Abstract
The utility model provides a tread rubber evenly stretching device which comprises a machine base, a tire rotating mechanism, a tire lifting mechanism and a press roller, wherein one side of the machine base is provided with an upright column, the tire lifting mechanism is arranged on the upright column, the tire rotating mechanism is mounted on the tire lifting mechanism, and the press roller is mounted at the front end of the machine base and below the tire rotating mechanism. An old tire which needs refurbishment is mounted on the tire rotating mechanism and filled with air; the tire lifting mechanism drives the tire rotating mechanism to move downward to press the front end of tread rubber between the tire and the press roller; the tire is deformed; the tire and the press roller are rotated at the same time; the tread rubber is adhered to the surface of a tire body while maintaining the same tension; redundant tread rubber is cut off and used for gluing of a next tire. The tread rubber evenly stretching device is simple in structure and convenient to operate. Even stretching of the tread rubber is guaranteed due to the fact that the tread rubber wraps the surface of the tire body under certain pressure.
Description
Technical field
The utility model relates to a kind of device that the rubber tyre refurbishment process makes the tread rubber even tension stretch that is used for when the carcass surface adhesion tread rubber of old tire, belong to the tyre retreading technique field.
Background technology
Tyre rebuilding is exactly that the part that is ground off with damaged is handled through special process; Change new rubber combination (tread rubber); Make worn tire become a complete tire; Its technical process generally is earlier that the polishing of old tire crown is extremely best size, will be coated on the carcass surface of the old tire of handling through polishing again through the tread rubber of high-pressure molding, becomes one through sulfuration adhesion.At present generally being through manual work that the carcass that tread rubber is attached to the old tire after polishing is handled is surperficial, is to reduce internal stress, under the tire simulation actual motion condition; Cross dimension with when inflation is fitted with circumferential size, but tire when inflation, circumference becomes greatly; After having pasted the tyre surface exhaust, circumference shrinks again, in order not make tyre surface too lax after the tire exhaust; To such an extent as to can't transmit to next station, tread rubber needs suitably to stretch uniformly to fit.It is inhomogeneous that manual tension causes tread rubber to stretch; Tread rubber after coating like this is at carcass surface quality skewness; Tire self imbalance after the influence renovation, and the inhomogeneous tyre retreading stress distribution that also causes of tensile force is inhomogeneous, has just increased the probability of blowing out during the tire high-speed cruising.
Summary of the invention
The utility model is inhomogeneous to the tread rubber tensile force that exists in the existing tyre rebuilding process, and the problem of non-uniform mass provides a kind of simple in structure, easy to operate, even stretching device in the time of can guaranteeing that tread rubber coats on the carcass surface.
The even stretching device of the tread rubber of the utility model adopts following technical proposals:
The even stretching device of this tread rubber; Comprise support, tyre rotation mechanism, Lifting for tyre mechanism and pressure roller; One side of support is provided with column, and column is provided with Lifting for tyre mechanism, and tyre rotation mechanism is installed in the Lifting for tyre mechanism; Pressure roller is installed in the front end of support, and is in the below of tyre rotation mechanism.
Lifting for tyre mechanism comprises guide rail, slide block and travel mechanism, and slide block is installed on the guide rail, and guide rail is arranged on the column, is connected with travel mechanism between slide block and the column.Travel mechanism can adopt feed screw nut transmission mechanism, hydraulic cylinder, electric pushrod etc.
Rotating mechanism comprises shaft seat, motor, transmission mechanism and rotating shaft, and shaft seat and slide block link together, and is horizontally installed with rotating shaft on the shaft seat, and transmission mechanism is installed on the shaft seat, and its output is connected with rotating shaft, and motor is connected with the input of transmission mechanism.Transmission mechanism can adopt various type of belt drive such as band transmission, chain transmission, gear drive, worm and gear.
Be installed in the tyre rotation mechanism old tire of needs renovation and inflation, make the front end of tread rubber get into pressure roller, Lifting for tyre mechanism drives the tire rotating mechanism and moves down; The front end of tread rubber is pressed between tire and the pressure roller, and tire produces distortion, simultaneously; Tyre rotation mechanism drives tyre rotation; Pressure roller rotates simultaneously, and tread rubber remains on the carcass surface that even stretching is bonded in tire, and unnecessary tread rubber cuts away and is used for next tires and fits.
The utility model is simple in structure, and is easy to operate, through under certain pressure, coating tread rubber on carcass surface, guaranteed that tread rubber evenly distributes on the carcass surface and stretches evenly, has guaranteed the tyre rebuilding quality.
