Description

Technical Field

[0001] This utility model relates to the field of tire inner tube production technology, specifically a steam heating device for tire raw materials. Background Technology

[0002] The tire raw material steam heating device is a key process in the "vulcanization" stage of tire manufacturing. It is mainly used to heat the rubber raw material (unvulcanized rubber) with high-temperature steam, causing it to undergo a chemical cross-linking reaction and transform it into vulcanized rubber (cured rubber) with stable structure and excellent performance.

[0003] Currently, traditional tire vulcanization processes often require manual operation by workers. Workers frequently come into contact with molds and inner tubes, engaging in repetitive labor for extended periods. This results in high physical exertion and labor intensity, which is detrimental to workers' health and long-term work efficiency. Furthermore, when workers manually handle materials, they inevitably come into contact with high-temperature molds, which can easily lead to burns and other safety accidents due to improper operation or inadequate protective measures. This poses a threat to workers' personal safety and increases the company's safety management costs and risks. In view of this, we propose a steam heating device for tire raw materials. Utility Model Content

[0004] The main objective of this invention is to provide a steam heating device for tire raw materials, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a steam heating device for tire raw materials, including an operating table. A support frame is connected to the outer wall of the operating table, and a hydraulic cylinder is connected to the outer wall of the support frame. An upper mold is connected to the output end of the hydraulic cylinder, and a lower mold is provided directly below the upper mold. A steam pipe is provided inside the lower mold, and an ejection mechanism is provided on the lower mold. The ejection mechanism includes an electric push rod, which is connected to the outer wall of the lower mold, and a support block is connected to the output end of the electric push rod.

[0006] Preferably, the outer wall of the support frame is connected to a support plate, and the support frame has a through groove.

[0007] Preferably, the support plate is provided with a material picking mechanism, which includes a motor and is connected to the outer wall of the support plate.

[0008] Preferably, the motor output end is connected to a transmission wheel, the transmission wheel is driven by a transmission belt, and the transmission belt is driven by a driven wheel.

[0009] Preferably, the driven wheel has a shaft connected to its outer wall, and the shaft passes through the support plate and is rotatably connected to the support plate.

[0010] Preferably, a rod is connected to the outer wall of the shaft, and a U-shaped rod is connected to the end of the rod. A limiting rod is connected to the outer wall of the U-shaped rod, and multiple sets of limiting rods are provided to limit the inner tube of the tire and improve the stability of material handling.

[0011] Preferably, there are four sets of support blocks, which are circumferentially distributed on the inner wall of the lower mold, and the outer wall of the support block is provided with a sealing gasket.

[0012] This utility model provides a steam heating device for tire raw materials. It has the following beneficial effects:

[0013] (1) The tire raw material steam heating device drives the support blocks through electric push rods to smoothly eject the vulcanized car inner tube from the lower mold. The four sets of circumferentially distributed support blocks with sealing gaskets can apply force evenly, avoiding deformation and damage of the inner tube due to uneven force during ejection, thus effectively ensuring product quality. At the same time, the precise control of the electric push rods can achieve rapid ejection, significantly improving production efficiency.

[0014] (2) The tire raw material steam heating device achieves automatic inner tube feeding through the ingenious combination of motor, transmission wheel, transmission belt, driven wheel, shaft, rod, U-shaped rod and limiting rod. After the ejection mechanism pushes the inner tube to a certain height, the motor drives the transmission system to rotate the U-shaped rod to the appropriate position. When the support block drives the inner tube to descend, the U-shaped rod can accurately support the inner tube. Then the support block separates from the inner tube, and the U-shaped rod brings the inner tube back to its original position to complete the feeding process. The whole process is highly automated and does not require direct manual contact with the mold and inner tube, effectively ensuring the safety of the operator. At the same time, the multiple sets of limiting rods set on the outer wall of the U-shaped rod can effectively limit the inner tube, greatly improving the stability of feeding and further improving production efficiency and product quality.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 This utility model proposes a steam heating device for tire raw materials, including an operating table 1, a support frame 2 connected to the outer wall of the operating table 1, a support plate 21 connected to the outer wall of the support frame 2, a through groove 22 opened in the support frame 2, a hydraulic cylinder 3 connected to the outer wall of the support frame 2, an upper mold 4 connected to the output end of the hydraulic cylinder 3, a lower mold 5 located directly below the upper mold 4, a steam pipe 51 located inside the lower mold 5, and an ejection mechanism located on the lower mold 5.

[0027] In an embodiment of this utility model, in order to eject the inner tube of the car from the inside of the lower mold 5, the ejection mechanism specifically includes an electric push rod 61, which is connected to the outer wall of the lower mold 5. The output end of the electric push rod 61 is connected to a support block 62. There are four sets of support blocks 62, which are circumferentially distributed on the inner wall of the lower mold 5. The outer wall of the support block 62 is provided with a sealing gasket.

[0028] Furthermore, the support plate 21 is provided with a material picking mechanism, which includes a motor 71. The motor 71 is connected to the outer wall of the support plate 21. The output end of the motor 71 is connected to a transmission wheel 72. The transmission wheel 72 is connected to a transmission belt 74. The transmission belt 74 is connected to a driven wheel 73. The outer wall of the driven wheel 73 is connected to a shaft 78. The shaft 78 passes through the support plate 21 and is rotatably connected to the support plate 21. The outer wall of the shaft 78 is connected to a rod 75. The end of the rod 75 is connected to a U-shaped rod 76. The outer wall of the U-shaped rod 76 is connected to a limit rod 77. Multiple sets of limit rods 77 are provided to limit the inner tube of the tire and improve the stability of material picking.

[0029] In this invention, during use, the inner tube is first placed in the lower mold 5. Then, the hydraulic cylinder 3 is activated to close the upper mold 4 and the lower mold 5. Next, the steam device is turned on, allowing steam to enter the mold and vulcanize the inner tube. Once vulcanization is complete, the electric push rod 61 is activated. At this time, the support block 62, fixedly connected to the output end of the electric push rod 61, will drive the inner tube upward. Then, the motor 71 is activated. Through the transmission wheel 72, transmission belt 74, and driven wheel 73, the shaft 78 drives the rod 75 and U-shaped rod 76 to rotate 90 degrees. Figure 2 As shown, the electric push rod 61 is then activated, causing the support block 62 to move the inner tube downwards. When the inner tube descends a certain distance, it will contact the outer wall of the U-shaped rod 76, at which point the U-shaped rod 76 will support the inner tube. Subsequently, the support block 62 will disengage from the inner tube under the drive of the electric push rod 61. Then, the motor 71 is activated again, and the U-shaped rod 76 will return to its original position under the drive of the motor 71, as shown. Figure 3 As shown.
