As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, an embodiment of the present invention provides a laser pipe cutter feeder, which includes a supporting mechanism 100, a floating mechanism 200, and a limiting mechanism 300. In one specific example, the laser pipe cutter feeder further has a frame 400, and it is understood that the frame 400 is used to fix the carrying mechanism 100, the floating mechanism 200 and the limiting mechanism 300.

To facilitate a further understanding of the components of the laser pipe cutter downer, reference is made to FIG. 2, which illustrates one embodiment of a carriage mechanism 100.

The bearing mechanism 100 includes a rolling member 110 and a tube bearing plate 120, a rolling member mounting hole is formed on the tube bearing plate 120, the rolling member 110 is disposed in the rolling member mounting hole, and a rolling shaft of the rolling member 110 is fixed on the tube bearing plate 120. Referring also to fig. 1, the rolling elements 110 partially protrude from the working surface of the tube carrier plate 120. The working surface of the tube carrier plate 120, i.e., the surface on the side that is adjacent to the tube when it is in operation, is understood to be the upper surface of the tube carrier plate 120, depending on the orientation shown in the figure.

In one specific example, the rolling axis of the rolling member 110 is perpendicular to the extending direction of the tube loading plate 120. It will be understood that the tube carrier plate 120 is used to carry tubes during operation, and the direction of extension is the direction of extension of the tubes that are carried during operation.

In one specific example, the tube carrier plate 120 is secured to the frame.

In one specific example, a rolling member base 130 is further fixedly connected to the tube loading plate 120, and the rolling shaft of the rolling member 110 is fixed to the tube loading plate 120 through the rolling member base 130. Optionally, the roller mount 130 is affixed to a non-working surface, i.e., a lower surface or side, of the tube carrier plate 120.

The tubular product itself need be pulled or rotatory in the course of working, if utilize tubular product loading board 120 direct support panel, then can produce huge frictional force between tubular product and the tubular product loading board 120, and this not only makes tubular product be difficult to remove, still can scrape colored tubular product surface. In order to overcome the problem, the rolling parts 110 protruding out of the surface of the pipe loading plate 120 are creatively introduced, the pipe is in direct contact with the rolling parts 110 when moving, the frictional resistance is greatly reduced, and the obvious scraping of the surface of the pipe cannot be caused by moving or rotating the pipe due to the obvious reduction of the contact area.

In one specific example, there are a plurality of rolling members 110, and the tube carrier plate 120 has rolling member mounting holes corresponding to the number of rolling members 110. Further, the adjacent rolling element mounting holes are arranged at intervals. The plurality of rolling elements 110 help to prevent as much as possible a long tube from coming into direct contact with the tube carrier plate 120, thereby causing a significant increase in frictional resistance and scratching of the tube surface.

In one specific example, the supporting mechanism 100 further includes a movable plate 140, the movable plate 140 is rotatably connected to one end of the tube supporting plate 120 in the extending direction, as shown in fig. 2, and the movable plate 140 is connected to the left end of the tube supporting plate 120. Specifically, the rotation axis between the movable plate 140 and the tube supporting plate 120 is perpendicular to the extending direction of the tube supporting plate 120, so that the movable plate 140 can rotate around the rotation axis. The first cylinder 150 is connected below the movable plate 140 for supporting the movable plate 140, and the first cylinder 150 is used for enabling the movable plate 140 to be connected to the tube loading plate 120 in parallel, or enabling one end of the movable plate 140 far away from the rotating shaft to rotate in a direction lower than the tube loading plate 120.

Specifically, the cylinder generally includes a rod and a cylinder body, and the rod is movable as a piston in the cylinder body and fixed at a start point or an end point. It can be understood that the rod of the first cylinder 150 can be extended or retracted, when the rod of the first cylinder 150 is extended, the support movable plate 140 is parallel to the tube carrying plate 120, and when the rod of the first cylinder 150 is retracted, the support movable plate 140 is inclined and one end is lower than the tube carrying plate 120. In the actual cutting of the tube, the laser cutting generates scraps, and the scraps may slide on the surface of the movable plate 140 along the extending direction (i.e., the tube length direction) by arranging the first cylinder 150 such that the movable plate 140 is inclined along the extending direction.

Optionally, the laser pipe cutting feeder further comprises a waste bin 500, wherein the waste bin 500 is disposed below one end of the pipe carrying plate 120 and is used for receiving waste sliding from the surface of the pipe carrying plate 120.

In one embodiment, the bearing mechanism 100 further includes a support 160, a movable link 170 and a second cylinder 180, the support 160 is disposed under the tube carrying plate 120, the support 160 is movably connected to the tube carrying plate 120 through the movable link 170, and the second cylinder 180 is connected between the support 160 and the tube carrying plate 120 for tilting the tube carrying plate 120 to a side parallel to the extending direction thereof.

