[0001] The utility model belongs to the technical field of circular knitting machines, in particular to an angle adjustment device for circular knitting machines. Background Art
[0002] Circular knitting machines are widely used in the fields of clothing, home textiles, industrial textiles, etc. In the field of clothing, circular knitting machines can produce various styles of knitted clothing, such as sweaters, T-shirts, sportswear, etc.
[0003] At present, the relative position of the textile needles and the needle disk used in large circular knitting machines is usually fixed. When facing different textiles, the textile angle needs to be adjusted to adapt to the textile needs of different textiles. However, since the angle between the textile needles and the needle disk is fixed, it is necessary to replace parts to meet the textile needs. When replacing parts, the large circular knitting machine needs to be stopped, which reduces the working efficiency of the large circular knitting machine. At the same time, frequent replacement of parts will also cause equipment wear, resulting in a decrease in the quality of textile knitting on the large circular knitting machine. Utility Model Content
[0004] The utility model aims to provide an angle adjustment device for a circular knitting machine, which effectively solves the problem that the angle between the knitting needle and the needle disc is difficult to adjust by arranging a longitudinal adjustment mechanism, a threaded rod and a transverse adjustment mechanism.
[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0006] The utility model discloses an angle adjustment device for a large circular knitting machine, comprising a base, an upper surface of the base being fixedly connected with a mounting pad, an upper surface of the base being provided with a longitudinal adjustment mechanism, an inner rotation connection of the base being provided with a rotating rod, the rotating rods being symmetrically distributed with the base as an axis, a top side of the rotating rod being fixedly connected with a docking rod, an end of the docking rod being fixedly connected with a docking plate, a fixing frame being fixedly connected with the same side of the rotating rod and the docking rod, an inner rotation connection of the rotating rod being provided with a threaded rod, a surface of the threaded rod being provided with a transverse adjustment mechanism, a bottom of the transverse adjustment mechanism being fixedly connected with a needle cylinder, and a knitting needle being inserted with a knitting needle at the bottom of the needle cylinder.
[0007] As a further improvement of the above scheme, the longitudinal adjustment mechanism includes a support plate, the bottom of the support plate is fixedly connected to the upper surface of the base, the top of the support plate is fixedly connected to an adjustment frame, one side of the adjustment frame is fixedly connected to an arc-shaped scale plate, and a slide groove is opened on the top of the adjustment frame.
[0008] As a further improvement of the above scheme, a slider is slidably connected inside the slide groove, the outer wall of the slider is in contact with the outer wall of the adjustment frame, and a pointer is fixedly connected to the side of the slider close to the arc-shaped scale plate, and the pointer is in contact with the arc-shaped scale plate.
[0009] As a further improvement of the above scheme, a guide rod is fixedly connected to the bottom of the slider, and the guide rod is slidably connected to the inner wall of the adjustment frame. Both ends of the guide rod are fixedly connected to docking plates. The side of the slider away from the pointer is rotatably connected to a fastening bolt, and the fastening bolt passes through the inside of the slider to the outer wall of the adjustment frame.
[0010] As a further improvement of the above scheme, a limiting ring is fixedly connected to the surface of the threaded rod, and the limiting ring is symmetrically distributed with the threaded rod as the axis. One end of the threaded rod is fixedly connected to a torsion rod, and the torsion rod is in contact with the outer wall of the rotating rod.
[0011] As a further improvement of the above scheme, the lateral adjustment mechanism includes a ring, which is meshed and rotatably connected with the surface of the threaded rod, and fixed blocks are fixedly connected to both sides of the ring, and the ends of the fixed blocks are fixedly connected to limiting caps.
[0012] As a further improvement of the above scheme, the surface of the fixed block is slidably connected to a limiting plate, the side of the limiting plate close to the ring is fixedly connected to a rotating shaft, the rotating shaft is rotatably connected to the fixed frame, and the bottom of the limiting plate is fixedly connected to the top of the syringe.
[0013] The utility model has the following beneficial effects:
[0014] 1. The angle adjustment device for a large circular knitting machine, when adjusting the knitting needle angle, first loosen the fastening bolt to release the slider from the adjustment frame. At this time, according to the actual longitudinal angle requirement, the rotating rod is pushed to rotate inside the base. At the same time, the rotation of the rotating rod will drive the rotation of the docking rod. Because the docking rod and the guide rod are fixedly docked through the docking plate, the docking rod can drive the guide rod to rotate synchronously while rotating. Because the guide rod is fixedly connected to the slider, the slider and the guide rod rotate synchronously. Due to the arc-shaped scale plate, the slider can be combined with the pointer on one side to observe the currently adjusted angle value in real time when it rotates, so that the longitudinal angle adjustment is more accurate, and the needle accuracy is improved while the subsequent textile quality is effectively improved. After the longitudinal angle adjustment is completed, the fastening bolt is re-tightened so that the slider is re-locked on the outer wall of the adjustment frame, thereby avoiding the longitudinal angle from being offset due to sliding.
