Problems solved by technology

However, during the long-term use of the unit, due to the loosening and wear of the tensioning wheel, uneven force will occur during the rotation process. The traditional tensioning device is not easy to adjust, and the transmission chain of the tensioning wheel becomes loose or deflected. thus skewing the transmission

Abstract

The invention relates to a conveyor chain tensioner comprising a mounting plate, a tensioning bracket, a tensioning screw, set blocks, nuts, a short shaft and a chain wheel. A row of equidistant threaded holes are formed in the mounting plate; the tensioning bracket is composed of a bottom plate, two side plates and two retaining plates; two sliding grooves are formed in the bottom plate of the tensioning bracket, and the mounting plate and the tensioning bracket are connected in sliding fit; threaded holes are formed in the retaining plates at two ends of the tensioning bracket, and the tensioning screw penetrates the set blocks and the retaining plates, one nut is arranged on each side of each set block, and the tensioning screw are fixed on each set block through the two nuts; the tensioning bracket, the short shaft and the chain wheel are adjusted in position relative to the mounting plate through the tensioning screw and the nuts and are fixed through bolts. The conveyor chain tensioner has the advantages that the conveyor chain tensioner can keep proper tension of a chain so as to prevent the chain from shaking and is convenient to adjust and reliable in fixation, and accuracy and stability of conveyor operation are guaranteed.

Description

technical field [0001] The invention relates to the technical field of conveying machinery, in particular to a conveyor chain tensioning device. Background technique [0002] The tensioning wheel is a device used for chain drive tensioning. When the center distance of the conveyor chain cannot be adjusted, the tensioning wheel can be used to tension the belt to prevent poor meshing and chain vibration. Tensioner pulleys are used in large units used in the manufacturing industry, and the tensioner pulley can adjust the tightness of the conveyor chain. However, during the long-term use of the unit, due to the loosening and wear of the tensioning wheel, uneven force will occur during the rotation process. The traditional tensioning device is not easy to adjust, and the transmission chain of the tensioning wheel becomes loose or deflected. As a result, the transmission deviates. Contents of the invention [0003] The present invention aims to solve the above-mentioned shortc...
