Abstract

The utility model relates to a conveying belt in a field of conveying belts. Two connecting end faces bonding correspondingly at a breaking position of the conveying belt are provided with symmetric and uniform step faces respectively and the two step faces on the two connecting end of the conveying belt are bonded together fixedly after fitting with each other. Seal adhesive tapes are bonded on bonding seams generated after the two step faces bonded with each other on the front side and the back side of the conveying belt. Faces of the seal adhesive tapes bonding with the conveying belt are rubber faces. The length of each of the seal adhesive tapes is 60 to 80 cm. The width of each of the seal adhesive tapes is equal to the width of the conveying belt. And the central lines of the seal adhesive tapes are corresponding to the bonding seams of the conveying belt. The conveying belt can improve the bonding strength of the connecting ends of the breaking position effectively and improve the stretch resisting capacity of the bonding position of the connecting ends, thereby prolonging the service lifetime of the conveying belt correspondingly.

Description

A kind of travelling belt

[technical field]

The utility model relates to the conveyer belt field, especially relates to a kind of travelling belt that can strengthen breaks interface bind strength.

[background technology]

At present; The user of many travelling belts be mostly take the breaks interface of the travelling belt of scrapping because of fracture bonding again; And then through the adhesive tape of sealing that specialty is repaired usefulness the place, slit of bonding generation is sealed, save productive costs sealing the method that reuses after finishing; But; Owing in long-term practical application, find; Seal adhesive tape and have following shortcoming: one, the existing adhesive tape width that seals is narrower, is difficult for comprehensive bonding place, slit that protects the travelling belt interface, thereby can't actv. avoids the quick wearing and tearing of belt interface abutting edge when reusing; Two, the existing adhesive tape cost that seals is higher, if use the too much adhesive tape of sealing that the slit of travelling belt interface is located to carry out bonding protection, concerning requiring cost-effective enterprise, this obviously can't reach its cost-effective purpose again.

[summary of the invention]

In order to overcome the deficiency in the background technology, the utility model provides a kind of travelling belt, and described belt can effectively strengthen the bind strength of fracture interface, and increases the tensile resistence of interface abutting edge, thus the corresponding service life that prolongs travelling belt.

For realizing the foregoing invention purpose, the utility model adopts following technical scheme:

A kind of travelling belt, the corresponding bonding one side of two interface end faces of described belt breaks is respectively equipped with symmetry and uniform cascaded surface, and the cascaded surface of belt two interface end coincide corresponding back fixed bonding together; Be bonded with sealing tape at the belt tow sides because of the sticking commissure that the mutual bonding back of cascaded surface occurs; The bonding one side of described sealing tape and belt is a rubber face, and the length of sealing tape is 60～80cm, and the width of sealing tape equates with the width of belt, and the bonding seam of the corresponding belt of the line of centers of sealing tape.

Described travelling belt, described cascaded surface are provided with 4～5 step surfaces at least.

Described travelling belt, the step surface of least significant end is positioned at the termination portion of the residing belt interface end of this cascaded surface in the described cascaded surface, and the overall length dimension of cascaded surface is not less than the width dimensions of belt.

Described travelling belt, the rubber face thickness of said sealing tape is 3mm.

Described travelling belt, the another side of said sealing tape is made as the twine face, and the number of plies of twine face is 2 layers or 1 layer.

Owing to adopt aforesaid technical scheme, the utlity model has following beneficial effect:

The described travelling belt of the utility model can effectively strengthen the intensity and the tensile resistence that increases travelling belt interface abutting edge of travelling belt interface abutting edge, thereby has prolonged the service life of travelling belt accordingly, and also actv. provides cost savings for the user.

[specific embodiment]

Can explain the utility model in more detail through following embodiment, the purpose of open the utility model is intended to protect all variations and the improvement in the utility model scope, and the utility model is not limited to following embodiment;

In conjunction with accompanying drawing 1 described travelling belt, the corresponding bonding one side of two interface end faces of described belt 1 breaks is respectively equipped with symmetry and uniform cascaded surface 2, and the cascaded surface 2 of 1 liang of interface end of belt coincide corresponding back fixed bondings together; Described cascaded surface 2 is provided with 4～5 step surfaces at least, thereby can be more firm when bonding; The step surface of least significant end is positioned at the termination portion of residing belt 1 interface end of this cascaded surface in the described cascaded surface 2; And the overall length dimension of cascaded surface 2 is not less than the width dimensions of belt 1, thus the further firm intensity of the actv. cascaded surface 2 of having guaranteed 1 liang of interface end of belt after bonding;

Be bonded with sealing tape 3 at belt 1 tow sides because of the sticking commissure that cascaded surface 2 mutual bonding backs occur, promptly protect the interface abutting edge of belt 1 through sealing tape 3; Described sealing tape 3 is a rubber face 4 with belt 1 bonding one side; As required; Can rubber face 4 thickness of sealing tape 3 be made as 3mm, the another side of sealing tape 3 is made as twine face 5, and the number of plies of twine face 5 be 2 layers or 1 layer; Thereby make the thickness of belt 1 interface abutting edge promptly can be not big because of the too thick hardness that causes; Cause the interface abutting edge of belt 1 fatiguability, easy to crack or be prone to impaired phenomenon in use to occur, also can not cause the interface abutting edge of belt 1 in use to occur fracture once more simultaneously because of the too thin toughness of interface abutting edge that causes is not enough because of tensile resistence is not enough;

The length of said sealing tape 3 is 60～80cm; The width of sealing tape 3 equates with the width of belt 1; And the bonding seam of the corresponding belt 1 of the line of centers of sealing tape 3; Be the both sides equal in length that sealing tape 3 is positioned at the bonding seam of 1 liang of interface end termination of belt cascaded surface, 2 mutual bonding back appearance, thereby actv. has been protected the interface abutting edge of belt 1.

Confirm through experimental result; Described travelling belt is after operation three months; Except that normal wearing and tearing, aliquation do not appear in the interface abutting edge of travelling belt, come unstuck, rupture or play the bag phenomenon, and the whole service life of travelling belt is corresponding to have prolonged 3～4 months thereby make.

Carefully do not state part in the above content for prior art, do not state so run business into particular one.
