[0021] like Figures 1 to 5 As shown, a carat tube winding mold preheating device, a mounting base 11 is provided on the movable base on one side of the carat tube mold 2, a U-shaped structure fixed base 5 is provided on the mounting base 11, the middle part of the fixed base 5 is hinged to the flame-throwing tube 6, the fixed base 5 is provided with a swing device, the swing device is connected to the flame-throwing tube 6, driving the flame-throwing tube 6 to swing up and down, the flame-throwing tube 6 is connected to the flame-throwing nozzle 12 toward the carat tube mold 2 end, the flame-throwing nozzle 12 is covered with two split protective covers 1 on the outside, and the two protective covers 1 are hinged to the upper end of the fixed base 5.

[0022] This device is designed to improve the heating efficiency and safety during the preheating process of the carat tube mold 2. A mounting base 11 is installed on the movable base on one side of the carat tube mold 2. This mounting base 11 serves as the foundational support for the entire preheating device, ensuring that the flame assembly can move smoothly with the movable base and heat the mold. A U-shaped fixing base 5 is installed on the mounting base 11. This fixing base 5 supports and secures the flame assembly, ensuring its stability and adjustability during the heating process. The fixing base 5 is hinged at the center to the flame tube 6, allowing the flame tube 6 to be adjusted within a certain range to meet the heating requirements of different positions.

[0023] The mounting base 5 is also equipped with a swinging device, which is connected to the flame tube 6 and can drive the flame tube 6 to swing up and down, thereby achieving more uniform heating treatment on the mold surface. The end of the flame tube 6 facing the carat tube mold 2 is connected to the flame nozzle 12. The flame nozzle 12 is the direct output port of the flame. By adjusting the position and angle of the flame nozzle, the coverage and intensity of the flame can be precisely controlled to ensure uniform heating of the mold surface.

[0024] To enhance safety and prevent accidental injuries from flame spread, the flame nozzle 12 is covered with two split protective covers 1, hinged to the upper end of the mounting base 5. This design not only forms an effective protective barrier to prevent flame spillage during operation, but also allows for easy maintenance and inspection of the nozzle when needed. The two protective covers ensure safety during the heating process while maintaining ease of operation.

[0025] In the preferred embodiment, a protruding block is provided at the upper end of the fixing seat 5 , the ends of the two split protective covers 1 are hinged to the protruding block, and the flamethrower 6 passes through the two split protective covers 1 and is connected to the flamethrower 12 .

[0026] A block extends from the upper end of the mounting base 5, providing a hinge point for the two split protective covers 1 to be freely opened and closed. The ends of the two split protective covers 1 are hinged to the block extending from the upper end of the mounting base 5. This design allows the covers to be opened when not in use, facilitating inspection and maintenance of the internal flame nozzles 12. When in use, they can be closed, providing a sealed working environment for the flame nozzles, preventing flame leakage and increasing safety during the heating process.

[0027] The flame tube 6 passes through the two split protective covers 1 and connects to the flame nozzle 12. This means that the flame tube 6 not only transmits the flame, but its end is directly connected to the flame nozzle 12, ensuring that the flame can be accurately ejected from the flame nozzle 12 to heat the carat tube mold 2. The flame tube 6 is designed to swing up and down driven by the swing mechanism of the fixed base 5, thereby achieving uniform heating of the mold surface. Furthermore, the design of the flame tube 6 passing through the protective cover further enhances operational safety and avoids the risks of direct contact with the flame.

[0028] In the preferred embodiment, a cylinder 4 is provided on one or both sides of the fixing base 5. One end of the cylinder 4 is hinged to the head end of the protective cover 1 and the other end is hinged to the fixing base 5. The two cylinders 4 are used to drive the two protective covers 1 to open. Figure 3-5 As shown, cylinders 4 are installed on one or both sides of the fixing base 5. These cylinders 4 function as driving devices to control the opening and closing of the protective cover 1. One end of the cylinder 4 is hinged to the head end of the protective cover 1, allowing the protective cover 1 to rotate with the movement of the cylinder. The other end is connected to the fixing base 5 to ensure that the cylinder 4 has sufficient support force to perform the extension and retraction movement during operation.

