Description

Technical Field

[0001] This invention relates to the field of textile machinery and equipment technology, and more specifically, to an oiling device for a texturing machine and its oiling control method. Background Technology

[0002] The oiling device is one of the important structural components of the texturing machine. Existing texturing machines have three abnormal states of oiling: uneven, insufficient, and excessive. Insufficient oiling will lead to a comprehensive decrease in the lubricity, antistatic properties, and cohesion of the fiber filaments. Excessive oiling will result in an excessively thick oil film on the surface of the filaments, disrupting the process balance and causing problems such as adhesion, poor shaping, and contamination. Uneven oiling is a hidden hazard that will lead to poor product quality consistency. Existing texturing machines have difficulties in controlling oiling, which urgently needs to be solved. Based on the problems reported by the workshop, the company will improve and design a new oiling device to meet production needs. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an oiling device for a texturing machine and its oiling control method. This invention designs a novel oiler structure. The input oil will form a continuous oil curtain in the oiling channel of the bending section. After the fiber passes through the oil curtain, it can form a uniform oiling effect. This invention designs an oiling amount control method. The oiling amount of the oiler can be controllably adjusted according to the fiber speed and fiber type to solve the problem of insufficient or excessive oiling.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An oiling device for a texturing machine includes an oiler and an oil tank assembly. The oiler is mounted on top of the oil tank assembly and is V-shaped. The oiler includes a first inclined section and a second inclined section, with a bend connecting the first and second inclined sections. A transversely penetrating thread hole is provided in the center of the bend connecting section, through which the fiber filaments are transversely transmitted. The oil tank assembly is connected to the first inclined section via a pipeline. Oil is input from the first inclined section and flows in the direction of the bend connecting section and the second inclined section. The oil provides an oiling effect on the fiber filaments passing through the thread hole.

[0006] Furthermore, the first inclined section has an oil inlet channel, and an oil replenishment pipe joint is installed at the starting end of the oil inlet channel. The bent section has an oil supply channel, and the threading hole is located in the center of the oil supply channel. The second inclined section has an oil discharge channel, and the two ends of the oil supply channel are respectively connected to the oil inlet channel and the oil discharge channel.

[0007] Furthermore, the oil inlet channel is a non-open channel, and the oil supply channel and oil discharge channel are semi-open channels.

[0008] Furthermore, the tilt angle of the first tilt segment is greater than the tilt angle of the second tilt segment.

[0009] Furthermore, a support foot is installed at the bottom of the second inclined section, and the oiler is mounted above the oil tank assembly via the support foot bracket. An oil guide plate is connected and installed on the side of the support foot, and the oil guide plate is installed at an inclined direction. The oil guide plate is located below the outlet end of the oil discharge channel.

[0010] Furthermore, the oil tank assembly includes a horizontally parallel-installed recovery oil tank and a replenishment oil tank. The oiler is installed within the recovery oil tank. A through-hole is provided between the recovery oil tank and the replenishment oil tank, and the recovery oil tank and the replenishment oil tank are connected through the through-hole. A filter element is installed in the recovery oil tank, and the filter element covers the through-hole. A metering pump is installed in the replenishment oil tank, and the outlet pipe of the metering pump is connected to the replenishment oil pipe joint.

[0011] Furthermore, the filter element is a filter plate, and the filter element is installed at an angle.

[0012] An oiling control method, applied to an oiling device for a texturing machine, includes the following steps:

[0013] Step S1: Calculate the denier of a single fiber filament based on the type of fiber filament. Set the denier of a single fiber filament as D. Determine the target oiling rate based on the type of fiber filament. Set the target oiling rate as ω.

[0014] Step S2: Measure the wire feeding speed of the texturing machine's traction roller, and set the wire feeding speed as V;

[0019] This invention features a novel oiler structure. The input oil forms a continuous oil curtain in the oiling channel of the bending section. After passing through the oil curtain, the fibers achieve a uniform oiling effect. This invention also includes an oiling quantity control method, allowing the oiling quantity of the oiler to be controllably adjusted according to the fiber speed and fiber type to solve the problems of insufficient or excessive oiling.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1-3 The illustrated texturing machine oiling device includes an oiler 1 and an oil tank assembly 2. The oiler 1 is mounted above the oil tank assembly 2 and is used for oiling fiber filaments. The oiler 1 is V-shaped and installed laterally. The oiler 1 includes a first inclined section 11 and a second inclined section 12, with a bent connecting section 13 connecting the first inclined section 11 and the second inclined section 12. A transverse through-hole 14 is opened in the center of the bent connecting section 13. Guide wheels 3 are installed on both the left and right sides of the oiler 1. The guide wheel 3 guides the fiber filaments to pass horizontally through the threading hole 14. The oil tank assembly 2 is used to provide the oil required for oiling. The oil tank assembly 2 is connected to the first inclined section 11. The oil is input from the first inclined section 11 and flows along the natural inclination. The flow direction is sequentially the first inclined section 11, the bend section 13 and the second inclined section 12, and finally falls back to the oil tank assembly 2. At the bend section 13, the oil forms an oil curtain effect, so that the oil forms an oiling effect on the fiber filaments passing through the threading hole 14.

