Description

Technical Field

[0001] This utility model relates to the field of textile processing equipment technology, specifically a POY filament spinning oil rack adjustment device. Background Technology

[0002] In the POY filament spinning process, the position and angle of the spinning oiler play a crucial role in the uniformity and stability of oiling the filament bundle. Traditional spinning oilers are mostly adjusted manually, which has the following core problems: 1. The precision of manual adjustment is difficult to guarantee. Different operators have different adjustment force and methods, which leads to inconsistent contact wrap angle between the oil nozzle and the filament bundle at each spinning position (usually ±2°~3°). This affects the uniformity of oiling the filament bundle and ultimately affects the quality of POY filament. For example, it will cause unevenness of POY yarn (CV value increases by 0.3~0.5 percentage points). When processed into DTY, it is easy to cause false twist tension fluctuations, which affects the weaving performance and wearing performance of DTY fabric. 2. Low response efficiency: When changing product varieties or adjusting process parameters (such as increasing the spinning speed from 3200m / min to 3600m / min), manual adjustment requires operation at each spinning position, and the adjustment time for a single production line exceeds 1.5 hours, which cannot meet the needs of batch production and rapid production changeover. 3. Lack of status monitoring: The oil rack operating status (such as lead screw jamming, motor overload) and oiling effect cannot be monitored in real time, resulting in delayed fault detection and easy to cause batch of wire cake quality defects; 4. Poor compatibility: Traditional oiling racks are mostly fixed structures, which cannot adapt to the oiling nozzle spacing requirements of different yarn bundle specifications (such as fine denier yarn and coarse denier yarn). Changing specifications requires replacing the entire oiling nozzle rack, which increases equipment costs and production changeover time.

[0003] With the upgrading of the chemical fiber industry's demand for "high quality, high automation, and low energy consumption", manual adjustment of the oil rack can no longer meet the needs of modern production. There is an urgent need to develop an automatic adjustment system with multi-dimensional adjustment, status monitoring, and intelligent adaptation. Therefore, developing a POY filament spinning oil rack that can be electrically controlled and adjusted according to process parameters has important practical significance. Utility Model Content

[0004] The purpose of this invention is to provide a POY filament spinning oil rack adjustment device, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: the POY filament spinning oiler adjustment device includes an oiler body, an electric drive mechanism, an angle sensor, and a controller: The oil rack body is positioned above the electric drive mechanism and is used to drive the oil rack body to rotate up and down to adjust the angle. The angle sensor is installed on the oil rack body to detect the angle of the oil rack body in real time and transmit the angle signal to the controller; The controller is electrically connected to the electric drive mechanism and the angle sensor respectively. The controller has pre-stored the oil rack angle data corresponding to different process parameters. The controller compares and analyzes the received angle signal with the angle data corresponding to the preset process parameters. When the two are inconsistent, the controller sends a control command to the electric drive mechanism to drive the electric drive mechanism to work and adjust the angle of the oil rack body to the preset angle.

[0006] Preferably, the oil rack body includes a vertical plate, an oil nozzle frame, a spinning oil nozzle, a support frame, and a slide rail. The oil nozzle frame and the support frame are both mounted on the vertical plate and rotatably connected to the vertical plate. The oil nozzle frame and the support frame are arranged in parallel. The spinning oil nozzle is mounted on the oil nozzle frame, and the slide rail is mounted on the support frame.

[0007] Preferably, the electric drive mechanism includes a mounting plate, a motor, a commutator, a lead screw, and a slide. The motor and the commutator are both mounted on the mounting plate. The output end of the motor is connected to the input end of the commutator. The lead screw is connected to the output end of the commutator. The slide is mounted on the lead screw. The mounting plate has two uprights, each with a sleeve slidably connected to it. The two sleeves are connected by an upper guide rail and a lower guide rail, respectively. The nozzle holder contacts the upper surface of the upper guide rail, and the support frame contacts the upper surface of the lower guide rail. The two sleeves are connected by a base plate, and the slide is fixedly connected to the base plate.

[0008] Preferably, the upper surfaces of both the upper and lower guide rails are provided with support rods, and the upper surfaces of the support rods are arc-shaped.

[0009] Preferably, the upper and lower guide rails are located between the center of gravity of the nozzle holder and the support frame and the upright plate.

[0010] The beneficial effects of this utility model are: This adjustment device, through the cooperation of an electric drive mechanism, an angle sensor, and a controller, achieves precise electric adjustment of the spinning oiler according to process parameters. Compared with traditional manual adjustment, it greatly improves the adjustment accuracy, ensuring that the contact wrap angle between the oil nozzles at each spinning position and the filament bundle is uniform. This ensures uniform oiling of the filament bundle, improves the quality of POY filaments, reduces problems such as uneven POY yarn and false twist tension fluctuations caused by uneven oiling, and enhances the weaving performance and wearability of DTY fabrics.

