Hand-cranked machines require continuous manual operation, resulting in low efficiency; while electric recycling machines are more automated, they cannot automatically identify whether the cotton thread needs recycling, leading to the thread often being treated as a disposable item and wasting resources. Furthermore, existing equipment lacks intelligent control, is inconvenient to operate, and cannot be moved flexibly. Utility Model Content

[0016] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] Please refer to Figure 1 and Figure 2 A simple automatic cotton thread recycling device includes a frame 1, a cotton thread recycling mechanism 3 mounted on the frame 1, and a control system. The cotton thread recycling mechanism 3 includes a cotton thread winding assembly driven by a motor 31. The control system includes a signal detection unit 4 and a PLC controller 5. The signal detection unit 4 is configured to detect whether the cotton thread is under stress and send a detection signal. The PLC controller 5 controls the start and stop of the motor 31 according to the detection signal. The cotton thread winding assembly is used to wind and recycle the cotton thread 2 under the drive of the motor 31.

[0018] The beneficial effects of this utility model are as follows: This simple automatic cotton thread recycling device integrates a signal detection unit 4 based on the lever principle and a PLC intelligent control system, realizing full automation and intelligence of the cotton thread recycling process. The device can monitor the tension of the cotton thread in real time, automatically starting recycling only when the cotton thread loosens due to the removal of the glass, and automatically stopping when recycling is completed or the cotton thread is re-tensioned. This completely changes the situation where traditional electric recycling machines require manual intervention or are laborious to operate manually, achieving unattended operation.

[0019] Furthermore, in the above-mentioned simple automatic cotton thread recycling device, the signal detection unit 4 includes a lever mechanism 41 and an infrared sensor 47. The lever mechanism 41 is connected to the cotton thread. When the cotton thread is under force, the lever mechanism 41 triggers a first position. When the cotton thread is not under force, the lever mechanism 41 triggers a second position. The infrared sensor 47 is configured to detect the position of the lever mechanism 41 and send a signal to the PLC controller 5.

[0020] As described above, the signal detection unit 4 is specifically configured to accurately detect the state of the cotton thread through a lever and an infrared sensor 47, ensuring accurate timing of the recovery.

[0021] Furthermore, in the aforementioned simple automatic cotton thread recycling device, the lever mechanism 41 includes a first fixed threading hole rod 42 through which the cotton thread passes in sequence, a movable threading hole rod 43, and a second fixed threading hole rod 44. The movable threading hole rod 43 includes a fixed end and a threading end opposite to the fixed end for the cotton thread to pass through. The movable threading hole rod 43 can rotate around its fixed end under the control of the cotton thread tension.

[0022] As can be seen from the above description, the lever mechanism 41 has a simple and reliable structure, responds quickly, and adapts to changes in cotton thread tension.

[0023] Furthermore, in the aforementioned simple automatic cotton thread recycling device, the frame 1 is also provided with an upper limit rod 45 and a lower limit rod 46 for limiting the rotation range of the movable threading hole rod 43.

[0024] As described above, the upper limit rod 45 and the lower limit rod 46 are located at the beginning and end of the rotation trajectory of the movable threading hole rod, respectively. The combination of the two limit rods limits the rotation range of the movable threading hole rod 43 and improves the response accuracy of the lever mechanism 41.

[0025] Furthermore, in the aforementioned simple automatic cotton thread recycling device, the cotton thread winding assembly includes a cotton thread diverter 32 and a cotton thread winding body. The cotton thread diverter 32 is connected to the motor 31 for transmission. The cotton thread winding body includes a cotton thread sleeve 34 fixed on the frame 1 and a cotton thread base 33 rotatably sleeved on the cotton thread sleeve 34. The cotton thread diverter 32 abuts against the cotton thread base 33 and is configured to drive the cotton thread base 33 to rotate so that the cotton thread is evenly wound on the cotton thread base 33.

[0026] As described above, in the specific structure of the cotton thread winding assembly, the cotton thread distributor 32 directly drives the cotton thread base 33 to rotate, and the two are synchronized through friction transmission. This design is not only highly efficient in transmission, but more importantly, it can guide the cotton thread to be laid out in an orderly and uniform manner on the take-up drum, fundamentally avoiding problems such as messiness and thread jamming caused by uneven winding, and ensuring the direct reusability of the recycled cotton thread.

