[0049] Reference Figure 1-Figure 8, a circular knitting machine with a yarn lifting and adjusting function, comprising a large disc table 1, a transmission assembly 2, a shaft rod member 3, a knitting assembly 4 and a telescopic adjustment assembly 5, the large disc table 1 has a receiving cavity 11, the transmission assembly 2 is located in the receiving cavity 11, the transmission assembly 2 comprises a driver, a driving gear 21, a large disc gear 22 and a driven gear 23, the large disc gear 22 is located in the receiving cavity 11, the driving gear 21 and the driven gear 23 are respectively located in the receiving cavity 11 and mesh with the large disc gear 22, the large disc gear 22 is located at the center of the receiving cavity 11, and the driving gear 21 and the driven gear 23 are respectively located at the periphery of the large disc gear 22, the driver is located at the bottom of the large disc table 1 and connected to the driving gear 21, the driver is a servo drive motor in the prior art, and the driver provides power for the rotation of the driving gear 21, the driven gear 23 is sleeved on the shaft rod member 3, and the driven gear 23 can be rotated by sleeved, and the driving gear 21 is connected to the driven gear 23 through the large disc gear 22;

[0050] The knitting assembly 4 includes a disc 41, a needle cylinder 42 and a yarn feeding frame 43. The large disc gear 22 has a protrusion 221. The disc 41 is sleeved on the protrusion 221. The needle cylinder 42 is installed on the disc 41. The yarn feeding frame 43 is located above the needle cylinder 42. The needle cylinder 42 and the yarn feeding frame 43 are two very important components in the circular knitting machine. They each have different functions. The needle groove on the needle cylinder 42 is used to install the needles for knitting. The main function of the yarn feeding frame 43 is to provide yarn for the needles on the needle cylinder 42 for knitting.

[0051] The shaft member 3 has a cavity 31 in it, and a telescopic driving component 32 is arranged in the cavity 31. The telescopic driving component 32 includes a piston head 321 and a piston rod 322. The piston head 321 is movably arranged in the cavity 31 and fits with the inner wall of the cavity 31. The piston rod 322 is arranged on the piston rod 322. One end of the piston rod 322 extends to the outside of the driven gear 23 and abuts against the disc body 41. The bottom of the shaft member 3 is provided with a liquid inlet interface connected to the cavity 31. The liquid inlet interface is connected to an external hydraulic cylinder. When hydraulic oil is injected into the cavity 31, it can push the piston head 321 to move, so that the piston rod 322 is away from the shaft member 3.

[0052] The telescopic adjustment components 5 are provided with several and are arranged in a ring on the large plate table 1. The telescopic adjustment components 5 include a bearing seat 51 and a bracket seat 52. The yarn feeding frame 43 is arranged on the bracket seat 52. The bearing seat 51 has a slide groove 511. The bottom of the bracket seat 52 is provided with an extension portion 521. By embedding the extension portion 521 into the slide groove 511, when the extension portion 521 moves relatively in the slide groove 511, the height of the yarn feeding frame 43 changes synchronously. The distance between the yarn feeding frame 43 and the needle cylinder 42 affects the density and elasticity of the woven fabric. The bracket seat 52 has a mounting for the yarn feeding frame 43. The bracket seat 52 is also provided with a fastening bolt, and when part of the yarn feeding frame 43 is located in the slot 522, the fastening bolt is located above the yarn feeding frame 43. The setting of the slot 522 can enable the yarn feeding frame 43 to be quickly installed on the bracket seat 52, and the several bracket seats 52 are distributed in a ring shape, which can support the yarn feeding frame 43 from different positions, thereby improving the stability of the yarn feeding frame 43 when placed. When the yarn feeding frame 43 is located between the bottom of the slot 522 and the fastening bolt, the yarn feeding frame 43 can be fixed in the slot 522 by rotating the fastening bolt.

