Detailed Description
The technical scheme of the invention is clearly and completely described below by means of specific embodiments in combination with the accompanying drawings.
Referring to fig. 1-4, a middle corner structure includes a middle corner base 20, a middle corner 21, a middle corner cover 22, a needle-lifting knife 23 and a needle-pressing knife 24. The middle corner base 20 is fixedly arranged on one side of the needle cylinder, and the middle corner 21 is fixedly arranged on the middle corner base 20. The middle corner cover 22 is rotatably disposed above the middle corner 21. The needle-lifting knife 23 and the needle-pressing knife 24 are both movably arranged below the middle edge angle 21. The needle lifting knife 23 has a needle lifting surface which is inclined upward for lifting the stitch of the surface needle. The needle-pressing knife 24 has a needle-pressing surface which is inclined downward for pressing down the stitch of the face needle so that the face needle does not eat the thread. The term "thread-feeding" means that the surface needle hooks the thread, thereby knitting. In the structure of the central edge angle, a needle lifting knife 23 and a needle pressing knife 24 are added below the central edge angle 21, and the lower needle can be lifted or pressed according to the requirement during or after the knitting. The needle lifting knife 23 and the needle pressing knife 24 are movable, so that the needle lifting knife 23 or the needle pressing knife 24 can be conveniently pushed in or pushed out according to knitting requirements, the control is flexible, the functions are various, and the needle lifting knife is suitable for different knitting environments.
The middle angular structure 2 further comprises a first spring 25, a second spring 26, a third spring 291, a first cylinder 27, a second cylinder 28 and a third cylinder 29. The first spring 25 is provided between the needle knife 23 and the middle angular base 20, and is used for resetting the needle knife 23. The first cylinder 27 is connected to the needle-lifting knife 23 for controlling the movement of the needle-lifting knife 23. The needle knife 23 can be pushed out or retracted relative to the middle angular base 20. When the surface needle needs to be lifted, the first air cylinder 27 sucks air to control the needle lifting knife 23 to push out, and the surface needle is lifted to a certain height through the needle lifting surface. When the surface needle does not need to be lifted or after knitting is finished, the first air cylinder 27 is deflated, and the needle-lifting knife 23 is retracted by the rebound force of the first spring 25. The middle angular structure 2 is additionally provided with the needle pressing knife 24, and the needle pressing knife 24 and the needle lifting knife 23 are movably arranged on the middle angular base 20, so that socks can be conveniently transferred after knitting is finished, and the miniaturization of a hosiery machine is facilitated.
The second spring 26 is disposed between the needle-pressing knife 24 and the middle angular base 20, and is used for resetting the needle-pressing knife 24. The second air cylinder 28 is connected with the needle pressing knife 24 and is used for controlling the needle pressing knife 24 to move. The needle-pressing knife 24 can be pushed out or retracted relative to the middle angular base 20, and the push-out has two gears, namely half-gear push-out or full-gear push-out, that is, the needle-pressing knife 24 has three gears of half-gear push-out, full-gear push-out and full-gear retraction. When the half gear is pushed out, the surface needle with the high stitch can be pressed down, so that the surface needle with the high stitch can not eat the thread for knitting; while the face needle with low stitch is not depressed, so that the face needle with low stitch can eat the thread knitting. The needle with low stitch can be used for taking one more thread, so that the sock can be thickened. When the bottoms of the feet of the socks are knitted, the socks can be thickened by controlling the needle pressing knife 24 to push out in a half way, and the warmth retention property is improved. After knitting is completed, the needle pressing knife 24 is pushed out in a full-stop manner, and all the face needles can be fully pressed down and reset. After that, the needle-pressing knife 24 is retracted fully, the sock is lifted and transferred to the stitch for stitching, and the needle-pressing knife 24 is retracted to avoid blocking the sock from transferring.
The third cylinder 29 is connected to one end of the middle angular cover 22 to control the rotation of the middle angular cover 22. The third spring 291 connects the middle corner cover 22 and the middle corner base 20 to reset the middle corner cover 22. According to the different types of the knitted socks and the thickness of the needle thread, the distance between the middle edge angle cover 22 and the middle edge angle 21 can be adjusted so as to adapt to different use environments. The first, second and third cylinders 27, 28 and 29 are cylinders of the same type structure, and include a cylinder block 271 and a cylinder core top 272 movably disposed in the cylinder block 271.
The middle angular cover 22 is triangular, which is beneficial to lifting the needle to a certain height and pressing the needle below the triangle.
Although the present invention has been described in terms of the preferred embodiments, it is not intended to be limited to the embodiments, and any person skilled in the art can make any possible variations and modifications to the technical solution of the present invention by using the methods and technical matters disclosed above without departing from the spirit and scope of the present invention, so any simple modifications, equivalent variations and modifications to the embodiments described above according to the technical matters of the present invention are within the scope of the technical matters of the present invention.
