Description

Technical Field

[0001] The utility model relates to the technical field of reducing slurry accumulation at a limit position of a pulp suction mold of a pulp molding turnover machine, in particular to a device for reducing slurry accumulation at a limit position of a pulp suction mold of a pulp molding turnover machine. Background Art

[0002] During the turning process of the pulp suction mold of the pulp molding turning machine, the excess slurry will flow on the slurry suction mold and finally gather at the edge of the lower slurry suction mold, causing slurry accumulation here; the accumulated slurry reaches the hot pressing mold, causing the temperature of the hot pressing mold to be low, and the dried slurry becomes dry slurry to block the exhaust hole, reducing the maintenance cycle of the mold;

[0003] The inherent characteristics of the current turning machine, coupled with the fact that water flows from high to low, result in more slurry on the side of the mold below when the slurry suction mold is turned over. Before it is turned over and closed with the hot pressing mold, the excess slurry cannot fall into the slurry pool and is adsorbed on the slurry suction mold and the hot pressing mold, causing the hot pressing mold to have a low temperature and more dry slurry, resulting in abnormal product size, more dark spots, and a decrease in product yield. Therefore, we proposed a device to reduce the accumulation of slurry at the limit of the slurry suction mold of the pulp molding turning machine. Utility Model Content

[0004] The utility model aims to provide a device for reducing the accumulation of pulp at the limit position of the pulp suction mold of a pulp molding turnover machine, thereby solving the existing problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A device for reducing slurry accumulation at the limit position of a pulp molding turning machine comprises a pulp suction mold frame, the four outer corners of the pulp suction mold frame are provided with pulp suction mold bottom frame slopes, the inner side of the pulp suction mold frame is fixedly installed with a pulp suction mold pressing screen frame, the four top corners of the pulp suction mold frame are fixedly installed with pulp suction mold limiters, the inner side of the pulp suction mold pressing screen frame is fixedly installed with a plurality of pulp suction mold cores, and the four outer corners of the pulp suction mold pressing screen frame are provided with a plurality of screen pressing frame slopes.

[0007] By adopting the above technical scheme, the device makes the slurry suction mold screen frame into a sloped surface, the slurry suction mold frame into a sloped surface, and changes the L-shaped limit of the slurry suction mold into a letter-shaped limit; reduces the obstruction of the slurry flow, accelerates the slurry to fall into the slurry pool, thereby reducing the excess slurry to form dry slurry when the slurry suction mold and the hot pressing film are molded, thereby reducing the dark color of the product and reducing the heat loss of the hot pressing mold; the device can reduce the generation of product discoloration; it can reduce the generation of dry slurry in the hot pressing lower mold and extend the maintenance cycle.

[0008] As a further improvement of the above solution, a plurality of threaded holes are provided on the top and bottom of the slurry suction mold frame and the slurry suction mold pressing screen frame, and mounting grooves are provided inside the threaded holes.

[0009] By adopting the above technical scheme, the threaded hole makes it easy for the slurry absorption mold core to be installed above the slurry absorption mold pressing screen frame, and the slurry absorption mold pressing screen frame can be installed above the slurry absorption mold frame, so that the connection and fixation are more stable, and the installation groove makes it difficult for the fixing bolts to protrude, making it difficult for the slurry to enter the inner side of the threaded hole.

[0010] As a further improvement of the above scheme, a fixing bolt is installed on the inner thread of the threaded hole, and the fixing bolt is convex in shape. The inner diameter of the threaded hole is the same as the smallest outer diameter of the fixing bolt, and the inner diameter of the mounting groove is the same as the largest outer diameter of the fixing bolt.

[0011] By adopting the above technical solution, the fixing bolt is closely fitted with the threaded hole and the installation groove after installation, so that the integrity is stronger.

[0012] As a further improvement of the above scheme, the shape of the slurry suction mold limiter is I-shaped, and a chamfer is provided at the connection between the slope of the slurry suction mold bottom frame and the slurry suction mold pressing mesh frame and the slurry suction mold limiter.

[0013] By adopting the above technical scheme, the accumulation of slurry caused by the dead corner of the "L"-shaped limit is avoided; the slurry at the limit of the slurry suction mold is reduced, and when the slurry suction mold and the hot pressing lower mold are closed, the slurry flowing from the slurry suction mold to the hot pressing lower mold is also reduced, which is beneficial to the increase of the temperature of the hot pressing lower mold and saves the heating energy consumption of the lower mold; the reduction of slurry also simultaneously reduces the generation of dry slurry in the lower mold, thereby extending the maintenance cycle of the lower mold.

[0014] As a further improvement of the above solution, chamfers are provided at the connection between the slurry suction mold screen frame and the screen frame slope and the slurry suction mold core.

[0015] By adopting the above technical solution, the inclined slurry absorption molded screen frame and mold frame are more conducive to the flow of slurry, reduce obstacles, and make the slurry flow into the slurry box faster.

[0016] As a further improvement of the above solution, the slope of the bottom frame of the slurry suction mold and the slope of the screen pressing frame are opened and chamfered.

[0017] By adopting the above technical solution, the slope of the bottom frame of the slurry absorption mold and the slope of the screen pressing frame are not easy to accumulate residual slurry, so that the slurry can be discharged more conveniently and is not easy to accumulate, so that the later cleaning is more convenient.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The device makes the screen frame of the slurry suction mold into a sloped surface, the slurry suction mold frame into a sloped surface, and changes the L-shaped limit of the slurry suction mold into a I-shaped limit; reduces the obstruction of the slurry flow, accelerates the slurry to fall into the slurry pool, thereby reducing the excess slurry to form dry slurry when the slurry suction mold and the hot pressing film are molded together, thereby reducing the dark color of the product and reducing the heat loss of the hot pressing mold; the device can reduce the generation of product discoloration; it can reduce the generation of dry slurry in the hot pressing mold and extend the maintenance cycle.
