Description

Technical Field

[0001] This invention belongs to the field of winding machine technology, and specifically relates to a spindle mounting device for a chemical fiber winding machine. Background Technology

[0002] According to their operating methods, winding machines can be divided into: manual winding machines, semi-automatic winding machines, and fully automatic winding machines. The winding machine spindle is one of the main components of the winding machine, and is an assembly mainly composed of a slender rotating shaft supported at two points. In existing technology, the spindle drives the yarn bobbin to rotate under the operation of the drive device. Due to the high-intensity work of the spindle, its service life will shorten with the length of use. Existing technology requires disassembling the spindle for thorough lubrication by first disassembling the drive spindle housing and then using specialized tools to remove the screws connecting the spindle and the drive device shaft, resulting in a long spindle maintenance time. To ensure stable spindle rotation, existing technology typically installs a bearing on top of the spindle, with the bearing inner ring fixed to the spindle and the bearing connecting bracket fixed to the machine. This leads to higher operating costs after spindle disassembly and replacement. Therefore, an improvement is needed, and a new spindle installation device for a chemical fiber winding machine is proposed. Summary of the Invention

[0003] In response to the problems mentioned in the background art, the present invention provides a spindle installation device for a chemical fiber winding machine that requires no special tools, is easy to assemble and disassemble, and allows the spindle to rotate stably.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A spindle mounting device for a chemical fiber winding machine, characterized in that it includes a spindle connecting mechanism, a spindle body, and a spindle stabilizing mechanism;

[0006] The spindle connecting mechanism includes a shaft, a circular plate, and a support bearing. The shaft is fixedly connected to one side of the circular plate, and the support bearing is fixedly connected to the side of the circular plate opposite to the shaft. An installation rod is rotatably connected inside the support bearing.

[0007] The spindle body is rotatably inserted into the spindle stabilizing mechanism and detachably mounted to the end of the mounting rod via a docking assembly; the direction along the radial direction of the spindle body closer to the central axis of the spindle body is defined as inside, and the opposite direction is defined as outside;

[0008] The stabilizing mechanism includes a stabilizing connection mechanism and a side frame. The stabilizing connection mechanism is connected to the support bearing through the side frame. At least two sets of radial limiting components that can be pressed against the outer wall of the spindle body are provided at intervals on the inner side of the stabilizing connection mechanism.

[0009] Preferably, the docking assembly includes a docking block, one end of which is fixedly connected to one end of the spindle body, and the other end of which is inserted into a docking opening groove at the end of the mounting rod, and is detachably connected to the mounting rod via a fixing assembly.

[0010] Preferably, the outer side of the docking block is provided with an outward-facing radial opening groove, and a first rubber pad is fixedly connected to the inner wall of the radial opening groove.

[0011] Preferably, the fixing assembly includes a sliding plate and a spring slide rod and a fixing rod disposed inside the mounting rod. The spring, slide rod, and fixing rod are all arranged radially along the spindle body. The slide rod passes through the spring, and the inner end of the slide rod is fixedly connected to the inner end of the spring. The inner end of the slide rod connected to the spring is fixedly connected to the outer end of the fixing rod. The inner end of the fixing rod is inserted into the radial opening groove of the mating block. The outer end of the slide rod away from the fixing rod passes through the through hole in the side wall of the mounting rod and is fixedly connected to the sliding plate.

[0012] Preferably, a sound-absorbing pad is fixedly connected to the inner surface of the sliding plate facing the mounting rod, for fitting against the outer surface of the mounting rod.

[0013] Preferably, the stabilizing connection mechanism includes an outer tube and an inner tube that are sleeved and rotated together. The outer tube is connected to a support bearing through a side frame. The inner wall of the inner tube is connected to several sets of radial limiting components that can extend and retract along the spindle body. The inner end of the radial limiting components presses against the outer wall of the spindle body and moves in cooperation with the spindle body.

