Description

Technical Field

[0001] The present application relates to the technical field of warping machines, and particularly to an axial fine-tuning mechanism for a pressure roller of a warping machine. Background Art

[0002] A warping machine is a device that draws yarn from bobbins on a creel and winds it parallelly and evenly around a warping beam at a specified length. During the warping process, in order to ensure the tightening force of the yarn winding, it is usually necessary to evenly press the surface of the yarn using a pressure roller.

[0003] However, since the lengths of pressure rollers produced by different manufacturers cannot be exactly the same, when the pressure roller is installed, there are deviations in the lengths of the two axial ends of the pressure roller installed inside the wall panels. Such installation deviations will cause the force-bearing points at both ends of the pressure roller to be unbalanced, making the pressure roller unable to rotate smoothly, resulting in uneven jumping amplitudes of the pressure roller, unable to generate a uniform pressing force on the yarn, and the yarn pressing effect of the pressure roller is poor, with obvious deficiencies. Utility Model Content

[0004] In order to improve the yarn pressing effect of the pressure roller, the present application provides an axial fine-tuning mechanism for a pressure roller of a warping machine.

[0005] The axial fine-tuning mechanism for a pressure roller of a warping machine provided by the present application adopts the following technical solution:

[0006] An axial fine-tuning mechanism for a pressure roller of a warping machine includes two relatively arranged wall panels. A pressure roller is rotatably connected between the two wall panels. Adjusting cylinders and fixed cylinders are respectively arranged on the opposite end faces of the two wall panels. The two ends of the pressure roller are respectively slidably arranged in the adjusting cylinder and the fixed cylinder. An adjusting component is arranged in the adjusting cylinder. The adjusting component includes an adjusting shaft rotatably connected inside the adjusting cylinder. A threaded section of the adjusting shaft is threadedly connected with an adjusting ring. A sliding sleeve is arranged in the adjusting cylinder. Sliding strips are arranged at both opposite ends of the sliding sleeve. A sliding groove slidably matched with the sliding strips is formed on the adjusting ring. The adjusting ring is slidably connected in the sliding sleeve. A connecting piece is arranged on the adjusting ring. The pressure roller is connected to the adjusting ring through the connecting piece.

[0007] By adopting the above technical solution, when the installation lengths of the two axial ends of the pressure roller are different, rotate the adjusting shaft. Under the sliding restriction of the sliding groove and the sliding strips, the rotation of the adjusting shaft drives the adjusting ring to move in the sliding sleeve. The adjusting ring drives the shaft end of the pressure roller to slide in the adjusting cylinder through the connection of the connecting piece. When the installation lengths of the two axial ends of the pressure roller are the same, stop rotating the adjusting shaft. The setting of the adjusting component realizes the adjustment of the axial installation distance of the pressure roller, reduces the possibility of large installation deviations at both axial ends of the pressure roller, thereby avoiding large-amplitude jumping during the rotation of the pressure roller, ensuring the uniform pressing of the pressure roller on the yarn, and improving the yarn pressing effect of the pressure roller.

[0008] Optionally, the connecting member is a snap ring, and a clamping groove is formed at one end of the pressure roller close to the adjusting cylinder, and the snap ring is clamped in the clamping groove.

[0009] By adopting the above technical solution, when the adjusting ring moves in the sliding sleeve, the adjusting ring drives the fixedly connected snap ring to move. Under the clamping cooperation of the snap ring in the clamping groove, the shaft end of the pressure roller is driven to move in the adjusting cylinder, so as to realize the adjustment of the axial installation distance of the pressure roller. When the pressure roller rotates, the snap ring rotates and fits in the clamping groove to ensure the normal operation of the pressure roller.

[0010] Optionally, a fixing ring is slidably connected in the fixing cylinder. Limiting blocks are arranged at both opposite ends of the fixing ring, and limiting grooves slidably matched with the limiting blocks are formed on the opposite inner side walls of the fixing cylinder. The fixing ring slides along the length direction of the fixing cylinder. A fixing groove is formed at one end of the pressure roller close to the fixing ring, and the surface of the fixing ring abuts in the fixing groove. A fixing component for fixing the fixing ring in the fixing cylinder is arranged in the fixing cylinder.

[0011] By adopting the above technical solution, during the process of the adjusting ring driving the shaft end of the pressure roller to move, the other end of the pressure roller drives the fixing ring to slide in the fixing cylinder. After the adjusting component is adjusted, the fixing component fixes the position of the fixing ring in the fixing cylinder. After the fixing ring is fixed, it cannot move, and at the same time, the shaft end of the pressure roller installed in the fixing cylinder cannot move either, so as to realize the fixation of the installation positions at both axial ends of the pressure roller, reduce the possibility of axial movement of the pressure roller during rotation, improve the stability of the pressure roller during rotation, and further improve the yarn pressing effect of the pressure roller.