[0026] like Figure 2 and Figure 3As shown, the first inclined section 11 has an oil inlet channel 111, and an oil replenishment pipe joint 112 is installed at the starting end of the oil inlet channel 111. The oil is input from the oil replenishment pipe joint 112 and flows naturally down along the oil inlet channel 111. The bent section 13 has an oil supply channel 131, and the thread-passing hole 14 is located in the center of the oil supply channel 131. The oil forms a full oil curtain effect in the oil supply channel 131, and the passing fibers are fully covered, so that the oil is evenly applied around their circumference. The second inclined section 12 has an oil discharge channel. The two ends of the oil inlet channel 121 and the oil outlet channel 131 are respectively connected to the oil inlet channel 111 and the oil outlet channel 121. Finally, the oil is discharged outward from the oil outlet channel 121. In order to ensure that the oil can smoothly reach the oil inlet channel 131, the present invention sets the oil inlet channel 111 as a non-open channel to prevent the oil from falling due to gravity in the middle. The oil inlet channel 131 and the oil outlet channel 121 do not have the above-mentioned problem of falling due to gravity. Therefore, the oil inlet channel 131 and the oil outlet channel 121 are set as semi-open channels.

[0027] To ensure that the oil forms a full oil curtain effect within the oil supply channel 131, such as Figure 3 As shown, the inclination angle of the first inclined section 11 is greater than that of the second inclined section 12. The inclination angle of the first inclined section 11 is 40 degrees upward and the inclination angle of the second inclined section 12 is 7 degrees downward. Under the above design, the oil input rate is fast and the output rate is low. That is to say, the oil in the oil discharge channel 121 is pushed down. In this way, the congestion point of the oil is exactly at the position of the oil supply channel 131, ensuring that a full and continuous oil curtain is formed in the oil supply channel 131. This ensures that the fibers passing through the oil supply channel 131 can be evenly and fully oiled.

[0028] like Figure 1As shown, a support leg 15 is installed at the bottom of the second inclined section 12. The oiler 1 is mounted on top of the oil tank assembly 2 via the support leg 15. The support leg 15 supports the installation of the oiler 1. An oil guide plate 151 is connected and installed on the side of the support leg 15. The oil guide plate 151 is installed at an incline and is located below the outlet end of the oil discharge channel 121. The oil guide plate 151 serves to guide the oil back down and buffers the oil to prevent splashing. The oil tank assembly 2 includes a horizontally parallel oil recovery tank 21 and an oil replenishment tank 22. The oiler 1 is installed within the range of the oil recovery tank 21. Excess oil after the oiling operation is recovered through the oil recovery tank 21. A through-hole 23 is provided between the oil recovery tank 21 and the oil replenishment tank 22, connecting them. The recovered oil can be reused in the replenishment tank 22. However, since the recovered oil has come into contact with fibers, there will be fine lint, which will cause pipeline blockage. Therefore, a filter element 24 is installed in the recovery tank 21 to filter out the fine lint in the oil, ensuring that the reused oil is clean. The filter element 24 covers the through-hole 23 and is a filter plate. The filter element 24 is installed at an angle to increase the filtration area and prevent the filter from clogging too quickly. The replenishment tank 22 is equipped with a metering pump 25. The outlet pipe of the metering pump 25 is connected to the replenishment pipe connector 112. The metering pump 25 can accurately draw a certain amount of oil to the oiler 1. During the oiling operation, there will be some loss of oil. When the loss is large, clean oil needs to be added. The clean oil is directly added to the replenishment tank 22.

[0029] During the oiling process, it is also necessary to control the amount of oil applied to the fibers per unit time by the oiler 1. Therefore, this invention designs an oiling control method, which is applied to the aforementioned texturing machine oiling device, and includes the following steps:

[0030] Step S1: Calculate the denier of a single fiber filament based on the fiber type. Denier is a fineness index of fiber filament, a unit of weight used in the textile industry to express the fineness of fibers or yarns. It is defined as the weight (in grams) of 9000 meters of fiber filament at a standard moisture regain. Let the denier of a single fiber filament be D. Determine the target oiling rate based on the fiber type. Let the target oiling rate be ω. The oiling rate refers to the percentage of oil agent mass to the mass of a single fiber (ω is commonly set to 0.3%~0.8% for polyester / nylon monofilaments).

[0031] Step S2: Measure the wire feeding speed of the texturing machine's traction roller. The wire feeding speed is set as V (unit: m / min).

[0032] Step S3: Calculate the amount of oil applied at the position of the oiler (1), and set the amount of oil applied as Q (unit: g / min).

[0033] First, the formula for calculating the mass of a single fiber per unit time is:

[0034]

[0035] Secondly, the mass of oil required per unit time for a single fiber is:

[0036]

[0037] Therefore, the final formula for calculating the amount of oil applied in step S3 is:

[0038]

[0039] Example:

[0040] A 20-denier polyester monofilament, with an oiling rate set at 0.5%, a machine speed of 800 m / min, and an oiling amount controlled at:

[0041]

[0042] Density of the spring-loaded oil, ρ The theoretical volumetric flow rate of the oil-adding agent is 1 g / mL (using simplified calculation methods common in the industry):

[0043]

[0044] Considering a 5%-8% loss during actual use, the actual flow rate (assuming a 7% loss) is:

[0045]

[0046] This invention addresses the need for uniform oiling by designing a novel oiler 1 structure. Furthermore, it incorporates an oiling quantity control method for the oiler 1, allowing for controllable adjustment of the oiling quantity based on the fiber speed and fiber type. This solves the problem of insufficient or excessive oiling. The application of this invention effectively addresses workshop production needs and contributes to stabilizing fiber production quality.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
