Description

Technical Field

[0001] This utility model relates to the field of polyester filament production technology, specifically to a polyester filament fiber spinning oiling device. Background Technology

[0002] Polyester filament is made from polyester fibers. Polyester is an important type of synthetic fiber and is the commercial name for polyester fiber in my country. It is a fiber-forming polymer—polyethylene terephthalate (PET)—obtained from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensation reactions. The fiber is then spun and post-treated; oiling is a crucial process in polyester filament spinning.

[0003] Chinese Patent Publication No. CN118547384A discloses an oiling device for polyester filament fiber spinning. The fiber is inserted into the inlet, guided by a guide wheel, and then pulled out from the top of the oiling cylinder and tied to a winding device. During winding, according to the oiling requirements, the motor is turned on, and under the action of teeth and gears, the cover and oil storage box rotate. At the same time, the oil pump is turned on to introduce oil from the connecting pipe into the oil spray nozzle and spray it onto the spinning rotating part for uniform oiling. Conversely, if the oil storage box does not move, oiling is performed uniformly on one side. This solves the problem that existing fiber spinning devices are difficult to uniformly oil according to the oiling requirements.

[0004] The aforementioned patent uses the rotation of the oil reservoir to drive the rotation of the oil nozzle. While this can achieve the goal of uniformly applying oil to the spinning process, the rotation of the oil reservoir generates centrifugal force, causing the oil in the reservoir to move away from the center of the upper oil cylinder. This may result in the oil pump being exposed above the oil surface, causing the oil pump to run dry and the oil nozzle to not spray oil. Especially as the amount of oil used decreases, the total weight of the oil becomes lighter, and the oil will form a larger parabolic structure under the action of centrifugal force, completely adhering to the inner wall of the upper oil cylinder. Although injecting oil into the oil reservoir can reduce the leakage of oil from the pump, it will increase the load on the oil reservoir and increase energy consumption. Utility Model Content

[0005] The purpose of this invention is to provide a polyester filament fiber spinning oiling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A polyester filament fiber spinning oiling device includes an oiling cylinder, a cover rotatably connected to the top of the outer side of the oiling cylinder, an oiling mechanism fixedly connected to the bottom of the cover inside the oiling cylinder, an inlet hole through the outer side of the oiling cylinder, and an outlet tube through the top of the cover. The oil supply mechanism includes an oil reservoir fixedly connected to the bottom of the cover and away from the center of the cover. An oil pump is installed inside the oil reservoir. A housing is fixedly connected to the side of the oil reservoir. Multiple oil nozzles are fixedly connected to the side of the housing at equal intervals. The output end of the oil pump is connected to the inside of the housing. A float is slidably connected inside the oil reservoir. A counterweight is installed on the top of the float. An oil inlet pipe is fixedly connected to the bottom of the float and passes through the top of the oil reservoir and the top of the cover.

[0007] Furthermore, a water, electricity, and gas slip ring is installed on the outside of the wire outlet tube, the oil inlet pipe is connected to the water, electricity, and gas slip ring, and the oil pump is electrically connected to the water, electricity, and gas slip ring.

[0008] Furthermore, both sides of the oil reservoir are fixedly connected to a stabilizing bracket that is also fixedly connected to the cover.

[0009] Furthermore, a fixing ring is fixedly connected to the top side of the oil storage box via a connecting block. The fixing ring has a hollow structure, and multiple nozzles are fixedly connected to the inner wall of the fixing ring at equal angles. An air pipe that penetrates the outer side of the fixing ring and is connected to the sealing cap and the water, electricity, and gas slip ring is fixed through it.

[0010] Furthermore, the upper oil cylinder has a conical shell that is fixed to the oil storage box and two stabilizers at its inner top. The major diameter of the conical shell is smaller than the inner diameter of the upper oil cylinder.

[0011] Furthermore, a gear ring is fixedly connected to the outer side of the cover, and a motor is fixedly connected to the outer side of the upper oil cylinder via a mounting plate. The output end of the motor is fixedly connected to a gear that meshes with the gear ring.

