Technical Field

[0001] The utility model relates to the technical field of conveyor belt cleaning, in particular to a conveyor belt cleaner. Background Art

[0002] After the conveying equipment (conveyor belt) unloads, some materials will remain on the belt. The materials will continue to run with the belt and damage the belt, rollers, rollers and other components, which need to be cleaned. The existing cleaning device has a complex structure, and it is inconvenient to replace the scraper after it is worn, resulting in high cost of use. In addition, the existing cleaning device is difficult to retract and deform when encountering harder objects on the belt, causing the scraper to easily collide with the hard objects and be damaged. Therefore, in view of the above situation, there is an urgent need to develop a conveyor cleaner with a simple structure, easy processing, and convenient scraper replacement, which can reduce the time of downtime for scraper replacement and help improve corporate efficiency. When encountering harder adhesive materials on the conveyor belt, the scraper can reverse and retract the compression spring to avoid scraper damage and deformation of the entire machine, so as to overcome the shortcomings in current practical applications and meet current needs.

[0034] Working principle: When using the conveyor sweeper:

[0035] 1. First, pre-drill holes at the corresponding installation position and weld the corresponding supports. Install the entire machine at the corresponding position. The installation position should be calculated so that the scraper 210 extends 12-20mm relative to the upper surface of the guide plate 102. At this time, the scraper 210 is in contact with the tape to ensure the bending strength of the scraper 210.

[0036] 2. Rotate the handwheel 203 clockwise, and the spring seat 204 moves inward of the rectangular steel tube 101. One end of the spring 205 is compressed by the spring seat 204, and the other end of the spring 205 pushes the pulley frame 206 to move inward. The pulley frame 206 drives the pulley 208 to move. Since the knife holder 209 is tangent to the wheel groove of the pulley 208, as the pulley 208 moves inward, the knife holder 209 drives the scraper 210 to extend and press the tape tightly.

[0037] 3. As the scraper 210 and the tape are continuously worn, the compressed elastic potential energy of the spring 205 is released, pushing the pulley frame 206 to continue to move inward, and the pulley frame 206 drives the pulley 208 to continue to move inward. Since the blade holder 209 is tangent to the wheel groove of the pulley 208, as the pulley 208 moves inward, the blade holder 209 drives the scraper 210 to continue to extend and contact the tape surface;

[0038] 4. When the cleaning effect decreases, repeat steps 2-3. When the blade holder 209 contacts the limit pin 3, it means that the scraper 210 is worn out and needs to be replaced.

[0039] 5. Release the fixation of the whole machine, rotate the rectangular steel pipe 101, turn the whole machine to a position where it does not interfere with the tape, and pull out the worn scraper 210;

[0040] 6. Rotate the handwheel 203 counterclockwise, and the spring seat 204 moves toward the end of the rectangular steel tube 101. The elastic potential energy of the spring 205 is released. Due to the deadweight of the tool holder 209, the pulley holder 206 moves toward the end, and the tool holder 209 retracts.

[0041] 7. Insert the new scraper 210, rotate the rectangular steel pipe 101, and adjust the entire machine to the working position;

[0042] 8. Repeat steps 2-7.

[0043] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
