Temperature difference detection line for glass cup

The invention discloses a glass cup temperature difference detection line which comprises two circulating conveying belts, the two circulating conveying belts are parallel to each other and synchronously rotate in the same direction, a plurality of bearing devices used for driving cups to move are connected between the two circulating conveying belts, and the circulating conveying belts drive the cups to move from left to right. The cups sequentially pass through the low-temperature channel and the high-temperature channel and are parallel to the circulating conveying belt. According to the glass cup temperature difference detection line, the circular conveying belt is adopted to drive the bearing device to move and drive cups to move, the cups sequentially pass through the low-temperature channel and the high-temperature channel, under the change of high-low temperature difference, the high-temperature-change-resistant performance of the cups is detected, the phenomenon that cold cups meet hot water is truly
