The invention discloses a double-station laser coding device and an operation method thereof. The device comprises a frame, a first coding platform mechanism, a second coding platform mechanism, a laser coding mechanism, a first code scanning platform mechanism, a second code scanning platform mechanism, a code scanning mechanism, a material moving mechanism, a product feeding mechanism and a product receiving frame. The invention adopts two groups of coding platform mechanisms, and is equipped with two groups of lasers and CCD galvanometer coaxial components to form double-station laser coding, which are independently controlled and do not affect each other, and are equivalent to integrating two single-station laser coding devices, thereby greatly improving the coding efficiency. Two groups of code scanning platform mechanisms are adopted to form double-station code scanning, and a common set of scanning mechanisms are used. The double stations alternately operate to scan codes, and the working time of the scanning mechanisms is fully utilized, thereby greatly improving the scanning efficiency. The invention has both coding and scanning functions, and integrates coding and scanning on one device, thereby reducing a scanning process, a set of scanning equipment and labor, thereby improving production efficiency and reducing costs.

A coffee grinder includes a main unit with a mounting hole on its top. A top cover is provided covering the mounting hole, and a bean hopper assembly is rotatably mounted on the top cover. A blade assembly is connected to the bottom of the top cover via a lifting assembly, and the bean hopper assembly and the blade assembly are conductively connected. A retaining ring is installed at the bottom of the bean hopper assembly, and the retaining ring is connected downward to the lifting assembly. Rotating the bean hopper assembly drives the lifting assembly to rotate, thereby adjusting the gap of the blade assembly. The retaining ring has an external snap fastener that engages with an external snap groove on the top cover. The advantages of this invention are: the rotation of the bean hopper assembly drives the rotation of the lifting assembly, making adjustment convenient, avoiding the interference problems of traditional adjustments, and improving the user experience.
