industries such as family is spun, clothes, case and bag, handbag, shoes and hats, mainly be applicable to cotton, chemical fibre, silk flower bud, etc. the single or multiple lift of fabric and leather, by quilting, sew with long stitches the clock formula, carry out quilting and the embroidery of various patterns.The roller transmission mechanism of embroidering machine mainly comprises and is arranged on the embroidering machine frame that support the saddletree of whole roller transmission mechanism and by its axially movable X axis pendulous device and X axis track-type facilities, comprise that being arranged on cloth roll on saddletree send the roller group and send drive motors by the volume of its driving, comprise pan feeding roller group and by the pan feeding drive unit of its driving, comprise tensioning roller group and by tensioning drive motors and the transmission device of its driving, comprise discharging roller group and by the discharging drive motors of its driving, wherein cloth roll send the roller group to comprise three horizontal cloth spool rollers that the separation of upper, middle and lower vertical direction is arranged, every cloth spool roller send drive motors to drive by a volume, pan feeding roller group only has a roller, tensioning roller group comprises that two components are placed in three roller roller groups of embroidery frame front and back, two rollers of the conveying in same level and the tensioning rollers in these two conveying roller tops before and after described three roller roller groups comprise, they are the product word and arrange, wherein tensioning roller two ends are provided with lowering or hoisting gear, described discharging roller group comprises discharging roller and the clamping roller in top in below, axial connecting line between them tilts to the discharging opening direction, the two ends that wherein clamp roller have elevation and subsidence regulating device, the embroidering machine feeding manner of this structure is: during single or multiple lift cloth process pan feeding roller group, be superimposed together, then be transported to tensioning roller group, cloth through the front and back of two group of three roller roller group carry the bottom surface of roller and tensioning roller above, be that the tensioning roller up carries be tensioning state, between two group of three roller roller group, be to sew with long stitches to embroider zone, cloth is transported to discharging roller group after sewing with long stitches embroidery, wherein discharging roller and clamping roller apply chucking power to cloth cloth are exported.The embroidering machine of this structure is if the words that many clothes are sew with long stitches to embroidery side by side together simultaneously, its structure is simply machine to be spelled to length, each cloth is independent input, between each cloth, be unconnected, be equivalent to the effect that many single machine amalgamation is used simultaneously, each cloth both sides is all left and is embroidered the place that pin can't arrive, so just reduced the embroidery area, wasted cloth, between each cloth of possibility, the uneven easily generation of transporting velocity is asynchronous simultaneously, and cloth is under a roller guiding of pan feeding roller group, the direct ninety degree turn break-in of cloth is without compression, easily cause cloth fold impact embroidery quality, so optimal situation is all cloth can be connected to conveying side by side, the buffering turning also compresses, synchronous embroidery, both can greatly increase work efficiency and increase cloth embroidery area, reduce the cloth waste, can make again transporting velocity balance between each cloth, easily synchronous embroidery, cloth is difficult for producing fold, improves the embroidery quality, realize this ideal situation, must solve following problem by emphasis technically: because each roller lengthens by necessary side by side for many clothes, and after the roller lengthening, its rigidity just needs to strengthen, increase supporting if strengthen the roller rigid type bearing position of rigidity at needs, this supporting affects again passing through smoothly of cloth, this is a technical problem, but in prior art, comprise that same many clothes embroidery separately arranged side by side of being about to just is used for increasing work efficiency both at home and abroad, do not solve the above-mentioned method that cloth waste and embroidery quality problems occur, more do not solve the technical scheme of this technical problem, so also do not occur thering are many connection embroidering machine roller transmission mechanisms that many clothes connect the embroidery function side by side at present.
