Description

Technical Field

[0001] This utility model belongs to the technical field of tire vulcanizing machines, specifically relating to a self-balancing vulcanizing machine. Background Technology

[0002] A tire vulcanizing machine is a specialized piece of equipment used in the vulcanization process of tire manufacturing. It heats the semi-finished tire rubber carcass, steaming and cooking the rubber to achieve certain product properties such as toughness and wear resistance, thus producing the finished tire. In the tire industry, this process is called vulcanization. Tire vulcanizing machines can be classified into hydraulic vulcanizing machines and mechanical vulcanizing machines based on their transmission methods.

[0003] Existing tire molds range from several tons to over ten tons, with the mold shell accounting for 2 / 3 of the total weight. The vulcanizing machine's power consumption is mainly during the mold opening and closing phase, requiring the transmission system to drive the entire mold to rise and fall, consuming a lot of useless energy. To address this issue, how to design a self-balancing vulcanizing machine has become a problem we need to solve. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a self-balancing vulcanizing machine.

[0005] To achieve the above objectives, this utility model provides a self-balancing vulcanizing machine, including a support frame, a vulcanizing chamber slidably connected inside the support frame, a sliding cable fixedly connected to the top of the vulcanizing chamber, a counterweight fixedly connected to the end of the sliding cable away from the vulcanizing chamber, a pulley rotatably connected inside the support frame, and the sliding cable tensioned on the outer wall of the pulley; and a support assembly, which is used to assist in supporting and fixing the vulcanizing chamber and the counterweight, and is connected to the support frame, the vulcanizing chamber, the sliding cable, and the counterweight.

[0006] In the above technical solution, the support component further includes a rotating part disposed inside the bracket. The outer wall of the rotating part is provided with a spiral groove. The sliding cable is wound inside the spiral groove. A threaded rod is threadedly connected inside the spiral groove. The threaded rod is fixedly connected inside the bracket. The pitch of the spiral groove and the threaded rod are equal.

[0007] In the above technical solution, a slot is further provided at the end of the spiral groove away from the threaded rod, a motor is fixedly installed on the outer wall of the bracket, the output shaft of the motor is inserted into the inside of the slot, and a V-belt is tensioned on the outer wall of the output shaft of the motor.

[0008] In the above technical solution, the V-belt is further tensioned with a bidirectional screw, which is rotatably connected to the inside of the bracket. The outer wall of the bidirectional screw is connected to a first support member and a second support member by a thread. The first support member and the second support member are slidably connected to the inner wall of the bracket. The first support member and the second support member are symmetrically arranged. A first support plate is inserted into the inside of the first support member and the second support member. The first support plate is fixedly connected to the outer wall of the vulcanization chamber.

[0009] In the above technical solution, the top of the second support member is fixedly connected to a first connector, the outer wall of the first connector is fixedly connected to a third support member, the bottom of the first support member is fixedly connected to a second connector, and the outer wall of the second connector is fixedly connected to a fourth support member. The third support member and the fourth support member are arranged symmetrically.

[0010] In the above technical solution, the third support member and the fourth support member are slidably connected to one side of the bracket, and a second support plate is inserted inside the third support member and the fourth support member, and the second support plate is fixedly connected to the bottom of the counterweight block.

[0011] Compared with the prior art, this utility model has the following beneficial effects: By setting up a sliding cable, a counterweight, and a pulley, the gravitational balance between the vulcanizing chamber and the counterweight is achieved through the sliding cable, pulley, and rotating parts. At this time, the driving load on the motor is zero, and the work done is zero, thereby reducing the motor's work load, reducing power consumption, and achieving energy saving and emission reduction. By setting up a support component, the vulcanizing chamber or counterweight can be supported and fixed after it rises to the top. This ensures that the sliding cable only bears weight when it moves the vulcanizing chamber and counterweight up and down, improving the service life of the sliding cable and avoiding safety accidents caused by the vulcanizing chamber or counterweight falling due to accidental breakage of the sliding cable. At the same time, when the counterweight is supported and fixed, it cannot descend to apply pressure to the sliding cable. At this time, the motor stops working, and there is no need to worry about the counterweight pulling the vulcanizing chamber back up through the sliding cable. The motor only works when it moves the vulcanizing chamber and counterweight up and down, which can further reduce power consumption and emissions. Attached Figure Description

