Description

Technical Field

[0001] This utility model relates to the field of yarn rewinding frame technology, specifically a yarn rewinding frame for a circular knitting machine. Background Technology

[0002] Circular knitting machines, also known as circular weft knitting machines (or circular weft knitting machines), have seen rapid development due to their numerous loop-forming systems (commonly referred to as yarn feed paths or loop formation paths, or simply paths), high speed, high output, rapid pattern changes, good fabric quality, fewer processing steps, and strong product adaptability.

[0003] Currently, some existing circular knitting machines have relatively fixed roller dimensions and relatively smooth surfaces for inserting yarn rolls. When the yarn is quickly peeled off from the surface of the yarn roll, the yarn may get stuck, causing the yarn to pull the yarn roll off the roller surface, reducing production efficiency. At the same time, it has poor adaptability to yarn rolls of different diameters, making it relatively inconvenient to use. Therefore, we propose a yarn rewinding frame for circular knitting machines to solve or improve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a yarn rewinding frame for a circular knitting machine, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: it includes a mounting frame, a support frame that is rotatably mounted on the surface of the mounting frame via a rotating shaft, a support rod that is fixed to the top of the support frame, a limiting rod that is inserted into the inside of the support rod, a support plate that is fixed to the top of the limiting rod, a spring that is sleeved on the surface of the limiting rod, and an adjustment component that is set on the surface of the support plate.

[0006] Furthermore, the adjustment assembly includes a mounting bracket fixed to the surface of the support plate, a threaded rod inserted through the mounting bracket into the support rod and threadedly connected to the support rod, and an adjustment knob fixed to the top of the threaded rod.

[0007] Furthermore, a top plate is fixed to the top of the support rod, and the top plate is located on one side of the top of the support plate.

[0008] Furthermore, a guide wire ring is rotatably mounted on the top of the mounting bracket via a pivot, and the guide wire ring is located on one side diagonally above the top of the support plate.

[0009] Furthermore, the surface of the support plate is fixed with annular rubber protrusions.

[0010] Furthermore, a limit plate is fixed to one end of the limit rod.

[0011] Compared with the prior art, this utility model has the following advantages: By setting springs, support plates, and adjustment components, the friction between the support plate surface and the silk roll can be increased by the ring-shaped rubber protrusions on the support plate surface when the silk roll is inserted into the support plate surface. This reduces or avoids the possibility of the silk thread getting stuck when it is quickly peeled off from the surface of the silk roll, causing the silk thread to pull the silk roll off the support plate surface, thereby indirectly improving production efficiency. The position of the two sets of support plates can be adjusted by the adjustment components, thereby adjusting the distance between the two sets of support plates, thus improving the adaptability of the support plates to silk rolls of different sizes and specifications, and making it relatively convenient to use.

[0018] 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.

[0019] Please see Figure 1-5The system includes a mounting frame 1, a support frame 2 rotatably mounted on the surface of the mounting frame 1 via a rotating shaft, a support rod 10 fixed to the top of the support frame 2, a limiting rod 9 inserted inside the support rod 10, and a limiting plate fixed to one end of the limiting rod 9 to restrict the position of the limiting rod 9 and prevent it from detaching from the support rod 10. Several sets of limiting rods 9 are symmetrically inserted on the surface of the support rod 10. A support plate 5 is fixed to the top of the limiting rods 9, and two sets of the support plate 5 are symmetrically fixed to the top of the several sets of limiting rods 9. Annular rubber protrusions are fixed to the surface of the support plate 5. These annular rubber protrusions can contact the inner surface of the wire roll when it is inserted into the surface of the support plate 5, increasing the friction between the wire roll and the annular rubber protrusions. A top plate 4 is fixed to the top of the support rod 10, located on one side of the top of the support plate 5. The top plate 4 can be used to control the position of the wire roll inserted into the support plate 10. The minimum diameter of the wire roll on the surface of the support plate 5 is limited to prevent small wire rolls from being difficult to remove after being placed on the surface of the support plate 5. The spring 8 is placed on the surface of the limiting rod 9. The number of springs 8 is the same as the number of limiting rods 9. One end of the spring 8 is fixed to the inner surface of the support rod 10, and the other end is in contact with the surface of the support plate 5. When the support plate 5 moves, it will squeeze the spring 8 and cause the spring 8 to deform. When there is no external force interference, the spring 8 will push the support plate 5 to move. At the same time, the spring 8 can apply a certain force to the surface of the support plate 5, thereby ensuring that the surface of the support plate 5 is always in close contact with the inner surface of the wire roll when the wire roll is placed on the surface. The top of the mounting bracket 1 is rotatably mounted with a wire guide ring 3 through a rotating shaft. The wire guide ring 3 is located on one side diagonally above the top of the support plate 5. The adjustment components are set on the surface of the support plate 5. The number of adjustment components is the same as the number of support plates 5.

[0020] The adjustment assembly includes a fixing frame 7 fixed to the surface of the support plate 5, a threaded rod 11 inserted through the fixing frame 7 and threadedly connected to the support rod 10, and an adjustment knob 6 fixed to the top of the threaded rod 11. The surface of the adjustment knob 6 is in contact with the surface of the fixing frame 7. When the adjustment knob 6 is rotated, it will drive the fixed threaded rod 11 to rotate. When the threaded rod 11 rotates, it will move itself through the threaded support rod 10. When the threaded rod 11 moves, it will drive the fixed adjustment knob 6 to move, thereby causing the adjustment knob 6 to drive the fixed frame 7 to move. When the fixed frame 7 moves, it will drive the fixed support plate 5 to move, causing the position of the support plate 5 to change.

[0021] Working principle: When the yarn rewinding frame is needed, the yarn roll is first placed on the surface of the support plate 5, and then the yarn is pulled out from the surface of the yarn roll and passed through the inside of the guide ring 3 to connect to the inside of the circular knitting machine, thus completing the installation of the yarn roll. At this time, the ring-shaped rubber protrusion on the surface of the support plate 5 can increase the friction between the surface of the support plate 5 and the yarn roll, thereby reducing or avoiding the possibility of the yarn getting stuck when it is quickly peeled off from the surface of the yarn roll, causing the yarn roll to fall off the surface of the support plate 5, thus indirectly improving production efficiency. At the same time, when it is necessary to install yarn rolls of different sizes and specifications, the adjustment knob 6 can be turned to drive the threaded rod 11 to rotate, thereby causing the threaded rod 11 to move the adjustment knob 6 and the adjustment knob 6 to move the fixing frame 7 and the support plate 5, thereby adjusting the position of the two sets of support plates 5 and changing the distance between the two sets of support plates 5. This improves the adaptability of the support plate 5 to yarn rolls of different sizes and specifications, making it relatively convenient to use.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
