DETAILED DESCRIPTION

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The specific structure of a multi-stage linkage automatic protection door provided by the present invention is shown as follows: Figure 1 As shown. Multiple cylinders can be installed according to the stroke requirements and actual working conditions. Figure 2 Two cylinders are shown in the figure. A multi-stage linkage automatic protective door is mainly composed of a protective door, a cylinder, a slide, a guide rail slider, a fixed support, a movable roller support, a connecting ear shaft, a connecting support, a track, etc. The protective door is slidably installed on the equipment box, and a drive assembly is installed on the equipment box. One side of the drive assembly is fixedly installed on the equipment box through a first fixed support and a second fixed support. The first fixed support is fixedly connected to the protective door, the second fixed support is fixedly connected to the equipment box, and the first fixed support is fixedly connected to the second fixed support; the other side of the drive assembly is fixed to the protective door through a guide rail slide; the drive assembly is electrically connected to the control system, and the movement of the drive assembly is controlled by the control system, thereby realizing the multi-stage linkage automatic opening and closing of the protective door.

[0024] like Figure 1 , 2 As shown in , 3 , 1 is a protective door, 2 is a driving assembly, one side of the driving assembly is fixed to the equipment box 7 through the first fixed support and the second fixed support 3 and 4, and the other side is fixed to the protective door 1 through the guide rail 24.

[0025] In this embodiment, the primary cylinder 21 in the driving assembly is fixed to 7, and the first connecting lug 26 matched therewith is connected to the slide 25; the front end of the secondary cylinder 22 in the driving assembly is fixedly connected to the slide 25, and the second connecting lug 27 matched therewith is fixedly connected to 1, and the end of the secondary cylinder is connected to the moving roller support 9 through the connecting plate 23, which is used to move and support the movement of the secondary cylinder on the track 8. The primary cylinder and the secondary cylinder are connected to the control system.

[0026] In this embodiment, the driving assembly further includes a position sensor, which is fixedly mounted on the protective door and connected to the control system.

[0027] In this embodiment, an electronic door lock is installed on the protection door, and the electronic door lock is connected to the control system. The lock tongue of the electronic door lock on the protection door collides with the fixed lock rod on the equipment rotating wheel frame shield and is buffered by the buffer to realize mechanical door locking.

[0028] In this embodiment, an observation window is installed on the protective door. After the spinning process is completed, the control system issues a command for the electronic door lock tongue to pop open and release the lock rod, and then the primary and secondary cylinders act in conjunction with each other to open the protective door.

[0029] During operation, the slide is located at the front end of the door. The control system issues a command to the first cylinder to move, and the slide 25 drives the second cylinder to push the slider 6 on the protective door 1 on the equipment rail. After the position sensor detects that the first cylinder is in place, the control system issues a command to the second cylinder to move, and the second cylinder directly pushes the protective door forward. When the position sensor detects that it is close to the door lock position, the control system uses the pneumatic control valve element to decelerate the second cylinder, 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 frame shield and is buffered by the buffer 11 to achieve mechanical door locking. An observation window is installed on the protective door. After the spinning process is completed, the control system issues a command for the lock tongue of the electronic door lock 5 to pop open and let the lock rod go. Then the first and second cylinders act in conjunction to open the protective door. This is repeated to complete the automatic opening and closing of the multi-stage linkage protective door, and realize the automatic loading and unloading of the spinning machine.

[0030] The automatic protective door is driven by a multi-stage cylinder, and the control system is linked to realize the linkage action of the first and second stage cylinders, pushing the protective door to realize automatic closing action. When opening, the control system controls the lock tongue of the electronic door lock to pop open and release the lock rod, and then the first and second stage cylinders are linked to realize the opening of the protective door. Guide rail sliders are installed above and below the protective door to ensure that the protective door opens and closes smoothly and automatically; a movable support is also installed at the end of the second stage cylinder to ensure the smooth operation of the second stage cylinder. The overall structure is compact, and the operation is reliable and flexible; the present invention is of great significance to improving the automation level of the spinning machine and improving production efficiency.

[0031] The present invention is not limited to the above-mentioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
