Abstract
Description
Technical Field
[0001] This utility model relates to the field of glue needle processing technology, specifically a cutting assembly and its roll glue needle head. Background Technology
[0002] The roll-to-gluing needle machine head is a key component in the textile labeling process, responsible for handling the glue needles. It undertakes a series of important operations such as feeding, cutting, and coordinating with subsequent labeling. Its performance directly affects the overall efficiency and quality of roll-to-gluing needle feeding, cutting, and labeling.
[0003] Existing glue needle cutting machines typically use a single cutting blade inside the machine head to cut the glue needles. However, this single cutting blade design is not ideal in practical applications, often resulting in incomplete cutting of the glue needles and residual glue needles. This not only prevents the machine head from properly feeding glue needles but also leads to substandard quality of the labeled products, increasing the rework rate in the production process.
[0004] The main reason for incomplete cutting of the rubber needle is that the single-blade cutter applies force to a relatively singular point during the cutting process. When the rubber needle is made of a hard material or has a slightly larger diameter, the single-blade cutter cannot provide a sufficiently uniform and strong shearing force, resulting in the rubber needle not being completely cut off in one go. Furthermore, the single-blade cutter is prone to wear after prolonged use, further reducing the accuracy and force of the cutting, making the problem of incomplete cutting of the rubber needle even more prominent. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0032] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0033] This utility model discloses a cutting assembly and a winding machine head, according to the attached... Figure 1-5 As shown, it includes a cutter assembly 1, which includes a fixed blade 11, a moving blade 12, and a rocker arm 13;
[0034] The fixed blade 11 consists of a left blade and a right blade, with the right blade being thicker than the left blade. The moving blade 12 is positioned below the fixed blade 11, and a slit is provided inside the moving blade 12. Glue needles are installed inside both the fixed blade 11 and the moving blade 12. The swing rod 13 is positioned on one side of the moving blade 12 and is driven by the moving blade 12. The swing rod 13 drives the moving blade 12 to perform a horizontal reciprocating motion, thereby cooperating with the fixed blade 11 to cut the glue needles.
[0035] The roll forming head includes a frame 2 and a glue needle feed groove 3; a cutter assembly 1 is mounted on the frame 2; the glue needle feed groove 3 is located inside the frame 2. A drive unit 4 is located on the top of the frame 2, including a cylinder 41 and a push slider 42; the cylinder 41 is fixedly mounted on the top of the frame 2; the push slider 42 is slidably connected inside the frame 2, and the output shaft of the cylinder 41 is fixedly mounted to the push slider 42. The drive unit 4 also includes a ejector pin 43 and a guide wheel 44; the ejector pin 43 is fixedly mounted on the front end of the push slider 42; the guide wheel 44 is located at the rear end of the push slider 42. A guide groove 14 is provided on the back of the swing arm 13, and the guide wheel 44 is slidably connected inside the guide groove 14; the middle end of the swing arm 13 is rotatably connected to the frame 2. The bottom end of the swing arm 13 is provided with a positioning port 15. A locking block 16 is rotatably connected to one side of the moving blade 12. The locking block 16 is movably locked inside the positioning port 15. The bottom end of the frame 2 is provided with a cutting blade slide groove. The moving blade 12 is slidably connected inside the cutting blade slide groove. A nailing needle 6 is fixedly mounted at the bottom of the frame 2.
[0036] In this embodiment, after the glue needle enters from the glue needle feed groove 3, it is conveyed between the fixed blade 11 and the moving blade 12. The cylinder 41 at the top of the frame 2 is activated, and its output shaft drives the pusher slider 42 to slide inside the frame 2. The pusher pin 43 at the front end of the pusher slider 42 pushes and positions the glue needle to prevent displacement during the cutting process. At the same time, the guide wheel 44 at the rear end of the pusher slider 42 slides in the guide groove 14 on the back of the swing arm 13. Since the middle end of the swing arm 13 is rotatably connected to the frame 2, the sliding of the guide wheel 44 will drive the swing arm 13 to rotate around its middle end. When the swing arm 13 rotates, the positioning port 15 at its bottom end, through cooperation with the locking block 16 on one side of the moving blade 12, drives the moving blade 12 to make horizontal reciprocating motion in the cutting groove at the bottom of the frame 2. The moving blade 12 and the fixed blade 11 work together to cut the glue needle like scissors, ultimately severing it. At the same time, the nailing needle 6 at the bottom of the frame 2 performs the nailing operation. The fixed blade 11 consists of a left blade and a right blade, with the right blade being thicker than the left blade. This design allows for more suitable cutting force based on different parts of the glue needle and the force applied during the cutting process. Especially for thicker or harder glue needles, the thicker blade of the right blade can apply stronger cutting force, while the thinner blade of the left blade ensures the accuracy of the cutting, avoiding glue needle residue or incomplete breakage due to uneven force.
[0037] According to the appendix Figure 1 ,6 As shown, further, it includes a cutter assembly 1, which includes a fixed blade 11, a moving blade 12, and a rocker arm 13;
[0038] The fixed blade 11 consists of a left blade and a right blade, with the right blade being thicker than the left blade. The moving blade 12 is positioned below the fixed blade 11, and a slit is provided inside the moving blade 12. Glue needles are installed inside both the fixed blade 11 and the moving blade 12. The swing rod 13 is positioned on one side of the moving blade 12 and is driven by the moving blade 12. The swing rod 13 drives the moving blade 12 to perform a horizontal reciprocating motion, thereby cooperating with the fixed blade 11 to cut the glue needles.
[0039] The frame 2 is equipped with a glue needle pushing assembly 5, which includes a push needle component 51 and a push hook 52. The end of the push hook 52 is rotatably connected to the push needle component 51, and a lever is fixedly installed on the top of the push hook 52. The glue needle pushing assembly 5 also includes a slide groove 53 and a spring 54. The slide groove 53 is formed inside the push needle component 51. One end of the spring 54 is fixedly assembled with the push hook 52, and the other end of the spring 54 is fixedly assembled with the push needle component 51.
[0040] In this embodiment, the pusher 51 slides downward when pushed by the pusher slider 42, thereby pushing the glue needle. The glue needle pushing assembly 5 can effectively prevent the roll of glue needle that has not yet been cut from retracting. When it is necessary to separate the glue needle stuck in the glue needle pushing assembly 5, the glue needle can be separated simply by manually opening the pry block on the push hook 52.
