Description

Technical Field

[0001] This invention relates to the field of packaging box recycling and processing technology, and more specifically, to a device for recycling and processing raw materials from colored packaging boxes. Background Technology

[0002] Colored packaging boxes refer to product packaging with multiple colors and patterns printed on the surface of paper or other materials. They utilize the visual impact of color to attract consumers' attention, convey brand information, and enhance the product's quality. Common processes include four-color offset printing, spot color printing, and post-processing such as lamination and hot stamping, which give the box surface a rich color layer and texture. They are widely used in retail packaging scenarios for various commodities such as food, cosmetics, gifts, and electronic products.

[0003] The raw materials for colored packaging boxes are mainly paper bases such as coated paper, gray paper, and coated whiteboard paper, supplemented by environmentally friendly printing materials such as water-based pulp and UV pulp. Some products also include surface treatment layers such as flocking, lamination, and hot stamping. In the processing stage, the colored patterns are completed by four-color offset printing or digital printing, and then formed by processes such as die-cutting, creasing, and mounting. The pulp waste liquid and waste generated in the production process need to be filtered, purified, stirred and prevented from settling through a special recycling device. The pulp can be recycled to reduce costs and VOC emissions. In the recycling stage, the paper base material is mainly recycled into recycled fibers through physical and chemical processes such as pulping, deinking, and bleaching, and reused to make packaging paperboard or filling materials. In the prior art, during the recycling process of colored packaging boxes, the attached printed layer on its surface will form a high-viscosity colored composite paste after being regenerated by hot melting or solvent. When the paste is left to stand, the resin binder in it will gel and solidify due to the decrease in temperature, and the remaining solid particles will settle and separate, which seriously affects the secondary production and recycling quality of waste packaging boxes. Summary of the Invention

[0007] Further, the T-shaped bracket is arranged on the outer side of the rotating rod through a bearing, the T-shaped bracket is located between the upper and lower bevel gears, the sleeve is sleeved on the outer side of the rotating rod, the rotating rod penetrates through the upper and lower bevel gears, and the right bevel gear is respectively meshed with the bevel gears on the upper and lower sides.

[0008] Further, the rotating rod penetrates through the rotating disk, the outer surface of the rotating disk is in sliding fit with the inner surface of the tank body, the rotating disk is arranged above the horizontal plane where the feeding hopper is located, so that the slurry input by the feeding hopper can fall unimpeded into the mixing space below the rotating disk, the right side of the lower end of the top cover is fixedly connected with a temperature sensor, the gas delivery pipe penetrates through the top cover, and the first through holes are arranged in an inclined manner.

[0009] Further, a disturbing assembly is arranged inside the tank body, and the disturbing assembly comprises a stirring blade fixedly connected to the bottom end of the rotating rod.

[0010] Further, a plurality of fixing plates are fixedly connected to the outer surface of the rotating rod, two second through holes are penetratingly opened on the surface of each fixing plate, two turbulence strips are fixedly connected to both the upper and lower sides of each fixing plate, and the turbulence strips are diamond-shaped.

[0011] Further, a scraping assembly is arranged inside the tank body, and the scraping assembly comprises a first scraper fixedly connected to the side of the fixing plate away from the rotating rod.

[0012] Further, a guide groove is opened on the other side of the first scraper, both the first scraper and the guide groove are arc-shaped, the side of the first scraper where the guide groove is opened is in sliding fit with the inner side wall of the tank body, and chamfers are arranged on both left and right sides of the end of the first scraper close to the fixing plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention guides the hot airflow to contact the slurry through the rotating disk, so that the slurry is heated. As the hot air forms a downward spiral diffusion swirling air field through the rotating first through hole, the contact area between the hot air and the slurry material is increased, avoiding the gel solidification of the slurry resin under low temperature conditions, thereby preventing the slurry from being scrapped and wasted due to low temperature.

[0016] (2) The present invention uses a fixed plate and a baffle strip to agitate the slurry, so that the slurry in the tank is always in a uniform suspension state.

Since the first scraper contacts the inner wall of the tank during rotation and scrapes off the adhering slurry, it prevents the slurry from adhering and remaining, and prevents the long-term accumulation of material from drying and deteriorating. At the same time, it allows all the slurry in the tank to participate in the circulation process, avoiding the local slurry from thickening due to solvent evaporation caused by long-term adhesion to the tank wall.

