[0014] A wrinkle-resistant finishing process for full-light-shielding fabrics, comprising the following steps: S1. In the initial state, the full-shading fabric to be processed is placed in the placement frame. Under the gravity of the full-shading fabric, the sliding plate and the sliding block move downward synchronously, so that the first spring is compressed for a certain distance. In the initial state, the limit rod is inserted into the limit hole to keep the baffle in a vertical state. S2, start the servo motor, the servo motor rotates forward, the servo motor drives the lead screw of the ball screw to rotate, under the action of the guide rod, the nut of the ball screw drives the support plate to move vertically downward, while the support plate moves vertically downward, the placement frame, the sliding plate, the sliding block, the first spring, the rotating block, the rotating shaft, the baffle, the limit plate and the full light-shielding fabric inside the placement frame move downward synchronously, when the support plate moves to the bottom, turn off the servo motor, during this process, the limit plate keeps moving vertically downward along the trajectory of the limit rod, so that the baffle always keeps a vertical state and does not rotate, at this time the placement frame is completely immersed in the aqueous solution containing the anti-wrinkle finishing agent in the sorting box, so as to immerse the full light-shielding fabric to achieve the anti-wrinkle effect; S3. Turn on the servo motor again, the servo motor reverses, and the servo motor drives the lead screw of the ball screw to rotate. Under the action of the first guide rod, the nut of the ball screw drives the support plate to move vertically upward. While the support plate moves vertically upward, the placement frame, the sliding plate, the sliding block, the first spring, the rotating block, the rotating shaft, the baffle plate, the limit plate and the full-light-shielding fabric inside the placement frame move up synchronously. During this process, the full-light-shielding fabric inside the placement frame contacts the pressing plate and gradually squeezes the pressing plate. As the pressing plate and the second guide rod move vertically upward until the first block is blocked by the L-shaped blocking plate, that is, when it reaches the final position. After the pressing plate is pressed upward, it stops moving, and the second spring is also compressed for a certain distance. During this process, the limit plate is disengaged from the limit rod after moving upward for a certain distance, and the trapezoidal block contacts and squeezes the pressing plate after moving upward for a certain distance. After the inclined surface of the trapezoidal block is subjected to an extrusion force, a rotational force is formed, so that the baffle plate rotates a certain angle along the rotating shaft, thereby facilitating the full-shading fabric to be taken out from the inside of the placement frame. As the pressing plate squeezes the full-shading fabric inside the placement frame, the aqueous solution containing the anti-wrinkle finishing agent in the full-shading fabric is squeezed out and flows back to the inside of the storage box through the sliding plate and the through holes at the bottom of the placement frame; S4, turn on the servo motor, the servo motor rotates forward, the servo motor drives the lead screw of the ball screw to rotate, under the action of the guide rod, the nut of the ball screw drives the support plate to move vertically downward, while the support plate moves vertically downward, the placement frame, the sliding plate, the sliding block, the first spring, the rotating block, the rotating shaft, the baffle, the limit plate and the full-shading fabric inside the placement frame move downward synchronously, so that the placement frame moves down to the initial position. At this time, since the baffle has rotated a certain angle, the full-shading fabric can be taken out from one side of the opening of the placement frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The full-light-shielding fabric in the present invention is treated with anti-wrinkle by being immersed in the anti-wrinkle finishing agent aqueous solution contained in the storage box. After the anti-wrinkle treatment is completed, the placement frame gradually moves upward. During this process, the trapezoidal block will contact and squeeze the pressing plate. At this time, the inclined surface of the trapezoidal block is subjected to a squeezing force and then forms a rotational force, causing the baffle to rotate a certain angle along the rotating shaft. At the same time, the full-light-shielding fabric inside the placement frame will contact the pressing plate. Subsequently, in the process of squeezing the pressing plate, the aqueous solution containing the anti-wrinkle finishing agent inside the full-light-shielding fabric is squeezed out and flows into the storage box through the through hole.

