Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical covering spinning technology, and in particular to a covering spinning equipment. Background Technology
[0002] Cover spinning is a spinning technology that achieves functional composites through a layered wrapping structure. Covered yarn has a layered composite structure, including a core layer and a covering layer. There are generally two types of covered yarn: air-covered yarn and machine-covered yarn. Air-covered yarn is covered using an air-jet pressurized network, while machine-covered yarn uses mechanical rotation and twisting winding. The most commonly used machine-covered yarn uses a hollow spindle rotating at high speed, where the outer wrapping yarn unwinds and wraps around the core yarn under centrifugal force.
[0003] In the machine-wrapped yarn spinning process, to prevent the synthetic fiber filaments (such as polyester and nylon) and spandex core yarns from rubbing violently against components such as yarn guides and nozzles during high-speed wrapping, oils or lubricants are usually applied to the yarn surface. Additionally, synthetic fibers have strong insulating properties and are prone to accumulating static electricity during processing, leading to fiber scattering, roller entanglement, or dust accumulation. Furthermore, oils can form a lubricating film on the fiber surface, reducing friction damage and the risk of yarn breakage.
[0004] There are several methods for coating yarn surfaces with oil, including guide wheel coating, padding, and spraying, each with its own advantages and disadvantages. Spraying converts liquid into tiny droplets for spraying, resulting in uniform and efficient coating with high material utilization (oil adhesion rate >90%), avoiding waste. Furthermore, spraying is a non-contact method, preventing mechanical friction damage to sensitive materials. However, the oil mist sprayed using this method doesn't always adhere completely to the yarn, and it easily spreads and splashes. Additionally, the droplets and oil mist are significantly affected by airflow during spraying; even a small amount of airflow can exacerbate the oil mist's spread and splashing. Utility Model Content
[0005] In view of this, the purpose of this utility model is to propose a coating spinning device to solve the technical problem that oil mist is easy to spread and splash during the spray oiling process in the prior art.
[0006] To achieve the above objectives, this utility model provides a covering spinning device, including a spindle mounting base for fixing a hollow spindle and a flaring device installed at the front end opening of the hollow spindle. The covering spinning device further includes:
[0007] An atomizing nozzle is fixedly connected to the top of the flaring device, and the atomizing nozzle is angled inward toward the hollow ingot at the center of the inner side of the flaring device;
[0008] A hollow base is fixedly connected to the bottom of the spindle mounting base. The hollow base is filled with lubricating oil, and the atomizing nozzle is connected to the inner cavity of the hollow base.
[0009] An oil drain groove is fixedly connected to the outer end of the bottom of the flaring tool, and the bottom of the oil drain groove is connected to the inner cavity of the hollow base through an oil return pipe.
[0010] Furthermore, the spindle mounting base is provided with an internal pipe, the lower end of which is connected to the inner cavity of the hollow base, and the atomizing nozzle is connected to the upper end of the internal pipe through an oil supply pipe.
[0011] Furthermore, an oil pump is installed inside the hollow base, and the oil pump is connected to an internal pipeline.
[0012] Furthermore, an intermediate air extraction pipe is fixedly connected to the spindle mounting base. The inner end of the intermediate air extraction pipe is connected to the rear opening of the hollow spindle, and the outer end of the intermediate air extraction pipe is connected to an external air extraction machine through an external air extraction pipe.
[0013] Furthermore, a separation chamber is fixedly connected to the outer wall of the spindle mounting base for separating oil mist in the airflow, and the intermediate exhaust pipe and the outer exhaust pipe are both connected to the separation chamber.
[0014] Furthermore, the separation chamber is equipped with several filter membranes, and the connection ports of the intermediate air extraction pipe and the outer air extraction pipe to the separation chamber are located on both sides of the filter membranes.
[0015] Furthermore, a second oil return pipe is fixedly connected to the bottom of the separation chamber. The upper and lower ends of the second oil return pipe are respectively connected to the separation chamber and the inner cavity of the hollow base, and the connection ports of the second oil return pipe and the intermediate air extraction pipe with the separation chamber are located on the same side of the filter membrane.
[0016] Furthermore, the hollow base is also provided with an oil filling port that communicates with the inner cavity of the hollow base.
