Description

Technical Field

[0001] This invention relates to the field of high-efficiency granulation technology for red lead powder, and more particularly to a high-efficiency granulation device for red lead powder. Background Technology

[0002] Red lead is an additive used in the manufacture of lead-acid batteries. Compared with other similar additives, red lead is the best choice for battery additives due to its high oxidation content, which cannot be replaced by other additives. In the red lead granulation process, the factory directly sprays water mist and rotates the rollers to drive the initially aggregated particles to continuously expand their volume during the rolling process until they reach the production standard. In addition, iron balls are added during the process to improve the appearance of the red lead particles by colliding with them.

[0003] Chinese patent CN216678136U discloses a granulation device for red lead granulation, including a slant disc rotating assembly, a granulation disc support mechanism, and a dynamic tilting mechanism for the granulation disc. The slant disc rotating assembly is mounted on the granulation disc support mechanism, and the dynamic tilting mechanism for the granulation disc is mounted on the granulation disc support mechanism.

[0004] In existing technologies, a large amount of red lead powder is added to the roller at once and mixed with water mist to form pellets. However, this process is prone to situations where the powder is not completely wetted. The relatively dry powder is trapped inside the pellets, which affects the overall bonding strength of the pellets and leads to breakage during subsequent processing or transfer packaging. In addition, due to the differences in the structure of red lead powder, some powders have poor water absorption and low adhesion, making it difficult for them to bond with the pellets. Furthermore, some small spherical pellets have smooth and dense surfaces, making it difficult for water mist to adhere to and penetrate them, resulting in slow growth during the pelletizing process. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-efficiency granulation device for red lead powder. By combining the granulation mechanism with the shaping mechanism, the red lead powder and water mist are fully combined, and the adhesion of the smooth particles to the surface is enhanced. This solves the problems of reduced strength caused by dry powder easily encapsulating in red lead particles and slow growth of some smooth particles.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency granulation device for red lead powder, comprising a granulation mechanism mounted on a frame, a sieving mechanism mounted on the granulation mechanism and located at the outer circumference of the granulation mechanism, and a shaping mechanism mounted on the sieving mechanism and located below the granulation mechanism. The shaping mechanism includes a kneading component disposed on the screening mechanism for moving and changing the shape of the red lead particles, a limiting component disposed on the screening mechanism for controlling the red lead particles in the processing position, a vibration component disposed on the screening mechanism for driving the red lead particles to be evenly distributed in the processing position, and a shaping component disposed on the screening mechanism for forming grooves on the red lead particles and filling them with adhesive in conjunction with the kneading component. After the granulation process begins, the red lead powder is transformed from powder to granules under the action of the granulation mechanism. After a period of time, the raw material is discharged to the screening mechanism, which screens out the red lead granules that meet the production requirements and discharges the small granules and the remaining red lead powder. The small granules undergo shape change and binder filling in the shaping mechanism, and then combine with the remaining red lead powder and are sent back to the granulation mechanism to continue to increase in volume.

[0007] Furthermore, the rolling mechanism includes a cloth assembly mounted on the frame for improving the binding effect of red lead powder and water mist, a separation assembly mounted on the cloth assembly for timely collection and processing of excessively large red lead, a cutting assembly mounted on the separation assembly for cutting the processed raw material into small pieces, and an output assembly mounted on the frame for outputting the rolled raw material.

[0008] Furthermore, the fabric assembly includes a first motor connected to the frame, a mounting plate connected to the output end of the first motor and connected to a roller, a U-shaped frame connected to the frame, a plurality of nozzle frames and hoppers connected to the U-shaped frame and arranged alternately, a second motor connected to the U-shaped frame and connected to a cylindrical cam at its output end, and a driven member connected to the nozzle frame and whose end cooperates with the cylindrical cam to drive the nozzle frame and hopper to swing.

[0009] Furthermore, the separation assembly includes a toothed plate connected to the mounting plate via a first torsion spring, a collection box connected to the U-shaped frame, two sets of extrusion rollers connected to the collection box, two mating gears respectively connected to the extrusion rollers and meshing with each other, and a first belt drive component with its two ends respectively connected to the output end of the second motor and the extrusion roller on the same side. The cutting assembly includes two sets of cutting plates connected to the bottom of the collection box, a drive gear connected to the collection box, two sets of first racks connected to the cutting plates and meshing with the drive gears, and a drive rack connected to the nozzle frame and meshing with the drive gears.