[0033] Specifically, second stoppers 22 are fixedly installed on both sides of the interior of the placement frame 2, and the second stoppers 22 are used to block and limit the baffle 15 so that the baffle 15 remains in a vertical state.

[0034] In the above embodiment, the second stopper 22 serves to block and limit the position, thereby ensuring that the baffle 15 is in a vertical position in the closed state.

[0035] Working principle: S1. In the initial state, the full-shading fabric to be processed is placed in the placement frame 2. Under the gravity of the full-shading fabric, the sliding plate 24 and the sliding block 4 move downward synchronously, so that the first spring 6 is compressed for a distance, and in the initial state, the limiting rod 17 is inserted into the limiting hole to keep the baffle 15 in a vertical state; S2, start the servo motor 9, the servo motor 9 rotates forward, the servo motor 9 drives the screw of the ball screw 8 to rotate, under the action of the guide rod 23, the nut of the ball screw 8 drives the support plate 7 to move vertically downward, while the support plate 7 moves vertically downward, the placement frame 2, the sliding plate 24, the sliding block 4, the first spring 6, the rotating block 13, the rotating shaft 14, the baffle 15, the limit plate 16 and the full light-shielding fabric inside the placement frame 2 move downward synchronously, when the support plate 7 moves to the bottom, turn off the servo motor 9, during this process, the limit plate 16 keeps moving vertically downward along the trajectory of the limit rod 17, so that the baffle 15 always keeps a vertical state and does not rotate, at this time the placement frame 2 is completely immersed in the aqueous solution containing the anti-wrinkle finishing agent in the sorting box 1, so as to perform an anti-wrinkle treatment on the full light-shielding fabric, so that it can achieve an anti-wrinkle effect; S3. Turn on the servo motor 9 again, and the servo motor 9 reverses. The servo motor 9 drives the screw of the ball screw 8 to rotate. Under the action of the first guide rod 23, the nut of the ball screw 8 drives the support plate 7 to move vertically upward. When the support plate 7 moves vertically upward, the placement frame 2, the sliding plate 24, the sliding block 4, the first spring 6, the rotating block 13, the rotating shaft 14, the baffle 15, the limit plate 16 and the full light-shielding fabric inside the placement frame 2 move up synchronously. During this process, the full light-shielding fabric inside the placement frame 2 contacts the pressing plate 10 and gradually squeezes the pressing plate 10. As the pressing plate 10 and the second guide rod 18 move vertically upward until the first block 20 is blocked by the L-shaped blocking plate 26. That is, it stops moving after reaching the top, and the second spring 12 is also compressed for a certain distance. During this process, the limit plate 16 moves up and disengages from the limit rod 17, and the trapezoidal block 25 contacts and squeezes the pressing plate 10 after moving up for a certain distance. After the inclined surface of the trapezoidal block 25 is subjected to an extrusion force, a rotational force is formed, so that the baffle 15 rotates a certain angle along the rotating shaft 14, so as to facilitate the full-shading fabric to be taken out from the inside of the placement frame 2. Since the pressing plate 10 squeezes the full-shading fabric inside the placement frame 2, the aqueous solution containing the anti-wrinkle finishing agent in the full-shading fabric is squeezed out and flows back to the inside of the storage box 1 through the sliding plate 24 and the through hole 5 at the bottom of the placement frame 2; S4, turn on the servo motor 9, the servo motor 9 rotates forward, and the servo motor 9 drives the screw of the ball screw 8 to rotate. Under the action of the guide rod 23, the nut of the ball screw 8 drives the support plate 7 to move vertically downward. When the support plate 7 moves vertically downward, the placement frame 2, the sliding plate 24, the sliding block 4, the first spring 6, the rotating block 13, the rotating shaft 14, the baffle 15, the limit plate 16 and the full-shading fabric inside the placement frame 2 move downward synchronously, so that the placement frame 2 moves down to the initial position. At this time, since the baffle 15 has rotated a certain angle, the full-shading fabric can be taken out from the side of the opening of the placement frame 2.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
