When this accumulates to a certain level, it can cause defects such as scratches and dents on the strip, reducing product yields, impacting production line efficiency, and increasing costs.

[0003] The currently common power-generating roller scrapers have some shortcomings: on the one hand, in terms of energy supply, many scraper devices require an external power supply to drive the work, which not only increases the complexity of the equipment layout, but may also be affected by the stability of the power supply. Once a power failure or instability occurs, it will affect the normal operation of the scraper, and thus affect the entire production process. On the other hand, for the replacement and maintenance operations of the scraper, the existing devices are often cumbersome. When the scraper is worn due to long-term use and needs to be replaced, the disassembly and installation process is complicated, which consumes a lot of time and manpower, reduces production efficiency and increases production costs. Therefore, a power-generating roller scraper is proposed to solve the above problems. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1-Figure 3 The utility model provides an embodiment: a power-generating roller scraper, including a base 1, a generator 2 is fixedly connected to the right side of the top of the base 1, and an air compressor 3 is fixedly connected to the left side of the top of the base 1. The generator 2 and the air compressor 3 are electrically connected. The generator 2 and the air compressor 3 are both existing technologies. The output shaft of the generator 2 rotates, so that the generator 2 can automatically generate electricity, and the air compressor 3 can be started by connecting the line, and the starting work of the generator 2 and the air compressor 3 will be detected by an external distribution cabinet. Two sets of air pipes 4 are provided on the outer wall of the air compressor 3, and the end of the air pipe 4 away from the air compressor 3 is fixedly connected to the left outer wall of the airbag seat 6. The air pressure generated by the air compressor 3 when it is working is transmitted to the airbag seat 6 through the air pipe 4, so that the connecting seat 7 can be controlled to drive the scraper 11 on its surface to open and close.

[0031] Reference Figure 2-Figure 3, two sets of brackets 5 are fixedly connected to the top of the outer wall of the base 1, and the outer wall of the top of the right bracket 5 is rotatably connected to the pulley B9. A driven pulley 10 is rotatably connected between the two sets of brackets 5. The outer wall of the driven pulley 10 contacts the outer wall of the active roller of the device, so that when the active roller of the device rotates, it drives the driven pulley 10 to rotate synchronously with it. The driven pulley 10 is fixedly connected to the rotation center axis of the pulley B9. The pulley B9 is connected to the pulley A8 through a belt drive. When the driven pulley 10 rotates, it drives the pulley B9 to rotate synchronously with it. The outer walls of the two sets of brackets 5 are fixedly connected to the airbag seat 6, and the inner wall of the airbag seat 6 is rotatably connected to the connecting seat 7. The outside of the airbag seat 6 is externally connected to the air pipe 4, so that the connecting seat 7 can be controlled to drive the scraper 11 to open and close. The output shaft of the generator 2 is fixedly connected to the pulley A8, and the inner wall of the connecting seat 7 is detachably installed with the scraper 11 through the quick-release assembly 12. The scraper 11 is slidably connected to the inner wall of the connecting seat 7.

[0032] Reference Figure 3-Figure 4 The quick-release assembly 12 includes a moving rod 124, and the moving rod 124 is provided with two groups. The two groups of moving rods 124 are elastically connected to the inner wall of the connecting seat 7 by a limit spring 121. One end of the limit spring 121 is fixedly connected to the outer wall of the moving rod 124, and the other end of the limit spring 121 is fixedly connected to the inner side wall of the connecting seat 7. The function of the limit spring 121 is to automatically reset the position of the moving rod 124 after being pushed to move. The inner wall of the connecting seat 7 is provided with a sliding groove that fits the moving rod 124, so that the moving rod 124 can only move horizontally. The positioning block 123 is slidably connected to the inner wall of the connecting seat 7, and the outer wall of the moving rod 124 is fixedly connected to the positioning block 123. When the moving rod 124 moves, it will push the positioning block 123 to move synchronously with it, and the inner wall at the center of the connecting seat 7 is slidably connected to the trapezoidal block 125.

[0033] Reference Figure 3-Figure 4 The end of the moving rod 124 away from the limit spring 121 is provided with a slide groove, and the two sides of the bottom end of the trapezoidal block 125 are slidably connected to the inner wall of the slide groove, and the bottom end of the trapezoidal block 125 is provided with a guide block that fits the slide groove of the moving rod 124, so that the trapezoidal block 125 will synchronously push the two sets of moving rods 124 towards each other or away from each other when moving up and down. The outer walls on both sides of the scraper 11 are provided with through holes 122, and the left outer wall of the positioning block 123 is provided with a protrusion, and the protrusion part of the positioning block 123 is plugged into the inner wall of the through hole 122. The plugging between the two fixes the scraper 11 in the position of the inner wall of the connecting seat 7, and also facilitates its quick disassembly and replacement.

[0034] Working principle: First, when the equipment is running, the active roller of the equipment drives the driven wheel 10 in contact with it to rotate, and the rotation of the driven wheel 10 drives the pulley B9 fixedly connected to it to rotate synchronously. Through the transmission of the belt, the pulley A8 follows the rotation, thereby driving the output shaft of the generator 2 to rotate to generate electricity. The electric energy generated by the generator 2 is transmitted through the connecting line to start the air compressor 3. The air pressure generated by the air compressor 3 is transmitted to the air bag seat 6 through the air pipe 4. The change of the air pressure in the air bag seat 6 controls the connecting seat 7 to drive the scraper 11 to open and close.

[0035] When the scraper 11 needs to be replaced, the quick-release assembly 12 is operated to push the trapezoidal block 125 downward. Due to the cooperation of the guide block at the bottom end of the trapezoidal block 125 and the sliding groove at the end of the moving rod 124, the descending of the trapezoidal block 125 will push the two sets of moving rods 124 to move outward synchronously, compressing the limit spring 121. While moving the moving rod 124, it drives the fixedly connected positioning block 123 to slide on the inner wall of the connecting seat 7, so that the protruding parts of the positioning block 123 are disengaged from the through holes 122 on the outer walls of both sides of the scraper 11, thereby releasing the fixation of the scraper 11. At this time, the scraper 11 can be taken out of the connecting seat 7 for replacement. When installing a new scraper 11, the scraper 11 is inserted into the connecting seat 7, and the trapezoidal block 125 is loosened. Under the action of the limit spring 121, the moving rod 124 is reset, driving the protruding parts of the positioning block 123 to insert into the through holes 122 on the outer walls of both sides of the scraper 11, and fixing the scraper 11 in the connecting seat 7.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
