[0027] See attached document Figures 1 to 2 As shown, this application provides a tissue embossing device, including a base 1, a paper feeding roller 2, a paper receiving roller 3, an embossing roller assembly, a movable frame 11, and an embossing roller drive. The paper feeding roller 2, the paper receiving roller 3, the embossing roller assembly, and the movable frame 11 are all mounted on the base 1, and the embossing roller drive is mounted on the movable frame 11.

[0028] Specifically:

[0029] like Figure 1 and Figure 2 As shown, each end of the base 1 is provided with a set of wheel seats 8. The paper feeding roller 2 and the paper taking roller 3 are respectively mounted on the wheel seats 8 via bearing seats. The paper feeding roller 2 is used to feed paper towels, and the paper taking roller 3 is used to roll up the paper towels. To realize the paper towel feeding and taking down between the paper feeding roller 2 and the paper taking roller 3, the paper feeding roller 2 and the paper taking roller 3 are synchronously driven by a paper towel driving component. The paper towel driving component includes a first synchronous sprocket 22, a second synchronous sprocket 23, a synchronous chain belt 24, and a second drive motor 19. Conventionally, the first synchronous sprocket 22 is fixedly mounted on one end of the paper feeding roller 2, and the second synchronous sprocket 23 is fixedly mounted on one end of the paper taking roller 3. The first synchronous sprocket 22 and the second synchronous sprocket 23 are located on the same side and are connected to each other via synchronous sprocket transmission. The second drive motor 19 is located on the opposite side of the first synchronous sprocket 22 and the second synchronous sprocket 23 and is connected to either sprocket via a coupling. It is conceivable that by using the second drive motor 19 to drive the paper feed roller 2 and the paper take-up roller 3 to move synchronously through the synchronous transmission component, the linear speed of the paper feed roller 2 and the paper take-up roller 3 remains the same, and the paper towel is steadily conveyed, avoiding the paper towel from being pulled or loosened.

[0030] In the above, such as Figure 1 and Figure 2 As shown, the embossing roller assembly is positioned between the feed roller 2 and the take-up roller 3, specifically, as follows: Figure 3As shown, the embossing roller assembly includes a lower roller seat 7, an upper roller seat 6, an upper roller 4, and a lower roller 5. The upper roller 4 is mounted on the upper roller seat 6 via a shaft bearing, and the lower roller 5 is mounted on the lower roller seat 7 via a shaft bearing. The bottom of the lower roller seat 7 is welded to the machine base 1. A set of guide rods 9 are vertically arranged on the top of the lower roller seat 7. Springs 10 are fitted onto the guide rods 9. The upper roller seat 6 is provided with guide holes relative to the guide rods 9. The upper roller seat 6 is fitted onto the guide rods 9 through the guide holes to form a sliding connection with the lower roller seat 7. The top of the guide rods 9 is provided with an anti-detachment end to prevent the upper roller seat 6 from detaching from the guide rods 9. In its natural state, the springs 10 lift the upper roller seat 6. At this time, there is a sufficient gap between the upper roller seat 6 and the lower roller seat 7 to facilitate the paper towel passing between the upper roller 4 and the lower roller 5.

[0031] At the same time, such as Figure 3 As shown, a guide rail 12 is provided on one side of the embossing roller assembly. The direction of the guide rail 12 is the same as the axial direction of the upper roller 4 and the lower roller 5. The guide rail 12 is welded to the machine base 1. The movable frame 11 is slidably installed in the guide rail 12 and moves along the guide rail 12. An electric push rod 13 is provided at the end of the guide rail 12 away from the embossing roller assembly. The electric push rod 13 is fixedly installed on the machine base 1, and the output rod of the electric push rod 13 is fixedly connected to the movable frame 11. The electric push rod 13 drives the movable frame 11 to move back and forth along the guide rail 12, so that the movable frame 11 moves closer to and away from the embossing roller assembly. In this embodiment, the movable frame 11 includes a gantry frame body. An inclined platform 14 is integrally formed on the side of the gantry frame body facing the upper roller seat 6. The bottom surface of the inclined platform 14 gradually slopes downward from the side of the upper roller seat 6 to the side away from the upper roller seat 6, and the inclined platform 14 always remains in contact with the upper roller seat 6. As can be imagined, in its natural state, the highest point of the inclined platform 14 is in contact with the upper roller seat 6. At this time, the spring 10 is in its original length, the upper roller seat 6 and the lower roller seat 7 are separated, and the distance between the upper roller 4 and the lower roller 5 is at its maximum. This is conducive to passing the tissue paper through the upper roller 4 and the lower roller 5. When the electric push rod 13 pushes the movable frame 11 to move towards the embossing roller assembly, the inclined platform 14 gradually presses the upper roller seat 6 down, and the upper roller 4 moves closer to the lower roller 5. After the electric push rod 13 reaches its maximum stroke, it stops feeding. At this time, the distance between the upper roller 4 and the lower roller 5 is reduced to the working gap, the spring 10 is compressed to its minimum, and the coils of the spring 10 fit together without jumping, so that the tissue paper can be embossed. After the embossing is completed, the electric push rod 13 retracts and drives the movable frame 11 to move away from the embossing roller assembly. At this time, the pressure of the inclined platform 14 on the upper roller seat 6 gradually decreases, the spring 10 resets and lifts the upper roller 4, and the distance between the upper roller 4 and the lower roller 5 returns to its maximum.

