Description

Technical Field

[0001] This utility model belongs to the technical field of tissue paper embossing devices, and particularly relates to an airbag-controlled four-sided locking embossing device. Background Technology

[0002] In the household paper manufacturing industry, facial tissues, as a common hygiene product, directly impact the consumer experience with their quality and appearance. To enhance the texture, aesthetics, and absorbency of facial tissues, embossing is widely used in their production. By creating specific patterns or designs on the surface of the tissues, not only is the friction increased, making them easier to pull out, but the product also gains a unique visual appeal, improving its market competitiveness.

[0003] Currently, most existing tissue paper embossing devices on the market employ a horizontally arranged drive roller and embossing roller structure. In this traditional structure, the drive roller acts as the power output component, driving the embossing roller to rotate. The embossing roller then directly contacts the tissue paper, forming embossing patterns on the tissue paper surface through compression. However, this type of embossing device has revealed many problems in practical applications. From the perspective of the driving method, each embossing roller in existing embossing devices is typically driven by a separate cylinder to achieve the embossing action (the spring elastically presses against the embossing roller). While this design can achieve the embossing function to a certain extent, it has significant limitations.

[0004] On the one hand, because each embossing roller requires an independent cylinder and spring, the equipment structure is complex and has numerous parts, which not only increases the manufacturing cost of the equipment but also makes the installation, debugging, and maintenance of the equipment extremely cumbersome. During the production process, if a cylinder or spring malfunctions, the entire drive system needs to be inspected and repaired, which seriously affects production efficiency.

[0005] On the other hand, this independent driving method makes it difficult to guarantee the uniformity and consistency of pressure among the various embossing rollers. In the actual embossing process, due to factors such as manufacturing errors of the cylinder, fluctuations in air source pressure, and wear of the spring, the pressure applied to the tissue paper by different embossing rollers may vary. Excessive pressure from some embossing rollers can lead to overly deep embossing on the tissue paper surface, or even damage to the tissue paper, affecting product quality; while insufficient pressure from some embossing rollers will fail to form a clear and complete embossing pattern on the tissue paper surface, resulting in poor embossing effect and failing to meet consumers' requirements for product appearance.

[0006] Furthermore, existing embossing equipment presents numerous inconveniences when replacing and adjusting embossing rollers. Because the drive mechanisms of each embossing roller are independent, when different specifications or types of rollers need to be replaced to adapt to different embossing requirements, operators must disassemble and install the cylinders, springs, and rollers one by one—a cumbersome and time-consuming process. This not only increases production costs but also limits production flexibility, making it impossible to quickly respond to changes in market demand.

[0007] Therefore, the inventors dedicated themselves to designing an embossing device to solve the above problems. Utility Model Content

[0008] The purpose of this utility model is to provide an airbag-controlled four-sided locking embossing device with a simple structure, which reduces the manufacturing cost and maintenance difficulty of the equipment. At the same time, it produces uniform embossing, significantly improving the embossing effect and quality. Furthermore, it allows for quick replacement and adjustment of the embossing rollers, thereby improving production flexibility and efficiency.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] An airbag-controlled four-sided locking embossing device includes two spaced-apart side plates. At least one embossing assembly is disposed between the two side plates. The embossing assembly includes two crossbeams, two rows of transversely arranged embossing rollers, and a transversely arranged drive roller. The two crossbeams are transversely spaced and fixed between the two side plates. The two rows of embossing rollers are located between the two crossbeams and are both linked to the drive roller. The drive roller is sandwiched between the two rows of embossing rollers and its two ends are rotatably connected to the two side plates respectively. The two rows of embossing rollers are located directly below and directly above the drive roller, respectively. The embossing rollers in the same row are rotatably mounted on the same roller seat. The roller seat is connected to the corresponding crossbeam through an airbag, thereby realizing the control of the embossing action of the embossing rollers in the same row by the airbag.

