Description

Technical Field

[0001] This invention relates to the technical field of cable processing, and more particularly to a three-layer co-extrusion cable processing apparatus. Background Technology

[0002] In the field of cable manufacturing technology, three-layer co-extrusion cable is a common production process. It achieves multiple layers of protection for the cable's outer layer through the sequential extrusion of multiple layers of materials. As an important cable production tool, three-layer co-extrusion cable processing equipment is mainly used for the sequential extrusion molding of multiple layers of materials, thereby producing cable products with special properties. Three-layer co-extrusion cable processing equipment typically consists of two main parts: an extruder and a die head. The extruder is responsible for plasticizing and melting the required materials, while the die head is responsible for extruding and molding these materials into a specific shape.

[0003] The existing three-layer co-extrusion cable processing equipment uses three sets of extruders to inject A and B plastic melts through the three sets of extruders. The melts converge in the die head and are sequentially applied to the cable core in the order of ABA. Although two types of plastic melts are used, three sets of extruders are required, resulting in higher operating costs. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this invention is to provide a three-layer co-extrusion cable processing device, which uses two sets of extruders connected to feed inlet one and feed inlet two, respectively injecting different plastic melts, and connecting them through flow channel one and flow channel three, so that the same plastic melt is used in flow channel one and flow channel three, ultimately achieving three-layer material coating of the cable. This reduces one set of extruders, lowers costs, reduces the factory space occupied, shortens production preparation time, and reduces the workload of workers in preheating and cleaning the machine.

[0006] To achieve the above objectives, the present invention proposes a three-layer co-extrusion cable processing device comprising an extruder and a die head, wherein the extruder is provided in two sets, and the die head is connected to the two sets of extruders. The die head includes a barrel, a first flow channel, a second flow channel, a third flow channel, a first feed port, and a second feed port. The first flow channel is disposed on the surface of the barrel, the second flow channel is disposed on the surface of the barrel, the third flow channel is disposed on the barrel and connected to the first flow channel, and the first and second feed ports are disposed on the barrel, respectively connected to the first and second flow channels, and connected to the extruder.

[0007] In addition, the three-layer co-extruded cable processing apparatus proposed according to the present invention may also have the following additional technical features:

[0008] Specifically, a side cylinder, an outer cylinder, and an inner cylinder are sleeved on one outer side of the extrusion cylinder, the outer cylinder is sleeved on the outside of the side cylinder, and the inner cylinder is disposed on the side of the cylinder body.

[0009] Specifically, the cylindrical body is disposed inside the inner cylinder.

[0010] Specifically, the first feed inlet and the second feed inlet are respectively located on the outer side of the outer cylinder.

[0013] Specifically, an installation block is provided at the connection between the first and second feed inlets and the outer cylinder, and the installation block is embedded in the outer side of the outer cylinder.

[0014] Specifically, a fixing frame is fitted onto the outer side of the outer cylinder, a support plate is provided under the fixing frame, symmetrical support rods are provided under the support plate, and a base plate is provided under the support rods.

[0015] Specifically, the two sets of extruders extrude different materials.

[0017] 1. Significant cost advantages: Reduced equipment investment, operating energy consumption, and maintenance costs;

[0018] 2. High space utilization: Suitable for production environments with limited factory space;

Detailed Implementation

[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0028] The three-layer co-extruded cable processing apparatus of the present invention will now be described with reference to the accompanying drawings.

[0029] like Figure 1-2 As shown, the three-layer co-extrusion cable processing apparatus of this embodiment includes an extruder 1 and a die head 2.

[0030] Among them, extruder 1 is equipped with two sets.

[0031] The die head 2 is connected to two sets of extruders 1. The die head 2 includes a barrel 3, flow channel 1 4, flow channel 2 5, flow channel 3 6, feed inlet 1 7, and feed inlet 2 8.

[0032] Among them, flow channel 1 4 is disposed on the surface of cylinder 3, flow channel 2 5 is disposed on the surface of cylinder 3, flow channel 3 6 is disposed on cylinder 3 and connected to flow channel 1 4, feed inlet 1 7 and feed inlet 2 8 are disposed on cylinder 3, feed inlet 1 7 and feed inlet 2 8 are respectively connected to flow channel 1 4 and flow channel 2 5, and connected to extruder 1.

