Description

Technical Field

[0001] This utility model relates to the field of tissue paper embossing technology, and in particular to a tissue paper embossing device. Background Technology

[0002] In the tissue paper manufacturing industry, embossing is a crucial step in enhancing product quality and competitiveness. By pressing pre-designed shapes onto the surface of tissue paper, it not only endows the paper paper with unique aesthetic patterns, satisfying consumers' diverse demands for product appearance, but also, through the pressing of specific areas during the embossing process, firmly bonds multiple layers of tissue paper (such as two-, three-, or four-layer paper paper) together, effectively preventing problems such as loosening or delamination during storage, transportation, and use, thus ensuring the structural integrity of the product.

[0003] Because different tissue products have significant differences in the number of layers and the thickness of each layer, in order to ensure that the embossing effect meets the design requirements, the relevant parameters of the embossing machine need to be adjusted according to the actual thickness of the tissue and the required embossing depth before the embossing operation. One of the key adjustment items is the distance between the two embossing rollers. For this reason, various embossing machines with adjustable embossing roller spacing have emerged in the industry.

[0004] For example, Chinese utility model patent CN221809648U, entitled "An Embossing Depth Adjustment Mechanism for a Tissue Embossing Machine," discloses a technical solution capable of adjusting the distance between the upper and lower embossing rollers. In this solution, after adjusting the roller spacing, to ensure the tension of the drive belt and maintain stable operation of the embossing machine, the belt needs to be re-tensioned using two pressure rollers. Specifically, in this structure, the two pressure rollers used to adjust belt tension are fed through two cam structures. While this design, using cams on both sides for synchronous feeding, theoretically achieves synchronous adjustment of the two pressure rollers, ensuring symmetrical force distribution and thus guaranteeing the embossing accuracy of the rollers, in practical applications, the extremely high requirements for the synchronization control of the cams on both sides make the structure difficult to debug, hindering efficient operation and maintenance during production, and necessitating improvement. Utility Model Content

[0005] The purpose of this invention is to provide a tissue embossing device in response to the defects and deficiencies of the existing technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] The paper towel embossing device of this utility model includes a fixed frame, a lower embossing roller rotatably connected to the fixed frame, an upper embossing roller slidably connected to the fixed frame, a steel cable, and a lifting adjustment component connected to the fixed frame; the fixed frame is provided with a lifting adjustment component for driving the upper embossing roller to move up and down.

[0008] The fixed frame is equipped with a power component for driving the lower embossing roller to rotate;

[0009] Both the upper and lower embossing rollers are fixed with synchronous pulleys; a synchronous belt is tensioned between the two synchronous pulleys.

[0010] Both sides of the synchronous belt are provided with horizontal sliding seats that are slidably connected to the fixed frame; rollers and pressure rollers are rotatably connected to both sides of the horizontal sliding seats; the pressure rollers on both sides press against both sides of the synchronous belt; the two ends of the steel cable are fixed to the lifting adjustment assembly; the lifting adjustment assembly is set on the axis of symmetry of the two rollers; the steel cable is looped around the wheel body of the two rollers.

[0011] Furthermore, the lifting adjustment assembly includes a lifting frame, a lifting guide sleeve fixed on the fixed frame, a lifting guide column fixed on the lifting frame, and a lifting adjustment screw rotatably connected to the fixed frame; an internal threaded sleeve that is threadedly connected to the lifting frame is fixed on the lifting frame; the lifting guide column is slidably connected to the lifting guide sleeve; and both ends of the upper embossing roller are rotatably connected to the lifting frame.

[0012] Furthermore, the roller is a grooved roller.

[0013] Furthermore, the lifting adjustment assembly includes a clamping adjustment bolt, a connecting block, and a clamping adjustment nut; the clamping adjustment nut is fixed on the fixing frame; the clamping adjustment bolt is threaded onto the clamping adjustment nut; both ends of the steel cable are fixed on the connecting block; the clamping adjustment bolt is rotatably connected to the connecting block.

[0014] Furthermore, a fixing plate is fixed on the fixing frame; the clamping adjusting nut is fixed on the fixing plate; and the connecting block is slidably connected to the fixing plate.

[0015] Furthermore, each of the horizontal sliding seats is fixed with a horizontal slider; and the fixed frame is fixed with a horizontal straight guide rail that is slidably connected to the horizontal slider.

[0016] The advantages of this invention with the above structure are as follows: Since the tension adjustment component is set on the axis of symmetry of the two rollers, after the steel cable is tightened by the tension adjustment component, the inner surface of the steel cable is pressed against the wheel body of the roller. When the pressure rollers on both sides are pressed against the surface of the synchronous belt, the steel cable forms an isosceles triangle, making the pressure of the steel cable on the rollers consistent; ensuring that the pressure rollers exert consistent pressure on both sides of the synchronous belt; and ensuring consistent pressure on both sides of the synchronous belt through the flexible self-adaptation of the steel cable itself. On the basis of ensuring consistent pressure on both sides of the synchronous belt, the adjustment difficulty of the tightening device is reduced, and the length of the steel cable is easy to cut and control, which facilitates maintenance and reduces costs.

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] like Figures 1 to 5 As shown, the paper towel embossing device of this utility model includes a fixed frame 1, a lower embossing roller 11 rotatably connected to the fixed frame 1, an upper embossing roller 13 slidably connected to the fixed frame 1, a steel cable 6, and a lifting adjustment component connected to the lifting adjustment assembly; the fixed frame 1 is provided with a lifting adjustment assembly for driving the upper embossing roller 13 to perform lifting and lowering movements.

