Description

Technical Field

[0001] This utility model belongs to the field of textile equipment technology, and in particular relates to an oiling device for a false twist texturer. Background Technology

[0002] False twist texturing is a process that uses heat to twist and cool to untwist yarns to create elastic "textured elastic yarns". In this process, the oil tank device in the false twist texturing machine plays a crucial role in applying oil to the yarn. Its functions include improving fiber bundles, enhancing smoothness, and improving antistatic properties, thereby ensuring that the finished yarn meets the requirements of subsequent weaving processes.

[0003] Existing technologies generally employ a three-stage layered oil supply structure, with independent small oil tanks installed at the upper, middle, and lower oil tank connections of the false twisting machine. Each small oil tank, using the principle of communicating vessels, relies on atmospheric pressure to progressively deliver oil from the tail to the corresponding oil tank connection. Specifically, after flowing out of the main oil tank at the tail, the oil must sequentially flow through the small oil tanks and oil tank connections of each section before finally reaching the end of the head. This oil circuit design has the following technical drawbacks in practical applications: Significantly long start-up time: Due to the total length of the oil circuit reaching 15-16 sections (approximately 30-40 meters), startup requires waiting for the oil to fill all the oil tanks, a process that typically takes 4-6 hours, severely impacting equipment startup efficiency; Temperature sensitivity: When the ambient temperature is below 15℃, the oil viscosity increases significantly, causing the oil flow rate to decrease by more than 60%. At this time, the oil trough joint near the oil tank at the tail of the machine is prone to overflow (oil flow rate > 0.8m / s), while the oil trough at the far end of the machine head experiences oil supply delay due to insufficient end pressure (< 0.05MPa); oil film uniformity is out of control: experimental data shows that when using the traditional oil supply method on the 16-section machine model, the oil level difference between the oil troughs at the tail and head can reach 12-15cm, directly causing the oil quantity difference rate on the yarn to exceed ±8%, which seriously affects the consistency of the finished yarn quality.

[0004] Especially with the textile industry's increasing demands for equipment capacity, false-twist texturing machines are being upgraded towards higher number of sections (15-16 sections) and longer strokes. Traditional cascade oil supply methods have revealed technical bottlenecks such as severe oil pressure attenuation (up to 75% pressure loss at the end) and delayed oil distribution response. Although existing technologies attempt to improve fluidity by adding auxiliary oil pumps or heating devices, these solutions not only increase energy consumption (additional power consumption ≥1.5kW) but also increase equipment structural complexity by more than 30%, contradicting the trend towards intensive and modular development of textile equipment. Therefore, there is an urgent need to develop a new oil supply system that enables rapid start-up, resists temperature fluctuations, and adapts to machines with longer strokes. Utility Model Content

[0005] In view of this, the present invention proposes an oiling device for a false twist texturing machine. The device has two oil outlets respectively set below the small oil tank. The oil outlets are connected to oil pipes to supply oil to the uppermost oil tank assembly of the tail and head of the machine. The oil outlet of the uppermost oil tank assembly is connected to the oil inlet of the next layer by an oil pipe. A disc handle ball valve is set on the oil pipe to control the flow rate to each layer.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] An oiling device for a false-twist texturing machine includes a frame, an oil trough assembly, a small oil tank, an oil pump motor, and a large oil tank. The oil trough assembly has an oil inlet and an oil outlet at both ends. Several oil trough assemblies are arranged longitudinally to form an oil trough segment, and several oil trough segments are arranged transversely to form an oil trough working surface. Adjacent oil trough segments are located between oil trough assemblies on the same layer. The oil inlets and outlets are connected. Specifically, the oil inlets of two oil trough assemblies are connected to each other via oil pipes, and the oil outlets are connected to each other via oil pipes. The oil trough working surface is set on the machine... The oil pump motor is mounted on a large oil tank. A small oil tank is connected to the oil pump motor via an oil pipe. The lower part of the small oil tank is provided with an oil outlet 1 and an oil outlet 2. The oil outlet 2 is connected to the oil inlet of the upper oil tank component of the first oil tank section via an oil inlet pipe. The oil outlet 1 is connected to the oil inlet of the upper oil tank component of the tail oil tank section via an oil inlet pipe. The oil tank sections are provided with a structure in which the oil outlet of the upper oil tank component is connected to the oil inlet of the lower oil tank component at intervals or continuously. The oil outlet of the bottom oil tank component of the oil tank section is connected to the large oil tank via a return oil pipe.

