Embodiment Construction

[0022] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0023] combine figure 2 with image 3 Illustrate the working principle of the metering and adding system of the color masterbatch of the present invention. In the production process of producing polyester colored filaments, the main material and the color masterbatch are dried respectively through the main material dryer 1 and the color masterbatch dryer 2. After being metered by the masterbatch metering device 3, the processed color masterbatch is mixed with the main material according to a certain ratio, and is squeezed and melted by the extruder 4 and then enters the metering pump 5. Since one main material dryer 1 and one masterbatch dryer 2 need to supply multiple metering pumps 5 to work, in order to ensure that the addition ratio of color masterbatch in each metering pump 5 is consistent, when a certai...

Abstract

This patent discloses a metering control system, which relates to the technical field of spinning machines. In the existing color masterbatch metering and adding device, there is a signal delay effect between the metering pump, the control unit and the color masterbatch metering device, which cannot ensure the accuracy of the color masterbatch metering. It includes at least one metering pump, a color masterbatch adding device and an extruder respectively connected with the metering pump, a color masterbatch frequency converter connected with a color masterbatch feeding motor is arranged in the color masterbatch adding device, and it also includes a An extruder frequency converter connected with the extruder motor in the extruder; a start-stop signal processor, which is respectively connected to the metering pump, the extruder frequency converter and the color masterbatch frequency converter. The invention is especially suitable for use in spinning machines.

Description

technical field [0001] The invention relates to the technical field of spinning machines, in particular to a metering and adding control system for spinning. Background technique [0002] Spinning is a key process in the production process of chemical fibers. It is to continuously, quantitatively and uniformly extrude the spinning fluid or melt from the capillary holes of the spinneret or spinneret with a spinning pump (or metering pump). The process of forming a liquid stream and then solidifying into a filament in air, water or coagulation liquid. In the process of producing colored polyester filaments, in addition to conveying the polyester raw materials to the hopper of the extruder through the spinning metering pump, it is also necessary to add the required color masterbatch to the polyester raw materials through the feeder. [0003] At present, the control signal of the masterbatch metering device in the spinning machine is mostly taken from the extruder speed, that i...