[0029] When the protective covers 1 need to be opened, the two cylinders 4 operate synchronously, telescoping to drive the two protective covers 1 outward, exposing the flame nozzles 12 for easy maintenance or replacement. When heating operations are required, the cylinders 4 drive the protective covers 1 closed, creating an enclosed space that protects the operator from direct contact with the high-temperature flames and prevents the spread of flames, thereby improving the safety of the heating process. This design not only simplifies the opening and closing of the protective covers but also improves the convenience and safety of the equipment.

[0030] In the preferred embodiment, the protective cover 1 covers the carat tube mold 2 , and a steel brush 3 is provided at the edge of the inner ring of the protective cover 1 contacting the carat tube mold 2 , and the steel brush 3 leans against the surface of the carat tube mold 2 .

[0031] Protective cover 1 covers the carat tube mold 2, isolating the flame from the external environment, protecting the operator and preventing accidents such as fire. A steel brush 3 is installed on the edge of the inner ring of the protective cover 1 where it contacts the carat tube mold 2. Steel brush 3 rests closely on the surface of the carat tube mold 2 and cleans the mold surface as the heating device moves along the axis of the carat tube mold 2. The provision of steel brush 3 not only removes impurities and residue from the mold surface but also helps improve the cleanliness of the mold surface, thereby improving heating efficiency and carat tube production quality. Throughout the heating process, as the heating structure moves, steel brush 3 continuously cleans the surface of the carat tube mold 2, ensuring a clean and tidy mold surface.

[0032] In the preferred embodiment, the outer surface of the protective cover 1 is provided with multiple exhaust holes 101. These holes 101 allow exhaust gases generated during the heating process to escape, preventing excessive pressure or accumulation within the protective cover 1. The design of the exhaust holes 101 helps maintain pressure balance within the protective cover 1 while also reducing uneven heat distribution caused by exhaust gas accumulation, thereby ensuring a smooth heating process. Through these holes 101, exhaust gases can be smoothly discharged, maintaining a safe heating environment and effective heating results.

[0033] In the preferred embodiment, an avoidance groove 102 is provided at the root of the protective cover 1 , and the flamethrower 6 passes through the avoidance groove 102 of the protective cover 1 and is connected to the flamethrower 12 .

[0034] A clearance groove 102 is provided at the base of the protective cover 1. Its primary function is to provide space for the flamethrower 6 to pass through the protective cover 1 and connect with the flame nozzle 12. The design of the clearance groove 102 ensures that the flamethrower 6 has ample room to maneuver when swinging up and down, without being affected by the structural limitations of the protective cover 1. This not only ensures the flexibility of the flamethrower 6 but also ensures that the flame is evenly sprayed onto the carat tube mold 2 during the heating process.

[0035] In the preferred embodiment, the swing mechanism is structured as follows: a motor 9 is provided on one side of the fixed base 5. The output end of the motor 9 is connected to a crank disk 10. The outer ring of the crank disk 10 is hinged to the flame tube 6 via a rocker 8. One end of the rocker 8 is hinged to the flame tube 6, and the other end is hinged to the outer ring of the crank disk 10. The motor 9 is provided on one side of the fixed base 5 as a power source. Its output end is connected to the crank disk 10, and the rotation of the motor 9 drives the crank disk 10 to rotate. The outer ring of the crank disk 10 is hinged to the flame tube 6 via a rocker 8. One end of the rocker 8 is hinged to the flame tube 6, and the other end is hinged to the outer ring of the crank disk 10. This structural design allows the motor 9 to swing up and down through the linkage between the crank disk 10 and the rocker 8 after it is started, thereby achieving uniform heating of the surface of the carat tube mold 2 by the flame tube 6. By adjusting the speed and direction of the motor 9, the amplitude and frequency of the flame tube 6's swing can be controlled, thereby optimizing the heating effect.

[0036] In the preferred embodiment, the tail end of the flame tube 6 is connected to the gas supply pipe 7. This connection provides the flame tube 6 with the gas fuel required for combustion. Fuel is delivered to the flame tube 6 via the gas supply pipe 7, ensuring that the flame nozzle 12 can continuously emit flames to preheat the carat tube mold 2. The design of the gas supply pipe 7 ensures a stable fuel supply, making the heating process more continuous and controllable.