[0012] Optionally, the fixing component includes a first screw rod and a second screw rod. The first screw rod and the second screw rod are respectively rotatably connected inside the opposite side walls of the fixing cylinder. A first clamping ring and a second clamping ring are slidably connected inside the fixing cylinder. One end of the first clamping ring is threadedly connected to the first screw rod, and the other end is slidably connected to the second screw rod. One end of the second clamping ring is threadedly connected to the second screw rod, and the other end is slidably connected to the first screw rod. When the fixing ring is fixed, the first clamping ring and the second clamping ring respectively abut against the opposite end faces of the fixing ring.

[0013] By adopting the above technical solution, after the adjustment component is adjusted, rotate the first screw rod. The rotation of the first screw rod drives the first clamping ring to gradually approach the fixed ring. When the first clamping ring is in close contact with the end face of the fixed ring, stop rotating the first screw rod and rotate the second screw rod. The second screw rod drives the second clamping ring to approach the fixed ring. When the second clamping ring is also in close contact with the end face of the fixed ring, the fixed ring is clamped and fixed in the inner cylinder of the fixed cylinder by the first clamping ring and the second clamping ring. The fixation of the fixed ring causes the fixed ring fixedly connected to the fixed ring to be fixed, thereby realizing the fixation of the installation positions at both axial ends of the pressure roller.

[0014] Optionally, both the fixed cylinder and the adjustment cylinder are detachably connected to the wall panel by connecting bolts.

[0015] By adopting the above technical solution, when a failure such as damage occurs to the adjustment component or the fixing component, the worker can replace the adjustment cylinder or the fixed cylinder by removing the connecting bolts to ensure the normal operation of the adjustment component and the fixing component.

[0016] Optionally, a copper sleeve is embedded on the surface of the sliding sleeve, and the outer surface of the adjustment ring abuts against the surface of the copper sleeve.

[0017] By adopting the above technical solution, the setting of the copper sleeve reduces the friction generated during the sliding process of the adjustment ring, enables the adjustment ring to slide smoothly in the sliding sleeve, and thus ensures the normal progress of the adjustment work.

[0018] Optionally, the copper sleeve is detachably connected to the sliding sleeve by the fixing bolt.

[0019] By adopting the above technical solution, when the surface of the copper sleeve is worn, the worker can replace the copper sleeve by removing the fixing bolt, reducing the possibility of the copper sleeve being damaged by burrs generated due to wear and thus further improving the stability of the adjustment process of the adjustment component.

[0020] Optionally, scale marks are provided at both axial ends of the pressure roller.

[0021] By adopting the above technical solution, the scale marks can enable the worker to more intuitively observe the installation lengths at both axial ends of the pressure roller, thereby facilitating the worker to adjust the axial installation position of the pressure roller through the adjustment component.

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

[0023] 1. By setting the adjustment component in the present application, the adjustment component realizes the adjustment of the axial installation distance of the pressure roller, reduces the possibility of large installation deviations at both axial ends of the pressure roller, thereby avoiding large fluctuations during the rotation of the pressure roller, ensuring the uniform pressing of the pressure roller on the yarn, and improving the yarn pressing effect of the pressure roller;

[0024] 2. This application fixes the installation positions at both axial ends of the pressure roller by setting a fixing component, reducing the possibility of axial movement of the pressure roller during rotation, improving the stability of the pressure roller during rotation, and further enhancing the yarn pressing effect of the pressure roller.

Detailed Description of the Embodiment

[0031] The following further elaborates on this application in conjunction with the attached Figures 1-5 for a more detailed description.

[0032] An embodiment of this application discloses an axial fine-tuning mechanism for a warping machine pressure roller.

[0033] Referring to Figure 1 and Figure 2 , an axial fine-tuning mechanism for a warping machine pressure roller includes two oppositely arranged wall panels 1, a pressure roller 2 is rotatably connected between the two wall panels 1, an adjusting cylinder 3 and a fixing cylinder 4 are respectively arranged on the end faces of the two wall panels 1 facing away from the pressure roller 2, both axial ends of the pressure roller 2 are slidably connected inside the adjusting cylinder 3 and the fixing cylinder, scale marks 21 are arranged at both axial ends of the pressure roller 2, an adjusting component 5 and a fixing component 6 are respectively arranged inside the adjusting cylinder 3 and the installation cylinder, the adjusting component 5 is used to adjust the axial installation position of the pressure roller 2, and the fixing component 6 is used to fix the axial installation position of the pressure roller 2.

