The same conveyor belt 52 is drivingly connected between the two conveyor rollers 51, and the conveyor belt 52 is in a state of being lower on the left and higher on the right. A plurality of strip-shaped blocks 53 arranged in parallel are fixedly installed at equal intervals on the side of the conveyor belt 52 away from the conveyor roller 51, which can convey the pipes to be bent. The hydraulic cylinder 31 is fixedly installed on the top of the support frame 3, the bending block 32 is fixedly installed on the working end of the hydraulic cylinder 31, the lifting plate 4 is fixedly installed on the working end of the hydraulic cylinder 31. Both support seats 33 are fixedly installed on the bottom inner wall of the support frame 3 and are adapted to the conveyor belt 52. A toothed disc 61 is rotatably installed on the rear inner wall of the support frame 3 with the right rotating shaft 5 as the center. A ratchet wheel 62 is fixedly sleeved on the right rotating shaft 5. A pawl 63 is hingedly installed on the inner wall of the toothed disc 61. The same spring 64 is fixedly installed between the pawl 63 and the inner wall of the toothed disc 61, and the pawl 63 is adapted to the ratchet wheel 62. A toothed plate 6 is fixedly installed on the bottom side of the lifting plate 4 away from the strip-shaped plate 7. The toothed plate 6 meshes with the toothed disc 61, which can control the right rotating shaft 5 to rotate clockwise when the lifting plate 4 moves upward, so as to realize the automatic feeding of the pipes. At the same time, it can keep the rotating shaft 5 stationary when the lifting plate 4 moves downward, so as to realize the one-way conveying operation of the conveyor belt 52. A strip-shaped plate 7 is fixedly installed at one end of the bottom side of the lifting plate 4 away from the conveyor roller 51. A discharge plate 71 is fixedly installed at the bottom of one side of the strip-shaped plate 7. The discharge plate 71 is located between the two support seats 33 and is arranged in a state of being higher on the left and lower on the right, which can unload the bent pipe fittings on the support seats 33 from the support seats 33 as the lifting plate 4 rises.

[0035] Specifically, in order to guide the pipes to be bent conveyed on the conveyor belt 52 to the two support seats 33, the same guide plate 331 is fixedly installed on the two support seats 33, and the guide plate 331 is arranged in a state of being higher on the left and lower on the right.

[0036] Specifically, in order to provide stable support for the right rotating shaft 5 and ensure the stable operation of the rotating shaft 5, the conveyor roller 51 and the conveyor belt 52, a support plate 301 is fixedly installed on the bottom inner wall of the support frame 3, and the right rotating shaft 5 is rotatably connected with the support plate 301 with damping.

[0037] Specifically, in order to guide the lifting plate 4 and ensure the stable lifting of the lifting plate 4, a plurality of guide rods 41 are fixedly installed on the top inner wall of the support frame 3, and the plurality of guide rods 41 are all slidably connected with the lifting plate 4.

[0038] Specifically, in order to limit the lifting range of the lifting plate 4 and ensure that the lifting plate 4 does not lose contact with the guide rod 41 , a limiting block 42 is fixedly installed at the bottom end of the guide rod 41 .

[0039] Specifically, in order to facilitate the placement of the pipes to be bent into the material box 2 and enable the pipes to be bent to automatically move to a position close to the discharge port, the top of the material box 2 is open and the bottom inner wall of the material box 2 is higher on the left and lower on the right, thereby ensuring the continuity of feeding.

[0040] Working principle: When in use, first turn on the power and place the pipe to be bent in the material box 2, then the pipe automatically moves to a position close to the discharge port under the action of gravity. When the pipe moves to the discharge port, the pipe falls on the conveyor belt 52, and then the hydraulic cylinder 31 is started. The working end of the hydraulic cylinder 31 drives the lifting plate 4, the strip plate 7 and the discharge plate 71 to move upward. At this time, the tooth plate 6 controls the rotation of the right shaft 5 through the cooperation of the toothed disc 61, the pawl 63, the ratchet 62 and the spring 64, so that the conveyor belt 53 can transport the pipe from the discharge port to the upper right, and as the hydraulic cylinder 31 continues to rise, the lifting plate 4, the strip plate 7 and the discharge plate 71 are driven by the hydraulic cylinder 31. The lowering operation can control the conveying device 52 to carry out intermittent conveying of the pipe, so as to achieve the purpose of automatic loading. The pipe stably follows the conveyor belt 52 to move to the upper right under the action of it 53, and falls on the two support seats 33 under the action of the guide plate 331. Then, the bending operation of the pipe is completed when the hydraulic cylinder 31 controls the bending block 32 to move downward. As the hydraulic cylinder 31 controls the bending block 32 to move upward, the lifting plate synchronously carries the strip plate 7 upward, and the unloading plate 71 removes the bent pipe from the support seat 33, thereby completing automatic unloading, and then effectively improving work efficiency.

[0041] The above is a detailed introduction to the automatic feeding platform of a pipe bending machine provided by the utility model. This article uses specific embodiments to explain the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
