Description

Technical Field

[0001] The utility model relates to the technical field of paper tray machines, in particular to a non-stop paper tray conveying 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] Since paper trays are thin products, they usually need to be stacked in a specified number before packaging. The existing stacking method usually uses manual stacking or a dedicated conveying device for stacking and conveying. The manual stacking method has low work efficiency. The paper tray stacking of the existing conveying device is pushed out by a cylinder, which is easy to jam the paper tray. The paper tray is easy to flip over when pushed to the conveyor belt, resulting in uneven stacking. Summary of the Invention

[0018] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1-3 As shown, a non-stop paper tray conveying device includes a frame 1, and a first conveyor belt 2 and a second conveyor belt 3 are provided on the frame 1. The first conveyor belt 2 is arranged above the second conveyor belt 3, and a storage space 11 is formed between the first conveyor belt 2 and the second conveyor belt 3. A supporting mechanism 6 is provided below the second conveyor belt 3. The supporting mechanism 6 includes a support plate 21 and a driving mechanism for driving the support plate to move up and down. The storage space 11 is provided with a material baffle plate 4 near the first conveyor belt 2, and a first driving cylinder 41 for driving the material baffle plate 4 to move horizontally is provided on the side of the material baffle plate 4.

[0020] The conveying device can be directly combined with the paper tray machine to form an assembly line. The working process is as follows: the paper tray pressed and formed by the paper tray machine is transported from the starting end of the first conveyor belt 2, and the driving mechanism drives the support plate 21 to rise, and makes the support plate 21 support the paper tray transported by the first conveyor belt 2. As the paper trays are stacked, the support plate 21 gradually descends so that the plane of the top end receiving the paper tray remains unchanged, ensuring that the paper tray will not turn over due to the large drop of the first conveyor belt 2, ensuring the neatness of the paper tray stacking. When the paper trays are stacked to the specified number, the first driving cylinder 41 drives The baffle plate 4 moves laterally and acts as a temporary block. Since the baffle plate 4 is close to the first conveyor belt 2, the paper tray will not flip over when it falls on the baffle plate 4. The support plate 21 descends to make the stacked paper tray fall on the second conveyor belt 3 and be conveyed to the subsequent packaging step via the second conveyor belt 3. Then the support plate 21 rises and the baffle plate 4 moves laterally and no longer supports the paper tray. The paper tray originally temporarily supported by the baffle plate 4 falls on the support plate 21, realizing non-stop feeding, smooth paper tray transportation, neat stacking, high degree of automation and high work efficiency.

[0021] In this embodiment, the second conveyor belt 3 is a plurality of parallel conveyor belts with a certain distance between them, and there are a plurality of pallets 21. The pallets 21 can move from between the parallel conveyor belts from the bottom of the second conveyor belt 3 to the top of the second conveyor belt 3 to support the paper tray, so that the center position of the pallet 21 and the center position of the second conveyor belt are located on the same axis, ensuring that the paper tray will not be offset when it falls on the second conveyor belt 3, and the transportation is stable.

[0022] In this embodiment, the drive mechanism includes a fixed plate 23 and a driving member that drives the fixed plate up and down. The support plate 21 is fixed to the fixed plate 23 via connecting posts 22. The driving member is an electric push rod 27 or a servo cylinder 26. The electric push rod 27 or servo cylinder 26 operates with low noise and smooth motion. Furthermore, the fixed plate 23 is provided with a number of guide posts 25. The frame 1 is provided with a number of guide holes 24 corresponding to the guide posts 25. The guide posts 25 are inserted into the guide holes 24. The guide posts 25 and the guide holes 24 cooperate to guide the up and down movement of the support plate 21, preventing it from deflecting and ensuring the stability of the supporting paper tray.

[0023] In this embodiment, the storage space 11 is provided with a paper-beating assembly, including a push plate 5, a paper-blocking column 8, and a shaking cylinder 51. The shaking cylinder 51 drives the push plate 5 to perform a reciprocating beating action to slap the stacked paper trays neatly. The distance between the push plate 5 and the paper-blocking column 8 is adjustable. The storage space 11 is provided with two baffles 7 to prevent the paper tray from offsetting when it moves downward. The two baffles 7 are arranged on both sides of the second conveyor belt with an adjustable distance to accommodate paper trays of different sizes.

[0024] In this embodiment, a blocking piece 9 is provided above the first conveyor belt 2. The blocking piece 9 is arranged to be tilted downward from the conveying direction of the paper tray to ensure that the paper tray will not turn over during conveyance.

[0025] 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.
