Description

Technical Field

[0001] This utility model belongs to textile machinery, specifically relating to a high-precision roller for ring spinning machines. Background Technology

[0002] As the spinning speed of ring spinning machines increases, the vibration generated by the rollers used in ring spinning machines during the operation of the main shaft has a greater impact on the equipment. Currently used rollers have end face runout of more than 0.3mm and radial runout of more than 0.15mm. During high-speed spinning, the vibration of the rollers on the equipment is becoming increasingly significant, which makes it easy for the rollers to accumulate yarn during operation. This not only increases the workload of cleaning the equipment, but also affects the operational stability of the rollers. Utility Model Content

[0003] The purpose of this invention is to provide a high-precision roller for ring spinning machines, which can reduce the vibration of the roller during high-speed spinning and reduce the impact of roller vibration on the spinning effect.

[0004] The technical solution of this utility model is as follows: a high-precision roller disc for a ring spinning machine is sleeved on the main shaft of the ring spinning machine. The high-precision roller disc includes a roller disc body, which includes an integrally formed inner ring, a connecting part, and an outer ring. A locking nut is threadedly connected to one side of the inner ring. An expansion sleeve is provided between the roller disc body and the main shaft of the ring spinning machine. The expansion sleeve is composed of an integrally formed fastening part and an abutting part. The fastening part of the expansion sleeve contacts the inner ring of the roller disc body. Several fastening slots are evenly opened on the fastening part. Both the fastening part and the abutting part of the expansion sleeve are conical structures. The large-diameter end of the fastening part is connected to the large-diameter end of the abutting part. The abutting part is located on the side where the inner ring is connected to the locking nut. An adjustment slot is opened on the abutting part.

[0005] Preferably, a plurality of reinforcing ribs are evenly provided on the connecting part of the roller body, and the two ends of the reinforcing ribs are respectively connected to the inner ring and the outer ring of the roller body.

[0006] Preferably, the connecting portion and the outer ring portion are connected by a circular arc transition.

[0007] Preferably, the adjustment slot on the abutment portion extends to the fastening portion, and the inner ring of the roller body contacts at least two fastening slots of the fastening portion.

[0008] The beneficial effects of this utility model are as follows: by gradually tightening the locking nut on the roller body, the expansion sleeve is gradually tightened on the main shaft. The fastening part and the abutment part of the conical structure prevent the roller body from moving. At the same time, the abutment part of the expansion sleeve abuts between the locking nut and the inner ring of the roller body. The abutment part between the locking nut and the expansion sleeve reduces the vibration of the roller body during the operation of the ring spinning machine, reduces the impact of the roller body vibration on the spinning effect during high-speed spinning of the ring spinning machine, and reduces the accumulation of yarn on the roller body during operation. Moreover, the high-precision roller can be removed from the ring spinning machine simply by loosening the locking nut on the roller body, which facilitates the maintenance and replacement of the high-precision roller.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0013] The rollers currently in use are increasingly affecting the vibration of the equipment during high-speed spinning, causing the rollers to accumulate yarn during operation. This not only increases the workload of cleaning the equipment but also affects the operational stability of the rollers. In view of this, this application provides a high-precision roller for ring spinning machines, which can reduce the vibration of the rollers during high-speed spinning and thus reduce the impact of roller vibration on the spinning effect.

[0014] like Figure 1-4 As shown, a high-precision roller of a ring spinning machine is fitted onto the main shaft 4 of the ring spinning machine. The high-precision roller includes a roller body 1, which includes an integrally formed inner ring 11, a connecting part 12, and an outer ring 13. A locking nut 2 is threadedly connected to one side of the inner ring 11. An expansion sleeve 3 is provided between the roller body 1 and the main shaft 4 of the ring spinning machine. The expansion sleeve 3 is composed of an integrally formed fastening part 31 and an abutment part 32. The fastening part 31 of the expansion sleeve 3 is in contact with the inner ring 11 of the roller body 1. Several fastening slots 33 are evenly opened on the fastening part 31. Both the fastening part 31 and the abutment part 32 of the expansion sleeve 3 are conical structures. The large diameter end of the fastening part 31 is connected to the large diameter end of the abutment part 32. The abutment part 32 is located on the side where the inner ring 11 is connected to the locking nut 2. An adjustment slot 34 is opened on the abutment part 32.