It will be appreciated that the side of the tube carrying plate 120 can be raised or lowered in height as the rod of the second cylinder 180 extends from or retracts into the cylinder.

When one side of the tube loading plate 120 moves downwards, the distance between the side of the tube loading plate 120 and the limiting mechanism 300 is increased to form a gap which is enough for accommodating the tube to pass through, and the tube can slide down along the gap. Referring to fig. 6, the laser pipe cutting and blanking device further includes a skip 600. When the pipe cutting is completed, the pipe can be dropped into the skip 600 by controlling the operation of the second cylinder 180.

It should be understood that, for convenience of indicating the orientation of the tube carrier plate 120, "end" is used to describe two end points in the extending direction of the tube carrier plate 120, and "side" is used to describe two side edges parallel to the extending direction of the tube carrier plate 120.

The floating mechanism 200 is used to drive the tube loading plate 120 to move in a direction perpendicular to the plate surface, i.e. up and down according to the orientation shown in the figure. The floating mechanism 200 may include a motor and a vertically lifting cylinder driven by the motor, and one end of the cylinder is connected to the tube carrying plate 120 to drive the tube carrying plate 120 to move in a direction perpendicular to the plate surface. However, in order to make the entire tube loading plate 120 uniformly ascend or descend and further reduce the volume occupied by the floating mechanism 200, so that the entire laser tube cutting feeder can be installed in the existing laser cutting machine, the present embodiment provides another specific implementation manner. Specifically, in one specific example, the floating mechanism 200 includes a driving device 210 and a lifting frame 220, the driving device 210 is connected to the lifting frame 220, the lifting frame 220 is connected to the support 160, and the driving device 210 is used for driving the lifting frame 220 to move.

Further, please refer to fig. 3, which shows a specific structural diagram of the driving device 210. The driving device 210 at least includes a power member 211 and a transmission member 212 driven by the power member 211. The driving member 211 can drive the driving member 212 to reciprocate along a straight line, for example, along the extending direction of the tube loading plate 120. Specifically, the power member 211 may be a motor and the transmission member 212 may be a transmission rod. The power member 211 can drive the transmission member 212 to reciprocate through the first lead screw assembly 213.

Further, please refer to fig. 4, which shows a specific structural diagram of the lifting frame 220. The crane 220 is an X-type crane. The lifting frame 220 is connected with the transmission member 212, and the transmission member 212 pushes the lifting frame 220 to complete the lifting or descending action.

It will be appreciated that the X-crane is generally formed by two crossed turning handles and a connecting shaft. For example, as shown in fig. 4, the lifting frame 220 in the present embodiment includes a first turning handle 221, a second turning handle 222, and a connecting shaft 223 connecting the first turning handle 221 and the second turning handle 222.

The lifting frame 220 further comprises a first guide rail 224 and a first sliding block 225 arranged on the first guide rail 224, one end of the first rotating handle 221 is fixedly connected to the first sliding block 225, and the other end of the first rotating handle 221 is fixedly connected to the support 160.

Meanwhile, the lifting frame 220 further includes a second guide rail 226 and a second slider 227 disposed on the second guide rail 226, the second guide rail 226 is disposed under the tube loading plate 120 and connected to the support 160, one end of the second rotating handle 222 is connected to the second slider 227, and the other end is fixed, for example, fixed to the frame 400. To facilitate understanding of the specific connection relationship, the second guide rail 226 and the second slider 227 can be seen on the support 160 below the tube carrier plate 120 shown in fig. 2.

Thus, the lifting frame 220 can drive the tube loading plate 120 to lift by the driving member 212.

Specifically, the first rotation handle 221 includes two sub rotation handles respectively disposed at two sides of the second rotation handle 222, and a first beam and a second beam connecting the two sub rotation handles, which are respectively an upper beam and a lower beam as shown in fig. 4. The first beam is fixedly attached to support base 160 and the second beam is fixedly attached to drive member 212. The driving part 212 may push the second beam of the lifting frame 220 to make the lifting frame 220 perform a lifting motion, or pull the second beam of the lifting frame 220 back to make the lifting frame 220 perform a lowering motion. Alternatively, the transmission member 212 may be directly connected to the first slider 225 to be indirectly connected to the second beam, or may be directly connected to the second beam.

