Trademark retrieval device based on feature comparison of graph and character

Abstract

The invention discloses a trademark retrieval device based on feature comparison of a graph and a character. The trademark retrieval device comprises supporting legs, a working table is fixedly arranged above the supporting legs, a winding roller is arranged on the inner side of a first supporting rod so as to facilitate cooperation with a trademark pulling roll through the willing roller for winding a trademark roll, a unwinding roller is arranged on the inner side of a second supporting rod so as to facilitate unwinding usage of the trademark roll, positioning columns are inserted into cavities formed in the two ends of the winding roller and the unwinding roller, so that the positioning columns are made to be inserted into positioning grooves under cooperation of springs and chucks, thetrademark roll and the trademark pulling roll can be conveniently installed, the upper surfaces of positioning plates are provided with universal ball bearings, so that the trademark roll and the trademark pulling roll operate smoothly under the action of the universal ball bearings, the trademark roll can be more rapidly detected, limiting plates are fixedly arranged on the two sides of the upper surface of each positioning plate, the position of the trademark roll is not easy to deviate, and the detection efficiency of the trademark roll is improved.

Description

technical field [0001] The invention relates to the technical field of trademark retrieval, in particular to a trademark retrieval device based on comparison of graphic and text features. Background technique [0002] A trademark is a small piece of fabric used as a product mark. During production, it is continuously woven into a ribbon shape, and then the ribbon-shaped trademark belt is cut into a single trademark. Each small piece of fabric is marked with the brand name, manufacturer, graphics, specifications, etc., and the size depends on the needs. The trademarks are divided into two types: printing and jacquard. During the assembly line production process of trademarks, it is always necessary to use some trademark qualified product detection devices to check whether the produced trademark products meet the requirements. The quality of products can be guaranteed by screening qualified products for trademarks. Some small factories sometimes It is often judged by the prod...

Problems solved by technology

During the assembly line production process of trademarks, it is always necessary to use some trademark qualified product detection devices to check whether the produced trademark products meet the requirements. The quality of products can be guaranteed by screening qualified products for trademarks. Some small factories sometimes It is often judged by the production personnel themselves whether the trademark is qualified or not, which increases the work intensity of the workers and the production cost, and cannot guarantee high efficiency of trademark qualified inspection
