Description

Technical Field

[0001] This application relates to the field of yarn guiding equipment technology, and more specifically, to an elastic yarn guiding sheet device. Background Technology

[0002] In the field of textile machinery, yarn guides are key components used to guide the movement of yarn. They are used to control the movement path of the yarn or change the direction of the yarn movement. During the yarn guiding process, the yarn guides need to ensure that the yarn can be stably transferred from one process to another, while avoiding the yarn from deviating or tangling during the transfer process.

[0003] Traditional yarn guides are usually made of rigid materials. When the yarn is subjected to a large traction force, the rigid structure of the yarn guide cannot provide sufficient cushioning, causing the yarn to stretch and deform or break due to excessive traction force. This affects the quality of yarn guidance, and requires frequent shutdowns of textile equipment for maintenance and reconnection of broken yarns, which seriously restricts production efficiency.

[0004] Therefore, we propose an elastic yarn guide device to solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to provide an elastic yarn guide device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an elastic yarn guide device, comprising a mounting ring, wherein the mounting ring has an inner cavity axially penetrating both ends of the mounting ring along its central axis, an opening is provided on the side wall of the inner cavity, an elastic plate is connected to the side of one end of the opening, a yarn threading plate is connected to the end of the elastic plate, a reverse bow plate approaching the elastic plate is connected to the side of the other end of the opening, and a guide plate is fixedly connected to the top end face of the elastic plate.

[0007] Preferably, the elastic plate includes a concave plate and a convex plate, the concave plate and the convex plate are arranged in multiple sets and alternately arranged along the same horizontal end face, and the adjacent ends of the concave plate and the convex plate are connected to each other.

[0008] Preferably, the guide plate has multiple sets, and the multiple sets of guide plates are equidistantly arranged along the axis of the mounting ring and are all fixedly connected to the elastic plate.

[0009] Preferably, a guide groove is formed between two adjacent guide plates.

[0010] Preferably, the yarn threading plate is provided with a plurality of yarn threading holes at equal intervals, and the yarn threading holes are provided in a one-to-one correspondence with the guide grooves.

[0011] Preferably, the top and bottom end faces of the threading hole have arc angles that transition and connect with the top and bottom end faces of the threading plate, respectively.

[0012] Preferably, a fixing seat is installed at the bottom end of the mounting ring near the reverse bow plate. The fixing seat has a threaded hole on its central axis that passes through the fixing seat and communicates with the inner cavity of the mounting ring. The fixing seat is connected to a fixing bolt through the threaded hole.

[0013] The elastic yarn guide device provided by this utility model has the following advantages compared with the prior art: By setting an elastic plate on the mounting ring, the elastic plate can release the force when the yarn traction force is too large during the yarn guiding process, thereby avoiding the yarn being excessively stretched and breaking, protecting the yarn quality, avoiding frequent machine downtime for maintenance, and improving the yarn guiding efficiency.

[0014] This invention provides multiple sets of guide plates on the top of an elastic plate, with guide grooves between adjacent guide plates. A yarn threading plate is connected to the front end of the elastic plate, and the yarn threading plate has yarn threading holes that correspond one-to-one with the guide grooves. This allows multiple yarns to be guided simultaneously, while also constraining the range of motion between the yarns, preventing tangling during the yarn guiding process, and improving the yarn guiding accuracy.

[0023] Examples, such as Figures 1 to 5As shown, an elastic yarn guide device includes a mounting ring 1. The mounting ring 1 has an inner cavity 11 axially penetrating both ends of the mounting ring 1 along its central axis. An opening 12 is provided on the side wall of the inner cavity 11. An elastic plate 2 is connected to the side of one end of the opening 12, and a yarn-passing plate 4 is connected to the end of the elastic plate 2. A reverse bow plate 13 approaching the elastic plate 2 is connected to the side of the other end of the opening 12. A guide plate 3 is fixedly connected to the top end face of the elastic plate 2. In use, the side end of the mounting ring 1 has an opening 12, through which the mounting ring 1 is fitted onto the yarn guide plate. On the outer periphery of the fixing rod used to fix the yarn guide plate on the textile equipment, the inner cavity 11 of the mounting ring 1 is connected to the outer periphery of the fixing rod, so that the yarn threading plate 4 is installed on the fixing rod. The yarn threading plate 4 is used to guide the yarn through. An elastic plate 2 is provided between the yarn threading plate 4 and the mounting ring 1. During the yarn guiding process, the yarn contacts the elastic plate 2. When the traction force on the yarn is too large, the yarn puts pressure on the elastic plate 2, causing the elastic plate 2 to undergo elastic deformation to relieve the force, thereby avoiding the yarn from being stretched or broken due to excessive traction force.

[0024] Furthermore, the elastic plate 2 includes a concave plate 21 and a convex plate 22. The concave plate 21 and the convex plate 22 are arranged in multiple sets and alternately arranged along the same horizontal end face. The adjacent ends of the concave plate and the convex plate 22 are connected to each other. In use, the elastic plate 2 is composed of multiple concave plates 21 and convex plates 22 alternately connected. During the yarn guiding process, the yarn slides and connects with the top end face of the convex plate 22 to enhance the bending resistance of the elastic plate 2 and make the elastic plate 2 have better elastic recovery ability.

