Description

Technical Field

[0001] The utility model belongs to the field of cable processing, and more specifically relates to a segmented temperature-raising type cable processing device. Background Art

[0002] Cables are typically made of one or more mutually insulated conductors and an outer insulating layer. They transmit electricity or information from one location to another, characterized by internal conduction and external insulation. Cables are often placed at high altitudes or buried deep underground, where they are constantly exposed to environmental erosion, placing significant strain on the outer insulation layer. Currently, the most commonly used cable insulation layer is rubber. After the rubber is coated on the intermediate conductor, it is further vulcanized in a vulcanization pipe to ensure the rubber has high elasticity, heat resistance, and tensile strength.

[0003] However, vulcanized rubber has low surface strength and poor corrosion resistance, making it susceptible to damage and corrosion in service environments. Therefore, it is necessary to improve the corresponding surface mechanical strength and corrosion resistance. Existing cable sheathing devices generally use rubber raw materials for direct coating. The cable sheathing formed by such coating devices has poor performance and cannot guarantee long-term and intact use in service.

[0004] For example, the patent document disclosed in the Chinese patent application number: CN202210891503.7 and the publication date: November 8, 2022, discloses a cable core covering molding device for cable processing, including a covering body, a feeding barrel is provided on the upper side of the covering body, a rubber extruder is provided on the front side of the covering body, an extrusion mechanism is provided on the right side of the rubber extruder, and a cable core is provided in the rubber extruder; a cooling box is provided on the right side of the rubber extruder.

[0005] Another example is a Chinese patent application with the number CN202310396169.2, published on June 30, 2023, which discloses a cable core overmolding device for cable processing, relating to the field of cable processing technology. The cable core overmolding device comprises a processing box, a cleaning unit, a processing unit, and a cooling unit. The cleaning unit is provided on the processing box and includes a cleaning drum and a cleaning brush. The cleaning brush is fixedly mounted on the inner wall of the cleaning drum.

[0006] In both of the above solutions, rubber is used to cover the cable, which has the aforementioned problem that the performance of the cable covering layer is poor and it is difficult to ensure long-term good use in service. Summary of the Invention

[0007] 1. Problems to be solved

[0008] In view of the poor performance of the cable coating layer formed by the existing cable coating device, which is difficult to ensure long-term perfect use in service, the utility model provides a segmented heating type cable processing equipment, which divides the cable insulation layer coating into multiple sections for processing, forms the insulation layer containing multiple oxide powders under different processing environments, and effectively improves the surface performance of the cable.

Therefore, the scope of the present invention is limited only by the appended claims.

[0030] Example 1

[0031] A segmented heating type cable processing equipment is used to form an insulating layer on the cable surface during the cable processing process. Its specific structure and technical effects are described in detail below.

[0032] like Figure 1 As shown, the processing equipment includes a cable conveying conduit 1 with a fixed bracket 7 installed at the bottom. The cable conveying conduit 1 includes a cable inlet and a cable outlet. A rubber conveying device 2 is installed on the cable conveying conduit 1 near the cable inlet. The cable conveying conduit 1 includes a first processing section 11, a second processing section 12, and a third processing section 13. The first processing section 11, the second processing section 12, and the third processing section 13 are respectively equipped with a steam conveying device 3 and a powder conveying device 4.

[0033] Under the above structure, the cable conveying pipeline 1 is divided into three processing sections, and different oxide powders are conveyed in each processing section and a steam heating environment of different temperatures is provided, so that the cable will undergo a segmented heating process when passing through the conveying pipeline, thereby combining insulation layers with different functions with the cable in turn, effectively improving the surface performance of the cable.

[0034] In addition, a heating device 5 and a temperature detection device are installed on the pipelines of the first processing section 11, the second processing section 12, and the third processing section 13. The heating device 5 can maintain the temperature of each processing section within a set range, while the temperature detection device allows workers to accurately monitor the real-time temperature of each processing section, facilitating real-time temperature control through the heating device according to production conditions.

[0035] Furthermore, the rubber conveying device 2 and the powder conveying device 4 on the pipelines of the first processing section 11, the second processing section 12, and the third processing section 13 are equipped with agitators to agitate the material, preventing it from compacting and ensuring smooth material transportation. The pipelines of the second processing section 12 and the third processing section 13 are each equipped with a humidity detection device 6, which can monitor the humidity of the processing section in real time and thus control the steam input.

[0036] The processing is divided into the following steps.

[0037] Step 1: Add unsoftened rubber to the rubber conveying device 2, and add oxide powder 1# (iron oxide) with a content of about 1-2wt% from the powder conveying device 4 of the first processing section 11 to the cable processing equipment, and heat the first processing section 11 to 120°C through the steam conveying device 3 of the first processing section 11. The insulation process lasts for 15 minutes for the initial softening of the rubber and its mixing with the iron oxide to improve the surface hardness of the cable.

[0038] Step 2: Then, oxide powder 2# (silicon dioxide) is continuously added through the powder conveying device 4 of the second processing section 12, and the second processing section 12 is heated to 150°C through the steam conveying device 3 of the second processing section 12. The heat preservation process lasts for 15 minutes to continue softening the rubber and mixing it with silicon dioxide, thereby improving the corrosion resistance of the cable.

[0039] Step 3: Then, the powder conveying device 4 of the third processing section 13 continues to add oxide powder 3# (titanium dioxide), and the third processing section 13 is heated to 180°C through the steam conveying device 3 of the third processing section 13. The insulation process lasts for 15 minutes to continue softening the rubber and mixing it with titanium dioxide, thereby improving the tensile strength and corrosion resistance of the cable.

[0040] Step 4: When the humidity in the processing section detected by the humidity detection device 6 exceeds 75%, the steam delivery device 3 will be temporarily closed until the humidity is lower than 40% and then opened.

[0041] Step 5: After the cable leaves the processing equipment, the rubber and different oxides will be evenly coated on the cable, resulting in a corrosion-resistant cable with high mechanical strength.

[0042] In summary, the segmented heating cable processing equipment of this embodiment divides the insulation layer covering of the cable into multiple segments for processing, and forms an insulation layer containing a variety of oxide powders under different processing environments, thereby effectively improving the surface performance of the cable.
