Description

Technical Field

[0001] The utility model relates to the technical field of paper tray machines, in particular to a rotary paper tray feeding device. Background Art

[0002] A paper plate is a paper container made from cardboard made from chemical wood pulp or non-wood plant fibers, pressed through a rolling mill. While similar in appearance to other porcelain plates, they are significantly lighter. They can be used to hold Western dishes, as well as bread, cakes, and snacks.

[0003] Paper tray forming often requires multiple working steps, and the use of a linear assembly line may cause the paper tray machine to occupy too much space. Therefore, a rotary feeding device is usually used to rotate the paper tray from the main conveyor belt to the side of the main conveyor belt for oiling, creasing, etc. Since paper trays are thin products, suction nozzles are usually used for material transfer, and the suction nozzles require an air source. When the suction nozzles rotate, the corresponding air pipes are easily entangled, affecting use. Summary of the Invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural schematic diagram of an embodiment of the present utility model. DETAILED DESCRIPTION

[0015] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1 As shown, a rotary paper tray feeding device includes a frame 1, a rotating motor 3, a rotating shaft 21, and a turntable 2. The rotating motor 3 is arranged below the frame 1. The lower end of the rotating shaft 21 is connected to the output end of the rotating motor 3. The turntable 2 is sleeved on the rotating shaft 21 and rotates with the rotating shaft 21. Suction assemblies are symmetrically arranged at both ends of the turntable 2. The upper end of the rotating shaft 21 is provided with a mounting bracket for an air pipe that provides an air source for the suction assembly. The mounting bracket includes a fixed part 10 and a rotating part 11. The side of the fixed part 10 is provided with a plurality of air inlet holes for connecting to the air inlet pipe. The side of the rotating part 11 is provided with a plurality of air outlet holes for connecting the air outlet pipe, and the air inlet hole is connected to the air outlet hole through the middle cavity 12. The fixed part 11 is fixed to the upper end of the rotating shaft 21. A bearing can be provided between the fixed part 11 and the rotating shaft 21 to prevent the fixed part 11 from rotating with the rotating shaft 21. The rotating part 11 rotates coaxially with the rotating shaft 21. When the rotating shaft 21 rotates, the turntable, the suction component provided on the turntable, the rotating part, and the air pipe connected to the suction component and the rotating part rotate synchronously, which can effectively avoid the air pipe from being entangled and ensure stable feeding.

[0017] In this embodiment, a lifting mechanism is provided below the turntable 2 to drive the turntable 2 up and down. The lifting mechanism includes a lifting cylinder 6 and a push rod 61. The upper end of the push rod 61 presses against the lower end of the turntable 2. During the material transfer process, the turntable 2 moves downward to more conveniently and easily pick up the paper tray, which reduces the amount of air required to be transmitted to the air pipe, effectively reducing noise. Furthermore, a first fixing plate 4 is provided above the turntable 2, and a second fixing plate 5 is provided below the turntable 2. The turntable 2 is provided with a guide hole 7, and a guide post 8 is inserted into the guide hole 7. The upper end of the guide post 8 is fixed to the first fixing plate 4, and the lower end is fixed to the second fixing plate 5, ensuring that the turntable 2 does not deviate during its up and down movement.

[0018] In this embodiment, the material suction assembly includes an extension plate 9, one end of which extends outside the turntable. The end of the extension plate 9 extending outside the turntable is provided with a suction nozzle 13. The air pipe of the suction nozzle 13 is connected to the rotating part 10. By controlling the air volume, it is convenient to suck or release the paper tray. Preferably, two or more suction nozzles 13 are arranged in an array so that they can be evenly applied force when sucking the paper tray to prevent deviation. Furthermore, the end of the extension plate 9 extending outside the turntable is provided with a stabilizing cardboard 14. The middle of the stabilizing cardboard 14 is provided with a through hole for the suction nozzle 13 to pass through. The stabilizing cardboard 14 can further prevent the paper tray from tilting and ensure stable material transfer. The stabilizing cardboard 14 is detachably connected to the extension plate 9, and the appropriate size of the stabilizing cardboard 14 can be selected according to the actual size of the paper tray.

[0019] A driving mechanism for driving the extension plate 9 to move laterally is provided at the lower end of the extension plate 9. The driving mechanism includes a slider 15, a guide rail 16, and a driving cylinder 17. The slider 15 is sleeved on the guide rail 16 and the upper end is fixed to the extension plate 9. The driving cylinder 17 drives the slider 15 to move laterally along the guide rail 16. The air pipe of the driving cylinder 28 is connected to the rotating part 10. The driving mechanism enables the extension plate 9 to be extended laterally for a longer distance, which is convenient and flexible.

[0020] The embodiments should not be regarded as limiting the present invention, and any non-inventive improvements based on the spirit of the present invention should be regarded as falling within the protection scope of the present invention.
