Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of double - color insulation extrusion, and particularly relates to a single - layer double - color insulation extrusion diverter. Background Technique
[0002] The statements in this part only provide background technical information related to the present disclosure and do not necessarily constitute prior art.
[0003] With the continuous intensification of competition in the wire and cable industry, higher performance requirements are imposed on wire and cable products, which are forcing wire and cable enterprises to innovate and improve in product materials, structures, performances, and even appearances. Home - decoration wiring is one such product. Wiring has a huge market capacity in any region, and the production technology requirements for the product are not high, which has led to a large number of related production enterprises and extra - fierce competition. If an enterprise wants to stand out in the competition, in addition to the quality of the product itself, innovation in product structure or appearance is also necessary.
[0004] The insulation colors of conventional wiring products are generally yellow, green, red, blue, and yellow - green. Basically, they are all single - color products. For the yellow - green color, it is only mainly yellow or green with an additional strip of another color. In addition, due to the need to produce yellow - green wiring, generally two heads are configured on one production line. If only single - color wires are produced, one of the heads will be idle, and the equipment efficiency cannot be fully utilized. Secondly, for double - color insulation, color - changing and discharging are generally required, which is likely to cause waste of raw materials. Content of the Utility Model
[0005] In order to solve the technical problems existing in the prior art, the utility model provides a single - layer double - color insulation extrusion diverter. With the help of this diverter, while extruding one color on the inner layer of the wiring, another color can be extruded additionally on the outer layer, which can effectively improve the product identification degree, reduce the waste caused by color - changing and discharging, and also give full play to the production equipment efficiency.
[0006] To achieve the above object, the utility model is realized by the following technical solutions:
[0007] A single-layer double-color insulation extrusion diverter, comprising a cylinder. A die core channel is provided inside the cylinder. The outside of the cylinder includes a feeding part and a covering part above it. A feeding port is provided on the side wall of the feeding part. On both sides of the feeding port, a first confluence channel and a second confluence channel branch out in opposite directions. After the first confluence channel extends along the circumference of the cylinder for a certain length, it turns vertically. At the turning point of the first confluence channel, a first branch channel and a third branch channel branch out along the side wall of the cylinder to both sides. After the second confluence channel extends along the circumference of the cylinder for a certain length, it turns vertically. At the turning point of the second confluence channel, a second branch channel and a fourth branch channel branch out along the side wall of the cylinder to both sides. The first branch channel and the second branch channel, and the third branch channel and the fourth branch channel intersect and communicate with each other.
[0008] Further technical solution: The die core channel is embedded in a tapered groove provided inside the cylinder. Both ends of the tapered groove are open, and a die sleeve channel is tightly fixed to the small opening end of the tapered groove.
[0009] Further technical solution: The die core channel is a die core part with one end tapered and the other end cylindrical, and a channel for a conductor to pass through is provided inside it.
[0010] Further technical solution: The tapered end of the die core channel penetrates into the die sleeve channel. The inside of the die sleeve channel is hollow, and the inner layer color insulating material and the outer layer color insulating material flow in successively.
[0011] Further technical solution: The first branch channel extends obliquely upward from the turning point of the first confluence channel to the front side wall of the feeding part.
[0012] Further technical solution: The third branch channel extends obliquely upward from the turning point of the first confluence channel to the rear side wall of the feeding part.
[0013] Further technical solution: The first branch channel and the third branch channel form a certain included angle.
[0014] Further technical solution: The second branch channel extends obliquely upward from the turning point of the second confluence channel to the front side wall of the feeding part.
[0015] Further technical solution: The fourth branch channel extends obliquely upward from the turning point of the second confluence channel to the rear side wall of the feeding part.
[0016] Further technical solution: The second branch channel and the fourth branch channel form a certain included angle.
[0017] The beneficial effects of the present utility model:
[0018] The utility model can extrude a color on the inner layer of the cloth wire and simultaneously extrude another color on the outer layer, achieving the effect of simultaneous extrusion of double color layers, effectively improving the product identification degree, and realizing the innovation in the structure and appearance of the cloth wire product. At the same time, the production cost can be reduced to a certain extent. After fixing the inner layer color, there is no need to change the color and discharge the material, which can avoid the waste caused by color change and discharge, and reduce the input cost of raw materials.
[0019] The utility model is mainly used for single-layer double-color insulation extrusion, which can be used for color ring wire or color skin wire extrusion. Different from conventional double-color extrusion, it does not only extrude a color band, but directly extrudes a color layer.
[0020] The utility model can effectively improve the production efficiency of the equipment. During the use of the diverter, two machine heads must be used simultaneously, which can effectively avoid the waste of production capacity caused by equipment idleness. Description of the Drawings

Detailed Embodiment
[0028] The following further describes the utility model in conjunction with the drawings and specific embodiments.
