[0036] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0037] like Figures 1-9 The illustrated printing device for producing cellulose sponge fabric includes a base plate 1. A connecting seat 3 is movably mounted on the upper surface of the base plate 1 via an adjustment mechanism. A rotating shaft 4 is rotatably mounted on the front surface of the connecting seat 3 via a servo mechanism. A concave frame 5 is fixedly fitted on the outer surface of the rotating shaft 4. A printing roller 9 is rotatably mounted on the front surface of the concave frame 5 via a drive mechanism. A wetting box 10 is mounted on the upper surface of the base plate 1 via a lifting mechanism. The wetting box 10 is located below the printing roller 9. A contact plate 16 is movably mounted on the upper edge of the wetting box 10 via several elastic mechanisms. A strip-shaped opening 17 is opened through the outer surface of the contact plate 16. A lower guide plate 18 is fixedly connected to one end of the strip-shaped opening 17 near the printing roller 9, and an upper guide plate 19 is fixedly connected to the other end of the strip-shaped opening 17. A soft strip 20 is embedded in the upper surface of the contact plate 16. When the printing roller 9 rotates around the rotating shaft 4, it pushes the upper edge of the soft strip 20.

[0038] like Figure 3As shown, the adjustment mechanism includes a movable plate 2 that is slidably mounted on the upper surface of the base plate 1 in a front-to-back direction. A first lead screw 34 with a threaded engagement is threaded through the lower end of the front surface of the movable plate 2. Fixed plates 35 are rotatably sleeved at the front and rear ends of the outer surface of the first lead screw 34, respectively. The fixed plates 35 are fixedly connected to the edge of the base plate 1. The front surface of the movable plate 2 is vertically slidably engaged with the connecting seat 3 via the lead screw mechanism. The lead screw mechanism includes a second lead screw 36 rotatably mounted on the inner side of the movable plate 2. A vertical slide seat 37 with a threaded engagement is sleeved on the outer surface of the second lead screw 36. The vertical slide seat 37 is slidably engaged with the movable plate 2. The front end of the vertical slide seat 37 is fixedly connected to the rear surface of the connecting seat 3. Rotating heads 38 are fixedly connected to the front end of the first lead screw 34 and the upper end of the second lead screw 36, respectively. The rotating head 38 allows the user to rotate the first lead screw 34 or the second lead screw 36. When the first lead screw 34 rotates, the movable plate 2 moves back and forth. When the second lead screw 36 rotates, the vertical slide 37 slides vertically, causing the connecting seat 3 to move up and down. This design allows the printing roller 9 to move back and forth and up and down. When used on the side of the conveyor belt, the printing roller 9 can be adjusted to be above the conveyor belt.

[0039] The servo mechanism includes a first motor 39 fixedly mounted on the front surface of the connector 3, and the output shaft of the first motor 39 is fixedly connected to the rear end of the rotating shaft 4. The first motor 39 is a servo motor with a brake to precisely control the rotation angle of the rotating shaft 4.

[0040] like Figure 2 , Figure 6 As shown, the drive mechanism includes a second motor 6 fixedly mounted on the rear surface of the concave frame 5. The output shaft of the second motor 6 is fixedly connected to a mounting plate 7. At least two mounting bolts 8 are provided through the rear surface of the mounting plate 7. The front end of the mounting bolt 8 is embedded in the rear surface of the printing roller 9 and is threadedly engaged. After unscrewing the mounting bolts 8, the user can disassemble and replace the printing roller 9, which is convenient to use.

[0041] like Figure 2 , Figure 3 , Figure 7 As shown, the lifting mechanism includes a base 31 set on the upper surface of the base plate 1. Side grooves 33 are respectively opened on the front and rear surfaces of the base plate 1. L-shaped plates 32 are fixedly connected to the front and rear ends of the base 31. The lower end of the L-shaped plate 32 is fixedly inserted into the inner side of the side groove 33. A lifting cylinder 28 and a guide cylinder 29 are fixedly installed on the upper surface of the base 31. A guide rod 30 is slidably inserted into the upper end of the guide cylinder 29. The upper end of the guide rod 30 and the telescopic end of the lifting cylinder 28 are fixedly connected to a lifting frame 27. The front end of the lifting frame 27 is engaged with the lower surface of the immersion box 10. The up and down movement of the immersion box 10 is controlled by the extension and retraction of the lifting cylinder 28, ensuring that the lower surface of the printing roller 9 can be fully immersed in the water in the immersion box 10. The guide rod 30 will slide up and down along the inner side of the guide cylinder 29, improving the stability of the lifting frame 27 when it moves up and down.

[0042] like Figure 2 , Figure 6 As shown, several inserts 26 are fixedly connected to the lower surface of the soaking box 10, and a lifting plate 24 is fixedly connected to the front end of the lifting frame 27. Several slots 25 are opened on the upper surface of the lifting plate 24. The inserts 26 slide into the inside of the slots 25. After the printing roller 9 rotates and moves away from the top of the soaking box 10, the soaking box 10 can be lifted up to remove it, making it convenient to quickly replace the water in the soaking box 10.

[0043] like Figure 4 , Figure 5 As shown, the elastic mechanism includes a thickened plate 11 fixedly connected to one side of the soaking box 10. A square groove 13 is provided on the inner side of the thickened plate 11. A square block 14 is slidably arranged on the inner side of the square groove 13. A compression spring 15 is provided below the square block 14. The compression spring 15 is located inside the square groove 13. A post 12 is fixedly connected to the upper surface of the square block 14. The upper end of the post 12 is fixedly connected to the lower surface of the contact plate 16.

