DETAILED DESCRIPTION

[0017] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0019] Example 1 The following is combined with Figure 1 The present invention is further described as follows: a polyurethane spraying polyethylene winding insulation pipe spraying device, such as Figure 1 As shown, it includes a roller conveyor 2, a shell 1 is installed above the roller conveyor 2, both sides of the shell 1 are provided with a through hole, a spraying device is installed in the shell 1, a feeding device is installed and connected to the side of the spraying device, a detection component is installed in the feeding device, and camera components 3 are installed on both sides of the outer side of the shell 1.

[0020] like Figure 1 As shown, the feeding device includes a feeding pipe 5 and a material box 4, the feeding pipe 5 is fixedly connected and communicated with the side of the spraying device, the material box 4 is detachably connected to the end of the feeding pipe 5, and an extraction pump 6 is installed on the feeding pipe 5; the detection component includes a pressure sensor, a temperature sensor and a flow detector 7, the pressure sensor and the temperature sensor are both installed at the bottom of the material box 4, the flow detector 7 is installed on the feeding pipe 5, and laser rangefinders are installed on both sides of the outer periphery of the outer shell 1.

[0021] In the present invention, the pressure sensor can sense the weight of the polyurethane spray material in the material box 4, and the flow detector 7 can detect the flow of the polyurethane spray material in the feed pipe 5.

[0022] In the present invention, the camera assembly 3 is an existing camera system.

[0023] In the present invention, two sides of the outer circumference of the housing 1 are respectively an inlet end and an outlet end.

[0024] In the present invention, the diameter of the unsprayed steel pipe 19 and the diameter of the sprayed steel pipe 19 can be detected respectively by two laser range finders.

[0025] In the present invention, the roller conveyor 2 is externally connected to a control system, and the spraying device, the feeding device, the detection component and the camera component 3 are all connected to the control system for communication.

[0026] In the present invention, the extraction pump 6 of the feeding device, the pressure sensor, the temperature sensor, the laser rangefinder and the flow detector 7 of the detection component are all connected to the control system for communication.

[0027] In the present invention, the amount of polyurethane spray material required for spraying a steel pipe 19 can be obtained through a pressure sensor. When the steel pipe 19 enters the outer shell 1, the pressure sensor is turned on to obtain the weight of the polyurethane spray material in the material box 4. After the steel pipe 19 is sprayed, the weight of the polyurethane spray material in the material box 4 detected by the pressure sensor is obtained.

[0028] In the present invention, the staff can analyze the data transmitted by the pressure sensor and the flow detector 7 obtained by the control system. For example, when the pressure is normal but the flow is abnormal, it may be that the feed pipe is blocked; and when the pressure and flow drop abnormally at the same time, it may be that there is insufficient paint in the material box 4 or the extraction pump 6 fails.

[0029] In the present invention, when the steel pipe 19 to be sprayed enters the housing 1, the camera assembly 3 located at the entrance end outside the housing 1 will shoot and record the steel pipe 19 to be sprayed, and the corresponding laser rangefinder will also detect the diameter of the steel pipe 19 to be sprayed.

In this process, the pressure sensor installed at the bottom of the material box 4 can monitor the pressure of the polyurethane spray material in the material box 4 in real time, so as to timely understand the remaining amount of raw materials in the material box 4, and the temperature sensor can monitor the temperature of the polyurethane spray material in the material box 4 in real time, and the flow detector 7 installed on the feed pipe 5 can accurately detect the polyurethane spray material. The flow rate of the spray material in the feed pipe 5 ensures that the flow rate of the raw materials delivered to the spraying device meets the requirements of the spraying process. After obtaining a stable supply of urethane spray material, the spraying device evenly sprays the raw materials on the surface of the steel pipe 19 to be sprayed which is transported from the roller conveyor 2. After the spraying is completed, the camera component 3 installed on the outside of the shell 1 can take real-time photos and records of the steel pipe 19 after spraying. The laser rangefinder at the outlet end of the outside of the shell 1 detects the diameter of the steel pipe 19 after spraying, so as to subsequently detect and analyze the spraying quality.
