Dry material metering controller

The invention relates to a dry material metering controller, in particular to a weight measuring device and an arc-shaped flow guiding frame arranged in the casing, and the arc-shaped design of the curved guiding frame is used to temporarily carry the dry material in the curved guiding flow. On the rack, the weight of the dropped dry material is immediately calculated by the weight meter, and the dry material in the curved deflector is guided along the arc-shaped flow guide to the discharge port of the chassis to continuously Dry material metering controller for continuous feeding and metering.

According to the conventional measuring device for dry materials, such as the device for metering dry and/or flowable powdery substances in Taiwan No. 152317, a closed valve body 12 is disposed on the lower side of the container 8 to transport the material, and A day scale is placed below the outlet of the valve body 12 to measure the amount of application of the rotary conveyor by the container outlet to utilize the container 8 to remove the count of powdered material very accurately without erroneous metering.

Further, the "Measuring Device of a Packaging Machine" of Taiwan No. I271355 is provided with a container 10 for feeding the raw material onto a conveyor belt 20 which can be driven by the motor 30 to convey the dry material. To the end of the conveyor belt 20, and then falling down into the weighing hopper 60, the weighing hopper 60 is connected at one end to the load source 50 to weigh the weighing hopper 60 and the dry material contained therein, when the dry weight reaches the preset After the weight, the solenoid valve 70 of the hopper 60 can be actuated to pull the pull rod 71. The pull rod 71 can open the weighing hopper 60 and drop the dry material in the weighing hopper 60 downward, so as to facilitate the subsequent packaging into a bag. .

However, the above-mentioned conventional dry material metering device is applied to measure a fixed weight dry material to obtain a fixed weight dry material, and the dry material satisfying the weight condition is followed. The above-mentioned conventional dry material metering device can separately measure the dry materials one by one, but for a large amount of dry materials that need to be continuously metered, it is impossible to continuously measure, and the raw material is adjusted instantaneously, for example, in a large number of adjustments. When the ratio of feed, food or chemical materials is less than the amount of raw materials required, it is difficult to complete the blanking operation quickly and continuously, so the conventional person must calculate the amount of raw materials required in advance. Then, the raw materials are poured into the raw material cylinder one by one, and then the raw material is used for the blanking operation. If the proportion of the raw materials is temporarily changed, the amount of the original amount needs to be re-adjusted, which is very labor-intensive and trouble-prone, and is not practical. Sex.
