Description

Special-shaped spinneret plate quick-change device Technical Field The utility model belongs to the technical field of spinneret plates, and particularly relates to a special-shaped spinneret plate quick-change device. Background The spinneret plate is a core component in chemical fiber production, and has the core function of converting a high polymer melt or solution into a thin flow with a specific section through micropores, and solidifying the thin flow through a solidification medium to form fibers. Some of the spinneret holes are different from the traditional spinneret holes, and are also called profiled spinneret plates. At present, the Chinese utility model with the bulletin number of CN215856479U discloses a replaceable spinneret plate convenient for positioning and splicing. The existing special-shaped spinneret plate is generally installed in a bolting mode, so that the special-shaped spinneret plate can be detached, maintained or replaced. However, when the screw is replaced, the screws are required to be unscrewed and re-screwed one by one, so that the operation is troublesome, and the replacement efficiency of the special-shaped spinneret plate is affected. Meanwhile, when the existing special-shaped spinneret plate sprays the fiber, the spinning liquid is directly blown and shaped from the side edge of the spinneret hole before the fiber is sprayed. However, the operation mode needs to control the air quantity of the hot air properly, and if the air quantity control is not good, the linear molding deflection of the spinning at the un-perforated line can be caused, and even the possibility of the wire explosion occurs, so that the molding effect of the spinning and the quality of the fiber yarn are reduced. Disclosure of utility model The utility model aims to provide a quick-change device for a special-shaped spinneret plate, which has the advantages of being convenient for quick change of the special-shaped spinneret plate, avoiding hot air from directly contacting with fiber yarns, and improving the shaping effect before the fiber yarns are sprayed out. The technical aim of the utility model is achieved through the following technical scheme that the special-shaped spinneret plate quick-change device comprises a mounting seat, wherein a spinneret plate main body is connected inside the mounting seat in a sliding manner, a first gear is connected inside the inner wall of the mounting seat in a rotating manner, a threaded rod which is in threaded connection with the spinneret plate main body is welded at one end of the first gear, which is close to the spinneret plate main body, an annular plate which is in threaded connection with the mounting seat in a rotating manner is sleeved on the surface of the first gear, an inner ring annular rack which is meshed with the first gear is welded on the inner surface of the annular plate, an outer ring annular rack is welded on the outer surface of the annular plate, and a second gear which is meshed with the outer ring annular rack is connected on the other side of the inner wall of the mounting seat in a rotating manner. By adopting the technical scheme, the second gear is meshed with the outer ring annular rack on the surface of the annular plate through rotation, so that after the outer ring annular rack is meshed with the first gear again through the inner ring annular rack, all threaded rods inside the mounting seat are uniformly driven to be meshed with threads of the spinneret plate main body. Therefore, the spinneret plate main body can be quickly assembled and disassembled from the inside of the mounting seat, the bolts cannot be twisted one by one, and the efficiency is improved. High-temperature hot air is blown into the hot air tank through the hot air inlet, and meanwhile, the heat absorbing cylinder blocks the hot air and transfers the heat of the hot air to the textile yarn liquid for plasticity after absorbing the heat of the hot air. Therefore, the shaping effect before the fiber is ejected can be improved, the hot air is prevented from directly contacting the fiber, and the practicability of the spinneret plate is improved. The utility model is further characterized in that a hot air inlet is formed in the bottom of the mounting seat, a hot air groove communicated with the hot air inlet is formed in the spinneret plate main body, a spinneret orifice is formed in the spinneret plate main body, and a heat absorption cylinder is welded at one end of the surface of the spinneret orifice, which is positioned in the hot air groove. By adopting the technical scheme, the shaping effect before the fiber is ejected can be improved, the hot air is prevented from directly contacting the fiber, and the practicability of the spinneret plate is improved. The utility model is further characterized in that a filament liquid port is formed in one end, far away from the spinneret plate main body, of the installation seat, and a liquid homogenizing gro