[0010] Furthermore, the output component includes a third motor connected to the frame, an arc-shaped guide rail connected to the frame, a slide rod connected to the arc-shaped guide rail, a drive rod connected to the output end of the third motor and one end sleeved outside the slide rod, a blocking ring connected to the end of the slide rod and located inside the roller, a first baffle connected to the blocking ring, and a second baffle connected to the first baffle via a first telescopic member.

[0011] Furthermore, the screening mechanism includes a first screening component mounted on the mounting plate for screening out qualified red lead and recovering iron balls, and a second screening component mounted on the frame for secondary screening of the raw materials and recycling the raw materials into the fabric assembly.

[0012] Furthermore, the first screening assembly includes a rotary screen frame connected to the mounting plate, an electromagnetic module connected to the side of the rotary screen frame, a first guide frame connected to the frame with its two ends located at the rotary screen frame and the drum respectively, and a flap connected to the first guide frame by a second torsion spring.

[0013] Furthermore, the second screening assembly includes an annular frame connected to the frame, a transfer frame connected to the annular frame, a second guide frame connected to the frame and communicating with the first guide frame, a fourth motor connected to the frame, a drive wheel connected to the output end of the fourth motor and used to drive the annular frame, and a screen frame connected to the frame via a second telescopic member.

[0014] Furthermore, the kneading assembly includes a fifth motor connected to the screen frame, a sprocket and chain drive component with its two ends connected to the screen frame and the output end of the fifth motor respectively, a fixed frame connected to the screen frame and connected to the sprocket and chain drive component, and a kneading plate connected to the fixed frame. The limiting assembly includes a limiting plate extending through the bottom of the screen frame, two sets of coaxial gear pairs connected to the screen frame, two sets of second racks connected to the limiting plate via a cooperating rod and respectively meshing with the two sets of coaxial gears, and a third rack connected to the fixed frame and meshing with the coaxial gears. The vibration assembly includes a trigger plate connected to the end of the screen frame and multiple sets of levers connected to the rotary screen frame for moving the trigger plate.

[0015] Furthermore, the shaping assembly includes multiple shaping frames passing through the screen frame, a support plate connected to the multiple shaping frames and with multiple right-angle frames connected to its top, multiple sets of cone holes passing through the shaping frames and connected to the shaping frames via springs, a drive shaft passing through the screen frame, a second belt drive component with its two ends connected to the drive shaft and the output end of the fifth motor respectively, a disc-shaped cam connected to the drive shaft and used to drive the support plate to move up and down, and multiple sets of glue injection frames connected to the screen frame and corresponding to the shaping frames.

[0016] The beneficial effects of this invention are as follows: (1) The present invention uses a shaping mechanism to squeeze and knead spherical particles that have not reached the qualified size and have originally smooth surfaces into capsules, and forms grooves on the surface that are easy for adhesive to adhere to. Thus, the adhesive is used to combine the red lead powder with poor water absorption with the shaped particles, forming grooves on the surface of the particles, increasing their water mist adhesion ability, and promoting their continued growth in volume.

[0017] (2) By setting the cloth component in the granulation mechanism, the present invention enables the originally separated red lead powder and water mist to first combine and then integrate with the particles in the roller, thereby ensuring that the moisture content of the red lead particles can ensure that there is no dry powder embedded inside, and at the same time, it will not put too much pressure on subsequent drying, thus ensuring the integrity of the red lead particles during production and transportation.

[0018] (3) By setting the output component, the present invention is located at the upper position during the rolling process of red lead particles. The powder attached to the wall is dynamically scraped off by mechanical bonding, so that the separated powder falls back to the particle bed under the action of gravity, realizing the closed-loop reuse of raw materials and significantly improving the utilization rate of raw materials. In addition, when the particles need to be output, they are rotated to the lower position and the roller is rotated in a directional manner to form a forced unloading channel, realizing the efficient and controllable output of particles and improving the operability of the device.

[0019] (4) By setting up a screening mechanism, the present invention can quickly recover iron balls by magnetic attraction while screening qualified red lead particles. After the shaping mechanism is completed, the shaped particles are mixed with powder with poor water absorption and sent back to the drum to continue growing, thereby improving the utilization rate of raw materials and production efficiency.

