DETAILED DESCRIPTION

[0026] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0027] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0030] Example 1

[0031] Please refer to Figure 1 、 Figure 3 and Figure 6 The top of the mixing chamber 1 is fixed with a motor 2, and the output end of the motor 2 passes through the mixing chamber 1 and is fixedly connected to the rotating shaft 5. A plurality of groups of No. 1 mixing groups are provided below the circumferential side of the rotating shaft 5. The No. 1 mixing group includes a plurality of No. 1 guide members equidistantly arranged on the circumferential side of the rotating shaft 5. The No. 1 guide member is used to guide the plastic masterbatch upward from the bottom. A plurality of groups of No. 2 mixing groups are provided above the circumferential side of the rotating shaft 5. The No. 2 mixing group includes a plurality of No. 2 guide members equidistantly arranged on the circumferential side of the rotating shaft 5. The No. 2 guide member is used to guide the upper plastic masterbatch downward. A blocking member is provided between the plurality of No. 1 mixing groups and the plurality of No. 2 mixing groups. A plurality of rotating assemblies 9 are equidistantly provided inside the blocking member. The rotating assembly 9 is used to block the plastic masterbatch flowing in the middle, and a plurality of transmission members are equidistantly provided on the outside of the rotating assembly 9.

[0032] Further, such as Figure 2 and Figure 3As shown, the plurality of No. 1 guide members include a plurality of No. 1 guide plates 61 equidistantly and obliquely fixed to the circumferential side of the rotating shaft 5. The No. 1 guide plates 61 are used to drive the plastic masterbatch to flip upward in accordance with the inclination angle and the rotation of the rotating shaft 5. A No. 1 guide groove 62 is provided in the middle of the No. 1 guide plate 61, which is connected to the upper and lower ends of the No. 1 guide plate 61 and is narrow at the top and wide at the bottom. The No. 1 guide groove 62 is used to allow the masterbatch to pass through when the rotating shaft 5 rotates, thereby reducing the direct friction between the No. 1 guide plate 61 and the plastic masterbatch, reducing the energy consumption of the motor 2, and promoting cross-mixing between the plastic masterbatch.

[0033] When the motor 2 rotates in the opposite direction to drive the rotating shaft 5 to rotate, the guide plate No. 1 61 can be tilted at an angle, so that its original function of driving the plastic masterbatch to flip upward is reversed. The reverse rotation of the rotating shaft 5 drives the plastic masterbatch to be guided downward. While accelerating the plastic masterbatch to pass through the discharge component 3 downward, the plastic masterbatch can also enter the interior of the guide groove No. 1 62 through the wider bottom end of the guide groove No. 1 62. The plastic masterbatch is guided to the narrower end of the top through the narrow upper and wider lower structure, so that the plastic masterbatch is cross-mixed again.

[0034] Further, such as Figure 2 and Figure 3 As shown, several No. 2 guide members include several No. 2 guide plates 71 that are equidistant and obliquely fixed on the circumferential side of the rotating shaft 5. The inclination angle of the No. 2 guide plate 71 is opposite to that of the No. 1 guide plate 61. When the rotating shaft 5 rotates, the No. 2 guide plate 71 drives the upper plastic masterbatch to guide downward through the inclination angle, thereby cooperating with the No. 1 guide plate 61 to make the plastic masterbatch gather and contact in the middle of the mixing chamber 1 for mixing. A No. 2 guide groove 72 is provided in the middle of the No. 2 guide plate 71, which is connected to the upper and lower ends of the No. 2 guide plate 71 and is narrow at the top and wide at the bottom. The No. 2 guide groove 72 is used to cooperate with the rotation of the No. 2 guide plate 71, so that the upper plastic masterbatch passes through the wider position at the bottom of the No. 2 guide groove 72, thereby driving the plastic masterbatch to be guided to the narrower area at the top of the No. 2 guide groove 72, so that the plastic masterbatch is squeezed to the middle and passes through the inside of the No. 2 guide groove 72, thereby promoting cross-mixing of the plastic masterbatch above.

[0035] Example 2

[0036] The plastic processing masterbatch mixing device provided in Example 1 is further optimized, specifically, as Figure 3 and Figure 5As shown, the blocking member includes a blocking ring 8 fixed in the middle of the inner wall of the mixing chamber 1. A funnel located on one side of the motor 2 is provided at the top of the mixing chamber 1. The interior of the funnel is connected to the interior of the mixing chamber 1. The plastic masterbatch, pigment, filler, etc. that need to be stirred are added to the interior of the mixing chamber 1 through the funnel. The upper and lower ends of the blocking ring 8 are inclined inward. When the plastic masterbatch is gathered to the middle through the No. 1 guide plate 61 and the No. 2 guide plate 71, it is blocked by the blocking ring 8 and guided to the middle along the inward inclined surface, so that the plastic masterbatch is further gathered and mixed in the middle of the mixing chamber 1.

