Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, and in particular to a high-temperature resistant jumper cable production equipment and process. Background Technology

[0002] Cable manufacturing refers to the process of assembling conductors, insulation materials, sheathing materials, and other accessories into various types of cables. A cable is a conductor assembly used to transmit power, signals, or data, and is widely used in power transmission, communications, electronic equipment, and industrial manufacturing.

[0003] However, traditional technology has some problems: when traditional equipment extrudes and manufactures the outer insulation tube of a cable, its inner wall is usually designed to be circular. In order to provide heat insulation protection for the internal wires, a tubular heat insulation component is usually placed between the wires and the insulation tube. However, during cable transportation and use, the heat insulation component may rotate or become entangled inside the insulation tube, which can easily cause the heat insulation component to deform, thereby squeezing the wires and damaging them. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in cables produced by existing technology, the heat insulation component may rotate or become entangled inside the insulating tube during transportation and use, which can easily lead to deformation of the heat insulation component and thus squeeze the wire. Therefore, this invention proposes a high-temperature resistant jumper cable production equipment and process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-temperature resistant jumper cable production equipment includes a cabinet, an extrusion assembly fixedly installed on the upper part of the cabinet, a feeding assembly fixedly installed at the input end of the extrusion assembly, and a forming tube fixedly connected to the output end of the extrusion assembly. The forming tube has an irregularly shaped cavity inside, and the forming tube receives the material transmitted by the extrusion assembly to form an insulating tube. The inner wall of the insulating tube has an integrally formed guide channel.

[0007] To form the irregular cavity, a heat insulation tube can be installed inside the insulating tube. The heat insulation tube has protrusions on its outside that match the recesses of the forming column, and a support ring is provided inside. During cable manufacturing, the wire is placed inside the heat insulation tube to effectively insulate the wire. The heat insulation tube will not be misaligned or twisted. Preferably, the forming tube includes an outer tube, and a forming column is fixedly installed inside the outer tube. Several recesses are evenly arrayed on the outer circumference of the forming column. The outer tube cooperates with the forming column to form the irregular cavity.

[0008] To facilitate the molding of insulating tubes of different thicknesses, users can achieve this by replacing molding columns of different diameters. Furthermore, the outer tube is fixed to the upper part of the cabinet, and a support frame is fixedly installed inside the outer tube on the side near the extrusion assembly. The molding column is screwed to one side of the support frame.

[0009] To enable material feeding to the extrusion assembly, the extrusion assembly includes a transfer seat, an extrusion auger is rotatably mounted inside the transfer seat, the outer tube is connected and communicates with the transfer seat, and a feed pipe is fixedly connected to the upper part of the transfer seat.

[0010] To enable the extrusion and transport of raw materials, an extrusion motor is fixedly installed on one side of the upper part of the cabinet, and the output end of the extrusion motor is fixedly connected to one end of the extrusion auger.

[0011] To achieve preheating and stirring of raw materials and prevent them from cooling and solidifying during transport, the feeding assembly includes a processing tube fixed to the upper part of the feeding tube. The processing tube has a through hole for receiving raw materials on its exterior. A stirring motor is fixedly installed on the upper part of the processing tube, and a stirring paddle is fixedly connected to the output end of the stirring motor. The stirring paddle is located inside the processing tube, and an electric heating tube for heating is fixedly installed on the exterior of the processing tube.

[0012] To prevent some raw materials from cooling and clumping, they are filtered through a filter element, the main body of which is conical. The filtered raw materials are transported to the upper part of the processing tube for secondary heating via an ascending auger. Furthermore, the processing tube is provided with an ascending channel on the outside, the upper and lower parts of which are respectively connected to the central cavity of the processing tube. A round-headed ascending auger is rotatably installed inside the ascending channel of the processing tube, and the filter element is fixedly installed at the bottom of the processing tube.

[0013] To achieve the combined drive of multiple ascending augers, and to hydraulically drive the filter head to move downwards and contact the insert plate when the filter head is clogged, thereby clearing the blockage, the ascending augers are further provided in multiple units. Each ascending auger has a single-layer impeller fixedly connected to its upper part through the transmission pipe. The drive shaft of the stirring motor also has a multi-layer impeller fixedly installed outside. The multi-layer impellers are connected to the single-layer impellers via a transmission belt. The filter element includes a filter head, which is slidably mounted on the lower part of the transmission pipe by a spring. The upper part of the filter head has a filter groove. A top plate is fixedly connected to the bottom of the transmission pipe, and the top plate is movably inserted into the filter groove.