[0008] The setting of oil outlet one and oil outlet two can realize oil supply from the head and tail oil tank connection respectively, quickly realize oil supply to the whole machine, and at the same time reduce the phenomenon that the oil in the tail oil tank has overflowed while the head oil tank has insufficient oil supply due to the high viscosity of the oil and the long oil circuit.

[0009] In a structure that optimizes the aforementioned scheme, an oil pipe is provided for every two sets of oil tank sections to connect the oil inlet of the upper oil tank assembly to the oil inlet pipe.

[0010] In a structure that optimizes the aforementioned solution, the small oil tank is mounted on an adjustable bracket with a long slot. The adjustable bracket can be adjusted vertically via the slot, thereby speeding up or slowing down the oiling process. Simultaneously, based on the principle of communicating vessels, adjusting the adjustable bracket adjusts the height of the oil level in the small oil tank relative to the ground, controlling the oil level in the uppermost oil tank assembly.

[0011] In a structure that optimizes the aforementioned solution, an overflow pipe is installed inside the small oil tank and connected to the large oil tank. When the liquid level exceeds the height of the overflow pipe opening, the oil will flow back to the large oil tank through the overflow pipe, preventing the oil from overflowing from the small oil tank.

[0012] In a structure that optimizes the aforementioned solution, the oil pump motor is mounted on a large oil tank, and an oil suction pipe is installed on the oil pump motor, with a filter screen installed on the suction pipe. The filter screen can filter out impurities such as waste yarn in the oil, preventing damage to the oil pump.

[0013] In a structure that optimizes the aforementioned scheme, an oil pipe is installed between every two sets of oil tank sections to connect the oil outlet of the lowest oil tank assembly to the return oil pipe. Excess oil flows back to the large oil tank through the return oil pipe after one circulation.

[0014] In a structure that optimizes the aforementioned solution, there are two sets of small oil tanks, and the oil pipes are connected to the oil pump motor via T-shaped tees. The two sets of small oil tanks supply oil to the working surfaces of the oil tanks on both sides of the frame.

[0015] In a structure that optimizes the aforementioned solution, disc handle ball valves are installed on the oil pipes connecting the two sets of small oil tanks via the T-type tee, and on the oil pipes connecting the oil inlet of the oil trough assembly. The disc handle ball valves can adjust the oil flow rate. They require little space to open and close, making them easy to operate and particularly suitable for installation environments with limited space. The working surfaces of the oil troughs on both sides of the frame are surface A and surface B, respectively, each supplied with oil through a small oil tank. When only one side is in production, the oil supply can be stopped by closing one of the disc handle ball valves, reducing oil waste.

[0016] Preferably, the oil pipe is made of PVC braided flexible hose, which can effectively prevent the oil line from collapsing. The small oil tank, large oil tank, and T-shaped tee are all made of stainless steel. The oil tank connector is made of 6063 stainless steel. The adjusting bracket is made of Q235A stainless steel.

[0017] Compared with the prior art, the oiling device for the false twisting texturing machine described in this utility model has the following advantages:

[0018] 1. The equipment achieves a significant improvement in start-up efficiency. Through the dual-outlet bidirectional synchronous oil supply design, the traditional series oil circuit is transformed into a parallel oil supply mode at the head and tail of the machine, greatly shortening the oil delivery path.

[0019] 2. Breakthrough in resistance to temperature fluctuations. Adopting a layered independent oil supply structure, coupled with a disc-handle ball valve for flow regulation, it effectively maintains a low oil tank pressure differential in low-temperature environments, ensuring stable oil flow rate and resolving overflow and oil supply delay issues caused by temperature sensitivity.

