[0002] Rubber vulcanizing machines are essential equipment in the production of rubber products. Existing vulcanizing machines are only suitable for producing sheet products and cannot perform segmented moving vulcanization within horizontal or vertical cylindrical or tunnel-shaped containers, nor can they form ring-shaped or linear structures by vulcanizing and splicing rubber products. This limits the products that vulcanizing machines can produce. Therefore, to perform vulcanization processing within cylindrical or tunnel-shaped containers, a new type of rubber vulcanizing molding machine needs to be developed. Summary of the Invention

Detailed Implementation

[0017] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0018] This invention provides a mobile rubber vulcanizing molding machine, comprising a support frame 1, a positioning guide rail 4, and a vulcanizing mold assembly. The end of the support frame 1 can be positioned at the edge of the open end of a hollow rotating container 00. The positioning guide rail 4 is located in the middle of the container 00, with its central axis coinciding with the central axis of the container 00. One end of the positioning guide rail 4 is connected to the middle position of the support frame 1, and the other end is connected to the bottom of the container 00. The vulcanizing mold assembly includes an annular segmented vulcanizing mold 100, a corner vulcanizing mold 200, a head vulcanizing mold 300, and a longitudinal seam vulcanizing mold 400. 0, respectively used to match different positions of container 00; the annular segmented vulcanizing mold 100, corner vulcanizing mold 200, end vulcanizing mold 300, and longitudinal seam vulcanizing mold 400 all have built-in heating devices and are respectively connected to the rotating support 5 through the telescopic mechanism 6, the rotating support 5 being fitted onto the positioning guide rail 4; the corner vulcanizing mold 200 is connected to the support 1 through the thrust mechanism, and the end vulcanizing mold 300 is connected to the support 1 through the push mechanism; the rotating support 5 is connected to the support 1 through the lifting mechanism, used to drive the rotating support 5 to move along the positioning guide rail 4. The heating device can be a high-frequency electromagnetic heater, electric heating rod, etc. The annular segmented vulcanizing mold, corner vulcanizing mold, end vulcanizing mold, and longitudinal seam vulcanizing mold can each cooperate with the telescopic mechanism (the application states of the four sets of molds are as follows). Figure 1 , 3As shown in Figures 5 and 7, driven by the telescopic mechanism, four sets of molds can be placed at the corners, top corners, circumferential seams, vertical seams, and end caps of the container. Driven by the rotating support, the four sets of molds can perform segmented vulcanization of the rubber products in 360 degrees. At the same time, the lifting mechanism drives them to move along the positioning guide rail, thereby splicing the vulcanized rubber to form a ring or linear structure.

[0019] In specific embodiments of the present invention, such as Figure 9 As shown, the rotating support 5 includes a sleeve 16, a slewing bearing 17, and a hydraulic motor 18. The sleeve 16 can be fitted onto the positioning guide rail 4, and the slewing bearing 17 can be fitted onto the outside of the sleeve 16. The slewing bearing 17 is driven to rotate by the hydraulic motor 18 (the internal gear ring of the slewing bearing 17 meshes with the drive gear 19 at the output end of the hydraulic motor 18). The outer wall of the slewing bearing 17 is connected to the telescopic mechanism 6. A connecting rod 20 is provided inside the sleeve 16 along its diameter, and the middle part of the connecting rod 20 is connected to the wire rope 21 of the lifting mechanism 2. Simultaneously, the side wall of the positioning guide rail 4 is provided with an axial guide groove 22 for the connecting rod 20 to pass through. The rotating support with this structure can drive the telescopic mechanism to perform circular motion, and the rotating support can also move along the positioning guide rail under the drive of the lifting mechanism.

[0020] In specific manufacturing, the telescopic mechanism 6 can be a telescopic hydraulic cylinder. The cylinder body of the telescopic hydraulic cylinder is connected to the rotating support 5, and the piston rod of the telescopic hydraulic cylinder can be connected to the annular segmented vulcanizing mold 100, the corner vulcanizing mold 200, the end vulcanizing mold 300, or the longitudinal seam vulcanizing mold 400. Through the telescopic hydraulic cylinder, the four sets of molds can be pressed against the rubber sheets at different parts of the container, applying pressure to the rubber sheets, thereby extruding the heated and melted rubber into sheet shape. When the rubber sheet is partially melted, the hydraulic motor drives the telescopic hydraulic cylinder and the four sets of molds to rotate around the inner wall of the container. One rotation can form an annular structure, and less than one rotation can form an arc-shaped or linear structure; at the same time, under the drive of the feeding mechanism, the overall vulcanization molding is completed along the length of the container.