[0014] To facilitate the guiding and transport of the formed insulating tube and to ensure rapid cooling before it enters the guide tube, thus preventing deformation due to incomplete cooling, a guide tube is further fixedly installed on the upper part of the cabinet. The guide tube is located on the side of the forming tube away from the extrusion assembly. The forming tube is screwed to the guide tube via a cooling spiral tube. The cooling spiral tube includes a transfer ring, which is slidably installed outside the forming tube and screwed to the outside of one side of the guide tube. A one-way transfer channel is provided inside the transfer ring. An inlet pipe and an outlet pipe are fixedly connected to one side of the transfer ring, and the transfer ring and the one-way transfer channel are respectively connected to the inlet pipe and the outlet pipe.

[0015] A manufacturing process for high-temperature resistant jumper cables includes the following steps:

[0016] Step 1: Transfer the raw materials to the feeding assembly;

[0017] Step 2: Start the extrusion motor to drive the extrusion assembly to extrude the raw material;

[0018] Step 3: The forming tube accepts the raw material from the extrusion assembly and produces an insulating tube with internal limiting grooves, which, together with wires and heat insulation components, completes the cable production.

[0019] Compared with the prior art, the present invention provides a high-temperature resistant jumper cable production equipment and process, which has the following beneficial effects:

[0020] 1. The high-temperature resistant jumper cable production equipment and its process, firstly, through the irregular cavity design inside the forming tube, the molten material directly generates the inner wall guide channel during extrusion molding. This guide channel closely matches the external protrusion of the heat insulation tube, fundamentally avoiding the phenomenon of the heat insulation tube rotating, misaligning, or entangled inside the insulation tube. At the same time, it reduces the risk of the heat insulation tube causing compression or damage to the wire due to movement or deformation. Secondly, the support ring inside the heat insulation tube further improves the stability of the internal wire. Even in complex transportation or usage scenarios, the wire can still maintain good heat insulation and protection, effectively extending the service life of the cable. In addition, the integrated molding process reduces additional processing steps, allowing the insulation tube and guide channel to be completed in one go, reducing errors in the production process, while improving production efficiency and quality consistency. This optimized design not only solves the problems in traditional processes, but also simplifies the production process while ensuring cable performance, providing reliable technical support for the manufacture of high-performance cables.

[0021] The parts not mentioned in this device are the same as or can be implemented using existing technology. This invention effectively prevents the heat insulation tube from rotating or misaligning inside the insulation tube by precisely matching the irregular cavity with the guide channel. At the same time, the support ring inside the heat insulation tube stabilizes the wire and avoids squeezing and damage. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0039] Example:

[0040] Reference Figure 1 - Figure 9 A high-temperature resistant jumper cable production equipment includes a cabinet 1, an extrusion assembly 3 is fixedly installed on the upper part of the cabinet 1, a feeding assembly 4 is fixedly installed at the input end of the extrusion assembly 3, and a forming tube 6 is fixedly connected to the output end of the extrusion assembly 3. The forming tube 6 has an irregular cavity inside, and the forming tube 6 receives the material transmitted by the extrusion assembly 3 and forms an insulating tube. The inner wall of the insulating tube has an integrally formed guide channel.

[0041] The aforementioned high-temperature resistant jumper cable production equipment stably transports the pre-processed raw materials to the extrusion assembly 3 via the feeding assembly 4. After receiving the raw materials from the feeding assembly 4, the extrusion assembly 3 gradually pushes the raw materials to the forming tube 6 through its internal extrusion auger 303. After the molten material enters the forming tube 6, the irregular cavity inside the forming tube 6 shapes the molten material into an insulating tube with a specific inner and outer wall structure according to the design shape. During the forming process, the inner wall of the insulating tube directly generates a guide channel through an integrated molding process, providing precise positioning for the subsequent installation of the heat insulation tube 8.

