Description

Technical Field

[0001] The present invention belongs to the field of textile technology, and in particular relates to a flame-retardant fiber for imitation wood grain decorative materials and a preparation device thereof. Background Art

[0002] Imitation wood-grain decorative materials are widely used in interior decoration and furniture manufacturing due to their natural, aesthetically pleasing appearance and environmentally friendly properties. To enhance the flame retardancy of these materials, the fiber material is typically impregnated with a flame retardant and then dried before being laminated with the decorative surface. This allows the flame retardant to adhere to the fiber surface. Workers then adhere the wood-grain decorative surface to create the imitation wood-grain decorative material.

[0003] Current flame-retardant fiber materials have low structural strength during actual use, making them susceptible to damage from foreign matter or sharp objects, thus shortening their service life. Furthermore, during the fiber drying process, the heat source is fixed in position, and different fiber types require different drying temperatures. Adjusting the heat source's output power can lead to poor drying results, thus impacting subsequent processing steps. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies in the prior art and provide a flame-retardant fiber for imitation wood grain decorative materials having high structural strength, good flame retardancy and good preparation effect, and a preparation device thereof.

[0005] In order to achieve the above technical objectives, the flame-retardant fiber for imitation wood grain decorative material and the preparation device thereof of the present invention adopt the following technical solutions: A flame-retardant fiber for wood-grain imitation decorative materials comprises a base layer, a flame-retardant layer provided on both sides of the base layer, a modified layer provided on the side of each flame-retardant layer facing away from the base layer, a decorative layer provided on the side of the modified layer facing away from the flame-retardant layer, the modified layer comprising a glass fiber layer and an aluminum silicate refractory fiber layer, one side of the glass fiber layer being connected to the flame-retardant layer and the other side being connected to the aluminum silicate refractory fiber layer, and the side of the aluminum silicate refractory fiber layer facing away from the glass fiber layer being connected to the decorative layer. The glass fiber layer and the aluminum silicate refractory fiber layer, in combination with the flame-retardant layer, enhance the overall structural strength of the fiber material and improve its overall flame-retardant properties, thereby extending the service life of the fiber material.

[0006] A flame-retardant fiber preparation device for imitation wood grain decorative materials includes a transition box and an oven, the transition box and the oven being connected, the transition box being provided with an extrusion assembly for extruding fiber materials, the oven being provided with a lifting assembly and a drying assembly, the lifting assembly including a lifting frame and a support roller, the lifting frame being vertically slidably connected to the oven, the support roller being rotatably connected to the lifting frame, the lifting frame being provided with two opposing conveying rollers, the support roller being disposed between the two conveying rollers, and the drying assembly being disposed directly below the lifting frame. The extrusion assembly extrudes excess flame retardant from the fiber material, and the fiber material then enters the oven, passing through a conveying roller, a support roller, and another conveying roller in sequence. The lifting frame then controls the positions of the conveying roller and the support roller to adjust the position between the fiber material and the drying assembly, so that the fiber material is located within a suitable temperature range, allowing the drying assembly to more stably dry the fiber material tank, thereby improving the preparation effect of the preparation device on the fiber material.

[0007] Preferably, the lifting frame is rotatably connected to two opposing adjustment frames, one for each conveyor roller. The conveyor rollers are rotatably connected to the corresponding adjustment frames, and the lifting frame is equipped with locking members for locking the adjustment frames. A worker rotates the adjustment frames based on the desired retention time of the fiber material, which in turn rotates the conveyor rollers to adjust the distance between them and the support rollers. This allows for adjustment of the inclination angle of the fiber material between the conveyor rollers and the support rollers, increasing the drying area of ​​the fiber material within the drying assembly, allowing the drying assembly to adapt to the varying drying requirements of the fiber material, thereby further improving the fiber material preparation efficiency of the preparation device.

[0008] Preferably, the locking member includes a locking rod and a nut, wherein the locking rod is connected to the rotating shaft of the adjustment frame, and the nut is threadedly connected to the locking rod, and the nut is tightly abutted against the lifting frame. After the position of the adjustment frame is adjusted, the worker rotates the nut so that the nut is tightly abutted against the lifting frame, thereby fixing the position of the adjustment frame.

[0009] Preferably, the rotating shaft of the adjustment frame extends beyond the lifting frame and is connected to an indicator rod, the indicator rod being provided with a scale block, and the lifting frame being provided with a scale meter that cooperates with the scale block. During rotation of the adjustment frame, the adjustment frame drives the indicator rod and the scale block to rotate, and the scale block cooperates with the scale meter, making it convenient for workers to observe the degree of inclination of the adjustment frame, so that the position of the adjustment frame can be adapted to the drying requirements of different fiber materials.

