[0002] In many industrial production sectors, such as textiles, papermaking, and plastics processing, embossing is required to improve the appearance, increase friction, and enhance the added value of materials. Traditional embossing devices typically employ fixed-structure pressure roller assemblies with non-adjustable distances between the pressure rollers and the embossing rollers. This makes it difficult to achieve ideal embossing results when processing materials of varying thicknesses and materials. For thinner materials, if the distance between the pressure rollers and the embossing rollers is too small, the material may be excessively compressed and deformed, affecting its flatness and quality. Conversely, for thicker materials, if the distance is too large, the required embossing depth and effect may not be achieved. Utility Model Content

[0019] 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.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-5 This utility model provides an embossing device with an adjustable pressure roller assembly, including a base 1. A first bracket 2 and a drive motor 4 are fixedly installed in the middle of the base 1. An embossing roller 3 is installed on the top of the first bracket 2 through a bearing seat. The output shaft of the drive motor 4 is connected to one end of the embossing roller 3 through a transmission mechanism 5. A second bracket 6 is also fixedly installed on the base 1 outside the first bracket 2. An adjusting plate 7 is provided on the inner side of the second bracket 6. L-shaped connecting plates 8 are fixedly connected to both ends of the adjusting plate 7. The L-shaped connecting plates 8 are fixedly connected to the second bracket 6 through locking bolts 9. The second bracket 6 has a waist-shaped hole 10 corresponding to the locking bolt 9. A pressure roller 11 is installed on the bottom surface of the adjusting plate 7 through a bearing seat. The pressure roller 11 is located directly above the embossing roller 3. Motor boxes 12 are fixedly installed on both sides of the base 1. An unwinding roller 13 and a take-up roller 14 are fixedly installed on the output parts of the two motor boxes 12, respectively.

[0022] The adjustable pressure roller assembly's embossing device adjusts the position of the pressure roller 11 by using an adjustable pressure roller assembly, specifically by adjusting the position of the adjusting plate 7 through the cooperation of the L-shaped connecting plate 8, locking bolt 9, and oblong hole 10. This allows for flexible adjustment of the distance between the pressure roller 11 and the embossing roller 3 according to different materials and embossing requirements, ensuring a good embossing effect. Simultaneously, the drive motor 4 drives the embossing roller 3 to rotate through the transmission mechanism 5, which, together with the motor housing 12, drives the unwinding roller 13 and the rewinding roller 14 to achieve continuous embossing of materials, improving production efficiency and ease of operation.

[0023] The aforementioned transmission mechanism 5 includes a drive sprocket 501, a driven sprocket 502, and a transmission chain 503. The drive sprocket 501 is fixedly mounted on the output shaft of the drive motor 4, and the driven sprocket 502 is fixedly mounted on one end of the embossing roller 3. The drive sprocket 501 is connected to the driven sprocket 502 through the transmission chain 503. The chain drive method has the advantages of smooth transmission, accurate transmission ratio, large power transmission, and strong overload capacity. It can reliably transmit the power of the drive motor 4 to the embossing roller 3, ensuring the stable rotation of the embossing roller 3 and meeting the power requirements of the embossing operation.

[0024] Two symmetrically arranged threaded rods 15 are fixedly connected to the top surface of the adjusting plate 7. The threaded rods 15 are fixedly connected to the second bracket 6 by two locking nuts 16. The cooperation of the threaded rods 15 and the locking nuts 16 further enhances the connection stability between the adjusting plate 7 and the second bracket 6. Combined with the fixing method of the L-shaped connecting plate 8 and the locking bolts 9, a double fixing structure is formed, which effectively prevents the adjusting plate 7 from shaking or shifting during operation, ensuring the accuracy and stability of the pressure roller 11 position, thereby improving the embossing quality.

[0025] Two third supports 17 symmetrically arranged on both sides of the first support 2 are also fixedly installed on the base 1. The top of each of the two third supports 17 is equipped with a guide roller 18 through a bearing seat. The guide roller 18 can guide the material entering and leaving the embossing area, so that the material remains flat and stable during the conveying process, avoiding problems such as wrinkles and deviations. This ensures that the material can accurately enter between the embossing roller 3 and the pressure roller 11 for embossing, improving the accuracy and quality of embossing, while also reducing the wear and damage of the material during the conveying process.

[0026] Fixed limiting plates 19 are fixedly connected to the ends of the unwinding roller 13 and the take-up roller 14 near the motor housing 12, and movable limiting plates 20 are movably connected to the ends away from the motor housing 12. The cooperation of the fixed limiting plates 19 and the movable limiting plates 20 can limit the material cylinder on the unwinding roller 13 and the take-up roller 14, ensuring good unwinding and take-up quality. A fixed sleeve 21 is fixedly connected to the movable limiting plate 20. The fixed sleeve 21 is fixedly connected to the unwinding roller 13 or the take-up roller 14 by locking screws 22. The position of the movable limiting plate 20 can be quickly and accurately adjusted according to the actual width of the material cylinder and fixed by locking screws 22. It also facilitates the disassembly and assembly of the movable limiting plate 20 and the quick loading and unloading of the material cylinder.

[0027] When using the embossing device of this adjustable pressure roller assembly, a material cylinder containing the material to be embossed and an empty material cylinder are installed on the unwinding roller 13 and the take-up roller 14. The position of the movable limiting plate 20 is adjusted according to the width of the material cylinder, ensuring that the movable limiting plate 20 and the fixed limiting plate 19 are tightly fitted to both ends of the material cylinder. Then, the fixed sleeve 21 and the movable limiting plate 20 are fixed to the unwinding roller 13 and the take-up roller 14 using the locking screws 22. The material is then drawn from the material cylinder on the unwinding roller 13, passes sequentially around the embossing roller 3 and the two guide rollers 18, and is then fixed to the material cylinder on the take-up roller 14. Depending on the thickness of the material and the required embossing depth, the locking bolts 9 and the locking nuts 16 are loosened. The position of the adjusting plate 7 is adjusted by adjusting the waist-shaped hole 10, thereby changing the distance between the pressure roller 11 and the embossing roller 3. After adjusting to the appropriate position, the locking bolt 9 and the locking nut 16 are tightened to fix the adjusting plate 7 on the second bracket 6. Finally, the drive motor 4 and the motor box 12 are started. The drive motor 4 drives the drive sprocket 501 to rotate. The drive sprocket 501 drives the driven sprocket 502 to rotate through the transmission chain 503, thereby causing the embossing roller 3 to rotate. The motor box 12 drives the unwinding roller 13 and the take-up roller 14 to rotate. The material cylinder on the unwinding roller 13 releases the material. The material is embossed under the squeezing action of the embossing roller 3 and the pressure roller 11. The embossed material is wound and collected by the material cylinder on the take-up roller 14.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
