Description

Technical Field

[0001] The utility model relates to the technical field of embossing rollers, in particular to a dynamic compensation three-roller embossing mechanism. Background Art

[0002] The embossing roller refers to a cylindrical rotatable object in a machine. The embossing roller is usually driven by a power source in the machine to roll on the surface of the tissue material. The embossing roller generates pressure to process the tissue material. As the core part of the tissue embossing machine, the embossing roller can improve the water absorption performance of the tissue, enhance the surface beauty of the tissue product, strengthen anti-counterfeiting, and protect trademarks by pressing different embossing shapes.

[0003] If multiple layers of paper are squeezed between the pattern roller and the smooth roller at the same time, fatigue will occur in the middle of the material after long-term operation. In order to ensure that the left, middle and right forces of the product are evenly embossed, the industry often alleviates this problem by increasing the diameter and thickness of the roller. The impact is increased power consumption, high-speed bouncing, uneven embossing, and rapid wear of the roller.

[0004] To ensure consistent and stable embossing of multi-layer paper, a new embossing roller design, such as that described in patent document CN92202542.8, titled "Embossing Device for Metal Foil Composite Paper," has emerged. This three-roller design employs a rubber roller on each side of the embossing roller. The symmetrical pressure prevents deflection. The composite paper strip is also rolled twice, with the upper and lower rubber rollers, significantly enhancing the clarity of the embossing.

[0005] However, although the above scheme mentions that the distance and pressing force between the rubber roller and the embossing roller can be adjusted by operating the rocker of the movable support, it lacks a specific design scheme for the adjustment mechanism, which is inconvenient to use. It cannot guarantee that it can be quickly adjusted when production specifications need to be adjusted and maintenance is required. It is easy for production to be suspended for a long time due to equipment debugging, which has a negative impact on the company's production efficiency. Utility Model Content

[0008] Furthermore, the rubber roller is connected in series to the rotating shaft, both ends of the rotating shaft are sleeved in the support arm, one end of the support arm is hinged to the roller bracket, and the other end is hinged to the output end of the telescopic cylinder.

[0029] In order to solve the problems that the existing three-roller embossing mechanism lacks a mechanism that can be adjusted efficiently and stably, cannot ensure the long-term efficient operation of the equipment, easily consumes a lot of time during equipment maintenance and debugging, and has a negative impact on the company's production efficiency, a dynamic compensation three-roller embossing mechanism is provided.

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

Thus, a feature defined as "first," "second," and the like may explicitly or implicitly include one or more of such features. In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be interpreted broadly.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0033] like Figure 1-6 As shown, this embodiment provides a dynamic compensation three-roller embossing mechanism, including a roller support 1, in which a pattern roller 2 with an embossed layer 201 on its surface is horizontally mounted. A rubber roller 4 and a smooth roller 3 are mounted on both sides of the pattern roller 2. Both ends of the rubber roller 4 are connected to a sliding seat 5, which is sleeved in a slide groove 6. The sliding seat 5 is driven by a telescopic cylinder. The pattern roller 2 is driven by a rotary servo 8. The rotary servo 8 and the telescopic cylinder are both electrically connected to an industrial control module 10. The telescopic cylinder includes a hydraulic telescopic rod 7 and a servo hydraulic station 701. The hydraulic telescopic rod 7 is connected to the servo hydraulic station 701 through a pipeline, and the servo hydraulic station 701 is electrically connected to the industrial control module 10.

[0034] In actual use, the rotary servo 8 can adopt a servo motor commonly used on the market, and the industrial control module 10 can also use an industrial computer commonly used on the market, so as to adjust the hydraulic pressure output by the servo hydraulic station 701 according to the rotation speed of the servo motor, thereby adjusting the lifting and lowering of the hydraulic telescopic rod 7, so as to achieve the effect that the faster the flower roller 2 rotates, the tighter the rubber roller 4 is pressed, thereby avoiding high-speed bouncing of the flower roller 2, uneven embossing, roller wear and other undesirable phenomena.

[0035] This embodiment can realize two embossing functions:

[0036] Function 1. The paper is squeezed between the rubber roller 4 and the pattern roller 2, and then squeezed between the pattern roller 2 and the smooth roller 3, which increases the depth of the paper pattern, increases the softness and toughness, and makes the paper more visually prominent.

[0037] Function 2: Multiple layers of paper are squeezed simultaneously between the pattern roller 2 and the smooth roller 3. The rubber roller 4, located at the opposite end of the smooth roller 3, provides a compressive force to the pattern roller 2 that varies with its rotational speed. Since the center of the material will fatigue over time, the industry often addresses this issue by increasing the roller diameter and thickness to ensure uniform embossing from left to right. However, this results in increased power consumption, high-speed bouncing, uneven embossing, and excessive roller wear. This embodiment perfectly solves these problems, increasing operating speed and reducing wear without increasing the steel roller diameter or power. This contributes to improved product quality and production efficiency.

[0038] The rubber roller 4 is connected in series to the rotating shaft 11. Both ends of the rotating shaft 11 are sleeved in support arms 401. One end of the support arm 401 is hinged to the roller bracket 1, and the other end is hinged to the output end of the telescopic cylinder. The support arm 401 provides support for the rubber roller 4, preventing the rubber roller 4 from relying solely on the telescopic cylinder for lifting and lowering, which would cause excessive load on the telescopic cylinder.

[0039] A telescopic pad 12 is positioned below and outside the end of the support arm 401 connected to the hydraulic telescopic rod 7. The top of the telescopic pad 12 is provided with a first inclined surface 13 sloping from the inside outward. A second inclined surface 14 is positioned above the bottom of the support arm 401, corresponding to the first inclined surface 13. The inclined telescopic pad 12, in conjunction with the support arm 401 mechanism, ensures that the rubber roller 4 remains in a stable position during lifting and lowering adjustments, preventing it from shaking, thereby improving the operational stability of the equipment.

[0040] The telescopic pad 12 is threadedly connected to a rotating screw 15, and the rotating screw 15 is electrically connected to the industrial control module 10. The telescopic pad 12 is generally adjusted in conjunction with the industrial control module 10 to ensure that the dynamic compensation effect is rapid and effective.

[0041] The first inclined surface 13 is tilted upward from the inside to the outside. Since the top outer side of the telescopic pad 12 is higher, the front end of the support arm 401 can be supported to prevent the rubber roller 4 from shaking back and forth.

[0042] A support base 101 is provided below the telescopic pad 12, and the support base 101 is detachably connected to the roller support 1. The support base 101 can provide support for the telescopic pad 12, thereby improving the lifting and positioning stability of the rubber roller 4.

[0043] The roller bracket 1 is symmetrically provided with slide grooves 6 on both sides. The slide grooves 6 are vertical to the ground. The left and right ends of the rubber roller 4, the pattern roller 2 and the smooth roller 3 are sleeved in the slide grooves 6 from top to bottom. The uniformly installed rollers are accurately aligned and easy to install and disassemble. The spacing between the rollers can be quickly adjusted according to production requirements.

[0044] The rubber roller 4, pattern roller 2, and smooth roller 5 are each connected to a rotary servo 8 via a reducer 9. These rotary servos 8 are electrically connected to an industrial control module 10. Under unified control by the industrial control module 10, the rollers operate smoothly and synchronously, facilitating monitoring and management. The reducer 9 reduces the operating load of the rotary servo 8, improving the smoothness of the equipment's operation.

[0045] The above content is a further detailed description of the present invention in combination with specific preferred implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
