[0002] Masterbatch is an aggregate made by uniformly loading an extraordinary amount of pigment into a resin. Masterbatch is generally composed of three parts: colorant, carrier and dispersant. It is mixed in a high-speed mixer, crushed and extruded into particles. Masterbatch has significant advantages in the plastic processing process, such as high concentration, good dispersion and cleanliness.

[0003] Masterbatch is a new type of polymer colorant, also known as pigment preparation. When masterbatch is put into product production, particles with larger length and particle size need to be removed. Generally, it is screened before feeding.

Therefore, it is necessary to provide a plastic masterbatch feeding device with a screening structure, which adds screening results at the silo position of the spiral feeding equipment, thereby realizing the integrated operation of screening and feeding, reducing the processing steps and improving the processing efficiency.

[0021] Hereinafter, an embodiment of a plastic masterbatch feeding device with a screening structure of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-4 The utility model shows a plastic masterbatch feeding device with a screening structure according to an embodiment of the present invention, comprising a conveying pipe 1, a driving motor 6 is fixedly installed on the left side of the conveying pipe 1, a spiral conveying rod 7 is rotatably connected to the inner cavity of the conveying pipe 1 through a bearing, the left end of the spiral conveying rod 7 penetrates to the outside of the conveying pipe 1 and is fixedly connected to the output shaft of the driving motor 6, a feeding pipe 11 is connected to the right side of the bottom of the conveying pipe 1, a silo 2 is arranged on the top of the conveying pipe 1, the bottom of the silo 2 is connected to the feeding port of the conveying pipe 1, a vibration box 3 is arranged on the top of the silo 2, support seats 54 are welded on both sides of the front and back surfaces of the vibration box 3, triangular support plates 55 are welded on both sides of the top of the front and back surfaces of the silo 2, support springs 56 are welded on both sides of the top of the triangular support plate 55, and the top of the support spring 56 is welded to the bottom of the support seat 54. Through the coordinated use of the support seat 54, the triangular support plate 55 and the support spring 56, the vibration box 3 is elastically supported, so that the eccentric rotating block 52 During the swinging process, when the vibration is transmitted to the vibration box 3, the vibration box 3 can generate a strong vibration frequency. A discharge trough 8 is opened on the right side of the inner cavity of the vibration box 3, and a collection plate 9 is fixedly connected to the right side of the vibration box 3. A discharge pipe 10 is connected to the front side of the collection plate 9. Through the coordinated use of the discharge trough 8, the collection plate 9 and the discharge pipe 10, the masterbatch that has not passed through the surface of the sieve plate 4 can be collected and discharged in a centralized manner, which is convenient for users to store them. The inner cavity of the vibration box 3 is fixedly connected with the sieve plate 4, and the sieve plate 4 is inclined. The right side of the top of the sieve plate 4 is flush with the bottom of the inner cavity of the discharge trough 8. The inner cavity of the vibration box 3 is provided with a vibration component 5, and the vibration component 5 includes a rotating rod 51 rotatably connected to the inner cavity of the vibration box 3.

[0023] Working principle: When the utility model is used, the user turns on the servo motor 53, and the servo motor 53 drives the rotating rod 51 to rotate in the inner cavity of the vibration box 3, and the rotating rod 51 drives the eccentric rotating block 52 to rotate eccentrically. Under the elastic support of the support seat 54, the triangular support plate 55 and the support spring 56, the vibration box 3 drives the sieve plate 4 to vibrate, and then the masterbatch is poured into the inner cavity of the vibration box 3 and reaches the top of the sieve plate 4. At this time, the masterbatch that meets the particle size requirements falls from the pores on the surface of the sieve plate 4 to the inner cavity of the silo 2 and enters the inner cavity of the conveying pipe 1, and the driving motor 6 drives the spiral conveying rod 7 to rotate. The spiral conveying rod 7 spirally conveys the masterbatch entering the conveying pipe 1, and the masterbatch retained on the top of the sieve plate 4 slides to the lower right under the action of the inclination angle of the sieve plate 4, and enters the inner cavity of the collecting plate 9 from the discharge trough 8, and then is discharged centrally by the discharge pipe 10.
