All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0030] Combined with Figures 1-4 , an automatic heating device for plastic-steel composite pipes includes a placement rack 1 and a heating box 2 arranged inside the placement rack 1. Both the left and right sides of the placement rack 1 are fixedly connected with fixing racks 11, and there are two groups of fixing racks 11. The inside of the fixing rack 11 is fixedly connected with a first motor 111. Rotating racks 12 are rotatably connected to both groups of fixing racks 11. One side of the rotating rack 12 is fixedly connected with a placement box 121. The top of the placement box 121 is rotatably connected with a knob 122. A flip cover 21 is arranged on the top of the placement rack 1. A handle 211 is fixedly connected to the top of the heating box 2.

[0031] The following further describes the present utility model in conjunction with embodiments.

[0032] Embodiment 1:

[0033] To solve the problem that most of the existing pipe heating devices have relatively simple structures, and during the process of processing pipes, the pipes are often manually turned over by workers, which greatly affects the work efficiency. The following technical solutions are disclosed in this embodiment, specifically as Figures 1-4As shown in the figure, a gear 112 is fixedly connected to the output end of the first motor 111. A toothed ring 113 is fixedly connected to the outer side of the rotating frame 12, and the toothed ring 113 is meshed with the gear 112. One end of the knob 122 extends into the interior of the placement box 121 and is fixedly connected to a positive and negative thread lead screw 123. Both the upper and lower ends of the positive and negative thread lead screw 123 are threadedly connected to sliding blocks 124. The sliding blocks 124 are slidably connected to the interior of the placement box 121. A clamping block 125 is fixedly connected to the sliding block 124. When heating operation needs to be performed on the composite pipe, the pipe can be placed through the openings on the fixing frame 11 and the placement frame 1 at this time. Then, the knob 122 located on the placement box 121 can be rotated. The knob 122 drives the positive and negative thread lead screw 123 to rotate, thereby causing the sliding blocks 124 to slide. The two sliding blocks 124 cause the clamping blocks 125 to rotate, and thus the pipe is clamped by the clamping blocks 125. After fixation, the heating box 2 can be started to heat the pipe. When the heating surface of the pipe needs to be turned over, the first motor 111 can be started at this time. The first motor 111 drives the gear 112 to rotate, thereby causing the toothed ring 113 to rotate. At this time, the toothed ring 113 drives the rotating frame 12 to rotate, thereby causing the placement box 121 to rotate, and further causing the pipe to rotate. At this time, the effect of uniformly heating the pipe can be achieved, realizing the function of automatically turning over the heating surface of the pipe and improving the working efficiency.

[0034] Embodiment 2:

[0035] To solve the problem that the heating structures inside the existing pipe heating devices are generally fixedly connected inside the devices, and it is not easy to replace and maintain them when damage occurs, which affects the use effect. The following technical solutions are disclosed in this embodiment, specifically as Figure 1 、 Figure 4 and Figure 5As shown, a second motor 22 and an electrical connection block 23 are fixedly connected inside the placement rack 1. The output end of the second motor 22 is fixedly connected to a screw rod 221. A sliding plate 222 is threadedly connected to the outside of the screw rod 221, and the sliding plate 222 is slidably connected inside the placement rack 1. A placement groove 223 is formed in the sliding plate 222, and a spring 224 is fixedly connected thereto. The other end of the spring 224 is fixedly connected to a limiting block 225, and the limiting block 225 is matched with the heating box 2. A conductive sheet group 231 is fixedly connected to the bottom of the sliding plate 222, and the conductive sheet group 231 is matched with the electrical connection block 23. The electrical connection block 23 is electrically connected to the heating box 2 through the conductive sheet group 231 and the sliding plate 222. When maintenance of the heating box 2 is required, the flip cover 21 can be opened at this time, and then the second motor 22 is started. The second motor 22 drives the screw rod 221 to rotate, so that the sliding plate 222 slides inside the placement rack 1. At this time, the conductive sheet group 231 is separated from the electrical connection block 23, thereby ensuring that the heating box 2 is in a power-off state. The user can remove the heating box 2 from the sliding plate 222 through the handle 211, and maintenance operations can be performed at this time. When installation is required, the heating box 2 can be placed inside the placement groove 223. At this time, the spring 224 and the limiting block 225 can play an auxiliary clamping effect. Starting the second motor 22 in the reverse direction to reset the sliding plate 222 can complete the installation, achieving the function of being able to replace the heating structure inside the device and improving the use effect.
