[0035] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0036] According to some embodiments of this utility model, refer to Figures 1 to 4 The crushed material distribution device includes a tank 100, a stirring component 200, a fixing rod 300, and a feeding assembly 400. The upper end of the tank 100 has a feeding port 110, and the bottom of the tank 100 has a discharge port 120. The stirring component 200 includes a stirring assembly 220 and a stirring motor 210. The stirring assembly 220 is located inside the tank 100 and includes a rotating shaft 221, a stirring rod 222, and a sweeping rod 223. The rotating shaft 221 is rotatably connected to the tank 100, and the stirring rod 222 and the sweeping rod 223 are both fixedly connected to the rotating shaft 221. The sweeping rod 223 is located below the stirring rod 222. The stirring motor 210 drives the rotating shaft 221 to rotate around its own axis, and the sweeping rod 223 pushes the material into the discharge port 120. A fixing rod 300 is inserted through the tank body 100. Multiple fixing rods 300 are distributed around the circumference of the tank body 100. One end of the fixing rod 300 located on the outside of the tank body 100 is connected to an electrostatic rope 310, which is grounded. The feed inlet 410 of the feeding assembly 400 is connected to the discharge outlet 120. The feeding assembly 400 is used to transport materials.

[0037] Material is fed into tank 100 through feeding port 110. Stirring motor 210 drives rotating shaft 221 to rotate. Rotating shaft 221 drives sweeping rod 223 and stirring rod 222 to rotate. Stirring rod 222 stirs the material, causing relative movement between the material and fixed rod 300. When the material comes into contact with fixed rod 300, the static electricity on the material is transferred to fixed rod 300. The static electricity on fixed rod 300 is transferred to the ground by static rope 310, thereby removing static electricity from the material, enhancing the fluidity of the material, and ensuring that the material can smoothly pass through feeding port 120 into feeding assembly 400. Feeding assembly 400 then transfers the material to the next process.

[0038] Furthermore, the feeding port 110 is equipped with an ion generator 130, which is used to remove static electricity from the material. Understandably, the ion generator 130 can eliminate the static electricity accumulation of the material before it enters the tank 100. This ion generator 130 system consists of two parts: an external power supply unit boosts the input 24V DC power into the required high-voltage DC power; this high-voltage power is transmitted via a dedicated high-voltage cable to the ion generator 130 body located at the feeding port 110. The ion generator 130 has specially designed electrodes installed inside, which continuously generate a large number of positive and negative ions around its annular region using the received high-voltage power, forming a dense ionized air region. When the material falls into the tank 100 through the feeding port 110, it first passes through this strongly ionized region. The static charge (whether positive or negative) carried on the surface of the material is effectively attracted and combined by ions of opposite polarity in the ion cloud, thereby achieving static neutralization. The static-removed material then enters the tank 100. The stirring rod 222 inside the tank 100 stirs the material, causing relative movement between the material and the fixed rod 300. When the material comes into contact with the fixed rod 300, it can further transfer static electricity from the material to the fixed rod 300. The static electricity on the fixed rod 300 is then transferred to the ground by the static rope 310, thereby removing static electricity from the material. The fixed rod 300 will conduct away any trace amounts of static electricity that may be generated again during the stirring process due to friction, ensuring a safe and stable operating environment inside the tank. The combined effect of the ion generator 130 and the fixed rod 300 can eliminate static electricity and break up lumpy materials.

[0039] Understandably, during the film crushing process, the material experiences intense friction, collision, and separation with the crusher blades, chamber walls, and within itself. Plastic is an excellent insulator, making it difficult for the static charge generated by friction to dissipate through conduction, leading to charge accumulation on the surface of the crushed particles. The particles acquire the same charge, and Coulomb repulsion occurs between these particles. This repulsion prevents the particles from clustering together, making the pile "loose," increasing its volume, and reducing its flowability. Therefore, by introducing statically charged material into the tank 100, the static electricity can be transferred to the fixed rod 300 during stirring, thereby removing the static electricity from the material.

[0040] According to some embodiments of this utility model, refer to Figures 2 to 4 The fixing rod 300 is horizontally positioned and extends radially along the tank body 100, meaning the axial direction of the fixing rod 300 coincides with the radial direction of the tank body 100. Multiple first support rods 320 are connected to the fixing rod 300. The lower ends of the first support rods 320 are fixedly connected to the fixing rod 300. The multiple first support rods 320 are spaced apart along the axial direction of the fixing rod 300. The arrangement of multiple first support rods 320 increases the contact area between the first support rods 320 and the material, thereby allowing the static electricity of the material to be transferred to the fixing rod 300 through the first support rods 320.

[0041] Preferred, refer to Figures 2 to 4 The stirring rod 222 is connected to multiple second support rods 230. The upper ends of the second support rods 230 are fixedly connected to the stirring rod 222. The multiple second support rods 230 are spaced apart along the axial direction of the stirring rod 222. When the stirring rod 222 rotates, at least one second support rod 230 passes between two adjacent first support rods 320. When the stirring rod 222 rotates to... Figure 2 As shown, multiple first support rods 320 and multiple second support rods 230 are staggered. The second support rods 230 push the material to move, thereby increasing the contact area between the material and the first support rods 320.

