Description
Technical field
The present invention relates to a kind of cloth feeding mechanism of eyelet buttonhole sewing machine, the cloth feeding mechanism using engaged transmission between gear simultaneously
The mobile mode of driving tooth shaft drives cloth pushing table movement to carry out work feed operation, avoids in the prior art using the toothed belt transmission longevity
Order short defect.
Background technique
Lockstitch button holder (buttonholing machine) is that a kind of very important equipment, lockstitch button holder are main in garment machinery
Buttonhole for processing in all kinds of dress ornaments is divided into straight buttonholing machine and eyelet buttonhole sewing machine, and is divided to ending and does not finish up two kinds.Wherein
Eyelet buttonhole sewing machine is a kind of industrial sewing machine for being exclusively used in thick material clothes buttonhole in seam lock.So-called " round end " is the buttonhole of webs lock
Front end is rounded.Its main feature is that buttonhole beautiful shape, stitching are uniformly solid.
Lockstitch button holder system is generally made of nine great institutions: feeding mechanism, latch needle mechanism, needle bar mechanism, Beng Liao mechanism, hook shuttle
Mechanism, upper cutter mechanism, slipway mechanism, thread-dividing mechanism.The characteristics of every set mechanism has its own and function have relative independentability,
But they are to be fitted close again at work, mutually coordinated.
Lockstitch button holder is generally using swing shank, double loopers, double forked needle hook lines, two thread chain stitch composite chain type stitching.Lockstitch button holder
Elastic presser foot adapts to the clamping of different fabric thicknesses automatically.Operator can be particularly simple by exchanging two cams come real
Now sew the buttonhole of various shape, size.Upper thread automatic cutting device facilitates operation, and leaves needed for the seam appropriate that begins
Upper thread length, it is ensured that buttonhole sewing.Machine, which soon can first be cut, stitches afterwards and first stitches turn cut afterwards.
China is the big market of current textile machine maximum in the world, garment machinery, and annual textile machine import adds
China's home equipment total value will be more than 8,000,000,000 dollars.Need the support of technical equipment in new developing stage, in addition to itself
Other than being put into more in high salary equipment.Also need quickly to set up large-scale specialized market.Relative to textile machine with multi items,
Based on small lot, garment machinery is then to be more suitable for being sold and being serviced in mass market based on extensive, more batches.
China was also blank out before 15 years, nearly ten years just in this field of lockstitch button holder, especially eyelet buttonhole sewing machine
It is at the early-stage, presently, many kind lockstitch button holders of China's production, and based on the product by copying America and Europe.
Inventor is by the research idea for many years in lockstitch button holder field, it was found that is lacked using the technology of toothed belt transmission
It falls into, especially existing fraternal board 9820 uses rubber synchronous belt feeding, and 500 rpms of feeding speed, synchronous belt often contaminates
Upper machine oil, at most just disconnected using 1 year if work in whole day 24 hours, synchronizing wheel is also often rotten.When replacing this root synchronous belt and needing
Between 3-8 hours, 1000-1500 member of expense.
Summary of the invention
The short technological deficiency of life cycle, the present invention are driven in the prior art between synchronous belt and synchronizing wheel in order to overcome

Afterwards, control clutch disconnects the torque output on the output shaft of motor.
Above controller can also be the power switch for directly controlling motor, once torque is excessive, directly disconnect electronic
The power supply of machine, motor do not work, and also avoiding excessive torque will cause transmission parts (pinion gear, gear wheel and tooth
Axis) destruction.
The mode of above-mentioned motor forward/backward rotation control controller and travel switch can also be realized, the controller
It also connect with the travel switch that tooth shaft engagement tooth ends are arranged in, (or will be touched when the engaging tooth of gear wheel touches
To) travel switch, signal feeds back to controller by travel switch, and controller controls the adjustment that motor carries out positive and negative rotation.
Further, the gear ratio between the pinion gear and the gear wheel is (12-20): (68-82).
The difference of gear ratio can seriously affect the transmitting torque between gear wheel and pinion gear, also will be to a certain extent
Determine the service life of gear wheel and pinion gear, meanwhile, suitable gear ratio can guarantee that the movement speed of tooth shaft is suitble to, because
This selectes this gear ratio, needs to make the creative labor in this field, and ensure that optimal labor productivity.
Further, it is quenched after the gear wheel forms in the fabrication process with the pinion gear through over carburizing.
It is easy always the beneficial effect comprise that avoiding the toothed belt transmission that cloth feeding mechanism uses in the prior art
Change, service life short technological deficiency, and using engaging tooth transmission due to being positive drive, be driven more accurate, substantially prolongs
Service life；Overload protection arrangement is set on motor output shaft and further improves the safety of transmission, ensure that canine tooth
The safety and stability being driven between wheel, pinion gear and tooth shaft, will also prolong the service life to a certain extent；It is distinctive
Transmission ratio between gear wheel and pinion gear ensure that safe transmission also ensures the movement speed of cloth pushing table.
