Description

Technical Field

[0001] The utility model relates to the technical field of embossing rollers, in particular to a staggered rubber embossing roller for daily paper. Background Art

[0002] The embossing roller refers to a cylindrical rotatable object in the machine. The power source in the machine is often used to drive the embossing roller, which rolls on the surface of the paper towel material. The embossing roller generates pressure to process the paper towel material. As the core part of the paper towel embossing machine, the embossing roller can improve the water absorption performance of the paper towel, improve the surface beauty of the paper towel product, strengthen anti-counterfeiting and protect the trademark by pressing different embossing shapes.

[0003] Currently, conventional paper towel embossing rollers on the market are shown in the patent document with patent number CN202223061450.0 and the name "An embossing mechanism of paper towel processing equipment". It includes an embossing component. A group of embossing components includes a smooth roller and at least two pattern rollers. When embossing the pattern, one of the pattern rollers is pressed with the smooth roller, and the other pattern rollers are separated from the smooth roller.

[0004] This type of embossing equipment requires a patterned roller with a concave-convex pattern and a smooth roller to fit together, so that the paper towel passing through the gap between the patterned roller and the smooth roller is pressed to print the concave-convex pattern on the patterned roller to complete the paper towel embossing process. However, the patterned roller and the smooth roller of this type of embossing equipment are generally made of metal and are in direct hard contact. After running for a period of time, the concave-convex pattern on the patterned roller is easy to wear and make abnormal noises, and the service life is short, requiring frequent maintenance and repairs. In addition, it often takes more than one pressing process of the patterned roller and the smooth roller to form a stable printing texture on the surface of the paper towel, and the processing efficiency is low. Utility Model Content

[0005] In order to solve the problems that the pattern roller and smooth roller that fit each other in the general paper towel embossing roller shaft assembly on the market are easily worn due to hard contact, have a short service life and often need maintenance or even replacement, have low processing efficiency, cannot adapt to high-intensity production capacity requirements, and the quality stability of processing embossing cannot be guaranteed, we provide a staggered rubber embossing roller for household paper.

[0006] The staggered rubber embossing roller for daily life paper is characterized in that it comprises a first roller shaft and a second roller shaft, the outer sides of the first roller shaft and the second roller shaft are fixedly sleeved with a rubber sleeve, the outer surface of the rubber sleeve is provided with a concave-convex engraving layer, and the concave-convex engraving layers of the first roller shaft and the second roller shaft are meshed with each other.

[0007] Furthermore, the length of the rubber sleeve is smaller than the first roller shaft and the second roller shaft, and the rubber sleeve is fixed to the middle of the first roller shaft and the second roller shaft.

[0008] Furthermore, both ends of the first roller shaft and the second roller shaft are coaxially connected in series with rotary bearings.

[0009] Furthermore, both ends of the first roller shaft and the second roller shaft are provided with supporting side plates, and vertical sliding grooves are opened on the supporting side plates. A sliding block and a fixed block are sleeved in the vertical sliding groove from top to bottom, and the rotating bearings at both ends of the first roller shaft are installed in the sliding block, and the rotating bearings at both ends of the second roller shaft are installed in the fixed block.

[0010] Furthermore, a vertical nut is fixedly connected to the outer side of the sliding block, a lifting screw is threadedly sleeved on the vertical nut, a rotating seat is arranged on the outer side of the supporting side plate, and the lifting screw is rotatably connected to the rotating seat.

[0011] Furthermore, a paper pressing gap is provided between the concave-convex engraved layers of the first roller and the second roller.

[0012] Furthermore, the raised edges of the concave-convex engraving layer are all provided with arc chamfers.

[0013] The advantages of the utility model are:

[0014] 1. The two pressed rollers are made of soft rubber material to avoid collision and wear, effectively improving the service life of the equipment.

[0015] 2. The concave and convex engraved layers of the two rollers mesh with each other, effectively preventing mutual collision. Compared with the structure with one concave and convex layer on one side and one smooth layer on the other side, it has a stronger pressing deformation effect, so that the embossing of paper towels can be completed in one time.

