Most of traditional synchronous conveying belts use steel wire ropes or glass fibers as a strong layer, an annular belt made of polyurethane or chloroprene rubber is coated outside the traditional synchronous conveying belts, and the inner periphery of the belt is made into a tooth shape so as to be meshed with a toothed belt wheel. It combines the advantages of belt drive, chain drive and gear drive. When the belt wheel rotates, the belt teeth are meshed with the tooth grooves of the belt wheel to transmit power.

Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

The invention provides a repair and modification process of a conveyor belt, which is used for repairing an annular conveyor belt with a strong layer and internal teeth. The annular conveying belt is a synchronous conveying belt made of silica gel, rubber or PU materials, and the strong layer is a steel wire rope layer or a glass fiber layer compounded in the synchronous conveying belt; the internal tooth is a trapezoidal tooth with a certain width on the bottom surface.

As shown in fig. 1, the repair and retrofit process mainly comprises three steps: step1, removing worn internal teeth, step2, adding metal internal teeth, and step3, adding a baffle. Wherein, the step2 and the step3 are not in sequence and are selected according to actual needs.

Referring to fig. 2, in the step of removing worn internal teeth in step1, the worn internal teeth on the annular transmission belt 1 are completely removed to obtain a surface to be repaired 2 which is flush with the bottom surfaces of the teeth. The worn internal teeth are removed by grinding with a grinding wheel or cutting with a cutter.

Referring to fig. 3 and 4, in the step of adding the metal internal teeth in step2, firstly, a plurality of first mounting holes 3 penetrating through the annular conveyor belt 1 are formed in the surface 2 to be repaired, then metal internal teeth 4 and baffles 5 are respectively arranged on the inner side and the outer side of the annular conveyor belt 1 corresponding to the surface 2 to be repaired, and the metal internal teeth 4 and the baffles 5 are fixed on the annular conveyor belt 1 together by bolts or screws 6 penetrating through the first mounting holes 3.

In the step3 of adding the baffle, the baffle is basically added in the same way as the step of adding the metal internal teeth, but is added on the unworn internal teeth. The method comprises the steps that a plurality of second mounting holes penetrating through an annular conveying belt and blind holes arranged around the second mounting holes and communicated with the second mounting holes are formed in the unworn internal teeth, metal pieces are filled in the second mounting holes and the corresponding blind holes, baffle plates are arranged on the outer sides of the annular conveying belt corresponding to the unworn internal teeth, and the metal pieces and the baffle plates are fixed to the annular conveying belt together through bolts or screws penetrating through the second mounting holes.

In this embodiment, the blind holes are provided to make the connection strength between the metal member and the endless belt stronger. The blind hole is preferably a kidney-shaped hole, and the shape of the metal piece 7 is shown in fig. 5. Obviously, in other embodiments, the blind hole may be a circular hole, an elliptical hole; similar effects can be achieved.

It should be noted that step 3) is set as required, and in some embodiments, step 3) may be omitted. After the steps 1) and 2) are finished, if the number of the baffles is still insufficient, the operation of the step 3) can be added according to the requirement.

Referring to fig. 6 and 7, a connecting piece 4-1 matched with the corresponding first mounting hole 3 is integrally formed on the metal inner teeth 4, and a screw hole 4-2 matched with the bolt or screw 6 is formed in the connecting piece 4-1. For the convenience of processing, the screw hole is preferably a through hole, and when the bolt or the screw 6 is arranged, the head of the bolt or the screw is not required to penetrate out of the through hole. Of course, in some embodiments, the screw holes may be provided as blind holes.

Similarly, a connecting member that engages with the corresponding second mounting hole is also integrally formed on the metal member 7, and a screw hole that engages with the bolt or screw is formed in the connecting member. The arrangement of the connecting pieces and the screw holes on the metal piece 7 is basically the same as that of the connecting pieces and the screw holes on the metal internal teeth, and the description is omitted here.

In this embodiment, the metal internal teeth, the metal piece and the metal baffle are all stainless steel pieces, have certain intensity and are not easy to wear. In some embodiments, the metal inner teeth, the metal piece, and the metal baffle may be an aluminum alloy piece or a copper alloy piece; the present embodiment is not limited.

Referring to fig. 8, the baffle 5 includes a mounting surface 5-1 and a blocking surface 5-2 extending in a direction perpendicular to the mounting surface 5-1, the mounting surface 5-1 is attached to an outer side surface of the endless conveyor 1 for connecting the bolts or screws, and the blocking surface 5-2 is planar or arc-shaped and is used for pushing an article to be conveyed.

In this embodiment, preferably, the mounting surface 5-1 is provided with a stepped hole 5-3 matched with a bolt or a screw, and after the bolt or the screw is assembled in place, a nut of the bolt or the screw is hidden in the stepped hole 5-3, so that the mounting surface is more attractive, and unnecessary blocking of conveyed articles is avoided.

Referring to fig. 9, the connecting member 4-1 penetrates through the corresponding through hole and protrudes out of the annular conveyor belt 1, and a hole (such as the stepped hole 5-3) matched with the connecting member 4-1 is formed in the mounting surface 5-1; the metal inner teeth 4 and the baffle 5 are assembled and limited through the connecting piece 4-1 and the hole positions. Similarly, the metal piece and the baffle 5 are also assembled and limited through the corresponding connecting piece and the hole position. Therefore, the assembly strength among the annular conveyor belt, the metal inner teeth/metal piece and the baffle can be effectively improved.

Referring to fig. 10, two adjacent baffles 5 are arranged at equal intervals, and the blocking surface 5-2 is arc-shaped. Therefore, the cylindrical articles can be stably conveyed, and the conveying effect of the articles is effectively improved.
