[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a trimming device for plastic products, including a base 1, a first support plate 2 fixedly connected above the base 1, a cylinder 3 fixedly connected above the inner side of the first support plate 2, an air rod 4 fixedly connected to the output end of the cylinder 3, a connecting plate 5 fixedly connected to the lower end of the air rod 4, a closing tool 6 fixedly connected to the lower end of the connecting plate 5, a sliding mechanism 7 is arranged inside the first support plate 2, and a pushing mechanism 8 is arranged on one side of the sliding mechanism 7 close to the closing tool 6;

[0021] The interior of the first support plate 2 is provided with a first hole 9. The sliding mechanism 7 includes a first push rod 701 disposed inside the first hole 9. The vertical width of the first hole 9 is greater than that of the first push rod 701, and the inner surface of the first hole 9 fits against the outer surface of the first push rod 701, such that the first push rod 701 does not wobble when moving vertically inside the first hole 9. A first guiding groove 702 communicates with the inner wall of the first hole 9. Point a is provided on the outer side above the inner wall of the first guiding groove 702, point b is provided on the inner side above the inner wall of the first guiding groove 702, point c is provided on the outer side below the inner wall of the first guiding groove 702, and point d is provided on the inner side below the inner wall of the first guiding groove 702. A first guiding rod 704 is disposed inside the first guiding groove 702. The first guiding rod 704 is fixedly connected to the first push rod 701. A second hole 705 is provided inside the closing cutter 6. The outer appearance structure of the first push rod 701 is a cuboid, and the outer side surface of the first push rod 701 fits against the inner surface of the second hole 705, such that the first push rod 701 does not rotate when moving inside the second hole 705. Point a of the first guiding groove 702 is farther from the closing cutter 6 than point b of the first guiding groove 702, and point c of the first guiding groove 702 is closer to the closing cutter 6 than point d of the first guiding groove 702. When the first guiding rod 704 moves to point a of the first guiding groove 702 and moves downward, the first guiding rod 704 can move to the rear side of the first guiding groove 702. When the first guiding rod 704 moves to point c of the first guiding groove 702 and moves upward, the first guiding rod 704 can move to the front side of the first guiding groove 702.

[0022] One end of the pushing mechanism 8 away from the first guiding groove 702 is fixedly connected to a first push plate 801. A guiding hole 802 is provided inside the first push plate 801. A second guiding rod 803 is disposed inside the guiding hole 802. One end of the second guiding rod 803 is fixedly connected to a second push rod 804. The outer appearance structure of the second push rod 804 is a cuboid, and the central axis of the second push rod 804 is parallel to the central axis of the air rod 4. Moreover, the outer side surface of the second push rod 804 fits against the inner side surface of the third hole 806, such that the second push rod 804 does not rotate when moving inside the third hole 806. The lower end of the second push rod 804 is fixedly connected to a second push plate 805. A third hole 806 is provided inside the connecting plate 5. The second push rod 804 is nested inside the third hole 806. The outer appearance structure of the guiding hole 802 is an inclined straight line, and the guiding hole 802 and the second guiding rod 803 are in clearance fit, such that the guiding hole 802 can push the second guiding rod 803 to move vertically when moving horizontally.

[0023] When trimming plastic products is required, place the plastic product at the corresponding position of the base 1, start the cylinder 3 to drive the air rod 4 to move downward, drive the connecting plate 5 and the closing cutter 6 to move downward, drive the first push rod 701 to move downward, so that the first guide rod 704 moves downward along the track of the first guide groove 702. After the closing cutter 6 finishes trimming the plastic product, the cylinder 3 moves upward, so that the first guide rod 704 moves upward along the track of the first guide groove 702. Since point a of the first guide groove 702 is farther from the closing cutter 6 than point b of the first guide groove 702, and point c of the first guide groove 702 is closer to the closing cutter 6 than point d of the first guide groove 702, when the first guide rod 704 moves upward at point c, it will move forward along the hypotenuse of the first guide groove 702, driving the first push plate 801 and the guide hole 802 to move forward. Since the external structure of the guide hole 802 is an inclined straight line and the matching mode between the guide hole 802 and the second guide rod 803 is a clearance fit, the second guide rod 803 moves downward along the track of the third hole 806, pushing the second push plate 805 downward to push out the plastic product stuck on the inner wall of the closing cutter 6, without the need for manual removal.
