Description

Technical Field

[0001] The utility model relates to the technical field of textile production, in particular to an alignment device. Background Art

[0002] In the textile industry, a comber is usually used to remove short fibers and impurities in raw cotton or other raw materials, and arrange the selected high-quality fibers to improve the parallelism of the fibers. Finally, the fibers are conveyed into a sliver can.

[0003] In the actual working environment, in order to effectively wind the carded sliver onto the sliver can, a rotating device is usually provided at the bottom of the sliver can to drive the sliver can to rotate. During the rotation of the sliver can, a plurality of alignment arms are distributed around the sliver can to position and support the sliver can. In the actual use process, the friction between the inner wall of the barrel wheel on the alignment arm and the positioning shaft is large. After long-term use of the alignment arm, the barrel wheel will be severely worn, resulting in insensitive rotation of the barrel wheel, and even causing the sliver can to be misaligned or run out, thus affecting the fiber forming quality in the can. Therefore, this application specifically proposes an alignment device that reduces wear during work. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide an alignment device that reduces wear during work.

[0005] To achieve the above purpose, the utility model provides an alignment device, including:

[0006] A plurality of alignment arm assemblies are circumferentially distributed around the sliver can. Each alignment arm assembly includes a first positioning rod vertically arranged on one side of the sliver can. A connecting member is arranged on the side of the first positioning rod close to the sliver can. A second positioning rod is vertically arranged at the end of the connecting member close to the sliver can. A bearing is sleeved on the second positioning rod, and a barrel wheel is sleeved on the bearing. The outer wall of the barrel wheel contacts the outer wall of the sliver can. When the sliver can rotates, the barrel wheel drives the outer ring of the bearing to rotate with the second positioning rod as the rotation center.

[0007] Further, the top end of the second positioning rod extends out of the bearing and is provided with a double-thread, and a guide rod is also vertically arranged at the top of the barrel wheel;

[0008] A transmission component is provided on the second positioning rod. The transmission component includes a moving ring that is screwed with the double-thread of the second positioning rod, and the guiding rod passes through the moving ring. When the barrel wheel rotates, the barrel wheel drives the moving ring to reciprocate up and down on the second positioning rod through the guiding rod. A first abutting ring is arranged at the bottom end of the moving ring. A lubricating component is also provided on the second positioning rod, and the lubricating component is arranged between the moving ring and the bearing and below the double-thread. When the moving ring descends, the moving ring drives the first abutting ring to move downward and press the lubricating component, so that the lubricating component lubricates the bearing.

[0009] Further, the lubricating component includes an oil storage ring sleeved on the second positioning rod. A chamber for storing a lubricating medium is opened in the oil storage ring, and the oil storage ring is arranged above the bearing. A plurality of oil outlet nozzles are distributed on the bottom surface of the oil storage ring, and each oil outlet nozzle is aligned with the moving position of the outer ring of the bearing. An extrusion member is also arranged in the oil storage ring, and the extrusion member is used for extruding the lubricating medium in the oil storage ring.

[0010] Further, the extrusion member includes a second abutting ring vertically and slidably inserted on the top surface of the oil storage ring. The top surface of the second abutting ring extends out of the oil storage ring and corresponds to the first abutting ring. The bottom surface of the second abutting ring is inserted into the inner cavity of the oil storage ring and is provided with a compression ring. The compression ring is vertically and slidably arranged in the inner cavity of the oil storage ring, and the compression ring is in dynamic sealing fit with the inner cavity of the oil storage ring. A plurality of through holes for the lubricating medium to pass through are distributed on the compression ring. A plurality of first elastic units are distributed between the compression ring and the bottom surface of the inner cavity of the oil storage ring, and each first elastic unit provides an upward thrust for the compression ring. When the first abutting ring extrudes the second abutting ring, the second abutting ring drives the compression ring to move downward in the inner cavity of the oil storage ring and extrude the lubricating medium.

[0011] Further, the connecting component includes a multi-stage telescopic member arranged on the surface of the first positioning rod close to the strip barrel. The multi-stage telescopic member includes a plurality of sliding sleeves sequentially sleeved from the first positioning rod towards the strip barrel. A second elastic unit is arranged between each sliding sleeve, and the second elastic unit provides a thrust for the corresponding sliding sleeve towards the center direction of the strip barrel. A connecting rod is also slidably arranged in the sliding sleeve close to the strip barrel end. A third elastic unit is arranged between the connecting rod and the corresponding sliding sleeve, and the second positioning rod is vertically arranged at the end of the connecting rod close to the strip barrel. The third elastic unit provides a thrust for the connecting rod towards the center direction of the strip barrel. A limiting ring is also arranged on the connecting rod, and the limiting ring is arranged between the corresponding sliding sleeve and the barrel wheel.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0021] Refer to Figures 1-4 .

