Description

Technical Field

[0001] This utility model relates to the field of wire guide technology, specifically a wire guide with an adaptive lubrication structure. Background Technology

[0002] In industrial fields such as textiles, metal processing, and cable manufacturing, where the guidance and transmission of yarn are required, the yarn guide is the core component that ensures the yarn runs smoothly along a preset path. During high-speed movement, the yarn continuously rubs against the guide wheels and other contact parts of the yarn guide. If the guide wheels are not lubricated in time, the following problems will occur directly: First, the yarn surface will develop quality defects such as fuzzing and broken yarn due to increased friction. Especially for high-precision yarn, even minor damage can affect the performance of the final product. Second, rotating parts such as the guide wheel shaft will wear out faster due to long-term dry friction or insufficient lubrication, shortening the service life of the equipment and increasing maintenance costs. Currently, the industry mainly uses two methods for lubricating yarn guides: one is manual periodic application of lubricant. This method relies on the operator's experience and has problems such as uneven lubrication intervals and difficulty in accurately controlling the dosage. In high-speed production lines, it is easy for lubrication to be untimely due to the lag in manual operation. The other is to use a mechanical lubrication device with fixed parameters to achieve lubrication by distributing lubricant at timed and quantitative intervals. However, this type of device cannot respond to the dynamic changes in the yarn's operating state. When the yarn speed increases and the tension increases, the friction intensity increases accordingly, and the required amount of lubricant increases accordingly. However, the fixed device still maintains the original output, resulting in insufficient lubrication. When the yarn speed decreases, excessive lubricant will cause waste and pollution. Therefore, developing a wire guide structure that can adaptively adjust the lubrication amount according to the operating conditions of the wire is of great significance for improving the quality of wire processing, reducing equipment wear and labor costs. Utility Model Content

[0003] The purpose of this invention is to provide a wire guide with an adaptive lubrication structure to solve the problems mentioned in the background art, such as the defects of artificial lubrication and the inability of mechanical lubrication to be adaptively adjusted.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wire guide with an adaptive lubrication structure, comprising a base plate, a column and a mounting column fixedly disposed on the upper surface of the base plate, a guide wheel rotatably mounted on the upper end of the column, a rotating gear mounted on the outer surface of the upper end of the mounting column, a lever fixedly disposed on the outer surface of one end of the gear's shaft, a liquid storage tank fixedly disposed on the upper surface of the base plate below the gear, and a liquid outlet pipe fixedly connected to one end of the liquid storage tank; A liquid injection port is fixedly installed on the lower outer surface of one side of the liquid storage tank, and a sliding piston plate is provided inside the liquid storage tank. The upper end of the piston plate penetrates the upper surface of the liquid storage tank, and a contact plate is fixedly connected to the upper end of the piston plate. A first one-way valve is installed on the outer surface of one end of the piston plate. A partition plate is fixedly installed inside one end of the liquid storage tank. A second one-way valve is fixedly installed at the end of the liquid outlet pipe connected to the liquid storage tank. A diversion groove is opened inside the upper end of the column, and the inner surface of the diversion groove is penetrated by one end of the liquid injection hole. The other end of the liquid injection hole penetrates the inner surface of the upper end of the column. An adjusting rod is mounted on the outer surface of the guide wheel, and one end of the adjusting rod is rotatably connected to a pawl.

[0005] Preferably, the lever is a ball-head design and is located directly above the contact plate.

[0006] By adopting the above technical solution, the ball head design can reduce frictional damage when the lever contacts the contact plate, and the lever is located directly above the contact plate, which can ensure that the lever can accurately and stably periodically move the contact plate when the gear rotates, providing a reliable trigger for the sliding of the piston plate.

[0007] Preferably, the outer surface of the piston plate is in contact with the inner surface of the liquid storage tank and one outer surface of the contact plate, and a spring is connected between the piston plate and the liquid storage tank.

[0008] The above technical solution ensures the sealing of the internal space of the reservoir by fitting the piston plate with the inside of the reservoir, thus preventing lubricant leakage. The spring between the piston plate and the reservoir can drive the piston plate to return to its original position after the lever disengages from the contact plate, preparing for the next lever to output lubricant, thus forming a reciprocating cycle.

[0009] Preferably, the lower end of the outlet pipe penetrates the upper outer surface of the storage tank, and the lower end of the outlet pipe is located on the side of the partition plate facing away from the contact plate, and the lower end of the outlet pipe is located inside the lower end of the storage tank, while the upper end of the outlet pipe penetrates the inner surface of the diversion channel.

