[0008] The principle and effects of the technical scheme are as follows:

[0009] Firstly, the material boards to be punched are stacked in the feeding channel, the motor is started, the sliding block is driven to move along the guide rail towards the punching table through the transmission mechanism, when the sliding block drives the L-shaped frame to pass through the limiting frame, the vertical rod of the L-shaped frame abuts against the side wall of the material board, and the top of the sliding block limits the horizontal rod of the L-shaped frame from rotating clockwise, so that the L-shaped frame drives the lowermost material board to move towards the punching table, when the sliding block moves to the position closest to the punching table, the vertical rod of the L-shaped frame abuts against the side wall of the punching table, the dial is continuously rotated to drive the sliding block to perform a reset movement, at this time, the punching machine is started to complete the punching work, when the sliding block drives the L-shaped frame to pass through the limiting frame again, the top of the sliding block cannot limit the horizontal rod of the L-shaped frame from rotating counterclockwise, so that the L-shaped frame rotates until the top of the vertical rod of the L-shaped frame rotates to the bottom of the material board and slides along the bottom of the material board, when the top of the vertical rod of the L-shaped frame is separated from the material board, the L-shaped frame rotates clockwise due to gravity until the top of the sliding block abuts against the horizontal rod of the L-shaped frame, and the above operation is repeated to continuously feed the material boards.

[0010] Through the above arrangement, the worker only needs to stack the material boards in the feeding channel to complete the continuous feeding work, so that the operation steps are simplified, the work efficiency is improved, and the occupied area during work is reduced.

[0011] In the utility model, the transmission mechanism comprises a dial and a connecting rod, the dial is fixedly sleeved on the output end of the motor, a round pin is fixedly arranged on the side wall of the dial, one end of the connecting rod is rotationally sleeved on the round pin, and the other end of the connecting rod is rotationally connected with the side wall of the sliding block. Through the above arrangement, the sliding block is driven to reciprocate along the guide rail.

[0012] The height difference between the lower edge of the limiting frame and the bottom of the sliding groove is h1, the thickness of the material plate is h2, the maximum height difference between the top of the vertical rod of the L-shaped frame and the bottom of the sliding groove is h3, h2≤h1<2h2 is set, and h3<h2.

[0013] In the utility model, the bottom of the limiting frame far from the punching table is fixedly provided with a limiting block along the vertical direction on both sides of the through groove. Through the above setting, the L-shaped frame can be prevented from moving away from the punching table during the resetting of the sliding block.

[0014] In the utility model, a tension spring is arranged between the bottom of the horizontal rod of the L-shaped frame and the top of the sliding block, and a protrusion is further fixedly arranged on the bottom of the horizontal rod of the L-shaped frame far from the connecting block.

[0015] Principles and effects of the technical scheme:

[0016] When the sliding block drives the L-shaped frame to move away from the punching table and passes through the limiting frame, the L-shaped frame rotates, and the top of the vertical rod of the L-shaped frame slides along the bottom of the material plate. At this time, the tension spring is stretched, so that the tension spring has elasticity. When the L-shaped frame is separated from the material plate, the tension spring drives the L-shaped frame to rotate in the clockwise direction until the protrusion abuts against the top of the sliding block. At this time, the tension spring does not have elasticity.

[0017] Through the above setting, the L-shaped frame can be prevented from being unable to reset due to the friction force between the L-shaped frame and the connecting block after the L-shaped frame is separated from the material plate, thereby preventing the material plate from being pushed again, and the practicability of the utility model is improved.

[0018] In the utility model, an inclined discharging table is fixedly arranged below the upper edge of the punching table far from the limiting frame, and the sliding groove penetrates to the end of the punching table far from the limiting frame.

[0019] Principles and effects of the technical scheme:

[0020] After completing a punching work, the L-shaped frame continues to push the next material plate to be punched to move towards the punching table. In the process that the next material plate to be punched moves to the predetermined position, the cut material plate and the finished product are pushed onto the discharging table.

[0021] Through the above setting, the utility model can automatically and continuously discharge, the cut material plate and the finished product are prevented from being manually taken out from the punching machine, and the safety of the utility model is further improved.

[0022] In the utility model, the two side walls of the sliding groove are respectively recessed with mounting grooves near the end of the discharging table, a torsion spring shaft is arranged in the mounting groove along the vertical direction, and a movable plate is arranged outside the torsion spring shaft.

[0023] Principles and effects of the technical scheme:

[0024] The cut-off material plate and the finished product are pushed away from the movable plate by the next material plate to be punched, and when the center of gravity of the cut-off material plate and the finished product is separated from the punching table, the cut-off material plate and the finished product fall onto the upper surface of the discharging table, and the movable plate is reset under the action of the torsion spring shaft until the side wall of the next material plate to be punched abuts against the movable plate, and the movable plate limits the next material plate to be punched from moving continuously due to inertia under the action of the torsion spring shaft.

[0025] Through the above setting, the material plate to be punched can be prevented from deviating from the predetermined position due to inertia, and the punching effect is ensured.

[0026] In the utility model, the top of the vertical rod of the L-shaped frame away from the punching table is provided with an arc-shaped guide surface. Through the above setting, the top of the vertical rod of the L-shaped frame can be prevented from scratching the material plate, and the practicability of the utility model is improved.
