Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a double-layer elevator. Background Technology

[0002] Vacuum insulation panels are a new type of high-efficiency insulation material based on the principle of vacuum insulation. They combine the advantages of vacuum insulation, microporous insulation and multilayer insulation, thus having outstanding insulation effect.

[0003] In the fabrication of vacuum insulation panels, the bottom shell and core material are placed on a heating frame on a tray. A barrier film is then placed on top of the core material, and the entire assembly is pushed into a vacuum chamber for vacuuming. Next, the barrier film and bottom shell are heat-sealed together. After the vacuum is broken, the tray is pulled out of the vacuum chamber, and finally, the vacuum insulation panel is removed from the heating frame, thus completing the fabrication of the vacuum insulation panel. Conveying rollers are used for both pushing and pulling the tray into and out of the vacuum chamber. Existing conveying rollers are typically single-layered, and the tray's insertion and removal rely entirely on this single roller, resulting in low efficiency. Utility Model Content

The conveying mechanism 2 includes a first mounting plate 21, a second mounting plate 22, an upper roller 23, and a lower roller 24. The first mounting plate 21 is fixed to one side of the lifting frame 1, and the second mounting plate 22 is fixed to the other side of the lifting frame 1. One end of the upper roller 23 is rotatably mounted on the first mounting plate 21, and the other end of the upper roller 23 is rotatably mounted on the second mounting plate 22. One end of the lower roller 24 is rotatably mounted on the first mounting plate 21, and the other end of the lower roller 24 is rotatably mounted on the second mounting plate 22. The lower roller 24 is located below the upper roller 23. The lifting mechanism 3 is located at the bottom of the lifting frame 1 to lift or lower the lifting frame 1. The distance by which the lifting frame 1 is lifted or lowered is equal to the distance between the lower roller 24 and the upper roller 23.

[0025] Thus, the double-layer lifting machine of this utility model is used by connecting the end of the double-layer lifting machine to a vacuum device, so that the upper roller 23 is flush with the inlet and outlet of the vacuum device. When the vacuum device is used to make a vacuum insulation panel and a tray needs to be output, the tray can be conveyed to the upper roller 23, and the upper roller 23 rotates to output the tray. Before this, the next tray can be pre-conveyed onto the lower roller 24. After the upper roller 23 rotates to output the previous tray, the lifting mechanism 3 drives the lifting frame 1 to rise, so that the lower roller 24 is flush with the inlet and outlet of the vacuum device. The lower roller 24 rotates to input the next tray into the vacuum device. Finally, the lifting mechanism 3 drives the lifting frame 1 to fall, so that the upper roller 23 is flush with the inlet and outlet of the vacuum device again. In this way, by setting the upper roller 23 and the lower roller 24 to be height-adjustable, the output of the previous tray and the input of the next tray can be seamlessly connected, thereby improving efficiency.

[0026] Optionally, a first base 11 is provided on one side of the lifting frame 1. A first drive mechanism 12 is provided on the first base 11 to drive the upper roller 23 to rotate.

The first right connecting seat 43 is fixed to the second mounting plate 22. The first right guide wheel 44 is rotatably mounted on the first right connecting seat 43 and protrudes from the upper roller 23. Specifically, multiple first left guide wheels 42 and multiple first right guide wheels 44 are provided. By providing the first guiding mechanism 4, when the pallet is conveyed to the upper roller 23, one side of the pallet can abut against the first left guide wheel 42, and the other side of the pallet can abut against the first right guide wheel 44, thereby making the pallet move more stably.

[0028] This invention also includes a second guiding mechanism 5, which comprises a second left connecting seat 51, a second left guide wheel 52, a second right connecting seat 53, and a second right guide wheel 54. The second left connecting seat 51 is fixed to one side of the lifting frame 1, and the second left guide wheel 52 is rotatably mounted on the second left connecting seat 51, protruding from the lower roller 24.

The lifting cylinder 33 is mounted on the lifting seat 31 and is connected to the lifting plate 34 to drive the lifting plate 34 to rise and fall.

[0031] When the lifting frame 1 needs to rise, the lifting cylinder 33 drives the lifting plate 34 to rise, and the lifting plate 34 abuts against the bottom of the lifting frame 1. The rise of the lifting plate 34 synchronously drives the lifting frame 1 to rise. When the lifting frame 1 rises or falls, the first wheel 323 rolls along the bottom of the lifting plate 34, and the second wheel 324 rolls along the lifting seat 31, thereby making the lifting frame 1 more stable when rising or falling.