[0037] Further, such as Figure 3 、 Figure 5 and Figure 6 As shown, several rotating components 9 include several support cylinders 91 equidistantly fixed on the inner wall of the blocking ring 8, and the support cylinder 91 is used to increase the stability of the connection between the conical column 92 and the blocking ring 8, so that the plastic masterbatch will not directly hit the end of the conical column 92 close to the blocking ring 8. The interior of the support cylinder 91 is provided with a conical column 92 rotatably connected to the blocking ring 8. The conical column 92 is used to make the plastic masterbatch gather inside the blocking ring 8, and then cooperate with the fluidity driven by the rotating shaft 5, the first guide plate 61 and the second guide plate 71 to make the plastic masterbatch continuously hit the support cylinder 91, and the plastic masterbatch is guided to the area away from the middle through the conical surface of the support cylinder 91, thereby further increasing the complexity of the mixed flow and improving the mixing effect.

[0038] Further, such as Figure 6 As shown, several transmission parts include several transmission plates 10 fixed at equal distances on the circumferential side of the conical column 92. The transmission plates 10 are used to increase the contact area and friction with the plastic masterbatch, which helps to break the stable trend of the plastic masterbatch during the flow process and increase the internal turbulence, thereby improving the mixing effect. When the plastic masterbatch hits the transmission plate 10, the impact force is used to drive the conical column 92 to rotate, thereby reducing the impact force caused by the impact, thereby extending the service life of the conical column 92.

[0039] Example 3

[0040] The plastic processing masterbatch mixing device provided in Example 1 and Example 2 is further optimized, such as Figure 1 、 Figure 2 and Figure 3 As shown, the unloading component 3 includes a bottom plate 31 fixed to the bottom end of the mixing bin 1. The plastic masterbatch added to the inside of the mixing bin 1 will contact the bottom plate 31. A discharge port 32 is fixedly opened on the bottom plate 31. An electric switch valve is provided inside the discharge port 32. By opening the electric switch valve, the plastic masterbatch falls into the collecting component 4 through the discharge port 32. The rotating shaft 5 is rotatably connected to the bottom plate 31.

[0041] Further, such as Figure 1 and Figure 2 As shown, the collecting assembly 4 includes a supporting frame 41 fixed to the bottom end of the base plate 31, and the front of the bottom end of the support frame 41 is tilted downward, so as to allow the plastic masterbatch to flow to the outlet at the front end of the support frame 41 at an inclined angle. A guide frame 42 that is wider at the back and narrower at the front is fixed to the front end of the support frame 41, so as to guide the plastic masterbatch to the middle of the front end. The interior of the guide frame 42 is connected to the interior of the support frame 41, and the front end of the guide frame 42 is tilted downward. A support seat 43 is provided at the bottom end of the support frame 41.

[0042] The use process of the plastic processing masterbatch mixing device provided by the utility model is as follows:

[0043] When it is necessary to stir the plastic masterbatch inside the mixing bin 1, the motor 2 is started to drive the rotating shaft 5 to rotate, so that the No. 1 guide plates 61 and the No. 2 guide plates 71 rotate around the rotating shaft 5, thereby driving the plastic masterbatch below to be guided upward by the No. 1 guide plate 61, and driving the plastic masterbatch above to be guided downward by the No. 2 guide plate 71, so that the plastic masterbatch is contacted and mixed in the middle, and the plastic masterbatch passes through the No. 1 guide groove 62 and the No. 2 guide groove 72 to promote its cross-mixing. After the plastic masterbatch passes through the middle, the material is guided to the inside of the blocking ring 8 by the blocking ring 8, thereby cooperating with the No. 2 guide plate 71 and the No. 1 guide plate 61 to drive the fluidity of the plastic masterbatch, so that it hits the support cylinder 91, the conical column 92 and the transmission plate 10, and the transmission plate 10 drives the conical column 92 to rotate while increasing the contact area with the material, further increasing the internal turbulence, thereby improving the mixing effect;

[0044] When the material needs to be taken out of the mixing bin 1 through the discharge assembly 3, the electric switch valve inside the discharge port 32 is opened to allow the material to fall through the inside of the discharge port 32 to the inside of the support frame 41, and then flow out through the guide frame 42. During the process, the motor 2 can be started to drive the rotating shaft 5 to rotate in the opposite direction, so that the No. 1 guide plate 61 guides the material downward at an inclined angle, thereby increasing the discharge speed and performing the final mixing of the material.
