After analysis by the applicant, the disadvantage of this technical solution is that the hot air moves from the upper part to the lower part under the action of the heat circulation fan, and then contacts the polyimide fibers upward again for heat treatment, so that the frequency of hot air contacting the polyimide fibers when flowing is low, the heat that the polyimide fibers can obtain is limited, and the heat treatment effect of the polyimide fibers is reduced. In addition, impurities such as dust may exist on the polyimide fibers, which affect the subsequent heat treatment effect, which is not conducive to use. Utility Model Content

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0021] like Figure 1-Figure 3As shown, an intelligent heat treatment device for polyimide fiber filaments for testing provided by the utility model comprises a shell 1, mounting rings 3 are fixedly installed at both ends of the shell 1 through mounting frames 2, an inner cylinder 4 is rotatably installed in multiple sets of mounting rings 3, a plurality of through holes 5 are provided in the middle of the inner cylinder 4, the through holes 5 are evenly distributed along the side wall of the inner cylinder 4, the mounting rings 3 are distributed around the inner cylinder 4, the axis of the inner cylinder 4 is coaxially arranged with the mounting rings 3, multiple sets of symmetrically distributed telescopic parts are fixedly installed at both ends of the inner cylinder 4, the telescopic parts are located in the mounting rings 3, and multiple sets of lifting boxes 7 are fixedly installed on the output ends of the multiple sets of telescopic parts, and the lifting boxes 7 are located in the inner cylinder 4 and are distributed along the length direction of the inner cylinder 4. The surface of the lifting box 7 close to the inner cylinder 4 is connected with an air outlet pipe 8 extending into the inner cylinder 4. The air outlet pipe 8 is provided with multiple groups and is distributed in a linear interval. The air outlet pipe 8 is in sliding contact with the side wall of the inner cylinder 4. The shell 1 is provided with a power component 25 for driving the inner cylinder 4 to rotate. The lifting box 7 is connected with the mounting ring 3. The mounting ring 3 is connected with the first exhaust fan 14 fixedly installed on the shell 1. A cleaning component 26 for cleaning the polyimide fiber filaments is provided at one end of the inner cylinder 4. A heating pipe 22 is fixedly installed at the bottom of the shell 1, and a temperature sensor 24 is fixedly installed at the top of the shell 1.

[0022] Specifically, in order to connect the mounting ring 3 with the lifting box 7, air ducts 9 are opened in the side walls at both ends of the inner tube 4, the air ducts 9 are connected to the mounting ring 3, the end of the air duct 9 away from the mounting ring 3 is connected to a connecting hose 10, and the end of the connecting hose 10 away from the inner tube 4 is connected to the lifting box 7.

[0023] Specifically, in order to connect the first exhaust fan 14 with the mounting ring 3, an exhaust duct 16 and a return duct 15 are connected to the first exhaust fan 14, the exhaust duct 16 is connected to the shell 1, and the end of the return duct 15 away from the first exhaust fan 14 is connected to the mounting rings 3 on both sides.

[0024] Specifically, in order to eliminate static electricity generated during the heat treatment of the polyimide fiber filaments, a static electricity elimination module 23 is fixedly installed on the outer side of the shell 1. The static electricity elimination module 23 is located at the position of the polyimide fiber filament discharge on the shell 1.

[0025] In actual application of this embodiment, the polyimide fiber filaments are pulled by the traction devices placed on both sides of the shell 1, so that the polyimide fiber filaments pass through the cleaning component 26 and the inner tube 4, and the lifting box 7 is driven to move by the telescopic member according to the diameter of the polyimide fiber filaments, so that the air outlet duct 8 moves to a position close to the polyimide fiber filaments, and the heating tube 22 is turned on to heat the air in the shell 1. The air temperature in the shell 1 is detected by the temperature sensor 24, and the detected temperature is fed back to the staff in real time, so that the staff can adjust the heating status of the heating tube 22 according to the temperature change, and the polyimide fiber filaments can be preheated after entering the shell 1. During the heat treatment, the power component 25 drives the inner tube 4 to rotate, and when the inner tube 4 rotates, it drives the air outlet duct 8 to surround the polyimide fiber filaments. The fiber filaments rotate, and the first exhaust fan 14 extracts the hot air in the upper part of the shell 1 through the exhaust pipe 16, and then transports the hot air to the mounting rings 3 on both sides through the return air pipe 15. The hot air in the mounting ring 3 enters the lifting box 7 through the air duct 9 and the connecting hose 10, and then the hot air is sprayed to the surface of the polyimide fiber filaments through the outlet pipe 8, and the outlet pipe 8 rotates around the polyimide fiber filaments, so that the hot air can be blown to the entire surface of the polyimide fiber filaments, and the surface of the polyimide fiber filaments can be fully heat-treated. The polyimide fiber filaments can obtain more heat through the secondary blowing and heating of the hot air, thereby improving the heat treatment effect of the polyimide fiber filaments. After the heat treatment, the static electricity of the heat-treated polyimide fiber filaments is eliminated by the static electricity elimination module 23;

