Roller adjustment and pressing mechanism of sheet material feeding device

technical field

The invention belongs to a sheet material feeding device, in particular to a roller adjusting and pressing mechanism of the sheet material feeding device.

Background technique

The shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to the other blade to cut the plate. One of the important steps in the working process of the shearing machine is to convey the processed plate. The traditional conveying method is manual conveying. The feeding process relies entirely on the operator's operating experience to feed the plate. This feeding method takes time and Laborious, feeding efficiency is not high.

In order to solve the above problems, people have designed an automatic feeding device, through which the plate is transported, that is to say, the plate is transported to the cutter of the shearing machine. However, there is another problem in the conveying process of the plate, that is, it is easy to deviate during the conveying process of the plate, which affects the feeding accuracy.

In order to solve the problem of feeding accuracy, Chinese patent CN101259625A provides a "sawmill clamping and feeding mechanism", which includes a chuck for clamping the wood to be processed. a bump.

After the processed wood is clamped by the chuck, the clamping firmness between the processed wood and the chuck is increased through the protrusion on the chuck. In this way, the processed wood is not easy to loosen, thereby realizing high feeding accuracy and the situation that the wood will not shift during the feeding process.

However, during the conveying process of the metal sheet by the above-mentioned feeding mechanism, since the protrusions cannot be embedded on the metal sheet, there is still a problem of easy deviation during the conveying process of the metal sheet. Moreover, the plate to be conveyed will be damaged under the action of the protrusion.

Similar problems also exist in other existing feeding devices.
