Description

Technical Field

[0001] The utility model relates to the technical field of pulp molding, in particular to a pulp tank of a pulp molding machine. Background Art

[0002] Pulp molding is a three-dimensional papermaking technology. It uses waste paper as raw material and special molds on a molding machine to shape paper products of a certain shape. During the production process, the molding mold needs to reciprocate up and down in the pulp in the pulp tank to absorb pulp for shaping. During the reciprocating up and down movement of the molding mold, the pulp water in the pulp tank will inevitably overflow to the outer cavity and then be discharged. The inner cavity of the traditional pulp tank is generally square, and there are dead corners in the inner cavity. During the reciprocating up and down movement of the molding mold, phenomena such as uneven pulp water concentration, insufficient pulp volume, sediment accumulation, and overflow and splashing will occur.

[0003] In the process of pulp molding, a pulp tank of a pulp molding machine is required. The Chinese utility model patent with the publication number CN212801029U discloses a paper pulp tank, which includes a tank body. The tank body is divided into an inner cavity and an outer cavity by a partition board. The height of the partition board is lower than the height of the side plate of the tank body. The partition board includes a vertical section, and the lower end of the vertical section is connected to a downward inclined section. The downward inclined section inclines towards the center of the tank body. An overflow hole is opened in the outer cavity, and a pulp inlet, a lifting component installation hole, and a pulp suction pipe installation hole are opened at the bottom of the inner cavity. This utility model uses the paper pulp tank to solve the problems of uneven pulp water concentration, insufficient pulp volume, sediment accumulation, and overflow and splashing in the traditional paper pulp tank.

[0004] However, this utility model paper pulp tank has problems such as uneven pulp distribution, easy generation of bubbles, and difficult cleaning and maintenance during the pulp storage and transportation process, which affect the molding quality and production efficiency and cannot meet the production requirements. Therefore, a pulp tank of a pulp molding machine is proposed to solve the problems raised above. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a pulp tank of a pulp molding machine, which has the advantages of good molding quality and strong practicability, and solves the problems of uneven pulp distribution, easy generation of bubbles, and difficult cleaning and maintenance in the existing paper pulp tank during the pulp storage and transportation process, which affect the molding quality and production efficiency and cannot meet the production requirements.

[0006] To achieve the above object, the utility model provides the following technical solution: A pulp tank of a pulp molding machine, including a pulp tank body, a vacuum chamber arranged inside the pulp tank body, and a pulp fishing mold arranged on the top of the vacuum chamber. A blowing device for preventing precipitation is arranged inside the pulp tank body, and a pulp inlet guide groove is arranged inside the pulp tank body.

[0007] The blowing device includes a number of air pipes fixedly connected to the inner bottom wall of the pulp tank body. A number of air holes are provided inside the air pipes, and one end of the air pipe extending outside the pulp tank body is fixedly communicated with a connector.

[0008] The pulp inlet guiding groove is composed of a transverse folding plate and a vertical folding plate, and pulp outlet holes are evenly provided at the bottom edge of the vertical folding plate.

[0009] Furthermore, nuts are threadedly connected to the ends of a number of the air pipes. The number of the air pipes are evenly distributed inside the pulp tank body, and a connecting pipe communicated with the connector is fixedly installed outside the pulp tank body.

[0010] Furthermore, two tie rods are fixedly connected inside the pulp tank body, and the vacuum chamber is slidably connected to the outside of the tie rods.

[0011] Furthermore, a vacuum interface flange is fixedly installed outside the pulp tank body. A vacuum hose extending inside the pulp tank body is fixedly communicated inside the vacuum interface flange, and a fixing plate adapted to the vertical folding plate is fixedly connected to the inner top wall of the pulp tank body.

[0012] Furthermore, overflow ports are provided at both ends of the pulp tank body. Overflow troughs are provided outside the two overflow ports, and lead-out pipes are fixedly communicated with the bottoms of the two overflow troughs.

[0013] Furthermore, the pulp tank body is a hollow cuboid, and four pulp inlet ports are fixedly communicated with the outside of the pulp tank body.

[0014] Furthermore, a maintenance opening is provided on the front surface of the pulp tank body. A cover plate is detachably connected to the outside of the maintenance opening, and a sealing gasket is fixedly installed between the maintenance opening and the cover plate.

[0015] Compared with the prior art, the present utility model provides a pulp tank of a pulp molding machine, which has the following beneficial effects:

[0016] 1. For the pulp tank of the pulp molding machine, compressed air is injected into the blowing device through the connecting pipe. The compressed air enters the air pipes through the connector, so that the air output of each air pipe is similar. Furthermore, when compressed air is blown, it blows out from the air holes at the lower part of the air pipes to stir the slurry, making the pulp water more uniform and preventing bottom precipitation. The solid pulp particle fibers that originally sank downward are not easy to deposit, and the concentration of the pulp tank is kept consistent up and down. While feeding pulp, the pulp water can also be stirred at the same time, making the pulp water mix more evenly and not easy to deposit. The pulp water is injected into the pulp inlet guiding groove through the pulp inlet at a constant concentration and a constant flow rate for spraying, which plays a role in stirring and achieves the advantage of good molding quality.

[0017] 2. The pulp molding machine pulp tank. By setting overflow ports at both ends of the pulp tank body, when the pulp fishing mold descends, the water displaced by the pulp fishing mold will quickly overflow from the overflow ports and flow into the inside of the overflow pulp tank, reducing the problem that water waves will repeatedly collide and oscillate between the surface of the pulp fishing mold and the tank wall, affecting the adsorption effect of several cavities around the pulp fishing mold. This makes the pulp adsorption molding more uniform and the weight deviation of the products smaller. By setting a maintenance port and a cover plate, it is convenient to repair and clean the inside of the pulp tank body, achieving the advantage of strong practicability. Description of the Drawings
