Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot pressing technology for fiber fabrics, and in particular to a hot pressing device for fiber fabrics. Background Technology
[0002] Hot pressing of fiber fabrics is a process that combines heating and pressure to treat fiber fabrics under specific temperature and pressure conditions, causing physical or chemical changes between the fibers to achieve fabric shaping, enhanced performance, or composite molding. During hot pressing, high temperature softens the fibers or activates the adhesive, while pressure forces the fibers to adhere tightly or bonds multiple layers of materials, ultimately forming fiber products with specific shapes, structures, or functions.
[0003] Existing patent CN221235775U discloses a hot pressing device for fiber fabrics, comprising: a worktable, a column at the upper end of the worktable, a horizontal plate on one side of the column, a hydraulic push rod at the lower end of the horizontal plate, a hot pressing plate at the lower end of the hydraulic push rod, a limiting component on the surface of the worktable, and a stretching component on one side of the limiting component. This hot pressing device for fiber fabrics prevents fabric displacement during hot pressing and effectively removes wrinkles from the fabric surface. By setting the limiting component, the hot pressing plate contacts the fabric and pushes the pressing plate downwards, thereby squeezing the first spring to generate a reaction force, tightly adhering the fabric between the hot pressing plate and the pressing plate. Furthermore, because the limiting plate is U-shaped, its sides rise when the pressing plate descends, confining the fabric to the surface of the pressing plate and preventing fabric displacement during hot pressing.
[0004] In the aforementioned prior art, since the hydraulic push rod applies pressure to the center of the hot pressing plate, and the first spring also applies pressure to the center of the pressing plate, although the hot pressing plate and the area around the pressing plate can also be subjected to a certain pressure, this pressure-applying structure is prone to causing uneven pressure around the fiber fabric, thereby affecting the hot pressing effect. Utility Model Content
[0005] The purpose of this utility model is to provide a hot pressing device for fiber fabrics, which aims to solve the technical problem in the prior art where the hydraulic push rod applies pressure to the center of the hot pressing plate, and the first spring also applies pressure to the center of the plate. Although the hot pressing plate and the area around the plate can also be subjected to a certain pressure, this pressure-applying structure easily leads to uneven pressure around the fiber fabric, thus affecting the hot pressing effect.
[0006] To achieve the above objectives, this utility model employs a fiber fabric hot pressing device, comprising a hot pressing plate, multiple lifting screws, and a C-shaped frame. Threaded sleeves are provided at each of the four bottom corners of the hot pressing plate. A driven gear is provided at one end of each lifting screw. A protective cover is provided above the C-shaped frame, and a driving gear is located inside the protective cover, driven by a motor. A pressure plate is provided at the inner bottom of the C-shaped frame. The four threaded sleeves are threadedly connected to the corresponding lifting screws and fitted onto them. The hot pressing plate is located directly above the pressure plate. The multiple lifting screws are rotatably connected to the C-shaped frame and located on it. The driven gear extends into the protective cover. The driving gear meshes with the corresponding driven gear and is located between the multiple driven gears.
[0007] The number of external teeth of the driving gear is greater than the number of external teeth of the driven gear.
[0008] The C-shaped frame and the hot pressing plate are provided with multiple guide members, each guide member including a guide rod and a guide cylinder. The guide rod is fixedly connected to the C-shaped frame and located at the inner top of the C-shaped frame. The guide rod is also slidably connected to the guide cylinder and located inside the guide cylinder. The guide cylinder is fixedly connected to the hot pressing plate and located above the hot pressing plate.
[0009] The upper surface of the hot pressing plate is also evenly provided with multiple weight-adding blocks, and the multiple weight-adding blocks are respectively located between the multiple guide members.
