Description

Technical Field

[0001] The invention relates to pulp molding equipment, in particular to a rotary drainage mechanism of a pulp double-sided molding die. Background Art

[0002] Pulp molding is a three-dimensional papermaking technology that uses waste paper as raw material. Paper products of a certain shape are formed by special molds on a molding machine. The double-sided pulp molding mold consists of two molding surfaces, an upper and a lower molding surface, which can be molded separately by rotation. During the molding process, water vapor needs to be discharged to leave the pulp on the filter screen of the mold. Traditional operation requires that both the upper and lower molding surfaces are connected to a set of drainage mechanisms. Generally, in order to prevent mutual interference, they need to be connected to both sides of the mold respectively. The required installation space is large, the structure is complex, and the installation is troublesome. In addition, the traditional drainage mechanism has the problem of poor drainage.

[0008] The drainage pipe body is provided with a sealing groove at the position of the sealing sleeve, and a sealing ring is provided in the sealing groove.

[0009] The sealing head is connected to the end of the drainage pipe body through screws.

[0010] The beneficial effects of the present invention are as follows: the rotary drainage pipe of the slurry double-sided forming mold is connected to the drainage channels on the upper and lower sides of the mold at the same time through a drainage pipe body. It only needs to be installed on one side, the required installation space is small, and the structure is compact and easy to install. In addition, the drainage through hole and the vertical water outlet pipe are located at the lowest point, and the drainage is smooth. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The specific implementation of this embodiment is described below with reference to the accompanying drawings.

[0019] like Figures 1 to 6As shown, the rotary drainage mechanism of the pulp double-sided forming mold of this embodiment includes a drainage pipe body 1, one end of the drainage pipe body 1 is connected to the pulp double-sided forming mold through a flange 11, and the other end is sealed by a head 2, and the head 2 is connected to the end of the drainage pipe body 1 by screws. The drainage pipe body 1 is divided into two drainage chambers 13 by a vertical partition 12. The two drainage chambers 13 are respectively connected to the drainage channels on the upper and lower sides of the pulp double-sided forming mold. Two drainage through holes 14 are provided at different positions on the upper and lower sides of the drainage chamber 13. The drainage pipe body 1 A sleeve 3 is provided on the outside of the drainage through-hole 14 located outside the two drainage cavities 13, and a sealing sleeve 4 is installed between the two ends of the two sleeves 3 and the drainage pipe body 1, and a sealing sleeve baffle 41 is provided on the outside of the sealing sleeve 4 of the drainage pipe body 1. A sealing groove 15 is provided at the position of the drainage pipe body 1 located at the sealing sleeve 4, and a sealing ring 16 is provided in the sealing groove 15. The lower side of the sleeve 3 is connected to a vertical water outlet pipe 31, and the vertical water outlet pipes 31 of the two sleeves 3 can be respectively connected to the drainage through-hole 14 on the lower side of the two drainage cavities 13, and the vertical water outlet pipes 31 are both connected to the negative pressure pipeline.

[0020] When installing the rotary drainage mechanism of the pulp double-sided forming mold of this embodiment, first insert the sealing ring 16 into the sealing groove 15, then put the sealing sleeve baffle 41, the sealing sleeve 4, and the sleeve 3 onto the outside of the drainage pipe body 1, and then connect the head 2 to the end of the drainage pipe body 1 to seal the end of the drainage pipe body 1. At the same time, the sealing sleeve 4 and the sleeve 3 are positioned by the head 2 in conjunction with the step on the drainage pipe body 1. Finally, the drainage pipe body 1 is connected to the pulp double-sided forming mold through the flange 11, and the two drainage cavities 13 are respectively connected to the drainage channels on the upper and lower sides of the pulp double-sided forming mold to complete the installation of the rotary drain pipe. After installation, the pulp double-sided forming mold can be used to rotate the drainage mechanism. When the mold is draining, the negative pressure device of the negative pressure pipe is opened, and the drainage channel on the pulp double-sided forming mold sends the moisture on the mold into the drainage cavity 13 of the drainage pipe body 1, and is discharged through the drainage through hole 14 on the lower side, and is discharged through the vertical outlet pipe 31 connected to the drainage through hole 14 on the lower side. The moisture can be discharged into the negative pressure pipeline, and when the pulp double-sided forming mold is rotated 180°, the drainage pipe body 1 also rotates 180°, so that the drainage through hole 14 on the other side can move to the lowermost side and connect with the vertical outlet pipe 31, and normal drainage can still be achieved.
