DETAILED DESCRIPTION

[0018] The specific embodiment of the utility model is further explained below in combination with the drawings.

[0019] As Figures 1-6As shown, a paperboard die cutting machine blanking mechanism, including the base table 1, the lower die plate 2 is installed on the base table 1, the top plate 3 is arranged above the base table 1, the vertical column 4 is arranged between the top plate 3 and the base table 1, the upper die plate 5 is arranged above the lower die plate 2, the hydraulic cylinder 6 is arranged above the top plate 3, the output end of the hydraulic cylinder 6 is fixedly connected with the upper die plate 5 after penetrating through the top plate 3, the slide sleeve 7 is arranged on the side of the upper die plate 5, the slide sleeve 7 is slidably connected with the vertical column 4, the guide rod 8 is arranged on the upper surface of the base table 1 and located on both sides of the lower die plate 2, and the push plate 9 is arranged, the both ends of the push plate 9 are respectively provided with the sleeve 10 which is slidably connected with the guide rod 8, the first spring 11 is sleeved on the guide rod 8, the side plate 12 is rotatably connected on the push plate 9, one end of the side plate 12 is provided with a deflection part, the limiting plate 13 is arranged on the sleeve 10, the limiting plate 13 is connected with the other end of the side plate 12 through the elastic element 14, the vertical plate 15 is arranged on the slide sleeve 7 on both sides of the upper die plate 5, and the guide plate 16 is arranged on the bottom of the vertical plate 15.

[0020] When the first spring 11 is in the maximum stretching state on the guide rod 8, the push plate 9 is located on the side of the lower die plate 2, when the paperboard is placed on the lower die plate 2, one end of the paperboard can be abutted and aligned with the push plate 9, then the paperboard can be die cut by the upper die plate 5 and the lower die plate 2 only by moving the paperboard left and right along the push plate 9, two corresponding mark points can be arranged on the upper surface of the push plate 9, and the both ends of the paperboard can be aligned with the mark points, so that the placing efficiency and the placing accuracy of the paperboard can be improved.

[0021] After the paperboard is placed, the hydraulic cylinder 6 is started, the output end of the hydraulic cylinder 6 is stretched out and pushes the upper die plate 5 to move downward, the upper die plate 5 drives the slide sleeve 7 to move downward along the vertical column 4, when the slide sleeve 7 moves downward, the vertical plate 15 and the guide plate 16 are driven to move downward, when the guide plate 16 moves downward, the lower surface of the guide plate 16 will contact the deflection part and continuously extrude the deflection part, under the extrusion of the guide plate 16, the deflection part and the side plate 12 will rotate, so that the guide plate 16 can completely pass through the deflection part, when the guide plate 16 completely passes through the deflection part, the upper die plate 5 and the lower die plate 2 also complete the die cutting of the paperboard, at the same time, under the action of the elastic element 14, the deflection part is reset, the deflection part and the side plate 12 cannot continue to rotate when the side plate 12 abuts against the limiting plate 13 in the resetting process, the side plate 12 and the deflection part are both in a horizontal state at this time;

[0022] When the output end of the hydraulic cylinder 6 drives the upper die plate 5 to move upward, the sliding sleeve 7 drives the vertical plate 15 and the guide plate 16 to move upward, when the guide plate 16 moves upward, the upper surface of the guide plate 16 will abut against the deflection part, and due to the limitation of the limiting plate 13, the upper surface of the guide plate 16 continuously maintains contact with the deflection part, and since the upper surface of the guide plate 16 is inclined, when the guide plate 16 moves upward, the guide plate 16 will drive the sleeve 10 on the push plate 9 to move along the guide rod 8 through the deflection part, and continuously press the first spring 11, when the guide plate 16 rises to a certain height, the push plate 9 moves a distance on the upper surface of the lower die plate 2, and in the moving process, the push plate 9 pushes the paperboard that has completed the die cutting on the lower die plate 2 out of the lower die plate 2, only more than half of the paperboard needs to be pushed out of the lower die plate 2, and the paperboard will slide out of the lower die plate 2 due to the center of gravity not being on the lower die plate 2, and when the guide plate 16 continues to move upward, the deflection part will move out of the lower end of the guide plate 16, and under the action of the first spring 11, the push plate 9 is reset, at this time, it is convenient to continue to place the paperboard on the lower die plate 2.

[0023] The elastic member 14 can be a rubber rope or a tension spring with elasticity.

[0024] Further, the deflection part includes a frame 17 arranged at one end of the side plate 12, and a roller 18 is arranged in the frame 17, when the guide plate 16 moves upward, the outer surface of the roller 18 will continuously contact the upper surface of the guide plate 16, and the roller 18 will roll on the upper surface of the guide plate 16, so as to reduce the friction between the deflection part and the guide plate 16, and facilitate the movement of the push plate 9.

[0025] Further, when the push plate 9 moves on the guide rod 8 through the sleeve 10, the push plate 9 does not contact the upper surface of the lower die plate 2, avoiding the friction between the push plate 9 and the lower die plate 2 to damage the lower die plate 2.

[0026] Further, the second spring 19 is arranged on the column 4, and the second spring 19 is located between the sliding sleeve 7 and the base 1, so as to improve the stability of the upper die plate 5 when moving up and down.

[0027] Further, the side portions of the lower die plate 2 and the base 1 are respectively provided with a sink, and a threaded hole is arranged in the sink, further comprising a connecting plate 20 provided with two through holes, and a bolt 21 for fixing the connecting plate 20 to the lower die plate 2 and the base 1 respectively.

[0028] In the description of the utility model, unless another definite provision and limit, term " install " " link " " connection " should do broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electric connection, can be direct connection, also can indirectly connect through intermediate medium, can be two element internal communication. For ordinary skilled person in the art, the above-mentioned term can be understood in the specific meaning in the utility model according to specific circumstances.
