[0020] Embodiment 1

[0021] See also Figure 1-Figure 4 , a heating device for producing an insulation pipe shown in the figure comprises an operating table 1, a transport component 5 is arranged inside the operating table 1, a feeding plate 3 is arranged at one end of the transport component 5, a discharge trough 4 is arranged at the other end of the transport component 5, and a heating frame 2 is fixedly installed on the top of the operating table 1;

[0022] The feeding plate 3 is inclined, and baffles 1 31 are provided on both sides of the feeding plate 3, and baffles 2 41 are provided on both sides of the discharge chute 4;

[0023] Limiting plates 7 are arranged in an array on both sides of the transport component 5, and a pipe 6 is placed between two adjacent limiting plates 7;

[0024] The transport assembly 5 includes a motor 51, the output end of the motor 51 is connected to a connecting rod 52, one end of the connecting rod 52 is rotatably connected to a transport plate 53, a support plate 54 is installed on the top array of the transport plate 53, the support plate 54 is arc-shaped and fits the pipe 6, one end of the transport plate 53 is rotatably connected to the operating table 1 through another connecting rod 52, and the connecting rods 52 at both ends of the transport plate 53 are parallel to each other and have equal lengths;

[0025] The heating frame 2 is provided with an inlet 21 and an outlet 22, the inlet 21 is provided on the feeding plate 3, the outlet 22 is provided on the discharge trough 4, and a ventilation pipe 23 is provided on the top of the heating frame 2;

[0026] A filter screen 24 is provided at the top of the ventilation duct 23, a heating box 25 is connected to the bottom of the ventilation duct 23, a heating wire 251 is installed inside the heating box 25, a connecting pipe 26 is connected to one side of the heating box 25, the heating box 25 is connected to the connecting box 27 through the connecting pipe 26, and an air outlet tube 28 is provided at the bottom of the connecting box 27.

[0027] In this solution, the pipes 6 to be heated are placed on the feeding plate 3 in sequence. The feeding plate 3 is inclined so that the pipe 6 at the lowest position can move to one side of the limiting plate 7. The baffles 31 on both sides of the feeding plate 3 can effectively prevent the pipe 6 from tilting when moving along the feeding plate 3.

[0028] When the pipe 6 is being transported, the motor 51 is used to control the connecting rod 52 to rotate, and a parallelogram structure is formed between the operating table 1, the transport plate 53 and the connecting rods 52 at both ends of the transport plate 53, so that the transport plate 53 always maintains a horizontal state parallel to the operating table 1 while the connecting rod 52 rotates. During the rotation of the connecting rod 52, the transport plate 53 is close to the supporting plate 54 on one end of the feeding plate 3 to lift the pipe 6 from the bottom of the pipe 6. During the rotation of the connecting rod 52, the supporting plate 54 transports the pipe 6 to one side of another limiting plate 7. After a pipe 6 is transported at the bottom of the feeding plate 3, under the action of gravity, the new pipe 6 moves to the bottom of the feeding plate 3 and is close to the limiting plate 7, and waits for the subsequent supporting plate 54 to rotate to its bottom to transport it.

[0029] The motor 51 is used to continuously control the rotation of the connecting rod 52, so that the single pipe 6 moves to the side of different limit plates 7 under the continuous rotation of the transport plate 53, and is finally transported to the discharge trough 4 connected to the other end of the transport component 5 for transportation. The baffles 41 on both sides of the discharge trough 4 can prevent the pipe 6 from tilting when being transported out. The multiple support plates 54 on the transport plate 53 can effectively prevent different pipes 6 from colliding during transportation. At the same time, the motor 51 is used to continuously control the transport plate 53 to transport the pipe 6 at a uniform speed, so that different pipes 6 can move from the feeding plate 3 to the discharge trough 4 at the same time, and make them stay in the heating rack 2 for the same time, so that each pipe 6 can achieve an ideal heating effect;

[0030] During the transportation of the pipeline 6, the pipeline 6 passes through the interior of the heating rack 2. By arranging an air inlet fan in the ventilation pipe 23 inside the heating rack 2, the air outside the heating rack 2 is sucked into the interior of the heating box 25 through the ventilation pipe 23. The filter 24 on the ventilation pipe 23 can prevent external impurities from entering the ventilation pipe 23. The heating wire 251 inside the heating box 25 is used to heat the incoming air. The heated hot air passes through the connecting pipe 26 and is discharged from the air outlet 28 under the action of the air outlet fan in the connecting box 27, and acts on the pipeline 6 passing through the air outlet 28, thereby achieving heating and drying of the pipeline 6.
