Description

Technical Field

[0001] This invention relates to the field of enameled wire production technology, and more specifically, to a production apparatus for low-smoke, halogen-free, and environmentally friendly enameled wire. Background Technology

[0002] In existing technologies, the production of low-smoke halogen-free environmentally friendly enameled wire typically involves multiple coating and baking processes. Each coating layer needs to undergo a rapid cooling and shaping process after baking. This process is generally achieved by using air-cooling devices (such as cooling ducts) or water-cooling devices (such as cooling water jackets) to ensure that the coating film can solidify quickly and achieve the required physical properties. In the final forming process, in order to give the enameled wire better flexibility, wear resistance, and facilitate subsequent winding, embedding and other processing operations, the production line will add a lubrication process, that is, apply an extremely thin layer of special lubricant to the surface of the wire through a coating device.

[0003] Currently, the lubrication process commonly involves immersing the enameled wire directly through an oil tank or box filled with lubricating oil. While this contact-based, immersion lubrication method ensures that the wire surface is covered with lubricant, it suffers from inherently low material utilization. This is because the wire only needs a micron-sized lubricating film to adhere to its surface, while the oil tank needs to maintain a much larger volume of oil than actually required to ensure immersion depth. As a result, a large amount of lubricating oil is not effectively coated but remains in the tank, where it is lost due to oxidation, evaporation, leakage by the wire, or periodic replacement. This crude lubrication method not only directly increases the cost of lubricant, a continuous consumable, but also contradicts the environmental and economic characteristics pursued by low-smoke, halogen-free, and environmentally friendly enameled wire. Summary of the Invention

A top ring is threaded on the upper end of the lubrication cavity, and a reducing sleeve is rotatably provided on the lower end of the top ring. A compression spring is provided on the lower end of the reducing sleeve, and the compression spring abuts against the bonding disc.

[0009] Preferably, the pressure plate is provided with a through pipe, and the two sides of the through pipe are respectively connected to the side wall of the pressure plate. The lower end of the through pipe is connected to the oil receiving chamber, and the upper end of the through pipe is connected to the uppermost end of the pressure plate.

[0010] Preferably, the oil collection assembly includes a collection tray that is slidably and sealed within the oil collection chamber, a handle is coaxially disposed within the collection tray, and bottom rings are threaded onto the lower ends of the two oil collection chambers respectively, with a push spring disposed between the collection tray and the bottom rings.

[0011] Preferably, the oil inlet assembly includes an oil pipe threadedly connected to the pressure plate, and the upper end of the through pipe is connected to the lower end of the oil pipe. A control plate and a cracking plate are provided inside the oil pipe. A cone block is fitted inside the control plate, and a pull rod is hinged inside the cone block.

[0014] Preferably, the conveying mechanism includes a motor mounted on a fixed frame, a drive wheel mounted on the drive end of the motor, a belt rotatably mounted on the drive wheel, and the belt pressing on the conveyor belt.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a production apparatus for low-smoke, halogen-free, and environmentally friendly enameled wires, which has the following beneficial effects: This invention fundamentally solves the problem of excessive lubricant waste caused by traditional oil bath immersion lubrication through innovative contact-type precision coating and volume minimization design. Its clamping component uses a rotating pressure plate and conveying blades to actively pump the lubricant confined to the bottom of the lubrication chamber to the narrow gap between the line and the cone, achieving micro-scale and uniform coating only on the surface requiring lubrication. This eliminates the crude method of immersing the entire line in the oil bath. At the same time, the effective volume of the lubrication chamber is dynamically compressed to close to the actual required oil volume through the design of the fitting plate and the volume-reducing sleeve, greatly reducing the total amount of static lubricant remaining in the equipment. This significantly reduces the ineffective occupation and oxidation evaporation loss of lubricant from the source, fundamentally improving the utilization rate of lubricant.

[0016] This invention achieves intelligent dynamic matching between the oil supply rate and the production line speed, ensuring the stability and economy of the lubrication effect. Its oil inlet component cleverly transforms the mechanical rotation driven by the production line traction into a power source for controlling the oil circuit. The centrifugal force generated by the counterweight ball rotating synchronously with the pressure plate drives the axial displacement of the cone block, thereby linearly adjusting the oil outlet gap at the control plate. When the production line speed increases, the rotation speed increases, the centrifugal force increases, and the oil outlet gap automatically increases to increase the oil supply. Conversely, the oil supply is automatically reduced. This pure mechanical closed-loop adjustment structure based on the centrifugal principle is simple and reliable. It can ensure that the oil application amount is always optimally matched with the production cycle without the need for external sensors or control systems, avoiding excessive or insufficient oil supply.

