Visible, the hair cutting device in the utility model, can improve the user's experience.

The application discloses a closed dust-free semiconductor packaging conveying device, which comprises a rack, a driving mechanism, a sliding table, a tray and an air filtering device, a gear shaft is suspendedly arranged in the rack, the front and rear ends of the gear shaft penetrate through the rack and are rotationally connected with the rack, the rear side of the rack is provided with the driving mechanism, and the driving mechanism is connected with the gear shaft. The closed dust-free semiconductor packaging conveying device is provided with an air inlet, a first air outlet and a vacuum pump, the vacuum pump extracts air through the air inlet, clean air is formed after the air is filtered through the air filtering device, then the clean air is discharged into the sealed cover through the first air outlet, the regular airflow is formed on the two sides of the sealed cover through the above structure, dust invasion into the inside of the sealed cover is avoided due to the influence of vortex flow, turbulent flow and the like, meanwhile, the sealed cover wrapped outside the rack further improves the sealing effect, the material is convenient for long-distance transportation, and the requirement for the workshop is reduced.

This utility model relates to the technical field of adhesive production equipment and discloses an automatic adhesive batching and mixing device, including an inclined support and a shuttle-shaped material tank. A feed pipe is rotatably provided on one side of the inclined support, and a batching component is provided at the feed end of the feed pipe. The feed pipe is rotatably connected to one end of the shuttle-shaped material tank. A discharge pipe is rotatably provided on the other side of the inclined support. A stirring rod connecting the feed pipe and the discharge pipe is provided inside the shuttle-shaped material tank, and the discharge pipe is rotatably connected to the other end of the shuttle-shaped material tank. By rotatably connecting the feed pipe and the discharge pipe to the shuttle-shaped material tank, a rigid connection between the shuttle-shaped material tank and the feed pipe and discharge pipe is avoided. A drive component can drive gear ring one and gear ring two to rotate in opposite directions. Gear ring one and gear ring two can respectively drive the shuttle-shaped material tank and the stirring rod to rotate in opposite directions, forming a powerful shearing and kneading effect, completely eliminating mixing dead zones.

This application discloses a cushioning-optimized athletic shoe sole. The midsole includes an upper midsole, a middle midsole, and a lower midsole, all with increasing hardness. The forefoot support includes a rigid upper forefoot piece, a rigid middle forefoot piece, and a soft lower forefoot piece stacked from top to bottom. The middle and lower forefoot pieces fill the first and second forefoot openings, respectively. In this cushioning-optimized athletic shoe sole, when the forefoot support is compressed, the upper forefoot piece provides relatively firm cushioning based on the middle midsole, the middle forefoot piece provides even firmer cushioning based on the lower midsole, and the lower forefoot piece is soft, avoiding a rigid connection with the outsole. When subjected to greater pressure, the lower forefoot piece is compressed, resulting in the firmest cushioning effect, ultimately providing a multi-layered cushioning effect. The rear support also provides different cushioning effects in layers.

The utility model discloses a kind of under-inclination chute's anti-blocking dredging device in gangue material transfer technical field, including feed hopper and fixedly installed under discharge chute section of feed hopper, and the bottom plate inner surface of discharge chute section is provided with the protruding flow disturbing structure;The bottom plate outside of discharge chute section is installed with vibration motor by high rigidity flange, and vibration transmission plate is provided between the two;The side plate trepanning of feed hopper is connected with air compressor in trepanning, and the end of pipeline of air compressor that extends into feed hopper interior is connected with at least one nozzle, and nozzle points to the inlet accumulation area of discharge chute section;Discharge chute section below is fixedly connected with chute support with damping device, and damping device is arranged in multiple-point symmetry below chute support.The utility model effectively solves the problem that under-inclination chute is easy to block, space requirement is high, improves conveying efficiency and reduces reconstruction engineering difficulty.
