Description

Technical Field

[0001] The utility model relates to the technical field of chemical fiber spinning, in particular to an oil nozzle rod assembly used on a bulked filament machine frame. Background Art

[0002] Bulk Continuous Filament (BCF) spinning is based on the principle of plastic deformation of synthetic fibers by heat, so that the stretched straight filament bundles are transformed into fluffy curly filament bundles under mechanical and thermal effects. It is widely used in carpet making, clothing manufacturing, and decoration manufacturing. In the BCF spinning process, oiling is an important process in BCF spinning production. Through oiling, the spinning oil agent makes the BCF filament bundles have a certain softness and smoothness. The BCF filament bundles after oiling can prevent the generation of lint and static electricity, reduce broken wires, and facilitate subsequent use. Among various types of spinning oiling, the BCF spinning oiling process is different from other spinning oiling processes. The location of the process is generally set on the frame, and oiling is done through the oil nozzle rod assembly to meet the quality requirements of the BCF spinning process.

[0003] The existing nozzle rod assembly structure usually uses high-strength glue to stick the nozzle and the nozzle rod together, which cannot be separated. For different spinning varieties, a large number of nozzle and nozzle rod bonding assemblies are often required, resulting in increased costs. The nozzle rod assembly is placed for too long and needs to be cleaned and maintained before use, which wastes manpower. In the oiling process, for ease of operation, the nozzle rod assembly is generally set in a position that the operator can reach with his hands. In the existing assembly structure, the nozzle is generally directly exposed. When the operator performs normal production and maintenance operations, the tools held will inevitably come into contact with the nozzle, causing the nozzle to be damaged, and then the entire nozzle rod assembly will be scrapped.

In the description of the utility model, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limitations on the utility model.

[0035] like Figure 1 As shown, an oil nozzle rod assembly for an expanded filament machine frame according to an embodiment of the utility model is used for oiling the expanded filament 7, and includes a mounting seat 1, a mounting rod 2, a pipe joint 3, an oil nozzle 4, and a sheath 5. The mounting rod 2 is inserted into the mounting seat 1, and the mounting rod 2 includes a first end 21 and a second end 22, the pipe joint 3 is inserted into the first end 21 of the mounting rod 2, the oil nozzle 4 is inserted into the second end 22 of the pipe joint 3, and the sheath 5 is sleeved on the outer periphery of the second end 22.

[0036] like Figures 2 to 4 As shown, the nozzle rod assembly also includes a washer 6, which is passed through the outer periphery of the nozzle 4, and one end of the washer abuts against the end face of the second end 22, and the other end abuts against the inner end face of the sleeve 5. The washer 6 is deformed under the extrusion of the sleeve 5 and the second end 22 to generate a clamping force on the nozzle 4.

[0037] Further references Figure 2 In this embodiment, the gasket 6 is made of rubber and is installed with the oil nozzle 4 by interference fit. The pipe joint 3 includes a threaded end 32 and an oil port end 31. The first end 21 and the threaded end 32 are provided with mutually matching threads. The threaded end 32 is connected to the first end 21 by threads. The oil port end 31 is a standard model and can be directly connected to the oil pipe adapted to the oil supply device.

[0038] Further references Figure 3The mounting seat 1 is provided with a mounting hole 104, and a first screw hole 105 is also provided on the side where the mounting hole 104 is located. The first screw hole 105 is tapped with a thread. The mounting rod 2 is inserted into the mounting hole 104, and the mounting seat 1 also includes a first part 101 and a second part 102. One end of the first part 101 is integrally formed with one end of the second part 102, and a slot 103 is formed between the other end of the first part 101 and the other end of the second part 102, and the other end of the first part 101 and the other end of the second part 102 are fixedly connected by a fastening screw 11. In this embodiment, after the mounting rod 2 is inserted into the mounting hole 104, the fastening screw 11 located in the first screw hole 105 is tightened, and the mounting seat 1 is deformed by force, so that the first part 101 and the second part 102 located on both sides of the slot 103 are close to each other, thereby clamping and fixing the mounting rod 2. Preferably, the slot 103 is arranged obliquely relative to the side of the mounting seat 1, and forms an acute angle with the axis of the mounting rod 2, so that the mounting rod 2 can be clamped by rotating the fastening screw 11 a few times, and the slot 103 can also be arranged perpendicular to the axis of the mounting rod 2. Furthermore, the bottom surface of the mounting seat 1 is also provided with a second screw hole 106, and the mounting seat 1 is fixed to the frame by screws passing through the second screw hole 106.

