboo-wood thin piece thickness that is cut into is the 0.2-0.9 millimeter, and the temperature of bamboo juggle is 60 ℃-80 ℃ during section,
(4) drying process is selected the moisture content in the FAR INFRARED HEATING evaporation bamboo-wood thin piece for use, is divided into three sections baking temperatures, and one section baking temperature is 30 ℃-40 ℃, 1 minute-5 minutes time; The two-stage drying temperature is 40 ℃-60 ℃, 1 minute-3 minutes time; Three sections baking temperatures are 80 ℃-100 ℃, and 1 minute-4 minutes time, the dried water ratio of bamboo wood chip is 15-23%,
(5) the locating back surface temperature of flattening mill is 100 ℃-110 ℃, is the bamboo-wood thin piece pressing of 40-60 millimeter to folding thick, time 8-12 minute, and pressure 12-20 ton.
(6) by the 20-25 millimeter specification cut-parts that extend again of the every limit of required container length and width size,
(7) to the two-layer bamboo-wood thin piece gluing of mutual applying, to fit, the machine direction intersection angle between the adjacent two layers bamboo-wood thin piece of applying is 10 °-170 °, the bamboo thin slice, wooden thin slice, or bamboo-wood thin piece can make up separately and paste, or hybrid combining pastes,
(8) the container sheet material of fitting is put compression molding in the heating and mould pressing make-up machine, the punch of mould and the surface temperature of die are 120 ℃-150 ℃.
Method of the present invention can maximally utilise bamboo and wood materials, cut bamboo-wood thin piece thin, evenly smooth, method for making economy, easy, effective, low cost of manufacture, material source is extensive.The bamboo-wood thin piece packing container of making has good toughness, and elasticity and intensity can effectively be protected food, and the packing container easy-clear after the use is easily dissolved, easy-weathering corrosion, and also recyclable utilization can not cause environmental pollution and to the chemical damage of human body.The packing container good permeability, and tough and tensilely can effectively prolong the food preservation time in the container.
The invention will be further described below in conjunction with embodiment.
Embodiment
Select for use the bamboo wall not scratch, indentation and the 3-5 setation bamboo that damages by worms, bamboo, mean diameter 8-10 centimetre, the about 8-15 millimeter of bamboo wall thickness.Timber is selected birch for use, the poplar low price, and wood fibre is soft, free machining timber.Bamboo wood is cut into chunks by the every limit of the container dimensional length and width 25-30 millimeter that extends again, the ring of cutting into chunks is punched, ring is punched diameter and is about 30 millimeters and gets final product, be beneficial to the infiltration of soften flux water, the impurity elimination of being removed contamination in bamboo juggle surface again, clean up, the bamboo juggle is inserted in the softening water that alkalinity is 2-4%, soak 100 ℃ of heating, time 3-5 hour, soften, softening process carries out in the softening pond of automatic warming system is arranged usually, softening water is removed in softening back, with bamboo juggle spray Cleaning for High Capacity, inserts in the insulation groove and is incubated.To the section of bamboo juggle, bamboo juggle continuous cut is adopted in section with chopping machine, and slice thickness is the 0.2-0.9 millimeter, optimum thickness is the 0.3-0.4 millimeter, the temperature of bamboo juggle remains on 60 ℃-80 ℃ during section, and to guarantee the softness number of bamboo wood, the bamboo juggle reaches said temperature usually in the insulation groove.Drying equipment in the drying process can be canal drier, adopts the moisture content in the FAR INFRARED HEATING evaporation bamboo-wood thin piece, is divided into three sections baking temperatures, one section baking temperature is 30 ℃-40 ℃, length of the halt 1 minute-5 minutes, the two-stage drying temperature is 40 ℃-60 ℃, the best is 55 ℃, 1 minute-3 minutes time, three sections baking temperatures are 80 ℃-100 ℃, and the best is 100 ℃, 1 minute-4 minutes time, Best Times 2 minutes, dried bamboo-wood thin piece water ratio is 15-23%.
Flatten operation and adopt the hydraulic pressure flattening mill, the locating back surface temperature of flattening mill is 100 ℃-110 ℃, can adopt the flattening mill of four lamination slab constructions, be laminated into the bamboo-wood thin piece pressing that thickness is the 40-60 millimeter to three simultaneously, locating back pressure is the 12-20 ton, the pressing time is 8-12 minute, flattens bamboo-wood thin piece.
Flatten the back by the 20-25 millimeter specification cut-parts that extend again of the every limit of the required container length and width of customer requirement size, cut-parts should guarantee that length and width all are beneficial to fit along machine direction.
The glue that last glue process adopts is non-poisonous gelatine or fish glue and plant, or animal protein glue, with gluing machine the two-layer bamboo-wood thin piece gluing of mutual applying is fitted, machine direction intersection angle between the adjacent two layers bamboo-wood thin piece of fitting is 10 °-170 °, available bamboo thin slice layer by layer, or wooden thin slice makes up separately.Also but hybrid combining pastes, available two-layer bamboo thin slice is fitted up and down mutually, two-layer up and down bamboo lamellae cross angle is 30 °-150 °, the best is that the 90 ° of three fashionable bilevel length of bamboo thin slice of selecting for use of laminating is suitable machine direction, the length of interlayer is that mutual applying of vertical fibers direction forms, or adopts opposite machine direction setting.The also available veneer of interlayer replaces forming mixolimnion and fits.The machine direction cross-over design of bamboo-wood thin piece is to decompose internal stress makes thin slice avoid crackle in forming process, improves intensity and toughness simultaneously.
Die press technology for forming is that the container sheet material of fitting is put compression molding in punch-die, should select heating mould for use, the surface temperature of mould molding face should be 120 °-150 °, should guarantee the sphere that is of three junctions of mould, and three planes seamlessly transit, it is the 1.0-1.1 millimeter that the punch-die mould closes post gap, and clamping pressure is the 5-8 ton.
Trimming process step adopts trimmer, cuts out the bamboo wood limit of going to container four limits unnecessary, again with sander to the four jiaos of sandings in container four limits of bamboo wood, remove the corner burr, it is sliding to reach four marginal raies.
The dry disinfection operation is to the wood of the bamboo after moulding container drying, removing the moisture content that still contains in the container about 10%, drying process can adopt container process of passing through tunnel formula drier drying again, more dried container is sterilized with ultraviolet germicidal lamp, sterilization back packing plastic packaging, finished product is made in vanning.
Mechanical equipment of the present invention is a conventional mechanical devices, and glue is by being purchased product on the market.
In a word, the inventive method is simple and easy to do, and cost of manufacture is low, and the smooth light of the packing container of making is clear, attractive in appearance clean, has good toughness and elasticity and intensity, is a kind of method for making of the bamboo-wood thin piece food packaging container of being convenient to promote.