[0026] When the inner cylinder 4 rotates, the cleaning component 26 is driven to rotate, so that the cleaning component 26 can rub against the surface of the polyimide fiber filaments, thereby sweeping off the dust on the surface of the polyimide fiber filaments and removing it outward, thereby ensuring the cleanliness of the surface of the polyimide fiber filaments, avoiding the dust from affecting the subsequent heat treatment of the polyimide fiber filaments, and improving the effect of the subsequent heat treatment.

[0027] In an example of this embodiment, the telescopic part is an electric telescopic rod 6, and of course it can also be other parts that can actively change the length, such as a hydraulic cylinder. The electric telescopic rod 6 drives the lifting box 7 to move, thereby adjusting the distance between the air outlet duct 8 and the polyimide fiber filaments.

[0028] like Figure 1 As shown, an intelligent heat treatment device for polyimide fiber filaments for testing provided by the utility model is provided. The power assembly 25 includes a rotating power part, which is fixedly installed on the side of the shell 1 and its output shaft extends into the shell 1. The axis of the output shaft of the rotating power part is parallel to the axis of the inner cylinder 4. A gear 12 is fixedly installed at the end of the output shaft of the rotating power part, and the gear 12 is meshed with a ring gear 13 fixedly installed at the end of the inner cylinder 4.

[0029] In actual application of this embodiment, the rotating power part drives the inner cylinder 4 to rotate through the meshing gear 12 and the ring gear 13, so that the inner cylinder 4 drives the air outlet pipe 8 to rotate around the polyimide fiber filaments, so that the hot air can cover the surface of the polyimide fiber filaments, thereby improving the effect of heat treatment.

[0030] In an example of the present invention, the rotating power component is a motor 11, and of course it can also be other components capable of outputting rotating power, such as a hydraulic motor, etc., and the motor 11 drives the inner cylinder 4 to rotate.

[0031] like Figure 1 and Figure 3 As shown, an intelligent heat treatment device for polyimide fiber filaments for testing provided by the utility model is provided, and the cleaning component 26 includes a cleaning cylinder 17, and the cleaning cylinder 17 is fixedly installed at the end of the inner cylinder 4, and the axis of the cleaning cylinder 17 is colinearly distributed with the axis of the inner cylinder 4, and the cleaning cylinder 17 is rotatably connected to a closed ring 19 fixedly installed in the shell 1, and a second exhaust fan 21 connected to the closed ring 19 is fixedly installed on the outside of the shell 1, and a cleaning brush 20 is fixedly installed in the cleaning cylinder 17, and the cleaning brush 20 is distributed along the radial direction of the cleaning cylinder 17, and a partition 18 is fixedly installed at one end of the cleaning cylinder 17 close to the inner cylinder 4.

[0032] In actual application of this embodiment, the rotation of the inner cylinder 4 drives the cleaning cylinder 17 to rotate, so that the cleaning brush 20 rotates around the polyimide fiber filaments, and then the cleaning brush 20 can sweep the dust on the surface of the polyimide fiber filaments. At the same time, the second exhaust fan 21 draws out the air in the cleaning cylinder 17, thereby removing the swept dust, improving the cleaning effect, ensuring the subsequent heat treatment effect, and reducing the number of dust particles escaping to the side of the inner cylinder 4 through the partition 18, reducing the speed of hot air escaping to the side of the cleaning cylinder 17.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
