Description

Technical Field

[0001] The present invention relates to the technical field of scanning platforms, and in particular to a warehouse entry and exit scanning platform. Background Art

[0002] The in-and-out scanning platform is just like the scanners at the cash registers in major supermarkets. It is a device that scans and records the stripe codes on items. Most of the existing in-and-out scanning platforms on the market are integrated with RFID radio frequency identifiers, power amplifiers, industrial control touch-screen all-in-one computers and other equipment. Electronic tags are bundled with personnel work permits and each tool, and a unique ID is assigned. The operator needs to place the tools on the scanning platform for automatic scanning to record their in-and-out status, and collect detailed in-and-out data information, and automatically enter it into the ledger. It adopts the B / S design mode and platform system design concept to accurately identify tools and personnel in and out of the warehouse, intelligently enter the ledger, and form an intelligent management mechanism, providing a set of digital, networked, and automated safety monitoring comprehensive management platform for power safety production; it strengthens the safety management of live working tools, standardizes power production safety measures, improves power production safety guarantees, and prevents and guards against the occurrence of safety accidents. It is an innovative model for monitoring and management of live working tools.

[0003] When the in-and-out scanning platform is used in the warehouse, it is usually used in conjunction with the in-and-out conveyor belts in the warehouse. In order to prevent larger items on the conveyor belt from sliding directly onto the platform and causing a greater impact force, springs and other shock absorbers are usually installed at the bottom of the in-and-out scanning platform to alleviate the impact force.

[0004] However, the existing in-and-out warehouse scanning platform is not convenient for fine-tuning the height according to the in-and-out material conveying platform in the warehouse, which may cause up and down deviation, resulting in a large impact force when the items fall on the platform, and it is not convenient to adjust the elastic force of the spring according to actual needs. For example, when the elastic force of the spring is too small and soft, it will cause the platform to jump up and down too much, affecting normal work. If the elastic force of the spring is directly too large and too hard, it will not have an effective buffering effect to reduce the vibration impact force and cannot meet the use requirements. In order to further improve this phenomenon, we have proposed an in-and-out warehouse scanning platform. Summary of the invention

[0029] In this embodiment, the first motor 13 is started in the positive direction, and the first motor 13 drives the two screws 11 to rotate. Under the action of the threaded holes provided on one side of the moving seat 14, the rotation of the two screws 11 can drive the two moving seats 14 to slide towards each other on the two T-shaped slide rails 3, and the moving seat 14 drives the corresponding rotating plate 15 to press the support plate 9 upward.

[0030] When an object falls on the scanning platform body 1, it will drive it to vibrate up and down.

Since the support plate 9 is supported by the two rotating plates 15 at this time, the support plate 9 will not move up and down. At this time, when the screw rod 16 moves downward, it drives the pressure regulating plate 8 to compress multiple springs 10 downward. The reaction force of the spring 10 buffers the screw rod 16 and the rectangular box seat 2 through the pressure regulating plate 8, thereby alleviating the vibration impact force. When the spring 10 is soft, it will cause the scanning platform body 1 to jump up and down too much. At this time Starting the second motor 17 in the positive direction drives the vertical rod 18 to rotate, and the vertical rod 18 drives the screw rod 16 to rotate through the square hole 20. Under the action of the screw hole 23, the rotation of the screw rod 16 can drive the pressure regulating plate 8 to slide downward on the four positioning shafts 7 and compress the spring 10, so that the spring 10 is in a slightly compressed or semi-compressed state before buffering, and the spring 10 in the compressed state has a greater damping force on the pressure regulating plate 8, thereby achieving a greater damping force on the rectangular box seat 2. At this time, the amplitude of the up and down vibration of the scanning platform body 1 becomes smaller when it is running again, and the elastic force of the spring 10 can be adjusted to achieve a balance between the vibration force and the jumping amplitude, thereby effectively alleviating the vibration impact force while reducing the jumping amplitude.
