Description

Technical Field

[0001] This utility model relates to the field of color masterbatch processing technology, and in particular to a color masterbatch strip extruder for color masterbatch production. Background Technology

[0002] In the field of masterbatch production, masterbatch strips are a key intermediate product, and their quality and production efficiency directly affect the performance and market competitiveness of the final masterbatch product. Currently, traditional masterbatch strip extruder designs have significant limitations. On the one hand, existing extruders have a simple structure, typically equipped with only a single-specification extrusion channel, making it difficult to meet the diverse market demands for masterbatch strips of different thicknesses. When it is necessary to produce masterbatch strips of different diameters or cross-sectional areas, the entire extruder must be replaced. This not only increases equipment downtime and reduces production efficiency, but also raises production costs and operational complexity, limiting the company's ability to respond quickly to market changes. On the other hand, during the extrusion process, especially in the early stages of the extrusion operation, residual material from the previous extrusion may remain inside the extrusion channel, which can easily cause blockages when the extrusion operation continues. In traditional operations, manual clearing of blockages is required before each operation, which is obviously quite troublesome. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a masterbatch extrusion head for masterbatch production. Compared to existing technologies, this extrusion head utilizes multiple extrusion components, which facilitates the switching of masterbatch production for different thicknesses. In addition, the use of hot airflow can prevent clogging in the extrusion section.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A masterbatch extrusion head for masterbatch production includes a forming head with a threaded mounting seat installed on the rear side of the forming head; and an adjustable extrusion mechanism, which includes a T-slot formed on the front side of the forming head, a rectangular opening penetrating the forming head on the rear side wall of the T-slot, a T-strip that can slide left and right in the T-slot, and three sets of extrusion components formed on the T-strip, each set of extrusion components consisting of multiple extrusion nozzles equally spaced on the T-strip.

[0005] Preferably, blocking blocks are fixedly connected to both the left and right sides of the T-shaped strip.

[0006] Preferably, two second threaded mounting ports are provided on the rear sidewall of the T-slot, and multiple first threaded mounting ports are provided on the T-strip, wherein a limit screw is installed on two first threaded mounting ports and the corresponding second threaded mounting ports.

[0007] Preferably, the extrusion orifice diameters within the extrusion assemblies of different groups are different.

[0008] Preferably, a hollow block is fixedly connected to the front side of the forming head. The lower end face of the hollow block is V-shaped, which is composed of a horizontal surface and an inclined surface. A strip-shaped air port communicating with the hollow block is opened on the inclined surface.

[0009] Preferably, a threaded connector is installed at the upper end of the hollow block, and the lower end of the threaded connector communicates with the interior of the hollow block. The threaded connector is used for supplying hot airflow.

[0010] Compared with the prior art, the advantages of this utility model are as follows: 1. The operator pushes the T-strip to slide in the T-slot, so that the required extrusion component corresponds to the rectangular opening, realizing the rapid switching of extrusion of masterbatch strips of different thicknesses, reducing equipment downtime, improving production efficiency, and reducing operation difficulty and cost.

[0011] 2. The blocking blocks on both sides of the T-strip prevent it from dislodging from the T-groove. When switching to the left and right extrusion components, the complete movement of the T-strip can accurately align the first and second threaded mounting ports, thus playing a positioning role and ensuring the accuracy and stability of the switching.

[0012] 3. Before extrusion, connect the external hot air blower to the hollow block through the threaded connector. The hot air will blow out evenly from the strip-shaped air outlet, covering the part to be extruded, heating and melting the residual material inside, avoiding extrusion blockage and ensuring continuous production.

[0014] In the diagram: 1 Forming head, 2 Threaded mounting seat, 3 T-groove, 4 T-strip, 5 Blocking block, 6 Extrusion assembly, 7 First threaded mounting port, 8 Hollow block, 9 Threaded connecting seat, 10 Limiting screw, 11 Rectangular opening, 12 Strip-shaped air port, 13 Second threaded mounting port. Detailed Implementation

[0015] 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.

[0016] Reference Figures 1-3 A masterbatch extrusion head for masterbatch production includes a forming head 1, and a threaded mounting seat 2 is installed on the rear side of the forming head 1. The threaded mounting seat 2 cooperates with the end of an existing extruder to realize threaded connection installation and disassembly.

