Description

TECHNICAL FIELD

[0001] The utility model belongs to spinning equipment technical field, especially a spinning frame self locking device for rotor spinning machine. BACKGROUND

[0002] The textile industry is constantly progressing under the impetus of economic and technological development, and rotor spinning, as a key industry, plays a crucial role in the entire textile field. In the current trend of pursuing high efficiency and energy saving, various aspects of the textile industry are actively responding to this goal, striving to improve production efficiency and effectively utilize energy.

[0003] In the existing technology of semi-automatic rotor spinning machines, the core component, the rotor, is a bearing type structure, with the cup head and bearing tightly integrated as one. This integrated design ensures the stability of the rotor during rotation, and is one of the important factors that guarantee the quality of spinning. The entire rotor component is installed on a damping sleeve, which can effectively absorb and reduce the vibration generated during high-speed rotation of the rotor, creating a more stable environment for spinning work.

[0004] In terms of power transmission, the current common method is belt drive, which is widely used due to its simple structure and cost-effectiveness. At the same time, in order to meet the actual needs of the spinning operation process, the spinning machine is equipped with a brake device. When the spinning device is opened, the brake device can quickly act on the rotor, causing it to quickly stop rotating. This function is crucial for ensuring production safety, as it can effectively prevent dangerous situations that may arise from the rotor continuing to rotate after the spinning device is opened, ensuring the safety of operators and the normal operation of spinning work.

[0005] However, with the continuous updating and development of technology, the rotor design of rotor spinning machines has undergone new changes. In the improved rotor design, in order to reduce the load of related components, the rotor is changed to a magnetic type, and the connection method of the rotor and the motor is also changed from the original integral type to a split type. Although this structural change helps to improve the performance of the rotor spinning machine in some ways, it also poses serious safety problems.

[0006] When the spinning device is opened, due to the structural change, the high-speed rotating rotor cannot be quickly stopped like the traditional design. This makes it highly likely that the rotor will fly out of the spinning machine under the strong rotational kinetic energy. Once this happens, the operators working near the spinning machine will be at risk of being hit by the rotor. This safety hazard not only poses a direct threat to the personal safety of operators, but also has a negative impact on the normal production and operation of the enterprise, which may lead to production stagnation, equipment damage and other problems.

[0007] Therefore, in the process of continuous improvement of the rotor spinning machine technology, in order to guarantee the production safety, it is urgent to design a special structure. This structure can effectively prevent the operator from opening the spinning device when the rotor is running at high speed, so as to avoid the accident of the rotor flying out to hurt people, and ensure the safety and stability of the rotor spinning production process. Content of the utility model

[0008] Therefore, the utility model aims at providing a spinning device self-locking device for a rotor spinning machine, which locks the spinning device in the normal spinning process, avoids the misoperation of opening the spinning device, automatically unlocks after the rotor completely stops, and realizes the safe opening function of the spinning device.

[0009] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0010] A spinning device self-locking device for a rotor spinning machine, comprising a front end plate, a sensor, a spinning device, a rotor, a rotor motor, a nylon pin, a positioning block, a fixed shaft, a threaded cylinder and a sensing magnetic steel;

[0011] The front end plate is fixed on the external equipment rack, the rotor motor is arranged at the back of the front end plate, the rotor motor spindle is connected with the rotor through the front end plate, the sensor is arranged at the front of the front end plate, and the threaded cylinder is fixed on the front end plate, and the front moving end is fixedly connected with the nylon pin;

[0012] The spinning device is arranged on the fixed shaft, the fixed shaft is fixed on the external equipment rack, the spinning device is positionally matched with the front end plate, the sensing magnetic steel is arranged on the spinning device and is positionally matched with the sensor, and the positioning block is arranged on the spinning device and is positionally matched with the nylon pin.

[0013] In the above structure, when the spinning device is folded around the fixed shaft and the front end plate, the sensor senses the sensing magnetic steel, when the sensor senses the sensing magnetic steel, the nylon pin enters the positioning block under the pushing of the threaded cylinder, and the spinning device can be locked, and when the rotor stops running, the threaded cylinder automatically retracts, and the spinning device can be opened.

