Description

Technical Field

[0001] This application relates to the technical field of guide belt drive components, and in particular to the guide belt drive components of the JWF1313 first-stage drawing frame. Background Technology

[0002] The drawing process is a crucial step in the spinning process. Its core task is to improve the evenness and fiber arrangement of the sliver by combining and drafting multiple slivers. As a core component of the first drawing frame, the guide belt drive directly affects the stability of sliver transport and the efficiency of equipment operation. The drawing frame is a key piece of equipment in the spinning process for "improving yarn evenness and reducing weight unevenness". The first drawing frame needs to take the raw sliver (containing impurities and loose structure) output from the carding machine and form it into a mature sliver by multi-roller drafting and combining multiple slivers, providing high-quality cotton products for subsequent roving and spinning processes. The core function of its guide system is to accurately and smoothly transport the sliver to the drafting mechanism.

[0003] The existing device has an I-shaped faucet short shaft support with an abnormal ratio of drive belt to guide belt. On one side of the support, there is one drive belt and on the other side, there are two drive belts, which causes an imbalance in the transmission. This results in severe wear of the faucet short shaft. Furthermore, due to the unreasonable design of the guide belt drive component of the JWF1313 first-stage drawing frame, the components on the connecting shaft are easily unable to be separated, leading to wear of the components and the short shaft due to friction.

[0004] Therefore, a new approach is needed to solve this problem. Utility Model Content

[0005] The purpose of this application is to provide a guide belt drive component for the JWF first-stage drawing frame, which has the advantages of reducing wear caused by friction between adjacent components and solves the problem that existing devices cannot separate the components on the connecting shaft, resulting in wear between components due to friction.

[0006] The technical solution of the guide belt drive component for the JWF1313 first-stage drawing frame provided in this application is as follows: The guide belt drive component for the JWF1313 first-stage drawing frame includes a U-shaped frame, two connecting rings are fixedly connected to the outer surface of the U-shaped frame, a connecting shaft is provided above the U-shaped frame, two limiting grooves are opened on the outer surface of the connecting shaft, a limiting block is inserted into the inner wall of each limiting groove, a first spacer ring is fixedly connected to the upper surface of the connecting shaft, and a first threaded groove is opened on the outer surface of the connecting shaft.

[0007] By adopting the above technical solution, the U-shaped frame, as the basic support component of the whole, needs to bear the combined loads such as belt tension and rotational inertia force of the connecting shaft. The improvement of the U-shaped frame can achieve bidirectional force balance, reduce vibration amplitude, and indirectly improve the smoothness of belt drive. The connecting shaft is the core rotating component of the guide pulley, and its axial stability directly affects the belt tension and the risk of deviation. Through the insertion and cooperation of the limiting groove and the limiting block, the subsequent parts can be mechanically limited and slidably constrained. The first spacer ring is located on the upper surface of the connecting shaft. Its function is to separate the pulley on the connecting shaft from other components, and to prevent the parts from rubbing against each other and causing abnormal noise or wear when the connecting shaft rotates.

[0008] Preferably, a transmission pulley is provided between the two connecting rings, and the inner wall of the transmission pulley is slidably connected to the connecting shaft.

[0009] By adopting the above technical solution, two connecting rings are symmetrically distributed on both sides of the transmission pulley, forming a spatial constraint of left and right clamping. During the installation of the transmission pulley, the transmission pulley is placed between the two connecting rings, and then inserted along the connecting shaft through one end of the connecting ring, and the transmission pulley is slid horizontally along the connecting shaft. In this way, the U-shaped frame and the transmission pulley can be quickly installed.

[0010] Preferably, the outer surface of the connecting shaft is slidably connected to two guide wheel drives, each guide wheel drive has a connecting groove on its inner wall, and the inner wall of each connecting groove is slidably connected to a corresponding limiting block.

[0011] By adopting the above technical solution, the guide bar drive wheel and the connecting shaft are slidably connected, but the torque is transmitted through the cooperation of the connecting groove and the limiting block, forming a unique structure that is axially movable and circumferentially fixed. Through the sliding cooperation of the connecting groove and the limiting block, it is ensured that the guide bar drive wheel rotates synchronously with the connecting shaft without relative circumferential displacement, thus avoiding the slippage problem of traditional friction transmission.

[0012] Preferably, the outer surface of the connecting shaft is slidably connected to two bearings, and the outer surface of each bearing is in contact with the corresponding guide bar drive wheel.

[0013] By adopting the above technical solution, the inner ring of the bearing can slide synchronously with the guide bar drive wheel along the connecting shaft axis without affecting the adjustment function of the drive wheel spacing, thus achieving compatibility between smooth rotation and position adjustability.

[0014] Preferably, a second spacer ring is slidably connected to the outer surface of the connecting shaft, and the side of each bearing away from the corresponding guide wheel is in contact with the corresponding first spacer ring and second spacer ring.