[0017] The beneficial effects of this utility model are as follows: 1. By installing a flaring device at the front opening of the hollow spindle and mounting the atomizing nozzle for spraying on the top of the flaring device, with the atomizing nozzle angled inward toward the hollow spindle at the center of the inner side of the flaring device, even if the oil mist from the atomizing nozzle does not completely adhere to the core yarn and chemical fiber filaments, it will fall onto the inner wall of the flaring device, greatly reducing the diffusion and splashing of oil mist.
[0018] 2. An intermediate air extraction pipe is installed, with its inner end connected to the rear opening of the hollow spindle. The extraction of air through this pipe creates a backward airflow inside the hollow spindle. This airflow carries oil mist into the spindle, further promoting its adhesion to the core yarn and synthetic filaments. Furthermore, due to this airflow, any external airflow disturbances have a minimal impact, significantly reducing external airflow interference and preventing oil mist from splashing outwards onto the outside of the flaring device.
[0019] 3. An oil drain trough is installed at the bottom outer end of the flaring device. Oil mist falling onto the inner wall of the flaring device accumulates and forms droplets, eventually flowing into the drain trough. The lubricating oil is then returned to the hollow base for storing lubricating oil via a return pipe at the bottom of the drain trough. Additionally, a separation chamber is installed at the end of the intermediate suction pipe to separate oil mist from the airflow. The lubricating oil filtered from the separation chamber is then returned to the hollow base for storing lubricating oil via a second return pipe. This allows oil mist that does not adhere to the core filaments and synthetic fiber filaments to be recycled, further improving lubricating oil utilization and reducing waste.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0029] The first aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, spray oiling in the machine-made yarn weaving process can evenly and efficiently coat the core yarn 01 and chemical fiber filament 02 with oil. However, the oil mist sprayed by the spray method does not completely adhere to the yarn, and the oil mist is easily diffused and splashed. In addition, the droplets and oil mist are greatly affected by airflow interference during spraying; even a small amount of airflow will cause the oil mist to spread and splash more severely. Therefore, this utility model designs a spindle mounting base 101 and a flaring device 103, wherein the spindle mounting base 101 is used to fix the hollow spindle, and the flaring device 103 is installed at the opening at the front end of the hollow spindle.
[0030] Additionally, an atomizing nozzle 104 is fixedly connected to the top of the flaring head 103, with the atomizing nozzle 104 angled inward toward the hollow spindle at the center of the inner side of the flaring head 103. A hollow base 102 is fixedly installed at the bottom of the spindle mounting base 101, the hollow base 102 being filled with lubricating oil, and the atomizing nozzle 104 communicating with the inner cavity of the hollow base 102.
[0031] By installing a flaring device 103 at the front opening of the hollow spindle and mounting an atomizing nozzle 104 for spraying on top of the flaring device 103 with the nozzle 104 angled inward toward the hollow spindle at the center of the inner side of the flaring device 103, the oil mist sprayed by the nozzle 104, even if not all of it adheres to the core filament 01 and the chemical fiber filament 02, will fall onto the inner wall of the flaring device 103, greatly reducing the diffusion and splashing of the oil mist.
[0032] In addition, an intermediate air extraction pipe 108 is fixedly connected to the spindle mounting base 101. The inner end of the intermediate air extraction pipe 108 is connected to the rear opening of the hollow spindle, and the outer end of the intermediate air extraction pipe 108 is connected to an external air extraction machine through an external air extraction pipe 110.
[0033] The central air extraction pipe 108 draws air, creating a backward airflow inside the hollow spindle. This airflow carries oil mist into the hollow spindle, further promoting the adhesion of the oil mist to the core filament 01 and the chemical fiber filament 02. Moreover, due to the presence of this airflow, even if there is external airflow disturbance, the impact on the spindle is minimized, greatly reducing external airflow interference and preventing oil mist from splashing outwards to the outside of the flaring device 103.
[0034] The first aspect of this utility model is as follows: Figure 1 , Figure 3 and Figure 4 As shown, since it is impossible for all the oil mist to adhere to the core filament 01 and the chemical fiber filament 02, this embodiment is provided with a mechanism for recycling and reusing excess oil mist.
