A sliding rod 904 is fixedly connected to the outside of the second clamping block 902. The left end of the sliding rod 904 passes through the blocking block 6 and is fixedly connected to a circular column 905. The sliding rod 904 and the blocking block 6 are slidably connected. There are two rods 904 and springs 903. A rotating shaft 906 is rotatably connected to the left side of the blocking block 6. Two rotating shafts 906 are provided. A blocking block 907 is fixedly connected to the left end of the rotating shaft 906. The blocking block 907 and the circular cylindrical block 905 are slidably connected. The PLC controller, resistance wire heater 2, motor 302, and air pump 803 are electrically connected to facilitate the operation of the control components. When the operator needs to replace the nitrogen cylinder 805, the operator first disconnects the gas pipe 804 connected to the nitrogen cylinder 805, and then rotates the blocking block 6. The two blocking blocks 907 on the left side of the stop block 6 allow the operator to grasp the circular column block 905 and pull the slide bar 904 to move the clamping block 902 and compress the spring 903. The operator can then remove the nitrogen cylinder 805 from the square slot 7. The design of the blocking block 6, the square slot 7, and the disassembly structure 9 allows the operator to replace the nitrogen cylinder 805 without the need for tools, saving time and effort. At the same time, the blocking block 6 protects the outside of the nitrogen cylinder 805 from dust accumulation, saving the operator the workload of cleaning the nitrogen cylinder 805.

[0025] The rotating structure 3 includes a round rod 301, which is disposed inside the housing 1. A motor 302 is fixedly connected to the rear side of the housing 1. Two motors 302 and round rods 301 are provided. The rear end of the round rod 301 passes through the housing 1 and is fixedly connected to the output end of the motor 302.

A control block 305 is fixedly connected to the front end of the threaded rod 304. The round rod 301 and the housing 1 are rotatably connected. Rod 304 and round rod 301 are threaded together. The nitrogen structure 8 includes an air inlet 801, which is located on the upper side of the housing 1. An air pipe 802 is installed inside the air inlet 801, and an air pump 803 is fixedly connected to the other end of the air pipe 802. A nitrogen cylinder 805 is installed inside the square slot 7. An air pipe 804 is movably connected between the nitrogen cylinder 805 and the air pump 803. The air pump 803 is fixedly connected to the housing 1, and the air pipe 802 is also fixedly connected to the housing 1. Clamping block 90... Clamp 1 and clamp 2 are arc-shaped. Clamp 1 901 and nitrogen cylinder 805 are movably connected. Clamp 2 902 and nitrogen cylinder 805 are movably connected. When the worker installs the coiled nylon 6, first hold the control block 305 to rotate the threaded rod 304 to remove it. Then the worker rotates the threaded rod 304 into the circular groove 303. The control block 305 is used to prevent the coiled nylon 6 from falling off the circular rod 301. Then another circular rod 301 is fitted with an empty coil, and then the nylon... Nylon 6 is wound around the groove 5 of the cylindrical block 4 once, and then fixed by the empty roll. During the operation of motor 302, the two motors 302 operate at different speeds to facilitate the drawing of nylon 6. During the heating of the resistance wire and the drawing of nylon 6, the air pump 803 is started to send nitrogen from nitrogen cylinder 805 into air inlet 801 through air pipe 1 802 and air pipe 2 804. In this way, the box is slowly filled with nitrogen, and nylon 6 can be drawn several more times during this process, so that the anti-oxidation treatment of nylon 6 is better.

[0026] Working principle: When the operator performs anti-oxidation treatment on nylon 6, the operator first places the rolled nylon 6 on the outside of one of the round rods 301 of the rotating structure 3, and then winds it into the groove 5 of the cylindrical block 4, and then fixes it with another round rod 301. The operator holds the handle 11 to close the box door 10 to prevent gas leakage, starts the resistance wire heater 2, and starts the motor 302 to stretch the nylon 6. At the same time, the nitrogen structure 8 is started to fill the box with nitrogen. During this process, the nylon 6 can be treated to prevent oxidation. Since there is a transparent glass block inside the box door 10, the operator can observe the processing of the nylon 6 inside the box. When the nitrogen in the nitrogen cylinder 805 is used up, the nitrogen cylinder 805 can be replaced using the disassembly structure 9, which is convenient and quick.
