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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a wood grain paper embossing machine for double-sided gravure printing, including a housing assembly 1. Mounting plates 2 are provided on both sides of the top of the housing assembly 1. A first pattern roller 3 is provided between the two mounting plates 2 via a bearing. A first slot 4 is formed in the center of the interior of the two mounting plates 2. Sliding grooves 5 are formed on the inner walls of the two first slots 4. Synchronous electric push rods 6 are provided at the top of the two mounting plates 2. Mounting seats 7 are provided at the extended ends of the two synchronous electric push rods 6. A second pattern roller 8 is provided between the two mounting seats 7 via a bearing. Slider blocks 9 are provided on both sides of the two mounting seats 7. A secondary sprocket 10 is provided at one end of the first pattern roller 3 and the second pattern roller 8. Two guide sprockets 11 are provided on one side of the mounting plate 2 via a bearing. A second slot 12 is formed at the top of one side of the mounting plate 2. Two sliding rods 13 are provided at both ends inside the second slot 12. Springs 14 are sleeved on the bottom outer ends of the two sliding rods 13. A sliding seat 15 is provided at the top outer end of the two sliding rods 13. A guide sprocket 16 is provided on one side of the sliding seat 15 via a bearing.

[0022] In this embodiment, as Figure 1 As shown, the housing assembly 1 includes a base 101, a motor 102 is disposed at the top center of the base 101, and a main sprocket 103 is disposed on the output shaft of the motor 102.

[0023] In this embodiment, as Figure 1 As shown, the main sprocket 103, the secondary sprocket 10, the guide sprocket 16 and the guide sprocket 11 are connected by a chain; the first embossing roller 3 and the second embossing roller 8 are used to realize the simultaneous embossing of the wood grain paper on both sides, which greatly improves the working efficiency of the wood grain paper during embossing, thus meeting the requirements of the double-sided gravure wood grain paper embossing machine.

[0024] In this embodiment, as Figure 1 As shown, the slide groove 5 and the slider 9 are connected by a sliding connection; this increases the stability of the mounting base 7 during movement, thereby preventing the mounting base 7 from tilting during movement.

[0025] In this embodiment, as Figure 1 As shown, the synchronous electric push rod 6 and the mounting base 7 are symmetrical about the vertical center line of the base 101; this allows the height of the second flower roller 8 to be adjusted according to the user's needs, thereby adjusting the embossing pressure of the wood grain paper according to the user's needs, and thus greatly improving the convenience of the wood grain paper embossing machine during use.

[0026] In this embodiment, as Figure 1 As shown, the internal dimensions of the first slot 4 and the external dimensions of the mounting base 7 are consistent; this ensures that the movement of the mounting base 7 is unidirectional and prevents the mounting base 7 from shifting during movement.

[0027] In this embodiment, as Figure 1As shown, the slide bar 13 and the slide block 15 are connected by a sliding connection; this makes the slide block 15 move in a single direction, avoiding the slide block 15 from shifting during movement, thereby greatly improving the stability of the slide block 15 during movement.

[0028] The usage and advantages of this utility model: The working process of this wood grain paper embossing machine for double-sided gravure printing is as follows:

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the base 101 is first placed in the designated position, and then the motor 102 is started by the controller. At this time, the motor 102 drives the main sprocket 103 to rotate. The main sprocket 103 drives the secondary sprocket 10, guide sprocket 11 and guide sprocket 16 to rotate through the chain. At the same time, the secondary sprocket 10 drives the first pattern roller 3 and the second pattern roller 8 to rotate synchronously. Then, the wood grain paper to be embossed is placed between the first pattern roller 3 and the second pattern roller 8. The first pattern roller 3 and the second pattern roller 8 are used to realize the synchronous embossing of both sides of the wood grain paper, which greatly improves the working efficiency of the wood grain paper during embossing. When it is necessary to adjust the embossing pressure of the wood grain paper, the two synchronous electric push rods 6 are started by the controller.

[0030] At this time, the extended ends of the two synchronous electric push rods 6 drive the mounting base 7 to move downward with the cooperation of the slider 9 and the slide groove 5. At this time, the two mounting bases 7 drive the second pattern roller 8 to move downward synchronously, so that the second pattern roller 8 moves to the required position, realizing the height adjustment of the second pattern roller 8 according to the user's needs. This allows for adjustment of the embossing pressure of the wood grain paper according to the user's needs, thereby greatly improving the convenience of the wood grain paper embossing machine during use. While the synchronous electric push rods 6 drive the second pattern roller 8 downward through the mounting base 7, the chain drives the slide block 15 to move downward synchronously with the cooperation of the two slide rods 13 through the guide sprocket 16. At this time, the slide block 15 compresses the spring 14, thereby realizing the height adjustment of the second pattern roller 8 at will, solving the problem of limited height adjustment of the second pattern roller 8, and thus meeting the requirements of the double-sided gravure wood grain paper embossing machine.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
