Description

Technical Field

[0002] The invention belongs to the technical field of pipeline manufacturing, and in particular relates to a rubber pipe vulcanization support device. Background Art

[0003] At present, when the rubber flat hose is vulcanized, steam is introduced from one end of the hose and discharged from the other end of the hose. The steam flows in the pipeline, and the rubber flat hose reaches a certain temperature under a certain steam pressure. 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 will be generated by steam and accumulated under the rubber flat hose, causing the bottom of the hose to fit tightly with the support under the action of gravity. The rubber is relatively sticky before it is vulcanized, so after a period of time after the start of vulcanization, the surface of the rubber hose and the support will adhere to each other at the same contact point, affecting the product quality. At present, the rubber flat hose is moved to another contact position by manpower at regular intervals before vulcanization to ensure that the contact surface of the hose surface is not in the same position, so as to reduce the adhesion between the hose and the support. Due to the high surface temperature of the rubber flat hose during vulcanization, the poor temperature of the space environment, and the high intensity of personnel operation, the product quality cannot be effectively guaranteed. Especially for the vulcanization process of large pipelines, the mass is large and the length is long, and the product quality cannot be effectively guaranteed. Summary of the invention

[0017] The present invention will be further described below in conjunction with specific implementation methods. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative changes belong to the protection scope of the present invention.

[0018] The technical solution adopted by the present invention is: Figure 1 and 3 As shown, a vulcanization support device for a rubber tube 100 includes a support roller 1, a plurality of the support rollers 1 are arranged along the length direction of the rubber tube 100, and are used to support the rubber tube 100; and a lifting mechanism is used to drive the plurality of support rollers 1 to alternately lift and lower. During the vulcanization process of the rubber tube 100, the lifting mechanism can control the plurality of support rollers 1 to alternately lift and lower, so that the support rollers 1 at different positions alternately support the rubber tube 100, thereby avoiding the adhesion problem caused by the same position being in contact with the support roller 1 for a long time, and the structure is simple and effective. Figures 1 to 4 It can be seen that the support roller 1 is in different positions at the same position.

[0019] like Figures 1 to 8 As shown, in some embodiments, the lifting mechanism includes a driving unit, and the driving unit is provided at both ends of the support roller 1. The driving unit includes a driving shaft 2 and an eccentric wheel 3 provided on the driving shaft 2, and both ends of the support roller 1 are supported on the eccentric wheel 3. That is to say, two driving units are included, and the driving shafts 2 of the two driving units are respectively provided on both sides of the support roller 1. The two driving shafts 2 rotate synchronously to drive the support roller 1 to rise or fall. One of the driving shafts 2 can be directly connected to the driving mechanism 5, and connected to the other driving shaft 2 through the sprocket 51 and the chain transmission to achieve synchronous rotation, such as Figure 5 shown.

[0020] Specifically, Figures 6-8 As shown, in some embodiments, the support roller 1 includes a mounting shaft 11 and a roller body 12 rotatably disposed on the mounting shaft 11, and the roller body 12 protrudes from both ends of the mounting shaft 11 and is supported on the eccentric wheel 3. The roller body 12 can rotate freely on the mounting shaft 11, meeting the requirements for vulcanization of the rubber tube 100.

[0021] In order to ensure the contact effectiveness between the support roller 1 and the eccentric wheel 3, Figure 2 , 4As shown in Figures 6 and 7, in some embodiments, a limiting mechanism is also included, and the limiting mechanism includes a limiting plate 4 and a limiting notch 41 provided on the limiting plate 4. The two ends of the installation 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 installation shaft 11 to prevent the installation shaft 11 from being separated from the eccentric wheel 3. At the same time, the diameter of the roller body 12 is larger than the installation shaft 11, forming a step. Even without other limiting assistance, when the support roller 1 has a large axial movement, the roller body 12 contacts the limiting plate 4 to limit the stroke of the axial movement. In addition, 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 during the rotation process can be located in the limiting notch 41, which saves more installation space than the movement trajectory of the eccentric wheel 3 completely located outside the limiting notch 41, and reduces the overall width and floor space of the equipment.

[0022] In some embodiments, Figure 6 As shown, the installation shaft 11 is provided with limiting planes 13 on both sides, and the distance between the limiting planes 13 on both sides is less than the width of the limiting slot 41, and the diameter of the installation shaft 11 is greater than the width of the limiting slot 41. The limiting planes 13 can prevent the installation shaft 11 from rotating relative to the eccentric wheel 3. At the same time, since the diameter of the installation shaft 11 is greater than the width of the limiting slot 41, and the diameter of the installation shaft 11 is greater than the width of the limiting slot 41, that is, limiting steps are formed at both ends of the limiting planes 13, so that the installation shaft 11 can only move slightly in the axial direction, and no large-scale transmission occurs, which effectively ensures the stability of the equipment operation. During installation, it is only necessary to align the limiting plane 13 with the limiting slot 41, put the support roller 1 into the limiting slot 41, and support the two ends on the eccentric wheel 3, which is convenient for installation.

[0023] In order to further prevent the rubber tube 100 from sticking to the roller body 12, in some embodiments, the roller body 12 has a Teflon coating on its surface. Teflon cloth may also be pasted on the surface of the roller body 12, or the roller body 12 may be made of Teflon material.

[0024] In order to reduce the friction between the eccentric wheel 3 and the support roller 1, reduce wear and tear, and increase the service life of the equipment, in some embodiments, the surface of the eccentric wheel 3 is provided with a rolling bearing, and both ends of the support roller 1 are supported on the rolling bearings (not shown in the figure). The rolling bearings can convert the sliding friction between the eccentric wheel 3 and the support roller 1 into rolling friction, which can effectively reduce wear and tear.

[0025] In some other embodiments, balls (not shown) are provided on the surface of the eccentric wheel 3 or on the side of the support roller 1 in contact with 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.

[0026] In one embodiment, Fig. 9 As shown, two adjacent eccentric wheels 3 on the same drive shaft 2 are staggered by 180°. Figure 8 As shown, when the long diameter of an eccentric wheel 3 (the longest diameter from the outer periphery of the eccentric wheel 3 to the axis of the driving shaft 2 is the long diameter) moves to above the driving shaft 2, the support roller 1 on the eccentric wheel 3 rises to contact the rubber tube 100 and supports the rubber tube 100, while the long diameters of the adjacent eccentric wheels 3 on both sides of the eccentric wheel 3 are located below the driving shaft 2, and the corresponding support rollers 1 descend and do not contact the rubber tube 100, as shown in FIG. Fig. 9 As shown. When the drive shaft 2 continues to rotate 180°, the long axis of the eccentric wheel 3 is located below the drive shaft 2, and the upper support roller 1 is lowered and separated from the rubber tube 100, while the long axes of the adjacent eccentric wheels 3 on both sides of the eccentric wheel 3 are rotated to above the drive shaft 2, and the corresponding support rollers 1 are raised to contact and support the rubber tube 100, thereby realizing that the support rollers 1 at different positions alternately support the rubber tube 100, avoiding the problem of adhesion caused by the contact time of the support roller 1 at a certain position with the rubber tube 100 being too long. Of course, other staggered angles such as 90° can also be set. In addition, the drive shaft 2 can be controlled to rotate intermittently or continuously according to actual needs.
