Abstract
The invention discloses a bilateral cloth feeding tooth pin, which is provided with a tooth holder, wherein one end of the tooth holder is provided with a rectangular notch; three groups of oblique teeth are arranged in parallel on the rectangular notch; the lengths of the oblique teeth in a middle row are smaller than the lengths of the oblique teeth on both sides; positioning holes are formed in the tooth holder; and at least two positioning holes are formed. The bilateral cloth feeding tooth pin has the advantages that cloth feeding and returning can be realized through the oblique teeth, the cloth is prevented from being corrugated in a conveying process, the processing quality is improved, and the appearance of sewing lines is ensured.
Description
Technical field
The present invention relates to a kind of Sewing machines tooth pin, relate in particular to a kind of two-way feed dog pin.
Background technology
In the Sewing machines process, can evenly move forward in the process of making in order to make cloth, the sewing machine needle below is provided with the feed dog pin.Existing sewing machine feed dog pin all is a check configuration, therefore work feed forward, in case phenomenons such as broken string or broken needle appear in the process of making, and need be with the manually retracted original position of cloth, process, in manually moving back the cloth process, occur problems such as cloth deflection or fold easily.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of can self-feeding and the two-way feed dog pin of the material returned.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of two-way feed dog pin, have the tooth seat, and described tooth seat one end is provided with rectangular notch, be set side by side with three groups of helical teeth on the rectangular notch, and a middle row helical teeth length is less than the helical teeth length of its both sides.
For the ease of fixing, preferred, described tooth seat is provided with locating hole.
Preferably, described locating hole has two at least.
Compared with prior art, usefulness of the present invention is: this two-way feed dog pin can be realized the charging and the material returned of cloth by helical teeth, guarantees that cloth gauffer can not occur in transport process, improves crudy, guarantees to make the attractive in appearance of lines.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a kind of two-way step presser foot schematic diagram that send of the present invention.
Among the figure: 1, tooth seat; 2, helical teeth; 3, locating hole; 4, rectangular notch.
The specific embodiment:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of two-way feed dog pin shown in Figure 1 has tooth seat 1, and described tooth seat 1 one ends are provided with rectangular notch 4, are set side by side with three groups of helical teeth 2 on the rectangular notch 4, and a middle row helical teeth 2 length are less than helical teeth 2 length of its both sides; For the tooth pin being fixed on the Sewing machines, be provided with two locating holes 3 on the described tooth seat 1 at least.
This two-way feed dog pin can be realized the charging and the material returned of cloth by helical teeth 2, guarantees that cloth gauffer can not occur in transport process, improves crudy, guarantees to make the attractive in appearance of lines.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