[0012] Furthermore, an oil outlet pipe is fixedly connected to the bottom outer side of the upper oil cylinder, and a switch valve is installed on the outside of the oil outlet pipe. The bottom inner side of the upper oil cylinder is inclined, and a guide wheel is fixedly connected to the inside of the upper oil cylinder through a mounting bracket. A baffle is fixedly connected to the inside of the upper oil cylinder above the guide wheel, and the baffle has a V-shaped structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are: By installing a float and a counterweight in the oil reservoir, the counterweight increases the weight of the float, allowing it to press the oil surface down and prevent the oil from moving the float upward under centrifugal force to form a parabolic structure. This ensures that the oil pump is always submerged in the oil, thus guaranteeing that the injector can always spray oil. By inflating the fixed ring with air and spraying it out from multiple nozzles, the air can be sprayed downwards because the nozzles are tilted downwards. This increases the flow rate of the oil on the spinning surface and minimizes the waste caused by excess oil being moved out of the upper oil cylinder due to the spinning surface being entangled. The conical shell can block the downward-blowing air, preventing the air from the nozzle from disrupting the fuel injection path. In addition, the conical shell can guide the air, causing it to flow out through the gap between the conical shell and the upper oil cylinder, and apply thrust to the oil adhering to the inner wall of the upper oil cylinder, thereby accelerating the flow rate of the oil adhering to the inner wall of the upper oil cylinder.

[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 Figure 1 - Figure 5In this embodiment of the present invention, a polyester filament fiber spinning oiling device includes an oiling cylinder 1, a cover 2 rotatably connected to the top of the outer side of the oiling cylinder 1, an oiling mechanism 3 fixedly connected to the bottom of the cover 2 inside the oiling cylinder 1, a thread inlet hole 11 through the outer side of the oiling cylinder 1, a thread outlet tube 21 through and fixedly connected to the top of the cover 2, and an oil storage box 31 fixedly connected to the bottom of the cover 2 and away from the center of the cover 2. An oil pump 32 is provided inside the oil storage box 31, a housing 33 is fixedly connected to the side of the oil storage box 31, a plurality of oil nozzles 331 are fixedly connected at equal intervals to the side of the housing 33, the output end of the oil pump 32 is connected to the inside of the housing 33, a float 34 is slidably connected inside the oil storage box 31, a counterweight 341 is provided on the top of the float 34, and an oil inlet pipe 35 through and fixedly connected to the top of the oil storage box 31 and the top of the cover 2 is fixedly connected to the bottom of the float 34.

[0018] Specifically, according to Figure 1 As can be seen, the upper oil cylinder 1 is equipped with an arc-shaped door plate. First, the arc-shaped door plate is opened, and then one end of the spinning yarn is inserted through the inlet hole 11 and exits through the outlet tube 21. Then, oil is injected into the oil storage box 31 through the oil inlet pipe 35. As the oil is injected, the float plate 34 and the counterweight 341 float under the action of buoyancy. After a certain amount of oil is injected into the oil storage box 31, the oil storage box 31 can be rotated by rotating the cover 2. At the same time, the oil pump 32 drives a portion of the oil in the oil storage box 31 into the injection shell 33 and sprays it out from multiple oil nozzles 331. Some of the sprayed oil will be adsorbed on the spinning yarn, while the other part of the sprayed oil falls to the bottom of the upper oil cylinder 1 under its own gravity. Due to the rotation of the oil storage box 31, the oil inside will undergo centrifugal motion, but... The float plate 34 and the counterweight 341 press the oil surface down, preventing the oil from shifting and thus avoiding the oil from forming a parabolic tilt under centrifugal force. This ensures that the oil pump 32 is always submerged in the oil, guaranteeing that the injector 331 can always spray oil. Since the oil in the reservoir 31 decreases with use, the operator can periodically add oil to the reservoir 31. This device uses the float plate 34 and counterweight 341 inside the reservoir 31. The counterweight 341 increases the weight of the float plate 34, allowing it to press the oil surface down and preventing the oil from causing the float plate 34 to rise under centrifugal force and form a parabolic tilt. This ensures that the oil pump 32 is always submerged in the oil, guaranteeing that the injector 331 can always spray oil.

[0019] Example 1 like Figure 2 , Figure 4 and Figure 5As shown, in this embodiment, a water, electricity, and gas slip ring 22 is provided on the outside of the wire outlet tube 21, the oil inlet pipe 35 is connected to the water, electricity, and gas slip ring 22, the oil pump 32 is electrically connected to the water, electricity, and gas slip ring 22, and the oil storage box 31 is fixedly connected to the two opposite sides of the sealing cover 2 with a stabilizing frame.

