Description

Technical Field

[0001] This utility model belongs to the field of vulcanizing machine technology, and in particular relates to an electromagnetic heating energy-saving device for a solid tire vulcanizing machine. Background Technology

[0002] A vulcanizing machine is an industrial piece of equipment used for the vulcanization of rubber and plastic products. In the production of solid tires, a vulcanizing machine is needed to vulcanize them in order to improve tire performance and extend their service life. The traditional steam vulcanization process has a large heat loss and can no longer meet the current environmental protection requirements of production. With the development and progress of technology, more energy-efficient electromagnetic heating has gradually replaced steam heating and is being used in the heating and vulcanization process of tires.

[0003] However, during the application of electromagnetic heating devices for vulcanizing machines, the molds are usually exposed to the workshop environment. In order to achieve the vulcanization reaction, the molds need to be heated to maintain a high temperature. In addition, harmful gases such as sulfur dioxide are generated during the heating process, which pollute the working environment. There are technical problems such as not being able to isolate the overheated molds during the vulcanization process and not being able to purify the harmful gases generated by the vulcanization process to ensure the health and safety of the operators.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-4 As shown, this utility model is an electromagnetic heating energy-saving device for a solid tire vulcanizing machine, including a frame 1, an electrical cabinet 9 disposed on one side of the frame 1, and a mold 3 disposed inside the frame 1, and further including:

[0027] The lower heating seat 2 is located below the mold 3 inside the frame 1; the upper heating seat 8 is located above the mold 3 inside the frame 1. A cable drag chain 10 is provided on one side of the front end of the lower heating seat 2 and the upper heating seat 8, supplying power to them. Inner cover plates 19 are located at the top of the lower heating seat 2 and the bottom of the upper heating seat 8 near the mold 3. Electromagnetic heating plates 18 are located inside the lower heating seat 2 and the upper heating seat 8 near the inner cover plates 19. During hot vulcanization, the mold 3 is clamped between the lower heating seat 2 and the upper heating seat 8. The mold 3 is heated by the electromagnetic heating plate 18, so that the tire inside is kept at a high temperature for vulcanization reaction. The lower heating seat 2 and the upper heating seat 8 are equipped with shielding plates 17 at positions close to the electromagnetic heating plate 18 and away from the mold 3. The bottom of the lower heating seat 2 and the top of the upper heating seat 8 are equipped with outer cover plates 16. The inner cover plate 19 and the outer cover plate 16 isolate the electromagnetic heating plate 18 to ensure its safe operation.

[0028] A protective cover 5 is located on the top of the outer side of the frame 1. A lifting and closing mechanism is provided between the other side of the frame 1 and one side of the protective cover 5. The lifting and closing mechanism includes a trough 4, a servo motor 12, a transmission gear 13, a lifting rack 14, a stabilizing slide bar 6, and a positioning slide groove 11. The trough 4 is fixedly connected to the bottom of the other side of the frame 1. A servo motor 12 is provided at the top of the front end of the trough 4. A transmission gear 13 is provided at the output end of the servo motor 12 at the top of the inner side of the trough 4. The lifting rack 14 is located at the middle position on one side of the protective cover 5. The transmission gear 13 meshes with the lifting rack 14. The servo motor 12 drives the transmission gear 13 to rotate clockwise, causing the lifting rack 14 to descend, thereby causing the protective cover 5 to descend and cover the vulcanizing layer. The front and rear ends of the machine are isolated and protected to prevent operators from accidentally getting injured by approaching the overheated mold 3, and to ensure the safe operation of the electromagnetic heating components. After vulcanization, the protective cover 5 can be lifted to pick up and put down the mold 3. The stabilizing slide rod 6 is set at both ends on one side inside the protective cover 5, and the positioning slide groove 11 is set at both ends on the other side of the frame 1. The stabilizing slide rod 6 is symmetrically arranged on one side inside the protective cover 5, and the cross-section of the stabilizing slide rod 6 is "convex". The stabilizing slide rod 6 is inserted into the inside of the positioning slide groove 11, and the stabilizing slide rod 6 can slide up and down in the positioning slide groove 11. When the protective cover 5 is moved up and down, the stabilizing slide rod 6 slides up and down in the positioning slide groove 11 accordingly, so as to stabilize the protective cover 5 and ensure its stable and smooth lifting and lowering movement.

