Description

Technical Field

[0001] This utility model relates to the field of color masterbatch processing equipment, and in particular to a color masterbatch pigment mixing device. Background Technology

[0002] Masterbatch, also known as colorant or colorant granules, is a new type of colorant specifically for polymer materials, also called pigment preparation. Masterbatch is mainly used in plastics. It consists of three basic elements: pigment or dye, carrier, and additives. It is an aggregate made by uniformly loading an extraordinary amount of pigment into resin, and can be called a pigment concentrate, therefore its coloring power is higher than that of the pigment itself. During processing, a small amount of masterbatch is mixed with uncolored resin to achieve the designed pigment concentration in the resin or product.

[0003] In melt spinning, color masterbatch is added to achieve the desired fiber color, as described in Chinese Patent Application Publication No. CN115537953A. The prepared color masterbatch pigment exhibits good colorfastness and increases the uniformity of dyeing. Before producing this color masterbatch pigment composition using a twin-screw extruder, the raw materials for the color masterbatch pigment, carrier resin, and other raw materials need to be mixed to ensure a homogeneous mixture. Typically, the raw materials for the color masterbatch pigment are mixed by placing them in a barrel and then stirring them with a stirring device to achieve uniform mixing. However, the stirring shaft of the stirring device needs to penetrate the barrel shell. After a period of use, the seal between the stirring shaft and the barrel shell may fail, causing material leakage and affecting material mixing. This requires improvement. Utility Model Content

[0004] To address the potential material leakage issue during mixing, this application provides a masterbatch pigment mixing apparatus.

[0005] The color masterbatch and pigment mixing device provided in this application adopts the following technical solution:

[0009] Preferably, the fixing component includes a fixing buckle and a fixing hook. The fixing hook is fixed to both sides of the fixing cover. The loading seat is provided with an installation block. The fixing buckle includes a fixing seat fixed to the installation block, a rotating block rotatably connected to the fixing seat, and a fixing ring rotatably connected to the rotating block. When the rotating block is flipped to fit the fixing seat, the fixing ring hooks onto the fixing hook to fix the fixing cover to the loading seat.

[0010] Preferably, a plug-in plate is fixed on the fixed base, a plug-in hole is provided on the rotating block for the plug-in plate to pass through, and a locking hole is provided on the plug-in plate.

[0013] The main technical effects of this utility model are reflected in the following aspects:

[0014] 1. This utility model sets up a material cylinder to be placed inside the material cylinder, which is fixed on the feeding seat. Several material cylinders rotate with the rotating seat, thereby shaking and mixing the material. Since the cylinder body and the cover body are tightly connected by connecting protrusions and connecting grooves, leakage of material during mixing can be effectively prevented.

[0015] 2. This utility model adds a rotating motor inside the rotating seat to drive the feeding seat to rotate, so that the feeding seat rotates itself and drives the material cylinder to rotate. While the material cylinder revolves around the revolution, it maintains its own rotation to assist in mixing and make the materials completely mixed.

[0016] 3. This utility model improves the leak-proof function of the material cylinder by setting a sealing ring on the groove wall of the mounting groove to improve the tightness of the connection between the cylinder and the cover. Attached Figure Description

Detailed Implementation

[0022] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0023] This application discloses a color masterbatch pigment mixing device.

[0024] Reference Figure 1 This embodiment of a masterbatch pigment mixing device includes a base 1, a rotating seat 2 rotatably connected to the base 1, several feeding seats 3 mounted on the outer peripheral wall of the rotating seat 2, a material cylinder 4 mounted on the feeding seats 3, a fixed cover 5 mounted on the feeding seats 3, and a drive motor (not shown in the figure) fixed inside the base 1. The rotation axis of the rotating seat 2 is horizontal. The drive motor drives the rotating seat 2 to rotate. A reduction gearbox structure is also installed inside the base 1 to assist the drive motor in driving the rotating seat 2. In this embodiment, there are six feeding seats 3 and six material cylinders 4. The appropriate number of feeding seats 3 and material cylinders 4 can be selected as needed for material mixing.

[0025] Reference Figure 1 and Figure 2 The material cylinder 4 includes a cylinder body 41 and a cover body 42. A connecting protrusion 6 is fixed on the side of the cylinder body 41 facing the cover body 42, and a connecting groove 7 is provided on the side of the cover body 42 facing the cylinder body 41 for the connecting protrusion 6 to be inserted. Six feeding seats 3 are equally spaced and installed on the outer peripheral wall of the rotating seat 2. The feeding seats 3 are rotatably connected to the rotating seat 2. Several rotating motors (not shown in the figure) are installed inside the rotating seat. Each rotating motor corresponds to one feeding seat 3 (six motors are installed). The output shaft of the rotating motor is fixed to the feeding seat 3, and the rotating motor drives the feeding seat 3 to rotate.

[0026] Reference Figure 2 and Figure 3 The feeding seat 3 has an installation cavity 8, and the material cylinder 4 is placed in the installation cavity 8. A positioning protrusion 9 is fixed on the bottom wall of the feeding seat 3 and the opposite side of the fixing cover 5. Positioning grooves 10 are provided on both end faces of the material cylinder 4 to accommodate the positioning protrusion 9. The cooperation between the positioning protrusion 9 and the positioning grooves 10 facilitates the installation of the material cylinder 4 and also serves as the rotation axis of the material cylinder 4 (the two positioning protrusions 9 on the bottom wall of the feeding seat 3 and the fixing cover 5) so that the material cylinder 4 is driven to rotate due to centrifugal force. While the rotating seat 2 drives the material cylinder 4 to rotate, the material cylinder 4 can also rotate to a certain extent to improve the mixing effect.

[0027] Reference Figure 1 and Figure 4 A fixing component 11 is installed on the feeding seat 3. The fixing component 11 is used to fix the fixing cover 5 to the feeding seat 3 to fix the material cylinder 4. The fixing component 11 includes a fixing buckle 111 and a fixing hook 112. The fixing hook 112 is fixed to both sides of the fixing cover 5. An installation block 12 is fixed on the feeding seat 3. The fixing buckle 111 includes a fixing seat 1111 fixed to the installation block 12, a rotating block 1112 rotatably connected to the fixing seat 1111, and a fixing ring 1113 rotatably connected to the rotating block 1112. When the rotating block 1112 is flipped to fit the fixing seat 1111, the fixing ring 1113 hooks onto the fixing hook 112 to fix the fixing cover 5 to the feeding seat 3.

[0028] Reference Figure 1 and Figure 4 A connector plate 13 is fixed on the fixed base 1111. The rotating block 1112 has a connector hole 14 for the connector plate 13 to pass through. The connector plate 13 has a locking hole 15. The locking hole 15 can be fitted with a round rod or a lock to fix the rotating block 1112 to the fixed base 1111. A torsion spring 20 is also installed on the fixed base 1111. The torsion spring 20 can make the rotating block 1112 tend to abut against the fixed base 1111.

[0029] Reference Figure 2 The material cylinder 4 has a material cavity 17 for material to be contained. A sealing ring 19 is placed on the groove wall of the connecting groove 7, and the inner wall of the sealing ring 19 abuts against the outer wall of the connecting protrusion 6.
