Currently, the applicant is delivering warehouses with non-ferrous metals (such as copper, aluminum, zinc, nickel, etc.) designated for customers. Since nonferrous metals are manufactured in recent years, the quantity of warehouse entry and warehouse exit is increased year by year, and the quantity of warehouse entry and warehouse exit in the last year is over 200 ten thousand tons. According to the operation regulation, each non-ferrous metal goods in the warehouse must be weighed on site, and then warehouse entry processing is carried out according to the actual weight when the goods are weighed. Moreover, the metering tolerance specified by the country before 2017 is less than two thousandths, and the metering tolerance must be less than one thousandth from 2017, which provides more severe standards and requirements for the existing metering work of the applicant.
During actual metering operation, the mobile electronic scale used for field weighing is an electronic ground scale, and the electronic scale is provided with a 6V built-in battery jar which supplies power to circuits and other electronic components in the equipment. Because the operation place when passing the pound is not fixed, the pound scale needs to be moved at any time, and the 220V alternating current power supply can not be dragged due to safety consideration, so the equipment can only continuously work for about 2-3 hours by only depending on a built-in storage battery, and then the equipment is usually shut down due to insufficient electric quantity of the storage battery. In order to solve the problem, before the power supply device of the equipment is not improved, an operator takes the equipment to an office to charge or replace other standby equipment, and then the operator debugs the equipment again to continue weighing operation.
However, this drawback clearly severely affects the efficiency of the field weighing operation. According to the calculation of 8 hours of operation per shift, replacing standby equipment for more than 2 times wastes at least 2 hours, and a plurality of expensive standby equipment need to be purchased for replacement, so that a metering error with higher probability is caused, and the economic cost is not reduced. Meanwhile, due to the charging problem of the display of the electronic scale, the normal operation of field weighing operation is influenced, and a lot of inconvenience is caused to customers.

Referring to fig. 1 and 2, in the prior art, a mobile electronic scale display 1 includes at least an integrated circuit 10 and a built-in battery 12, and the integrated circuit 10 is powered by the built-in battery 12. For example, the internal battery 12 may be a battery P1 as shown in fig. 2. However, as described in the background art, during actual metering operation, the mobile electronic scale used for field weighing is electronically ground scale, and since the operation place is not fixed during weighing, the scale needs to be moved at any time, and the 220 v ac power supply cannot be pulled for safety, the device can only continuously work for about 2-3 hours by the built-in battery, and then the device is usually stopped due to insufficient battery capacity.
In order to solve the problem, the utility model provides an improved power supply device.