[0020] 3. Oil film uniformity is precisely controlled. Through the synergistic effect of the adjustable support and overflow oil pipe, dynamic balance of the oil level in the oil tank is achieved, reducing the oil content difference rate on the yarn and improving the consistency of finished product quality.

[0021] 4. Significant energy and space optimization effects. In terms of energy-saving design, eliminating the auxiliary oil pump reduces additional system power consumption. Combined with T-type three-way branch oil supply, closing the non-working side valve during single-sided production reduces oil consumption. Regarding space efficiency, the 90° opening and closing structure of the disc handle ball valve reduces the required valve operating space, and the modular oil tank section layout reduces the horizontal space occupied by the equipment.

[0022] 5. System reliability is comprehensively improved. The dual protection design of the overflow oil pipe and filter screen reduces the incidence of oil circuit blockage. The adjustable bracket has a certain height adjustment range and can adaptively compensate for pressure fluctuations caused by changes in oil viscosity, ensuring stability during long-term operation.

[0036] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] like Figure 1 As shown, the oiling device of the false twisting deformation machine in this embodiment is mainly composed of a frame 1, an oil tank assembly 2, a small oil tank 6, an oil pump motor 8, a large oil tank 9, and other components.

[0038] The frame 1 serves as the supporting structure for the entire device, and an oil tank working surface is provided on it. The oil tank working surface is formed by several oil tank segments arranged horizontally, and each oil tank segment is composed of several oil tank connecting parts 2 arranged vertically. Each oil tank connecting part 2 has an oil inlet 21 and an oil outlet 22 at both ends. Adjacent oil tank segments are located between oil tank connecting parts 2 on the same layer, and the oil inlet 21 and oil outlet 22 are connected by corresponding oil pipes to achieve oil flow between the oil tank connecting parts on the same layer. For specific connection details, please refer to [reference needed]. Figure 2 As shown.

[0039] The small oil tank 6 is connected to the oil pump motor 8 installed on the large oil tank 9 via an oil pipe. The lower part of the small oil tank 6 is provided with an oil outlet 1 61 and an oil outlet 2 62. The oil outlet 2 62 is connected to the oil inlet 21 of the upper oil tank assembly 2 of the first oil tank section via an oil inlet pipe. The oil outlet 1 61 is connected to the oil inlet 21 of the upper oil tank assembly 2 of the tail oil tank section via an oil inlet pipe. This dual oil outlet design realizes bidirectional synchronous oil supply to the oil tank assembly from both the head and tail of the machine.

[0040] Between the oil tank sections, there are intervals where the oil outlet 22 of the upper layer of oil tank connector 2 is connected to the oil inlet 21 of the lower layer of oil tank connector 2, allowing the oil to flow orderly between the different layers of oil tank connectors. The oil outlet 22 of the bottom layer of oil tank connector 2 is connected to the large oil tank 9 through a return oil pipe to complete the oil circulation. Detailed structure of the return oil point can be found in [reference needed]. Figure 3 As shown.

[0041] The small oil tank 6 is mounted on an adjustable bracket 3. The adjustable bracket 3 has a long slot 31, through which it can be adjusted up and down, thereby adjusting the height of the oil level in the small oil tank 6 relative to the ground and controlling the oil level in the uppermost oil tank assembly. An overflow pipe 63 is installed inside the small oil tank 6, connected to the large oil tank 9 to prevent oil from overflowing from the small oil tank 6. The cross-sectional structure of the small oil tank 6 is as follows... Figure 6 As shown.

[0042] The oil pump motor 8 is equipped with an oil suction pipe 81, and a filter screen 82 is installed on the oil suction pipe 81 to filter impurities in the oil and protect the oil pump motor 8. The structure of the oil pump motor 8 is as follows. Figure 5 As shown.

