[0042] Working principle:

[0043] The power source of the starting roller 11 makes the roller move, and the oil pipe is sent to the roller frame, and the oil pipe is placed in the middle position, so that one end enters the positioning hole of the end positioning block 2 to realize pre-positioning, and this process can be assisted by manual or can be provided with a guide mechanism.

[0044] The two cylinders 3 act to extend the two clamping plates, and the distance of the two cylinders 3 is set according to the size of the oil pipe in this batch, so that the two clamping plates can clamp the oil pipe when merging; even if the tail end of the oil pipe deviates from the center axis, the oil pipe will be pushed to the center axis by the clamping plate and thus clamped and fixed; in addition, the two cylinders 3 can be started manually, or a proximity switch can be arranged in the end positioning hole, and the cylinder starts to start when the oil pipe enters the positioning hole.

[0045] The two clamping plates gradually merge, the pressing block 51 contacts the button 81 and completely presses the button 81 in the continuous merging process, so that the blocking block interrupts the infrared signal, at this time, the code spraying gun receives the disconnected signal of the infrared ray, and the code spraying gun starts the code spraying work.

[0046] Because the code spraying time is fixed, the cylinder is retracted when the infrared ray is disconnected for a certain time (the time is greater than the time required for code spraying), the two clamping plates are separated, the button is reset under the action of the spring and waits for the next work, and the oil pipe is taken away.

[0047] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in any form. Any simple modification, equivalent change and modification made according to the technical essence of the present application to the above embodiments are within the scope of the technical scheme of the present application.