[0014] Preferably, the outer wall of the spindle body is provided with an annular pressing groove along the circumferential direction.

[0015] Preferably, the radial limiting component includes a compression spring, which is fixedly connected to the inner wall of the inner tube, and a compression block is fixedly connected to the inner end of the compression spring. The compression block is inserted into the annular compression groove of the spindle body.

[0016] Preferably, the cross-section of the clamping block is an arc-shaped structure adapted to the annular clamping groove.

[0017] Preferably, a second rubber pad is fixedly connected to the inner wall surface of the annular pressing groove.

[0018] In summary, the present invention has the following main beneficial effects:

[0019] First, when the spindle body needs to be removed for full oiling and maintenance, the operator pulls the moving plate, which causes the sliding rod to slide to one side. The sliding rod causes the fixing rod to move away from the insert block. Then, the operator holds the spindle body and moves it to one side. With the cooperation of the spindle stabilizing mechanism, the spindle body can be separated from the mounting rod. Since the spindle body is detachably connected to the mounting rod, it is convenient to disassemble and assemble the spindle body without the need for professional tools. It has the characteristics of saving time and effort and simple operation, which greatly improves the oiling and maintenance time of the spindle body.

[0020] Secondly, this invention installs side frames on both sides of the support bearing, fixes an outer tube to one side of the side frame, connects the outer tube to the inner tube via ball bearings, and connects the inner tube to a clamping block via a clamping spring. A clamping groove is opened on the spindle body, and the clamping block fits into the clamping groove and contacts the second rubber pad, so that the spindle body is connected to the inner tube. When the spindle body rotates, the inner tube rotates on the outer tube via ball bearings, which can stabilize the rotation of the spindle body. Moreover, this structure does not affect the disassembly and assembly of the spindle body. Attached Figure Description

[0035] The present invention will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0036] refer to Figure 1-4 The present invention provides a spindle installation device for a chemical fiber winding machine, comprising a spindle connecting mechanism 100, a spindle body 11, and a spindle stabilizing mechanism 200.

[0037] The spindle connecting mechanism 100 includes a shaft 1, a circular plate 2 and a support bearing 3. The shaft 1 is fixedly connected to one side of the circular plate 2, and the support bearing 3 is fixedly connected to the side of the circular plate 2 away from the shaft 1. An installation rod 4 is rotatably connected inside the support bearing 3.

[0038] The spindle body 11 is rotatably inserted into the spindle stabilizing mechanism 200 and is detachably mounted to the end of the mounting rod 4 via the docking assembly 5; the direction along the radial direction of the spindle body 11 closer to the central axis of the spindle body 11 is defined as inside, and the opposite direction is defined as outside;

[0039] The stabilizing mechanism 200 includes a stabilizing connection mechanism 12 and several sets of side frames 10. The stabilizing connection mechanism 12 is connected to the support bearing 3 through the side frames 10. At least two sets of radial limiting components 124 that can be pressed against the outer wall of the spindle body 11 are provided on the inner side of the stabilizing connection mechanism 12 at intervals.

[0040] In some embodiments of the present invention, the shaft 1, the circular plate 2, the support bearing 3 and the mounting rod 4 are all coaxially arranged, and the end of the mounting rod 4 away from the circular plate 2 extends out from the support bearing 3 to form a connecting end that connects to the spindle body 11.

[0041] In some embodiments of the present invention, in order to facilitate the disassembly and assembly of the spindle body 11, the docking component 5 is innovatively designed. Specifically, the docking component 5 includes a docking block 52. One end of the docking block 52 is fixedly connected to one end of the spindle body 11, and the other end of the docking block 52 is inserted into the docking opening groove 51 opened at the end of the mounting rod 4, and is detachably connected to the mounting rod 4 through the fixing component 6.

[0042] In some embodiments of the present invention, the outer side of the docking block 52 is provided with an outward-facing radial opening groove 7, and the inner wall of the radial opening groove 7 is fixedly connected with a first rubber pad 8.

