Description

Technical Field

[0001] This application relates to the field of textile equipment technology, specifically to a device for uniformly applying oil to a POY to DTY oiling roller. Background Technology

[0002] POY raw yarn is stretched and false-twisted by a texturing machine to form DTY tow. Oiling is the final process in DTY tow production, directly determining the tow's antistatic properties, weaving smoothness, and finished product quality. Current technologies commonly use spraying and ceramic scraping modules to achieve uniform oiling. The scraped oil generally falls into a collection tank below due to gravity. However, because the oil has poor fluidity, the oil removal speed is slow in the contact area between the DTY tow and the ceramic scraping module, easily leading to oil accumulation. This accumulated oil will then flow back onto the high-speed moving DTY tow, affecting the overall uniformity of oiling. Summary of the Invention

[0003] The main purpose of this application is to provide a POY to DTY oiling roller uniform oiling device, which aims to solve the defect of uneven oiling in the prior art.

[0015] Optionally, the outer circumferential surface of the rotating roller is provided with several sets of oil extraction holes with identical structures, and each oil extraction hole is connected to the negative pressure chamber; each oil extraction hole in the same set is arranged around the axis of the rotating roller, and each set of oil extraction holes is arranged along the axial direction of the rotating roller.

[0016] Optionally, the adsorption and accumulation module includes an annular base. Around the axis of the annular base, a plurality of filling cavities are provided on the annular base. Each filling cavity is provided with an accumulation block made of needle-punched cotton cloth, and any two adjacent accumulation blocks are tightly fitted together.

[0017] Optionally, the adsorption and accumulation module further includes a ring-shaped support block, which is fitted onto the surface of the accumulation block. Along the radial direction of the ring base, the outer surface of the accumulation block and the inner surface of the support block are in close contact. The support block is made of semi-rigid foam plastic. The support block has an open capillary structure, and the pore diameter of the accumulation block is larger than that of the support block, so as to form a capillary pressure difference between the two layers.

[0018] Optionally, the outer surface of the support block is provided with a plurality of axial flow guide grooves and a plurality of circumferential flow guide grooves. The axial flow guide grooves are arranged sequentially around the axis of the support block, and the circumferential flow guide grooves are arranged sequentially along the axis of the support block, with each circumferential flow guide groove connecting the axial flow guide grooves.

[0021] Compared with the prior art, this application has the following beneficial effects:

[0022] This application includes a frame, on which an oiling tank and a support frame are mounted. An oil removal roller assembly is mounted on the support frame. The oil removal roller assembly also has a negative pressure chamber. The inlet end of the negative pressure chamber is connected to an external high-pressure air source via a rotary joint, and the outlet end of the negative pressure chamber is connected to an exhaust pipe, which is connected to a recovery box. Simultaneously, along the airflow direction, a plurality of oil extraction holes are provided on the outer circumferential surface of the oil removal roller assembly, each of which communicates with the negative pressure chamber. An adsorption and accumulation module is also fitted onto the outer surface of the oil removal roller assembly. An oil removal sleeve is fitted onto the surface of the adsorption and accumulation module, and a ceramic oil scraping layer is provided on the surface of the oil removal sleeve. The oil removal sleeve also has a plurality of oil leakage holes, each of which connects the ceramic oil scraping layer to the adsorption and accumulation module. The adsorption and accumulation module has an open capillary structure.

[0023] During use, the DTY filaments to be coated with oil are coated in the oiling tank. Then, the DTY filaments pass through the oil removal roller assembly. The oil removal sleeve on the oil removal roller assembly scrapes off the excess oil layer on the DTY filaments. The scraped oil flows into the oil drain hole under its own gravity and continues to penetrate into the adsorption and accumulation module. Because the adsorption and accumulation module is equipped with an open capillary structure, the oil will continuously seep into the adsorption and accumulation module under the action of capillary pressure to temporarily preserve the oil.