[0021] In one specific embodiment of the present invention, such as Figure 2 As shown, the annular segmented vulcanizing mold 100 includes an arc-shaped mold plate 7 and a first support frame 8. The arc-shaped mold plate 7 is elongated, and its outer wall can fit against rubber sheets arranged circumferentially along the inner wall of the container 00. The first support frame 8 includes a support plate 81, reinforcing ribs 82, and a connecting plate 83. There are two or more reinforcing ribs 82 arranged in parallel, and two reinforcing ribs 82 are vertically arranged between the support plate 81 and the connecting plate 83. The connecting plate 83 is connected to the telescopic mechanism 6. A heating device is provided between the arc-shaped mold plate 7 and the support plate 81. Figure 1As shown, the annular segmented vulcanizing mold is moved to the bottom of the container by the lifting mechanism; the telescopic hydraulic cylinder pushes the first support frame to fit the arc mold plate 7 with the pre-placed rubber sheet. Under the combined action of the internal heating device, the rubber sheet is vulcanized within a specific time; then the arc mold plate 7 is driven to rotate around the inner wall of the container by the rotating support, and then the lifting mechanism moves the arc mold plate 7 along the positioning guide rail to carry out the next round of vulcanization.

[0022] The rubber sheets at the middle corners or bottom and top corners of the container are made of, for example Figure 3 , 4 The corner vulcanizing mold 200 shown is used for vulcanization. The corner vulcanizing mold 200 includes an L-shaped external corner mold 12 and a second support frame 11. The outer wall of the external corner mold 12 can fit against the rubber sheet at the middle corner or bottom corner of the container 00. The second support frame 11 includes a base 110, ribs 111 and a connecting seat 112. The base 110 is arc-shaped and is located at the inner corner of the external corner mold 12. The connecting seat 112 is located in the middle of the base 110 and is connected to the telescopic mechanism 6 on its side. There are two ribs 111, which are located on both sides of the connecting seat 112 and between the base 110. The thrust rod 10 of the thrust mechanism is located on the top of the connecting seat 112. A heating device is provided between the external corner mold 12 and the base 110. The corner vulcanizing mold 12 can be moved along the positioning guide rail 4 by the lifting mechanism, so that the mold is fixed at the corner and top corner of the container; the telescopic hydraulic cylinder 6 and the pushing hydraulic cylinder 9 of the thrust mechanism are pushed forward, so that the external corner mold 12 is combined with the pre-placed rubber sheet. Under the combined action of the internal heating device, the rubber sheet is vulcanized within a specific time; then circumferential vulcanization and length vulcanization are performed. Among them, the thrust rod can be a telescopic structure, and the length of the thrust rod can be adjusted according to the different positions of the rotating support on the positioning guide rail.

[0023] The rubber sheet at the container head is made of, for example Figure 5 , 6The vulcanizing mold 300 shown is used for vulcanization. The vulcanizing mold 300 includes an L-shaped internal corner mold 14 and a third support frame 13. The internal corner mold 14 can fit into the rubber sheet at the end of the container 00. The third support frame 13 is composed of a first support frame 8 and a second support frame 11. The first support frame 8 is located inside the internal corner mold 14 and is connected to the telescopic mechanism 6. The second support frame 11 is located on top of the internal corner mold 14 and is connected to the pushing mechanism. Heating devices are provided between the internal corner mold 14 and the first and second support frames 8 and 11. The vulcanizing mold 300 can be moved along the positioning guide rail 4 by the lifting mechanism to fix it at the end of the container. At this time, the telescopic hydraulic cylinder 6 and the pushing hydraulic cylinder 9 are activated to apply a pushing force to the first support frame 8 and the second support frame 11 respectively, so that the internal corner mold 14 combines with the pre-placed rubber sheet. Under the combined action of the internal heating devices, the rubber sheet is vulcanized within a specific time.

