Description

Automatic rubber band binding device for knitted fabric

Technical Field

The utility model relates to the field of a flat knitting machine, in particular to an automatic knitted fabric rubber band binding device.

Background

The computerized glove knitting machine is one kind of double needle plate latch needle weft knitting machine with triangular device as one set of planar cams, with the needle being capable of entering the channel of the cams, moving the cams to force the needles to make regular elevating motion inside the needle slots of the needle plate and knitting the yarn into knitted fabric through the action of the needle hook and the needle latch. In the ascending process of the knitting needle, the loop gradually withdraws from the needle hook, opens the needle latch, and withdraws from the needle latch to be hung on the needle rod; in the descending process of the knitting needle, the needle hooks hook the newly laid yarn and pull and bend the newly laid yarn into loops, meanwhile, the original loops are separated from the needle hooks, the new loops pass through the old loops and are connected with the old loops in series, and a plurality of loops formed by knitting are connected with each other to form the knitted fabric.

The knitted fabric falls down after being formed between the double needle plates, and the knitted fabric can be neatly moved to a platform or a conveyor belt at the outer side of the computerized flat knitting machine by an automatic finishing device such as disclosed in CN202111320479.3, and the neatly stacked knitted fabric is automatically bound by an automatic binding device.

The automatic arranging device and the bundling device are only developed in the field in nearly two years, but are still imperfect, wherein Zhejiang Baixiang technology and technology corporation discloses an automatic glove bundling machine in a section of 202122521567.1, and the automatic glove bundling machine comprises an elastic band receiving and bundling device, an elastic band placing device and a pushing sleeve device, but the scheme has the following defects:

firstly, the rubber band placing device cannot realize the treatment of the bundled rubber band rings: when a bundle of elastic bands is sleeved on a single roller, the elastic bands are in a staggered and stacked state, which is not beneficial to hooking of the hooking component; if the rubber band ring is arranged manually and then sleeved on the roller, the manual bundling of the stacked gloves is equivalent in fact, and the production efficiency cannot be improved.

Secondly, the hook heads of all the hook wire components in the rubber band connection and bundling device need to accurately position the radial through grooves on the roller, and the radial through grooves still need to stay at the same position each time after rotating due to the rotation of the roller, so that each hook head needs to be hooked to the rubber band ring; meanwhile, the hooking component is divided into a hooking strip and a releasing strip, the structure is complex, the spring pressing piece bears all stress, and the self property of the spring pressing piece causes metal fatigue to lose elasticity easily, and the spring pressing piece is likely to fall off from the hooking strip and the releasing strip; the hook head of the hooking line is required to ensure that the elastic ring is not separated when hooking the line, and the elastic ring cannot be separated when releasing the line due to excessive resistance.

Finally, in the glove pushing device, the glove is pushed by the push plate, bending of the finger part of the glove is easy to be caused, and according to the scheme disclosed by the glove pushing device, only one end of the glove can be bundled.

Therefore, the inventor further research the device and develops an automatic knitted fabric rubber band binding device, and the scheme is generated.
