Abstract
The invention relates to a compression roller for locating and laminating a reinforcing bar and a transition layer in an inside liner of a tyre. The compression roller is characterized by comprising two short rollers which are arranged on two independent roller frames, the lengths of the short rollers are greater than the width of the reinforcing bar and are less than one second width of the transition layer. The compression roller provided by the invention is simple in structure and convenient to modify, the reinforcing bar and the transition layer can be located and laminated by adopting the compression roller, the short rollers can be functioned on the reinforcing bars better, and a middle high point of the transition layer can be just prevented by a gap between the two short rollers, so that pressure can be focused on the reinforcing bar; furthermore, the compression roller is made from a wearable hard rubber and plastic material, the problem that the uncompaction is caused by the surface abrasion deformation of the compression roller can be prevented, bubbles at the side of the reinforcing bar can be effectively reduced, the product quality can be improved, and the rework can be reduced.
Description
Technical field
The present invention relates to a kind of tire liner production pressure roller, specifically a kind of tire liner MR medium reinforcing bar and transition zone locate laminating pressure roller, belong to tyre production manufacturing technology field.
Background technology
Tire liner generally includes basic unit, finishing strips 2 and transition zone 3.During production, basic unit, finishing strips 2 and transition zone 3 extrude die mould respectively by machine, are first fitted on transition zone 3 two finishing strips 2 location, and then with basic unit's centering compound, wait to batch after cooling and deposit.In above process, article two, finishing strips 2 is fitted with the location of transition zone 3 needs to use pressure roller, existing pressure roller be one across the long roller 1(at two finishing strips and transition zone see Fig. 1), as can be seen from Fig. 1, the force part of this long roller 1 is mainly at the high some place, centre of two finishing strips 2 and transition zone 3, after running after a while, the superficial layer sclerosis at the long roller 1 stress point place that parts surface high temperature can make, follow the string, force part produces and inside contracts depression (see Fig. 2), the place of depression is pressed unreal thus causes finishing strips 2 edge to occur bubble, both product quality was affected, produce the symptom such as tyre cavity bubble, a large amount of parts are made again to need to do over again, waste time and energy.
In order to head it off, the structure for finishing strips 2 and transition zone 3 had adopts hard material to make the pressure roller of shape as Fig. 2, makes pressure roller can lamination reinforcement bar completely.This creates again a new problem: because the finishing strips width of different types of tyres inner liner, spacing are not identical, if adopt this scheme, just mean that this need make the pressure roller of corresponding different size for different size.Just be equivalent to the pressure roller wanting disposable buying tens kinds of different models.And change a kind of product specification and will change a kind of pressure roller, not only lose time but also increase employee work amount.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of tire liner MR medium reinforcing bar of improvement and transition zone to locate laminating pressure roller, its structure is simple, transformation is convenient, effectively can reduce finishing strips edge bubble, improve the quality of products, minimizing is done over again.
According to technical scheme provided by the invention: tire liner MR medium reinforcing bar and transition zone locate laminating pressure roller, it is characterized in that: comprise two short rollers, two short rollers are arranged on two independently in roll stand, and the length of short roller is greater than the width of described finishing strips and is less than 1/2nd width of described transition zone.
As a further improvement on the present invention, described short roller surface is straight cylindrical surfaces.
As a further improvement on the present invention, two described short rollers are coaxially arranged.
As a further improvement on the present invention, described short roller adopts abrasion-resistive hard material to make.
As a further improvement on the present invention, described abrasion-resistive hard material comprises hard rubber and plastic.
the present invention compared with prior art, has the following advantages:structure of the present invention is simple, transformation is convenient, and adopt this pressure roller finishing strips and transition zone to be located and fit, short roller can act on finishing strips better, the gap left between two short rollers avoids the high point in centre of transition zone just, and pressure is more concentrated on finishing strips; And pressure roller adopts abrasion-resistive hard material to make, and it also avoid the unreal problem of pressure that roller surface abrasion deformation causes, effectively can reduce finishing strips edge bubble, improve the quality of products, minimizing is done over again.

Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 3, Figure 4, pressure roller in embodiment is used for tire liner MR medium reinforcing bar 2 and fits with the location of transition zone 3, it forms primarily of two short rollers 4, two short rollers 4 are arranged on two independently in roll stand, and the length of short roller 4 is greater than the width of described finishing strips 2 and is less than 1/2nd width of described transition zone 3.Such short roller 4 can act on finishing strips 2 better, and the gap left between two short rollers 4 avoids the high point in centre of transition zone 3 just, makes pressure more concentrate on finishing strips 2, improves location laminating effect.In the embodiment of the present invention, the width of described finishing strips 2 is 126mm, and the width of transition zone 3 is 570-790mm, and short roller 4 length is 200mm.
As shown in Figure 3, Figure 4, in the embodiment of the present invention, described short roller 4 surface is straight cylindrical surfaces, can apply pressure to better finishing strips 2 like this, ensure that finishing strips 2 and transition zone 3 locate effect of fitting.Two described short rollers 4 are coaxially arranged, are convenient to the uniformity that operation controls.Described short roller 4 adopts abrasion-resistive hard material such as hard rubber and plastic to make, and can avoid the unreal problem of pressure because roller surface abrasion deformation causes.
Although the present invention's structure is simple, practical effect is very good.Long roller replacement cost is in the past up to 1200 yuan/root, and it is high to change the frequency, and every month will change twice.After improvement, short roller cost is lower, and the replacement cycle is long, as long as change once at most every month.But improve larger benefit and be the reduction of doing over again of inner liner, the inner liner rework cost of our company is about 700 yuan/ton, by daily output 5000 calculating, 7(wall scroll inner liner quality) × 5000(the daily output) rework rate that reduces of × 3.4%() × 0.7(rework cost)=833 yuan/day, can monthly save 24990 yuan/month, so not only greatly reduce the loss of material, the energy, manpower, improve output, most importantly the quality of effective improving product.
