Detailed Description

The technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments described in the present disclosure, all other embodiments obtained by a person skilled in the art without creative efforts are within the scope of the present disclosure.

The embodiment of the utility model provides a yarn conveying device for detecting yarn scab is shown in figures 1 to 2, and comprises a fixed frame 1 and a first yarn guide eye 2, wherein the first yarn guide eye 2 is fixedly connected to the fixed frame 1, the lower end of the fixed frame 1 is provided with a yarn guide frame 3 and a yarn conveying wheel 4, the yarn guide frame 3 is provided with a yarn guide rod 5, the bottom end of the yarn guide rod 5 transversely slides to form a yarn collision sleeve 6, the fixed frame 1 corresponding to the collision sleeve 6 is provided with an alarm sensor, and the alarm sensor is electrically connected with an indicator light; vertical plates 7 are fixedly mounted at two ends of the abutting sleeve 6 respectively, the vertical plates 7 are perpendicular to the plane of the abutting sleeve 6, an infrared sensor 8 for detecting scabs of yarns is mounted on the inner side wall of each vertical plate 7, the infrared sensor 8 is electrically connected with the alarm sensor, a space for the abutting sleeve 6 to slide left and right is further arranged in the yarn guide frame 3, a groove 9 for placing a magnet is formed in a contact part of the yarn guide rod 5 and the abutting sleeve 6, a first magnetic block 10 is arranged in the groove 9 of the yarn guide rod 5, a second magnetic block 12 is arranged in the groove 9 of the abutting sleeve 6, and opposite surfaces of the first magnetic block 10 and the second magnetic block 12 are homopolar; when the yarn deviates, the friction force between the yarn and the abutting sleeve 6 is greater than the friction force between the abutting sleeve 6 and the yarn guide rod 5, the yarn drives the abutting sleeve 6, and the abutting sleeve 6 drives the vertical plate 7 to deviate on the yarn guide rod 5 in the transverse direction.

The fixed frame 1 is also provided with a rotating wheel 13 and a bending rod 14, and the bending rod 14 is used for guiding the yarn to pass through the rotating wheel 13.

Two driving belt pulleys 15 are arranged on the fixing frame 1, the two driving belt pulleys 15 are connected through a clutch 16, and the driving belt pulleys 15 are coaxially connected with the yarn conveying wheel 4.

The groove 9 of the yarn guide rod 5 is divided into a yarn guide rod upper groove 91 and a yarn guide rod lower groove 92, and the groove 9 of the interference sleeve 6 is divided into an interference sleeve upper groove 93 and an interference sleeve lower groove 94.

Because conflict cover 6 cup joints the slip on yarn guide 5, the upper portion of conflict cover 6 separately is equipped with conflict upper groove 93, it is yarn guide upper groove 91 to correspond to overlap upper groove 93 laminating with the conflict, be equipped with second magnetic path 12 in the conflict upper groove 93, be equipped with first magnetic path 10 in the yarn guide upper groove 91, because the opposite face of first magnetic path 10 and second magnetic path 12 is homopolar, lead to like polarity to repel, make and do not have direct contact's state between conflict cover 6 and the yarn guide 5, can reduce the frictional force between conflict cover 6 and the yarn guide 5. The second magnetic block 12 and the first magnetic block 10 are also respectively arranged in the lower groove 92 of the yarn guide bar and the lower groove 94 of the interference sleeve, and the lower groove 92 of the yarn guide bar and the lower groove 94 of the interference sleeve ensure the stability of the interference sleeve 6 under the condition that the yarns are not deviated.

The yarn guide frame 3 is further provided with a hollow loop bar 17, the loop bar 17 is provided with a second yarn guide eye 18 and a third yarn guide eye 11, and the yarn guide bar 5 and the yarn guide sleeve are located between the second yarn guide eye 18 and the third yarn guide eye 11.

The infrared sensor 8 comprises an infrared receiver 81 and an infrared transmitter 82, the infrared receiver 81 and the infrared transmitter 82 adopt correlation type sensors, and when the infrared receiver 81 receives a signal of the infrared transmitter 82, the alarm sensor does not alarm; when the infrared sensor 8 does not receive the signal of the infrared transmitter 82, the alarm sensor gives an alarm.

Because the yarn only has a yarn to exist through conflict cover 6, nevertheless because the yarn can take place horizontal skew left or right owing to reasons such as tension, and riser 7 and conflict cover 6 fixed connection for certain slip space is required when riser 7 is following conflict cover 6 lateral sliding, riser 7 is owing to produce the skew together with the yarn, so do not influence infrared sensor 8's on riser 7 detection result.

The utility model discloses an infrared sensor 8 detects and has or not big scab on the yarn, if there is great scab, alarm sensor reports to the police, and the electricity connection pilot lamp lights, and machine stop work treats that operating personnel gets rid of the back with the nodule on the yarn, resumes normal machine and normally works simultaneously.

The utility model discloses a concrete embodiment as follows: when the yarn feeder starts to work, the infrared sensors 8 are all in an open state, yarns pass through the first yarn guide holes 2 on the yarn feeding frame and are output through the yarn feeding wheel 4, and finally the yarns are output through the second yarn guide holes 18, the conflict sleeve 6 and the third yarn guide holes 11. Since the small nodules have little influence on the aesthetic knitting of the yarn, and if the small nodules are to be detected, the accuracy of the infrared sensor 8 needs to be high, resulting in an increase in cost.

When a strand of yarn produces skew right or left because of reasons such as tension, because be equipped with first magnetic path 10 and second magnetic path 12 in the bearing groove, first magnet and second magnet repel each other and make and be in the state that does not have direct contact between conflict cover 6 and the guide bar 5, can reduce the frictional force between conflict cover 6 and the guide bar 5, make the frictional force between yarn and the conflict cover 6 be greater than the frictional force between conflict cover 6 and the guide bar 5, yarn and conflict cover 6 can be seen as a whole and take place the skew promptly, and riser 7 is fixed connection again on conflict cover 6, namely the yarn, conflict cover 6, riser 7 offsets together, make the distance between photoelectric sensor on riser 7 and the yarn keep certain distance constantly unchangeable, from not influencing the testing result.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
