[0020] The present invention is further described below with reference to specific embodiments. Figure 1 —4:

[0021] A pulp product trimming device comprises a frame 1, on which a working platform 2 and a plurality of placement mold grooves 3 are provided, which are opened on the top surface of the working platform 2 and are used to place pulp products; a lifting and trimming seat 4 is provided on the frame 1 directly above the working platform 2 and is movable up and down; a trimming mold body 5 corresponding to the placement mold groove 3 and an edge cutter 6 surrounding the outer periphery of the trimming mold body 5 are provided on the bottom surface of the lifting and trimming seat; a molding cavity corresponding to the pulp product is formed between the trimming mold body 5 and the placement mold groove 3.

[0022] The utility model has a high degree of automation. The pulp product is placed in the placement mold groove 3 and is pressed down onto the working platform 2 with the help of the lifting trimming seat 4, so that the edge cutter 6 can cut and trim the outer edge of the paper blank in the placement mold groove 3. In addition, the trimming mold body 5 and the placement mold groove 3 can further press and shape the pulp product. Compared with the existing technology, the utility model has high processing efficiency and better trimming quality.

[0023] In order to enable the lifting and trimming seat 4 to move up and down stably on the frame 1, a plurality of vertical guide columns 7 are vertically arranged on the frame 1, and the lifting and trimming seat 4 is slidably connected to the vertical guide columns 7, and the lifting and trimming seat 4 is driven by the lifting drive assembly to move up and down along the vertical guide columns 7.

[0024] At the same time, the lifting drive assembly can directly adopt the existing screw nut assembly, and in this embodiment, the specific structure adopted by the lifting drive assembly is: the lifting drive assembly includes a servo motor 8 fixed on the frame 1, and the output shaft of the servo motor 8 is transmitted and matched with the crankshaft 10 rotatably connected to the frame 1 through the gearbox 9, and the eccentric part of the crankshaft 10 is hinged to the upper end of the transmission connecting rod 12, and the lower end of the transmission connecting rod 12 is connected to the driving seat 11, and the two side parts of the lifting trimming seat 4 are hinged to the lower end of a first hinge rod 13, and the upper ends of the two first hinge rods 13 are respectively hinged to the lower end of a second hinge rod 14, and the hinges of the two first hinge rods 13 and the second hinge rods 14 are respectively hinged to the left and right side parts of the driving seat 11 through the linkage connecting rod 15, and the upper ends of the two second hinge rods 14 are hinged to the frame 1.

In this embodiment, the cleaning assembly includes a flat push scraper 17 slidably connected to the frame 1. The flat push scraper 17 is located on one side of the working platform 2. The flat push slide is driven by the power assembly to move to the top of the working platform 2. The lower end of the flat push scraper 17 can push the pulp waste horizontally on the top surface of the working platform 2. A receiving container 18 for receiving the pulp waste is provided on the other side of the working platform 2. At the same time, in order to remove the pulp product adsorbed on the trimming mold 5 and transfer it to the next process, a material return conveyor belt assembly 19 is provided on the frame 1 located on one side of the working platform 2. A material return moving frame 20 that can be moved between the working platform 2 and the lifting trimming seat 4 is slidably connected to the material return conveyor belt assembly 19. A plurality of linkage shafts 21 are connected to the material return moving frame 20 for longitudinal rotation. The linkage shafts 21 are provided with negative pressure suction nozzles 22 corresponding to the trimming mold 5. It should be noted that, in this embodiment, the flat push scraper 17 is fixed to the end of the material return moving seat, and the flat push scraper 17 is driven to move horizontally by the material return moving frame 20. The negative pressure suction nozzle 22 can absorb the pulp product on the trimming mold body 5, and place the pulp product on the material return conveyor belt assembly 19 by turning it over.

[0028] Furthermore, in the present embodiment, the rotation driving structure of the linkage shaft 21 is as follows: a linkage gear is mounted on one end of each linkage shaft 21, a driving gear 23 corresponding to and meshing with the linkage gear is rotatably connected to the frame 1, a driving cylinder 24 is hinged on the frame 1, a transmission rod 25 is hinged at the telescopic end of the driving cylinder 24, and the transmission rod 25 is eccentrically hinged on each driving gear 23.
