[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Please refer to Figure 1 — Figure 7 ,in, Figure 1 A schematic diagram of the overall structure of the transmission roller surface cleaning device provided by the present invention; Figure 2 A schematic structural diagram of a cleaning roller of a drive roller surface cleaning device provided by the present invention; Figure 3 A schematic diagram of the mounting structure of the transmission roller surface cleaning device provided by the present invention; Figure 4 Schematic diagram of the cross-sectional structure of the mounting frame of the drive roller surface cleaning device provided by the present invention Figure 1 ; Figure 5 Schematic diagram of the cross-sectional structure of the mounting frame of the drive roller surface cleaning device provided by the present invention Figure 2 ; Figure 6 for Figure 4 The enlarged view of point a is shown; Figure 7 This is a schematic cross-sectional view of the overall structure of the transmission roller surface cleaning device provided by the present invention.

[0029] In the specific implementation process, a transmission roller surface cleaning device, the structure of which is as follows Figure 1 — Figure 7 As shown, it includes: a mounting frame 1, two plug-in slots 14 are provided on the inner side wall of the mounting frame 1, a scraper 2 is inserted between the two plug-in slots 14, a driving component 3 for adjusting the scraper 2 is slidably connected in the plug-in slot 14, an elastic member 4 is slidably connected to the top wall of the two plug-in slots 14, the lower end surface of the elastic member 4 is fitted to the upper end surface of the driving component 3, a limiting rod 5 for supporting the scraper 2 is inserted between the two plug-in slots 14, a driving component 2 6 for adjusting the limiting rod 5 is inserted in the plug-in slot 14, a cleaning roller 7 is slidably connected to the outer side wall of the mounting frame 1, and a collecting tank 8 is rotatably connected to the bottom end of the mounting frame 1;

[0030] It should be noted that the mounting frame 1 is in an L-shape as a whole. The mounting frame 1 is installed on the side of the silicon steel unit adjacent to the transmission roller. A through groove 9 for inserting the scraper 2 is opened on the lower end surface of the mounting frame 1 adjacent to the transmission roller. The scraper 2 is inserted into the insertion groove 14 through the through groove 9.

[0031] The silicon steel unit includes a drive roller, a steering roller and a tension roller. The mounting frame 1 is threadedly connected to the steering roller and the tension roller base. The drive roller is tangent to the scraper 2.

[0032] Both sides of the mounting frame 1 are integrally connected with extension rods 11, and the two extension rods 11 are rotatably connected to the silicon steel unit through a rotating shaft. Sleeves 12 are embedded outside the extension rods 11, and the bottom ends of the sleeves 12 are fixedly connected to connecting plates 13. The bottom ends of the two connecting plates 13 are welded to the upper end surface of the collecting tank 8. When the tension roller and the steering roller need to be inspected and maintained, the tension roller and the steering roller can be exposed by rotating the mounting frame 1, so that the tension roller and the steering roller can be maintained;

[0033] When cleaning the transmission roller, first adjust the distance between the scraper 2 and the transmission roller through the drive component 1 3 so that the scraper 2 fits just against the side wall of the transmission roller, and then adjust the drive component 2 6 so that the limit rod 5 moves below the scraper 2, so that the limit rod 5 limits the scraper 2 to prevent the scraper 2 from moving freely under the action of the transmission roller. When cleaning the transmission roller, first, under the rotation of the transmission roller, the transmission roller applies a force along the tangential direction of the transmission roller and perpendicular to the surface of the scraper 2 on the scraper 2. At this time, foreign matter on the surface of the transmission roller will be scraped off by the scraper 2. At this time, the scraped debris will fall into the collection groove 8 at the bottom end of the mounting frame 1, thereby collecting the debris and avoiding pollution. At the same time, by adjusting the position of the cleaning roller 7 so that the cleaning roller 7 is close to the transmission roller, the cleaning roller 7 will clean the dust and sludge adhered to the side wall of the transmission roller, thereby scraping off the foreign matter. The scraped foreign matter, dust and sludge will fall into the collection groove 8 rotatably connected to the bottom end of the mounting frame 1.

[0034] The drive assembly 3 includes a threaded screw 31, one end of which passes through the outer wall of the mounting frame 1, and the other end of the threaded screw 31 is rotatably connected to the side wall of the insertion slot 14. The threaded screw 31 is externally threadedly connected to a slider 32, and the end of the threaded screw 31 away from the slider 32 is welded to a driving member. The drive assembly 3 also includes a guide rod 34, which is welded to another insertion slot 14 arranged opposite to the threaded screw 31.