[0010] Preferably, the drying assembly includes a plurality of support rods, and each of the support rods is wound with a heating wire.

[0011] Preferably, the extrusion assembly includes two oppositely disposed extrusion rollers, each of which is rotatably connected to a transition box. The transition box is provided with a drive member for driving the two extrusion rollers in opposite directions. The drive member controls the two extrusion rollers to rotate in opposite directions, thereby facilitating the conveyance of the fiber material and facilitating the extrusion of the fiber material to squeeze out excess flame retardant.

[0012] Preferably, a waste box is provided in the transition box, which is convenient for collecting excess flame retardant.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention improves the overall structural strength of the fiber material and the overall flame retardant performance of the fiber material by providing a glass fiber layer, an aluminum silicate refractory fiber layer and a flame retardant layer, thereby extending the service life of the fiber material. 2. The present invention provides a lifting assembly to facilitate adjustment of the position of the fiber material and the drying assembly in the oven, so that the drying assembly can dry the fiber material more stably, keeping the fiber material within a suitable temperature range, thereby improving the preparation effect of the preparation device on the fiber material; 3. The present invention provides an adjustable adjustment frame to adjust the position between the conveying roller and the support roller, thereby adjusting the area of ​​the fiber material between the conveying roller and the support roller, thereby increasing or shortening the time that the fiber material is in the appropriate temperature area, thereby further improving the preparation effect of the preparation equipment on the fiber material.

DETAILED DESCRIPTION

[0016] The invention is further described below with reference to the accompanying drawings and specific embodiments: like Figure 1 — Figure 3 As shown, a flame retardant fiber for imitation wood grain decorative materials. Figure 1 A flame-retardant fiber for wood-grain imitation decorative materials comprises a base layer 1, with flame-retardant layers 2 disposed on both sides of the base layer 1. Each flame-retardant layer 2 is provided with a modified layer 3 on the side facing away from the base layer 1, and a decorative layer 4 is provided on the side facing away from the flame-retardant layer 2. The base layer 1 is woven from cotton, and the flame-retardant layers 2 are formed by impregnation with a flame-retardant solvent, which is a mixture of pentaerythritol phosphate and melamine, followed by drying.

[0017] Reference Figure 1 The modified layer 3 includes a glass fiber layer 31 and an aluminum silicate refractory fiber layer 32. One side of the glass fiber layer 31 is connected to the flame-retardant layer 2, and the other side is connected to the aluminum silicate refractory fiber layer 32. The side of the aluminum silicate refractory fiber layer 32 facing away from the glass fiber layer 31 is connected to the decorative layer 4. The decorative layer 4 is provided as a water-based polyurethane coating and is integrated onto the aluminum silicate refractory fiber layer 32 via a hot pressing process. The glass fiber layer 31 increases the structural strength of the fiber material as a whole, making it less susceptible to external damage and thus extending the service life of the fiber material as a whole.

[0018] The implementation principle of the embodiment of the present application is: the flame retardant layer 2, the glass fiber layer 31 and the aluminum silicate refractory fiber layer 32 formed after impregnation with the flame retardant are coordinated, which on the one hand improves the overall structural strength of the fiber material, and on the other hand improves the overall flame retardant performance of the fiber material, thereby extending the service life of the fiber material.

[0019] In a second aspect, the embodiments of the present application also disclose a preparation device.

[0020] Reference Figure 2The preparation device includes a transition box 5 and an oven 6. The transition box 5 and the oven 6 are connected. The transition box 5 is provided with an extrusion assembly 51 for extruding fiber materials. The oven 6 is provided with a lifting assembly 7 and a drying assembly 8. The lifting assembly 7 includes a lifting frame 71 and a support roller 72. The lifting frame 71 is slidably connected in the oven 6 along the vertical direction. The support roller 72 is rotatably connected to the lifting frame 71. The lifting frame 71 is provided with two opposing conveying rollers 73, and the conveying rollers 73 are rotatably connected to the lifting frame 71. The support roller 72 is arranged between the two conveying rollers 73. The oven 6 is provided with a cylinder 61. The output end of the cylinder 61 extends into the oven 6 and is connected to the lifting frame 71. The drying assembly 8 is arranged directly below the lifting frame 71.

[0021] The cylinder 61 facilitates adjustment of the positions of the lifting frame 71, the support roller 72 and the conveying roller 73 to adjust the position between the fiber material and the drying component 8 so that the fiber material is in a suitable temperature range, so that the drying component 8 can dry the fiber material more stably, thereby improving the preparation effect of the preparation device on the fiber material.