[0015] By adopting the above technical solution, after the U-shaped frame and the transmission pulley are installed, one of the bearings is then inserted horizontally along the connecting shaft until it is in contact with the first spacer ring. During the installation of the other bearing, the second spacer ring needs to be installed first, and then the other bearing is in contact with the second spacer ring. At this time, the second spacer ring will contact the transmission pulley. Finally, the guide bar drive wheel is installed.

[0016] Preferably, the outer surface of the transmission pulley is provided with a mounting groove, and the inner wall of the mounting groove is provided with a sliding groove and a plurality of second threaded grooves.

[0017] By adopting the above technical solution, the transmission pulley, as the direct load-bearing structure of the transmission belt, directly affects the transmission efficiency and stability of the belt. The inner wall of the mounting groove is provided with a sliding groove, the size of which is the same as the first threaded groove. There are four second threaded grooves, which are evenly distributed around the sliding groove.

[0018] Preferably, a connecting frame is slidably connected to the inner wall of the mounting groove, and a plurality of fixing bolts are inserted into the inner wall of the connecting frame, wherein the outer surface of each fixing bolt is threadedly connected to the corresponding second thread groove.

[0019] By adopting the above technical solution, the connecting bracket can be quickly fixed by vertically inserting it along the corresponding mounting groove, and then using fixing bolts to vertically insert it along the connecting bracket until it is connected with the corresponding second threaded groove.

[0020] Preferably, a threaded rod is inserted into the inner wall of the groove, and the outer surface of the threaded rod is threadedly connected to the first threaded groove.

[0021] By adopting the above technical solution, before installing the connecting frame, it is necessary to rotate the transmission pulley so that the slide groove and the first threaded groove are on the same central axis, and then insert the threaded rod vertically along the slide groove until it is connected to the first threaded groove, so that the transmission pulley can be quickly connected.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] The JWF first-stage drawing frame guide belt drive component, through the setting of components such as U-shaped frame, connecting ring, connecting shaft, limiting groove, limiting block, first spacer ring, and first threaded groove, forms a centrally symmetrical structure by setting the U-shaped frame and connecting ring. The main drive of the machine head is located in the middle, and when transmitting power to the guide belt drive systems on both sides, the path length and angle are basically the same, forming a symmetrical power distribution mode, which makes the overall force of the equipment balanced. The setting of the first spacer ring can provide a clear axial separation benchmark for adjacent components, thereby achieving the effect of avoiding direct contact between different functional components and reducing wear of parts.

[0032] Example 1: Guide belt drive component of JWF1313 first drawing frame, refer to Figure 1 , Figure 2 , Figure 4 The system includes a U-shaped frame 1, with two connecting rings 2 fixedly connected to the outer surface of the U-shaped frame 1. A connecting shaft 3 is located above the U-shaped frame 1, and two limiting grooves 4 are opened on the outer surface of the connecting shaft 3. A limiting block 6 is inserted into the inner wall of each limiting groove 4. A first spacer ring 5 is fixedly connected to the upper surface of the connecting shaft 3, and a first threaded groove 7 is opened on the outer surface of the connecting shaft 3. As the basic support component of the whole, the U-shaped frame 1 needs to bear the combined loads such as belt tension and rotational inertia force of the connecting shaft 3. The improvement of the U-shaped frame 1 can achieve bidirectional force balance, reduce vibration amplitude, and indirectly improve the smoothness of belt drive. The connecting shaft 3 is the core rotating component of the guide pulley, and its axial stability directly affects the belt tension and the risk of deviation. Through the insertion and cooperation of the limiting grooves 4 and the limiting blocks 6, the subsequent parts can be mechanically limited and slidably constrained. The first spacer ring 5 is located on the upper surface of the connecting shaft 3, and its function is to separate the pulley on the connecting shaft 3 from other components, so as to avoid the abnormal noise or wear caused by the friction between the parts when the connecting shaft 3 rotates.

[0033] Example 2: Belt drive components for the guide strip of the JWF1313 first drawing frame, such as... Figure 3 , Figure 4 , Figure 5 Based on the same concept as Embodiment 1 above, this embodiment proposes that a transmission pulley 10 is provided between the two connecting rings 2. The inner wall of the transmission pulley 10 is slidably connected to the connecting shaft 3. The two connecting rings 2 are symmetrically distributed on both sides of the transmission pulley 10, forming a spatial constraint of left and right clamping. During the installation of the transmission pulley 10, the transmission pulley 10 is placed between the two connecting rings 2, and then inserted along the connecting shaft 3 through one end of the connecting ring 2, and the transmission pulley 10 is slid horizontally along the connecting shaft 3. In this way, the U-shaped frame 1 and the transmission pulley 10 can be quickly installed.