[0017] While pursuing high efficiency and energy saving, this invention fully considers the convenience of equipment operation and the cleanliness of maintenance. Its oil collection component has a variable volume oil storage chamber composed of a collection plate and a push spring set below the lubrication chamber. When it is necessary to replace the line or stop the machine, the lubricating oil in the lubrication chamber can be temporarily transferred to the oil collection chamber by simply pulling down the handle, which effectively prevents leakage and contamination during operation. After the line replacement is completed, the lubricating oil can be easily reset. The clamping component's contact plate provides flexible clamping force through the expansion spring and the compression spring, which can not only stably guide the line but also adapt to the fluctuation of the line diameter within a certain range. Moreover, key components such as the regulating tube and the flow limiting sleeve adopt a replaceable modular design, which facilitates the quick adjustment of process parameters according to product specifications, greatly improving the adaptability and maintenance efficiency of the equipment.

[0018] The structural design of this invention combines excellent versatility and process controllability. By changing the regulating tubes with different inner diameters, the thickness of the oil film coated on the surface of the production line can be precisely controlled to meet the differentiated requirements of different customers or subsequent processing techniques for the lubrication layer. Furthermore, by changing the flow-limiting sleeves with different orifice diameters, the maximum oil supply rate can be set, providing a process adjustment window for different types of lubricating oils or extreme production speeds. This modular and parameterized design enables the device to flexibly adapt to the production of various specifications of low-smoke halogen-free enameled wires, expanding the application range while ensuring the superiority of core functions, and has high market promotion value.

[0024] Please see Figures 1 to 9 This embodiment provides a production device for low-smoke, halogen-free, and environmentally friendly enameled wire. This device aims to solve the problem of serious oil waste and high cost caused by the oil tank immersion process in the existing enameled wire lubrication process. By integrating a lubrication mechanism with precise coating, adaptive oil quantity adjustment and leak-proof recovery functions, it achieves micro-scale and uniform lubrication coating on the wire surface, significantly improving the lubricant utilization rate and reducing production costs.

[0025] The production device for low-smoke halogen-free environmentally friendly enameled wire includes a fixed frame 11 and a lubrication mechanism and a conveying mechanism 51 installed thereon. The lubrication mechanism is used to lubricate the cooled wire and consists of a clamping assembly 21, an oil receiving assembly 31 and an oil inlet assembly 41. The conveying mechanism 51 is used to provide power for traction of the wire.

[0026] The clamping assembly 21 includes a central tube 22 horizontally fixed to a mounting bracket 11. Two double-sided sleeves 23 are connected to both sides of the central tube 22. Each double-sided sleeve 23 is divided into an upper lubrication chamber 24 and a lower oil collection chamber 25. A hollow pressure plate 26 is coaxially arranged within the lubrication chamber 24. Multiple conveying blades 27 are evenly spaced on the outer wall of the pressure plate 26. A circular groove 28 is formed at the end of each conveying blade 27. The wire 29 to be lubricated passes through the entire central tube 22 and is constrained within the circular grooves 28 on both sides. A head tube 211 and a tail tube 210 are threaded to both ends of the central tube 22, respectively. The wire 29 passes sequentially through the tail tube 210, the central tube 22, and the head tube 211. The central tube 22 is detachably equipped with… The pressure plate 26 is equipped with adjusting tubes 212 of different inner diameters. The tail tube 210 is used to press the adjusting tube 212. The outlet end of the middle tube 22 is provided with a cone head 213. An inner sleeve 214 is coaxially and limitedly installed on the pressure plate 26. The outer periphery of the inner sleeve 214 is connected to an annular contact plate 216 through multiple expansion springs 215. Under the thrust of the compression spring 219, the contact plate 216 and multiple circular grooves 28 together clamp and position the line 29 from the upper and lower sides. The upper port of the lubrication cavity 24 is threadedly installed with a top ring 217. The lower end of the top ring 217 is rotatably provided with a reducing sleeve 218. The upper end of the compression spring 219 abuts against the reducing sleeve 218. The pressure plate 26 is provided with a through tube 220. The lower end of the through tube 220 is connected to the oil receiving cavity 25, and the upper end extends to the top of the pressure plate 26.

