The utility model discloses an elastic paper feed belt. The elastic paper feed belt comprises a skeleton layer, sheet layers, buffer layers, adhesive layers and friction layers, wherein the skeleton layer is a middle layer; the sheet layers, the buffer layers, the adhesive layers and the friction layers are respectively arranged at two sides of the skeleton layer outwardly; the skeleton layer comprises activated dacron or an aramid fiber fabric, the sheet layer is made of TPU (thermoplastic polyurethane), TPEE (thermoplastic polyeher ester elastomer) or TPA (terephthalic acid), the connecting end of the paper feed belt is of a tooth structure, the sheet layers are glued in a tooth shape so as to form an annular structure, the buffer layer is made of rubber, the adhesive layer is made of a macromolecule adhesive, the friction layer is made of the rubber, and the outer surface of the friction layer is a smooth surface or a pattern surface. The elastic paper feed belt is not sensitive to environment conditions, has the good flexing effect and high joint force, has no requirement on running direction, and has properties such as good elasticity, wear resistance, flexibility resistance, stability of friction coefficient, good effect in paper feeding, and prolonging of the service life.

Description

A kind of elasticity tapes

Technical field

The utility model relates to a kind of tapes, belongs to printing packaging field of mechanical technique.

Background technology

In recent years, domestic printing packaging industry has been developed all kinds of high-grade printing packaging machinery, as sophisticated equipments such as offset press, paste box machine, binder, paper folders, tapes is its critical component, requirement has the features such as good springiness, coefficient of friction be high, wear-resisting, at work, paper or carton on its transmission plane of multi-ribbon gang conveying complete packing moulding simultaneously.But the nylon base tapes that prior art Central Plains is used exists and occurs the phenomenon of He leaf because ambient temperature and humidity difference causes limit portion, it is short that length dimension when upper machine uses in groups has length to have, paper feeding effect is bad, in recent years especially because transporting velocity improves and the reducing of drive footpath, surface elasticity layer is prone to subdues agingly, causes reduce service life.

Summary of the invention

Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of tapes with stability is provided.

For solving this technical problem, the utility model provides a kind of elasticity tapes, comprise casing play, sheet layer, cushion, adhesive layer and frictional layer, described casing play is intermediate layer, both sides outwards set gradually sheet layer, cushion, adhesive layer and frictional layer, and described casing play consists of terylene or the kevlar fabric through activation processing, and the material of sheet layer is TPU, TPEE or TPA, the connection end of tapes is tooth-shape structure, by sheet layer, carries out the bonding structure that circularizes of profile of tooth.

Described cushion is comprised of rubber, and its thickness is 0.5 ~ 1.0mm, and shore hardness is 70 ~ 90 degree.

Described adhesive layer is comprised of polymer binder.

Described frictional layer consists of rubber, and its thickness is 0.5 ~ 3.0mm, and shore hardness is 50 ~ 70 degree, impact elasticity>=50%, Shao Po that abrasion≤60mm ³.

The outer surface of described frictional layer is shiny surface or patterned surface.

Beneficial effect: casing play of the present utility model is terylene or kevlar fabric, insensitive to environmental condition, because brute force is high, makes the thickness reduction of casing play, is applicable to small-wheel-diameter, subdues effective; Take flute profile joint style, move directionless requirement, piecing strength reaches with the more than 60% of body brute force, there will not be and cause belt earlier period damage because of joint cracking in operation process; Between frictional layer and sheet layer, increased cushion, rubber layer thickness is increased, and increased adhesive layer for improve adhering to brute force, make that elasticity tapes has good springiness, wear-resisting, resistance toly subdues, the performance such as stable friction factor, paper feeding are effective, raising in service life.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure: 1 casing play, 2 sheet layers, 3 cushions, 4 adhesive layers, 5 frictional layers.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is specifically described.

Figure 1 shows that structural representation of the present utility model.

The utility model comprises casing play 1, sheet layer 2, cushion 3, adhesive layer 4 and frictional layer 5, and described casing play 1 is intermediate layer, and both sides outwards set gradually sheet layer 2, cushion 3, adhesive layer 4 and frictional layer 5.

Described casing play 1 is by forming through terylene or the kevlar fabric of activation processing, has that very property is good, fixed stretching strength is high, be not subject to the features such as humiture affects, dimensionally stable.

The material of described sheet layer 2 is TPU, TPEE or TPA, and the performances such as reliable, level and smooth profile of tooth is bonding and powerful can be provided.

Described cushion 3 is comprised of rubber, and its thickness is 0.5 ~ 1.0mm, and shore hardness is 70 ~ 90 degree, plays the effect of supporting belt body, buffering sheet layer 2 and frictional layer 5.

Described adhesive layer 4 is comprised of polymer binder, further strengthens the adhesiving effect between frictional layer 5 and cushion 3.

Described frictional layer 5 consists of rubber, and its thickness is 0.5 ~ 3.0mm, and shore hardness is 50 ~ 70 degree, impact elasticity>=50%, Shao Po that abrasion≤60mm ³, thering is the performances such as good springiness, wear-resisting, stable friction factor, its surface can be shiny surface or patterned surface.

The connection end of described tapes is tooth-shape structure, by sheet layer 2, carries out the bonding structure that circularizes of profile of tooth.

Casing play of the present utility model is terylene or kevlar fabric, insensitive to environmental condition, because brute force is high, makes the thickness reduction of casing play, is applicable to small-wheel-diameter, subdues effective; Take flute profile joint style, move directionless requirement, piecing strength reaches with the more than 60% of body brute force, there will not be and cause belt earlier period damage because of joint cracking in operation process; Between frictional layer and sheet layer, increased cushion, rubber layer thickness is increased, and increased adhesive layer for improve adhering to brute force, and make elasticity tapes there is good springiness, wear-resisting, resistance toly subdue, the performance such as stable friction factor, paper feeding are effective, raising in service life.

The above-mentioned embodiment of the utility model, just illustrates, and is not only, all within the scope of the utility model or the change being equal in scope of the present utility model all by the utility model, surrounded.