[0020] In summary, the present invention has the advantages of high integrity of red lead particles, full utilization of raw materials, and high production efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] Example 1 like Figures 1 to 2 and Figure 5 as well as Figures 7 to 9 As shown, this embodiment provides a high-efficiency granulation device for red lead powder, including a granulation mechanism 1 mounted on a frame 100, a screening mechanism 2 mounted on the granulation mechanism 1 and located on the outer circumference of the granulation mechanism 1, and a shaping mechanism 3 mounted on the screening mechanism 2 and located below the granulation mechanism 1. The shaping mechanism 3 includes a kneading component 31 disposed on the screening mechanism 2 and used to move and change the shape of the red lead particles; a limiting component 32 disposed on the screening mechanism 2 and used to control the red lead particles to be processed; a vibration component 33 disposed on the screening mechanism 2 and used to drive the red lead particles to be evenly distributed at the processing position; and a shaping component 34 disposed on the screening mechanism 2 and used to cooperate with the kneading component 31 to form grooves on the red lead particles and fill them with adhesive. After the granulation process begins, the red lead powder is transformed from powder to granules under the action of the granulation mechanism 1. After a period of time, the raw material is discharged to the screening mechanism 2, which screens out the red lead granules that meet the production requirements and discharges the small granules and the remaining red lead powder. The small granules undergo shape change and binder filling in the shaping mechanism 3, and then combine with the remaining red lead powder and are sent back to the granulation mechanism 1 to continue to increase in volume.

[0025] In this embodiment, by setting the rolling mechanism 1 in conjunction with the shaping mechanism 3, the red lead powder and mist are fully combined and the adhesion of the smooth particle surface is enhanced, which solves the problems of easy dry powder encapsulation in red lead particles leading to reduced strength and slow growth of some smooth particles.

[0026] Furthermore, such as Figures 1 to 4 As shown, the rolling mechanism 1 includes a cloth assembly 11 mounted on the frame 100 for improving the binding effect of red lead powder and water mist, a separation assembly 12 mounted on the cloth assembly 11 for timely collection and processing of excessively large red lead, a cutting assembly 13 mounted on the separation assembly 12 for cutting the processed raw material into small pieces, and an output assembly 14 mounted on the frame 100 for outputting the rolled raw material.

[0027] In this embodiment, by setting up a fabric assembly 11, a separation assembly 12, a cutting assembly 13, and an output assembly 14, the particles are controlled in real time throughout the entire granulation process, including ensuring the moisture content of the particles, controlling the particle size, and making full use of the raw materials.

[0028] In detail, at the start of the granulation process, the fabric assembly 11 combines water mist and red lead powder through alternating mixing. After the raw material falls, it forms a preliminary aggregate under the collision of the iron ball. Subsequently, it grows continuously during granulation, increasing its volume. During the granulation process, the separation assembly 12 passes over the raw material, collects some particles that grow too fast, and squeezes them into strips to cooperate with the cutting assembly 13 to reform small particles. After granulation is completed, the particles are quickly output through the output assembly 14.

[0029] Furthermore, such as Figures 1 to 3 As shown, the fabric assembly 11 includes a first motor 111 connected to the frame 100, a mounting plate 113 connected to the output end of the first motor 111 and connected to a roller 112, a U-shaped frame 114 connected to the frame 100, a plurality of nozzle frames 115 and hoppers 116 connected to the U-shaped frame 114 and alternately arranged, a second motor 118 connected to the U-shaped frame 114 and connected to a cylindrical cam 117 at its output end, and a follower 119 connected to the nozzle frame 115 and whose end cooperates with the cylindrical cam 117 to drive the nozzle frame 115 and hopper 116 to swing.

[0030] In this embodiment, by setting the cloth component 11 in the granulation mechanism 1, the originally separated red lead powder and water mist can first combine and then integrate with the particles in the roller 112. This ensures that the moisture content of the red lead particles can be guaranteed so that there is no dry powder embedded inside, and at the same time, it will not put too much pressure on the subsequent drying, thus ensuring the integrity of the red lead particles during production and transportation.

[0031] In detail, at the beginning of the pelletizing process, the first motor 111 drives the roller 112 to rotate through the mounting plate 113, while the second motor 118 drives the cylindrical cam 117 to rotate. Due to the cooperation between the follower 119 and the cylindrical cam 117, the follower 119 drives multiple interconnected nozzle frames 115 and hoppers 116 to swing back and forth on the U-shaped frame 114. Red lead powder and water mist fall alternately, and they combine more fully. After falling, they gradually form granules with the action of the roller 112 and the iron ball.