[0024] Then, high-pressure gas (such as nitrogen or air) generated by an external high-pressure gas source is introduced into the negative pressure chamber. The high-pressure gas is discharged directly from the exhaust pipe. At this time, a material suction negative pressure will be formed in the negative pressure chamber, and it will act directly on the adsorption and accumulation module through the oil suction hole, thereby extracting the oil stored in it and discharging it from the exhaust pipe with the high-pressure gas. Finally, the oil is recovered and reused in the recovery box.

[0025] Compared with the prior art, this application can quickly guide the scraped oil to the area where the adsorption and accumulation module is located through the oil leakage hole, and then quickly guide the oil into the interior of the adsorption and accumulation module for temporary storage through capillary pressure; while inside the oil removal roller, a negative pressure is formed by the negative pressure chamber and high-pressure air, thereby forcibly extracting the oil from the adsorption and accumulation module. The entire device is in a dynamic equilibrium state of scraping and discharging oil at the same time, and the amount of residual oil on the surface of the entire oil removal sleeve is always within a suitable range. Therefore, the oiling device described in this application can avoid the accumulation of a large amount of oil in the oil removal sleeve and prevent the oil from flowing back into the DTY filament bundle, thereby improving the uniformity of oiling.

[0026] During use, the adsorption and storage module can not only adsorb and store excess oil, but also adsorb lint and chemical fiber impurities discharged with the oil, thus filtering the oil and preventing a large number of impurities from entering the oil, reducing the difficulty of oil recovery and treatment, thereby improving the quality of recovered oil and reducing the operating cost of the equipment.

[0027] Finally, the adsorption and accumulation module can also isolate the airflow in the negative pressure chamber, preventing the negative pressure formed in the negative pressure chamber from flowing into the DTY filaments through the oil leakage hole, ensuring the stability of the DTY filaments during the oil removal process, preventing them from jumping and scraping against the oil removal sleeve, and improving the quality of the DTY filaments.

[0041] Implementation Method 1

[0042] Reference Figures 1 to 7 This embodiment, as an optional embodiment of this application, discloses a POY to DTY oiling roller uniform oiling device, including a frame 1 and an oiling tank 2, wherein the oiling tank 2 is installed on the frame 1; the oiling tank 2 includes a box body 201 and a sealing cover 202, the box body 201 is generally arranged in a cuboid structure, the sealing cover 202 is sealed to the box body 201, and along the length direction of the sealing cover 202, a feed hole 203 is provided at one end of the sealing cover 202, and a discharge hole 204 is provided at the other end;

[0043] Meanwhile, several guide wheels 205 are provided inside the housing 201 to guide the movement of the DTY filament bundle and adjust the running path of the DTY filament bundle in the oiling tank 2.

[0044] Two lifting rods 206 are also provided on the sealing cover 202. Along the length of the sealing cover 202, the two lifting rods 206 are respectively provided at both ends of the sealing cover 202 and respectively correspond to the feed hole 203 and the discharge hole 204. Each lifting rod 206 is provided with a locking screw, and tensioning wheels 207 are also provided on the two lifting rods 206.

[0045] The position of the tensioning wheel 207 can be adjusted by adjusting the height of the two lifting rods 206, thereby controlling the tension of the DTY filament bundle; at the same time, an oil spray nozzle 208 for spraying oil is also provided in the housing.

[0046] Furthermore, a support frame 3 is also provided on the frame 1. The support frame 3 is located at the discharge end of the oiling box 2 to receive the DTY filament bundles after the oiling operation is completed.

[0047] The support frame 3 adopts a portal frame structure design. An oil removal roller assembly 4 is provided on the support frame 3. The oil removal roller assembly 4 includes two sets of identical oiling rollers 401. The two oiling rollers 401 are symmetrically arranged vertically on the support frame 3 along the height direction of the support frame 3.

