The needle swinging mechanism of the pocket-hole sewing machine comprises a needle rod with a sewing needle, a connecting support is connected in the middle of the needle rod fixedly, and a transmission rod is connected on a support of a connecting rod and connected with a driving mechanism capable of driving the transmission rod to swing back and forth. The needle swinging mechanism of the pocket-hole sewing machine has the advantages of capability of meeting the requirement of special sewing and high working stability and the like.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to the needle vibrating mechanism of a kind of bag-opening machine, particularly a kind of bag-opening machine.
Background technology
Sewing machine for covering chain stitch mainly is with a sewing thread, on sewing, forms a kind of stitching, the machine that makes one or more layers sewing interweave or unite by a seam.Usually be divided into thin material and two kinds of purposes of thick material, sewing machine for covering chain stitch can be made goods such as fabric such as cotton, fiber crops, silk, hair, artificial fibre and leather, plastics, paper, and it is knitting that thin material generally is used for, underwear; Shirt, uniform etc., thick material generally is used for all kinds of sportswears, jean; Fashionable dress, overcoat, shoes and hats, skin is young; Case and bag etc., flat seam machine is the most basic car type at sewing device, in making, is the simplest stitching; The stitching neat appearance, the stitching that sew are even, and smooth firmly sewing velocity is fast, easy and simple to handle, and use is easily understood.The highest sewing velocity is 4000-5000rpm.
The shank of in the past opening bag flat seam machine automatically can only move back and forth up and down, and when needs reach special making and require, need make micro-reciprocally swinging about shank.Obviously, the existing bag flat seam machine of opening can't reach this purpose.
Summary of the invention
The purpose of the utility model is the problems referred to above that exist to prior art, and a kind of needle vibrating mechanism of simple in structure, bag-opening machine that job stability is high is provided.
The purpose of the utility model can realize through following technical proposal: a kind of needle vibrating mechanism of bag-opening machine; Comprise shank with suture needle; It is characterized in that; Described shank middle part is fixed with the connection support, is connected with drive link on the connecting rod rack, and the driving mechanism that drive link and can drive its reciprocally swinging links.
In the drive mechanism drive link reciprocally swinging process, because drive link is connected with shank through connecting support.Therefore, actuator finally drives the shank reciprocally swinging, thereby reaches the requirement that bag-opening machine is made.
In the needle vibrating mechanism of above-mentioned bag-opening machine; Described driving mechanism comprises motor, eccentric wheel and connecting rod; Eccentric wheel is connected in the rotating shaft of motor and eccentric wheel and machine shaft is eccentric is provided with; One end of connecting rod has trepanning and trepanning is placed on the eccentric wheel, and the other end of connecting rod is hinged on the drive link.
Pass through eccentric wheel drivening rod reciprocally swinging in the motor rotation process, because connecting rod is to be hinged on the drive link, so finally drive the drive link reciprocally swinging.
In the needle vibrating mechanism of above-mentioned bag-opening machine; Be fixed with contiguous block on the described drive link; Has the connecting hole that is complementary with drive link on the contiguous block; Said contiguous block upper edge connecting hole axially has the breach that runs through together, and the indentation, there of said contiguous block has the securing member that can make indentation, there closed, and the above-mentioned connecting rod other end is hinged on the contiguous block.
The structure of contiguous block makes it to be connected in firmly on the drive link, and connecting rod can easily be hinged on the drive link again simultaneously.
In the needle vibrating mechanism of above-mentioned bag-opening machine, said drive link end has the connecting hole that is " ten " word shape, and said connection stent side portion has the plush copper that is complementary with connecting hole, on a latch is connected in drive link simultaneously and is connected support.
Such structure make drive link be connected support and can firmly connect, under the latch effect, can also prevent drive link simultaneously and be connected that support becomes flexible or disengaging.
In the needle vibrating mechanism of above-mentioned bag-opening machine, have two tubular connecting portions on the said connection support: connecting portion one and connecting portion two, said connecting portion one and connecting portion two concentric settings, above-mentioned shank links to each other with connecting portion two with connecting portion one simultaneously.
In connecting portion one and connecting portion two effects down, shank and be connected the connection area increase of support, the connection that both more can be firm.
Compared with prior art, the needle vibrating mechanism of this bag-opening machine is owing to drive through eccentric mechanism, and the effect through drive link under the connecting rod effect makes that shank can reciprocally swinging, thereby satisfies the requirement of making of bag-opening machine.
Simultaneously, drive link makes both be connected firmly with the connected mode that is connected support, can not cause drive link because of long-time swing and be connected support and become flexible, and therefore, its job stability is also than higher.
