Description

Technical Field

[0001] The utility model relates to a belt cleaning device, in particular to an automatic power roller brush cleaner. Background Art

[0002] Belt conveyors, also known as belt conveyors, are widely used in the transportation of materials in ports. During the belt transportation process and the belt production process, due to the influence of material viscosity, electrostatic adsorption, etc., powder materials will stick to the belt surface. If they are not cleaned in time, the belt conveyor will slip or deviate, seriously causing major accidents such as belt damage and tearing.

[0003] A common belt conveyor cleaner is to add a roller brush to the bottom of the belt conveyor for cleaning. However, the existing cleaner requires an additional external power supply to power the roller brush, has a relatively complex structure, and has a high failure rate. Moreover, with long-term cleaning, the roller brush will gradually create a gap between it and the belt due to wear, making it impossible to clean the belt surface well. The entire roller brush needs to be replaced, which is relatively costly. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an automatic powered roller brush cleaner, which effectively solves the problem that the existing cleaner needs an external power supply and the roller brush needs to be replaced frequently.

[0005] To achieve this technical purpose, the utility model adopts the following scheme:

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] The utility model adjusts the upper and lower positions of the cleaning roller by adjusting the upper and lower positions of the bearing seat one, thereby ensuring that the surface of the cleaning roller contacts the surface of the belt, thereby achieving the effect of cleaning the belt; the horizontal position of the bearing seat two is adjusted to adjust the relative position of the belt power roller and the cleaning roller, thereby playing the role of adjusting the tension of the transmission mechanism, preventing the transmission mechanism from idling, and ensuring the stable operation of the cleaning roller.

DETAILED DESCRIPTION

[0023] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.

[0024] like Figures 1 to 7 As shown, an automatic powered roller brush cleaner is composed of a support frame 2, a belt-powered roller 3 and a cleaning roller 4 which are arranged opposite to each other on both sides of a belt 1. The belt-powered roller 3 and the cleaning roller 4 are respectively installed between the two support frames 2, and the belt-powered roller 3 and the cleaning roller 4 are connected by a transmission mechanism. The cleaning roller 4 is connected to the support frame 2 through a bearing seat 1 8, and the belt-powered roller 3 is slidably connected to the support frame 2 through a bearing seat 2 11.

[0025] The top of the support frame 2 on each side is fixedly connected to the bearing seat 8, and two long holes 9 are provided on the side wall of the frame 21. The positions of the bearing seat 8 corresponding to the long holes 9 are respectively provided with mounting holes, and bolts 10 are provided in the mounting holes. The bolts 10 penetrate through the corresponding long holes 9 and are locked by nuts. In this embodiment, brushes are evenly provided on the surface of the cleaning drum 4. The height of the bearing seat 8 is adjusted according to the contact distance between the cleaning drum 4 and the surface of the belt 1, so that the brushes are slightly in contact with the surface of the belt 1, ensuring that the cleaning drum 4 is in contact with the surface of the belt 1.

[0026] The top of the support frame 2 on each side is also fixedly connected to a frame 22 corresponding to the bearing seat 2 11. The upper and lower side walls of the frame 22 are respectively provided with raised slideways 17 in the horizontal direction. The upper and lower surfaces of the bearing seat 2 11 are respectively provided with slide grooves 18 adapted to the slideways 17. The bearing seat 2 11 is slidably connected to the frame 22 through the cooperation of the slide grooves 18 and the slideways 17.

[0027] A limiting plate 15 is provided on the side wall of the frame 22 , a through hole is opened in the center of the limiting plate 15 , a fixing nut 16 is fixedly connected to the outer side of the limiting plate 15 at a position corresponding to the through hole, and the inner end of the screw rod 14 passes through the limiting plate 15 and is threadedly connected to the fixing nut 16 .

[0028] An ear seat 12 is installed on the side wall of the bearing seat 11, and the interior of the ear seat 12 is connected to one end of the fixed block 19 through a pin shaft 13, and the other end of the fixed block 19 is rotatably connected to the inner end of the screw 14 (the fixed block may be provided with a mounting groove, a bearing is installed in the mounting groove, and the inner end of the screw is rotatably connected to the mounting groove through the bearing).

[0029] In this embodiment, the transmission mechanism is composed of a driving pulley 5, a driven pulley 7 and a transmission belt 6. The driving pulley 5 is installed at one end of the central axis of the belt-powered drum 3, and the driven pulley 7 is installed at one end of the central axis of the cleaning drum 4. The driving pulley 5 and the driven pulley 9 are located on the same side of the belt 1, and the driving pulley 5 is connected to the driven pulley 7 through the transmission belt 6. In this embodiment, the transmission ratio of the driving pulley and the driven pulley is 1:2, so the rotation speed of the cleaning drum is twice that of the belt-powered drum, thereby improving the cleaning effect.

[0030] In this embodiment, the belt power roller 3 and the cleaning roller 4 are placed under the return belt, and the belt operation provides power for the belt power roller 3, and the belt power roller 3 rotates the cleaning roller 4 through the transmission mechanism, and the cleaning roller 4 cleans the surface of the belt 1. As the brush on the surface of the cleaning roller 4 wears, the brush cannot effectively contact the surface of the belt 1. At this time, the height of the bearing seat 8 at both ends of the cleaning roller 4 is adjusted so that the brush slightly contacts the surface of the belt 1, and the belt 1 continues to be cleaned.

[0031] Since the transmission belt 6 may become loose after the belt-powered roller 3 and the cleaning roller 4 have been running for a long time, rotating the screw 14 can make the bearing seat 11 slide along the slideway 17 in the horizontal direction, thereby adjusting the position of the bearing seat 11, thereby adjusting the distance between the belt-powered roller 3 and the cleaning roller 4, and finally adjusting the distance between the driving pulley 5 and the driven pulley 7 to ensure the tension of the transmission belt 6 and ensure that the belt-powered roller 3 can effectively drive the cleaning roller 4 to rotate.

[0032] In this device, the belt 1 provides power for the belt-powered roller 3, and the cleaning roller 4 cleans the belt surface through the transmission belt 6. The height of the cleaning roller 4 and the distance from the belt-powered roller 3 are adjusted by the movable bearing seat 1 8 and the bearing seat 2 11 to ensure that the cleaning roller 4 can work stably.

[0033] The utility model adjusts the distance between the belt power roller and the cleaning roller by adjusting the relative position of the bearing seat 2 in the frame 2, thereby adjusting the tension of the transmission belt, thereby making the belt power roller in close contact with the transmission belt, thereby ensuring the stable operation of the cleaning roller; through the different speed ratios between the driving pulley on the belt power roller and the driven pulley on the cleaning roller, a higher speed is provided for the cleaning roller, thereby improving the cleaning effect; the bearing seat 1 is installed in the frame 1, and the height of the cleaning roller can be adjusted according to the distance between the brush on the cleaning roller and the belt surface; the device is simple to operate and convenient to maintain during use, and does not require a complex motor reducer to provide power.

[0034] Finally, it should be noted that the above-listed examples are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and modifications fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