[0014] In a structure that can optimize the foregoing scheme, the rotor is magnetically connected with the rotor motor spindle. The magnetic connection mode can provide a non-contact power transmission, which can effectively reduce friction loss compared with the traditional mechanical connection mode, thereby improving the transmission efficiency of the rotor motor on the rotor, enabling the rotor to rotate more stably and efficiently, which has a positive significance for improving the spinning quality and production efficiency. The magnetic connection makes the connection between the rotor and the rotor motor spindle relatively flexible, and when the rotor or the motor needs to be maintained or replaced, this connection mode can be more conveniently disassembled and installed, reducing the maintenance difficulty caused by the complex connection structure.

[0015] In a structure that can optimize the foregoing scheme, the inductor is installed on the lower left side of the front end plate, and the inductive magnetic steel is positioned in cooperation with the inductor. By installing the inductor on the lower left side of the front end plate, the position of the inductor can be better matched with the inductive magnetic steel arranged on the spinning device, so that the position and state change of the spinning device can be more accurately sensed. This helps to accurately determine whether the spinning device is in the closed, open or opening / closing process. By choosing to install the inductor on the lower left side of the front end plate, the spatial layout of the overall device is also considered to avoid spatial interference with other components (such as threaded air cylinders, nylon pins, etc.), so that the various components can be reasonably distributed, facilitating installation, maintenance and operation.

[0016] In a structure that can optimize the foregoing scheme, the threaded air cylinder is arranged on the lower right side of the front end plate, and the front moving end thereof is fixedly connected with the nylon pin, and the positioning block is positioned in cooperation with the nylon pin. When it is necessary to lock the spinning device, the threaded air cylinder is actuated to push the nylon pin fixedly connected therewith, so that the nylon pin cooperates with the positioning block to prevent the spinning device from being opened; when unlocking, the threaded air cylinder is reversely actuated to pull the nylon pin away from the positioning block.

[0017] Optionally, the threaded air cylinder is of a pneumatic type, and its air source is provided by an external air compressor and controlled by a connected electromagnetic valve to control air intake and exhaust. The electromagnetic valve is connected with the control system of the rotor cup motor, and when the rotor speed sensor of the rotor cup motor detects that the rotor cup stops running (the rotor speed is 0), the control system sends a signal to the electromagnetic valve to make the air cylinder retract; when the inductor detects the inductive magnetic steel signal, the control system sends a signal to the electromagnetic valve to make the air cylinder extend to push the nylon pin to lock.

[0018] In a structure that can optimize the foregoing scheme, the rotor cup motor is a magnetic suspension motor. The magnetic suspension motor has higher efficiency and lower friction, which helps the stable operation of the rotor cup, and cooperates with the overall self-locking device to better adapt to the new design of the rotor cup spinning machine. By using magnetic suspension technology, the rotation of the motor spindle is more stable, driving the rotor cup to rotate. In cooperation with the self-locking device, when the state of the spinning device changes, the operating state of the motor can also be adjusted accordingly to ensure the safe operation of the rotor cup.

[0019] In a structure that can optimize the foregoing scheme, the positioning block has a locking hole formed therein, and the locking hole is on the same axis as the nylon pin (6). The locking hole provides a more accurate positioning and cooperation mode for the nylon pin, enhances the reliability of the spinning device locking, and makes the locking more stable. When the nylon pin is pushed into the locking hole of the positioning block by the threaded air cylinder, a firm locking structure is formed to prevent the spinning device from being accidentally opened; when unlocking, the nylon pin is pulled out of the locking hole.