[0053] Based on the above structure, since the syringe 42 is installed on the disc body 41, and the disc body 41 is sleeved on the protrusion 221 of the large disc gear 22, when the driving gear 21 rotates under the cooperation of the driver, the driving gear 21 will drive the large disc gear 22 to rotate synchronously, and the large disc gear 22 will drive the remaining driven gears 23 to rotate synchronously during the rotation process. The driven gear 23 will again transmit the rotational force to the large disc gear 22 during the rotation process, so as to keep the large disc gear 22 rotating smoothly, thereby driving the disc body 41 to make the syringe 42 rotate synchronously. Since the disc body 41 is against the piston rod 322 in the shaft member 3 on the driven gear 23, the disc body 41 will contact with the piston rod 322 when rotating, and then due to the piston The rod 322 is connected to the piston head 321 located in the cavity 31, so when the hydraulic oil inputted by the hydraulic interface is poured into the cavity 31, the pressure of the liquid will drive the piston head 321 to move relatively, so that the piston rod 322 moves synchronously, and the piston rod 322 will drive the disc 41 to change its height position synchronously during the movement, so as to change the height of the needle cylinder 42. Since there is a certain distance between the needle cylinder 42 and the yarn feeding frame 43, when the height position of the needle cylinder 42 changes and makes it close to the yarn feeding frame 43, the yarn tension increases, the fabric density increases, and the coil is tightened, thereby reducing the elasticity of the woven fabric. When the needle cylinder 42 is away from the yarn feeding frame 43, the woven coil can be enlarged, the fabric becomes softer, and the coverage and warmth retention are increased.

[0054] The yarn feeding frame 43 is connected to the bracket seat 52 in the telescopic adjustment component 5, and the extension portion 521 on the bracket seat 52 is embedded in the slide groove 511 of the bearing seat 51. Therefore, the movement of the extension portion 521 in the slide groove 511 can further change the distance between the yarn feeding frame 43 and the syringe 42. Compared with the method of only controlling the height lifting of the syringe 42 to change the distance between the syringe 42 and the yarn feeding frame 43, the change of the height of the yarn feeding frame 43 can be controlled by the telescopic adjustment component 5. The spacing distance can be further expanded, so that it can be adjusted according to yarn cores of different properties. , thereby improving the overall flexibility of the circular knitting machine. Compared with the traditional method, when the circular knitting machine is working on the machine, the height distance between the needle cylinder 42 and the yarn feeding frame 43 is fixed, and when the distance needs to be changed, the machine must be stopped and adjusted manually. Through the cooperation of the telescopic driving component 32 and the telescopic adjustment component 5, the distance between the needle cylinder 42 and the yarn feeding frame 43 can be changed, thereby solving the problem that the existing circular knitting machine cannot adjust the distance between the needle cylinder 42 and the yarn feeding frame 43 during operation, and the manual operation requires relying on the operator's skills and experience, which is prone to deviations and leads to low efficiency.

[0055] In one embodiment, referring to Figure 1 , Figure 4 and Figure 6 , further comprising a heat dissipation assembly 6, a plurality of evenly distributed support arms 12 are arranged on the large plate table 1, a yarn coil bracket 121 is arranged on the support arm 12, the heat dissipation assembly 6 is arranged on the yarn coil bracket 121, the heat dissipation assembly 6 comprises a first push rod component 61, a material rack 62 and a fan component 63, the first push rod component 61 is arranged on the top of the yarn coil bracket 121, the piston end of the first push rod component 61 passes through the yarn coil bracket 121 and is connected to the material rack 62, the first push rod component 61 is a pneumatic push rod in the prior art, and the material rack 62 can be driven to move relatively through the first push rod component 61;

[0056] The fan component 63 is installed on the material rack 62. The fan component 63 is a fan component driven by a motor in the prior art. The air outlet end of the fan component 63 faces the large plate table 1. Through the cooperation of the first push rod component 61 and the material rack 62, the fan component 63 is moved close to or away from the large plate table 1. By adjusting the height of the fan component 63, the temperature change during the operation of the machine can be used to cool the heating area more effectively, so that the fan component 63 can be closer to the heat source. When the fan component 63 is raised or lowered to a position closer to the heat source, the air flow speed can be increased accordingly due to the shortened distance. The air flow speed can be increased while increasing the gas resistance, thereby improving the heat dissipation efficiency. The movement of the fan component 63 can optimize the distribution of the air flow in the entire working area, ensuring that there are no dead angles and every corner can be effectively cooled.

[0057] In one embodiment, referring to Figure 1 , Figure 4 , Figure 5 and Fig. 9 The telescopic adjustment assembly 5 also includes a second push rod component 53, which is located on one side of the bearing seat 51. The second push rod component 53 is a pneumatic push rod in the prior art, and the second push rod component 53 is connected to an external gas compressor. A connecting portion 531 is provided on the piston end of the second push rod component 53, and the connecting portion 531 is connected to the bracket seat 52;

[0058] Through the cooperation of the second push rod component 53 and the extension part 521, the support seat 52 drives the yarn feeding frame 43 to move closer to or away from the needle cylinder 42. A yarn feeding nozzle is arranged on the yarn feeding frame 43. The second push rod component 53 drives the extension part 521 to move, so that the distance between the support seat 52 and the bearing seat 51 can be accurately controlled, thereby changing the height of the yarn feeding frame 43, thereby realizing the adjustment of the density in the woven fabric.

