Description

Technical Field

[0001] This utility model relates to the technical field of coaxial cable production, and in particular to a coaxial cable production extrusion conveying device. Background Technology

[0002] An extruder, also known as a wire and cable extruder, is a type of equipment primarily used for extruding the core wires of various electrical wires and cables, including power cords, power cables, coaxial cables, communication cables, various high-temperature silicone cables, Teflon cables, coaxial cables, network cables, optical fibers, and drop cables. Extruders are an important category of plastics machinery. Their die head design, based on the angle between the material flow direction and the screw centerline, can be further subdivided into types such as right-angle die heads and angled die heads. The working principle of a screw extruder is to utilize the pressure and shear force generated by the rotating screw to ensure that the material is fully plasticized and uniformly mixed, ultimately forming the final product through the die. Extruders are indispensable equipment in the extrusion insulation process for wires and cables.

[0003] In the production of coaxial cables, customers often require cables of the same specification to have different insulation colors, meaning each color needs to be extruded as a separate wire. However, in practice, changing insulation colors often requires a certain time interval, causing the equipment to be unable to maintain continuous extrusion. If another color is added directly, although continuous production can be achieved, the two colors will mix, resulting in a section of finished cable that does not meet the color requirements, thus wasting materials. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a coaxial production extruder conveying device, in which two coloring components can be independently responsible for the connection between the two first tubes and the coloring of the material, thereby realizing continuous production, making efficient use of materials, and significantly reducing waste caused by unqualified color.

[0006] To achieve the above objectives, this utility model proposes a coaxial production extrusion conveying device, including a conveying pipe assembly and two coloring components. The conveying pipe assembly includes a connector and two first pipe bodies respectively disposed at both ends of the connector. A first rotating shaft is disposed through the interior of the connector, with each end of the first rotating shaft passing through one of the two first pipe bodies. A first driving mechanism is provided at one end of the first rotating shaft, and first augers are respectively provided on both sides of the first rotating shaft. The two first augers are located within their respective first pipe bodies. Each first pipe body has two notches near the end face of the connector, and the two first augers... A tube body is provided with an inlet and an outlet, and a valve body is provided inside the notch; two coloring components are respectively arranged on both sides of the connector, and each coloring component includes a second tube body and two connecting joints respectively provided at both ends of the second tube body, wherein the two connecting joints are respectively connected to the corresponding notch; a second rotating shaft is provided inside the second tube body, a second spiral auger is provided on the outside of the second rotating shaft, and a pigment chamber is provided inside the second rotating shaft. A spray hole is provided on one side of the pigment chamber. One end of the second rotating shaft passes through the second tube body and is provided with a second driving mechanism, and the other end of the pigment chamber extends out of the second tube body and is connected to an inlet pipe.

[0007] This invention relates to a coaxial production extruder conveyor device, in which two coloring components can independently handle the connection between the two first tubes and the coloring of the material. This design not only supports a continuous and uninterrupted production process but also ensures that the material is accurately colored as it passes through the coloring components. Most importantly, the two coloring components do not interfere with each other, effectively avoiding the risk of color mixing, thus enabling efficient material utilization and significantly reducing waste caused by substandard coloring.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown 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 this utility model, and should not be construed as limiting this utility model.

[0021] The coaxial production extruder conveying device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0022] like Figures 1-3 As shown, the coaxial production extruder conveying device of this utility model embodiment may include a conveying pipe assembly 10 and a coloring assembly 50.

[0023] The conveying pipe assembly 10 may include a connector 101 and two first pipe bodies 102 respectively located at both ends of the connector 101. A first rotating shaft 21 is disposed inside the connector 101, with each end of the first rotating shaft 21 passing through one of the two first pipe bodies 102. A first driving mechanism 30 is provided at one end of the first rotating shaft 21, and first spiral augers 211 are respectively provided on both sides of the first rotating shaft 21, with each spiral auger 211 located within its corresponding first pipe body 102. Each first pipe body 102 has two notches 1021 near the end face of the connector 101, and each of the two first pipe bodies 102 has an inlet and an outlet. A valve body 40 is disposed within each notch 1021. Two valve bodies 40 are provided, and both valve bodies 40 and the inlet are located on the same first pipe body 102. It is understood that the valve body 40 has the ability to precisely control the connection state of its corresponding notch 1021, allowing personnel to flexibly perform closing or opening operations on the corresponding notch 1021 through the valve body 40.

[0024] The first drive mechanism 30 may include a first motor, wherein the output end of the first motor is connected to the first rotating shaft 21 and the first motor is located near the feed inlet. When the first motor is started, it will drive the first rotating shaft 21 to rotate stably, thereby driving the first spiral auger 211 to operate efficiently and realize the material conveying function of the first tube 102.

[0025] It should be noted that the first tube 102 described in this embodiment has a heating function, which can efficiently heat the material introduced from the inlet. This heating process continues as the material passes through the conveying tube assembly 10, ensuring that the material reaches the ideal temperature. Finally, the fully heated material is smoothly discharged from the outlet and directly delivered to the extruder head for subsequent precision wrapping of the coaxial cable insulation layer.

