Description

Technical Field

[0001] This utility model relates to the field of roving frame technology, and more specifically, to a pressing structure for a roving frame spindle. Background Technology

[0002] The main function of a roving frame is to further draft and twist the roving (yarn) after the drawing process, and wind it into roving with a certain density and shape. Among them, the spindle and the pressure plate are two key twisting and winding components. They work together to complete the twisting, guiding and shaping winding tasks of the roving.

[0003] During operation, the spindle blade drives the pressure palm to rotate together. The spindle blade twists the sliver coming out of the drafting zone of the roller to form roving. After the sliver enters the hollow arm of the spindle blade, it is drawn out from the yarn outlet at the bottom of the hollow arm. The drawn roving is then guided to the appropriate position on the bobbin by the pressure palm. As the diameter of the roving wound on the bobbin gradually increases, the pressure palm will also rotate and open adaptively along the hollow arm of the spindle blade.

[0004] However, during current operation, when the roving passes through the round yarn hole of the pressure palm from the hollow arm of the spindle, the pressure palm gradually rotates to adapt as the diameter of the roving in the bobbin increases. As a result, the round yarn hole of the pressure palm and the yarn outlet of the hollow arm become misaligned, causing the roving to be poorly guided. Furthermore, the collision and friction between the roving and the hole wall are quite severe, and phenomena such as fiber accumulation and entanglement also occur at the pressure palm, resulting in significant fiber loss. This not only affects the quality of the roving but also increases the cleaning workload for workers.

[0005] Therefore, it is necessary to provide a palm-pressing structure for the spindle blade of a roving frame to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a pressing structure for the spindle wing of a roving frame to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A pressure palm structure for a roving frame spindle wing, mounted on a hollow arm of the spindle wing, wherein the bottom of the hollow arm has a yarn outlet hole, comprising: The main body of the presser is detachably installed on the hollow arm and is used to guide and press the roving out of the yarn outlet hole onto the bobbin to form a shape. The palm pressing body includes a connecting section, a palm pressing arm, and a palm pressing blade. The two ends of the palm pressing arm are respectively connected to the connecting section and the palm pressing blade. A yarn guide hole is provided on the connecting section and corresponds to the position of the yarn outlet hole. A yarn guide hole for roving to pass through is provided on the pressing blade. Connectors are detachably connected to the hollow arm and the palm press body, respectively.

[0008] Furthermore, the connector includes: The connecting plate is detachably connected to the hollow arm; An adapter is provided on the connecting plate. The adapter is detachably connected to the palm press body. When the palm press body is subjected to force, it will rotate along the connecting axis of the adapter, and when no force is applied, it will return to its original position.

[0009] Furthermore, the adapter has an internal cavity, and a connecting shaft is rotatably mounted on the inner wall of the cavity. The outer end of the connecting shaft extends to the outside of the adapter and is connected to the connecting section. The inner wall of the cavity is provided with a torsion spring, and the other end of the torsion spring is connected to the connecting shaft.

[0010] Furthermore, a limiting plate is provided on the connecting shaft, a sliding ring plate is provided on the outer wall of the limiting plate, and an annular groove is provided on the inner wall of the inner cavity to slide and connect with the sliding ring plate.

[0011] Furthermore, the outer end of the connecting shaft is provided with a mounting plate, the other end of the mounting plate is provided with a fixing stud, and the connecting section is provided with a mounting hole that matches the fixing stud.

[0012] Furthermore, the connecting plate is provided with fixing holes, and the outer wall of the hollow arm is provided with a plurality of threaded holes that are adapted to the fixing holes.

[0013] Furthermore, an adjusting rod is slidably inserted inside the palm pressing arm, the outer end of the adjusting rod is connected to the palm pressing blade, and a fastening bolt is threaded onto the palm pressing arm to limit the position of the adjusting rod.

[0014] Furthermore, a plurality of support seats are provided on the side of the pressing blade facing the cylinder, and a roller is rotatably mounted on the support seat.

[0015] Furthermore, the inside of the palm pressing blade is provided with an inner recessed groove that is slidably connected to the support base, and an elastic element is provided between the inner wall of the inner recessed groove and the support base.

