[0024] It should be noted here that: through the setting of the drying mechanism, while adapting to the drying of geotextile bodies 103 of different widths, the adjustment mechanism is used to facilitate the adjustment of the size of the air outlet area according to the width of the geotextile body 103, and the air outlet 306 not opposite to the geotextile body 103 is closed, thereby increasing the hot air output of the air outlet 306 opposite to the geotextile body 103 while keeping the total amount of hot air unchanged, thereby improving the drying effect of the geotextile body 103 while achieving full utilization of the hot air.

[0025] It is worth noting that the width of the hot air drying oven can reach more than 6 meters.

[0026] See also Figure 4 and Figure 5 , the mounting rings 401 located on both sides of the geotextile body 103 shown in the figure are connected by a fixing plate 404;

[0027] It should be noted here that: the setting of the fixing plate 404 facilitates the synchronous movement of the multiple mounting rings 401 located on both sides of the geotextile body 103.

[0028] See also Figure 4 and Figure 5 The driving mechanism shown in the figure includes a first mounting plate 501 fixedly connected to the side walls of two mounting rings 401 symmetrically arranged on the same side, a driving rod 502 is rotatably connected between the two first mounting plates 501, and the side wall of the driving rod 502 is provided with two thread bars 503 arranged in opposite directions of thread rotation, the two first mounting plates 501 are respectively threadedly connected to the thread bars 503, one end of the driving rod 502 is arranged to penetrate the oven body 102, and is fixedly connected to a crank 504;

[0029] It should be noted here that: by setting the driving mechanism, it is convenient to drive the two relative mounting rings 401 to move closer to or away from each other.

[0030] See also Figure 4 and Figure 5 , the oven body 102 shown in the figure is provided with a guide assembly for guiding the movement of the mounting ring 401, the guide assembly includes a second mounting plate 601 fixedly connected to two side walls of the mounting ring 401 symmetrically arranged on the same side, the two second mounting plates 601 are symmetrically arranged with the first mounting plate 501, a guide rod 602 is slidably connected between the two second mounting plates 601, and both ends of the guide rod 602 are respectively connected to the inner wall of the oven body 102;

[0031] It should be noted here that: by setting the guide assembly, a guiding and limiting function is provided for the movement of the two relative mounting rings 401 .

[0032] Working principle: When drying the geotextile body 103, the geotextile body 103 processed from the geotextile processing production line 101 first enters the oven body 102 for drying, and under the winding action of the winding roller 2, the dried geotextile body 103 is rolled up, thereby realizing the continuity of the processing, drying and rolling processes of the geotextile body 103, and further improving the processing efficiency of the geotextile body 103;

[0033] When the geotextile body 103 is dried, the hot air blower 301 is started to deliver the hot air to the two air outlet pipes 305 through the connecting pipe 302, and finally blown to the two sides of the geotextile body 103 from the multiple air outlets 306, so that the geotextile body 103 is dried under the blowing action of the hot air;

[0034] Since the oven body 102 is adapted to the drying of geotextile bodies 103 of different widths, the width of the oven body 102 itself is relatively large. Therefore, in order to avoid the waste of hot air caused by the fact that some air outlets 306 are not opposite to the geotextile body 103, it is necessary to adjust the hot air outlet area. During the adjustment process, the driving rod 502 is driven to rotate by turning the crank 504. Since two threaded strips 503 with opposite thread rotation directions are provided on the side wall of the driving rod 502, during the rotation of the driving rod 502, the threaded strips 503 and the first mounting plate 501 are engaged with each other and the two relative mounting rings are driven under the guidance of the guide assembly. 401 move towards or away from each other, so that in the process of the two relative mounting rings 401 moving towards or away from each other, the telescopic protective tube 402 is stretched or contracted, and the air outlet 306 on the air outlet pipe 305 is further blocked or exposed, so as to facilitate the adjustment of the size of the air outlet area according to the width of the geotextile body 103, and the air outlet 306 not opposite to the geotextile body 103 is closed, so as to increase the hot air output of the air outlet 306 opposite to the geotextile body 103 when the total amount of hot air remains unchanged, thereby improving the drying effect of the geotextile body 103 while achieving full utilization of the hot air.

[0035] Example 2

[0036] See also Figure 2 This embodiment further illustrates Example 1. The circulation mechanism shown in the figure includes a fixed pipe 701 disposed on one side of the air inlet end of the hot air blower 301. A circulation pipe 702 is fixedly connected to the side wall of the fixed pipe 701. The other end of the circulation pipe 702 is connected to the oven body 102.

[0037] It should be noted here that: through the setting of the circulation mechanism, the suction effect of the hot air blower 301 on the outside during operation is utilized, so that the excess hot air in the oven body 102 is sucked into the hot air blower 301 through the circulation pipe 702, and finally flows into the oven body 102 again, thereby realizing the recycling of hot air, improving thermal efficiency, and further reducing energy consumption.
