Description
Technical Field
The invention relates to the field of sewing, in particular to a differential tooth.
Background
Garment enterprises produce top fly, round neck shirts and casual upper garments with roll-ups worn in summer, which are all on the surface of the garment, and the doing quality is easy to see. The rolling hem is a procedure that the clothing is difficult to attack, the clothing is uneven when being made, and the clothing is not fast when being made flat. The auxiliary tool used at present can not fundamentally solve the problem of starting torsion in the working procedure, and staff is required to overcome the problem by using special gestures and technologies, so that great requirements are imposed on the gestures and technologies of the workers. Currently, the existing machines are limited in regulation and control, and the aim of debugging the sewing machine to the level required by customers is almost impossible. Therefore, the process of making the roll lower hem is very dependent on the operation technology of staff. The staff is required to cultivate the technology, and the staff requiring the skill of the clothing factories are many, but the short-time cultivation does not reach the operation technical standard.
Disclosure of Invention
Based on the technical problems existing in the background technology, the invention provides a differential tooth.
The invention provides a differential tooth, which comprises a tooth seat, at least one first supporting plate, an installation seat and at least one second supporting plate;
the tooth seat is provided with a mounting surface, the position of the first supporting plate corresponding to the mounting surface is arranged on the tooth seat, and one side of the first supporting plate, which is far away from the tooth seat, is provided with a first tooth slot;
the mount pad rotatable mounting is on the tooth seat, and the second backup pad is installed on the mount pad, and the first backup pad of second backup pad is parallel, and one side that the mount pad was kept away from to the second backup pad is equipped with a plurality of second tooth's sockets, and the mount pad rotates and can make the second backup pad keep away from the distance between mount pad one side and the installation face equal to the distance between first backup pad and the tooth seat one side and the installation face of keeping away from.
Preferably, one first support plate is provided and three second support plates are provided.
Preferably, the first support plate and the second support plate are both provided.
Preferably, the differential tooth further comprises a screw, a threaded hole matched with the screw is formed in the tooth seat, the screw is arranged on the tooth seat at the position corresponding to the threaded hole, and the screw can be abutted against the mounting seat in a rotating mode.
When common cloth is sewn, the mounting seat is rotated until the distance between one side, far away from the mounting seat, of the second support plate and the mounting surface is equal to the distance between one side, far away from the tooth seat, of the first support plate and the mounting surface, and therefore the first support plate and the second support plate are in contact with the cloth, uniform sewing of the cloth is achieved, when the hemming exists, the mounting seat is rotated, the second support plate cannot be in contact with the cloth, two layers of hemming positions are formed, the situation that the two layers of the hemming positions are stressed differently after the mounting seat is rotated, torsion is caused by the fact that the two layers of stress are not different is avoided, and the first support plate continuously pushes the adjacent parts of the hemming, so that the sewing of the hemming positions is rapidly and smoothly achieved. The sewing machine has a simple structure, realizes rapid and smooth sewing of the curled edge, can be put into the existing sewing machine for use, and effectively saves the cost of enterprises.
Drawings
Fig. 1 is a schematic view of a differential tooth structure according to the present invention.
Detailed Description
Referring to fig. 1, the differential tooth provided by the invention comprises a tooth socket 1, at least one first supporting plate 2, a mounting seat 3, at least one second supporting plate 4 and a screw 5;
the dental socket 1 is provided with a mounting surface 11, the position of the first support plate 2 corresponding to the mounting surface 11 is arranged on the dental socket 1, and a first tooth slot 21 is arranged on one side of the first support plate 2 away from the dental socket 1;
the mount pad 3 is rotatably installed on the dental socket 1, and second backup pad 4 is installed on the mount pad 3, and second backup pad 4 first backup pad 2 is parallel, and one side that second backup pad 4 kept away from the mount pad 3 is equipped with a plurality of second tooth grooves 41, and mount pad 3 rotation can make the distance between second backup pad 4 and the mount pad 3 side and the installation face 11 equal to the distance between first backup pad 2 and the dental socket 1 side and the installation face 11.
Screw holes matched with the screws are formed in the dental seat 1, the screws 5 are arranged on the dental seat 1 at positions corresponding to the screw holes, and the screws 5 can abut against the mounting seats 3 in a rotating mode.
When ordinary cloth is sewn, the mounting seat is rotated until the distance between the side, away from the mounting seat 3, of the second support plate 4 and the mounting surface is equal to the distance between the side, away from the dental seat 1, of the first support plate 2 and the mounting surface, and therefore, the first support plate 2 and the second support plate 4 are in contact with the cloth, uniform sewing of the cloth is achieved, when the hemming is carried out, the mounting seat 3 is rotated, the second support plate 4 cannot be in contact with the cloth, two layers of hemming positions are arranged, the situation that two layers of stress are different at the hemming positions after the mounting seat 3 is rotated, torsion is caused is avoided, the first support plate 2 continues to push the adjacent positions of the hemming, and the hemming positions can be quickly and smoothly sewn. The screw 5 can adopt the butterfly screw, rotate the mount pad 3 that can convenient and fast through the butterfly screw, will increase the cost because of need throw in new driving device like this, mount pad 3 can set up two at least internal thread grooves with screw looks adaptation, screw 5 can be more accurate fix mount pad 3, there are first position state and second position state at least when screw 5 and internal thread groove cooperate, first position state is that the distance between the mount pad 3 side was kept away from to second backup pad 4 and the installation face equals that the distance between the mount pad 1 side was kept away from to first backup pad 2 and the installation face equals, second position state is that second backup pad 4 does not contact the position state of cloth in the sewing process.
In this embodiment, the first support plate 2 is provided with one, the second support plate 4 is provided with three or the first support plate 2 and the second support plate 4 are provided with two, so that the structure and the sewing effect of the existing sewing machine are not affected while common cloth and cloth with curled edges can be sewn.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
