[0032] Implementation case 1:

[0033] Reference Figures 1 to 5 , an embossing device for toilet paper production, comprising a support frame 1, with a discharging roller 3 and a reeling roller 4 respectively disposed at both ends of the support frame 1, a toilet paper 2 roll to be embossed is placed on the discharging roller 3, and the reeling roller 4 is used to collect the embossed toilet paper 2 and then roll it into a paper roll for easy disassembly and transportation. Two sets of limit assemblies are disposed between the discharging roller 3 and the reeling roller 4, and the two sets of limit assemblies are used to keep the toilet paper 2 horizontal to prevent the paper from tilting and thus destroying the shape of the toilet paper 2 during the embossing process. An embossing assembly is disposed in the middle position of the support frame 1, and the embossing assembly is located between the two sets of limit roller assemblies, and is the main part for embossing the toilet paper 2, and the embossing assembly includes a synchronous embossing component and an embossing connection component;

[0034] The synchronous embossing component comprises two rollers, which are arranged one above the other, the upper roller 7 is the upper roller, and the lower roller 8 is the lower roller. The central axes of the upper roller 7 and the lower roller 8 are located in the same vertical plane. There is a gap between the two rollers, and toilet paper passes through the gap.

[0035] The cylinder surface of the upper roller 7 is surrounded by three embossed tiles 701. The embossed tiles 701 are tile-shaped, with one side protruding and the other side concave. The protruding surface of the embossed tiles 701 is engraved with an embossing pattern. A roller shaft 702 is arranged at the center of the cylinder. The central axis of the roller shaft 702 coincides with the central axis of the cylinder. Three support frames 703 are arranged in an array around the central axis of the roller shaft 702 on the side wall of the roller shaft 702. The support frames 703 are fixedly connected to the side wall of the roller shaft 702. The top of each support frame 703 is fixedly connected to the roller shaft 702. There is a positioning plate 704, and the embossed tile 701 is detachably connected to the positioning plate 704. The outer surface of the positioning plate 704 is tile-shaped. When the embossed tile 701 is installed on the positioning plate 704, the concave surface of the embossed tile 701 will be completely in contact with the outer surface of the positioning plate 704, and the edge of the embossed tile 701 will be aligned with the edge of the positioning plate 704. A rubber clamp 705 is provided between two adjacent embossed tiles 701. The rubber clamp 705 is a long strip, and the front and back of the rubber clamp 705 are both curved surfaces. The curvature of the curved surface is the same as that of the embossed tile 701. The two sides of the rubber clamp 705 that are in contact with the tile are both provided with grooves, and the grooves run through the length direction of the rubber clamp. The edges of the embossed tile 701 and the positioning plate 704 are provided with convex edges that fit in the grooves of the rubber clamp 705. When the three embossed tiles 701 are installed on their respective positioning plates 704, the rubber clamp 705 will limit the two adjacent embossed tiles 701. When the rubber clamp 705 is removed, the embossed tile 701 can be removed from the positioning plate 704 is removed. If the toilet paper 2 is to be embossed on both sides, the shape and structure of the lower roller 8 are exactly the same as those of the upper roller 7. If the toilet paper 2 is to be embossed on one side, the lower roller 8 is a simple cylindrical roller and does not need to be split into three embossing tiles 701. There is no embossing pattern on the surface of the cylinder. It is used to support the bottom surface of the toilet paper 2 during embossing. Since the embossing tile 701 is detachably connected, it is convenient to replace the tile to change the embossing pattern. The embossing tile 701 is light in weight and is more labor-saving to replace.

[0036] The embossing connection assembly includes a guide block 9, which is connected to both ends of the roller 702 through a bearing. A guide groove is provided on the support frame 1. The guide block 9 is arranged in the guide groove and can slide along the depth direction of the guide groove. The guide block 9 is a cubic block, and a spring 10 is fixedly connected to the upper surface. The upper end of the spring 10 is fixedly connected to a fixing frame 11, and both ends of the fixing frame 11 are connected to the support frame 1. The spring 10 is in a compressed state between the fixing frame 11 and the guide block 9. When the synchronous embossing structure embosses the toilet paper 2, the spring 10 can provide a part of the pressure to enhance the embossing effect.

[0037] The two groups of limiting components include a front limiting group 5 and a rear limiting group 6. The front limiting group 5 is located between the unwinding roller and the embossing component, and the rear limiting group 6 is located between the unwinding roller and the embossing component. The two groups of limiting groups have the same structure. Taking the front limiting group 5 as an example, the front limiting group 5 includes two limiting rollers. The shapes of the two limiting rollers are exactly the same, both are cylinders. The central axes of the two limiting rollers are located in the same vertical plane. A gap is left between the two limiting rollers that is just enough for the toilet paper 2 to pass through. The gap between the two limiting rollers is on the same horizontal plane as the gap between the upper roller 7 and the lower roller 8. In this way, the toilet paper 2 will remain in a horizontal state during embossing, thereby avoiding the problem that the toilet paper 2 is uneven and wrinkles are easily formed during embossing.