[0048] Furthermore, the oiling roller 401 includes a rotating roller 402. Along the axial direction of the rotating roller 402, rolling bearings are provided at both ends of the rotating roller 402. The rotating roller 402 is rotatably connected to the support frame 3 through the two rolling bearings.

[0049] The rotating roller 402 is also provided with a negative pressure cavity 5. The negative pressure cavity 5 is arranged along the axis of the rotating roller 402. The negative pressure cavity 5 is coaxial with the rotating roller 402 and along the axis of the rotating roller 402. The negative pressure cavity 5 passes through the two end faces of the rotating roller 402.

[0050] Along the axial direction of the rotating roller 402, the two ends of the negative pressure chamber 5 are an air inlet and an air outlet, respectively. The air inlet is connected to an external high-pressure gas source to introduce high-pressure gas into the negative pressure chamber 5; the air outlet of the negative pressure chamber 5 is connected to an exhaust pipe 6.

[0051] Furthermore, a pressure regulating valve and a flow valve are added at the air inlet. The pressure regulating valve and the flow valve control the airflow and velocity entering the negative pressure chamber 5, thereby adjusting the suction negative pressure in the negative pressure chamber 5. That is, when too much oil accumulates, the suction negative pressure is increased by increasing the velocity and flow rate to achieve rapid oil separation. Conversely, the suction negative pressure is reduced to improve the adjustability of the entire device.

[0052] Meanwhile, several oil extraction holes 7 with identical structures are provided on the outer peripheral surface of the rotating roller 402. Along the radial direction of the rotating roller 402, each oil extraction hole 7 connects the outer surface of the rotating roller 402 with the negative pressure chamber 5.

[0053] Each of the oil extraction holes 7 is divided into several groups. Each of the oil extraction holes 7 in the same group is arranged around the axis of the rotating roller 402, that is, evenly arranged along the circular trajectory line. Each group of oil extraction holes 7 is arranged sequentially along the axis of the rotating roller 402 to cover the entire outer surface of the rotating roller 402.

[0054] Furthermore, the oiling device also includes an adsorption and accumulation module 8 and an oil removal sleeve 9. The adsorption and accumulation module 8 includes an annular base 801. Along the axis of the annular base 801, both ends of the annular base 801 are closed by baffles. Around the axis of the annular base 801, the internal space of the annular base 801 is divided into several arc-shaped filling cavities 802, and any two adjacent filling cavities 802 are interconnected.

[0055] Meanwhile, along the radial direction of the annular base 801, both ends of each filling cavity 802 penetrate the inner and outer surfaces of the annular base 801.

[0056] Each of the filling cavities 802 is filled with a storage block 803, which is made of needle-punched cotton cloth; at the same time, around the axis of the annular base 801, any two adjacent storage blocks 803 are tightly fitted together, and along the radial direction of the annular base 801, both ends of each storage block 803 protrude outside the annular base 801.

[0057] The adsorption and accumulation module 8 is fitted on the outer surface of the rotating roller 402, and each accumulation block 803 is in close contact with the outer surface of the rotating roller 402.

[0058] It should be noted that, along the axial direction of the rotating roller 402, any two adjacent rows of oil extraction holes 7 are solid structures. The solid structures correspond to the ribs on the annular base 801 to prevent the annular base 801 from blocking the oil extraction holes 7.

[0059] The accumulation block 803 made of needle-punched cotton cloth can effectively ensure the capillary adsorption of oil, thereby realizing the rapid transfer of oil; while the annular base 801 can ensure that each accumulation block 803 can maintain a stable installation position, thereby ensuring the structural stability of the entire adsorption accumulation module 8.

[0060] Secondly, the annular base 801 can also provide structural support for the entire adsorption and storage module 8, thereby ensuring its structural rigidity, preventing excessive deformation of the storage block 803, and ensuring that the capillary pores on it are always unobstructed.

