Description

The yarn cutting device of seamless underwear machine

Technical field

The utility model belongs to the Knitting Machinery field, more specifically, relates to seamless underwear machine, particularly the yarn cutting device of seamless underwear machine.

Background technology

Seamless underwear is the product that welcome by consumer, particularly female consumer, and correspondingly, the exploitation of seamless underwear machine has also obtained very big progress.Seamless underwear belongs to the one-sided composition fabric, and institutional frameworks such as jacquard weave, line transfer, plaiting are arranged mostly.Traditional circular knitting machine and homemade simple and easy seamless underwear machine all do not have automatic broken yarn device and refuse yarn recovery system, in the braiding process, can't handle the flotation line of jacquard weave formation, the surplus line that shuttle changing forms, cause flotation line, surplus line to twine mutually along with the rotation of machine, strain, had a strong impact on fabric quality.For this reason, after weaving textile is finished, must cut off grey cloth by closed-down manual, have a strong impact on production efficiency, and production cost is increased; In the braiding process, as can not in time shut down when fabric defects such as dropped stitch, floricome occurring, must after whole weaving textile finished output, manually wipe out defect ware, cause product defect rate height, waste of raw materials.

Summary of the invention

The utility model will solve flotation line, the surplus line problem that influences to fabric, and a kind of yarn cutting device of automatic seamless underwear machine is provided.

The utility model has adopted following technical scheme: the yarn cutting device of seamless underwear machine is characterized in that: it comprises that a disk scissors and several go up scissors, the rotation of disk scissors random device, and last scissors is provided with perpendicular to the direction of motion of disk scissors; All have one group of cylinder, piston on each on the scissors, by the upward action of scissors of piston control.

As further technical scheme, the place ahead of scissors is provided with one group of clip on each, at broken yarn front clamp yarn; Described clip is made up of the thread guides of two interception yarns, and thread guide is controlled by one group of cylinder, piston respectively that it is opened, closure.

The scissors place is equipped with an inlet scoop on each, is connected by pipeline with air draught equipment, forms negative pressure.The rear end of air draught pipeline is provided with a trash receptacle, in the bucket filter screen is housed.

Mutual shearing force when the utility model utilizes the disk scissors with respect to the rotation of last scissors can be cut off yarn; Be provided with a plurality of scissors of going up, just can cut surplus line more in time, as the quantity of establishing scissors is that n is individual, then in 1/n circumference, just can cut yarn at most; Clamp behind the yarn with clip and to shear again, make shearing rapider, and can not have influence on other parts of fabric; The setting of inlet scoop, air draught pipeline makes that the refuse yarn of cutting is removed immediately, the instant recovery.

Adopt the utility model to enhance productivity, reduce defect ware, improve the quality of products, reduce the cost waste.Automatically cut off yarn after a weaving textile is finished, the output fabric need not to shut down and just can realize single-piece braiding, single-piece output.When problems such as broken needle, floricome occur causes the grey cloth flaw, can shut down reparation at any time, and can in time cut off yarn, with the substandard products output that has occurred.

The specific embodiment

With reference to accompanying drawing 1, accompanying drawing 2, the utility model comprises 8 respectively by the last scissors of one group of cylinder, piston control and 1,8 scissors inlet scoops 8 of disk scissors of 1 random device rotation.Disk scissors 1 is provided with last scissors is vertical, and last scissors is installed on the scissors inlet scoop 8, and the place ahead of scissors is provided with the clip of one group of clamping yarn on every group.Disk scissors 1, scissors inlet scoop 8, clip all place on the scissors dish seat 2.

Shown in accompanying drawing 6-8, last scissors is installed on the scissors inlet scoop 8, and scissors comprises scissors seat 9, the scissors cutter head 12 of going up shear shank 11, being connected with last shear shank on every group.Be provided with scissors piston 10 between the endoporus of the upper end of last shear shank 11 and last scissors seat 9, last scissors piston 10 and last shear shank 11 can use air pressure that last scissors is carried out height and regulate by being threaded; Last shear shank is provided with spacer ring, upward the scissors stage clip plays reset response; Last scissors seat 9 is provided with a slotted hole, and last scissors primary screw 17 places in the hole and with last shear shank 11 and is connected, and plays the positioning and guiding effect; Be connected with eccentric shaft 16 on the scissors inlet scoop, an other end of eccentric shaft places in the scissors seat, can regulate the position of scissors.

Shown in accompanying drawing 3-5, the thread guide frame 6 that every group of clip include the column 7 that is used to install the location, be connected with column by screw, block line pressure plate 3, block line base plate 5 and by straight pin with block the line base plate and block the thread guide 4 that the line pressure plate is connected the location.Be provided with piston 13 in the thread guide frame, piston 13 move downward under the promotion of air pressure thread guide is opened hook yarn after, air pressure is released, and connects the back-moving spring 14 that extension spring post 15 1 ends connect thread guide 4 by an end thread guide is return original position, realizes the clamping of clip to yarn.