[0032] It should be noted that the nozzle frame 115 has an outermost enclosed structure, with the water mist direction offset inward to guide the red lead powder downward and prevent leakage.

[0033] Furthermore, such as Figures 1 to 3 As shown, the separation assembly 12 includes a toothed plate 122 connected to the mounting plate 113 via a first torsion spring 121, a collection box 123 connected to the U-shaped frame 114, two sets of extrusion rollers 124 connected to the collection box 123, two mating gears 125 respectively connected to the extrusion rollers 124 and meshing with each other, and a first belt drive component 126 with both ends connected to the output end of the second motor 118 and the extrusion roller 124 on the same side, respectively. The cutting assembly 13 includes two sets of cutting plates 131 connected to the bottom of the collection box 123, a drive gear 132 connected to the collection box 123, two sets of first racks 133 connected to the cutting plates 131 and meshing with the drive gears 132, and a drive rack 134 connected to the nozzle frame 115 and meshing with the drive gears 132.

[0034] In this embodiment, by setting the separation component 12 and the cutting component 13, the particles are screened multiple times during the granulation process. The excessively large red lead particles are collected in time, broken down into smaller particles, and put back into the granulation process. This effectively controls the size of qualified red lead at the output of raw materials to be basically consistent, which is conducive to the uniformity of subsequent drying work, reduces energy consumption, and ensures thorough drying.

[0035] In detail, during the rotation of the mounting plate 113, the toothed plate 122 screens the raw material particles. When there are particles that are too large, these particles will be separated from the raw material by the toothed plate 122. Finally, at a slightly higher position, as the toothed plate 122 flips, these particles slide into the collection box 123. Then, under the transmission action of the first belt drive 126 and the matching gear 125, the two sets of extrusion rollers 124 decompose the red lead into multiple strips. The drive rack 134 connected to the nozzle frame 115 swings with the nozzle frame 115, thereby driving the drive gear 132 to rotate back and forth. Then, the two sets of first racks 133 that mesh with the drive gear 132 drive the corresponding cutting plate 131 to complete the closing and opening action, and finally decompose the strip-shaped raw material into small particles that fall into the roller 112.

[0036] It should be noted that the first torsion spring 121 is used to achieve its own rotation when the toothed plate 122 passes over the output component 14.

[0037] Furthermore, such as Figures 1 to 5 As shown, the output component 14 includes a third motor 141 connected to the frame 100, an arc-shaped guide rail 142 connected to the frame 100, a slide rod 143 connected to the arc-shaped guide rail 142, a drive rod 144 connected to the output end of the third motor 141 and with one end sleeved outside the slide rod 143, a blocking ring 145 connected to the end of the slide rod 143 and located inside the roller 112, a first baffle 146 connected to the blocking ring 145, and a second baffle 148 connected to the first baffle 146 via a first telescopic member 147.

[0038] In this embodiment, by setting the output component 14 to be located at a slightly higher position during the rolling process of red lead particles, the powder adhering to the wall is dynamically scraped off by mechanical adhesion, causing the separated powder to fall back to the particle bed under the action of gravity, realizing the closed-loop reuse of raw materials and significantly improving the raw material utilization rate. In addition, when the particles need to be output, they are rotated to a slightly lower position, and the roller 112 rotates in a directional manner to form a forced unloading channel, realizing efficient and controllable output of particles and improving the operability of the device.

[0039] In detail, during the granulation process, the inner wall of the roller 112 is in contact with the bottom of the second baffle 148. The material adhering to the inner wall of the roller 112 is scooped up by the action of the second baffle 148. Since the second baffle 148 is located at the upper part of the annular path, the material falls and is placed exactly in the bottom granulation material. When the granulation work is completed, the third motor 141 drives the drive rod 144 to rotate. The drive rod 144 drives the slide rod 143 to move within the arc-shaped guide rail 142. Due to the limiting protrusion on the slide rod 143... This causes the slide bar 143 to rotate while the blocking ring 145 moves backward a certain distance. At this time, the first baffle 146 and the second baffle 148 connected to the blocking ring 145 move to the position below the drum 112. Due to the action of the first telescopic member 147, when the first baffle 146 moves outward with the blocking ring 145, the second baffle 148 still tightly abuts against one side of the mounting plate 113, thereby cooperating with the rotation of the drum 112 to realize the output of raw material particles. After the output is completed, it is reset under the drive of the third motor 141.

