Compact accuracy metering device

Abstract

The invention discloses a compact accuracy metering device, and the device comprises a feed hopper, electromagnetic heating apparatuses, a main frame, a weighing sensor, and a laying-off nozzle. The top of the main frame is provided with a feeding port, and the feed hopper is disposed on the feeding port. The interior of the main frame is provided with a conveying belt, and the bottom of the main frame is provided with a discharging port. The laying-off nozzle is disposed on the discharging port, and materials entering from the feeding port are conveyed to the discharging port through the conveying belt. The electromagnetic heating apparatuses are uniformly installed and distributed on the feed hopper. The weighing sensor is disposed at the bottom of the main frame. The device employs the technology of electromagnetic heating, reduces the size, reduces the machining difficulty and cost, and avoids a mechanical fault.

Description

technical field [0001] The invention relates to a material pretreatment device, in particular to a compact and precise metering device. Background technique [0002] In industrial production, it is often necessary to measure the weight of raw materials before reacting to achieve accurate quantitative production. In addition, some raw materials need to be preheated before reacting. For example, plastic raw materials need to be preheated during the production of plastic products. Heat and load bearing, Chinese invention patent 201520030324.0 discloses a rapid preheating accurate metering device, which includes a feed hopper 1, a main frame 2, a radiation heating device 24, a conveyor belt, a metering mechanism 8 and a driving mechanism 7, inside the main frame It is a heating chamber, the top is a radiant heating device 24, and the bottom is a support plate 26. Two pairs of rotating shafts 23 are installed in the heating chamber. The feeding hopper 1 is installed on the main ...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the upper conveyor belt 21 and the lower conveyor belt 22 are used for double-sided preheating, the main body frame 2 has a large volume and needs to occupy a large space on the production line.

[0005] Two, there are many components in the main body frame 21, and the structure is quite complicated, the processing difficulty is relatively large, and the cost is high;

[0006] 3. Preheating on the conveyor belt. When overheating occurs, it is easy to cause the plastic material to bond with the conveyor belt, causing the conveyor belt to be stuck, and even cause the entire device to malfunction.
