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 and 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 certain...

Abstract

The invention discloses a metering control system and relates to the technical field of spinning machines. The metering control system aims to solve the problems that in an existing color master batch metering and adding device, because the signal delay effect exists among a metering pump, a control unit and a color master batch metering device, color master batch metering accuracy can not be ensured. The metering control system comprises at least one metering pump, a color master batch adding device and an extruder, wherein the color master batch adding device and the extruder are respectively connected with the metering pumps, and a color master batch frequency converter connected with a color master batch feeding motor is arranged in the color master batch adding device. The metering control system further comprises an extruder frequency converter and a start-stop signal processor, wherein the extruder frequency converter is connected with an extruder motor in the extruder, and the start-stop signal processor is respectively in signal connection with the metering pumps, the extruder frequency converter and the color master batch frequency converter. The metering control system is especially suitable for the 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...