[0027] Please refer to Figure 3 Furthermore, in the above-mentioned simple automatic cotton thread recycling device, the cotton thread winding assembly also includes a spring 35, a threaded rod 36 and a rotating rod 37. One end of the spring 35 is connected to the threaded rod 36 and the other end is connected to the frame 1. The rotating rod 37 is rotatably connected to the frame 1, and the threaded rod 36 passes through the middle of the rotating rod 37 and is connected to the cotton thread sleeve rod 34.

[0028] As described above, the rotating rod 37 is rotatable, and since the threaded rod 36 passes through the middle of the rotating rod 37, the threaded rod 36 can rotate around the middle of the rotating rod 37. Through the continuous pressure provided by the spring 35 and the floating support formed by the rotating rod 37, a stable and moderate contact pressure is always maintained between the thread distributor 32 and the thread base 33. This ensures the reliability of the friction drive; even if the thread base 33 slightly sinks due to the increased diameter of the wound thread, it can automatically compensate, maintaining a constant take-up torque and preventing slippage due to insufficient pressure or wear caused by excessive pressure.

[0029] Furthermore, in the aforementioned simple automatic cotton thread recycling device, the frame 1 is provided with a coaxial first fixed tube 38 and a second fixed tube 39, and the two ends of the rotating rod 37 are respectively rotatably sleeved inside the first fixed tube 38 and the second fixed tube 39.

[0030] As described above, the rotating rod 37 is fitted inside the first fixed tube 38 and the second fixed tube 39. The rotating rod 37 is not in a locked state. The diameter of the holes in the two fixed tubes is 1 mm larger than the diameter of the rotating rod 37. The above structure allows the rotating rod 37 to rotate flexibly and stably.

[0031] Furthermore, in the aforementioned simple automatic cotton thread recycling device, casters are installed at the bottom of frame 1.

[0032] As described above, the omnidirectional wheels enhance the mobility and site adaptability of the device, allowing operators to easily move it to any location next to the production line where cotton thread needs to be recycled.

[0033] Furthermore, the aforementioned simple automatic cotton thread recycling device also includes an operating panel, which is equipped with a start button, a pause button, and an emergency stop button. The operating panel is electrically connected to the PLC controller 5.

[0034] Furthermore, in the aforementioned simple automatic cotton thread recycling device, there are two cotton thread recycling mechanisms 3, which are symmetrically distributed on both sides of the frame 1.

[0035] As described above, two or more cotton thread recycling mechanisms can be installed on the frame, which improves the utilization rate of the frame.

[0036] Furthermore, in the aforementioned simple automatic cotton thread recycling device, the device is powered by a storage battery.

[0037] As described above, using battery power reduces power cord limitations and expands the scope of application.

[0038] Example 1 Please refer to Figures 1 to 3A simple automatic cotton thread recycling device includes a frame 1, a cotton thread recycling mechanism 3 mounted on the frame 1, and a control system. The cotton thread recycling mechanism 3 includes a cotton thread winding assembly driven by a motor 31. The control system includes a signal detection unit 4 and a PLC controller 5. The signal detection unit 4 is configured to detect whether the cotton thread is under stress and send a detection signal. The PLC controller 5 controls the start and stop of the motor 31 according to the detection signal. The cotton thread winding assembly is used to wind and recycle the cotton thread 2 under the drive of the motor. Casters are installed at the bottom of the frame 1.

[0039] The signal detection unit 4 includes a lever mechanism 41 and an infrared sensor 47. The lever mechanism 41 is connected to the cotton thread. When the cotton thread is under force, the lever mechanism 41 triggers a first position. When the cotton thread is not under force, the lever mechanism 41 triggers a second position. The infrared sensor 47 is configured to detect the position of the lever mechanism 41 and send a signal to the PLC controller 5.

[0040] The lever mechanism 41 includes a first fixed threading hole rod 42 through which the cotton thread passes, a movable threading hole rod 43, and a second fixed threading hole rod 44. The movable threading hole rod 43 includes a fixed end and a threading end opposite to the fixed end for the cotton thread to pass through. The movable threading hole rod 43 can rotate around its fixed end under the control of the cotton thread tension. The frame 1 is also provided with an upper limit rod 45 and a lower limit rod 46 for limiting the rotation range of the movable threading hole rod 43.

