Description

Technical Field

[0001] This utility model relates to the field of masterbatch dispersion equipment, and in particular to a masterbatch pre-dispersion device. Background Technology

[0002] Color masterbatch is a pigment concentrate, mainly used in the coloring of industrial products such as plastics, fibers, and printing inks. Color masterbatch is composed of carrier resin and pigment, and sometimes some additives are added. The use of color masterbatch can improve the uniformity and stability of product coloring, while reducing the impact of pigment on product performance.

[0003] Color masterbatch is usually in the form of columnar or irregular particles. When using it, the appropriate amount of different color masterbatch is selected and added according to the needs. However, the storage requirements of color masterbatch are relatively strict, and there is a high probability that it will stick together. Sticky color masterbatch will prolong the coloring process of the product after being added, and uneven coloring is likely to occur after the process is completed, which may even lead to the need for secondary processing. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to solve the problem that color masterbatch particles are prone to clumping during storage and use. When clumped color materials are added to products, the coloring process is prolonged, and uneven coloring and color difference occur after the product is processed, resulting in waste or secondary processing.

[0005] To solve the problems of the prior art, the technical solution of this utility model is as follows: A color masterbatch pre-dispersion device includes an injection pipe and a discharge pipe arranged in opposite directions. The bottom of the injection pipe is provided with a spherical cavity covering the top of the discharge pipe. The end of the top of the discharge pipe located inside the spherical cavity is provided with a collection chamber. The surface of the spherical cavity is provided with an annular protrusion. The inner wall of the annular protrusion is arranged with conical hairs in an annular array. The surface of the collection chamber is provided with a sieve hole in an annular shape. There are several groups of sieve holes. Each group of sieve holes has several holes and the diameter gradually increases from top to bottom. A baffle is provided between every two groups of sieve holes. Each baffle is provided with a conical protrusion on the side near the annular protrusion.

[0006] Furthermore, the bottom of the spherical cavity abuts against the surface of the discharge pipe, and there is a uniform gap between the spherical cavity and the collection chamber to ensure that the spherical cavity is sealed and the internal material will not escape outward, and the gap between the spherical cavity and the collection chamber can accommodate a sufficient amount of material to enter.

[0007] Furthermore, the annular protrusion is positioned parallel to the center of the spherical cavity on its surface and is connected to the spherical cavity, creating an annular groove on the inner wall of the spherical cavity to provide a storage space for materials.

[0008] Furthermore, the conical bristles are made of hard rubber with a conical structure at the end that is smaller than the bottom diameter, and the hardness of the conical bristles decreases as the diameter decreases. When in contact with the material, the conical bristles can provide sufficient support to support the material.

[0009] Furthermore, the sieve holes are rectangular perforations vertically opened on the surface of the collection chamber, and several sets of sieve holes are spirally distributed on the surface of the collection chamber, connecting the collection chamber and the spherical cavity through the sieve holes.

[0010] Furthermore, the lever is a sheet-like structure made of rubber, and the hardness of the lever gradually decreases from the connection point with the collection bin to the other side, so as to avoid excessive contact between the lever and the material, which could cause excessive damage to the material.

[0011] Furthermore, the top of the dial plate is provided with an upwardly extending portion that extends into the injection tube, allowing the dial plate to contact the material immediately.

[0012] Furthermore, the conical protrusion extends to the annular groove inside the spherical cavity, and the conical protrusion abuts against the conical hair end, shortening the distance between the conical protrusion and the conical hair, so that the conical protrusion can push the material closer to the conical hair.

