DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-Figure 3As shown, a transmission device for an embossing roller comprises a base plate 1, the left and right parts of the top of the base plate 1 are fixedly connected with a mounting plate 11, the bottom of the mounting plate 11 is rotatably connected with a rotating shaft 12, the outer wall of the rotating shaft 12 is fixedly connected with a driven roller 13, the left part of the rotating shaft 12 is fixedly connected with a driven gear 14, the top at the right end of the right mounting plate 11 is fixedly connected with a limiting mechanism 2, the outer wall of the limiting mechanism 2 is fixedly connected with a transmission mechanism 3, the limiting mechanism 2 comprises a fixed plate 21 and a rotating rod 27, one end of the fixed plate 21 is fixedly connected to the top at the right end of the right mounting plate 11, the outer wall of the rotating rod 27 is rotatably connected to the top of the mounting plate 11, the right end of the rotating rod 27 is fixedly connected with a hand wheel 271, and the transmission mechanism 3 comprises two supporting plates 31, and the middle part of the supporting plate 31 is fixedly connected to the outer wall of the rotating rod 27.

[0025] The transmission mechanism 3 drives each embossing roller to rotate and emboss the paper. When it is necessary to replace the embossing roller with a different style, the limiting mechanism 2 is used to quickly replace and fix the embossing roller.

[0026] like Figure 2 , Figure 3 As shown, the inner wall of the fixed plate 21 is threadedly connected with a threaded rod 22, and the top of the threaded rod 22 is rotatably connected with a movable plate 24. The left and right parts of the fixed plate 21 are movably sleeved with guide rods 23, and the top of the guide rod 23 is fixedly connected to the bottom end of the movable plate 24. The top of the movable plate 24 is fixedly connected with a fixed block 25, and the inner wall of the fixed block 25 is clamped with a clamping block 26, and the axis of the clamping block 26 is fixedly connected to the right part of the rotating rod 27.

[0027] The threaded rod 22 is rotated to move downward on the inner wall of the fixed plate 21, driving the movable plate 24 to move downward synchronously. The movable plate 24 drives the guide rod 23 to slide downward on the inner wall of the fixed plate 21 synchronously. The guide rod 23 guides the movable plate 24 so that the movable plate 24 will not deviate when moving downward. At the same time, the movable plate 24 drives the fixed block 25 to move synchronously, so that the inner wall of the fixed block 25 is no longer engaged with the outer wall of the clamping block 26. Then the hand wheel 271 can be rotated to drive the rotating rod 27 to rotate synchronously.

[0028] like Figure 2-Figure 4 As shown, a spring 28 is fixedly connected to the left portion of the rotating rod 27 , a positioning block 29 is fixedly connected to the right end of the spring 28 , and an outer wall of the positioning block 29 is clamped with the top at the left end of the left mounting plate 11 .

[0029] When the rotating rod 27 rotates, the spring 28 and the positioning block 29 are driven to rotate synchronously, so that the positioning block 29 is no longer engaged with the inner wall of the mounting plate 11, and the spring 28 contracts. After rotating 180 degrees, under the action of the elastic force of the spring 28, the outer wall of the positioning block 29 is again plugged into the inner wall of the mounting plate 11. At this time, the hand wheel 271 can be rotated, thereby the positioning block 29 is used for positioning, avoiding excessive or insufficient rotation, and achieving the effect of positioning.

[0030] like Figure 2 , Figure 5 As shown, a fixing frame 32 is fixedly connected to the top of the right support plate 31, a motor 33 is fixedly connected to the inner wall of the fixing frame 32, an outer wall of the output end of the motor 33 is rotatably connected to the inner wall of the support plate 31, an embossing roller 331 is fixedly connected to the outer wall of the output end of the motor 33, and a gear 332 is fixedly connected to the left part of the output end of the motor 33.

[0031] By rotating the rotating rod 27, the support plate 31 is driven to rotate synchronously, and the support plate 31 drives the embossing roller 1 331 and the embossing roller 2 362 to rotate synchronously. Because the gear 2 363 and the driven gear 14 are in a meshing state, when the gear 2 363 rotates with the embossing roller 2 362, the driven gear 14 is rotated. When the gear 2 363 rotates to a certain position, it is no longer in contact with the driven gear 14. Subsequently, under the action of the elastic force of the spring 28, the outer wall of the positioning block 29 is again plugged into the inner wall of the mounting plate 11. At this time, the hand wheel 271 can be stopped. At this time, the outer wall of the gear 1 332 is meshed with the outer wall of the driven gear 14, thereby completing the replacement of the embossing roller and achieving the effect of replacing the embossing roller.

