Embodiment 1

[0013] Such as Figure 1 to Figure 3 As shown, a nested joint of an open conveyor belt, the joint is an arrow-tooth shape, its symmetrical addendum angle is 30 degrees, the width L1 of the tooth neck is 1 / 2 of the width L2 of the tooth shoulder, and the length L3 of the joint tooth is equal to the transmission The minimum turning diameter of the belt is proportional; the two ends of the open conveyor belt, that is, the A end and the B end adopt the same toothing method, and the tooth tips of the A end and the B end can be nested one by one. The thickness of the conveyor belt is 2 mm, and the length L3 of the joint teeth is 120 mm. In this embodiment, the material of the conveyor belt is thermoplastic polyurethane, and polyurethane adhesive is first applied on the flanks of the joints between the A end and the B end, then nested, and then cured to complete the joint.

Embodiment 2

[0015] This embodiment is basically the same as Embodiment 1, except that the symmetrical addendum angle is 45 degrees, the tooth neck width L1 is 3 / 4 of the tooth shoulder width L2, the thickness of the conveyor belt is 3mm, and the joint tooth length L3 is 90mm . In this embodiment, the material of the conveyor belt is polyvinyl chloride, and the polyvinyl chloride adhesive is first applied to the side surfaces of the joint teeth of the A end and the B end, then nested, and then cured to complete the joint.

Abstract

The invention relates to a nested joint for an opened conveyer belt. The joint is in an arrow tooth shape, and the symmetrical tooth top angles are 30-60 degrees. The width of a tooth neck is 1 / 4 to 3 / 4 of the width of a tooth shoulder, and the joint tooth length is in direct proportion to the minimum turning diameter of the conveyer belt. The same tooth breaking mode is adopted at the two ends, namely the A end and B end, of the opened conveyer belt, and tooth tips of the A end and B end are staggered and can be nested one by one; and the joint tooth side faces of the A end and B end are coated with adhesives at first, then nested and afterwards solidified, and accordingly connection is completed. The thickness of the opened conveyer belt is not smaller than 0.8mm and not larger than 6mm. The joint can prevent disengaging between teeth in the joint treatment process, and large gaps are avoided; and meanwhile, strength of the conveyer belt at the joint position is improved, and the service life of the conveyer belt is made longer.

Description

technical field [0001] The invention belongs to the technical field of conveyor belt processing, and relates to a nested joint of an open conveyor belt. Background technique [0002] The general light-duty conveyor belt is composed of a fiber fabric core and an elastomer coating. The conveyor belt is usually shaped by opening, and then cut according to the length of the endless belt before splicing. The joint methods include toothed joints, toothed overlapping joints, and parallel lap joints. During the process of joint processing, various joint methods will have various situations such as detachment and large gaps, resulting in joint failure, low joint strength, and unsightly joints, which will cause unnecessary losses. Contents of the invention [0003] The object of the present invention is to provide a nested splice of an open conveyor belt in order to overcome the defects in the above-mentioned prior art, so as to prevent teeth from being separated from each other an...