[0011] As an improvement of the airbag-controlled four-sided locking embossing device of this utility model, the roller seat includes a long strip-shaped bladder cover and a row of roller frames. The row of roller frames is fixed to the side of the bladder cover near the active roller. The row of embossing rollers is rotatably arranged on the row of roller frames in a corresponding manner. The bladder cover is placed on the corresponding crossbeam and forms a cavity with the crossbeam. The airbag is located in the cavity.

[0012] As an improvement of the airbag control four-sided locking embossing device of this utility model, the crossbeam is provided with a long strip-shaped fixing groove on the side facing the active roller, and the airbag cover is located in the fixing groove and forms the cavity with the fixing groove.

[0013] As an improvement of the airbag-controlled four-sided locking embossing device of this utility model, the crossbeam includes a fixed beam and a beam cover. The two ends of the fixed beam are respectively fixedly connected to the two side plates. The beam cover is sleeved on the fixed beam, and the beam cover is open on the side facing the active roller to form the fixed groove.

[0014] As an improvement of the airbag-controlled four-sided locking embossing device of this utility model, two crossbeams of the same embossing component are symmetrically arranged and located directly above and below the active roller, respectively. An active gear is sleeved on the active roller, and a driven gear is sleeved on the embossing shaft of each row of embossing rollers. The active gear meshes with the driven gear.

[0015] As an improvement of the airbag control four-sided locking embossing device of this utility model, the number of embossing components is two, and the two embossing components are arranged longitudinally at intervals.

[0016] As an improvement of the airbag-controlled four-sided locking embossing device of this utility model, the outer wall of the active roller is covered with protrusions for pressing multiple paper strips, or the outer wall of the active roller is provided with grooves and the protruding parts cover the outer wall of the active roller.

[0017] As an improvement of the airbag-controlled four-sided locking embossing device of this utility model, the two rows of embossing rollers of the same embossing component are staggered, and two paper guide rollers and a brush roller are provided on the same side of the active roller, with the brush roller located between the two paper guide rollers.

[0018] As an improvement of the airbag-controlled four-sided locking embossing device of this utility model, an arc-shaped roller and a paper feeding roller are provided at intervals above the two side plates, and a felt roller is pressed against the top of the paper feeding roller.

[0019] As an improvement of the airbag-controlled four-sided locking embossing device of this utility model, the two side plates are vertically arranged on a footrest, and the bottom of the footrest is provided with a bottom hole for paper tape to pass through relative to the position of the embossing component.

[0020] Compared with existing technologies, the airbag-controlled four-sided locking embossing device of this utility model sets two rows of embossing rollers directly below and above the drive roller, respectively, so that the drive roller and the embossing roller are vertically distributed. The roller seats of the same row of embossing rollers are connected to the corresponding crossbeams through airbags. The embossing action of the same row of embossing rollers is centrally controlled by inflating and deflating the airbags. This design has a simple structure, fewer parts, and reduces the manufacturing cost and maintenance difficulty of the equipment. At the same time, the airbag drive method can ensure the pressure uniformity and consistency between the same row of embossing rollers, which significantly improves the embossing effect and quality. In addition, replacing and adjusting the embossing rollers is also more convenient and quick, improving the flexibility and efficiency of production, and better meeting the market demand for high-quality tissue paper.

[0038] The embodiments of this utility model are described in detail below with reference to the accompanying drawings. The drawings are for reference and illustration only and do not constitute a limitation on the scope of patent protection of this utility model.

[0039] Reference Figures 1 to 15 An airbag-controlled four-sided locking embossing device includes two spaced-apart side plates 4 and at least one embossing assembly. The embossing assembly is disposed between the two side plates 4. The embossing assembly includes two crossbeams 5, two rows of transversely arranged embossing rollers, and a transversely arranged drive roller 2. The two crossbeams 5 are transversely spaced and fixed between the two side plates 4. The two rows of embossing rollers are located between the two crossbeams 5 and are both linked to the drive roller 2. The drive roller 2 is sandwiched between the two rows of embossing rollers and its two ends are rotatably connected to the two side plates 4 respectively. The two rows of embossing rollers are located directly below and directly above the drive roller 2 respectively. The same row of embossing rollers is rotatably disposed on the same roller seat 62. The roller seat 62 is connected to the corresponding crossbeam 5 through an airbag 6, thereby realizing the control of the embossing action of the same row of embossing rollers by the airbag 6.

