Tire tread twines unit
Technical field
The present invention relates to produce the equipment of tire, particularly a kind of unit that is used for the tire tread winding.
Background technology
Present tire tread winding production line is glue post or a film of being extruded definite shape by cold feed extruder, enter the adhesive tape of profile shell extrusion certain thickness and width, cool off by chill roll then, the operator is by the adjusting of controller system, the technological parameter that selection edits in advance, adhesive tape is entangled on the setting position of fetus semi-finished product carcass, carries out compacting by the compression roll on the pressing machine.The pressing machine mainly is made up of compression roll and probe, probe is carried out the baseline scan program before twining, and the baseline curve that in computer, draws, the effect of popping one's head in the winding process is that the detection adhesive tape twines the thickness on the fetus semi-finished product, the signal of gathering signal and computer settings is compared, the control compression roll moves, and winds out the tire tread form of setting.Being equipment detects the winding path of fetus by three-dimensional motion utilization probe, and artificial programmed three-D is followed the trail of, and carries out profiling and twines, because the fetus surface is flexible, causes prohibited data detection true; The crown profile of adding green tyres is the non-rectilinear body, and it detects data and has fluctuation; Again since pressing machine pivot in the outside of tire, compression roll action changes constantly, and by detecting data-driven, the control system complexity is difficult to realize accurate TRAJECTORY CONTROL.Therefore cause the sizing material weight that is wound on the tire inaccurate, tire shoulder position bubble is many.The tire product inherent quality that final influence is produced is defective.
Summary of the invention
The object of the present invention is to provide a kind of tire tread to twine unit, adopt this unit, the sizing material weight that is wound on the fetus is easy to be protected, and tire shoulder position bubble is few, and the tire quality of production is excellent, and this unit is convenient to control.
Technical scheme of the present invention is: tire tread twines unit, comprise and extrude molding press device, cooling device, storage device, pressing machine, temperature control system, electric control system, atmospheric control, described pressing machine comprises pressing head section, support and bracket portion and motion base part, the pressing head is packed on the support, and support links to each other with motion base by line slideway; Motion base comprises four layers, ground floor is the revoliving arm that links to each other with support, revoliving arm links to each other with the second layer is rotatable at centre of gyration place, the second layer installs the guide rail jockey, the second layer links to each other by line slideway with the 3rd layer, the 3rd layer of equipped stopping means, the 3rd layer links to each other by line slideway with the 4th layer, and the 4th layer for being fixedly mounted on the guide rail on the ground.
Beneficial effect of the present invention is: because the centre of gyration of this unit pressing machine overlaps with tire section center of arc, compression roll and air bells removing roll are twined around this center rotation, the twining movement track is simply accurate, be convenient to control, the sizing material weight that is wound on the tire is easy to be protected, tire shoulder position bubble is few, and the tire quality of production is excellent; Because the 3rd layer of this unit pressing machine motion base links to each other by line slideway with the 4th layer, can realize a unit for one or more make-up machine, the saving cost.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 twines the elevation of unit for tire tread of the present invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 twines the structural representation sketch of the pressing machine of unit for tire tread of the present invention;
Fig. 4 twines the pressing handpiece structure simplified schematic diagram of unit for tire tread of the present invention.
The specific embodiment
See also Fig. 1, Fig. 2, tire tread of the present invention twine unit comprise install successively extrude molding press device 1, cooling device 2, storage device 3, pressing machine 4, temperature control system, electric control system, atmospheric control.
See also Fig. 3, described pressing machine 4 comprises pressing head 4-1 part, support 4-2 and carriage 4-3 part and motion base part, and pressing head 4-1 is packed on the support 4-2, and support 4-2 links to each other with motion base by line slideway; Motion base comprises four layers, ground floor 4-4-1 is the revoliving arm that links to each other with support 4-2, revoliving arm links to each other with second layer 4-4-2 is rotatable at centre of gyration place, second layer 4-4-2 below install the guide rail jockey, second layer 4-4-2 links to each other by line slideway with the 3rd layer of 4-4-3, the 3rd layer of equipped stopping means in top, the distance that control second layer 4-4-2 moves on the 3rd layer of 4-4-3 is so that improve the stability of pressing head 4-1.The 3rd layer of 4-4-3 links to each other by line slideway with the 4th layer of 4-4-4, and the 4th layer of 4-4-4 is the guide rail that is fixedly mounted on the ground.
See also Fig. 4, described pressing head comprises pressing roller 4-1-1 and air bells removing roll 4-1-2, and described pressing roller is positioned on the air bells removing roll.When beginning to fit, film is sagging naturally, and film can directly be pressed onto on the fetus by pressing roller and air bells removing roll, and is easy to operate, safe and reliable.
Described pressing head also comprises film automatic cutting means 4-1-3 and film stopping device 4-4-4.Have hot cutter to cut, the work compound of pressing roller and film stopping device has improved wrapping machine automation mechanized operation level.
The course of work of the present invention is: the 3rd layer of motion of power drive motion base, realize pressing machine location, and the pressing machine moves to working position from waiting for the position, and realizes mechanical positioning and locking; The second layer motion of power drive motion base realizes the centralized positioning of pressing machine, and the centre of gyration of pressing this moment machine overlaps with tire section center of arc; The gyroaxis of power drive revoliving arm is realized the rotation of pressing head; Adjust the radius of gyration of revoliving arm when power drive ground floor motion, the fetus of pressing different size.When the pressing head motion puts in place, by extruding the adhesive tape that molding press device extrudes constant thickness and width, cool off by cooling device then, the operator is by the adjusting of controller system, the technological parameter that selection edits in advance, make the pressing head do gyration, adhesive tape is entangled on the fetus semi-finished product, carry out compacting by compression roll on the pressing machine and air bells removing roll around fetus section center of arc.
