Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of roller table machine, concretely relates to a single motor double-station continuous power turnover roller table machine with external support. BACKGROUND

[0002] Under the background of the rapid development of the logistics industry in China, various industries have higher requirements for the efficiency, stability and reliability of material conveying. Turnover roller table machine, as a key equipment for material conveying, is widely used in many fields. The traditional single motor single-station roller table machine has relatively light load in the process of material conveying due to its single-station design. In terms of structure, only oil cylinder support is needed, and the force borne by the rear support is small, so the fixing bolts are not easy to loosen. At the same time, the oil cylinder is symmetrically supported on both sides, which greatly limits the shaking of the roller table machine during operation, ensuring that the roller table machine can stably convey materials.

[0003] However, with the expansion of production scale and the increasing complexity of material conveying demand, double-station turnover roller table machine emerges as the times require. Although this double-station equipment significantly improves the conveying capacity of materials, it also brings a series of problems to be solved. First of all, due to the need to convey more materials at the same time, the conveying weight increases significantly, and the rear support needs to bear more force, resulting in an increase in the stress of the expansion bolts of the connecting parts. In the long-term use process, the risk of bolt loosening increases significantly. Secondly, the double-station design greatly increases the width of the roller table machine. If the traditional double-oil cylinder support method is still used in the middle, the roller table machine is prone to tilting during material transportation, which not only affects the normal conveying of materials, but also may cause damage to the conveyed materials.

[0004] In view of the above problems, the researchers urgently need a double-station continuous power turnover roller table machine that can effectively reduce the stress on the rear legs, improve the stability of the equipment and maintain the stable transportation of the roller table machine.