[0040] Reference Figure 1 and Figure 5 The two side plates 4 are spaced apart, and each side plate 4 is covered with a side cover 1. In this utility model, the X-axis direction is defined as the horizontal direction (i.e., left and right direction), the Y-axis direction is defined as the vertical direction (i.e., front and back direction), and the Z-axis direction is defined as the vertical direction (i.e., up and down direction). In this embodiment, two embossing components are preferred. The two embossing components are spaced apart vertically (i.e., front and back) and located between the two side plates 4. The structures of the two embossing components are basically the same.

[0041] Reference Figure 6 , Figure 7 and Figure 8Two crossbeams 5 of the same embossing assembly are arranged symmetrically with vertical spacing, and the two crossbeams 5 are located directly above and below the drive roller 2, respectively. The following description focuses on the structure of one of the embossing assemblies. Each crossbeam 5 of the same embossing assembly includes a fixed beam 51 and a beam cover 52. The fixed beam 51 is elongated and arranged transversely between the two side plates 4. The left and right ends of the fixed beam 51 are fixedly connected to the two side plates 4, respectively. The beam cover 52 is elongated and cylindrical and is fitted onto the fixed beam 51. In the same embossing assembly, each beam cover 52 is open on one side facing the drive roller 2 to form an elongated fixed groove 511. The airbag 6 is located in the fixed groove 511. The seat 62 is installed in the fixing groove 511 and connected to the airbag 6. Each roller seat 62 includes a long strip-shaped cover 61 and a row of roller frames 31. The cover 61 covers the corresponding crossbeam 5 and forms a cavity with the crossbeam 5. Specifically, the cover 61 is located in the fixing groove 511 and forms the cavity with the fixing groove 511. The airbag 6 is located in the cavity and is connected to the cover 61. A row of roller frames 31 is fixed in a row at intervals on the side of the cover 61 near the drive roller 2. Each roller frame 31 is U-shaped and its opening faces the side of the drive roller 2. A row of embossing rollers is rotatably mounted on a row of roller frames 31. In this embodiment, the two rows of embossing rollers of the same embossing assembly... Specifically, there is a row of upper embossing rollers 34 and a row of lower embossing rollers 3. The row of upper embossing rollers 34 is located directly above the corresponding active roller 2 and is rotatably connected to the row of upper roller frames 31 (the upper roller frames 31 with their openings facing downwards) through the same embossing shaft 32. The row of lower embossing rollers 3 is located directly below the corresponding active roller 2 and is rotatably connected to the row of lower roller frames 31 (the lower roller frames 31 with their openings facing upwards) through another embossing shaft 32. In the same embossing assembly, the row of upper embossing rollers 34 and the row of lower embossing rollers 3 are staggered so that the local structure of the square flower pattern can be distributed to different embossing rollers through step-by-step pressing, and finally the complete pattern is formed by superposition. Within the same embossing assembly, in order to achieve linkage between the upper embossing roller 34 and the lower embossing roller 3 and the drive roller 2, the drive roller 2 is cylindrical and a drive gear 21 is respectively sleeved at its left and right ends. Driven gears 33 are fixedly sleeved at the left and right ends of the upper embossing shaft 32. A row of upper embossing rollers 34 is located between the two upper driven gears 33. Driven gears 33 are also fixedly sleeved at the left and right ends of the lower embossing shaft 32. A row of lower embossing rollers 3 is located between the two lower driven gears 33. The two driven gears 33 on the left are meshed with the drive gear 21 on the left, and the two driven gears 33 on the right are also meshed with the drive gear 21 on the right.

