Description

Technical Field

[0001] This utility model belongs to the field of yarn limiting protection technology, and particularly relates to a yarn limiting protection structure for a roving frame. Background Technology

[0002] Yarn limiting protection refers to the use of mechanical, electronic, or structural devices to limit and protect the position, tension, and range of motion of yarn during textile processing, winding, transportation, or use, in order to prevent yarn from shifting, loosening, tangling, breaking, or exceeding the safe operating range, thereby ensuring the safety of production equipment and improving product quality and efficiency.

[0003] Currently, the existing yarn limiting protection structure of roving frames typically requires multiple limiting wheels to guide the yarn through from above and below the limiting wheels in actual use. The limiting wheels can restrict the position of the yarn and ensure stable yarn transmission. However, since the existing yarn limiting protection structure does not have an auxiliary yarn threading function, the operator needs to manually guide the yarn for threading, which is time-consuming and labor-intensive. In addition, the spacing between adjacent components inside the limiting protection structure is small, leaving limited space for the operator's hands, which in turn affects the threading efficiency.

[0004] To address this issue, we propose a yarn limiting protection structure for a roving frame. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing technologies do not have the function of assisting in threading, and to propose a yarn limiting and protection structure for a roving frame.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A yarn limiting protection structure for a roving frame includes a mounting frame. A plurality of support columns are fixedly connected to the inner wall of the mounting frame. A limiting wheel body is rotatably connected to the outer surface of each support column. Two curved grooves are formed on the outer surface of the mounting frame. A guide post is slidably connected to the inner wall of the two curved grooves. A push plate is slidably connected to the outer surface of the guide post, and the outer surface of the push plate is slidably connected to the inner wall of the mounting frame. A stabilizing block is fixedly connected to the end of the guide post near the push plate, and the outer surface of the stabilizing block is slidably connected to the inner wall of the push plate. A screw is threadedly connected to the inner wall of the push plate. A pressing disc is slidably connected to the inner wall of the guide post. A pull column is fixedly connected to the outer surface of the pressing disc, and the outer surface of the pull column is slidably connected to the inner wall of the guide post. A strong spring is fixedly connected to the side of the pressing disc near the pull column, and the end of the strong spring away from the pressing disc is fixedly connected to the inner wall of the guide post.

[0007] Preferably, a plurality of positioning blocks are fixedly connected to the outer surface of the mounting frame, and each positioning block has a positioning hole on its upper surface.

[0008] Preferably, the upper surface of the mounting frame is fixedly connected with a plurality of fixing blocks, and each fixing block has a pull ring rotatably connected to its inner wall.

[0009] Preferably, both ends of the lead post are fixedly connected to retaining rings, and the sides of the two retaining rings that are close to each other are in contact with the outer surface of the mounting frame.

[0010] Preferably, each of the support columns is fixedly connected to both ends with a reinforcing ring, and the side of each set of reinforcing rings that is far apart from each other is fixedly connected to the inner wall of the mounting frame.

[0011] Preferably, both ends of the screw are rotatably connected to support blocks, and the side of each support block near the mounting frame is fixedly connected to the side of the mounting frame near the screw.

[0012] Preferably, a rotating block is fixedly connected to the left end of the screw, and the outer surface of the rotating block is provided with several anti-slip grooves.

[0013] Preferably, a pull head is fixedly connected to the end of the pull post away from the lead post, and the side of the pull head near the pull post is in contact with the side of the lead post away from the mounting frame.

[0014] In summary, the technical effects and advantages of this utility model are as follows: 1. By setting a screw, rotating the screw can drive the push plate to move. While the push plate moves, it can push the internal lead post to move. During the movement of the lead post, it can slide along the curved groove. The lead post can move flexibly along the trajectory of the curved groove, easily driving the yarn close to each limit wheel body. With the cooperation of the curved groove, it can quickly pass through the limit wheel body from above and below, thereby greatly improving the threading efficiency. 2. By setting up a squeezing plate, pulling the pull column drives the squeezing plate to move to one side and squeezes and compresses the strong spring, which can open up the space inside the lead post, insert the lead end of the yarn, and squeeze and fix the yarn by the pressure of the strong spring. This makes it easier for the lead post to move and drive the yarn to move when threading, which is convenient for threading work. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-5 A yarn limiting protection structure for a roving frame includes a mounting frame 1. Several support columns 13 are fixedly connected to the inner wall of the mounting frame 1. Each support column 13 has a limiting wheel body 14 rotatably connected to its outer surface. Several positioning blocks 3 are fixedly connected to the outer surface of the mounting frame 1. Each positioning block 3 has a positioning hole 4 on its upper surface. The positioning block 3 can be used as an installation reference. The operator only needs to align the structure with the preset installation position of the roving frame through the positioning hole 4, and then fix it with bolts and other connecting parts to quickly complete the precise installation.

