Description
Technical Field
The invention relates to a spinneret plate cleaning device.
Background
The spinneret has a spinneret, and a thimble-like metal nozzle for spinning rayon has a plurality of small holes through which a spinning solution is extruded to form filaments. The raw material is melted or dissolved into viscous solution by a chemical method, and then the viscous solution flows out of a spinneret plate to form a filament, and the filament is solidified by condensation, evaporation or cooling. The spinneret is an essential precision part in a spinning machine as an important equipment for manufacturing synthetic fibers, and the size and shape of the spinneret are important conditions for ensuring the quality of a fiber finished product.
In the production process of synthetic fibers, polyester melt at 300 ℃ is rapidly sprayed out from micropores on a spinneret plate under the action of pressure and then cooled into filaments under the action of cooling air. In a production environment, after the spinneret plate works for a period of time, dirt formed by mixing crystals of polyester sublimate, degradation products, carbide and silicon oil (release agent) can be accumulated on the plate surface of the spinneret plate. After long-time accumulation, micropores on the plate surface of the spinneret plate can be blocked finally, the micropores are not sufficient in roundness or even completely blocked, and the problems of bending defects, broken filament defects and broken filaments appear on the silk threads.
At present, most factories manually clean dirt adhered to a plate surface by manpower, but the time consumption of manual cleaning is too long, the cleaning operation of workers is laborious, and the workers are easily injured due to high temperature in the environment where cleaning work is located.
In addition, some factories began to perform this laborious and dangerous work with a small number of automatic plate cleaners instead of manually. However, the existing automatic plate cleaning machine cannot be completely carried out under the working condition of the spinneret plate according to the technical defects, and the metering pump needs to be closed in the plate cleaning process (namely, the micro-holes do not eject the polyester melt). In the synthetic fiber production process, the pressure in the polyester raw material conveying pipeline is changed by repeatedly closing and starting the metering pump, so that the workshop production can be greatly caused, and meanwhile, the subsequent adjustment is also complex. Therefore, the problem of low plate cleaning efficiency also exists. In addition, such a so-called automatic cleaning process is not complete because the nozzle plate cannot be cleaned without wiping the plate after the scraping process is actually performed.
Therefore, aiming at the existing problems, the spinneret plate cleaning device which can automatically complete not only a shovel plate but also a wiping plate without closing a metering pump in the working process of a workshop and improve the efficiency of plate surface cleaning work has important significance.
Disclosure of Invention
In order to solve the problems, the invention provides a spinneret plate cleaning device, which can realize that a machine can complete a shovel plate without closing a metering pump in the working process through an uninterrupted shovel plate device, and automatically wipe the plate after the automatic shovel plate, so that the problem that the existing machine can not really replace manual scraping and shoveling to clean the plate surface, which wastes time and labor is solved, and the efficiency of plate surface cleaning work is improved.
In order to achieve the above object, the present invention provides a spinneret plate cleaning device, including:
the shovel plate device shovels the spinneret plate under the condition that the spinneret plate does not stop spinning;
the plate wiping device is used for wiping the plate after the spinneret plate is shoveled,
the blade device includes:
a slide rail;
the mechanical arm is arranged on the sliding rail;
the shovel plate device is arranged on the mechanical arm;
