[0031] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0032] In this embodiment, an online packaging device for recycled rubber particles relates to the field of rubber recycling technology. A vertically arranged conveying auger is used, and holes are opened on the blades of the conveying auger so that rubber dust can be deposited downward and separated from the rubber particles. At the same time, a suction unit 220 is arranged in the hopper 210 to suck the dust in the rubber particles, completely remove the dust in the rubber particles, and avoid pollution caused by dust and waste of materials.

[0033] See also Figures 1 to 6 In this embodiment, an online packaging device for recycled rubber particles includes: a vertical lifting component 100, a suction separation component 200 and a packaging bag component 300. The vertical lifting component 100 includes a vertically arranged first conveying auger 110. The first conveying auger 110 includes a spiral blade 111. The spiral blade 111 can convey rubber particles from bottom to top. A hole 112 is provided on the spiral blade 111. Rubber dust mixed in the rubber particles can leak from the hole 112, so that the rubber dust is separated from the rubber particles and gathered at the bottom of the first conveying auger 110, so as to prevent the scattered rubber dust from polluting the atmosphere.

[0034] The suction separation component 200 includes a hopper 210 connected to the output end of the first conveying auger 110 and a suction unit 220. The suction unit 220 is arranged in the hopper 210. The rubber particles output from the first conveying auger 110 are scattered in the hopper 210. The suction unit 220 can suck the rubber dust scattered from the rubber particles, effectively separate the rubber dust from the particles, and prevent the dust from diffusing into the air.

[0035] The bagging assembly 300 includes a material distribution unit 310 , which is connected to the output end of the hopper 210 . The output end of the material distribution unit 310 can quantitatively output rubber particles to ensure that the packaging amount of each bag is the same.

[0036] In some embodiments, see Figure 1 and Figure 2The vertical lifting assembly 100 also includes a discharge unit 120, which includes a material accumulation chamber 121 and a discharge pipe 122 arranged at the bottom of the first conveying auger 110. The dust passing through the holes 112 of the spiral blades 111 gathers in the material accumulation chamber 121 under the action of gravity to store the rubber dust. The two ends of the discharge pipe 122 are respectively connected to the material accumulation chamber 121 and the outside world. The rubber dust stored in the material accumulation chamber 121 can be discharged with the help of the discharge pipe 122 and stored in a container. The dust is effectively collected and processed, reducing the dust content in the operating environment.

[0037] In some embodiments, see Figure 1 and Figure 3 The suction unit 220 includes a suction cylinder 221, the outer wall of which is arranged relative to the inner wall of the hopper 210 to form an annular gap for the rubber particles to pass through. When the rubber particles enter the hopper 210 through the annular gap, the lighter rubber dust is easily adsorbed to the outer wall of the suction cylinder 221 due to the aerodynamic effect.

[0038] The outer wall of the suction cylinder 221 is provided with a vent 222 for sucking rubber dust, and the vent 222 can effectively capture and suck the dust, thereby separating it from the heavier rubber particles. The rubber dust is sucked in a relatively closed space to prevent it from spreading to the outside environment, which not only improves the air quality of the working environment, but also protects the health of the workers.

[0039] In some embodiments, see Figures 3 to 6 The suction cylinder 221 includes a conical portion 221a, a base portion 221b and a cylindrical portion 221c arranged relative to the output end of the first conveying auger 110. The conical portion 221a is arranged to expand gradually, so as to disperse and diffuse the rubber particles from the first conveying auger 110 to the surroundings, thereby promoting the separation between the rubber particles and between the rubber particles and the rubber dust. The two ends of the cylindrical portion 221c are respectively connected to the conical portion 221a and the base portion 221b. The conical portion 221a, the base portion 221b and the cylindrical portion 221c cooperate to form a hollow suction chamber, and a negative pressure is formed in the suction chamber, so that the external air can be sucked. A plurality of vents 222 are provided on the cylindrical portion 221c and the base portion 221b, and the vents 222 connect the suction chamber and the inner cavity of the hopper 210, and can suck the rubber dust dispersed between the suction cylinder 221 and the hopper 210 into the suction chamber, thereby achieving separation between rubber particles and rubber dust.

[0040] It should be noted that the diameter of the vent hole 222 is smaller than the minimum diameter of the rubber particles, so that the rubber dust can enter the suction chamber through the vent hole 222, but the rubber particles cannot pass through the vent hole 222, thereby achieving complete separation of the rubber dust and particles.

