Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, in particular to a rubber vulcanizing machine. Background Art

[0002] The rubber vulcanizer is the earliest vulcanization equipment used in the production of rubber products. Although other vulcanization equipment has developed greatly over the years, the vulcanization of some rubber products (rubber hoses, rubber shoes, rubber rollers) still cannot be separated from it. Even molded products, rubber tape products and cable products are also vulcanized in vulcanizing tanks. It can be seen that the rubber vulcanizer is still one of the basic equipment for vulcanization.

[0003] When the existing flat plate vulcanizer is used to produce and process rubber, after the product in the mold is formed, the rubber product will stick to the mold during the heating and vulcanization process, making it difficult to demold the vulcanized rubber product. In addition, since the surface temperature of the vulcanized rubber block is high, it is difficult for workers to remove the product later. Therefore, the utility model designs a rubber vulcanizer to solve the problems existing in the prior art. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

By setting the moving component 8, the heating plates 9 on the surfaces of the two symmetrical lifting plates 6 can move relative to or oppositely at the same time, so that after the rubber block is vulcanized by the two heating plates 9, the two heating plates 9 move oppositely at the same time. No matter whether the rubber block is adhered to the upper surface of the heating plate 9 or the lower surface of the heating plate 9, the rubber block can be separated from the adhesion to the heating plate 9 under the action of the pushing component 10 inside the heating plate 9, which provides convenience for taking the rubber block. The heating plates 9 are fixedly installed on the opposite sides of the two lifting plates 6, and the interior of the heating plates 9 is symmetrically provided with through grooves 901, and the interior of the heating plates 9 is provided with a pushing component 10 between the through grooves 901 and the adjacent lifting plates 6. By setting the pushing assembly 10, after the vulcanization of the rubber block is completed, the two lifting plates 6 move in opposite directions at the same time, so that the other end of the T-shaped movable rod 1001 is pressed, thereby pushing the pushing plate 1002 at one end of the T-shaped movable rod 1001 to move out of the corresponding through groove 901, and pushing the rubber block adhered to the surface of the heating plate 9 due to heating away from the adhesion with the heating plate 9, avoiding the problem that the vulcanized rubber block is inconvenient for the user to remove due to the high surface temperature and adhesion to the mold surface, thereby improving the efficiency of the entire vulcanization process.

[0021] See also Figure 1 In this embodiment, the upper and lower ends of the threaded rod 7 are both provided with threads, and the threads of the upper and lower ends are arranged in opposite directions. Since the threads of the upper and lower ends of the threaded rod 7 are arranged in opposite directions, when the threaded rod 7 rotates, the two lifting plates 6 symmetrically threadedly mounted on the surface of the threaded rod 7 move relatively at the same time, thereby clamping the rubber block placed on the top of the heating plate 9 below, and heating it for vulcanization.

[0022] See also Figure 1 In this embodiment, the mounting plate 5 and the support plate 3 are both symmetrically provided with bearings, and the inner ring of the bearing is fixedly connected to the surface of the threaded rod 7, and the outer ring of the bearing is fixedly connected to the inner part of the adjacent mounting plate 5 and the adjacent support plate 3. The bearing arrangement further improves the rotation stability of the threaded rod 7.

[0023] See also Figure 1In this embodiment: the moving component 8 includes: a first bevel gear 801, a servo motor 802, a rotating shaft 803 and a rotating shaft 803, two first bevel gears 801 are provided, the two first bevel gears 801 are respectively fixedly mounted on the bottom of the adjacent threaded rod 7, the servo motor 802 is fixedly mounted on the surface of one side of the adjacent support block 2, the rotating shaft 803 is horizontally rotatably mounted between the two support blocks 2, one end of the rotating shaft 803 extends to one side of the support block 2, and the end of one end of the rotating shaft 803 is fixedly connected to the output end of the servo motor 802, and the surface of the rotating shaft 803 is symmetrically fixedly connected with the second bevel gear 804, and the surface of the second bevel gear 804 is meshed with the surface of the adjacent first bevel gear 801. When vulcanizing the rubber block, the rubber block is placed on the surface of the heating plate 9 below, and the servo motor 802 is started so that the output end of the servo motor 802 drives the rotating shaft 803 to rotate. At this time, the symmetrical second bevel gear 804 on the surface of the rotating shaft 803 is meshed with the first bevel gear 801 at the bottom of the corresponding threaded rod 7. At this time, the two symmetrical threaded rods 7 rotate synchronously, and the lifting plates 6 symmetrically threadedly installed between the two threaded rods 7 move relatively at the same time. Through the movement, the two heating plates 9 on the opposite side of the two lifting plates 6 clamp the upper and lower surfaces of the rubber block, and then the clamped rubber block is heated and vulcanized by the heating plates 9.

