Referring to fig. 5 and 6, in some embodiments, the feed mechanism 400 includes a housing 410, a feed arm 420, and a clamp assembly 430, the feed arm 420 being coupled to the clamp assembly 430, the clamp assembly 430 being for clamping a single tubular, the feed arm 420 extending from the housing 410 to move the single tubular. The feeding mechanism 400 is composed of a plurality of components, and the shell 410 is arranged to wrap part of the components of the feeding mechanism 400, so that the feeding mechanism 400 is more attractive and simpler in structure, corrosion of air and water to the components of the feeding mechanism 400 is reduced, and the service life of the feeding mechanism 400 is prolonged. In addition, the feeding arm 420 is telescopically arranged in the housing 410, so that the structural design of the feeding mechanism 400 is more reasonable. The feeding arm 420 extends out during feeding and controls the clamping assembly 430 to clamp a single pipe, so that the feeding mechanism 400 can stably and accurately position and convey the pipe.

Referring to fig. 5 and 6, in some embodiments, the clamping assembly 430 includes a fourth driving member 431, a clamping member 432, a fifth driving member 433 and a guide rail 434, the clamping member 432 is mounted on the guide rail 434, the clamping member 432 includes a first clamping member 4321 and a second clamping member 4322, the fourth driving member 431 is connected with one end of the guide rail 434 to control the rotation of the guide rail 434, and the fifth driving member 433 is connected with the guide rail 434 to control the distance between the first clamping member 4321 and the second clamping member 4322.

When the clamping assembly 430 is used, the fourth driving member 431 controls the guide rail 434 to rotate upwards, the clamping member 432 is also driven upwards by the guide rail 434, and limits the pipe between the first clamping member 4321 and the second clamping member 4322, and then the fifth driving member 433 controls the distance between the first clamping member 4321 and the second clamping member 4322, so as to clamp the pipe, and the conveying of the pipe is more stable and accurate. When the clamping assembly 430 does not work, the fourth driving member 431 controls the guide rail 434 to rotate so that the clamping member 432 is horizontally placed, so that the pipe can move on the feeding mechanism 400, thereby improving the practicability of the pipe feeding device,

the clamping member 432 may be cylindrical or rectangular, and may clamp the pipe, and the shape is not limited in this embodiment. In addition, the fourth driving member 431 may be a motor or a rotary cylinder, and the rotation direction of the guide rail 434 may be controlled, and the fifth driving member 433 may be a clamping cylinder or a motor, and may be controlled to clamp and release the pipe by the first clamping member 4321 and the second clamping member 4322, which is not limited in this embodiment.

Referring to fig. 5 and 6, in some embodiments, the clamping assembly 430 further includes a base 435, a centering roller 436, and a transition plate 437, the centering roller 436 being located on a first side of the base 435, the centering roller 436 being used to adjust the position of the single tube relative to the clamping member 432; the transition plate 437 is located on the side of the feeding mechanism 400, the side is the same side as the first side, and the transition plate 437 is used for smoothly feeding the tube to the clamping part 432. When the clamping assembly 430 is used, the pipe between the first clamping member 4321 and the second clamping member 4322 is moved toward the center of the aligning roller 436 by the aligning roller 436, so that the clamping member 432 can clamp the pipe more stably. In addition, due to the arrangement of the transition plate 437, when the pipe moves from the feeding arm 420 to the clamping piece 432, the pipe can slowly fall between the first clamping piece 4321 and the second clamping piece 4322, so that the pipe is more stably transported.

It can be understood that the aligning roller 436 is a columnar structure with two ends having a slightly larger cross-sectional area than the center, and when the pipe passes through the ferry 437 and arrives at the aligning roller 436, since the two ends of the aligning roller 436 are slightly thicker than the center, the pipe will move to the middle position of the aligning roller 436 to align with the middle of the clamping member 432, so that the clamping member 432 can clamp the pipe conveniently.

Since the feeding mechanism 400 does not work, the feeding arm 420 may be extended by mistake to affect the order of the feeding process. The clutch assembly 450 can simply control the telescopic motion of the feeding arm 420, so that the feeding process is more stable. When the clutch assembly 450 is used, the sixth driving member 453 controls the positioning member 452 to be connected with the connecting member 451, so that the rotating member 440 cannot rotate continuously, and the feeding arm 420 which extends by mistake is limited, and the feeding process is simpler and more orderly.

It should be noted that the rotating member 440 may be a gear chain or a transmission belt, a connecting member 451 may be provided, and the positioning member 452 may be connected to limit the extension of the feeding arm 420, which is not limited in this embodiment.

Referring to fig. 7, in some embodiments, the clutch assembly 450 further includes a fixing element 454 and a second limiting element 455, the fixing element 454 is connected to a sixth driving element 453, the second limiting element 455 is located in a second region 470 of the feeding mechanism 400, and the sixth driving element 453 controls the connection between the fixing element 454 and the second limiting element 455 to control the movement of the rotating element 440. When the clutch assembly 450 is used, the sixth driving member 453 controls the connection between the positioning member 452 and the connecting member 451 to limit the rotation of the rotating member 440, and the fixing member 454 and the second positioning member 455 are provided to reduce the acting force acting on the sixth driving member 453 when the clutch assembly 450 limits the extension of the feeding arm 420, so that the limitation of the clutch assembly 450 is firmer, the service life of the clutch assembly 450 is prolonged, and the maintenance cost is reduced.

It will be appreciated that the second region 470 is a different region from the region where the rotary member 440 is located, and that when the second region 470 is located furthest from the first region 460 on the feeder mechanism 400, the force on the sixth drive member 453 can be reduced more, thereby better extending the life of the clutch assembly 450.

It should be noted that the fixing element 454 and the second limiting element 455 may be a fixing pin and a slot structure, or a buckle structure, and the sixth driving element 453 may be a bidirectional telescopic cylinder or a lever, which is not limited in this embodiment.

Referring to fig. 8, in some embodiments, the limiting mechanism 500 includes a sensing member 510 and a seventh driving member 520, and the seventh driving member 520 is connected to the sensing member 510 to control the sensing member 510 to move to the rack 100. When the separate transportation mechanism 300 transports a single pipe to the output side of the feeding mechanism 400, the limiting mechanism 500 can prevent the pipe from falling out of the rack 100, and when the pipe moves to the preset feeding position, the sensing part 510 can sense that the pipe is transported in place, so that the pipe can be positioned and transported more accurately.
