DETAILED DESCRIPTION

[0021] The application will be described in detail below with reference to the drawings.

[0022] In order to make the purpose, technical scheme and advantages of the application more clear, the application will be described in further detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the application and do not limit the application.

[0023] A multi-stage linkage automatic protective door provided by the application has the structure as shown in the figure. Figure 1 According to the stroke requirement and actual working condition, a plurality of air cylinders can be installed. Figure 2 Two air cylinders are shown in the figure. The multi-stage linkage automatic protective door mainly comprises a protective door, air cylinders, a sliding seat, a guide rail sliding block, a fixed support, a moving roller support, a connecting ear shaft, a connecting support, a track and the like. The protective door is slidingly installed on a device box body. A driving assembly is installed on the device box body. One side of the driving assembly is fixedly installed on the device box body through a first fixed support and a second fixed support. The first fixed support is fixedly connected with the protective door. The second fixed support is fixedly connected with the device box body. The first fixed support is fixedly connected with the second fixed support. The other side of the driving assembly is fixed on the protective door through a guide rail sliding track. The driving assembly is electrically connected with a control system. The control system controls the movement of the driving assembly, so as to realize the multi-stage linkage automatic opening and closing of the protective door.

[0024] As shown in the figures, Figure 1 , 2 , 3, 1 is a protective door, 2 is a driving assembly, one side of the driving assembly is fixed on a device box body 7 through a first fixed support 3 and a second fixed support 4, and the other side of the driving assembly is fixed on the protective door 1 through a guide rail sliding track 24.

[0025] In this embodiment, a first-stage air cylinder 21 in the driving assembly is fixed with 7. A first connecting support ear 26 matched with the first-stage air cylinder 21 is connected with a sliding seat 25. A second-stage air cylinder 22 in the driving assembly is fixedly connected with the sliding seat 25 at the front end. A second connecting support ear 27 matched with the second-stage air cylinder is fixedly connected with 1. The end of the second-stage air cylinder is connected with a moving roller support 9 through a connecting plate 23, so as to move and support the movement of the second-stage air cylinder on the track 8. The first-stage air cylinder and the second-stage air cylinder are connected with a control system.

[0026] In this embodiment, the driving assembly further comprises a position sensor. The position sensor is fixedly installed on the protective door. The position sensor is connected with the control system.

[0027] In this embodiment, an electronic door lock is installed on the protective door. The electronic door lock is connected with the control system. The locking tongue of the electronic door lock on the protective door collides with a fixed locking rod on a device rotary wheel frame cover after being buffered by a buffer, so as to realize mechanical locking of the door.

[0028] In the embodiment, the observation window is installed on the protective door. After the spinning process is completed, the control system sends a command to the electronic door lock to pop the lock tongue and allow the lock rod to move out, and then the first and second cylinders are correspondingly linked to open the protective door.

[0029] In operation, the slide is located at the front end of the door, the control system sends a command to the first cylinder to move, and the second cylinder is driven by the slide 25 to move the sliding block 6 on the protective door 1 on the equipment guide rail. After the position sensor detects that the first cylinder has moved to the position, the control system sends a command to the second cylinder to move, and the second cylinder directly pushes the protective door forward. Before the position sensor detects that the protective door approaches the locked position, the control system slows down the second cylinder through the pneumatic control valve element, and the lock tongue of the electronic door lock 5 on the protective door collides with the fixed lock rod 10 on the equipment rotary wheel cover through the buffer 11 to achieve mechanical locking. An observation window is installed on the protective door, and after the spinning process is completed, the control system sends a command to the electronic door lock 5 to pop the lock tongue and allow the lock rod to move out, and then the first and second cylinders are correspondingly linked to open the protective door. Thus, the automatic opening and closing of the multi-stage linkage protective door is repeated to realize the automatic feeding and discharging of the spinning machine.

[0030] The automatic protective door is driven by multiple cylinders, and the control system is linked to realize the linkage action of the first and second cylinders to move the protective door to realize automatic closing. When opening, the control system controls the lock tongue of the electronic door lock to pop out and allow the lock rod to move out, and then the first and second cylinders are correspondingly linked to open the protective door. The guide rail sliding block is installed above and below the protective door to ensure that the protective door is automatically opened and closed smoothly. The end of the second cylinder is also provided with a movable support to ensure the stable operation of the second cylinder. The overall structure is compact, the operation is reliable and flexible, and the application has important significance for improving the automation level of the spinning machine and improving the production efficiency.

[0031] The present application is not limited to the foregoing specific embodiments. The present application extends to any new feature or any new combination disclosed in the specification, and any new method or process disclosed in the specification or any new combination of steps or any new combination.