[0020] In a structure that can optimize the foregoing scheme, further comprising a locking hole and a locking pin, the locking hole is opened on the front end plate, and the locking pin is fixed on the spinning device, and the locking hole and the locking pin are positionally matched. The locking hole and the locking pin can further enhance the locking function between the spinning device and the front end plate, provide additional fixing points, and prevent the spinning device from accidentally separating from the front end plate due to vibration and other reasons during work. When the spinning device and the front end plate are closed, the locking pin fixed on the spinning device is inserted into the locking hole on the front end plate, and cooperates with other locking structures such as the nylon pin and the positioning block to ensure the stable closure of the spinning device; when opened, all related locks need to be released.

[0021] In a structure that can optimize the foregoing scheme, after the front end plate and the spinning device are matched and closed, a cavity is formed inside, and the rotor cup is arranged in the cavity. The cavity provides a suitable working space for the rotor cup, protects the rotor cup from external interference during operation, and ensures that the rotor cup can safely and stably operate in this relatively closed space. After the spinning device is closed around the fixed shaft and the front end plate, a cavity is formed, and the rotor cup rotates in the cavity under the drive of the rotor cup motor. When the spinning device needs to be opened, the rotor cup must be in a safe stop state, and all related locking structures must be released.

[0022] Compared with the prior art, the self-locking device for the rotor cup spinning machine has the following advantages:

[0023] 1. Through the cooperative work of the inductor, the threaded air cylinder, the nylon pin, the positioning block, the locking hole and the locking pin, when the spinning device is folded around the fixed shaft and the front end plate, the spinning device can be accurately locked. Only when the rotor cup stops operating, the spinning device can be opened, thereby avoiding the risk of the rotor cup flying out and injuring the operator due to accidental opening of the spinning device when the rotor cup is operating at high speed, and greatly ensuring production safety.

[0024] 2. The cooperation of the inductor and the inductive magnetic steel can accurately sense the position and state change of the spinning device. At the same time, the control system of the rotor cup motor (especially the magnetic suspension motor) can monitor the parameters such as the rotating speed and the temperature of the rotor cup in real time. When abnormal conditions occur, such as improper opening of the spinning device or abnormal state of the rotor cup, the system can take timely measures, further enhancing the safety of the entire spinning process.

[0025] 3、The magnetic connection between the rotor cup and the rotor cup motor spindle (especially when the rotor cup motor is a magnetic levitation motor) provides a non-contact power transmission method that effectively reduces friction loss and improves the transmission efficiency of the rotor cup motor compared to traditional mechanical connections. This allows the rotor cup to rotate more stably and efficiently, which helps to improve the quality of the spun yarn and the production efficiency. The cavity formed by the cooperation of the front end plate and the spinning device provides a suitable working space for the rotor cup, protecting it from external interference during operation and ensuring its safe and stable operation in a relatively closed space. This ensures the continuity and stability of the spinning process and helps to improve the quality of the spun yarn.

[0026] 4、The pneumatic screw cylinder directly pushes, making the time response more sensitive, and allowing the response time to be arbitrarily changed according to actual needs for more precise control. Moreover, the cylinder has greater thrust, effectively avoiding situations such as jamming and incomplete travel during operation, ensuring the reliable execution of the spinning device locking and unlocking actions. The entire device has a simple and compact structure with reasonable component layout, making it suitable for installation in space-limited areas. This compact structure not only meets functional requirements but also reduces equipment footprint, improving space utilization. During normal spinning, the small air pressure required by the cylinder means that even if it is always open, energy loss is not significant, helping to reduce production costs and improve energy efficiency.

[0027] 5、The device mechanism has been simplified, and the magnetic connection between the rotor cup and the rotor cup motor spindle makes maintenance and replacement more convenient, reducing the difficulty of maintenance due to complex connection structures. At the same time, the simplified structure also makes fault diagnosis and repair easier, which helps to shorten maintenance time and reduce maintenance costs. The device is easy to operate, control is simple and flexible, and can be used on various equipment. Moreover, the simplified device structure helps to improve the cleanliness of the entire machine, reducing the difficulty and workload of cleaning, and further improving the maintainability and service life of the device.