[0014] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1 to 5 The self-balancing vulcanizing machine shown includes a support 1, a vulcanizing chamber 2 (upper mold) slidably connected inside the support 1, a sliding cable 3 fixedly connected to the top of the vulcanizing chamber 2, a counterweight 4 fixedly connected to the end of the sliding cable 3 away from the vulcanizing chamber 2, a pulley 5 rotatably connected inside the support 1, and the sliding cable 3 tensioned on the outer wall of the pulley 5; and a support assembly, which is used to assist in supporting and fixing the vulcanizing chamber 2 and the counterweight 4, and is connected to the support 1, the vulcanizing chamber 2, the sliding cable 3 and the counterweight 4.

[0016] like Figures 1 to 6As shown, the support assembly includes a rotating component 6 disposed inside the bracket 1. The outer wall of the rotating component 6 has a spiral groove 7. A sliding cable 3 is wound inside the spiral groove 7. The spiral groove 7 ensures that the sliding cable 3 is wound in an orderly manner, preventing it from piling up and ensuring sufficient turns on the rotating component 6. Insufficient friction during rotation would cause the rotating component 6 to spin idly, affecting the lifting and lowering of the vulcanizing chamber 2 and the counterweight 4. A threaded rod 8 is threadedly connected inside the spiral groove 7, and the threaded rod 8 is fixedly connected inside the bracket 1. The pitch of the spiral groove 7 is equal to that of the threaded rod 8. A slot 9 is provided at the end of the spiral groove 7 away from the threaded rod 8. A motor 10 is fixedly installed on the outer wall of the bracket 1. The output shaft of the motor 10 is inserted into the slot 9. The motor 10 output shaft needs to rotate a certain distance after being inserted into the slot 9 before it drives the rotating part 6 to rotate. When the motor 10 is working, the output shaft first drives the bidirectional screw 12 to rotate through the V-belt 11, and then drives the rotating part 6 to rotate through the slot 9. The rotation of the bidirectional screw 12 drives the connected first support 13 and second support 14 to stop the vulcanizing chamber 2 or the counterweight. 4. Support and fixation to prevent jamming. A V-belt 11 is tensioned on the outer wall of the output shaft of motor 10. A double-headed screw 12 is tensioned inside the V-belt 11. The diameter of the output shaft of motor 10 is the same as the diameter of the double-headed screw 12. The double-headed screw 12 is rotatably connected inside the bracket 1. The outer wall of the double-headed screw 12 is threadedly connected to a first support member 13 and a second support member 14. The first support member 13 and the second support member 14 are slidably connected to the inner wall of the bracket 1. The first support member 13 and the second support member 14 are symmetrically arranged. A first support plate 15 is inserted into the inside of the first support member 13 and the second support member 14. The first connector 16 is fixedly connected to the top of the second support member 14, the third support member 17 is fixedly connected to the outer wall of the first connector 16, the second connector 18 is fixedly connected to the bottom of the first support member 13, and the fourth support member 19 is fixedly connected to the outer wall of the second connector 18. The third support member 17 and the fourth support member 19 are symmetrically arranged and are slidably connected to one side of the bracket 1. The second support plate 20 is inserted into the interior of the third support member 17 and the fourth support member 19 and is fixedly connected to the bottom of the counterweight block 4.

[0017] Working principle: The gravitational balance between the vulcanizing chamber 2 and the counterweight 4 is achieved through the sliding cable 3, pulley 5 and rotating component 6. At this time, the driving load on the motor 10 is zero and the work done is zero, thereby reducing the power load on the motor, reducing power consumption and achieving energy saving and emission reduction.

