[0002] Embossing machines are equipment used for surface processing of paper products. Embossing can enhance the aesthetics and decorative effects of products, thereby improving their quality. Embossing machines are often used to emboss when producing art cardstock.

[0003] For example, the patent with application number 202321652941.4 discloses an embossing device for anti-counterfeiting cardboard. Currently used embossing devices have embossing protrusions that are directly integrated onto the pressure roller and cannot be disassembled. After long-term use, these embossing protrusions are prone to deformation due to compression, requiring replacement. However, when replacing them, the entire pressure roller must be replaced, increasing the cost of use. Summary of the Invention

[0004] This utility model provides an embossing machine in which, when the raised part on the embossing strip is deformed and needs to be replaced, there is no need to replace the pressure roller and the receiving roller. Only the embossing strip needs to be disassembled and replaced separately. Moreover, the disassembly operation is very inconvenient, effectively reducing the cost of use.

[0008] In at least some embodiments, the outer sides of both the receiving roller and the pressure roller are provided with twelve elongated grooves arranged in a ring, and the dimensions of the embossed strips and the smooth strips are equal to the dimensions of these elongated grooves.

[0009] In at least some embodiments, the annular grooves at both ends of the receiving roller and the pressure roller are also provided with twelve circular holes of the same size as the positioning rods, and after the positioning ring of the clip is rotated 15°, the positioning rod on one side can be inserted into the circular holes on one side of the annular grooves at both ends of the receiving roller and the pressure roller.

[0010] In at least some embodiments, an annular groove is provided on the outer sides of both ends of the receiving roller and the pressure roller, and the positioning ring of the clip can slide left and right in this annular groove, and the outer diameter of the positioning ring of the clip is equal to the outer diameter of the main body of the receiving roller and the pressure roller.

[0011] In at least some embodiments, a layer of rubber can be pasted in the elongated groove on the outer side of the receiving roller and the pressure roller, and a layer of rubber can also be wrapped on the outer side wall of the embossed strip and the smooth strip that contact the inner wall of the elongated groove.

[0012] In at least some embodiments, both the left and right ends of the embossed strip and the smooth strip are provided with a circular hole of the same size as the positioning rod, and after the embossed strip and the smooth strip are installed, the positioning rod can be inserted into the circular holes at both ends.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] This utility model proposes an embossing machine, including: a mounting base 1;

[0029] A receiving roller 2 is rotatably mounted inside the mounting base 1. The mounting base 1 supports the rotation of the receiving roller 2 and the pressure roller 3. When embossing the cardboard, the receiving roller 2 and the pressure roller 3 can rotate stably under the support of the mounting base 1. During the embossing process, the receiving roller 2 can support the cardboard from the bottom. At the same time, the embossing strips 4 on the receiving roller 2 and the embossing strips 4 on the pressure roller 3 work together to squeeze the cardboard to achieve embossing. A pressure roller 3 is also rotatably mounted inside the mounting base 1. During installation, the main shaft of an external motor can be connected to the pressure roller 3 and the receiving roller 2 for transmission. During embossing, the pressure roller 3 and the receiving roller 2 can be driven by the external motor. The receiving roller 2 rotates synchronously in opposite directions, then the cardstock to be embossed can be directly pushed towards the pressure roller 3 and the receiving roller 2. During this process, the pressure roller 3 and the receiving roller 2 cooperate to clamp the cardstock and move it. Moreover, the embossing strips 4 on the receiving roller 2 and the pressure roller 3 work together to squeeze the cardstock to achieve embossing. Six embossing strips 4 are embedded on the outer sides of both the receiving roller 2 and the pressure roller 3. During the rotation of the pressure roller 3 and the receiving roller 2, the embossing strips 4 on the receiving roller 2 and the pressure roller 3 work together to squeeze the cardstock to achieve embossing. When it is necessary to remove the embossing strips 4, they can be easily removed. When replacing the embossed strip, first push the positioning ring 6 towards both ends of the receiving roller 2 and the pressure roller 3. At this time, the positioning rod 7 on one side of the positioning ring 6 will disengage from the round holes at both ends of the embossed strip 4. Therefore, the embossed strip 4 can be pried out of the elongated groove on the outside of the receiving roller 2 and the pressure roller 3 for removal. When installing the embossed strip 4, simply insert it into the elongated groove on the outside of the pressure roller 3 and the receiving roller 2. Then, push the positioning ring 6 back towards both ends of the pressure roller 3 and the receiving roller 2 and rotate it 15°. At this time, the positioning rod 7 on the positioning ring 6 will align with the round holes at both ends of the embossed strip 4. Then, the embossed strip can be installed. When the positioning ring 6 is released, the magnetic plates at both ends of the receiving roller 2 and the pressure roller 3 will push the positioning ring 6 of the card strip to slide toward the middle position of the receiving roller 2 and the pressure roller 3. Then, the positioning round rod 7 will be embedded in the round holes at both ends of the embossing card strip 4, thereby locking the position of the embossing card strip 4. Six smooth card strips 5 are also embedded and installed on the outer side of the receiving roller 2 and the pressure roller 3. After the smooth card strips 5 are installed at equal intervals, the spacing of the embossing of the embossing card strip 4 can be increased. In use, the smooth card strips 5 can be selectively installed. If the required embossing is relatively dense, the smooth card strips 5 do not need to be installed. If the required embossing is dense, the smooth card strips 5 can be installed.A positioning ring 6 is slidably installed on the outer sides of both ends of the receiving roller 2 and the pressure roller 3. When reinstalling the embossed strip 4 and the smooth strip 5, the positioning ring 6 can be rotated 15° and then released. Because the positioning ring 6 repels the magnetic plates at both ends of the receiving roller 2 and the pressure roller 3, the magnetic plates at both ends of the receiving roller 2 and the pressure roller 3 will push the positioning ring 6 towards the middle position of the receiving roller 2 and the pressure roller 3. At the same time, the positioning rod 7 will be embedded in the round hole on one side of the annular groove at both ends of the receiving roller 2 and the pressure roller 3. Therefore, it will not affect the installation of the embossed strip 4 and the smooth strip 5, and there is no need to continuously push the positioning ring 6 when installing the embossed strip 4 and the smooth strip 5. Twelve positioning rods 7 are arranged in a ring on one side of the positioning ring 6. After the positioning rods 7 are embedded in the round holes at both ends of the embossed strip 4 and the smooth strip 5, they can lock the position of the embossed strip 4 and the smooth strip 5.