[0010] By adopting the above technical solution, the lower end of the outlet pipe is located inside the lower end of the storage tank and on the side of the partition plate facing away from the contact plate, which can ensure that the lubricating fluid in the storage tank can be fully extracted and output, reducing residue. The upper end passes through the diversion groove, which can accurately guide the output lubricating fluid into the diversion groove, and then deliver it to the lubrication part of the guide wheel through the injection hole, ensuring the effective transmission of lubricating fluid.

[0011] Preferably, the adjusting rod and the guide wheel are threadedly connected, the actuating teeth and the guide wheel are slidably connected, and the actuating teeth are evenly distributed.

[0012] By adopting the above technical solution, the threaded connection between the adjusting rod and the guide wheel allows the actuating teeth to slide along the guide wheel when the adjusting rod is rotated, thereby adjusting the number of meshing teeth and gears. The sliding connection and equal spacing of the actuating teeth ensure the stability of the meshing state, making it easy to accurately adjust the output of lubricating fluid per cycle according to actual working conditions and improving the adaptability of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the wire guide equipped with an adaptive lubrication structure: 1. Through the adjusting rod installed on the outer surface of the guide wheel and the actuating tooth rotatably connected to one end of the adjusting rod, when the wire drives the guide wheel to rotate, the adjusting rod will drive the actuating tooth to move, which in turn drives the gear on the outer surface of the upper end of the mounting column to rotate. The lever on the outer surface of one end of the gear shaft rotates with the gear and periodically actuates the contact plate above the liquid storage tank, causing the piston plate connected to the lower end of the contact plate to slide in the liquid storage tank. Since the rotation speed of the guide wheel is related to the running speed of the wire, when the wire speed is high, the rotation speed of the guide wheel is high, the frequency of the lever actuating the contact plate increases, and the sliding frequency of the piston plate also increases, thereby increasing the output of lubricating fluid. When the wire speed decreases, the output decreases accordingly. This solves the problem that fixed parameter mechanical lubrication devices cannot respond to dynamic changes in the running state of the wire and avoids insufficient or excessive lubrication. 2. The upper end of the outlet pipe connected to one end of the liquid storage tank passes through the diversion groove inside the upper end of the column. The diversion groove is connected to the contact part of the guide wheel through the injection hole. The lubricating fluid output from the outlet pipe can be accurately delivered to the position of the guide wheel that needs lubrication through the diversion groove and the injection hole, ensuring the lubrication effect. At the same time, the first one-way valve on the outer surface of one end of the piston plate and the second one-way valve at the connection end of the outlet pipe and the liquid storage tank ensure that the lubricating fluid can only be output from the liquid storage tank through the outlet pipe, avoiding backflow, making the lubricating fluid supply stable, and reducing quality defects such as fuzzing and broken wires on the surface of the wire caused by improper lubrication. This is especially beneficial for the processing of high-precision wires. 3. The filling port at the lower end of one side of the storage tank facilitates the addition of lubricating fluid. The threaded connection between the adjusting rod and the guide wheel, as well as the sliding connection between the actuating teeth and the guide wheel, allows the number of engagements of the actuating teeth and gears at a time to be adjusted according to actual needs, thereby manually adjusting the liquid output at a time to adapt to different working conditions.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-6 This utility model provides a technical solution: a wire guide with an adaptive lubrication structure.

[0018] Example 1: This example discloses: a base plate 1, on the upper surface of the base plate 1 are fixedly provided a column 2 and a mounting column 4, a guide wheel 3 is rotatably installed on the upper end of the column 2, a rotating gear 5 is installed on the outer surface of the upper end of the mounting column 4, a lever 6 is fixedly provided on the outer surface of one end of the shaft of the gear 5, a liquid storage tank 7 is fixedly provided on the upper surface of the base plate 1 below the gear 5, and a liquid outlet pipe 13 is fixedly connected to one end of the liquid storage tank 7; The lever 6 is a ball-head lever design, and the lever 6 is located directly above the contact plate 10; The base plate 1 provides stable support for the overall structure. The upper end of the column 2 fixed on its surface is rotatably mounted with guide wheel 3. When the wire is transmitted, the wire contacts the guide wheel 3 and drives the guide wheel 3 to rotate around the column 2. The mounting column 4 is fixed on the base plate 1, and a rotatable gear 5 is mounted on the outer side of its upper end. The gear 5 rotates with the linkage of the guide wheel 3. One end of the shaft of gear 5 is fixed with a lever 6 with a ball head design. When the lever 6 rotates with gear 5, it will periodically exert a downward pushing force on the contact plate 10 because it is located directly above the contact plate 10 above the liquid storage tank 7. The liquid storage tank 7 is fixed on the base plate 1 and located below gear 5. The liquid outlet pipe 13 connected to one end provides a channel for the output of lubricating fluid. During this process, the rotational speed of the guide wheel 3 is directly related to the running speed of the wire. The faster the wire speed, the higher the rotational speed of the guide wheel 3, and the higher the rotational frequency of the gear 5 and the lever 6. The frequency of the lever 6 moving the contact plate 10 increases accordingly, providing a mechanical triggering basis for the dynamic adjustment of the subsequent lubricant output.