[0038] 1, equipment assembly

[0039] A kind of spinning frame self-locking device for rotor spinning machine, including front end plate 1, inductor 2, spinning frame 3, rotor 4, rotor motor 5, nylon pin 6, positioning block 7, fixed shaft 8, threaded cylinder 9, locking hole 10, locking pin 11.

[0040] The front end plate 1 is firmly fixed on the external equipment rack, and the rotor motor 5 is installed on the back of the front end plate 1, and its main shaft passes through the front end plate 1 and is connected with the rotor 4. The inductor 2 is arranged on the front of the front end plate 1, and the threaded cylinder 9 is fixed on the front end plate 1, and the front moving end thereof is fixedly connected with the nylon pin 6.

[0041] The spinning device 3 is installed on the external equipment rack through the fixing shaft 8, and is positionally matched with the front end plate 1. The inductive magnetic steel is arranged on the spinning device 3, and is positionally matched with the inductor 2 on the front end plate 1. Meanwhile, the positioning block 7 is arranged on the spinning device 3, and is positionally matched with the nylon pin 6. In addition, the locking hole 10 is arranged on the front end plate 1, and the locking pin 11 is fixed on the spinning device 3, and the two are positionally matched.

[0042] When the spinning device 3 is folded to the front end plate 1, a cavity is formed in the inside of the two, and the rotor 4 is located in the cavity. Such a structure design provides a stable working space for the rotor 4, and through the cooperation between the components, the reliable locking and unlocking functions of the spinning device 3 are realized, and the safety and stability of the spinning machine in the running process are ensured.

[0043] 2. Device operation process

[0044] In the actual operation of the rotor spinning machine, the spinning device self-locking device of the embodiment starts to work. The front end plate 1 is firmly fixed on the external equipment rack, and provides stable support for the whole device. The spinning device 3 is installed on the rack through the fixing shaft 8, and can rotate around it, and is positionally matched with the front end plate 1.

[0045] When the spinning device 3 is folded to the front end plate 1 around the fixing shaft 8, the inductive magnetic steel arranged on the spinning device 3 gradually approaches the inductor 2 arranged on the lower left side of the front end plate 1. When the distance between the two reaches the sensing range of the inductor 2, the inductor 2 starts to work, and rapidly transmits the sensing signal to the control system. After receiving the signal, the control system starts the rotor motor 5 located on the back of the front end plate 1, and the main shaft of the rotor motor 5 passes through the front end plate 1 to drive the rotor 4 to start high-speed rotation. At the same time, the control system opens the air valve, and the air source (external air compressor) supplies air to the threaded cylinder 9 (located on the lower right side of the front end plate 1), and the threaded cylinder 9 starts to work, and the part fixedly connected with the nylon pin 6 of the piston rod of the front moving end of the threaded cylinder 9 moves forward, so that the nylon pin 6 is inserted into the locking hole of the positioning block 7, and at the same time, the locking pin 11 fixed on the spinning device 3 is inserted into the locking hole 10 on the front end plate 1, and through this double locking mode, the spinning device 3 is firmly locked, and the spinning device 3 is prevented from being accidentally opened during the operation of the rotor 4.

[0046] In the spinning process, if the yarn breaks, the yarn detector detects the abnormality and transmits a signal to the control system. After receiving the signal, the control system immediately stops the operation of the rotor motor 5. The rotor speed sensor of the rotor motor 5 continuously monitors the rotation speed of the rotor 4, and when the rotor 4 completely stops rotating, the rotor speed sensor feeds back a signal to the control system. The control system then sends a signal to the threaded air cylinder 9 to control the threaded air cylinder 9 to close, so that the piston rod retreats, and the nylon pin 6 and the positioning block 7 and the locking pin 11 and the locking hole 10 are unlocked, and the spinning device 3 is unlocked. At this time, the operator can smoothly open the spinning device 3, clean the rotor 4 and other related operations.

[0047] In this way, the spinning device self-locking device of the embodiment effectively guarantees the safe operation of the equipment and the convenience of operation during the entire spinning process.

[0048] The above only describes the preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
