[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. When the main body of the paralleling machine stops, due to inertia, the rollers inside it still rotate. The controller can control the rotation time and frequency of the low-speed motor, so that the time for the plug to slide out of the socket is greater than the time required for the roller to stop rotating due to inertia. The low-speed motor is driven by the controller to rotate, and the low-speed motor drives the threaded rod to rotate in the support plate, so that the threaded rod drives the threaded sleeve to rotate, and the two threaded sleeves slowly move back to back on the threaded rod, so that the threaded sleeve is transmitted through the connection between the connecting rod and the pin shaft, so that the connecting seat drives the moving plate to move, and the moving plate drives the plug to slowly slide out of the socket until the plug completely slides out of the socket. At this time, the roller has stopped rotating, so the operator can use the handle to pull open the protective rod to operate, to avoid the situation where the equipment is shut down but not completely stopped. When the operator opens the safety railing and touches the yarn, he may get his hands or other body parts caught in the rollers, causing personal injury.

[0015] 2. During the operation of the machine, the controller can indirectly make the two threaded sleeves move toward each other, so that the threaded sleeves indirectly drive the movable plate to move toward the socket, and then the plug is inserted into the socket, so that the plug limits the connecting frame, and the connecting frame limits the protective rod, so that it can be opened even when the equipment is in operation without causing any safety hazards.

When the plug 6 slides out of the socket 5, the roller basically stops rotating. The controller 9 can control the rotation time and frequency of the low-speed motor 8, so that the time for the plug 6 to slide out of the socket 5 is greater than the time required for the roller to stop rotating due to inertia, and finally avoids the situation where the equipment is shut down but not completely stopped.

At the same time, the guard plate 22 facilitates the fixed installation of the controller 9, and the controller 9 and the low-speed motor 8 are electrically connected.

[0027] When the paralleling machine body 1 is stopped, due to inertia, the roller inside it is still rotating. The controller 9 can control the rotation time and frequency of the low-speed motor 8, so that the time for the plug 6 to slide out of the socket 5 is longer than the time required for the roller to stop rotating due to inertia. The low-speed motor 8 is driven by the controller 9 to rotate, and the low-speed motor 8 drives the threaded rod 16 to rotate in the support plate 15, so that the threaded rod 16 drives the threaded sleeve 17 to rotate, and the two threaded sleeves 17 move slowly in the back on the threaded rod 16, so that the threaded sleeve 17 is connected through the connecting rod 19 and the pin shaft 20 for transmission, so that the connecting seat 18 drives the movable plate 7 to move, and the movable plate 7 drives the plug 6 to slowly slide out of the socket 5 until the plug 6 is completely When the roller is fully slid out of the socket 5, the roller has stopped rotating, so the operator can pull open the protective rod 4 by the handle 14 to operate, so as to avoid the situation where the equipment is shut down but not completely stopped, and the operator opens the safety railing to touch the yarn, which may cause the hands or other body parts to be drawn into the roller, causing personal injury.
