Conveying and metering device for automatic cutting machine

Abstract

The invention discloses a conveying and metering device for an automatic cutting machine. The conveying and metering device comprises a large bottom plate, a feeding mechanism and a metering mechanism. The feeding mechanism comprises a first bracket, a driving roller and a driven roller, the first bracket is arranged in the middle of the large bottom plate, and the driving roller is arranged on the lower portion of the first bracket. The driven roller is located over the driving roller, the two ends of the driven roller are provided with adjustment blocks, and the adjustment blocks are in sliding connection with the first bracket. The two side of the top plate are provided with first air cylinders correspondingly, the telescopic ends of the two first air cylinders are connected with the driven roller and stretch out and draw back synchronously. The metering mechanism comprises a second bracket, a lower driven wheel and an upper driven wheel. The second bracket is located on the rear side of the first bracket. The lower driven wheel is installed on the second bracket. An encoder is connected to one side of the lower driven wheel. The upper driven wheel is arranged on the first bracket through an L-shaped bracket. The conveying and metering device is reasonable in structural design and high in practicability and accuracy, and the problem that metering is inaccurate due to relative sliding friction between a silicon steel belt and the driving roller is solved.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a conveying and metering device for an automatic cutting machine. Background technique [0002] At present, the equipment and processing technology used for cutting silicon steel sheets are outdated, and the feeding and conveying mechanism of silicon steel strips uses conveying equipment to feed materials. Usually, the feeding length of silicon steel strips is measured according to the conveying rollers. There will be a relative displacement between the silicon steel strip and the silicon steel strip due to the drive, resulting in an error in the cutting position of the subsequent cutting unit for the silicon steel strip, the cutting accuracy is not high, and certain waste products appear. It is difficult for the old cutting equipment to ensure that the silicon steel material belt is transported forward along the forward direction during the material belt conveying process. T...

Problems solved by technology

[0004] Aiming at the deficiencies of the above-mentioned prior art, the present invention proposes a conveying metering device for an automatic cutting machine, the purpose of which is to solve the gap between the conveying roller and the silicon steel strip during the feeding process of the silicon steel strip. Relatively sliding, resulting in inaccurate measurement of the feed length of the silicon steel strip, resulting in a high scrap rate of the product
