Description

Glass pressing machine

Technical field:

The utility model relates to a kind of glass processing equipment, particularly a kind of rolling press that is used for the simple glass calendering formation.

Background technology:

Rolling press is one of key equipment in the rolled glass production line, is installed in melting furnaces fining end lip tile rear end.Glass metal is parallel in the kiln overflows between two stacks by lip tile, rotates with different linear velocities by two rollers, and glass metal is squeezed into certain thickness glass ribbon, through supporting plate and transition roller platform glass ribbon is transported on the annealing furnace roller-way.The present rolling press that generally uses, most employings are abroad introduced or according to the rolling press of giving information and making, are not had certain standard abroad, and cost an arm and a leg, use the maintenance inconvenience, the glass sheet quality of producing is undesirable, and principal reaction is inhomogeneous and some defective workmanship at thickness of slab.Trace it to its cause, this class stack adopts the sliding friction rotating manner between spindle nose and the copper sheathing more, is carved with oil storage vessel at the copper sheathing internal surface, loads high-temperature lubricating grease or continuously extruded machine oil.The copper sheathing wall thickness that uses is all more than 12mm.Roller spindle nose place working temperature is higher, generally about 200 ℃.And the coefficient of linear expansion of copper sheathing is 17.6 * 10 ^-6/ ℃ (along the sheet metal thickness direction), thermal conductivity is 35W/mk.Roller spindle nose coefficient of linear expansion 13 * 10 ^-6/ ℃.Block in order to prevent to rotate, adopt between roller spindle nose and the copper sheathing bigger tolerance clearance (〉=1.5mm).In this case.Stack is when extruding glass, and the relative temperature of glass liquid of roll surface temperature is lower, causes glass metal cooling suddenly to contact roll surface place crystallization with glass metal, has increased the relative friction forces between roller spindle nose and the copper sheathing, and load pressure also increases thereupon.So in use for some time, the copper sheathing wearing and tearing are bigger, and the gap of corresponding copper sheathing and spindle nose increases.If the temperature of glass liquid instability of extruding, then the glass viscosity increases or reduces, and just might make roller spindle nose bob.The glass ribbon that squeezes out will produce became uneven.For remedying this type of defective, domestic a lot of producers usually adopt the method (generally all more than 300mm) of the diameter that increases stack to increase roller weight.Even Ji Ya temperature of glass liquid when unstable, can not make the roller bob yet in fluctuation range like this.But because the friction of copper sheathing increases, every certain interval of time needs operator to regulate the stack gap, uses comparatively inconvenience.The also corresponding raising of device fabrication cost.In addition, such rolling press is to adopt motor to drive stack by mechanical drive to rotate, so the transmission system instability, also causes the roller transmission accuracy to descend easily, forces roller that periodic jumping phenomena is arranged, and causes the sheet thickness inequality.Extensively retrieve at the problems referred to above, case is put in the solution that still finds no effect.

The utility model content

The purpose of this utility model is improved existing rolling press structure exactly, and its stack transmission accuracy that exists is low to overcome, the spindle nose wearing and tearing are big, the defective of unreasonable structure.

To achieve these goals, the utility model has been taked following technical scheme:

A kind of glass pressing machine, it is by last stack, bottom calender roll, the rod column, supporting plate, the water bag, carrying roller, transition roller, top rack and lower bearing bracket are formed, on, bottom calender roll is installed on the rod column, the rod column is installed on the top rack, top rack is installed on the lower bearing bracket, the water bag hangs and is located on the top rack, supporting plate is installed on water and wraps face, carrying roller, transition roller is installed in the afterbody of supporting plate, improvements of the present utility model are: 1, be respectively equipped with on top rack and the lower bearing bracket and cooperate guide rail and the guide groove that slides, lower bearing bracket is provided with a rhizoid thick stick, connects a pair of gear on the leading screw, each gear respectively be arranged on top rack on tooth bar be meshed.2, connect 2-4 leading screw with bearing on the top rack, connect a pair of nut on each leading screw respectively, connect a studdle on each nut respectively, each hinged water bag supporting seat in screw rod upper end, water bag supporting seat and water bag are affixed.3, described upward stack, bottom calender roll are connected a star coupling respectively with carrying roller, the versatile spindle that each star coupling passes through to be connected links to each other with the star coupling of the other end, and each star coupling of this end connects a frequency conversion direct-coupled electrical machinery speed reduction unit respectively.4, described lower bearing bracket is provided with an oil pump, be respectively equipped with a composite shaft sleeve of forming by copper sheathing and tetrafluoroethylene cover that matches with bearing support on every end spindle nose of last stack, bottom calender roll, be respectively equipped with one group of oilhole on the described bearing support and be communicated with composite shaft sleeve, oil pump is connected with oilhole on the bearing support of every end of last stack, bottom calender roll respectively by affiliated oil pipe.

Advantage of the present utility model is: the composite shaft sleeve that roller spindle nose of the present utility model adopts copper sheathing and tetrafluoroethylene to constitute, its principal feature is that thermal conductivity, coefficient of linear expansion are all less than copper sheathing, and compressive strength is greater than copper sheathing, can oil-free lubricatoin can lubricate by fuel feeding again, and friction and deflection are less, also have only 0.01～0.02mm, it also is very faint that roller surfaces is beated, thereby effectively eliminates the roller influence of this unfavorable factor to quality product of beating.The transmission system system adopts the motor and the step-down gear direct connection of variable frequency control, power is passed to roller by universal coupling, high-precision steady running, save a large amount of electric energy, operator can be by the convenient linear velocity of regulating each roller exactly of frequency-changing control system, guarantees the speed difference ratio between upper and lower, the transition roller.The stack roller diameter reduces to some extent in addition, makes calendering unit compact overall structure reasonable, is convenient to operation, maintenance.And can reduce manufacturing cost.

For the utility model is described in further detail, following accompanying drawing provides the best of the present utility model
