Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a plastic particle screening device. Background Art

[0002] Screening devices are devices used to screen materials or separate particles, usually composed of screens or screen plates. They are widely used in industrial production and processing to separate solid particles or powders of different sizes or shapes, as well as liquids from solids. The design of the screening device can vary according to the requirements of the specific application, including the size of the screening device, the size of the screen hole, the screen plate or screen material, etc. Common screening devices include vibrating screens, rotary screens, screening machines, sifters, etc. They are widely used in mining, building materials, chemicals, food processing and other fields.

[0003] When applying for the present invention, the applicant found through search that a Chinese patent disclosed a "plastic particle screening device", and its application number is "CN202222154124.8". This patent mainly uses a vibration screening machine body, and the vibration screening machine body is provided with a screen, and the screen and the vibration screening machine body are slidably connected. The vibration screening machine body is connected to a limited position structure, and a pair of racks are fixedly connected to the inner wall of the vibration screening machine body, and support columns are fixedly connected to both ends of the control rod. The pressure strip is used to contact the screen, and a first spring is in contact between the pair of the contact rods, and a control is slidably connected to the control rod.

[0004] However, screening devices without conveyor belts need to rely on operators to manually feed raw materials into the screen. This manual operation method will greatly reduce production efficiency because operators need to spend more time and energy to handle raw materials. At the same time, this also increases labor costs because more workers are needed to maintain the normal production process. Due to the lack of an automated conveying system, operators need to frequently move around the screening device and come into contact with the vibrating screen, which may increase the unsafety of the working environment and pose a risk of accidental injury. In addition, using only one mesh size screen will limit the screening effect on the material, and the material cannot be well classified and graded, affecting the screening efficiency and product quality. If materials of different particle sizes need to be screened, additional screening steps or equipment may be required, increasing the process complexity and cost. If the material contains impurities or materials of different particle sizes, a single mesh size screen cannot effectively separate them, which may cause mixed contamination of the product and affect product quality.

[0005] To this end, we propose a plastic particle screening device. Utility Model Content

A rotating shaft 16 is movably connected to the inside of the conveyor belt shell 15, and a roller is movably connected to the outer surface of the rotating shaft 16. A conveyor belt 11 is movably connected to the outer surface of the roller. A guide bar 12 is arranged on the outer surface of the conveyor belt 11. The screening device shell 10 is made of durable metal material, such as stainless steel, to ensure that it can withstand the vibration and pressure during the screening operation.

[0026] A fixing part 13 is fixedly connected to the outer surface of one side of the conveyor belt shell 15, and a motor 14 is fixedly connected to the outer surface of the fixing part 13. The output end of the motor 14 is fixedly connected to the rotating shaft 16.

[0027] Four spring seats are fixedly connected to the top of the first base frame 1, and the spring seats correspond to the spring seats at the bottom of the screening device housing 10. The first base frame 1 and the spring seats connected thereto are made of a material with good elasticity and durability, such as steel or alloy material, to ensure the stability and reliability of the screening device.

The larger aperture of the first screen 9 can effectively screen out larger particles of material and separate them. Smaller particles of material pass through the first screen and continue to be transmitted downward. Smaller particles of material pass through the second screen 6 for more detailed screening. The smaller aperture of the second screen 6 The aperture helps to remove smaller impurities and improve the screening effect.