[0017] The system also includes an adjustable extrusion mechanism, which comprises a T-slot 3 located on the front side of the forming head 1. A rectangular opening 11 penetrating the forming head 1 is provided on the rear side wall of the T-slot 3. A T-shaped strip 4, which can slide left and right, is provided within the T-slot 3. Three sets of extrusion components 6 are provided on the T-slot 4. Each set of extrusion components 6 consists of multiple equally spaced extrusion nozzles on the T-slot 4. The nozzle diameters of the different sets of extrusion components 6 are different. Blocks 5 are fixedly connected to both sides of the T-slot 4. The use of the blocks 5 prevents the T-slot 4 from detaching from the T-slot 3 and also provides a certain positioning function. Figure 1 In this state, if you switch to the left extrusion component 6 or the right extrusion component 6, you only need to move the T-strip 4 completely to the right or completely to the left. At this time, the first threaded mounting port 7 and the second threaded mounting port 13 can be matched. If it is necessary to switch between different thicknesses of masterbatch extrusion, simply adjust the rectangular opening 11 corresponding to the different extrusion components 6. Furthermore, in this design, a sealing rubber gasket is provided on the rear side of the T-shaped strip 4, and an extrusion port and a corresponding first threaded mounting port 7 are also provided on the sealing rubber gasket to ensure the sealing of the extruded part. In addition, the T-shaped strip 4 is made of a thermally conductive material.

[0018] Among them, two second threaded mounting ports 13 are opened on the rear side wall of the T-slot 3, and multiple first threaded mounting ports 7 are opened on the T-strip 4. The two first threaded mounting ports 7 and the corresponding second threaded mounting ports 13 are jointly installed with limit screws 10. The forming head 1 has a hollow block 8 fixedly connected to its front side. The lower end face of the hollow block 8 is V-shaped, consisting of a horizontal surface and an inclined surface. A strip-shaped air port 12 communicating with the hollow block 8 is opened on the inclined surface. A threaded connecting seat 9 is installed at the upper end of the hollow block 8. The lower end of the threaded connecting seat 9 communicates with the interior of the hollow block 8. The threaded connecting seat 9 is used for hot air supply. That is, the threaded connecting seat 9 is connected to the blower end of an external hot air blower through a corresponding threaded connector. The external hot air blower can blow out hot air from the strip-shaped air port 12. This operation can be used during each extrusion operation to heat and melt the residue inside the extrusion port, avoiding extrusion blockage. The strip-shaped air port 12 can achieve a uniform flow distribution effect, completely covering the part to be extruded.

[0019] In this invention, when it is necessary to switch between extrusion of masterbatch strips of different thicknesses, the operator pushes the T-strip 4 to slide left and right in the T-groove 3 on the front side of the forming head 1. By sliding the T-strip 4, the required extrusion component 6 is aligned with the rectangular opening 11. During this process, the blocking blocks 5 fixed on the left and right sides of the T-strip 4 can prevent the T-strip 4 from leaving the T-groove 3 and also play a positioning role (this positioning role is only useful when using the extrusion components 6 on the left and right sides). When switching to the left or right extrusion component 6, the T-strip 4 is moved completely to the right or completely to the left to achieve the correspondence between the first threaded mounting port 7 and the second threaded mounting port 13. After determining the position of the required extrusion component 6, install the limiting screw 10 on the corresponding two first threaded mounting ports 7 and second threaded mounting ports 13 to fix the position of the T-strip 4 and ensure the stability of the extrusion process. Before each extrusion operation, connect the blower end of the external hot air blower to the threaded connector 9 at the upper end of the hollow block 8 via the corresponding threaded connector. Start the external hot air blower; the hot air enters the hollow block 8 through the threaded connector 9 and then is evenly blown out from the strip-shaped air vents 12, which communicate with the interior, on the inclined surface of the hollow block 8. The hot air blown out by the strip-shaped air vents 12 can cover the part to be extruded, heating and melting any remaining material inside the extrusion port to prevent extrusion blockage. It should be noted that in this solution, if deep cleaning of the extrusion port is required, Figure 1 In this state, the extrusion ports inside the left and right extrusion components 6 can be cleaned using external tools, such as a cleaning brush. When the middle extrusion component 6 is adjusted so that its rear part is not blocked by the forming head 1, the extrusion ports inside the extrusion component 6 can be cleaned.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