[0022] The present utility model discloses a centering device, including:

[0023] Multiple centering arm components are circumferentially distributed around the bale bin 8. Each centering arm component includes a first positioning rod 1 vertically arranged on one side of the bale bin 8. A connecting component 2 is arranged on the side of the first positioning rod 1 close to the bale bin 8. A second positioning rod 3 is vertically arranged at one end of the connecting component 2 close to the bale bin 8. A bearing 4 is sleeved on the second positioning rod 3. A barrel wheel 5 is sleeved on the bearing 4. The outer wall of the barrel wheel 5 contacts the outer wall of the bale bin 8. When the bale bin 8 rotates, the barrel wheel 5 drives the outer ring of the bearing 4 to rotate with the second positioning rod 3 as the rotation center.

[0024] In specific implementation, when the bale bin 8 rotates, the bale bin 8 drives each barrel wheel 5 to rotate. Each barrel wheel 5 drives the outer ring of the corresponding bearing 4 to rotate with the second positioning rod 3 as the rotation center, and prevents the bale bin 8 from deviating or even accidentally disengaging from the rotating device when rotating.

[0025] In this utility model, through the cooperation between the barrel wheel 5 and the bearing 4, when the bale bin 8 drives each barrel wheel 5 to rotate, the inner wall of each barrel wheel 5 does not directly rub against the second positioning rod 3. The inner ring of the bearing 4 is used to contact the second positioning rod 3 instead of the barrel wheel 5 and rotates through the outer ring of the bearing 4, reducing the wear of the barrel wheel 5, thereby stabilizing the bale bin 8 to ensure the fiber forming quality in the barrel.

[0026] In an embodiment, the top end of the second positioning rod 3 extends out of the bearing 4 and is provided with a double-thread. A guide rod 51 is also vertically arranged at the top of the barrel wheel 5;

[0027] A transmission component 6 is arranged on the second positioning rod 3. The transmission component 6 includes a moving ring 61 screwed with the double-thread of the second positioning rod 3, and the guide rod 51 passes through the moving ring 61. When the barrel wheel 5 rotates, the barrel wheel 5 drives the moving ring 61 to reciprocate up and down on the second positioning rod 3 through the guide rod 51. A first abutting ring 62 is arranged at the bottom end of the moving ring 61. A lubricating component 7 is also arranged on the second positioning rod 3, and the lubricating component 7 is arranged between the moving ring 61 and the bearing 4 and below the double-thread. When the moving ring 61 descends, the moving ring 61 drives the first abutting ring 62 to move downward and press the lubricating component 7, so that the lubricating component 7 lubricates the bearing 4.

[0028] With such a design, when the barrel 8 drives the barrel wheels 5 to rotate, each barrel wheel 5 drives the moving ring 61 to rotate together on the double-thread of the second positioning rod 3 through the corresponding guide rod 51. At this time, the moving ring 61 drives the first abutting ring 62 to descend until the first abutting ring 62 is connected to the lubricating component 7, and the lubricating component 7 lubricates the bearing 4. When the moving ring 61 moves to the bottom end of the double-thread, as the barrel wheel 5 continues to rotate, the moving ring 61 drives the first abutting ring 62 to ascend and separate from the lubricating component 7. At this time, the lubricating component 7 stops lubricating the bearing 4 until the first abutting ring 62 descends again and is connected to the lubricating component 7, thereby realizing periodic lubrication of the bearing 4 and preventing excessive wear of the bearing 4.

[0029] It should be noted that a plurality of guide rods 51 can be arranged on the barrel wheel 5 and all are inserted through the moving ring 61, so as to further ensure the stability of the moving ring 61 when moving up and down.

[0030] In an embodiment, the lubricating component 7 includes an oil storage ring 71 sleeved on the second positioning rod 3. A chamber for storing lubricating medium is provided in the oil storage ring 71, and the oil storage ring 71 is arranged above the bearing 4. A plurality of oil nozzles 72 are distributed on the bottom surface of the oil storage ring 71, and each oil nozzle 72 is aligned with the moving part of the outer ring of the bearing 4. An extrusion member 73 is also arranged in the oil storage ring 71, and the extrusion member 73 is used to extrude the lubricating medium in the oil storage ring 71.

[0031] With such a design, when the barrel wheel 5 rotates, the moving ring 61 drives the first abutting ring 62 to descend and abut against the extrusion member 73. As the first abutting ring 62 continues to descend, the first abutting ring 62 applies a downward pressure to the extrusion member 73 to make the extrusion member 73 extrude the lubricating medium in the oil storage ring 71. The lubricating medium flows out through each oil nozzle 72 and drips onto the moving part of the outer ring of the bearing 4 to realize lubrication of the bearing 4. When the first abutting ring 62 ascends and leaves the extrusion member 73, at this time the extrusion member 73 no longer extrudes the oil storage ring 71, and the oil storage ring 71 stops lubricating.

[0032] Preferably, the lubricating medium can be lubricating oil.

