Abstract
The present invention relates to a gas intake and exhaust automatic balance filling process and a package bag. After powder materials or particulate materials driven by gas flow enter the package bag from a filling opening, material feeding gas entering a bag body is exhausted from micropores formed in exhaust material filter layers embedded and connected to the inner parts of the bag body walls, and the exhaust amount is approximately equal to the gas intake quantity. The powder materials and the particulate materials are accumulated in the bag body. The automatic exhaust package bag is composed of the filling opening and the bag body made of airtight moisture-proof soft fabric, wherein soft fabric connected to the exhaust material filter layers is embedded into the bag body walls on the upper part of one end of the filling opening, and the outer side is fixedly covered with a moisture-proof layer. The filling process and the package bag have good economic and social benefit.
Description
The present invention relates to a kind of air-flow that adapts to the high speed machine equalization and drive powder or granules inlet and outlet automatic balance pouring method and Filling bag.It is powder or granules that many products are arranged in chemical industry, metallurgy, building material industry field, as alumina powder, cement or the like, the packaging bag of this series products needs moistureproof, and good airtight soft lining is done packaging bag generally all to use anti-soak properties, as plastic-coated glass wool cloth lining, but the cost height.In order to improve output and packaging efficiency, present large and medium-sized enterprise mostly adopts the efficient fast speed pressed gas of mechanization filling process, and be one bag of can several seconds.This filling process all requires packaging bag that certain permeability to air will be arranged, but for protection against the tide, the soft lining of currently marketed packaging bag is all airtight, after making the forced draft band of feeding powder or granules to enter the packaging bag bottom, because vapour lock is returned sack again, the lower floor of big portion's powder or the granules sinking bag end or bag, fraction is discharged to outside the bag with being floated to bag top on the air-flow.At present main packaging process has three kinds: first kind is that spacious sack is irritated bag method, when irritating bag big sack is opened wide in packaging bag, carry out after the can envelope again, this uncovered packaging process, can efficient is low, i.e. packaging process and the efficient mechanical production line fast cover that mismatches, part material turns up with air-flow during can, make that dust content of air exceeds standard greatly in the workshop, contaminated environment, it is slow to influence direct labor's health and filling speed; Second kind of packaging process is to adopt between filling exit and the filling bag tubular stinger to leave the gap, allows the air-flow that enters packaging bag discharge from the gap, and this packaging process is more better than first kind, efficient is higher, but still have fraction, raw material overflows with the air-flow of discharging, and pollutes still more serious; The third packaging process is, the exhaust of on the bag wall on bag top, punching, and filling exit is less, with feeding tubular stinger flush fit, this packaging process, because the inlet and outlet overbalance, cause vapour lock bigger, filling speed reduces, packaging bag can deficiency in weight, increase the packaging bag number for replenishing weight, cost further improves again, and simultaneously, powder or granules are also taken out of from the deflation hole on bag top easily, foul air, powder also can release from deflation hole in the transportation.
The composite microporous bag of CN9323137.0 paper has solved the problem of latex glass wool cloth packaging bag cost height and printing quality difference.It is by bonding ply of paper on the plastic woven cloth surface, get the uniform 0.1-0.5mm aperture of several rows as deflation hole on bag filling exit one end top then, the shortcoming that this packaging bag exists is not still eradicated in can and the transportation from deflation hole blowdown problem, and anti-soak properties are low.
The objective of the invention is to reform packaging process, reduce packing cost, develop the self-bleeding function and have degassing function that the packaging bag of moisture-proof function is arranged again simultaneously.
Technical scheme of the present invention is achieved in that a kind of air-flow that adapts to the high speed machine equalization drives powder or granules inlet and outlet automatic balance pouring method, after making air-flow drive powder or granules enter packaging bag from filling exit, the feeding gas that enters in the bag is discharged from embedding is connected in the formed minute aperture of exhaust filter material layer the bag wall, free air capacity is approximately equal to suction quantity, and powder or granules stay and amass in bag.
Self-bleeding is anti-lets out packaging bag, forms by filling exit with the bag that the soft lining of airtight protection against the tide constitutes, and embeds in the bag wall of the top of filling exit one end and is connected with the soft lining of exhaust filter material layer.
Be fixed with the soft lining of airtight moisture proof barrier in the covering of exhaust filter material layer outside.
Cover the soft lining of airtight moisture proof barrier on the exhaust filter material layer, the airtight moistureproof bag soft lining outer with the exhaust filter material layer forms the exhaust passage to be interrupted connection mode.
The positive effect that implements of the present invention, it utilizes the good soft lining advantage of airtight anti-soak properties, utilizing again simultaneously has the soft lining of certain exhaust performance to embed in the bag wall, has solved the exhausting problem when irritating bag, air inlet and exhaust balance, the can weight standard, improve can efficient, in storage and transportation not blowdown, do not waste raw MAT'L, free from environmental pollution, reduce dust content in the workshop air greatly, improve workman's working environment.The airtight moisture proof barrier of one deck is arranged again on the exhaust filter material layer, after can is toppled over, the packaging bag upper air is extruded, the inner negative pressure that forms of packaging bag, at this moment, exhaust filter structure layer and moisture proof barrier tightly stick to one under external atmosphere pressure and the effect of raw material expansion phase, play the moistureproof anti-effect of letting out in storage and the process of transporting out.