[0027] The oil collection assembly 31 includes a collection tray 32 that is slidably and sealably disposed in each oil collection chamber 25. A handle 33 is fixed at the center of the collection tray 32. A bottom ring 34 is threadedly connected to the bottom of the oil collection chamber 25. A push spring 35 is provided between the collection tray 32 and the bottom ring 34.

[0028] The oil inlet assembly 41 includes an oil pipe 42 threaded to the top of the pressure plate 26. The lower end of the oil pipe 42 is connected to the upper end of the through pipe 220. Inside the oil pipe 42, a control plate 43 and a cracking plate 44 are arranged sequentially from top to bottom. A cone block 45 is provided below the central hole of the control plate 43. Multiple counterweight balls 47 are hinged to the cone block 45 by multiple tie rods 46. Multiple sliding grooves 48 are provided on the cracking plate 44 for the counterweight balls 47 to slide in a limited position. A guide rod 49 is fixed to the lower end of the cone block 45. The guide rod 49 is slidably inserted into the guide sleeve 410 fixed on the cracking plate 44. An intermediate spring 411 is provided between the cone block 45 and the cracking plate 44. The upper end of the cone block 45 can also be threaded to a flow-limiting sleeve 412 with different orifice diameters.

[0029] The conveying mechanism 51 includes a motor 52 fixed on the fixed frame 11. The drive wheel 53 at the drive end of the motor 52 transmits friction to the line body 29 through the belt 54, driving it to move continuously.

[0030] The working process and lubrication principle of the device are as follows: First, select the appropriate inner diameter adjustment tube 212 according to the required oil coating thickness, install it into the intermediate tube 22 and lock it with the tail tube 210. Then, the line 29 that has completed the previous process is sequentially inserted into the tail tube 210, adjustment tube 212, pressure plate 26 area and head tube 211. Start the motor 52 and pull the line 29 to move at a uniform speed through the belt 54.

[0031] Under the traction of the line body 29, the clamped line body 29 drives the bonding disc 216 and the pressure plate 26 to rotate synchronously. The multiple conveying blades 27 on the pressure plate 26 rotate accordingly, continuously agitating the lubricating oil accumulated at the bottom of the lubrication chamber 24 and pumping it into the annular gap between the cone head 213 and the line body 29, thereby forming a uniform lubricating film on the surface of the line body 29. The inner diameter of the regulating pipe 212 determines the thickness of the oil film, realizing precise control of the amount of oil applied. The rotation of the pressure plate 26 also serves as the driving source for the oil inlet assembly 41.

[0032] In the oil inlet assembly 41, the rotation of the pressure plate 26 drives the cracking plate 44 and the counterweight ball 47 to rotate synchronously through the internal structure. The centrifugal force generated by the counterweight ball 47 acts on the cone block 45 through the pull rod 46. When the linear speed increases and the rotation speed increases, the centrifugal force increases, which overcomes the elastic force of the intermediate spring 411 and causes the cone block 45 to move downward along the guide rod 49, increasing the annular gap between it and the center hole of the control plate 43, thereby allowing more lubricating oil to flow in from the oil pipe 42. Conversely, when the linear speed decreases, the gap decreases and the oil supply decreases, realizing the adaptive matching between the oil supply rate and the line traction speed. The flow limiting sleeve 412 is used to set the maximum oil supply section to prevent excessive oil supply.

[0033] When it is necessary to change the specifications of the production line or to stop the machine for maintenance, in order to prevent the lubricating oil in the lubrication chamber 24 from leaking, the handles 33 on both sides can be pulled down to compress the push spring 35 of the collection tray 32 and move it downward, thereby expanding the volume of the oil collection chamber 25. The lubricating oil in the lubrication chamber 24 flows into the lower oil collection chamber 25 for temporary storage under the action of gravity through the through pipe 220. After the new production line is threaded, the handles 33 are released, and the push spring 35 pushes the collection tray 32 back to its original position, and the lubricating oil returns to the lubrication chamber 24, effectively preventing oil leakage and waste during the production line change process.

[0034] Working principle summary: This invention utilizes the traction motion of the wire itself to drive the coating and supply circulation of lubricating oil, controls the oil film thickness through a replaceable regulating pipe 212, achieves on-demand oil supply through a centrifugal regulating valve, and prevents oil leakage during machine shutdown through a retractable oil receiving chamber 25 structure, thus forming a high-efficiency, oil-saving and easy-to-operate precision lubrication system for enameled wire.
