DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to further explain the technical solution of the utility model, the following is elaborated in detail through specific embodiments.

[0024] Please refer to Figure 1 and Figure 2 , the utility model provides a circular knitting machine with high processing efficiency, including a circular knitting machine main body 1, a controller 2, a safety door 3 and a supporting structure 4. A controller 2 is arranged on one side of the circular knitting machine main body 1, and a safety door 3 is installed on the bottom side of the outer surface of the circular knitting machine main body 1. The supporting structure 4 is firmly fixed to the bottom side of the circular knitting machine main body 1, so as to facilitate the movement through the supporting structure 4, and thus it is convenient to move out of the working environment for overhauling and maintaining, improving the processing efficiency of the circular knitting machine to a certain extent.

[0025] Please refer toFigure 2 , Figure 3 and Figure 4 , the present utility model provides a circular knitting machine with high processing efficiency. The supporting structure 4 includes a cylinder base 41 whose top side is fastened to the main body 1 of the circular knitting machine, a rotating block 42 rotatably connected to the upper part of one side of the cylinder base 41, a rotating rod 43 fixed to the middle side of the rear part of the rotating block 42, a driving gear 44 wrapped and fixed on the outer surface of the rotating rod 43, a driven gear 45 meshing with the side part of the driving gear 44, a positioning frame 46 rotatably connected to the middle side of the top of the driven gear 45, a threaded rod 47 connected to the middle side of the bottom of the driven gear 45, an internal thread sleeve 48 threadedly connected to the outer surface of the threaded rod 47, and a pad frame assembly 49 fastened to the bottom side of the internal thread sleeve 48. The top side of the positioning frame 46 is fixed to the cylinder base 41. There are two pad frame assemblies 49, and the middle sides of the bottoms of the two pad frame assemblies 49 are both connected to the internal thread sleeve 48, so as to facilitate the movement adjustment of the height position of the pad frame assembly 49 through the internal thread sleeve 48, so that the pad frame assembly 49 supports on the ground.

[0026] The inside of the cylinder base 41 is a hollow structure, and there is a through hole on one side of the cylinder base 41. One end of the rotating rod 43 passes through and rotates inside the through hole, and the other end is rotatably connected to the cylinder base 41 to ensure the stability of the rotation of the rotating rod 43. There are two driving gears 44, and they are respectively located on both sides of the rotating rod 43. Columns are provided on both sides of the bottom of the positioning frame 46, and the two driving gears 44 are respectively rotatably connected to the two columns, which is convenient for the two driving gears 44 to rotate synchronously. There are two groups of driven gears 45, threaded rods 47 and internal thread sleeves 48, and they are symmetrically arranged in the middle of the cylinder base 41, and the height position of the internal thread sleeve 48 can be adjusted on both sides at the same time to ensure the stability of the support.

[0027] Please refer to Figure 3 and Figure 5 , the present utility model provides a circular knitting machine with high processing efficiency. The pad frame assembly 49 includes a first sleeve 491 whose top is fixed to the positioning frame 46, a sliding frame 492 made of aluminum alloy and slidably connected to the middle side inside the first sleeve 491, a second sleeve 493 slidably connected to the other side of the top of the sliding frame 492, and a first roller 494 and a second roller 495 respectively arranged on the left and right sides of the bottom of the sliding frame 492, so as to facilitate the movement of the position through the contact of the two groups of rollers 494 with the ground. The top side of the second sleeve 493 is fixed to the positioning frame 46. A through groove is provided on the bottom plate of the cylinder base 41, and the sliding frame 492 is arranged through the inside of the through groove, which is convenient for the sliding frame 492 to make a longitudinal shift, so as to ensure that the two groups of rollers 494 are in contact with the ground after the sliding frame 492 moves downward.

[0028] The working principle is as follows:

[0029] First, the user can rotate the rotary block 42 to drive the rotary rod 43 to drive the two driving gears 44 to rotate on the positioning frame 46. The driving gears 44 cooperate with the two groups of driven gears 44 to make the threaded rod 47 rotate inside the internal thread sleeve 48. Thus, the thread sleeve 48 drives the two groups of sliding frames 492 to longitudinally displace inside the two groups of first sleeves 491 and second sleeves 493 respectively, so that the sliding frames 492 drive the first rollers 494 and the second rollers 495 to contact the ground to jack up the circular knitting machine main body 1. Then, under the support of the two groups of rollers, the circular knitting machine main body 1 is moved to the position where it needs to be used. Then, rotate the rotary block 42 in the reverse direction to make the sliding frames 492 drive the first rollers 494 and the second rollers 495 to reset, thus ensuring the stability of the circular knitting machine main body 1 during the working process;

[0030] Secondly, thread the knitting thread into the circular knitting machine main body 1 for production preparation. When the circular knitting machine main body 1 needs to be overhauled and maintained, the rotary block 42 can be rotated again to make the two groups of first rollers 494 and the second rollers 495 contact the ground, so as to move the circular knitting machine main body 1 out of the working environment for processing, avoiding the space on the workbench being too narrow and thus affecting the efficiency of overhaul and maintenance.

[0031] The utility model provides a circular knitting machine with high processing efficiency. By optimizing the support structure 4 at the bottom of the circular knitting machine main body 1, the inside of the cylinder base 41 is a hollow structure, and the rotary rod 43 passes through and rotates inside the cylinder base 41. Two driving gears 44 are arranged on the rotary rod 43, and the driving gears 44 are meshed with the driven gears 45 rotating at the bottom side of the positioning frame 46. When the driving gears 44 rotate, the two groups of threaded rods 47 and the two groups of internal thread sleeves 48 cooperate with each other through the cooperation with the driven gears 45. Thus, the thread sleeve 48 drives the two groups of sliding frames 492 to make the two groups of first rollers 494 and the second rollers 495 contact the ground to jack up the circular knitting machine main body 1, so as to facilitate moving the circular knitting machine main body 1 to the position where it needs to be used, and moving the circular knitting machine main body 1 out of the working environment during overhaul and maintenance, avoiding the space on the workbench being too narrow and thus affecting the efficiency of overhaul and maintenance.

[0032] The above are only the preferred examples of the utility model and are not used to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
