Description

Technical Field

[0001] This utility model belongs to the field of composite pipe processing technology, specifically referring to a pipe outer ring coating device for composite pipes. Background Technology

[0002] Composite pipes are widely used in construction, municipal engineering, and other fields due to their excellent mechanical properties and corrosion resistance. In the production of composite pipes, the adhesive coating process on the outer circumference is a crucial step in ensuring the quality and performance of the pipes. However, existing technologies have some shortcomings in this area.

[0003] In the existing technology, the pipe outer ring coating device has poor adaptability to pipes of different specifications, which increases the trouble of equipment replacement and disassembly when changing production specifications.

[0004] Furthermore, the adhesive layer has weak adhesion to the pipe and is prone to peeling off. "Delamination" after adhesive application is a major hidden danger for later use. The root cause lies in the lack of surface pretreatment. Most small and medium-sized equipment does not have an integrated pretreatment module and relies on manual wiping to remove oil. At the same time, the temperature difference between the melting temperature of the adhesive and the surface temperature of the pipe is too large. After the adhesive comes into contact with the pipe, it cools and shrinks rapidly, resulting in a decrease in interfacial bonding strength. Utility Model Content

[0005] The technical problem this invention aims to solve is that the adhesive coating device for the outer ring of composite pipes is not well adapted to pipe materials and lacks pretreatment functions before adhesive coating.

[0006] The technical solution adopted by this utility model is as follows:

[0007] This utility model proposes a pipe outer ring adhesive coating device for composite pipes, including a processing table. Two sets of fixed seats are fixedly connected to the upper part of the processing table, and electric push rods pass through the two sets of fixed seats. A U-shaped frame is fixedly connected to the output end of the electric push rod. It also includes a combined adhesive coating unit, which includes a glue spraying machine housing fixedly connected to the inner side of the U-shaped frame. The glue spraying machine housing is semi-circular, and the two sets of glue spraying machine housings can be combined to form a ring structure around the outside of the pipe. Several glue spraying heads are provided on the inner side of the glue spraying machine housing, which is distributed circumferentially. A glue storage tank is fixedly connected to the inner wall of the U-shaped frame, and a pump is connected between the glue storage tank and the glue spraying machine housing.

[0008] Furthermore, the processing table is provided with a sliding groove between two sets of fixed seats, and an adjusting bracket is slidably provided on the sliding groove. Positioning plates are fixedly connected to the upper parts of both sides of the adjusting bracket, and threaded rods are screwed onto the positioning plates. The top end of the threaded rods is rotatably connected to limiting posts inserted into both ends of the pipe.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0022] Example 1:

[0023] like Figure 1 , 3 As shown in Figure 4, the present invention proposes a pipe outer ring coating device for composite pipes, including a processing table 1. Two sets of fixed seats 11 are fixedly connected to the upper part of the processing table 1. Electric push rods 12 pass through the two sets of fixed seats 11. A U-shaped frame 13 is fixedly connected to the output end of the electric push rod 12. The device also includes a combined coating unit. The combined coating unit includes a glue spraying machine housing 14 fixedly connected to the inner side of the U-shaped frame 13. The glue spraying machine housing 14 is semi-circular. The two sets of glue spraying machine housings 14 can be combined to form a ring structure around the outside of the pipe. Several glue spraying heads 15 are provided on the inner side of the glue spraying machine housing 14 distributed circumferentially. A glue storage tank 16 is fixedly connected to the inner wall of the U-shaped frame 13. A pump 17 is connected between the glue storage tank 16 and the glue spraying machine housing 14.

[0024] It should be noted that by extending the output end of the electric push rod 12, the U-shaped frame 13 is moved, causing the two sets of glue spraying machine housings 14 to combine and form a ring-shaped structure that wraps around the outside of the pipe. The pump 17 works to extract the glue from the glue storage tank 16 and inject it into the glue spraying machine housing 14, and spray it from the glue spraying head 15 at all angles onto the outer ring of the pipe for glue coating.

[0025] The processing table 1 has a sliding groove 2 located between two sets of fixed seats 11. An adjusting bracket 21 is slidably mounted on the sliding groove 2. Positioning plates 22 are fixedly connected to the upper parts of both sides of the adjusting bracket 21. Threaded rods 23 are screwed onto the positioning plates 22. The top of the threaded rods 23 is rotatably connected to limiting posts 24 inserted into both ends of the pipe. By rotating the threaded rods 23, the limiting posts 24 are adjusted to position the pipe, and the adjusting bracket 21 slides on the sliding groove 2 to adjust the position of the pipe, thus completing the coating of the entire pipe.

[0026] Example 2:

[0027] like Figure 1 ,2 As shown, a connecting platform 3 is fixedly connected to one side of the processing table 1, and a pretreatment cleaning tank 31 is fixedly connected to the upper part of the connecting platform 3. An ultrasonic generator 32 is fixedly connected to the outer wall of the pretreatment cleaning tank 31, and an ultrasonic transducer 33 is laid on the bottom wall of the pretreatment cleaning tank 31.

[0028] Cleaning fluid is injected into the pretreatment cleaning tank 31. After the pipe is placed in, the ultrasonic generator 32 is activated and the ultrasonic transducer 33 generates cavitation bubbles through high-frequency vibration. The cavitation effect causes the bubbles in the liquid to break, forming a local high-pressure impact, thereby achieving precision cleaning of the workpiece surface.

[0029] The processing table 1 is equipped with a support frame 4 located above the sliding groove 2. A fan housing 41 is fixedly connected to the support frame 4. Electric heating modules 42 are provided on both sides of the fan housing 41. A fan 43 passes through the fan housing 41.

[0030] After cleaning, the pipe is removed and positioned using the limiting post 24. It is then dried and preheated below the air outlet housing 41. The electric heating module 42 provides electric heating, and after the fan 43 is activated, hot air is blown out from the air outlet below the air outlet housing 41 to heat the pipe, thus preventing poor adhesion due to a large temperature difference between the adhesive and the pipe during the adhesive application process.

[0031] One end of the sliding groove 2 is fixedly connected to the equipment base 5, and the equipment base 5 is through which the cylinder 51 passes. The output end of the cylinder 51 is fixedly connected to the adjusting bracket 21. By controlling the cylinder 51, the output end extends and retracts to adjust the sliding of the adjusting bracket 21 on the sliding groove 2.

[0032] The above is the entire process of using a composite pipe outer ring adhesive coating device.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
