Abstract

A kind of method of surface treatment in glass bottle just when bottle-making machine is exported, is promptly thrown in a granose ammonium sulfate pulvis at vial in bottle, then vial is sent into annealing furnace annealing.The automatic powder supply machine that provides according to this method comprises hopper, material storage pipe and blanking mouth, and adopts the reciprocal piston rod that is provided with feedhole of horizontal slip, the pulvis in the material storage pipe is quantitatively imported blanking mouth fall in the vial.The present invention is because input pulvis is evenly distributed in the bottle, thereby bottle absorbs heat evenly at an end everywhere, reduced the generation of crackle, improved the processing quality, also saved facility investment and raw materials consumption, reduced operator.

Description

Method of surface treatment in glass bottle and automatic powder supply machine

The present invention relates to a kind of method of surface treatment in glass bottle and equipment thereof.

Existing method of surface treatment in glass bottle is when the firm moulding of glass, drops into the ammonium sulfate treatment agent in bottle, then bottle is sent into the annealing kiln annealing.Make ammonium sulfate under annealing temperature, generate one deck than the more stable top layer of traditional boracic infusion bottle chemical property with the interior surfaces of glass reaction.This is particularly suitable to all kinds of infusion bottles and food-bottle.What but the input bottle was interior in the past all is the tablet of single particle.Owing to always concentrate on certain a bit after the ammonium sulfate of single particle enters in the vial.When its when gasification of being heated, taken away a lot of heats in this point zone, the inhomogeneous contraction of glass produces internal stress, thereby make glass surface generation tiny crack in various degree, even bottle is broken at the bottom of causing bottle.In addition since the ammonium sulfate specific gravity of gas less than air, the gas diffusion of must rising after its gasification.Certain gas that a bit gasifies obviously is difficult to all diffuse to total inner surface in the bottle.Thereby ammonium sulfate gas to contact obviously be uneven (referring to Fig. 3) with a bottle internal surface, naturally influence handle quality moreover, because the corrodibility of ammonium sulfate is very strong, make in the process of tablet, the oxide compound that produces after the pelleter mould contacts is with it brought in the bottle with tablet easily, and this is unallowed concerning infusion bottle.And existing way also need increase the film-making operation one, increases investment, equipment and operator etc.Because the specification of bottle is a lot, thereby the mould of pelleter also need be more, and cost is increased thereupon.

The objective of the invention is to overcome above-mentioned the deficiencies in the prior art part, provide a kind of and improve one's methods and equipment, in the hope of reaching less investment, materials are economized, the characteristics that quality product is good again.

The present invention is by the following technical solutions:

Moulding just in vial when bottle-making machine export, is still thrown in an ammonium sulfate treatment agent in bottle, then vial is sent into annealing furnace and annealed.But what throw in each bottle is not the ammonium sulfate tablet of single particle, but granose ammonium sulfate pulvis.Particle grain size is generally greater than 160 orders.

Automatic powder supply machine device the defeated bottle band place bottle-making machine and annealing furnace between designed according to aforesaid method is provided with hopper, material storage pipe and blanking mouth above defeated bottle band.Hopper directly communicates up and down with material storage pipe, material storage pipe and blanking ozzle then mutually stagger up and down and accompany between the two one can under electro-magnet and the returning spring effect, level reciprocatingly slides on the flat board fixed piston rod, be shaped on a feedhole on the piston rod.Piston rod reciprocatingly slides each time, and this feedhole all respectively is communicated with once with material storage pipe and blanking mouth respectively.The both sides of defeated bottle band also are equipped with and can be sent signal projector and the receptor that signal makes the electro-magnet action.

Further specify below in conjunction with embodiment shown in the drawings

Fig. 1 is the structural representation of automatic powder supply machine.

Fig. 2 is the enlarged diagram at blanking mouth position.

Fig. 3 is the vaporized state synoptic diagram of single particle ammonium sulfate tablet in vial.

Fig. 4 is the vaporized state synoptic diagram of many ammonium sulphate grains pulvis in vial.

This structure of throwing the powder machine is by Fig. 1, shown in Figure 2.Hopper 10 directly communicates with material storage pipe 1.Material storage pipe and blanking mouth 4 then stagger mutually, and accompany between the two one can level reciprocatingly slides under electro-magnet 9 and returning spring effect piston rod 3, piston rod is provided with a feedhole.Fixing one flat plate also under the piston rod also has a hole on the flat board, this hole just in time communicates with blanking mouth.When being placed with pulvis in the feedhole, owing to there is flat board to entrust, pulvis can not fall.Have only the feedhole of working as and blanking mouth on time, the pulvis in the feedhole just can fall into blanking mouth by the hole on the flat board.When piston rod resetted under the returning spring effect, feedhole just in time communicated with material storage pipe, and the pulvis in the material storage pipe just falls into and fill up feedhole.Work as piston rod movement, when feedhole is removed material storage pipe, because the lower end outlet of material storage pipe has been closed in the piston rod blocking-up, so the pulvis in the material storage pipe no longer falls.Piston rod is moved to the left a segment distance under the electro-magnet effect, feedhole is then just in time aimed at blanking mouth top, and the pulvis in the feedhole just all falls, and enters in the vial by blanking mouth.The size of conversion feedhole can be regulated the quantity that enters the treatment agent in the bottle, to adapt to the needs of different size bottle.It is its cross section that vial 5 is with 6(shown in Figure 1 by the defeated bottle of bottle-making machine.The direction of motion of this band is perpendicular to this Fig. 1 paper) deliver to below the blanking mouth, when bottleneck is just in time aimed at blanking mouth, signal transmission between signal projector 8 and the receptor 7 is also just in time blocked by bottle, so electro-magnet 9 energising actions, just motion (direction is shown in the arrow among Fig. 1) of piston rod 3, quantitative feed once.Electro-magnet discharges then, piston rod reset under the returning spring effect (the back material storage pipe that resets just in time communicates with feeding tube, and toward the feedhole feeding).A loop ends (the 2nd, support).

The treatment process of using the present invention to propose, the state because granose ammonium sulfate pulvis is evenly distributed after falling in the vial to absorbing heat at the bottom of the bottle evenly, thereby has reduced the generation of crackle everywhere during the pulvis gasification.And in the bottle ammonium sulfate gas that produced can with the internal surface of bottle fully, contact (shown in Figure 4) uniformly, the processing quality is improved greatly.In addition, the ammonium sulfate treatment agent no longer needs film-making, has not only stopped the mould oxide compound and has entered the interior possibility of bottle, has guaranteed the quality of infusion bottle, and has saved facility investment and raw-material consumption, has reduced operator.Automatic powder supply machine reliable operation provided by the present invention, quantitatively accurately, be active in one's movements, structure is also simple, maintaining is also convenient.
