Description

Technical Field

[0001] This utility model relates to the field of FDY yarn processing technology, specifically to an FDY hot roller box insulation device. Background Technology

[0002] The FDY hot roller box plays a crucial role in the FDY spinning process. It primarily uses hot rollers to heat and stretch polyester and other polymer filaments, making the molecular chains of the filaments more regularly oriented, thereby improving the physical properties of the filaments, such as strength and modulus. The hot roller box typically contains heating devices and high-precision rollers. By precisely controlling the temperature and speed of the hot rollers, effective processing of the filaments is achieved. FDY hot roller boxes are often used in conjunction with insulation devices to ensure the internal temperature remains at the operating temperature. The insulation device also reduces heat loss, thus ensuring temperature stability and facilitating the operation of the FDY hot roller box.

[0003] Existing insulation devices mostly use insulation materials to wrap the device for cooling during operation. However, the insulation materials will wear out over time, resulting in reduced insulation performance and failing to meet people's needs. To address this issue, we will innovate the technology based on the existing FDY hot roller box insulation device. Utility Model Content

[0004] The purpose of this utility model is to provide an FDY hot roller box insulation device to solve the problem mentioned in the background art that the general devices cannot well meet people's usage needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an FDY hot roller box insulation device, comprising an FDY hot roller box assembly and an insulation assembly, wherein an insulation layer is installed inside the FDY hot roller box assembly, and the insulation assembly is installed inside the insulation layer. The insulation assembly comprises a first metal plate, a support block, a second metal plate, and a heat insulation connecting plate, wherein the upper end of the first metal plate is connected to the support block, the upper end of the support block is provided with the second metal plate, and the front and rear sides of the second metal plate are connected to the heat insulation connecting plates.

[0006] Furthermore, the FDY hot roller box assembly includes a box body and an air isolation layer, and the air isolation layer is provided inside the box body.

[0007] Furthermore, opening and closing control components are installed on the left and right sides of the insulation layer, and the insulation layer is in close contact with the insulation components.

[0008] Furthermore, the insulation component is equipped with an anti-collision pad inside, and the anti-collision pad completely encloses the interior of the insulation component.

[0009] Furthermore, the opening and closing control component includes a helium gas containment box and a thermally conductive metal sheet, and the thermally conductive metal sheet is installed on the side of the helium gas containment box away from the insulation component.

[0010] Furthermore, the opening and closing control assembly also includes a lifting sleeve, an upgrading rod, and a piston block, and the lifting sleeve is installed at the upper end of the helium containment box, the upgrading rod is installed inside the lifting sleeve, and the piston block is connected inside the upgrading rod.

[0011] Furthermore, the opening and closing control assembly also includes a fixed plate and a lifting plate, and the upper end of the upgrading rod is externally connected to the fixed plate, while the upper end of the upgrading rod is connected to the lifting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The equipment adopts vacuum insulation, which can keep the insulation effect constant before damage, thus facilitating the constant temperature inside the FDY hot roller box. The equipment can control the internal and external heat conduction according to the external temperature, thereby adjusting the insulation method according to the internal and external temperatures to maintain the best insulation effect of the equipment.

[0013] 1. This utility model achieves thermal insulation through the vacuum between the first metal plate and the second metal plate. The vacuum environment has excellent thermal insulation properties. At the same time, since the equipment adopts vacuum thermal insulation, as long as the first metal plate and the second metal plate are made of corrosion-resistant metals, the thermal insulation life of the equipment can be maintained for a long period of time, so that the thermal insulation effect of the equipment is always in good condition and there will be no reduction in effect due to long-term use.

[0014] 2. This utility model uses a heat-conducting metal sheet to contact the external environment. When the external temperature rises, the gas inside the helium containment box expands, causing the piston block to rise inside the lifting sleeve and push the lifting plate upward. This increases the distance between the fixed plate and the lifting plate, making it easier for the first metal plate to absorb the external temperature, thereby reducing the temperature difference between the first and second metal plates and reducing temperature leakage. Conversely, when the external temperature drops, the insulation layer is sealed to reduce temperature leakage. Attached Figure Description

[0019] like Figure 2 As shown, an FDY hot roller box insulation device includes an FDY hot roller box assembly 1 and an insulation assembly 4. An insulation layer 3 is installed inside the FDY hot roller box assembly 1, and the insulation assembly 4 is installed inside the insulation layer 3. The insulation assembly 4 includes a first metal plate 401, a support block 402, a second metal plate 403, and a heat insulation connecting plate 404. The upper end of the first metal plate 401 is connected to the support block 402, the upper end of the support block 402 is provided with the second metal plate 403, and the front and rear sides of the second metal plate 403 are connected to the heat insulation connecting plate 404.