[0016] Furthermore, the elastic element includes a spring and a damper, with the spring sleeved on the outside of the damper.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. At the start of winding, the roving is pressed onto the bobbin by the pressure blade, which facilitates the establishment of initial winding tension and prevents the roving from loosening or coming off the loop. As the winding diameter of the roving on the bobbin increases, the pressure blade will rotate along the connection axis with the connector. That is, the pressure blade will adaptively rotate outward and open as the diameter of the roving on the bobbin increases. With the cooperation of the connector, it is ensured that the pressure blade can always press lightly on the surface of the roving that is forming on the bobbin, thereby improving the winding effect of the roving on the bobbin.

[0018] 2. During the continuous rotation and opening of the presser body, although the yarn guide hole also rotates slightly with the connecting section, due to the elongated oval shape of the yarn guide hole, it will not be misaligned with the yarn outlet hole. The process of the roving entering the yarn guide hole from the yarn outlet hole is very smooth, greatly reducing the collision and friction between the roving and the hole wall. This effectively reduces the accumulation and entanglement of roving at the presser body, preventing more fiber loss. It not only improves the quality of roving winding but also reduces the cleaning workload of the staff and improves the working efficiency of the roving machine.

[0019] 3. The palm presser body is connected to the hollow arm via a connector, which allows for easy disassembly of the palm presser body and connector. This facilitates cleaning and maintenance of the palm presser body, saving time and effort and improving work efficiency. When the palm presser body is damaged, it can be easily replaced, reducing downtime. It also lowers the difficulty of installing and disassembling the palm presser body, thereby reducing the operating threshold and making it easier for ordinary operators to replace.

[0022] 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.

[0023] Please see Figure 1-7 A pressure palm structure for a roving frame spindle wing, mounted on a hollow arm 1 of the spindle wing, wherein a yarn outlet hole 2 is provided at the bottom of the hollow arm 1, comprising: The pressing body 3 is detachably installed on the hollow arm 1 and is used to guide and press the roving out of the yarn outlet 2 onto the bobbin to form a shape. The palm pressing body 3 includes a connecting section 31, a palm pressing arm 32, and a palm pressing blade 33. The two ends of the palm pressing arm 32 are respectively connected to the connecting section 31 and the palm pressing blade 33. The yarn guide hole 4 is opened on the connecting section 31 and corresponds to the position of the yarn outlet hole 2. The pressing blade 33 is provided with a yarn guide hole 5 for the roving to pass through. Connector 6 is detachably connected to hollow arm 1 and palm press body 3 respectively.

[0024] In use, the roving is drawn out from the yarn outlet 2 of the hollow arm 1, then passes through the yarn guide elongated hole 4 of the connecting section 31 on the palm presser body 3, then is wound on the palm presser arm 32 and then passes through the yarn guide hole 5 of the palm presser blade 33, and finally wound onto the bobbin; at the beginning of winding, the roving is pressed onto the bobbin by the palm presser blade 33, which facilitates the establishment of initial winding tension and prevents the roving from loosening and coming off the loop.

[0025] As the diameter of the roving on the bobbin increases, the pressure palm body 3 will rotate along the connection axis with the connector 6. That is, the pressure palm body 3 will adaptively rotate outward and open as the diameter of the roving on the bobbin increases. With the cooperation of the connector 6, the pressure palm blade 33 can always gently press on the surface of the roving that is being formed on the bobbin, thereby improving the winding effect of the roving on the bobbin.

[0026] Furthermore, as the palm press body 3 rotates and opens continuously, although the yarn guide elongated hole 4 also rotates slightly with the connecting section 31, due to the characteristic of the yarn guide elongated hole 4 being an elongated oval hole, the yarn guide elongated hole 4 can always maintain a state of being directly aligned with the yarn outlet hole 2 of the hollow arm 1. That is, the yarn guide elongated hole 4 will not be misaligned with the yarn outlet hole 2, thus ensuring that the process of the roving entering the yarn guide elongated hole 4 from the yarn outlet hole 2 is always very smooth, greatly reducing the collision and friction between the roving and the hole wall. This effectively reduces the accumulation and entanglement of roving at the palm press body 3, preventing more fiber loss. It not only improves the quality of roving winding and forming, but also reduces the cleaning workload of the staff, and at the same time improves the working efficiency of the roving machine.

