Description

Technical Field

[0001] This utility model relates to the field of fiberglass pipe curing technology, specifically to a continuous winding fiberglass pipe curing device. Background Technology

[0002] A continuous winding fiberglass pipe curing device is a core piece of equipment in fiberglass pipe production, specifically designed to accelerate the curing of pipes after winding. It integrates heating, temperature control, and cooling modules, precisely heating the fiberglass material wound on the mandrel through electric heating wires and hot air circulation to promote rapid resin cross-linking and curing. Simultaneously, it is equipped with an intelligent temperature control system that monitors and adjusts parameters such as temperature and time in real time to ensure a stable curing process. Once the material has cured, the cooling system quickly intervenes to rapidly cool and set the shape, facilitating pipe demolding. Its high degree of automation and precise temperature control enable continuous production, ensuring uniform and stable strength and quality of the fiberglass pipes. It is widely used in pipe manufacturing in water supply and drainage, chemical, and other fields.

[0003] A search revealed that Chinese patent CN206544271U discloses an automatic curing device for the production of continuously wound fiberglass pipes. The patent describes a technical solution that reduces heat loss by using a closed cover, while the heating device is circumferentially distributed to ensure uniform heating, accelerate the curing process, shorten the curing time, and effectively guarantee product quality and enterprise economic benefits.

[0004] Although the solution reduces heat loss through a closed cover and ensures uniform heating through a circumferentially distributed heating device, it still has obvious defects. The device lacks an adaptive fixing structure for FRP pipes of different diameters. In actual production, the pipe position needs to be adjusted frequently by hand, which is cumbersome and inefficient. At the same time, relying solely on static heating makes it difficult to ensure uniform heating of the pipe in all directions, which can easily lead to insufficient or over-curing in some areas, affecting pipe quality, increasing the defect rate, and failing to meet the needs of modern high-efficiency production. In order to solve this technical problem, this utility model proposes a continuous winding FRP pipe curing device. Utility Model Content

At the same time, relying solely on static heating makes it difficult to ensure uniform heating of the pipe in all directions, which can easily lead to insufficient or over-curing in some areas, affecting pipe quality, increasing the defect rate, and failing to meet the needs of modern high-efficiency production. In order to solve this technical problem, this utility model proposes a continuous winding FRP pipe curing device.

[0016] (1) The motor is installed on the outer casing. After starting, it drives the rotating shaft and connecting frame to rotate, providing power for the rotation of the FRP pipe.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] Example 1: A continuous winding fiberglass pipe curing device includes a base plate 1. A base 11 is fixedly connected to the top right side of the base plate 1. A motor 3 is fixedly connected to the outer wall of the base 11. A rotating shaft 4 is fixedly connected to the output end of the motor 3. A connecting frame 5 is fixedly connected to the other end of the rotating shaft 4. An electric push rod 6 is fixedly connected inside the connecting frame 5. A connecting plate 7 is fixedly connected to the output end of the electric push rod 6. A clamping plate 8 is provided between the connecting plate 7 and the connecting frame 5. An installation plate 12 is fixedly connected to the top left side of the base plate 1. An adjusting screw 13 is threadedly connected inside the installation plate 12. A connecting seat 15 is provided at the other end of the adjusting screw 13. A positioning plate 16 is provided outside the connecting seat 15. Rotating rods 9 are provided at the bottom of both ends of the clamping plate 8. Each rotating rod 9 has a limiting mechanism inside its two ends. Position rod 10, and one end of rotating rod 9 is rotatably connected to clamp plate 8 through limiting rod 10. The other ends of rotating rod 9 on both sides are rotatably connected to connecting plate 7 and connecting frame 5 respectively through limiting rod 10. Connecting sleeve 14 is fixedly connected to the outer wall of connecting seat 15. The other end of adjusting screw 13 is rotatably connected to connecting sleeve 14. Slider 19 is fixedly connected to the bottom of connecting seat 15. Slide groove 20 is opened inside the left side of base plate 1, and slider 19 is slidably connected inside slide groove 20. At the same time, connecting seat 15 is slidably connected to the top of base plate 1. Outer shell 2 is fixedly connected to the top of base plate 1. Inner groove 23 is opened on one side of outer shell 2. Baffle 22 is slidably connected inside inner groove 23. At the same time, multiple electric heating blocks 21 are fixedly installed on the upper surface of base plate 1 and the inner top wall of outer shell 2.

[0025] Pull the baffle 22 upwards to remove it from the inner groove 23, making room for the placement of the fiberglass pipe. Place the fiberglass pipe into the outer casing 2, with one end fitted onto the outside of the connecting plate 7 and the clamping plate 8. Activate the electric push rod 6, which pushes the connecting plate 7 to the right, causing the rotating rods 9 at both ends of the clamping plate 8 to rotate, causing the clamping plate 8 to open outwards and tightly press against the inner wall of one end of the fiberglass pipe. This structure enables rapid fixing of fiberglass pipes of different diameters. Then, rotate the adjusting screw 13, utilizing its threaded connection with the mounting plate 12, to adjust the... The screw 13 moves forward, thereby pushing the connecting seat 15 forward until the positioning plate 16 fits against the other end of the fiberglass pipe, which serves as a limiting support. When the connecting seat 15 moves, the slider 19 is limited in the slide groove 20 to ensure stable movement. The electric heating block 21 is energized and heats up. At the same time, the motor 3 is started, which drives the connecting frame 5 on the rotating shaft 4 to rotate, thereby driving the fiberglass pipe to rotate. The positioning plate 16 rotates flexibly through the bearing 18, so that the fiberglass pipe can rotate in all directions within the outer shell 2, achieving uniform curing and significantly improving work efficiency.

[0026] Working principle: When workers need to fix the fiberglass pipe, they first pull up the baffle 22 and remove it from the inner groove 23. Then, the fiberglass pipe is placed inside the outer shell 2, with one end inserted into the connecting plate 7 and the outside of the clamping plate 8. The electric push rod 6 is activated, causing the connecting plate 7 to move to the right. At this time, the rotating rods 9 at both ends of the clamping plate 8 rotate, causing the clamping plate 8 to open outwards and press against the inner wall of one end of the fiberglass pipe. Through their cooperation, fiberglass pipes of different sizes can be quickly fixed. Then, the adjusting screw 13 is rotated, which, through its connection with the mounting plate 12... The threaded connection causes the adjusting screw 13 to move forward and push the connecting seat 15 forward until the positioning plate 16 is tightly attached to the other end of the fiberglass pipe for limiting support. When the connecting seat 15 moves, it is limited in the slide groove 20 by the slider 19. At this time, the electric heating block 21 is heated by the power supply. At this time, the starting motor 3 drives the connecting frame 5 on the rotating shaft 4 to rotate together, and drives the fiberglass pipe to rotate. The positioning plate 16 rotates through the bearing 18, so that the fiberglass pipe rotates in the outer shell 2, so that the curing operation can be carried out in all directions, improving work efficiency.