[0019] Example 2: This example is based on Example 1: A liquid injection port 8 is fixedly installed on the lower outer surface of one side of the liquid storage tank 7, and a sliding piston plate 9 is provided inside the liquid storage tank 7. The upper end of the piston plate 9 penetrates the upper surface of the liquid storage tank 7, and a contact plate 10 is fixedly connected to the upper end of the piston plate 9. A first one-way valve 11 is installed on the outer surface of one end of the piston plate 9. A partition plate 12 is fixedly installed inside one end of the liquid storage tank 7. A second one-way valve 14 is fixedly installed at the end of the liquid outlet pipe 13 connected to the liquid storage tank 7. A diversion groove 15 is opened inside the upper end of the column 2, and the inner surface of the diversion groove 15 is penetrated by one end of the liquid injection hole 16. The other end of the liquid injection hole 16 penetrates the inner surface of the upper end of the column 2. The outer surface of the piston plate 9 is in contact with the inner surface of the liquid storage tank 7 and one outer surface of the contact plate 10, and a spring is connected between the piston plate 9 and the liquid storage tank 7. The lower end of the outlet pipe 13 penetrates the upper outer surface of the storage tank 7, and the lower end of the outlet pipe 13 is located on the side of the partition plate 12 facing away from the contact plate 10. The lower end of the outlet pipe 13 is located inside the lower end of the storage tank 7, and the upper end of the outlet pipe 13 penetrates the inner surface of the diversion channel 15. The injection port 8 at the lower end of one side of the reservoir 7 is used to replenish the lubricant. The piston plate 9, which is slidably disposed inside, is attached to the inner side of the reservoir 7 and the side of the contact plate 10. A spring is connected between the piston plate 9 and the reservoir 7. When the lever 6 in Embodiment 1 moves the contact plate 10, the contact plate 10 drives the piston plate 9 to slide downward in the reservoir 7, compressing the space below it. After the lever 6 is disengaged, the piston plate 9 returns to its original position under the action of the spring. The partition plate 12 inside the liquid storage tank 7 divides the internal space. The first one-way valve 11 at one end of the piston plate 9 only allows air to flow into the area between the partition plate 12 and the piston plate 9 from above when the piston plate 9 is reset. The second one-way valve 14 at the connection end of the liquid outlet pipe 13 and the liquid storage tank 7 only allows lubricating fluid to flow out from this area through the liquid outlet pipe 13 when the piston plate 9 is pressed down. The upper end of the outlet pipe 13 passes through the diversion groove 15 inside the upper end of the column 2. After the lubricant enters the diversion groove 15, it is accurately delivered to the contact part between the guide wheel 3 and the wire through the injection hole 16 that passes through the diversion groove 15 and the inner side of the upper end of the column 2. The cooperation of the first one-way valve 11 and the second one-way valve 14 prevents the lubricant from flowing back and ensures stable output. The diversion groove 15 and the injection hole 16 ensure that the lubricant reaches the friction part directly, reducing waste and wire quality defects.

[0020] Example 3: This example is based on Example 1 and Example 2: An adjusting rod 17 is installed on the outer surface of the guide wheel 3, and one end of the adjusting rod 17 is rotatably connected to a toggle tooth 18; The adjusting rod 17 is threadedly connected to the guide wheel 3, and the actuating teeth 18 are slidably connected to the guide wheel 3, with the actuating teeth 18 being evenly distributed. By adjusting the number of meshes between the actuating teeth 18 and the gear 5 using the adjusting rod 17, the stroke of the piston plate 9 can be manually controlled in a single slide. The more meshes, the larger the single rotation angle of the gear 5, the greater the downward pressure of the piston plate 9, and the greater the single liquid output. This allows the device to manually fine-tune the single liquid output based on different working conditions such as the material and tension of the wire, on the basis of self-adaptation. This avoids the inadequacy of a single self-adaptive mode for special working conditions and further reduces the risk of excessive or insufficient lubrication.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