[0042] The irregular cavity design allows the external protrusion of the heat insulation tube 8 to match the guide channel on the inner wall of the insulation tube. This precise fit prevents the heat insulation tube 8 from rotating or misaligning inside the insulation tube. In addition, the support ring 9 inside the heat insulation tube 8 provides stable support, ensuring that the wires placed inside the heat insulation tube 8 are not squeezed or damaged during transmission. Through the above process, the equipment effectively solves the problem of wire damage caused by the easy misalignment of the heat insulation tube 8 in traditional cable structures.

[0043] To form an irregular cavity, a heat insulation tube 8 can be installed inside the insulating tube. The heat insulation tube 8 has a protrusion on its outside that matches the recess 604 of the forming column 603, and a support ring 9 is provided inside. During cable manufacturing, the wire is placed inside the heat insulation tube 8 to effectively insulate the wire. The heat insulation tube 8 will not be misaligned or twisted. Preferably, the forming tube 6 includes an outer tube 601, and a forming column 603 is fixedly installed inside the outer tube 601. A plurality of recesses 604 are evenly arrayed on the outer circumference of the forming column 603. The outer tube 601 cooperates with the forming column 603 to form an irregular cavity.

[0044] The forming tube 6 consists of an outer tube 601 and a forming column 603. The outer tube 601 provides constraints on the external shape to ensure that the shape of the insulating tube conforms to the standard. The forming column 603 is responsible for forming the inner wall of the insulating tube. The evenly distributed depressions 604 on its surface determine the specific structure of the irregular cavity, so that the inner wall of the insulating tube has a stable guiding channel.

[0045] To facilitate the molding of insulating tubes of different thicknesses, users can replace molding columns 603 of different diameters. Furthermore, the outer tube 601 is fixed to the upper part of the cabinet 1, and a support frame 602 is fixedly installed inside the outer tube 601 near the extrusion assembly 3. A molding column 603 is screwed to one side of the support frame 602. To feed material to the extrusion assembly 3, the extrusion assembly 3 includes a transmission seat 301, inside which an extrusion auger 303 is rotatably mounted. The outer tube 601 is connected and communicates with the transmission seat 301, and a feed pipe 302 is fixedly connected to the upper part of the transmission seat 301. To achieve the extrusion and transmission of raw materials, an extrusion motor 2 is fixedly installed on one side of the upper part of the cabinet 1, and the output end of the extrusion motor 2 is fixedly connected to one end of the extrusion auger 303.

[0046] The support frame 602 is fixedly installed inside the outer tube 601, on the side close to the extrusion assembly 3. The support frame 602 is fixed to the forming column 603 by screw connection. The forming column 603 is designed as a modular structure. By replacing the forming column 603 with different diameters, the size of the irregular cavity can be adjusted, thereby controlling the wall thickness of the insulating tube. This function improves the flexibility of the equipment and makes it adaptable to the production needs of different specifications.

[0047] The extrusion auger 303 inside the transmission seat 301 is driven by the extrusion motor 2, which gradually pushes the raw material supplied through the feed pipe 302. The extrusion motor 2 is fixed on the upper part of the cabinet 1, and its output end is directly connected to one end of the extrusion auger 303 to provide power for the rotation of the auger. By adjusting the speed of the extrusion motor 2, the running speed of the extrusion auger 303 can be precisely controlled, thereby affecting the transmission speed and plasticizing effect of the raw material and adapting to different production needs.

[0048] The transfer seat 301 and the outer tube 601 are connected by a sealing design, which ensures that the molten material can be smoothly transported from the transfer seat 301 to the forming tube 6. The sealing design also effectively prevents material leakage and improves the cleanliness and production efficiency of the equipment.

[0049] To achieve preheating and stirring of the raw materials and prevent them from cooling and solidifying during transport, the feeding assembly 4 includes a processing tube 401, which is fixed to the upper part of the feeding tube 302. The processing tube 401 has a through hole for receiving raw materials on its exterior. A stirring motor 403 is fixedly installed on the upper part of the processing tube 401, and a stirring paddle 408 is fixedly connected to the output end of the stirring motor 403. The stirring paddle 408 is located inside the processing tube 401, and an electric heating tube 402 for heating is fixedly installed on the exterior of the processing tube 401.

