TECHNICAL FIELD
[0001] The utility model belongs to foaming line equipment technical field, especially relates to annular refrigerator door body foaming line motor train unit circulation car. BACKGROUND
[0002] In the production process of refrigerator door body foaming, the low accuracy of fixed-point conveying has been an important factor restricting production efficiency and product quality. Traditional conveying systems, such as mechanical arms or conveyors, often have problems such as long-term inaccurate positioning and unstable placement of the mold during conveying, leading to uneven distribution of foam and poor sealing during foaming. These problems not only affect the quality of the product, but also may lead to a decrease in production efficiency and waste of resources.
[0003] The limitations of traditional conveying systems mainly manifest in the following aspects. First, the positioning accuracy of mechanical arms or conveyors is limited, which cannot meet the long-term accurate positioning requirements of the mold for refrigerator door body foaming. With long-term use, the positioning accuracy of mechanical arms or conveyors may gradually decrease, leading to the displacement of the mold during conveying, affecting the uniformity and consistency of foaming. Second, traditional conveying systems are easily disturbed by external factors during conveying, such as equipment vibration and unbalanced loading, which further reduces the stability of conveying, causing the mold to shake and tilt during conveying, affecting the foaming effect. In addition, the structure of traditional systems is relatively simple, lacking effective stability and guidance mechanisms, which may cause the mold to shift or tilt during conveying, seriously affecting the foaming effect.
[0004] The existence of these problems makes it difficult for traditional conveying systems to meet the requirements of modern manufacturing for high precision and high efficiency in the production of refrigerator door body foaming. Therefore, there is an urgent need for a new conveying system that can provide high-precision fixed-point conveying to overcome the limitations of traditional conveying systems and improve production efficiency and product quality.