[0038] The unwinding roller 3 is provided with a roll of toilet paper 2 to be embossed, and the unwinding roller 3 is movably connected to the support frame 1 through a bearing, and the reeling roller 4 is used to reroll the embossed toilet paper 2 into a roll, which is convenient for collection and transportation, and the reeling roller 4 is movably connected to the support frame 1 through a bearing, and a driving motor is also connected to one end of the roller shaft 702 of the reeling roller 4, which can drive the toilet paper 2 to move from the unwinding roller 3 to the reeling roller 4;

[0039] During operation, the drive motor is started, and the toilet paper 2 to be embossed comes out from the unwinding roller 3, and then passes through the gap between the two limit rollers of the front limit group 5, so that the toilet paper 2 reaches the horizontal plane to be embossed, and then enters the gap between the upper and lower rollers 8 for embossing. After the embossing is completed, it passes through the gap between the two limit rollers of the rear limit group 6. The rear limit group 6 and the front limit group 5 jointly limit the position so that the toilet paper 2 keeps the paper horizontal during the embossing process. After coming out from the rear limit roller group, the toilet paper 2 will be collected on the winding roller 4.

[0040] Implementation case 2:

[0041] Reference Figures 6 to 10 , the structure of the embossing assembly is improved, the embossing connection assembly includes a crossbeam 14 and a bottom bracket 15, the crossbeam 14 is a rectangular long plate, the two ends of the crossbeam 14 are connected to the top of the support frame, a hydraulic cylinder 16 is arranged under the crossbeam 14, the lower end of the hydraulic cylinder 16 is fixedly connected to the upper embossing plate 12, the bottom bracket 15 is a rectangular long plate, the two ends of the bottom bracket 15 are connected to the bottom of the support frame, a hydraulic cylinder 16 is arranged on the top of the bottom bracket 15, the hydraulic cylinder 16 on the bottom bracket 15 is mirror-distributed with the hydraulic cylinder 16 on the crossbeam 14, and the upper end of the hydraulic cylinder 16 on the bottom bracket 15 is fixedly connected to the lower embossing plate 13;

[0042] The upper embossed plate 12 and the lower embossed plate 13 have the same structure, but the two are arranged in mirror symmetry. The upper embossed plate 12 and the lower embossed plate 13 both include a shell 1201, which is a rectangular parallelepiped. A groove is provided on the bottom surface of the rectangular parallelepiped. A synchronous embossing member is installed in the groove. The groove includes a module groove, which is a rectangular parallelepiped groove. A gravity block groove is provided at the geometric center of the bottom surface of the module groove. The gravity block groove is also a rectangular parallelepiped groove, and its opening area is smaller than that of the module groove.

[0043] The synchronous embossing component includes an embossing module 1202, which is installed in the module slot. The front of the embossing module 1202 is provided with an embossing pattern, and the side opposite to the embossing pattern side is fixedly connected to a telescopic short rod 1203, and the other end of the telescopic short rod 1203 is connected to a gravity block 1204, and the gravity block 1204 is installed in the gravity block slot. At this time, the gravity block 1204 and the embossing module 1202 can move simultaneously along the length direction of the housing 1201;

[0044] In order to facilitate the movement of the embossing module 1202 and the gravity block 1204, an inclined slide bar 1205 is arranged in the gravity block groove, and the inclined slide bar 1205 is arranged to be inclined. At the same time, a small pulley is arranged on the gravity block 1204 and is located above the inclined slide bar 1205. The small pulley contacts and cooperates with the inclined slide bar 1205. At this time, the gravity block is in a horizontal state, and the two ends of the inclined slide bar 1205 extend through the shell 1201 to the outside of the shell 1201, and are detachably connected to the shell 1201. For example, the two ends of the inclined slide bar 1205 are provided with external threads, which are threadedly connected with nuts. When the embossing module 1202 needs to be replaced, the inclined slide bar 1205 is first removed, the original embossing module 1202 is taken out, and then a new embossing module 1202 is installed to complete the replacement;

[0045] In the initial state, the synchronous embossing component is located at one side of the housing. When the gravity block and the embossing module move horizontally at the same time, the distance between the gravity block and the embossing module changes, and the length of the telescopic short rod 1203 also changes. When the gravity block moves to the high end of the inclined sliding rod 1205, if the gravity block or the embossing module 1202 is not restricted at this time, the gravity block can slide back to the initial position under the influence of gravity, that is, the gravity block can slide toward the low end of the inclined sliding rod 1205 under the influence of gravity, thereby forming the reset of the synchronous embossing component.

[0046] When embossing the toilet paper 2, the hydraulic cylinder 16 drives the upper and lower embossing plates 13 to approach the toilet paper surface synchronously. When the embossing modules 1202 of the two embossing plates press onto the toilet paper surface, the toilet paper 2 does not need to stop. The embossing module 1202 will move from the toilet paper 2 paper entry side to the exit side driven by the toilet paper 2 and emboss the toilet paper 2. After the embossing is completed, the upper and lower embossing plates 1 are controlled by the hydraulic cylinder to move in a direction away from the toilet paper 2. Since the inclined slide bar 1205 is installed at an angle, during the process of moving away, the gravity block 1204 in the embossing plate will move toward the lower end of the slide bar under the action of gravity. Since the gravity block 1204 is provided with a pulley in contact with the slide bar, it will quickly slide to the lower end. At the same time, the distance between the embossing module 1202 and the gravity block 1204 will also be restored to the initial state, thus preparing for the next embossing.
