Problems solved by technology
[0002] During the production process of thermoplastic sheets, it is often necessary to adjust the gap between various rollers. The existing adjustment is mainly through the air cylinder or hydraulic cylinder. Due to the instability of the air cylinder and hydraulic control, multiple adjustment points are caused. There are errors between them, causing the machine to be stuck easily, and the products produced have errors

The invention belongs to the field of production equipment of thermoplastic boards, and particularly relates to a lifting mechanism used for ascending and descending of a board lifting pressing-levelling mechanism at the same time. The lifting mechanism comprises stand columns arranged at the four corners of a platform, wherein horizontal tensioning rods are arranged between the upper stand column and the lower stand column, three vertical tensioning rods are arranged between the horizontal tensioning rods, a power device is arranged in the middle of the second vertical tensioning rod, the positions, on the upper side and the lower side of the power device, of the second vertical tensioning rod are respectively provided with an upper transmission shaft and a lower transmission shaft, the power device is connected with the upper transmission shaft and the lower transmission shaft simultaneously, the first vertical tensioning rod and the third vertical tensioning rod are respectively provided with a worm and gear speed reducer, the two ends of the upper transmission shaft and the two ends of the lower transmission shaft are connected with the input ends of the worm and gear speed reducers respectively, the worm and gear speed reducers are arranged on the first vertical tensioning rod and the third vertical tensioning rod, the output end of each worm and gear speed reducer is provided with a transmission rod, and the transmission rods are connected with workpieces to be lifted. The four corners of the lifting mechanism can move up and down synchronously.
Description
technical field [0001] The invention belongs to the field of production equipment of thermoplastic plates, and in particular relates to a lifting mechanism for lifting and lowering a pressing mechanism of plates while going up and down. Background technique [0002] During the production process of thermoplastic sheets, it is often necessary to adjust the gap between various rollers. The existing adjustment is mainly through the air cylinder or hydraulic cylinder. Due to the instability of the air cylinder and hydraulic control, multiple adjustment points are caused. There are errors between them, causing the machine to be prone to jamming, and there are errors in the products produced. Contents of the invention [0003] The present invention aims at the deficiencies of the prior art. The present invention designs a lifting mechanism with four corners that can move up and down synchronously. In the present invention, a mechanical structure is used for transmission, which e...
