Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0027] A double-layer roller conveyor line comprises a first roller conveyor 1, wherein four corners of the upper end of the first roller conveyor 1 are provided with support legs 2, a second roller conveyor 3 is fixedly installed at the top of the four support legs 2, a third roller conveyor 4 is movably installed on one side of the first roller conveyor 1 and the second roller conveyor 3; a support frame 5, wherein the support frame 5 is fixedly installed at both ends of one side of the second roller conveyor 3, a frame 6 is fixedly installed on the same side of the two support frames 5 and the first roller conveyor 1, and a screw rod 7 is movably installed in the middle of both sides of the frame 6; a lifting frame 8, wherein the lifting frame 8 is fixedly installed at both ends of the second roller conveyor 3, and the lifting frame 8 is fixedly installed at both ends of the second roller conveyor 3. The two ends of the lowering frame 8 are respectively threadedly connected to the two screw rods 7, and the two sides of the third roller conveyor 4 are respectively fixedly connected to the two lifting frames 8; a transmission housing 9 is fixedly installed between the tops of the frames 6, and a servo motor 10 is fixedly installed on the top of one side of the transmission housing 9. The tops of the two screw rods 7 are located inside the transmission housing 9, and pulleys 11 are arranged at one end, and the two pulleys 11 are movably connected through belts. The output shaft of the servo motor 10 is fixedly connected to any one of the pulleys 11; guide rods 12 are arranged at the four corners of the frame 6, and the two ends of the lifting frame 8 are movably connected with the guide rods 12;

[0028] In this embodiment, when it is necessary to switch the transportation of articles between the first roller conveyor 1 and the second roller conveyor 3, the servo motor 10 is started, and the servo motor 10 drives the screw rod 7 to rotate through the pulley 11 and the belt transmission, and the screw rod 7 controls the lifting frame 8 to rise and fall, and the lifting frame 8 drives the third roller conveyor 4 to rise and fall synchronously when it rises and falls. For example, when the articles move on the second roller conveyor 3, the third roller conveyor 4 is adjusted to be level with the third roller conveyor 4 until the articles are translated from the second roller conveyor 3 to the third roller conveyor 4, and then the third roller conveyor 4 is controlled to fall and keep level with the first roller conveyor 1, and then the articles are transferred from the third roller conveyor 4 to the first roller conveyor 1;

[0029] Furthermore, if other conveyor lines of different heights are arranged on one side of the first roller conveyor 1 and the second roller conveyor 3, the position of the third roller conveyor 4 can be adjusted according to the heights of the other conveyor lines, so that the items entering the third roller conveyor 4 from the first roller conveyor 1 and the second roller conveyor 3 can be transferred to other conveyor lines through the third roller conveyor 4.

[0030] like Figure 3 As shown, a mounting frame 13 is fixedly installed between the top ends of the two support frames 5, an electric push rod 14 is fixedly installed in the middle of the top end of the mounting frame 13, and the output shaft of the electric push rod 14 passes through the mounting frame 13 and is fixedly installed with a baffle 15; movable rods 16 are fixedly installed on both sides of the top end of the baffle 15, and the two movable rods 16 are movably connected to the mounting frame 13;

[0031] In this embodiment, when an article enters the third roller conveyor 4 from the second roller conveyor 3, the electric push rod 14 at the top of the mounting frame 13 is started. After the electric push rod 14 is started, the baffle 15 is controlled to drop straight down, so that the end of the second roller conveyor 3 close to the third roller conveyor 4 can be blocked to prevent the article from falling from the second roller conveyor 3, thereby achieving the purpose of facilitating protection.

[0032] like Figure 1 As shown, the height of the support frame 5 is equal to the support leg 2;

[0033] In this embodiment, since the height of the support frame 5 is equal to that of the support leg 2, the objects will not cause interference when being transferred.

[0034] Working principle: When it is necessary to switch the transportation of items between the first roller conveyor 1 and the second roller conveyor 3, start the servo motor 10, and the servo motor 10 drives the screw rod 7 to rotate through the pulley 11 and the belt transmission. The screw rod 7 controls the lifting and lowering of the lifting frame 8, and the lifting and lowering of the lifting frame 8 drives the third roller conveyor 4 to be lifted and lowered synchronously. For example, when the items move on the second roller conveyor 3, the third roller conveyor 4 is adjusted to be level with the third roller conveyor 4 until the items are translated from the second roller conveyor 3 to the third roller conveyor 4, and then the third roller conveyor 4 is controlled to fall and keep level with the first roller conveyor 1, and then the items are transferred from the third roller conveyor 4 to the first roller conveyor 1.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
