The leather passes around the upper side of the third conveying roller 7, the lower side of the second conveying roller 6 and the upper side of the first conveying roller 5 in turn, and then is sent out from the opening 4, and fixing components 8 are arranged on both sides of the inner rear end surface of the drying table 1, and the fixing components 8 are located directly behind the heating box body 2. The fixing components 8 on both sides respectively press and limit the two ends of the leather.
[0020] See also Figure 2 As shown, the rear end face of the heating box body 2 is penetrated with a plurality of evenly distributed hot air outlet holes 9, the bottom face of the heating box body 2 is penetrated with a plurality of preheating holes 10, the diameter and number of the preheating holes 10 are both smaller than the diameter and number of the hot air outlet holes 9, and the side end of the heating box body 2 is provided with a hot air pump 11 for injecting hot air into the heating box body 2.
[0021] See also Figure 4 As shown, the fixing assembly 8 includes a mounting seat 12, a connecting plate 13 and a plurality of rollers 14. The outer end of the mounting seat 12 is fixedly connected to the inner rear end surface of the drying table 1. The connecting plate 13 is arranged at the bottom of the mounting seat 12.

[0022] The working principle of this embodiment is as follows:
[0023] The leather is driven and conveyed by the first conveying roller 5, the second conveying roller 6 and the third conveying roller 7, and due to the setting of the second conveying roller 6, the leather is in a vertical state after passing through the second conveying roller 6, so that the leather is in an unfolded and straightened state by utilizing its own gravity. During the drying and shaping process, high-temperature hot air is injected into the heating box body 2 through the hot air pump 11, and then the hot air is ejected from the hot air outlet 9 and the preheating hole 10. When the leather first passes under the heating box body 2, it will receive a small amount of hot air ejected from the preheating hole 10 for preheating, so as to prevent the leather from being exposed to a large amount of hot air in a short time and causing instantaneous temperature rise, causing cracking and aging. Then, after passing through the second conveying roller 6, the left and right ends of the leather are pressed down and limited by the roller 14. The setting of the roller 14 does not affect the vertical conveying of the leather, but the convex strip thereon can effectively clamp the edge of the leather to prevent it from shrinking laterally due to heat. Then, the hot air ejected from the hot air outlet 9 is blown to the surface of the leather, so that it is heated and dried evenly to complete the shaping operation.
[0024] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