[0043] Regarding the oil circuit connections, an oil pipe is installed between every two sets of oil tank sections to connect the oil inlet 21 of the upper oil tank connector 2 to the oil inlet pipe. Simultaneously, an oil pipe is installed between every two sets of oil tank sections to connect the oil outlet 22 of the lowermost oil tank connector 2 to the return oil pipe. There are two sets of small oil tanks 6, with oil pipes connected to the oil pump motor 8 via T-shaped tees 5, supplying oil to the working surfaces of the oil tanks on both sides of the frame 1. Disc handle ball valves 4 are installed on the oil pipes connecting the two sets of small oil tanks 6 via T-shaped tees 5 and on the oil pipes connecting the oil inlet 21 of the oil tank connector 2. These valves are used to adjust the oil flow rate, and require minimal space to open and close, making operation convenient. The cross-sectional structure of the oil tank connector 2 shows the internal structure of the part in contact with the oil, such as... Figure 4 As shown.

[0044] In addition, the oil pipes are made of PVC braided hoses, which can effectively prevent the oil lines from collapsing. The small oil tank 6, the large oil tank 9, and the T-shaped tee 5 are all made of stainless steel, the oil tank connector 2 is made of 6063 material, and the adjusting bracket 3 is made of Q235A material, ensuring the durability and stability of the device.

[0045] Device operation process:

[0046] When the equipment is turned on, the oil pump motor 8 is powered on and begins to work. The oil pump motor 8, installed on the large oil tank 9, has a filter 82 on its suction pipe 81 that filters out impurities such as waste yarn from the oil, ensuring clean oil is drawn in from the large oil tank 9. The oil outlet of the oil pump motor 8 is divided into two oil circuits via a T-shaped tee 5, each connected to a disc handle ball valve 4 and then to two smaller oil tanks 6. The disc handle ball valve 4 allows for flexible adjustment of the oil inlet flow to meet different operating conditions.

[0047] The small oil tank 6 is mounted on an adjustable bracket 3, which has a long slot 31, allowing operators to adjust its height. Based on the principle of communicating vessels, changing the height of the adjustable bracket 3 adjusts the oil level in the small oil tank 6 relative to the ground, thus precisely controlling the oil level in the uppermost oil tank assembly 2. The small oil tank 6 has two outlets, a first outlet 61 and a second outlet 62, each connected to an oil pipe, supplying oil to the uppermost oil tank assembly 2 from the machine head and tail respectively. This significantly shortens the oil transport path and improves equipment startup efficiency. Simultaneously, the small oil tank 6 has an overflow pipe 63. When the oil level in the small oil tank 6 exceeds the height of the overflow pipe 63, the oil flows back to the large oil tank 9 through the overflow pipe 63, effectively preventing oil from overflowing from the small oil tank 6.

[0048] The oil outlet 22 of the uppermost oil tank assembly 2 is connected to the oil inlet 21 of the lower oil tank assembly 2 via an oil pipe. Each oil pipe connecting the oil outlet of the upper oil tank assembly 2 and the oil inlet of the lower oil tank assembly 2 is equipped with a disc handle ball valve 4, which can precisely control the oil flow rate. When the liquid level in the upper oil tank assembly 2 reaches the set height, the oil flows into the lower oil tank assembly 2 through the oil outlet 22 and the oil pipe under the action of gravity. In this way, oil is supplied to the three oil tank assemblies 2 from top to bottom.

[0049] Once the oil in the lowest oil tank assembly 2 reaches the set height, any excess oil is collected through its outlet 22 into the return oil pipeline and eventually flows back to the large oil tank 9, completing the entire oil circulation process. During this process, an oil pipe is installed between every two oil tank sections to connect the oil inlet 21 of the upper oil tank assembly 2 to the oil inlet pipe, and simultaneously, an oil pipe is installed between every two oil tank sections to connect the oil outlet 22 of the lowest oil tank assembly 2 to the return oil pipeline, ensuring the orderly flow and circulation of oil throughout the entire oil supply device.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
