Title:
香料破砕グラインダー及びその自動開閉制御装置
Document Type and Number:
Japanese Patent JP5097005
Kind Code:
B2
Abstract:
A grinder includes a hollow base (2), a receptacle (4) and an automatic open/close control device (6) respectively coupled to top and bottom sides of the hollow base, a grinding unit (3) mounting in between the receptacle (4) and the automatic open/close control device (6), and a housing (5) that houses the hollow base (2) and the lower part of the receptacle (4). The automatic open/close control device (6) comprises a follower member (61), which is connected to the hollow base (2) to hold a transmission shaft (1) and has radial blocks (613) and guide slots (614) radially and alternatively disposed at the bottom side, a bottom cover (62), which has outlets (624) corresponding to the guide slots (614) of the follower member (61), and a position-limitation structure provided between the follower member (61) and the bottom cover (62) to secure the bottom cover (62) to the follower member (61) and to limit relative rotary motion between the follower member (61) and the bottom cover (62) within a predetermined angle, and a torsion spring (63) connected between the follower member (61) and the bottom cover (62) in such a manner that when the friction force produced during grinding of the grinder is greater than the torsional force of the torsion spring (63), the follower member (61) is rotated relative to the bottom cover (62) from a first position where the radial blocks (613) of the follower member (61) block the outlets (624) of the bottom cover (62) to a second position where the radial blocks (613) of the follower member (61) are moved away from the outlets (624) of the bottom cover (62) and the guide slots (614) of the follower member (61) are moved into alignment with the outlets (624) respectively for discharge of ground powder out of the grinder through the guide slots (614) and the outlets (624), and at the same time the torsion spring (63) is twisted to preserve energy.