[0032] In the above, in order to achieve the rotation of the upper roller 4 and the lower roller 5 for embossing, such as Figure 3As shown, the embossing roller driving member is arranged on the movable frame 11 and can be engaged with the upper roller 4 and the lower roller 5 after the movable frame 11 approaches the embossing roller assembly. Specifically, the embossing roller driving member comprises a first transmission shaft 15, a second transmission shaft 16 and a first driving motor 25. The first transmission shaft 15 is coaxially arranged corresponding to the upper roller 4, and the second transmission shaft 16 is coaxially arranged corresponding to the lower roller 5. Both the first transmission shaft 15 and the second transmission shaft 16 are installed on the gantry frame body through belt shaft bearings. A driven gear 18 is sleeved on the first transmission shaft 15, and a driving gear 17 is sleeved on the second transmission shaft 16. The driving gear 17 and the driven gear 18 are engaged, and the output end of the first driving motor 25 is drivingly connected with the second transmission shaft 16 through a shaft coupling. In order to realize the engagement of the first transmission shaft 15 with the upper roller 4 and the engagement of the second transmission shaft 16 with the lower roller 5, a cross pin 20 is arranged at one end of the first transmission shaft 15 and the second transmission shaft 16 close to the embossing roller assembly. The upper roller 4 and the lower roller 5 are provided with cross pin holes 21 facing one end of the first transmission shaft 15 and the second transmission shaft 16. When the movable frame approaches the upper roller 4 and the lower roller 5 with the first transmission shaft 15 and the second transmission shaft 16, the cross pin 20 is gradually inserted into the cross pin hole 21. In order to realize the insertion of the cross pin 20 into the cross pin hole 21, in this embodiment, the tail of one end of the inclined table 14 connected with the gantry frame body has a horizontal section. It can be imagined that when the movable frame 11 approaches the side of the embossing roller assembly to the horizontal section and the upper roller seat 6 is in contact, the cross pin 20 is just in contact with the cross pin hole 21. At this time, the upper roller seat 6 will not continue to move downward, and the electric push rod 13 has not reached the maximum stroke and continues to push the movable frame 11 to move. The cross pin 20 will be accurately inserted into the cross pin hole 21 until the electric push rod 13 reaches the maximum stroke and stops.

[0033] It can be found that in the natural state, the highest part of the inclined table 14 is in contact with the upper roller seat 6, at this time the spring 10 is in the original length state, the upper roller seat 6 and the lower roller seat 7 are kept apart, and the distance between the upper roller 4 and the lower roller 5 is the largest. At this time, it is beneficial to pass the paper towel between the upper roller 4 and the lower roller 5. When the electric push rod 13 pushes the movable frame 11 to move to the side of the embossing roller assembly, the inclined table 14 gradually presses the upper roller seat 6 downward, and the upper roller 4 approaches the lower roller 5. The electric push rod 13 stops feeding after reaching the maximum stroke. At this time, the distance between the upper roller 4 and the lower roller 5 is reduced to the working gap. When the movable frame 11 approaches the side of the embossing roller assembly, the cross pin 20 on one side of the first transmission shaft 15 and the second transmission shaft 16 is gradually inserted into the cross pin hole 21 on one side of the upper roller 4 and the lower roller 5 to complete the engagement. Through the rotation of the first driving motor 25, power is transmitted to the upper roller 4 and the lower roller 5 through the first transmission shaft 15 and the second transmission shaft 16 to realize the rotation and embossing of the upper roller 4 and the lower roller 5.

[0034] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
