DETAILED DESCRIPTION

[0028] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0029] like Figures 1-10 The RFID high-density file management device shown includes a cabinet 101, a control panel 102 is installed on one side of the middle front end of the cabinet 101, a retrieval area 103 is opened on the lower side of the middle front end of the cabinet 101, a limit frame 135 is installed on the front side wall of the cabinet 101, a closing belt 104 is slidably connected to the inner side of the limit frame 135, a retrieval port 105 is opened in the middle of the closing belt 104, and the closing belt 104 is arranged at the rear side of the retrieval area 103, and mounting frames 138 are provided on both sides of the limit frame 135.

[0030] Furthermore, in a specific implementation, people can store files through the cabinet 101. An RFID chip reader is installed inside the cabinet 101. The RFID chip on the file box can be read by the reader, so that the file entry and exit data can be read and recorded, and the file management can be realized. In actual use, people can deposit and withdraw files through the access port 105. In the process of depositing and withdrawing files, the stepping motors 137 on both sides can drive the winding roller to reel in or loosen the end of the closing belt 104, thereby driving the closing belt 104 to move, and realizing the movement of the position of the access port 105 on the closing belt 104. , so that people can access files at different positions on the storage rack 115 conveniently. In normal times, the side of the closing belt 104 can be rolled up by the stepping motor 137, so that the taking port 105 is moved to the side of the inner wall of the cabinet 101, so that the taking area 103 can be completely closed by the closing belt 104, which is conducive to the preservation of files. By setting the taking port 105 as a single slot, it can be flexibly moved while achieving the minimum opening state, so that when people access files, the amount of air entering the cabinet 101 can be greatly reduced, thereby greatly reducing the path and number of "bad objects" entering the cabinet 101, which is conducive to actual use.

[0031] Among them, a transmission belt group 2 139 is provided at the bottom of one side of the winding roller, and the winding roller is connected to the rotating shaft 2 143 through the transmission belt group 2 139.

The middle part of the outer periphery of the rotating sleeve 147 is fixedly connected to the bottom rod 146. The fixed rod 144 and the cross frame 148 are fixedly connected to the inner side of the cabinet 101.

[0032] Further, in actual implementation, when the archives need to be taken out, the transmission belt group two 139 at the bottom of the winding roller will drive the rotating shaft two 143 to rotate synchronously when the stepping motor 137 works. When the rotating shaft two 143 rotates, it will drive the driving bevel gear two 152 engaged with the coaxial driven bevel gear two 153 to rotate, further driving the threaded rod 154 fixed with the driving bevel gear two 152 to rotate. The rotation of the threaded rod 154 can drive the air tank 149 to move along the cross frame 148, so that the air tank 149 can move with the taking opening 105 on the closed belt 104, so that the air tank 149 can keep synchronization with the taking opening 105. When the storage rack 115 where the archives to be taken out is rotated to the taking area 103, the air pump 157 will start to work, and the air pump 157 will output gas through the pipe 151. The gas will enter the air tank 149 and be sprayed out through the gas outlet cylinder 150 at the bottom of the air tank 149, so as to drive the impeller 145 at the bottom of the gas outlet cylinder 150 to rotate. When the impeller 145 rotates, it will drive the rotating sleeve 147 to rotate, and the bottom rod 146 fixed in the middle of the rotating sleeve 147 will be deflected synchronously. When the bottom rod 146 is deflected, it will abut against the bottom of the support plate 112, so as to lift the end of the support plate 112 through the bottom rod 146, form a slope and slide the archives box on the upper part out by a section, so that the end of the archives box to be taken out can exceed the taking opening 105, thereby facilitating people to quickly take out the archives.

[0039] Working principle:

[0040] In actual use, people can store archives through the cabinet 101. An RFID chip reader is installed inside the cabinet 101. The reader can read the RFID chip on the archive box, so as to read and record the archive in-out data and manage the archives. In actual use, people can store and take out the archives through the taking-out port 105. The work of the servo motor 116 can drive the lower rotating shaft 125 to rotate through the transmission belt set one 126, so as to drive the chain wheel 117 installed on the outer periphery to rotate synchronously. The lower chain wheel 117 can drive the upper rotating shaft 125 and the chain wheel 117 to rotate synchronously through the meshing circulating chain 122. The two coaxial chain wheels 117 can realize the synchronization of the two circulating chains 122. When the circulating chain 122 rotates, the storage rack 115 can be driven to move through the connected circulating chain 122. In this process, the limiting groove on the guide frame 118 can cooperate with the guide column 136 on the guide rod two 120 to guide and limit the storage rack 115, so that the storage rack 115 can always keep vertical. The movement of the storage rack 115 can switch the positions of different storage racks 115, so that different storage racks 115 can cooperate with the taking-out area 103 to store and take archives, which is beneficial to actual use. In the process of storing and taking archives, the two step motors 137 can drive the winding rollers to wind or loosen the end of the closure belt 104, so as to drive the closure belt 104 to move, realize the movement of the position of the taking-out port 105 on the closure belt 104, and facilitate people to store and take archives at different positions on the storage rack 115. In daily life, the step motor 137 can wind the closure belt 104 on one side, so that the taking-out port 105 is moved to the inner wall of the cabinet 101, so that the taking-out area 103 can be completely closed through the closure belt 104, which is beneficial to the preservation of archives. After the cabinet 101 is closed, the two fans 111 are started. The work of the fan 111 can extract the gas in the middle of the cabinet 101 through the through hole 110. The extracted air can be discharged from the air cylinder 108 through the one-way valve 109, enter the space on both sides of the cabinet 101, and enter the bottom space of the bottom plate 114 through the bottom communication channel, and further discharge from the inside of the cabinet 101, so as to maintain a good low-dust dry environment in the cabinet 101, which is beneficial to the preservation of the archives inside the cabinet 101. When the air humidity in the cabinet 101 is high, the RFID chip label may be condensed, which may cause damage to the RFID chip in the label. This is beneficial to the long-term use of the RFID chip label, and can effectively avoid the deposition of dust in the air on the archives, which is convenient for long-term storage of archives. The taking-out port 105 is set as a single slot, which can be moved flexibly while realizing the smallest opening state,Therefore, when people access the archives, the amount of air entering the cabinet 101 can be greatly reduced, thereby greatly reducing the path and quantity of "unwanted objects" entering the cabinet 101, which is beneficial to actual use. When the stepping motor 137 is working, the transmission belt group two 139 at the bottom of the winding roller will drive the rotating shaft two 143 to rotate synchronously. When the rotating shaft two 143 rotates, it will drive the driving bevel gear two 152 engaged with it to rotate through the coaxial driven bevel gear two 153, and further drive the threaded rod 154 fixed with the driving bevel gear two 152 to rotate. Through the rotation of the threaded rod 154, the air tank 149 can move along the cross 148, so that the air tank 149 can move with the taking opening 105 on the closed belt 104, so that the air tank 149 can keep synchronization with the taking opening 105. When the storage rack 115 where the required archives are located is rotated to the taking area 103, the air pump 157 will start to work. The air pump 157 will output gas through the through pipe 151, and the gas will enter the air tank 149 and be sprayed out through the gas outlet cylinder 150 at the bottom of the air tank 149, so as to drive the impeller 145 at the bottom of the gas outlet cylinder 150 to rotate. When the impeller 145 rotates, it will drive the rotating sleeve 147 to rotate, and the bottom rod 146 fixed in the middle of the rotating sleeve 147 will be deflected synchronously. When the bottom rod 146 is deflected, it will abut against the bottom of the support plate 112, so as to lift the end of the support plate 112 through the bottom rod 146, form a slope, and slide the upper archive box out by a certain distance, so that the end of the archive box to be taken out can exceed the taking opening 105, thereby facilitating people to quickly take out the archives. When storing archives, the air pump 157 does not work, so that people can directly store archives. During the process of storing archives, when the upper rotating shaft 125 rotates, the driving bevel gear one 127 will drive the driven bevel gear one 128 engaged with it to rotate, and the driven bevel gear one 128 will drive the rotating shaft one 129 to rotate. The driving gear 132 fixed at the bottom of the rotating shaft one 129 will drive the driven gear 141 engaged with it to rotate synchronously, and the driven gear 141 will drive the rotating rod 142 fixed with it to rotate. When the rotating rod 142 rotates, the crankshaft 130 fixed on the outer periphery will rotate, and through the protrusions arranged on the outer periphery, the crankshaft 130 will abut against the sliding frame 123 on one side when rotating, thereby driving the sliding frame 123 on one side to translate when the crankshaft 130 rotates. The reset spring 131 can reset the sliding frame 123, so that the crankshaft 130 can continuously move when rotating, and the upper and lower cleaning rollers 140 can form a wave-shaped fluctuation, thereby contacting the archive box on the storage rack 115 on one side, pushing the archive box into the storage rack 115, keeping the archive box stable, and cleaning the front RFID tag of the archive box through the cleaning roller 140, avoiding dust and water vapor deposited on the RFID tag or condensed water vapor, which is beneficial to actual use.