[0016] 3. The concave and convex engraving layer on the outside of the rubber sleeve is easy to make, and the embossed pattern can be quickly replaced.

[0017] 4. The distance between the first roller and the second roller is adjustable, which is convenient for adjusting the depth of embossing and can avoid the first roller and the second roller being too close to each other, which may cause excessive pressing force and cause paper perforation during embossing.

[0028] like Figure 1-3 As shown, this embodiment provides a staggered rubber embossing roller for daily life paper, characterized in that it includes a first roller shaft 1 and a second roller shaft 2, the outer sides of the first roller shaft 1 and the second roller shaft 2 are fixedly sleeved with a rubber sleeve 3, the outer surface of the rubber sleeve 3 is provided with a concave-convex engraving layer 4, and the concave-convex engraving layers 4 of the first roller shaft 1 and the second roller shaft 2 are meshed with each other.

[0029] The outer sides of the first roller 1 and the second roller 2 are both made of soft rubber, which can avoid hard contact wear and effectively increase the service life of the equipment. The concave and convex engraved layers 4 of the two rollers mesh with each other, which further avoids the collision between the concave and convex embossed textures, and has a stronger pressing deformation effect than the structure with one concave and convex layer on one side and one smooth layer on the other side, so that the embossing of the paper towel can be completed at one time.

[0030] In addition, the concave-convex engraving layer 4 on the outer side of the rubber sleeve 3 is easy to manufacture. For example, it can be engraved on the rubber sleeve 3 using a laser engraving machine on the market, which facilitates the rapid replacement of the embossing pattern according to production needs.

[0031] The length of the rubber sleeve 3 is smaller than the first roller 1 and the second roller 2, and the rubber sleeve 3 is fixed to the middle of the first roller 1 and the second roller 2. The rubber sleeve 3 with a smaller length and a thickness protruding from the first roller 1 and the second roller 2 facilitates the matching and alignment, and avoids the inaccurate positioning of the concave-convex engraved layer 4 on the first roller 1 and the second roller 2, resulting in failure to mesh.

[0032] Both ends of the first roller shaft 1 and the second roller shaft 2 are coaxially connected in series with a rotary bearing 5. The rotary bearing 5 can ensure the smoothness of the operation of the first roller shaft 1 and the second roller shaft 2.

[0033] Both ends of the first roller 1 and the second roller 2 are provided with supporting side plates 6, and the supporting side plates 6 are provided with vertical slide grooves 7, and the vertical slide grooves 7 are sleeved with sliding blocks 8 and fixed blocks 9 from top to bottom, and the rotating bearings 5 ​​at both ends of the first roller 1 are installed in the sliding blocks 8, and the rotating bearings 5 ​​at both ends of the second roller 2 are installed in the fixed blocks 9. The spacing between the first roller 1 and the second roller 2 can be adjusted by lifting and lowering the sliding block 8 in the vertical slide groove 7, which is convenient for users to adjust the depth of embossing.

[0034] A vertical nut 10 is fixedly connected to the outer side of the sliding block 8, and a lifting screw 11 is threadedly sleeved on the vertical nut 10. A rotating seat 12 is arranged on the outer side of the supporting side plate 6, and the lifting screw 11 is rotatably connected to the rotating seat 12. By rotating the lifting screw 11, the vertical nut 10 can be driven to position and lift, so as to more accurately adjust the distance between the first roller 1 and the second roller 2.

[0035] A paper pressing gap 13 is provided between the concave-convex engraved layer 4 of the first roller 1 and the second roller 2. In order to facilitate the paper to pass through between the first roller 1 and the second roller 2 and avoid excessive force on the paper during pressing and causing perforation, a certain gap can be provided to avoid excessive pressing force.

[0036] The raised edges of the concave-convex engraving layer 4 are all provided with arc chamfers. The arc chamfer design can avoid scratching the paper at the sharp corners and improve the smoothness of the rotational engagement and separation between the concave-convex engraving layer 4 on the first roller 1 and the second roller 2.

[0037] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementation modes. 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.