[0043] In some other embodiments of the present invention, the connecting end of the mounting rod 4 is provided with a mating opening groove 51 and a side wall through hole. The side wall through hole is arranged radially along the mounting rod 4, and one end of the side wall through hole is connected to the outer wall of the mounting rod 4, and the other end is connected to the mating opening groove 51.

[0044] In some embodiments of the present invention, the fixing component 6 includes a sliding plate 63 and a spring 61, a sliding rod 62, and a fixing rod 64 disposed inside the mounting rod 4. The spring 61, the sliding rod 62, and the fixing rod 64 are all arranged radially along the spindle body 11. The sliding rod 62 passes through the spring 61, and the inner end of the sliding rod 62 is fixedly connected to the inner end of the spring 61. The inner end of the sliding rod 62 connected to the spring 61 is fixedly connected to the outer end of the fixing rod 64. The inner end of the fixing rod 64 is inserted into the radial opening groove 7 of the mating block 52. The outer end of the sliding rod 62, away from the fixing rod 64, passes through the side wall through hole of the mounting rod 4 and is fixedly connected to the sliding plate 63.

[0045] When the spindle body 11 needs to be removed for full oiling maintenance, the operator pulls the moving plate 63 outward along the radial direction of the spindle body. The moving plate 63 drives the sliding rod 62 to slide outward along the radial direction of the spindle body. The sliding rod 62 drives the fixing rod 64 to move outward along the radial direction of the spindle body. The inner end of the fixing rod 64 leaves the docking block 5. Then, the operator holds the spindle body 11 and moves it away from the circular plate 2 along its own axis. With the cooperation of the spindle stabilizing connection mechanism 12, the spindle body 11 can be separated from the mounting rod 4. Since the spindle body 11 and the mounting rod 4 are detachably connected, it is convenient to disassemble and assemble the spindle body 11 without the need for professional tools. It has the characteristics of saving time and effort and simple operation, which greatly improves the oiling maintenance time of the spindle body 11. In this embodiment, after the docking block 52 is inserted into the docking groove 51, the spindle body 11 is initially connected to the fixing rod 64. By setting the fixing component 6, the fixing rod 64 is inserted into the interior of the docking block 52 under the action of the spring 61, making it difficult for the spindle body 11 to fall off the fixing rod 64. By pulling the sliding plate 63, the sliding rod 62 can drive the fixing rod 64 to move. By opening a radial opening groove 7 inside the docking block 52, a first rubber pad 8 is installed in the fixing groove 7. The fixing rod 64 is inserted into the fixing groove 7 and contacts the first rubber pad 8. The first rubber pad 8 increases the friction, making the fixing rod 64 and the radial opening groove 7 more tightly connected.

[0046] refer to Figure 3 In order to avoid noise caused by direct contact between the sliding plate 63 and the fixed rod 64, a sound-absorbing pad 9 is fixedly connected to the inner surface of the sliding plate 63 facing the mounting rod 4 to fit the outer surface of the mounting rod 4; by setting the sound-absorbing pad 9, which is made of sponge material, noise is prevented from being caused by direct contact between the sliding plate and the fixed rod 64.

[0047] refer to Figure 4To ensure stable rotation of the spindle body 11 without hindering its assembly and disassembly, the spindle stabilizing connection mechanism 12 includes an outer tube 121 and an inner tube 123 that are interlocked and rotatably fitted together. The outer tube 121 is connected to the support bearing 3 via a side frame 10. The outer tube 121 is rotatably connected to the inner tube 123 via ball bearings 122. Several sets of radially extending and retractable radial limiting components 124 are connected to the inner wall of the inner tube 123. The inner ends of the radially limiting components 124 press against the outer wall of the spindle body 11 and are movably fitted with the spindle body 11. The cross-section of the clamping block 1242 is an arc-shaped structure adapted to the annular clamping groove 13. By setting up a stabilizing connection mechanism 12 and a radial limiting component 124, the spindle body 11 is connected to the inner tube 123. When the spindle body 11 rotates around its own central axis, the inner tube 123 rotates on the outer tube 121 through the ball bearings 122, which can stabilize the rotation of the spindle body 11. This structure does not affect the disassembly and assembly of the spindle body 11. By setting up the radial limiting component 124, when the spindle body 11 is disassembled and moved, the spindle body 11 squeezes the arc-shaped clamping block 1242. The clamping block 1242 moves under the action of the clamping spring 1241, and the spindle body 11 slowly separates from the clamping block 1242.

