Description

Technical Field

[0001] This utility model relates to the field of sizing agent emulsification technology, specifically a surface sizing agent emulsification device. Background Technology

[0002] Sizing agents are papermaking additives primarily used to improve the paper's resistance to water, oil, and printing inks. They also enhance the paper's smoothness, hydrophobicity, and printability. Sizing agents can be broadly classified into in-pulp sizing agents and surface sizing agents. Surface sizing agents generally use anionic polymers and are applied to the surface of paper or paperboard after the paper sheet is formed. They are mainly used to improve the smoothness of the paper surface, reduce porosity, and prevent surface fuzzing and shedding. Common surface sizing agents include starch, polyvinyl alcohol (PVA), paraffin emulsion, animal glue, and carboxymethyl cellulose. Sizing agents need to be emulsified during the production process, mainly to improve their dispersibility, wetting properties, and stability, thereby enhancing the sizing effect and paper quality. The emulsification process includes using equipment to filter the sizing agent.

[0003] Existing sizing agent emulsification equipment typically filters the agent using a static filter screen. This screen is prone to clogging when filtering thick sizing agents, significantly reducing the filtration efficiency. Furthermore, the filtration process involves adding sizing agent to only one location on the filter screen, resulting in waste in other areas and further impacting filtration efficiency.

[0004] Therefore, those skilled in the art have provided a surface sizing agent emulsification device to solve the problems mentioned in the background art. Utility Model Content

By setting a movable mechanism, the iron screen can be moved up and down during the filtration process. The movable iron screen can accelerate the filtration efficiency of the sizing agent, greatly improving the device's sieving efficiency. Secondly, by setting a movable mechanism, the sizing agent can be automatically poured to different positions on the iron screen, avoiding the accumulation of sizing agent in one place and affecting the filtration efficiency, further improving the device's filtration efficiency. At the same time, the sizing agent can be stirred before pouring, facilitating subsequent filtration work, thereby solving the problems mentioned in the background art.

[0020] Please see Figures 1-4 In this embodiment of the present invention, a surface sizing agent emulsification device includes an emulsification device body 1, a discharge port 2 at the lower end of the emulsification device body 1, and four support columns 3 fixedly connected to the lower end of the discharge port 2. The four support columns 3 can support and fix the entire emulsification device. A movable frame 4 is slidably connected inside the emulsification device body 1. The movable frame 4 can move up and down based on the interior of the emulsification device body 1. An iron screen 5 is provided inside the movable frame 4. The emulsified sizing agent can be screened through the iron screen 5, mainly to remove impurities and incompletely emulsified particles to ensure the purity and stability of the final product.

[0021] Two U-shaped rods 6 are slidably connected to the main body 1 of the emulsifying equipment. One end of the two U-shaped rods 6 is located inside the main body 1 of the emulsifying equipment and is fixedly connected to the movable frame 4. A movable rod 7 is slidably connected to the outer wall of the main body 1 of the emulsifying equipment. The other end of the two U-shaped rods 6 is fixedly connected to the movable rod 7. A limit post 8 is fixedly connected to the movable rod 7. A positioning plate 11 is fixedly connected to the outer wall of the main body 1 of the emulsifying equipment. A drive motor 12 is provided on the positioning plate 11. A second movable bar 10 is connected to the output shaft of the drive motor 12. The limit post 8 and the second movable bar 10 are connected by a first movable bar 9. Both ends of the first movable bar 9 are rotatably set with the limit post 8 and the second movable bar 10. When the drive motor 12 is working, it can drive the second movable bar 10 to rotate, thereby driving the limit post 8 and the movable rod 7 to move up and down through the first movable bar 9. Then, the movable frame 4 is driven to move up and down reciprocally through the U-shaped rods 6, thereby accelerating the filtration efficiency of the sizing agent by the iron screen 5.

[0022] The main body 1 of the emulsification equipment has a sliding connection to a movable box 14. The upper end of the movable box 14 has a feed inlet 15, which is connected to the outside through a flexible tube to facilitate the delivery of the sizing agent to be screened into the movable box 14. The lower end of the movable box 14 has a drop outlet 16, through which the sizing agent inside the movable box 14 can fall and finally fall onto the iron screen 5 for screening. Both ends of the movable box 14 are rotatably connected to drive gears 18, and a stirring mechanism is connected between the two drive gears 18. The side wall of the main body 1 of the emulsification equipment has a toothed groove 19. When the movable box 14 moves, the drive gears 18 can drive the stirring mechanism to rotate under the action of the toothed groove 19, thereby stirring the sizing agent and facilitating the subsequent filtration work.

[0023] A reciprocating screw 13 is rotatably connected to the main body 1 of the emulsifying equipment. One end of the reciprocating screw 13 passes through the second movable bar 10 and is connected to the output shaft of the drive motor 12. When the drive motor 12 is working, it can drive the reciprocating screw 13 to rotate. A movable block 17 is fixedly connected to the upper end of the moving box 14. The movable block 17 and the reciprocating screw 13 are connected by a threaded sleeve. When the reciprocating screw 13 rotates, it can move the moving box 14 based on the main body 1 of the emulsifying equipment.

[0024] The working principle of this utility model is as follows: When the device is needed to filter the sizing agent, the sizing agent to be screened is first conveyed to the inside of the moving box 14 through the feed port 15. At any time, the sizing agent can fall onto the iron screen 5 through the drop port 16 for filtration. After filtration, the sizing agent can be removed from the equipment through the discharge port 2. During the screening process, the drive motor 12 works, which drives the reciprocating screw 13 to rotate. This drives the moving box 14 to move back and forth through the movable block 17, so that the sizing agent can be poured onto different positions of the iron screen 5, avoiding the accumulation of sizing agent in one place and affecting the filtration efficiency. During the movement of the moving box 14, under the action of the tooth groove 19, the drive gear 18 can drive the stirring mechanism to rotate, realize the stirring of the sizing agent, and facilitate the subsequent filtration work. When the drive motor 12 works, it can also drive the second movable bar 10 to rotate, which drives the limit column 8 and the movable rod 7 to move up and down through the first movable bar 9. Then, the movable frame 4 moves up and down reciprocally through the U-shaped rod 6, thereby accelerating the filtration efficiency of the sizing agent by the iron screen 5.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