[0022] Reference Figure 2 and Figure 3 To facilitate conveying the fiber material, the extrusion assembly 51 includes two opposing extrusion rollers 511, both rotatably connected to the transition box 5. The transition box 5 is equipped with a drive element for driving the two extrusion rollers 511 in opposite directions. The rotating shafts of the two extrusion rollers 511 extend out of the transition box 5 and are connected to gears 512, with adjacent gears 512 meshing with each other. The drive element includes a motor 52, which is mounted on the transition box 5, with the output end of the motor 52 connected to one of the gears 512.

[0023] The motor 52 controls the corresponding gear 512 to rotate, and the gear 512 drives the adjacent gear 512 to rotate, causing the two adjacent squeezing rollers 511 to rotate in opposite directions. At this time, the two squeezing rollers 511 squeeze the fiber material to squeeze out excess flame retardant, and at the same time facilitate the transportation of the fiber material.

[0024] Reference Figure 2 The transition box 5 is equipped with a waste bin 53 and a guide ramp 531. After extrusion, excess flame retardant is transported through the guide ramp 531 to the waste bin 53 for collection. A first guide roller 54 is rotatably connected to the side of the transition box 5 facing away from the drying oven 6. This first guide roller 54 guides the fiber material for delivery to the extrusion assembly 51.

[0025] A guide plate 55 is provided in the transition box 5 , which facilitates the collection of dripping flame retardant, and the end of the guide plate 55 close to the oven 6 is tilted toward the waste box 53 to guide the collected flame retardant into the waste box 53 .

[0026] Reference Figure 2 A second guide roller 62 and a third guide roller 63 are rotatably connected in the oven 6, and a lifting frame 71 is located between the second guide roller 62 and the third guide roller 63. The second guide roller 62 facilitates guiding the fiber material to the lifting frame 71, and the third guide roller 63 facilitates leading the fiber material out of the oven 6.

[0027] Reference Figure 2 and Figure 4 The lifting frame 71 is rotatably connected to two opposite adjustment frames 74 , and each conveying roller 73 corresponds to one adjustment frame 74 , and the conveying roller 73 is rotatably connected to the adjustment frame 74 at the corresponding position.

[0028] Reference Figure 3 The lifting frame 71 is provided with a locking member for locking the adjusting frame 74. The locking member includes a locking rod 75 and a nut 751. The locking rod 75 is connected to the rotating shaft of the adjusting frame 74. The nut 751 is threadedly connected to the locking rod 75. The nut 751 is tightly pressed against the lifting frame 71.

[0029] The worker rotates the adjustment frame 74 according to the desired retention time of the fiber material. The adjustment frame 74 drives the conveyor roller 73 to rotate, thereby adjusting the distance between the conveyor roller 73 and the support roller 72. This allows the inclination angle of the fiber material between the conveyor roller 73 and the support roller 72 to be adjusted, thereby increasing the drying area of ​​the fiber material for the drying assembly 8, allowing the drying assembly 8 to adapt to the different drying requirements of the fiber material, thereby further improving the preparation effect of the preparation device on the fiber material.

[0030] After the position adjustment of the adjustment frame 74 is completed, the worker rotates the nut 751 so that the nut 751 is tightly pressed against the lifting frame 71 , thereby completing the fixing of the position of the adjustment frame 74 .

[0031] Reference Figure 4 To improve the positioning accuracy of the adjustment frame 74, the rotating shaft of the adjustment frame 74 extends beyond the lifting frame 71 and is connected to an indicator rod 741. A scale block 742 is fixed to the indicator rod 741, and the lifting frame 71 is equipped with a scale gauge 711 that cooperates with the scale block 742. As the adjustment frame 74 rotates, it drives the indicator rod 741 and the scale block 742 to rotate. The scale block 742 cooperates with the scale gauge 711, making it easier for workers to observe the tilt of the adjustment frame 74, so that the position of the adjustment frame 74 can be adapted to the drying requirements of different fiber materials.

[0032] Reference Figure 2The drying assembly 8 includes a plurality of support rods 81 , each of which is wound with a heating wire 82 . The heating wire 82 facilitates drying the fiber material so that the flame retardant adheres to the fiber material.

[0033] The working principle of the embodiment of the present application is as follows: the extrusion assembly 51 squeezes the excess flame retardant from the fiber material, and the fiber material then enters the drying oven 6. The fiber material sequentially passes through a conveyor roller 73, a support roller 72, and another conveyor roller 73. The lifting frame 71 then controls the position of the conveyor roller 73 and the support roller 72 to adjust the position between the fiber material and the drying assembly 8, so that the fiber material is located in a suitable temperature range, allowing the drying assembly 8 to dry the fiber material more stably, thereby improving the preparation effect of the preparation device on the fiber material.

[0034] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. All equivalent changes and modifications in the shape, structure, characteristics and spirit of the claims of the present invention should be included in the scope of the claims of the present invention.