[0027] Furthermore, the palm presser body 3 is connected to the hollow arm 1 via the connector 6, allowing for easy disassembly of the palm presser body 3 and the connector 6. This facilitates easier cleaning and maintenance of the palm presser body 3, saving time and effort and improving work efficiency. When the palm presser body 3 is damaged, it can be easily replaced, reducing downtime and impact on the operation of the roving frame. It also lowers the difficulty of installing and disassembling the palm presser body 3, thus reducing the operational threshold and making it more suitable for ordinary operators to replace, demonstrating strong practicality.

[0028] For preferred options, please refer to [link / reference]. Figure 2-3 and Figure 5 The connector 6 includes: Connecting plate 61 is detachably connected to hollow arm 1; The adapter 62 is located on the connecting plate 61. The adapter 62 is detachably connected to the palm press body 3. When the palm press body 3 is subjected to force, it will rotate along the connecting axis of the adapter 62, and when it is not subjected to force, it will return to its original position.

[0029] Specifically, when installing the palm presser body 3, the connecting plate 61 can be connected to the hollow arm 1 first, and then the palm presser body 3 can be connected to the adapter 62; alternatively, the palm presser body 3 can be connected to the adapter 62 first, and then the connecting plate 61 can be connected to the hollow arm 1, whichever is required.

[0030] As the diameter of the roving on the bobbin continues to increase, the pressure body 3 will rotate along the connecting axis with the adapter 62 under the force, thus ensuring that the pressure blade 33 of the pressure body 3 can always gently press on the surface of the forming roving tube; when the pressure body 3 is not under force, the pressure body 3 will rotate and reset along the connecting axis with the adapter 62, without affecting the next operation.

[0031] In this embodiment, preferably, please refer to [reference needed]. Figure 6 The adapter 62 has an inner cavity 7 inside, and a connecting shaft 8 is rotatably mounted on the inner wall of the inner cavity 7. The outer end of the connecting shaft 8 extends to the outside of the adapter 62 and is connected to the connecting section 31. The inner wall of the inner cavity 7 is provided with a torsion spring 9, and the other end of the torsion spring 9 is connected to the connecting shaft 8.

[0032] Specifically, as the diameter of the roving on the bobbin increases, the pressure palm body 3 is subjected to force, which drives the connecting shaft 8 to rotate and open through the connecting section 31. The rotation of the connecting shaft 8 causes the torsion spring 9 to be subjected to torque and gradually twist and deform elastically. At the same time, the torsion spring 9 will exert a reaction force on the connecting shaft 8, which will in turn exert a reaction force on the pressure palm body 3 connected to the connecting shaft 8, so that the pressure palm blade 33 of the pressure palm body 3 can always press lightly on the surface of the roving that is being formed on the bobbin, thereby improving the winding effect.

[0033] When the palm pressing body 3 is not subjected to force, it rotates through the internal restoring force of the torsion spring 9, converting the stored potential energy into kinetic energy and releasing it, which in turn drives the connecting shaft 8 and the palm pressing body 3 to rotate and reset.

[0034] For preferred options, please refer to [link / reference]. Figure 6 A limiting plate 10 is provided on the connecting shaft 8. A sliding ring plate 11 is provided on the outer wall of the limiting plate 10. An annular groove that is slidably connected to the sliding ring plate 11 is provided on the inner wall of the inner cavity 7.

[0035] Specifically, when the connecting shaft 8 rotates, it will drive the limiting plate 10 and the sliding ring plate 11 to rotate. The sliding ring plate 11 will rotate along the annular groove of the inner cavity 7, which can not only improve the rotational stability of the connecting shaft 8 and the palm pressing body 3, but also provide a certain support for the connecting shaft 8, share the vertical force on the connecting shaft 8, and further improve the operational stability of the connecting shaft 8.

[0036] For preferred options, please refer to [link / reference]. Figure 3-6 The outer end of the connecting shaft 8 is provided with a mounting plate 12, and the other end of the mounting plate 12 is provided with a fixing stud 13. The connecting section 31 is provided with a mounting hole 14 that is adapted to the fixing stud 13.

[0037] With this design, when connecting the palm presser body 3 to the adapter 62, the fixing stud 13 on the mounting plate 12 can be inserted into the mounting hole 14 of the connecting section 31, and then fixed by rotating the nut from below the connecting section 31 onto the fixing stud 13. Figure 3 In the state shown, the palm press body 3 can be fixedly connected to the mounting plate 12 and the adapter 62; When it is necessary to remove the palm presser body 3, simply unscrew the nut on the fixing stud 13 to remove the palm presser body 3. The disassembly and assembly are simple and convenient, saving time and effort, and facilitating maintenance, cleaning and replacement.

