Conveying roller gap adjusting device

Abstract

The invention discloses a transmission roller gap adjustment device, which comprises a bottom bracket, an upper pressure wheel, a lower roller, a U-shaped frame, a pressure plate, an adjusting screw, a fixed bearing seat, a movable bearing seat, and a spring. U-shaped frames are arranged on both sides of the bottom bracket, There is a U-shaped groove in the U-shaped frame, a pressure plate on the top, a fixed bearing seat on the bottom of the U-shaped groove, two positioning terminals on the upper end of the fixed bearing seat, a spring on the positioning terminal, a movable bearing seat on the spring, and a screw on the pressure plate. Hole 1 and screw hole 1 are provided with an adjusting screw rod, and the fixed bearing seat is provided with bearing hole 2, which is connected with the rolling bearing 2 on the shaft end 2 at both ends of the lower roller. The ball bearings on the shaft ends at both ends of the upper pressure wheel are connected, and four flat pads are arranged on the outside of the U-shaped groove, and the flat pads are connected to the U-shaped groove with fastening screws. The gap between the lower roller and the adjustment distance is controlled by a scale, which is suitable for conveying fabrics of different thicknesses.

Description

technical field [0001] The invention relates to a device for adjusting the middle gap of face cloth conveying rollers with different thicknesses, especially a device for adjusting the gap between conveying rollers. Background technique [0002] The rough face cloth is generally a large cloth roll, which needs to be divided into rolls of fixed length with a cloth rolling equipment. During the transmission process, it needs to be conveyed and supported by rollers. The transmission rollers are generally two upper and lower. The cloth passes through the gap in the middle of the drum, but different fabrics have different thicknesses. However, when the gap in the middle of the current drum is generally fixed, either the gap is too large, and the transmission of the cloth on the opposite side of the drum is easy to slip, or the gap is too small, and the cloth on the opposite side extrusion. Contents of the invention [0003] The object of the present invention is to overcome the...
