The utility model relates to steel pipe stacking and packing equipment, which is mainly used for improving the part for bearing steel pipes and comprises a frame 1, and a feeding substrate 2, a current limiting device 3 and a pushing device 4 which are arranged on the frame 1; the feeding substrate 2 is a flat plate and is inclined, the left end of the feeding substrate is lower than the right end of the feeding substrate, and the feeding substrate 2 is used for receiving the steel pipe and enabling the steel pipe to automatically roll from the right side to the left side; the flow limiting device 3 comprises a shaft lever 32, a flow limiting baffle 31 rotatably installed on the shaft lever 32 and a stop block 33 fixed on the frame 1, wherein the flow limiting baffle 31 can rotate relative to the shaft lever 32 to be higher than the feeding substrate 2 and is propped against the stop block 33 leftwards or is integrally lower than the upper side surface of the feeding substrate 2; the aligning device 4 includes an aligning baffle 42 provided at a front side or a rear side, and the aligning baffle 42 is a flat plate and is perpendicular to the front-rear direction. The steel pipe pile up neatly baling equipment still includes loading attachment, magnetism and inhale device, pile up neatly baling device, and loading attachment is located loading attachment 2 left side, the steel pipe just gets into loading attachment after rolling down from loading attachment 2, then through magnetism and inhale device and pile up neatly baling device in proper order, accomplish the pile up neatly baling of steel pipe. The improvement of the embodiment is that the steel pipe is firstly received by the feeding substrate 2, and the preliminary pushing of the steel pipe is finished on the feeding substrate 2, so that the steel pipe is prevented from interfering with other parts when entering the feeding device or being conveyed by the feeding device, and the blocking phenomenon is avoided; and can also realize stopping to the steel pipe on the loading base plate 2, when loading attachment reaches the upper limit to the bearing capacity of steel pipe, just use current limiter 3 to stop the steel pipe on loading base plate 2, let the steel pipe on the loading base plate 2 continue to get into loading attachment after loading attachment's loading pressure reduces again, guarantee pile up neatly baling equipment and remain smooth and orderly operation all the time, avoid appearing the stifled dead condition of production line.

In the above scheme, the pushing baffle plate 42 in the pushing device 4 is a standard for pushing the steel pipe, the steel pipe can be manually pushed at one side far away from the pushing baffle plate 42, and the steel pipe is abutted against the pushing baffle plate 42, so that the pushing of the steel pipe is realized, but the manual operation efficiency is low and unsafe. The leveling device 4 of this embodiment preferably further includes a leveling roller 411 assembly 41, where the leveling roller 411 assembly 41 includes a base 412, a leveling roller 411 rotatably mounted on the base 412, and a driving motor 414 for powering the leveling roller 411, a central axis of the leveling roller 411 is parallel to the leveling baffle 42, at least a part of a height of a roller surface of the leveling roller 411 is consistent with a height of an upper side surface of the feeding substrate 2 corresponding to the front-rear direction, and the driving motor 414 drives the leveling roller 411 to roll toward the leveling baffle 42, where the leveling roller 411 is used to push a steel pipe toward the leveling baffle 42. The steel pipe rolls on the feeding substrate 2, if the pushing roller 411 has a part which is obviously higher than the feeding substrate 2, the steel pipe is blocked from travelling, so the highest point of the roller surface of the pushing roller 411 can only be consistent with the height of the upper side surface of the corresponding feeding substrate 2 along the front-back direction at most, or slightly higher than the height of the upper side surface, provided that the steel pipe can be directly rolled, and the steel pipe is not blocked; however, at the same time, only the roll surfaces which can be contacted with the steel pipe on the leveling roller 411 can push the steel pipe to move towards the leveling baffle plate 42 to perform the leveling function, so that in the embodiment, at least part of the roll surfaces of the leveling roller 411 are consistent with the height of the upper side surface of the feeding substrate 2 corresponding to the roll surfaces along the front-back direction, and the roll surfaces of the roll surfaces are contacted with the steel pipe and perform the leveling function, thereby realizing automatic leveling and improving the leveling efficiency. If the steel pipe rolls over the leveling roller 411 directly, the leveling roller 411 may not be able to push the steel pipe, but of course, a lot of steel pipes are accumulated on the feeding substrate 2, and in this embodiment, it is preferable that the roller surface of the leveling roller 411, which corresponds to the upper side surface of the feeding substrate 2 in the front-rear direction, is located on the right side of the flow limiting baffle 31 and is close to the flow limiting baffle 31, so that even if only a small number of steel pipes are stopped on the feeding substrate 2 by the flow limiting baffle 31, the steel pipe and the leveling roller 411 can be kept in contact for a long time, so that the leveling baffle 42 can fully play the role of leveling the steel pipe, and the leveling effect is improved.

