Description

Technical Field

[0001] The utility model relates to the technical field of demagnetization devices, in particular to an automatic demagnetization device for a supermarket cashier counter. Background Art

[0002] As an indispensable supporting facility in shopping malls and supermarkets, the cash register is increasingly concerned by customers. The cash register, commonly known as the payment counter, is where customers pay for transactions and where they last stay in the store. The supermarket automatic demagnetization device is part of the supermarket anti-theft system. It is generally installed at the exit of the supermarket. It will automatically demagnetize when magnetic objects are detected. This device can protect the supermarket's goods from being stolen and improve the supermarket's anti-theft capabilities.

[0003] At present, many supermarkets have set up many self-service checkout counters in order to save labor costs and other reasons. Such self-service checkout counters often adopt an integrated design of code scanning and demagnetization for demagnetizing product labels, which makes it more convenient for customers to demagnetize compared with the demagnetization plate of the manual checkout counter. However, when the integrated design of code scanning and demagnetization is in use, it is easy for the code scanning window to interact with the electromagnetic interference of the external machine to affect the normal demagnetization, resulting in the problem of demagnetization failure. Based on this, the utility model designs an automatic demagnetization device for supermarket checkout counters to solve the above problem. Utility Model Content

[0004] The utility model aims to provide an automatic demagnetization device for a supermarket cash register, so as to solve the problem in the above background technology that the scanning window and the electromagnetic interference of the external machine interact and affect the normal demagnetization, resulting in the failure of demagnetization.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic demagnetization device for a supermarket checkout counter, comprising a demagnetization device body, wherein demagnetization code scanning windows are provided on the inner side and the top of the demagnetization device body, and an outlet and an inlet are provided at both ends of the demagnetization device body, and two round rollers are fixed inside the end of the demagnetization device body close to the inlet, and a conveyor belt is sleeved on the two round rollers, and a motor is fixed on the side of the outside of the demagnetization device body away from the conveyor belt, and the round roller close to the outlet is fixedly connected to the output end of the motor, and fixing rods are fixed at both ends above the demagnetization device body, and detachable front anti-magnetic cloth and rear anti-magnetic cloth are fixed on the two fixing rods by bolts.

[0006] Preferably, the width of the demagnetization code scanning window at the top inside the demagnetization device body is equal to the width of the conveyor belt, and the conveyor belt is located directly below the demagnetization code scanning window at the top inside the demagnetization device body.

[0007] Preferably, the height of the demagnetization code scanning window on the side inside the demagnetization device body is equal to the height inside the demagnetization device body, and the width of the demagnetization code scanning window on the side inside the demagnetization device body is equal to the distance between the shipping port and the shipping port.

[0008] Preferably, the length between the two circular rollers is greater than the length between the outlet and the inlet, and the distance between the circular roller near one end of the outlet and the outlet is smaller than the distance between the circular roller near one end of the inlet and the inlet.

[0009] Preferably, a cleaning scraper is fixed on one end of the bottom of the demagnetization device body close to the cargo inlet, the cleaning scraper fits the outer surface below the conveyor belt, a detachable cleaning box is arranged below the cleaning scraper, and the cleaning box is fixed to the demagnetization device body by a buckle.

[0010] Preferably, the bottom end of the rear anti-magnetic cloth is in contact with the upper outer surface of the conveyor belt, and the length of the front anti-magnetic cloth is half of the length of the rear anti-magnetic cloth.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The utility model adopts a semi-enclosed structure. When a product enters the main body of the demagnetization device for scanning and demagnetization, the rear anti-magnetic cloth and the front anti-magnetic cloth at both ends of the main body of the demagnetization device will block the external electromagnetic interference. At the same time, the two demagnetization scanning windows inside the main body of the demagnetization device will demagnetize the product barcode at the same time, thus solving the problem of the interaction between the scanning window and the external machine electromagnetic interference affecting the normal demagnetization and causing the demagnetization failure.

[0013] (2) By cleaning the conveyor belt structure, the barcode of the product is straightened and leveled, and the barcode is placed opposite to one of the two demagnetizing scanning windows. The product can be demagnetized by scanning and demagnetizing the barcode. After the demagnetization is completed, the product is sent out through the delivery port for bagging. At the same time, when the conveyor belt rotates, the cleaning scraper under the conveyor belt cleans the conveyor belt, avoiding the situation where customers need to frequently pick up the product and align it with the scanning window when scanning the barcode by themselves. The clean conveyor belt also improves the customer's consumption experience. BRIEF DESCRIPTION OF THE DRAWINGS
