Lockstitch button holder in above patent document needs artificial moving cloth after sewing a keyhole every time, can not realize certainly
It is dynamic continuously to sew multiple keyholes, result in the need for multiple bearing, low efficiency.
Summary of the invention
The object of the present invention is to provide a kind of auxiliary drive gears of lockstitch button holder, its advantage is that can pass automatically to cloth
It is dynamic, convenient for carrying out keyhole again, to improve keyhole efficiency.
Above-mentioned technical purpose of the invention has the technical scheme that
A kind of auxiliary drive of lockstitch button holder is arranged on keyhole platform, is provided with lockstitch button holder ontology above keyhole platform, locks
Setting pedestal below eye platform, keyhole Platform center region offers the through-hole for keyhole, the auxiliary drive packet
The active drive mechanism being arranged in pedestal is included, and is arranged on lockstitch button holder ontology and is used cooperatively down with active drive mechanism
Press mechanism；
The two sides that the keyhole platform is located at through-hole respectively offer a relief hole being parallel to each other, and the active drive mechanism includes
Level is folded in two rotating rollers in pedestal, and two rotating rollers are parallel to each other and are located at the lower section of corresponding relief hole；In pedestal
It is additionally provided with and two rotating rollers is driven to move up the upper component for making rotating roller protrusion keyhole platform；Drive two is additionally provided in pedestal
The first driving mechanism that a rotating roller rotates in same direction；
The press mechanism includes two driven vollers being parallel to each other above keyhole platform with rotating roller being arranged in, and setting exists
Two driven vollers of driving move down two the second driving mechanisms for being pressed against rotating roller and driven voller mutually in lockstitch button holder ontology.
Through the above technical solutions, when this body running of lockstitch button holder carries out keyhole work to the cloth for being placed on keyhole platform
Afterwards, upper component operation drives two rotating rollers to move up, and two rotating rollers is made to protrude from the upper surface of keyhole platform, so
Afterwards the first driving mechanism work drive two rotating rollers rotate in same direction, and at this time the second driving mechanism will drive two driven vollers from
It is moved down above keyhole platform, and clamps rotating roller and driven voller to cloth, by the first driving mechanism to two
The control of rotating roller, to drive cloth mobile to a direction, when to needing keyhole to work, the first driving mechanism stops
Work, upper component drive two rotating roller returns, consequently facilitating staff carries out keyhole to cloth again.Staff without
Need to be after the work of each keyhole, then the position of cloth is manually adjusted, then in the contraposition for carrying out keyhole, pass through active drive mechanism
With the mutual cooperation of press mechanism, cloth can be automatically adjusted in the movement of keyhole platform, carries out keyhole in manual fine-tuning, thus
Improve the keyhole efficiency of staff.
The present invention is further arranged to: the both ends of each rotating roller are respectively vertically arranged with a limit slide bar, and limit is slided
The upper end of bar is fixedly connected with keyhole platform, and limit slide bar is from top to bottom successively connected with the first limit film and the second limit film,
The rotating roller bottom is provided with the attachment base of a support rotating roller, and attachment base and rotating roller are rotatablely connected, and limit slide bar is upper
The first slide plate of one with limit slide bar sliding connection, the first slide plate side are provided between the first limit film and the second limit film
It is fixedly connected with attachment base.
Through the above technical solutions, attachment base plays the role of support to rotating roller, and rotation is not interfered with
Roller is freely rotated, and the first slide plate slides on limit slide bar, thus define glide direction of the rotating roller in pedestal, the

Line is connected with drive block 324, and above-mentioned gag lever post 322 is threaded through drive block 324, and slides and connect with drive block 324.Drive block
324 side is connected with the drive rod 325 of L-type, and above-mentioned driven voller 31 is connected horizontally on the end of drive rod 325, and with driving
Bar 325 is rotatablely connected, and the two sides of shell 141 respectively offer the sliding slot 142 of 325 vertical sliding of a receiving drive rod.
When staff carries out keyhole work to cloth, two rotating rollers 21 are made to rotate by the driving of upper component 22
Roller 21 protrudes from the upper surface of keyhole platform 13.Two third driving motors 323 start at this time, drive screw rod 321 to rotate, pass through
Screw rod 321 is threadedly engaged with drive block 324, and makes drive block 324 under the limitation of gag lever post 322, drives drive rod 325 perpendicular
Histogram makes driven voller 31 mutually recline to bottom offset with corresponding rotating roller 21, and cloth is folded in driven voller to movement
Between 31 and rotating roller 21.Start the second driving motor 232 at this time, by the transmission of transmission belt 234, drives two rotating rollers 21
It rotates in same direction, and the frictional force between cloth and rotating roller 21 is increased by the pressing of driven voller 31, so that cloth is in keyhole
It is displaced on platform 13, when cloth is displaced to the position for needing keyhole, the second driving motor 232 stops working, upper component 22
Two rotating rollers 21 are driven to be returned in pedestal 12, and third driving motor 323 rotates backward, and drives two driven vollers 31 upward
Mobile, staff, which can be finely adjusted cloth, at this time carries out keyhole effect again and passes through active driver after the completion of keyhole
The cooperation of structure 2 and press mechanism 3 again automatically moves cloth, to reduce artificial frequent operation, not only saves
The physical demands for having saved staff also improves keyhole efficiency.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
