DETAILED DESCRIPTION

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] See also Figures 1 to 9 The utility model provides a technical solution: a cardboard dust and chip removal device for a contact line machine conveying mechanism, comprising a conveyor 1, an upper fixed seat 2, a lower fixed seat 3, an air supply nozzle 4, an anti-static bellows 5 and a dust hood 6. The upper and lower ends of the frame of the conveyor 1 are respectively fixed with the upper fixed seat 2 and the lower fixed seat 3 through brackets, the air supply nozzle 4 and the anti-static bellows 5 are fixed on the side of the bracket on one side of the upper fixed seat 2, and the dust hood 6 is fixed on the side of the bracket on the other side of the upper fixed seat 2. The middle part of the upper fixed seat 2 is provided with an area for cardboard transportation, and the bottom of the upper fixed seat 2 is symmetrically provided with a pressing mechanism for resisting cardboard. The conveyor belt surface of the conveyor 1 is fixed with an anti-slip pad 7 for increasing friction.

[0033] One side of the air supply nozzle 4 is connected to an air supply pipe 8, which passes through the interior of the upper fixed base 2 and is connected to the air supply end of the first fan 9. The other end of the first fan 9 is connected to the filter assembly on the top of the upper fixed base 2 through a pipeline;

[0034] One side of the dust hood 6 passes through the interior of the upper fixing base 2 through the first negative pressure pipe 10 and is connected to the interior of the dust bag 11. A connecting cover 12 is installed on the outside of one side of the dust bag 11. One side of the connecting cover 12 is connected to the negative pressure end of the second fan 13 through a pipe. The air supply end of the second fan 13 passes through the exhaust pipe 14 to the top of the upper fixing base 2;

[0035] Cleaning rollers 16 for cleaning the conveyor belt are installed on both sides of the middle part of the lower fixed seat 3 through support blocks 15, and brush heads 17 are installed at equal intervals on the surface of the cleaning rollers 16. A dust collecting hood 18 for collecting dust is also fixedly installed in the middle part of the lower fixed seat 3. The dust collecting hood 18 passes through the interior of the upper fixed seat 2 and is connected to the interior of the dust storage bag 11 through a second negative pressure pipe 19. A controller 20 is fixed at the front end of the lower fixed seat 3. Considering that the conveyor 1 for transporting cardboard at present mainly transports the cardboard through the conveyor belt in conjunction with the pressing mechanism, since there are dust and paper scraps left after daily storage or trimming of the cardboard, and the dust and paper scraps not only affect the working environment of the workers during the transportation process, but also pose a hidden danger to the workers' health, the utility model provides an air supply nozzle 4, an anti-static bellows 5 and a dust collecting hood 6 to cooperate with each other to transport the cardboard to the The cardboard processed by the line-touching machine has the function of removing dust and paper scraps, preventing the dust and debris on the surface of the cardboard from being blown up and affecting the health of the environmental air during the downward pressing process of the line-touching machine. The brush head 17 and the dust collecting hood 18 are used to remove the paper scraps and dust attached to the anti-slip pad 7 on the surface of the conveyor belt, preventing the anti-slip pad 7 itself from adhering to dust and paper scraps and then re-adhering to the surface of the conveyed cardboard. The cardboard will be conveyed through the conveyor belt of the conveyor 1. During the conveying process, the compression structure will prevent the cardboard from warping and deflecting. During the conveying process, the air supply nozzle 4 and the anti-static bellows 5 both convey airflow to the surface of the cardboard, thereby blowing away the dust and debris attached to the cardboard itself, and then using the negative pressure inside the dust collection hood 6 to transport the dust and debris to the inside of the dust storage bag 11. The air will pass through the gap of the dust storage bag 11 and then be discharged by the second fan 13 in conjunction with the exhaust pipe 14.

[0036] Among them, the front end of the upper fixed seat 2 is rotatably connected to the front cover 21 through a damping hinge, and a reserved groove for installing the perspective window 22 is opened in the middle of the front cover 21. By setting the front cover 21 in a hinged manner, it is convenient for the user to open the front cover to replace the dust storage bag 11.

[0037] Among them, the filter assembly includes a concave frame 32, a first filter screen 33, an activated carbon filter plate 34 and a second filter screen 35. Two groups of supporting blocks are symmetrically fixed inside the concave frame 32. The number of each group of supporting blocks is two. The two groups of supporting blocks are respectively fixed with the first filter screen 33 and the second filter screen 35 by screws. The activated carbon filter plate 34 is in contact with the first filter screen 33 and the second filter screen 35. By setting the filter assembly, the airflow delivered by the air supply nozzle 4 is filtered, preventing dust in the air from being inhaled and adhering to the surface of the cardboard through the airflow. The process of external air entering is summarized and filtered multiple times through the first filter screen 33, the activated carbon filter plate 34 and the second filter screen 35 in turn to ensure that the delivered air does not contain dust or paper scraps.

[0038] Among them, an air outlet is fixed on one side of the static-eliminating bellows 5 by screws, and a negative ion wind rod 36 is fixed inside the static-eliminating bellows 5. The lower end of the negative ion wind rod 36 is connected to the driver circuit through a wire. The back of the static-eliminating bellows 5 is provided with a ventilation groove for air to enter, and a dust filter is fixed inside the ventilation groove. By arranging the negative ion wind rod 36 inside the static-eliminating bellows 5, static electricity is removed from the paper scraps electrostatically adsorbed on the surface of the cardboard, thereby avoiding the disadvantage that the paper scraps are difficult to blow towards the dust cover 6 after static adsorption.

[0039] Among them, the clamping mechanism includes a support rod 23, an electric push rod 24, a clamping block 25, a guide shaft 26 and a dust-proof telescopic sleeve 27. The electric push rod 24 is fixed inside the support rod 23. The telescopic part of the electric push rod 24 passes through the bottom of the support rod 23 and is fixedly connected to the clamping block 25. A guide shaft 26 is rotatably connected to the middle of the clamping block 25. Limiting members are installed at the front and rear ends of the guide shaft 26. A dust-proof telescopic sleeve 27 is installed between the support rod 23 and the clamping block 25. By setting the clamping mechanism, the cardboard transported by the conveyor 1 is compressed, thereby avoiding position displacement of the cardboard during the process of being transported from the feeding mechanism to the line pressing machine.

[0040] Among them, the interior of the lower fixed seat 3 has two symmetrical cavities for the installation of small motors 28, and the output shaft of each small motor 28 is fixedly sleeved with a first pulley 29, and each first pulley 29 is transmission-connected to the second pulley 31 through a synchronous belt 30. The second pulley 31 is fixedly installed on the front end outside of the cleaning roller 16, and the top of each of the cavities is provided with a makeshift groove for the synchronous belt 30 to pass through. By setting the small motor 28, the driving effect of the first pulley 29 is started, and the first pulley 29 will drive the second pulley 31 to rotate through the synchronous belt 30. When the synchronous belt 30 is driven to rotate, the cleaning roller rotates. During the rotation of the cleaning roller, the dust and paper scraps attached to the surface of the anti-slip pad 7 on the surface of the conveyor belt will be cleaned by the brush head 17. The cleaned dust and paper scraps will be collected into the dust storage bag 11 through the dust collecting hood 18.
