Description

Technical Field

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

[0002] Currently, when vulcanizing a rubber flat hose, steam enters from one end of the hose and exits from the other end. Through the flow of steam in the pipeline, under a certain steam pressure, the rubber flat hose reaches a certain temperature, and after a period of time, the raw rubber inside the flat hose is vulcanized into mature rubber. During the entire vulcanization process, since a large amount of condensed water is generated by the steam and accumulates under the rubber flat hose, the hose is tightly attached to the support under the action of gravity. Before the rubber is vulcanized, it is relatively sticky, so after a period of time after the vulcanization starts, the surface of the rubber hose will adhere to the support at the same contact point, affecting the product quality. Currently, in the pre-vulcanization stage, the rubber flat hose is manually moved to another contact position at regular intervals to ensure that the contact surface of the hose is not in the same position, so as to reduce the adhesion between the hose and the support. Since the surface temperature of the rubber flat hose is high during vulcanization, the space environment temperature is harsh, and the labor intensity of personnel operation is high, the product quality cannot be effectively guaranteed. Especially for the vulcanization process of large pipelines, with large mass and long length, the product quality cannot be effectively guaranteed. Summary of the Invention

[0003] To solve the defect that the rubber flat hose adheres to the support during vulcanization in the prior art, the present invention provides a rubber tube vulcanization support device.

[0008] In one embodiment, a limiting mechanism is further included. The limiting mechanism includes a limiting plate and a limiting notch arranged on the limiting plate. The mounting shaft passes through the limiting notch and is supported on the eccentric wheel.

[0026] The present invention will be further described below in conjunction with specific implementation manners. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative changes fall within the protection scope of the present invention

[0027] The technical solution adopted by the present invention is as follows Figure 1 and 3 shown, a vulcanization support device for a rubber tube 100 includes a support roller 1, and a plurality of the support rollers 1 are arranged along the length direction of the rubber tube 100 for supporting the rubber tube 100; a lifting mechanism for driving the plurality of support rollers 1 to lift alternately. During the vulcanization process of the rubber tube 100, the lifting mechanism can control the plurality of support rollers 1 to lift alternately, so that the support rollers 1 at different positions alternately support the rubber tube 100, avoiding the adhesion problem caused by long-term contact with the support roller 1 at the same position. The structure is simple and effective Figures 1 to 4 It can be seen from that the support roller 1 is in different positions at the same position

[0028] As Figures 1 to 8 shown, in some embodiments, the lifting mechanism includes a driving unit, and the driving unit is arranged at both ends of the support roller 1. The driving unit includes a drive shaft 2 and an eccentric wheel 3 arranged on the drive shaft 2, and both ends of the support roller 1 are supported on the eccentric wheel 3. That is to say, it includes two driving units. The drive shafts 2 of the two driving units are respectively arranged on both sides of the support roller 1. The two drive shafts 2 rotate synchronously to drive the support roller 1 to rise or fall. One of the drive shafts 2 can be directly connected to the drive mechanism 5 and is connected to the other drive shaft 2 through a sprocket 51 and a chain drive to achieve synchronous rotation, as Figure 5 shown

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

[0030] In order to ensure the effective contact between the supporting roller 1 and the eccentric wheel 3, as Figure 2 , 4 shown in FIGS. 5 and 6, in some embodiments, a limiting mechanism is further included. The limiting mechanism includes a limiting plate 4 and a limiting notch 41 provided on the limiting plate 4. Both ends of the mounting shaft 11 pass through the limiting notch 41 and are supported on the eccentric wheel 3. The limiting notch 41 can limit the position of the mounting shaft 11 and prevent the mounting shaft 11 from separating from the eccentric wheel 3. At the same time, the diameter of the roller body 12 is larger than that of the mounting shaft 11, forming a step. Even without other limiting aids, when the supporting roller 1 undergoes a large axial displacement, the contact between the roller body 12 and the limiting plate 4 limits the axial displacement stroke. Additionally, the limiting notch 41 can be extended to the bottom of the limiting plate 4, so that the movement trajectory of the eccentric wheel 3 can be located within the limiting notch 41 during rotation. Compared with the movement trajectory of the eccentric wheel 3 being completely outside the limiting notch 41, it saves more installation space and reduces the overall width and floor area of the equipment.

[0031] In some embodiments, as Figure 6 shown in FIG. 10, limiting planes 13 are provided on both sides of the mounting shaft 11, and 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 prevent the mounting shaft 11 from rotating relative to the eccentric wheel 3. At the same time, since the diameter of the mounting shaft 11 is larger than the width of the limiting notch 41, that is, limiting steps are formed at both ends of the limiting planes 13, the mounting shaft 11 can only have a small axial displacement and will not have a large displacement, effectively ensuring the operation stability of the equipment. During installation, only need to align the position of the limiting planes 13 with the limiting notch 41, place the supporting roller 1 into the limiting notch 41, and support both ends on the eccentric wheel 3, which is convenient for installation.

[0032] In order to further prevent the rubber tube 100 from adhering to the roller body 12, in some embodiments, the surface of the roller body 12 has a Teflon coating. Teflon cloth can also be pasted on the surface of the roller body 12, or the material of the roller body 12 can be selected as Teflon material.

[0033] In order to reduce the friction between the eccentric wheel 3 and the supporting roller 1, reduce wear, and improve the service life of the equipment, in some embodiments, a rolling bearing is sleeved 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 sliding friction between the eccentric wheel 3 and the supporting roller 1 can be converted into rolling friction by using the rolling bearing, which can effectively reduce wear.

[0034] In some other embodiments, balls (not shown in the figure) are provided on the surface of the eccentric wheel 3 or on the surface of the support roller 1 that contacts the eccentric wheel 3. Providing balls on the surface of the eccentric wheel 3 or on the contact surface between the support roller 1 and the eccentric wheel 3 can also convert sliding friction into rolling friction, and can also play a role in reducing wear.

[0035] In one embodiment, as Figure 9 shown, two adjacent eccentric wheels 3 on the same drive shaft 2 are staggered by 180°. As Figure 8 shown, when the major axis (the diameter with the longest distance from the outer circumference of the eccentric wheel 3 to the axis of the drive shaft 2 is the major axis) of one eccentric wheel 3 moves above the drive shaft 2, the support roller 1 on this eccentric wheel 3 rises to contact and support the rubber tube 100, while the major axes of the eccentric wheels 3 adjacent to both sides of this eccentric wheel 3 are located below the drive shaft 2, and the corresponding support rollers 1 descend and do not contact the rubber tube 100, as Figure 9 shown. When the drive shaft 2 continues to rotate by 180°, the major axis of this eccentric wheel 3 is located below the drive shaft 2, and the support roller 1 thereon descends and disengages from the rubber tube 100, while the major axes of the eccentric wheels 3 adjacent to both sides of this eccentric wheel 3 rotate above the drive shaft 2 at this time, and the corresponding support rollers 1 rise to contact and support the rubber tube 100, thereby realizing the alternating support of the rubber tube 100 by the support rollers 1 at different positions, and avoiding the problem of adhesion caused by the support roller 1 contacting the rubber tube 100 at a certain position for too long. Of course, other angles such as 90° can also be set for staggering. In addition, the rotation of the drive shaft 2 can be controlled 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 thereto. 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 all fall within the protection scope of this application.