[0035] It should be noted that the top of the two sliders 32 are provided with a horseshoe-shaped groove 35. Under the limit of the two horseshoe-shaped grooves 35, the scraper 2 will follow the two sliders 32 to move synchronously. At the same time, the horseshoe-shaped grooves 35 facilitate the removal or installation of the scraper 2.

[0036] When adjusting the scraper 2, first turn the knob 33, which drives the threaded screw 31 to rotate, and the threaded screw 31 drives the two sliders to slide along the threaded screw 31 and the guide rod 34 respectively, so that the scraper 2 slides toward the transmission roller under the drive of the two sliders 32, so that the scraper 2 fits against the side wall of the transmission roller, thereby removing the debris adhering to the side wall of the transmission roller.

[0037] The elastic member 4 includes a sliding plate 41, a sliding groove 15 is opened on the top wall of the plug-in slot 14, the sliding plate 41 is slidably connected to the sliding groove 15, a plurality of fixed columns 42 are welded in the sliding groove 15, a plurality of fixed columns 42 pass through the sliding plate 41, both ends of the plurality of fixed columns 42 are respectively welded to the inner cavity top wall and the inner cavity bottom wall of the sliding groove 15, a spring 43 is nested outside the plurality of fixed columns 42, one end of the spring 43 is welded to the upper end surface of the sliding plate 41, and the other end of the spring 43 is fitted with the top wall of the sliding groove 15, and the lower end surface of the sliding plate 41 is fitted with the top wall of the slider 32, and the sliding plate 41 is rotatably connected to a rotating plate 44 at one end of the driving member, and the side wall of the rotating plate 44 is fitted with the top wall of the sliding groove 15. The side wall of the sliding plate 41 is integrally connected with a baffle 45 for limiting the rotating plate 44, and the length of the rotating plate 44 is equal to the height of the sliding groove 15;

[0038] It should be noted that by rotating the rotating plate 44, the rotating plate 44 is in a vertical state. At this time, the rotating plate 44 will limit the sliding plate 41, so that the sliding plate 41 is always in contact with the upper end surface of the slider 32, thereby keeping the horseshoe-shaped groove 35 in a sealed state, preventing the sliding plate 41 from moving freely and causing the scraper 2 to detach from the horseshoe-shaped groove 35, thereby limiting the scraper 2.

[0039] The driving assembly 2 6 includes a threaded screw 2 61 and a guide rod 2 62. One end of the threaded screw 2 61 is rotatably connected to the inner side wall of the plug-in slot 14 near the bottom end, and the threaded screw 2 61 is located below the threaded screw 1 31 and the guide rod 1 34. The other end of the threaded screw 2 61 passes through the side wall of the mounting frame 1, and the end of the threaded screw 2 61 away from the plug-in slot 14 is welded with a knob 2 63. The guide rod 2 62 is welded in the plug-in slot 14 opposite to the threaded screw 2 61. The external thread of the threaded screw 2 61 is connected to the slider 2 64. The external of the guide rod 2 62 is slidably connected to the slider 2 64. The limit rod 5 is inserted between the two sliders 2 64, and the limit rod 5 is located below the scraper 2.

[0040] It should be noted that, by rotating the second knob 63, the second knob 63 drives the second threaded screw 61 to rotate, and the second threaded screw 61 drives the second slider 64 to slide along the second threaded screw 61. Since the two ends of the limit rod 5 are welded to the two sliders, the two sliders 64 move synchronously under the action of the limit rod 5. Under the limiting action of the limit rod 5, when the transmission roller applies a downward force along the tangential direction of the side wall of the transmission roller to the scraper 2, the scraper 2 will remain relatively stationary under the support of the limit rod 5, so that the scraper 2 will apply a greater force to the debris adhering to the side wall of the transmission roller, thereby improving the efficiency of the scraper 2 in cleaning the transmission roller.

[0041] Since the two ends of the scraper 2 are respectively rotatably connected to the horseshoe-shaped grooves 35 of the two sliders 32, the scraper 2 can be adjusted according to the size of the transmission roller. By rotating the scraper 2, the scraper 2 is made tangent to the transmission roller, and then the limit rod 5 is adjusted to make the limit rod 5 fit with the lower end surface of the scraper 2, thereby limiting the scraper 2, increasing the force of debris acting on the scraper 2 that the scraper 2 can withstand, and thereby improving the scraper 2's efficiency in removing firmly adhered debris.

