Description

Technical Field

[0001] The present application relates to the technical field of automatic feeding, and in particular to an automatic feeding device for CNC cutting equipment. Background Art

[0002] Mechatronic cutting machines are called CNC cutting machines. They are driven by digital programs. As the machine moves, the cutting tools that come with it cut the object.

[0003] The traditional method of feeding pipes for CNC cutting is manual feeding, which is time-consuming, labor-intensive and inefficient. It usually requires two people to lift the materials and place them on the supporting parts of the CNC cutting equipment. Safety hazards may arise during the feeding process, and it is difficult to unify the manual feeding height. Sometimes the materials are too heavy, and the operators will involuntarily want to release the materials quickly, which increases the impact load of the main bed. Therefore, the above problems need to be solved urgently. Summary of the invention

[0023] The telescopic cylinder is fixedly installed below the guide plate and is located on a side close to the material discharge mechanism. The piston rod can extend to the top of the guide plate to limit the passage of the pipe.

[0024] Furthermore,

[0025] The sprocket is driven by a stepper motor;

[0026] The guide plate is provided with a limit switch linked to the stepping motor;

[0048] In this embodiment, the top of the frame 100 is rectangular, with the length direction being the first direction and the width direction being the second direction; at the same time, an inclined guide plate 110 is also provided on the top of the frame 100 to guide the pipe output by the loading mechanism along the second direction to the discharge mechanism, and then the pipe is transported to the CNC cutting machine through the discharge mechanism.

[0049] In this embodiment, the storage rack 200 includes a base plate fixedly mounted on the frame body 100 and columns vertically mounted on the base plate; the base plate and the frame body 100 are installed at an angle, and the height of the side close to the frame body 100 is relatively low, so that the pipe can automatically move to the side close to the frame body 100 by gravity; the column is located on the side of the base plate away from the frame body 100, and the storage rack 200 is formed between the base plate and the frame body 100.

[0050] In this embodiment, a paddle 210 is installed on the frame 100 through a chain 220; the paddle 210 extends into the storage rack 200, and the pipes in the storage rack 200 can be effectively lifted onto the guide plate 110 by the drive of the chain 220.

[0051] When the pipe is output through the guide plate 110, the docking block 310 first slides to the end of the base frame 300 close to the frame 100, and then rises to dock with the guide plate 110, thereby lifting the output pipe; then the docking block 310 can move the pipe to the side away from the frame 100 by sliding; and the descent of the docking block 310 can make the pipe dock with the docking plate 320, thereby detaching from the docking block 310, so that the pipe can roll onto the CNC cutting machine through the docking plate 320. In this process, since the slope of the docking plate 320 is relatively gentle and there is no height difference between the docking plate 320 and the CNC cutting machine, the pipe can complete automatic loading without causing impact on the CNC cutting machine.

[0056] In a preferred embodiment, the sprocket 120 is driven by a stepper motor; a limit switch linked to the stepper motor is provided on the guide plate 110; the limit switch is installed at the telescopic cylinder 111, and is used to detect whether there is a pipe on the guide plate 110 and control the start and stop of the stepper motor.

[0057] In this embodiment, the sprocket 120 is driven by a stepper motor, and the stepper motor is also linked to a limit switch; the triggering of the limit switch by the pipe can effectively control the start and stop of the stepper motor.
