Description

Technical Field

[0001] This utility model relates to the field of textile production, and more specifically, to an auxiliary oiling device for a spinning machine. Background Technology

[0002] The fiber drawing machine is a core piece of equipment for processing high-molecular polymers into continuous fibers, and it is widely used in textiles, clothing, industrial textiles, packaging materials, and other fields. Its core function is to extrude polymer melt or solution into fine streams through processes such as melt spinning and solution spinning, which are then cooled and solidified to form fibers. Subsequent processes such as drawing and winding are then completed. Oiling the fibers is a crucial step in the fiber drawing process, but traditional oiling processes still have the following drawbacks:

[0003] (1) In the traditional oiling process, if manual oiling is used, the manuals need to apply or soak the yarn one by one or bundle by bundle. Especially in large-scale production, a lot of manpower is required and the operation cycle is long. It is difficult to match the high-speed spinning machine equipment. If the oiling method is used, the oil consumption is large and it is easy to cause the fiber to absorb too much oil. The subsequent drying process is required, which increases energy consumption.

[0004] (2) The oiling components of traditional devices are in a fixed position, which makes it difficult to adapt to the changes in the fiber path during different spinning processes. This can easily lead to uneven oil distribution on the surface of the yarn, affecting the lubrication effect, gloss, and subsequent processing of the fiber. To address this, an auxiliary oiling device for spinning machines is proposed. Utility Model Content

[0005] The purpose of this invention is to address the problems in the current traditional oiling process, where manual oiling requires applying or soaking each thread or bundle individually. This is especially problematic in large-scale production, where it requires a large amount of manpower and has a long operation cycle, making it difficult to match with high-speed spinning machines. If the oiling method is used, the oil consumption is large and it is easy for the fibers to absorb too much oil, requiring additional drying treatment afterward, which increases energy consumption.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] The present invention is as follows: an auxiliary oiling device for a spinning machine, comprising a bracket, a limiting mechanism for adjusting the oiling angle and position is provided on the side wall of the bracket, an oiling component for oiling the drawn fibers is provided on the limiting mechanism, and an oiling component for supplying lubricating oil to the oiling component is provided on the oiling component.

[0008] The limiting mechanism includes an extension rod welded to the side wall of the support. The end of the extension rod away from the support is rotatably connected to a telescopic outer tube. The side wall of the telescopic outer tube is threaded with limiting bolts. There are two limiting bolts. A telescopic inner tube is nested inside the telescopic outer tube. The telescopic inner tube is limited by the limiting bolts.

[0009] As a preferred technical solution of this utility model, the oiling assembly includes a V-shaped plate welded to the end of the telescopic inner tube away from the extension rod, a fixing bolt is provided at the bottom of the V-shaped plate, the number of fixing bolts is three, a fixing plate is bolted to the bottom of the V-shaped plate, the V-shaped plate and the fixing plate are bolted together by fixing bolts, and an oil-absorbing felt is provided between the V-shaped plate and the fixing plate.

[0010] As a preferred technical solution of this utility model, the oil conveying assembly includes an oil conveying pipe fixedly connected to the surface of the V-shaped plate. A nozzle is provided at one end of the oil conveying pipe near the oil-absorbing felt, and an electric oil pump is connected to the other end of the oil conveying pipe away from the oil-absorbing felt. An oil tank is fixedly connected to the input end of the electric oil pump.

[0011] As a preferred technical solution of this utility model, a control panel is provided on the side wall of the bracket, the control panel has a built-in PLC control system, and the control panel is electrofused to the electric oil pump.

[0012] As a preferred technical solution of this utility model, a liquid level sensor is provided on the top of the oil tank, and the liquid level sensor has a built-in alarm.

[0013] As a preferred technical solution of this utility model, a wear-resistant layer is provided on the contact surface between the telescopic outer tube and the telescopic inner tube, and the wear-resistant layer is made of polytetrafluoroethylene and has a thickness of 0.3-0.5mm.

[0014] As a preferred technical solution of this utility model, the V-shaped plate and the fixing plate are made of zinc alloy.

With the oiling assembly in place, the V-shaped plate is fixedly connected to the telescopic inner tube by welding during use, and the bottom is fixed by three fixing bolts to form a stable structure, which ensures the installation angle of the oil-absorbing felt and facilitates disassembly and maintenance. The oil-absorbing felt has a porous fiber structure, which can absorb a large amount of lubricating oil and release it slowly to form a uniform oil film. At the same time, the oil-absorbing felt is soft and will not cause mechanical damage when it comes into contact with the threads.

[0017] 2. With the setting of the limiting mechanism, during use, the telescopic outer tube can rotate around the end of the extension rod, and the telescopic inner tube can slide axially inside the telescopic outer tube and be fixed in position by two limiting bolts, so as to realize the angle adjustment perpendicular to the plane of the support and the horizontal distance adjustment, to meet the production needs of different specifications of wire.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] like Figure 1 As shown, this embodiment proposes an auxiliary oiling device for a fiber drawing machine, including a bracket 1. A limiting mechanism 2 for adjusting the oiling angle and position is provided on the side wall of the bracket 1. An oiling component 3 for oiling the drawn fibers is provided on the limiting mechanism 2. An oil supply component 4 for supplying lubricating oil to the oiling component is provided on the oiling component 3.