[0034] When installing the pressure roller 2, the worker installs the two axial ends of the pressure roller 2 inside the adjusting cylinder 3 and the fixed cylinder 4 respectively. Subsequently, the position of the end of the pressure roller 2 inside the adjusting cylinder 3 is adjusted through the adjusting assembly 5. When the worker observes through the scale mark 21 that the lengths of the two axial ends of the pressure roller 2 extending into the adjusting cylinder 3 and the fixed cylinder 4 are the same, the fixing assembly 6 is activated to fix the installation position of the pressure roller 2. At this time, the installation positions of the two axial ends of the pressure roller 2 are the same. Subsequently, the worker rotates the pressure roller 2 to compact the yarn.

[0035] Refer to Figure 1 , mounting plates (not shown in the figure) are fixedly connected to the outer surfaces of the fixed cylinder 4 and the adjusting cylinder 3. A plurality of connecting bolts 101 are circumferentially and evenly distributed on the surface of each mounting plate. In this embodiment, the number of the connecting bolts 101 is four, and the mounting plate is detachably connected to the wall panel 1 through the connecting bolts 101.

[0036] When the adjusting assembly 5 inside the adjusting cylinder 3 or the fixing assembly 6 inside the fixed cylinder 4 is damaged or fails, the worker can replace the adjusting cylinder 3 or the fixed cylinder 4 by removing the connecting bolts 101 to ensure the normal operation of the adjusting assembly 5 and the fixing assembly 6.

[0037] Refer to Figure 2 and Figure 3 , the adjusting assembly 5 includes an adjusting shaft 51 rotatably connected inside the adjusting cylinder 3. One end of the adjusting shaft 51 close to the pressure roller 2 is a threaded section. An adjusting ring 52 is threadedly connected to the threaded section of the adjusting shaft 51. A sliding sleeve 53 is fixedly installed inside the adjusting cylinder 3. Both opposite ends of the sliding sleeve 53 are fixedly connected with sliding bars 54. The length direction of the sliding bars 54 is parallel to the length direction of the sliding sleeve 53. The adjusting ring 52 is provided with sliding grooves 521 corresponding to the sliding bars 54 one by one. The sliding bars 54 are slidably connected inside the corresponding sliding grooves 521. The surface of the adjusting ring 52 facing the axial end of the pressure roller 2 is fixedly connected with a clamping ring 551. A clamping groove 22 is opened at one end of the pressure roller 2 close to the adjusting cylinder 3. The clamping ring 551 is clamped inside the clamping groove 22. When the pressure roller 2 rotates, the clamping ring 551 rotates in cooperation with the clamping groove 22. One end of the adjusting shaft 51 far from the pressure roller 2 is fixedly connected with a synchronous pulley (not shown in the figure). In this embodiment, the adjusting shaft 51 is driven to rotate through the transmission of a motor, synchronous pulleys and a synchronous belt.

[0038] After the pressure roller 2 is installed on the brackets of the two wall panels 1, the worker observes the axial installation lengths at both ends of the pressure roller 2 through the scale marks 21. If the scale marks 21 are inconsistent, the adjusting shaft 51 is driven to rotate. Under the limitation of the sliding directions of the sliding groove 521 and the sliding bar 54, the rotation of the adjusting shaft 51 drives the adjusting ring 52 threadedly connected to the threaded section to move within the sliding sleeve 53. The movement of the adjusting ring 52 drives the fixedly connected snap ring 551 to move. Under the snap-fit of the snap ring 551 in the snap groove 22, the shaft end of the pressure roller 2 is driven to move within the adjusting cylinder 3, thereby realizing the adjustment of the axial installation distance of the pressure roller 2. When the scale marks 21 at both axial ends of the pressure roller 2 are the same, stop rotating the adjusting shaft 51. Such a setting reduces the possibility of large installation deviations at both axial ends of the pressure roller 2, avoids large fluctuations during the rotation of the pressure roller 2, thereby ensuring the uniform pressing of the yarn by the pressure roller 2 and improving the yarn pressing effect of the pressure roller 2.

[0039] Refer to Figure 2 and Figure 3 , a copper sleeve 7 is embedded on the sliding sleeve 53. The copper sleeve 7 is detachably connected to the sliding sleeve 53 through a fixing bolt 71. The outer surface of the adjusting ring 52 abuts against the surface of the copper sleeve 7. The setting of the copper sleeve 7 effectively reduces the friction generated during the sliding of the adjusting ring 52, enabling the adjusting ring 52 to slide smoothly within the sliding sleeve 53. At the same time, when the surface of the copper sleeve 7 is worn, the worker can replace the copper sleeve 7 by removing the fixing bolt 71 to ensure the smooth sliding of the adjusting ring 52.