[0040] It should be noted that both the first baffle 146 and the second baffle 148 are inclined, which is conducive to scraping and guiding the output. The second baffle 148 has a protruding tip at the position where it contacts the roller 112, which is conducive to scooping up and separating the raw material. The protrusion on the slide bar 143 is connected to the arc-shaped guide rail 142. When resetting, the blocking ring 145 also returns to the roller 112. The material of the position where the second baffle 148 contacts the roller 112 and the protruding tip is a colloid with a certain degree of toughness, which ensures that the adhering powder is removed while preventing the roller 112 from being scratched.

[0041] Furthermore, such as Figure 1 and Figures 4 to 7 As shown, the screening mechanism 2 includes a first screening component 21 mounted on the mounting plate 113 for screening out qualified red lead and recovering iron balls, and a second screening component 22 mounted on the frame 100 for secondary screening of raw materials and recycling the raw materials into the fabric assembly 11.

[0042] In this embodiment, by setting up a screening mechanism 2, while screening qualified red lead particles, the iron balls are quickly recovered by magnetic attraction. After the shaping mechanism 3 has finished processing, the shaped particles are mixed with powder with poor water absorption and sent back to the drum 112 to continue growing, thereby improving the utilization rate of raw materials and production efficiency.

[0043] In detail, after the raw material particles are discharged from the output component 14, they enter the screening mechanism 2. First, the first screening component 21 retains the qualified red lead, and the remaining powder and smaller particles move to the second screening component 22. At the same time, the iron balls are recycled to the drum 112 by magnetic attraction in the first screening component 21. At the second screening component 22, the relatively larger particles are screened again for the shaping mechanism 3. The remaining powder and particles are combined with the shaped particles and then returned to the drum 112.

[0044] Furthermore, such as Figure 1 and Figures 4 to 7 As shown, the first screening assembly 21 includes a rotary screen frame 211 connected to the mounting plate 113, an electromagnetic module 212 connected to the side of the rotary screen frame 211, a first guide frame 213 connected to the frame 100 with its two ends located at the rotary screen frame 211 and the roller 112 respectively, and a flap 215 connected to the first guide frame 213 via a second torsion spring 214.

[0045] In this embodiment, by setting an electromagnetic module 212 and a flap 215 connected to a second torsion spring 214, the iron ball attracted by the magnet is pushed over the flap 215 as the roller screen frame 211 rises. Then, when the screen reverses, the flap 215 cannot swing downwards, thereby separating the iron ball from the roller screen frame 211 and sending it back into the roller 112.

[0046] In detail, the raw material particles rotate in the rotary screen cylinder along with the mounting plate 113. The rotary screen cylinder continuously screens the raw material particles to obtain qualified red lead particles. At the same time, the electromagnetic module 212 attracts the iron ball to the circumference. When the screening is completed, the first motor 111 drives the mounting plate 113 to rotate one revolution. At this time, the iron ball attracted to the side of the rotary screen cylinder is squeezed by the flip plate 215 and finally overcomes the magnetic force, and returns to the inside of the drum 112 along the first guide frame 213.

[0047] It should be noted that the flap 215 connected to the second torsion spring 214 can only rotate upwards. Therefore, during screening, the iron balls attracted by the electromagnetic module 212 will not fall, but will be squeezed over the flap 215. Alternatively, an inclined scraper can be set to scrape the iron balls off from above the flap 215, thus replacing the reverse operation of the mounting plate 113. A heating device can also be set inside the sieve cylinder to pre-dry the surface of qualified raw materials to prevent powder from adhering. These powders have poor adhesion and are prone to contamination after drying. At the same time, drying makes it easier for the remaining powder to be screened into the second screening component 22. Qualified red lead particles are finally scooped out and collected from the screen frame 227 by a robotic arm or collected by negative pressure suction.

[0048] Furthermore, such as Figure 1 and Figures 4 to 7As shown, the second screening assembly 22 includes an annular frame 221 connected to the frame 100, a transfer frame 222 connected to the annular frame 221, a second guide frame 223 connected to the frame 100 and communicating with the first guide frame 213, a fourth motor 224 connected to the frame 100, a drive wheel 225 connected to the output end of the fourth motor 224 and used to drive the annular frame 221, and a screen frame 227 connected to the frame 100 through a second telescopic member 226.

