Description
Technical field
The design is related to all steel load tyre building machine, belongs to rubber mechanical equipment field, more particularly to a kind of tyre surface is defeated
Send device.
Background technology
All steel load tire tread is by extruded compound, the pressure contraction of preceding working procedure tyre surface extrusion line, calender lamination, cooling
The technological processes such as conveying, cut-to-length are process.Tyre surface after processing is put into blinds trolley, and is transported to all steel load wheel
By tyre forming machine, tyre surface is removed by forming operation work from louver vehicle and after turn-over, put to tyre surface feed frame.
About 40 kilograms of the weight of one all steel load tire tread, class's production about 90, artificial carrying labour are strong
Degree is big, and easily damages tyre surface in carrying switching process, causes fitting front tyre roll side, influences tire quality.In addition,
During fitting, because feed frame lacks centering device before fitting, tyre surface device for detecting length, tread joint intervenes dress automatically
It sets, the functions such as laminating apparatus, bonding position, connector and fitting quality, the product stability of manual intervention tyre surface is needed to be difficult to
Ensure.
CN107344423 discloses a kind of tyre surface laminating apparatus, the patent tyre surface translator unit：Double wedge above fluted disc 54
55 push down tyre surface, and servo motor 6 controls the speed of tread conveying device 2, by the relative velocity between synchronous belt 4 and banding drum
It controls tyre surface and is bonded connector.The discovery of tire process is actually done, tyre surface can skid on transmission device, and in addition tyre surface head is same
It walks on band 4, remainder then on tyre surface feed frame, synchronizes and carries speed, and tyre surface feed frame does not have speed at this time, can cause
Tyre surface stretches, and the survey length before stretching is meaningless, cannot achieve tyre surface perfection docking；And existing equipment only to synchronous belt 4 with
Fuzzy explanation has been done in relative velocity matching between banding drum, and non-formulas for calculating cannot accomplish really quantitative control fitting
Connector precision.Part in fixed：It refers only to during tyre surface is centered device 8 calmly on tyre surface feed frame 7 and pressure mechanism is certain
The practical tyre surface that wanders off when avoiding tyre surface from transmitting in degree, which is placed on tyre surface feed frame, will not be completely parallel to feed frame, therefore according to
It can not adjust that its is parallel by vertical direction pressure, then tyre surface fixed length measurement data is absolutely inaccurate.
