Description

[0002] In the production process of medical cold sealing paper, the treatment of broken paper is a crucial link. Due to its special use, medical cold sealing paper has extremely high requirements for its cleanliness. However, in the existing production process, broken paper is often accumulated for a long time and then treated uniformly. This treatment method has many shortcomings, the most notable of which is that dust easily accumulates on the surface of broken paper.

[0003] Broken paper accumulated over a long period of time will inevitably absorb a large amount of dust and impurities due to its exposure to the air. These dust and impurities will not only affect the reuse of broken paper, but also have a negative impact on the subsequent pulp production and paper quality. In the production of medical cold seal paper, any tiny impurities may lead to a decline in product quality, thus failing to meet the strict requirements of the medical industry.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] High-efficiency dust removal and crushing: The present invention can efficiently process the broken paper in the process of making medical cold-sealed paper. Under the action of the stepped mesh plate, the broken paper slows down the falling speed and increases the vibration, which is conducive to the floating of dust and subsequent electrostatic precipitator treatment. The electrostatic precipitator plate can efficiently absorb the dust through the mesh, while the crushing teeth on the crushing roller and the crushing cavity can cut or grind the broken paper, which provides convenience for subsequent pulp production.

[0017] Automatic control: The left and right chambers in the device are continuously opened and closed under the action of the elliptical crushing roller and the elastic guide sleeve assembly, realizing the intermittent loading and unloading of broken paper. This automatic control method not only improves work efficiency, but also ensures that the broken paper is fully crushed. At the same time, the opening and closing shaking of the screen helps to remove the dust adhering to the broken paper, further enhancing the dust removal effect.

[0018] Easy maintenance and cleaning: The design of the device takes into account the need for easy maintenance and cleaning. The dust discharge port on the bottom plate is convenient for removing accumulated dust; the opening and closing movement of the left and right chambers can scrape the bottom plate, which helps to discharge the dust accumulated on the upper side of the bottom plate; the water mist nozzle can continuously spray mist water to form a water film on the surface of the electrostatic precipitator plate, which not only enhances the dust removal ability, but also facilitates the removal of dust under the action of the screen plate.

[0019] Optimized pulping process: The design of the mixing and stirring mechanism allows the shredded broken paper to be evenly mixed with other raw materials and ingredients, and then made into pulp after adding water. The two sets of stirring blades in the shape of an auger and symmetrically arranged can enhance the stirring effect and ensure the uniformity and quality of the pulp. This optimized process not only improves the efficiency of pulping, but also reduces production costs.

[0020] Improve resource utilization: Through the processing of this device, broken paper can be effectively utilized, reducing resource waste. At the same time, the device is also suitable for processing other types of waste paper or fiber materials, further improving its application scope and resource utilization.

[0036] like Figure 4 and 6 As shown, a water mist nozzle 223 is fixedly installed on the lower side of the upper part of the mesh plate 26 and above the electrostatic precipitator plate 213.

[0037] like Figure 4 and 7 As shown, the elastic guide sleeve assembly 215 includes a slide rod 2151 fixedly arranged on the outside of the left cavity 281 and the right cavity 282, and a slide sleeve 2152 is fixedly arranged at the position corresponding to the slide rod 2151 inside the two sides of the box body 21, and the outer end of the slide rod 2151 is slidably arranged inside the slide sleeve 2152, and a return spring 2153 is arranged on the outside of the slide rod 2151 and between the inner side of the box body 21 and the outside of the left cavity 281 and the right cavity 282.

[0038] like Figure 1 and 2 As shown, the mixing and stirring mechanism 1 includes a bottom bracket 11, a mixing pool 12 is fixedly arranged on the upper side of the bottom bracket 11, a stirring shaft 13 is rotatably arranged inside the mixing pool 12, a stirring blade 14 is fixedly arranged on the stirring shaft 13, a stirring motor 15 is fixedly arranged on the front end side of the bottom bracket 11, and the stirring motor 15 is connected to the stirring shaft 13 through a reducer 16, a fixing plate 17 is fixedly arranged on the upper side of the front end of the mixing pool 12, a dust removal and crushing mechanism 2 is fixedly arranged on the upper side of the fixing plate 17, and a mixing outlet 18 is arranged on the lower side of the end of the mixing pool 12. Two groups of stirring shafts 13 are arranged, and the stirring blades 14 are auger blades, and the spiral directions of the auger blades on different stirring shafts 13 are opposite.