Detailed Description of the Embodiments

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; apparently, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 8 , a device for recycling and processing color packaging box materials comprises a discharge pipe 11 fixedly connected at the center of the lower side of a tank body 1, a feed hopper 12 fixedly connected on the left side of the outer surface of the tank body 1, a top cover 13 arranged on the upper side of the tank body 1, a controller 14 fixedly connected on the front side of the tank body 1, a heat supply component 2 arranged on both the inner and outer sides of the tank body 1, and the heat supply component 2 comprises a drive motor 21 fixedly connected on the upper side of the top cover 13; The output end of the drive motor 21 is fixedly connected with a rotating rod 22, a bevel gear set 23 is arranged inside the top cover 13, the bevel gear set 23 is composed of three bevel gears meshed in a triangular arrangement, wherein the upper bevel gear is fixedly connected to the outer side of the rotating rod 22, the lower bevel gear is fixedly connected with a sleeve 25, the outer side of the rotating rod 22 is sleeved with a T-shaped bracket 24, the right side of the right bevel gear is rotatably connected to the inner right side of the top cover 13, the left side of the right bevel gear is rotatably connected to the right side of the horizontal part of the T-shaped bracket 24, the bottom end of the sleeve 25 is fixedly connected with a rotating disc 26, a plurality of first through holes 27 are formed through the surface of the rotating disc 26, the left side of the upper end of the top cover 13 is fixedly connected with a gas delivery pipe 28, and the top end of the gas delivery pipe 28 is connected with an external gas supply equipment.

[0022] The T-shaped bracket 24 is arranged on the outer side of the rotating rod 22 through a bearing, the T-shaped bracket 24 is located between the upper and lower bevel gears, the sleeve 25 is sleeved on the outer side of the rotating rod 22, the rotating rod 22 penetrates through the upper and lower bevel gears, and the right bevel gear is meshed with the upper and lower bevel gears respectively.

[0023] The rotating rod 22 penetrates the rotating disk 26, the outer surface of the rotating disk 26 is in sliding contact with the inner surface of the tank body 1, and the rotating disk 26 is disposed above the horizontal plane where the feed hopper 12 is located, so that the slurry fed from the feed hopper 12 can fall unimpeded into the mixing space below the rotating disk 26. A temperature sensor 29 is fixedly connected to the right side of the lower end of the top cover 13, the gas delivery pipe 28 penetrates the top cover 13, and the first through holes 27 are formed in an inclined manner.

[0024] By adopting the above technical solution, after the slurry enters the interior of the tank body 1 through the feed hopper 12, the drive motor 21 acts as a power input source to transmit rotational torque to the rotating rod 22, and drives the bevel gear set 23 inside the top cover 13 to operate, so that the upper bevel gear rotates synchronously. Through the transmission link composed of three bevel gears meshed in a triangular arrangement, the unidirectional rotational power of the rotating rod 22 is split and direction-changed, so as to drive the sleeve 25 fixedly connected with the lower bevel gear to realize independent rotational motion in the opposite direction to the rotating rod 22. The T-shaped bracket 24 is mounted on the outer side of the rotating rod 22 in a limited manner via bearings, positioned between the upper and lower bevel gears, and provides stable lateral support for the right bevel gear. The sleeve 25 is sleeved outside the rotating rod 22 and penetrates the lower bevel gear, and drives the rotating disk 26 at the bottom to operate synchronously during the reverse rotation process. The plurality of first through holes 27 uniformly opened on the surface of the rotating disk 27 form an air distribution grid. The constant-temperature hot air fed by the external air supply equipment through the gas delivery pipe 28 first completes pre-mixing and temperature equalization in the cavity inside the top cover 13, then is uniformly distributed circumferentially into the internal space of the tank body 1 through the first through holes 27 on the rotating disk 26. At the same time, the temperature sensor 29 monitors the temperature in real time and transmits the signal to the controller 14, which can stably maintain the working temperature in the tank body 1 within a suitable range of 15°C to 35°C. When the slurry needs to be discharged, the slurry can be discharged out of the tank body 1 through the discharge pipe 11; It should be noted that the external air supply equipment feeds constant-temperature hot air through the gas delivery pipe 28. When the sleeve 25 drives the rotating disk 26 to rotate, the hot air is forced to pass through each of the inclined first through holes 27. With the reverse rotation of the rotating disk 26, the hot air passing through the orifices is imparted a resultant velocity of circumferential tangential velocity and downward axial velocity, thereby physically forcing the formation of a downward airflow field. Since the hot air forms a downward spirally diffusing swirling airflow field through the rotating first through holes 27, the contact area between the hot air and the slurry material is increased, preventing the binder in the slurry resin from gelling and solidifying in a low-temperature environment, and further avoiding the scrapping and waste of the slurry caused by excessively low temperature.

