[0001] This utility model belongs to the field of color masterbatch processing technology, specifically relating to a color masterbatch processing melt extrusion device. Background Technology

[0002] Masterbatch, also known as color masterbatch or color seed, is a new type of special colorant 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.

[0003] Molten masterbatch material needs to be processed into finished products through components such as extruders and molds. During the extrusion of molten material, the required outlet size of the extruder head varies depending on the mold and production speed. Therefore, it is necessary to adapt the appropriate extruder head according to the situation. Currently, most extruder heads are connected to the extrusion device by bolts or welding, which is inconvenient or impossible to disassemble. Therefore, this application proposes a melt extrusion device for processing masterbatch. Utility Model Content

[0004] The purpose of this utility model is to provide a color masterbatch processing melt extrusion device to solve the problem mentioned in the background art that the extrusion head is mostly connected to the extrusion device by bolts or welding, which makes disassembly inconvenient or impossible.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a color masterbatch processing melt extrusion device, comprising a base plate, a power unit, an extrusion rod, and a material cylinder. The power unit is mounted on the base plate and connected to the extrusion rod. The material cylinder is provided with a feed hole for feeding.

The connector is provided with a second positioning hole that cooperates with the positioning element and is aligned with the first positioning hole.

[0009] Preferably, a funnel-shaped feed cylinder is provided at the feed inlet.

[0010] Preferably, four connecting rods are provided, and the four connecting rods are respectively aligned with the four corners of the extrusion head, and the connecting rods are installed on the connector.

[0011] Preferably, a pad is provided at the connecting plate, and the pad is installed on the joint.

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] like Figures 1-5 As shown in the figure, the present invention provides a color masterbatch processing melt extrusion device, including a base plate 1, a power unit 2, an extrusion rod 3, and a barrel 4. The power unit 2 is mounted on the base plate 1 and is connected to the extrusion rod 3. The power unit 2 is a servo motor and can drive the extrusion rod 3 to rotate. The part of the extrusion rod 3 corresponding to the part inside the barrel 4 is provided with spirally distributed blades. When the extrusion rod 3 rotates, it can drive the blades to rotate, thereby pushing the material after the color masterbatch is melted in the barrel 4 to move, and finally pushing the material after the color masterbatch is melted out from the extrusion head 7. The power unit 2 and the extrusion rod 3 can be connected by a commonly used coupling.

[0029] Specifically, a feed hole for feeding is provided at the material cylinder 4, and a funnel-shaped feed cylinder 5 is provided at the feed hole.

[0030] To facilitate the replacement and assembly of the extruder head 7, a connector 6 is provided at the outlet end of the barrel 4 for material discharge. The connector 6 is fixedly connected to the barrel 4 by bolts, and a detachable extruder head 7 is provided at the connector 6 for extruding the molten masterbatch material.

[0031] Specifically, the connector 6 is provided with a connecting rod 8 and a connecting plate 9 for connecting to the extrusion head 7 and providing guidance and positioning. There are four connecting rods 8, and the four connecting rods 8 are respectively aligned with the four corners of the extrusion head 7. The connecting rods 8 are installed on the connector 6. The connecting plate 9 is provided with a pad 10, and the pad 10 is installed on the connector 6.

[0032] More specifically, the connector 6 is provided with a positioning element 11 for fixing and loosening the connection between the connector 6 and the extrusion head 7. The extrusion head 7 is provided with a first positioning hole that cooperates with the positioning element 11 and is perpendicular to the connecting rod 8. The connector 6 is provided with a second positioning hole that cooperates with the positioning element 11 and is aligned with the first positioning hole. The positioning element 11 can be connected to the first positioning hole and the second positioning hole by plugging or by threading.

[0033] The extruder head 7 and the connector 6 are connected by a plug-in connection. During the process of inserting the extruder head 7 into the connector 6, the corresponding parts of the connecting rod 8 and the connecting plate 9 need to be aligned with the extruder head 7. The extruder head 7 is slowly pushed until it is fully inserted into the connector 6. At this time, the extruder head 7 and the connector 6 can only slide relative to each other from left to right. Then, the positioning part 11 is inserted into the extruder head 7 and the connector 6. The positioning part 11 is inserted into the extruder head 7 and the connector 6 from a direction perpendicular to the connecting rod 8 and the connecting plate 9, which restricts the tendency of the extruder head 7 and the connector 6 to move relative to each other from left to right. In this way, the assembly work between the extruder head 7 and the connector 6 is completed. When the extruder head 7 and the connector 6 are connected, the connecting rod 8, the connecting plate 9 and other components guide the movement of the extruder head 7 during installation and disassembly, which is relatively smooth. Moreover, the installation and disassembly of the extruder head 7 can be achieved by simply inserting and pulling the corresponding parts. There are only two steps, so the installation and disassembly of the extruder head 7 is relatively convenient.

[0034] To prevent the positioning component 11 from becoming loose during use of the extruder head 7, a locking assembly 12 for locking and releasing the positioning component 11 is provided at the extruder head 7. The locking assembly 12 includes a locking block 1201 perpendicular to the positioning component 11, a locking box 1202 that slides with the locking block 1201, a push-pull rod 1203 mounted on the locking block 1201 for easy manual pushing and pulling, and a spring 1204 that assists in the movement of the locking block 1201. The spring 1204 is a metal spring with a length of 5cm and a wire diameter of 6mm.

[0035] Specifically, the locking box 1202 is provided with a guide groove, which cooperates with the push-pull rod 1203, and the positioning component 11 is provided with a locking groove that matches the locking block 1201.

[0036] The locking component 12 can lock the position of the positioning member 11, mainly after the positioning member 11 is inserted into the extruder head 7 and the connector 6, to prevent the positioning member 11 from loosening during the use of the extruder head 7.

[0037] For reference Figure 5The connector 6 has a conical section on one side, and the extruder 7 has a conical groove that mates with the conical section. The channels inside the connector 6 and the extruder 7 are connected through the conical section and the conical groove. The conical section and the conical groove can increase the contact area at the connection between the connector 6 and the extruder 7, improve the sealing performance at the connection between the connector 6 and the extruder 7, and prevent the molten masterbatch material from leaking from the connector 6 and the extruder 7.

[0038] In summary, this utility model provides a masterbatch processing melt extrusion device. The extruder head 7 and the connector 6 are connected by an insertion method. During the process of inserting the extruder head 7 into the connector 6, the connecting rod 8 and the connecting plate 9 need to be aligned with the corresponding parts of the extruder head 7. The extruder head 7 is slowly pushed until it is fully inserted into the connector 6. At this time, the extruder head 7 and the connector 6 can only slide relative to each other left and right. Then, the positioning member 11 is inserted into the extruder head 7 and the connector 6. The positioning member 11 is inserted into the extruder head 7 and the connector 6 from a direction perpendicular to the connecting rod 8 and the connecting plate 9, which restricts the tendency of the extruder head 7 and the connector 6 to move relative to each other left and right. In this way, the assembly work between the extruder head 7 and the connector 6 is completed. When the extruder head 7 and the connector 6 are connected, the connecting rod 8, the connecting plate 9 and other components guide the movement of the extruder head 7 during installation and disassembly, which is relatively smooth. Moreover, the installation and disassembly of the extruder head 7 can be achieved by simply inserting and pulling the corresponding components. There are only two steps, so the installation and disassembly of the extruder head 7 is relatively convenient.

[0039] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
