Title:
AUTOMATIC SCREENING APPARATUS FOR ORNAMENTAL GEMS PRIOR TO VACUUM COATING
Document Type and Number:
WIPO Patent Application WO/2022/105186
Kind Code:
A1
Abstract:
An automatic screening apparatus for ornamental gems prior to vacuum coating, comprising: a machine frame (1), a screening roller (2), and a recycling hopper (3). One working platform (11) and two operating mesas (12) are provided on the top part of the machine frame (1). The recycling hopper (3) is mounted and fixed within the machine frame (1). A set of first moving mechanisms (4a) and second moving mechanisms (4b) are mounted on the machine frame (1). The first moving mechanisms (4a) are arranged on two sides of the working platform (11). At least one screening roller (2) and a power motor (5) driving the screening roller (2) to rotate are mounted above the first moving mechanisms. Two sets of second moving mechanisms (4b) respectively span the two operating mesas (12) and are higher as a whole than the first moving mechanisms (4a). Several clamping components (6) are mounted and fixed on the second moving mechanisms (4b). The automatic screening apparatus replaces manual screening, is fast, prevents screening misses, increases production efficiency, and at the same time, by avoiding the phenomenon of reworking due to screening misses, reduces production costs.
