Device for improving quality of end part of borosilicate glass tube

The scheme relates to a device for improving the end part quality of borosilicate glass tubes in the field of glass manufacturing, the device comprises a conveying chain and conveying plates, the conveying plates are vertically fixed on the surface of the conveying chain in parallel, and two adjacent conveying plates form a gap for accommodating the glass tubes; at least two conveying chains are arranged in parallel, the lower portions of the conveying chains are supported through the rack, a friction strip is arranged between the two parallel conveying chains and fixed to the rack, the feeding end of the friction strip is higher than the upper surfaces of the conveying chains, and the other end of the friction strip is lower than the upper surfaces of the conveying chains. A guide inclined surface is arranged on the end surface of the feeding end of the friction strip; the device solves the problem of subsequent deformation caused by non-uniform heating temperature of the glass tube, and has higher populariz
