Description

Technical Field

[0001] This invention relates to the field of chemical fiber production technology, and in particular to an oiling system for continuous spinning viscose filament spindles. Background Technology

[0002] When chemical fiber manufacturers produce cellulose fiber filaments, the filaments go through four processes: coagulation, washing, oiling, and drying. After the filaments are coagulated and formed, they are washed to remove residual acid and impurities. Then, they are oiled to give the filaments a certain degree of cohesion and antistatic properties, and also to make the filaments smoother and silkier.

[0003] Currently, in the production process of viscose continuous spinning filament, the commonly used oiling method is to use a reducer to drive multiple sets of gear metering pumps. Each set of gear metering pumps delivers the oil from a single oil tank to the combing zone of each section of the continuous spinning machine through 10 to 12 oil pipes. The four filaments arranged from top to bottom in each section are oiled by contacting the oil flowing down from between the teeth of the combing machine (a small amount drips onto the drum, some forming an oil skin, and some sticking to the filaments).

[0004] For example, existing published documents CN108792827A-Oil-Gluing Device for Viscose Filament Winding Equipment and CN216105303U-Oil-Gluing Device for Viscose Filament Winding Equipment both disclose an oiling system for chemical fiber production. Although the existing oiling systems can achieve oiling in the daily production of chemical fibers, they still have the following shortcomings in actual use:

[0005] 1. The amount of oil applied to the four yarns in the same area varies greatly. One oil pipe supplies oil to the comb. When the oil flows down between the teeth of the comb, the yarns come into contact with the flowing oil to achieve the oiling effect. However, due to the current production method, the yarns are not evenly distributed between the combs, and the yarns at the top come into contact with the oil first, so the oiling is more thorough. The amount of oil applied to the bottom yarn will be slightly lower, especially when producing low-sizing products.

[0006] 2. Waste of oil when dealing with broken filaments: When a filament breaks in a certain area, the operator needs to pull out the corresponding oil pipe for that area, and after rewinding it around the oiling area, promptly insert the oil pipe back into its original position. Although this operation can prevent the oil from continuously dripping into the treatment drum when not spinning, the oil output does not stop during the process of dealing with broken filaments, resulting in a certain amount of oil waste and increasing production costs.

[0007] 3. When a wire breaks, the amount of oil on the remaining unbroken spindles changes drastically. When a spindle in a certain area breaks, the oil will spread to the remaining three spindles, causing the amount of oil on the wire to suddenly increase by about 1 / 3. This sudden increase in the amount of oil will cause color difference in the appearance of the wire, and it needs to be completely disposed of as waste wire, causing a certain amount of waste in production.

[0008] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Summary of the Invention

[0009] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0010] In view of the problem that the existing oiling devices for filament production have uneven oiling, which affects the quality of the filament after oiling, a continuous viscose filament single-spindle oiling system is proposed.

[0011] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a continuous spun viscose filament single-spindle oiling system, comprising an oiling mechanism and a control mechanism; the oiling mechanism includes an oil tank, an oil pump, a solenoid valve, an oiler, and a yarn cylinder; the oil tank is connected to the input end of the oil pump, and the output end of the oil pump is connected to the input end of the solenoid valve; the oiler is cylindrical, and four oil inlet grooves are arrayed along the axial direction on the side wall of the oiler, one end of the oil inlet grooves extends to the axis of the oiler, and four oiling grooves are circumferentially arranged on the outer side wall of the oiler, and the four oil inlet grooves and the four oiling grooves are arranged in a one-to-one correspondence; the end of the oil inlet groove near the axis of the oiler is connected to the corresponding oiling groove through an oil outlet hole, and the four oil inlet grooves are connected to the output ends of the four solenoid valves in a one-to-one correspondence.

[0012] The beneficial effects of this invention are as follows: When this oiling system is in use, each filament passes independently through the oiling groove on the oiler. Four solenoid valves independently control the oil to enter the corresponding oiling groove through the oil inlet and outlet. In this way, the filaments are independently oiled after passing through the oiling groove. This setting avoids uneven oiling caused by multiple filaments being arranged side by side and the oil flowing from top to bottom (excessive oiling on the upper filaments and insufficient oiling on the lower filaments). Moreover, if a filament breaks, it will not affect the uniform oiling of other filaments on the same oiler. Overall, it has good practicality and can effectively maintain the production quality of filaments.