[0035] Specifically, an oil leakage groove 106 is fixedly connected to the outer bottom of the flared part 103, and the bottom of the oil leakage groove 106 is connected to the inner cavity of the hollow base 102 through an oil return pipe 107. In addition, a separation chamber 109 is fixedly connected to the outer wall of the spindle mounting base 101 to separate oil mist in the airflow. The intermediate suction pipe 108 and the suction outer pipe 110 are both connected to the separation chamber 109.
[0036] The separation chamber 109 contains several filter membranes 112. The connection ports of the intermediate suction pipe 108 and the outer suction pipe 110 to the separation chamber 109 are located on both sides of the filter membranes 112. A return oil pipe 111 is also fixedly connected to the bottom of the separation chamber 109. The upper and lower ends of the return oil pipe 111 are connected to the inner cavity of the separation chamber 109 and the hollow base 102, respectively. The connection ports of the return oil pipe 111 and the intermediate suction pipe 108 to the separation chamber 109 are located on the same side of the filter membranes 112.
[0037] An oil drain trough 106 is provided at the bottom outer end of the flaring device 103. Oil mist falling on the inner wall of the flaring device 103 accumulates and forms droplets, eventually flowing into the oil drain trough 106. The lubricating oil is then returned to the hollow base 102 for storing lubricating oil through the return oil pipe 107 at the bottom of the oil drain trough 106. In addition, a separation chamber 109 is provided at the end of the intermediate suction pipe 108 to separate oil mist in the airflow, and the lubricating oil filtered in the separation chamber 109 is returned to the hollow base 102 for storing lubricating oil through the return oil pipe 111. This allows oil mist that does not adhere to the core filament 01 and the chemical fiber filament 02 to be recycled, further improving the utilization rate of lubricating oil and reducing waste.
[0038] The lubricating oil flow channel also includes an internal pipe 114 inside the spindle mounting base 101. The lower end of the internal pipe 114 is connected to the inner cavity of the hollow base 102, and the atomizing nozzle 104 is connected to the upper end of the internal pipe 114 through an oil supply pipe. An oil pump 113 is also provided inside the hollow base 102, and the oil pump 113 is connected to the internal pipe 114.
[0039] Preferably, the hollow base 102 is also provided with an oil replenishment port 115 that communicates with the inner cavity of the hollow base 102. After a period of use, it is necessary to replenish lubricating oil into the inner cavity of the hollow base 102 through the oil replenishment port 115, and the oil replenishment port 115 is also sealed to prevent oil vapor from evaporating.
[0040] In summary, this invention, by installing a flaring device 103 at the front opening of the hollow spindle and mounting an atomizing nozzle 104 for spraying on top of the flaring device 103 with the nozzle 104 angled inward toward the hollow spindle at the center of the inner side of the flaring device 103, ensures that even if the oil mist sprayed by the nozzle 104 does not completely adhere to the core filament 01 and the chemical fiber filament 02, it will fall onto the inner wall of the flaring device 103, greatly reducing the diffusion and splashing of the oil mist.
[0041] An intermediate air extraction pipe 108 is provided, with its inner end connected to the rear opening of the hollow spindle. The extraction of air by the intermediate air extraction pipe 108 creates a rearward airflow inside the hollow spindle. This airflow carries oil mist into the hollow spindle, further promoting the adhesion of the oil mist to the core yarn 01 and the chemical fiber filament 02. Moreover, due to the presence of this airflow, even if there is external airflow disturbance, the impact on the spindle is minimized, greatly reducing external airflow interference and preventing oil mist from splashing outwards to the outside of the flaring device 103.
[0042] An oil drain trough 106 is provided at the bottom outer end of the flaring device 103. Oil mist falling on the inner wall of the flaring device 103 accumulates and forms droplets, eventually flowing into the oil drain trough 106. The lubricating oil is then returned to the hollow base 102 for storing lubricating oil through the return oil pipe 107 at the bottom of the oil drain trough 106. In addition, a separation chamber 109 is provided at the end of the intermediate suction pipe 108 to separate oil mist in the airflow, and the lubricating oil filtered in the separation chamber 109 is returned to the hollow base 102 for storing lubricating oil through the return oil pipe 111. This allows oil mist that does not adhere to the core filament 01 and the chemical fiber filament 02 to be recycled, further improving the utilization rate of lubricating oil and reducing waste.