[0061] Furthermore, the adsorption and accumulation module 8 also includes a support block 804, which is generally arranged in a ring structure. The support block 804 is fitted onto the surface of the accumulation block 803, that is, along the radial direction of the annular base 801, the outer surface of the accumulation block 803 is in close contact with the inner surface of the support block 804. The support block is made of semi-rigid foam plastic. The support block has an open capillary structure, and the pore diameter of the accumulation block is larger than the pore diameter of the support block, so as to form a capillary pressure difference between the two layers.

[0062] In the above technical solution, the support block can further isolate the accumulation block, ensuring its structural stability, and at the same time provide support for the subsequent oil removal sleeve, ensuring that the gap between it and the DTY filament bundle is in a relatively stable state. On the other hand, the support block also has an open capillary structure, which forms a capillary pressure difference with the accumulation block, thereby guiding the oil to flow towards the accumulation block side. At the same time, the support block can also further isolate the negative pressure in the negative pressure chamber, ensuring the stability of the DTY filament bundle.

[0063] Furthermore, the degreasing sleeve 9 is provided with a plurality of mousse grooves 901, and each mousse groove 901 has a ceramic oil scraping layer 10 on its inner surface. Each mousse groove 901 is arranged sequentially along the axial direction of the degreasing sleeve 9 to achieve synchronous oil scraping operation of multiple DTY filament bundles.

[0064] Meanwhile, several oil leakage holes are provided at the bottom of each mousse groove. Each oil leakage hole is only provided in the upper half of the oil removal sleeve and is evenly arranged around the axis of the mousse groove.

[0065] The degreasing sleeve 9 is placed on the adsorption and accumulation module 8, that is, the inner surface of the degreasing sleeve 9 is in close contact with the outer surface of the adsorption and accumulation module 8.

[0066] It should be noted that there is a certain gap between the degreasing sleeve 9 and the DTY filament bundle to prevent the DTY filament bundle from being scratched by the degreasing sleeve and to ensure the quality of the DTY filament bundle.

[0067] In the above structure, when the DTY filament bundle passes through the mousse groove, the degreasing sleeve 9 scrapes off the excess oil on the surface of the DTY filament bundle. Part of the scraped oil directly enters the oil leakage hole located at the high point of the mousse groove, while part of the oil flows along the bottom surface of the mousse groove under its own gravity. Since the entire degreasing sleeve is a ring structure, the mousse groove liquid is also a ring structure, which can ensure that the flowing oil is quickly separated from the DTY filament bundle. Thus, even when the oil is discharged, the oil and DTY filament bundle are separated as quickly as possible.

[0068] Furthermore, the outlet end of the exhaust pipe 6 is also connected to a recycling box 12. The recycling box 12 is generally arranged in a cuboid structure. Along the length of the recycling box 12, one end of the recycling box 12 is provided with an air inlet 1201 and the other end is provided with an exhaust port 1202. The air inlet 1201 is connected to the exhaust pipe 6. The exhaust port 1202 is open and is provided with a filter module or filter screen 1205.

[0069] At the bottom of the recycling bin 12, there is also a cone-shaped oil collection hood 1203, and the outlet end of the oil collection hood 1203 is connected to the oil collection tank 1204 through a pipeline.

[0070] Along the direction from the air inlet 1201 to the exhaust outlet 1202, a plurality of filter screens 1205 are sequentially arranged in the recovery box 12; the air inlet 1201 is directly opposite the filter screens 1205.

[0071] When the oil-gas mixture enters the recovery tank 12, the velocity of the oil-gas mixture will decrease due to the increased volume of the recovery tank 12. At this time, some of the heavier oil droplets will fall off under their own gravity and adhere to the oil collection hood 1203, and finally flow into the oil collection tank 1204.