[0030] In this embodiment of the disclosure, such as Figures 1-6 As shown, the positioning rings 6 are all magnetic rings. Both ends of the receiving roller 2 and the pressure roller 3 are also equipped with a magnetic plate. The adjacent magnetic poles of the positioning rings 6 and the magnetic plates at both ends of the receiving roller 2 and the pressure roller 3 are the same. When reinstalling the embossed strip 4 and the smooth strip 5, the positioning rings 6 can be rotated 15° and then loosened. Because the positioning rings 6 and the magnetic plates at both ends of the receiving roller 2 and the pressure roller 3 repel each other, the magnetic plates at both ends of the receiving roller 2 and the pressure roller 3 will push the positioning rings 6 to slide toward the middle position of the receiving roller 2 and the pressure roller 3. Moreover, when the positioning rods 7 on the positioning rings 6 are used to fix the positions of the embossed strip 4 and the smooth strip 5, there will be no loosening.

[0031] In this embodiment of the disclosure, such as Figures 1-5 As shown, the outer sides of the receiving roller 2 and the pressure roller 3 are each provided with twelve long strip grooves arranged in a ring. The size of the embossed strip 4 and the smooth strip 5 is equal to the size of these long strip grooves. When installing the embossed strip 4 and the smooth strip 5, they can be embedded into the long strip grooves on the outer side of the receiving roller 2 and the pressure roller 3, and there will be no shaking after installation.

[0032] In this embodiment of the disclosure, such as Figure 4 and Figure 6As shown, twelve circular holes of the same size as the positioning rod 7 are also provided on one side of the annular grooves at both ends of the receiving roller 2 and the pressure roller 3. After the positioning ring 6 is rotated 15°, the positioning rod 7 on one side can be inserted into the circular holes on one side of the annular grooves at both ends of the receiving roller 2 and the pressure roller 3. When reinstalling the embossed strip 4 and the smooth strip 5, the positioning ring 6 can be rotated 15° and then released. Because the positioning ring 6 and the magnetic plates at both ends of the receiving roller 2 and the pressure roller 3 repel each other, the magnetic plates at both ends of the receiving roller 2 and the pressure roller 3 will push the positioning ring 6 towards the middle position of the receiving roller 2 and the pressure roller 3. At the same time, the positioning rod 7 will be inserted into the circular holes on one side of the annular grooves at both ends of the receiving roller 2 and the pressure roller 3. Therefore, it will not affect the installation of the embossed strip 4 and the smooth strip 5. When installing the embossed strip 4 and the smooth strip 5, it is not necessary to continuously push the positioning ring 6.

[0033] In this embodiment of the disclosure, such as Figures 1-6 As shown, both ends of the receiving roller 2 and the pressure roller 3 are provided with an annular groove. The card strip positioning ring 6 can slide left and right in this annular groove. The outer diameter of the card strip positioning ring 6 is equal to the outer diameter of the main body of the receiving roller 2 and the pressure roller 3. When the card strip positioning ring 6 slides left and right, the positioning rod 7 on one side will disengage from or engage with the round holes at both ends of the embossed card strip 4 and the smooth card strip 5. Therefore, the embossed card strip 4 and the smooth card strip 5 can be disassembled or fixed. Moreover, the card strip positioning ring 6 will not protrude outward, ensuring that the receiving roller 2 and the pressure roller 3 can properly squeeze the card.

