This application relates to a stamping die and a stamping method. A first and second unloading member are spaced apart along the y-axis and form a processing groove for placing a sheet to be processed. A second preforming component, a second shaping component, and a second unloading member are movable with a limiting component along the x-axis. The first or second preforming component is movably inserted into the processing groove along the y-axis. The first shaping component is pressed against at least a portion of the preforming section along the y-axis, and the at least a portion of the preforming section is sandwiched between the first shaping component and the second unloading member. Alternatively, the second shaping component is pressed against at least a portion of the preforming section along the y-axis, and the at least a portion of the preforming section is sandwiched between the second shaping component and the first unloading member. The stamping die and stamping method provided by this application solve the problem that during the processing of a heat sink, the stamped portion is prone to twisting, deformation, or even rolling.

The utility model discloses drying equipment for textile thread dyeing, which relates to the field of textile drying and comprises a shell, a controller is arranged on the front side of the shell, a conveying device is arranged on the lower side of the shell, an air pump is arranged on the rear side of the shell, and a transmission device is fixedly connected to the rear end of the shell. The transmission device is fixedly connected with the first driving wheel, and the bottom of the transmission device is fixedly connected with the bottom of the inner wall of the shell. The electric heating drying lamp is arranged to control the temperature in the shell, the conveying device can intermittently convey spinning threads, the ironing device is arranged, the spinning threads are ironed in the drying process, the spinning threads fed into the shell can be pre-dried at high temperature and then conveyed to the position below the ironing device to be ironed, and therefore the spinning threads can be dried at high temperature. And then the textile threads are conveyed to the position below the electric heating drying lamp for final drying, so that each section of the textile threads can be uniformly ironed and dried, and it is guaranteed that the textile threads cannot be heated unevenly or distorted and deformed.

The present invention relates to a three-dimensional face reconstruction method, device, electronic device and storage medium. The three-dimensional face reconstruction method described in the present invention comprises: obtaining a face image to be reconstructed; preprocessing the face image to obtain a face image of standard size; inputting the face image of standard size into a trained face parameter recognition model to obtain face parameters corresponding to the face image; wherein the face parameters include posture parameters, shape parameters and expression parameters; according to the face parameters, calculating the three-dimensional vertex coordinates corresponding to the face image; saving the three-dimensional vertex coordinates to obtain a complete file containing a three-dimensional face model. The three-dimensional face reconstruction method described in the present invention can realize three-dimensional face reconstruction based on a single face image, without the need to collect high-precision three-dimensional face data.

The utility model relates to the technical field of greenhouse roof cleaning equipment, and provides a track device applied to a multi-span greenhouse roof cleaning machine and roof cleaning equipment, the track device mainly comprises a first track, a second track and a transition track; the first track and the second track are arranged at intervals in the length direction of the multi-span greenhouse; the first end of the transition rail is fixedly connected with the first rail, and the second end of the transition rail is slidably connected with the second rail. According to the track device applied to the multi-span greenhouse roof cleaning machine, the first track and the second track can achieve continuous arrangement of track faces through the transition track, wheels of the transfer platform cannot be suspended when passing through the gap between the first track and the second track, and operation safety of the roof cleaning machine and the transfer platform is guaranteed; and meanwhile, the first track and the second track cannot be distorted and deformed due to stress, so that the safety and reliability of the track device in different environments are ensured.
