Description

Technical Field

[0001] This utility model relates to the field of roving frame technology, specifically to a high-strength roving frame roller. Background Technology

[0002] The roving frame is the core spinning equipment that processes fiber slivers into rovings. Its core technologies include automated doffing and multi-motor synchronous control. The doffing time for the entire row is short, and the equipment supports pure or blended spinning of carded cotton, combed cotton, and chemical fibers under 65 mm.

[0003] Currently, when existing rollers malfunction and require repair or replacement, multiple parts of the structure need to be dismantled, making repairs inconvenient. Furthermore, when the rubber sleeves wear out and need replacement, the entire roller rod must be dismantled, which severely impacts work efficiency. Therefore, there is an urgent need for a high-strength roller for roving machines to improve these issues. Utility Model Content

The limiting frame 8 is engaged at the top of the support frame 5. The limiting rod 11 is fixedly connected to the support frame 5. In this embodiment, the auxiliary hole 10 serves to install the fixing bolt 7. The fixing bolt 7 serves to fix the limiting frame 8 to the top of the support frame 5.

[0036] Reference Figure 4 , Figure 5 and Figure 6The friction device 4 includes a positioning hole 16, a positioning shaft 17 is provided inside the positioning hole 16, an installation cylinder 18 is provided at one end of the positioning shaft 17, a guide hole 19 is provided inside the installation cylinder 18, a guide rod 20 is provided on one side of the installation cylinder 18, a rubber sleeve 21 and a fixing cylinder 22 are provided on the outside of the installation cylinder 18, an internal thread 23 is provided on the outside of the installation cylinder 18, and an external thread 24 is provided inside the fixing cylinder 22. In this embodiment, the positioning hole 16 plays a limiting role, and the positioning shaft 17 plays a role in preventing the installation cylinder 18 from becoming loose.

[0037] Reference Figure 4 , Figure 5 and Figure 6 The positioning hole 16 is opened inside the roller rod A2 and is adapted to the positioning shaft 17. The mounting cylinder 18 is snapped onto the outside of the roller rod A2. The guide rod 20 is adapted to the guide hole 19. In this embodiment, the guide rod 20 plays a limiting role, and the guide hole 19 plays a role in snapping onto the guide rod 20.

[0038] Reference Figure 6 The rubber sleeve 21 is fixedly connected to the outside of the mounting cylinder 18, and the internal thread 23 is adapted to the external thread 24. The fixed cylinder 22 is threadedly connected to both ends of the mounting cylinder 18. In this embodiment, the rubber sleeve 21 plays the role of increasing friction.

[0039] Reference Figure 1 Roller rod A2 is provided with roller rod B25 and roller rod C26 on its outer side, and roller rod D27 is provided on one side of roller rod C26. In this embodiment, roller rod A2 plays a transmission role, and roller rod B25, roller rod C26, roller rod D27 have the same function as roller rod A2.

[0040] The implementation principle of this embodiment is as follows:

[0041] When roller rod A2 (or roller rod B25, roller rod D27) malfunctions and needs to be replaced or repaired, the operator needs to use tools to rotate the fixing bolt 7. After removing the fixing bolt 7, pull it out from the mounting hole 6 and auxiliary hole 10. After pulling out the fixing bolt 7, push the limit frame 8 upward. As the limit frame 8 moves upward, it will slide on the outside of the limit rod 11. After the limit frame 8 is separated from the support frame 5, the operator will push the protective shell 12 upward. The protective shell 12 has an adapter hole 15 inside, which is adapted to the limit rod 11. Therefore, during the process of pushing the protective shell 12 upward, the protective shell 12 will slide on the outside of the limit frame 8 until the protective shell 12 loses connection with the limit rod 11. At this time, the roller rod A2 will be unrestricted and can be taken out upward for repair or replacement.

[0042] After repairing or replacing roller A2, when installing roller A2 into the support frame 5, first apply grease to the inside of the protective shell 12, ensuring the grease is evenly distributed and covers the connecting shaft 13 and roller 14. After applying the grease, first snap the protective shell 12 onto the outside of roller A2. Then align the adapter hole 15 with the limiting rod 11, allowing the limiting rod 11 to be inserted into the auxiliary hole 10. After entering the interior, push the protective shell 12 downwards until the protective shell 12 can no longer move downwards. Then install the limit bracket 8 on the top of the support key. During the installation of the limit bracket 8, the limit hole 9 needs to be aligned with the limit rod 11. The limit rod 11 can pass through the limit hole 9 until the limit bracket 8 can no longer move downwards. At this time, the mounting hole 6 and the auxiliary hole 10 will be concentric. The staff needs to install the fixing bolt 7 into the interior of the auxiliary hole 10 and the mounting hole 6, and use tools to tighten it to complete the fixing of the roller rod A2.

[0043] During the operation of the roving frame, rollers A2, B25, and D27 are all in normal condition. If the rubber sleeve 21 is severely worn and affects normal operation, it needs to be replaced. The operator uses a tool to rotate the fixed cylinder 22. The fixed cylinder 22 and the mounting cylinder 18 are connected by external thread 24 and internal thread 23. During the rotation of the fixed cylinder 22, the positioning shaft 17 is engaged inside the positioning hole 16, so the mounting cylinder 18 will not rotate with the fixed cylinder 22. Therefore, the mounting cylinder 18 can be quickly separated from the fixed cylinder 22. After the fixed cylinder 22 and the mounting cylinder 18 are separated, the mounting cylinder 18 is pried open with a tool to separate it from the left and right. During this process, the positioning shaft 17 will be pulled out from inside the positioning hole 16, and the guide hole 19 will also be pulled out from inside the guide hole 19 until the mounting cylinder 18 is split in two. At this time, the fixed cylinder 22 is still engaged on the outside of the roller A2.

[0044] After replacing the mounting sleeve 18 and the rubber sleeve 21, align the positioning shaft 17 with the positioning hole 16 and insert the positioning shaft 17 into the positioning hole 16. After both mounting sleeves 18 are engaged with the outside of the roller rod A2, the positioning shaft 17 will be fully inserted into the positioning hole 16. At the same time, the guide rod 20 will also be inserted into the guide hole 19 to limit the movement. Then, the worker pushes the fixing sleeve 22 towards the mounting sleeve 18. After the fixing sleeve 22 contacts the mounting sleeve 18, rotate the fixing sleeve. Through the cooperation between the external thread 24 and the internal thread 23, the fixing sleeve 22 is engaged with the outside of the mounting sleeve 18. Thus, the replacement of the rubber sleeve 21 can be completed quickly.

[0045] When repairing or replacing roller rod A2 or roller rod B25, roller rod B25, or roller rod D27, it is necessary to first disconnect them from the internal structure of gearbox 1. The external structures of roller rods A2, B25, and D27 are all the same. The diameter of roller rod A2 before modification was 30 mm, and the diameter after modification is 32 mm. The diameter of roller rod B25 before modification was 25 mm, and the diameter after modification is 26 mm. The diameter of roller rod C26 before modification was 24 mm, and the diameter after modification is 25 mm. The diameter of roller rod D27 before modification was 27 mm, and the diameter after modification is 29 mm.