[0041] The cotton thread winding assembly includes a cotton thread diverter 32 and a cotton thread winding body. The cotton thread diverter 32 is connected to the motor 31 for transmission. The cotton thread winding body includes a cotton thread sleeve 34 fixed on the frame 1 and a cotton thread base 33 rotatably sleeved on the cotton thread sleeve 34. The cotton thread diverter 32 abuts against the cotton thread base 33 and is configured to drive the cotton thread base 33 to rotate so that the cotton thread is evenly wound on the cotton thread base 33.

[0042] The cotton thread winding assembly also includes a spring 35, a threaded rod 36, and a rotating rod 37. One end of the spring 35 is connected to the threaded rod 36, and the other end is connected to the frame 1. The rotating rod 37 is rotatably connected to the frame 1, and the threaded rod 36 passes through the middle of the rotating rod 37 and connects to the cotton thread sleeve rod 34. The frame 1 is provided with a coaxial first fixed tube 38 and a second fixed tube 39, and the two ends of the rotating rod 37 are respectively rotatably sleeved inside the first fixed tube 38 and the second fixed tube 39.

[0043] The simple automatic cotton thread recycling device also includes an operating panel equipped with a start button, a pause button, and an emergency stop button. The operating panel is electrically connected to the PLC controller 5. The simple automatic cotton thread recycling device is powered by a storage battery.

[0044] The working principle and process of the above-mentioned simple automatic cotton thread recycling device are as follows: Initial state: The device is in place and braked. The cotton thread is led out from the glass interlayer and passes through each threading hole rod in sequence. At this time, the cotton thread is under tension, pulling the movable threading hole rod so that its upper end abuts against the upper limit rod and is within the sensing area of ​​the infrared sensor. The PLC controller receives the "cotton thread under tension" signal, controls the motor to stop, and the device enters standby mode.

[0045] Automatic trigger recovery: When a worker removes a piece of glass, the corresponding thread loses tension and slackens. The movable threading rod rotates around its axis under its own weight, its lower end falling to the lower limit rod, while its upper end moves away from the sensing area of ​​the infrared sensor. When the sensor signal disappears, the PLC controller immediately determines that "the thread needs to be recovered" and starts the motor.

[0046] Recovery and winding process: After the motor starts, it drives the thread divider to rotate. Due to the spring pressure, the thread divider drives the thread base to rotate synchronously through friction, beginning to wind and recover the slack thread. While the thread divider rotates, the rotating rod and spring structure ensure that throughout the winding process, even as the winding diameter of the thread base gradually increases, the thread divider maintains effective contact pressure, guaranteeing stable transmission.

[0047] Automatic Stop: During the recycling process, when the cotton thread is tightened again, the movable threading hole rod will be raised to its upper limit again, triggering the infrared sensor. After receiving the signal, the PLC controller immediately stops the motor, completing one recycling cycle.

[0048] Manual intervention and maintenance: When the cotton thread base is full, the worker can press the "pause" button on the control panel to stop the motor and quickly replace it with a new cotton thread base. In any emergency, the "emergency stop" button can be pressed.

[0049] In summary, this utility model, through the above-described structure and workflow, achieves the following: 1. Intelligent control: Through self-developed control program, precise recycling is achieved, and 100% of cotton thread can be recycled and reused multiple times, reducing resource waste, promoting green and low-carbon development, and reducing auxiliary material costs by approximately RMB 15,000 per year; 2. Cost advantage: Replacing market purchases of 40,000-50,000 yuan with self-made costs of less than 3,000 yuan improves the cost-effectiveness by 15 times; 3. Improved efficiency: 400% higher efficiency than traditional manual labor, 80% reduction in labor intensity for operators; avoids waste of human resources during personnel recovery, and is expected to increase labor efficiency by 100,000 yuan; 4. Safety Protection: PLC programming combined with stepper motor control and button operation, photoelectric sensor protection, effectively eliminates safety hazards. Woven cotton threads piled on the ground can cause safety hazards; the recycling device improves on-site safety. The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