[0039] Further references Figure 4 The sheath 5 includes a connecting portion 51 and a supporting portion 52. The connecting portion 51 is connected to the second end portion 22 by a thread. The outer surface of the connecting portion 51 is provided with anti-slip grooves 511. The supporting portion 52 wraps the exposed part of the oil nozzle 4 to protect the oil nozzle 4. The oil nozzle 4 includes a head 40. The supporting portion 52 is also provided with an avoidance groove 521 so that the head 40 is exposed to the outside air, thereby ensuring that the expanded filament 7 can pass through the oil nozzle 4 smoothly.

[0040] In this embodiment, the materials of the mounting rod 2 and the sheath 5 are both SUS304 stainless steel, and the connecting portion 51 and the second end portion 22 are both provided with threads, and the two are connected by threads. Furthermore, during installation, when the sheath 5 is continuously tightened, the washer 6 is continuously squeezed by the second end portion 22 of the mounting rod 2 and the sheath 5 and deforms, thereby clamping the oil nozzle 4 to prevent it from freely moving along the axis, and at the same time completing the sealing and pressure resistance of the joint between the oil nozzle 4 and the second end portion 22, preventing oil leakage from causing waste and environmental pollution.

[0041] like Figures 5 to 7As shown, the mounting rod 2 is provided with a first mounting groove 24, a second mounting groove 25 and a connecting hole 23, the first mounting groove 24 and the second mounting groove 25 are connected through the connecting hole 23, the pipe joint 3 is installed in the first mounting groove 24, the nozzle 4 is installed in the second mounting groove 25, the pipe joint 3 is provided with a second oil circuit 33, and the first oil circuit 42 is connected with the second oil circuit 33 through the connecting hole 23. A wire guide groove 41 is provided at the head 40 of the nozzle 4, through which the expanded filament 7 can pass, an oil outlet 411 is provided at the bottom of the wire guide groove 41, and a first oil circuit 42 is also provided inside the nozzle 4, and the first oil circuit 42 is connected with the oil outlet 411. When the oil enters the nozzle rod assembly from the pipe joint 3, it passes through the second oil circuit 33, the connecting hole 23 and the first oil circuit 42 in sequence along the direction of arrow A in the figure, and finally flows out from the oil outlet 411.

[0042] In this embodiment, the nozzle model is SY series, the wire guide groove 41 is "V-shaped", and the oil outlet 411 is located at the bottom of the "V-shape". After the sheath 5 is tightened, the support part 52 can wrap most of the nozzle 4 to avoid damage to the nozzle 4 caused by collisions caused by operating errors of the staff, thereby extending the service life of the nozzle 4. Furthermore, when the sheath 5 is tightened, the groove 521 on the support part 52 is exactly opposite to the wire guide groove 41, so that the expanded filament 7 can pass through the wire guide groove 41 smoothly.

[0043] When the nozzle rod assembly for the expanded filament machine frame is used, the nozzle rod assembly only needs to be fixed to the frame through the screw and the second screw hole 106, and then the oil supply device is connected to the oil port end 31 on the pipe joint 3 to complete the installation. Figure 7 As shown, when the expanded filament 7 passes through the guide groove 41, the oil in the oil pipe flows along the direction A in the figure, and the oiling process of the expanded filament 7 is completed at the oil outlet 411. When the oil nozzle needs to be replaced due to production or maintenance, the staff only needs to unscrew the sheath 5 to remove the oil nozzle 4 for replacement or cleaning. The operation is convenient and there is no need to prepare multiple sets of oil nozzle rod assemblies, which can greatly save costs.

[0044] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