[0026] Two coloring components 50 are respectively disposed on both sides of the connector 101. The coloring component 50 may include a second tube body 51 and two connecting joints 52 respectively disposed at both ends of the second tube body 51. The two connecting joints 52 are respectively connected to the corresponding notches 1021. A second rotating shaft 22 is disposed inside the second tube body 51. A second spiral auger 221 is disposed on the outside of the second rotating shaft 22. A pigment cavity 222 is disposed inside the second rotating shaft 222. A spray hole 223 is disposed on one side of the pigment cavity 222. The spray hole 223 is disposed near the feed inlet. One end of the second rotating shaft 22 passes through the second tube body 51 and is provided with a second driving mechanism 60. The second driving mechanism 60 described in this embodiment can control the second rotating shaft 22 to rotate. The second driving mechanism 60 may include a second motor 61, a linkage wheel 62 and a synchronous belt 63. The linkage wheel 62 is connected to the output end of the second motor 61, and the linkage wheel 62 is connected to the second rotating shaft 22 through the synchronous belt 63. After the second motor 61 is started, it can drive the linkage wheel 62 to rotate. The linkage wheel 62 randomly drives the second rotating shaft 22 to rotate through the synchronous belt 63.

[0027] The other end of the pigment chamber 222 extends out of the second tube 51 and is movably connected to the inlet tube 70. Multiple auxiliary shafts 224 are provided on the outer side of the second rotating shaft 22. These auxiliary shafts 224 are arranged sequentially along the blade direction of the second auger 221. The auxiliary shafts 224 can rotate with the second rotating shaft 22. During rotation, they can deeply mix the material conveyed by the second auger 221, resulting in a more uniform coloring effect within the second tube 51, thereby improving the overall coloring quality and efficiency.

[0028] It should be noted that the inlet tube 70 described in this embodiment can be connected to an external pigment storage device. Through the inlet tube 70, the pigment can be accurately delivered into the pigment chamber 222 and evenly sprayed into the corresponding second tube 51 through the spray hole 223, so as to achieve effective mixing with the material therein.

[0029] It should be noted that the coloring component 50 described in this embodiment cleverly utilizes its corresponding valve body 40 to achieve flexible communication between the two first tubes 102. The two valve bodies 40 described in this embodiment are independently operable. Once one of the valve bodies 40 is activated to open the corresponding notch 1021, the corresponding coloring component 50 can connect with the first tube 102 through this notch 1021, thereby enabling precise coloring of the material during its flow within the coloring component 50.

[0030] If a color change is required, simply close the current valve body 40 and activate the other valve body 40 to establish a connection between the other coloring component 50 and the first tube body 102, achieving precise coloring of different colors. This process ensures the continuity and uninterrupted nature of the production process. Most importantly, the two coloring components 50 do not interfere with each other, effectively avoiding the risk of color mixing, thus enabling efficient material utilization and significantly reducing waste caused by substandard coloring.

[0031] It should be noted that the operation of the coloring component 50 described in this embodiment does not affect the operation of the first rotating shaft 21, thereby enabling precise coloring of the material while ensuring smooth and efficient material transport.

[0032] Specifically, in the actual operation, the relevant personnel first activate a valve body 40 to ensure that the corresponding coloring component 50 is precisely connected and connected with the two first tube bodies 102.

[0033] Subsequently, relevant personnel put the material into the first tube 102 through the inlet. Driven by the first drive mechanism 30, the first rotating shaft 21 begins to rotate, and the first spiral auger 211 inside the first tube 102 then conveys the material through the notch 1021 to the corresponding coloring component 50.

[0034] Inside the coloring assembly 50, the material sequentially passes through the connecting joint 52, the second tube 51, and another connecting joint 52. Inside the second tube 51, personnel skillfully deliver the pigment into the pigment chamber 222 via the inlet pipe 70. The pigment is then evenly sprayed into the second tube 51 through the spray nozzle 223, achieving efficient and precise mixing with the material, thus resulting in a uniform coloring effect. Multiple auxiliary shafts 224 also play an important role in this process, assisting the second auger 221 in further mixing the material to ensure even coloring.

[0035] After the coloring is completed, the material is conveyed through another first tube 102 to the head of the extruder for subsequent precision wrapping of the coaxial cable insulation layer.

[0036] If a color change is required, simply close the current valve body 40 and activate the other valve body 40 to establish a connection between the other coloring component 50 and the first tube body 102, achieving precise coloring of different colors. This process ensures the continuity and uninterrupted nature of the production process. Most importantly, the two coloring components 50 do not interfere with each other, effectively avoiding the risk of color mixing, thus enabling efficient material utilization and significantly reducing waste caused by substandard coloring.

[0037] As one possible scenario, such as when the desired color is a mixture of two colors, two valves 40 can be opened simultaneously, connecting the two coloring components 50 to the two first tubes 102 respectively. The material is then colored along two separate paths and thoroughly mixed in the subsequent first tubes 102, ultimately producing the desired mixed color. This design is not only flexible and versatile but also increases versatility and improves efficiency.

[0038] In summary, the coaxial production extruder conveying device of this utility model embodiment allows two coloring components to independently handle the connection between the two first tubes and the coloring of the material. This design not only supports a continuous and uninterrupted production process but also ensures that the material is accurately colored as it passes through the coloring components. Most importantly, the two coloring components do not interfere with each other, effectively avoiding the risk of color mixing, thus enabling efficient material utilization and significantly reducing waste caused by substandard coloring.
