Description

Technical Field

[0001] The utility model relates to the technical field of papermaking equipment, and more specifically to a round screen former for papermaking. Background Art

[0002] In the field of papermaking, board paper (or paperboard) is generally produced by a multi-cylinder papermaking machine or a stacked papermaking machine. The sizing system of the multi-cylinder papermaking machine has various forms such as movable arc plate mesh trough and pressure spraying on the net forming. The paperboard made by the movable arc plate mesh trough sizing system has a large difference in longitudinal and transverse tensile force when the pulp is put on the net, and the fibers arranged in the transverse and Z directions are relatively small. Therefore, the paperboard produced has a large difference in longitudinal and transverse tensile force, and the interlayer bonding strength of the paperboard is poor. When the pressure spraying is used on the net, the pulp fibers are arranged in disorder in the longitudinal, transverse and Z directions, and the produced paperboard overcomes the problem of In order to overcome the above shortcomings, the pulp screen system of the rotary screen papermaking machine currently mostly adopts a pressure spraying screen forming device; the rotary screen pressure spraying screen forming device is generally composed of a square cone pulp inlet pipe, a number of straight-through sizing hoses evenly distributed on the square cone pipe, a former frame, a slurry groove, a pulp baffle, a lip skin, an upper lip plate, an adjusting screw, etc.; the slurry supply form of the general rotary screen is that the slurry is fed from the inlet (the thick end) of the square cone pulp inlet pipe and the outlet (the thin end) is refluxed, and a number of straight-through sizing hoses evenly distributed on the square cone pipe are used to realize multi-tube slurry distribution.

[0003] After searching, a papermaking cylinder former disclosed in publication number CN213417422U includes an upper lip plate, a fixing column is integrally formed on the upper lip plate, a threaded column is integrally formed at one end of the fixing column, a connecting tube is threadedly connected to the threaded column, a rotating round block is movably provided in the connecting tube, and a connecting column is integrally formed on one side of the rotating round block, a connecting thread is provided, an outer wall of the connecting column is provided with a connecting thread, the connecting column is threadedly connected to one end of an adjusting screw, a threaded hole is provided on the end face of one end of the adjusting screw, and a rotating disk is integrally formed at the other end, positioning grooves are equidistantly provided at the side positions of the adjusting screw, and the adjusting screw is penetrated in the support plate, the support plate is integrally provided with a fixing block at the side position of the adjusting screw, and a T-shaped movable block is movably connected in the fixed block.

[0004] The above-mentioned technical solution has certain beneficial effects, but in actual use, since the end of the T-shaped movable block and the positioning slot will not move horizontally with each other, but can move longitudinally with each other, the adjustment screw moves inside the support plate, which will still cause the position of the upper lip plate to shift. For this reason, we propose a round screen former for papermaking. Utility Model Content