[0011] The electric control system has a fast response speed and can quickly adjust the oil rack angle when production process parameters change, eliminating the need for manual operation, saving manpower and time, significantly improving production efficiency, and meeting the requirements of modern chemical fiber production for high efficiency and automation.

[0012] The control panel is designed to make it easy for operators to input process parameters, making the entire adjustment process more convenient and intuitive, and reducing the difficulty and labor intensity of the operators' work. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0019] like Figure 1-4 As shown, a POY filament spinning oil rack adjustment device includes an oil rack body, an electric drive mechanism, an angle sensor, and a controller. The oil rack body is positioned above the electric drive mechanism and is used to drive the oil rack body to rotate up and down to adjust the angle. An angle sensor is installed on the oil rack body to detect the angle of the oil rack body in real time and transmit the angle signal to the controller; The controller is electrically connected to the electric drive mechanism and the angle sensor respectively. The controller has pre-stored the oil rack angle data corresponding to different process parameters. The controller compares and analyzes the received angle signal with the angle data corresponding to the preset process parameters. When the two are inconsistent, the controller sends a control command to the electric drive mechanism to drive the electric drive mechanism to work and adjust the angle of the oil rack body to the preset angle.

[0020] Furthermore, the oil rack body includes a vertical plate 2, an oil nozzle frame 3, a spinning oil nozzle 4, a support frame 5, and a slide rail 6. The oil nozzle frame 3 and the support frame 5 are both mounted on the vertical plate 2 and rotatably connected to the vertical plate 2. The oil nozzle frame 3 and the support frame 5 are arranged in parallel. The spinning oil nozzle 4 is mounted on the oil nozzle frame 3, and the slide rail 6 is mounted on the support frame 5.

[0021] The oil rack body is used in conjunction with an oil tank that stores lubricating grease. The oil tank supplies lubricating grease to the spinning nozzle 4 through a hose.

[0022] Furthermore, the electric drive mechanism includes a mounting plate 7, a motor 8, a commutator 9, a lead screw 10, and a slide 11. The motor 8 and the commutator 9 are both mounted on the mounting plate 7. The output end of the motor 8 is connected to the input end of the commutator 9, and the lead screw 10 is connected to the output end of the commutator 9. The slide 11 is mounted on the lead screw 10. Two uprights 12 are mounted on the mounting plate 7. Sleeves 13 are slidably connected to each of the two uprights 12. The two sleeves 13 are connected to each other by an upper guide rail 14 and a lower guide rail 15, respectively. The nozzle holder 3 is in contact with the upper surface of the upper guide rail 14, and the support frame 5 is in contact with the upper surface of the lower guide rail 15. The two sleeves 13 are connected by a base plate 16, and the slide 11 is fixedly connected to the base plate 16.

[0023] After the motor 8 starts, it can drive the lead screw 10 to rotate through the commutator 9. Since the slide 11 is fixedly connected to the base plate 16, the slide 11 can move up / down along the lead screw 10, and drive the upper guide rail 14 and the lower guide rail 15 to move up / down.

[0024] Furthermore, support rods 17 are provided on the upper surfaces of both the upper guide rail 14 and the lower guide rail 15. The upper surfaces of the support rods 17 are arc-shaped, which facilitates the movement of the nozzle holder 3 and the support frame 5 along the arc-shaped surface of the support rods 17 during adjustment.

[0025] Furthermore, the upper guide rail 14 and the lower guide rail 15 are located between the center of gravity of the nozzle holder 3 and the support frame 5 and the upright plate 2, ensuring that the nozzle holder 3 and the support frame 5 can always press against the support rod 17 on the upper guide rail 14 and the lower guide rail 15 under their own weight.

[0026] An angle sensor is installed on the oil holder body to ensure that it can accurately detect the angle of the oil holder body. For example, it can be installed on the oil nozzle holder 3. It also has an operation panel, and the controller is electrically connected to the electric drive mechanism, the angle sensor and the operation panel respectively.

