Description

Vibrating feeder

Technical field

The utility model relates to the technical field of industrial metrology, and more particularly to a vibration feeding device.

Background technique

In the industrial metering control industry, automatic weighing equipment is a commonly used metering equipment. The existing automatic weighing equipment mainly includes a feeding device, a metering device and a control device. Wherein, the feeding device is used for conveying the material into the metering device, the metering device is equipped with a sensor, and the sensor can return the weight signal to the control device, and the control device further controls the feeding speed of the feeding device, for example, is divided into fast feeding, The medium speed feed and the slow feed feed three different speeds, so that the feeding device is conveyed at different feed speeds at different stages, and when the predetermined value is reached, the feeding device stops feeding. At this time, in the feeding device, the material discharge port of the trough naturally slides down into the metering device due to inertia and gravity, which affects the measurement accuracy. When performing the above weighing control, it is of course desirable that most of the time is in the fast feeding phase, which can shorten the overall quantitative time and improve efficiency. However, the higher the feed rate, the greater the deviation of the slip material, resulting in the switching control point from the fast feed to the medium feed, the medium feed to the slow feed is not easy to control, so generally can only be reduced The material weight of the fast feed (reducing the time of fast feed) increases the time of medium feed and slow feed to improve control accuracy.

For example, 5 kg of packaged rice commonly found in supermarkets is generally packaged after weighing in the manner described above. In the weighing process, it is usually desired that all 5 kg is completed by rapid feeding, so that the overall time is short, but if the speed is too fast, the meter slips when stopped, resulting in poor metering accuracy. Therefore, it is usually done by using the fast feeding method to complete the feeding of more materials, and the remaining part is completed by the slow feeding. At this time, the stopping point of the fast feeding is very important, if the fast feeding ends each time. When the weight of the conveyance is not much different, the equipment can be better adjusted, so that most of the materials are completed by rapid feeding, and it can better judge the cause of gravity at the end of the slow feeding. The weight of the material slips, thereby improving the overall accuracy and speed.

In view of this, it is necessary to provide a feeding device which can improve the problem of material slippage to solve the above technical problems.
