Abstract
The utility model relates to a reinforcement strip share compression roller with transition layer locating pasting in tire liner, its characterized in that: including two short rollers, two short rollers are installed on two independent roller framves, and the length of short roller is greater than the width of reinforcement strip just is less than the half width of transition layer. The utility model discloses simple structure, it is convenient to transform, adopts this compression roller to close the reinforcement strip with transition layer locating pasting, and on the short roller can be used in the reinforcement strip better, middle the culmination of transition layer had been avoided just in the clearance of leaving between two short rollers, and messenger's pressure more concentrates on on the reinforcement strip, and the compression roller adopts wear -resisting stereoplasm rubber and plastic material to make, the unreal problem of pressure of also having avoided presser roll surface wear deformation to cause can effectively reduce reinforcement strip limit portion bubble, improves product quality, and the reduction is done over again.
Description
Technical field
The utility model relates to a kind of tire liner production pressure roller, and specifically a kind of tire liner MR medium reinforcing bar and transition zone locate laminating pressure roller, belongs 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 purpose of this utility model is to overcome the deficiencies in the prior art, and 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.
Technical scheme according to the utility model provides: 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 further improvement of the utility model, described short roller surface is straight cylindrical surfaces.
As further improvement of the utility model, two described short rollers are coaxially arranged.
As further improvement of the utility model, described short roller adopts abrasion-resistive hard material to make.
As further improvement of the utility model, described abrasion-resistive hard material comprises hard rubber and plastic.
the utility model compared with prior art, has the following advantages:the utility model structure 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 utility model is described in further detail.
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 utility model embodiment, 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 utility model embodiment, 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 utility model 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.
