Description

Technical Field

[0001] The utility model relates to the technical field of control instruments, in particular to a belt scale weighing control instrument. Background Art

[0002] Belt scale products are mainly divided into two forms: single weighing area and multiple weighing areas. Based on this, the belt scale instruments in use are mainly divided into two types: one analog sensor input and multiple analog sensors. The instruments used in traditional belt scale measurement are divided into two sensor input modes. One is the full parallel working mode. All sensor excitation power lines of a belt scale are connected together, and the signal output lines of the sensors are also connected together and input to the instrument. The other is the analog switch branch input mode, which amplifies and processes the sensor signals separately, and uses analog switches to switch each channel for single digital-to-analog conversion and unified processing. The sensor excitation power supply adopts the parallel power supply mode;

[0003] Among them, the high-precision belt scale weighing meter is the main component of the belt scale weighing product. It is a branch input, high-speed, high-precision belt dynamic metering control instrument, mainly used in high-precision multi-weighing structure belt scale products, complete the high-speed conversion of analog sensor signals to digital signals, speed sensor height reading, processing, and through the calculation logic to complete the cumulative calculation of weight and display and store it in the belt scale meter, and can also upload the data to the host computer through the bus to display the weight data. At present, during the use of the belt scale weighing control instrument, it is easy to fog due to high humidity or large temperature difference in the working environment. When there is a lot of accumulation of fog, it will affect the numerical display of the display screen on the weighing meter, thereby affecting the normal operation of the belt scale weighing control instrument. In the prior art, the above problem is usually solved by disassembling the outer shell of the belt scale weighing control instrument and then wiping the water mist inside the display screen. However, repeated disassembly and installation are likely to cause the loosening and falling of the internal components of the belt scale weighing control instrument, which will still affect the normal operation of the belt scale weighing control instrument.

[0019] Furthermore, a protective cover is detachably connected to the protective tube, and two connecting blocks are symmetrically connected to the protective cover. Connecting screws are threadedly arranged between the two connecting blocks and the protective tube.

[0020] As a further solution of the present application, a mounting groove for mounting the display screen is provided on the front panel, and the depth of the mounting groove is greater than the thickness of the display screen.

[0021] On the basis of the above-mentioned solution, two sliding plates are symmetrically connected to the sliding block, and the supporting tube is provided with sliding grooves for the sliding plates to slide.
