firstly, the rubber band placing device cannot process the rubber band ring: when a bundle of elastic rings is directly sleeved on the roller, the elastic rings are in a staggered stacking state, so that the hooking of the thread hooking component is not facilitated; if the elastic ring is sleeved on the roller by a single hand, the glove bundling device is actually equivalent to the manual bundling of the stacked gloves.

Secondly, the hook heads of all the thread hooking components need to accurately position the through grooves in the roller so as to ensure that each hook head needs to be hooked to an elastic ring; meanwhile, the wire hooking component is divided into a wire hooking strip and a releasing strip, the structure is complex, the spring pressing sheet bears all stress, metal fatigue is easily caused by the self property of the spring pressing sheet to lose elasticity, and the spring pressing sheet is likely to fall off from the wire hooking strip and the releasing strip; and the gib head of the line hooking strip needs to ensure that the elastic ring is not separated when the line is hooked, and also needs to ensure that the elastic ring cannot be separated when the line is released because excessive resistance is not caused.

Finally, the gloves are pushed by the push plate, so that the finger parts of the gloves are easy to bend, and according to the disclosed scheme, the rib openings of the gloves can only be bundled and are not flexible and comprehensive.

Therefore, the present inventors have further studied this and developed an automatic bundling process of a flat knitting machine, which resulted therefrom.

The rotation plate 311, the rotation table 312 and the rotation gear 3131 can be connected by a main bolt 3133, and the tightness can be adjusted according to actual requirements.

A strip groove 3122 is formed in the middle of the rotary table top 312 for a main bolt 3133 to pass through, and the length of the strip groove 3122 is the translation stroke of the rotary table top 312; when the rotary table 312 is translated under the action of the control rack 3121, when the main bolt 3133 moves to the end of the strip groove 3122, the rotary gear 3131 can no longer drive the control rack 3121 to translate, and at this time, the rotary table 312 can rotate along with the rotary gear 3131.

The rotation control sliding plate 313 controls the rotation plate 311 and the rotating table 312 to integrally translate, that is, the rotation control sliding plate 313 is disposed on the receiving platform 314 and translates relative to the receiving platform 314, and when translating, the rotation plate 311 and the rotating table 312 are driven to move together.