[0020] Thermal insulation is achieved through a vacuum between the first metal plate 401 and the second metal plate 403. The vacuum environment has excellent thermal insulation properties. Since the equipment uses vacuum insulation, as long as the first metal plate 401 and the second metal plate 403 are made of corrosion-resistant metals, the insulation life of the equipment can be maintained for a long period of time, so that the insulation effect of the equipment is always in good condition and will not decrease due to long-term use.

[0021] like Figure 1 As shown, the FDY hot roller box assembly 1 includes a box body 101 and an air isolation layer 102, and the air isolation layer 102 is provided inside the box body 101.

[0022] The air isolation layer 102 inside the enclosure 101 can reduce the contact between the enclosure 101 and the insulation layer 3, thereby reducing temperature transfer.

[0023] like Figure 1 and Figure 2 As shown, opening and closing control components 2 are installed on the left and right sides of the insulation layer 3, and the insulation layer 3 is closely attached to the insulation component 4. The insulation component 4 is provided with anti-collision pads 5 inside, and the anti-collision pads 5 completely wrap the inside of the insulation component 4.

[0024] The anti-collision pad 5 protects the second metal plate 403, so that the FDY hot roller box will not collide with and damage the second metal plate 403 during operation, and the insulation layer 3 can achieve a secondary insulation effect.

[0025] like Figure 3As shown, the opening and closing control component 2 includes a helium gas containment box 201 and a heat-conducting metal sheet 202. The heat-conducting metal sheet 202 is installed on the side of the helium gas containment box 201 away from the heat insulation component 4. The opening and closing control component 2 also includes a lifting sleeve 203, an upgrading rod 204 and a piston block 205. The lifting sleeve 203 is installed at the upper end of the helium gas containment box 201. The upgrading rod 204 is installed inside the lifting sleeve 203. The piston block 205 is connected inside the upgrading rod 204. The opening and closing control component 2 also includes a fixing plate 206 and a lifting plate 207. The fixing plate 206 is connected to the upper external end of the upgrading rod 204. The lifting plate 207 is connected to the upper end of the upgrading rod 204.

[0026] By having the thermally conductive metal sheet 202 come into contact with the external environment, the gas inside the helium containment box 201 can expand when the external temperature rises, causing the piston block 205 to rise inside the lifting sleeve 203 and push the lifting plate 207 upward. This increases the distance between the fixed plate 206 and the lifting plate 207, making it easier for the first metal plate 401 to absorb the external temperature, thereby reducing the temperature difference between the first metal plate 401 and the second metal plate 403 and reducing temperature leakage. Conversely, when the external temperature decreases, the insulation layer 3 is sealed to reduce temperature leakage.

[0027] Working principle: When using the FDY hot roller box insulation device, firstly, the opening and closing control component 2 is embedded in the lower left and right sides of the air isolation layer 102. Then, the insulation component 4 wrapped with the insulation layer 3 is placed into the equipment. At this time, a slit is made in the middle of the insulation layer 3. The lower part of the slit is connected to the lower part of the fixing plate 206, and the upper part of the slit is connected to the upper part of the lifting plate 207, thus completing the installation of the equipment.

[0028] During equipment use, the anti-collision pad 5 protects the second metal plate 403, so that the FDY hot roller box will not collide with and damage the second metal plate 403 during operation. This ensures that the vacuum environment between the second metal plate 403 and the first metal plate 401 is maintained, thereby ensuring the thermal insulation performance of the insulation component 4. The thermal insulation connecting plate 404 can connect the front and rear of the second metal plate 403 and the first metal plate 401, thereby completely sealing them. At the same time, the thermal insulation connecting plate 404 can also reduce the temperature transfer between the second metal plate 403 and the first metal plate 401.

[0029] The device comes into contact with the external environment through the thermally conductive metal sheet 202. When the external temperature rises, the gas inside the helium containment box 201 expands, causing the piston block 205 to rise inside the lifting sleeve 203. This causes the upgrading rod 204 to extend from inside the lifting sleeve 203 and push the lifting plate 207 upward, thereby increasing the distance between the fixed plate 206 and the lifting plate 207. This facilitates the absorption of external temperature by the first metal plate 401, thereby reducing the temperature difference between the first metal plate 401 and the second metal plate 403 and reducing temperature leakage. Conversely, when the external temperature decreases, the insulation layer 3 is sealed to reduce temperature leakage.
