Description

Technical Field

[0001] This invention relates to the field of hollow wall wound tube processing technology, and in particular to a uniform cooling device for hollow wall wound tubes. Background Technology

[0002] Spiral wound pipe is a type of pipe made of high-density polyethylene or nylon through winding and welding. It can be divided into several categories, such as large-diameter spiral wound pipe, double-wall spiral wound pipe, and hollow-wall spiral wound pipe. Due to its excellent wear resistance, aging resistance, and corrosion resistance, it is widely used in the field of wire and cable protection for various engineering machinery and hydraulic equipment. Among them, hollow-wall spiral wound pipe has the most widespread application. The production of hollow-wall spiral wound pipe adopts a heat setting process. The raw material is heated and plasticized by a plastic extruder and extruded into thin strips. After the strips are extruded from the die head, they are wound by a winding machine and cooled and shaped by a cooling device. Then, they can be conveyed and cut.

A pair of heat dissipation fixing holes are drilled on the side of the water storage tank away from the protective cover; a pair of cooling fans are installed in the heat dissipation fixing holes, and a return plate is provided on the side of the cooling fans near the winding equipment body. A return heat dissipation cavity is formed between the return plate and the water storage tank.

[0004] The above-disclosed patents still have the following technical defects: 1. They can only cool the outer wall of the pipe, which has low cooling efficiency. Furthermore, the cooling method of using cold water spraying requires subsequent drying of the pipe surface, otherwise the pipe surface is easily covered with dust; 2. They do not have the function of detecting pipe damage. Summary of the Invention

The nozzle is connected to one end, and the output end of the water pump is connected to the other end of the water supply pipe. A fan is also installed on the cooling water tank, and the input end of the fan is connected to the bottom of the inner wall of the cooling water tank. An annular nozzle is set on the outside of the nozzle, and the output end of the fan is connected to the annular nozzle. A rain detector is set directly below the nozzle, and a controller is set on the mounting platform. A lifting ring is set between two sets of rotary drive mechanisms on one side of the main body of the winding equipment. A gantry frame is set on one side of the mounting platform, and a power component for driving the lifting ring to rise and fall is installed on the gantry frame. A water tank is set below the lifting ring, and the water tank is fixed on multiple support plates.

[0007] Preferably, a circular tube is coaxially arranged on the outer side of the annular nozzle, and the edge of the water tank is provided with support feet for fixing and supporting the circular tube and the annular nozzle.

[0008] Preferably, the water tank is located above the cooling water tank, and a return pipe is provided between the water tank and the cooling water tank, with a filter installed on the return pipe.

[0009] Preferably, the power assembly includes a linear drive mechanism, a lifting plate, and multiple lifting ropes. The lifting plate is slidably mounted on the gantry frame. The linear drive mechanism is mounted on the top of the gantry frame and its output shaft is fixedly connected to the lifting plate.

[0011] Preferably, the multiple drive rollers on the rotary drive mechanism are arranged in a circular array.

[0012] Preferably, a buzzer is installed on the controller, and the controller is electrically connected to the rain detector.

[0013] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects: A water pump draws cooling water from the bottom of the cooling water tank into a nozzle, which then sprays the water onto the inner wall of the pipe, thus cooling the inner wall. A fan draws cold air from the top of the cooling water tank into an annular nozzle, causing the cold air to be evenly blown onto the outer surface of the pipe, thereby cooling the outer wall. A power mechanism drives a drive roller, causing the pipe to rotate during movement, thus achieving uniform cooling of the inner and outer walls of the pipe. During this process, cooling water flows into… If a crack occurs on the surface of the pipe inside the pipe, cooling water will flow out through the pipe wall and can be detected by a rain detector, which will then send a signal back to the controller. After the production of a single pipe is completed, a linear drive mechanism will be used to lift the lifting ring, causing the pipe to tilt. Water in the grooves on the inner wall of the pipe will then flow into a water tank. In summary, this invention can simultaneously achieve uniform cooling of the inner and outer walls of the pipe, resulting in good cooling effect. During the cooling process, pipe damage can be detected, and the external air-cooling method can prevent dust from adhering to the outer wall of the pipe due to moisture. Attached Figure Description

