Abstract

The utility model relates to the field of embossing devices, and particularly discloses a medium-high embossing rubber covered roller. The medium-high embossing rubber covered roller comprises a roller body and installing shafts arranged at two ends of the roller body. The surface of the roller body is arranged to be in a parabola shape, and the whole roller body is in the shape that the middle of the roller body is big and the two ends of the roller body are small. The surface of the roller body is further evenly provided with a plurality of adhesive tape. According to the medium-high embossing rubber covered roller, the design of big middle and small two ends is adopted, the section of the roller body is designed to be in the parabola structure, and therefore the appearance is attractive, deformation cannot occur easily under radial pressure, and product quality can be ensured to a certain extent.

Description

Middle high type embossing rubber roll

Technical field

The utility model relates to the Embosser field, relates in particular to a kind of middle height type embossing rubber roll.

Background technology

Calender (calender) is by two or more rollers, pressing certain forms arranges, at a certain temperature, rubber or plastics compacting extension is become the film of certain thickness and surface configuration, and can carry out to fibre curtain canvas or wirecord fabric the mechanical device of kiss-coating.

As everyone knows, calender plays a part very important in the plastic sheeting manufacturing, belongs to the large-scale key equipment of film production.Wherein, the stack of calender belongs to vitals, can the plastics of high temperature be rolled.Dandy roll in the casting films calender device of the prior art generally all adopts cylindrical, its product two ends delustring is better, the centre is slightly poor, the dandy roll of this set not only outside impression is relatively poor, and after being subject to radial pressure, the easily inhomogeneous distortion of its surperficial rubber colloid, the quality of product is made in impact.

The utility model content

The purpose of this utility model is, proposes a kind of middle high type embossing rubber roll, and it adopts parabola shaped structural design small in the end and big in the middle, not only has better outside impression, and is difficult for producing distortion.

For achieving the above object, the utility model provides a kind of middle high type embossing rubber roll, comprises roll body and is located at the installation shaft at roll body two ends, and described roll body surface is the parabolic type setting, roll body is shape small in the end and big in the middle, also evenly is provided with several adhesive tape on this roll body surface.

Wherein, described roll body comprises a mandrel and is sheathed on the roller in the mandrel outside, and several adhesive tape uniform ring is located on this roller surface.

Especially, the roller in the utility model is shape small in the end and big in the middle, and this roller surface is the parabolic type setting.

This roller can adopt aluminum alloy materials to be made.

Described adhesive tape can adopt silica gel material to be made.

Middle high type embossing rubber roll of the present utility model, it adopts shape design small in the end and big in the middle, and the roll body cross section is the parabolic shaped structure design, profile is comparatively attractive in appearance, and when being subject to radial pressure, be difficult for producing distortion, can guarantee to a certain extent product quality.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the structural representation of a kind of specific embodiment of middle high type embossing rubber roll of the present utility model;

Fig. 2 is the mounting structure schematic diagram of a kind of specific embodiment of middle high type embossing rubber roll of the present utility model.

The specific embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1, the utility model provides a kind of middle high type embossing rubber roll, it comprises roll body 10 and is located at the installation shaft 20 at roll body 10 two ends, described roll body 10 surfaces are the parabolic type setting, roll body 10 is shape small in the end and big in the middle, also evenly is provided with several adhesive tape (not shown) on these roll body 10 surfaces.The utility model adopts roll body 10 shapes of this particular design, not only has better outside impression, and when roll body 10 was subject to radial pressure, roll body 10 and the adhesive tape on it can not produce distortion yet, can guarantee to a certain extent the quality of product.

In the utility model specific embodiment, described roll body 10 comprises a mandrel 12 and is sheathed on the roller 14 in mandrel 12 outsides, and several adhesive tape uniform ring is located on these roller 14 surfaces.The compactness setting of this several adhesive tape has higher coefficient of friction, so its flattening ability is stronger, can effectively eliminate the fold that casting films is in operation and produces, guarantee the flatness of film, the film finished product that not only makes has better outward appearance, and serviceability is better.Especially, the roller 14 in the utility model is shape small in the end and big in the middle, and these roller 14 surfaces are the parabolic type setting.In the utility model specific embodiment, described roller 14 can adopt aluminum alloy materials to be made.Because aluminum alloy materials density is lower, intensity is higher, comparatively approach or surpass the high-quality steel, so it is moulding better, has good electric conductivity, thermal conductivity and corrosion stability.In addition, in other specific embodiment of the utility model, can also select common roller material of the prior art to make.As a kind of preferred embodiment of the present utility model, described adhesive tape can adopt silica gel material to be made.Because silica gel is a kind of high activity sorbing material, its water insoluble and any solvent, nonpoisonous and tasteless, stable chemical nature, except highly basic, hydrofluoric acid, do not react with any material, the chemical composition of silica gel and physical arrangement have determined that it has many other same type of material and is difficult to replace to get characteristics: absorption property is high, Heat stability is good, stable chemical nature, higher mechanical strength etc. is arranged.

As shown in Figure 2, middle high type embossing rubber roll 30 of the present utility model is when concrete the use, installation shaft 20 by two ends is installed on the casting machine 40, high type embossing rubber roll 30 is spent rod 42 relative level settings with the calendering on the casting machine 40 in being somebody's turn to do, and also is provided with a cooling and shaping roller 44 in these curtain coating flower rod 42 rear ends.As a kind of preferred embodiment of the present utility model, can also in this, one chill roll 46 be set high type embossing rubber roll 30 front ends, the casting films green compact at first pass through this chill roll 46, then after spending rod 42 calendering formations by middle high type embossing rubber roll 30 with calendering, by behind cooling and shaping roller 44 cooling and shapings, import in lower one technological process and go at last.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