[0019] Two curved grooves 2 are formed on the outer surface of the mounting frame 1. The inner walls of the two curved grooves 2 are slidably connected to the lead post 7. Several fixing blocks 5 are fixedly connected to the upper surface of the mounting frame 1. Each fixing block 5 has a pull ring 6 rotatably connected to its inner wall. The fixing blocks 5 and pull rings 6 provide convenience for the handling and maintenance of the structure. During the production and transportation of the structure or during the later disassembly and maintenance, the staff can easily move the entire structure by pulling the pull rings 6.

[0020] A push plate 8 is slidably connected to the outer surface of the lead post 7. The outer surface of the push plate 8 is slidably connected to the inner wall of the mounting frame 1. Both ends of the lead post 7 are fixedly connected to retaining rings 16. The side of the two retaining rings 16 that are close to each other is in contact with the outer surface of the mounting frame 1. The retaining rings 16 can axially limit the lead post 7 from both ends to ensure that the lead post 7 always slides stably within the preset trajectory and avoids the problem of wire threading interruption caused by the lead post 7 falling off.

[0021] A stabilizing block 21 is fixedly connected to one end of the lead post 7 near the push plate 8. The outer surface of the stabilizing block 21 is slidably connected to the inner wall of the push plate 8. A reinforcing ring 15 is fixedly connected to both ends of each support post 13. The side of each set of reinforcing rings 15 that is far away from each other is fixedly connected to the inner wall of the mounting frame 1. The reinforcing ring 15 increases the contact area between the support post 13 and the mounting frame 1, dispersing the force on the support post 13 to a larger area of ​​the mounting frame 1, reducing the risk of loosening of the connection.

[0022] The inner wall of the push plate 8 is threaded with a screw 9, and the inner wall of the lead post 7 is slidably connected with a pressing plate 17. Both ends of the screw 9 are rotatably connected with support blocks 10. The side of each support block 10 near the mounting frame 1 is fixedly connected to the side of the mounting frame 1 near the screw 9. The support block 10 can stably fix the screw 9 in a preset position, ensuring that the screw 9 always maintains coaxiality when rotating, thereby ensuring that the push plate 8 can move smoothly in a preset direction.

[0023] A pull column 18 is fixedly connected to the outer surface of the extrusion plate 17. The outer surface of the pull column 18 is slidably connected to the inner wall of the lead post 7. A rotating block 11 is fixedly connected to the left end of the screw 9. Several anti-slip grooves 12 are provided on the outer surface of the rotating block 11. The rotating block 11 increases the area of ​​force application by the hand, and the anti-slip grooves 12 increase the friction between the hand and the rotating block 11. The operator can easily rotate the rotating block 11 to drive the screw 9 to rotate.

[0024] A strong spring 19 is fixedly connected to the side of the extrusion plate 17 near the pull column 18. The end of the strong spring 19 away from the extrusion plate 17 is fixedly connected to the inner wall of the lead post 7. A pull head 20 is fixedly connected to the end of the pull column 18 away from the lead post 7. The side of the pull head 20 near the pull column 18 contacts the side of the lead post 7 away from the mounting frame 1. The pull head 20 increases the force-bearing area at the end of the pull column 18, and the operator can easily pull the pull head 20 to move the pull column 18 and the extrusion plate 17, and quickly complete the yarn clamping work.

[0025] The working principle of this utility model is as follows: When in use, the operator first installs the device into the predetermined position on the roving frame through the positioning block 3 and the positioning hole 4. Then, the operator pulls the pull head 20, which drives the pull column 18 and the extrusion plate 17 to move. The strong spring 19 is compressed, and at this time, the internal space of the lead column 7 is opened. The operator places the lead end of the yarn into the lead column 7 and releases the pull head 20. Under the elastic force of the strong spring 19, the extrusion plate 17 extrudes and fixes the yarn, thus completing the installation of the yarn on the lead column 7. Next, the operator rotates the rotating block 11, which drives the screw 9 to rotate. Since the push plate 8 is threadedly connected to the screw 9, and the outer surface of the push plate 8 is slidably connected to the inner wall of the mounting frame 1, the rotation of the screw 9 will drive the push plate 8 to move along the axial direction of the screw 9. During the movement of the push plate 8, it pushes the lead thread 7. The lead thread 7 slides along the curved groove 2 on the mounting frame 1. Guided by the curved groove 2, the lead thread 7 moves flexibly with the yarn, approaching each limiting wheel body 14 in turn, and smoothly passing through the top and bottom of the limiting wheel body 14 to complete the threading work. The whole process does not require The staff manually guides the yarn through multiple limiting wheels, which greatly improves the threading efficiency and ensures the normal operation of the roving machine. When the guide post 7 moves inside the curved groove 2, since the curved groove 2 is a wave-shaped slide, the guide post 7 will slide up and down in the curved groove 2. At the same time, the guide post 7 also slides up and down inside the push plate 8, so that it can pass through the upper and lower parts of the limiting wheel body 14 in sequence. Finally, when the guide post 7 moves to the end of the curved groove 2, the yarn is taken out from the guide post 7 and pulled tight until it fits against the groove of the limiting wheel body 14 to limit and protect it.