[0032] like Figure 2 , Figure 5 As shown, the right part of the output end of the motor 33 is fixedly connected to the driving wheel 34, the outer wall of the driving wheel 34 is transmission-connected to the transmission belt 35, the bottom of the transmission belt 35 is transmission-connected to the driven wheel 36, the axis of the driven wheel 36 is fixedly connected to the second rotating shaft 361, the outer wall of the second rotating shaft 361 is rotationally connected to the bottom of the mounting plate 11, the outer wall of the second rotating shaft 361 is fixedly connected to the second embossing roller 362, the left part of the second rotating shaft 361 is fixedly connected to the second gear 363, and the outer wall of the second gear 363 is meshed with the outer wall of the driven gear 14.

[0033] By starting the motor 33, the output end of the motor 33 drives the driving wheel 34 to rotate synchronously, the driving wheel 34 drives the transmission belt 35 to rotate synchronously, the transmission belt 35 drives the driven wheel 36 to rotate synchronously, the driven wheel 36 drives the second shaft 361 to rotate, the second shaft 361 drives the embossing roller 2 362 and the second gear 363 to rotate synchronously, so that the second gear 363 is meshed with the driven gear 14, driving the driven gear 14 to rotate synchronously, thereby embossing the paper between the driven roller 13 and the second embossing roller 362, achieving the embossing effect.

[0034] The working principle of the utility model is as follows: when in use, the paper to be embossed is placed between the driven roller 13 and the embossing roller 362, and then the motor 33 can be started, and the output end of the motor 33 drives the embossing roller 1 331 and the gear 1 332 to rotate synchronously, and at the same time, the output end of the motor 33 drives the driving wheel 34 to rotate synchronously, and the driving wheel 34 drives the transmission belt 35 to rotate synchronously, and the transmission belt 35 drives the driven wheel 36 to rotate synchronously, and the driven wheel 36 drives the rotating shaft 361 to rotate, and the rotating shaft 361 drives the embossing roller 362 and the gear 363 to rotate synchronously, so that the gear 36 3 meshes with the driven gear 14, driving the driven gear 14 to rotate synchronously, thereby embossing the paper between the driven roller 13 and the embossing roller 2 362, achieving the embossing effect. When the embossing style needs to be changed, the threaded rod 22 is rotated to move the threaded rod 22 downward on the inner wall of the fixed plate 21, driving the movable plate 24 to move downward synchronously, and the movable plate 24 drives the guide rod 23 to slide downward on the inner wall of the fixed plate 21 synchronously. The guide rod 23 guides the movable plate 24 so that the movable plate 24 will not deviate when moving downward, and at the same time, the movable plate 24 drives the fixed block 25 to move synchronously The inner wall of the fixing block 25 is no longer engaged with the outer wall of the block 26, and then the hand wheel 271 can be rotated to drive the rotating rod 27 to rotate synchronously, and the rotating rod 27 drives the spring 28 and the positioning block 29 to rotate synchronously, so that the positioning block 29 is no longer engaged with the inner wall of the mounting plate 11, so that the spring 28 contracts, and at the same time, the rotating rod 27 drives the supporting plate 31 to rotate synchronously, and the supporting plate 31 drives the embossing roller 1 331 and the embossing roller 2 362 to rotate synchronously. Because the gear 2 363 and the driven gear 14 are in a meshing state, therefore, when the gear 2 363 rotates with the embossing roller 2 362, the driven gear 14 rotates When the gear 2 363 rotates to a certain position, it no longer contacts the driven gear 14. Subsequently, under the action of the elastic force of the spring 28, the outer wall of the positioning block 29 is plugged into the inner wall of the mounting plate 11 again. At this time, the handwheel 271 can be stopped. At this time, the outer wall of the gear 1 332 is meshed with the outer wall of the driven gear 14, thereby completing the replacement of the embossing roller, which has the effect of replacing the embossing roller. Subsequently, the outer wall of the clamping block 26 is plugged into the inner wall of the fixing block 25 to complete the limiting function, so that the rotating rod 27 cannot rotate, which has the effect of limiting the position, thereby greatly improving the user experience.
