[0003] However, when heat-treating synthetic fibers, uneven temperature distribution inside the heating chamber can lead to inconsistent heat treatment effects on different parts of the synthetic fiber. Utility Model Content

[0004] The purpose of this invention is to provide a heat treatment device for synthetic fibers, so as to solve the problem mentioned in the background art that uneven temperature distribution inside the heating chamber leads to inconsistent heat treatment effects in different parts of the synthetic fibers.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat treatment device for synthetic fibers, comprising a heating chamber and a heater installed on the lower side of the heating chamber;

[0006] A radiant plate is fixedly connected to the upper outer wall of the heater to diffuse the heat emitted by the heater;

[0007] The heating chamber has an outlet and an inlet respectively on the inner side of its left and right outer walls;

[0008] The heating chamber is equipped with multiple guide rollers, and multiple fiber bodies are arranged between the multiple guide rollers;

[0009] A fixing rod is provided at the center between the inner walls of the front and rear ends of the heating chamber, and multiple stirring blades are fixedly connected at equal intervals to the circular outer walls of the left and right ends of the fixing rod.

[0010] Preferably, a second fixing seat is fixedly connected to the inner wall of the front end of the heating chamber to limit the position of the first end of the fixing rod, and a second drive motor is provided on the outer wall of the rear end of the second fixing seat to drive the fixing rod to rotate.

[0011] Preferably, both the fixing rod and the stirring blade are hollow.

[0012] Preferably, a working chamber is fixedly connected to the outer wall of the rear end of the heating chamber, and a first drive motor is fixedly connected to the inner wall of the lower end of the working chamber.

[0013] Preferably, each of the rear outer walls of the multiple guide rollers is fixedly connected to a drive shaft, and a synchronous belt is provided between the multiple drive shafts to synchronize the rotation of the multiple drive shafts.

[0017] Compared with the prior art, the present invention provides a heat treatment device for synthetic fibers, which has the following advantages:

[0018] By installing a fixed rod and stirring blades, the fixed rod rotates under the control of a second drive motor. As the fixed rod rotates, it drives the stirring blades to rotate synchronously, thereby evenly dispersing the heat inside the heating chamber. Hot air or hot medium is quickly carried to all corners by the stirring blades, making full contact with the synthetic fibers. This greatly accelerates the speed at which heat is transferred from the heating source to the synthetic fibers. The stirring blades stir the hot medium in the high-temperature area to the low-temperature area, and at the same time, they carry the medium in the low-temperature area to the high-temperature area. This effectively reduces the temperature difference in all directions, such as up and down and left and right, inside the heating chamber. After a period of stirring, the temperature inside the entire heating chamber can become more uniform, and the temperature fluctuation range can be controlled within a very small range. This ensures that the synthetic fibers receive the same degree of heating in all positions, significantly improving the stability and consistency of product quality. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-4 The heat treatment apparatus for synthetic fibers shown includes a heating chamber 1 and a heater 9 installed on the lower side of the heating chamber 1;

[0026] A radiant plate 10 is fixedly connected to the upper outer wall of the heater 9 to diffuse the heat emitted by the heater 9;

[0027] The outer walls at both ends of the heating chamber 1 are respectively provided with a discharge port 15 and a feed port 3;

[0028] The heating chamber 1 is equipped with multiple guide rollers 8, and multiple fiber bodies 6 are arranged between the guide rollers 8 to organize the synthetic fibers to be processed, ensuring the continuity and uniformity of the fiber bundles. The heater 9 is turned on, and the required heating temperature and heating time are set. The heater 9 starts working, and the heat generated is transferred to the radiation plate 10. The radiation plate 10 quickly diffuses the heat to the bottom of the heating chamber 1, causing the temperature inside the heating chamber 1 to gradually rise. The internal temperature is monitored in real time by an external temperature sensor. The external conveying equipment is started to slowly feed the synthetic fibers into the heating chamber 1 from the feed port 3. Under the guidance of the guide rollers 8, the fibers move in the heating chamber 1 according to a predetermined path. During the movement, the heat treatment process is gradually completed in the heating chamber 1. Its physical and chemical properties change as expected under the action of heat. The heat-treated synthetic fibers leave the heating chamber 1 from the discharge port 15 and are transported to the subsequent processing steps by the external conveying equipment.

