[0003] However, most of the large circular knitting machines on the market currently have fixed needle cylinders, which makes it difficult to adjust the depth and height of the knitting needles when facing different hooking depths on the surface of knitted fabrics. When faced with this phenomenon, the needle cylinder is generally replaced directly, and the equipment needs to be stopped when the needle cylinder is replaced, which leads to lower efficiency in processing knitted fabrics. Moreover, after the knitting needles have been used for a long time, their surfaces will be worn due to long-term friction with the knitted fabrics, making their replacement more inconvenient.

[0007] As a further improvement of the above solution, the mounting blocks are distributed in a circular array on the top of the syringe housing, and the support blocks are symmetrically distributed up and down with the syringe housing as the axis.
[0008] As a further improvement of the above scheme, the lifting mechanism includes a limit plate, which is slidably connected to the outer wall of the syringe housing, and the limit plate is symmetrically distributed around the lifting mechanism. A slider is fixedly connected to one side of the limit plate close to the first adjusting bolt.
[0009] As a further improvement of the above scheme, the slider is meshed and rotatably connected to the first adjusting bolt, a pointer cutter head is fixedly connected to one side of the lifting mechanism, a knitting needle slot is provided on one side of the lifting mechanism relative to the pointer cutter head, and a through hole is provided inside the lifting mechanism.
[0010] As a further improvement of the above scheme, the through holes are symmetrically distributed with the knitting needle slot as the axis, the pointer bit is in contact with the scale mark, and the fixing mechanism includes a pressure plate, which is in contact with the knitting needle.
[0011] As a further improvement of the above solution, a sliding rod is fixedly connected to one side of the pressure plate close to the pointer blade head, the sliding rods are symmetrically distributed with the pressure plate as the axis, and the sliding rods are slidably connected to the through hole.
[0012] As a further improvement of the above solution, the end of the sliding rod away from the pressure plate is fixedly connected to a support plate, the internal rotation of the support plate is connected to a second adjusting bolt, and the end of the second adjusting bolt away from the support plate is connected to the internal rotation of the lifting mechanism.
[0013] The utility model has the following beneficial effects:
[0014] 1. The adjustable needle cylinder device for a large circular knitting machine, when the knitting needle is used for a long time, the surface of the knitting needle will be worn due to the long-term friction between the surface and the knitted fabric. By rotating the second adjusting bolt, the support plate slides along the surface of the second adjusting bolt, thereby driving the pressure plate to move away from the knitting needle slot through the slide bar, and then the knitting needle is inserted into the inside of the knitting needle slot. At the same time, the second adjusting bolt is reversed, so that the support plate slides in the opposite direction along the surface of the second adjusting bolt, thereby driving the pressure plate to gradually approach the knitting needle slot through the slide bar. When the pressure plate contacts the surface of the knitting needle, the rotation of the second adjusting bolt can be stopped, and the knitting needle can be fixed at this time. This arrangement can realize the replacement of the knitting needle, reducing the replacement time, and also reducing the use cost of the needle cylinder by replacing a single part.
[0015] 2. This circular knitting machine uses an adjustable needle cylinder device. By rotating the twist cap, the twist cap drives the first adjusting bolt to rotate, so that the sliding block engaged with the rotating surface of the first adjusting bolt drives the lifting mechanism to move upward as a whole, thereby completing the adjustment of the knitting needle height, so that the knitting needles on the needle cylinder can be adjusted, effectively improving the adjustment efficiency. At the same time, the scale mark set on the front of the needle cylinder shell allows the lifting mechanism to observe the current height value through the pointer blade during the rising process, so that the height adjustment of the knitting needle is more precise, thereby improving the quality of the knitting process.
[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

[0027] The mounting blocks 2 are distributed in a circular array on the top of the syringe housing 1, and the support blocks 3 are distributed symmetrically up and down with the syringe housing 1 as the axis.
[0028] The lifting mechanism 8 includes a limit plate 801 , which is slidably connected to the outer wall of the syringe housing 1 . The limit plates 801 are symmetrically distributed around the lifting mechanism 8 , and a slider 802 is fixedly connected to one side of the limit plate 801 close to the first adjusting bolt 6 .
[0029] The slider 802 is meshed and rotatably connected to the first adjusting bolt 6. A pointer blade 803 is fixedly connected to one side of the lifting mechanism 8. A needle slot 804 is provided on one side of the lifting mechanism 8 relative to the pointer blade 803. A through hole 805 is provided inside the lifting mechanism 8.
[0030] The through holes 805 are symmetrically distributed with the knitting needle slot 804 as the axis, the pointer blade 803 is in contact with the scale mark 9, and the fixing mechanism 11 includes a pressing plate 111, which is in contact with the knitting needle 10.
[0031] A slide bar 112 is fixedly connected to one side of the pressure plate 111 close to the pointer blade 803 . The slide bar 112 is symmetrically distributed around the pressure plate 111 . The slide bar 112 is slidably connected to the through hole 805 . The symmetrical arrangement of the slide bar 112 makes the movement of the pressure plate 111 more stable.
[0032] One end of the slide rod 112 away from the pressure plate 111 is fixedly connected to the support plate 114, and the internal rotation of the support plate 114 is connected to the second adjusting bolt 113. The end of the second adjusting bolt 113 away from the support plate 114 is connected to the internal rotation of the lifting mechanism 8.

[0033] A specific application of this embodiment is:
[0034] When the staff needs to use the device, they first fix the mounting block 2 on the top of the needle cylinder housing 1 to the large circular knitting machine through the mounting bolts, and then rotate the second adjusting bolt 113 to make the support plate 114 slide along the surface of the second adjusting bolt 113, thereby driving the pressing plate 111 to move away from the knitting needle slot 804 through the sliding rod 112, and then insert the knitting needle 10 into the inside of the knitting needle slot 804, and at the same time reverse the second adjusting bolt 113 to make the support plate 114 slide in the opposite direction along the surface of the second adjusting bolt 113, thereby driving the pressing plate 111 to gradually approach the knitting needle slot 804 through the sliding rod 112. When the pressing plate 111 contacts the surface of the knitting needle 10, the rotation of the second adjusting bolt 113 can be stopped, and the knitting needle 10 can be fixed at this time. After the knitting needle 10 is used for a long time, due to the long-term friction between its surface and the knitted fabric, it will cause The surface of the knitting needle 10 is worn, and this arrangement can be used to replace the knitting needle 10, which reduces the replacement time. The replacement of a single part also reduces the cost of using the syringe. After the knitting needle 10 is fixed, it is usually necessary to adjust the distance between the knitting needle and the textile under the drive of the large circular knitting machine, so as to adjust the length of the hooking line on the textile surface, so as to adapt to the requirements of the hooking line depth on the surface of different textiles. Specifically, by rotating the twist cap 7, the twist cap 7 drives the first adjusting bolt 6 to rotate, so that the sliding block 802 engaged and rotating on the surface of the first adjusting bolt 6 drives the lifting mechanism 8 to move upward as a whole, thereby completing the adjustment of the height of the knitting needle 10, so that the knitting needle 10 on the syringe can be adjusted, which effectively improves the efficiency of the adjustment. At the same time, the scale mark 9 set on the front side of the syringe housing 1 allows the lifting mechanism 8 to observe the current height value through the pointer blade 803 during the rising process.
