[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] See also Figure 1-5The utility model provides a technical solution: a double-sided large circular knitting machine that is convenient for needle replacement, comprising a large circular knitting machine body 1 and an annular carrier plate 2, the annular carrier plate 2 is bolted to the top of the large circular knitting machine body 1, a lifting mechanism 3 is arranged at the bottom of the annular carrier plate 2 for conveniently replacing the needle inside the large circular knitting machine body 1, and a protective component 4 is arranged inside the annular carrier plate 2 to increase the safety of maintenance personnel;

[0031] The lifting mechanism 3 includes a motor 301, a screw rod 302, a screw barrel 303, a limit groove 304, a limit rod 305 and a needle plate 306. The motor 301 is bolted to the bottom of the annular carrier plate 2, the screw rod 302 is fixedly connected to the output end of the motor 301, the screw barrel 303 is threadedly connected to the outside of the screw rod 302, the limit groove 304 is opened on the outer wall of the screw barrel 303, the limit rod 305 is bolted to the inner wall of the annular carrier plate 2, and the needle plate 306 is bolted to the bottom of the screw barrel 303.

[0032] In this embodiment: by setting the motor 301, the screw rod 302, the screw barrel 303, the limiting groove 304, the limiting rod 305 and the needle plate 306, when the needle on the needle plate 306 needs to be replaced, the maintenance personnel can cut off the power supply of the large circular knitting machine body 1 to prevent the large circular knitting machine body 1 from accidentally starting, and then start the motor 301. The motor 301 drives the screw rod 302 to rotate. Because the screw rod 302 is threadedly connected to the screw barrel 303, the screw rod 302 rotates and drives the screw barrel 303 and the needle plate 306 to rise. Then the limiting rod 305 slides inside the limiting groove 304 to prevent the screw barrel 303 from rotating with the screw rod 302. When the needle plate 306 is raised to a suitable height, the maintenance personnel can replace the needle at the bottom of the needle plate 306. After the replacement is completed, the above steps can be reversed.

[0033] As a technical optimization solution of the present invention, the protection component 4 includes a vertical rod 401 and a stabilizing plate 402 . The vertical rod 401 is evenly distributed on the inner bottom wall of the annular loading plate 2 , and the stabilizing plate 402 is bolted to the top of the vertical rod 401 .

[0034] In this embodiment: by providing a vertical rod 401 and a stabilizing plate 402, when the maintenance personnel replace the needle, the coordinated use of the vertical rod 401 and the stabilizing plate 402 can effectively limit the position of the maintenance personnel, preventing the maintenance personnel from excessive movement and causing the maintenance personnel to come into contact with other needles, resulting in the maintenance personnel being pricked, thereby improving the safety when replacing the needle.

[0035] As a technical optimization solution of the utility model, a ladder 5 is bolted to the outer wall of the large circular knitting machine body 1 for maintenance personnel to change needles. The number of the ladders 5 is five and they are evenly distributed.

[0036] In this embodiment, by providing a ladder 5, when the maintenance personnel replace the needle, the maintenance personnel can climb the ladder 5, so that the maintenance personnel are closer to the position of the needle, which is convenient for the maintenance personnel to replace the needle and increases the efficiency of replacing the needle.

[0037] As a technical optimization solution of the present invention, an antistatic layer is provided on the outer walls of the vertical rod 401 and the stabilizing plate 402 .

[0038] In this embodiment, an antistatic layer is provided, which can prevent static electricity from being generated between maintenance personnel and the vertical rod 401 and the stabilizing plate 402 during use, thereby preventing the fabric on the needle from catching fire, thereby increasing safety.

[0039] As a technical optimization solution of the utility model, a plurality of groups of circular grooves 6 are provided on the top of the ladder 5 , and the circular grooves 6 are used to prevent dust from accumulating on the ladder 5 .

[0040] In this embodiment, the circular groove 6 is provided to prevent dust on the soles of maintenance personnel from accumulating on the ladder 5. When the dust moves, it may float onto the fabric, thereby preventing the fabric from being contaminated.

[0041] As a technical optimization solution of the present invention, the limiting rod 305 is made of carbon fiber composite material, and the limiting rod 305 is used to prevent the screw barrel 303 from rotating along with the screw rod 302 .

[0042] In this embodiment, the limiting rod 305 is made of carbon fiber composite material. The carbon fiber composite material is an insulating material that can prevent the generation of static electricity. At the same time, the carbon fiber composite material also has a relatively high hardness, which can increase the service life of the limiting rod 305.

[0043] As a technical optimization solution of the present utility model, the ladder 5 is made of galvanized steel plate.

[0044] In this embodiment, by providing a ladder 5 made of a galvanized steel plate, since the surface of the galvanized steel plate has good conductivity, the generation of static electricity can be effectively prevented.

[0045] Working principle: when it is necessary to replace the needle on the needle plate 306, the maintenance personnel can reach the appropriate position by climbing the ladder 5. When the maintenance personnel replaces the needle, the coordinated use of the vertical rod 401 and the stabilizing plate 402 can effectively limit the position of the maintenance personnel, prevent the maintenance personnel from excessive movement and contact with the remaining needles, causing the maintenance personnel to be stabbed, thereby improving the safety when replacing the needle. Then, the large circular knitting machine body 1 is powered off to prevent the large circular knitting machine body 1 from accidentally starting, and then the motor 301 is started. The motor 301 drives the screw rod 302 to rotate. Because the screw rod 302 is threadedly connected to the screw barrel 303, the screw rod 302 rotates and drives the screw barrel 303 and the needle plate 306 to rise. Then the limiting rod 305 slides inside the limiting groove 304 to prevent the screw barrel 303 from rotating with the screw rod 302. When the needle plate 306 is raised to a suitable height, the maintenance personnel can replace the needle at the bottom of the needle plate 306. After the replacement is completed, the above steps can be reversed.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