[0072] Some of the lighter oil droplets will continue to move along the length of the recovery box 12 and eventually collide with and adhere to the filter screen 1205. Through the layer-by-layer adsorption of the multi-stage filter screen 1205, the oil-gas mixture is effectively separated. The separated oil droplets will continuously gather under the action of gravity and eventually enter the oil collection box 1204.

[0073] Furthermore, the outer surface of the last or several stages of the filter screen 1205 can be made of cotton cloth or plastic film. By using the above materials, the air permeability of the filter screen 1205 can be reduced to the maximum extent, so as to achieve complete interception of residual oil droplets. The airflow can be discharged from the exhaust port 1202 under the impetus of the subsequent incoming airflow, thereby improving the adsorption effect of oil droplets.

[0074] It should be noted that in addition to the effect of layer-by-layer interception, the multi-layer filter 1205 can also effectively reduce the airflow velocity. On the one hand, it prevents the gas from carrying oil and gas out of the exhaust port 1202, and on the other hand, it creates conditions for the natural fall of heavier oil droplets, thus ensuring the quality of oil-gas separation.

[0075] When using the device described in this application, the DTY yarn bundle to be coated with oil is first passed through the tensioning wheel and each guide wheel, and then passed between the two oiling rollers. In the oiling tank, the DTY yarn bundle is coated with oil. Then the DTY yarn bundle passes through the mousse groove. The oil removal sleeve scrapes off the excess oil layer on the DTY yarn bundle. Part of the scraped oil enters directly into the oil drain hole located at the high point of the mousse groove, while part of the oil flows along the bottom surface of the mousse groove under its own gravity. Since the mousse groove liquid has a ring structure, it can ensure that the flowing oil is quickly separated from the DTY yarn bundle, thereby ensuring that the oil and DTY yarn bundle are separated as quickly as possible while the oil is being drained.

[0076] The oil flowing through the drain hole will seep into the support block and the accumulation block under the action of capillary pressure;

[0077] Then, the high-pressure gas (such as nitrogen or air) generated by the external high-pressure gas source is regulated by the pressure regulating valve and enters the negative pressure chamber. The high-pressure gas is directly discharged from the exhaust pipe. In the negative pressure chamber, the high-pressure gas passing through quickly will form a suction negative pressure. The suction negative pressure acts directly on the adsorption and accumulation module through the oil extraction hole, thereby extracting the oil accumulated inside and discharging it from the exhaust pipe with the high-pressure gas. Finally, the oil is recovered and reused in the recovery tank.

[0078] Compared with the prior art, this application can quickly guide the scraped oil to the area where the adsorption and accumulation module is located through the oil leakage hole, and then quickly guide the oil into the interior of the adsorption and accumulation module for temporary storage through capillary pressure; while inside the oil removal roller, a negative pressure is formed by the negative pressure chamber and high-pressure air, thereby forcibly extracting the oil from the adsorption and accumulation module. The entire device is in a dynamic equilibrium state of scraping and discharging oil at the same time, and the amount of residual oil on the surface of the entire oil removal sleeve is always within a suitable range. Therefore, the oiling device described in this application can avoid the accumulation of a large amount of oil in the oil removal sleeve and prevent the oil from flowing back into the DTY filament bundle, thereby improving the uniformity of oiling.

[0079] During use, the adsorption and storage module can not only adsorb and store excess oil, but also adsorb lint and chemical fiber impurities discharged with the oil, thus filtering the oil and preventing a large number of impurities from entering the oil, reducing the difficulty of oil recovery and treatment, thereby improving the quality of recovered oil and reducing the operating cost of the equipment.

[0080] Finally, the adsorption and accumulation module can also isolate the airflow in the negative pressure chamber, preventing the negative pressure generated in the chamber from flowing through the oil leakage hole to the DTY filaments. This ensures the stability of the DTY filaments during the degreasing process, preventing them from jumping and scraping against the degreasing sleeve, thus improving the quality of the DTY filaments. The above are merely preferred embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural transformations made based on the description and drawings of this application, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
