Description

Technical Field

[0001] The present invention relates to the technical field related to roll replacement, and particularly to a roll press convenient for roll replacement. Background Art

[0002] A roll, also known as a roller, is a cylindrical part, divided into a driving roll and a driven roll. It is widely used in various transmission and conveying systems such as rotary screen printing machines, digital printers, mine conveying equipment, papermaking and packaging machinery, etc.;

[0003] The existing Chinese patent document with the publication number CN117504980B discloses a roll press convenient for roll replacement. Its solution includes two roll replacement mechanisms, and lubricating oil heat dissipation mechanisms are arranged at the ends of both roll replacement mechanisms. The roll replacement mechanism includes two extrusion rolls. At the central positions of both extrusion rolls, a second rotating shaft is fixedly connected. At one end of both second rotating shafts, a first self-locking disc is fixedly connected. At the other end of both second rotating shafts, a telescopic sleeve shaft is fixedly connected. At the ends of both telescopic sleeve shafts, a bearing plate is fixedly connected. A limiting ring is rotatably sleeved outside both bearing plates. A rotating plate is fixedly connected between both limiting rings. At the central position of the outer wall of the rotating plate, two connecting plates are symmetrically and fixedly connected. A linkage disc is fixedly connected between the ends of both connecting plates. A spiral surface ring is fixedly connected to the outer wall of the linkage disc. A linkage shaft is rotatably sleeved at the central position of the linkage disc. A U-shaped seat is rotatably sleeved on the outer wall of the linkage shaft.

[0034] Active rollers 2 and driven rollers 3 are provided on both sides of the roller press frame 1, and the corresponding active rollers 2 on both sides are installed on the same active rotating shaft 4. The upper bearing positioning mechanism is connected to the roller press frame 1 through an elastic connecting member 21, and when the workpiece to be processed passes through the active roller 2 and the driven roller 3, the elastic connecting member 21 is in a compressed state, and the elastic support of the elastic connecting member 21 ensures that the active roller 2 and the driven roller 3 are stably stressed.

[0035] A positioning protrusion 9 is integrally formed on the side wall of the mounting hole 8 on the active roller 2, and a guide groove 10, a steering groove 11 and a positioning groove 12 are provided on the side wall of the active rotating shaft 4. The positioning protrusion 9, the guide groove 10 and the positioning groove 12 are symmetrically arranged in a group, and the guide groove 10 and the positioning groove 12 are arranged in a cross shape, and the cross-sectional dimensions of the guide groove 10 and the positioning groove 12 are consistent, and the guide groove 10 and the positioning groove 12 are connected to the steering groove 11.