[0013] Furthermore, the discharge pipe is connected to an external power unit and rotates horizontally in the axial direction.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] This invention uses an external power device to drive the discharge pipe to rotate, thereby causing the collection bin and its surface structure to rotate as well. During this process, the top of the agitator plate first contacts the material injected into the injection pipe, breaking up any oversized material. The remaining material then enters the gap between the spherical cavity and the collection bin along the agitator plate and enters the annular protrusion. Subsequently, the material is simultaneously crushed and dispersed by the pressure of the conical bristles and the conical protrusion on both sides. The dispersed material then enters the discharge pipe through the sieve holes on the surface of the collection bin and is discharged outwards. During this process, the material is completely dispersed and will not enter the product in a clumping manner. Furthermore, during the dispersion process, materials of different colors will be mixed evenly, shortening the product processing speed. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figure 1-4 As shown, a color masterbatch pre-dispersion device includes an injection pipe 1 and an discharge pipe 2 arranged opposite to each other. The discharge pipe 2 is connected to an external power device and rotates horizontally in the axial direction. The bottom of the injection pipe 1 is provided with a spherical cavity 3 covering the top of the discharge pipe 2. The top of the discharge pipe 2 is provided with a collection chamber 4 at the end inside the spherical cavity 3. The bottom of the spherical cavity 3 abuts against the surface of the discharge pipe 2, and there is a uniform gap between the spherical cavity 3 and the collection chamber 4 to ensure that the spherical cavity 3 is sealed and the internal material will not escape outward. The gap between the spherical cavity 3 and the collection chamber 4 can accommodate a sufficient amount of material to enter.

[0023] The surface of the spherical cavity 3 is provided with an annular protrusion 5, which is located on the surface of the spherical cavity 3 parallel to the center and is connected to the spherical cavity 3, so that the inner wall of the spherical cavity 3 presents an annular groove, providing a storage space for materials. The inner wall of the annular protrusion 5 is arranged with conical hairs 6 in an annular array. The conical hairs 6 are made of hard rubber with a conical structure at the end diameter smaller than the bottom diameter, and the hardness of the conical hairs 6 decreases as the diameter decreases. When in contact with materials, the conical hairs 6 can provide sufficient support to support the materials.

[0024] The surface of the collection chamber 4 is provided with a ring of screen holes 7. The screen holes 7 are rectangular perforations that are vertically opened on the surface of the collection chamber 4. Several sets of screen holes 7 are spirally distributed on the surface of the collection chamber 4. The collection chamber 4 and the spherical cavity 3 are connected through the screen holes 7. There are several sets of screen holes 7, and each set of screen holes 7 has several holes and the diameter gradually increases from top to bottom. A deflector 8 is provided between every two sets of screen holes 7. The deflector 8 is a sheet structure made of rubber. The hardness of the deflector 8 gradually decreases from the connection with the collection chamber 4 to the other side to avoid excessive contact between the deflector 8 and the material, which would cause excessive damage to the material. The top of the deflector 8 is provided with an upward extension part that extends into the inside of the injection pipe 1, so that the deflector 8 can contact the material immediately. Each deflector 8 is provided with a conical protrusion 9 on the side near the annular protrusion 5. The end of the conical protrusion 9 extends into the annular groove of the annular protrusion 5 located in the spherical cavity 3, and the end of the conical protrusion 9 abuts against the end of the conical bristle 6, shortening the distance between the conical protrusion 9 and the conical bristle 6, so that the conical protrusion 9 can push the material closer to the conical bristle 6.

[0025] Working principle description: First, the discharge pipe 2 is rotated by an external device. During the rotation of the discharge pipe 2, the collection bin 4 and the deflector plate 8 on the surface of the collection bin 4 rotate accordingly. Then, the operator puts the material in through the injection pipe 1. After the material enters the injection pipe 1, it first contacts the top of the deflector plate 8. The rotating deflector plate 8 breaks up the clumps of material. Then, the material of the same size enters the position between the spherical cavity 3 and the collection bin 4. During this process, the smaller material will directly pass through the screen hole 7 and enter the collection bin 4 and be discharged outward along the discharge pipe 2, while the larger material continues to move until it enters the position of the annular protrusion 5 and contacts the conical bristles 6. At this time, the conical protrusion 9 on the surface of the rotating deflector plate 8 moves with the deflector plate 8 and approaches the conical bristles 6. When the conical protrusion 9 enters the conical bristles 6, it contacts the material and strikes the material. When the material is struck by the conical protrusion 9, the conical bristles 6 provide a certain support for the material and assist the material in bearing the force. The material is further broken and dispersed by the impact of the conical protrusion 9. The dispersed material passes through the screen hole 7 again and enters the collection bin 4 and is discharged outward along the discharge pipe 2. The material discharged from the discharge pipe 2 can be used directly.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
