[0002] A circular knitting machine is an instrument used in the field of textile science and technology. It is mainly used to produce knitted fabrics, which are widely used in clothing, home textiles, and industrial fabrics, such as the production of T-shirts, polo shirts, shirts, underwear, and sportswear.

[0003] Circular knitting machines are used in the production of textiles. Existing circular knitting machines require the take-up roller to take up the finished fabric. However, the fabric is prone to shifting during take-up, which results in uneven fabric being taken up on the take-up roller, affecting the take-up effect. Utility Model Content

[0004] The purpose of this invention is to provide a circular knitting machine with a correction structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circular knitting machine with a correction structure, comprising: a support frame and a switching mechanism. A body is mounted on the top of the support frame, and a connecting frame is mounted on the bottom of the support frame. A take-up roller is movably connected to the inner side of the connecting frame via a rotating shaft. A tension roller a and a tension roller b are provided on the top of the take-up roller. A threaded rod b is movably connected to the inside of the connecting frame via a bearing. A limit block is threaded to one end of the threaded rod b. A switching mechanism is provided at one end of the threaded rod b. The switching mechanism includes a worm gear movably connected to the connecting frame via a bearing. A worm wheel is meshed with the outer side of the worm gear. A rectangular groove a is opened inside the worm gear, and the rectangular groove a is engaged with a rectangular block. Adjustment mechanisms are provided at both ends of the tension roller b.

[0006] Preferably, the two ends of the tension roller a are movably connected to the connecting frame via bearings, a V-groove is provided on one side of the limiting block, and two sets of sliding rods are fixedly connected to the other side of the limiting block.

[0007] Preferably, the outer side of the slide rod is slidably connected to the connecting frame, and the inside of the worm gear is slidably connected to a handle, one end of which is fixed to the rectangular block.

[0009] Preferably, the adjusting mechanism includes a bevel gear a fixed to the top of the connecting shaft, and a bevel gear b meshing with the outer side of the bevel gear a.

[0010] Preferably, a threaded rod a is fixedly connected to one side of the bevel gear b, one end of the threaded rod a is movably connected to the connecting frame via a bearing, and a connecting block is threadedly connected to the outer side of the threaded rod a.

[0011] Preferably, one side of the connecting block is movably connected to the tension roller b via a bearing, and the outer side of the connecting block is slidably connected to the connecting frame.

[0012] Compared with the prior art, the beneficial effects of the circular knitting machine with a correction structure described in this utility model are as follows: When winding the fabric, in order to prevent the fabric from shifting, the rectangular block at the top is rotated by turning the handle. At this time, the rectangular block will be in the rectangular groove a at the end of the worm. When rotating, it can also drive the worm to rotate, so that the worm meshes with the worm wheel. The worm wheel will rotate and drive the outer threaded rod b to rotate as well. The threaded rod b will engage with the limiting block through threaded transmission, thereby approaching the fabric.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 The present invention provides a circular knitting machine with a correction structure, comprising: a support 1 and a switching mechanism 7, wherein an organic body 2 is installed on the top of the support 1 and a connecting frame 3 is installed on the bottom of the support 1.

[0021] The inner side of the connecting frame 3 is movably connected to the take-up roller 4 via a rotating shaft. The top of the take-up roller 4 is provided with tension roller a5 and tension roller b6. The inside of the connecting frame 3 is movably connected to the threaded rod b9 via a bearing. One end of the threaded rod b9 is threadedly connected to the limit block 11. One end of the threaded rod b9 is provided with a switching mechanism 7. The switching mechanism 7 includes a worm gear 701 movably connected to the connecting frame 3 via a bearing. The outer side of the worm gear 701 is meshed with a worm wheel 10. The inside of the worm gear 701 is provided with a rectangular groove a704, and the rectangular groove a704 is engaged with the rectangular block 703. The two ends of the tension roller b6 are provided with adjustment mechanisms 8.

[0022] The tension roller a5 is movably connected to the connecting frame 3 via bearings at both ends. A V-groove is provided on one side of the limiting block 11, and two sets of sliding rods 12 are fixedly connected to the other side of the limiting block 11. The outer sides of the sliding rods 12 are slidably connected to the connecting frame 3. A handle 702 is slidably connected inside the worm gear 701, and one end of the handle 702 is fixed to the rectangular block 703. A connecting shaft 705 is provided at the top of the rectangular groove a704, and a rectangular groove b706 matching the rectangular block 703 is provided at the bottom of the connecting shaft 705. The adjusting mechanism 8 includes a bevel gear a801 fixed to the top of the connecting shaft 705, and the outer side of the bevel gear a801 is meshed with... A bevel gear b802; a threaded rod a803 is fixedly connected to one side of the bevel gear b802, one end of the threaded rod a803 is movably connected to the connecting frame 3 through a bearing, and a connecting block 804 is threadedly connected to the outer side of the threaded rod a803; one side of the connecting block 804 is movably connected to the tension roller b6 through a bearing, and the outer side of the connecting block 804 is slidably connected to the connecting frame 3. The connecting frame 3 has a sliding groove that matches the connecting block 804. The connecting block 804 and the connecting frame 3 form a sliding structure, the threaded rod a803 and the connecting block 804 form a threaded transmission structure, and the bevel gear a801 and the bevel gear b802 form a meshing transmission structure.

[0023] In practical implementation, when the circular knitting machine with the correction structure is winding the fabric, in order to prevent the fabric from shifting, the handle 702 is turned to drive the top rectangular block 703 to rotate. At this time, the rectangular block 703 will be in the rectangular groove a704 at the end of the worm 701. When rotating, it can drive the worm 701 to rotate as well, so that the worm 701 meshes with the worm wheel 10. The worm wheel 10 will rotate and drive the outer threaded rod b9 to rotate as well. The threaded rod b9 will engage with the limiting block 11 through threaded transmission, thereby getting closer to the fabric. By adjusting the position of the two sets of limiting blocks 11, the passing fabric can be limited, thereby preventing the fabric from shifting during the winding process.

[0024] When the position of the tension roller b6 needs to be adjusted to change the fabric tension, the upward movement of the handle 702 drives the rectangular block 703 to move into the rectangular groove b706 inside the connecting shaft 705, disengaging it from the rectangular groove a704. At this time, turning the handle 702 can drive the connecting shaft 705 to rotate. The connecting shaft 705 can drive the top bevel gear a801 to mesh with the bevel gear b802, thereby driving the threaded rod a803 on one side to perform threaded transmission with the connecting block 804, causing the tension roller b6 on one side of the connecting block 804 to also move, thus tensioning the fabric. In this way, the above operation can facilitate the correction of the fabric being wound up in the circular knitting machine.

[0025] In summary: When using a circular knitting machine with a correction structure, the yarn is first fed into the machine body 2, and then woven by the knitting mechanism in the machine body 2. The woven fabric is then wound up by the take-up roller 4.
