Description

Technical Field

[0001] This utility model relates to the field of humidifying paper towel processing, and in particular to an embossing roller structure for humidifying paper towel processing. Background Technology

[0002] Embossing rollers for moisturizing wipes are roller devices used in wet wipe production equipment to press specific patterns or structures onto the surface of moist wipes. Embossing improves the fluffiness, absorbency, tensile strength, or feel of the wipes. Some embossed structures can assist in subsequent processing, such as folding and slitting. The embossing section in a wet wipe production line is especially suitable for products with special requirements for thickness and softness, such as medical wipes, makeup remover wipes, and household cleaning wipes.

[0003] A search revealed that Chinese Patent Publication No. CN220813030U discloses a wet wipe embossing machine with adjustable embossing depth. When the wet wipe material passes between the guide bottom roller and the guide top roller, the thickness of the wet wipe material can be measured by a laser rangefinder, which makes it easy to adjust the specific embossing depth accordingly, ensuring more precise adjustment of the embossing depth.

[0004] In the above technical solution, the thickness of the wet wipe is detected by the guide roller and the laser rangefinder to facilitate the adjustment of the embossing depth. However, after long-term operation, the raised or concave texture of the embossing roller will leave fiber residue, which cannot provide a cleaning function for the embossing roller. This will result in the retention of residue on the surface of the wet wipe during subsequent embossing operations, reducing the embossing quality and effect of the wet wipe. Therefore, an embossing roller structure for processing moisturizing paper towels is proposed to solve the above problems. Utility Model Content

[0013] As a further description of the above technical solution:

[0014] The annular groove is formed at the bottom of the fixed frame, and the top end of the rotating shaft is rotatably connected to the inner wall of the annular groove.

[0015] As a further description of the above technical solution:

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of an embossing roller structure for processing moisturizing paper towels, including a base 1, a bracket 2 fixedly connected to the base 1, two sets of brackets 2 for supporting embossing rollers 5, guide frames on the left and right sides of the brackets 2, guide rollers for conveying moisturizing paper towels on the guide frames, a mounting plate 3 fixedly connected to the outer wall of the brackets 2, a motor 4 fixedly connected to the outer wall of the mounting plate 3, and embossing rollers 5 rotatably connected to the outer wall of the brackets 2. Two sets of embossing rollers 5 are provided, their surfaces are decorated with raised patterns, and the two sets of embossing rollers 5 are driven by meshing gears. The motor 4 is fixedly connected to the bottom embossing roller 5, and a drive belt 6 is driven by the embossing roller 5. The drive belt 6 is connected to the top embossing roller 5, and a bidirectional lead screw 7 is driven by the drive belt 6. A limit rod 8 is fixedly connected to the outer wall of the brackets 2, and the outer wall of the bidirectional lead screw 7 is threaded with... The movable seat 9 has its inner wall slidably connected to the outer wall of the limiting rod 8. A fixed frame 12 is provided on the top of the movable seat 9, and a rotating shaft 13 is provided at the bottom of the fixed frame 12. A connecting plate 14 is fixedly connected to the bottom of the rotating shaft 13, and a mounting shell 15 is fixedly connected to the bottom of the connecting plate 14. The inner wall of the mounting shell 15 is hollow and is used to transmit gas. Multiple sets of equally spaced through holes are opened on the side near the cleaning bristles 16 so that the cleaning bristles 16 can assist the airflow impact to clean the embossing roller 5. The cleaning bristles 16 are fixedly connected to the side wall of the mounting shell 15, and a connecting pipe 22 is fixedly connected to the side of the mounting shell 15 away from the cleaning bristles 16. The connecting pipe 22 is connected to an external air pump through a pipe. The air pump can draw in air and transmit it to the inside of the connecting pipe 22 through the pipe. A flexible hose can be selected for connection.

[0033] Reference Figures 3-5 The surface of the connecting plate 14 is provided with a cleaning promotion component, which includes an annular groove 17. The annular groove 17 is opened at the bottom of the fixed frame 12. The top end of the rotating shaft 13 is rotatably connected to the inner wall of the annular groove 17. A coil spring 18 is fixedly connected to the inner wall of the annular groove 17. The movable end of the coil spring 18 is fixedly connected to the outer wall of the rotating shaft 13. A clearance groove 20 is opened on the side wall of the limiting rod 8. The clearance groove 20 allows the limiting rod 8 to provide a moving limit guide for the moving seat 9, while facilitating the contact between the toothed block 21 and the protrusion 19. A toothed block 21 is fixedly connected to the inner wall of the clearance groove 20. Several sets of toothed blocks 21 are provided and are evenly distributed inside the limiting rod 8. A protrusion 19 is fixedly connected to the outer wall of the rotating shaft 13. The protrusion 19 is made of a relatively hard rubber material and can be inserted into the clearance groove 20 to contact the toothed block 21.

[0034] Reference Figures 3-5The top of the movable seat 9 has a rectangular hole 10, and a rectangular rod 11 is inserted into the inner wall of the rectangular hole 10. The top of the rectangular rod 11 is fixedly connected to the bottom of the fixed frame 12. The rectangular rod 11 can be inserted into or removed from the rectangular hole 10, which can quickly remove or install the fixed frame 12 from the base 1, thereby facilitating the removal of the cleaning parts as a whole, and making it easier for the embossing roller 5 to perform embossing operations on the wet paper towels.

[0035] Working principle: Insert the rectangular rod 11 into the rectangular hole 10. Fix the bracket 12 on the movable seat 9. Connect the output end of the air pump to the connecting pipe 22 through the external telescopic tube. Start the motor 4. The running speed of the motor 4 is pre-adjusted by the PLC controller. The two sets of embossing rollers 5 rotate slowly. The transmission belt 6 drives the bidirectional lead screw 7 to rotate, which drives the movable seat 9 to move back and forth. This allows the cleaning bristles 16 to clean the surface of the rotating embossing rollers 5. During the movement of the movable seat 9, since the multiple sets of toothed blocks 21 are adjacent to each other and have a certain distance, when the toothed block 21 contacts the protrusion 19, it can squeeze it, causing the rotating shaft 13 to rotate under force, which stretches the coil spring 18. When the protrusion 19 contacts the next toothed block 21, the coil spring 18 has time to reset, which drives the cleaning bristles 16 to bend to a certain extent. The air pump is in the starting state at this time. Air is sprayed out through the through hole, which works with the cleaning bristles 16 to clean the surface of the embossing rollers 5, avoiding fiber residue on the surface of the embossing rollers 5 and improving the subsequent embossing effect.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
