[0012] The utility model will be further described below in conjunction with the accompanying drawings.

[0013] like Figure 1 , 3 As shown, a plate feeding machine with a tensioning device comprises a frame 1, wherein the frame has a left feed end and a right discharge end, a feed roller 2 is installed at the feed end, a discharge roller 3 is installed at the discharge end, and a plurality of winding rollers 4 are installed on the frame; it is characterized in that: it also comprises a lever frame 5 installed on the frame, the lever frame comprises two levers 51 on both sides, the front end of the lever is hinged on the frame, and there is a tensioning roller 52 connected at both ends in the middle of the lever, and there is a connecting rod 53 connected at the rear ends of the two levers, and also comprises one or more counterweights 54 that can be suspended on the connecting rod.

[0014] When the utility model is used, the material plate 10 enters through the feed roller, passes through the winding roller, and then passes through the downward pressure of the tensioning roller, so that the material plate can be tightened, so that the material plate undergoes a certain deformation, and the purpose of the utility model can be achieved; the following embodiments are the same. The multiple counterweights that can be hung on the connecting rod can be selected and used according to the processing of different types of material plates to meet different production requirements.

[0015] like Figure 2 , 3As shown, there is another technical solution: a plate feeder with a tensioning device, comprising a frame 1, the frame having a feed end on the left and a discharge end on the right, a feed roller 2 is installed at the feed end, a discharge roller 3 is installed at the discharge end, and a plurality of winding rollers 4 are installed on the frame; it is characterized in that: it also includes a lever frame 5 installed on the frame, the lever frame includes two levers 51 on both sides, the front end of the lever is hinged on the frame, and there is a tensioning roller 52 connected at both ends in the middle of the lever, and a connecting rod 53 is connected to the rear ends of the two levers, and an adjustable tension member 55 is connected to the connecting rod and the frame.