[0050] The processing tube 401 receives raw materials through an external through-hole. These materials are conveyed by the feeding assembly 4. An electric heating element 402 is installed on the outside of the processing tube 401 to provide a constant temperature environment for the raw materials, preventing them from cooling and solidifying during transport. A stirring motor 403 is fixed to the upper part of the processing tube 401, and its output end is connected to a stirring paddle 408. The stirring paddle 408 rotates inside the processing tube 401, thoroughly stirring the raw materials to ensure uniform heating and prevent clumping caused by localized overheating or uneven heating. This also improves the flowability and mixing quality of the raw materials. The stirred and heated raw materials flow directly into the feeding pipe 302 through the bottom of the processing tube 401.

[0051] To prevent some raw materials from cooling and clumping, they are filtered through a filter element 409, which has a conical shape. The filtered raw materials are transported to the upper part of the processing tube 401 for secondary heating via an ascending auger 407. Furthermore, the processing tube 401 has an ascending channel on its exterior. The upper and lower parts of the ascending channel of the processing tube 401 are respectively connected to the central cavity of the processing tube 401. A round-headed ascending auger 407 is rotatably installed inside the ascending channel of the processing tube 401, and the filter element 409 is fixedly installed at the bottom of the processing tube 401. To achieve the combined drive of multiple ascending augers 407, and to hydraulically drive the filter head 4092 to move down and contact the insert plate when the filter head 4092 is clogged, thereby completing the unblocking, multiple ascending augers 407 are provided. Each ascending auger 407 has a single-layer rotating wheel 406 fixedly connected to its upper part through the transmission pipe. A multi-layer rotating wheel 404 is also fixedly installed on the outside of the drive shaft of the stirring motor 403. The multi-layer rotating wheel 404 is connected to the single-layer rotating wheel 406 through the transmission belt 405. The filter element 409 includes a filter head 4092. The filter head 4092 is slidably installed on the lower part of the transmission pipe through the spring 4091. A filter groove 4093 is opened on the upper part of the filter head 4092. A top plate 4094 is fixedly connected to the bottom of the transmission pipe. The top plate 4094 is movably inserted into the filter groove 4093.

[0052] To prevent raw materials from clumping due to cooling during transport, the equipment is equipped with a filter element 409 for pretreatment. The main body of the filter element 409 is conical, which can effectively separate larger particles of clumped raw materials, ensuring smooth transport. The filter element 409 is located at the bottom of the processing pipe 401. When the raw materials pass through the filter element 409, they are first screened by the filter tank 4093. The size of the filter tank 4093 can limit the maximum diameter of the raw material particles, thereby removing materials that do not meet the requirements. At the same time, the filter head 4092 is slidably installed at the bottom of the transport pipe by a spring 4091, and its position can be adjusted when necessary. When the filter head 4092 becomes clogged, hydraulic pressure moves the filter head 4092 downward, so that it contacts the insert plate and generates pressure, thereby clearing the blockage. This design reduces the risk of clogging while ensuring the efficient operation of the filtration system.

[0053] The filtered raw material is transported from the bottom to the upper part of the processing tube 401 by the rising auger 407. The rising auger 407 has a round head design, and its rotation can stably transport the material along the rising channel and prevent the raw material from overheating or wearing due to friction during the transport process. The processing tube 401 is designed with a rising channel on the outside. The upper and lower parts of the rising channel are connected to the central cavity of the processing tube 401. After filtration, the raw material enters the rising channel from the lower part of the channel and is gradually lifted to the upper part of the processing tube 401 by the rising auger 407. Multiple rising augers 407 are jointly driven by single-layer rotating wheels 406. The upper part of each rising auger 407 is connected and fixed to the transmission tube. The transmission process is stable and efficient. In addition, a multi-layer rotating wheel 404 is installed on the outside of the drive shaft of the stirring motor 403 and connected to the single-layer rotating wheel 406 through the transmission belt 405, thereby realizing the synchronous drive of multiple rising augers 407. The overall design ensures that the raw material is always in a good processing state during the transmission and filtration process, providing a high-quality material supply for subsequent processing.

