Sheet material feeding and conveying device

Abstract

The invention relates to a sheet material feeding and conveying device. The sheet material feeding and conveying device comprises a rack which is located on the two sides of a conveying production line and provided with stand columns, a lifting machine base is arranged on the lower portion of the rack, a row of transmission rollers used for supporting stacked sheets is arranged on the machine base, sling chains are connected beside the front side and the rear side of the machine base respectively and used for driving the machine base to ascend and descend, the sling chains stride transmission chain wheels on the rack respectively, and a sling sinker used for balancing weight is arranged at the outer side end of each sling chain; the front transmission chain wheel and the rear transmission chain wheel on the same side are driven by a same stepping motor transmission mechanism; the front side and the rear side of the upper portion of the machine base are respectively provided with a lifting sucker used for adsorbing the sheets, the lifting sucker on the front side is connected with a transverse air cylinder connected to the rack so that the lifting sucker on the front side can be driven to move front and back in a reciprocating mode, the front side of the lifting sucker on the front side is provided with a pair of horizontal rollers used for drawing the sheets to move forward, and the output end of each horizontal roller is provided with a sheet conveying device. Not only is the sheet material feeding and conveying device beneficial for guiding a sheet bearing base from the production line, but also lifting control and transmission are convenient and accurate, and feeding is smooth.

Description

technical field [0001] The invention relates to a sheet material feeding and conveying device. Background technique [0002] The thin plate feeder in the can body production line has a certain height due to the plastic sucker that absorbs the thin plate. The plastic sucker needs to be lifted to a certain position before the plastic sucker can absorb the thin plate. The existing thin plate lifting device is usually manually adjusted to form a stack of thin plates. However, manual adjustment is likely to cause insufficient height. The plastic suction cup cannot absorb the thin plate, or the height of the rise is too high. The plastic suction cup is easily damaged when it hits the thin plate. It needs to be stopped for adjustment. , low work efficiency.

[0002] The thin plate feeder in the can body production line has a certain height due to the plastic sucker that absorbs the thin plate. The plastic sucker needs to be lifted to a certain position before the plastic sucker can absorb the thin plate. The existing thin plate lifting device is usually manually adjusted to form a stack of thin plates. However, manual adjustment is likely to cause insufficient height. The plastic suction cup cannot absorb the thin plate, or the height of the rise is too high. The plastic suction cup is easily damaged when it hits the thin plate. It needs to be stopped for adjustment. , low work efficiency

[0003] The thin sheets need to be conveyed one by one during the conveying process, so as to facilitate the processing of the subsequent process. However, during the conveying process of the existing transmission belt, due to the long-term use of its upper end surface, the friction force decreases, and the thin sheets will slip on the conveying belt. It cannot be conveyed forward with the conveyor belt, and scratches or jams will occur, resulting in high loss of thin sheets and low production efficiency, especially when producing aluminum sheets, even if a magnet is installed on the bottom side of the conveyor belt, the slippage cannot be overcome
