The grooves B11 are uniformly distributed along the length direction of the surface of the sponge B1, and the number of the grooves B11 is set according to needs, such as a plurality of grooves. Since the two side surfaces of the groove B11 can be arranged vertically or approximately vertically, a cleaning blade B13 can be formed at the interface between the surface B12 and the side surface B11 of the sponge B1. Because cavernosum B1 forms more closely knit structure with the mould contact surface when the shaping, like this when the clearance, this clearance scraper B13 forms fine cutting action with stubborn rubbish on the clean face, as shown in fig. 4, when cavernosum B1 rotates to the F direction, this clearance scraper B13 can with form before the clean face and scrape the cutting action, can clear up stubborn rubbish from the reality, even can not be once clear up qualitatively, also can clear up great stubborn rubbish cutting mode, thereby improve the stubborn rubbish effect of clearance.

Specifically, the sponge roller forming die comprises a sponge forming sleeve 20 for manufacturing a sponge body and left and right fixing covers for fixing a roller shaft core 21 during forming, wherein the sponge forming sleeve 20 is provided with a die cavity with the diameter larger than that of the roller shaft core, after the left and right fixing covers are fixed with the sponge forming sleeve 20 and the roller shaft core 21, a sponge body forming cavity with the same distance between the surface of the roller shaft core and the die cavity is formed, the inner wall of the die cavity is provided with a sponge roller structure, namely the inner wall of the die cavity is provided with a group of wavy cambered surface structures at least arranged along the radial square section of the roller, and the structures in the embodiment can be formed on the surface of the sponge body in the forming process.

Specifically, the left fixing cover 23 and the right fixing cover 22 are respectively provided with two fixing steps, namely a first fixing step 231 and a second fixing step 231, wherein the first fixing step 231 is fixed with the roller shaft core 21 and is positioned around the shaft center of the sponge setting sleeve 20, and the second fixing step 232 is fixed with the sponge setting sleeve 20. The first fixing step 231 and the second fixing step 231 are coaxially disposed. A sealing ring (not shown in the drawings) is arranged between the second fixing step 231 and the sponge shaping sleeve 20, so that the phenomenon that the sponge is foamed and exposed to affect the appearance and the subsequent processing process during the forming process is avoided.

The wave-shaped cambered surface structure comprises three groups of wave-shaped cambered surface structures. Each group of the wave-shaped cambered surface structures comprises a first wave-shaped cambered surface 112 and a second wave-shaped cambered surface 113 arranged between the two first wave-shaped cambered surfaces 112. The first wavy arc surface 112 and the second wavy arc surface 113 are uniformly distributed in the circumferential direction of the surface of the cylindrical sponge 11. The wave-shaped cambered surface structure is provided with a wave-shaped cambered surface along the axial length direction of the roller body 10 along the length direction.

Each wavy arc surface is formed by a plurality of convex strips arranged at intervals, grooves are arranged between every two adjacent convex strips, the number of the convex strips and the number of the grooves are arranged according to requirements, and the first wavy arc surface 112 is formed by distributing two convex strips and three grooves at intervals in the embodiment; the second wavy arc surface 113 is formed by three convex strips and four grooves which are distributed at intervals.

Because the wavy cambered surface structure is distributed on the surface of the sponge roller, when the sponge roller is used, the wavy cambered surface structure and the cleaning surface generate larger friction force, so that garbage is easier to clean. Meanwhile, the clearance between each adjacent first wavy cambered surface 112 and each adjacent second wavy cambered surface 113 is different, when the roller works, the surface of the roller and the cleaning surface form friction force and clearance change, and stubborn garbage is easier to clean.

Through tests, the depth of the groove (not shown in the attached drawing) is 1-2mm, the width of the groove is larger than 0.5mm, the width of the convex strip is larger than 0.5mm, and the cleaning effect is better. The width of the raised strips is the same as that of the grooves, so that the cleaning effect can be further improved.

According to the requirement, the area of the wave-shaped cambered surface occupies 1/4-1/3 of the circumferential surface of the cylindrical sponge, and the cleaning effect is the best. According to the requirement, the wavy cambered surface is spirally or arcuately arranged along the length direction of the cylindrical sponge 11, so that only part of the contact surface is contacted with the cleaning contact surface during cleaning, the working load of a motor on the roller can be reduced, and the cleaning effect is not influenced.

According to the requirement, the sponge surface is distributed with inner layer areas which expose the inner layer of the sponge, and the inner layer areas are distributed at intervals. Because cavernosum inner layer region has the clearance, produces great frictional force with the clean face contact, and the cavernosum surface is less because foam molding time and mould contact form closely knit smooth top layer friction, can improve the roughness of cavernosum during above-mentioned setting, has the utilization to stubborn rubbish clearance.

The sponge mould can be further provided with grooves B11 and grooves B11 which are connected smoothly, so that the cleaning effect can be realized, and compared with the experiment, the effect of the embodiment is slightly inferior to that of the embodiment.