[0018] Specifically, when the staff needs to start the vulcanizing machine to vulcanize the tires, the motor 10 can be started, so that the output shaft of the motor 10 drives the rotating part 6 to rotate through the slot 9. Then, the rotating part 6 moves the sliding cable 3 through the spiral groove 7. The end of the sliding cable 3 connected to the vulcanizing chamber 2 is released, and the end of the sliding cable 3 connected to the counterweight 4 is retracted, so that the vulcanizing chamber 2 descends along the inside of the bracket 1 to close the mold, and the counterweight 4 rises. Since the vulcanizing chamber 2 and the counterweight 4 have the same weight, the force exerted by the vulcanizing chamber 2 on the rotating part 6 through the sliding cable 3 is the same as the force exerted by the counterweight 4 on the rotating part 6 through the sliding cable 3. Moreover, the two forces pull the rotating part 6 to rotate in opposite directions, so that the two forces can cancel each other out, thereby reducing the power consumption and load required for the rotating part 6 to rotate, achieving the effect of reducing power consumption, saving energy and reducing emissions.

[0019] It should be noted that when the rotating part 6 rotates to retract the sliding cable 3 and winds it inside the spiral groove 7, the relative position of the sliding cable 3 on the rotating part 6 will change, causing the sliding cable 3 to gradually move away from the motor 10. At the same time, the rotating part 6 will rotate along the outer wall of the threaded rod 8, causing the rotating part 6 to move relative to the threaded rod 8, and thus gradually move the rotating part 6 closer to the motor 10. Since the spiral groove 7 and the threaded rod 8 have the same pitch, and the sliding cable 3 and the rotating part 6 move in opposite directions, the relative position of the sliding cable 3 will remain in place and will not change, thus avoiding affecting the lifting and lowering of the vulcanizing chamber 2 and the counterweight 4.

[0020] Simultaneously, when the motor 10 rotates, it drives the bidirectional screw 12 to rotate via the V-belt 11, causing the first support member 13 and the second support member 14 to move closer or further apart along the outer wall of the bidirectional screw 12. When the motor 10 operates and causes the vulcanizing chamber 2 to descend while the counterweight 4 rises, the first support member 13 and the second support member 14 will move further apart, gradually distancing themselves from each other as the vulcanizing chamber 2 descends. This stops clamping and fixing the first support plate 15, thereby stopping the support and fixing of the vulcanizing chamber 2, allowing the first support plate 15 to descend along the interior of the first support member 13 and the second support member 14. As the first support member 13 and the second support member 14 move further apart, the third support member 17 and the fourth support member 19, connected by the first connecting member 16 and the second connecting member 18, will move closer together. The third support member 17 and the fourth support member 19 move closer to each other as the counterweight 4 drives the second support plate 20 to rise, until the vulcanizing chamber 2 descends and closes the mold. At this time, the counterweight 4 rises to the top, and the third support member 17 and the fourth support member 19 clamp and fix the second support plate 20. The weight of the counterweight 4 is supported by the second support plate 20, which prevents the sliding cable 3 from supporting the counterweight 4 or the vulcanizing chamber 2 for a long time. The sliding cable 3 only bears the gravity when it moves the vulcanizing chamber 2 and the counterweight 4, which improves the service life of the sliding cable 3 and avoids the safety accident caused by the vulcanizing chamber 2 or the counterweight 4 falling due to the breakage of the sliding cable 3. It should be noted that when the vulcanizing chamber 2 rises to open the mold and moves to the top, the first support member 13 and the second support member 14 will clamp and fix the first support plate 15, thereby supporting and fixing the vulcanizing chamber 2 through the first support plate 15.

[0021] Furthermore, when the counterweight 4 is supported and fixed by the third support member 17 and the fourth support member 19 through the second support plate 20, the counterweight 4 cannot descend to apply pressure to the sliding cable 3. At this time, the motor 10 stops working, and there is no need to worry about the counterweight 4 pulling the vulcanizing chamber 2 back up through the sliding cable 3. The motor 10 will only work when it drives the vulcanizing chamber 2 and the counterweight 4 to rise and fall, which can further reduce power consumption and emissions.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
