[0017] Preferred embodiment.

[0018] This embodiment provides a cable protection pipe production feeding device, including a first frame 100. The left end of the first frame 100 is provided with a first hopper 110, and the right end of the first frame 100 is provided with a first feeder 120. The lower end of the first hopper 110 is provided with a first discharge port, and the upper end of the first feeder 120 is provided with a first inlet. The first inlet and the first discharge port are connected by a first connecting pipe 210. The first frame 100 is provided with a first air pump 130. A first air pipe 220 is provided parallel to one side of the first connecting pipe 210 and is connected to the first air pump 130. A second connecting pipe 240 is provided on the first air pipe 220, and the first connecting pipe 210 and the second connecting pipe 240 are connected. An anti-blocking mechanism is provided inside the second connecting pipe 240.

[0019] Furthermore, the anti-clogging mechanism includes a first piston 250, a first spring 270, and a first baffle 280. The first baffle 280 is disposed at one end of the second connecting pipe 240 near the first connecting pipe 210. The first piston 250 is disposed at one end of the second connecting pipe 240 away from the first connecting pipe 210. A first guide rod 260 is provided at the end of the first piston 250 near the first connecting pipe 210. A first guide hole 281 is provided in the middle of the first baffle 280. The first guide rod 260 matches the first guide hole 281. The first spring 270 is disposed between the first piston 250 and the first baffle 280.

[0020] Furthermore, the anti-clogging mechanism includes a first limiting ring 290, which is disposed at the end of the second connecting pipe 240 away from the first connecting pipe 210, and the first limiting ring 290 matches the first piston 250.

[0021] Furthermore, the anti-clogging mechanism includes a first tamping rod 261, which is disposed at one end of the first guide rod 260 near the first connecting pipe 210, and the end of the first tamping rod 261 near the first connecting pipe 210 is tapered.

[0022] Furthermore, a first solenoid valve 230 is provided at the end of the second connecting pipe 240.

[0023] Working Principle: The first hopper 110 conveys PVC material to the first feeder 120 through the first connecting pipe 210. The first air pump 130 blows air into the second connecting pipe 240. When the first solenoid valve 230 is closed, the air pressure in the second connecting pipe 240 increases, which forces the first piston 250 to move towards the first connecting pipe 210. This allows the first tamping rod 261 to loosen the powder blocking the first connecting pipe 210, preventing severe blockage. When the first solenoid valve 230 is opened, the air pressure in the second connecting pipe 240 returns to normal, and the first spring 270 pushes the first piston 250 back to its original position. The first limiting ring 290 restricts the first piston 250. In other words, the opening and closing of the first air pump 130 and the first solenoid valve 230 drives the first tamping rod 261 to loosen the powder in the first connecting pipe 210, ensuring a stable supply of production powder for the cable protection pipe without blockage. The power source for conveying the powder is a conventional selection.

[0024] It is worth mentioning that the technical features of the first hopper 110 and the first feeder 120 involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be adopted by conventional choices in the field, and should not be regarded as the utility model point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0025] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