[0029] A fixed rod 16 is provided at the center between the inner walls of the front and rear ends of the heating chamber 1. Multiple stirring blades 18 are fixedly connected at equal intervals to the circular outer walls of the left and right ends of the fixed rod 16. When the motor that drives the fixed rod 16 to rotate is started, the fixed rod 16 drives the stirring blades 18 to start rotating. The stirring blades 18 agitate the air in the heating chamber 1, accelerate the uniform diffusion of heat, and make the synthetic fibers evenly heated during the movement.

[0030] like Figure 4 As shown, a second fixed seat 17 is fixedly connected to the inner wall of the front end of the heating chamber 1 to limit the position of the head end of the fixed rod 16. A second drive motor 19 is provided on the outer wall of the rear end of the second fixed seat 17 to drive the fixed rod 16 to rotate. Both the fixed rod 16 and the stirring blade 18 are hollow.

[0031] The second fixed seat 17 ensures that the fixed rod 16 will not be displaced during the entire heat treatment process. The second drive motor 19 is connected to the fixed rod 16 through a shaft. When the motor starts, the rotational motion of the motor shaft is transmitted to the fixed rod 16, thereby causing the fixed rod 16 to perform circular motion at a set speed.

[0032] like Figure 1 and Figure 2 As shown, a working chamber 2 is fixedly connected to the rear outer wall of the heating chamber 1, and a first drive motor 11 is fixedly connected to the lower inner wall of the working chamber 2. Drive shafts 13 are fixedly connected to the rear outer walls of multiple guide rollers 8. A synchronous belt 14 is provided between the multiple drive shafts 13 to synchronize the rotation of the multiple drive shafts 13. The first drive motor 11 is connected to one of the drive shafts 13 to provide rotational power. Multiple first fixed seats 7 are provided on the front inner wall of the heating chamber 1 to limit the position of the guide rollers 8.

[0033] The first drive motor 11 is started, and multiple guide rollers 8 are driven to rotate synchronously through the synchronous belt 14. The synthetic fiber is introduced into the heating chamber 1 from the feed port 3. Under the guidance and drive of the guide rollers 8, the fiber moves in the heating chamber 1 along the preset path. During the conveying process, the synchronous rotation of the guide rollers 8 ensures that the fiber tension is uniform, so that it can pass through the heating chamber 1 smoothly and receive uniform heat treatment.

[0034] like Figure 1 and Figure 2 As shown, multiple heat dissipation holes 12 are provided inside the rear outer wall of the working chamber 2. A base 4 is fixedly connected to the lower outer wall of the heating chamber 1 to limit the placement of the heater 9. Inspection doors 5 are provided inside the upper outer wall of the heating chamber 1, the front outer wall of the base 4, and the rear outer wall of the working chamber 2. A reflective heat insulation layer is provided on the lower outer wall of the inspection door 5 provided inside the upper outer wall of the heating chamber 1.

[0035] The heat dissipation holes 12 utilize the principle of thermal convection, allowing hot air inside the working chamber 2 to be discharged to the external environment through these small holes. The base 4 provides a stable placement position for the heater 9. When internal components malfunction or require periodic inspection, maintenance personnel can directly enter the equipment to operate by opening the corresponding inspection door 5. The lower outer wall of the inspection door 5, located inside the upper outer wall of the heating chamber 1, is equipped with a reflective insulation layer. This reflective insulation layer can reflect most of the heat radiation back into the heating chamber 1, reducing the transfer of heat to the external environment through the inspection door 5.

[0036] The implementation principle of this embodiment is as follows: The synthetic fibers to be processed are sorted to ensure the continuity and uniformity of the fiber bundles. The heater 9 is turned on, and the required heating temperature and heating time are set. The heater 9 starts working, and the heat generated is transferred to the radiation plate 10. The radiation plate 10 quickly diffuses the heat to the bottom of the heating chamber 1, causing the temperature inside the heating chamber 1 to gradually rise. The internal temperature is monitored in real time by an external temperature sensor. The external conveying equipment is started, and the synthetic fibers are slowly fed into the heating chamber 1 from the feed port 3. Under the guidance of the guide roller 8, the fibers move in the heating chamber 1 according to a predetermined path. During the movement, the heat treatment process is gradually completed in the heating chamber 1, and its physical and chemical properties change as expected under the action of heat. The heat-treated synthetic fibers leave the heating chamber 1 from the discharge port 15 and are transported to the subsequent processing steps by the external conveying equipment. The motor that drives the fixed rod 16 to rotate is started. The fixed rod 16 drives the stirring blade 18 to start rotating. The stirring blade 18 stirs the air in the heating chamber 1, accelerates the uniform diffusion of heat, and makes the synthetic fibers uniformly heated during the movement.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
