Description

Wheel tread trimming production line
Technical Field
The invention relates to tire retreading equipment, in particular to a tire tread retreading assembly line.
Background
Because the air in the mould is exhausted to the outside of the mould in the process that the green tyre is vulcanized into the tyre in the mould, the mould is provided with an exhaust hole, the rubber of the tyre is melted and flows into the exhaust hole during vulcanization, the tyre is gradually cooled after vulcanization is finished, and the 'fluff' is formed when the rubber which initially flows into the exhaust hole is hardened. In fact, all tires have the 'fuzz' which is only scraped off by some manufacturers before the tires leave the factory, so that the tires look neat. Because the tire is formed by processing the mold, the mold is provided with a plurality of small holes for exhausting air, and the tire is heated and vulcanized for a period of time after the mold is closed and pressurized. The rubber slowly softens with increasing temperature and time. When the temperature reaches the viscous flow temperature of the rubber, the rubber can have certain kinetic energy to flow. Some of the rubber will flow out of the vent holes in the mold, forming small burrs. After vulcanization, the final process of tire production is external inspection (namely appearance inspection). In this process, these small portions of the tire are removed.
There is a need for an automated apparatus for trimming rubber burrs on tires quickly and efficiently.
Disclosure of Invention
The invention overcomes the defects of the prior art and provides a tire tread roughening production line.
In order to achieve the purpose, the invention adopts the technical scheme that: a tire tread roughening assembly line comprising: the wool trimming machine comprises a roller shaft conveying line and a plurality of wool trimming stations which are sequentially arranged along the roller shaft conveying line, and is characterized in that each wool trimming station comprises a rotary boss, and at least one wool trimming manipulator is arranged on the outer side of each rotary boss;

In a preferred embodiment of the present invention, the rotating boss is a truncated cone structure, and the rotating boss is driven by a motor to rotate.
In a preferred embodiment of the present invention, the trimming robot is fixedly disposed at an outer side of the roller shaft conveying line.
In a preferred embodiment of the present invention, the roller conveying line is provided with a plurality of rollers arranged in sequence along an extending direction of the roller conveying line, and the axes of the rollers are perpendicular to the extending direction of the roller conveying line.
In a preferred embodiment of the invention, a plurality of cutter heads are vertically stacked together.
In a preferred embodiment of the invention, each cutter head comprises a motor and a cutter connected through a motor rotating shaft, and the cutter can be driven to rotate by a driving motor.
In a preferred embodiment of the invention, the motor comprises a motor body and a knife connected to the motor body; on the cutter shaft, the peripheral dimension of the idler wheel is larger than that of the motor body, and the end part of the trimming knife exceeds the periphery of the idler wheel.
In a preferred embodiment of the present invention, the torsion spring is capable of applying a torsion force to the first ends of the two torsion arms to make the second ends of the two torsion arms close to each other.
In a preferred embodiment of the invention, the tension magnitude and the tension direction of the hair trimming manipulator can be changed by changing the specification of the torsion spring.
The invention solves the defects in the background technology, and has the following beneficial effects:
(1) torsion is applied through the torsion spring, so that the cutter shaft can be tightly attached to the side face of the tire with certain tension, the close contact between the trimming cutter on the cutter shaft and the side face of the tire is ensured all the time, and even when the tire or equipment shakes, the trimming cutter can also perform trimming work. Because there is the decorative pattern on the tire surface, the arbor pastes on the tire, and when arbor and tire relative rotation, the arbor can beat relative tire surface relatively, and tension can guarantee that the arbor pastes tight tire surface.
(2) Two gyro wheels set up at its arbor both ends, have guaranteed that the arbor can keep suitable distance with the tire all the time, make the repairer on the one hand can not be too near in order to avoid damaging tire and repairer from the tire, on the other hand makes the repairer can not be too far away from the tire, reduces the effect of repairing hair. In addition, due to the rolling capacity of the roller, rolling friction can be formed between the cutter shaft and the tire tread, the cutter shaft and the tire can form rolling friction in the process of trimming, and the cutter shaft and the tire are relatively stable in the process of trimming.
(3) The cutter heads which are stacked together can be continuously spliced along the axial direction of the cutter shaft by a proper length, so that the cutter shaft is ensured to be adapted to the width of the side surface of the tire.
(4) Tension applied to the surface of the tire by the trimming manipulator can be changed by replacing torsion springs with different specifications, and meanwhile, if torsion forces of the two torsion springs are different, the angles of the two torsion arms can generate asymmetric inclination, and finally, a cutter shaft generates certain offset, so that the trimming cutter on the cutter shaft can be attached to the surface of the tire at a proper angle.
(5) Rotatory boss passes through motor drive rotation, and the truncated cone structure of rotatory boss can be convenient fix the downthehole in the middle of the tire to it is rotatory to drive the tire, and the roller transmission line can make things convenient for the tire to remove on the rotatory boss. If the rotary lug boss is connected with the lifting device, the rotary lug boss can be lifted to facilitate the clamping of the tire.
