Description
Technical Field
The invention relates to material weighing equipment, in particular to a drawer spiral composite type automatic material weighing machine.
Background
At present, material weighing equipment is mainly divided into the following parts:
1. the vacuum suction machine has the advantages that the equipment structure and the electric appliance are relatively complex to control, so the fault rate is high, the equipment structure and the technical principle are complex, so the manufacturing cost is high, and the requirement of high-precision weighing cannot be met by a simple vacuum suction machine.
2. The spiral quantitative packaging machine and the vibration quantitative packaging machine have a pure spiral structure, and adopt a vibration structure for blanking (the vibration amplitude and frequency are controlled by a microcomputer). These two products have 2 disadvantages:
firstly, the two have a common characteristic of 'ration', a fixed blanking weight needs to be set on a microcomputer control panel in advance, for example, 50g of powder medicine is produced in a factory, only 50g of powder medicine needs to be set in advance, and then the blanking operation is circulated. This is not suitable for a wide range of variable blanking operations, such as prescription blanking, by how much.
Secondly, the material weighing range is small, and 1 gram of material cannot be discharged by a machine capable of discharging 50kg under the condition of ensuring the precision, the speed and the equipment volume. The reason is that: (1) the screw of the screw quantitative packaging machine is too large, so that the powder with strong flowability flows out automatically, the equipment is too large, the screw is small, the rotating speed needs to be increased to ensure the blanking speed, but the high-speed rotation has the problem that the material cannot be discharged or the material properties are influenced due to heating; (2) the vibration type quantitative packaging machine has the problems of losing speed for precision (blanking is easy to be out of excess due to quick vibration), or overlarge volume (a plurality of vibration devices with different sizes and specifications) and quick vibration noise.
