To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.

Referring to fig. 1 to 3, the present embodiment provides a flat knitting machine, which includes a frame 1, a driving unit 2, a linkage mechanism 3, a thread passing mechanism 4, a roller mechanism 5, and a thread passing pulley swing mechanism 6. The driving unit 2 is fixedly arranged on the frame 1, and the driving unit can be a speed reducing motor 21 or a servo motor. The roller mechanism includes a first roller 51 and a second roller 52, which are rotatably provided on the frame 1. In this embodiment, the driving unit, the thread passing mechanism, the roller mechanism and the thread passing pulley swing mechanism are fixed by the frame, and when the driving unit drives the roller mechanism to rotate through the linkage mechanism, the roller mechanism can convey yarns for the thread passing pulley swing mechanism, so as to achieve the purpose of actively conveying the yarns. In order to facilitate the smooth routing of the yarns during the conveying process, a plurality of yarn passing mechanisms can be arranged on the rack. Specifically, two wire rods are arranged on one side of the rack, one wire rod can guide the yarn to the flat knitting machine, and the other wire rod can guide the yarn out of the flat knitting machine. The two wire passing rods are cross rods, the cross wire holes are arranged on the cross rods at equal intervals, a plurality of yarns can be separated through the wire passing holes, and the yarns are prevented from being wound when being conveyed.

The roller in this embodiment comprises an outer roller 511, a mandrel 512 and a bearing 513, the mandrel is sleeved inside the outer roller and can extend out of two ends of the outer roller in a penetrating way, and a thread and a nut on one end of the mandrel are fixedly arranged on the frame. The outer cylinder both ends still are provided with the bearing respectively, and the dabber passes through the bearing and rotates with outer cylinder and cup joint for outer cylinder can rotate round the dabber, consequently through link gear, makes drive unit can drive first cylinder and the rolling effect of second cylinder simultaneously, reaches when the initiative is carried the yarn, and two cylinder pivoted angles are the same.

The other end of the roller mechanism in this embodiment is further provided with a triangular positioning frame 514, and the first roller, the second roller and the thread passing mechanism can be fixed on the rack in a triangular position through the triangular positioning frame. The first roller can be locked on the rack through the nut and the thread fit on one end of the mandrel of the first roller, and the other end of the mandrel of the first roller is fixed on the triangular positioning frame through the nut in the same way. In the same way, the second roller and the wire passing mechanism are locked by bolts, so that the other sides of the first roller, the second roller and the wire passing mechanism can be arranged at three top corners of the triangular positioning frame. Through triangle locating rack and cross line mechanism, the trend of guide yarn that can be reasonable, for example the winding of S type for the yarn hugs closely on the cylinder, and through the guide of crossing line mechanism, carries the yarn to crossing in the line pulley swing mechanism simultaneously. And the arrangement of the triangle reduces the occupation of space, and simultaneously, the effects of winding and adjusting the tightness of the yarn can be achieved. The thread passing mechanism which forms triangular positioning with the first roller and the second roller is not the thread passing rod, but is a thread passing plate, the thread passing plate is also provided with thread passing holes which are the same in number and are arranged at equal intervals with the thread passing rod, and the three are formed into the thread passing mechanism, but more thread passing plates or thread passing rods can be arranged for guiding yarns in other embodiments.

The linkage mechanism in the embodiment comprises a main belt wheel 31, a first driven belt wheel 32, a second driven belt wheel 33 and a wedged belt 34, wherein the main belt wheel is arranged on an output shaft of the driving mechanism, the first driven belt wheel is arranged on an outer roller of the first roller, is arranged at one end of the outer roller of the first roller, which is connected with the rack, and is provided with the wedged belt groove; the second driven belt wheel is arranged on the outer roller of the second roller, arranged at one end of the outer roller of the second roller, connected with the frame, and provided with a wedged belt groove, so that the main belt wheel, the first driven belt wheel and the second driven belt wheel are connected through the wedged belt. When the motor is started, the motor output shaft drives the main belt wheel to rotate, and because of the mutual linkage relationship between the wedge belt and the main belt wheel and between the first driven belt wheel and the second driven belt wheel, the main belt wheel can drive the first driven belt wheel and the second driven belt wheel to rotate simultaneously through the wedge belt, so that the outer rollers of the first roller and the second roller are driven to rotate. The driving unit can drive the first roller and the second roller to roll simultaneously, and the rotating angles of the two rollers are the same when the yarn is actively conveyed.

In this embodiment, the first roller and the second roller are respectively provided with a micro-control switch 8, the micro-control switch is electrically connected with the driving unit, and the micro-control switch is used for controlling the driving unit to drive the roller mechanism to rotate when the wire-passing pulley swing mechanism performs a wire feeding action. Specifically, the micro-control switch is mounted on the frame and monitors whether the wire-passing pulley swing mechanism swings or not, and if the wire-passing pulley swing mechanism swings, the micro-control switch controls the driving unit to drive the first roller and the second roller to rotate so as to convey yarns for the wire-passing pulley swing mechanism. The yarn is conveyed actively by matching with the swinging frequency of the yarn passing pulley swinging mechanism, the problem that the yarn is conveyed too much or too little when the yarn is conveyed actively is effectively avoided, and the production efficiency and the quality are improved.

In this embodiment, a roller pressing sleeve is respectively arranged on the machine frame at one side of the first roller and the second roller, and the roller pressing sleeve is used for attaching the guide yarn to the rollers. Specifically, the rotatable installation in the frame of cover is pressed to the cylinder, for example installs in the frame through the bearing, and the central axis that the cover was pressed to the cylinder is parallel to each other with the outer cylinder central axis of cylinder mechanism, and the setting is pressed to the outer cylinder of cover and cylinder mechanism to the cylinder, and the interval between the two is between 0 to 10cm, consequently presses the cover through the cylinder and can roof pressure yarn for more yarns can contact with the outer cylinder of cylinder mechanism, and the cylinder mechanism of being convenient for carries the yarn.

In this embodiment, the outer side of the roller sleeve 7 is provided with a pressing plate 71 protruding outwards, which is a strip plate mounted parallel to the central axis of the roller sleeve on the outer side of the outer roller. Therefore, the pressing sheet can adjust the yarn to pass through the gap between the pressing sheet and the outer roller, thereby adjusting the tightness of the yarn pressed on the roller pressing sleeve. The quantity of preforming in other embodiments can set up a plurality ofly according to the demand, is convenient for adjust the elasticity of yarn, improves the smooth and easy degree of carrying the yarn, improves production efficiency and product quality.

The middle threading pulley swing mechanism 6 is arranged on the frame at one side of the roller mechanism, and the roller mechanism is used for rolling and conveying yarns when the threading pulley swing mechanism swings; the line-passing pulley swing mechanism comprises a line-passing main shaft 61 and a single-double swing pulley frame 62, the single-double swing pulley frame is sleeved on the line-passing main shaft in a swing mode, and the line-passing main shaft is rotatably arranged on the rack.
