Description

Technical Field

[0001] The present application relates to the technical field of roller conveyors, and in particular to a roller conveyor brake mechanism. Background Art

[0002] At present, during tire processing, roller groups are often used to transport the processed tires. After the tires are vulcanized in the all-steel hydraulic curing machine, the tire unloading robot is used to place the tires on the tire unloading roller for cooling, and the tires are transported to the main conveyor belt before the next mold tire is vulcanized.

[0003] For example, the Chinese utility model patent with patent publication number CN215158047U includes a support frame, a mounting frame arranged on one side of the support frame and a pushing assembly, a conveying member 1 is installed on the upper end of the support frame, a conveying member 2 with a stagnation brake function is installed on the upper end of the mounting frame, a detection module is provided between the conveying member 1 and the conveying member 2, the conveying member 1 includes a transmission plate 1 arranged above the support frame, and the conveying member 2 includes a transmission plate 2 inclined above the mounting frame. What is different from the traditional tire unloading roller is that by adding a tire unloading roller brake device, the vulcanizer tire unloading method is changed, the tire parking station is simply and effectively increased, and the tire unloading time can be controlled by the main conveyor belt, which meets the main conveyor belt's requirements for the vulcanizer tire unloading time, reduces the waste of personnel caused by tire squeezing on the main conveyor belt, saves time, and eliminates the safety hazards caused by manual intervention in tire unloading.

[0004] However, this patent locks the unpowered rotating rod when braking, thereby increasing the friction between the tire and the unpowered rotating rod, and then completing the braking. However, due to the large weight of the tire and the relatively smooth surface of the unpowered rod, the braking effect is unstable, and it is easy to slip or even fail to brake. In view of this, we propose a roller brake mechanism. Utility Model Content