[0029] When in use, the servo motor 12, which is set at the top front end of the tank 4, is started to drive the transmission gear 13 set at its output end to rotate clockwise. This drives the lifting rack 14, which is set at the middle position on one side of the protective cover 5, to descend. This causes the protective cover 5 to descend and cover the front and rear ends of the frame 1. The electromagnetic heating component and the mold 3 are isolated by the protective cover 5. At the same time, the stabilizing slide rod 6, which is fixedly connected to both ends on one side inside the protective cover 5, descends inside the positioning slide groove 11 to stabilize the protective cover 5. After the tire vulcanization treatment is completed, the transmission gear 13 is driven by the servo motor 12 to rotate counterclockwise, which drives the lifting rack 14 to rise, thereby raising the protective cover 5 to pick up and put down the mold 3.

[0030] The purification mechanism is located at the midpoint between both ends of the protective cover 5. The purification mechanism includes a cylinder 7, a negative pressure fan 15, a mesh groove 20, a retaining groove 21, a retaining spring 22, and activated carbon 23. The cylinder 7 is positioned at the midpoint between both ends of the protective cover 5. The negative pressure fan 15 is installed at the outer end of the cylinder 7. The mesh groove 20 is located inside the cylinder 7, and activated carbon 23 is evenly distributed within the mesh groove 20. The negative pressure fan 15 removes the carbon dioxide generated during the vulcanization of the tires inside the vulcanizing machine. Harmful gases such as sulfur are drawn into the interior of the cylinder 7. The activated carbon 23 installed in the mesh groove 20 adsorbs and purifies the harmful gases, preventing them from being directly emitted into the working environment, polluting the air and harming workers' health. The inner sidewalls of the cylinder 7 at both ends of the mesh groove 20 are provided with slots 21. A ring-shaped retaining spring 22 is engaged inside the slots 21. By engaging the retaining spring 22 in the slots 21, the position of the mesh groove 20 inside the cylinder 7 can be limited, and the mesh groove 20 can be easily disassembled to replace the activated carbon 23 to ensure its air purification effect.

[0031] When in use, the negative pressure fan 15 located at the outer end of the cylinder 7 is activated to draw the harmful gas generated during the vulcanization of the tire inside the vulcanizing machine into the cylinder 7 located at both ends of the protective cover 5. At the same time, the activated carbon 23 loaded inside the mesh groove 20 that is limited by the snap ring 22 in the cylinder 7 is used to adsorb and purify the harmful gas.

[0032] Working principle: When using the electromagnetic heating device of the vulcanizing machine, firstly, the mesh groove 20, which is uniformly filled with activated carbon 23, is installed inside the cylinder 7, and the mesh groove 20 is fixed by the snap ring 22 inside the snap ring 21. Then, the mold 3, which contains the tire to be vulcanized, is pushed between the lower heating seat 2 and the upper heating seat 8 inside the frame 1. The mold 3 is then clamped by the lower heating seat 2 and the upper heating seat 8. After the electromagnetic heating plate 18 is turned on, the mold 3 and the tire inside are electromagnetically heated, so that the tire undergoes a vulcanization reaction at a high temperature. At the same time, the servo motor 12 is started to drive the transmission gear 13 to rotate clockwise, which drives the lifting rack 14 to descend, thereby driving the protective cover 5 to descend and cover the front and rear of the frame 1. The electromagnetic heating components and mold 3 are isolated at both ends to prevent external factors from affecting their safe operation and to prevent operators from accidentally touching the overheated mold 3 and getting injured. The negative pressure fan 15 is started to draw the harmful gases generated during the vulcanization of the tire inside the vulcanizing machine into the cylinder 7. The activated carbon 23 in the mesh groove 20 is used to adsorb and purify the harmful gases. After the tire vulcanization is completed, the servo motor 12 drives the transmission gear 13 to rotate counterclockwise, which drives the lifting rack 14 to rise, thereby raising the protective cover 5. At the same time, the stabilizing slide rod 6 moves up and down inside the positioning slide groove 11 to stabilize the protective cover 5. After the lower heating seat 2 and the upper heating seat 8 are separated from the mold 3, the mold 3 can be pulled out for the next heating and vulcanization process.

[0033] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
