[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Embodiments of this utility model: such as Figures 1-3 As shown, a cleaning device for the pressure roller of a stem pressing machine includes a stem pressing machine frame 1, a pressure roller 2 rotatably mounted on the stem pressing machine frame 1, a bracket 3 fixedly mounted on the left and right sides of the stem pressing machine frame 1, a lever 4 rotatably mounted on each of the two brackets 3, a scraper 5 located at the bottom of the pressure roller 2, and the two ends of the scraper 5 fixedly connected to one end of each of the two levers 4, and the other ends of the two levers 4 are respectively provided with counterweight components.

[0020] By setting two supports 3 on the frame 1 of the pressing machine, and using the lever 4 on the support 3, a downward pulling force is applied to one end of the lever 4 by the counterweight component, so that the scraper 5 at the other end of the lever 4 is in close contact with the pressure roller 2, thereby enabling the scraper 5 to effectively clean the surface of the pressure roller 2.

[0021] Specifically, the frame 1 of the pressing machine includes a first support leg 11, a second support leg 12, an upper beam 13, a first side beam 14, and a second side beam 15. The two ends of the upper beam 13 are fixedly connected to the top ends of the first support leg 11 and the second support leg 12. The first side beam 14 and the second side beam 15 are arranged in parallel. One end of the first side beam 14 is fixedly connected to the upper end of the first support leg 11, and one end of the second side beam 15 is fixedly connected to the upper end of the second support leg 12. A first triangular support plate 16 is provided between the first support leg 11 and the first side beam 14, and a second triangular support plate 17 is provided between the second support leg 12 and the second side beam 15.

[0022] It should be noted that the pressing machine frame 1 and pressing roller 2 in this embodiment are existing equipment. Since the pressing machine frame 1 is very large, only a part of the pressing machine frame 1 is shown in the figure.

[0023] The two supports 3 have the same structure. One support 3 is fixedly connected to the upper beam 13 and the first triangular support plate 16, and the other support 3 is fixedly connected to the upper beam 13 and the second triangular support plate 17.

[0024] Furthermore, the support 3 includes a horizontal plate 31, an inclined plate 32, and a side plate 33. The horizontal plate 31 is fixedly connected to the upper end of the inclined plate 32, and the side plate 33 is fixedly mounted on one side of the inclined plate 32. A rectangular through hole 34 is provided on the inclined plate 32. Two bearing seats 35 are fixedly mounted on the side of the inclined plate 32 facing the pressure roller 2. The two bearing seats 35 are arranged opposite to each other on both sides of the rectangular through hole 34. The lever 4 passes through the rectangular through hole 34 and is rotatably connected to the two bearing seats 35 through the rotating shaft 36.

[0025] The horizontal plate 31 is fixed to the bottom surface of the upper beam 13 by bolt assembly. The side plate 33 on the left side bracket 3 is fixedly connected to the first triangular support plate 16 by bolt assembly. The side plate 33 on the right side bracket 3 is fixedly connected to the second triangular support plate 17 by bolt assembly.

[0026] The inclined plate 32 is inclined to the side where the pressure roller 2 is located. The main function of the inclined plate 32 is to install the lever 4. Preferably, the rotating shaft 36 is located on the lever 4 near the end of the scraper 5, so that the lever arm on one side of the counterweight assembly is greater than the lever arm on the other side, so that the scraper 5 can better abut against the bottom of the pressure roller 2.

[0027] Furthermore, the counterweight assembly includes a cylindrical counterweight block 6, the top of which is provided with a lifting ring mounting boss 61, a through hole is provided on the lifting ring mounting boss 61, a lifting ring 62 is installed on the lifting ring mounting boss 61, and a lifting ring mounting groove 41 is provided at the end of the lever 4 away from the scraper 5, and the lifting ring 62 is hung on the end of the lever 4 through the lifting ring mounting groove 41.

[0028] The cylindrical counterweight 6 is roughly aligned with the first support leg 11 and the second support leg 12. This allows the first support leg 11 and the second support leg 12 to act as a shield for the cylindrical counterweight 6, preventing workers from colliding with the cylindrical counterweight 6 and getting injured.

[0029] The lifting ring mounting groove 41 is an L-shaped groove, which can effectively prevent the lifting ring 62 from falling off the lever 4.

