Furthermore, a groove avoiding zipper teeth is formed in the middle of the bottom surface of the material pressing head, and the end surface of the zipper strip is faced with the bottom surface of the zipper strip and is rounded.

Further, one end, facing the zipper strips, of the groove is expanded outwards to form a horn mouth.

Further, a pressure regulating valve is installed on the tensioning cylinder.

Further, a light eye is fixedly arranged on the mounting plate, and the control device can control the action of the tensioning cylinder after receiving a signal of the light eye.

Compared with the traditional manual sewing, the utility model discloses the simulation hand supports presses the zip fastener strip and gets into the sewing machine gently and make up, replaces original hand labor, can alone see two machines, has improved production efficiency, has reduced manufacturing cost, can not have the human error because of fatigue and other reasons lead to, and need not skilled worker's operation, and the hands are all operatable, have reduced the requirement to workman's skill, have practiced thrift the human cost, and the clothes standard of making up is unified unanimous, makes up the effect pleasing to the eye.

Detailed Description

In the description of the present invention, it is to be understood that the terms "left", "right", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplified description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation. The terms "first", "second", etc. are used merely to distinguish different elements and should not be construed as limiting the invention.

In the description of the present invention, unless otherwise specified, "a plurality" means two or more unless explicitly defined otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixedly connected" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; unless the movable connection is explicitly defined as a detachable connection. These connections are conventional in the art, and those skilled in the art will understand the specific meaning of the above terms in the present invention according to the specific situation.

The zipper tensioning mechanism shown in fig. 1-4 comprises an additional table plate 14 fixedly connected with a sewing machine table plate 13 and flush with the sewing machine table plate 13, wherein the additional table plate 14 is fixedly connected with a limiting groove 15 corresponding to the position of a sewing machine needle plate, and the limiting groove 15 is connected with a synchronous belt 3 for conveying a zipper 4 and allows the zipper 4 to enter; the rigid coupling mounting panel 16 on sewing machine 11's the aircraft nose, rigid coupling axial vertical taut cylinder 17 on the mounting panel 16, the air-vent valve of installation on the taut cylinder 17, rigid coupling pressure stub bar 18 on taut cylinder 17's the jar pole, pressure stub bar 18 can separate draw zipper strip 4 with the tank bottom butt of spacing groove 15. The middle part of the bottom surface of the material pressing head 18 is provided with a groove 181 avoiding zipper teeth, and one end of the groove 181 facing the zipper strip 4 is outwards expanded into a horn mouth 183. The end surface facing the zipper strip 4 and the bottom surface are rounded 182. A photo eye 12 is fixed on the mounting plate 16, and a control device (not shown) can control the action of the tensioning cylinder 17 after receiving the signal of the photo eye 12.

In the actual production process, the motor 2 drives the synchronous belt 3 to rotate, the zipper strips 4 are placed on the synchronous belt 3 one by one through manpower or machines, the first zipper strip 4 is gradually close to the vertical baffle 5 along with the motion of the synchronous belt 3, even if the zipper strip 4 is not placed right, after the zipper strip 4 is abutted to the vertical baffle 5, the length direction of the zipper strip 4 is kept consistent with the length direction of the vertical baffle 5 along with the motion of the synchronous belt 3, at the moment, the control device controls the motor 2 to stop running, the carriage 10 drags the zipper strip 4 to enter the limiting groove 15 and enter a needle plate of the sewing machine, the sewing machine starts to sew, the feed dog of the sewing machine starts to drag the zipper strip 4, meanwhile, after the bright eye 12 senses the zipper strip 4, the control device controls the tensioning cylinder 17 to move downwards to drive the pressure material head 18 to abut against the zipper strip 4 in the limiting groove 15, and as the zipper strip 4 is subjected to the tension of the feed dog of the sewing machine on one hand, on the other hand, the friction force generated by the pressing of the material pressing head 18 is combined to obtain the pulling force simulating the hand of a person, and the pressure is adjusted by the pressure adjusting valve to simulate the strength of the hand of the person.

When the zipper strip is separated from the material pressing head 18, the light eye 12 cannot sense the zipper strip 4, and the control device controls the tensioning cylinder 17 to move upwards to reset. When the light eye 12 senses the next zipper strip, the above process is repeated, and the process is repeated in a circulating manner.