[0040] Refer to Figure 4 and Figure 5 , a fixing ring 8 is slidably connected to the fixing cylinder 4. Both opposite ends of the fixing ring 8 are fixedly connected with limiting blocks 81. Limiting grooves 41 that are slidably matched with the limiting blocks 81 are formed on the side walls at both opposite ends of the fixing cylinder 4. Under the limitation of the limiting blocks 81 and the limiting grooves 41, the fixing ring 8 can only slide along the length direction of the fixing cylinder 4. A fixing groove 23 is formed on the shaft body of the pressure roller 2 extending into the fixing cylinder 4. The inner ring surface of the fixing ring 8 abuts against the inner side wall of the fixing groove 23.

[0041] Refer to Figure 4 and Figure 5, the fixing component 6 includes a first screw rod 61 and a second screw rod 62. The length directions of the first screw rod 61 and the second screw rod 62 are parallel to the fixing cylinder 4. The first screw rod 61 and the second screw rod 62 are respectively rotatably connected inside the opposite side walls of the fixing cylinder 4. A first clamping ring 63 and a second clamping ring 64 are slidably connected inside the fixing cylinder 4. The first clamping ring 63 and the second clamping ring 64 are respectively arranged at two ends of the fixing ring 8. One end of the first clamping ring 63 is threadedly connected to the first screw rod 61, and the other end is slidably connected to the second screw rod 62. One end of the second clamping ring 64 is threadedly connected to the second screw rod 62, and the other end is slidably connected to the first screw rod 61. When the fixing ring 8 is fixed by the fixing component 6, the two opposite end faces of the fixing ring 8 are respectively in close contact with the first clamping ring 63 and the second clamping ring 64. Handwheels (not shown in the figure) are fixedly connected to the ends of the first screw rod 61 and the second screw rod 62 far away from the wall panel 1.

[0042] When the scale marks 21 at both axial ends of the pressure roller 2 are the same, the worker first rotates the first screw rod 61. The rotation of the first screw rod 61 drives the first clamping ring 63 to gradually approach the fixing ring 8. When the first clamping ring 63 is in close contact with the end face of the fixing ring 8, stop rotating the first screw rod 61 and rotate the second screw rod 62. The second screw rod 62 drives the second clamping ring 64 to approach the fixing ring 8. When the second clamping ring 64 is also in close contact with the end face of the fixing ring 8, at this time, the fixing ring 8 is clamped and fixed in the fixing cylinder 4 by the first clamping ring 63 and the second clamping ring 64. After the fixing ring 8 is fixed, it cannot move, so that the pressure roller 2 connected to the fixing ring 8 through the fixing groove 23 also cannot move, thereby realizing the fixation of the installation positions at both axial ends of the pressure roller 2. At the same time, it reduces the possibility of axial movement of the pressure roller 2 during rotation, improves the stability of the pressure roller 2 during rotation, and improves the yarn pressing effect of the pressure roller 2.

[0043] The implementation principle of the axial fine-tuning mechanism for the pressure roller of the warping machine in the embodiment of the present application is as follows: When the installation lengths at both axial ends of the pressure roller 2 are different, rotate the adjusting shaft 51. The rotation of the adjusting shaft 51 drives the adjusting ring 52 to move inside the sliding sleeve 53. The movement of the adjusting ring 52 drives the clamping ring 551 to move. The clamping ring 551 drives the shaft end of the pressure roller 2 to move inside the adjusting cylinder 3. When the installation lengths at both axial ends of the pressure roller 2 are the same, stop rotating the adjusting shaft 51. The movement of the clamping ring 551 drives the shaft end of the pressure roller 2 to slide inside the adjusting cylinder 3 through the connection of the connecting member 55, thereby realizing the adjustment of the axial installation distance of the pressure roller 2. When the scale marks 21 at both axial ends of the pressure roller 2 are the same, stop rotating the adjusting shaft 51. The setting of the adjusting component 5 realizes the adjustment of the installation positions at both axial ends of the pressure roller 2, reduces the possibility of large installation deviations at both axial ends of the pressure roller 2, thereby avoiding large fluctuations during the rotation of the pressure roller 2, ensuring the uniform pressing of the yarn by the pressure roller 2, and improving the yarn pressing effect of the pressure roller 2.

[0044] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
