[0008] As a further improvement of the present invention, the unloading mechanism includes a slide plate slidably connected to the inside of the sliding cavity, the upper end of the slide plate is fixedly connected to a push rod, the push rod passes through the inner top wall of the sliding cavity and extends to the inside of the extrusion cavity, the upper end of the slide plate is fixedly connected to a first magnetic block, the lower end of the vertical rod is fixedly connected to a second magnetic block, the inner side wall of the extrusion cavity is rotatably connected to a side push plate through a torsion spring, the side wall of the side push plate is fixedly connected to a traction rope, the end of the traction rope away from the side push plate passes through the machine body and extends to the inside of the sliding cavity, the end of the traction rope located in the sliding cavity is fixedly connected to a connecting block, the traction rope is mounted with a second spring, one end of the second spring is connected to the inner top wall of the sliding cavity, and the other end of the second spring is connected to the connecting block.

[0011] As a further improvement of the present invention, a shift rod is fixedly connected to the inner top wall of the fixed frame, the shift rod passes through the movable plate, and the movable plate is slidably connected to the shift rod.

[0012] Beneficial effects of the present invention: 1. By setting up a feeding mechanism, the material rod is inserted into the loading sleeve and fixed by a locking bolt. By contracting the stepping telescopic rod, the material rod can be driven to move a fixed distance each time, thereby realizing automatic feeding of the material rod to the support block.

[0013] 2. By setting up a rotating mechanism, the extension of the hydraulic cylinder can drive the vertical rod to move downward. Due to the one-way bearing, the vertical rod will not drive the turntable to rotate when it moves downward, and thus will not affect the slitting and extrusion molding of the material rod. When the hydraulic cylinder drives the vertical rod to move upward, when the movable plate approaches the top of the fixed frame, it can drive the turntable to rotate counterclockwise, so that the material rod on the right side that has been slit can be transferred to the bottom of the extrusion head. When the support block contacts the cushion block, it is pushed up by the cushion block to lift and tilt the support block, so that the material rod in the support block falls into the extrusion cavity through the discharge chute, and the material rod slitting and loading can be completed continuously and automatically without manual loading.

[0014] 3. By setting up a cutting machine and a clamping mechanism, when the hydraulic cylinder is extended, it can drive the movable plate to move downward, and the pressing block is pressed on the material rod. The elastic force of the first spring applies downward pressure to the pressing block to press the material rod, thereby ensuring the stability of the material rod during slitting. By continuing to move the movable plate downward, the cutting machine can be driven to complete slitting of the material rod. While slitting the material rod, the extrusion head can be driven downward to complete the extrusion molding of the material rod inside the extrusion cavity. The slitting and extrusion molding of the material rod are carried out simultaneously, thereby effectively improving the processing efficiency.

[0015] 4. By setting up the unloading mechanism, when the vertical rod moves down to the bottom of the sliding cavity, the first magnetic block is magnetically connected with the second magnetic block. When the vertical rod moves up, it can drive the slide plate to move up, and then drive the ejection rod to first lift the extruded cover terminal. When the slide plate moves up and contacts the connecting block, it can drive the connecting block to move up. At this time, the traction rope is relaxed, and the side push plate rotates to the left under the action of the torsion spring, so that the lifted cover terminal can be pushed to the left to the unloading port, thereby realizing automatic unloading of the cover terminal.

[0016] The present invention can realize continuous and automatic completion of the slitting and extrusion molding of the material rod, and can realize automatic unloading of the cover terminal after extrusion molding without manual intervention, and the overall processing automation degree is high and the efficiency is high.