[0010] The fiber fabric hot pressing device further includes a stretching component, which includes a C-shaped plate, an upper stretching roller, and two support blocks. Multiple springs are disposed above the C-shaped plate. A lower stretching roller is rotatably disposed between the two support blocks. Each support block has a movable groove. A sliding rod is disposed above the support block, and a fixed plate is disposed on the sliding rod between the two support blocks. The C-shaped plate is slidably connected to the corresponding sliding rod and is sleeved on the multiple sliding rods. Multiple springs abut against the lower end face of the fixed plate. The upper stretching roller is rotatably connected to the corresponding support block and is located in the movable groove between the two support blocks. The C-shaped plate also abuts against both ends of the upper stretching roller. The two support blocks are respectively disposed on one side of the C-shaped frame.
[0011] This utility model discloses a fiber fabric hot pressing device. By setting multiple lifting screws, the threaded sleeves at the four bottom corners of the hot pressing plate are threadedly connected to the corresponding lifting screws. A motor drives the drive gear to rotate, and the drive gear meshes with multiple driven gears, thereby driving the multiple lifting screws to rotate synchronously. This allows the hot pressing plate to smoothly lift and lower, applying pressure to the fiber fabric. This multi-point support and pressure application method avoids the problem of uneven pressure distribution around the perimeter caused by applying pressure only in the center. Furthermore, multiple weight-adding blocks evenly distributed on the upper surface of the hot pressing plate can uniformly increase the weight of the hot pressing plate, making the pressure distribution on the fiber fabric more uniform. In addition, the device also includes a stretching component. Before hot pressing, the upper and lower stretching rollers stretch the fiber fabric, reducing fabric wrinkles and also helping to improve the uniformity of pressure on the fabric during hot pressing. Therefore, the device comprehensively solves the problem of uneven pressure around the fiber fabric affecting the hot pressing effect. Attached Figure Description

Detailed Implementation
[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0021] Please see Figures 1-6 This utility model provides a hot pressing device for fiber fabric, including a hot pressing plate 1, multiple lifting screws 2, and a C-shaped frame 3. Threaded sleeves 4 are provided at each of the four bottom corners of the hot pressing plate 1. A driven gear 5 is provided at one end of each lifting screw 2. A protective cover 6 is provided above the C-shaped frame 3, and a driving gear 7 is provided inside the protective cover 6, driven by a motor 8. A pressure plate 9 is provided at the inner bottom of the C-shaped frame 3. The four threaded sleeves 4 are threadedly connected to the corresponding lifting screws 2 and fitted onto them. The hot pressing plate 1 is located directly above the pressure plate 9. The multiple lifting screws 2 are rotatably connected to the C-shaped frame 3 and located on it. The driven gears 5 extend into the protective cover 6. The driving gear 7 meshes with the corresponding driven gear 5 and is located between the multiple driven gears 5.
[0022] In this embodiment, the motor 8 drives the drive gear 7 to rotate, and the drive gear 7 meshes with multiple driven gears 5 to drive multiple lifting screws 2 to rotate synchronously, so that the hot pressing plate 1 can smoothly rise and fall to apply pressure to the fiber fabric. This multi-point support and pressure method avoids the problem of uneven pressure around the fiber fabric caused by applying pressure only in the middle in the traditional method, and can make the overall pressure of the fiber fabric more uniform, thereby effectively improving the hot pressing effect and ensuring the hot pressing quality.
[0023] Furthermore, the number of external teeth of the driving gear 7 is greater than the number of external teeth of the driven gear 5.
[0024] In this embodiment, this design forms a speed-up transmission structure. When the motor 8 drives the driving gear 7 to rotate, the speed of the driven gear 5 will increase. For the lifting screw 2, it can drive the hot pressing plate 1 to move up and down more quickly, stably and powerfully, ensuring that the hot pressing plate 1 can maintain stable and sufficient pressure during the pressing process, and further improving the stability and effect of hot pressing.