[0024] See also Figure 1 In this embodiment, a positioning block is rotatably mounted in the middle of the rotating shaft 803, and the bottom of the positioning block is fixedly mounted on the surface of the base 1. By setting the positioning block, the stability of the installation of the rotating shaft 803 is further improved.

[0025] See also Figure 1-2In this embodiment: the pushing assembly 10 includes: a T-shaped movable rod 1001, which is movably arranged inside the lifting plate 6, one end of the T-shaped movable rod 1001 extends to the inside of the adjacent through groove 901, and a push plate 1002 is fixedly connected to the end of one end of the T-shaped movable rod 1001, and the side wall of the push plate 1002 is in contact with the side wall of the through groove 901, and the surface of the push plate 1002 is flush with the surface of the heating plate 9, when the reset spring 1003 pushes the T-shaped movable rod 1001 to reset, the surface of the push plate 1002 and the surface of the heating plate 9 are on the same plane, and when the rubber block is clamped, its stability is improved, and the surface of the other end of the T-shaped movable rod 1001 is covered with a reset spring 1003, and one end of the reset spring 1003 is fixedly connected to the surface of the lifting plate 6, and the other end of the reset spring 1003 is fixedly connected to the surface of the other end of the T-shaped movable rod 1001. After the two heating plates 9 are heated to complete the vulcanization of the clamped rubber blocks, the threaded rod 7 rotates in the opposite direction to make the two symmetrical lifting plates 6 move in opposite directions at the same time. When the lifting plates 6 move close to the corresponding support plates 3 and mounting plates 5, the other end of the T-shaped movable rod 1001 is squeezed on the surfaces of the corresponding support plates 3 and mounting plates 5. At this time, the T-shaped movable rod 1001 pushes the push plate 1002 at one end to move out of the corresponding through groove 901, thereby pushing the rubber blocks adhered to the surface of the heating plates 9 due to heating away from the adhesion with the heating plates 9, avoiding the problem that the vulcanized rubber blocks are inconvenient for users to remove due to the high surface temperature and adhesion to the mold surface, thereby improving the efficiency of the entire vulcanization process.

[0026] See also Figure 1-2 In this embodiment, a positioning ring is fixedly connected to the surface of one end of the T-shaped movable rod 1001, and the surface of the positioning ring is placed on the surface of the lifting plate 6. When the other end of the T-shaped movable rod 1001 is not pressed by external force, the reset spring 1003 pushes the T-shaped movable rod 1001 to reset. When the positioning ring on the surface of one end of the T-shaped movable rod 1001 fits on the surface of the lifting plate 6, the T-shaped movable rod 1001 completes the reset action, and the push plate 1002 at one end of the T-shaped movable rod 1001 is flush with the surface of the heating plate 9, thereby ensuring that the push plate 1002 always remains flush with the surface of the heating plate 9 after reset.

[0027] Working principle: When the power is turned on, during the vulcanization operation of the rubber block, the rubber block is first placed on the surface of the heating plate 9 below, and the servo motor 802 is started to drive the output end of the servo motor 802 to rotate the shaft 803. At this time, the symmetrical second bevel gear 804 on the surface of the shaft 803 is meshed with the corresponding first bevel gear 801 at the bottom of the threaded rod 7. At this time, the two symmetrical threaded rods 7 rotate synchronously, and the lifting plates 6 symmetrically threadedly installed between the two threaded rods 7 move relatively at the same time. Through the movement, the two heating plates 9 on the opposite side of the two lifting plates 6 clamp the upper and lower surfaces of the rubber block, and then the heating plates 9 clamp the upper and lower surfaces of the rubber block. The rubber block held by the two heating plates 9 is heated and vulcanized. After the two heating plates 9 heat and vulcanize the clamped rubber block, the two symmetrical lifting plates 6 are simultaneously moved in opposite directions by the reverse rotation of the threaded rod 7. When the lifting plates 6 move close to the corresponding support plate 3 and the mounting plate 5, the other end of the T-shaped movable rod 1001 is pressed on the surface of the corresponding support plate 3 and the mounting plate 5. At this time, the T-shaped movable rod 1001 pushes the push plate 1002 at one end to move out of the corresponding through groove 901, thereby pushing the rubber block adhered to the surface of the heating plate 9 due to heating away from the adhesion with the heating plate 9, so that the user can take out the vulcanized rubber block.