[0029] See Figure 1As shown in the figure, an embodiment of the present utility model provides a single-layer double-color insulation extrusion diverter, which includes a column body. A die core channel 4 is provided inside the column body. The outside of the column body includes a feeding part 2 and a covering part 3 above it. A feeding port 1 is provided on the side wall of the feeding part 2. A first confluence channel 5 and a second confluence channel 6 branch out in opposite directions on both sides of the feeding port 1. After the first confluence channel 5 extends along the circumference of the column body for a certain length, it turns vertically. At the turning point of the first confluence channel 5, a first branch channel 7 and a third branch channel 9 branch out along the side wall of the column body to both sides. After the second confluence channel 6 extends along the circumference of the column body for a certain length, it turns vertically. At the turning point of the second confluence channel 6, a second branch channel 8 and a fourth branch channel 10 branch out along the side wall of the column body to both sides. The first branch channel 7 and the second branch channel 8, and the third branch channel 9 and the fourth branch channel 10 intersect and communicate with each other.
[0030] In this embodiment, the diameter of the feeding part 2 is larger than that of the covering part 3, that is, the upper part of the diverter has a smaller diameter and the lower part has a wider diameter, which is convenient for the outer layer color insulating material to spread from the feeding port towards the covering part.
[0031] In this embodiment, the feeding port 1 is provided on the front side wall of the feeding part 2 at a certain position from the bottom side and is at the center position of the side wall, which is convenient for the uniformity of subsequent insulation material diversion.
[0032] In this embodiment, as Figure 1 、 2 shown, the first confluence channel 5 and the second confluence channel 6 are narrow and deep, which can more effectively guide the flow of the insulating material; in some embodiments, the first confluence channel 5 and the second confluence channel 6 extend in opposite directions and turn vertically when extending to the central axes of the side walls on both sides of the feeding part 2.
[0033] As Figure 3 shown, at the turning point of the first confluence channel 5, a first branch channel 7 and a third branch channel 9 branch out along the side wall of the column body to both sides. The first branch channel 7 extends obliquely upward from the turning point of the first confluence channel 5 to the front side wall of the feeding part 2 and extends obliquely upward to the upper right along the arc-shaped side wall of the feeding part. The third branch channel 9 extends obliquely upward from the turning point of the first confluence channel 5 to the rear side wall of the feeding part 2 and extends obliquely upward to the upper left along the arc-shaped side wall of the feeding part. The first branch channel 7 and the third branch channel 9 form a certain included angle.
[0034] As Figure 4As shown in the figure, at the turning point of the second confluence channel 6, the second branch channel 8 and the fourth branch channel 10 bifurcate laterally along the side wall of the column body. The second branch channel 8 extends obliquely upward from the turning point of the second confluence channel 6 to the front side wall of the feeding part 2 and then extends obliquely upward to the left along the arc-shaped side wall of the feeding part. The fourth branch channel 10 extends obliquely upward from the turning point of the second confluence channel 6 to the rear side wall of the feeding part 2 and then extends obliquely upward to the right along the arc-shaped side wall of the feeding part. The second branch channel 8 and the fourth branch channel 10 form a certain angle.
[0035] As Figure 2 shown, both the first branch channel 7 and the second branch channel 8 extend to the front side wall of the feeding part 2, where they intersect and communicate with each other on the front side wall and form a certain angle. Similarly, both the third branch channel 9 and the fourth branch channel 10 extend to the rear side wall of the feeding part 2, where they intersect and communicate with each other on the rear side wall and form a certain angle.
[0036] In some embodiments, the first branch channel 7 and the second branch channel 8, and the third branch channel 9 and the fourth branch channel 10 all intersect at the central axis of the feeding part 2. The angle formed by the intersection of the first branch channel 7 and the second branch channel 8 is opposite to the upper and lower positions of the feeding port 1, and both are located at the central axis of the column body.
[0037] The above technical solution finally realizes that the first confluence channel 5, the second confluence channel 6, and the first branch channel 7, the second branch channel 8, the third branch channel 9, and the fourth branch channel 10 are all interconnected, which can ensure the uniform flow of the insulating material between multiple channels, making the flow path of the outer layer color layer insulating material longer and squeezing it onto the conductor later than the inner layer color insulating material.
[0038] In this embodiment, as Figure 3 、 Figure 4 shown, a positioning device 11 is also fixedly provided on the side of the feeding part 2 close to the first confluence channel 5 for fitting into the corresponding groove inside the machine head to prevent the diverter from rotating inside the machine head. A limiting device 12 is sleeved below the positioning device 11 and at a certain position from the bottom of the feeding part 2 to limit the diverter, so that when the diverter is used in the machine head, there is a certain distance between both sides and the inner wall of the machine head, leaving a certain space for the color layer insulating material.