[0025] Furthermore, a plurality of guide members are provided between the C-shaped frame 3 and the hot pressing plate 1. The guide members include guide rods 10 and guide cylinders 11. The guide rods 10 are fixedly connected to the C-shaped frame 3 and are located at the inner top of the C-shaped frame 3. The guide rods 10 are also slidably connected to the guide cylinders 11 and are located inside the guide cylinders 11. The guide cylinders 11 are fixedly connected to the hot pressing plate 1 and are located above the hot pressing plate 1.
[0026] In this embodiment, this structure can play a precise guiding role during the lifting and lowering of the hot pressing plate 1, preventing the hot pressing plate 1 from deviating or shaking during lifting and lowering, and ensuring that the hot pressing plate 1 always maintains a stable lifting and lowering trajectory.
[0027] Furthermore, a plurality of weight-adding blocks 12 are evenly distributed on the upper surface of the hot pressing plate 1, and the plurality of weight-adding blocks 12 are respectively located between the plurality of guide members.
[0028] In this embodiment, the weight-adding blocks 12, which are evenly distributed, can further increase the weight of the hot pressing plate 1, making the pressure distribution of the hot pressing plate 1 on the fiber fabric more uniform.
[0029] Furthermore, the fiber fabric hot pressing device also includes a stretching component, which includes a C-shaped plate 13, an upper stretching roller 14, and two support blocks 15. Multiple springs 16 are disposed above the C-shaped plate 13. A lower stretching roller 17 is rotatably disposed between the two support blocks 15. Each support block 15 has a moving groove 18. A sliding rod 19 is disposed above the support block 15, and a fixing plate 20 is disposed on the sliding rod 19 between the two support blocks 15. The C-shaped plate 13 is slidably connected to the corresponding sliding rod 19 and is sleeved on the multiple sliding rods 19. The multiple springs 16 abut against the lower end face of the fixing plate 20. The upper stretching roller 14 is rotatably connected to the corresponding support block 15 and is located within the moving groove 18 between the two support blocks 15. The C-shaped plate 13 also abuts against both ends of the upper stretching roller 14. The two support blocks 15 are respectively disposed on one side of the C-shaped frame 3.
[0030] In this embodiment, before hot pressing, the fiber fabric passes between the upper stretching roller 14 and the lower stretching roller 17. The C-shaped plate 13, under the action of the spring 16, abuts against the upper stretching roller 14, causing the upper stretching roller 14 and the lower stretching roller 17 to apply a certain pressure to the fiber fabric, thereby smoothing the fiber fabric and reducing wrinkles. This ensures that the fiber fabric is pressed more evenly during hot pressing, avoiding uneven pressure in some areas due to wrinkles, effectively improving the hot pressing effect and product quality.
[0031] When using this invention, the fiber fabric first passes through the stretching assembly located on one side of the C-frame 3. Under the action of the spring 16 and the upper stretching roller 14, and in cooperation with the lower stretching roller 17, a certain pressure is applied to the fiber fabric to stretch and flatten it, reducing wrinkles. Then, the fiber fabric is placed on the pressure plate 9 at the bottom of the C-frame 3, ensuring the fabric is flat. The motor 8 is then started, and the motor 8 drives the drive gear 7 to rotate. Since the drive gear 7 meshes with multiple driven gears 5, the driven gears 5 drive the corresponding lifting screws 2 to rotate. The threaded sleeves 4 at the four bottom corners of the hot pressing plate 1 are threadedly connected to the lifting screw 2. Under the action of the guide, the hot pressing plate 1 descends smoothly and approaches the fiber fabric. As the hot pressing plate 1 continues to descend, the weight blocks 12, which are evenly distributed on the upper surface of the hot pressing plate 1 and located between the guides, further increase the pressure, so that the hot pressing plate 1 applies pressure evenly to the stretched fiber fabric to complete the hot pressing operation. After the hot pressing is completed, the motor 8 reverses and drives the lifting screw 2 to rotate in the opposite direction, so that the hot pressing plate 1 rises smoothly and the hot-pressed fiber fabric can be taken out.
[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