[0030] like Figure 2 and Figure 3 As shown, the limiting mechanism 2 includes an extension rod 201 welded to the side wall of the support 1. The extension rod 201 is fixed to the side wall of the support 1 by welding, providing a basic support structure. The end of the extension rod 201 away from the support 1 is rotatably connected to a telescopic outer tube 202. The side wall of the telescopic outer tube 202 is threaded with limiting bolts 204. There are two limiting bolts 204. A telescopic inner tube 203 is nested inside the telescopic outer tube 202. The telescopic inner tube 203 is limited by the limiting bolts 204. The telescopic outer tube 202 is rotatably connected to the extension rod 201, which can achieve 360° rotation to adjust the oiling angle. The telescopic inner tube 203 is nested inside the telescopic outer tube 202. By loosening and tightening the limiting bolts 204, it can freely extend and retract and lock its position to adapt to the width and oiling position requirements of different wire drawing machines. In use, the angle of the device is adjusted by rotating the telescopic outer tube 202, which is rotatably connected to the extension rod 201. Then, the limit bolt 204 is loosened, the length of the telescopic inner tube 203 is adjusted so that the telescopic inner tube 203 reaches the appropriate position, and the limit bolt 204 is tightened.

[0031] like Figure 5As shown, the oiling assembly 3 includes a V-shaped plate 301 welded to the end of the telescopic inner tube 203 away from the extension rod 201. Three fixing bolts 302 are provided at the bottom of the V-shaped plate 301. A fixing plate 303 is bolted to the bottom of the V-shaped plate 301. The V-shaped plate 301 and the fixing plate 303 are connected by the fixing bolts 302. The V-shaped plate 301 and the fixing plate 303 are clamped together by the three fixing bolts 302 to form an oiling contact surface. The oil-absorbing felt 304 is placed between the V-shaped plate 301 and the fixing plate 303. The oil-absorbing felt 304 absorbs lubricating oil through capillary action, ensuring uniform oiling when in contact with the thread. In use, the fixing bolts 302 are loosened, the oil-absorbing felt 304 is placed between the V-shaped plate 301 and the fixing plate 303, and then the fixing bolts 302 are tightened to form the oiling contact surface.

[0032] like Figure 2 As shown, the oil delivery assembly 4 includes an oil delivery pipe 401 fixedly connected to the surface of the V-shaped plate 301. A nozzle 402 is installed at one end of the oil delivery pipe 401 near the oil-absorbing felt 304, and an electric oil pump 403 is connected to the other end of the oil delivery pipe 401 away from the oil-absorbing felt 304. An oil tank 404 is fixedly connected to the input end of the electric oil pump 403. The electric oil pump 403 draws lubricating oil from the oil tank 404 and delivers it to the nozzle 402 through the oil delivery pipe 401. The nozzle 402 atomizes or drips the lubricating oil onto the oil-absorbing felt 304, keeping it moist. In use, the electric oil pump 403 is started, drawing lubricating oil from the oil tank 404 and delivering it through the oil delivery pipe 401. The lubricating oil is then atomized or dripped onto the oil-absorbing felt 304 through the nozzle 402, where it absorbs the lubricating oil through capillary action.

[0033] like Figure 6 As shown, a control panel 5 is installed on the side wall of the bracket 1. The control panel 5 has a built-in PLC control system and is electrically connected to the electric oil pump 403. In use, the PLC control system adjusts the flow rate and start / stop time of the electric oil pump 403 through the control panel 5 to achieve precise oil supply.

[0034] like Figure 1 As shown, a liquid level sensor 6 is installed on the top of the oil tank 404, and the liquid level sensor 6 has a built-in alarm. During use, the liquid level sensor 6 monitors the oil level in the oil tank 404 in real time, and triggers the alarm to remind you to add lubricating oil when the level is below the threshold.

[0035] like Figure 3 As shown, a wear-resistant layer is provided on the contact surface between the telescopic outer tube 202 and the telescopic inner tube 203. The wear-resistant layer is made of polytetrafluoroethylene and has a thickness of 0.3-0.5 mm. During use, the polytetrafluoroethylene wear-resistant layer on the contact surface between the telescopic outer tube 202 and the telescopic inner tube 203 reduces the coefficient of friction, reduces wear, and extends service life.

[0036] like Figure 5 As shown, the V-shaped plate 301 and the fixing plate 303 are made of zinc alloy. In use, the zinc alloy material of the V-shaped plate 301 and the fixing plate 303 provides corrosion resistance, high strength, and prevents deformation caused by lubricating oil corrosion and mechanical vibration.

[0037] Specifically, when using the auxiliary oiling device for this wire drawing machine: During use, adjust the angle of the device by rotating the telescopic outer tube 202, which is rotatably connected to the extension rod 201. Then, loosen the limiting bolt 204, adjust the length of the telescopic inner tube 203 to achieve the appropriate position, and tighten the limiting bolt 204 (e.g., ...). Figure 2 and Figure 3 (As shown), then loosen the fixing bolt 302, place the oil-absorbing felt 304 between the V-shaped plate 301 and the fixing plate 303, and then tighten the fixing bolt 302 to form an oil-applying contact surface (as shown). Figure 5 As shown), the PLC control system then adjusts the flow rate and start / stop time of the electric oil pump 403 via the control panel 5 to achieve precise oil supply (e.g., Figure 6 (As shown), then the electric oil pump 403 is started. The electric oil pump 403 draws lubricating oil from the oil tank 404 and, through the oil delivery pipe 401, atomizes or drips the lubricating oil onto the oil-absorbing felt 304 through the nozzle 402. The oil-absorbing felt 304 absorbs the lubricating oil through capillary action (as shown). Figure 2 As shown), the level sensor 6 monitors the oil level in tank 404 in real time. When the level falls below the threshold, an alarm is triggered to remind the user to add lubricating oil (e.g., ...). Figure 1 (As shown).

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
