The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0027] According to an embodiment of the present utility model, a toilet paper embossing machine with a roller changing mechanism is provided.

[0028] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1-3As shown, the toilet paper embossing machine with a roller changing mechanism according to an embodiment of the present invention includes a base plate 1, and pillars 2 are fixedly installed at both ends of the top surface of the base plate 1. The two pillars 2 are internally provided with screws 3 with opposite surface threads, and threaded blocks 4 are symmetrically sleeved on the screws 3. The surface of one side of the threaded block 4 passes through the side of the pillar 2 and is fixedly connected to an L-shaped connecting plate 5. The opposite side surfaces of the L-shaped connecting plate 5 are rotatably connected to a rotating drum 6, and an embossing roller 9 is detachably connected between the rotating drums 6.

[0029] In one embodiment, one end of the screw rod 3 passes through the top of the pillar 2 and is connected to the first motor 7. The rotation of the first motor 7 drives the screw rod 3 to rotate, and the rotation of the screw rod 3 drives the threaded block 4 symmetrically sleeved on its surface to make relative movement, so that the embossing rollers 9 connected between the L-shaped connecting plates 5 are closer to or farther away from each other, thereby adjusting the spacing between the embossing rollers 9 accordingly.

[0030] In one embodiment, a second motor 8 is provided on one side of the two L-shaped connecting plates 5 in the same vertical direction. The output end of the second motor 8 passes through the L-shaped connecting plate 5 and is connected to the rotating drum 6. The rotation of the second motor 8 drives the rotating drum 6 to rotate, thereby driving the embossing roller 9 connected between the rotating drums 6 to rotate.

[0031] In one embodiment, a placement rack 11 is fixedly connected to one side of the rotating drum 6 , and a groove 12 is formed on the inner bottom surface of the placement rack 11 .

[0032] In one embodiment, the placement rack 11 is detachably connected to the fixing rack 10 via a screw and a nut, and the combination or separation of the placement rack 11 and the fixing rack 10 facilitates the disassembly and assembly of the embossing roller 9 by personnel.

[0033] In one embodiment, a protrusion 13 is fixedly provided at the bottom of the roller shaft at both ends of the embossing roller 9, and when the embossing roller 9 is installed, the protrusion 13 is placed in the groove 12. By rotating the protrusion 13 at the bottom of the roller shaft into the groove 12, the roller shaft is prevented from idling when the rotating drum 6 rotates, which causes the embossing roller 9 to be unable to rotate continuously, thereby affecting the embossing quality of the toilet paper.

[0034] Working principle: In actual use, first adjust the distance between the upper and lower embossing rollers 9 according to the actual thickness of the toilet paper, and drive the screw rod 3 to rotate through the rotation of the first motor 7, and the rotation of the screw rod 3 drives the threaded blocks 4 symmetrically sleeved on its surface to make relative movement, so that the embossing rollers 9 connected between the L-shaped connecting plates 5 are moved closer or farther away from each other, and then adjust the distance between the embossing rollers 9 accordingly, so as to avoid the situation in which the toilet paper is squeezed too much during embossing and thus damaged, or the situation in which the embossing quality is poor due to insufficient contact with the embossing rollers 9; when the embossing rollers 9 are embossed, the embossing rollers 9 are adjusted. When cleaning and maintaining or replacing the embossing roller 9 with a different pattern, twist the screw to separate the fixing frame 10 from the placement frame 11, and then remove the embossing roller 9. After the cleaning and maintenance of the embossing roller 9 is completed or a new embossing roller 9 is replaced, the roller shafts at both ends of the embossing roller 9 are placed in the placement frame 11, and the protrusions 13 at the bottom of the roller shaft are turned into the groove 12 to prevent the roller shaft from idling when the drum 6 rotates, causing the embossing roller 9 to be unable to rotate continuously, thereby affecting the embossing quality of the toilet paper. The device as a whole has the advantages of adjustable embossing roller spacing, convenient disassembly and assembly of the embossing rollers, and flexible use.
