Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0029] Example: Refer to Figures 1-5, the present utility model provides a technical solution: a pulp washing and filtering device for napkin production, including a bottom plate 1 and a washing and filtering mechanism 3, and a partition plate 2 is installed on the upper surface of the bottom plate 1. The washing and filtering mechanism 3 includes a positioning plate 31, the positioning plate 31 is fixedly installed on the upper surface of the bottom plate 1, and a hollow cylinder 311 is rotatably arranged inside the positioning plate 31 for containing pulp. The filter plate 32 is arranged in an arc shape below the hollow cylinder 311, and the filter plate 32 is driven to move by the hollow cylinder 311. A number of small holes 321 are arranged on the outer surface of the filter plate 32. A baffle plate 33 is installed on the side of the filter plate 32 for limiting the pulp.

[0030] In a preferred embodiment, two partition plates 2 are provided and installed on both sides of the filter plate 32 for limiting the filter plate 32, and the filter plate 32 is arranged to move between the two partition plates 2. In actual use of this device, by controlling the left and right swing of the filter plate 32, the side of the filter plate 32 will abut against the inner side surface of the partition plate 2, thereby limiting the filter plate 32 and preventing the pulp falling on the filter plate 32 from being thrown out from the side of the filter plate 32, and controlling all the pulp to fall from the position of the small holes 321, improving the filtering effect of the pulp.

[0031] In a preferred embodiment, a servo motor 4 is fixedly installed on the outer surface of the positioning plate 31, and the hollow cylinder 311 is installed at the output end of the servo motor 4. The servo motor 4 is electrically connected to a PLC controller 5. To facilitate driving the rotation of the hollow cylinder 311, a servo motor 4 is installed on the outer side surface of the positioning plate 31. The hollow cylinder 311 is driven to rotate by the servo motor 4 to drive the pulp inside the hollow cylinder 311 to move. As the pulp continuously moves inside the hollow cylinder 311, the pulp will have a certain impact force when falling, avoiding blockage at the discharge hole 9 and being convenient for use.

[0032] In a preferred embodiment, a bearing plate 6 is also stably installed on the outer surface of the positioning plate 31, and the servo motor 4 is installed on the upper surface of the bearing plate 6. The bottom of the bearing plate 6 is fixedly connected to a triangular plate 7, and one side surface of the triangular plate 7 is fixedly connected to the outer side surface of the positioning plate 31. To ensure the stable use of the servo motor 4 in this device, a bearing plate 6 is installed on the outer surface of the positioning plate 31, and a triangular plate 7 is also installed at the bottom of the bearing plate 6. The triangular plate 7 has stability, thereby stably installing and using the servo motor 4.

[0033] In actual operation, for the convenience of feeding and discharging, a feeding bin 8 is installed on the hollow cylinder 311, and a discharge hole 9 is provided at the bottom of the hollow cylinder 311. Link rods 10 are respectively installed at both ends of the hollow cylinder 311. The bottom end of the link rod 10 is stably connected to the filter plate 32. Pulp and water are added into the hollow cylinder 311 and continuously shaken inside the hollow cylinder 311, which can wash the pulp, and the washed pulp is discharged from the position of the discharge hole 9. The washed pulp will fall onto the filter plate 32 to filter the washed pulp for easy use.

[0034] After filtering the pulp, the pulp will continuously fall from the filter plate 32. To facilitate the treatment of the pulp, a discharging mechanism 11 is installed on the bottom plate 1. The discharging mechanism 11 includes a convex block 111, a pushing plate 112 and a collecting trough 113. The collecting trough 113 is opened on the upper surface of the bottom plate 1, and a pushing plate 112 is arranged inside the collecting trough 113. An electric telescopic rod 12 is stably installed on the outer surface of the bottom plate 1. The pushing plate 112 is installed at the telescopic end of the electric telescopic rod 12. A convex block 111 is stably installed at the middle position of the upper surface of the bottom plate 1, and the collecting trough 113 is arranged at the side of the convex block 111 for conveying the pulp into the collecting trough 113.

[0035] During actual use, the pulp falls from the filter plate 32 and lands on the outer surface of the convex block 111, and then slides into the collecting trough 113. The pulp is collected inside the collecting trough 113. During actual operation, the clamping block inside the collecting trough 113 is removed. When a certain amount of pulp is stored inside the collecting trough 113, it will automatically flow out for discharging. After the filtering of the pulp is completed, the electric telescopic rod 12 can be used to push the pushing plate 112 to move inside the collecting trough 113 to push out the pulp inside the collecting trough 113, which is convenient for discharging the pulp and convenient for use.

[0036] Specifically, the working process or principle of a pulp washing and filtering device for producing napkins is as follows: Currently, the method of filtering pulp is to place the pulp on a filter plate and then control a cleaning brush to scrape the pulp so that the pulp can fall from the filter plate, and the impurities are filtered on the filter plate to achieve filtration. However, in actual operation, when using the cleaning brush to scrape the pulp, after repeated scraping, a large amount of pulp will adhere to the cleaning brush. When the pulp accumulates to a certain thickness on the cleaning brush, it will affect the scraping effect on the pulp, and thus affect the scraping effect on the pulp. Therefore, this device is designed to solve this problem.

[0037] This device can drive the filter plate 32 to move in a swinging manner, thereby swinging the washed pulp to achieve the filtration of the pulp on the filter plate 32, which is convenient for use. The specific operation is as follows: Connect to an external power supply, add the pulp and water to the inside of the hollow cylinder 311 from the feeding bin 8, and wash the pulp with water. Although there is a discharge hole 9 at the bottom of the hollow cylinder 311, the pulp and water will drain through the position of the discharge hole 9. Since the diameter of the discharge hole 9 is smaller than that of the feeding bin 8, a small amount of pulp will be discharged. After a certain amount of pulp is added to the inside of the hollow cylinder 311, the servo motor 4 is then turned on.

[0038] Drive the hollow cylinder 311 to rotate through the servo motor 4. This device controls the left and right rotation of the hollow cylinder 311, and the rotation angle each time is less than 90 degrees. By controlling the rotation of the hollow cylinder 311, the pulp swings inside the hollow cylinder 311 and is thrown out from the position of the discharge hole 9. The pulp will fall onto the filter plate 32 for filtering the pulp.

[0039] To facilitate the filtration of the pulp, this device drives the linkage rod 10 to move while the hollow cylinder 311 rotates. The linkage rod 10 is stably connected to the filter plate 32, which will drive the filter plate 32 to swing, thereby driving the pulp to continuously move on the filter plate 32, causing the pulp to flow out from the inside of the small holes 321, filtering the impurities on the filter plate 32, and thus achieving the filtration of the pulp. This effectively replaces the prevention of scraping by the cleaning brush. The pulp will flow out in small amounts at multiple positions during continuous movement, improving the filtration effect.

[0040] When the pulp falls onto the outer surface of the convex block 111, it will slide into the inside of the aggregate trough 113. The pulp will be collected inside the aggregate trough 113. In actual operation, the clamping block inside the aggregate trough 113 is removed. When a certain amount of pulp is stored inside the aggregate trough 113, it will automatically flow out for discharging. After the filtration of the pulp is completed, the electric telescopic rod 12 can be used to push the pushing plate 112 to move inside the aggregate trough 113, pushing out the pulp inside the aggregate trough 113 for collection.

[0041] It should be noted that the servo motor 4, the PLC controller 5, and the electric telescopic rod 12 are devices or equipment existing in the prior art, or devices or equipment that can be realized by the prior art. Their power supply, specific composition, and principle are clear to those skilled in the art, so they will not be elaborated in detail.
