Rolling connecting package glue supplying system pressure constant glue vat

Technical field

The utility model relates to the tobacco machine structure technology, and particularly cigar mill's cigarette bag is concentrated for colloid system.

Background technology

In the production of cigarettes of cigar mill, need a large amount of white glues.White glues is a polyvinyl acetate emulsion, and cigarette is faintly acid with white glues, and pH value generally between 3～7, has corrosivity to ordinary metallic material; White glues has bigger viscosity, stronger adhesive force, and its viscosity is generally at 750～6500cp; Contain organic solvent and water in the white glues, when white glues was exposed in the air, solvent in the white glues and water can very fast volatilizations, thereby make white glues dry and hard; It is fast more that temperature area high more, that contact with air is big more, air flows, and its dry and hard speed is fast more.

At present, cigar mill's cigarette bag production line is being continued to use the original method of manually sending glue always.Because original adhesive storing box is non-closed container on the cigarette chartered plane group, so, need regularly adhesive storing box to be cleaned.A large amount of white glues are bonded in the wall of adhesive storing box, bring difficulty to cleaning, and the cleaning frequency, to wash difficulty big more in the Changqing more.During cleaning in the container remaining white glues outwelled in vain, both caused a large amount of wastes of white glues, polluted environment again.The installation site of first wife's adhesive storing box is higher on the unit, and far away from operating surface, and general one barrel of white glues weight gives adhesive tape inconvenience at 15～30kg, in when falling glue, is easy to white glues is splashed on unit and ground.In order to alleviate working strength of workers, to reduce white glues between the cigarette hired car and the pollution of water environment, improve cigarette bag Production Line managerial skills, press for a kind of can be with the equipment that white glues is concentrated, automatic transport is supplied with each cigarette chartered plane group.Because white glues viscosity is big, it is dry and hard to be easy to, and has corrosivity, therefore, white glues must be under closed environment, adopt high-pressure delivery, and conveying equipment must be anticorrosion.

Cigarette chartered plane group is made of cigarette machine, spicing machine, bundling press and bar chartered plane, usually cigarette, connect mouth, parcel and bar bag and have nothing in common with each other with white glues.At cigarette bag production line, between 10～20, single consumption of planting white glues is between 0.02～0.10L/min usually for cigarette chartered plane group, if an a kind of white glues of unit adopts a supply unit, to make conveying equipment become numerous and jumbled, and make the workshop pipeline be difficult to arrange.Therefore, white glues is carried must adopt to concentrate and is carried, the average discharge that white glues is carried must be greater than 0.2～1.0L/min, be generally the rhythm of production that satisfies under the various situations, the feed flow of actual white glues is set in 1.0～5.0L/min, because the drag effects of conveyance conduit need to adopt high moulding pump to carry white glues, and the white glues of high-pressure delivery can not mate with the pressure of unit glue consumption and permission.In order to cushion white glues flow and pressure, avoid the numerous starting of high moulding pumping frequency, each the confession glue point that is necessary for every unit provides the buffer control unit of a white glues.

The utility model content

The utility model purpose is to provide supporting rolling connecting package glue supplying system pressure constant glue vat for buffer control unit.

The utility model by cylinder sleeve, be connected the forward and backward end cap at cylinder sleeve two ends and the piston that is engaged in the cylinder sleeve inner chamber is formed, drive end bearing bracket is provided with the glue hole that is communicated with the cylinder sleeve inner chamber, this glue hole is provided with the Jiao Lu connectivity port in the drive end bearing bracket outer end, and in the drive end bearing bracket end steam vent that is communicated with the cylinder sleeve inner chamber is set; Be provided with the passage that is communicated with the cylinder sleeve inner chamber on rear end cap, the outer end of this passage is provided with the gas circuit connectivity port; Described piston is made up of two cock bodys along its length direction, arranges magnet ring between two cock bodys, fixes two magnetic switch in the cylinder sleeve outside along the cylinder sleeve length direction.

The utility model is separated into glue chamber and air cavity by piston with the cylinder sleeve inner chamber, when white glues during through the glue hole of drive end bearing bracket, by the glue chamber of logical glue road pressure piston front end, the air cavity direction of piston moves, when piston during near rear end cap, and the magnet ring magnetic field penetration cylinder sleeve on the piston, make near the magnetic field intensity of a magnetic switch that is positioned at the cylinder sleeve outside reach enough numerical value, and trigger the magnetic switch action, at this moment, white glues is full in the system validation glue cylinder, close into glue valve, stop into glue.When the cigarette bag needs white glues, open the plastic emitting valve that is connected on the glue hole, compressed air promotes piston, the extruding plastic emitting, when piston was pushed to certain position, the magnet ring on the piston made another magnetic switch action in the cylinder sleeve outside, starved in the system validation glue cylinder, system continue as it for glue.This matched with devices is in the colloid system, and white glues is in cylinder sleeve and air insulated, avoided volatilization, dry and hard phenomenon, improves packing and send the glue automatization level.

For fear of the erosion of white glues to magnet ring, the utility model is provided with sealing ring respectively on the cock body of the two side ends of magnet ring.

In addition, the utility model is arranged the pull bar with the cylinder sleeve axially parallel between forward and backward end cap, be used for two end caps at cylinder sleeve two ends are tightened together on the one hand, be used for fixing magnetic switch on the other hand, the position that magnetic switch is fixed on the pull bar can be adjusted arbitrarily as required, thereby is met the upper and lower liquid level that system needs.