[0025] Furthermore, the guide plate 3 has multiple sets, and the multiple sets of guide plates 3 are equidistantly arranged along the axis of the mounting ring 1 and are all fixedly connected to the elastic plate 2 to guide the yarn's guiding movement path.

[0026] Furthermore, a guide groove 31 is formed between two adjacent guide plates 3. In use, it is used to constrain the movement of the yarn in the guide groove 31 and prevent the yarn from deviating from the guide plate.

[0027] Furthermore, the yarn threading plate 4 is provided with multiple yarn threading holes 41 at equal intervals. The yarn threading holes 41 are arranged one-to-one with the guide grooves 31. In use, the direction of yarn movement is changed by the yarn threading holes 41, so that the yarn passing through the yarn threading hole 41 is connected to the knitting needle of the textile equipment for weaving. The multiple yarn threading holes 41 are used to independently guide multiple yarns to connect with the textile equipment. The multiple yarns are separated by multiple guide plates 3 and are arranged in the guide grooves 31 corresponding to the yarn threading holes to avoid the multiple yarns from getting tangled during the yarn guiding process.

[0028] Furthermore, the top and bottom end faces of the threading hole 41 have arc angles 42 that transition to the top and bottom end faces of the threading plate 4, respectively. In use, these arc angles are used to reduce friction between the yarn and the threading plate 4 and to protect the yarn from damage.

[0029] Furthermore, a fixing seat 5 is installed at one end of the mounting ring 1 near the bottom of the reverse bow plate 13. A threaded hole 51 is provided on the central axis of the fixing seat 5, penetrating the fixing seat 5 and connecting to the inner cavity 11 of the mounting ring 1. A fixing bolt 6 is connected to the fixing seat 5 through the threaded hole 51. In use, by tightening the fixing bolt 6, the bolt body of the fixing bolt 6 engages with the threaded hole 51, causing one end of the fixing bolt 6 to spiral along the threaded hole 51, gradually passing through the fixing seat 5 and abutting against the end face of the fixing rod in the inner cavity 11 of the mounting ring 1. This fixes the mounting ring 1 onto the fixing rod, thus securing the mounting ring 1. During the yarn guiding process, the mounting ring 1 is securely connected to the fixing rod. One end of the opening 12 is provided with a reverse bow plate 13, which gives the opening 12 a certain elastic expansion capacity. This makes it easier to expand the opening 12 by simultaneously pulling the reverse bow plates 13 and the elastic plate 2 on both sides of the opening 12. This makes it easier to fit the mounting ring 1 onto the fixing rod through the opening 12. After installation, the reverse bow plate 13 and the elastic plate 2 are reset under the action of the ring structure of the mounting ring 1, so that the opening 12 returns to its original size, which is smaller than the diameter of the fixing rod, thereby preventing the mounting ring 1 from falling off the fixing rod.

[0030] The working principle of this utility model is as follows: The mounting ring 1 has an inner cavity 11, and one side of the inner cavity 11 has an opening 12. One side of the opening 12 is connected to an elastic plate 2, and the end of the elastic plate 2 is connected to a yarn-threading plate 4. During the yarn guiding process, the yarn is pulled from one end of the mounting ring 1 through the elastic plate 2 and then through the yarn-threading plate 4 to connect with the knitting needle of the textile equipment. During the yarn guiding process, the yarn slides and connects with the elastic yarn guiding plate device under the action of traction force. When the yarn traction force is too large, the elastic plate 2 is subjected to the downward pulling force of the yarn on its surface. The elastic plate 2 deforms under the force to relieve the force and prevent the yarn from being pulled and deformed. The elastic plate 2 is composed of multiple sets of concave plates 21 and convex plates 22 connected alternately to give it good elasticity. The top of the elastic plate 2 has multiple sets of guide plates 3, which are equidistantly arranged along the axis of the mounting ring 1. Adjacent guide plates 3 form guide grooves 31 for constraining the yarn. The yarn-threading plate 4 has multiple yarn-threading holes 41 corresponding to the guide grooves 31 for... Multiple yarns are guided independently. The edge of the yarn-threading hole 41 has a rounded corner 42 to reduce friction between the yarn-threading hole 41 and the yarn. The opposite side of the opening 12 relative to the elastic plate 2 is connected to a reverse bow plate 13, which can be pried with a tool to move it away from the elastic plate 2, thereby expanding the opening 12 and making it easier to fit the mounting ring 1 onto the fixing rod. Due to its reverse bow structure opposite to the ring orientation of the mounting ring 1, the reverse bow plate 13 is reset by the ring tension of the mounting ring 1 and the resistance of its own bow structure after the force of prying the reverse bow plate 13 disappears, so that the size of the opening 12 returns to its original size, thereby preventing the mounting ring 1 from falling off the fixing rod. The bottom of the mounting ring 1 has a fixing seat 5, which is connected to a fixing bolt 6 through a threaded hole 51. Tightening the fixing bolt 6 can make one end of the mounting ring 1 pass through the mounting ring 1 and abut against the end face of the fixing rod, thereby fixing the mounting position of the mounting ring 1 on the fixing rod and preventing the rotation of the mounting ring 1 from affecting the yarn guide.

[0031] The above-described specific embodiments are merely preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
