Technical Field

[0001] This utility model relates to the field of papermaking technology, and in particular to a vacuum suction dehydration device for household paper. Background Technology

[0002] The production process of household paper mainly includes the pulping section and the papermaking section. Currently, the raw materials used in the pulping section are mostly pulp boards produced by pulp mills. The pulp boards are first processed into wet pulp through processes such as pulping, sand removal, and refining. Then, the pulp enters the paper machine and goes through the wire pressing, drying, and other papermaking sections. The wet pulp setting device uses high vacuum to draw wet paper sheets from the back of the fabric to form relevant textures and increase the bulk of the paper sheets.

[0003] In the prior art, the structure of paper wet pulp setting devices is relatively simple. These devices cannot quickly remove the set wet pulp, thus affecting the setting of the paper wet pulp. To address this issue, application number 202220565817.3 discloses a wet pulp setting device for household paper, which includes a forming section, a conveying section, a drying section, and a winding section arranged sequentially. A mold belt section is provided between the conveying section and the drying section. The mold belt section includes an automatic force mold belt. A shoe pressure roller is installed at the bottom of the input end of the automatic force mold belt. A counter pressure roller is installed on the inner side of the automatic force mold belt opposite to the shoe pressure roller. The drying section is composed of a Yankee cylinder. A flat transfer press roller is installed on the inner side of the automatic force mold belt opposite to the Yankee cylinder.

[0004] The above-mentioned patent has the following problems when used: When using it, the staff needs to manually spread the pulp discharged from the pulp guide pipe, which is time-consuming and labor-intensive; moreover, manual operation is prone to uneven spreading of pulp, which affects product quality, and there is room for improvement.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0030] The fixing mechanism 6 includes a cylinder 61, a U-shaped plate 62, a telescopic plate 63, a shaping frame 64, a pressure plate 65, a threaded rod 66, and a limiting plate 67.

A sealing ring is provided on the screen plate 3 and is tightly connected to the machine housing 2 to improve the sealing performance. One end of the cylinder 61 is fixedly connected to the U-shaped plate 62. Two telescopic plates 63 are slidably connected to the U-shaped plate 62. One end of the two telescopic plates 63 is fixedly connected to the same shaping frame 64. The shaping frame 64 abuts against the screen plate 3. Through the cooperative design between the machine housing 2, the cover plate 4, the fixing mechanism 6, the screen plate 3, and the control panel 5, the effect of automatically and evenly spreading the pulp can be achieved, improving convenience and product quality.

[0031] In this embodiment, a pressure plate 65 is fixedly installed at the output end of the cylinder 61. The pressure plate 65 is slidably connected to and adapted to the shaping frame 64, which facilitates the squeezing and flattening of the pulp. Two sliding grooves are provided on the U-shaped plate 62. Two telescopic plates 63 slide in the two sliding grooves respectively. Springs are fixedly installed in both sliding grooves. One end of each spring is fixedly connected to the two telescopic plates 63 respectively. The shaping frame 64 is restored to its original state by the action of the two springs.

[0032] In this embodiment, both sides of the pressure plate 65 are provided with side ears and threaded rods 66 are threadedly connected. One end of each threaded rod 66 is rotatably connected to a limiting plate 67. The two limiting plates 67 are slidably connected to the pressure plate 65. The two limiting plates 67 are corresponding to the shaping frame 64 and are used to limit the pressure plate 65, thereby adjusting and controlling the thickness of the spread pulp. By rotating the threaded rod 66, the threaded rod 66 and the pressure plate 65 are threadedly driven, so that one end of the threaded rod 66 drives the limiting plate 7 to slide on the pressure plate 65.

[0033] In this embodiment, a fixing plate is fixedly connected to the shaping frame 64. The fixing plate is in contact with the pressure plate 65. A feed hose 7 is fixedly installed on the fixing plate. The feed hose 7 is adapted to the fixing plate and corresponds to the shaping frame 64, and is used to transport pulp.

[0034] In this embodiment, a solenoid valve 10 is provided on the feed hose 7, and the solenoid valve 10 is connected to the control panel 5. A sealing ring 2 is fixedly sleeved on the feed hose 7, and the outer wall of the sealing ring 2 is fixedly connected to the cover plate 4 to improve the sealing performance.

[0035] In this embodiment, a gas-liquid separator 8 and a vacuum pump 9 are provided on the base plate 1. A circular tube is sealed to the gas-liquid separator 8, and one end of the circular tube is sealed to the housing 2. One end of the vacuum pump 9 is sealed to the gas-liquid separator 8. Under the drive of the vacuum pump 9, a negative pressure is generated in the housing 2 and the cover plate 4. At the same time, the pulp is dewatered under the action of the negative pressure. Both the gas-liquid separator 8 and the vacuum pump 9 are connected to the control panel 5. A drain pipe is provided on the gas-liquid separator 8, and one end of the drain pipe is connected to a collection box for collecting the water separated by the gas-liquid separator.

[0036] Working principle: During use, the cylinder 61, vacuum pump 9, solenoid valve 10 and gas-liquid separator 8 are driven and controlled through the control panel 5;

[0037] First, the fabric is placed on the mesh plate 3. Then, the mesh plate 3 is inserted into the machine housing 2 and aligned with the shaping frame 64. Then, the cylinder 61 is activated. Driven by the cylinder 61, the U-shaped plate 62 and the pressure plate 65 move downward synchronously. At the same time, the U-shaped plate 62 drives the shaping frame 64 to move synchronously through the two telescopic plates 63. When the shaping frame 64 comes into contact with the mesh plate 3, the cylinder 61 is stopped. Through the interaction between the shaping frame 64 and the mesh plate 3, the fabric on the mesh plate 3 is held and fixed.

[0038] Then, the solenoid valve 10 is opened to allow a certain amount of pulp to be discharged into the shaping frame 64 through the feed hose 7. After that, the solenoid valve 10 is closed and the cylinder 61 is restarted. At this time, the cylinder 61 drives the pressure plate 65 to continue to move downward, and causes the two telescopic plates 63 to retract, and the two springs on the U-shaped plate 62 to be compressed. Then, the pressure plate 65 moves into the shaping frame 64. At this time, through the interaction between the shaping frame 64, the wire mesh 3 and the pressure plate 65, the pulp is evenly spread on the wire mesh 3.

[0039] At the same time, it also achieves the effect of squeezing the water in the pulp, thereby achieving the first step of dewatering the pulp; then, the gas-liquid separator 8 and vacuum pump 9 are started. Driven by vacuum pump 9, negative pressure is generated in the casing 2 and cover plate 4. Under the action of negative pressure, the pulp is dewatered a second time, improving the dewatering efficiency.

[0040] The technological advancements of this invention compared to existing technologies are as follows: the coordinated operation of various components enables the automatic and uniform spreading of pulp, improving convenience and product quality, while also offering a simpler structure and greater practicality.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
