High-value crystal tracing device based on block chain

Abstract

The invention provides a high-value crystal tracing device based on a block chain. The high-value crystal tracing device comprises a device main body, a paper flattening mechanism and a reset mechanism, wherein the device main body includes a frame body, an electrical appliance box, a display screen, a scanning head and a crystal information sheet; the frame body is arranged on a lower end face ofthe electrical appliance box; the display screen is arranged on a front end face of the electrical appliance box; the scanning head is assembled on a lower end face of the electrical appliance box; the crystal information sheet is assembled in the frame body; the paper flattening mechanism comprises a permanent magnet, a groove, a square rod I, a limiting groove, an electromagnet I, a blind holeI, an electromagnet II, a blind hole II, a sliding chute, a square rod II, a permanent magnet II, a through groove and a circular rod; and the reset mechanism includes a circular ring I, a rectangularcavity, a plugging plate, a blind hole III, a circular ring II, a pulley and an elastic rope. Compared with the prior art, the high-value crystal tracing device has the beneficial effects that the purpose of flattening paper is fulfilled, and the goal of automatic resetting is achieved.

Description

technical field [0001] The invention relates to a block chain-based high-value crystal traceability device, which belongs to the technical field of the Internet of Things. Background technique [0002] Blockchain technology, also known as "distributed ledger technology", is a technical solution for decentralization and collective maintenance of distributed ledgers. Its essence is realized by the collective participation of multiple nodes through multi-party storage and multi-party computing. Distributed database system with untamperable data and credible calculation results. [0003] In the prior art, there are still many deficiencies in the high-value crystal traceability device. When scanning and tracing the crystal information sheet, it cannot flatten the wrinkled paper due to the lack of paper flattening function, which is not conducive to the crystal information.

Problems solved by technology

[0003] In the prior art, there are still many deficiencies in the high-value crystal traceability device. When scanning and tracing the crystal information sheet, it cannot flatten the wrinkled paper due to the lack of paper flattening function, which is not conducive to the crystal information. Single scanning, and at the same time, when the round rod is used to flatten, due to the lack of reset function, manual recovery is required, and there are many operating steps. Therefore, a high-value crystal traceability device based on blockchain is urgently needed to solve the above-mentioned problems.
