Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0018] Please see Figures 1-3 , Figure 1 This is a top view of the entire utility model. Figure 2 This is a front view of the entire utility model. Figure 3 This is a side view of the entire utility model.
[0019] This utility model provides a small DTY testing machine, including a workbench 18 and a DTY testing assembly. The DTY testing assembly includes a POY raw yarn placement rack 1, an unwinding tension adjustment rack 2, a ceramic wheel 3, a yarn cutter 4, a CR1 guide plate 5, a twist stopper 6, an electric heating box 7, a cooling plate 8, a texturing device 9, a CR2 guide plate 10, a heating plate 11, an oiling clamp 13, a CR3 guide plate 14, a yarn breakage detection rack 15, a forming winder 16, a parameter setting screen 17, and POY raw yarn 19. This solution addresses the safety hazards of existing DTY equipment and the high requirements for user space, economic investment, and personnel. It is understood that the aforementioned solution, during actual operation, first... The POY raw yarn 19 is placed on the POY raw yarn placement rack 1. After being led out of the placement rack, the POY raw yarn 19 undergoes tension adjustment via the unwinding tension adjustment rack 2. The unwinding tension adjustment rack 2 can precisely adjust the unwinding tension of the raw yarn according to the test requirements, ensuring that the raw yarn is output with a stable tension state that meets the process requirements. The raw yarn with adjusted tension is led out through the ceramic wheel 3. The ceramic wheel 3 has a smooth surface, which can reduce friction during the lead-out process and protect the surface quality of the raw yarn from damage. After being led out, the raw yarn passes through the yarn cutter 4. The yarn cutter 4 plays a crucial protective role throughout the entire test process. When an abnormality occurs in the raw yarn, such as when the yarn breakage detection rack 15 detects a broken yarn, the yarn cutter 4 will respond quickly and cut the yarn. The raw yarn is unwound after being cut to avoid equipment malfunctions or other safety issues caused by yarn breakage. Simultaneously, it triggers an alarm at the workstation, alerting operators to handle the situation promptly. The raw yarn passing through the yarn cutter 4 enters the CR1 guide plate 5, where it winds four times. The winding design of the CR1 guide plate 5 provides initial shaping and guidance of the raw yarn, ensuring it follows a suitable path to subsequent processes. After winding, the raw yarn passes through the anti-twist device 6, which prevents unnecessary twisting during transport, ensuring the stability of the yarn's twist. Subsequently, the raw yarn enters the electric heating box 7, which heats the yarn according to set temperature parameters, bringing it to a suitable processing temperature to prepare it for subsequent processes such as false twisting. After preparation, the heated POY yarn tow enters the cooling tray 8 for cooling. The cooling tray 8 can quickly reduce the temperature of the yarn tow, setting its shape and ensuring that the yarn tow maintains a stable shape during subsequent processing. The cooled yarn tow then enters the texturing device 9 for false twisting. The texturing device 9, through a special mechanical structure and movement, imparts elasticity to the yarn tow, giving it the required physical properties. The false-twisted yarn tow enters the CR2 guide plate 10, where it is wound four times for further shaping and guiding. The wound yarn tow then enters the heating plate 11 for reheating and setting. The heating plate 11 can precisely control the heating temperature and time, ensuring that the yarn tow is set at a suitable temperature, guaranteeing the stability of the yarn tow's shape and properties.After shaping, the filament bundle enters the networker 12 to form network nodes. The networker 12, through a special airflow, creates network nodes on the filament bundle, enhancing its cohesion and stability. The network-treated filament bundle then undergoes an oiling process using the oiling clamp 13. The oiling clamp 13 evenly applies an appropriate amount of oil to the filament bundle, reducing friction during subsequent processing and use, and improving its antistatic properties and softness. After oiling, the filament bundle passes through the CR3 guide plate 14 four times for over-drawing and shaping. The CR3 guide plate 14 and the over-drawing and shaping process further adjust the size and physical properties of the filament bundle to achieve an ideal state. The drawn and shaped filament bundle then enters the filament breakage detection frame 15, which is online in real time. The monitoring system detects yarn breakage due to process mismatch or other reasons, immediately sending a signal to the yarn cutter 4 and triggering a station anomaly alarm. If the yarn bundle maintains a normal and stable process state throughout the entire process, it enters the forming and winding device 16 for forming and winding. The forming and winding device 16 can neatly wind the yarn bundle into a package of a certain specification according to the set winding parameters, facilitating subsequent storage, transportation, and use. Throughout the test, the operator can set and adjust various parameters of the equipment, such as temperature, tension, and winding speed, through the parameter setting screen 17 to meet different test requirements. Simultaneously, the parameter setting screen 17 can also display the equipment's operating status and various parameter data in real time, allowing the operator to monitor the equipment's operation and promptly identify and resolve problems.
[0020] In this specific embodiment, the POY raw yarn placement rack 1 is disposed above the workbench 18 on one side; the unwinding tension adjusting rack 2 is disposed above the workbench 18 and on one side of the POY raw yarn placement rack 1; the ceramic wheel 3 is disposed above the workbench 18 and on one side of the unwinding tension adjusting rack 2, and the ceramic wheel 3 is also perpendicular to the POY raw yarn placement rack 1; the yarn cutter 4 is disposed above the workbench 18 and on the side of the unwinding tension adjusting rack 2 away from the POY raw yarn placement rack 1; the CR1 guide plate 5 is disposed on the side of the workbench 18 near the POY raw yarn placement rack 1 above it and on the side of the POY raw yarn placement rack 1 away from the unwinding tension adjusting rack 2; and the anti-twist device 6 is disposed on the side of the CR1 guide plate 5 away from the POY raw yarn placement rack 1.