[0042] Reference Figures 11 to 14 The outer wall of the active roller 2 of this invention is covered with protrusions 22 for pressing multiple paper strips 82 (e.g., ...). Figure 11 and Figure 12 As shown), or the outer wall of the drive roller 2 is provided with grooves 23 and the protruding part covers the outer wall of the drive roller 2 (as shown). Figure 13and Figure 14 (As shown), so that embossing is less labor-intensive, and the multi-layer paper tape 82 can be pressed more tightly.

[0043] Reference Figure 3 and Figure 5 Each active roller 2 has two guide rollers 7 and one brush roller 71 on the same side. The brush roller 71 is located between the two guide rollers 7 and presses against the corresponding active roller 2. Brush covers 711 are provided above and below the brush roller 71. The guide rollers 7 and brush roller 71 are both long columns and are laterally rotated between the two side plates 4. All the guide rollers 7 and brush roller 71 are located between the two embossing components.

[0044] Reference Figure 3 and Figure 5 An arc-shaped roller 74 and a paper feeding roller 73 are spaced apart above the two side plates 4. The arc-shaped roller 74 is arc-shaped. A felt roller 72 is pressed directly above the paper feeding roller 73. The felt roller 72 and the paper feeding roller 73 are located between the two embossing components. The arc-shaped roller 74, the felt roller 72 and the paper feeding roller 73 are all arranged laterally between the two side plates 4 and rotatably mounted on the brackets at the top of the two side plates 4.

[0045] Reference Figure 9 and Figure 10 In this utility model, two side plates 4 are vertically arranged on a footrest 8, and the bottom of the footrest 8 is provided with a bottom hole 81 through which the paper tape 82 passes, relative to the position of the two embossing components.

[0046] Reference Figures 1 to 15 The working principle of the airbag-controlled four-sided locking embossing device of this utility model is as follows:

[0047] The multi-layer paper strip 82 passes sequentially over the curved roller 74 and the feed roller 73, then splits into two thinner paper strips 82. One paper strip 82 passes sequentially over the upper front guide roller 7, the upper front drive roller 2, and the lower front guide roller 7, then exits through the bottom hole 81 at the bottom of the footrest 8. Simultaneously, the other paper strip 82 passes sequentially over the upper rear guide roller 7, the upper rear drive roller 2, and the lower rear guide roller 7, then exits through the bottom hole 81 at the bottom of the footrest 8 (e.g., ...). Figure 10 (As shown).

[0048] In the same embossing assembly, when the drive roller 2 rotates, the drive gears 21 at both ends of the drive roller 2 drive the driven gears 33 at both ends of the upper and lower rows of embossing rollers to rotate, which in turn drives the upper and lower embossing shafts 32 to rotate. The upper and lower rows of embossing rollers rotate synchronously with their respective embossing shafts 32. The airbag 6 inflates to control the corresponding row of embossing rollers to press against the drive roller 2 to emboss. During the paper feeding process, one row of embossing rollers first presses out the horizontal edge and center pattern of the pattern on the paper, and then the other row of embossing rollers immediately presses out the vertical edge of the pattern on the paper. Through the coordinated cooperation of the two rows of embossing rollers, the pressing of the entire pattern is finally completed (e.g., Figure 15 (As shown).

[0049] This utility model's airbag-controlled four-sided locking embossing device vertically distributes the same embossing components. The roller seats 62 of the same row of embossing rollers are connected to the corresponding crossbeams 5 via airbags 6. Centralized control of the embossing action of the same row of embossing rollers is achieved through the inflation and deflation of the airbags 6. This innovative design features a simple structure, fewer parts, and reduced manufacturing costs and maintenance difficulty. Simultaneously, the airbag 6 driving method ensures pressure uniformity and consistency among the same row of embossing rollers, significantly improving the embossing effect and quality. Furthermore, replacing and adjusting the embossing rollers becomes more convenient and faster, improving production flexibility and efficiency, and better meeting the market demand for high-quality tissue paper.

[0050] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of protection of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the patent application of the present utility model shall still fall within the scope of the present utility model.
