[0002] Heat shrink tubing has important applications in the nuclear energy field, such as for cable insulation protection, and must possess properties such as flame retardancy and radiation resistance. During its processing, the pulling device is a key piece of equipment used to pull and stretch the formed heat shrink tubing to achieve specified dimensions and performance requirements. However, existing heat shrink tubing pulling devices have many problems. For example, traditional devices have poor adaptability to heat shrink tubing of different diameters and wall thicknesses, making it difficult to meet diverse product demands. Therefore, this paper presents a flame-retardant pulling device for processing nuclear power heat shrink tubing. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a traction device for processing flame-retardant nuclear power heat shrink tubing. The device uses a lifting mechanism to drive the second belt conveyor to rise and fall, and can adjust the distance between the second and first belt conveyors according to the different diameters of the heat shrink tubing to ensure stable clamping. This solves the problem of poor adaptability of traditional devices to heat shrink tubing of different diameters and wall thicknesses, and overcomes the shortcomings of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A traction device for processing flame-retardant nuclear power heat shrink tubing includes a base plate. A water collection tank is fixed to one side of the upper end face of the base plate. A primary cooling mechanism is fixed in the water collection tank. A secondary cooling mechanism is installed above the base plate and on one side of the water collection tank. Two fixed frames are fixed to the upper end of the base plate and on one side of the secondary cooling mechanism. A first belt conveyor is fixed to the inner side of the two fixed frames.

[0008] As a further embodiment of this utility model: a water pump is fixed at the upper end of the base plate, one end of the water pump's pumping end is connected to the bottom of one side of the water collection tank, one end of the water pump's outlet end is connected to the middle of one side of the strip cooling tank, a drain pipe is connected to the middle of the other side of the strip cooling tank, the inlet pipe is connected to the water supply pipe, and one end of the drain pipe is connected to the collection device.

[0009] As a further embodiment of this utility model: the lifting mechanism includes a support beam fixed to the top of two fixed frames, an electric push rod connected to the lower end of the support beam, and a U-shaped plate connected to the lower end of the electric push rod.

[0010] As a further embodiment of this utility model: the second belt conveyor is fixed to the inner wall of the U-shaped plate, and the second belt conveyor is located inside the two fixed frames.

[0012] As a further improvement of this utility model: a control switch is installed at the top of the base plate, and the water pump and the electric push rod are both electrically connected to the control switch.

[0014] 1.

[0023] The primary cooling mechanism includes a vertical rod 3 fixed in the water collection tank 2, a through hole 5 at the top of the vertical rod 3, and a water inlet pipe 4 installed on the vertical rod 3 above the through hole 5.

[0024] The secondary cooling mechanism includes a fixing rod 12 fixed to the upper surface of the base plate 1. A strip-shaped cooling groove 13 is fixed to the upper end of the fixing rod 12. The top of the opposite sides of the strip-shaped cooling groove 13 are provided with mounting openings 18. Grooved support wheels 19 are rotatably installed at both mounting openings 18.

[0025] A water pump 14 is fixed at the upper end of the base plate 1. One end of the water pump 14 is connected to the water pump pipe 16 at the water pump 14 and is connected to the bottom of one side of the water collection tank 2. One end of the water pump 14 is connected to the water outlet pipe 15 at the water outlet and is connected to the middle of one side of the strip cooling tank 13. A drain pipe 17 is connected to the middle of the other side of the strip cooling tank 13. The water inlet pipe 4 is connected to the water supply pipe and one end of the drain pipe 17 is connected to the collection device.

[0026] The lifting mechanism includes a support beam 6 fixed to the top of two fixed frames 10, an electric push rod 7 connected to the lower end of the support beam 6, and a U-shaped plate 11 connected to the lower end of the electric push rod 7.

[0027] The second belt conveyor 8 is fixed to the inner wall of the U-shaped plate 11, and the second belt conveyor 8 is located inside the two fixed frames 10, and the second belt conveyor 8 is located above the first belt conveyor 9.

[0028] A control switch is installed at the top of the base plate 1, and the water pump 14 and the electric push rod 7 are both electrically connected to the control switch.

[0029] Working principle: The base plate 1 is installed between the heat shrink tubing extruder and the winding machine, so that the through hole 5 of the upright 3 is positioned below the heat shrink tubing outlet. The extruded heat shrink tubing is passed through the through hole 5 and placed on the two grooved support wheels 19. The heat shrink tubing is then passed between the first belt conveyor 9 and the second belt conveyor 8 and wound around the winding machine. The valve of the water supply pipe is opened to allow cold water to enter the through hole 5, initially cooling the extruded heat shrink tubing. The cooling water flows into the water collection tank 2 and collects. The water pump 14 is turned on by the control switch to pump the water in the water collection tank 2 to the strip cooling tank 13. The cooling water... After accumulating in the strip cooling trough 13, the heat shrink tubing is finally discharged from the drain pipe 17. Based on the diameter of the heat shrink tubing, the electric push rod 7 is extended to lower the second belt conveyor 8. The heat shrink tubing is clamped by the second belt conveyor 8 and the first belt conveyor 9, and the descent of the electric push rod 7 is stopped. The heat shrink tubing is pulled by starting the first belt conveyor 9 and the second belt conveyor 8. The heat shrink tubing passes over the two grooved support wheels 19. The heat shrink tubing between the two grooved support wheels 19 sinks into the water in the strip cooling trough 13 due to its own weight. The water in the strip cooling trough 13 cools the heat shrink tubing again.

[0030] Example 2 is an optimization based on Example 1, specifically:

[0031] The water pump 14 can be a miniature metering pump of the MAH model in the LEWA M series, which is convenient for controlling the flow rate of water pumping and ensuring the stability of the water level in the strip cooling tank 13.