[0049] It is worth mentioning that, through the secondary screening of the screen frame 227, some slow-producing red lead particles of suitable size are screened out again, processed in conjunction with the shaping mechanism 3, and then combined with the remaining powder and sent back to the drum 112, thereby improving the utilization rate of raw materials and the efficiency of lead production.

[0050] In detail, some spherical particles that do not meet the qualified size and have originally smooth surfaces, along with red lead powder with poor water absorption, enter the second screening component 22. After screening by the screen frame 227, some slightly larger, smooth particles are collected and sent to the shaping mechanism 3, while the rest eventually fall into the ring frame 221. When all the shaped particles have fallen into the ring frame 221, the fourth motor 224 drives the ring frame 221 to reciprocate within a certain angle through the drive wheel 225. This causes the red lead powder with poor water absorption to aggregate on the surface of the shaped particles through the binder, changing the original smooth state and improving the adhesion effect of water mist. Finally, the fourth motor 224 drives the ring frame 221 to rotate, and together with the transfer frame 222, all the raw materials are sent into the second guide frame 223, and then flow through the first guide frame 213 and finally return to the drum 112.

[0051] It should be noted that the screen frame 227 has a screen structure in the front section of the limiting plate 321, and the rear section is used to set the shaping mechanism 3.

[0052] Furthermore, such as Figure 5 and Figures 7 to 8 As shown, the kneading assembly 31 includes a fifth motor 311 connected to the screen frame 227, a sprocket and chain drive 312 with its two ends connected to the screen frame 227 and the output end of the fifth motor 311 respectively, a fixed frame 313 connected to the screen frame 227 and connected to the sprocket and chain drive 312, and a kneading plate 314 connected to the fixed frame 313; The limiting component 32 includes a limiting plate 321 extending through the bottom of the screen frame 227, two sets of coaxial gear pairs 322 connected to the screen frame 227, two sets of second racks 324 connected to the limiting plate 321 via a cooperating rod 323 and respectively meshing with the two sets of coaxial gear pairs 322, and a third rack 325 connected to the fixed frame 313 and meshing with the coaxial gear pairs 322. The vibration assembly 33 includes a trigger plate 331 connected to the end of the screen frame 227 and multiple sets of levers 332 connected to the roller screen frame 211 and used to drive the trigger plate 331 to move.

[0053] In this embodiment, by setting the limiting component 32 and the vibration component 33, the screening efficiency of the screen frame 227 is improved, and the collected particles are evenly distributed to prevent accumulation. In conjunction with the kneading component 31, the particles are shaped and driven forward.

[0054] In detail, the smooth particles after screening are concentrated on one side of the limiting plate 321. As the rotary screen frame 211 rotates, multiple levers 332 connected to it sequentially press the trigger plate 331 at the end of the screen frame 227. As the levers 332 move circumferentially, they push the screen frame 227 to move a certain distance and then separate from the trigger plate 331. At this time, the screen frame 227 shakes left and right when the second telescopic member 226 drives it to reset, thereby promoting the uniform distribution of the screened particles. After collection is completed, the fifth motor 311 starts and drives the fixed frame 313 to move through the sprocket and chain transmission member 312. The fixed frame 313 drives the kneading plate 314 to press downward and move forward, and the particles... The particles also roll forward, forming a capsule shape. In addition, when the kneading plate 314 moves towards the particles, the third rack 325 connected to the fixed plate drives the coaxial gear pair 322 at the upper position to rotate, which in turn drives the corresponding third rack 325 to move downward. In conjunction with the cooperating rod 323, the limiting plate 321 is moved downward, thereby achieving avoidance. Correspondingly, when the kneading plate 314 drives the particles to move, after passing the limiting plate 321, the third rack 325 connected to the fixed plate drives the coaxial gear pair 322 at the lower position to rotate, thereby restoring the limiting plate 321 to its limiting state, which is used to prevent the particles from entering the shaping component 34 by themselves due to the vibration component 33.

[0055] It should be noted that the bottom of the kneading board 314 is made of flexible material, which is used to balance the size difference between the particles through slight deformation. The kneading board 314 always remains horizontal during movement.