[0054] To achieve the guiding and transmission of the formed insulating tube and to facilitate rapid cooling before it enters the guide tube 5, thus preventing deformation of the insulating tube due to incomplete cooling, a guide tube 5 is further fixedly installed on the upper part of the cabinet 1. The guide tube 5 is located on the side of the forming tube 6 away from the extrusion assembly 3. The forming tube 6 is screwed to the guide tube 5 through a cooling spiral tube 7. The cooling spiral tube 7 includes a transmission ring 701, which is slidably installed on the outside of the forming tube 6. The transmission ring 701 is screwed to the outside of one side of the guide tube 5. A one-way transmission channel 704 is opened inside the transmission ring 701. A water inlet pipe 702 and a water outlet pipe 703 are fixedly connected to one side of the transmission ring 701. The transmission ring 701 and the one-way transmission channel 704 are respectively connected to the water inlet pipe 702 and the water outlet pipe 703.

[0055] To ensure stable transport of the formed insulating tube and rapid cooling before it enters the guide tube 5, a guide tube 5 is installed on the side of the forming tube 6 away from the extrusion assembly 3. The forming tube 6 is connected to the guide tube 5 via a cooling spiral tube 7. The cooling spiral tube 7 employs a transfer ring 701 structure, which is slidably mounted on the outside of the forming tube 6 and threadedly connected to the outside of the guide tube 5. A unidirectional transport channel 704 is designed inside the transfer ring 701 to guide the flow of the cooling medium and ensure cooling efficiency. An inlet pipe 702 and an outlet pipe 704 are fixedly connected to one side of the transfer ring 701. Water pipe 703 and water inlet pipe 702 are used to introduce cooling medium, and water outlet pipe 703 is used to discharge heated medium, forming a continuous circulating cooling system. After the insulating tube of the forming tube 6 is formed, it is quickly guided to the cooling area under the action of the transfer ring 701. During the sliding process, the transfer ring 701 of the cooling spiral tube 7 distributes the cooling medium evenly on the outer surface of the insulating tube through the unidirectional transfer channel 704, ensuring that the temperature of the insulating tube drops rapidly and maintains a uniform cooling effect. This process effectively avoids inconsistent shrinkage inside and outside the insulating tube due to insufficient cooling, thereby preventing product deformation.

[0056] The guide tube 5 is fixedly installed on the upper part of the cabinet 1. Its function is to provide a stable transmission path for the cooled insulating tube and prevent the insulating tube in the forming tube 6 from bending or deforming due to incomplete cooling. After the cooled insulating tube flows out from the transmission ring 701, it continues to be transmitted along the channel of the guide tube 5, thus achieving efficient connection of the entire cooling and transmission process. Through this design, the equipment can ensure that the formed insulating tube maintains its structural integrity during the cooling and transportation process, laying a stable foundation for subsequent operations.

[0057] A manufacturing process for high-temperature resistant jumper cables includes the following steps:

[0058] Step 1: Transfer the raw materials to the feeding assembly 4;

[0059] Step 2: Start the extrusion motor 2 to drive the extrusion assembly 3 to extrude the raw material;

[0060] Step 3: The forming tube 6 accepts the raw material from the extrusion component 3 and produces an insulating tube with a limiting groove inside, which is then used in conjunction with wires and heat insulation components to complete cable production.

[0061] In this invention, the pre-processed raw material is stably conveyed to the extrusion assembly 3 by the feeding component 4. After receiving the raw material from the feeding component 4, the extrusion assembly 3 gradually pushes the raw material to the forming tube 6 through the extrusion auger 303 inside. After the molten material enters the forming tube 6, the irregular cavity inside the forming tube 6 shapes the molten material into an insulating tube with a specific inner and outer wall structure according to the design shape. During the forming process, the inner wall of the insulating tube directly generates a guide channel through an integral forming process, providing precise positioning for the subsequent installation of the heat insulation tube 8. The design of the irregular cavity allows the external protrusion of the heat insulation tube 8 to match the guide channel of the inner wall of the insulating tube. This precise fit prevents the heat insulation tube 8 from rotating or misaligning inside the insulating tube. In addition, the support ring 9 inside the heat insulation tube 8 provides stable support, ensuring that the wire placed inside the heat insulation tube 8 is not squeezed or damaged during transmission. Through the above process, the equipment effectively solves the problem of wire damage caused by the easy misalignment of the heat insulation tube 8 in traditional cable structures.

[0062] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