[0015] Based on the above embodiments, the locking nut 2 is screwed onto the inner ring 11 of the roller body 1, and the abutting part 32 of the expansion sleeve 3 is pressed against it between the inner ring 11 of the roller body 1 by the locking nut 2. At this time, the fastening part 31 of the expansion sleeve 3 contracts and locks the roller body 1 onto the main shaft 4 of the ring spinning machine.

[0016] In this embodiment, as Figure 1-2 As shown, a plurality of reinforcing ribs 14 are evenly arranged on the connecting part 12 of the roller body 1, and the two ends of the reinforcing ribs 14 are respectively connected to the inner ring part 11 and the outer ring part 13 of the roller body 1.

[0017] Specifically, the connecting part 12 and the outer ring part 13 are connected by a circular arc transition.

[0018] Based on the above embodiments, the strength of the roller body 1 is improved by reinforcing rib 14, and the inner ring portion 11 and outer ring portion 13 of the roller body 1 are connected by reinforcing rib 14, thereby reducing the weight of the roller body 1 and reducing the energy consumption of the ring spinning machine.

[0019] In this embodiment, the adjustment slot 34 on the abutment portion 32 of the expansion sleeve 3 extends to the fastening portion 31, and the inner ring portion 11 of the roller body 1 contacts at least two fastening slots 33 of the fastening portion 31.

[0020] Based on the above embodiments, by gradually tightening the locking nut 2 onto the roller body 1, the locking nut 2 gradually compresses the expansion sleeve 3, causing the diameter of the expansion sleeve 3 to gradually shrink through the adjustment groove 34 of the abutment part 32 and the fastening groove 33 of the fastening part 31, until the expansion sleeve 3 is tightly clamped onto the main shaft 4 of the ring spinning machine.

[0021] The working principle of this utility model is as follows: First, loosen the locking nut 2 connected to one side of the inner ring 11 in the roller body 1. At this time, there is a gap between the expansion sleeve 3 and the main shaft 4. The operator can install the expansion sleeve 3 and the roller body 1 onto the main shaft 4 and adjust the installation position of the expansion sleeve 3 and the roller body 1. After the installation position of the roller body 1 is adjusted, gradually tighten the locking nut 2 onto the roller body 1. The locking nut 2 gradually compresses the expansion sleeve 3, so that the expansion sleeve 3 gradually tightens onto the main shaft 4. At this time, the expansion sleeve 3... The fastening part 31 is fastened to the main shaft 4. The fastening part 31 with the conical structure and the abutment part 32 prevent the roller body 1 from moving. At the same time, the abutment part 32 of the expansion sleeve 3 abuts between the locking nut 2 and the inner ring part 11 of the roller body 1. The abutment part 32 of the locking nut 2 and the expansion sleeve 3 reduces the vibration of the roller body 1 when the ring spinning machine is running, reduces the impact of the vibration of the roller body 1 on the spinning effect when the ring spinning machine is spinning at high speed, and reduces the accumulation of yarn in the roller body 1 during operation. When the high-precision roller needs to be repaired or replaced, simply loosen the locking nut 2 on the roller body 1 to move the roller body 1 and the expansion sleeve 3 until the roller body 1, locking nut 2 and expansion sleeve 3 are removed from the main shaft 4 of the ring spinning machine. At this time, the high-precision roller can be repaired or a new high-precision roller can be replaced. The replaced high-precision roller can then be installed on the main shaft 4 of the ring spinning machine.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
