Detailed description of the invention

Understand more specifically for having technology contents of the present invention, feature and effect, now in conjunction with illustrated embodiment, details are as follows:

Please coordinate shown in Fig. 1,2,3, a support 20 is provided with below the needle plate 10 of this Sewing machines, a cloth feeding mechanism 30 is separately provided with at this support 20, this needle plate 10 palisade dead slot structure place is provided with a cloth conveying teeth 31 promoted for this cloth feeding mechanism 30, be be fixed on a rectangle horizontally disposed toothholder 32 end face bottom this cloth conveying teeth 31, and these toothholder 32 both ends system is located in a work feed connection rod set 33, and drives for it, and the structure of this work feed connection rod set 33 is a known structure, separately do not repeat at this; And this cloth conveying teeth 31 drive cloth forward the direction that moves horizontally backward be X-direction, vertically the direction of the adjustable height of this X-direction is Z-direction, and horizontal direction is Y direction to the left or to the right, is the direction of the improper horizontal-shift of cloth conveying teeth;

And feature of the present invention is this guiding structural ties up to this cloth feeding mechanism 30 with this support 20 relative position and separately have the guiding device 40 be located on support 20 and the structure coordinated, along X-direction displacement there is the relative displacement nargin of Z-direction with the cloth conveying teeth 31 reaching really this cloth feeding mechanism 30 of guiding, and do not produce the object of Y direction skew improperly;

Wherein, toothholder 32 below this cloth conveying teeth 31 is relative with this guiding device 40 to be provided with two and to lead portion, namely at the lower center position place of this toothholder 32, namely locate immediately below cloth conveying teeth 31, be provided with a groove-like extended along aforementioned X-direction first leads portion 320, first to lead the recess in portion 320 downward for this, and this first height of the degree of depth slightly larger than this cloth conveying teeth 31 rise and fall Z-direction displacement of leading portion 320;

This support 20 has an end wall 21 extended along Z-direction, this end wall 21 is separately provided with a locking member portion 22 relative to this guiding device 40 position, a locating hole 210 is provided with by this end wall 21 direction vertical, and this locking member portion 22 central position is provided with an adjusting hole 220 along Z-direction, this locating hole 210 is in the form of vertical connection with this adjusting hole 220 and locating hole 210 inner radius has internal thread, is arranged at therebetween to coordinate the relative component of this guiding device 40;

This guiding device 40 has an adjustment part 41 and positioning piece 42, wherein, this adjustment part 41 has a shaft-like adjustment part 411, to be set in this adjusting hole 220, and the bottom that this adjustment part 411 exposes to this adjusting hole 220 is separately provided with an adjustment end 412 that can drive for a word bottle opener, the another end of this adjustment part 411 is then stretched out this adjusting hole 220 and is provided with one and discoidly surely leads portion 413, surely lead portion 413 and correspond to eccentric position place on end face that this toothholder 32 first leads portion 320 at this and be separately convexly equipped with second of a column and lead portion 414, by rotating this adjustment part 411 to change this second position of leading place, portion 414, it is made to lead can adjust to some extent because of the machine error of this work feed connection rod set 33 coordinating of portion 320 with first, to be adjusted to accurate location, this keeper 42 can be coordinated to be forced to this adjustment part 41, dynamic to make this adjustment part 41 remain on to maintain static.

And this keeper 42 external diameter has external screw thread, screw lock is in this locating hole 210, and this keeper 42 expose to this locating hole 210 end be set as the hexagonal drive end 420 of indent for hex tool embed rotate drive, and this keeper 42 extend the end supporting this adjustment part 41 in this adjusting hole 220 be one cone shape support end 421, after adjusting to make this adjustment part 41, this adjustment part 41 was made to keep the object of not rotating through pushing against of end 421 should be supported.

From said structure, the present invention has following effect:

Certain guiding: this cloth conveying teeth 31 and toothholder 32 coordinate the guiding of this guiding device 40 to remain on best path to move really, please coordinate shown in Fig. 4 and 5, second of this adjustment part 41 leads portion 414, and no matter this cloth conveying teeth 31 is in any position of work feed stroke, all first can be coordinated to lead the certain guiding in portion 320, the improper Y direction offset motion of unlikely generation, remains on best state to make the quality of sewing.

Adjustable operability is high: the configuration of the mutual eccentric position in portion 414 is led in the adjustment part 411 and second by this guiding device 40 adjustment part 41, therefore when rotating this adjustment part 411, this can be made second to lead portion 414 and move larger scope, and reach the object of height adjustment applicability and handled easily.

Structure simplifies: the component of the structure of cooperation guiding device 40 and this guiding device 40 itself and structure, it is not the structure of a complexity, only coordinate the setting of keeper 42 can reach the position of guiding and adjustment guiding by an adjustment part 41, overall simplification is easy to operate.

Separately also can be as shown in Figure 6, this first is led portion 320 ' and is located at bottom the toothholder 32 of cloth conveying teeth 31, and this adjustment part 41 ' axle center of this guiding device 40 ' is arranged along X-direction, this keeper 42 ' is then arranged in the Z-axis direction, and the locating hole 210 ' of this support 20 and the position of adjusting hole 220 ', also coordinate reversing of position, still can reach aforesaid various functions.

Again can be as shown in Figure 7, this toothholder 32 is separately provided with one along the locating hole 321 in X-direction, and be communicated with this locating hole 321 ending vertical direction and be provided with an adjusting hole 322, this guiding device 40 " there is an adjustment part 41 " and positioning piece 42 ", this keeper 42 " spiral shell is located in this locating hole 321, this adjustment part 41 " then screw lock in this adjusting hole 322, and this adjustment part 41 " with keeper 42 " structure all identical with aforesaid example structure, and at this adjustment part 41 " one end stretch be provided with second of an eccentric position and lead portion 414 ", and the end wall 21 of this support 20 second leads portion 414 relative to this " place is separately provided with first of a groove and leads portion 211, this first is led portion 211 and to extend and recess second leads portion 414 towards this along aforementioned X-direction ", and this first Z-direction height of degree of depth system slightly larger than this cloth conveying teeth 31 rise and fall displacement of leading portion 211, also the function of previous embodiment is reached equally.

Another aforementioned as shown in Figure 8, of the present invention first leads second of portion 310 or this guiding device leads portion and can be directly arranged on cloth conveying teeth 31, also aforementioned every function can be reached, as shown in this legend, leading portion 310 by first is directly arranged on this cloth conveying teeth 31, also aforesaid second portion of leading can be located at this cloth conveying teeth.
