Technical Field

[0001] This utility model belongs to the technical field of laser cutting machine equipment and relates to an automatic feeding device for laser cutting machines. Background Technology

[0002] Pipe cutting equipment is a specialized device used to cut pipes. Traditional pipe cutting equipment mostly uses a mechanical structure to drive the cutting tool to cut the pipe. In this type of structure, workers are often required to assist in the pipe cutting operation. This results in high labor intensity for workers, low pipe cutting efficiency, and certain dangers, and it is no longer able to meet the production needs of modern fast and automated pipe cutting.

[0003] For example, patent application publication number CN113878247A discloses a laser pipe cutting device with a frame. Its features include: a pipe conveyor belt assembly on one side of the frame; a lifting platform at the discharge end of the conveyor belt assembly; the lifting platform connected to a linkage drive assembly; a rotatable first clamping head assembly in front of the lifting platform, connected to a first horizontal drive assembly; a second clamping head assembly behind the lifting platform; a laser cutter near the second clamping head assembly; and a receiving platform below the laser cutter. This invention has a simple structure and reasonable design, enabling efficient and fully automatic laser cutting of various specifications and shapes of pipes.

[0004] However, in the above scheme, the device requires manual loading after cutting, which increases the labor force. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an automatic feeding device for laser cutting machines.

[0006] The objective of this utility model can be achieved through the following technical solution: an automatic feeding device for a laser cutting machine, comprising a feeding rack, a transmission chain for conveying pipes on the feeding rack, a plurality of evenly distributed partitions on the transmission chain, a placement groove for accommodating pipes formed between every two partitions, a driving component for driving the transmission chain to rotate on the feeding rack, a receiving component at the rear end of the feeding rack, the receiving component comprising a receiving plate, a driving cylinder for controlling the height of the receiving plate at the bottom of the receiving plate, and a feeding component at the rear end of the receiving plate.

[0007] In the aforementioned automatic feeding device for a laser cutting machine, the receiving plate includes a flat plate and an inclined plate that tilts upward toward the transmission chain, and a baffle is also provided on the other side of the flat plate.

[0008] In the aforementioned automatic feeding device for a laser cutting machine, the driving component includes a rotating wheel, the transmission chain is connected to the transmission wheels at both ends, the feeding frame is also provided with a synchronous transmission shaft, the synchronous transmission shaft is connected to the rotating wheels on multiple feeding frames, and a drive motor is provided at one end of the synchronous transmission shaft.

[0009] In the aforementioned automatic feeding device for a laser cutting machine, the feeding assembly includes a sliding frame, on which a horizontally slidable mounting block is provided, and on which a three-jaw clamp for gripping the pipe is provided, and a horizontal cylinder for driving the mounting block to slide is provided on one side of the feeding frame, and the three-jaw clamp is arranged in a straight line with the plate.

[0010] In the aforementioned automatic feeding device for a laser cutting machine, the top of the sliding frame is provided with a sliding groove, which is dovetail-shaped, and the bottom of the mounting block matches the sliding groove. The mounting block slides along the dovetail groove and is pushed by a horizontal cylinder. The three-jaw clamp accurately feeds the pipe into the laser cutting machine after gripping it.

[0011] Compared with existing technologies, this utility model uses an automatic feeding method to replace manual feeding, achieving continuous feeding and greatly improving production efficiency. Attached Figure Description

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example

[0016] like Figure 1 and Figure 2As shown, an automatic feeding device for a laser cutting machine includes a feeding rack 1, on which a transmission chain 2 for conveying pipes is provided. The transmission chain 2 is provided with a plurality of evenly distributed partitions 3, and a placement groove 4 for accommodating pipes is formed between every two partitions 3. The feeding rack 1 is provided with a drive assembly 5 for driving the transmission chain 2 to rotate. The rear end of the feeding rack 1 is provided with a receiving assembly 6, which includes a receiving plate 61. A drive cylinder 62 for controlling the height of the receiving plate 61 is provided at the bottom of the receiving plate 61.

[0017] The receiving plate 61 has a feeding assembly 7 at its rear end. The feeding assembly 7 includes a sliding frame 71, on which a horizontally slidable mounting block 72 is mounted. The mounting block 72 is equipped with a three-jaw clamp 73 for gripping the pipe. In this embodiment, the pipe can be round or square, and the three-jaw clamp 73 can clamp the pipe in either case. A horizontal cylinder 74 is provided on one side of the feeding frame 1 to drive the mounting block 72 to slide. The three-jaw clamp 73 is aligned with the plate 612. A sliding groove 8 is provided at the top of the sliding frame 71. The sliding groove 8 is dovetail-shaped. The bottom of the mounting block 72 matches the sliding groove 8. The mounting block 72 slides along the dovetail groove and is pushed by the horizontal cylinder 74. After gripping the pipe, the three-jaw clamp 73 accurately feeds it into the laser cutting machine.

[0018] The receiving plate 61 includes a flat plate 612 and an inclined plate 611 that tilts upward toward the transmission chain 2. A baffle 613 is also provided on the other side of the flat plate 612 to block the pipe after it falls.

[0019] The drive assembly 5 includes a rotating wheel 51, the transmission chain 2 is connected to the transmission wheels at both ends, the feeding rack 1 is also provided with a synchronous transmission shaft 52, the synchronous transmission shaft 52 is connected to the rotating wheels 51 on multiple feeding racks 1, and a drive motor 53 is provided at one end of the synchronous transmission shaft 52.

[0020] Working principle: Start the drive motor 53. The drive motor 53 rotates and drives the synchronous transmission shaft 52 to rotate, which in turn drives the transmission wheel to rotate, thereby driving the transmission chain 2 to rotate and convey the pipe forward. When the partition block 3 on the transmission chain rotates to the arc surface of the rotating wheel 51, the pipe falls from the placement groove 4 onto the receiving plate 61. Then the drive cylinder 62 lifts the pipe upward to the same height as the three-jaw clamp 73. Then the horizontal cylinder 74 drives the feeding block 72 to move towards the pipe so that the three-jaw clamp 73 clamps the pipe. After that, the drive cylinder 62 drives the receiving plate 61 to descend. Then the horizontal cylinder 74 continues to drive the pipe to the rear laser cutting machine for processing and cutting.

[0021] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
