Detailed Embodiment

[0021] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] As Figures 1 to 4As shown in the figure, a plastic masterbatch screening machine that is convenient for cleaning includes a housing 1 and a spraying assembly 6. High-strength springs 3 are provided at the four corners of the lower end of the housing 1. The housing 1 provides overall structural support and fixation to ensure the stability and structural strength of the entire device. The high-strength springs 3 are shaken through the high-speed vibration of the vibration motors 4, and the feet 2 are connected to the housing 1. The feet 2 are provided at the lower ends of the four groups of high-strength springs 3. A vibration motor 4 is provided at the center of the lower end face of the housing 1. There are two sets of vibration motors 4. The vibration motors 4 generate vibration force to make the material to be screened produce periodic jumping movements on the sieve holes, so as to achieve the purpose of screening. The two ends of the high-strength springs 3 are respectively connected to the housing 1 and the feet 2. The inclination angles of the two sets of vibration motors 4 are both 45 degrees, and the positions of the two sets of vibration motors 4 correspond symmetrically, which can provide uniform vibration force, ensure effective screening of the material, and improve the screening efficiency. An inlet 5 is provided at the upper end of the right side of the housing 1. The inlet 5 is used to input the raw material to be screened;

[0023] A primary sieve plate 7 is provided in the inner cavity of the housing 1. The mesh surface of the primary sieve plate 7 is honeycomb-shaped. The primary sieve plate 7 can effectively filter out larger particles without getting stuck. A secondary sieve plate 8 is provided below the primary sieve plate 7. The mesh surface of the secondary sieve plate 8 is in the shape of several diamond meshes. The secondary sieve plate 8 can screen medium-sized particles. A tertiary sieve plate 9 is provided below the secondary sieve plate 8. The mesh surface of the tertiary sieve plate 9 is in the shape of several small round holes. The tertiary sieve plate 9 can filter small particles, which can improve the screening efficiency. The inclination angles of the primary sieve plate 7, the secondary sieve plate 8 and the tertiary sieve plate 9 are all 20 degrees. An outlet 10 is provided on the left side of the housing 1. The inclination of the primary sieve plate 7, the secondary sieve plate 8 and the tertiary sieve plate 9 at 20 degrees can accurately vibrate and slide the masterbatch to the outlet 10 during screening;

[0024] The spraying assembly 6 is arranged on the upper end face of the outer casing 1. The spraying assembly 6 includes a water storage tank 601, a water pump 602, a water delivery pipe 603 and a multi-directional nozzle 604. The water storage tank 601 is arranged on the right side of the upper end face of the outer casing 1. The water storage tank 601 is used to store the cleaning water required for spraying to ensure that cleaning can be continuously carried out for a long time. A water pump 602 is arranged on the left side of the water storage tank 601. The input end of the water pump 602 is connected to the water storage tank 601. The upper end of the water delivery pipe 603 is connected to the output end of the water pump 602 through the outer casing 1. The water pump 602 pumps water from the water storage tank 601 and transports it to the multi-directional nozzle 604 through the water delivery pipe 603 to provide the water pressure required for spraying. The output end of the water pump 602 is provided with the water delivery pipe 603. The outer surface of the water delivery pipe 603 is provided with the multi-directional nozzle 604. There are three groups of multi-directional nozzles 604. The multi-directional nozzle 604 can achieve all-round spraying to ensure that the sieve mesh is thoroughly cleaned. A sewage outlet 11 is arranged below the three discharge ports 10, which is used to discharge the cleaned water and the waste generated by the screening process, keep the equipment clean, and facilitate the treatment of waste. An air delivery pipe 13 is arranged at the lower end of the right side of the outer casing 1. A fan 12 is arranged on the right side of the air delivery pipe 13. The output end of the fan 12 is connected to the air delivery pipe 13. The fan 12 provides air flow, and the air flow is sent into the inner cavity at the bottom of the outer casing 1 through the air delivery pipe 13, so as to help clean the dust at the bottom end and air-dry the moisture, improving the cleaning efficiency. The inclination angle of the bottom end face of the inner cavity of the outer casing 1 is 20 degrees. The 20-degree inclination of the bottom end face of the outer casing 1 facilitates the discharge of dust and water from the inner cavity.

[0025] In summary, as Figures 1 to 4 shown, for this plastic masterbatch screening machine that is convenient to clean, the vibration motor 4 generates a vibration force, and the generated vibration is transmitted to the high-strength spring 3 at the upper end of the support feet 2. While vibrating, it drives the outer casing 1 to vibrate, so that the material to be screened generates a periodic jumping motion on the sieve plate, thereby achieving the purpose of screening. When the material enters the inner cavity of the outer casing 1 from the feed port 5, it first passes through the honeycomb-shaped mesh surface of the primary sieve plate 7, and the larger particles are filtered out, and the smaller particles pass through. The remaining particles pass through the diamond-shaped grid structure of the secondary sieve plate 8 for further separation of particles. Finally, the particles pass through the small round holes of the tertiary sieve plate 9 for the final screening to obtain the smallest particles. Each sieve plate can accurately vibrate and slide different masterbatches to the discharge port 10 during screening by inclining 20 degrees, and the whole process realizes multi-stage classification screening;

[0026] When screening, the blower 12 is started, and air flow is provided by the blower 12. The air flow is sent into the inner cavity at the bottom of the outer casing 1 through the air supply pipe 13, so as to help clean the dust at the bottom end. When it is necessary to clean the inner cavity of the outer casing 1, the water pump 602 in the spraying assembly 6 is started. The water pump 602 pumps out the water in the water storage tank 601. The pumped water is sent into the multi-directional nozzle 604 after passing through the water supply pipe 603, and then flows through the first-stage sieve plate 7, the second-stage sieve plate 8 and the third-stage sieve plate 9 in sequence for flushing operation. Subsequently, the sewage is discharged through the sewage outlet 11. After the cleaning is completed, the blower 12 is started again to perform air-drying operation on the bottom.