[0015] 2. The angle adjustment device for a large circular knitting machine adjusts the lateral angle according to actual needs after completing the adjustment of the longitudinal angle. Specifically, the torsion rod is first rotated to make the torsion rod drive the threaded rod to rotate inside the rotating rod. When the threaded rod rotates, the collar on its surface will move laterally along the surface of the threaded rod. The moving direction depends on the rotation direction of the threaded rod. During the sliding of the collar, the limit cap will be driven to slide inside the limit plate. At the same time, during the sliding of the limit cap, a thrust will be generated on the limit plate, so that the limit plate drives the rotating shaft to rotate inside the fixed frame. When the limit plate rotates, the needle cylinder and the knitting needle at the bottom thereof will be driven to change the lateral angle. The cooperation between the threaded rod and the collar makes the entire lateral movement smoother, and when the fine-tuning threaded rod rotates, the collar will still move, which makes the adjustment sensitivity higher and can meet the high-precision angle adjustment. With the use of the longitudinal adjustment mechanism, the knitting needle angle can be adjusted, thereby increasing the range of angle adjustment.
[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

A pointer 306 is fixedly connected to the side of the slider 305 close to the arc scale plate 303, and the pointer 306 is in contact with the arc scale plate 303. Due to the setting of the arc scale plate 303, the slider 305 can rotate and combine with the pointer 306 on one side thereof, so that the currently adjusted angle value can be observed in real time, making the longitudinal angle adjustment more precise.
[0029] A guide rod 307 is fixedly connected to the bottom of the slider 305, and the guide rod 307 is slidably connected to the inner wall of the adjustment frame 302.

[0033] A specific application of this embodiment is:
[0034] When the staff needs to use the device, when adjusting the angle of the knitting needle 11, first loosen the fastening bolt 308 to release the slider 305 from the adjustment frame 302. At this time, according to the actual longitudinal angle requirement, the rotating rod 4 is pushed to rotate the rotating rod 4 inside the base 1. At the same time, the rotation of the rotating rod 4 will drive the rotation of the docking rod 5. Because the docking rod 5 and the guide rod 307 are fixedly docked through the docking plate 6, the docking rod 5 can drive the guide rod 307 to rotate synchronously while rotating. Because the guide rod 307 and the slider 305 are fixed, The slider 305 is connected to the guide rod 307 so that the slider 305 rotates synchronously with the guide rod 307. Due to the arc-shaped scale plate 303, the slider 305 can be combined with the pointer 306 on one side to observe the currently adjusted angle value in real time while rotating, so that the longitudinal angle adjustment is more accurate, the needle accuracy is improved, and the subsequent textile quality is effectively improved. After the longitudinal angle adjustment is completed, the fastening bolt 308 is re-tightened so that the slider 305 is re-locked on the outer wall of the adjustment frame 302, thereby avoiding the longitudinal angle from being offset due to sliding. After completing the adjustment of the longitudinal angle, the lateral angle is adjusted according to actual needs. Specifically, first rotate the torsion bar 802 so that the torsion bar 802 drives the threaded rod 8 to rotate inside the rotating rod 4. When the threaded rod 8 rotates, the collar 901 on its surface will move laterally along the surface of the threaded rod 8. The movement direction depends on the rotation direction of the threaded rod 8. During the sliding of the collar 901, the limit cap 903 will be driven to slide inside the limit plate 904. At the same time, during the sliding of the limit cap 903, a thrust will be generated on the limit plate 904, so that the limit plate 904 drives the rotating shaft 905 to rotate inside the fixed frame 7. When the limit plate 904 rotates, it will drive the needle cylinder 10 and the knitting needle 11 at the bottom thereof to change the lateral angle. The cooperation between the threaded rod 8 and the ring 901 makes the entire lateral movement more stable, and when the fine-tuning threaded rod 8 rotates, the ring 901 will still move, which makes the adjustment sensitivity higher and can meet the high-precision angle adjustment. With the use of the longitudinal adjustment mechanism 3, the knitting needle 11 can be adjusted 360 degrees, which increases the range of angle adjustment.