[0038] In this embodiment, preferably, please refer to [reference needed]. Figure 2-3 and Figure 5 The connecting plate 61 has a fixing hole 15, and the outer wall of the hollow arm 1 has a plurality of threaded holes 16 that are adapted to the fixing hole 15.

[0039] With this design, when connecting the connecting plate 61 to the hollow arm 1, the fixing hole 15 of the connecting plate 61 can be aligned with the threaded hole 16 on the hollow arm 1, and then the connecting plate 61 can be fixed by passing bolts or screws through the fixing hole 15 into the threaded hole 16. The operation is simple and convenient.

[0040] Furthermore, the fixing holes 15 of the connecting plate 61 can be aligned with the threaded holes 16 at different height positions of the hollow arm 1 for installation, which can change the height of the adapter 62 and the palm press body 3. The distance between the palm press body 3 and the bottom of the hollow arm 1 can be adjusted as needed to meet the adjustment requirements in various situations. It has a wide range of applications and strong practicality.

[0041] In this embodiment, preferably, please refer to [reference needed]. Figure 2-4 An adjusting rod 17 is slidably inserted inside the palm pressing arm 32. The outer end of the adjusting rod 17 is connected to the palm pressing blade 33. A fastening bolt 18 is threaded on the palm pressing arm 32 to limit the position of the adjusting rod 17.

[0042] With this design, after loosening the fastening bolt 18, the adjusting rod 17 can be slid back and forth along the inner side of the pressure arm 32, thereby changing the distance between the pressure blade 33 and the pressure arm 32. This allows adjustment of the position of the pressure blade 33 pressing against the surface of the bobbin roving, achieving a better roving winding effect. After adjustment, tightening the fastening bolt 18 will cause the end of the fastening bolt 18 to press against the surface of the adjusting rod 17, thus limiting and fixing the position of the pressure blade 33.

[0043] In this embodiment, preferably, please refer to [reference needed]. Figure 2-4 Multiple support seats 19 are provided on the side of the pressing blade 33 facing the tube, and a roller 20 is rotatably mounted on the support seat 19.

[0044] With this design, during the bobbin winding process, the roller 20 of the pressure blade 33 contacts the roving on the bobbin. The roller 20 presses the roving on the bobbin to prevent the roving from loosening or coming off the loop. Moreover, the roller 20 can reduce the friction between itself and the roving, thereby significantly reducing the wear and damage to the roving. This effectively reduces the accumulation and entanglement of roving on the pressure blade 33, reduces fiber loss, and improves the winding quality of the roving.

[0045] In this embodiment, preferably, please refer to [reference needed]. Figure 7 The palm presser blade 33 has an inner recessed groove 21 that is slidably connected to the support base 19. An elastic element 22 is provided between the inner wall of the inner recessed groove 21 and the support base 19.

[0046] With this design, when the roller 20 is subjected to compressive force, the roller 20 will drive the support seat 19 to move into the inner recess 21, and cause the elastic element 22 to undergo elastic deformation. This can avoid hard contact between the roller 20 and the roving, play a certain buffering role, and reduce damage to the roving. Furthermore, when the roller 20 is subjected to less pressure or no pressure, the elastic element 22 will drive the support seat 19 and the roller 20 to move and reset, and can enable the roller 20 to better and always gently press on the surface of the forming bobbin roving, improving the winding effect.

[0047] In this embodiment, preferably, please refer to [reference needed]. Figure 7 The elastic element 22 includes a spring 221 and a damper 222, with the spring 221 sleeved on the outside of the damper 222.

[0048] With this design, when the bracket 19 is pressed and moves into the inner recess 21, the spring 221 is compressed and deformed by the pressure, and the damper 222 is compressed and contracted. When the external force on the bracket 19 is removed, the spring 221 will rebound, and the damper 222 will also extend and return to its original position.

[0049] The combined action of spring 221 and damper 222 can improve the buffering performance and reset effect of support base 19 and roller 20, so that roller 20 always keeps pressed on the surface of bobbin roving, resulting in good performance.