[0024] In specific design, such as Figure 3 , 5 As shown, the thrust mechanism includes a thrust support rod 10 and a jacking hydraulic cylinder 9. The jacking hydraulic cylinder 9 is mounted on the bracket 1 and can move synchronously along the bracket 1 and the telescopic mechanism 6. The piston rod of the jacking hydraulic cylinder 9 is connected to the thrust support rod 10, and the thrust support rod 10 is connected to the connecting seat 112. The jacking mechanism is the jacking hydraulic cylinder 9, and the piston rod of the jacking hydraulic cylinder 9 is connected to the second support frame 11.

[0025] like Figure 7 , 8 As shown, the longitudinal seam vulcanizing mold 400 includes a rectangular mold plate 15 and a first support frame 8. The outer wall of the rectangular mold plate 15 can fit against the rubber sheet arranged along the horizontal or vertical seam of the inner wall of the container 00. A heating device is provided between the support plate 81 of the first support frame 8 and the rectangular mold plate 15. The longitudinal seam vulcanizing mold 400 can be moved along the positioning guide rail 4 by a lifting mechanism, so that it is fixed at the horizontal or vertical seam of the container. At this time, the telescopic hydraulic cylinder 6 is activated. The piston of the telescopic hydraulic cylinder 6 is fixed together with the first support frame 8. The hydraulic cylinder 6 continues to move forward, so that the rectangular mold plate 15 combines with the pre-placed rubber sheet. Under the combined action of the internal heating device, the rubber sheet is vulcanized within a specific time. Then, circumferential vulcanization and length vulcanization are performed.

[0026] In one specific embodiment of the present invention, such as Figure 1As shown, the support 1 is a ring-shaped main frame and radially arranged support beams on its inner side. The main frame has protruding eaves around its perimeter that can be placed over the top edge of the container 00. There are two or more support beams, with one end converging at the center of the main frame and the other end connected to the main frame. The jacking hydraulic cylinder 9 can slide with the support beams. In practical applications, the number of support beams can be adjusted according to the diameter of the container. If two beams are selected, they can be designed along the diameter of the container.

[0027] In specific design, such as Figure 1 As shown, the lifting mechanism is a hoist 2, which is located in the middle of the support 1 and is connected to the rotating support 5 via a steel wire rope 21. The positioning guide rail 4 is a hollow tube, and the steel wire rope 21 is placed inside the positioning guide rail 4. Alternatively, a gear and rack mechanism can be used to move the rotating support on the positioning guide rail. Furthermore, the positioning guide rail can be made of metal; the container can be made of metal, cement, or other non-metallic materials.

[0028] To further optimize the above solution, a displacement sensor 3 is installed at one end of the positioning guide rail 4, and the displacement sensor 3 can be linked with the hoist 2. In addition, to improve automation, a control cabinet can be installed on the top of the support or the side of the container, and the displacement sensor, hoist, telescopic hydraulic cylinder, jacking hydraulic cylinder, and hydraulic motor can all be connected to the control cabinet. Simultaneously, relevant parameters for the container and vulcanization can be input on the control panel of the control cabinet to facilitate automatic control. Furthermore, the replacement of the vulcanization mold still requires manual intervention.

[0029] In summary, this invention has the advantages of compact structure and high working efficiency. It enables vulcanization processing within cylindrical or tunnel-shaped containers. A support frame is pre-erected at the edge of the hollow container. Depending on the vulcanization location, a segmented annular vulcanizing mold, corner vulcanizing mold, end-cap vulcanizing mold, or longitudinal seam vulcanizing mold is selected. The vulcanizing mold is installed at the movable end of a telescopic mechanism. The telescopic mechanism, thrust mechanism, and / or jacking mechanism press the vulcanizing mold against the rubber sheet on the inner wall of the container. Under the action of an internal heating device, the rubber sheet is vulcanized within a specific time. A rotating support drives the vulcanizing mold to rotate around the inner wall of the container, and a lifting mechanism moves the vulcanizing mold along a positioning guide rail to vulcanize the rubber sheet at different locations on the inner wall of the container in segments. The vulcanized rubber is then spliced ​​to form an annular or linear structure. This invention improves the applicability of the vulcanizing machine.
