Working principle: When trimming the pp tableware, first start the motor 2, the motor 2 drives the threaded rod 3 to rotate, and through the thread transmission, the threaded rod 3 and the positioning sleeve 6 cooperate to produce a lifting movement, and the positioning sleeve 6 drives the second straight rod. The rod 904 and the edge trimming knife 7 move downward at the same time. When the edge of the edge trimming knife 7 is tangent to the worktable 8, and during the trimming operation for the pp tableware, the second straight rod 904 moves downward to the first straight rod 903. Squeeze, drive the connecting piece 902 and the connecting rod 905 to move downward, and at the same time drive the first piston 906 and the second piston 907 to move downward, because the sides of the first piston 906 and the second piston 907 are in contact with the inner wall of the piston groove 909 , the top of the piston groove 909 generates negative pressure, and the cut waste is sucked into the piston groove 909 and falls into the top of the second piston 906, and because the bottom of the piston groove 909 has a larger cross-sectional area than the top, in the downward movement of the piston, the first The air pressure between the first piston 906 and the second piston 907 decreases. When the first piston 906 descends into the large groove, the waste chips are sucked into the large groove due to the low air pressure in the large groove, and the waste chips fall into the top of the second piston 907. When the second piston 907 moves to the point where the bottom is in contact with the bottom of the piston groove 909, the air pressure between the first piston 906 and the second piston 907 disappears from the discharge port 910, and the scraps cut off under the action of the fan enter from the discharge port 910 In the waste collection box 911, the trimming knife 7 rises up through the return spring 901 to drive the connecting piece 902 to lift up, so that the piston is reset, so as to achieve the purpose of automatically and continuously collecting the trimming waste.

To sum up, the PP tableware edge trimming equipment after extrusion molding is used to trim the PP tableware downward through the edge trimming knife 7, and the second straight rod 904 is driven by the positioning sleeve 6 to move downward. When the table 8 is tangent, the second straight rod 904 pushes down the first straight rod 903, the connecting piece 902 drives the connecting rod 905 to move downward, and simultaneously drives the first piston 906 and the second piston 907 to move downward, The top of the piston groove 909 generates negative pressure, and the cut waste is sucked into the piston groove 909. When the first piston 906 moves to the bottom of the piston groove 909, the air pressure disappears and the cut waste enters the waste from the discharge port 910. In the chip collection box 911, the effect of automatically collecting trimming waste is achieved.
