Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of covering yarn spinning, in particular to a covering yarn spinning device. BACKGROUND

[0002] Covering yarn is a kind of yarn with composite structure formed by two or more fiber bundles or yarns spirally wound along the length direction through the application of tension and twisting. During the formation of covering yarn, the yarn is unwound and rubbed with guide hooks, tensioners, hollow spindles and the like multiple times, the surface fluff fluctuates, and it has strong static electricity. In order to prevent the yarn from being frequently broken during weaving, affecting the weaving efficiency and the quality of finished products, the yarn needs to be oiled, aiming to eliminate static electricity and lay down fluff.

[0044] The rear end of the first support frame 21 is fixedly connected to the front surface of the mounting plate 24, the rear end of the second support frame 22 is fixedly connected to the front surface of the mounting plate 24, the oil passing groove 25 is installed on the front surface of the mounting plate 24, the limiting roller 26 is located above the oil passing groove 25, the guide roller 23 is located in front of the oil passing groove 25, the pressing block 15 is located directly above the guide roller 23, the end of the push cylinder 20 away from the swing frame 19 is rotatably connected to the front surface of the mounting plate 24, and the cylinder shaft of the locking cylinder 14 penetrates the inner top wall of the sliding groove 12 and is fixedly connected with the sliding block 13;

[0045] By using the locking cylinder 14 to push the slider 13 to slide within the groove 12, the slider 13 causes the pressure block 15 to move downwards and contact the guide roller 23, thus clamping and fixing the yarn and preventing it from falling off. By pushing the cylinder 20 to push the swing frame 19, the swing frame 19 swings through the first support frame 21 and drives the limiting roller 26. At this time, the limiting roller 26 moves upwards, which can make way for the yarn. When the electric push-pull rod 17 provides pulling force, the first connecting rod 16 moves towards the second connecting rod 18. The first connecting rod 16 drives the mounting base 11, which in turn drives the guide roller 23 and the pressure block 15 to move upwards. Thus, the yarn can move upwards along with the guide roller 23 and the pressure block 15. Since the limiting roller 26 has made way, the yarn is completely separated from the oil wheel in the oil trough 25, preventing the yarn from being over-soaked in oil and facilitating the yarn splicing work for the staff.

[0049] The guide groove 37 can guide the yarn and limit its position. During operation, the yarn exerts a slight pressure on the guide wheel 33. Through the cooperation of the sliding seat 32 and the pressure rod 36, the slight pressure can be transmitted to the pressure sensor 35. When the pressure sensor 35 detects pressure, it indicates that the yarn is in normal condition. When the pressure sensor 35 does not detect pressure, it indicates that the yarn is broken.
