Abstract

A needle hole and a feeding tooth groove are formed in the needle plate, a partition plate is fixedly arranged at the position of a center seam of an upper piece movement track on the needle plate, and the partition plate is arranged at the front end of the needle hole and makes contact with an upper piece earlier than the needle hole. According to the utility model, the metal partition plate is welded at the middle seam position of the upper piece movement track on the needle plate, so that the width of a butt seam is ensured to be within a process requirement range, when the butt seam process operation is carried out, the metal partition plate firstly separates the two upper pieces at the front end of the needle falling position, and then sewing is carried out, so that the phenomenon that the upper pieces are overlapped is avoided, and compared with the prior art, the production efficiency is improved. When the overlap-preventing needle plate of the opposite sewing machine is used for upper piece sewing operation, the working efficiency is improved, and the rework rate is reduced.

Description

TECHNICAL FIELD

[0001] The utility model belongs to shoemaking auxiliary equipment technical field, concretely relates to a kind of needle plate for preventing overlap of overlock machine. BACKGROUND

[0002] When overlock sewing is carried out to shoe upper piece component, since upper piece component has camber, two pieces of upper piece are prone to overlap phenomenon when overlock sewing, affect product quality, need rework processing, affect efficiency. SUMMARY

[0003] In order to prevent overlap phenomenon at the joint of two pieces of upper piece, the utility model provides a curve sewing machine with edge wrapping.

[0004] The utility model discloses a kind of needle plate for preventing overlap of overlock machine, needle hole and feeding tooth slot are provided on needle plate, the middle seam position of upper piece movement track on needle plate is fixedly provided with baffle, and baffle is in needle hole front end, more needle hole first contact upper piece.

[0005] Baffle length is 0.5-1.5cm, height is 0.1-0.5cm.

[0006] Baffle is welded and fixed on needle plate.

[0007] Feeding tooth slot includes two continuous feeding tooth slots and two intermittent feeding tooth slots, needle hole is located in intermittent feeding tooth slot middle, baffle is clamped on adjacent two intermittent feeding tooth slots.

[0008] Compared with prior art, by observing needle position and upper piece position when machine runs, the utility model welds a metal baffle at the middle seam position of upper piece movement track on needle plate, ensure that the gap width of overlock is within the range of process requirement, when overlock process operation is carried out, metal baffle separates two pieces of upper piece first before needle drop position front end, then carries out sewing, so that upper piece overlap phenomenon does not appear. BRIEF DESCRIPTION OF DRAWINGS

[0009] Fig. 1 It is front view of the utility model.

[0010] Fig. 2 It is top view of the utility model.

[0011] Fig. 3 It is left view of the utility model. DETAILED DESCRIPTION

[0012] The utility model is further illustrated below in combination with the drawings and specific embodiments. It should be understood that these embodiments are only used for illustrating the utility model and are not used for limiting the scope of the utility model. After reading the content of the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the utility model.

[0013] As shown in the figure, a kind of anti-overlapping needle plate for matching machine, needle hole 3, needle plate fixed screw hole 4 and feeding tooth slot 5 are arranged on needle plate 2, and the middle seam position of the upper piece movement track of needle plate 2 is fixedly provided with baffle 1, and baffle 1 is in front of needle hole 3, and baffle 1 contacts the upper piece earlier than needle hole 3. Figs. 1-3

[0014] Further, baffle 1 is metal material, length is 0.5-1.5cm, preferably 1cm, height is 0.1-0.5cm, preferably 0.3cm.

[0015] Further, baffle 1 is welded and fixed on needle plate 2.

[0016] More further, feeding tooth slot 5 includes two continuous feeding tooth slots 51 and two intermittent feeding tooth slots 52, needle hole 3 is located in the middle of intermittent feeding tooth slot 52, and baffle 1 is clamped in adjacent two intermittent feeding tooth slots by two supporting legs.

[0017] Screw passes through needle plate fixed screw hole 4 to fix needle plate 2 below needle foot of needle car, and needle corresponds needle hole 3 on needle plate 2, and baffle 1 separates two upper pieces needing matching, and the upper pieces are sewn in needle hole 3 position.

[0018] By observing needle foot position and upper piece position when matching machine is operated, the utility model welds a metal baffle 1 in the middle seam position of the upper piece movement track on needle plate, guarantees that the seam width of matching is within the range of process requirement, and when carrying out matching process operation, metal baffle 1 separates two upper pieces in front of needle drop position first, then sews, so that upper piece overlapping phenomenon does not appear, and sewing line is uniform, and upper piece is not overlapped, compared with prior art, the utility model discloses anti-overlapping needle plate for matching machine is used to carry out upper piece sewing operation, improves work efficiency, and reduces rework rate.

[0019] The above-mentioned is only the preferred implementation mode of the utility model, and it should be pointed out that, for those skilled in the art, without departing from the overall concept of the utility model, a number of changes and improvements can be made, and these should be regarded as the protection scope of the utility model.​