[0048] In some embodiments of the present invention, the spindle stabilizing mechanism of the present invention is provided with two sets of side frames 10, which are symmetrically arranged on both sides of the spindle body 11. The number of side frames 10 is not limited to two sets, but can also be three sets, four sets, etc., and each side frame 10 is arranged circumferentially around a confined space; the spindle stabilizing connecting mechanism 12 is disposed in the confined space, and the spindle body 11 is coaxially inserted in the spindle stabilizing connecting mechanism 12.

[0049] In some embodiments of the present invention, the side frame 10 is a U-shaped frame, one end of which is fixedly connected to the outer wall of the support bearing, and the other end is fixedly connected to the outer tube 121 of the stabilizing connecting mechanism 12.

[0050] In some embodiments of the present invention, the radial limiting component 124 includes a compression spring 1241, the compression spring 1241 being fixedly connected to the inner wall of the inner tube 123, and a compression block 1242 being fixedly connected to the inner end of the compression spring 1241, the compression block 1242 being inserted into the annular compression groove 13 of the spindle body 11.

[0051] refer to Figure 2To prevent the clamping block 1242 from sliding on the outer wall of the spindle body 11, an annular clamping groove 13 is provided circumferentially on the outer wall of the spindle body 11. A second rubber pad 14 is fixedly connected to the inner wall surface of the annular clamping groove 13. By providing an annular clamping groove 13 that matches the clamping block 1242 on one side of the spindle body 11, the clamping block 1242 is tightly fitted to the annular clamping groove 13 under the action of the clamping spring 1241, while the second rubber pad 14 increases the friction, making it difficult for the clamping block 1242 to slide within the annular clamping groove 13.

[0052] Operating principle and advantages: When the spindle body 11 needs to be removed for full oiling maintenance, the operator pulls the sliding plate 63 radially outward along the spindle body 11. The sliding plate 63 causes the sliding rod 62 to slide radially outward along the spindle body 11, which in turn causes the fixing rod 64 to move radially outward along the spindle body 11. The fixing rod 64 then moves radially outward away from the docking block 5. The operator then grasps the spindle body 11 and moves it to one side along its own axis. The annular clamping groove 13 on the spindle body 11 presses against the clamping block 1242. The clamping block 1242 moves radially under the action of the clamping spring 1241. Because the clamping block 1242 and the clamping groove 13 are arc-shaped surfaces, it facilitates the separation of the spindle body 11 from the inner tube 123 without the need for specialized tools. It features time-saving, labor-saving, and simple operation, greatly improving the oiling and maintenance time of the spindle body 11. When the spindle body 11 needs to be installed, pull the moving plate 63. When the moving plate moves, the fixed rod 64 connected to the sliding rod 62 moves. Then, insert the docking block 52 connected to one side of the spindle body 11 into the docking opening groove 51 of the mounting rod 4. Release the moving plate 63. Under the action of the spring 61, the fixed rod 64 is inserted into the radial opening groove 7 of the docking block 52 to fix the spindle body 11. When the clamping block 1242 is in contact with the second rubber pad 14 in the annular clamping groove 13, the spindle body 11 is connected to the inner tube 123. When the spindle body 11 rotates, the inner tube 123 rotates on the outer tube 121 through the ball bearing 122, which can make the spindle body 11 rotate stably.

[0053] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
