[0028] Limiting assembly is arranged between base 5 and movable seat 7, supports the vertical movement of movable seat 7, adjusts the height of movable seat 7 by lifting device, so that the height of glue cylinder cleaning piece on movable seat 7 is consistent with the height of glue cylinder, and the height of glue cylinder cleaning piece is flexible by rising and moving down to clean glue cylinder head.

[0029] Specifically, glue cylinder cleaning piece includes cleaning support 2, cleaning support 2 upper end is equipped with cleaning block 3, cleaning block 3 is fixedly connected with cleaning support 2, cleaning block 3 is U-shaped, and drip tray 4 is arranged below cleaning block 3, and drip tray 4 is fixedly connected with cleaning support 2.Glue cylinder on glue dispenser translates to the side edge of cleaning support 2 along with sliding block, cleaning block 3 on the upper end of cleaning support 2 is sleeved outside glue cylinder head, lifting device controls rotating disc 1 to move down, cleaning block 3 scrapes off the glue solution attached to glue cylinder head, and the glue solution drops into drip tray 4 to prevent the pollution of table top.

[0030] In the preferred scheme, the lower end of the cleaning support 2 is fixedly connected with a bolt plate, and a fixing bolt is assembled on the bolt plate. The fixing bolt penetrates through the bolt plate and is threadedly connected with a bolt hole formed in the upper end of the rotating disc 1. When the cleaning support 2 is removed from the upper end of the rotating disc 1, the bolt on the bolt plate is simply screwed out of the bolt hole in the upper end of the rotating disc 1.

[0031] The specific structure of the cleaning member switching device will be described as follows:

[0032] The cleaning member switching device comprises a rotating shaft 8 and a first driving member. The rotating shaft 8 is fixedly connected with the lower end of the rotating disc 1 and penetrates through the movable seat 7 and is rotatably connected with the movable seat 7.

[0033] The first driving member comprises a first motor 10, a second gear 11 and a first gear 9. The first gear 9 is fixedly connected with the lower end of the rotating shaft 8, the first motor 10 is fixedly connected with the lower end of the movable seat 7, the second gear 11 is fixedly connected with the output end of the first motor 10, and the first gear 9 is engaged with the second gear 11.

[0034] The first motor 10 drives the second gear 11 to rotate, and the second gear 11 is engaged with the first gear 9 during rotation, thereby driving the rotating shaft 8 to rotate. Since the rotating shaft 8 is fixed with the rotating disc 1, when the rotating shaft 8 rotates, the rotating disc 1 also rotates, thereby switching the cleaning member on the rubber cylinder of the rotating disc 1.

[0035] The lifting device adopts a gear and plate cooperation mode to adjust the height of the movable seat 7. Specifically, the lifting device comprises a gear plate 16 and a second driving member. The upper end of the gear plate 16 is fixedly connected with the movable seat 7.

[0036] The second driving member comprises a second motor 14 and a third gear 15. The third gear 15 is rotatably connected in an installation groove 17 formed in the side of the base 5. The second motor 14 is fixedly connected with the outside of the base 5, and the output end of the second motor 14 is fixedly connected with the installation groove 17.

When the gear plate 16 ascends or descends, the movable seat 7 fixedly connected with the gear plate 16 also moves.

[0038] In order to avoid the movable seat 7 from moving during lifting, a limiting assembly is required to limit the movable seat 7. Specifically, the limiting assembly comprises at least one guide rod 12. The guide rod 12 is fixedly connected with the movable seat 7, penetrates through the base 5 at the lower end, and is slidably connected with the base 5. When the movable seat 7 ascends or descends, the guide rod 12 fixedly connected with the lower end of the movable seat 7 also moves, and the base 5 guides the guide rod 12 through cooperation.

[0039] In a better implementation, the lower end of the guide rod 12 is sleeved with a nut 13, and the nut 13 is threadedly connected with the guide rod 12. The nut 13 fixed at the lower end of the guide rod 12 is used for limiting the base 5, so as to avoid separation of the base 5 from the guide rod 12. When the movable seat 7 is removed from above the base 5, the nut 13 can be screwed out from the outside of the guide rod 12.

[0040] The working principle of the present application is as follows:

[0041] The height of the movable seat 7 is adjusted by the lifting device, so that the rubber tube cleaning piece on the movable seat 7 is consistent with the height of the rubber tube. The rubber tube cleaning piece is raised and lowered to clean the head of the rubber tube, and the height is flexible. The detachable installation mode of the rubber tube cleaning piece facilitates replacement of the rubber tube cleaning piece. The rotating disc 1 is controlled to rotate by the cleaning piece switching device, and the rotating disc 1 switches the rubber tube cleaning piece during rotation, so that the cleaning efficiency is high.

[0042] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principle of the present application.
