Embodiment Construction
[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the invention.
[0017] like figure 1 As shown, the two ends of the symmetrical balance frame 2 are respectively suspended with a load tray 8 and a standard mass tray 7. The symmetrical balance frame 2 maintains a balance when both the load tray 8 and the standard mass tray 7 are unloaded, and the light weight displacement is enlarged. The rod 3 is horizontally fixed on the symmetrical balance frame 2, the light-weig...

The invention discloses a balance type accurate weighing device. The two ends of the symmetrical balance frame hang the load tray and the standard quality tray respectively. The enlarged thin rod is fixed horizontally on the symmetrical balance frame. One end of the light spring is fixedly connected to one end of the enlarged thin rod. Fixed directly on the side of the light spring, the light spring is connected to the sliding rheostat through a hard pointer, the middle of the hard pointer is connected to the input end of the voltage difference collector through a wire, and the midpoint of the sliding rheostat is connected to the voltage difference collector through a lead wire. The input terminal of the voltage difference collector is used to collect the voltage difference between the two input terminals, the output terminal is connected to the input terminal of the motor, the output terminal of the motor motor is connected to the variable speed conveyor belt, and the variable speed conveyor belt is set horizontally beside the load pallet. The output side of the variable speed conveyor is directly in the center of the load pallet. The invention has ingenious structure, high weighing and subpackaging efficiency, and accurate weighing.
Description
technical field [0001] The invention relates to the field of automatic standard weighing and packaging, in particular to a balance-type accurate weighing device. Background technique [0002] Today, automated production lines play a very important role in the industrial field. For the problem of weighing and sub-packaging of the specified quality of small products, manual operation and weighing and sub-packaging still occupy an important position. Manual operation is performed through electronic balance weighing. Although it is more accurate, it is time-consuming and labor-intensive, and the cost is high, which is also a large expenditure for the factory. The automatic weighing and sub-packaging can not only ensure the same quality accuracy as manual labor, but also improve the efficiency of sub-packaging, reduce safety hazards and reduce costs. When using a balance for weighing, it may encounter large disturbances, which may interfere with the accuracy and time of the weig...
