Description

The feeding structure of high cast industrial sewing machine

Technical field

The utility model is relevant for a kind of feeding structure of high cast industrial sewing machine, especially refer to a kind of directly industrial sewing machine of long vertical tube of tool that is applied to, and utilize this Sewing machines for dark cartridge type object when carrying out sewing, object can be sheathed on the vertical tube, and provide its stable providing and delivering to close, and then reach the feeding structure of synchronous passing object with the needle bar pin.

Background technology

Industrial sewing machine of a great variety, also divide tool different sewing usefulness, except the most common flatcar in order to sewing plane cloth or cladding, other has a kind of boots footwear that are used to make, the height of bag or the special use of a simple shape object vertical tube type, its general common name senior executive type Sewing machines, it mainly improves the head and the vertical tube of Sewing machines, and be a predetermined altitude with board, when the aforementioned dark cartridge type object of sewing, object can be inserted in this upright vertical tube, and the user is provided sewing easily, and in the feeding structure (seeing also shown in Figure 1) of public senior executive's type Sewing machines, it mainly is to establish a shuttle axle B in the main vertical tube A, the shuttle C that provides bottom line to be installed with is provided on shuttle axle B top, there is a helical gear D its bottom then device, and the gear that makes this helical gear D be subjected to main shaft F establishing in addition (figure does not show) drives, and shuttle axle B is rotated and cooperates needle bar (figure does not show) pin to send the sewing object; Again, the side of vertical tube A is provided with one and send tooth plate G, send tooth plate C top to be provided with a work feed tooth H (promptly being commonly called as the dog tooth), the tooth wrist I that send of its top, end and main shaft F articulates, when main shaft F turns by sending tooth wrist I to produce the eccentric motion of similar cam, and then to promote to send tooth plate G be that the center produces beat with its binding end, making to be located at send the work feed tooth H on the anti-G of tooth top to be the upper and lower displacement of amplitude of oscillation shape, utilize afore-mentioned characteristics, when shuttle axle B cooperated the needle bar pin to send the sewing object, this work feed tooth H got the performance that pushes object in good time and reach step feeding; But, when using, reality finds to have following shortcoming with regard to the applicant: one, this work feed tooth H adopts the upper and lower displacement of amplitude of oscillation shape, in fact only move to the moment of top dead-centre at work feed tooth H, and during to the object contact application of force, beginning has pair object to implement step feeding, so the sewing object surface takes place and tears after by work feed tooth H or wear and tear in regular meeting, and this work feed tooth H is not that the feeding style of following during with perseverance object to pass carries out, and makes and is making object, during especially more thick and heavy object, regular meeting is not enough or discontinuous because of the strength that pushes, cause and make object generation wrinkle Zhe, promptly need this moment pull out with auxiliary object is drawn of manpower, and from increasing the puzzlement of operation; When in addition pulling out object with the manpower auxiliary traction, also regular meeting lack experience because of personnel or the application of force improper, make that to be pulled object impaired or inconsistent because of pulling out speed, and then when the needle bar sewing, cause the generation needle gage and differ and influence the quality of making object.They are two years old, because the height of general vertical tube A is about about 45 to 55 centimeters, sending the bottom of tooth plate G to be hubbed on again send on the tooth wrist I, and with its binding end is that the center produces beat, work feed tooth H is located at the top of sending tooth plate G again, therefore this send the eccentric motion of tooth wrist I need with minimum amplitude, just can keep work feed tooth H and in predetermined stroke, do the upper and lower displacement of amplitude of oscillation shape, so must be quite except that the precision of making therebetween and assembling accurately, also often to adjust its gap of vacillating, so just can keep the best feeding usefulness of work feed tooth H; In addition, owing to send tooth wrist I inside by members such as cam and Bearing groups, after using a period of time, it can produce abrasion, therefore can cause this work feed tooth H can't push object accurately, the consume of cam or Bearing group simultaneously, having some setbacks in the time of also can allowing work feed tooth H produce vibration and feeding; And then influence the quality of sewing object.