[0030] The fixed frame 1 is equipped with a power assembly for driving the lower embossing roller 11 to rotate;

[0031] Both the upper embossing roller 13 and the lower embossing roller 11 are fixed with synchronous pulleys 8; a synchronous belt 9 is tensioned between the two synchronous pulleys 8.

[0032] Both sides of the synchronous belt 9 are provided with horizontal sliding seats 19 that are slidably connected to the fixed frame 1; rollers 7 and pressure rollers 17 are rotatably connected to both sides of the horizontal sliding seats 19 respectively; the pressure rollers 17 on both sides are pressed against both sides of the synchronous belt 9; the two ends of the steel cable 6 are fixed to the lifting adjustment assembly; the lifting adjustment assembly is set on the axis of symmetry of the two rollers 7; the steel cable 6 is sleeved on the wheel body of the two rollers 7;

[0033] The power unit is used to drive the lower embossing roller 11 to rotate, while the upper embossing roller 13 achieves synchronous movement through two synchronous pulleys 8 and a synchronous belt 9; the power unit consists of a motor 10 and a reduction gearbox 12; the motor 10 drives the lower embossing roller 11 to rotate through the reduction gearbox 12;

[0034] The lifting and adjusting component drives the upper embossing roller 13 to move up and down, thereby adjusting the gap between the upper embossing roller 13 and the lower embossing roller 11.

[0035] Because the tension adjustment assembly is set on the axis of symmetry of the two rollers 7, after the steel cable 6 is tightened by the tension adjustment assembly, the inner surface of the steel cable 6 presses against the wheel body of the roller 7. When the pressure rollers 17 on both sides press against the surface of the synchronous belt 9, the steel cable 6 forms an isosceles triangle, making the pressure of the steel cable 6 on the rollers 7 consistent. This ensures that the pressure rollers 17 exert consistent pressure on both sides of the synchronous belt 9. Through the flexible self-adaptation of the steel cable 6, the pressure on the synchronous belt 9 is consistent. On the basis of ensuring consistent pressure on both sides of the synchronous belt 9, the debugging difficulty of the tightening device is reduced, and the steel cable 6 is easy to maintain and has a lower cost.

[0036] In a preferred embodiment of this utility model, the lifting adjustment assembly includes a lifting frame 14, a lifting guide sleeve 15 fixed on a fixed frame 1, a lifting guide column 1401 fixed on the lifting frame 14, and a lifting adjustment screw 16 rotatably connected to the fixed frame 1; an internally threaded sleeve 1402 threadedly connected to the lifting frame 14 is fixed on the lifting frame 14; the lifting guide column 1401 is slidably connected to the lifting guide sleeve 15; both ends of the upper embossing roller 13 are rotatably connected to the lifting frame 14;

[0037] The internal threaded sleeve 1402 is a sleeve with internal threads. By rotating the lifting adjustment screw 16, the internal threaded sleeve 1402 is driven to move up and down along the length of the lifting guide sleeve 15, thereby realizing the lifting of the lifting frame 14, accurately adjusting the height position of the upper embossing roller 13, and ensuring that the embossing effect is uniform.

[0038] In a preferred embodiment of this utility model, the roller 7 is a grooved roller; the grooved roller can be either a V-groove roller or a U-groove roller; the V-groove roller structure can prevent the steel cable 6 from slipping off the roller 7 and can ensure the stability of the connection between the roller 7 and the steel cable 6.

[0039] In a preferred embodiment of this utility model, the lifting adjustment assembly includes a clamping adjustment bolt 2, a connecting block 5, and a clamping adjustment nut 4; the clamping adjustment nut 4 is fixed on the fixing frame 1; the clamping adjustment bolt 2 is threadedly connected to the clamping adjustment nut 4; both ends of the steel cable 6 are fixed on the connecting block 5; the clamping adjustment bolt 2 and the connecting block 5 are rotatably connected.

[0040] The two connection points of the steel cable 6 and the connecting block 5 are symmetrically arranged on the axes of symmetry of the two rollers 7. The two connection points of the steel cable 6 and the connecting block 5 can also coincide on the axes of symmetry of the rollers 7, which can ensure that the steel cable 6 forms an isosceles trapezoid or an isosceles triangle after being tightened. After the clamping adjusting nut 4 is rotated, the clamping adjusting bolt 2 can drive the connecting block 5 to move up and down along the length of the axes of symmetry of the two rollers 7, so that the steel cable 6 is loosened or tightened on the rollers 7.

[0041] In a preferred embodiment of this utility model, a fixing plate 3 is fixed on the fixing frame 1; the clamping adjusting nut 4 is fixed on the fixing plate 3; and the connecting block 5 is slidably connected to the fixing plate 3.

[0042] A straight groove is opened on the fixed plate 3 to slide and connect with the connecting block 5, which is used as a guide for the sliding of the connecting block 5; the entire lifting and adjusting assembly is integrated into the fixed plate 3.

[0043] In a preferred embodiment of this utility model, each of the horizontal sliding seats 19 is fixed with a horizontal slider 20; the fixed frame 1 is fixed with a horizontal straight guide rail 18 that is slidably connected to the horizontal slider 20; the horizontal sliding seats 19 and the fixed frame 1 are slidably connected through the horizontal slider 20 and the horizontal straight guide rail 18.

[0044] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