[0034] In this embodiment of the disclosure, such as Figures 1-3 As shown, both ends of the embossed strip 4 and the smooth strip 5 are provided with a circular hole of the same size as the positioning rod 7. After the embossed strip 4 and the smooth strip 5 are installed, the positioning rod 7 can be inserted into the circular holes at both ends. When installing the embossed strip 4 and the smooth strip 5, simply insert them into the elongated groove on the outside of the pressure roller 3 and the receiving roller 2. Then push the strip positioning ring 6 back towards both ends of the pressure roller 3 and the receiving roller 2 and rotate it 15°. At this time, the positioning rod 7 on the strip positioning ring 6 will be aligned with the circular holes at both ends of the embossed strip 4 and the smooth strip 5. Then the strip positioning ring 6 can be released. At this time, the magnetic plates at both ends of the receiving roller 2 and the pressure roller 3 will push the strip positioning ring 6 to slide towards the middle position of the receiving roller 2 and the pressure roller 3. Then the positioning rod 7 will be inserted into the circular holes at both ends of the embossed strip 4 and the smooth strip 5, thereby locking the position of the embossed strip 4 and the smooth strip 5.

[0035] Example 2, based on Example 1, such as Figures 1-6As shown, a layer of rubber can be pasted in the long strip groove on the outside of the receiving roller 2 and the pressure roller 3. A layer of rubber can also be wrapped on the outer side wall of the embossed strip 4 and the smooth strip 5 that contact the inner wall of the long strip groove. Therefore, when the embossed strip 4 and the smooth strip 5 are installed in the long strip groove on the outside of the receiving roller 2 and the pressure roller 3, these rubbers will be in close contact, so that the embossed strip 4 and the smooth strip 5 will not easily slip outward, making it easy to install all the embossed strip 4 and the smooth strip 5 at once.

[0036] The working principle of this embodiment is as follows: During installation, the main shaft of the external motor can be connected to the pressure roller 3 and the receiving roller 2. During embossing, the external motor can drive the pressure roller 3 and the receiving roller 2 to rotate synchronously in opposite directions under the support of the mounting base 1. Then, the card paper to be embossed can be directly pushed towards the pressure roller 3 and the receiving roller 2. During this process, the pressure roller 3 and the receiving roller 2 cooperate to clamp the card paper and drive it to move. Moreover, the embossing strip 4 on the receiving roller 2 and the embossing strip 4 on the pressure roller 3 work together to squeeze the card paper to achieve embossing. After the glossy strip 5 is installed at equal intervals, the spacing of the embossing strip 4 can be increased. During use, the glossy strip 5 can be selectively installed. If the required embossing is relatively dense, the glossy strip 5 does not need to be installed. If the required embossing is dense, the glossy strip 5 can be installed.

[0037] When it is necessary to disassemble and replace the embossed strip 4 and the smooth strip 5, first push the strip positioning ring 6 towards both ends of the receiving roller 2 and the pressure roller 3. At this time, the positioning rod 7 on one side of the strip positioning ring 6 will disengage from the round holes at both ends of the embossed strip 4 and the smooth strip 5. Therefore, the embossed strip 4 and the smooth strip 5 can be pried out of the elongated groove on the outside of the receiving roller 2 and the pressure roller 3 for disassembly. When reinstalling the embossed strip 4 and the smooth strip 5, first rotate the strip positioning ring 6 15° and then release it. Because the strip positioning ring 6 repels the magnetic plates at both ends of the receiving roller 2 and the pressure roller 3, the magnetic plates at both ends of the receiving roller 2 and the pressure roller 3 will push the strip positioning ring 6 to slide towards the middle position of the receiving roller 2 and the pressure roller 3. At the same time, the positioning rod 7 will be embedded in the round hole on one side of the annular groove at both ends of the receiving roller 2 and the pressure roller 3. Therefore, it will not affect the installation of embossed strip 4 and smooth strip 5. When installing embossed strip 4 and smooth strip 5, there is no need to continuously push the strip positioning ring 6. When installing embossed strip 4 and smooth strip 5, simply insert them into the long strip groove on the outside of pressure roller 3 and receiving roller 2. Then push the strip positioning ring 6 back towards both ends of pressure roller 3 and receiving roller 2 and rotate it 15°. At this time, the positioning rod 7 on the strip positioning ring 6 will be aligned with the round holes at both ends of embossed strip 4 and smooth strip 5. Then the strip positioning ring 6 can be released. At this time, the magnetic plates at both ends of receiving roller 2 and pressure roller 3 will push the strip positioning ring 6 to slide towards the middle position of receiving roller 2 and pressure roller 3. Then the positioning rod 7 will be embedded in the round holes at both ends of embossed strip 4 and smooth strip 5, thereby locking the position of embossed strip 4 and smooth strip 5.