[0039] The box body 21 of the present invention serves as the main part of the dust removal and pulverization mechanism 2, and its structure is sturdy and can bear various workloads. A feed port 22 is provided at the upper end of the box body for receiving dry broken paper to be processed. A bottom plate 23 is fixed at the lower end, and a discharge port 24 is provided on the bottom plate 23 for discharging the broken paper after dust removal and pulverization. At the same time, dust discharge ports 224 are also provided on both sides of the box body to facilitate the removal of accumulated dust. The quadrilateral guide block 25 is fixed at the middle position of the inner side of the box body 21, and is used to guide the flow direction of the broken paper to ensure that the broken paper can smoothly enter the subsequent pulverization chamber 28. The mesh plate 26 is designed in a stepped shape and is obliquely arranged on the outer side of the lower side of the quadrilateral guide block 25. A feeding channel 27 is formed between the mesh plate 26 and the quadrilateral guide block 25, which is used to transport the broken paper from the feed port 22 to the pulverization chamber 28. The stepped design can slow down the speed of broken paper falling and increase the vibration of broken paper when rolling or sliding, which is beneficial to the floating of dust and subsequent electrostatic precipitator treatment (the flat screen plate 26 easily causes broken paper to block the mesh of the screen plate 26). The electrostatic precipitator plate 213 is arranged inside the box 21, on the outside of the screen plate 26. The electrostatic precipitator plate 213 is arranged parallel to the lower side of the quadrilateral guide block 25, and can adsorb dust through the mesh of the screen plate 26. A guide rod 222 is fixed to the lower side of the electrostatic precipitator plate 213, and the lower end of the guide rod is slidably connected to the outer side of the upper part of the left and right cavities. The components such as the slide 214, the slide seat 216, the moving block 217, the compression spring 220, etc. together constitute the sliding adjustment mechanism of the screen plate 26. Through the cooperation of the slide 214 and the slide seat 216, and the elastic force of the compression spring 220, the screen plate 26 can slide horizontally in the box 21, thereby realizing the opening and closing control of the feeding channel.

[0040] like Figure 1-8As shown, the working process of the present invention is as follows: dry broken paper is put into the box body 21 from the feed port 22, and enters the crushing chamber 28 through the feeding channel 27. The stepped mesh plate 26 can slow down the time for the broken paper to fall, increase the vibration of the broken paper when rolling or sliding on the steps, and increase the floating space of dust (when the mesh plate 26 is flat, the broken paper is easy to block the mesh holes of the mesh plate 26), so that the electrostatic precipitator plate 213 can absorb the dust through the mesh holes of the mesh plate 26. After the dust is removed, the broken paper enters the crushing chamber 28 and is sheared or ground by the crushing roller 211 and the crushing teeth on the crushing chamber 28, and then enters the immersion mixing and stirring mechanism 1 to be mixed with other raw materials and ingredients and water is added to make paper pulp. The pulverizing chamber 28 is divided into a left chamber 281 and a right chamber 282. Under the action of the elliptical pulverizing roller 211 and the elastic guide sleeve assembly 215, the left chamber 281 and the right chamber 282 are continuously opened and closed, thereby driving the opening and closing of the two screen plates 26, controlling the closing and opening of the feeding channel 27, and the closing and opening of the pulverizing feed port 29 and the pulverizing discharge port 210, thereby realizing the intermittent loading and unloading of broken paper. The continuous opening and closing and shaking of the screen plates 26 can drive the shaking of the broken paper inside the feeding channel 27, thereby facilitating the dust adhering to the broken paper to separate from the broken paper, and facilitating the dust removal of the electrostatic precipitator plate 213. When the left chamber 281 and the right chamber 282 are opened outward, the screen plates 26 are first driven to open to both sides. When the screen plates 26 contact the electrostatic precipitator plate, they begin to stop moving, while the left chamber 281 and the right chamber 282 continue to open to both sides. At this time, the upper sides of the left chamber 281 and the right chamber 282 are opened. The left cavity 281 and the right cavity 282 start to contact with the lower end of the guide rod 222, so that the left cavity 281 and the right cavity 282 drive the electrostatic precipitator plate 213 to slide upward along the guide plate 221 through the guide rod 22, so that the two sides of the stepped mesh plate 26 can scrape the inner surface of the dust removal plate 213, so that the dust adsorbed on the dust removal plate 213 falls onto the bottom plate 23 at the bottom of the box body 21. When the left cavity 281 and the right cavity 282 move inward, the electrostatic precipitator plate 213 Under the influence of gravity, the screen plate 26 moves inward and closes again. The left cavity 281 and the right cavity 282 that are constantly opened and closed can scrape the upper side of the bottom plate 23, which is conducive to the discharge of dust accumulated on the upper side of the bottom plate 23 from the dust discharge port 224. The water mist nozzle 223 can continuously spray mist water, and the mist water forms a water film on the surface of the electrostatic precipitator plate 213, which is conducive to the dust removal ability of the electrostatic precipitator plate and is conducive to clearing dust under the action of the screen plate 26. The function of the mixing and stirring mechanism 1 is to make pulp from the broken paper after pulverization. Appropriate water and other raw materials are added according to requirements. The stirring blades 14 rotate and stir to form pulp under the drive of the stirring motor 15. The two groups of stirring blades 14 in the shape of an auger and symmetrically arranged are conducive to increasing the stirring effect and the discharge of the pulp after it is made.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
