Abstract

A METHOD FOR CONTROLLING THE PROCESS OF PROCESSING THE FIBER MASS by periodically measuring the degree of electrification and breakage, characterized in that, in order to increase the efficiency of monitoring the process of obtaining a cotton tape on carding machines, the degree of electrification of the pulp at the entrance of the carding funnel is determined, the degree of electrification is dried. the minimum amount of breakage of the cotton ribbon is compared periodically measured by carding machines ization with a permissible value and performing a control process regime parameters on the carding machines, where the measured value of the electrification exceeds the permissible value.

Description

Fig.7 t The invention relates to the textile industry and is intended to control the processing of pulp. A known method is to control the processing of pulp by periodically measuring the degree of electrification and breakage. A disadvantage of the known method is the low speed of monitoring when identifying the causes of breakage of the material during operation of a large number of machines for the processing of pulp. The purpose of the invention is to increase the operability of controlling the process of obtaining cotton tape on carding machines. This goal is achieved by the fact that, according to the method for controlling the processing of pulp by periodically measuring the degree of electrification and breakage, the degree of electrification of the pulp at the entrance of the carding funnel is measured, the allowable value of the degree of electrification is determined by the minimum breakage rate of the cotton ribbon, periodically compared measured by the feeders, the degree of electrification with a permissible value and control of the process parameters at those carding machines where the measured value of the degree of electrization exceeds the maximum value of FIG. 1 is a diagram of the recycled pulp on the carding machine of FIG. 2-7 - dependence of the degree of electrification of the fibrous mass (intensity of the electrostatic field) on the technological and operating parameters of the process of processing the fibrous mass. The method is carried out as follows. The fibrous mass from the canvas 1 of the help of the carding mechanism 2 is processed into the web 3, which in the conical funnel 4 is collected into the tape 5. The latter is placed in the basin 6. The static electricity value is measured by the static electricity sensor 7. In the process 362 processing of the fibrous mass, it is electrified. The intensity of the floor of the electrostatic charge of the process at the site is the hack mechanism — the funnel is shown in FIG. 2. Increasing the degree of electrification of the process fluffs the material, which contributes to its breakage (fig.Z). The amount of electrification of the fibrous material is limited by the operational parameters of the process: humidity of the material (Fig.4), its processing speed (Fig. 3), humidity of the air in the workshop (Fig.6), constituent components of the material and their quality characteristics, for example: mass - maturity of cotton (Fig.7). Periodically, the degree of electrification of the fibrous mass at the entrance of the funnel of the combing machine and the number of material breaks are measured on the carding machines upon receipt of a cotton-tape, the allowable value Е of the degree of material electrification is determined by the minimum break of the cotton tape. The value of the degree of electrification in the periodic measurement of carding machines is compared with the permissible value of Units. If the measured value of the degree of electrification on some carding machines exceeds the allowable value of Units, then control the operating parameters (material moisture, processing speed, etc.) on the appropriate carding machines. The operation of measuring the degree of electrification of the pulp is carried out by a controller using an electrostatic charge meter. The permissible degree of electrification is determined by the type of pulp used by the equipment and processing technology. Thus, during processing of unpainted cotton on combing machines CTU1-4, the acceptable degree of electrification is 250 V / cm. The technical and economic effect of the use of the invention is determined by the efficiency of monitoring the process of obtaining cotton tape on carding machines.