[0044] like Figure 4 , Figure 5 , Figure 8 , Figure 9 As shown, several reinforcing blocks 40 are fixedly installed on the inner side of the strip-shaped opening 17. A sharpened tip 41 is provided on the side of the reinforcing block 40 near the upper guide plate 19. The sharpened tip 41 guides the water flow to the surface of the lower guide plate 18. The reinforcing blocks 40 increase the structural strength of the inner side of the strip-shaped opening 17, preventing deformation of the strip-shaped opening 17 under the pushing of the printing roller 9. An arc-shaped head 21 is provided on the upper end face of the soft strip 20, and an inner cavity 22 is provided on the inner side of the soft strip 20 near the lower part of the arc-shaped head 21. A chamfered angle 23 is provided on the upper edge of the contact plate 16. The chamfered angle 23 prevents the upper edge of the contact plate 16 from scratching the surface of the printing roller 9.

[0045] The user controls the rotation of the rotating shaft 4 via the first motor 39, causing the wetted printing roller 9 to rotate and move out from the inside of the wettation box 10. During the wettation and movement process, the second motor 6 continuously drives the printing roller 9 to rotate. When rotating, the surface of the printing roller 9 contacts the upper edge of the arc-shaped head 21. The inner cavity 22 causes the surface of the arc-shaped head 21 to be deformed when it is pressed by the printing protrusion on the surface of the printing roller 9, ensuring full contact with the surface of the printing roller 9. During the contact, excess water is guided to flow along the surface of the contact plate 16 to prevent water from flowing out. Water that drips onto other locations and flows onto the surface of the lower guide plate 18 will flow back into the wetting box 10. Water that flows onto the surface of the upper guide plate 19 will flow through the inside of the strip-shaped opening 17 to the surface of the lower guide plate 18. During the above process, the contact plate 16 will also be pushed down, and the square block 14 will slide down along the inside of the square groove 13 to prevent the arc head 21 from pressing the surface of the printing roller 9 with excessive pressure, which would cause the surface of the printing roller 9 to dry. Therefore, while ensuring that the printing roller 9 is wetted, it also prevents water from dripping everywhere on the surface of the printing roller 9, thus protecting the environment of the production workshop.

[0046] After the rotating shaft 4 and the concave frame 5 rotate, the printing roller 9 approaches the surface of the transmission belt, and the printing step can be carried out. The pressure during printing can be adjusted by the rotation angle of the rotating shaft 4 to ensure that the printing force is appropriate.

[0047] A printing method for producing cellulose sponge fabric is also proposed, using the aforementioned apparatus, and includes the following steps:

[0048] S1. First, mix the adhesive with sodium sulfate to obtain a sponge fabric base adhesive that can be used for foaming and molding, with a ratio of 1:3.1.

[0049] S2. Apply the mixed raw adhesive evenly through the mold to form a smooth adhesive layer with a thickness of 1cm.

[0050] S3. Draw a 3D drawing of the plum blossom pattern roller. The plum blossom can be convex or concave. Use 3D printing technology to make a printing roller with a diameter of 100mm, a length of 1.6m, and a pattern depth of 8mm.

[0051] S4. Immerse the printing roller 9 in the immersion box 10 to ensure that the printing roller 9 is wet before contacting the original adhesive, so that there will be no original adhesive sticking after printing.

[0052] S5. Synchronize the printing roller 9 with the conveyor belt speed and apply pressure to the adhesive layer through the rotating shaft 4 so that the pattern is pressed into the original adhesive to a depth of 4-5mm. After the printing roller 9 is separated from the original adhesive, an original adhesive with a three-dimensional plum blossom pattern is formed.

[0053] S6. After printing, the raw rubber is conveyed by a conveyor belt into a high-temperature mother liquor for steaming and molding. The temperature of the mother liquor is controlled at 102℃ and the steaming time is controlled at 30min.

[0054] S7. The raw rubber after steaming is transformed into sponge cloth. After multiple washing processes and the addition of additives, it becomes a finished sponge cloth with a three-dimensional plum blossom texture.

[0055] Here, another printing method for the production of cellulose sponge fabric is also proposed, which uses the above-mentioned apparatus and includes the following steps:

[0056] S1. First, mix the adhesive with sodium sulfate to obtain a sponge fabric base adhesive that can be used for foaming and molding, with a ratio of 1:3.3.

[0057] S2. Apply the mixed raw adhesive evenly through the mold to form a smooth adhesive layer with a thickness of 1cm.

[0058] S3. Draw a 3D drawing of the vertical striped patterned roller. The plum blossom can be convex or concave. Use 3D printing technology to make a printing roller with a diameter of 100mm, a length of 1.6m, and a pattern depth of 5mm.

[0059] S4. Immerse the printing roller 9 in the immersion box 10 to ensure that the printing roller 9 is wet before contacting the original adhesive, so that there will be no original adhesive sticking after printing.

[0060] S5. Synchronize the printing roller 9 with the conveyor belt speed and apply pressure to the adhesive layer through the rotating shaft 4 so that the pattern is pressed into the original adhesive to a depth of 4-5mm. After the printing roller 9 is separated from the original adhesive, an original adhesive with a three-dimensional plum blossom pattern is formed.

[0061] S6. After printing, the raw rubber is conveyed by a conveyor belt into a high-temperature mother liquor for steaming and molding. The temperature of the mother liquor is controlled at 103℃ and the steaming time is controlled at 25min.

[0062] S7. The raw rubber after steaming is transformed into sponge cloth. After multiple washing processes and the addition of additives, it becomes a finished sponge cloth with a three-dimensional vertical stripe pattern.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