[0025] As shown in Figure 2 and Figures 6 to 8 , the interior of the tank body 1 is provided with a disturbance assembly 3, and the disturbance assembly 3 includes a stirring blade 31 fixedly connected to the bottom end of the rotating rod 22.

[0026] Multiple fixing plates 32 are fixedly connected to the outer surface of the rotating rod 22. Two second through holes 33 are opened through the surface of the fixing plate 32. Two baffle strips 34 are fixedly connected to the upper and lower sides of the fixing plate 32. The baffle strips 34 are diamond-shaped.

[0027] By adopting the above technical solution, the stirring blade 31 fixedly installed at the bottom of the rotating rod 22 is the first-stage disturbance unit. It rotates synchronously with the rotating rod 22 at high speed, forming an axially upward pushing flow at the bottom of the tank 1, which throws the slurry material deposited at the bottom of the tank upward. The multiple sets of fixed plates 32 equidistantly arranged on the outer surface of the rotating rod 22 are the second-stage disturbance carriers. Each set of fixed plates 32 has two through holes 33 on its surface, which allow the slurry passing through the plate to form multiple fine jets, breaking the large-scale circulation formed by the material in the tank and splitting the overall flow field into multiple small-scale turbulent regions. At the same time, the rhomboid shapes fixed symmetrically on the upper and lower sides of the fixed plates 32 The turbulence strip 34 is the third-level turbulence unit. As the rhomboid special contour rotates with the fixed plate 32, its windward and leeward sides exert shearing and diversion effects on the high-viscosity slurry, respectively. This forms a local turbulent vortex in the area behind the turbulence strip, thereby breaking up the clumps of components in the slurry by mechanical shearing force, keeping the material components in uniform suspension. Due to the synergistic effect of the multi-level turbulence structure, the slurry in the tank 1 can always be kept in a uniform suspension state, avoiding the stratification phenomenon that occurs when pigment particles settle. This can achieve uniformity and stability of the slurry system, while increasing the contact area between the slurry and the hot airflow, reducing the phenomenon of slurry coagulation.

[0028] like Figure 2 , Figure 6 and Figure 8 As shown, the inside of the tank 1 is provided with a scraping assembly 4, which includes a first scraper 41 fixedly connected to the side of the fixed plate 32 away from the rotating rod 22.

[0029] A guide groove 42 is provided on the other side of the first scraper 41. Both the first scraper 41 and the guide groove 42 are arc-shaped. The side of the first scraper 41 with the guide groove 42 slides against the inner wall of the tank body 1. Chamfers are provided on both the left and right sides of the first scraper 41 near the fixed plate 32.

[0030] By adopting the above technical solution, multiple sets of first scrapers 41 are rigidly connected to the rotating rod 22 through the fixed plate 32 and rotate 360° around the rotating rod 22. The first scraper 41 has an arc-shaped structure, and its arc-shaped contour is completely matched with the cylindrical surface of the inner wall of the tank 1. The guide groove 42 with the same arc is opened on the side of the scraper. During the process of the scraper sliding along the inner wall, the high viscosity slurry adhering to the tank wall can be continuously introduced into the guide groove 42. With the help of the centrifugal force generated by the rotation, the slurry is thrown out from both ends of the guide groove 42 and flows back to the mainstream area in the center of the tank 1. The chamfered structure at both ends of the first scraper 41 near the fixed plate 32 can significantly reduce the fluid resistance encountered by the scraper during rotation, and prevent high-viscosity slurry from forming rigid resistance on the scraper. At the same time, the chamfered part can shear the protruding material on the tank wall, peeling off the slurry layer that has been attached for a long time and has initially formed a skin from the tank wall. Since the first scraper 41 contacts the inner wall of the tank 1 during rotation and scrapes off the adhered slurry, it prevents the slurry from adhering and remaining, and prevents the long-term accumulation of material from drying and deteriorating. At the same time, it can allow all the slurry in the tank 1 to participate in the circulation process, and prevent the local slurry from thickening due to solvent evaporation caused by long-term adhesion to the tank wall.