[0013] As a preferred embodiment of the continuous spun viscose filament single-spindle oiling system of the present invention, the oil inlet groove is inclined on the same vertical plane, and the end of the oil inlet groove near the axis of the oiler is the inclined lower end.

[0014] As a preferred embodiment of the continuous spun viscose filament single-spindle oiling system of the present invention, the filament passes through the oiling groove along the side wall of the oiler, and one end of the filament is wound around the yarn bobbin. The oiling groove is inclined on the same vertical plane, and the lower inclined end of the oiling groove is the input end of the filament.

[0015] As a preferred embodiment of the continuous spun viscose filament single-spindle oiling system of the present invention, an oil supply pipe is provided between the oil tank and the oil pump, and the two ends of the oil supply pipe are respectively connected to the oil tank and the oil pump through a first connector.

[0016] As a preferred embodiment of the continuous spun viscose filament single-spindle oiling system of the present invention, a first oil delivery pipe is provided between the oil pump and the solenoid valve. One end of the first oil delivery pipe is connected to the oil outlet of the oil pump through a second connector, and the other end of the first oil delivery pipe is connected to the oil inlet pipe on the solenoid valve through a second connector.

[0017] As a preferred embodiment of the continuous spun viscose filament single-spindle oiling system of the present invention, the oil pump includes multiple sets of gear metering pumps driven by a reducer. Each set of gear metering pumps has six layers, each layer corresponds to two oil outlets, and the same oil outlet supplies oil to the same oiler through four solenoid valves.

[0018] As a preferred embodiment of the continuous spun viscose filament single-spindle oiling system of the present invention, a second oil supply pipe is provided between the solenoid valve and the oiler. One end of the second oil supply pipe is connected to the oil outlet pipe on the solenoid valve through a fourth connector, and the other end of the second oil supply pipe is connected to the oiler through a fourth connector.

[0019] Given that existing oiling systems cannot properly handle oil when filament breakage occurs, leading to oil waste and equipment contamination, the present invention provides a further optimized and improved continuous viscose filament single-spindle oiling system. The control mechanism includes a PLC controller and a filament breakage alarm. The filament breakage alarm is installed on the filament between the oiler and the filament drum. A return oil pipe is also provided on the solenoid valve. The PLC controller is electrically connected to the solenoid valve and the filament breakage alarm via conductive lines.

[0020] As a preferred embodiment of the continuous spun viscose filament single-spindle oiling system of the present invention, the oil return pipe is connected to one end of the third oil supply pipe through a third connector, while the other end of the third oil supply pipe is connected to the input end of the oil tank.

[0021] Another beneficial effect of the present invention is that, during use, each filament after being oiled by the oiler is equipped with a filament breakage alarm. When a filament breakage occurs, the alarm will sound an alarm to remind the staff. At the same time, the alarm will transmit the signal to the PLC controller. After receiving the signal, the PLC controller will control the oil outlet pipe of the corresponding solenoid valve to close and the return pipe to open. In this way, the oil entering the solenoid valve will flow to the return pipe and finally return to the oil tank through the third oil delivery pipe, so as to collect the oil and avoid oil waste and pollution of the device itself.

[0035] Example 1

[0036] Reference Figure 1 , Figure 5 and Figure 6 As shown, this is the first embodiment of the present invention. This embodiment provides a continuous spun viscose filament single-spindle oiling system, including an oiling mechanism and a control mechanism. The oiling mechanism is used for free oiling operation of the filament, while the control mechanism is used for alarm and oil recovery after filament breakage.

[0037] Specifically, the oiling mechanism includes an oil tank 1, an oil pump 3, a solenoid valve 6, an oiler 10, and a screw spool 12. The oil tank 1 is connected to the input end of the oil pump 3 to achieve oil transfer between them. Preferably, an oil supply pipe is provided between the oil tank 1 and the oil pump 3, and the two ends of the oil supply pipe are connected to the oil tank 1 and the oil pump 3 respectively through a first connector 2. The output end of the oil pump 3 is connected to the input end of the solenoid valve 6 to achieve oil transfer between them. Preferably, a first oil delivery pipe is provided between the oil pump 3 and the solenoid valve 6. 4. One end of the first oil supply pipe 4 is connected to the oil outlet of the oil pump 3 through the second connector 5, and the other end of the first oil supply pipe 4 is connected to the oil inlet pipe 601 on the solenoid valve 6 through the second connector 5; a second oil supply pipe 9 is provided between the solenoid valve 6 and the oiler 10. One end of the second oil supply pipe 9 is connected to the oil outlet pipe 602 on the solenoid valve 6 through the fourth connector 8, and the other end of the second oil supply pipe 9 is connected to the oiler 10 through the fourth connector 8, so as to realize the oil supply between the solenoid valve 6 and the oiler 101.

