Accurate metering device capable of achieving rapid preheating

Abstract

The invention discloses an accurate metering device capable of achieving rapid preheating. The accurate metering device comprises a feeding hopper, a main frame, radiant heating devices, a conveying belt, a metering mechanism and a drive mechanism, wherein a heating cavity is arranged inside the main body; one radiant heating device is arranged on the top of the main frame; a supporting board is arranged at the bottom of the main frame; two pairs of rotary shafts are installed inside the heating cavity and connected with the drive mechanism; another radiant heating device is also arranged between the two pairs of rotary shafts; the feeding hopper is installed at the upper end of the main frame; the conveying belt comprises an upper conveying belt and a lower conveying belt which are installed on the two pairs of rotary shafts of the main frame respectively; the upper conveying belt and the lower conveying belt are parallel and opposite in conveying direction; the metering mechanism comprises a weighing sensor, a data conversion module and a tray; the upper end of the weighing sensor is installed on the supporting board at the bottom of the main frame; the tray is installed at the lower end of the weighing sensor; the data conversion module is electrically connected with the weighing sensor. The accurate metering device capable of achieving rapid preheating achieves rapid preheating and accurate metering of materials, lowers the use cost of equipment, and improves production efficiency.

Description

technical field [0001] The invention relates to a material pretreatment device, in particular to a fast preheating and accurate 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 and Weighing, in the prior art, the weighing and preheating of general raw materials need to be carried out step by step, and special preheating devices and metering devices are required, which not only takes more time, but also requires more equipment costs, For modern industrial production that emphasizes high efficiency and low cost, the existing raw material preheating and weighing devices can no longer meet the requirements. [0003] In view of this, the inventor specially developed a device that simultaneously realizes rapid pr...