[0039] In this embodiment, as Figure 5As shown, during use, the diverter is disposed laterally in the head. The die core channel 4 is a die core member with one end tapered and the other end cylindrical. A channel for the conductor to pass through is provided at the inner central axis thereof. The die core channel 4 is embedded in a tapered groove formed inside the cylinder. The cylindrical end is close to the edge of the cylinder, and the tapered end faces inwardly embedded in the cylinder. The tapered groove has openings at both ends. The small opening end of the tapered groove is tightly fixed with a die sleeve channel 14. The die sleeve channel 14 has openings at both ends. The end thereof away from the die core channel 4 is tightly fixed with a cover plate 13. The cover plate 13 is tightly fitted with the inner wall of the cylinder.
[0040] The tapered end of the die core channel 4 penetrates into the die sleeve channel 14. The die sleeve channel 14 is hollow inside and allows the insulating material to flow in. The cover plate 13 is provided with a perforation for the conductor to pass through. The position of the perforation is opposite to the channel opening at the tapered end of the die core channel 4, facilitating the smooth outflow of the conductor from the diverter and preventing the conductor from being blocked and affecting the working efficiency.
[0041] The conductor penetrates from the cylindrical end of the die core channel 4 and exits from its tapered end into the die sleeve channel 14. Color insulating material is coated in the die sleeve channel 14. There is a certain distance between the outer side of the die core channel 4 and the inner wall of the tapered groove. The inner layer color insulating material and the outer layer color insulating material flow into the die sleeve channel 14 on both sides of the die core channel 4 to cover the conductor with pigment. The cover plate 13 is provided with a perforation for the conductor to pass through, which is used to prevent the insulating material from overflowing from the diverter.
[0042] In some embodiments, both the cover plate 13 and the die sleeve channel 14 are cylindrical structures. The diameter of the die sleeve channel 14 is smaller than the diameter of the cover plate 13, facilitating the complete covering of the die sleeve channel 14 by the cover plate and preventing the insulating material from overflowing.
[0043] It should be noted that although the outer layer color insulating material will form another color layer on the conductor with the existing inner layer color layer when extruded, achieving the purpose of simultaneously extruding a double-color layer, it does not form two insulating layers, but a single insulating layer with two color layers. That is, the inner layer color insulating material and the outer layer color insulating material use the same insulating material. The two are injected simultaneously. Since the flow path of the outer layer color insulating material is longer, it will cover the conductor later than the inner layer color insulating material. Therefore, when the outer layer color insulating material is extruded, it will be on the conductor with the existing inner layer color layer. At this time, the inner layer color insulating material has not yet solidified, and the inner layer color insulating material will fuse with the outer layer color insulating material and form a single insulating layer after solidification. The two color layers cannot be separated.
[0044] Detailed description of the working principle:
[0045] The head is a component of the extruder. The extruder also includes a diverter. The conductor passes through the diverter, and color insulating material is injected from the head into the diverter to coat the color insulating material around the conductor to form an insulating layer.
[0046] When in use, the single-layer double-color insulation extruder is placed on its side. The conductor penetrates into the cylindrical end of the die core channel 4 and exits from its tapered end into the die sleeve channel 14. The inner-layer color insulating material is injected through the main machine head from one end of the tapered groove close to the edge of the cylinder. It will be extruded into the gap between the tapered groove and the die core channel 4, flow into the die sleeve channel 14 and be directly extruded onto the surface of the conductor. The outer-layer color insulating material is injected through the auxiliary machine head from the feeder port 1 of the diverter. It is extruded to both sides at the feeder port 1, and successively passes through the first confluence channel 5, the second confluence channel 6, and the first, second, third, and fourth branch channels until it overflows from each branch channel and completely covers the covering part 3 of the diverter, and spreads into the interior of the tapered groove. It floods in from the large opening end of the tapered groove and is extruded in the gap between the tapered groove and the die core channel 4, and flows into the die sleeve channel 14 through the small opening end of the tapered groove. Since the outer-layer color insulating material needs to flow through each confluence channel and each branch channel, and the path is long, the time for it to flow into the die sleeve channel 14 is later than that of the inner-layer color insulating material. Therefore, when the outer-layer color insulating material is extruded, another color layer will be formed on the conductor with the existing inner-layer color layer, achieving the purpose of simultaneously extruding double-color layers.
[0047] Specifically, the outer-layer color insulating material enters from the feeder port 1 of the diverter and flows along the first confluence channel 5 and the second confluence channel 6. Until after the bifurcation of the first and second confluence channels 6, it continues to flow along the first branch channel 7, the second branch channel 8, the third branch channel 9, and the fourth branch channel 10 until all the branch channel openings are filled. The outer-layer color insulating material overflows from each branch channel opening to cover the covering part 3 of the diverter, forming another color layer, and is extruded onto the inner-layer color layer (as Figure 2 the inner arrow indicates the flow direction of the inner-layer color layer, and the outer arrow indicates the flow direction of the outer-layer color layer), achieving the purpose of simultaneously extruding double-color layers.
[0048] Although the specific implementation manners of the present invention are described above in conjunction with the accompanying drawings, it is not a limitation to the protection scope of the present invention. Those skilled in the art should understand that based on the technical solutions of the present invention, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the present invention.
