DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The purpose of the present invention is to provide an automatic feeding and lifting device for plastic pipes and a method for using the device to solve the problems existing in the prior art. The device can automatically lift the plastic pipes transferred from the previous process to a high place for storage, and can avoid the accumulation of plastic pipes in the next process, thereby realizing mechanized and automated production and significantly improving production efficiency.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-Figure 3 As shown, this embodiment provides a plastic pipe automatic feeding and lifting device, including a lifting mechanism 1, a guide mechanism 2, a pushing mechanism 3 and a controller;

[0030] The lifting mechanism 1 comprises a lifting frame 4, on which a conveyor belt device 5 is provided, and on which a plurality of flaps 6 are provided at intervals;

[0031] The guide mechanism 2 is arranged between the lifting mechanism 1 and the pushing mechanism 3. The guide mechanism 2 includes a guide frame 7. A rotating shaft 8 is rotatably connected to the guide frame 7. The rotating shaft 8 is driven to rotate by a rotating driving device 9. A guide plate 10 is fixedly arranged on the rotating shaft 8. When the rotating shaft 8 rotates to the guide plate 10 and is in a first position, the guide plate 10 is used to guide the plastic pipe 11 to the flap 6. When the rotating shaft 8 rotates to the guide plate 10 and is in a second position, the guide plate 10 is used to guide the plastic pipe 11 to the ground. A plastic pipe monitoring sensor is arranged on the vertical frame of the conveyor belt device 5 at a height corresponding to the first position, which is used to perform real-time detection of the plastic pipe 11 after the plastic pipe 11 slides down onto the flap 6 through the guide plate 10. The plastic pipe monitoring sensor can be set as a photoelectric sensor.

[0032] The pushing mechanism 3 includes a pushing frame 12, on which a pushing support platform 13 is fixedly provided, and a push plate 14 is provided on the side of the pushing support platform 13 facing away from the guide mechanism 2, and the push plate 14 is connected to a linear drive device 15, and is used to push the plastic tube 11 on the pushing support platform 13 to the guide plate 10, and a baffle 16 is provided at one end of the pushing support platform 13, and a grating sensor 17 is provided on the baffle 16;

[0033] The conveyor belt device 5, the rotary drive device 9, the linear drive device 15, the plastic pipe monitoring sensor and the grating sensor 17 are all connected to the controller.

[0034] Under the control of the controller, the plastic tube 11 can be pushed to the guide plate 10 through the grating sensor 17 and the push plate 14. When the guide plate 10 is in the first position, the plastic tube 11 is guided by the guide plate 10 and slides onto the flap 6 on the conveyor belt. Then, under the monitoring feedback of the plastic tube monitoring sensor, the controller controls the conveyor belt device 5 to transport and transfer the plastic tube 11 to the next process for storage. When the guide plate 10 is in the second position, the plastic tube 11 pushed onto the guide plate 10 slides down along the guide plate 10 and falls to the ground. It will not continue to be transmitted to the next process, thus avoiding the accumulation of plastic tubes in the next process, realizing mechanized and automated production, saving labor costs, and significantly improving production efficiency.

[0035] In this embodiment, a plurality of conveyor belt devices 5 are arranged at intervals in the horizontal direction on the lifting frame 4, and the pulley driving shafts of each conveyor belt device 5 are connected through a synchronous shaft 18. Specifically, four conveyor belt devices 5 are provided. A driven sprocket is fixedly provided on the pulley driving shaft of one of the conveyor belt devices 5, and a driving motor 19 is fixedly installed on the lifting frame 4. A driving sprocket is fixedly provided on the output shaft of the driving motor 19, and the driving sprocket is connected to the driven sprocket through a chain. The pulley driving shaft of the conveyor belt device 5 is driven to rotate by the driving motor 19, and the pulley driving shafts of other driven conveyor belt devices 5 are driven to rotate synchronously through the synchronous shaft 18, ensuring that the four conveyor belts have the same operating speed to realize the transportation and lifting of the plastic pipe 11.

[0036] In this embodiment, the rotary drive device 9 is a rotary cylinder, the linear drive device 15 is a linear cylinder, and the conveyor belt device 5 is a chain conveyor belt.

[0037] In this embodiment, the guide plate 10 and the conveyor belt device 5 are arranged alternately to avoid interference between the guide plate 10 and the conveyor belt device 5 when the guide plate 10 is in the first position.

[0038] The method of using the automatic plastic pipe feeding and lifting device in this embodiment is as follows:

[0039] During normal production, the guide plate 10 is in the first position. When the plastic tube 11 is transferred to the push support platform 13 and one end of the plastic tube 11 is against the baffle 16, the grating sensor 17 detects the signal of the plastic tube 11 and transmits it to the controller. The controller controls the linear cylinder (linear drive device 15) to push the push plate 14 to move, and the plastic tube 11 is pushed to the guide plate 10; the plastic tube 11 slides down along the guide plate 10 to the flap 6, and the plastic tube monitoring sensor detects the signal of the plastic tube 11 and transmits it to the controller. The controller controls the conveyor belt device 5 to operate (that is, controls the drive motor 19 to operate), and the plastic tube 11 is transported and transferred to the next process for storage;

[0040] When the next process does not need to continue to convey the plastic pipe 11 and the previous process cannot stop production immediately, the controller controls the rotating cylinder (rotating drive device 9) to rotate the guide plate 10 to the second position. The second position can be a position where the guide plate 10 is perpendicular to the ground. The plastic pipe 11 pushed onto the guide plate 10 slides down along the guide plate 10 and falls to the ground and will not continue to be conveyed to the next process, thereby avoiding the accumulation of plastic pipes in the next process.

[0041] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