In this way, the middle of the pushing roller 411 is a groove formed by two conical roller portions 413 in a bucket shape, and the roller surfaces of the two conical roller portions 413, which are higher than the feeding substrate 2, can contact with the steel pipes to perform the pushing action, so that the contact area of the pushing roller 411 and the steel pipes is increased, and particularly when a large number of steel pipes are accumulated above the groove, the pushing roller 411 can drive the steel pipes to move together towards the pushing baffle plate 42, the pushing action of the pushing roller 411 is fully exerted, and the pushing efficiency of the large-amplitude pipe is improved. The above improvement needs to solve the problem that the part of the pushing roller 411 higher than the feeding substrate 2 blocks the steel pipe, so the matched improvement is the arrangement of the springboard 5, the steel pipe rolls onto the springboard 5 before contacting with the pushing roller 411, and the steel pipe falls down forward when separating from the springboard 5, and can directly cross the part of the pushing roller 411 higher than the feeding substrate 2, so that the steel pipe is prevented from being blocked by the pushing roller 411. Since the opposite surfaces of the two conical roller portions 413 are inclined, and the opposite end surfaces are generally perpendicular to the central axis, the problem of blocking of the steel pipe by the end surfaces of the leveling rollers 411 needs to be solved, and the steel pipe above the leveling rollers 411 is blocked by the inclined side surfaces of the conical roller portions 413 when traveling, and can roll directly without being blocked.

Further, preferably, the right end of the springboard 5 is rotatably connected to the feeding substrate 2, while the left end is a free end, a compression spring 6 is disposed between the springboard 5 and the feeding substrate 2, and when the compression spring 6 reaches the maximum compression amount, the highest point of the left end of the springboard 5 is still higher than the highest point of the push-up roller 411, so as to buffer the springboard 5, reduce noise, and simultaneously make the springboard 5 have an upward elastic force on the steel pipe, so that the steel pipe can pass through the portion of the push-up roller 411 higher than the feeding substrate 2 and enter above the push-up roller 411.

When the flow limiting baffle plate 31 is used, the flow limiting baffle plate 31 is rotated to the upper left, the arc-shaped blocking surface 311 faces to the right, the arc-shaped blocking surface 311 is directly connected with a steel pipe on the backlogged feeding substrate 2 and bears the pressure of the steel pipe, and the bearing capacity of the steel pipe can be improved due to the arc shape; in addition, when the steel pipe needs to be put, the current limiting baffle plate 31 needs to be rotated towards the right lower side, at the moment, the arc blocking surface 311 and the steel pipe slide relatively, the arc shape of the arc blocking surface 311 enables the arc blocking surface 311 not to interfere with the steel pipe structurally, and the steel pipe can be smoothly rotated towards the right lower side as long as friction force can be overcome, and damage to the steel pipe is not easy to occur.

When the current limiting baffle 31 rotates to the upper left to stop the steel pipe, if the steel pipe just passes above the current limiting baffle 31, the current limiting baffle 31 can strike the steel pipe, so that the outer periphery of the current limiting baffle 31 is preferably provided with a straight side surface 312 adjacent to the arc blocking surface 311, after the current limiting baffle 31 rotates to the lower right to be wholly lower than the upper side surface of the feeding substrate 2, the straight side surface 312 faces upwards, when the current limiting baffle 31 rotates to the upper left, the steel pipe just above is pulled up by the straight side surface 312, and the steel pipe can slide onto the feeding substrate 2 again along the straight side surface 312 in the continuous rotation process, so that the protection effect on the steel pipe is achieved.
