Claims

1. An automatic push feeding mechanism, comprising a machine box, a workbench, a cutter assembly and a feeding roller mechanism, the upper end of the machine box is provided with the workbench, and the middle part of the workbench is provided with the cutter assembly, characterized in that, Feeding roller mechanisms are provided on both sides of the tool assembly. The feeding roller mechanism includes a roller support, a lower pressure cylinder, an upper pressure roller, a lower pressure roller, and a transmission chain. The roller support is fixedly mounted on the worktable. A lower pressure roller is provided below the worktable. The lower pressure roller is connected to a motor through the transmission chain, and the motor drives the lower pressure roller to rotate. A lower pressure cylinder is installed on the upper end of the roller support above the worktable. The piston rod end of the lower pressure cylinder is connected to the upper pressure roller. The lower pressure cylinder drives and controls the upper pressure roller to move up and down.

2. An automatic push feed mechanism according to claim 1, wherein The lower roller has a sprocket coaxially mounted on its end shaft. The sprocket is meshed with a transmission chain, which is connected to a motor. A speed reducer is installed between the motor and the transmission chain. An adjustment mechanism is installed between the speed reducer's mounting plate and the machine housing. The transmission chain is tensioned by the adjustment mechanism and the speed reducer's own weight.

3. An automatic push feed mechanism according to claim 1 wherein, Two sets of feeding roller mechanisms are respectively arranged at intervals on the worktables on both sides of the tool assembly.

4. An automatic push feed mechanism according to claim 3, wherein The feeding roller mechanisms are all arranged in parallel at intervals. The lower rollers of the four feeding roller mechanisms are connected in sequence by four sets of double-row transmission chains arranged in the horizontal direction, so that the four sets of lower rollers rotate synchronously.

5. An automatic push feed mechanism according to claim 4, wherein A chain tensioning device with a tension spring structure is installed in the middle of the four sets of double-row drive chains arranged in the horizontal direction to tighten the chain over the middle long distance.

6. An automatic feeding mechanism according to claim 1, characterized in that, The pressure roller support includes a fixed frame, guide columns, and a guide bracket. The fixed frame is fixedly mounted on the upper end of the machine housing. The cylinder body of the pressure cylinder is fixedly mounted on the fixed frame. The piston rod of the pressure cylinder extends downward into the fixed frame and is fixedly connected to the guide bracket, thereby driving the guide bracket to move up and down. The guide bracket is set inside the fixed frame, and the pressure roller is connected inside the guide bracket. The pressure roller can rotate freely inside the guide bracket. Two guide rods are fixedly connected to the upper end of the guide bracket. The guide rods pass vertically upward through the through holes on the fixed bracket.

7. An automatic push feed mechanism according to claim 1 wherein, Both the upper and lower pressure rollers are knurled pressure rollers.

8. An automatic push feed mechanism according to claim 1 wherein, The workbench surface is flat and smooth.
