Description

Rubber tube vulcanization support device TECHNICAL FIELD

[0001] The present application belongs to the technical field of pipeline manufacturing, and particularly relates to a rubber tube vulcanization support device. BACKGROUND

[0002] At present, when rubber flat hoses are vulcanized, steam is introduced from one end of the hose, steam is discharged from the other end of the hose, steam flows in the pipeline, and under a certain steam pressure, the rubber flat hose reaches a certain temperature, and after a period of time, the raw rubber in the flat hose is vulcanized into mature rubber. During the entire vulcanization process, a large amount of condensed water is generated due to the steam, which accumulates below the rubber flat hose, causing the hose below to be tightly attached to the support under the action of gravity. The rubber is relatively sticky before it is fully vulcanized, so after the vulcanization starts, the rubber hose surface and the support will be bonded together at the same contact point within a period of time, affecting the product quality. At present, the rubber flat hose is moved to another contact position by manpower at intervals before vulcanization to ensure that the hose surface contact surface is not at the same position, which can reduce the adhesion of the hose and the support. Due to the high temperature of the rubber flat hose surface during vulcanization and the poor space environment, the personnel operation work intensity is high, and the product quality cannot be effectively guaranteed. Especially for the vulcanization process of large pipes, the quality is large, the length is long, and the product quality cannot be effectively guaranteed. SUMMARY

[0006] In one embodiment, the lifting mechanism comprises a driving unit, the driving unit is arranged at both ends of the support roller, the driving unit comprises a driving shaft and an eccentric wheel arranged on the driving shaft, and the support roller is supported at both ends of the eccentric wheel.

[0007] In one embodiment, the support roller comprises a mounting shaft and a roller body rotatably arranged on the mounting shaft, the mounting shaft protrudes from the roller body at both ends, and is supported on the eccentric wheel.

[0008] In one embodiment, a limiting mechanism is further included, which comprises a limiting plate and a limiting notch provided on the limiting plate, and the mounting shaft is supported on the eccentric wheel after passing through the limiting notch.

[0026] The application will be further described below in conjunction with specific embodiments. Obviously, the described embodiments are only some of the embodiments of the application, but not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without making creative changes belong to the protection scope of the application.

[0027] The technical scheme adopted by the application is as follows: as shown in FIGS. 1 and 3, a rubber tube 100 vulcanization support device includes a support roller 1, a plurality of support rollers 1 are arranged along the length direction of the rubber tube 100 and used for supporting the rubber tube 100; and a lifting mechanism used for driving the plurality of support rollers 1 to alternately lift. In the rubber tube 100 vulcanization process, the plurality of support rollers 1 can be controlled to alternately lift by the lifting mechanism, so that the support rollers 1 at different positions alternately support the rubber tube 100, and the problem of adhesion caused by long-time contact of the same position with the support roller 1 is avoided, and the structure is simple and effective. As can be seen from FIGS. 1 to 4, the support roller 1 at the same position is at different positions.

[0028] As shown in FIGS. 1 to 8, in some embodiments, the lifting mechanism includes a drive unit, the drive unit is arranged at both ends of the support roller 1, the drive unit includes a drive shaft 2 and an eccentric wheel 3 arranged on the drive shaft 2, and the support roller 1 is supported on the eccentric wheel 3 at both ends. That is, two drive units are included, the drive shafts 2 of the two drive units are arranged at both sides of the support roller 1 respectively, the two drive shafts 2 synchronously rotate to drive the support roller 1 to ascend or descend, one of the drive shafts 2 can be directly connected with a drive mechanism 5 and connected with the other drive shaft 2 through a sprocket 51 and a chain transmission to realize synchronous rotation, as shown in FIG. 5.

[0029] Specifically, as shown in FIGS. 6 to 8, in some embodiments, the support roller 1 includes a mounting shaft 11 and a roller body 12 rotatably arranged on the mounting shaft 11, and the mounting shaft 11 protrudes from the roller body 12 at both ends and is supported on the eccentric wheel 3. The roller body 12 can freely rotate on the mounting shaft 11 to meet the requirements of the rubber tube 100 vulcanization.