[0031] like Figure 6 and Figure 8 As shown, the tank body 1 is equipped with an anti-sinking component 5, which includes a fixing block 51 fixedly connected to the lower side of the first scraper 41.

[0032] A second scraper 52 is fixedly connected to the side of the fixed block 51 near the rotating rod 22. The outer surface of the second scraper 52 is chamfered. The lower side of the second scraper 52 slides and fits against the lower inner side of the tank body 1. The second scraper 52 is located below the stirring blade 31.

[0033] By adopting the above technical solution, the fixed block 51 serves as a connecting carrier, integrating the second scraper 52 with the first scraper 41. It rotates synchronously with the first scraper 41 in the circumferential direction. The lower surface of the second scraper 52 completely slides and adheres to the inner bottom surface of the tank 1, forming a continuous scraping operation across the entire tank bottom during rotation. This shovels up any slurry material that is about to deposit or has already deposited at the tank bottom in real time, preventing the formation of an unevenly thick sediment layer at the bottom. The second scraper 52 is positioned directly below the stirring blade 31, allowing the slurry to be directly incorporated into the working range of the stirring blade 31. With the axial pushing flow generated by the stirring blade 31, it is rapidly transported upwards to the upper part of the tank 1, reintegrating into the overall circulating flow field. The chamfered structure on the edge of the second scraper 52 reduces the frictional resistance with the bottom of the tank during the scraping process. At the same time, it shears and breaks down the hard slurry clumps, breaking down large clumps into smaller particles that disperse with the fluid. This prevents large particles from clogging the bottom discharge pipe 11 and avoids the problems of sedimentation and clumping that occur when the slurry is left to stand for a long time. It ensures the uniformity of the overall slurry system and allows the recovered slurry to be directly recycled into production without additional grinding and dispersion treatment.

[0034] Working principle: The drive motor 21 drives the three bevel gear set 23 with a triangular meshing through the rotating rod 22. After the power is diverted and reversed, the drive sleeve 25 drives the rotating disk 26 to rotate in the opposite direction. The constant temperature hot air delivered by the external air supply equipment enters the top cover 13 chamber through the air supply pipe 28 and is premixed. It forms a circumferentially uniform downward spiral diffusion swirling air field through the first through hole 27 on the rotating disk 26. With the help of the temperature sensor 29 and the controller 14, the temperature inside the tank is stably maintained at 15℃-35℃ to prevent the slurry binder from gelling and solidifying at low temperatures. The rotating rod 22 drives the bottom stirring blades 31 to form an axial upward pushing flow, throwing the slurry deposited at the bottom of the tank upward. The fixed plate 32 on the outside of the rotating rod 22 rotates with the shaft. The second through hole 33 on the plate surface splits the material into multiple fine jets to break the large-scale circulation. The diamond-shaped baffle strips 34 on both sides of the plate alternately form positive and negative flow patterns as they rotate. In the negative pressure zone, relying on the mechanical shearing force of the rhomboid edge blades and the local turbulent vortex formed behind the turbulent strips, the clumps of pigment particles and solid particles in the slurry are broken up. The multi-level disturbance synergistic effect keeps the slurry in a uniform suspension state. The arc-shaped first scraper 41, which is fixed to the fixed plate 32, rotates circumferentially with the axis. When it slides against the inner wall of the tank 1, it guides the high-viscosity slurry adhering to the wall surface into the guide groove 42. With the help of centrifugal force, the slurry is thrown back to the mainstream area of ​​the tank 1. The chamfer at the end of the scraper can reduce fluid resistance and at the same time shear off the dried and crusted material on the tank wall. The second scraper 52, which is connected to the bottom of the first scraper 41 through the fixed block 51, follows and scrapes the inner bottom surface of the tank 1. It scoops up the deposited material in real time and sends it directly into the action range of the stirring blade 31 below. It is quickly transported to the upper part of the tank 1 through axial flow to re-enter the circulation. The chamfer at the edge of the scraper can break up the hard slurry clumps.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