[0038] For further details, please see Figure 1 As shown, the oil pump 3 includes multiple gear metering pumps driven by a reducer. Each gear metering pump has six layers, and each layer corresponds to two oil outlets. The same oil outlet supplies oil to the same oiler 10 through four solenoid valves 6, so as to realize the synchronous oil supply of multiple oilers 10 by the oil pump 3.

[0039] See details Figure 1 , Figure 3 and Figure 4As shown, the oiler 10 is cylindrical. Four oil inlet grooves 1001 are arrayed along the axial direction on the side wall of the oiler 10. One end of the oil inlet groove 1001 extends to the axis of the oiler 10. Four oil upper grooves 1002 are circumferentially arranged on the outer side wall of the oiler 10. The four oil inlet grooves 1001 and the four oil upper grooves 1002 are arranged in a one-to-one correspondence. The end of the oil inlet groove 1001 near the axis of the oiler 10 is connected to the corresponding oil upper groove 1002 through the oil outlet hole 1003. The four oil inlet grooves 1001 are connected to the output ends of the four solenoid valves 6 in a one-to-one correspondence. The long wire passes through the oil upper groove 1002 along the side wall of the oiler 10, and one end of the long wire is wound around the wire spool 12.

[0040] When in use, the solenoid valve 6 inputs oil into the oil inlet 1001 of the oiler 101 through the second oil supply pipe 9. The oil that enters is delivered through the oil outlet 1003 and finally discharged from the upper oil tank 1002. As the filament passes through the upper oil tank 1002, the oil in the upper oil tank 1002 will continuously oil the filament.

[0041] For further details, please see Figure 3 and Figure 4 As shown, the oil inlet groove 1001 is inclined on the same vertical plane, and the end of the oil inlet groove 1001 near the axis of the oiler 10 is the inclined lower end. This allows the oil to be guided into the oil outlet hole 1003, which facilitates oil supply to the upper oil groove 1002. The upper oil groove 1002 is inclined on the same vertical plane, and the inclined lower end of the upper oil groove 1002 is the input end of the filament. This allows the filament to be fully and effectively oiled under the driving force of the filament movement, avoiding oil overflow.

[0042] Example 2

[0043] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that, in order to fully implement the present invention, the specific structure of the control mechanism used for monitoring in the present invention is described in detail.

[0044] Specifically, the control mechanism includes a PLC controller and a wire breakage alarm 11. The wire breakage alarm 11 is installed on the long filament between the oiler 10 and the filament drum 12. The solenoid valve 6 is also equipped with a return oil pipe 603. The PLC controller is electrically connected to the solenoid valve 6 and the wire breakage alarm 11 through a transmission line. The return oil pipe 603 is connected to one end of the third oil supply pipe 13 through the third connector 7, and the other end of the third oil supply pipe 13 is connected to the input end of the oil tank 1.

[0045] In operation, the solenoid valve 6 supplies oil to the oiler 10 through the oil outlet pipe 602. When a wire breaks, the wire breakage alarm 11, which works in conjunction with the broken wire, immediately detects the abnormality. On the one hand, it will sound an alarm to remind the operator, and on the other hand, it will transmit the wire breakage signal to the PLC controller. The PLC controller will control the corresponding solenoid valve 6 to close the oil outlet pipe 602 and open the oil return pipe 603. In this way, the oil output by the solenoid valve 6 will flow back to the oil tank 1 through the third oil supply pipe 13 to achieve timely oil recovery. After the operator rewinds the broken wire onto the spool 12, the wire breakage alarm 11 outputs a normal signal, and the PLC controller will control the solenoid valve 6 to close the oil return pipe 603 and open the oil outlet pipe 602 to achieve normal oil supply during operation.
