[0031] As Figure 1 and Figure 2 shown in the figure, it further includes scale lines 1901. The scale lines 1901 are provided on the guide rods 19.
[0032] When the leather needs to be ironed and polished, this equipment can be used. First, through the control box 3, the first motor 8 and the second motor 12 on the placement plate 11 start to work, so that the heating shaft 16 heats the ironing and polishing shaft 14. When the heating shaft 16 heats the ironing and polishing shaft 14 to a certain temperature, the leather can be ironed and polished. The leather to be ironed and polished is spread out on the first conveyor belt 10. The first motor 8 drives the first rotating shaft 9 to rotate, so that the first conveyor belt 10 starts to drive. When the leather on the first conveyor belt 10 contacts the elastic scraper 7 on the lifting plate 6, the elastic scraper 7 will scrape the wrinkles on the leather flat. The leather whose wrinkles are scraped flat by the elastic scraper 7 enters the limit frame 601 under the transmission of the first conveyor belt 10 and contacts the ironing and polishing shaft 14. The ironing and polishing shaft 14 slowly rotates under the drive of the second motor 12 and the second rotating shaft 13. The ironing and polishing shaft 14 heated by the heating shaft 16 irons and polishes the leather. The leather after ironing and polishing treatment leaves the limit frame 601 under the transmission of the first conveyor belt 10. During this process, the ironed and polished leather contacts the pressing wheel 604 at the rear side of the limit frame 601, and the pressing wheel 604 presses the leather. During this process, when the thickness of the leather is uneven, the pressing wheel 604 will drive the pressing block 603 to be lifted in the limit frame 601 by the part with a larger thickness of the leather. At this time, the spring 602 is compressed, so as to generate a greater extrusion force on the leather to ensure the uniformity of leather ironing and polishing. After passing through the pressing wheel 604, the ironed and polished leather is transmitted to the second conveyor belt 101 by the first conveyor belt 10, and the spring 602 resets, and the leather on the second conveyor belt 101 can be collected.
[0033] When the average thickness of the leather to be calendered is relatively large, it is necessary to adjust the height of the calender shaft 14 through the third motor 17, etc. First, start the third motor 17, and the third motor 17 drives the threaded rod 18 to rotate. During the rotation of the threaded rod 18, the lifting plate 6 rises on the threaded rod 18 and the guide rod 19. During the rising process of the lifting plate 6, observe the height to be adjusted through the scale line 1901 on the guide rod 19. During the rising process of the lifting plate 6, drive components such as the limit frame 601, the second motor 12, the second rotating shaft 13, and the calender shaft 14 to rise together. After adjusting the distance between the calender shaft 14 and the first conveyor belt 10, stop the third motor 17, and then repeat the above operation to calender the leather.
[0034] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
