Detailed Description
The present invention is further illustrated in detail below with reference to examples:
as shown in fig. 1 and 2, the pre-loosening feeding device for the machine yarns comprises a transmission mechanism of the yarn bundles, a storage box 1, an online monitoring mechanism of the yarn bundles arranged in the storage box 1 and a control cabinet 2, wherein the storage box 1 is arranged between the transmission mechanism and an inlet of a forming machine 4 of the yarn bundles, the storage box 1 is of a closed cuboid hollow box structure, a yarn bundle inlet and a yarn bundle outlet are arranged at two ends of the upper surface of the storage box 1, a yarn bundle drooping space is arranged in the storage box 1 between the yarn bundle inlet and the yarn bundle outlet, the machine yarns droop and store in the storage box 1 before entering the forming machine 4, the machine yarns are pulled mutually by self gravity, the compacted machine yarns are restored to a loose state by pulling, and the probability that waste products are generated after the machine yarns enter the forming machine 4 is reduced.
The transmission mechanism comprises a driving rotating shaft 9 and a driven rotating shaft 10, the driving rotating shaft 9 is in line contact fit with the driven rotating shaft 10 and is used for transmitting tows in the raw material stack into the storage box 1, the driving rotating shaft 9 is driven by the servo motor 3, and the transmission mechanism and the servo motor 3 can be arranged on a fixed support on the storage box 1. Preferably, the driving rotating shaft 9 and the driven rotating shaft 10 are arranged up and down, the driving rotating shaft 9 is arranged on the lower side, and the driven rotating shaft 10 is arranged on the upper side, so that the transmission error and the slip probability are reduced. On-line monitoring mechanism includes velometer 5, upper sensor 11 and lower sensor 12, velometer 5 sets up on 1 inner wall of storage tank of the lower extreme of silk bundle export, and velometer 5 is used for detecting the translation rate of silk bundle, and upper sensor 11 and lower sensor 12 set gradually on 1 lower part inner wall of storage tank from top to bottom, and upper sensor 11 and lower sensor 12 are infrared ray sensor, and upper sensor 11 and lower sensor 12 are used for detecting flagging silk bundle bottom position.
The control cabinet 2 comprises a touch screen 6, a PLC7 and a servo controller 8, the touch screen 6, the velometer 5, the upper sensor 11 and the lower sensor 12 are all connected with the input end of the PLC7, the output end of the PLC7 is connected with the servo controller 8, and the servo controller 8 is connected with the servo motor 3. The speed that velometer 5 surveyed is tracked to the servo motor 3 of switch board 2 control for the tow that storage tank 1 tow export was come out keeps balance with the tow that gets into from storage tank 1 tow import, guarantees the length of tow in storage tank 1, guarantees tow flagging length promptly, makes the completion that the tow in storage tank 1 can be better drag the pine.
The flagging height decision silk bundle of silk bundle in reserve tank 1 drags loose quality, flagging silk bundle bottom is low excessively probably leads to the silk bundle to be dragged too loosely, flagging silk bundle bottom is too high probably leads to the silk bundle each other draw power less even break, can not reach the effect of dragging loosely, consequently the lower part at reserve tank 1 inner wall is provided with upper sensor 11 and the lower sensor 12 that detect the position of flagging silk bundle bottom, be arranged in monitoring reserve tank 1 flagging silk bundle whether between upper sensor 11 and lower sensor 12, so that in time make the adjustment to servo motor 3's rotational speed. The positions of the upper sensor 11 and the lower sensor 12 are set by the worker according to the working experience, the bottom end of the drooping tows can be pulled loose to achieve the best effect in the interval, the tows stored in the storage box are prevented from being too few, and the tows stored in the storage box are prevented from being too much to cause stacking in the storage box 1.
Meanwhile, in the using process of the invention, the servo controller 8 controls the servo motor 3 to always run at the same speed as that measured by the velometer 5, but with long-time use, the tows between the driving rotating shaft 9 and the driven rotating shaft 10 are difficult to avoid slipping or the tows are not necessarily strictly transmitted according to the rotating speed of the servo motor 3, and long-time error accumulation causes the bottom end of the sagging tows not to be always kept between the upper sensor 11 and the lower sensor 12, so that the arrangement of the upper sensor 11 and the lower sensor 12 is particularly important, and the functions of double insurance and error correction are achieved.