[0059] In one embodiment, referring to Figure 1 , Figure 5 , Figure 7 , Figure 8 and Fig.10 The piston rod 322 is provided with a support pad 3221 at the portion outside the driven gear 23. When the disc body 41 is sleeved on the protruding portion 221, the bottom of the disc body 41 fits with the support pad 3221. The support pad 3221 is made of rubber material. By abutting against the disc body 41, the end face of the piston rod 322 can be prevented from being worn by the disc body 41 when it contacts with the disc body 41, and the support effect is further achieved.

[0060] The support pad 3221 is provided with symmetrically distributed recessed portions 32211, and a pulley component 7 is provided in the recessed portion 32211. The pulley component 7 includes a support rod 71 and a roller 72. The support rod 71 is arranged in the recessed portion 32211, and the roller 72 is movably arranged on the support rod 71. A part of the roller 72 is located outside the recessed portion 32211. When the disk body 41 is located on the support pad 3221, the outer periphery of the roller 72 fits with the disk body 41. Since the disk body 41 rotates synchronously with the cooperation of the large disk gear 22, in order to reduce the friction force generated when the disk body 41 rotates, a pulley component 7 is provided on the support pad 3221 in contact with the disk body 41, and the roller 72 on the pulley component 7 contacts with the disk body 41, so that the disk body 41 can provide thrust when rotating, thereby reducing the friction force required for rotation, and further improving the smoothness of the disk body 41 when rotating with the cooperation of the large disk gear 22.

[0061] In one embodiment, referring to Figure 3 , Figure 5 , Figure 7 and Figure 8 The accommodating cavity 11 has several evenly distributed mounting holes 111, and the shaft rods 3 are provided with several shaft rods 3 and are respectively movably arranged on the mounting holes 111. The height of the disk 41 is changed synchronously by the movement of the shaft rods 3 in the mounting holes 111. The height of the disk 41 is changed by the change of the height of the shaft rods 3 in the mounting holes 111;

[0062] A thread groove 1111 is provided on the inner wall of the mounting hole 111, and a convex thread 33 matching the thread groove 1111 is provided on the outer periphery of the shaft member 3. The thread groove 1111 and the convex thread 33 cooperate with each other, so that the shaft member 3 is threadedly connected to the mounting hole 111. The threaded connection can make the shaft member 3 firmly installed on the mounting hole 111 to avoid the shaft member 3 falling from the mounting hole 111. In addition, since the telescopic driving component 32 on the shaft member 3 is connected to the disk 41 carrying the needle cylinder 42, before the knitting operation is performed, the height of the shaft member 3 in the mounting hole 111 can be adjusted, and several shaft members 3 can be uniformly adjusted, so that the initial height of the needle cylinder 42 can be changed, so that it can be suitable for yarns with different characteristics, thereby improving the flexibility of use of the circular knitting machine.

[0063] In one embodiment, referring to Figure 5 , Figure 7 and Figure 8 The shaft member 3 also has a supporting plate 34, and the driven gear 23 is rotatably set on the supporting plate 34. The diameter of the supporting plate 34 is smaller than the diameter of the driven gear 23. The driven gear 23 is supported by the supporting plate 34, which can prevent the driven gear 23 from shaking during rotation, thereby causing the driven gear 23 to move along the length direction of the shaft member 3. The stability of the driven gear 23 during rotation is improved by limiting the position. The supporting plate 34 is located above the convex thread 33.

[0064] In one embodiment, referring to Figure 8 The cavity 31 has an inclined end portion 311, and the inclined end portion 311 is located at the bottom of the cavity 31. The setting of the inclined end portion 311 enables the inclined end portion 311 to guide the hydraulic oil in the cavity 31 to flow back into the bottom of the cavity 31 when the hydraulic oil flows back, and avoids the residual hydraulic oil, thereby avoiding the residual hydraulic oil from blocking the telescopic driving component 32, thereby affecting the movement accuracy.

[0065] In one embodiment, referring to Figure 1-Figure 3A plurality of evenly distributed tripods 13 are provided at the bottom of the large plate table 1, and a accommodating area is formed between the plurality of tripods 13. A cloth winding machine for winding the cloth is placed in the accommodating area, and a control console 131 is provided on one group of the tripods 13. The control console 131 is connected to the driver to control the rotation of the driving gear 21, and the control console 131 can electrically connect the gas compressor connected to the second push rod component 53 and the first push rod component 61, so as to control the first push rod component 61 and the second push rod component 53, so as to change their telescopic lengths, so that the operator can detect the operation status of the setting through the control console 131 externally.
