The invention discloses a structure provided with multiple rings of annular shaver net bodies and capable of forwards rotating and reversely rotating. The structure comprises a shaver net which is commonly constituted by the first shaver net body 1, the second shaver net body 2, the third shaver net body 3 and the multiple rings of shaver net bodies, the second shaver net body 2 is arranged in thefirst shaver net body 1, and the third shaver net body 3 is arranged in the second shaver net body 2; the first shaver net body 1, the second shaver net body 2, the third shaver net body 3 and the multiple rings of shaver net bodies forwards rotate or reversely rotate with a mounting shaft 5 as a symmetry point, and inner blades are arranged in the first shaver net body 1, the second shaver net body 2, the third shaver net body 3 and the multiple rings of shaver net bodies correspondingly; and a plurality of beard inlet grooves 4 are formed in the upper surfaces of the first shaver net body 1, the second shaver net body 2, the third shaver net body 3 and the multiple rings of shaver net bodies correspondingly. The arranged multiple rings of annular shaver net bodies and beard inlet grooves can forwards rotate and can also reversely rotate, thus the shaver net can actively capture beard, the shaving efficiency is higher, the structure is simple, and good using prospects are achieved.

The invention discloses a photographing device for industrial visual inspection, which comprises a bottom plate, two fixed sleeves are arranged on the upper surface of the bottom plate through a moving frame, and inside the two fixed sleeves are provided with a device for changing the placement position of workpieces. Two sets of support and deflection mechanisms; each set of support and deflection mechanisms includes a rotating sleeve and a fixed plate, the rotating sleeve is rotatably mounted on the inner wall of the fixed sleeve, the fixed plate is fixedly mounted on the upper surface of the bottom plate, and the upper part of the fixed plate A second gear is rotatably installed, and the support plate is arranged inside two rotatable sleeves, one of which is equipped with a camera for taking pictures of the workpiece in different directions. Through the setting of the support deflection mechanism, the invention can realize taking pictures of different positions of the workpiece, so that the image of the object can be captured more comprehensively and the detection quality can be improved.

The invention belongs to the field of user modeling and recommendation systems, and specifically relates to a meta-path-based context-aware user modeling method and a sequence recommendation method, aiming to solve the problem that the existing user modeling methods only consider the simple sequence relationship of user historical behavior, Complex user preferences cannot be captured; the accuracy of the existing recommendation system recommendations is not high, and the recommended content does not have diversity. The present invention acquires local interest representations based on the sequence of items accessed by users, obtains context-aware global interest representations by modeling heterogeneous networks, and combines local interest representations and global interest representations to obtain user comprehensive interest representations. Based on the user's comprehensive interest representation and the items to be predicted, the recommendation results are obtained through the recommendation model. The user modeling method of the present invention can more comprehensively capture user interests, and is beneficial to improving the accuracy of the recommendation system; the meta-path-based context-aware sequence recommendation method has high recommendation accuracy and more diverse recommendation contents.
