Embodiment Construction

[0034] Such as figure 2 The test device for the oiling performance of acetate fiber tow has an oil pump 12, an oil inlet conduit 13, and an oil tank 11 arranged in sequence according to the flow direction of the oil agent, and an oil tanker 5 next to the oil tanker 5 arranged in sequence according to the direction of transmission of the tow 1. The godet 2 on one side, the oiler 5, the godet 2 next to the other side of the oiler 5, the output roller 9; the oil tank 11 is filled with oil agent, and the oil tank 11 is connected with an oil level metering device 19. The included angle between the shaft center of the upper oil tanker 5 and the center of the godet 2 next to both sides is 150°-160°. There is a cylindrical capacitance tester 8 with a hole structure inside between the godet 2 and the output roller 9 next to the other side of the upper oil tanker 5; there is an upper scraper close to the upper oil tanker where the tow enters the upper oil tanker 5 The sheet 3 and the ...

Abstract

The invention discloses a device for testing the oiling performance of a cellulose acetate tow. The device comprises an oil pump, an oil inlet duct, an oil groove, a plurality of godets, an oiling wheel, an upper doctor blade, a lower doctor blade, a tester, an output roller, a control device and other components and parts, wherein the tester is a cylindrical capacitor which is provided with a hole in the interior, and the tow is conveyed out through the interior of the capacitor. The test method is as follows: when the tester detects the oiling rate of the tow is unqualified, the control device controls and adjusts the distance between the lower scraper and the oiling wheel through a doctor blade control line, and further controls the oiling amount of the tow. The rotating speed of the oiling wheel is 10-50r / min, and the rotating speed of the output roller is 400-850m / min. The device provided by the invention is reasonable in structure and convenient to operate, the oil-bring performance of the oiling wheel can be separately tested, the oiling performance of the tow can be detected on line, and the control and adjustment are accurate.

Description

technical field [0001] The invention relates to the process of adding lubricating oil agent to fibers and the equipment and process for testing the oiling rate. Background technique [0002] As we all know, in the production process of chemical fiber spinning, the tow needs to be oiled to improve the lubricity, cohesion, processing performance and use performance of the tow, and to eliminate static electricity. The type of oiling agent and the choice of oiling method have a very important impact on the spinning process and fiber quality. Most of the production technology of vinegar fiber used in domestic cigarettes adopts the method of oiling on tankers. [0003] With the continuous improvement and perfection of the industrial technology of acetate fiber spinning for cigarettes, the spinning speed has been continuously increased, and the requirements for the uniformity of oiling the filaments by the way of oiling the oil tanker are higher. In the production process, the ch...