[0027] The adjustment device can also be equipped with a spinning nozzle 4 spacing adjustment component and a spinning nozzle 4 cleaning unit: Spinning nozzle 4 spacing adjustment component: Each spinning nozzle 4 can be independently equipped with a micro stepper motor (torque 0.5Nm) and a linear guide rail. Both the micro stepper motor and the linear guide rail are set on the nozzle holder 3. The stepper motor is electrically connected to the controller and can automatically adjust the nozzle spacing according to the specifications of the yarn bundle 1 (such as denier and number of holes) (adjustment range 5~15mm, accuracy ±0.1mm) to adapt to different yarn bundle 1 width requirements; Spinning oil nozzle 4 cleaning unit: A high-pressure airflow nozzle (air pressure 0.3~0.5MPa) and an oil stain sensor are installed on the outside of the spinning oil nozzle 4. The nozzle is connected to the compressed air pipeline through a solenoid valve. The solenoid valve is electrically connected to the controller. When the oil stain sensor detects that the spinning oil nozzle 4 is blocked (oil stain coverage exceeds 10%), the airflow cleaning is automatically started to avoid oil dripping and contaminating the yarn bundle 1.

[0028] Work process: 1. Automatic adjustment process start-up and parameter call: The process operator selects the POY specification (such as 200D / 144F) through the operation panel, and the controller retrieves the corresponding parameters (oil rack angle 18°, oil nozzle spacing 10mm, oil content 1.3%) from the process control computer. 2. Initial state detection: The multi-dimensional monitoring module synchronously collects data on the current oil rack angle, oil nozzle spacing, and oil supply, and transmits it to the main controller; 3. Deviation Analysis and Adjustment: The controller compares the actual data with the preset value. If there is a deviation (e.g., angle 17.5°, deviation -0.5°), a control command is issued. 4. Start of electric drive mechanism: Motor 8 drives lead screw 10 to rotate through commutator 9, which drives slide 11 to move and adjusts the angle of oil nozzle bracket 3 and support bracket 5 to 18°. The angle sensor provides real-time feedback. When the deviation is ≤0.1°, motor 8 stops (a speed reducer can be set between motor 8 and commutator 9 to improve the angle control accuracy). 5. Oil nozzle spacing adjustment: A micro stepper motor drives the spinning oil nozzle 4 to move along the linear guide rail, and a laser spacing sensor monitors the spacing. The stepper motor stops when the spacing reaches 10mm. 6. Closed-loop control of oil supply: The infrared oil supply sensor detects the oil supply in real time. If the actual value is 1.2% (lower than the preset 1.3%), the main controller fine-tunes the nozzle holder angle by 3 degrees (+0.3°) until the oil supply stabilizes at 1.3%±0.05%. 7. Status maintenance: When the oil level sensor detects that the lubricating grease in the oil tank is less than 20%, the controller controls the grease pump to replenish grease (5mL each time); when the oil stain sensor detects that the spinning nozzle 4 is blocked, high-pressure airflow cleaning is started (lasts for 2 seconds, air pressure 0.4MPa).

[0029] The multi-dimensional monitoring module enables full-state monitoring: 1. Spacing sensor: A laser displacement sensor (accuracy ±0.05mm) is used and installed on the outside of the oil nozzle frame 3 to detect the vertical spacing between the spinning oil nozzle 4 and the yarn bundle 1 in real time. The spacing signal is transmitted to the controller to ensure the spacing is stable (e.g., if the set value is 8mm, the adjustment is triggered when the deviation exceeds ±0.2mm).

[0030] 2. Oil quantity monitoring sensor: An infrared transmission sensor is used and installed on the outlet side of the fiber bundle 1. The oil quantity is calculated by detecting the light transmittance of the fiber bundle 1 (accuracy ±0.05%). When the actual oil quantity deviates from the preset value (e.g., 1.2%) by more than ±0.1%, the controller will adjust the angle of the oil nozzle holder 3 or the oil nozzle spacing in conjunction.

[0031] 3. Vibration sensor: Installed on the housing of commutator 9, it detects the vibration amplitude of the equipment (normal threshold ≤ 0.15 mm / s). When the vibration exceeds the limit, it is judged that the lead screw 10 is stuck or the bearing is worn, triggering a fault warning.

[0032] Troubleshooting process: 1. Fault identification: If the vibration sensor detects a vibration amplitude of 0.2 mm / s in the reducer (exceeding the threshold of 0.15 mm / s), the controller determines it as "lead screw 10 stuck"; 2. Tiered response: The red light on the operation panel flashes and a buzzer alarm sounds. At the same time, fault information is pushed to the MES system (such as "spinning position 3, screw 10 is stuck, it is recommended to check lubrication or foreign objects"). If it is not resolved within 10 seconds, it will automatically switch to the backup electric drive mechanism to avoid adjustment interruption. 3. Fault recovery: After the maintenance personnel troubleshoot the fault (such as removing foreign objects from the lead screw 10 and replenishing lubrication), they reset the fault through the operation panel, the controller resumes the operation of the main drive mechanism, and records the fault handling data (time, method, recovery time).