[0034] Please see Figure 1 , Figure 2 , Figure 3 Two guide wheel 17 are slidably connected to the outer surface of the connecting shaft 3. Each guide wheel 17 has a connecting groove 18 on its inner wall. The inner wall of each connecting groove 18 is slidably connected to the corresponding limiting block 6. The guide wheel 17 and the connecting shaft 3 are slidably connected, but torque is transmitted through the cooperation of the connecting groove 18 and the limiting block 6, forming a unique structure that is axially movable and circumferentially fixed. Through the sliding cooperation of the connecting groove 18 and the limiting block 6, it is ensured that the guide wheel 17 rotates synchronously with the connecting shaft 3 without relative circumferential displacement, thus avoiding the slippage problem of traditional friction transmission.

[0035] Please see Figure 3 , Figure 4 Two bearings 8 are slidably connected to the outer surface of the connecting shaft 3. The outer surface of each bearing 8 is in contact with the corresponding guide wheel 17. The inner ring of the bearing 8 can slide synchronously with the guide wheel 17 along the axial direction of the connecting shaft 3 without affecting the adjustment function of the transmission wheel spacing, thus achieving compatibility between smooth rotation and position adjustability.

[0036] Please see Figure 4 The outer surface of the connecting shaft 3 is slidably connected with a second spacer ring 9. The side of each bearing 8 away from the corresponding guide wheel 17 is in contact with the corresponding first spacer ring 5 and second spacer ring 9. After the U-shaped frame 1 and the drive pulley 10 are installed, one of the bearings 8 is horizontally inserted along the connecting shaft 3 until it is in contact with the first spacer ring 5. During the installation of the other bearing 8, the second spacer ring 9 needs to be installed first, and then the other bearing 8 is in contact with the second spacer ring 9. At this time, the second spacer ring 9 will contact the drive pulley 10. Finally, the guide wheel 17 is installed.

[0037] Please see Figure 5The outer surface of the transmission pulley 10 is provided with an installation groove 11. The inner wall of the installation groove 11 is provided with a sliding groove 12 and several second threaded grooves 13. As the direct load-bearing structure of the transmission belt, the design of the transmission pulley 10 directly affects the transmission efficiency and stability of the belt. The inner wall of the installation groove 11 is provided with a sliding groove 12, the size of which is the same as that of the first threaded groove 7. There are four second threaded grooves 13, which are evenly distributed around the sliding groove 12.

[0038] Please see Figure 5 The inner wall of the mounting groove 11 is slidably connected to a connecting bracket 14. Several fixing bolts 15 are inserted into the inner wall of the connecting bracket 14. The outer surface of each fixing bolt 15 is threadedly connected to the corresponding second threaded groove 13. By vertically inserting the connecting bracket 14 along the corresponding mounting groove 11, and then using the fixing bolts 15 to vertically insert it along the connecting bracket 14 until it is connected to the corresponding second threaded groove 13, the connecting bracket 14 can be quickly fixed.

[0039] Please see Figure 4 , Figure 5 A threaded rod 16 is inserted into the inner wall of the slide groove 12. The outer surface of the threaded rod 16 is threadedly connected to the first threaded groove 7. Before installing the connecting frame 14, the transmission pulley 10 needs to be rotated so that the slide groove 12 and the first threaded groove 7 are on the same central axis. Then, the threaded rod 16 is vertically inserted along the slide groove 12 until it is connected to the first threaded groove 7. This allows for quick connection of the transmission pulley 10.

[0040] The implementation principle of this application embodiment is as follows: First, the transmission pulley 10 is placed between the two connecting rings 2. Then, the U-shaped frame 1 and the transmission pulley 10 are slid horizontally along the connecting shaft 3 until the transmission pulley 10 contacts the first spacer ring 5. At this time, the second spacer ring 9 is taken and horizontally inserted into the connecting shaft 3 from the other side of the transmission pulley 10 until it contacts the transmission pulley 10. Then, the bearing 8 is taken and horizontally inserted along both sides of the connecting shaft 3 until the bearing 8 contacts the corresponding first spacer ring 5 or second spacer ring 9. During this process, the bearing 8 will be engaged in the corresponding connecting ring 2. At this time, by rotating the transmission pulley 10, the sliding groove 12 and the first threaded groove 7 are on the same central axis. Insert the threaded rod 16 vertically along the slide groove 12 until it connects with the first threaded groove 7. This allows for a quick connection between the transmission pulley 10 and the connecting shaft 3. Then, take the connecting bracket 14 and place it over the threaded rod 16. Insert the connecting bracket 14 vertically along the corresponding mounting groove 11. Then, use the fixing bolt 15 and insert it vertically along the connecting bracket 14 until it connects with the corresponding second threaded groove 13. This allows for a quick fixation of the connecting bracket 14. Finally, insert the limiting block 6 vertically along the corresponding limiting groove 4 and connect the corresponding guide bar drive wheel 17 to the connecting shaft 3. The limiting block 6 will engage with the corresponding connecting groove 18. This allows for a quick installation of the guide bar drive wheel 17.