[0033] It should be noted that one-way valves opening towards the bearing 4 can be arranged in each oil nozzle 72. Only when the lubricating medium is extruded, each one-way valve opens and the lubricating medium flows out of the oil storage ring 71. And the structure and function of the one-way valve are common knowledge in the related field, so the structure thereof will not be described in detail here.

[0034] In one embodiment, the extrusion member 73 includes a second abutting ring 731 vertically and slidably inserted on the top surface of the oil storage ring 71. The top surface of the second abutting ring 731 extends out of the oil storage ring 71 and corresponds to the first abutting ring 62. The bottom surface of the second abutting ring 731 is inserted into the inner cavity of the oil storage ring 71 and is provided with a compression ring 732. The compression ring 732 is vertically and slidably arranged in the inner cavity of the oil storage ring 71, and the compression ring 732 is in dynamic sealing cooperation with the oil storage ring 71. A plurality of through holes 7321 for the lubricating medium to pass through are distributed on the compression ring 732. A plurality of first elastic units 733 are distributed between the bottom surface of the inner cavity of the compression ring 732 and the oil storage ring 71. Each first elastic unit 733 provides an upward thrust for the compression ring 732. When the first abutting ring 62 extrudes the second abutting ring 731, the second abutting ring 731 drives the compression ring 732 to move downward in the inner cavity of the oil storage ring 71 and extrudes the lubricating medium.

[0035] With such a design, when the moving ring 61 moves downward, the moving ring 61 drives the first abutting ring 62 to move together and makes the bottom surface of the first abutting ring 62 abut against the top surface of the second abutting ring 731. As the moving ring 61 continues to move downward, the first abutting ring 62 exerts a downward pressure on the compression ring 732 through the second abutting ring 731. The compression ring 732 extrudes the lubricating medium, and part of the lubricating medium flows out of the oil storage ring 71 through each oil outlet 72. The remaining lubricating medium flows into the space between the compression ring 732 and the top surface of the inner cavity of the oil storage ring 71 through each through hole 7321, avoiding excessive discharge of the lubricating medium and ensuring that the lubricating medium in the oil storage ring 71 can lubricate the bearing 4 multiple times. At this time, each first elastic unit 733 is compressed. When the moving ring 61 drives the first abutting ring 62 to rise, the first abutting ring 62 no longer exerts a downward pressure on the second abutting ring 731. The first elastic unit 733 loses restraint and drives the compression ring 732 to rise. The compression ring 732 no longer extrudes the lubricating medium, and the lubricating medium in the space between the compression ring 732 and the top surface of the inner cavity of the oil storage ring 71 flows back to the space between the compression ring 732 and the bottom surface of the inner cavity of the oil storage ring 71 as the compression ring 732 rises.

[0036] Preferably, the first elastic unit 733 can adopt a spring in the prior art

[0037] In one embodiment, the connecting member 2 includes a multi-stage telescopic member 21 disposed on one surface of the first positioning rod 1 close to the bale 8. The multi-stage telescopic member 21 includes a plurality of sliding sleeves 211 slidably sleeved in sequence from the first positioning rod 1 towards the bale 8. A second elastic unit 212 is provided between the sliding sleeves 211. The second elastic unit 212 provides a thrust force for the corresponding sliding sleeve 211 towards the center of the bale 8. A connecting rod 22 is further slidably disposed in the sliding sleeve 211 at one end close to the bale 8. A third elastic unit 23 is provided between the connecting rod 22 and the corresponding sliding sleeve 211, and the second positioning rod 3 is vertically disposed at one end of the connecting rod 22 close to the bale 8. The third elastic unit 23 provides a thrust force for the connecting rod 22 towards the center of the bale 8. A limiting ring 221 is further provided on the connecting rod 22. The limiting ring 221 is disposed between the corresponding sliding sleeve 211 and the barrel wheel 5. The limiting ring 221 is used to limit the contraction amount of the connecting rod 22.

[0038] With such a design, after the bale 8 is placed in a suitable position, each second elastic unit 212 applies a thrust force towards the center of the bale 8 to the corresponding sliding sleeve 211, and the third elastic unit 23 applies a thrust force towards the center of the bale 8 to the corresponding second positioning rod 3 through the connecting rod 22, so that the barrel wheel 5 is closely attached to the outer wall of the bale 8. When the specification of the bale 8 is changed, each multi-stage telescopic member 21 and the connecting rod 22 will contract according to the diameter of the bale 8 and make the barrel wheel 5 always closely attached to the outer wall of the bale 8, so that the barrel wheel 5 can adapt to bales 8 with different diameters. When the connecting rod 22 contracts into the corresponding sliding sleeve 211, the limiting ring 221 will abut against the sliding sleeve 211 to prevent the connecting rod 22 from continuing to contract, thus avoiding the influence of the sliding sleeve 211 on the rotation of the barrel wheel 5.

[0039] Preferably, the second elastic unit 212 and the third elastic unit 23 can adopt springs in the prior art.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. In addition, "a plurality of", "multiple groups", and "several" mean more than two.