[0017] Example 1

[0018] like Figure 1-3As shown, the present invention proposes a uniform cooling device for hollow wall wound tubes, comprising a mounting platform 2 and a winding equipment body 1 and a cooling water tank 4 respectively disposed at its upper and lower ends; the winding equipment body 1 is equipped with a pressing mechanism 7, a heating mechanism 8, and a rotating roller group 9; multiple sets of rotating drive mechanisms are arranged side by side on one side of the mounting platform 2, each set of rotating drive mechanisms including two support plates 17 and multiple drive rollers 16 rotatably mounted between the two support plates 17, the multiple drive rollers 16 on the rotating drive mechanism are arranged in a circular array, and useful... The power mechanism 18 drives the drive roller 16 to rotate; a cooling device 22 and a water pump 24 are installed on the cooling water tank 4. The input end of the water pump 24 is connected to the bottom of the interior of the cooling water tank 4. A water supply pipe 27 is provided on the main body 1 of the winding equipment, running through both sides. One end of the water supply pipe 27 is connected to a nozzle 14, and the output end of the water pump 24 is connected to the other end of the water supply pipe 27; a fan 23 is also installed on the cooling water tank 4. The input end of the fan 23 is connected to the bottom of the inner wall of the cooling water tank 4. An annular nozzle 13 is provided on the outside of the nozzle 14. The output of the fan 24 is... The outlet is connected to the annular nozzle 13; a circular tube 11 is coaxially arranged on the outer side of the annular nozzle 13, and the edge of the water tank 10 is provided with support legs 15 for fixing and supporting the circular tube 11 and the annular nozzle 13. Placing the circular tube 11 on the outer side of the annular nozzle 13 can prevent the cold air from being blown away and avoid the cold air from dissipating quickly; a rainwater detector 12 is arranged directly below the nozzle 14, and a controller 21 is arranged on the mounting platform 2. A buzzer is installed on the controller 21, and the controller 21 is electrically connected to the rainwater detector 12; two sets of spirals are located on one side of the winding equipment body 1. A lifting ring 19 is provided between the rotating drive mechanisms. A gantry frame 3 is provided on one side of the mounting platform 2. A power component for driving the lifting ring 19 to rise and fall is installed on the gantry frame 3. The power component includes a linear drive mechanism 5, a lifting plate 6 and multiple lifting ropes 20. The lifting plate 6 is slidably mounted on the gantry frame 3. The linear drive mechanism 5 is mounted on the top of the gantry frame 3 and its output shaft is fixedly connected to the lifting plate 6. The lifting plate 6 and the lifting ring 19 are fixedly connected by multiple lifting ropes 20. A water tank 10 is provided below the lifting ring 19 and is fixed on multiple support plates 17.

[0019] The working principle of this invention is as follows: When cooling the pipe (hollow wall wound pipe), the water pump 24 and the fan 23 work simultaneously. The water pump 24 draws cooling water from the bottom of the cooling water tank 4 into the nozzle 14, and finally sprays it onto the inner wall of the pipe through the nozzle 14, thus cooling the inner wall of the pipe. The fan 23 draws cold air from the top of the cooling water tank 4 into the annular nozzle 13, so that the cold air is evenly blown onto the outer surface of the pipe, thereby cooling the outer wall of the pipe. A power mechanism drives the drive roller 16, which in turn drives the pipe to rotate during movement, thus achieving uniform cooling of the inner and outer walls of the pipe. During this process, cooling water flows into the inside of the pipe. If the surface of the pipe is cracked, the cooling water flows out through the pipe wall and can be detected by the rain detector 12, which feeds the signal back to the controller 21. After the production of a single pipe is completed, the lifting ring 19 is driven to rise by the linear drive mechanism 5, thereby tilting the pipe. The water in the grooves of the inner wall of the pipe flows into the water tank 10. In summary, the present invention can simultaneously achieve uniform cooling of the inner and outer walls of the pipe, with good cooling effect. During the cooling process, pipe damage can be detected, and the external air cooling method can prevent the outer wall of the pipe from being covered with dust due to moisture.
