[0005] To achieve the above purpose, the following technical solutions are used: a magnetic lock structure, comprising a feeding cylinder and a magnetic lock assembly, the top of the feeding cylinder is connected with a movable cover plate through a hinge, and the upper surface of the movable cover plate is fixed with a handle on the front side, the magnetic lock assembly comprises an adsorption magnetic sheet fixed on one side of the movable cover plate, the side surface of the feeding cylinder is fixed with an electromagnetic sheet box, and the two ends of the electromagnetic sheet box are rotatably connected with a transmission shaft and a drive shaft from front to back, the outer wall of the transmission shaft and the drive shaft is sleeved with a transmission belt, and the outer end of the drive shaft is connected with a one-way ratchet box, the outer side of the one-way ratchet box is connected with a transmission gear through a shaft body, the rear of the adsorption magnetic sheet is parallelly provided with an extension rod, and the end of the extension rod is connected with an arc gear rack through a support.
[0006] Further, the electromagnetic sheet box is located directly below the adsorption magnetic sheet, and the transmission belt passes between the electromagnetic sheet box and the adsorption magnetic sheet.
[0007] Further, the arc gear rack and the transmission gear are located in the same plane, and the center of the arc gear rack and the rotation center of the hinge are located on the same axis.
[0008] Further, when the movable cover plate rotates upward and opens around the hinge rotation center as the axis, the arc gear rack rotates concentrically clockwise, and the arc gear rack meshes with the transmission gear during the concentric clockwise rotation.
[0009] Further, when the arc gear rack meshes and drives the transmission gear to rotate clockwise, the transmission belt does not drive the drive shaft to rotate through the one-way ratchet box.
[0010] Further, the arc-shaped rack rotates concentrically counterclockwise when the movable cover plate rotates downward around the rotation center of the hinge, and the arc-shaped rack rotates concentrically counterclockwise to engage and drive the transmission gear to rotate counterclockwise, and the transmission gear rotates counterclockwise through the one-way ratchet box to drive the drive shaft to rotate.

[0012] Further, the recovery hopper is fixed below the electromagnetic sheet box, and the top opening size of the recovery hopper is greater than the outer opening structure size of the movable cover plate.
[0013] A magnetic lock system applied with the magnetic lock structure, the magnetic lock system comprises the following steps: S1, task allocation: The system background allocates the required work tasks to each hopper, and the feeding personnel scans the two-dimensional code of the hopper or inputs the hopper number by hand terminal to display the corresponding task allocation plan of the hopper on the terminal, and the task allocation plan includes task allocation number, processing model, and material name; S2, material matching verification: After selecting the target task allocation plan, the hand-held terminal scans the material label two-dimensional code to be fed, and the system automatically matches whether the material to be fed matches the task allocation plan, wherein each material generates a corresponding label two-dimensional code based on the task allocation plan, and then is sent to each hopper for waiting for feeding; S3, unlocking and feeding: When the material label two-dimensional code to be fed matches the target task allocation plan successfully, an unlocking instruction is sent to the magnetic lock assembly, the electromagnetic sheet in the electromagnetic sheet box is powered off and loses the magnetic attraction of the magnetic sheet, at this time, it indicates that the magnetic lock is opened, and then the movable cover plate is lifted by manually holding the handle to open the feeding opening of the hopper, and then manual feeding is performed; If the matching fails, the magnetic lock will not be opened, at this time, the movable cover plate cannot be lifted, and the hand-held terminal displays a matching failure.

When the matching material is manually added to the inside of the barrel, the manual operation is prone to cause the material, especially the granular material, to leak to the side, at this time, the part of the material leaking to the side falls to the surface of the conveying belt, and the movable cover is closed under rotation after the filling is completed, in this process, the arc-shaped rack rotates counterclockwise to engage and drive the transmission gear to rotate counterclockwise, and the driving shaft is driven to rotate through the one-way ratchet box, at this time, the transmission shaft cooperates with the rotation of the driving shaft to transmit the conveying belt, so that the part of the conveying belt surface loaded with the material moves and turns over, after the movable cover is closed, the electromagnetic sheet in the electromagnetic sheet box and the adsorption magnetic sheet are adsorbed to each other through the flat conveying belt. After the part of the conveying belt surface loaded with the material moves and turns over, the part of the material falls into the recycling hopper and flows back to the inside of the barrel through the opening under the action of gravity.
[0015] The present application provides a magnetic lock structure and a magnetic lock system, which have the following beneficial effects: 1. The magnetic lock structure and the magnetic lock system, through the standardized process of task allocation, material matching and unlocking and feeding, the system background first allocates the work task to each barrel, and the feeding personnel can view the corresponding task allocation plan by scanning the barrel two-dimensional code or inputting the number with the help of the handheld terminal, and then scan the material label two-dimensional code to complete the automatic matching of the system. Only when the matching is successful, the unlocking instruction is issued to the magnetic lock assembly, which completely eliminates the feeding errors caused by manual subjective judgment and avoids production accidents and material scrapping. At the same time, the process simplifies the operation steps, clearly defines the work target of the feeding personnel, effectively improves the feeding efficiency and the smoothness of the connection between the previous and subsequent processes.
[0016] 2. The magnetic lock structure and the magnetic lock system, when feeding, the accidentally leaked material will fall to the surface of the conveying belt, and will not adhere to the upper surface of the electromagnetic sheet box. When the movable cover is closed, the arc-shaped rack rotates counterclockwise with the movable cover around the hinge, engages and drives the transmission gear, and drives the driving shaft through the one-way ratchet box, cooperates with the transmission shaft to make the conveying belt rotate and turn over, and sends the material into the recycling hopper on the side of the barrel, and then flows back to the barrel through the opening at the bottom of the recycling hopper, reduces the waste of material, and avoids the problem that the accidentally leaked material is located on the upper surface of the electromagnetic sheet box, causing the movable cover to be not tightly closed and the adsorption magnetic sheet to be not stably adsorbed to the electromagnetic sheet box, without increasing additional operation and burden.

S3, Unlocking and Loading: When the QR code of the material label to be loaded is successfully matched with the target work plan, the unlocking command is issued to the magnetic lock assembly (5). At this time, the electromagnetic sheet inside the electromagnetic sheet box (502) is de-energized and the magnetic adsorption sheet (501) loses its magnetic adsorption. This indicates that the magnetic lock is open. Then, the manual person holds the handle (4) and lifts the movable cover plate (3) to open the feed port of the material cylinder (1). Then, the manual person can load the material. If the matching fails, the magnetic lock will not open.
