[0009] A further improvement is that a limiting device is provided between the installation block and the installation plate to prevent the installation block from slipping out of the installation slot.

[0010] A further improvement is that the limiting device includes four limiting grooves opened on the mounting plate and respectively connected to the mounting slots, and a limiting plate with one end arranged on the side end surface of the mounting block and the other end slidingly matched with the limiting grooves.

[0011] A further improvement is that a matching inclined surface is arranged at the end of the T-shaped connecting plate close to the front end limiting plate.

[0012] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: after the cleaning brush is repeatedly used for a period of time, when the cleaning brush needs to be replaced, the mounting bolt is tightened by a tool to release the connection between the front end limiting plate and the mounting plate, and the front end limiting plate is removed from the mounting plate, and then the T-shaped connecting plate is pushed toward the front end of the mounting plate, and the inclined surface cooperates with the mounting slot to push the mounting block to move toward the end of the compression spring in the mounting slot, thereby releasing the cooperation between the mounting block and the mounting slot, and the T-shaped connecting plate can be taken out from the T-shaped mounting hole, thereby removing the cleaning brush from the lower end of the electric push rod, and installing a new brush connecting plate with a brush head on the mounting plate.

[0013] Further effect: when the T-shaped connecting plate needs to be installed in the T-shaped mounting hole, the T-shaped connecting plate is pushed into the T-shaped mounting hole from the rear end to the front end of the mounting plate. When the T-shaped connecting plate slides toward the front end limiting plate in the T-shaped mounting hole, the T-shaped connecting plate abuts against the inclined surface, and as the T-shaped connection slides, the mounting block slides toward the end of the compression spring. The compression spring is compressed to generate elastic potential energy. When the T-shaped connecting plate is pushed against the front end limiting plate, the mounting block is pushed to engage with the mounting slot by the elastic potential energy released by the compression spring. The front end limiting plate limits the T-shaped connecting plate from sliding forward in the T-shaped mounting hole, and the right-angle surface of the mounting block cooperates with the mounting slot to limit the backward sliding of the T-shaped connecting plate.

[0014] Further effect: the matching inclined surface can cooperate with the inclined surface of the installation block when the T-shaped connecting plate is pushed into the T-shaped installation hole, so that the installation block can slide toward the end of the compression spring more easily in the installation slot.

[0015] Further effect: through the cooperation between the limiting plate and the limiting groove, when the compression spring pushes the installation block to move toward the end of the T-shaped connecting plate, the installation block is prevented from slipping out of the installation groove.

[0027] A limiting device is provided between the mounting block 21 and the mounting plate 13 to prevent the mounting block 21 from slipping out of the mounting slot 20 .

[0028] The limiting device includes four limiting grooves 25 opened on the mounting plate 13 and respectively connected to the mounting slots 20 , and a limiting plate 26 with one end disposed on the side surface of the mounting block 21 and the other end slidingly matched with the limiting grooves 25 .

[0029] The end of the T-shaped connecting plate 15 close to the front end limiting plate 18 is provided with a matching inclined surface 27 .

[0030] The working principle of the utility model is as follows: before the laminating machine coats the cardboard, the cardboard is placed on the horizontal plate 1, the electric push rod 12 pushes the brush head 17 at the lower end to abut against the upper end surface of the cardboard, and the threaded rod 8 is driven to rotate by starting the motor 5, so that the threaded sleeve 9 drives the electric push rod 12 to move horizontally through the moving rod 10, thereby driving the brush head 17 to clean the upper end surface of the cardboard. After the brush head 17 is repeatedly used for a period of time, the brush head 17 is easily bent and the hair is fried due to the frequent squeezing of the brush head 17 with the carton and moving on the carton. At this time, the mounting bolt 19 is screwed by a tool to release the connection between the mounting bolt 19 and the front end limiting plate 18 and the mounting plate 13, and the front end limiting plate 18 is connected to the mounting plate 13. The control plate 18 is removed from the mounting plate 13, and then the T-shaped connecting plate 15 is pushed toward the front end of the mounting plate 13 (by pushing the brush mounting plate 13 by hand or against the front end of the T-shaped connecting plate 15), and the inclined surface 24 cooperates with the mounting slot 20 to push the mounting block 21 to move toward the end of the compression spring 22 in the mounting slot 20, thereby releasing the cooperation between the mounting block 21 and the mounting slot 20, and the T-shaped connecting plate 15 can be pushed out from the front end of the mounting plate 13 through the T-shaped mounting hole 14, so that the cleaning brush is removed from the lower end of the electric push rod 12, and then the mounting bolt 19 is first installed between the front end limiting plate 18 and the front end of the mounting plate 13, and then the new brush connecting plate 16 with the brush head 17 is installed. The T-shaped connecting plate 15 is pushed into the T-shaped mounting hole 14 from the rear end to the front end of the mounting plate 13. The T-shaped connecting plate 15 first cooperates with the inclined surface 24 to push each mounting block 21 to move toward the end of the compression spring 22 in the mounting slot 20. The compression spring 22 contracts to generate elastic potential energy. When the T-shaped connecting plate 15 abuts against the front end limiting plate 18, the mounting slot 20 corresponds to the position of the matching slot 23. The compression spring 22 releases the elastic potential energy to push the mounting block 21 to move toward the end of the T-shaped connecting plate 15, so that the mounting block 21 is engaged with the matching slot 23. The T-shaped connecting plate 15 is limited to slide forward in the T-shaped mounting hole 14 by the front end limiting plate 18, and the mounting block 21 is engaged with the matching slot 23. The engagement limits the T-shaped connecting plate 15 from sliding backward in the T-shaped mounting hole 14, thereby fixing the T-shaped connecting plate 15 on the mounting plate 13 and located in the T-shaped mounting hole 14 to complete the brush replacement operation. The brush can be replaced in time to improve the cleaning effect of the cleaning brush on impurities on the carton; the matching inclined surface 27 can cooperate with the inclined surface 24 of the mounting block 21 when the T-shaped connecting plate 15 is pushed into the T-shaped mounting hole 14, so that the mounting block 21 can slide more easily in the mounting slot 20 toward the end of the compression spring 22; through the cooperation of the limiting plate 26 and the limiting slot 25, when the compression spring 22 pushes the mounting block 21 to move toward the end of the T-shaped connecting plate 15, the mounting block 21 can be prevented from slipping out of the mounting slot 20.