In a further specific example, there are a plurality of transmission members 212, a plurality of lifting frames 220 and the number of the lifting frames is the same as that of the transmission members 212, and the transmission members 212 are connected to the first sliding blocks 225 in the corresponding lifting frames 220. It is understood that there may be a plurality of power members 211, the number of which may be the same as that of the transmission members 212, or there may be only one power member 211, and the power members 211 drive the transmission members 212 to synchronously operate. In order to save space inside the device, please refer to fig. 1, which shows a specific example of only one power member 211 synchronously moving a plurality of transmission members 212. This power piece 211 is the motor, and the motor is whole to be fixed in on frame 400, and the motor has the toothed motor head that can rotate, and toothed motor head settles on toothed rail, and the motor head drives toothed rail motion when rotating, and toothed rail drives two first lead screw assembly 213 that are connected rather than the drive and changes the pivoted mode into rectilinear movement's mode to two driving medium 212 of synchronous promotion. In this example, the threads in the two first lead screw assemblies 213 rotate in opposite directions during this process.

Referring to fig. 5, a specific implementation of the limiting mechanism 300 is shown. Specifically, the limiting mechanism 30 includes a limiting member and a limiting member supporting arm 310, and the limiting member is connected to the limiting member supporting arm 310. The limiting member is located above the tube loading plate 120, and is used for limiting the swing of the processed tube.

The limiting member may be a baffle located above one side of the tube loading plate 120, and the baffle can sufficiently prevent the processed tube from generating significant side-to-side swinging. However, the contact area between the baffle and the processed pipe is large, and obvious friction force is easily generated between the baffle and the pipe in the processing process, so that the plate is scratched.

This embodiment further provides a specific limiting member, which includes two spacing rods 320, each of which is connected to the limiting support arm 310. The tubular product can be placed between two gag lever posts 320, and gag lever post 320 also can avoid the tubular product of processing to take place obvious horizontal hunting. In addition, the contact area between the limiting rod 320 and the pipe is extremely small, and even if the limiting rod is in contact with the pipe, the surface of the pipe cannot be obviously scratched.

Further, the limiting mechanism 300 further comprises an adjusting device, and the adjusting device is used for adjusting the distance between the two limiting rods 320, so as to be suitable for application scenes of pipes with various sizes and shapes. Specifically, adjusting device includes second lead screw assembly 330, and screw rod 330 connects on spacing support arm 310, and the one end of at least one gag lever post is connected in second lead screw assembly 330, and second lead screw assembly 330 is used for driving the gag lever post translation. It can be understood that when the second screw assembly 330 drives the limiting rods 320 to move horizontally, the distance between the two limiting rods 320 can be adjusted, and further the limiting rods 320 can be further applied, the second screw assembly 330 can simultaneously connect the two limiting rods through the two T-shaped blocks 340, one end of each limiting rod is connected to one end of the T-shaped block 340, the screw of the second screw assembly 330 is connected to the other end of the T-shaped block, and the two T-shaped blocks 340 are driven to be away from or close to each other by adjusting the screw of the second screw assembly 330, so as to adjust the distance between the two limiting rods. By the aid of the limiting device, the middle point between the two limiting rods is fixed, and accordingly the middle position of the processed pipe is fixed all the time.

Further, the present invention provides a laser cutting apparatus, comprising a laser cutting machine and a laser pipe cutter, wherein the laser pipe cutter is the laser pipe cutter according to any of the above embodiments.

The laser pipe cutting feeder can be used as follows: when the pipe needs to be cut by laser, a part of the long pipe can be placed on the pipe bearing plate 120, the pipe bearing plate 120 is driven to move up and down through a preset movement program of the floating mechanism 200, and meanwhile, the laser cutter is enabled to cut according to a preset cutting mode. It can be understood that the cutting can not only act on one place of the pipe, the pipe can translate or rotate, the position to be cut is moved to the laser beam to complete the cutting, at the moment, the pipe bearing plate 120 is correspondingly floated, the pipe can be ensured to be always attached to the rolling part 110 to move and rotate, the pipe does not swing to a large extent, the situation that the pipe is locally deformed obviously under the action of gravity can not be caused, the position of the pipe to be cut can not deviate obviously, and the precision of the laser cutting is ensured.

The pipe material loading plate capable of floating up and down is designed on the laser pipe cutting feeder, the pipe material always clings to the rolling piece to rotate in the actual cutting process, the large-amplitude swing of the pipe material is avoided, and the position precision of laser cutting in the pipe material cutting process is ensured. Meanwhile, the floating pipe bearing plate is matched with a limiting mechanism, so that the floating pipe bearing plate can be suitable for round pipes, square pipes, rectangular pipes and various special pipes, and the universality is strong. Furthermore, the rolling piece with the top protruding out of the upper surface is further installed in the pipe bearing plate, so that the pipe is prevented from being scratched due to translation or rotation of the pipe bearing plate floating up and down in the actual cutting process, and the processing quality of the pipe is guaranteed.

It should be understood that the above-mentioned embodiment is only one of the best possible modes of the present invention, and the size, position, shape, etc. of the components are set accordingly to realize the technical idea of the present invention, and the present invention is not limited to be realized only by the above-mentioned embodiment.
