During pushing, the electric clamp 124 automatically opens, and the pushing frame 123 is displaced toward the plate fixed-length bottom plate 11 under the action of the first electric telescopic cylinder 122 until one end of the plate located on the top surface of the plate fixed-length bottom plate 11 enters the interior of the electric clamp 124. At this time, the electric clamp 124 automatically closes and clamps it. Subsequently, under the push of the pushing frame 123, the electric clamp 124 drives the plate to move to realize automatic pushing. The automatic pushing structure 12 provided is suitable for automatic pushing of plates of different sizes and thicknesses.

[0031] The length meter structure 13 is composed of a body 131 and an alignment assembly 132.

[0039] The working process of the utility model is as follows: before loading, the L-shaped plate alignment seat 1321 is continuously raised under the action of the second electric telescopic cylinder 1322 until the L-shaped plate alignment seat 1321 reaches the top of one side of the outer surface of the leather wheel 1311, and then loading is carried out, and the plate can be pushed by the automatic pushing structure 12 so that the plate and the L-shaped plate alignment seat 1321 are aligned and fit, so that the edge of the plate is located on the top surface of the leather wheel 1311, and automatic zeroing is achieved. After the alignment and zeroing are completed, the L-shaped plate alignment seat 1321 is automatically reset and stored at the bottom of one side of the outer surface of the leather wheel 1311, and then the electric clamp 124 drives the plate under the push of the pushing frame 123. Displacement occurs to achieve automatic pushing, and during the pushing process, the leather wheel 1311 located at the bottom of the plate rotates under the displacement of the plate. After a certain length of displacement, the length encoder 1312 sends an electrical signal to the PLC controller 14. At this time, the first electric telescopic cylinder 122 stops working and stops pushing. After the plate enters the plate inlet 22, it is first fixed and limited by the plate spring positioner 24 under the action of the hydraulic telescopic mechanism 23, and then the plate shearing blade is sheared by the blade driving mechanism, and then the blade and the plate spring positioner 24 are reset, and the operation is repeated continuously to realize the automatic fixed-length shearing processing and production operation of the plate.
