DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 41. The moisture recovery device of a composite paper film layer shown in FIG. 1 comprises a machine base 1 and a water tank 4. The device is provided with two machine bases 1, which are symmetrically installed. A water replenishing roller 2 and a moisture recovery roller 3 are rotatably installed between the two machine bases 1. The moisture recovery roller 3 and the water replenishing roller 2 are installed in an upper and lower layout, with the moisture recovery roller 3 on the top and the water replenishing roller 2 on the bottom. The water tank 4 is installed below the water replenishing roller 2. The water tank is filled with replenishing water for moisture recovery. The water replenishing roller 2 is partially immersed in the water tank 4. As the water replenishing roller 2 rotates, the roller surface of the water replenishing roller 2 will continue to pass through the water tank 4, and the water in the water tank 4 will be brought to the roller surface of the water replenishing roller 2. There is a gap between the moisture recovery roller 3 and the water replenishing roller 2, and the moisture recovery roller 3 does not contact the water replenishing roller 2. However, as the water replenishing roller 2 rotates, the water on the roller surface of the water replenishing roller 2 will be thrown onto the moisture recovery roller 3. Due to the moisture recovery The demand is after the oven operation, therefore, the utility model is suitable for being installed at the outlet end of the oven, and the film layer 7 is continuously output from the outlet end of the oven and is transmitted over the rehydration roller 3. The utility model adjusts the rehydration roller 3 to maintain contact with the lower end surface of the film layer 7 (the upper end surface of the film layer 7 is a cured glue layer, and the lower end surface of the film layer 7 has no glue, which is just suitable for rehydration and hydration). As the film layer 7 is transmitted, the rehydration roller 3 continuously forms a hydration and moistening effect on the lower end surface of the film layer 7 to restore the original material properties of the film layer 7 (to solve problems such as water loss and deformation). The utility model forms water-containing moistening through the rotation of the rehydration roller 2 and the rehydration roller 3. The amount of water replenishment is moderate, and a suitable rehydration effect can be formed on the film layer 7. After applying the utility model, the product quality of the composite paper is well stabilized.

[0023] like Figure 2 As shown, the shaft head of the water supply roller 2 is rotatably mounted on the machine base 1, as shown in FIG. Figure 1 As shown, one of the machine bases 1 is equipped with a motor 11, and the output end of the motor 11 is connected to the shaft head of the water supply roller 2. The rotation of the water supply roller 2 is controlled by the motor 11. The faster the speed of the water supply roller 2, the more water it throws off. Figure 4 As shown, a grid layer 21 is provided on the surface of the water replenishing roller 2. The grid layer 21 forms many grid-like concave surfaces on the surface of the water replenishing roller 2. Compared with a smooth roller surface, this will greatly improve the water carrying effect. Figure 3 As shown, there is a gap between the re-humidification roller 3 and the water replenishment roller 2, and the re-humidification roller 3 does not contact the water replenishment roller 2 to avoid the problem of roller surface wear. However, moisture can be thrown onto the roller surface of the re-humidification roller 3 through the rotation of the water replenishment roller 2. The re-humidification roller 3 adopts a rubber roller surface. The rubber roller surface has two advantages. One is to enhance the water viscosity so that the moisture thrown off the water replenishment roller 2 can remain on the roller surface. The other is to protect the film layer 7. The film layer 7 will not be damaged during the contact between the re-humidification roller 3 and the film layer 7. The re-humidification roller 3 adopts a passive transmission mode. Since the film layer 7 is pulled and transmitted and contacts with the re-humidification roller 3, the rotation of the re-humidification roller 3 is driven by the contact friction force. The rotation of the re-humidification roller 3 enables the moisture on its roller surface to continuously moisten the film layer 7.

[0024] In the present invention, the rotation of the rehydration roller 3 is driven by the film layer 7, so the tension between the rehydration roller 3 and the film layer 7 must be ensured. Figure 2 As shown, a tensioning mechanism 6 is installed on the machine base 1, and the shaft head of the rehydration roller 3 is transmission-connected to the tensioning mechanism 6. The tensioning mechanism 6 can ensure that the roller surface of the rehydration roller 3 and the lower end surface of the film layer 7 maintain good tensioning contact.