[0041] In some embodiments, see Figures 3 to 5 A plurality of vibrators 223 are provided on the cylindrical portion 221c. The plurality of vibrators 223 are fixedly connected to the outer wall of the cylindrical portion 221c and are arranged around the central axis of the cylindrical portion 221c. The vibrators 223 are located in the annular gap. The plurality of vibrators 223 maintain the rubber particles in the cylindrical portion 221c and the annular gap in an active state through vibration, thereby reducing friction and accumulation between the particles and enabling the particles to pass through the annular gap more smoothly.

[0042] The presence of the vibrator 223 increases the kinetic energy difference between the rubber particles and the dust, making it easier for the lighter dust to be shaken off and enter the suction system through the vent 222. The vibrator 223 can improve the separation effect of the dust and particles, ensuring that more dust is effectively captured and sucked.

[0043] In some embodiments, see Figure 3 The conical portion 221a is provided with a protrusion 221d, and a plurality of protrusions 221d are arranged around the conical portion 221a. The plurality of protrusions 221d on the conical portion 221a disperse the rubber particles when passing through the conical portion 221a. Through this dispersion effect, the contact area between the particles and the dust increases, and the dust is more easily separated from the surface of the particles, thereby improving the efficiency of dust separation. At the same time, the design of the protrusion 221d causes the particles to generate disturbances and friction on the surface of the conical portion 221a, further promoting the dissipation of dust from the surface of the particles.

[0044] In some embodiments, see Figure 3 and Figure 4 The suction unit 220 also includes a connecting ring 224, which is sleeved on the suction cylinder 221. The two ends of the connecting ring 224 are fixedly connected to the inner wall of the hopper 210 and the suction cylinder 221 respectively. The connecting ring 224 fixes the suction cylinder 221 to the inner wall of the hopper 210 to form a stable structure, which prevents the suction cylinder 221 from shaking during operation, thereby maintaining the stability of the system. The connecting ring 224 is provided with a plurality of openings 224a for the rubber particles to pass through. The openings 224a on the connecting ring 224 provide a path for the rubber particles to pass through, ensuring that the particles smoothly enter the annular gap. The existence of the openings 224a allows the rubber particles to be effectively diverted and guided, reducing the possibility of particle accumulation.

[0045] In some embodiments, see Figure 6The suction unit 220 further includes a suction pipe 225, one end of which is gradually expanded to form a bell mouth, and the bell mouth is vertically arranged in the suction cylinder 221. The arrangement of the bell mouth can effectively increase the coverage of the suction area. The shape of the bell mouth helps to capture and concentrate rubber dust in the air over a larger area, thereby improving the efficiency of dust capture. The gradually expanding design of the bell mouth can effectively reduce the resistance of air flow, making it easier for air containing rubber dust to be sucked into the suction pipe 225, thereby improving the suction efficiency and effect.

[0046] A filter cartridge and a vacuum pump are provided at one end of the suction pipe 225 away from the bell mouth. The vacuum pump can provide negative pressure suction force, and the rubber dust can be enriched in the filter cartridge.

[0047] The suction pipe 225 centrally sucks the dust through the bell mouth, so that the dust is captured and sucked out before entering the annular gap, which can reduce the suspension and diffusion of dust in the air and keep the working area clean, thereby reducing the risk of dust inhalation by operators and protecting operators from harm caused by rubber dust.

[0048] In some embodiments, see Figure 1 The material distribution unit 310 includes a second conveying auger 311 that can rotate intermittently. The second conveying auger 311 rotates intermittently for a certain number of times to output a certain amount of rubber particles to the output end of the second conveying auger 311. The output end of the second conveying auger 311 is arranged relative to the packing bag to achieve accurate measurement of the conveying amount each time, ensuring that the amount of rubber particles in each packing bag is consistent, thereby achieving quantitative packaging.

[0049] As an alternative embodiment, the material distribution unit 310 includes a rotatable belt conveyor, one end of which is arranged relative to the output end of the hopper 210. The belt conveyor can realize continuous and quantitative transportation, is suitable for particles of different sizes and shapes, and is easy to link with other equipment.

[0050] Workflow: First, start the first conveying auger 110 and the second conveying auger 311, and turn on the vacuum pump. Then, input the rubber particles from the input end of the first conveying auger 110, and the rubber particles rise vertically along the first conveying auger 110, and the rubber dust gathers at the bottom of the first conveying auger 110 through the hole 112 of the spiral blade 111. The rubber particles output from the top of the first conveying auger 110 are input into the hopper 210 through the pipeline, and the rubber particles fall into the conical part 221a and are dispersed. The rubber dust is sucked into the suction chamber and separated from the rubber particles. The dust in the rubber particles is completely removed to avoid pollution caused by dust and waste of materials.

[0051] The above description is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered by the present invention.