[0030] Furthermore, a counterweight lifting device 7 is provided between the first support leg 11 and the second support leg 12. The counterweight lifting device 7 includes a slide rail 71, a drive motor 72, a support plate 73, and a lead screw 74. A slide rail 71 is fixedly provided on the opposite surfaces of the first support leg 11 and the second support leg 12. The slide rail 71 is arranged vertically, and a slider 75 is slidably installed on each slide rail 71. The support plate 73 is arranged horizontally, and its two ends are fixedly connected to the two sliders 75 respectively. A support beam 18 is fixedly provided at the lower part between the first support leg 11 and the second support leg 12. The drive motor 72 is fixedly located in the middle of the top surface of the support beam 18. The lower end of the lead screw 74 is fixedly connected to the output shaft of the drive motor 72. A threaded hole 76 is provided in the middle of the support plate 73, and the lead screw 74 is threadedly connected to the threaded hole 76 on the support plate 73.

[0031] Because the two cylindrical counterweights 6 are quite heavy, when workers need to repair or maintain the scraper 5, they need to remove the scraper 5. Before removing the scraper 5, they need to remove the two cylindrical counterweights 6. It is difficult for one worker to remove the cylindrical counterweights 6, and it is very dangerous for two workers to operate them, as it is easy to cause accidents that could injure workers.

[0032] In this embodiment, by setting up a drive motor 72 and a support plate 73, when repairing or maintaining the scraper 5, the drive motor 72 is started. The output shaft of the drive motor 72 rotates the lead screw 74, which engages with the threaded hole 76 on the support plate 73, causing the support plate 73 to move horizontally upward. The cooperation between the slider 75 and the slide rail 71 prevents the support plate 73 from tilting. The support plate 73 lifts the two cylindrical counterweights 6. At this time, the end of the lever 4 is not under downward pressure, and the end where the scraper 5 is located will descend, facilitating the disassembly of the scraper 5 and making it easier to repair and maintain. After the scraper 5 is repaired or maintained, the drive motor 72 is controlled to rotate in the opposite direction, causing the support plate 73 to move downward, separating the support plate 73 from the two cylindrical counterweights 6. This not only reduces the workload but also eliminates safety hazards. It should be noted that the slider 75 and the slide rail 71 are commercially available products that can be purchased directly. The slider 75 can only move vertically along the slide rail 71 and will not detach from the slide rail 71.

[0033] Preferably, a U-shaped bracket 19 is also provided on the top of the supporting beam 18. The U-shaped bracket 19 is arranged with its opening facing downwards. The drive motor 72 is located inside the U-shaped bracket 19. A circular through hole is provided on the top plate of the U-shaped bracket 19, and the output shaft of the drive motor 72 passes through the circular through hole.

[0034] The U-shaped bracket 19 serves two purposes: firstly, it protects the drive motor 72, and secondly, it limits the output shaft of the drive motor 72, ensuring that the output shaft of the drive motor 72 and the lead screw 74 remain vertical.

[0035] Furthermore, a guide hole 77 is provided at each end of the support plate 73, and a guide rod 63 is fixed at the bottom of the cylindrical counterweight 6, with the guide rod 63 being inserted into the guide hole 77.

[0036] The guide rod 63, when inserted into the guide hole 77, serves a safety function. If the lifting ring 62 breaks, the cylindrical counterweight 6 will fall rapidly. Without the guide rod 63, the cylindrical counterweight 6 would not fall accurately onto the support plate 73 but would fall to the ground, potentially causing an accident if workers are nearby. By using the guide rod 63 and guide hole 77, when the lifting ring 62 fails and the cylindrical counterweight 6 falls, the guide rod 63 ensures that the cylindrical counterweight 6 lands stably on the support plate 73, preventing it from falling off and improving safety. It should be noted that because the movement trajectory of the cylindrical counterweight 6 is not a straight downward line when the lever 4 rotates around the pivot 36, the diameter of the guide hole 77 should be slightly larger than the diameter of the guide rod 63 to ensure that the guide rod 63 does not jam against the guide hole 77 during movement. During normal operation of the equipment, the pallet 73 should be located below the cylindrical counterweight 6, but it is necessary to ensure that the lower end of the guide rod 63 is always inserted into the guide hole 77.

[0037] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