[0042] Understandably, the cooperation of the first support rod 320 and the second support rod 230 forces the material to shuttle through, forcibly "push," "push away," or "lift" the material located in the area between the first support rods 320, forcing the material to shift and be pushed towards the nearby fixed rod 300 and its first support rod 320, significantly increasing the chances of collision and contact between the material and the first support rod 320. The staggered arrangement of the stationary first support rod 320 and the moving second support rod 230 allows the material to be repeatedly agitated, squeezed, and penetrated in this relatively moving "gap," greatly increasing the frequency of effective contact between the material particles and the first support rod 320.

[0043] According to some embodiments of this utility model, a fixed rod 300 is connected to a plurality of third support rods 330. The upper ends of the third support rods 330 are fixedly connected to the fixed rod 300. The plurality of third support rods 330 are spaced apart along the axial direction of the fixed rod 300, and the plurality of first support rods 320 and the plurality of third support rods 330 are staggered along the axial direction of the fixed rod 300. The arrangement of the plurality of third support rods 330 can increase the contact area between the third support rods 330 and the material, thereby allowing the static electricity of the material to be transferred to the fixed rod 300 through the third support rods 330.

[0044] Understandably, multiple third support rods 330 can increase spatial coverage density and contact dimensions. By adding third support rods 330 connected above the fixed rod 300 on top of the first support rod 320, support rods are distributed on both the upper and lower sides of the fixed rod 300, greatly increasing the density and coverage of the fixed rod 300 system in three-dimensional space. This also avoids excessive density of support rods at the same point, which could obstruct material flow or create dead zones. Simultaneously, it ensures that support rods extend from all angles along the entire length of the fixed rod 300, maximizing space utilization and contact probability.

[0045] According to some embodiments of this utility model, refer to Figures 2 to 4 One end of the sweeping rod 223 is connected to the outer peripheral wall of the rotating shaft 221, and multiple sweeping rods 223 are distributed circumferentially along the rotating shaft 221. In this embodiment, there are three sweeping rods 223, which extend radially along the tank body 100. One end of the tank body 100 near the middle of the tank body 100 is fixedly connected to the rotating shaft 221. The sweeping rod 223 has a certain distance from the bottom of the tank body 100 to avoid static electricity generated by friction. During rotation, the sweeping rod 223 sweeps the material into the discharge port 120.

[0046] Understandably, if the sweeping bar 223 were to be in close contact with or rub against the bottom of the tank, the intense metal-to-metal friction during high-speed rotation would generate new static electricity. The sweeping bar 223 maintains a certain gap with the bottom of the tank body 100, for example, a few millimeters to tens of millimeters, depending on the particle size of the material. This allows the sweeping bar 223 to push the material without directly rubbing against the bottom of the tank, thus avoiding the generation of new static electricity during cleaning. At the same time, this gap also allows fine materials to pass through, preventing the sweeping bar 223 from getting stuck or excessively worn. This ensures that the sweeping bar 223 can effectively scrape the accumulated material layer without contacting the bottom of the tank.

[0047] Preferred, refer to Figure 3 The sweeping bar 223 includes a first inclined plate 241 and a second inclined plate 242, with the upper side of the first inclined plate 241 connected to the upper side of the second inclined plate 242. During rotation, the upper sides of the first inclined plate 241 and the second inclined plate 242 can guide the movement of materials.

[0048] Understandably, the first inclined plate 241 and the second inclined plate 242 are connected in an inverted V shape, with their upper surfaces forming a guiding slope. One of their upper surfaces is the receiving surface, and the other is the guiding surface. When the sweeping bar 223 rotates and propels the material, the receiving surface first contacts the material pile, using the inclined angle to slightly "lift" or "separate" the material upwards, reducing initial pushing resistance and preventing material compaction due to hard compression. During the continuous movement of the sweeping bar 223, the guiding surface provides a smooth "slide" for the pushed material, guiding it to flow downwards and reducing material accumulation and backflow on the surface of the sweeping bar 223.

[0049] According to some embodiments of this utility model, refer to Figure 1 and Figure 2 The feeding assembly 400 includes a barrel 420, a feeding screw 430, and a drive unit 440. The feeding screw 430 is located inside the barrel 420 and is rotatably connected to the barrel 420. The drive unit 440 drives the feeding screw 430 to rotate along its own axis. The feed inlet 410 of the barrel 420 is connected to the discharge outlet 120. The drive unit 440 is a drive motor, which can drive the feeding screw 430 to rotate, thereby causing the material to move along the axial direction of the feeding screw 430.

[0050] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 The crushed material distribution device also includes a first sleeve 340, with multiple first sleeves 340 corresponding one-to-one with multiple fixed rods 300. The first sleeve 340 is fitted onto the fixed rod 300, and the first sleeve 340 and the fixed rod 300 are fixedly connected by bolts. Multiple first support rods 320 are connected to the first sleeve 340, and the lower end of the first support rod 320 is fixedly connected to the first sleeve 340. The mixing assembly 220 also includes a second sleeve 250, which is fitted onto the mixing rod 222, and the second sleeve 250 and the mixing rod 222 are fixedly connected by bolts. (Refer to...) Figure 2 and Figure 3 The second sleeve 250 is connected to multiple second support rods 230, with the upper end of each second support rod 230 fixedly connected to the second sleeve 250. It is understood that the number of first support rods 320 and second support rods 230 can be adjusted by replacing different first sleeves 340 and second sleeves 250, thus adapting to various environmental requirements. When a first support rod 320 or a second support rod 230 is damaged due to long-term material impact and wear, the entire first sleeve 340 assembly can be disassembled for replacement or repair simply by loosening the bolts, without needing to replace or disassemble the fixing rod 300, simplifying maintenance and reducing downtime and costs.
