Description

Technical Field

[0001] The utility model belongs to the technical field of conveyor belts, and in particular relates to a stretch-resistant PVC conveyor belt. Background Art

[0002] Belt conveyors are widely used in agriculture, industrial and mining enterprises and transportation industries to transport various solid blocks or finished items. Conveyor belts can transport continuously, efficiently and at a large angle. Conveyor belts are safe to operate, easy to use, easy to maintain, and have low freight costs. They can also shorten transportation distances, reduce project costs, and save manpower and material resources. Conveyor belts used in existing conveyors are mostly made of PVC material, which have a relatively simple structure and average tensile strength and are prone to breakage. In order to prevent the conveyed objects from sliding, anti-slip strips are designed on the conveyor belts. The anti-slip strips are used for a long time to maintain stress. After a long time, the anti-slip strips will be disconnected from the conveyor belt body and cannot be used normally. In addition, since the current anti-slip strips are generally an integrated structure with the conveyor belt body and cannot be replaced separately, the entire conveyor belt needs to be replaced, increasing the cost of use. For this reason, the utility model proposes a tensile-resistant PVC conveyor belt. Utility Model Content

[0005] A plurality of independent anti-slip baffles are arranged on the rubber layer, and a plurality of mounting holes are opened on each of the anti-slip baffles. A limiting clamping column aligned with the mounting hole is fixedly arranged on the rubber layer as a whole, and the limiting clamping column can move through the corresponding mounting hole, and a pair of limiting buckles are extended from the top end of the limiting clamping column, and the anti-slip baffles are limitedly engaged by the limiting buckles, and an internal thread groove is arranged between the pair of limiting buckles, and a threaded column is screwed in the internal thread groove.

[0006] Preferably, the pair of limiting buckles are in a truncated cone-shaped structure that gradually expands from top to bottom, and the limiting clamp column and the limiting buckle are an integrated structure.

[0007] Preferably, the diameter of the mounting hole matches the diameter of the limiting clamp column, and the maximum diameter of the limiting buckle is 7-8 mm larger than the diameter of the mounting hole.

[0008] Preferably, glass fiber sheets are irregularly mixed in the rubber layer, and a flame retardant and fireproof coating is provided on the top surface of the rubber layer.

[0009] Preferably, the nylon mesh reinforcement layer has a honeycomb structure through the weaving surface.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the utility model designs a conveyor belt with a composite multi-layer structure, which has good tensile resistance, avoids the situation of breakage after long-term use, and improves the stability of the conveyor belt;

[0011] An independent anti-slip baffle is designed, which can be replaced in time if it breaks; and a snap-fit ​​structure is designed so that the anti-slip baffle can be quickly disassembled and assembled, and the broken anti-slip baffles can be replaced one by one, which reduces the cost of use.
