Description

Cleaning hair roller brush for belt conveyor

technical field

The utility model belongs to the cleaning field of belt conveyors, in particular to a cleaning roller brush for belt conveyors.

Background technique

At present, the existing roller brush is only set on the belt, and by rotating and rolling, the bristles on the roller brush are used to clean the sundries or dust on the belt. Because the application environment of the belt conveyor is relatively harsh, it often encounters In rainy and snowy weather and dry weather, in rainy and snowy weather, the material sticking to the belt is often caused by rain and snow. When passing through the roller brush, on the one hand, the roller brush will transfer the muddy residual material with the rotation of the roller brush. And splash, and will leave similar mud marks on the belt. In dry weather, the material remaining on the belt will cause a lot of dust due to the rotation of the roller brush, and because the roller brush only rotates fixedly, it will be on the belt. Directional gray marks form on the belt and the belt cannot be cleaned cleanly.

Among them, there are two dryers for drying the belt up and down, and there are two roller brushes, including the upper roller brush and the lower roller brush. The hair roller brush has the same structure and is driven by a motor to rotate.

The hair roller brush includes bristles and a rotating roller; wherein, a plurality of grooves arranged along the axial direction of the rotating roller are arranged on the outer periphery of the rotating roller, and brush blocks are arranged in the grooves, and the brush blocks can move along the direction of the rotating roller in the grooves. Sliding back and forth in the length direction of the brush block, in order to limit the sliding stroke of the brush block, one end of the groove is penetrated through the roller, and the other end is not penetrated and is provided with a side wall; one end of the brush block is connected with a guide wheel through a connecting rod, and the brush block The other end is connected with a spring, and the spring is connected on the side wall in the groove.

The upper surface of the brush block is also provided with bristles. In order to absorb dust, it is also provided with air suction holes and air suction chambers. The lower part of the groove is provided with a suction chamber, which communicates with all the suction holes; in order to realize the suction of dust from the brush, a negative pressure chamber is also provided at the bottom of the groove, and the negative pressure chamber is provided with a negative pressure port , wherein, the suction cavity communicates with the negative pressure cavity, and the length of the suction cavity is greater than the length of the negative pressure cavity, and the width of the negative pressure cavity is greater than the width of the negative pressure cavity, so that the brush block sucks air when sliding along the groove The chamber and the vacuum chamber are always at least partially in communication.

One side of each hair roller brush is also correspondingly provided with a guide wall, and a circular guide groove is arranged in the guide wall. The guide groove moves, and the raised section is set directly below or directly above the guide groove, and the raised section is a section of raised guide rail, so that during the rotation of the roller brush, the brush block moves on the smooth section of the guide groove When the brush block rotates with the roller brush, when the brush block rotates to the raised section with the roller brush, that is, when the brush block cleans the belt, the protrusion of the raised section The guide rail pushes the guide wheel to move in the direction of the spring, so that the spring is compressed and then drives the brush block to clean the belt along the width direction of the belt at the same time of rotation, so as to realize circumferential and horizontal cleaning. When the brush block does not pass through the raised section, that is, when the belt is not being cleaned, the brush block returns to the initial state under the restoring force of the spring, and only rotates with the hair roller brush.

In order to realize the suction of dust during the cleaning process, at least two sections of arc-shaped fixed negative pressure holes are arranged on the guide wall, at least one fixed negative pressure hole is set above or below the track of the raised section, and the fixed negative pressure holes are connected To the negative pressure dust collection system, and connected with the negative pressure port of the negative pressure chamber, it is used to absorb the dust generated during cleaning; When the fixed negative pressure hole is located at other positions on the guide wall, the fixed negative pressure hole is connected with the negative pressure port of the negative pressure chamber for absorbing the dust remaining on the bristles.

For the upper hair roller brush, the raised section in the corresponding guide wall is set at the position directly below the guide groove, that is, the bottommost position, and at least one section of fixed negative pressure hole is arranged at the raised section of the guide groove. directly above.

For the lower hair roller brush, the raised section in its corresponding guide wall is arranged at the position directly above the guide groove, that is, the highest end position, and at least one section of fixed negative pressure hole is arranged on the front of the raised section of the guide groove. lower position.

Adopting the above-mentioned technical scheme, the main utility model point of the utility model is: it is provided with a brush block in the hair roller brush, and the brush block can be rotated and cleaned when cleaning the belt under the guidance of the guide wheel and the spring. , and suck away the generated dust, and clean the dust generated during cleaning and the remaining dust after cleaning through the negative pressure hole on the guide wall.

The utility model at least includes the following beneficial effects:

1. With the setting of the scraper, the larger residue can be removed first;

2. The dryer with upper and lower structures can ensure the cleaning of wet objects in rainy and snowy weather and transport, avoiding wet dust adhering to the belt and difficult to clean thoroughly and adhering to the bristles;

3. By arranging multiple brush blocks, when the belt is rotated and cleaned, it can be cleaned while rotating and cleaning along the width direction of the belt, which improves the cleaning effect, and by setting the suction holes on the brush blocks, It can effectively absorb the dust generated when the brush block cleans the belt and absorb the dust on the roller brush around the brush block, so as to avoid dust overflow and pollute the environment.
