[0006] In the present application, a new leather ironing machine is provided, comprising an ironing machine body, characterized in that a horizontal scraper is provided on the casing of the ironing machine body, the scraper extending from the casing to the conveyor belt in the ironing machine body, and being used to contact the conveyor belt from the outside of the conveyor belt, and scraping off impurities adhered to the outside of the conveyor belt as the conveyor belt runs; a negative pressure channel, the negative pressure channel being fixed on the casing, having one end connected to the front side of the scraper, and the other end connected to the negative pressure system, and being used to absorb the impurities scraped off by the scraper.

[0007] In one embodiment, the scraper is slidably connected to the housing in a direction approaching or moving away from the conveyor belt, so that the position of the scraper is adjustable.

[0008] In one embodiment, a guide rod is fixedly provided on the casing along the sliding direction of the scraper, and the scraper is slidably connected to the guide rod. A threaded column is rotatably provided on the side of the scraper away from the conveyor belt, and its central axis is parallel to the sliding direction of the scraper. The threaded column is threadedly connected to the casing, and the position of the scraper is adjusted by rotating the threaded column.

[0009] In one embodiment, the side of the scraper close to the conveyor belt is inclined toward the conveyor belt.

[0010] In one embodiment, the cross section of the scraper at one end close to the conveyor belt is triangular.

[0011] In one embodiment, the scraper is arranged at the rear side of the housing for contacting the vertical portion of the conveyor belt.

[0012] In summary, in this application, a new leather ironing machine has the following beneficial effects compared to the prior art: when the outer side of the conveyor belt (the side used to contact the leather) passes through the scraper, the dust, dandruff and other impurities attached to it will be scraped off by the scraper and then sucked away by the negative pressure channel, so that the conveyor belt is cleaned before it contacts the leather, avoiding impurities being pressed on the leather or even pressed into the leather during the ironing process, thereby improving the processing quality of the leather.

[0020] See also Figure 1 、 Figure 2 、 Figure 3 A new leather ironing machine includes an ironing machine body, which includes a casing 9, a rotating shaft 2 installed in the casing 9, and a heating roller 3 sleeved on the rotating shaft 2. The heating roller 3 is circumferentially provided with a clamping assembly, which includes an upper pressure roller 4, a lower pressure roller 5, an upper fixed roller 6, a lower fixed roller 7, and a conveyor belt 8. The upper pressure roller 4 is installed on the side wall of the casing 9 and can rotate relative to the side wall of the casing 9, and the lower pressure roller 5 is in contact with the heating roller 3; the upper fixed roller 6 is installed on the side wall of the casing 9 and is arranged relative to the upper pressure roller 4, and the upper fixed roller 6 and the upper pressure roller 4 are on the same horizontal line; the lower fixed roller 7 is installed on the back plate of the casing 9 and can rotate relative to the casing 9, and the lower fixed roller 7 and the upper fixed roller 6 are on the same vertical horizontal line; the lower pressure roller 5 is installed on the side wall of the casing 9 and is in contact with the heating roller 3, and the horizontal height of the lower pressure roller 5 is higher than the height of the lower pressure roller 5; the conveyor belt 8 is wrapped around the outside of the upper pressure roller 4, the upper fixed roller 6, the lower fixed roller 7, and the lower pressure roller 5, and the material is put in between the upper pressure roller 4 and the heating roller 3, transported by the conveyor belt 8, and output from the lower pressure roller 5.

[0021] See also Figure 1 、 Figure 3A horizontal scraper 12 is provided on the casing 9 of the ironing machine body. The scraper 12 extends from the casing 9 to the conveyor belt 8 in the ironing machine body, and is used to contact the conveyor belt 8 from the outside of the conveyor belt 8. As the conveyor belt 8 runs, the impurities adhered to the outside of the conveyor belt 8 are scraped off, and the left and right ends of the scraper 12 can extend out of the left and right sides of the conveyor belt 8 respectively.

[0022] See also Figure 1 、 Figure 3 , further comprising a negative pressure channel 16, which is fixed to the housing 9. One end of the negative pressure channel 16 is connected to the front side of the scraper 12 (the side from which the conveyor belt 8 comes), and the other end is connected to the negative pressure system 17, which is used to absorb impurities scraped off by the scraper 12. The negative pressure channel 16 is in a narrow rectangular shape, with its left and right sides extending to the left and right ends of the scraper 12. The negative pressure system 17 is mainly provided with suction by a negative pressure fan. Its specific structure is conventional and will not be described in detail here.

[0023] See also Figure 3 In one embodiment, the scraper 12 is slidably connected to the housing 9 in a direction toward or away from the conveyor belt 8, so that the position of the scraper 12 is adjustable. This arrangement allows the scraper 12 to be slid closer to the conveyor belt 8, thereby improving the scraping effect as needed, which is more flexible.

[0024] See also Figure 3 In one embodiment, a guide rod 10 is fixedly mounted on the housing 9 along the sliding direction of the scraper 12. The guide rod 10 is welded to the housing 9. The scraper 12 is provided with a through hole along its sliding direction and is slidably connected to the guide rod 10 through the through hole. A threaded post 13 is rotatably mounted on the side of the scraper 12 away from the conveyor belt 8, with its central axis parallel to the sliding direction of the scraper 12. A threaded hole is provided through the housing 9, and the threaded post 13 is threadedly connected to the threaded hole in the housing 9. The position of the scraper 12 can be adjusted by rotating the threaded post 13. This arrangement is simple to operate and has a relatively stable effect.

[0025] See also Figure 3 In one embodiment, the scraper 12 is arranged on the rear side of the casing 9 to contact the vertical portion of the conveyor belt 8. This arrangement is because the vertical portion of the conveyor belt 8 will move upward, and the scraper 12 is arranged here to scrape impurities on the conveyor belt 8 downward, resulting in a better scraping effect.

[0026] See also Figure 3In one embodiment, the side of the scraper 12 near the conveyor belt 8 is inclined (downward) toward the conveyor belt 8. This arrangement makes it easier to lift impurities adhering to the conveyor belt 8. Furthermore, the cross-section of the end of the scraper 12 near the conveyor belt 8 is triangular. This arrangement allows the scraper 12 to contact the conveyor belt 8 through the sharp corner to scrape off impurities, achieving a better effect.