[0030] In order to ensure the contact effectiveness of the supporting roller 1 and the eccentric wheel 3, as shown in FIGS. 2, 4 and 6, in some embodiments, a limiting mechanism is further included, which comprises a limiting plate 4 and a limiting notch 41 provided on the limiting plate 4, and the mounting shaft 11 passes through the limiting notch 41 and is supported on the eccentric wheel 3. The limiting notch 41 can limit the position of the mounting shaft 11, avoiding the disengagement of the mounting shaft 11 and the eccentric wheel 3. Meanwhile, the diameter of the roller body 12 is larger than that of the mounting shaft 11, forming a step, so that even without other limiting assistance, when the supporting roller 1 moves axially in a large amplitude, the roller body 12 contacts the limiting plate 4, limiting the axial movement stroke. In addition, the limiting notch 41 can be extended to the bottom of the limiting plate 4, so that the movement track of the eccentric wheel 3 can be located in the limiting notch 41 during rotation, which is more space-saving than the case that the movement track of the eccentric wheel 3 is completely located outside the limiting notch 41, reducing the overall width and floor area of the equipment.

[0031] In some embodiments, as shown in FIG. 6, limiting planes 13 are provided on both sides of the mounting shaft 11, the distance between the limiting planes 13 on both sides is smaller than the width of the limiting notch 41, and the diameter of the mounting shaft 11 is larger than the width of the limiting notch 41. The limiting planes 13 can avoid the rotation of the mounting shaft 11 relative to the eccentric wheel 3. Meanwhile, since the diameter of the mounting shaft 11 is larger than the width of the limiting notch 41, i.e., the limiting step is formed at both ends of the limiting plane 13, the mounting shaft 11 can only move in a small amplitude in the axial direction and cannot move in a large amplitude, effectively ensuring the stability of the equipment operation. During installation, the limiting planes 13 are aligned with the limiting notch 41, the supporting roller 1 is placed in the limiting notch 41, and both ends are supported on the eccentric wheel 3, which is convenient for installation.

[0032] In order to further avoid the adhesion of the rubber tube 100 and the roller body 12, in some embodiments, the surface of the roller body 12 has a Teflon coating. A Teflon cloth can also be pasted on the surface of the roller body 12, or the material of the roller body 12 can be Teflon.

[0033] In order to reduce the friction between the eccentric wheel 3 and the supporting roller 1, reduce wear and tear, and improve the service life of the equipment, in some embodiments, a rolling bearing is provided on the surface of the eccentric wheel 3, and both ends of the supporting roller 1 are supported on the rolling bearing (not shown in the figure). The rolling bearing can convert the sliding friction between the eccentric wheel 3 and the supporting roller 1 into rolling friction, effectively reducing the wear and tear.

[0034] In some other embodiments, the eccentric wheel 3 surface or the side of the supporting roller 1 in contact with the eccentric wheel 3 is provided with a ball bearing (not shown in the figure). The ball bearing on the eccentric wheel 3 surface or the side of the supporting roller 1 in contact with the eccentric wheel 3 can also convert sliding friction into rolling friction and reduce wear.

[0035] In one embodiment, as shown in Figure 9, the two adjacent eccentric wheels 3 on the same driving shaft 2 are staggered by 180°. As shown in Figure 8, when the major axis (the longest diameter between the outer circumference of the eccentric wheel 3 and the axis of the driving shaft 2) of one eccentric wheel 3 moves above the driving shaft 2, the supporting roller 1 on the eccentric wheel 3 rises to contact and support the rubber tube 100, while the major axes of the two adjacent eccentric wheels 3 on both sides of the eccentric wheel 3 are below the driving shaft 2, and the corresponding supporting rollers 1 are lowered and not in contact with the rubber tube 100, as shown in Figure 9. When the driving shaft 2 continues to rotate by 180°, the major axis of the eccentric wheel 3 is below the driving shaft 2, and the supporting roller 1 on the eccentric wheel 3 is lowered and separated from the rubber tube 100, while the major axes of the two adjacent eccentric wheels 3 on both sides of the eccentric wheel 3 are rotated above the driving shaft 2 at this time, and the corresponding supporting rollers 1 are raised to contact and support the rubber tube 100, thereby realizing the alternate support of the rubber tube 100 by the supporting rollers 1 at different positions, and avoiding the problem of adhesion caused by the prolonged contact of the supporting roller 1 at a certain position with the rubber tube 100. Of course, other angles such as 90° can also be staggered. In addition, the driving shaft 2 can be controlled to rotate intermittently or continuously according to actual needs.

[0036] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited to this. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present application.
