Description

Technical Field

[0001] This utility model relates to the field of electromagnetic lock technology, and in particular to a circulating electromagnetic lock. Background Technology

[0002] The circulating electromagnetic lock is mainly used in the conveyor belt or vending machine conveyor belt. Items are arranged in sequence on the top of the fixed rack, and the electromagnetic lock is used to release items in sequence as needed. When the electromagnetic lock is open, goods can pass through and be released. When it is closed, the passage of goods is restricted and the release is stopped.

[0003] Chinese patent application number "CN202323293895.6" is entitled "A Cyclic Electromagnetic Lock," which includes: an electromagnetic lock body; a fixing frame snapped onto the upper end of the electromagnetic lock body; a rotating mechanism fixedly mounted on one side inside the electromagnetic lock body; the rotating mechanism including a fixing box; an isolation plate fixedly mounted on the other side inside the electromagnetic lock body; a fixing rod slidably mounted inside the isolation plate; a second magnet fixedly mounted on one side of the fixing rod; and an annular plate rotatably mounted inside the other side of the electromagnetic lock body. This device limits the movement of items using the annular plate, but the following problems still exist in actual use: 1. The bracket is set at an angle and has anti-slip texture on the upper side, so it is difficult for light objects to slip off; 2. The electromagnetic lock body containing the ring plate has an opening. If the size of the object is smaller than the opening, the object will fall into the opening when it falls, resulting in delivery failure. Utility Model Content

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Reference Figure 1-4 This utility model embodiment provides a circulating electromagnetic lock, which includes an electromagnetic lock body 1. An inclined block 2 is fixedly connected to the right end of the electromagnetic lock body 1, and a support column 5 is fixedly connected to the upper four sides. The inclined block 2 is generally cylindrical. Both the electromagnetic lock body 1 and the inclined block 2 are made of metal. The height of the support column 5 is determined according to the height of the conveyed item. A partition 14 is fixedly connected between the two support columns 5. Under the action of the partition 14, the item is prevented from falling from both sides when moving. A sliding groove 11 is provided on the electromagnetic lock body 1 located in the middle of the support column 5. Limiting grooves 12 are provided on both sides of the sliding groove 11. A sliding plate is slidably connected in the sliding groove 11. The surface of the sliding plate is smooth, which facilitates the movement of the item. The upper end of the support column 5 is fixedly connected to the mounting plate 4. There are two mounting plates 4, which are symmetrically arranged. A rotating shaft 6 is rotatably connected between the two mounting plates 4. A servo motor is fixedly connected to one side of the mounting plate 4. The servo motor is connected to the vending machine control board. Its working principle and connection method are existing technologies and are conventional technologies in this field, so they will not be described in this patent. The output end of the servo motor is fixedly connected to the rotating shaft 6. A gear 7 is fixedly connected to the rotating shaft 6. A synchronous belt 8 is meshed between the two gears 7. The synchronous belt 8 is made of rubber and has teeth on the inner side that are adapted to the gear 7. A push plate 9 is fixedly connected to the outer side of the synchronous belt 8. The length and spacing of the push plate 9 are determined according to the size of the item. When the vending machine is working, the servo motor drives the gear 7 to rotate. The gear 7 drives the synchronous belt 8 and the push plate 9 to rotate, so that the push plate 9 pushes the outermost single item onto the tilting block 2. A stepper motor 10 is fixedly connected to one end of the electromagnetic lock body 1 near the tilting block 2. The output end of the stepper motor 10 is slidably connected to the tilting block 2 and is located on the right side of the tilting block 2. A baffle 3, made of transparent plastic, is fixedly connected to the output end of the stepper motor 10. A guide block 31 is fixedly connected to the inner side of the baffle 3. An annular groove 13 is provided on the side of the tilting block 2 near the baffle 3. The guide block 31 is located in the annular groove 13 and is slidably connected to the annular groove 13. Under the action of the baffle 3, the item is first blocked to prevent it from falling directly. After the customer confirms the selection... When the stepper motor 10 is started, the baffle 3 rotates one revolution under the action of the stepper motor 10, so that the item falls into the dispensing port. At this time, the vending machine stops after dispensing the item. If the customer cancels the selection, the stepper motor 10 still rotates the baffle 3 one revolution. At this time, the item falls into the vending machine, and the customer can make a selection again. The internal structure of the dispensing port is a double channel, and the dispensing plate swings left and right by the motor. If the customer confirms, the dispensing plate is connected to one side of the dispensing port. If the customer cancels, the dispensing plate is connected to one side of the internal storage space of the vending machine.

[0017] Working principle: When in use, after the customer selects an item, the servo motor is started. The servo motor drives the gear 7 to rotate, and the gear 7 drives the synchronous belt 8 and the push plate 9 to rotate. This causes the push plate 9 to push the outermost single item onto the tilting block 2. At this time, under the action of the baffle 3, the item is blocked to prevent it from falling directly. After the customer confirms the selection, the stepper motor 10 is started. Under the action of the stepper motor 10, the baffle 3 rotates one revolution, causing the item to fall. At this time, the vending machine stops after dispensing the item.

[0018] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