[0042] The cleaning roller 7 includes two movable plates 71, which are slidably connected to the two sides of the mounting frame 1 respectively. A brush roller 72 is rotatably connected between the two movable plates 71. A plurality of brushes 73 are fixedly connected to the side walls of the brush roller 72. An extrusion rod 74 is connected to the inner thread of the movable plate 71. The extrusion rod 74 is attached to the side wall of the mounting frame 1 at one end adjacent to the mounting frame 1.

[0043] Two slide bars 16 are integrally connected to both sides of the mounting frame 1. An extrusion rod 74 is inserted between the two slide bars 16. A flexible member is fixedly connected to one end of the extrusion rod 74 adjacent to the mounting frame 1. The flexible member includes a silicone block 75. The silicone block 75 is adhered to the side of the extrusion rod 74 adjacent to the mounting frame 1, and the side of the silicone block 75 away from the extrusion rod 74 is attached to the side wall of the mounting frame 1.

[0044] It should be noted that two receiving plates are integrally connected to the opposite sides of the two movable plates 71, and the two slide bars 16 are located between the two receiving plates. Under the limitation of the two receiving plates, the movable plate 71 can only slide back and forth along the direction of the slide bar 16. By rotating the extrusion rod 74, the extrusion rod 74 applies pressure to the silicone block 75, thereby increasing the pressure applied by the silicone block 75 on the side wall of the mounting frame 1, and then increasing the friction between the silicone block 75 and the side wall of the mounting frame 1, so as to install the two movable plates 71. When maintaining or replacing the brush roller 72, it is only necessary to rotate the two extrusion rods 74 in the opposite direction to reduce the friction between the silicone block 75 and the side wall of the mounting frame 1, so that the two movable plates 71 and the brush roller 72 can be removed along the slide bar 16, and the brush roller 72 can be maintained or replaced.

[0045] The scraper 2 includes a blade 21, and a plug-in rod 22 is integrally connected to the top of the blade 21. The two ends of the plug-in rod 22 are respectively inserted into the two plug-in grooves 14. The plug-in rod 22 is cylindrical, which is convenient for rotating the plug-in rod 22 in the horseshoe-shaped groove 35 to facilitate adjusting the angle between the scraper 2 and the side wall of the transmission roller.

[0046] The driving member includes a knob 33 , which is bonded to an end of the threaded screw 31 away from the scraper 2 .

[0047] The working principle of the present invention is as follows: first, the mounting frame 1 is installed on one side of the transmission roller in the silicon steel unit. When installing the mounting frame 1, the scraper 2 is first passed through the through slot 9 to make the connecting rod 22 enter the two connecting slots 14. Then, the rotating plate 44 is rotated, and an upward force is applied to the rotating plate 44 to lift the sliding plate 41. At this time, the connecting rod 22 can be inserted into the horseshoe-shaped groove 35. Then, the rotating plate 44 is loosened and rotated to a vertical state so that the side wall of the rotating plate 44 fits with the top wall of the sliding slot 15, thereby limiting the sliding plate 41. Then, the distance between the scraper 2 and the transmission roller is adjusted by turning the knob 1 33. When the scraper 2 is in a position where it can be tangent to the transmission roller, the knob 2 63 is turned. The knob 2 63 drives the limiting rod 5 to slide toward the scraper 2 through the slider 2 64. When the scraper 2 is rotated, the two movable plates 71 are inserted along the slide bar 16, and the two movable plates 71 are slid along the slide bar 16 to make the brushes 73 of the brush roller 72 fit the transmission roller. At this time, the squeezing rod 74 can be rotated, and the squeezing rod 74 squeezes the silicone block 75, increasing the friction between the silicone block 75 and the side wall of the mounting frame 1, thereby improving the installation strength of the movable plate 71 and the brush roller 72. Since the brush 73 is made of flexible material, the brush roller 72 is subjected to less force, and the two silicone blocks 75 can achieve the effect of preventing the movable plate 71 from moving freely, which is also convenient for installing and disassembling the brush roller 72. At the same time, the debris and dust removed by the brush roller 72 and the scraper 2 will fall into the collection tank 8.

[0048] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0049] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
