The utility model is mainly composed of a groove type supporting roller group, a plurality of parallel supporting roller groups, various types of self-aligning roller groups, and various buffer supporting roller groups.
(1) the trough type roller has the common type supporting roller, the forward type supporting roller, the quick change bearing type supporting roller, the hanging type supporting roller, the three chain supporting roller, the reversible supporting roller, the changing groove angle supporting roller, the transition type supporting roller, the V type supporting roller, etc.;
(2) the parallel roller has the common type supporting roller, the comb type supporting roller, the forward type supporting roller, the steel glue type supporting roller, the spiral supporting roller, etc.;
(3) the centering roller has the general type, the friction reversible type support roller, the strong type supporting roller, the cone supporting roller, the spiral type supporting roller, the combined supporting roller and so on;
(4) the buffer roller has a spring plate supporting roller, a buffer ring type supporting roller, a strong buffering supporting roller, an adjustable elastic supporting roller, a hanging supporting roller, etc.;
The roller parts 1, roller bearing stamping: roller bearing seat is divided into two kinds, one is pressing bearing seat, a bearing seat (gray cast iron). Most of the stamping bearing seat is welded with the steel pipe. Stamping bearing seat is characterized by good sealing, the overall bearing capacity, the biggest feature of cast iron bearing seat is a high degree of concentricity, but the bearing capacity is lower than the bearing seat. 2, roller bearing: bearing is the most important part of the roller, bearing directly affects the service life of roller. Therefore, the selection of roller bearings, than to choose other roller accessories more cautious. 3, roller seal: roller sealing material is divided into polyethylene and nylon. Polyethylene and low cost, but the wear resistance is relatively poor, on the contrary, the sealing cost of nylon material is relatively high, but the high wear resistance (to identify whether the nylon material, can be sealed into the water, the sinking of the nylon material is sealed, floating on the surface of polyethylene material is sealed). Roller seal according to the type of roller is divided into TD75 type, DTII type, TR type, TK type, QD80 type, SPJ type and so on nearly ten kinds. 4, roller shaft: roller shaft is divided into cold drawn steel shaft and ladder shaft. Note: the tolerance of roller shaft must be guaranteed between 0.002mm-0.019mm. 5, the card spring: roller selection of the spring is made of spring steel, play the role of fixed roller string. Poor elasticity of the spring, volatile, in the external force of the press can not be a good prevention and control of the string. 6, ring: the shaft part of the fixed into the axial and circumferential fixed.