[0033] Specifically, two sets of extruders 1 are set up, each set of extruders 1 is responsible for extruding a type of material. Extruders 1 are connected to flow channels 1 4 and 2 5 through feed inlet 1 7 and feed inlet 2 8, while flow channel 1 4 and flow channel 3 6 are connected. The cable is inserted into the die head 2 through feed pipe 13. The extruded material flows sequentially through flow channel 1 4, flow channel 2 5 and flow channel 3 6 to the cable and is wrapped around the cable. Since the materials in flow channel 1 4 and flow channel 3 6 are the same, the materials in flow channel 1 4 and flow channel 3 6 are wrapped in two layers on the cable, and the material in flow channel 2 5 is wrapped in the middle, forming a structure similar to ABA.

[0034] In one embodiment of the present invention, such as Figure 2 As shown, a side cylinder 9, an outer cylinder 10, and an inner cylinder 11 are sleeved on the outer side of the extrusion cylinder. The outer cylinder 10 is sleeved on the outer side of the side cylinder 9, and the inner cylinder 11 is located on the side of the cylinder body 3.

[0035] It should be noted that the side cylinder 9, outer cylinder 10 and inner cylinder 11 can be matched according to the diameter requirements of different cables. By adjusting the position and diameter of the inner and outer cylinders 10, precise control of the diameter of different layers of the cable can be achieved. This adjustable design can adapt to the needs of different cable diameters, making the processing more flexible, thereby improving processing efficiency and production adaptability.

[0036] In one embodiment of the present invention, such as Figure 2 As shown, feed inlet 7 and feed inlet 8 are respectively located on the outer side of the outer cylinder 10. A mounting block 15 is provided at the connection between feed inlet 7 and feed inlet 8 and the outer cylinder 10. The mounting block 15 is embedded in the outer side of the outer cylinder 10.

[0037] It should be noted that the mounting block 15 is embedded in the outer side of the outer cylinder 10, which fixes the position of the feed inlet, reduces the possibility of movement and displacement, and improves the stability and reliability of the installation. This design of the mounting block 15 improves the maintainability and flexibility of the equipment, facilitates daily maintenance, extends the service life of the equipment, and also improves production efficiency and safety.

[0038] In one embodiment of the present invention, as shown in FIG. 2, a side plate 12 is provided on the outer side surface of the cylinder 3.

[0039] In one embodiment of the present invention, such as Figure 2 As shown, the end openings of the cylinder 3 are respectively provided with a feed inlet 13 and a discharge outlet 14.

[0040] It should be noted that the cable is inserted into the mold head 2 through the feed port 13 and discharged through the discharge port 14.

[0041] In one embodiment of the present invention, such as Figure 1 As shown, a fixing frame 16 is fitted onto the outer side of the outer cylinder 10, a support plate 17 is provided under the fixing frame 16, support rods 18 are symmetrically provided under the support plate 17, and a base plate 19 is provided under the support rods 18.

[0042] It should be noted that the fixing frame 16 and the support plate 17 are connected to the base plate 19 via the support rod 18, forming a stable structural support system. For example, the support plate 17 and the base plate 19 work together to distribute the pressure on the equipment, reduce the vibration and displacement of the equipment during operation, and make the cable processing process more stable and reliable.

[0043] In one embodiment of the present invention, such as Figure 1 As shown, two sets of extruders 1 extrude different materials.

[0044] In summary, the three-layer co-extrusion cable processing device of this invention uses two sets of extruders connected to feed inlet one and feed inlet two, respectively injecting different plastic melts. The device is connected by flow channel one and flow channel three, so that the same plastic melt is used in flow channel one and flow channel three, ultimately achieving three-layer material coating of the cable. This reduces one set of extruders, lowers costs, reduces the factory space occupied, shortens production preparation time, and reduces the workload of workers in preheating and cleaning the machine.
