Photovoltaic glass raw material weighing device and method

Abstract

The invention provides a photovoltaic glass raw material weighing device and method. The photovoltaic glass raw material weighing device comprises: a material weighing cylinder, which is used for pre-loading a photovoltaic glass raw material to be weighed; a detection assembly, which is mounted on the wall of the material weighing cylinder and used for detecting the weight of the photovoltaic glass raw material to be weighed in the material weighing cylinder; and a correcting and weighing assembly, which comprises a hanging piece extending in a gravity direction, wherein the upper end of the hanging piece is connected to the wall of the material weighing cylinder, the lower end of the hanging piece is used for hanging a weight, and the detection assembly is further used for detecting the weight of the weight so as to judge an error range of the weight of the photovoltaic glass raw material to be weighed according to weight of the weight. According to the device and the method, the to-be-weighed photovoltaic glass raw material which is weighed for the first time can be precisely rechecked for the second time, various conditions such as weighing errors, material leakage, excessive material discharge, less material discharge and wrong material distribution can be effectively avoided, a material distribution period is shortened, and normal maintenance and repair of the device are facilitated.

Description

technical field [0001] The application belongs to the technical field of photovoltaic glass manufacturing, and more specifically relates to a photovoltaic glass raw material weighing device and method. Background technique [0002] In the production of photovoltaic glass, the weighing accuracy of raw materials is directly related to the production quality of the glass. Once an error occurs and the operator fails to find it in time, it will bring irreparable economic losses to the glass production. This phenomenon has always been The core focus of glass raw material batching. [0003] In the prior art, when the weighed raw materials meet the discharge conditions, the mixture will directly enter the mixer. For the occurrence of weighing errors, material leakage, multiple discharges, less discharges, and wrong mixes, etc., only rely on Manual observation and discovery cannot trace and track the weighing process. It can only be found when the batching report is checked after th...

[0002] In the production of photovoltaic glass, the weighing accuracy of raw materials is directly related to the production quality of the glass. Once an error occurs and the operator fails to find it in time, it will bring irreparable economic losses to the glass production. This phenomenon has always been The core focus of glass raw material batching

[0003] In the prior art, when the weighed raw materials meet the discharge conditions, the mixture will directly enter the mixer. For the occurrence of weighing errors, material leakage, multiple discharges, less discharges, and wrong mixes, etc., only rely on Manual observation and discovery cannot trace and track the weighing process. It can only be found when the batching report is checked after the batching is completed. However, at this time, the economic loss that cannot be returned to the production has been caused by the weighing error, which affects the stability of production. Hidden dangers

[0004] In addition, the batching cycle of the above-mentioned mixture is relatively long. According to the pulling capacity of 1000T / D, the capacity of the mixer is 7000L, and the daily batching is 120 batches, the average batching cycle is 7'30"-8'00" / payment.