[0021] The electric heating box 7 is located on one side of the POY raw yarn placement rack 1, and is also located on the side of the CR1 guide plate 5 near the filament cutter 4. The cooling plate 8 is located on the upper center side of the workbench 18, and is located on the side of the electric heating box 7 away from the unwinding tension adjustment rack 2. The texturing device 9 is located on the upper side of the workbench 18 away from the POY raw yarn placement rack 1, and is located on the side of the cooling plate 8 away from the electric heating box 7.
[0022] Secondly, the CR2 guide plate 10 is located on the side of the feeder 9 away from the cooling plate 8, the heating plate 11 is located on the side of the CR2 guide plate 10, and the heating plate 11 is also arranged perpendicular to the feeder 9. The oil clamp 13 is located on the side of the heating plate 11 away from the CR2 guide plate 10.
[0023] Meanwhile, the CR3 guide plate 14 is located on the side of the upper oil clamp 13 away from the heating plate 11, and the CR3 guide plate 14 is also located on the upper side of the worktable 18 away from the POY raw yarn placement rack 1. The broken yarn detection rack 15 is located on the side of the CR3 guide plate 14 away from the upper oil clamp 13. The forming winder 16 is detachably connected to the worktable 18 and is located on the upper side of the worktable 18 away from the POY raw yarn placement rack 1. The forming winder 16 is located on the side of the broken yarn detection rack 15 away from the CR3 guide plate 14.
[0024] In addition, the parameter setting screen 17 is detachably connected to the workbench 18 and is located above the center of the workbench 18. The parameter setting screen 17 is located on one side of the cooling plate 8. One end of the POY filament 19 is detachably connected to the POY filament placement rack 1 and is located inside the POY filament placement rack 1. The other end of the POY filament 19 is located on the side of the forming winder 16 near the broken filament detection rack 15.
[0025] In the actual operation of this utility model, the POY raw yarn 19 is first placed on the POY raw yarn placement rack 1. After the POY raw yarn 19 is led out from the placement rack, it passes through the unwinding tension adjustment rack 2 for tension adjustment. The unwinding tension adjustment rack 2 can precisely adjust the unwinding tension of the raw yarn according to the test requirements, so that the raw yarn is output in a stable tension state that meets the process requirements. The raw yarn with the adjusted tension is led out through the ceramic wheel 3. The surface of the ceramic wheel 3 is smooth, which can reduce the friction of the raw yarn during the lead-out process and protect the surface quality of the raw yarn from damage. After being led out, the raw yarn passes through the yarn cutter 4. The yarn cutter 4 plays a key protective role in the entire test process. When the raw yarn has an abnormality, such as the yarn breakage detection rack 15, it will be detected. When a broken filament is detected, the filament cutter 4 responds quickly, cutting and unwinding the filament to prevent equipment malfunctions or other safety issues caused by the broken filament. Simultaneously, it triggers a station anomaly alarm, alerting the operator to handle the situation promptly. The filament passing through the filament cutter 4 enters the CR1 guide plate 5, where it winds four times. The winding design of the CR1 guide plate 5 provides initial shaping and guidance of the filament, ensuring it enters subsequent processes along a suitable path. After winding, the filament passes through the anti-twist device 6, which prevents unnecessary twisting during transport, ensuring the stability of the filament's twist. Subsequently, the filament enters the electric heating box 7, which heats the filament according to set temperature parameters to achieve the desired temperature. The appropriate processing temperature prepares the POY yarn for subsequent false twisting and other processes. The heated POY yarn enters the cooling tray 8 for cooling, which rapidly reduces the yarn temperature and sets its shape, ensuring a stable form during subsequent processing. The cooled yarn then enters the texturing device 9 for false twisting. The texturing device 9, through its special mechanical structure and movement, imparts elasticity to the yarn, giving it the required physical properties. The false-twisted yarn then enters the CR2 guide plate 10, where it is wound four times for further shaping and guidance. After winding, the yarn enters the heating plate 11 for reheating and setting. The heating plate 11 precisely controls the heating temperature and time, ensuring the yarn completes its shaping at the appropriate temperature. The shaping process ensures the stability of the filament bundle's shape and performance. After shaping, the filament bundle enters the networker 12 to form network nodes. The networker 12, through a special airflow action, forms network nodes on the filament bundle, enhancing its cohesion and stability. The network-treated filament bundle then undergoes an oiling operation via the oiling clamp 13. The oiling clamp 13 evenly applies an appropriate amount of oil to the filament bundle, reducing friction during subsequent processing and use, and improving its antistatic properties and softness. After oiling, the filament bundle passes through the CR3 guide plate 14 four times and undergoes over-drawing and shaping. The CR3 guide plate 14 and the over-drawing and shaping process further adjust the filament bundle's size and physical properties to achieve an ideal state.After being drawn and shaped, the yarn bundle enters the yarn breakage detection rack 15. The yarn breakage detection rack 15 monitors the yarn in real time. If a yarn breakage is detected due to process mismatch or other reasons, it immediately sends a signal to the yarn cutter 4 and triggers a station abnormality alarm. If the yarn bundle maintains a normal and stable process state throughout the entire processing, it enters the forming and winding machine 16 for forming and winding. The forming and winding machine 16 can neatly wind the yarn bundle into a package of a certain specification according to the set winding parameters, facilitating subsequent storage, transportation, and use. Throughout the test, the operator can set and adjust various parameters of the equipment, such as temperature, tension, and winding speed, through the parameter setting screen 17 to meet different test requirements. Simultaneously, the parameter setting screen 17 can also display the equipment's operating status and various parameter data in real time, allowing the operator to monitor the equipment's operation and promptly identify and resolve problems.
