Abstract
The utility model discloses a jet heating device for paper dining boxes (cups) forming machines, which is mainly characterized in that an electrothermal air tube is adopted, and the adhered region of the paper board of the paper dining boxes (cups) is heated directly by jetting hot air. The jet heating device for paper dining boxes (cups) forming machines is composed of the electrothermal air tube, a temperature controller, a one-way throttle valve, an air pump, a connecting line, an air distribution device, and a heating nozzle. The jet heating method can use cold moulds to be pressed in and formed. The cost of the moulds is low and the forming efficiency is high. The disadvantages that the paper board adhered moulds and the moulds pressed in region of the heating method of the common moulds are baked yellow and contaminated, and the color is changed are overcome. The quality of the formed paper dining boxes (cups) is enhanced.
Description
The utility model relates to the processing unit (plant) of the general preservation apparatus of food or food.
Along with food and catering trade are strengthened day by day to the requirement of nuisancelessization of packaging material, easily reclaiming, easy natural degradation, various paper package boxes (cup) etc. just progressively replace plastics package, as papery fast food lunch-box, papery goblet, papery milk, fruit juice, wine box or the like.Be used for the cardboard of this class packing, its inner dispersion or surperficial coated have thermoplastic.After the printing of cardboard stamping-out, adhesion-molded by heating and mould pressing on carton (cup) forming machine.
Existing paper lunch-box (cup) forming machine mostly adopts the mold heated method, and the heating cardboard is adhesion-molded when mold pressing, and promptly the hot briquetting mould is transmitted to cardboard by mould with heat.For guarantee bonding effectively fast, the temperature of mould must be much higher than in the cardboard (on) melt temperature of plastics.This mold heated method has produced following problem:
1. die cost height.Also to control mold temperature because of heater being arranged in the mould, the mould structure complexity, cost is higher.
2. efficient is low.Owing to rely on mold heated, heat is passed by mould needs the time to the cardboard interlayer, so the matched moulds time is long.
3. sticking to mould.Because the mold temperature height, when compression molding, plastics in the cardboard and fiber etc. can adhere on the mould.
4. scalding.Because the mold temperature height, when compression molding, fiber etc. can the dehydration flavescence in the cardboard.
5. stain.When continuously shaped, be bonded on the mould plastics and fiber etc. and can transfer on the forming paper cutlery box (cup), form and stain.
The scalding that brings by mold heated and stain the organoleptic quality that variable color has reduced forming paper cutlery box (cup).
The purpose of this utility model is to overcome the shortcoming that prior art exists, and a kind of cardboard bonder that is used for paper lunch-box (cup) forming machine is provided.
For achieving the above object, adopting the characteristics of organization plan is that an electric heating air hose is arranged, and its front end is by pipeline be connected in series one-way throttle valve and air pump, and the rear end of electric heating air hose connects air partition device through pipeline, connects some nozzles behind air partition device.The quantity of nozzle depends on that cardboard needs the number of bond site.Every nozzle all is arranged at the both sides of corresponding bond site cardboard.
The course of work of the present utility model: when cardboard during in the mold pressing position, one-way throttle opening of valves certain hour, the hot-air that air pump drives in the electric heating air hose sprays to the cardboard bond locations by linking pipeline and air partition device by nozzle, make the paperboard surface temperature reach the melt bonded temperature of plastics, the rapid matched moulds of mould (cold mould) in the make-up machine makes the cardboard mold pressing be bonded into paper lunch-box (cup) at this moment.
Advantage of the present utility model:
1. because mould need not heat, can significantly simplify mould structure, reduce die cost, prolong die life;
2. enhance productivity since hot-air directly to heat cardboard quick, thereby shorten the production time;
3. owing to adopt cold mould, the plastics of cardboard and fiber are difficult for adhering to mould, and fiber also is difficult for the dehydration flavescence in the cardboard;
4. shaping paper lunch-box (cup) bond site is not stain.
The drawing explanation:
Accompanying drawing is the utility model organization plan schematic diagram.
Further specify organization plan and embodiment with reference to accompanying drawing:
The utility model is the jet heater that is matched in semi-automatic paper meal (cup) forming machine, and its organization plan as shown in drawings.It is made up of electric heating air hose 1, temperature controller 2, one-way throttle valve 3, air pump 4, connecting line 5, air partition device 6 and nozzle 7.The outside of electric heating air hose is insulation layer 1A, can adopt glass mat; Adiabatic porous heat accumulating 1C can adopt the porous ceramics piece, and resistance heating wire 1B places in the hole of porous ceramics piece.Every nozzle 7 places the both sides of the need bond site of cardboard 8, to paperboard surface direct injection hot air.Hot air temperature is set control by adjustable bi-metal temperature controller 2, and the hot-air emitted dose was regulated by 3 opening times of one-way throttle valve, and after the jet heating of cardboard reached the requirement temperature, mould 9 matched moulds immediately was bonded into shape with the cardboard mold pressing.
We have tried out in the papery mess-tin and have been shaped, and adopt eight nozzles to be arranged at the both sides of four bond site of cardboard, and forming effect is good.Its every technical parameter is listed in table 1.
The semi-automatic fast food paper lunch box forming machine of table 1 parameter jet heating device bleed pressure 0.4～0.6MPa heating tube size 80 * 200mm heating tube power/temperature 1.5KW/260 ℃ heating tube 5～10 fens temperature controller adjustable bimetals preheating time temperature controller SJK-300 type jet time/tolerance 1S/0.8L nozzle configuration/number circle/8 mold pressing retention time 1S production efficiency-1000/hour