[0025] like Figure 2 As shown, a slider notch 12 is provided on the machine base 1, and symmetrically arranged guide rails 121 are installed on both sides of the inner wall of the slider notch 12. The guide rails 121 are installed vertically. The tensioning mechanism 6 includes a slider 61 and a screw seat 62. The slider 61 is movably installed on the two guide rails 121. The guide rails 121 play a role in guiding the movement of the slider 61. Since the guide rails 121 are installed vertically, the slider 61 can move vertically. The screw seat 62 is installed across the top of the slider notch 12. A screw 63 is threadedly installed on the screw seat 62. The screw 63 is vertical. It is installed through-through, and the bottom of the screw 63 is rotatably connected to the slider 61. A power-assisting handwheel 64 is fixedly installed on the top of the screw 63. The shaft head of the moisture-recovering roller 3 is rotatably connected to the slider 61. The installation height of the moisture-recovering roller 3 can be adjusted by lifting and lowering the slider 61. The power-assisting handwheel 64 plays a power-assisting role. Rotating the power-assisting handwheel 64 can drive the screw 63 to rotate, and when the screw 63 rotates, it can drive the slider 61 to rise and fall (the bottom of the screw 63 is rotatably connected to the slider 61, so the rotation of the screw 63 cannot realize the rotation of the slider 61, and can only drive the slider 61 to rise and fall).

[0026] The water thrown onto the surface of the moisture-replenishing roller 3 by the water-replenishing roller 2 is uneven, and the amount is difficult to control. Excessive water replenishment is not good for the film layer 7 (the film layer 7 only needs a small amount of water to moisten it back and forth). Therefore, if Figure 1 As shown in the utility model, a moisture regain control mechanism 5 is installed on the side of the moisture regain roller 3, and the moisture on the roller surface of the moisture regain roller 3 is controlled by the moisture regain control mechanism 5. Figure 3 As shown, the moisture recovery control mechanism 5 includes a control frame 51 and a water baffle 52. The water baffle 52 is movably installed on the control frame 51. A plate tip 521 is provided on the water baffle 52. The water baffle 52 is installed with the plate tip 521 facing the roller surface of the moisture recovery roller 3. A gap is left between the plate tip 521 of the water baffle 52 and the roller surface of the moisture recovery roller 3. The water baffle 52 can form a leveling effect on the roller surface of the moisture recovery roller 3 to form a uniform attached water layer. The thickness of the water layer is achieved by controlling the size of the gap between the plate tip 521 and the roller surface of the moisture recovery roller 3. The uniform water layer can achieve uniform water replenishment of the lower end surface of the membrane layer 7. The thin water layer can control the amount of water replenishment, so that the water layer can only meet the moisture recovery and moisturizing requirements.

[0027] like Figure 3As shown, an adjustment platform 53 is connected to the control frame 51, and the moisture recovery control mechanism 5 also includes a pull plate spring 54 and a gap adjuster 55. The water baffle 52 is rotatably installed on the control frame 51 at the non-plate tip 521 end, and the water baffle 52 can realize the overall flipping movement. One end of the pull plate spring 54 is connected to the lower end surface of the water baffle 52, and the other end is connected to the adjustment platform 53. Under the pulling force of the pull plate spring 54, the water baffle 52 can flip toward the roller surface of the moisture recovery roller 3, and the plate tip 521 can approach the roller surface of the moisture recovery roller 3. The gap adjuster 55 is installed on the adjustment platform 53. The gap adjuster 55 can support the water baffle 52 upwards, and the gap adjuster 55 can adjust the gap between the plate tip 521 and the roller surface of the moisture recovery roller 3. 55 includes a bracket 551 and a threaded support rod 552. The threaded support rod 552 is upright mounted on the bracket 551. The threaded support rod 552 is threadedly connected to the bracket 551. The top of the threaded support rod 552 contacts the lower end surface of the water baffle 52. The bottom of the threaded support rod 552 is connected with a screwing head 553. The screwing head 553 can help screw the threaded support rod 552. When the threaded support rod 552 is screwed up, it can lift the water baffle 52. The gap between the plate tip 521 and the roller surface of the rehumidification roller 3 will become larger, the water layer on the roller surface of the rehumidification roller 3 will become thicker, and the amount of water replenishment will increase. When the threaded support rod 552 is screwed down, the water baffle 52 will flip down under the force of the tension plate spring 54, and the plate tip 521 will gradually approach the roller surface of the rehumidification roller 3, which will reduce the amount of water replenishment.

[0028] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
