Moreover, with the cooperation of the drying trough 3 and the first scissor-type frame 4, the lower two sides of the glass fibers during spreading can be interchanged with each other, thereby effectively improving its drying efficiency.

[0021] Among them, two left and right chutes 5 are opened on the front and rear sides of the first drying tray 1 and located below the drying tank 3 on its top. The front and rear ends of the adjustment mechanism 7 pass through the chutes 5 and extend to the front and rear sides of the first drying tray 1 and are connected to the lower end of the first scissors frame 4.

[0022] Among them, two left and right slots 6 are opened on the front and back sides of the second drying tray 2. The cross-section of the slot 6 is a horizontal "T" shape. The inside of the slot 6 is slidably connected with a connecting shaft. The front of the connecting shaft passes through the slot 6 and extends to the front and back sides of the second drying tray 2 and is connected to the rotating shaft of the first scissor-type frame 4; due to the setting of the slide slot 5, the adjustment mechanism 7 can be connected to the lower end of the first scissor-type frame 4, and the movement of the adjustment mechanism 7 can be restricted, so that the adjustment mechanism 7 moves smoothly with the first scissor-type frame 4; and the setting of the slot 6 allows the rotating shaft end of the adjustment mechanism 7 to slide along the surface of the second drying tray 2, so that the extension and contraction of the first scissor-type frame 4 can simultaneously drive several second drying trays 2 to move away from or closer to each other.

[0026] The inner wall size of the positioning slot 724 matches the outer surface size of the limiting block 722. The outer surface of the limiting block 722 and the inner wall of the positioning slot 724 are smooth. The arc length between the two corresponding limiting blocks 722 is greater than the arc length of the positioning block 723. The plurality of limit blocks 722 and positioning blocks 723 are alternately distributed, and the distance between two adjacent limit blocks 722 is adapted to the thickness of the positioning blocks 723, and the distance between two adjacent positioning blocks 723 is adapted to the thickness of the limit blocks 722; due to the provision of the positioning slots 724, the linkage rod 711 can drive the positioning block 723 under the action of gravity, so that the positioning slots 724 are automatically engaged with the limit blocks 722, which can prevent the adjustment rod 721 from accidentally rotating, thereby ensuring that the distance between the first drying tray 1 and the plurality of second drying trays 2 remains stable; at the same time, the limit blocks 722 and positioning blocks 723 corresponding to the upper and lower corresponding limit blocks 722, and the distance between the upper and lower corresponding limit blocks 722 is greater than the arc length of the positioning block 723, can ensure that the positioning block 723 can slide quickly between the upper and lower limit blocks 722, so as to improve the efficiency of adjusting the distance between the first drying tray 1 and the plurality of second drying trays 2.

By turning any of the first knobs 73, the limit block 722 on its surface is rotated through the adjustment rod 721, so that the limit block 722 and the positioning block 723 are displaced from each other. Then, the second drying tray 2 is released, and the first drying tray 1 and the second drying tray 2 are quickly engaged with each other in cooperation with the first scissor frame 4. S6. The glass fiber paving is encapsulated in the first drying tray 1 and several second drying trays 2 facing the drying tank 3, and then reverse operation of the adjustment mechanism 7, so that the first drying tray 1 and several second drying trays 2 are tightly engaged with each other; S7. Under the connection limit of the upper end of the lifting frame 8, rotate the first drying tray 1 and several second drying trays 2 as a whole, so that the upper and lower sides of the glass fiber paved within the drying tank 3 can be swapped with each other; S8 repeat the above-mentioned operation of the adjustment mechanism 7, so that the first drying tray 1 and the second drying tray 2 are away from each other until the glass fiber spread in the drying tank 3 is dried again; S9. After drying, the first drying tray 1 and the second drying tray 2 are tightly fastened together by the adjustment mechanism 7, and then the first drying tray 1 and the second drying tray 2 are fastened to each other by the sliding mechanism, so that the entire device is in a flat state for easy storage; S10.

Under the connection limit of the upper end of the lifting frame (8), the first drying plate (1) and the plurality of second drying plates (2) are rotated as a whole, so that the upper and lower sides of the glass fiber packaged and spread in the drying tank (3) are interchanged; S8. Repeat the operation of the adjustment mechanism (7) to move the first drying plate (1) and the plurality of second drying plates (2) away from each other until the glass fibers spread in the drying tank (3) are dried again; S9. After the drying is completed, the first drying tray (1) and the plurality of second drying trays (2) are tightly fastened together by the adjusting mechanism (7), and then the first drying tray (1) and the plurality of second drying trays (2) that are fastened to each other are attached to the top of the sliding mechanism by the sliding mechanism, so that the entire device is in a flat state for easy storage; S10. Specifically, any one of the second knobs (16) is rotated to drive the two connecting rods (14) toward each other through the screw rod (15), and then the lower ends of the lifting frame (8) are pushed away from each other through the linkage sleeve (12), the transmission rod (10) and the support frame (9), until the first drying tray (1) and the plurality of second drying trays (2) that are interlocked with each other are attached to the top of the sliding mechanism.
