Description
Technical field
The present invention relates to a kind of feed weighing devices, specifically a kind of compound automatic material weighing machine of drawer spiral.
Background technology
At present, feed weighing devices are broadly divided into following several：
1st, suction feeder, the device structure and electrical equipment control are more complicated, therefore its fault rate is high, the device structure and skill
Art principle is complicated, therefore its manufacturing cost is high, and simple suction feeder can not realize the requirement of high-precision weighing.
2nd, spiral quantitative package machine and vibration-type quantitative package machine, one is pure helical structure, and one is using vibrations
Structure carrys out blanking (micro computer control vibration amplitude and frequency).This two kinds of products have following 2 shortcomings：
First, the characteristics of the two has one jointly exactly " quantitative " in micro computer control panel, it is necessary to set solid in advance
Fixed cutting stock weight, such as the factory of production powder medicine, every bag quantitative 50 grams, it is only necessary to sets quantify 50 grams in advance, so
Posterior circle blanking operation.It is this to be not suitable for a wide range of variable amount of blanking operation, for example opened according to prescription blanking, prescription
It is how many just how much lower.
Second, weighing scope is small, and in the case where ensureing accuracy and speed and equipment volume, energy blanking 50kg machine
Cannot 1 gram of blanking.Reason is：1. the powder that the too conference of the spiral of spiral quantitative package machine causes mobility strong voluntarily flows
Go out, under it is excessive to also result in equipment, and spiral is small to be needed to improve rotating speed and just can guarantee that blanking velocity, but rotation can exist and expect at a high speed
Not the problem of not going or generate heat the character for influenceing to expect；2. vibration-type quantitative package chance has existed for precision and the (vibrations that lose speed
Blanking is caused easily to descend excess soon), or volume excessive (shaking devices of multiple different size specifications) and fast vibration
Noise problem.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of simple in construction, and small volume, fault rate is low, using flexible side