[0020] In this embodiment, the water, electricity, and gas slip ring 22 can be used to connect the wires of the oil inlet pipe 35 and the oil pump 32 to the external oil supply device and power supply respectively, and the wires and oil inlet pipe 35 will not be entangled when the cover 2 rotates (the water, electricity, and gas slip ring 22 is a prior art, and its internal structure and working principle will not be described in detail here). The stability of the oil storage box 31 during rotation can be increased by the two stabilizers.

[0021] Example 2 like Figure 4 and Figure 5 As shown, in this embodiment, a fixing ring 36 is fixedly connected to the top side of the oil storage box 31 via a connecting block. The fixing ring 36 has a hollow structure. Multiple nozzles 361 are fixedly connected to the inner wall of the fixing ring 36 at equal angles. An air pipe that penetrates the cover 2 and is connected to the water, electricity, and gas slip ring 22 is fixed through the outer side of the fixing ring 36. A conical shell 37 is provided at the top inner side of the upper oil cylinder 1, which penetrates and is fixed to the oil storage box 31 and the two stabilizers. The major diameter of the conical shell 37 is smaller than the inner diameter of the upper oil cylinder 1.

[0022] In this embodiment, by connecting one of the interfaces on the water-electric slip ring 22 to an external air source, due to the viscosity of the oil, some of the oil sprayed from the multiple nozzles 331 is adsorbed onto the spinning surface and aggregates with each other. Although the oil on the spinning surface flows downward under its own gravity, the spinning surface will be wound around the spinning surface under the drive of the winding device. Since the oil has viscosity and flows slowly, the spinning surface, driven by the winding device, carries the oil on its surface out of the upper oil cylinder 1, which not only increases oil waste but also affects the winding process due to excessive oil on the spinning surface. This can be addressed by using an air source in conjunction with the water-electric slip ring 22 and the inflation of air into the fixed ring 36, which then sprays the oil from the multiple nozzles 361. Figure 5As shown, the nozzle 361 is tilted downwards, so the sprayed gas can tilt downwards, which can increase the flow rate of the oil on the spinning process and minimize the waste caused by excess oil being moved out of the upper oil cylinder 1 due to the spinning process. The conical shell 37 can block the downward-blowing air and prevent the air sprayed from the nozzle 361 from disturbing the oil spraying path of the nozzle 331. Moreover, the conical shell 37 can guide the air, so that the air flows out of the gap between the conical shell 37 and the upper oil cylinder 1, and applies a thrust to the oil adhering to the inner wall of the upper oil cylinder 1, thereby accelerating the flow rate of the oil adhering to the inner wall of the upper oil cylinder 1 (when the nozzle 331 sprays oil, most of the oil comes into contact with the inner wall of the upper oil cylinder 1, so the inner wall of the upper oil cylinder 1 will be adhering to the oil).

[0023] Example 3 like Figure 2 - Figure 4 As shown, in this embodiment, a gear ring 23 is fixedly connected to the outer side of the cover 2, and a motor 13 is fixedly connected to the outer side of the upper oil cylinder 1 through a mounting plate. A gear 14 that meshes with the gear ring 23 is fixedly connected to the output end of the motor 13. An oil outlet pipe 12 is fixedly connected through the bottom of the outer side of the upper oil cylinder 1. A switch valve is provided on the outer side of the oil outlet pipe 12. The bottom of the inner side of the upper oil cylinder 1 is inclined. A guide wheel 15 is fixedly connected to the inside of the upper oil cylinder 1 through a mounting bracket. A baffle 16 is fixedly connected to the inside of the upper oil cylinder 1 and above the guide wheel 15. The baffle 16 has a V-shaped structure.

[0024] In this embodiment, the motor 13 drives the gear 14 to rotate the gear ring 23, which in turn rotates the cover 2. The rotating cover 2 can drive the oil storage box 31 to rotate along the axis of the cover 2, so that the oil sprayed from the oil nozzle 331 can be more evenly adsorbed on the spinning surface. The guide wheel 15 can guide the spinning. The baffle 16, which has a V-shaped structure, can prevent the dripping oil from flowing out of the inlet hole 11. The oil collected at the bottom of the upper oil cylinder 1 can be recovered through the oil outlet pipe 12.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