[0056] Example 2 like Figures 7 to 10 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: like Figures 7 to 10As shown, the shaping component 34 includes multiple shaping frames 341 passing through the screen frame 227, a support plate 343 connected to the multiple shaping frames 341 and with multiple right-angle frames 342 connected to the top, multiple sets of hole cones 345 passing through the shaping frames 341 and connected to the shaping frames 341 by springs 344, a drive shaft 346 passing through the screen frame 227, a second belt drive component 347 with both ends connected to the drive shaft 346 and the output end of the fifth motor 311 respectively, a disc-shaped cam 348 connected to the drive shaft 346 and used to drive the support plate 343 to move up and down, and multiple sets of glue injection frames 349 connected to the screen frame 227 and corresponding to the shaping frames 341.

[0057] In this embodiment, by setting the shaping component 34 in conjunction with the kneading component 31 to form a groove on the outer wall of the capsule-shaped particles, and using the hole cone 345 to form a hole on the inner wall of the groove, the adhesion of the binder is increased. In the subsequent mixing, the powder is ensured to gather at the groove position, thereby forming an uneven surface and enhancing the adhesion of water mist.

[0058] In detail, when the fifth motor 311 rotates and drives the kneading component 31 to work, the fifth motor 311 also drives the transmission shaft 346 to rotate through the second belt transmission component 347. The transmission shaft 346 then drives the lifting plate 343 to move up and down through the disc cam 348. During the process, the lifting plate 343 squeezes multiple cone holes 345 out through the right angle frame 342. When resetting, the cone holes 345 also retract under the action of the spring 344. Thus, when the kneading plate 314 carries the particles through the shaping frame 341, multiple grooves will be formed on the surface of the particles, and holes will be generated in the grooves. Subsequently, when the particles pass through the glue injection frame 349, the glue injection frame 349 fits with the edge of the groove. The glue that is arched at the top outlet of the glue injection frame 349 adheres to the inside of the groove as the particles roll.

[0059] It should be noted that the amount of binder should be small to avoid affecting the performance of red lead. Therefore, the added binder should be confined within the groove of the particle, and the entire particle should not be covered. This is to maximize the surface area and ensure that the particles have an irregular shape, which is the best for moisture retention. In addition, if the binder is applied to the entire particle, the powder with poor water absorption will form a new protective shell on the outside of the particle, which is not only not conducive to granulation, but also leads to obvious delamination and affects the overall strength. When the powder is squeezed and collided with the binder in the groove, more binder is gradually squeezed out from the inside of the groove, thus gradually forming a certain height. The dispensing frame 349 uses a pressure sensor to identify the number of particles passing through and then replenishes the binder accordingly. The right angle frame 342 and the multiple cones 345 are squeezed at a 90° angle, which minimizes the resistance when pushing the cones 345. The angle can also be changed as needed.

[0060] Work steps Step 1, Rolling: At the start of the rolling process, the fabric assembly 11 combines water mist and red lead powder by alternating mixing. After the raw material falls, it forms a preliminary aggregate under the collision of the iron ball. Then, it grows continuously in the rolling process, increasing its volume. During the rolling process, the separation assembly 12 sweeps over the raw material, collects some particles that grow too fast, and squeezes them into strips to cooperate with the cutting assembly 13 to reform small particles. Step 2, Output: After the rolling process is completed, the particles are quickly output through the output component 14 and enter the screening mechanism 2. First, the first screening component 21 retains the qualified red lead, and the remaining powder with poor water absorption and small and smooth particles move to the second screening component 22. At the same time, the iron balls in the first screening component 21 are recycled by magnetic attraction to move towards the roller 112. At the second screening component 22, the relatively large particles are screened again and sent to the shaping component 34. The remaining powder and particles wait to be combined with the shaped particles. Step 3: Shaping. The smooth particles after screening are evenly distributed under the action of the limiting component 32 and the vibration component 33 and are waiting for processing. After screening, the kneading component 31 drives the particles forward and the particles roll to form a capsule shape. Then, the shaping component 34 is used to form a groove with holes on the outer wall of the particles and the adhesive is added to the groove. Step 4: Reuse. The processed particles fall into the remaining poorly absorbent powder and are mixed together with the swing of the second screening component 22. This causes the poorly absorbent powder to form protrusions with the binder in the groove position, increasing the adhesion ability. Finally, under the action of the second screening component 22, it returns to the granulation mechanism 1.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
