3 results about "Product diversity" patented technology

This invention discloses a product diversity complementary recommendation method in the field of e-commerce. The method includes: inputting the product category label of the target product into a pre-trained large language model to determine the complementary relationship between the target product and candidate products; constructing a product complementarity graph by treating products as nodes and the complementary relationship between the target product and candidate products as edge information; establishing neighbor relationships for the target product based on the product complementarity graph, combining the feature vectors and edge information of neighbor nodes; learning the product embedding representation through a graph neural network based on the neighbor relationships to determine the product embedding vector; determining the set of neighbor nodes for the target product based on the similarity between product embedding vectors; weighting intra-class complementarity and inter-class complementarity to select multiple product neighbors from the target product's set of neighbor nodes; and performing a self-balancing re-ranking of the comprehensive scores of the product neighbors through a constructed relevance-diversity weight mechanism to obtain the final recommendation result.

The present invention provides a conveying device, including a first conveying section and a second conveying section and a third conveying section arranged downstream of the first conveying section, and a fourth conveying section and a fifth conveying section are arranged downstream of the second conveying section. When the product is a separated product, the product can be optionally conveyed to the corresponding receiving device by the third conveying section or the fourth conveying section; when the product is a continuous product, the product is conveyed to the corresponding receiving device by the fifth conveying section or by the fourth conveying section and the fifth conveying section at the same time; the conveying device also includes a swing plate that can be located in a first position or a second position. When the swing plate is in the first position, the first conveying section is connected to the second conveying section, and when the swing plate is in the second position, the first conveying section is connected to the third conveying section. Through the above arrangement, continuous products and separated products can be flexibly conveyed and configured to meet the requirements of product diversity and the needs of diversion and multi-function. The present invention also provides a disposable absorbent product production system using the above conveying device.

The utility model relates to the technical field of machinery, and discloses a sponge composite cotton sticking device which comprises a base, a compression roller device is arranged on the rear side of the base, supporting columns are fixedly connected to the four corners of the base respectively, a conveying belt is arranged at the top of the base, and connecting square plates are arranged at the left end and the right end of the bottom of the conveying belt respectively. The top of each connecting square plate is fixedly connected with a blocking plate, the bottoms of the two connecting square plates are fixedly connected with connecting short columns, a second motor is installed in the middle of the base, the output end of the second motor is fixedly connected with a fixing cylinder, and a square plate is arranged at the top of the fixing cylinder. According to the sponge conveying device, the second motor is started, the square plate rotates, the rotating circular plates at the two ends of the square plate rotate and enable the connecting plate to rotate, and the fixed cylinders connected with the short connecting columns move towards the two sides, so that the conveying area is enlarged, the areas of sponge and materials are enlarged, the diversity of products is achieved, and the working efficiency is improved.
