Description

Technical Field

[0001] This utility model belongs to the technical field of spinning equipment, specifically relating to a high-temperature drying oven guide mechanism. Background Technology

[0002] After being impregnated with resin, the rope needs to be dried in a high-temperature oven. Due to space limitations, the size of the oven is limited. Guide rollers are often installed on the outer side of the oven end to change the traction direction of the rope, allowing it to proceed to the next impregnation or other processes. Since the temperature inside the oven is between 170℃ and 230℃, the rope comes into contact with the cold air outside as it passes the guide rollers and then re-enters the high-temperature oven. This alternating hot and cold environment affects the performance of the rope. Utility Model Content

[0003] The purpose of this invention is to provide a high-temperature oven guiding mechanism that solves the problem of the performance of the rope being affected by the cooling effect of the guide roller without affecting the normal traction of the rope.

[0008] Preferably, the top of the cooling box is fitted with moisture-absorbing cotton.

[0009] Preferably, a water collection tray is hung above the drive motor and below the cooling pipe.

[0010] Compared with the prior art, the beneficial effect of this utility model is that by adding an insulation box to the end of the existing oven, the guide roller is installed inside the insulation box, and one end of the rotating shaft passes through the insulation box and connects to the drive motor. The drive motor drives the guide roller normally outside the oven. While not affecting the guiding function of the guide roller and allowing the yarn to be normally pulled to the next process, the guide roller is partially enclosed and connected to the oven, so that the temperature of the guide roller is consistent with that of the oven, thus solving the problem that the yarn's performance is affected after it cools down at the guide roller.

Detailed Implementation

[0012] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0013] Example 1 like Figure 1-4 As shown, the high-temperature oven guiding mechanism includes a guide roller 2 installed at the end of the oven 1, an insulation box 3 installed on the outside of the guide roller 2, an opening on the inside of the insulation box 3 and welded to the end of the oven 1, and a rotating shaft 201 at one end of the guide roller 2 passing through the side wall of the insulation box 3 and connected to a drive motor 4. The drive motor 4 is installed on the oven 1 and drives the guide roller 2 normally outside the oven 1. While not affecting the guiding function of the guide roller 2 and allowing the yarn to be normally pulled to the next process, the drive motor 4 partially closes the guide roller 2 and connects it to the oven, so that the temperature of the guide roller 2 part is consistent with that of the oven, thus solving the problem that the yarn performance is affected after it is cooled at the guide roller 2.

[0014] Furthermore, the aforementioned insulated box 3 includes a connecting part 301 and an insulated part 302. The connecting part 301 is horizontal and its outer end communicates with the insulated part 302. The insulated box 3 is inverted T-shaped. The connecting part 301 is embedded inside the oven 1, and the insulated part 302 is located outside the oven 1. The connecting part and the oven have sufficient contact area to maintain the overall stability of the insulated box. The insulated part is equipped with guide rollers and has sufficient space to guide the traction rope. Two insulated doors are opened on the outer side of the insulated part 302. 303, the outer side of the insulation door 303 is hinged to the side wall of the insulation part 302, and the insulation door 303 can be opened to check the condition of the rope at the guide roller 2. The inner side of the insulation door 303 is provided with connecting plates 304 at the top and bottom. The insulation part 302 is provided with fixing plates 305 corresponding to the connecting plates 304 at the top and bottom. The connecting plates 304 and fixing plates 305 are respectively provided with connecting holes. After the insulation door 303 is closed, the fixing plate 305 and the connecting plate 304 are connected by connecting pins 306 through the connecting holes.

[0015] A bearing seat 5 is installed on the side wall of the insulation box 3. The rotating shaft 201 is rotatably connected to the bearing seat 5 and is connected to the output shaft of the drive motor 4 through the bearing seat 5. The part of the rotating shaft 201 that extends out of the insulation box 3 is fitted with a cylindrical tube 6. Insulation mud 7 is provided between the outer wall of the cylindrical tube 6 and the side wall of the insulation box 3 to prevent the temperature at the rotating shaft from being lost, and at the same time to avoid the high temperature from affecting the drive motor.

[0016] To ensure the normal operation of the drive motor 4 and avoid damage to the motor due to high temperature, a cooling box 8 is provided below the drive motor 4. The cooling box 8 has an inlet on one side bottom for inlet to receive coolant and an outlet on the other side bottom for outlet to discharge coolant.

[0017] The top of the cooling box 8 is fitted with a moisture-absorbing cotton 10, and a water receiving tray 11 is provided above the cooling box. The water receiving tray 11 is hung on the cooling pipe 9. When the hot air around the drive motor 4 comes into contact with the cooling pipe 9, it liquefies upon contact with the cooling pipe 9 and forms water droplets that adhere to the outer wall of the cooling pipe 9. The water on the cooling pipe on the side of the drive motor falls down the cooling pipe 9 and is absorbed by the moisture-absorbing cotton. The water droplets on the cooling pipe above the drive motor 4 fall into the water receiving tray 11 to prevent water accumulation from damaging the drive motor 4.
