Description

Technical Field

[0001] This utility model relates to the field of knitting needle processing technology, specifically to a burr removal device for knitting needle processing. Background Technology

[0002] During knitting, the knitting needles are responsible for bending the yarn into loops. Through the continuous movement of the needles, the yarn is hooked, pulled, and released, forming a continuous loop structure. As the needles continue to move, the loops interlock, constructing the overall structure of the knitted fabric. During needle manufacturing, wear on the cutting tools during processing dulls the cutting surface, increasing cutting force and easily causing burrs on the machined surface. Furthermore, if the cutting tools themselves are not sharp enough, this also increases cutting force and leads to burr formation. The presence of burrs affects the surface smoothness and precision of the knitting needles, as well as their wear resistance and lifespan. Therefore, burrs need to be removed. However, many traditional devices for deburring knitting needles lack sufficient precision in their clamps, resulting in unsatisfactory deburring effects, and even unstable needle fixation, leading to uneven deburring or even damage to the needles.

The device is equipped with a clamping head 310, which has a diameter of 2mm and can accommodate most sizes of knitting needles except for extra-small sizes. It provides sufficient clamping force to stably hold the knitting needles and prevent them from sliding or shifting during processing. Three second fixing rods 34 are provided, and each of the three second fixing rods 34 is rotatably connected to a small gear 311. The three small gears 311 mesh with adjacent racks 39 and gear rings 37. The output end of the second motor 35 is fixedly connected to a large gear 312, which meshes with the gear ring 37.

[0029] The working principle of this utility model is as follows: First, the knitting needle is held in the middle position of the three clamping heads 310. The second motor 35 is started, causing the large gear 312 at the output end of the second motor 35 to rotate. As the large gear 312 rotates, it drives the gear ring 37 meshing with it to rotate in the inner wall of the connecting plate 36. As the gear ring 37 rotates, it drives the three small gears 311 to rotate together. When the three small gears 311 rotate, they respectively drive their adjacent racks 39 to slide in the inner wall of their respective adjacent sliding holes 38 towards the opposite side, so that the three clamping heads 310 move simultaneously in three directions. The outer surface of the knitting needle is evenly clamped and tightly held. Then, the grinding machine body 43 is started to rotate and work. Next, the two electric telescopic rods 41 are started, which drive the support plate 42 and the grinding machine body 43 on it to move upward together, so that the grinding machine body 43 rises to the needle body and contacts the needle body to grind and remove burrs. Finally, the first motor 31 is started, which makes the connecting plate 32 at its output end and all the structures on it rotate, so that the knitting needle is driven to rotate continuously, and the grinding machine body 43 evenly grinds and removes burrs from the outer surface of the needle body.
